Abstract: A vehicle adapted for transporting and manipulating objects within a confined space, such as a tunnel. The vehicle comprises a pair of side frames interconnected by vertically adjustable front and rear interconnecting members that include horizontal portions onto which a boom is slideably and pivotally connected. Raising and lowering of one or two of the interconnecting members and laterial traversing of one or two of the connected boom portions provides for manipulation of an object or tool attached to the boom.

Abstract: An improved railroad stub switch is described in which the axial rail tension or compression forces due to temperature fluctuations are transmitted through the switch by means of radius arms connected to both the switch and fixed rails, thereby eliminating the need for expensive expansion joints at the switch. In a preferred embodiment, interlocking point shoes are also employed so as to hold the butt ends in vertical and horizontal register and transmit a signal to the trailing side rail of the impending approach of a load from the approach side rail, thereby reducing batter on the trailing side rail.

Abstract: There is disclosed a new process for the conversion of the organic components of sludge, particularly sewage sludge, to produce useful, storable, energy-containing oil products, apparatus for carrying out the process and a control process for optimisation of the process temperature. The sludge preferably is mechanically dewatered to about 20-25% solids by weight and thermally dried to about 90% solids by weight. The resultant material is comminuted and heated in the apparatus of the invention to at least 250°C in a heating zone in the absence of oxygen to generate a gaseous atmosphere containing volatiles; this atmosphere is then removed, scrubbed of H 2 S and NH 3 if required, and passed preferably in countercurrent flow in a heated reaction zone in intimate contact with the «devolatilized» sludge solids from the heating zone, again in the absence of oxygen, at a temperature of at least 280°C, resulting in catalysed vapour phase oii-producing reactions. The oil vapours are carried out by the gas flow and condensed. The preferred apparatus moves the sludge solids cocurrent with the heating zone atmosphere and countercurrent with the reaction zone atmosphere. In the reaction zone the conveyor not only moves the comminuted sludge along but lifts it and drops it through the gaseous atmosphere for the preferred intimate contact. Preferably the sludge is examined repeatedly by differential scanning calorimetry to generate a thermogram which has been found to reveal immediately the optimum temperature for operation of the reaction zone, and also the anticipated oil yield from the sludge.

Abstract: A process for treating cereal grains and particularly oats, to separate the endosperm from the remainder of the kernel without dry milling. The grains are soaked in an aqueous medium having a pH of 3.0 - 7.0 at a temperature in the range 40-70 °C for sufficient time to absorb at least an equal weight of the liquid medium. The condidions are such that the endosperm portion of the grain liquefies, as opposed to softens. The grain may be crushed in a variety of ways to split the husk and release the liquid endosperm contents which are then dispersed in water. The endosperm solids can be recovered from dispersion, following a screening step to separate the husks by drying to yield a substantially white, lower fiber whole endosperm flour product. Alternatively, the dispersion may be sedimented and/ or centrifuged to produce a wet solids fraction and a soluble fraction, each-of which can be subsequently recovered in dry form.

Abstract: A foundry mould binder component comprising at least one acid selected from the group consisting of glycolic acid, lactic acid, a-hydroxy butyric acid, valerolactic acid, a-hydroxy-caproic acid, tartronic acid, tartaric acid, malic acid, mucic acid, citric acid, gluconic acid, and glyceric acid, and a precipitant for the acid. The precipitant is for admixture with or contains the equivalent to at least 50% of the stoichiometric requirement of the total acid content of the binder component when the total acid content is in solution, said precipitant comprising at least one substance selected from the group consisting of cationic metal oxides and cationic metal oxide precursors, said precipitant being substantially non-fluxing with the foundry sand, and substantially nonreactive with respect to other mould components than the said acid, and substantially non-reactive with respect to metal which is to be cast in the mould. Taking one embodiment of the present invention comprising an aqueous solution of 50w/o citric acid and 3¾ w /o of a crushed limestone having a 96 w /o calcium carbonate content, and particles in a size range where 0 w /o is retained on a 140 United States Standard mesh screen and 20 w /o is retained on a 325 United States Standard mesh screen, then any other acid and precipitant mixture are selected to have a precipitation rate no faster than that said embodiment. The precipitant is preferably ground limestone, and the binder component may further include at least one humectant (e.g. sorbitol) admixed with the remainder to retard the loss of mould tensile strength during periods of low humidity.

Abstract: Human-like proinsulin gene analogs have been synthesized by a combination of chemical and enzymatic methods. A number of different human-like proinsulin gene analogs with altered C-chains have been designed and can be readily constructed as described. As a part of the strategy, an adaptor for trimming DNA has been used to recover the A-chain insulin gene with the desired sequence from a hybrid plasmid; a related adaptor for trimming DNA has been used to shorten the C-chain gene. The synthetic proinsulin gene has been joined to a replicable cloning vehicle and the hybrid DNA transferred to a host cell. The transformed host cells can be grown under selected conditions to yield the proinsulin analogs.

Abstract: This invention describes a pulsed plasma pinch x-ray source. In the device the initial plasma annulus (25, 27) is derived from an electrical gas discharge in a chamber (12) having constricted openings (16, 18) arranged on a circle. This low mass plasma annulus is imploded and pinched (34) by passing high current axially through said annulus. The hot and dense pinched plasma copiously emits x-rays and has the capability of being fired at high repetition rates. The device is simple for commercial applications, such as x-ray lithography.

Abstract: A breakwater comprised of an array of aligned perforated-wall (20,21) caissons (10) having a slab bottom (17) standing on a pervious rubble base (13) and anchored by its own weight incorporates exceptionally heavy ballasting (31) to ensure stability under attack by large waves, i.e. so that the ratio of maximum horizontal thrust force to net downward vertical force is below about 0.46. The immersed wall height is much reduced so that the slab bottom lies below mean sea level about 1.3 to 1.7 times the height of the greatest wave predicted, lessening costs of construction and siting. Efficient energy dissipation function is preserved by placement of augmenting mass below the height of the wave trough and by providing flow passages for jets directed by front wall ducts, avoiding increase of reflection coefficient. The mass may be a pervious rubble store, or a lower-grade concrete cast about horizontal duct pipes extending into or wholly through the chamber, or may be metal slabs supported on racks, or may be apertured fairing bodies carried on the front wall. Double-sided breakwaters on coasts where wave incidence occurs only at high tides incorporate a large proportion of ballast mass; when oriented as groins to protect a river mouth, the porting of an intermediate wall allows sands to migrate freely through without accretion. The rubble base comprises a core of gravel capped by larger rubble.
