Abstract: A solid state motion analysis system (10) stores images of an event at a fast frame rate and plays back the images at a slower frame rate to facilitate analysis of the event. The motion analysis system (10) includes a solid state imager (12) which is selectively operable at different frame rates and further includes a solid state memory (32) for storing a plurality of image frames. A video trigger circuit (46) includes a comparison circuit to compare selected images produced by the imager (12) to determine a change in the value of an image characteristic between the images. When a change is determined, the video trigger circuit (46) produces a trigger signal to alter the mode of operation of the motion analysis system (10). Thus, storage of image frames may be started or stopped when a difference in luminance or color occurs between successive image frames, such difference indicating a change in the event.

Abstract: The invention provides a chemical reaction system and an apparatus exemplified by a photographic process wherein a photo-sensitive paper substrate (5) is passed through a developing solution (2) contained in a main tank (1) and then through a replenisher tank (11). Replenisher tank (11) in turn overflows back into the solution (2). This reduces the presence of unwanted by-products on the substrate. On leaving the replenishing solution the paper passes straight into an amplification tank (17), and thence into a conventional bleach-fix or fixing solution (4).

Abstract: A web-spool (40) for a cartridge (10) comprises a cylindrical core (44) having an outer periphery at each end thereof with at least one core lug (48) and an annular ring (52) extending radially outward from each periphery in axially spaced relation to form a core peripheral groove (54) therebetween at each core end. The annular rings (52, 52) at both core ends have respective inner tapered surfaces (56, 56) that face each other to initially guide a web (42) being wound onto the core (44), and also to provide clearance between the wound web edges and adjacent core flanges (46, 46), to thereby accommodate any web telescoping and thus permit the flanges (46, 46) to be readily secured to the core ends without interfering with the web edges. Each flange (46) has an axially inner surface with an annular throat (64) extending axially outward therefrom for receiving the core lug(s) (48) and annular ring (52). Within the annular throat (64) is at least one radially inwardly extending flange lug (66) with recesses (70 and 71) at both sides thereof, the flange lug(s) (66) being adapted to nest within the core peripheral groove (54), and the recesses (70 and 71) being adapted to receive the core lug(s) (48) and the core ring (52) respectively, when a core end is inserted into the flange throat (64), the core (44) and flange (46) then being rotatably relative to each other to secure them (44 and 46) together. Complementary ratchet teeth (55 and 78) are provided on opposed mating surfaces (76 and 80) of the core (44) and flange (46), to permit relative rotation therebetween in one direction for securing the two (44 and 46) together, and to prevent relative rotation in the opposite direction and consequent unintended disassembly of those members (44 and 46).

Abstract: The invention relates to a punch-holder block for a perforating device and to a process for mounting punches (1) on said block. According to the invention, the block has a narrow groove (12) passing through the thickness of the block and extending along the entire length of the row of punches (1). The groove (12) is prolonged, at each end, perpendicular to the axis of alignment of the punches (1) so as to define a longitudinal beam (14) and two portions of transverse beams (15, 16). The groove (12) is arranged so that a deformation of the longitudinal beam (14) causes the two portions of transverse beams (15, 16) to move toward each other, thus blocking the punches (1). Application to the perforation of products in strip form.

Abstract: Copolymers are produced when 3,4-epoxy-1-butene (EpB) is copolymerized with maleic anhydride. The copolymerization is initiated by free radicals, and comprises both 1,2-propagation and 1,5-propagation of EpB. When an ether is used as the reaction solvent, the product is soluble, and essentially composed of (a) a monomer derived from maleic anhydride, and (b) two monomers derived from EpB. When the reaction solvent is a ketone, the polymer product is also soluble, and additionally contains (c) a moiety derived from a dioxolane formed in situ. When the reaction is conducted in the presence of a non polar (e.g., hydrocarbon or a halocarbon) solvent, or neat (i.e., in the absence of a solvent), the polymer product is insoluble in common organic solvents and contains (d) a symmetrical EpB dimer. This dimer apparently does not form, or is formed to only a very slight extent, when the polymerization is conducted in polar reaction solvents. Polymer products with a dioxolane moiety can be made by using preformed dioxolane in the polymerization mixture. Thus, this invention is not limited to in situ preparation of the dioxolane from a reaction mixture containing a ketone. Products of this invention can be cast as clear films and can also be used as reactive polymers.

Abstract: A beam position sensor for a beam scanner is disclosed for use in a laser printer. The printer comprises three diode lasers each of which emits at a different wavelength. The beams from the three lasers are combined by the use of dichroic plates to form one combined beam. The combined beam is scanned onto a receiving medium by a polygon. The beam position sensor of the present invention is adapted to sense the position of the polygon in order to provide a synchronizing signal which will insure that each raster line in the printer is started at the proper position. The beam position sensor includes a diode laser and optics for projecting a beam from the laser onto the polygon. The beam is reflected back from the polygon into a photodetector which effects the start of a new raster line at the appropriate time. In order to minimize the number of optical elements in the beam position sensor and to simplify the device, the diode laser and the photodetector are located along the same optical axis.

Abstract: A device for the electrolytic recovery of silver comprises a cylindrical electrolysis tank (10) made of plastic, against the inner wall surface (11c) of which rests an expendable cathode (30) which is formed into a hollow cylinder and consists of a sheet-type plastic carrier (31) to which a carbon sheet (32) has been applied by bonding. In the rim areas of the tank bottom (12) and the lower side of the removable top (14), projections (13, 15) are provided which extend into the tank (10) and have inclined portions (13a, 15a) extending away from the inner wall surface (11c) and behind which the lower rim portion (31a) and the upper rim portion (31b) of the carrier sheet (31) of the expendable cathode (30) are held, said carrier sheet extending further than the carbon sheet (32). At least one clamping bolt (40) of an electrically non conductive material is passed through a circular hole in the carbon sheet (32) and an associated larger circular hole in the carrier sheet (31) and is mounted and secured in a current-carrying contact bushing (36) arranged in tank wall (11). Owing to the different size of the circular holes, an annular area (32b) forming part of carbon sheet (32) is clamped between the head (40a) of clamping bolt (40) and the end face (36b) of contact bushing (36), which is located in the area of the inner wall surface (11c), and the cathode (30) is thus contacted and additionally held on the inner wall surface (11c). When the clamping bolt (40) is removed in the direction of the arrow, head (40a), which is shaped like a truncated cone, can be easily separated from the silver layer (52) deposited on the cathode.
