    Abstract: An indirect extrusion process, and apparatus therefor, for producing an extrusion product from a hot metal billet. A press container is mounted to be substantially axially stationary during extrusion of a billet. A hot billet, a die and a pressure disc are located into the axial throughbore of the container so that the billet is sandwiched between the die and pressure disc, with the pressure disc having a maximum outer diameter between opposite radial faces which is slightly less than the diameter of the axial throughbore to define a diametrical clearance between the pressure disc and the press container. A bolster is located adjacent the pressure disc and is axially fixed to substantially prevent axial movement of the pressure disc in a direction toward the bolster during extrusion. The bolster exerts a relatively insigificant axial force against the container. An elongated stem having an axial passage is moved into the throughbore of the container to press the die toward the bolster, causing the billet to be extruded through the die to create an extrusion product which exits the container through the axial passage in the stem, while extrusion of the billet through the diametrical clearance between the pressure disc and the container is substantially avoided.

    Abstract: 1,175,378. Laminates. LIMEHOUSE PAPER MILLS Ltd., L. HOAD, S. C. CRONAN, and R. H. NELSON. 13 Feb., 1967, No. 6687/67. Addition to 1,015,746. Heading B5N. [Also in Division B2] The Specification describes the same paving strip as Specification 1,015,746, but wherein the binder comprises a bituminous material other than coal tar. The petroleum binder may be a straight-run, a cut-back, a blown or a coloured bitumen or asphalt, e.g. Lake Asphalt mixed with a diluent. A release agent comprising a detergent with or without soap may be incorporated in the strip to lessen the adhesion between the binder and the undercover. A release agent may also be applied to the undercover by screeding, rolling or spraying before the bitumen impregnated backing is applied thereto.

    Abstract: 119,433. Stewart, C. M. July 9, 1918. Addition to 107,278. Cleaning internally, non-rotary appliances for.- Relates to improvements in the means for sweeping chimneys described in the parent Specification in which a brush is carried by an endless rope passing over a pulley carried by a bracket secured to the chimney top. The band encircling the chimney is formed in two parts L, M and its size is adjusted by varying 'the position of the bolt N. The bracket is also formed in two parts A, B secured to the band as shown and secured together in an adjustable manner by the bolt H which also supports the pulley. To prevent the endless rope twisting, an 8-shaped guide W is fitted in the chimney.
