Abstract: A process for making a dispersion-based asbestos strand for later twisting to form a yarn comprises (a) forming an elongate continuous stream from an aqueous coagulable dispersion comprised of asbestos fibres, water and dispersion-forming chemicals; (b) coagulating said dispersion in said stream to form a self-sustaining asbestos fibre strand containing coagulated dispersion-forming chemicals together with uncoagulated residues thereof and water; (c) while said strand is in an untwisted state removing substantially the whole of the coagulated dispersion-forming chemicals and said uncoagulated residues thereof; and (d) adjusting the water content of the strand to provide an untwisted strand formed substantially wholly of said asbestos fibres and containing not more than 20% by weight of water.

Abstract: Stamping means in a single stroke initially passes upwardly through a pool of coating material to collect coating stuff on the face of the die element, then through a restricted opening formed integral with the coating material reservoir to remove excess coating stuff from the periphery of the die and finally into functional engagement with a substrate to simultaneously deform and coat the substrate.

Abstract: This disclosure relates to a machine for clearing bulk material from a bin table by moving therealong a movable support carrying a pivotally mounted rotatable clearing wheel including a first drive mechanism for moving the movable support and a second drive mechanism for rotating the clearing wheel and a control mechanism responsive to operational conditions of the second drive mechanism for controlling the operation of the first drive mechanism whereby the rotational speed of the clearing wheel may be increased or decreased as might be the speed of the movable support in dependence upon the resistance of the bulk material being offered to the clearing wheel during the rotation of the latter.

Abstract: For use with frozen food products, such as dough, having a substantially larger bulk volume at an elevated temperature than when frozen, a container is erected from a container blank having a plurality of fold lines and being so arranged that, when the blank is folded along a first selection of said fold lines in a first manner, it defines a container having a bulk capacity of a first predetermined volume and, when folded along a second selection of said fold lines in a second manner, it defines an open, tray-like container having a bulk capacity of a second predetermined volume larger than the said first volume, and a base area different from the base area when the blank is folded in said first manner. The ratio of the said volumes is preferably 1:2. The blank may be glazed or lined (e.g. with aluminum foil) on at least one side thereof.

Abstract: A method of operating a pyroelectric camera tube having a normally provided electron beam emitting cathode and control grid G.sub.1 controlling the electron beam, and a gas in the interior space of the tube by applying positively-going pulses to the grid G.sub.1 during the period of the normally applied line blanking pulses. A circuit for producing the positively-going pulses is also disclosed which have the effect of increasing the target pedestal potential.

Abstract: This disclosure is directed to a mold particularly adapted for applying pre-cured tread rubber to a tire, the mold including a pair of generally annular mold bodies which collectively define a chamber adapted to receive a tire, the mold bodies being capable of relative axial adjustment whereby axial dimensions of the chamber may be varied to accomodate tires of different widths, an annular band for locking the mold bodies to each other at a particular position of axial relative adjustment, and axially shiftable means for maintaining the mold bodies at a desired position of relative axial adjustments.Preferably an annular resilient rubber or like envelope surrounds the tire as well as its sidewalls to prevent steam or an equivalent heating medium from permeating between the tire and the pre-cured rubber glue thereto.

Abstract: A cable or rope clamp comprising a ferrule or sleeve having an oval body portion and a frusto-conical end portion, the wall of said end portion having an outer surface which, at the junction with said body portion, has a sharp concave part to locate said ferrule in compression dies, said wall of said end portion being generally of concavo concave shape.

Abstract: A process of packaging a solid gas evolving product by filling a plurality of pouches with the product, partially sealing each pouch mouth by a heat seal to leave a relatively small tortuous passage for the escape of gas from the product, transferring the pouches to a storage chamber containing oxygen at atmospheric conditions of temperature and pressure, storing the filled pouches in the chamber until substantially all of the gas capable of evolving from the product has evacuated the pouches, removing the pouches from the storage chamber and thereafter hermetically sealing the pouches against oxygen containing atmosphere by completely sealing each tortuous passage.
