Abstract: 409,327. Shirts and collars. SHEPHERD, T. L., 18, Marlborough Street, and SHEPHERD'S SHIRTS, Ltd., 169, Western Road, both in Brighton. July 25, 1932, Nos. 20976, 21823, and 32072. [Class 141.] The neckband of a shirt and a collar are maintained in their proper position during wear without the aid of a back collar stud by the provision of interengaging ridges of resilient material such as indiarubber. The ridges may be continuous or may be interrupted, and may take the forms shown in Fig. 5 and Fig. 6, in which the ridge on the collar is larger than that on the neckband so as to overlie it and increase the security against detachment. In the construction shown in Fig. 5, rubber or like cords c, g, which are usually of circular cross section, are enclosed in sheaths d, k respectively, which sheaths may be of fabric or other material. The sheaths may be of resilient material enclosing hard cores. In Fig. 6 is shown a construction with the engaging surfaces of the ridges in an inclined direction to increase the security. Other constructions are described in which the ridges are of various shapes in cross section and in which the core is a built up one of multiple strands of rubber.

Title: Improvements in or relating to a process for treating the residues from the manufacture of copper alloys
IPC: C22B7/04
Filed: 1958-07-01
Abstract: Scum slags from molten baths of copper-zinc alloys are treated with sulphuric acid to dissolve zinc and impurities and to leave a copper-containing residue.  The solution is filtered and treated to remove impurities, copper being precipitated by contact with zinc waste, iron being oxidised to the ferric state by hydrogen peroxide or permanganate and precipitated by addition of lime or zinc oxide or by the action of chlorine or hypochlorite. Manganese is precipitated by addition of potassium permanganate and cadmium and nickel by adding zinc powder.  The resulting solution contains substantially pure zinc sulphate.ALSO:Scum slag from the manufacture of zinc-containing copper alloys is subjected to wet treatment with sulphuric acid to extract from it zinc and other impurities, the insoluble residue from this treatment being subjected to further tratment to recover the copper in a furnace such as a cupola or electric furnace.

Title: Improvements in a dough beater
IPC: A21C1/14
Filed: 1962-06-01
Abstract: 950,301. Dough dividers. KOOPERATIVA FORBUNDET EKONOMISK FORENING. June 1, 1962 [June 1, 1961], No. 21333/62. Heading B5A. [Also in Divisions B1, B8 and F1] A dough divider comprises a sector of a cylinder 9 which is given a motion of rotary reciprocation to occlude alternately a dough inlet 27 and outlet 28 in a housing 26. The dough is pumped by a flexible diaphragm 30 alternately extended and retracted, in synchronism with the movements of the member 29, by oil contained in the space between the diaphragm 30 and a piston 33 actuated with adjustable stroke by the hydraulic cylinder 32. The dough is supplied from a dough beater (see Fig. 1, not shown, and Division B1 and may be discharged as lumps (see Fig. 1, not shown); into moulds; or, as shown, to a nozzle 58 for forming it into a shape suitable for tin loaves. The dough strand is cut by a wire 59a stretched across a yoke 59 and the dough slabs 36a, 36b pass on to an endless belt conveyer 57 off which they are pushed sideways on to another belt conveyer 80 by a pneumatic ram actuated by a photo-electric cell 82. The rate of operation of the divider is controlled by a variator 44 through a double-acting pneumatic cylinder 39 which is pneumatically synchronized with the cutter 59a, a cylinder 51 which gives an intermittent forward motion to the conveyer 57, and a cylinder 79 which gives a second intermittent forward motion to the conveyer 57 to space the dough slabs from each other. The pneumatic cylinder 51 is combined with an hydraulic cylinder 53 which is in turn hydraulically synchronized with the dough pumping cam 32. The beater and divider form a unit balanced about a pivot; the divider is normally driven at a greater capacity than the beater so that when the discharge chamber of the beater is empty the apparatus tilts slightly to actuate a switch which arrests the divider until more dough has passed through the heater and, accumulating in its discharge chamber, rocks the apparatus back again.
