Title: Improvements in or relating to punching machines
IPC: B21D28/00
Filed: 1941-12-02
Abstract: 554,469. Punching. AMERICAN CHAIN & CABLE CO., Inc. Dec. 2, 1941, No. 15529. Convention date, Feb. 27. [Class 83 (iv)] [Also in Group XXIV] Punching machines, particularly nibblers, have the punch driven by a compound eccentric shaft providing means for length of stroke adjustment, the connection to the punch being such as to permit variation in stroke position. A gag facilitates work or punch adjustment. The punch 14 works through a presser foot 47 and is held in a chuck in a cylindrical member 15 guided by a slot 23 and pin 24 and connected by a screwed rod 34 with hand wheel 35 to a polygonal head 30 having a transverse slot for a die block 40 reciprocated by an eccentric 43. A gag 37 is interposed between a collar 36, on the rod, and the head 30. The eccentric is carried by a shaft 52 rotating in eccentric bearings in a divided shaft 54, 50 connected by bolts in spacing lugs 72. A disc 56 keyed to the shaft 52 has a series of holes to receive a pin 75 whereby the effective eccentricity may be varied. The disc has radial holes in its periphery for a tommy bar for use in effecting the adjustment in co-operation with a hand wheel 73 on the shaft 50. U.S.A. Specification 1,646,851 is referred to.

Abstract: 446,710. Coating threads by extrusion. LEMOINE, H. G., La BuissonniÞre, Perrierssur-Andelle, France. May 28, 1935, No. 15541. Convention date, May 28, 1934. [Class 87 (ii)] Apparatus for coating flexible threads of very small section with synthetic resin &c. comprises an extrusion nozzle or draw plate consisting of two jaws, each provided with one half of the orifice of the nozzle, and a conical or other device for closing the jaws so that they make proper contact with one another, with coincidence of the axes of the semiorifices. The two jaws 1, Fig. 1, each have an internal semi-conical recess 2 terminating at the upper face in a moulding orifice 3 having a sharp edge. The jaws engage in a conical seating 4 in a container 5 for the coating material. They tend to separate under the action of two springs 7 in borings 6, but are normally jammed together in their seating by a screw cap 8. The thread is inserted when the jaws are open. The lower end of the container is provided with a similar draw plate parallel to that shown, and having an orifice equal in diameter to the stretched or twisted thread so as to be closed completely by it as it is drawn upwardly through the container. The coating may comprise successively superposed layers obtained by passing the thread through a series of draw plates having calibrated orifices of progressively increasing diameter. In the modification shown in Fig. 4, the jaws 10 are of dove-tailed section and engage in slides 11 in the container 12, springs 14 tending to separate them. Their extremities rest on a conical seating 13<a> in a ring 13 screwed on the container 12, and the orifice 15 forms the top of an interior conical recess 16.

Abstract: 129,270. Aktiebolaget Wigelius Motorer. June 28, 1918, [Convention date]. Void [Published under Sect. 91 of the Act]. Regulating; valve-gear. - An angularly adjustable cam, intended more particularly for the air or fuel valve, is so arranged that, on adjustment, the lift and duration of opening of the valve are altered, but the time of opening, and preferably also the movement of the valve during the earlier part of the opening period, are unaltered. For this purpose, the cam 3 is mounted on feathers 4 on an eccentric 2 keyed to the shaft 1, and the cam is adjusted about the centre of the eccentric by sliding the eccentric along the shaft. The part of the cam-surface which effects the initial movement of the valve is an arc of a circle struck from the centre of the eccentric. Other shapes of cam may be used, and the eccentric may also be adjustable on threads on the shaft. The cam acts on the valve through a rocking lever 9.

Title: Improvements in the treatment of argentiferous lead-zinc sulphide ores
IPC: C22B3/06
Filed: 1921-06-08
Abstract: In the treatment of lead-zinc ores, and concentrates by the acid brine process in which a preliminary treating is effected, as described in Specification 151,698, the proportion of silver which dissolves with the lead is increased by removing the sulphuretted hydrogen when the lead is nearly all extracted, and continuing the digestion with the same or fresh brine (which may be more strongly acid) for a short time.  The zinc sulphide residue may be further leached with one of the solvents mentioned in Specification 151,698 to remove any remaining silver.  The removal of the sulphuretted hydrogen may be effected by adding a quantity of sulphur dioxide, which may be that evolved in the first stages of the treatment. Specification 127,641 also is referred to.

Suitable waxes include paraffin, beeswax and ozokerite and materials such as stearic acid, stearates and resins may be added. The sheets may be pre-coated with cellulose derivatives or polymerized vinyl compounds admixed with gums, resins, plasticizers, blown oils, dyes, pigments and waxes; a suitable lacquer comprising nitro-cellulose, dibutyl phthalate, blown rapeseed oil, ethyl acetate and benzene.  The wax is atomized in an apparatus comprising a heated trough 16 containing for example, paraffin, diluted if desired with toluol, a slowly rotating wheel 18 dipping into the trough 16 and a tangential nozzle 20 through which heated air is blown.  Large particles 21 are eliminated from the atomized wax by a baffle arrangement 23 and the residual air-borne particles are deposited on the material, which then passes through a heater 22, which may be provided with air-conditioning means to preserve the flexibility of the product, and a cooling device (not shown).  In a modification the atomizing chamber is separate from the depositing chamber and fans are used to circulate the air-borne particles.  Both sides of a sheet may be coated by passing it twice through the depositing chamber before fluxing.

Specific examples of sensitizers are C-cetyl betaine, N-cetyl betaine and N - (3 - cocoamidopropyl) betaine wherein " coco " refers to C 12-14  alkyl groups (derived from coconut oil). In the examples, latices of polychloroprene and styrene/butadiene copolymers, are used. Some or all of the organic liquid may be added to the sensitized latex before addition of the acid, examples of the latter being HCl, H 2 SO 4  and HNO 3 . The choice of organic liquid obviously depends on the polymer, but in the examples heptane, and a hexane/toluene mixture are used.
