Abstract: 1,163,704. Stamping; dividing. ZENTRALINSTITUT FœR FERTIGUNGSTECHNIK DES MASCHINENBAUES. 8 Feb., 1968, No. 6249/68. Headings B3Q and B3W. In a method of forming and/or shearing by discharging a spark or exploding foil or wire, pressure is transmitted through a solid medium 3, e.g. paraffin wax, grease or synthetic resin. For re-forming flat work, apparatus for performing the method comprises foil or wire (7, 8), Figs. 3 and 4 (not shown), embedded in a plate (3) of the transmitting medium. For expanding and/or cutting tubes, the vaporizable wire 5, Fig. 2, is embedded in a cylinder 3 of the solid medium. As used for constricting a tube, the wire 10, Fig. 6, or foil (9), Fig. 8 (not shown), is embedded in a hollow cylinder 3 of the medium. When the wire 10 is in the form of a coil, an electromagnetic forming force is also present.

Title: Improvements in folding push cars
IPC: B62B7/10
Filed: 1921-02-25
Abstract: 177,959. Thomas, G. Feb. 25, 1921. Folding vehicles.-A folding push-car comprises a bridge-shaped frame, wheels foldable into the frame and mounted on axle brackets which rotate on upright pivots therein, and side-members pivoted thereon and supporting a folding back, arms, and seat forming a wheeled chair when opened out and an enclosure for the wheels when folded. The axles 3, Figs. 1 and 2, of the wheels 4 are bent upwards and pivoted to depending members 2 of the bridge-shaped frame 1 so that the wheelscan fold into the frame or be opened out to project fore and aft when they are locked by the engagement of cams or catches 7 with the superstructure. Side-members 8, 9 pivoted at 10, 11 respectively to each member 2 extend upwards. in divergent directions and support a wooden seat-frame 23 and arms 17 which are pivoted at 24 and 18 respectively to the members 9. A lug 25 on the seat-frame 23 extends over a projection 27 on each member 8 and is clamped' thereto by a thumb-screw 26 or other means. This arrangement draws the members 8, 9 together and against a stop 30 on the member 2 to secure the whole structure rigidly, the free ends of the arms 17 then engaging between projections 20, 21 on members 12 pivoted to the upper ends of the members 8. A transverse bar 13, serving as a propelling handle, and rods 14,. 15, which support the seat-back 16, interconnect the members 12. The members 17 are of channel cross-section to accommodate elastic connections 29 which link together the members 9, 12' and guide the arms 17 between the projections- 20, 21. To fold the car, the seat is freed from the member 8, the members 12, 17 fold on to the members 8, 9 which are turned down about their pivots, the wheels 4 and a foot-rest 31 folding within the frame 1 and the seat 22 and seatback 16 covering the front and rear of the frame so as to present the appearance of an attachÚ case as shown in Fig. 4. Springs may assist to unfold the wheels or they may be connected by gearing to the other folding 'members.

Title: Cospun heather yarns
IPC: D01F6/60
Filed: 1975-02-14
Abstract: 1476545 Dyeing leather yarns E I DU PONT DE NEMOURS & CO 14 Feb 1975 [15 Feb 1974] 6399/75 Heading D1B [Also in Division B4] A leather yarn comprises a dyed assembly of two types of filaments. One is a sheathcore composite filament in which the sheath and the core are made from different thermoplastic polymers and the other is a homofilament composed of the same polymer as the core. The yarn is produced by the simultaneous extrusion of the two polymers in an appropriate fashion (see B5 abridgment). The two polymers are chosen so that one class of dye will dye one but not the other and so that a second class of dye will dye both. It is preferred to use, as the first class of dyes, acidic or basic dyes and disperse dyes as the second. It is also preferred to use as the sheath polymer one which is not dyeable by the acidic or basic dyes chosen, but to use a core polymer that is. Both polymers should respond to the disperse dye. In such a case, the sheath protects the core from the acidic or basic dye, which thus dyes the homofilaments only, whereas the disperse dye, to which the sheath is susceptible, penetrates and dyes both the sheath and the core, thus avoiding ring-dyeing effects in the conjugate filament and so providing a yarn composed of filaments having two different colours. In Examples I and II the core/homofilament polymer is a copolymer of ethylene terephthalate and 5-(sodium sulpho) isophthalate and the sheath polymer is polyethylene terephthalate. Three dye-bath compositions are given, all containing a basic dye to which the core polymer, but not the sheath, is susceptible. In Example III, the core/homofilament polymer is poly (hexamethylene adipamide) and the sheath is poly (ethylene terephthalate). The filaments are boiled in one of two dyebath compositions, C.I. ABL107 being used as the dye selective for the core polymer in both.

Title: Improvements in or relating to the production of moistureproof films
Inventor: BERRY WILLIAM
IPC: C08J7/048
Filed: 1953-03-09
Abstract: 744,677. Moisture-proof hydrophilic films. BRITISH CELLOPHANE, Ltd. March 4, 1954 [March 9, 1953], No. 6474/53. Addition to 677,926. Class 140. The process of the parent Specification is modified by using an aqueous dispersion of a vinylidene chloride polymer or copolymer, the aqueous phase of which has a pH between 4 and 14, preferably between 4 and 9. In Specification 677,926 moisture-proof film is produced by applying to water-sensitive, non-fibrous organic base film a partially condensed hydrophilic ureaformaldehyde resin from a neutral (pH 5-8) aqueous dispersion, drying the film with curing the applied resin to the hydrophobic state, and then, while the applied resin is still in the hydrophilic state, applying to the dried film an acidic (pH 1-4) aqueous dispersion of vinylidene chloride polymer or copolymer, and finally heating to evaporate the water, to cure the applied resin to the hydrophobic state, and to consolidate the surface coating. The film may be regenerated cellulose, and the electric charge on the urea-formaldehyde colloidal particles should be opposite to that developed by the film in contact with water. The proportions of urea to formaldehyde may be 1 mol. to 2-3 mols. Vinylidene chloride may be copolymerized with acrylonitrile, vinyl chloride, vinyl acetate, styrene, ethyl acrylate, methyl methacrylate, and n-butyl methacrylate or mixtures thereof. Where vinylidene chloride is copolymerized with methyl methacrylate, acrylonitrile, or ethyl acrylate, or mixtures thereof, an acidic compound namely itaconic or citraconic acid or anhydride or mesaconic acid may be included. The vinylidene chloride dispersion may be brought within the required pH range by addition of sodium bicarbonate, ammonia, or caustic soda, and may be applied to the film in a layer of such thinness that the water is wholly absorbed by the film. Specifications 700,619 and 703,010 also are referred to.

Abstract: 723,138. Automatic firearms. GEVARM. March 17, 1952 [April 17, 1951], No. 6886/52. Class 119. The sear 15 for holding the breech-block 3 in the cocked position has an elongated slot for engaging a pin 16, so that it rocks about and slides on the pin, the rocking movement being limited by means such as a pin 17 engaging a further slot in the sear. The sear is urged towards the breech-block by a spring 20 and has a projection 15<SP>1</SP> for engaging a projection 133 on the trigger 13. In use, operation of the trigger first causes the sear to slide away from the breech-block and subsequently to rock until the projections disengage, the spring then serving to return the sear to engage the breechblock when the latter returns to its cocked position. The breech-block shown has a cylindrical extension 32 of small diameter sliding in a box 21 of the breech casing 2 and serving to strike the base of a cartridge in the breech chamber 1<SP>1</SP>. The sear and trigger are mounted in a carrier 10 which is secured by a screw 11 to the breech casing and which is fitted with a pivoted catch 9 serving to hold in place a box magazine 8. The trigger on being pulled rocks about an adjustable screw 22 when this encounters the lower face of the casing 2, such rocking being permitted by a slot in the trigger engaging the pivot pin. The pin 17 shown may be rotated from the position shown, in which position the sear may slide and rock as above described for single shot firing, to a position in which it engages the side walls of the slot and thus permits sliding only. The trigger in this case does not slip off the sear and firing is continuous. The spent cartridge cases are ejected through a flared opening 25 by the force of the gases developed on firing.
