Title: Gun loading device
IPC: F41A9/42
Filed: 1937-05-03
Abstract: 480,562. Gun - loading appliances. RHEINMETALL - BORSIG AKT. - GES., and WANINGER, C. May 3, 1937, No. 12566. [Class 92 (i)] Ammunition is inserted in the gun chamber by one or more rolling surfaces located in the breech-loading aperture of the gun barrel and moved by a driving device so as to engage directly by rolling contact either with the ammunition or with a ram-rod. In the simple form shown in Fig. 1, rollers c<1>, c<2> are mounted in the loading trough of the breechblock b, and the roller c<1> is driven so as to seize the ammunition d and thrust it forward into the chamber a<1>. The rollers may rotate about horizontal, vertical, or inclined axles, and one or more of the rollers exert a yielding pressure on the ammunition. The peripheral surfaces of the rollers may have suckers or other recesses to increase adhesion. Fig. 6 shows a recoiling gun barrel a fitted with a power-operated roller device c<1> mounted on a frame g sus. pended from a lever h pivoted to the breech, the device occupying its operative position with the breech open. Fig. 9 shows the device occupying a raised inoperative position with the breech closed. The non-driven roller c<2> is mounted in the loading trough b<1> of the wedge breech-block b. The lever h is connected to a spring accumulator i pivoted to the gun cradle at i<1> and the roller c<1> is driven from a motor k on the cradle through a telescopic shaft c<8> and gearing carried by a link c<5> which serves to suspend the roller c<1> from the lever h. The spring accumulator comprises a prestressed spring i<5> mounted in a casing i<6> and engaged by a rod i<2> hinged to the cradle at i<1>, and a second prestressed spring i<8> operating between the casing i<6> and a casing i<7> hinged at h<2> to the cranked lever h. A spring-controlled latch i<9> controlled by a projection h<3> on the lever h serves to lock the casings i<6>, i<7> together, thereby causing the spring i<5> to lower the roller c<1> into operative position, and the release of the latch enabling the spring is to raise the roller to inoperative position. These movements are controlled by an ammunition feeler n acting through a three-armed catch m<1>, m<2>, m<3> on a spring-controlled cylinder l surrounding the link c<5>. With the parts positioned as shown in Fig. 6, the rim of a cartridge when loaded raises the feeler n and releases the catch m<2> to permit the roller to rise and the breech-block to close. On firing, the recoil of the barrel loads the springs i<8>, i<5> and the roller c<1> follows the breech-block as it opens until the cylinder l engages the catch m<1> to hold the roller clear of the ejected empty case. When the feeler n ceases to bear on the case, the catch m<1> is released and the roller c<1> then assumes the operative position shown in Fig. 6.

Title: Improvements in or relating to a pile lifting device for pneumatic sheet feeders
Inventor: SCHWEBEL ADOLF
IPC: B65H1/30
Filed: 1958-04-30
Abstract: 885,099. Feeding sheets. MABEG MASCHINENBAU G.m.b.H. April 30, 1958, No. 12737/61 Divided out of 885,098. Class 100(1) Pile tables. In apparatus for separating sheets from the top of a pile without interruption during pile replenishment, there are two separate pile lifting means for a main table and an auxiliary table, and a safety rail device is mounted on the lifting supports for the auxiliary table whereby the ascent of the fresh pile is bolted automatically when it presses up against the residual pile, so that the top of the residual pile cannot be forced up and damage the sheetseparating mechanism. Basically, the apparatus is substantially as described in Specification 885,098. When a new pile 17 is first introduced, it is placed on a main table 16 and raised by a main motor 3 and chains 13 until the top of the pile meets a limit switch 28, 29, whereupon the motor is cut out, and the pile step-by-step by a panel 4, driven from an independent source, acting on a ratchetwheel 6. The pawl 4 is controlled by a reciprocating pile feeler 47, a Bowden wire 50, and a pawl-lifting lever 5. When the pile has been depleted to the extent that the main pile table 16 has been raised above the level of the starting position of an auxiliary table 41 and its supports 39, 40, the table 41 is inserted by hand between the base of the residual pile (denoted 42) and the main table 16. A switch 38 is now depressed manually to close the circuit of a high-speed winding 44 of the auxiliary motor 43 which raises the supports 39, 40 through chains 24 and a chain drive 62, 63. The support 39 incorporates the safety rail device, which comprises a switch 52-56, Fig. 2, operated by a top rail 55 which is urged upwardly by a spring. When the rising supports 39, 40 take the weight of the depleted pile 42, the rail 55 is depressed, and the switch 52 is operated to stop the auxiliary motor 43. A lever 30 is hand-operated to raise the pawl 4, and a manual switch 46 is operated to bring into circuit a low-speed winding 45 of the motor 43. The pile feeler 47 now controls the motor 43 to raise the pile 42 step-by-step. The main pile table 16 is lowered by the motor 3 on depression of a switch 37, and the table is raised with the new pile 17 on operating the switch 38. Operation of a further switch 46 connects the safety rail switch 52-56, so that when the new pile comes up below the auxiliary table 41 and starts to lift it off its supports 39, 40, the load on the rail 55 is removed, the safety switch is opened, and the main motor 3 is stopped.

Abstract: A polymisable material comprises a polyallyl ester, e.g diallyl phthalate, as binder, and a filler of kaolin which has been dehydrated by calcining at 600-1200 DEG  C.  It is preferred that at least 65 per cent of the binder is the ester and at least 50 per cent of the filler the kaolin.  A polymerizable unsaturated alkyd resin may also be present in the binder.  The polyallyl ester may be partially polymerized as disclosed in U.S.A. Specifications 2,433,616 and 2,426,476.  The filler may also contain asbestos, preferably chrysotile asbestos, or it may also contain a cellulose filler, e.g. alpha cellulose, shredded paper, chopped cloth, cotton flock, cotton linters, purified wood fibres, cotton wool or regenerated cellulose coated with a thermosetting heterocyclic polyame-formaldehyde reaction product converted to its infusible state on the cellulose. The heterocyclic polyamine is a substance whose molecule has a plurality of NH2 groups, each connected to a carbon atom contained in a heterocyclic ring, the ring consisting of from five to six carbon and nitrogenatoms of which not more than three are nitrogen atoms, e.g. melamine. It is preferred that the cellulose filler constitutes not more than one-third of the total filler.  Moulding compositions may be produced by mixing a solution of the partially polymerized polyallyl ester in a solvent (acetone) with the filler and a catalyst (peroxides, persalts, peracids or ozonides) and heating to remove solvent and finally to polymerize the composition.
