Patent GB-752448-A (GB)
Title: Improvements relating to projectiles
Inventor: PHILIP SVEN EMIL
IPC: B21D51/54
Filed: 1954-12-13
Abstract: 752,448. Ammunition projectiles. AKTIEBOLAGET BOFORS. Dec. 13, 1954, No. 35990/54. Class 9(1) [Also in Group XXII] A non-explosive projectile having an outer case, e.g. of steel, enclosing a core of more brittle material, e.g..tungsten carbide, has the outer case so arranged around the core that the core is subjected to longitudinal and/or lateral pressure by the case. The projectile.is formed in an annular die 1 whose internal face is flared towards the top to receive the flared end of the case 2. A cushion 3, e.g. of aluminium, is inserted into the case, before introducing the core 4. and a closure member 6 by means of a presser 5. The member 6 has a chamfered edge and a coaxial cylindrical projection 7 which enters the presser 5. Downward movement of the presser is continued, subjecting the case to tension and forcing the flared end inwards to engage the member 6, the finished projectile being received by a conveyer belt (not shown) as it leaves the die. Before assembly, the case may have an inside diameter less than the diameter of the core along the greater part of its length. A preheated case may be used which shrinks on cooling after assembly. Specification 752,067 is referred to.

Abstract: 1,192,006. Measuring pressure electrically; pressure gauges. ELLIOTT BROS. (LONDON) Ltd. Aug. 8, 1967 [Aug. 12, 1966], No. 36174/66. Headings G1L and G1N. Deflection of a pressure capsule 1 is communicated to a differential beam 5 by a link 4 causing the beam to pivot about its end 6 and communicate movement to a detector beam 10. This beam is pivoted by cross-springs 11 at its centre and carries the input member 14 of a transducer 15 by means of which a pressure representative signal is transmitted through an amplifier 16 to a servo motor 17 driving a pointer 18 over a scale 19. The servomotor also operates to provide feedback through a gear train 20 and links 21, 23 to restore the beams 5 and 10 to their undeflected positions, whereby the arrangement operates in a null mode. In accordance with the invention, the arrangement may be operated in a second mode by actuating a mechanical clamp 24 to lock the end 9 of beam 10 against movement. By clutch means (not shown) the servomotor 17 is also disconnected from gear train 20. In this mode of operation, the feedback is inoperative and deflection of beam 5 takes place about end 7 to transmit movement to pointer 18 from the other end by way of links 21, 23 and gear train 20. According to a modification, detector beam 10 may be dispensed with and the transducer 15 and clamp 24 transferred to the end 7 of beam 5. The pick-off portion of transducer 15 may be controlled in position for the purpose of introducing corrections into the system. A second embodiment, Figs. 2 and 3 (not shown), employs two pressure capsules controlling a common detector beam. The arrangement is generally similar to Fig. 1, but includes full details of the arrangement for actuating the mechanical clamp Fig. 4 (not shown) and unclutching the servomotor 17 from the gear train. Details are also given of the arrangement for positioning the transducer to introduce corrections. Reference is made (without giving specific details) to a modification whereby this arrangement measures the difference of pressure of the two capsules.

Title: Improvements in and relating to the manufacture of graft synthetic rubber products
Inventor: DAVENPORT NOEL ERNEST
IPC: C08F279/02
Filed: 1958-11-14
Abstract: Graft synthetic rubber products are made by mixing (A) an emulsion of a rubbery copolymer of (i) butadiene (60 to 90 parts) (40 to 10 parts) or (ii) butadiene (60 to 90 parts) acrylonitrile (5 to 35 parts) and styrene (5 to 35 parts), and (B) a monomeric material selected from methyl methacrylate, styrene or a mixture of styrene and methyl methacrylate or acry-lonitrile, the proportion of monomer (B) not exceeding 80% of the weight of copolymer (A), the mixture so-obtained is stirred and/or allowed to stand so as to bring about swelling of the rubber by the monomer, and there is then introduced a catalyst which brings about the polymerization of the monomer, the amount of the monomer (B) being such that the butadiene content of the final composition is at least 45% by weight, and the amount and nature of the catalyst and the temperature at which the process is conducted are chosen so as to produce a graft copolymer which is cross-linked so that it has a gel content between 60 and 90% by weight of the product.  In a modification of the process there is used a rubbery copolymer (A) which is first cross-linked in latex form before graft polymerization with the monomer (B).  As polymerization catalysts there may be used potassium persulphate and a mixture of cumene hydroperoxide and tetraethylene pentamine.  The styrene of copolymer (A) and monomer (B) is preferably styrene itself, but may also be a styrene derivative, e.g. vinyl toluene, alpha-methyl styrene, chlorostyrenes and divinyl benzene.  The resulting graft copolymers may be used as processing aids for rubbers and in blends with styrene-acrylonitrile copolymers.

The whey is removed from the curds in a sieve cylinder in which the curds are also partly compressed, after which they are finally compressed in a mould. In the form shown in Fig. 2, curds are fed directly from a vat or from a collecting tank to an inlet opening 3 in a cylinder 1 with a double plunger 2 which feeds a measured quantity of curd through the opening 4 to one of a number of sieve cylinders 6 carried on a turntable 5. The cylinders 6 move over an arcuate plate 8 which closes them at the bottom. The draining whey is collected in a trough 7. Any residue is expelled by a plunger 9. Each cylinder then moves over a hole in the plate 8 through which the curd is expelled by a plunger 10 into one of a succession of moulds 12 brought into position by a turntable 11. In the form shown in Fig. 3, each sieve cylinder 22 has a plunger 23 controlled by an air-operated cylinder 25. Each cylinder passes, in turn, over an air-operated valve 29, in a plate 21, controlling the supply of curd from a pipe 30. The supply of curd lifts the plunger 23, the weight of which may be counterbalanced by an air supply to the cylinder 25, until it operates a switch 28. The whey drains into a channel 31. The cylinders are discharged into moulds as in the arrangement of Fig. 2.
