Patent GB-580617-A (GB)
Title: Process for reclaiming waste rubber
IPC: C08J11/18
Filed: 1944-07-10
Abstract: Waste rubber is reclaimed by subjecting it at a temperature between 180 DEG  and 210 DEG C. and under elevated pressure to the action of a mixture of saturated steam and the gases or vapours of one or more organic substances which in the liquid or gaseous state have a swelling action on raw or vulcanized rubber, direct contact of the rubber with said organic substances in the liquid state being prevented before and during such treatment.  The process may be carried out in a pressure vessel fitted with grids.  Oxidising conditions are avoided either by heating the waste rubber, organic substance and water in the pressure vessel with the outlet valve open till all the air has been expelled or by adding the organic substance after the air has been removed, or by replacing the air by an inert gas such as nitrogen or carbon dioxide. Suitable organic substances include aliphatic, aromatic or hydroaromatic hydrocarbons such as butane, petroleum ether, benzine, kerosene, benzene, xylene, naphthalene, cyclohexane, limonene, decahydronaphthalene, heterocyclic compounds such as picolinc thiophane and furan, substituted products of hydrocarbon including alcohols such as butyl alcohol, carbonyl compounds such as cyclohexanone, ethers such as anisole, and halogenides such as monobrombenzene.  Specification 719/10, [Class 70], is referred to.

Filed: 1948-05-14
Abstract: 655,201. Instruments for deaf persons. STEVENS, A. H. (Patent Management, Inc.). May 14, 1948, No. 13275. [Class 40 (iv)] In a bone conducting receiver the direction of motion of the contact member is substantially at right angles to that of the operating member. As shown in Fig. 1, the case 10 of the receiver is open at the front and is normally closed by a closure 15 which supports the mechanism. A supporting plate 24 rests against the back wall 11 and is attached to the closure by two legs 16 having feet 17, 18. The feet 17 are screwed to the plate 24 and the feet 18 are bolted to the closure, the bolts passing through pads 21. The plate 24 is screwed to the back 11, and the magnet 26 to the plate 24, a spacer 31 serving to centre it in the case 10. Mounted on the plate 24 is a block 34 supporting a vibrating reed 35 which carries the armature 36. The free end of the reed 35 carries a mounting 37 attached to one end of a leaf-spring 38, the other end of which is screwed to a pad 39 on the closure 15. The reed 35 is thus constrained to vibrate towards and away from the poles 33 under control of varying currents in the magnet windings. Attached to the mounting 37 is a spindle 42 guided for longitudinal movement by a bushing 43 in a boss 44 formed on the closure 15, and carrying at its outer end the contact member 45. Pressure applied to the surface 46 of the contact member 45 is end-wise against the reed 35 and does not effect movement thereof. However, movement of the armature 36 in response to incoming signals results in movement of the contact member 45 normal to its contact surface 46. In a modification, Fig. 3 (not shown), another magnet with its associated reed and armature is mounted opposite the first and both reeds drive the contact member, the leaf-spring 38 being dispensed with.
