Title: Improvements in or relating to land-mines
IPC: F42B23/00
Filed: 1962-04-26
Abstract: 1,005,388. Land-mines. INDUSTRIE-WERKE KARLSRUHE A.G. April 26, 1962 [April 27, 1961], No. 16069/62. Heading F3A. A land-mine which provides a safety period during which it cannot be detonated includes a release member, also acting as a pressure cover, which tilts over the surface of a hard elastic inner member disposed between the cover and the mine casing, to detonate the mine when an off-centre loading is applied, but which merely presses against the inner member without detonating the mine when subjected to the action of perpendicularly acting detonation waves. An outer, more flexible elastic member, disposed between the cover and the casing serves to protect the inner parts. In Fig. 1, an explosive charge 2 is contained in casing 1 and located thereon is a double-walled pressure cover 3, adapted to act on fuse member 4 when under pressure. The outer rim of 3 is supported by the annular elastic member 5 and the centre portion of 3 is supported by a part-spherical shell 6 making a line contact on or annular hard elastic member 8 fitted in shell 7. When cover B is subjected to universal perpendicular loading, e.g. on exposure to detonation waves, the member 8 is forced into shell 6 until it is filled, when the support becomes rigid and the distance moved by cover 3 is insufficient to detonate the mine. With an off-centre loading, cover 3 tilts on surface 8, and the resultant perpendicular movement is transmitted by conical recess 9 in arming member 10 to the pressure element 11 to detonate the mine. During transit, the mine is fitted with a safety washer 31, which prevents accidental detonation. On laying, 31 is removed and arming member 10 is screwed tightly down. This pushes down element 11 and the motion is transmitted to striker pin 13 via cylinder locks 14. Thus the collar 20 is caused to push past the ball-catch 32 (see Fig. 5), and starts the clockwork mechanism 18. In this condition (shown in Fig. 5) the mine is safe from detonation for a period governed by timing mechanism 18 and thus can be laid from aircraft or moving tanks. The mechanism 8 causes hollow shaft 19 to rotate and thus causes collar 23 rigidly fixed thereto also to turn (Fig. 4) until cylinder locks 25 enter grooves 33 when spring 16 forces element 11 up to retaining collar 17, and forces collar 26 down to the end of collar 23 (see Fig. 6). The mine is now armed and ready for detonation. In this condition any pressure on element 11 releases cylinder locks 14 into spaces 34 and striker pin 13 is urged forward by spring 22 to cap 35 which detonates the mine. In a modification (Figs. 7 and 8, not shown) retaining cap 17 is replaced by metal pins which are sheared on screwing down cap 10 and thus the mine cannot be made safe, any attempt to remove cap 10, releases locks 14 and detonates the mine.

Winches; driving-gear; laying or guiding ropes on or off during winding and unwinding.-A hauling winch comprises a chain wheel 4 driven by a worm wheel 2 and worm 1, the whole being mounted in a frame 8 swivelling about the axle 5 in A-shaped standards 6, so that the winch can adjust itself to the angle of pull of the load. The standards are mounted on rollers 7 for portability. The worm shaft may be operated by hand or through two-speed gearing from a shaft 1C<1>, Fig. 3. The final wheel 10 of the speed gear is fitted with a pair of retaining pawls 11 connected by a spring. By rotating the cam 14, by a hand lever on the shaft 15, the pawls are thrown alternatively out of action, thus permitting the worm shaft to rotate in .either direction at will, but preventing any reverse motion. Loads are attached alternately to the end of a chain passing over the wheel 4, the chain being kept in engagement with the wheel by a shaped guard spring-mounted on the plates 8 with its surface close to the periphery of the wheel. An unhooking device acts in both directions to release the slack-side of the chain as it is paid out by the wheel.

Filed: 1939-06-08
Abstract: 529,808. Refining cellulosic materials. CELEC CORPORATION, Ltd., and TOWNSEND, C. S. June 8, 1939, No. 16806. [Class 2 (ii)] Vegetable fibres e.g. sisal fibres are rendered soft and suitable for spinning by subjecting them to treatment with a strong alkaline solution and then with a weak solution of an acid so as to dissolve the gums, resins, and other binding substances, subjecting the separated fibres to treatment with a swelling agent which is a sodium compound e.g. ,sodium hydrosulphite, removing the harsh silicious covering on the swelled fibres by frictional rubbing, and then softening the fibres by treatment with a wetting agent e.g. a solution of a sulphonated oil. The raw fibres may be boiled in a strong solution of sodium carbonate and then soaked in a 1 per cent solution of sulphuric acid at normal temperature. The separated fibres may then be boiled in a weak solution of sodium hydrosulphite and soda ash whereby they are swollen and also bleached. The frictional rubbing may be effected by passing the fibres on to a rotary disc which operates by an oscillatory movement, the disc being finely channelled radially. The fibres are passed over the disc by means of a conveyer belt which may also be finely channelled. The fibres may be softened by soaking them in an aqueous solution of sulphonated castor oil heated to about 90‹C. The sodium carbonate solution used in the first stage of the treatment may be rendered caustic by the addition of lime. The liquors used may be filtered, made up to the required strength by addition of fresh reagents, and then used over again for treating a fresh batch of fibres.

Title: Improvements in the production of s.n-diacetyl and s.n.n.-triacetyl cysteamines
IPC: C07C233/16
Filed: 1952-07-04
Abstract: S,N-Diacetyl- and S,N,N-triacetyl cysteamines are produced by a process which consists in causing acetylating agents to act on N-monoacetylcysteamine.  If the latter is treated at ordinary temperature with ketene there is first obtained S, N-diacetylcysteamine.  The same product is obtained by reacting acetyl chloride on a mixture of N-monoacetylcysteamine and pyridine and heating to boiling.  By prolonged action of ketene or by boiling N-monoacetylcysteamine with acetic anhydride S,N,N - triacetylcysteamine is formed.  In examples: N-monoacetylcysteamine is boiled under reflux with acetic anhydride to obtain S,N,N-triacetyl cysteamine (1) or in ether solution is treated with ketene at room temperature to obtain S,N-diacetylcysteamine and S,N,N-triacetylcysteamine (2).  The diacetyl derivative gradually splits off acetic acid in aqueous solution, especially weakly alkaline aqueous solution.  The products are blood pressure depressants (see Group VI). Specification 718,063 is referred to.ALSO:S.N-diacetyl and S.N.N -triacetyl cysteamines which have blood pressure depressant properties are prepared by the acetylation of N-monoacetylcysteamine (see Group IV(b)).  The solubility of the compounds in water is mentioned and in the examples the effect of the compounds in reducing the blood pressure of rats is illustrated. Specification 718,063, [Group IV(b)], is referred to.
