Title: Improvements in or relating to pendulum devices, for example, for ships' stabilising systems
IPC: B63B39/14
Filed: 1937-11-25
Abstract: 506,353. Automatic control systems. STEINEN, C. VON DEN. Nov. 25, 1937, No. 32574. Convention date, Nov. 25, 1936. [Class 38 (iv)] Attitude.-A pendulum 1, employed for example in ship-stabilizing systems as described in Specification 484,294, [Group XXXIII], wherein a pair of stops 3, 4 operating as electric contacts and closely embracing the pendulum are caused to follow up the movements of the pendulum by selective energization of a reversible electric motor, is arranged to swing about its centre of oscillation 2 by causing the motor to move the pendulum bearing. The pendulum is preferably suspended at 1a from the follow-up device, consisting of a sector 6 pivoted at 2 and actuated by worm gear 7 from the motor, the axis of the follow-up device passing through the centre of oscillation of the pendulum. Inertia effects are in this way overcome since the pendulum mass remains substantially at rest.

Title: Improvements in or relating to unsupported sheet material
IPC: D06N3/06
Filed: 1966-07-20
Abstract: 1,143,109. Cellular coatings, L. FELT. 20 July, 1966 [27 Jan., 1966], No. 32660/66. Heading B2E. A floor- or wall-covering material comprises a cellular layer of polyvinyl chloride, or of vinyl chloride co-polymerized with a minor amount of vinyl acetate of vinylidene chloride, or a mixture of vinyl chloride homopolymer with vinyl chloride copolymerized with a vinyl amount of vinyl acetate of vinylidene chloride or both, an intermediate layer of woven openmesh fabric, and a non-cellular of vinyl composition layer composed of resin comprising the same or another resin from those specified above, integrated through penetration of resin composition via the openings in the fabric from vinyl layer to vinyl layer. The sheet material may be produced by certain methods of spreading or calendering well known to the art. In the example a spreadable layer of composition based on polyvinyl chloride which is plasticised and can contain fillers, heat stabilizers or colouring matter and containing a blowing agent, is spread by a coating knife supported by a rubber-covered roll on a continuous band of aluminium foil; the continuous web of open weave or open mesh fabric, for instance net, is laid into the spread composition; the compined sheet is heated to temperature which will gell the layer and initiate its expansion; the composite layer is smooth on a smoothing calender, the layer cooled and a layer of composition having the same vinyl basis than the first layer but without the blowing agent is then spread on the fabric. The foil is heated until gelation of the second layer takes place and expansion of the first layer is substantially completed. The assembly is cooled and the sheet material removed from the aluminium foil. The resulting sheeting may be embossed before coating or decorated in any desirable manner during or after manufacture. Polymers exemplified from the two layers are polyvinyl chloride, vinyl chloride copolymerized with a minor amount of vinylidene chloride a mixture of vinyl chloride homopolymers with vinyl chloride copolymerized with a minor amount of vinyl acetate, a mixture of vinyl chloride homopolymers with vinylchloride copolymerized with a minor amount of vinylidene chloride and a mixture of vinyl chloride homopolymer with vinyl chloride propolymerized with a minor amount of vinyl acetate and minor amount of vinylidene chloride. The reinforcing intermediate fabric can consist of fabric made from natural or man-made fibres of mixtures thereof including fabric made from animal hair and jute.

Title: An improved molten metal feeding device
IPC: B22D17/30
Filed: 1945-12-03
Abstract: 604,792. Casting-machines. ARNOLD, J. C. (Lester Engineering Co.). Dec. 3, 1945, No. 32675. [Class 83 (i)] [Also in Groups XII and XXVIII] Pouring &c. apparatus.-A device for feeding molten metal comprises a reservoir 1, a pipe 2 with rising and falling parts, means for drawing up the metal into the pipe and contact means actuated by the metal to stop the drawing-up means. The melting pot 1 has a rising pipe 2 connected to a riser 10 which is connected by a downwardly inclined pipe 2b to a chargereceiving chamber 3. This has a spring-closed gate 16 which can be opened to deliver its charge to a casting machine 5 and a suction pipe 26 leading to a spring-opened valve 33 and suction pump 35. The pipe 26 is also connected to the riser 10. The valve 33 can be closed to the pump 35 by a solenoid 39 and then admits air to the pipe 26. With the parts in the position shown, the valve 33 causes the chamber 3 and riser 10 &c. to be evacuated so that metal is drawn up the pipe 2, flows into the chamber 3, and rises to level A, Fig. 2. Here it contacts an insulated electrode 32 connected by a line 53, Fig. 1, to a solenoid 52, the other end of which is connected to a supply line L2. The other supply line L1 is connected by a line 43 to the riser 10 so that the solenoid 52 is energized, thus closing a switch 47 to connect the lead L1 to a terminal 54, thus keeping the solenoid 52 in action, even when the metal in the riser 10 falls, and energizing the solenoids 39, 41. The former operates the valve 33 to admit air to the riser 10 and allow the metal to flow back instantly to the pot 1 until the level P, Fig. 2, is reached and the latter opens the gate 16 to discharge the chamber 3 into the pressure chamber 4 of the casting machine. To repeat the cycle of operations, the switch 46 is pressed to open the circuit to the solenoids 39, 41, 52. The amount of metal delivered can be varied by adjusting the position of the cylinder 20. In modifications, the metal may be pumped or forced into the pipe 2. In another modification, the electrode 32 is mounted in a tube 64, Fig. 3, adjustable in the chamber 3 to vary the charge of molten metal. Heating coils 11, 12, 13, Figs. 1 and 2, may be used to keep the metal molten.

Abstract: 893,838. Loud-speakers. TANNOY Ltd. Jan. 1, 1960 [Oct. 14, 1958], No. 32773/58. Class 40 (4). In a moving coil loud-speaker having two diaphragms, driven by respective speech coils, in separate air gaps arranged in series in a magnetic circuit, with one air gap having a higher flux density than the other, a magnetic shunt of small enough cross-sectional area to be appreciably saturated by the magnetic flux bridges the other air gap. A low-frequency diaphragm 1 is operated by a coil 14 moving in an annular air gap 15 surrounding one end of a cylindrical polepiece 16, while a high-frequency diaphragm 2 is operated by a coil 10 moving in an air gap 18 at the opposite end of the polepiece 16, a sleeve 21 constituting the ring magnet of the loud-speaker. A plate 19, centred about the axis of the system by a non-magnetic ring 23, completes the magnetic circuit between air gap 15 and sleeve 21 and a thinner plate 20 in closer proximity to coil 17 than plate 19 is to coil 14, completes the circuit at the other end of the polepiece 16. A flange 27, of small cross-sectional area so that it may be easily saturated, on plate 20, shunts the air gap 18 but does not alter the flux through the air gap 18 by a significant amount, although it causes the flux in air gap 15 to be appreciably increased (up to 20%), thus allowing a greater energy input to be used with the larger diaphragm 1.

Retting.-In the treatment of flax straw, hemp, ramie, and the like to produce a fibre having a high gloss and adapted, without scutching, to be spun by machinery such as is used in cotton mills, and also to produce furfural, the straw, preferably unretted, is first digested in plain water in an autoclave at 182 C., then furfural is distilled off and the material boiled for 4-6 hours in 5 per cent caustic soda at 150- 170 C. with the optional addition of a plasticizer such as 1¢ per cent Turkey red oil and ¢ per cent linseed oil to the weight of straw treated. The product is washed preferably in soft water, then immersed in an acid bath preferably hydrochloric acid of ¢-2 per cent strength. By this treatment the pulp contains flax fibres in which the nodes have been destroyed or weakened and also shive or fibre of short length and can be dried and treated by carding or similar machinery to yield fibres of a length suitable for spinning and short fibres which latter if pure can be dissolved for making artificial silk or if containing sub-normal (Beta and Gamma) cellulose can be used for making paper, cardboard and insulating materials. By reducing the duration of the treatment stronger flax fibre is obtained. The drying operation may be omitted, the mixed fibres being then sorted into their respective lengths by a wet method using screens such as are used in paper mills, the short fibres going to the paper machine and the long fibres being dried for spinning.
