Title: Winding arrangement on board ship for hoisting and lowering a load such as a lifeboat
Inventor: SCHAT MARINUS LEENDERT
IPC: B63B23/04
Filed: 1960-10-18
Abstract: 965,417. Winding and paying out apparatus. SCHAT DAVITS Ltd. Oct. 18, 1960, No. 35642/60. Heading B8B. In winding arrangement on board ship for hoisting and lowering a lifeboat there is an auxiliary motor which, either direct or through the intermediary of toothed wheels, is non- detachably connected to the drum on which one end of the winding tackle is wound, the arrangement being such that the auxiliary motor exerts sufficient force to keep the tackle taut, although a movement of the drum under the influence of forces acting on the tackle as a result of the boat's weight, is not hampered. As shown in Fig. 1, there are two drums 1, 15, each connected by gearing with a respective auxiliary motor 28, 30. A single main driving motor 10 drives the drums 1, 15, through gearing 11, 12 and respective clutches 7, 21. The gear 12 is rigid with a ratchet wheel 25 which co-operates with a pawl 26. A clutch 35 can be operated by means of a control 37 so as to directly connect the drive of the drum 15 with the drive of the drum 1. In operation, the clutches 7 and 21 are engaged when it is desired to rotate the drums 1, 15, in the hoisting direction by the action of the motor 10. The drums are held against rotation in the direction of lowering by the ratchet 25 and pawl 26. When it is desired to rotate one of the drums 1, 15, in the direction of lowering the respective clutch 7, 21, is disengaged. If both clutches 7 and 21 are disengaged both drums may be rotated in the direction of lowering together by engaging the clutch 35. Brakes 6 and 20 are associated with clutches 7 and 21. In a modification (Fig. 2, not shown), the pawl and ratchet 26, 25, is combined with the clutch 35. In Fig. 3 a single auxiliary motor 95 is provided for two drums 80, 81, which rotate together. In the modification shown in dotted and dot-dash lines in Fig. 3 a separate auxiliary motor 97, 99 is provided in respect each drum 80, 81. The rope passes off each drum to a tackle block 107 and the end of the rope that would normally be fixed, is wound on the drum 98 of the respective auxiliary motor.

Title: Anion exchange compounds
IPC: B01D15/04
Filed: 1953-12-24
Abstract: Polymers and copolymers of vinylimidazole and its derivatives which are capable of swelling in water and which have been cross-linked to the point of insolubility in water are useful as anion-exchange compounds.  The initial monomer may be N - vinyl - imidazole, N - vinyl-2 - methyl - imidazole, N - vinyl - 2 - phenylimidazole, N - vinyl - 2 - methylol - imidazole, N - vinyl - 2 - hydroxy - ethyl - imidazole or N - vinyl - 4.5 - benzimidazole.  Cross - linking may be effected (a) by reaction of the basic nitrogen atom of the monomeric N-vinylimidazole &c. with a polyfunctional quaternaryacting compound such as 1.4-dichlorbutane and a 1,a 4-dichlorodurene and subsequent polymerization; (b) by reaction of polymerized N-vinylimidazole &c. with a polyfunctional quaternaryacting compound; or (c) by copolymerization of the monomeric N-vinyl-imidazole &c. (which may have been rendered quaternary) with a bifunctional vinyl compound such as divinyl benzene or divinylimidazolidone.  The quaterning agents used in (c) may be those mentioned in (a) or may be benzyl chloride or an alkyl halide or sulphate, which may also be used in (a) and (b) in conjunction with the other quaternizing agents.  The N-vinyl-imidazole may be copolymerized with styrene, acrylonitrile, vinyl acetate, vinyl chloride, vinyl pyrrolidone or an acrylate.  In the polymerization reaction hydrogen peroxide may be used as catalyst.

Title: Frequency stabilised signal generating circuits
IPC: H03K17/18
Filed: 1960-10-21
Abstract: 959,387. Automatic frequency control systems; transistor amplifier circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 21, 1960 [Nov. 9, 1959], No. 36168/60. Headings H3A and H3T. A multivibrator is frequency stabilized by its output being applied through a resonant circuit tuned to the frequency required to a phase detector also fed directly by the multivibrator, to derive an AFC voltage fed back to a control electrode of the multivibrator. The resonant circuit may be a transistor emitterfollower with tuned circuit 51, 50 between its collector and base, and an inductor 55 in its collector circuit to produce a constant 90 degrees phase shift from the emitter in addition to the variable phase shift (positive or negative) dependent on any frequency shift of the multivibrator from that of the tuned circuit. The positive going half-cycles of the emitter follower output are converted to square waves by the saturation of transistor 63 of the phase detector 16 and the multivibrator positive going square waves applied to the other transistor 68 are arranged to be in phase quadrature, i.e. overlap one half of the other positive going square wave input to the phase detector. The common collector voltage therefore varies in magnitude and sense dependent on any phase variation and this is converted to a variation about zero volts by bias circuit 74, 77, and applied as AFC of the transistor multivibrator 10. The AFC controlled multivibrator may be used for the clocking of binary data pulses as described in Specification 902,450 since, although in the latter the multivibrator phase is necessarily clamped in correspondence with transitions (presence of pulses), in the incoming data irrespective of jitter in the latter, a continuous absence of pulses might otherwise produce phase error drift of the multivibrator resulting in a loss of one or more data bits before re-synchronizing by the clamping.

Title: Improvements in or relating to temperature responsive motion transmitting devices
IPC: G01K5/44
Filed: 1962-09-24
Abstract: 951,717. Temperature responsive actuating elements. ANTIOCH COLLEGE. Sept. 24, 1962 [May 14,1962], No. 36246/62. Heading G1D. A temperature responsive notion transmitting device comprises a casing 11, Fig. 1, containing a material 19, the volume of which varies with temperature e.g. wax or mercury, the casing having an elongated portion provided with spaced inwardly sloping shoulders 25, 26 defining a necked-in portion, a resilient, deformable, sealing plug 20 e.g. of a resilient material such as rubber, seated within the necked-in portion, and arranged so that the force exerted by thermal expansion of the material 19 moves the plug 20 within the portion 24 of the casing. The casing 11 is of tubular form and has one end closed by a disc 15 and a deformable plug 16, preferably of rubber or like material, the casing being crimped, as at 17, to provide a fluid tight seal. The temperature expansible material 19 is enclosed between the plug 16 and the sealing plug 20, the necked-in portion 24 of the casing 11 serving to provide a fluid tight seal with the plug 20. As the material 19 expands, the plug 20 is forced to the right in Fig. 1 and in so doing it pushes a piston 23 slidable in the casing 11, through the intermediary of a disc 21 e.g. of a near resistant plastics material. The piston 23 may be made to actuate any suitable device and the casing 11 and disc 15 are preferably of a thermally conductive metal. The plug 16 and disc 15 may be dispensed with where the material 19 is contained in a bulb with one end closed (Fig. 2, not shown), and the casing may be crimped in the manner shown at 17, Fig. 1, close to the left hand end of the plug 20 to prevent the plug from being completely withdrawn from the necked-in portion 24 on contraction of the material 19 (Fig. 3, not shown). Furthermore, above the necked-in portion 52, Fig. 4, the diameter of the casing 50 may be again decreased, preferably to below two thirds of the value of the diameter of the casing where it contains the expansible material, so that the distance moved by the piston 57 will be greater than that moved by the lower end of the plug 51. A further embodiment is shown in Fig. 5, wherein the temperature expansible material 69 is contained in a cup-shaped element 61 closed by a cap 63 which has a depending guide 66 for a piston 71, the guide being formed with a necked-in portion 67 to provide a fluid tight seal with a resilient plug 68.

Filed: 1960-10-24
Abstract: 962,817. Fibrous fabrics; lap forming. FERRO CORPORATION. Oct. 24, 1960 [June 13, 1960], No. 36396/60. Headings D1N and D1R. A method of forming fibrous mats consists in entraining dissimilar fibrous materials separately in a plurality of air streams down hollow shoots and depositing the fibrous material successively on to a movable support or conveyer, whereby a mat of superposed layers of dissimilar fibrous material is formed with the fibres of adjacent layers interlacing at random directions to form an interfacially interlaced stratified mat. Preferably the support or conveyer is in continuous motion during the deposition of the fibrous material and the hollow shoots oscillated transversely to the movement of the conveyer. Air streams containing entrained resin binder may be directed concurrently with the air streams entraining the fibrous material. The fibrous material from different shoots may differ in chemical composition or in physical texture and the rate of discharge from each shoot may be different in order to form layers of different thickness. Fibrous material forming external layers are preferably finer than that forming an internal layer or layers e.g. glass and jute fibres. Preferred apparatus for performing the above method is shown in Fig. 1 and consists generally of a strand supply and chopping section 1 and a mat forming section 2. Continuous strands 4 of fibrous material are fed from balls 3 to cutting zones 13 and are thence induced to flow downwardly by gravity through hollow bearings 16 aided by currents of air from blowers 15, directed through ducts 17,flexible hoses 18 and finally through hollow shoots A, B, C. The air currents entrain the chopped fibrous material and expels them in a cascade on to the movable conveyer 20 to form a mat 26. The shoots A, B, C are arranged in tandem and there is mounted on and parallel with each shoot, tubes 24 for distributing powdered resin binder 25 simultaneously concurrently with the chopped strands 4a. The powdered resin is continuously supplied by gravity from hoppers 42 via. flexible tubes 43 and another flexible hose 44 provides air from blower 15 to aid distribution of the resin binder through tube 24. A suction box 27 is provided under the upper run of the conveyer to increase the compacting of the mat. Additional bonding material is added from trough 32 and the mat is sprayed with liquid e.g. water from sprays 34, 35 to further compact the mat before it passes into curing oven 38.
