Title: Improvements in method and apparatus for fabricating air spring diaphragms
IPC: B29D22/02
Filed: 1959-11-27
Abstract: 863,355. Making air springs. UNITED STATES RUBBER CO. Nov. 27, 1959 [Jan. 12, 1959], No. 4032/59. Class 108(3). A method and apparatus for fabricating a flexible diaphragm for an air spring from a tubular flexible unit give a final product in which the cord angle remains constant. Fig. 2 shows the apparatus comprising coaxial left hand and right hand mandrels 18, 18a the former being arranged for axial movement, with inflatable bags 39, 39a the reinforced right hand one 39 having an air sealed movable collar 41 to allow controlled expansion and the left hand one 39a having a non- reinforced elastic section from near point a to its right end and a non-movable collar 41a. Coaxial right and left shaping forms 21, 21a, are arranged for both axial and rotational movement, the former having projections 37 to hold a bead wire 43. To form a spring diaphragm a disc or spool 42 is placed between the mandrels which are then closed together and a cylindrical tubular unit 44 is formed on them from some form of weftless cord fabric with a cord angle between 15 degrees and 75 degrees but preferably between 40 degrees and 55 degrees coated with natural or synthetic rubber. A wire or cord is tied round the middle of unit 44, comprising portions 44a, 44b contracting it and spool 42. Left shaping form 21a is fully advanced, right bag 39 inflated to expand the right hand end of the fabric unit 44 the edge of which is turned back over the form 21a before deflating the bag. Right shaping form 21 carrying bead wire 43 is advanced, contacts the other shaping form and pushes it until stopped by a stop 46 with the right hand end of the diaphragm in a relaxed position over the left hand end. The edge is turned back on to the right form 21 and the left form retracted. The left bag 39a is partially inflated the two surfaces of the fabric unit adhering to each other where they are in contact as in Fig. 8. The preliminary shaping of the fabric unit distorts the edge cord angle as in Fig. 8a but the cord angle is corrected as in Fig. 9a by retracting stop 46 and stretching the free outer portion by fully advancing right shaping form 21, the rotational freedom of the components of the apparatus facilitating this operation. Bag 39a is then expanded the elastic section stretching the edge of the left hand portion of the fabric unit correcting the cord angle on the inner ply of the diaphragm as it adheres to the outer ply. The left edge is turned over the bead wire and other edge the right form 21 retracted and the "turn up" and body of the diaphragm adhered by rotating the mandrels and running a hand roller over the superposed plies before fully deflating the air bag. A further flange of rubber may be added at the large diameter end of the diaphragm. A layout of the pneumatic valves for performing the various motions described is depicted in Fig. 12 (not shown). Specifications 773,069 and 860,596 are referred to.

Abstract: 956,301. Cathode-ray tube circuits. ENGLISH ELECTRIC VALVE CO. Ltd. July 9, 1962 [Nov. 13, 1961], No. 40499/61. Heading H4T. " Clearance " and erasure of the charges stored on the storage mesh of a direct-view storage tube are effected by a single switching operation. During normal operation of the tube, i.e. when charges are being " laid-down " on the storage mesh M (Fig. 1) by the writing gun W, the backing electrode B of the mesh receives its normal potential Va from terminal 8 via the ganged switch 1, 2 in the right-hand position. At this time capacitor 12 charges via resistor 10 from the voltage supply V1 (terminal 11) for the collector mesh C. When clearance and erasure are required (i.e. after the stored charges have been rendered visible on the fluorescent screen P by means of the " flood " gun F) the switch is put in its lefthand position. The backing electrode B now receives the comparatively high potential V1 across capacitor 12 (about 210 volts) and the " clearance " step commences (t0, Fig. 2). Capacitor 12 then discharges via resistor 9 to a potential Vb (Fig. 2) determined by resistors 9 and 10 (t1, Fig. 2), the potential Vb being such that Vb - Va is equal to the required erasure potential Ve (about 13 to 20 volts). The periods t1 - t0 and t2 - t1 are preferably 50 and 250 milli-seconds respectively. It is stated that the switch may be either mechanical or electronic.

Abstract: 1377358 Automatic control of course LICENTIA PATENT-VERWALTUNGS-GmbH 23 Aug 1968 [14 Oct 1967] 40539/68 Heading G3R In a torpedo proportional navigation control system, the control is effected initially along a wire and in the final phase is effected by a self guidance device, mounted on the torpedo and operated acoustically. To prevent the torpedo aiming directly at the noise source, (the propeller wake) the point of impact with the target ship is advanced from the stern of the ship. Control of the missile is effected with regard to angular bearing rates of charge and to produce the displacement of the impact point, a term is injected into the control system for a predetermined interval, so as to produce an angle-of-squint track. In switching from the proportional navigation to the angle-of-squint the amplification factor of the guide system is set to unity and the injected term is applied for an interval which is a function of the amplitude of the time variation of the injected term.

Title: Improvements relating to gas detectors
IPC: G01N7/10
Filed: 1958-12-17
Abstract: In a gas warning system in which electrical contacts are closed to actuate a warning device by means of a diaphragm responsive to gas pressure resulting from diffusion of the gas to be tested through the walls of a porous container, means are provided to cause the warning device to continue to function even if the contacts subsequently open.  As shown in the Figure, a chamber 3 having a porous wall 4 is filled with carbon granules inserted through the opening closed by screw 6.  A hollow screw 11 supports a capsule 7 having a diaphragm 8 which is, in turn, connected to a stem 9 sliding in a bearing 10 and having a contact 14.  As a result of explosive gases <PICT:0867750/III/1> which are heavier than air entering the chamber 3 through the porous wall at a slower rate than air diffuses outwardly, subsequently being absorbed by the carbon granules, and passing into the capsule 7 through said hollow screw 11, the contact 14 is brought into touch with contact 15 (adjustable by screws 17 and springs 18) and this connects the lamp 25 and bell 26 into circuit with battery 22 and the warnings are given.  At the same time coil 23 of a latching relay having contacts 24 is energised whereby opening of contacts 14, 15, does not open the warning circuits.  A switch 28 provides for reinstatement of the latching relay in the open position, switch 27 renders the use of the bell optional and press switch 30 is useful for testing the system.  Alternative latching arrangements (not illustrated) are mechanical latching of the relay or comprise a solenoid or other device which it latched in the operative condition.  According to the Provisional Specification, the solenoid may be in parallel with the warning lamp or other device; and the use of a latching relay is said to permit the use of a secondary power supply to an alternative warning device, e.g. a battery operated lamp may be used alternatively to an electric bell requiring more power.  The apparatus is suitable for warning of the presence of explosive or inflammable gases which are heavier than air and so tend to collect in the bilges of boats and in store cupboards in caravans and outbuildings.
