Title: Improvements relating to fastening devices
IPC: F16B5/10
Filed: 1943-11-17
Abstract: 570,707. Rotary stud fastening for cowlings &c. SUMMERS, J. M. Nov. 17, 1943, No. 19201. Convention date, June 5. [Class 44] In a fastening of the kind in which a stud and a socket are engaged or disengaged by relative rotation, the socket is provided with a cover to render it fluidtight. The fastening is particularly suitable for securing aeroplane inspection covers, cowlings, or similar parts where it is desirable that the fastening should itself be gas-tight or liquidtight, as on pontoons of flying boats, aeroplane cabins, or receptacles for liquids or gases. As shown the fastening comprises a stud 20 rotatably mounted in a cup 18 secured to the cover 11, a compression spring being housed in the cup below the head 21 of the stud, the stem of the stud extending through the bottom of the cup and having a cross-pin 22, and a socket member 17 secured to the seating or support 14 for the cover, the seating having a rubber or fibre gasket 32. The bottom of the socket has an aperture to allow passage of stud and cross-pin in one angular position, and externally presents cam surfaces 23 over which the ends of the cross-pin 22 ride as the stud is rotated, the cam surfaces leading to detent recesses. The sealing cover is in the form of a cylindrical cup 25 slid into place on the exterior of the socket, the entry of the socket being limited by a shoulder 27. The shoulder may be conical as shown, the mouth of the cup being correspondingly flared, or may be of rectangular or other form. The cup may be of sufficiently tight friction fit on the socket to secure it and effect sealing, or, if necessary, a sealing compound or adhesive may be applied to the interior of the cup before fixing in place. The cup may also be filled with a water-proof grease or other compound 30 to prevent water condensation in the bottom of the socket and to act as a lubricant. The cup 25 may be of metal, plastic, or other material.

Title: Improvements in electric remote-control apparatus
IPC: G05D3/16
Filed: 1939-07-01
Abstract: 530,745. Valve relay circuits. ELLIOTT BROS. (LONDON), Ltd., and PIZZEY, C. F. July 1, 1939, No. 19202. [Class 40 (v)] [Also in Group XXXV] A remote-control apparatus comprises transmitters 1, 7, which may be of the character described in Specification 405,043, [Group XXXV], and a controlling differential relay 3 having windings which compare the currents transmitted and operate either of the contacts 3a, 3b when unbalance occurs. When operated, contacts 3a, 3b, short circuit resistances 34a, 35a and remove the grid-bias (normally derived from a transformer winding 31 and half-wave rectifier 32) of gas-filled valves 11, 12 which are thus made conducting. The anodes connected respectively to the windings 8a, 8b over windings 17, 16 of a phase-reversing transformer so that only one set at a time is made conducting. The valve-cathodes 13 are connected to the motor-brush 8c over contacts 19 of a thermal switch which ensures the cathodes reaching working-temperature before anode-potential is applied. Thus, when the a.c. supply 21 is switched on to windings 16, 17 over the. contacts 18a, 18b of switch 18, the slow-acting heater 27 is warmed and after, say, 45 seconds, during which the cathodes are warming, opens at contacts 25 the short circuit of an electromagnet 23 and main heater 20, so that the latter closes contacts 19. Electromagnet 23 opens mercury switches 24, 26 so that heater 27 cools and contact 25 recloses ; switch 24 however prevents shortcircuiting of heater 20 until or unless the supply 21 is cut off or fails, in which case the cycle must be recommenced. Valves 11, 12 are duplicated to guard against failure, but each may be tested by means of contacts 18c, 18d, of the change-over switch 18 and a further switch 38 which connects it to an indicator lamp 41, the switch 43 being also moved to cut out the bias-resistances 34a, 35a. A further differential relay 4 is provided with windings less sensitive than, and in series with, those of relay 3 and is operative when, due to failure of the supply or to faults in the apparatus, relay 3 fails to operate in the time allotted. The contacts 4a, 4b of the relay are paralleled to a heater coil 44 which is energized by transformer winding 37 and has a delay of, say, 60 seconds, after which contacts 45 open and de-energize a constantlyenergized heater 47 which, after a further delay, allows its contacts 48 to open the no-volt coil circuit 49 of the pump motor. At the same time magnet 50 is de-energized and operates an indicator lamp 52. During starting up, when there may be undue delay due to the heater 27 combined with an unbalanced condition, the protective action is prevented by closure of manual switch 53 until, due to restoration of balanced conditions, lamp 52 goes out. Indicators 5, 5a, 6 are provided adjacent the transmitter 1, 7 and receiver.
Patent GB-167467-A (GB)
IPC: H02H9/08
Filed: 1921-07-16
Abstract: 167,467. Ateliers de Constructions Electriques du Nord et de l'Est. Aug. 4, 1920, [Convention date]. Protective arrangements.-In the protection of a three-phase system against earths, each phase from the bus-bars A, B, C is connected through a winding a, b, c on the core of a large singlephase transformer, the windings being so connected that normally the ampere-turns in the three windings mutually balance and the reactance of the transformer is negligible. When, however, one of the phases becomes earthed, a heavy capacity current flows in the corresponding transformer winding, which consequently becomes unbalanced and inserts its total reactance in the circuit to limit the fault current in the systems. The Specification as open to inspection under Sect. 91 (3) (a) describes also an arrangement in which the transformer may carry a secondary winding d, Fig. 4, (Cancelled) connected to the trip coil r of a main circuit-breaker, so that a disturbance of balance in the transformer energizes the coil d and trips the circuit-breaker. This subject-matter does not appear in the Specification as accepted.

Title: Automatic analysing device for the diagrams of measuring recorders or similar recording instruments
IPC: G01D9/00
Filed: 1970-04-22
Abstract: 1,272,026. Analysing records. KIENZLE APPARATE G.m.b.H. 22 April, 1970 [26 April, 1969], No. 19263/70. Heading G4H. An apparatus for analysing bar diagram records, detects the information on the records photo-electrically. Light from lamp L is conducted by light guides S to two reading heads, and the reflected light from the reading heads is fed to photo-cells FA and FB. The bar diagram comprises a number of tracks, each track comprising two semitracks; information may be recorded on one or other of the semitracks or on both together, the choice of recording configuration itself carrying information. A first track carries the characteristic of the workpiece number, the next track carries the workpiece number. A third track carries an analogue of the time for which a machine is operating, the next three tracks carry the time for which the machine is stopped, the reason for the stoppage being indicated by the track number and the form of recording on that track. The workpiece number and its characteristics are indicated by pulse marks on the record and these are counted by means of a counter, comprising decades 10.0 to 10.3. The output of this counter is fed to a decoder 15, which in turn actuates a tabulating machine. The length of time for which the machine is running or stopped, is measured by counting gated pulses using the counter comprising decades 10.0 to 10.4, with a preliminary decade 10.-1, which is rounded up or down at the end of the count, by means of round off unit 12. The cause of a stoppage is indicated by a number between 1 and 9, which is recorded on decade 10.4. The transfer of information from the various decades of the counter is controlled by means of a ring counter 13. The control of the analyser as a whole is by means of a logic unit employing two ring counters (20), Fig. 4 (not shown), and (21). The unit also employs NOR gates (27), OR gates (33), (34) and (35) and AND gates.

Title: Improvements in braiding machines for making lace and the like
IPC: D04C3/38
Filed: 1920-07-07
Abstract: 147,218. Laurent FrÞres et Cie. Sept. 17, 1917, [Convention date]. Braiding-machines.-A device for stopping and starting bobbins of lace braiders at and from the points of intersection of the sinuous raceways, according to pattern, by acting on the movable driver arms b, consists of a series of plates c mounted below the centre disks d on jacquard - controlled axles h. The plates c encircle the hubs a<1> of the continuously-rotating driving-gears a and when the axles h are,pulled down against the action of springs k the plates c are depressed out of engagement with the cam portions b<1> of the driver arms b, leaving the arms b free to drive the spindles m' round through 180 degrees. At the same time, a piece e mounted below the plate c passes through a gap g<1> in a collar g on the hub a<1> and is thus retained in the depressed position whilst the arms b drive the spindles round. The piece e is then passed up through another gap in the collar g, situated diametrically opposite the gap g', by the spring k, the jacquard having meanwhile ceased to act. The corresponding upward movement of the plate c puts the driving-arms b out of action and leaves the spindles m<1> resting in notches of the plates. The engagement &c. of the spindles m<1> is facilitated by pointing the lower ends m.

Abstract: 706,354. Non-return valves. MUNTZ & CO., Ltd., A. Aug. 1, 1952 [Aug. 16, 1951], No. 19387/51. Class 135 In a non-return valve comprising a number of resilient laminae 24 clamped at their root ends between side seat-plates 21 and intermediate, alternate, seat members and stop plates 29, 27, the seat members having ribs 26, 31 between which and the stop plates the laminae are clamped, distortion of the laminae due to clamping is prevented by curving each lamina transversely, either over a short length as at 33 in which case the curved part is accommodated in a recess in the stop plate, or over the whole of the lamina, when the curvature in the clamping region is removed by the clamping. Alternatively, the curvature may extend over the clamping region only. The clamping region extends from the upper ends, Fig. 2, of the stop plates 27 as far as relieved portions 35. The ribs 26, 31 are interconnected at the valve outlet by crossmembers 39. Streamlined cross-members may also interconnect the ribs at the inlet end of the valve and a flared inlet may be provided. Cutaway portions 42 on the seat members result in the free ends of the laminae extending somewhat beyond the actual seating surface when the valve is cold, the laminae being made generally of material having a lower coefficient of expansion than the other parts of the valve. This arrangement enables the laminae to seat satisfactorily when cold despite deposits of carbon on the seat members. The parts of the valve are clamped together by two end bolts between which pressure is exerted by spring strips 44. In a modification, the valve parts are arranged for flow in the opposite direction, and the whole of each lamina is given a slight curvature. Specification 580,171 is referred to.

Abstract: 498,892. Boxes for cigarettes; igniters. MARPLES, S. A. July 15, 1937, No. 19604. [Class 18] [Also in Group XI] The lower end of a box for cigarettes &c. is closed by a springy or spring-loaded plate h which can be pushed down, as shown in dotted lines, to allow a cigarette to slip out under the adjacent side wall of the box. The discharged cigarette is arrested against stops m bent up out of the plate or by separate stops n, and when the plate returns to its normal position, an arm A tilts the cigarette and facilitates taking hold thereof. A recess p allows the next cigarette to be discharged to take up a position adjacent the delivery aperture. The plate h is a single plate and rests on a transverse member j, but it may be constituted by two separate plates hinged to a bar and acted upon by separate springs. In an alternative construction, the rod is absent and the centre of the plate p is acted upon by a leaf spring resting on rods o, the plate and spring being rigidly connected at their centre portions. The plate h may also be cut out to constitute a central tongue with a turned-up end to form a stop and surrounded by a #- shaped springy portion. The box shown is divided into compartments by ribs q, but in a single compartmented box, the plate h is rigidly attached at one end to a side wall of the box. The cigarettes in the box can be urged towards the delivery aperture by spring pressure. The top of the box is covered by glass g or houses an ash-tray, flint or electric lighter, &c., and the lighter may be connected to the plate h so that depression of the latter operates the lighter.

Abstract: 148,757. Souczek, F. May 29, 1919, [Convention date]. Picking-motions; checking shuttles.-In means. for producing reciprocation of bodies, such as the shuttles of looms, sets of rollers M arranged at the ends of the path of the body S and, in looms, either stationary or oscillating with the lay, are rotated constantly in opposite directions by crossed belts and toothed gearing Z, z from the batten shaft P, or by flexible shafts, gear-wheels, &c., and are provided with stationary or rotating electro-magnetic windings i, which are excited to produce driving contact between the body S and rollers M. The shuttle, which is provided with an iron base, is thrown from one set of rollers to the other through the shed and is stopped at the ends of its travel partly by the rotation of the rollers and finally by electro-magnetic brakes B, which are brought fully into action when the shuttle bridges contacts D. A switch roller K operated by the picking-shaft carries contacts I, II, III so arranged in relation to the other electrical connexions, shown in Fig. 8, that the rollers M and the brakes B are brought into operation at the required times. Contacts H broken by the weight of the shuttle prevent premature throwing of the shuttle, and the use of resistances F across the contacts D together with the arrangement of the main switch contacts prevents sparking.

Title: Welding wire advancing unit
IPC: B23K9/133
Filed: 1970-04-23
Abstract: 1286396 Welding by fusion ESAB Ltd 23 April 1970 [25 April 1969] 19623/70 Heading B3R Welding wire feed apparatus comprises a pair of rotors 23, 25 supporting, and interconnected by, roll axles arranged at angles to the axis of rotation of the rotors, each axle mounting a wire-engaging roll and being so supported that relative angular displacement between the axle and the rotors is possible, and spring means acting on one of the rotors, such as rotor 25, to tend to cause relative angular displacement of the rotors and an increase in the angle between the axis of rotation of the rotors and the axles. In one embodiment, as shown, each of three axles 31-33 is supported by spherical bearings 34, 35 in the respective rotors 23, 25. These bearings allow relative angular displacement between the axles and rotors, in any planes through the axle axes. Rotor 25, which is keyed to shaft 26 of motor 15, is slidable thereon under the action of spring 38. In urging the rotors together, this spring tends to cause relative angular displacement between the rotors, urging the axles 31-33 to take up positions at greater angles to the rotor rotational axes. Thus the rolls 28-30 are urged into engagement with a welding wire by the force of spring 38. Ends of axles 31-33 projecting beyond rotor 25 carry counterweights 47-49 which, in operation, compensate or indeed over-compensate any centrifugal force tending to decrease the pressure of the rolls on the wire. The apparatus forms part of a gas-shielded arc welding gun, a welding cable 3 being detachably plugged to one end, and a gun barrel 4 to the other end of a housing of the apparatus. A tubular member 6 of the cable transmits welding current to a contact block 10; thence the current passes through housing 12 to contact tube 14 which is in connection with wire guide 40. An annular gas passage 8 in the cable is defined between member 6 and a wire guide (Fig. 2, not shown). Disposed in the passage 8 is a conductor 9 for supplying motor 15 via a leveroperated switch 46. In another embodiment (Fig. 4, not shown), only two roll axles are used; and each roll has a concave wire-engaging surface.
