IPC: B23K9/133
Filed: 1928-11-23
Abstract: 301,043. British Thomson-Houston Co., Ltd., (Assignees of Steenstrup, C.). Nov. 23, 1927, [Convention date]. Heating by electricity.-An electric wire feed for automatic or semi-automatic metallic arc welding machines, comprises a feed roll engaging the arcs arranged to rotate on an axis inclined to the line of feed and mounted in a support rotated about this line. The feed rolls are freely mounted on pins 2 in bushings 3 that are carried by cupshaped members 4 clamped to a casing 9, which is keyed on a hollow shaft 11 rotated by a feed motor 12 through bevel gearing 13. The bushings are adjusted by screws 6 to suit the size of wire, and are forced against the electrode wire 7 by a rubber washer 8, and are prevented from rotating by pins. The rolls are tilted by angular adjustment of the members 4 after first loosening the clamping rings 10, so as to effect the feed of the wire in either direction. Welding current is fed to the terminal 23 and conducted to the electrode by a curved nozzle 22. The motor may be of the variable speed type connected with electrical circuits so that the speed varies according to the rate of electrode consumption in the arc so as to maintain the arc of constant length as described in Specification 139,919. In a modification the shaft of the motor is hollow and is in alignment with shaft 11 to which it is connected by spur gear. In a further modification, Fig. 4, the rollers 29 are carried in bushings 28 angularly adjusted by hand, during operation of the machine, in a casing 24 carried by the hollow shaft 25, 25<1> which is driven in either direction from a constant speed motor 49 by spur gear 43, 44 and friction bevel gear 46, 47, 48. The gears 46, 47 are mounted on a shaft 45 moved against the action of an adjustable spring 51 by a solenoid 50 responsive to a characteristic of the arc circuit that varies with the arc length. The rolls are radially adjustable by screws and are pressed by springs against the electrode and their bushings are rotatably adjusted so as to vary the rate of or reverse the feed by links 33 connected to a cross head 34 which is movable in a slot in the shaft 25 and is connected to a hollow rod 35 moved in a screwed bushing 39 by a nut 37. The rod is provided with a. collar 35<1> at its upper end and is held in place by a cap 38. The angularity of the rolls may also be adjusted by a solenoid.

Title: Improvements in and relating to flexible diaphragms or facings
Inventor: LAMING PATRICK BREADWELL
IPC: B29C70/68
Filed: 1957-11-08
Abstract: 901,184. Moulding flexible diaphragms. SAUNDERS VALVE CO. Ltd. Oct. 30, 1958 [Nov. 8, 1957], No. 34919/57. Class 87(2). A flexible diaphragm or diaphragm facing of polytetrafluoroethylene (p.t.f.e.), of the type used in diaphragm valves and having the head of a stud embedded in an integralboss is made by compacting uniformly distributed granules of p.t.f.e. by pressure between the lower and upper transition temperatures (20‹ and 327‹C. respectively) to form a biscuit, sintering the biscuit above 327‹C. but below the temperature at which decomposition sets in, hot coining the sintered biscuit below 327‹C., and finally quenching the hot coined moulding while it is still under pressure. The initial stage is performed with the apparatus of Fig. 3 comprising a mould 24, a main plunger 25, a second plunger 29 slidable in the cavity 28 in the main plunger, and shoulders 32, 33 for limiting the movement of the two plungers into the mould. The granular material 23 forming that part of the biscuit outside the boss is uniformly distributed by strickling, this and the subsequent compression preferably being carried out at only a little above 20‹C. Sintering should then be effected at, for example, 360‹C. for 90 min., with the biscuit supported in a cradle without being closely confined. Suitable conditions for the coining operation are a temperature of 318‹C. and a pressure of 1 ton/sq. in., using the press shown in Fig. 6. This includes upper and lower dies 41, 43 each with separate cooling jackets 45, 49. The upper die 41 has a separate central part 42 for the final shaping of the boss. It is during this stage that diametral and marginal ribs may be formed on the diaphragm which after being cooled rapidly, e.g. down to 150‹C. in 10 to 15 sec., is removed from the press. Specifications 644,008, 696,545 and 901,185 are referred to.

Filed: 1967-07-31
Abstract: 1,191,525. Latches; multiple fastenings. FORD MOTOR CO. Ltd. 31 July, 1967 [19 Sept., 1966], No. 35059/67. Heading E2A. A latch for use in a tail-door for an estate car which can be opened by an outside handle to swing about a vertical axis along its lefthand edge or by an inside handle to drop about a horizontal axis along its bottom edge as a tail-gate, can be released by operation of either handle, an interlock being provided to prevent operation of either handle after the other handle has been operated until the door is latched again. The latch is arranged at the top of the right-hand edge of the door which also has on its left-hand edge an upper latch released by operation of the inside handle only and on its right-hand edge a lower latch, which is released by operation of the outside handle only. A further mechanism may be provided to prevent release of any of the latches unless a window in the tail-door is wound down to a fully-retracted position. The upper right-hand latch has a bifurcated pivoted bolt 26, 27, Fig. 2, urged clockwise to a releasing position by a spring 33 but retainable in latching position by a detent 38 which engages a step in a plate 29 secured to the bolt. The outside handle acts on the end 62 of an actuator lever 58 coupled by a compression spring 71 to a lever 59 which rocks the detent through an extension 67. A rod 83 connected to the lever 59 releases the lower right-hand latch at the same time. Operation of the inside handle acts, in a manner not disclosed, to release the upper left-hand latch and also, through a rod 72, Fig. 3, to rock a lever 74, an arm 79 of which raises the end 45 of the detent 38 to release the upper right-hand latch. The lever 74 has pivoted to it a push rod 76 which cooperates with the end 65 of the lever 59, Fig. 2, to prevent simultaneous operation of the mechanisms actuated by the two handles. Operation of the outside handle while the inner one is operated merely results in the separation of the two levers 58 and 59. The detent 38 is held in a clockwise position after the release of 'the upper right-hand latch by the periphery 32 of the plate 29, and its end 45 cooperates with a hooked end 81 of the arm 79 to provide a further interlock which remains effective until the door is shut once more. When the taildoor window referred to above is lowered, it depresses a rod 55 to rock a lever 48 so that its hooked end 54 is moved from blocking relationship with the end 45 of the detent 38.

Abstract: 971,265. Substation circuits. TELEFONAKTIEBOLAGET L. M. ERICSSON. Sept. 29, 1961 [Oct. 7, 1960; Aug. 10, 1961], No. 35374/61. Heading H4K. To compensate for the variations in line length which may be encountered by a substation a secondary winding N4 on the speech coil N1, N2, N3, is shunted by a non-linear impedance A controlled by a resistor D, the voltage across which depends on the current received from the exchange. If the line connected to terminals La, Lb is short the voltage across resistor D reduces the impedance of A to increase the impedance of the coils N1, N2, N3. If the line is long the impedance of A disconnects winding N4. Two impedances A and two resistors D may be arranged symmetrically in a bridge to provide equal attenuation for both half-cycles of speech and to obtain regulation independent of line polarity. The impedance A may be two oppositely poled rectifiers connected in parallel. The resistor D may be linear or exponentially non-linear as-when comprised by a tungsten filament lamp shunted with a linear resistor. The substation otherwise includes a balance network with resistor RB, capacitors C and CB, and an optional non-linear resistor LS. Protection from acoustic shock originating in the receiver R is provided by non-linear device CS.
