Title: Resistance welding tubes to plates in heat exchangers
IPC: B23K11/30
Filed: 1950-12-13
Abstract: 694,661. Welding by pressure. AUSTIN MOTOR CO., Ltd., AVERY, R. W., and DANGERFIELD, K. J. Nov. 27, 1951 [Dec. 13, 1950], No. 30393/50. Class 83 (iv). In a heat exchanger formed of a series of tubes mounted in end plates, resistance welding is employed between the tube ends and the surrounding metal of the end plate by passing current from one electrode at the outer side of the plate, through the tube metal to an electrode at the inner side of the plate close to the tube. In an embodiment a tube 19 is located in a hole 21 in a plate 17 and welding is effected by one electrode 10, with a conical face 11 to fit the tube end and another electrode 12 which straddles the tube 19 and having projections 14 with contact faces 15 which engage the plate 17 near the tube 19. A U-shaped insulating member 16 partly surrounds the tube 19 to prevent contact with the electrode 12.

Title: Means for simultaneously determining the volume, the weight and the density of granular and other materials
IPC: G01G13/00
Filed: 1935-11-04
Abstract: 445,520. Automatic feed weighers. SOC. DES COMPTEURS VOLUMETRIQUES, 110, Boulevard Sebastopol, Paris. Nov. 4, 1935, Nos. 30404 and 30405. Convention dates, Jan. 3 and June 29. [Class 143] An apparatus for automatically delivering measured volumes of granular material and indicating the weights and densities thereof comprises a weigh hopper 5 surmounted by an independent compensating hopper 16 in such a manner that the weigh hopper when full may descend alone and automatically indicate the weight and density of its contents. In the operation of the apparatus, commencing with the mechanism in the position shown in Fig. 1, the granular material passes from a feed shoot 59 through the compensating hopper 16 and into the weigh hopper 5. The compensating hopper and the weigh hopper are independently supported on the ends of counterweighted beams 2, 18. When the weigh hopper is full the material accumulates in the compensating hopper until the total weight causes the two hoppers to descend, whereupon the compensating hopper is arrested by the abutment of its beam against a pick-up weight 22, Fig. 2. During the downward movement a stationary abutment 52 trips a toggle linkage 49, 47 connected to a threearmed lever 42, 43, 44 pivoted on the compensating hopper and allows a spring 54 to close the bottom of the compensating hopper by means of a door 45. A stop 44<1> at the same time allows the feed gate 56 to reduce the feed. Owing to the tilting of the scale beam a sliding weight 8 supported thereby moves to the hopper end of the beam and causes a further descent of the weigh-hopper free from the compensating hopper. The weigh-hopper end of the scale beam descends upon a knife-edge 10 connected by a link 11 to a pendulous lever 12 which brings the system to equilibrium and indicates on a dial 13 the weight and density of the material in the weigh hopper. When the weight of material accumulating in the compensating hopper 16 is sufficient to overcome the pick-up weight 22 a rod 39 pivoted to the compensating hopper unlocks toggle levers 33, 30 and allows the discharge gate 27 to open and deliver the contents of the weigh hopper. During the subsequent rise of the weigh hopper the mechanism returns to the position shown in Fig. 1 and the operation is repeated. In a modification the sliding weight 8 is replaced by a weight 8<a>, Fig. 4, secured to a pivoted fork 7<a> actuated by a pin 62 on the beam. In a further modification, Fig. 5, the weight 64 is dropped from the scale beam on to a shelf 67 by contact with a stop 66 and is picked up again on the return of the beam. In a further modification, Fig. 7, the rocking of the beam closes electric contacts 75 and an electromagnet 70 draws the weight 64 off the beam, the weight returning by gravity when the contact re-opens. Specification 409,629, [Group XXIX], is referred to.

Abstract: 681,335. Sliding clasp fasteners. TALON, Inc. Dec. 13, 1950 [Jan, 12, 1950], No. 30433/50. Class 44 The bottom end connector of a sliding clasp fastener is in the form of a slider so that the fastener may be opened from the bottom if necessary, the arrangement being such that when both the connector and the main sliding clasp are in their lowermost positions the tapes may be completely separated. The elements 2, Fig. 10, on the tapes 3 are of the symmetrical type so that they may open and close in either direction. Pins 12, 13 secured to the bottom of each tape are adapted to be received in a Y-shaped channel 25, Figs. 6, 7, the end connector 20 which comprises spaced flanged plates 21, 22 connected by a wedge piece 23. A forked projection 16 on the pin 12 is adapted, when the connector is in the bottom position, to embrace a finger 17 on the pin 13, preventing lateral movement and to abut the end element 2b on the other tape. A portion 18 on the pin 13 is also arranged to engage under a shoulder 19 on the pin 12 to prevent relative. longitudinal displacement of the pins. The connector 20 mav be locked in the lowermost position or in any position on the tapes by a projecting finger 33, Fig. 7, adapted to engage in an opening 37, Fig. 10, in the pin 12 or between fastener elements. The finger 33 is carried on a plate 32, Fig. 6, housed in a recess 28 in the back of the connector, the plate 32 being secured to the end of a slidable pin 34 passing through the wedge 23 and formed with a button 35 at its outer end. A spring 36 under the button biases the finger 33 to the locking position from which it is moved by pressure on the button 35. The rear side of the connector is formed with an upstanding wall 26 providing a locating socket for the slider 41 when in the bottom position. In this position the pin 13 may be drawn out of the connector and slider to separate the tapes completely. The pin 12 is formed with an enlarged end 38 which prevents the connector leaving the associated fastener tape. Specification 624,334 is referred to.

Title: Apparatus for detecting and extracting a telegraphic channel in a frequency multiplex transmission system
IPC: H04J1/14
Filed: 1973-06-27
Abstract: 1417258 Digital transmission; testing COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 27 June 1973 [27 June 1972] 30583/73 Heading H4P An apparatus for identifying which of a number of multiplexed particularly frequency multiplexed channels carry telegraphic signals comprises cyclically connecting at high speed a first detector, which after giving a positive indication of signals, connects a second detector operating at relatively low speed to confirm the test of the first detector. The frequencies comprising the multiplex are each transposed in the apparatus to a common frequency band for testing.  As data transmission on any channel is by FSK, a relevant tone on such channel will be at one but not both of two frequencies, i.e. Fo + 30 Hz, hence a terminal S, connected cyclically to each channel passes signals through narrow pass band filters 22, 23, through threshold detectors 24, 25 and clipping circuits 26 to an exclusive OR 28 giving a 1 output at T if a single tone, but not plurality, of appropriate frequency if present. The signal on T arrests the stepping mechanism (illustrated diagrammatically in Fig. 1, not shown) for a further test to be performed by apparatus as shown in Fig. 3.  The signals from S are also passed through a band-pass filter 32 tuned to Fo30 Hz, transition detector 32, 10 millisec. delay 33, provided to achieve a steady state after transition and'a modulo 4 counter 34 which is set'to zero by a start signal X1. The first transition count causes a switch 35 to close, passing a signal Z through discriminator 31 to first memory 37. The third transition causes switch 36 to close and signal Z to be passed through to second memory 38, both of which may comprise lowloss capacitors, the output from which passes to a comparator 39 the output from which reaches threshold detector 40 and inverter 41. If the signal Y is less than the threshold of 40, a 0 is applied to inverter 41, which, if gate 42 is primed by the third stage of counter 34, opens a gate 43 passing Z to 44. The interval between start and stop signals is 120 milliseconds hence a reference delay time of approximately 125 milliseconds is provided by resettable monostable circuit 46 set by X1 or reset by X2, and an "end of measurement" signal is emitted in the event of no transitions but if a transition occurs during the 125 millisec. delay then the monostable remains set. An "end of measurement" signal is also developed through OR 47 when stage 3 of the counter is activated.
