Title: Process for fabricating reactive metal elongate products
IPC: B21C23/22
Filed: 1970-12-04
Abstract: 1370616 Making reactive metal products, extruding YORKSHIRE IMPERIAL METALS Ltd 7 Jan 1972 [4 Dec 1970] 57761/70 Headings B3A and B3P A method of making a reactive metal elongate product such as tube, rod or wire, comprises electrodepositing on a bloom or billet of the reactive metal a coating of a ductile metal, which on heating forms with the reactive metal no eutectic composition having a melting point at or lower than the temperature of extrusion of the bloom or billet, diffusion bonding the reactive metal and the coating, either prior to or during an extrusion step by heating the bloom or billet and the coating either to a temperature at which a diffusion bond is formed or to extrusion temperature, extruding the bloom or billet to form an extrudate and cold working the extrudate to form the elongate product. Reactive metals are those which react readily with the atmosphere and with tools whereby galling occurs, e.g. titanium, zirconium and their alloys, while the ductile metal may be copper, nickel or silver. A thin first layer, e.g. 0À001- 0-005 inch, is electrodeposited on the bloom or billet and then a second, considerably thicker layer is deposited which may be of a different metal to the first layer. Alternatively the second layer may be applied as a can which totally encloses the bloom or billet.

Title: Method and apparatus for transmitting and receiving mechanical waves
IPC: G10K15/06
Filed: 1967-12-22
Abstract: 1,216,488. Generating acoustic waves. SOC. NATIONALE DES PETROLES D'AQUITAINE. 22 Dec., 1967 [28 Dec., 1966], No. 58373/67. Heading H4D. An acoustic wave of predetermined waveform, for transmission into a dispersive medium whose structure is to be explored, is synthesized by generating a train of impulses of like polarity, the envelope of the train being the predetermined waveform. In the Fig. 2 embodiment, impulses are generated by repetitive triggered discharge of condenser bank 19 through sparkgap 30. The bank 19 is charged from voltage source 25 via step-up transformer and rectifier unit 24 and connections 29a, 29b of a rotary bridging switch 28. For discharging the bank 19, voltage is applied from source 25 to AND gate 27a via bridged contacts 26b, 26c of switch 28 in the intervals between charging periods, and reaches the trigger input of a pilot discharge device 27 if a control signal from tape 2 is present at second input of gate 27a. Several spark gaps 30 and banks 19, together with their associated charging, discharging and gating circuits, are controlled from further tracks on tape 2 such that two or more discharges can be made to occur in phase at selected times whereby the envelope of the impulse train can be shaped as desired. For seismic exploration on land the spark-gaps 30 are located in a waterfilled cavity in the ground; for marine seismic exploration they are supported by a ship. One or more geophones detect the subsurface reflections of the acoustic wave and the geophone outputs are recorded for subsequent signal processing, e.g. for optical cross-correlation with the transmitted acoustic waveform to determine propagation times. Examples of suitable transmitted waveforms are given. In an alternative embodiment (Fig. 1, not shown) the rotary switch 28 and AND gate 27a are eliminated and the control signal on tape 2 is used to trigger one or more pilot discharge devices (11, 18) coupled to respective condenser banks (12, 19) and spark gaps (13, 20). The control signal also triggers, via delay circuits (14, 21), thyratrons (16, 23) for applying charging current to the condenser banks (12, 19).

Abstract: 1335840 Weighing system for conveyer BROOKHIRST IGRANIC Ltd 22 Dec 1970 [22 Dec 1969] 60945/70 Heading G4H A weighing system for a conveyer 6 comprises a sensor 10 preferably of a variable coupling transformer type, to give a D.C. voltage of a magnitude proportional to the instantaneous weight of the conveyer, and a second sensor 14 to provide a D.C. pulse train, the frequency being indicative of the speed of the belt, each pulse causing a pulse to be admitted from the circuit 22 of a constant width and in synchronization with a clock pulse train generated at 20, these latter pulses gating the voltage from 10 to charge an integrating capacitor in the circuit 26. The sensor 10 is driven by a sinusoidal input from oscillator 18 which also provides the input to the clock pulse generator 20 and which is also taken to the circuit 26 to discharge the capacitor when the voltage across it is above a threshold level, a clock pulse train corresponding to those half cycles used in the discharging process being emitted by the circuit 26, the frequency of which is proportional to the product of the instantaneous magnitude and velocity of the weight on the conveyer. This pulse train is gated at 32 and at 44 and 52 after being frequency divided at 40, 42 to counter 30 to give a running aggregate of the weight transported. The pulse train is also gated at 34 to a frequency to D.C. voltage converter 56, and then to a display meter 38 or to an analogue controller 58, or recorder 60 or computer 62. A digital voltmeter may be employed to supply signals to digital instruments 64. Calibration mechanism.-The apparatus also comprises a frequency divider 68 having input from the circuit 22 to provide one pulse per foot of conveyer movement the pulses to be gated at 76 to a count down counter 74 preset to a desired count. A manual switch SWC is placed in its calibrate position CA which applies a +24 V D.C. to a monostable 72 which is triggered by the leading edge of the first pulse from 68 to enable gates 76 and also gates 52 to decrement counter 74 with the pulses from 68 and increment counter 30 with pulses from 26. The monostable stays in this condition until the D.C. is removed by a switch activated by counter 74 upon its reaching zero. The apparatus is calibrated at zero with no load on the conveyer and at a known weight using test weights, and according to the readings on the counter 30, potentiometers 26a and 26b of the integrating circuit 26 are adjusted. It is stated that such adjustments are independent of each other.
