Abstract: 1370314 Welding by fusion LONGYEAR CO 21 Oct 1971 [26 Oct 1970] 49019/71 Heading B3R [Also in Division E1] In a drill rod having a steel body 11 connected by welds 32 to a pin 12 and a box 13 of higher grade steel, the ends of the body are tapered at 14, 15, the end of the pin adjacent the body is tapered at 21, 22 and the end of the box adjacent the body is tapered at 26, 27 prior to welding. Before machining tubular blanks for the box and pin to their final shapes the outer surfaces of the blanks are induction hardened except adjacent the ends to be welded, and subsequent to the machining the outer surface of the box is chrome plated at 31. The minimum internal diameters of the pin and box are smaller than the constant internal diameter of the body. The welding is effected by external application of heat and metal to form external and internal beads filling the groove formed by the surfaces 14, 27 and the groove, if any, between the surfaces 14, 26.

Abstract: 1,090,912. Transistor amplifier circuits; transistor pulse circuits. BALL BROS. RESEARCH CORPORATION. Dec. 9, 1964 [Jan. 23, 1964], No. 50210/64. Heading H3T. [Also in Division G1] Pulses from a photo-multiplier 28 (Fig. 3) are amplified by a linear preamplifier having negative feedback through a resistor 40. A fraction of the signal output of transistor 39, adjusted by a resistor 49, is fed back to the amplifier input via capacitor 46 and earth. Diode 47 provides temperature compensation for the transistor 30. Pulses from the preamplifier are fed through coupling capacitors 53, 54, to a pulse height discriminator. which generates pulses of constant amplitude when the voltage input exceeds a predetermined threshold. Pulses from the transistor 39 sufficient to increase the current in tunnel diode 55 to the peak point current or beyond, result in its switching rapidly to its high voltage state and in the transistor 59 switching on to give pulses of an amplitude limited by its saturation voltage. An inductor 58 acting as an R.F. choke allows a fixed delay before causing the diode 55 to switch back to its lower voltage state, when the pulses output is limited by a temperature compensated Zener diode 62. The pulses pass through emitter follower transistors 64, 65 and are converted into an analogue signal proportional to their frequency by a rate meter. This signal is fed to the base of a unijunction transistor 80 and when it reaches the peak point voltage of the transistor 80, capacitor 67 discharges into the gate of the S.C.R. 81 to activate a relay 82. The circuit is used in apparatus for measuring the thickness of the wall of a hollow container, (3 particles transmitted through the container wall being detected by the photomultiplier in connection with a scintillator and the ouput analysed to determine whether the walls are of the required thickness (see Division G1).

The gas then flows along the auger with the material, up conduit 19 to a cyclone separator 20 where material particles are recovered from the gas and through exhaust pipe 21. Some gas passes from the auger to the separator 20 up a branch conduit 23 and is replaced directly from the duct 27 through a conduit 25. Conduits 23, 25 are controlled by slides 24, 26 respectively to adjust the temperature in the auger tube. More than one conduit 25 may be provided to vary the temperature along the auger. Material is fed from a hopper 9 to the auger 2 by a feed auger 8, the material in the auger 8 preventing any leakage of gas. The material is discharged through a valve 13, e.g. of the rotary type, that prevents substantial loss of gas from the auger. The tube 1 is supported on side walls 14 which with the bottom of the tube 1 and the ground define the duct 27; the tube 1 may instead be supported by a channel member forming the duct 27 with the bottom of the tube 1.

The opposed ends of looped electrical leads 10 are gripped by pairs of grippers 12 carried on an endless conveyer. During the travel of the latter, the ends of the leads are stripped and crimp-fitted with connectors at stations 24. Further downstream, the upstream gripper of each successive pair of grippers, is released, and the loop is engaged by one of a number of members 55 carried by an endless chain (46) (Fig. 2, not shown). This causes the lead to be combed out, and the other gripper 12 of the pair is then released to permit the lead to fall into a bin 40. The second gripper 12 is released by the action of a push rod 98 actuated by a cam 92. The latter is rotated by a rack and pinion mechanism 84, 86 driven by a linkage 68, 70 from a shaft 32.
