Abstract: 1,231,314. Unpacking. A. STICHHAN. 26 July, 1969, No. 37669/69. Heading B8C. Rows 5-8 of open-ended tubes are unpacked from a package 2 on a conveyer 1 and are transferred to a conveyer 3 by means of a row of holding fingers 9 which are reciprocated by a drive wheel 11 to enter and lift the tubes, pivoted about the axes of the drive wheel 11, extended to place the tubes over the conveyer 3, and retracted so that a comb 15 strips the tubes therefrom. The fingers 9 are mounted on a bar 9<SP>1</SP> having an extension which is attached to a rack 21 and is slidably received in a housing 51 pivoted on a shaft 23. The rack 21 is reciprocated by a wheel 22 which is rotated via a chain and sprocket linkage 27, 29, 31, 33, 35 by a pivot-arm 39 acted on by a cam 47 and connected to the chain 35.

Abstract: 1,232,187. Welding by fusion. FORD MOTOR CO. Ltd. 3 Jan., 1970, No. 347/70. Heading B3R. In electron beam butt welding, a secondary beam is used to smooth a rough underbead formed at a main welding beam exit. The secondary beam is of lower energy and more diffuse than the main beam. As shown, in the longitudinal butt welding of two halves of a tube 20, two beams 16, 17, respectively effecting left- and right-hand welds, have overspill portions 18, 19 respectively smoothing right- and left-hand underbeads. The beams are inclined and the workpieces are moved in the direction 21 so that the smoothing follows the main welding. When the open end of the tube is reached, the beam intensity is reduced to accommodate smoothing only. The two beams may be pulsed or cyclically interrupted to avoid their mutual hindrance, e.g. to avoid particle collision. In a similar arrangement (Fig. 3, not shown), two opposed beams are used to effect a circular weld between abutting tubes. When welding workpieces of varying thickness using overspill of a beam for smoothing, the welding parameters must be modulated during the process.

Abstract: 1,253,230. Transistor switching circuits; telegraphy; common mode signal rejection. MULLARD Ltd. 31 Dec., 1968, No. 61957/68. Heading H3T, H4P and H4R. A digital receiver comprises a first long-tail pair T1, T2 connected to receive its input from a transmission line and a second long-tail pair T9, T14 supplying the current to the first (via T9) and controlled by a connection to the centre tap (labelled " overide point ") of the cable termination R1, R2 so as to disconnect the tail current in the event of the transmitter being disconnected and determine the output state of the receiver. The two input signals are constituted by a current to one or other of the input terminals I/p1, I/p2 and this flows partly in diode D2 and partly in a circuit T12, T13. While D2 conducts the emitter of T12 is below ground and the transistor is saturated, so that T13 is off. If the cable breaks, D2 cuts off and D4 begins to conduct, raising the potential of T12. The base is clamped and T12 cuts off, allowing T13 to conduct, T12 and T13 forming a regenerative bi-stable circuit. T13 carries a larger current than T12 so that by the potentive of the overide point rises rapidly and the line base of T4 is carried above the reference voltage applied to the base of T9. Accordingly, the tail current for the input amplifier T1, T2 is diverted to T14 and so forces the output circuit of T1 and T2 into a corresponding state. The input amplifier has its collectors caught by T10, T11 which are biased by D1 and the amplifier feeds respective output amplifiers T3- T5 and T6-T7. A strobe pulse may be applied at I/p3 and this acts on T14 in the same manner is a cable breakage. (For Figure see next page.)

Abstract: 1308640 Compandor systems GENERAL ELECTRIC CO Ltd 9 Aug 1971 [7 Aug 1970] 38131/70 Heading H4R  In a compandor system in which the degree of compression applied at the transmitter is signalled to the receiver to control the degree of expansion to be applied, the information is conveyed by the frequency difference between two tone signals. As shown an incoming speech signal is split at 3 and applied to a compressor circuit 14 and a control circuit. In the control circuit the signal is applied to a variolosser controlled by a rectifier 8 to provide a 2 to 1 compression of a speech signal, in dB. The rectifier output is also applied to further variolossers 15, 17 in the compressor circuit, each of which gives a compression of 2 : 1, in dB, on the input signal so that the output of the compressor is substantially constant. The rectifier output is also applied, via a logarithmic amplifier to modulate the frequency of an oscillator 10 over a range 2840 to 2960 Hz. The variable frequency oscillator output is added to a fixed frequency signal of 2650 Hz in combiner 12 and the resulting signal combined with the compressed speech signal in combiner 22. A delay 13 is provided in the compressor input to allow the control signal to reduce the gain of the compressor before an increase in signal reaches the compressor. A second delay 20 is provided to compensate for transmission delay difference between the speech signals and the control signals. A limiter 19 can be provided to limit impulsive interference &c. At the receiver the two tone signals are separated out by respective filters 27, 28, and applied, via limiters to discriminators 31, 32 to provide voltages dependent on the tone frequencies. A voltage comparator determines the difference voltage to provide a control voltage for the expandor 42, through a filter 35, which removes the tone frequencies, a fast acting fading regulator 36, and an optional delay 41.
