Abstract: 766,467. Cemented pile fabric. FABRIC DEVELOPMENT CO., Ltd. June 22, 1955 [June 28, 1954], No. 18890/54. Class 142 (4). In making pile fabrics by applying a backing coated with an adhesive to pile material temporarily supported in a consolidating medium, as described in Specifications 588,548, 611,927, and 719,465, the backing is applied by light pressure to exposed pile ends so that an air space exists between the adhesive and the consolidating medium. Slabs of alginate 1 supporting the pile material 2 and carried by a conveyer 3, pass beneath a revolving wire brush 4 which spreads the exposed pile ends and thence through a hot air drier 5. Rollers 6 pack the slabs close together. A web of hessian or cotton, or nylon fabric, having a thin coating of polyvinyl chloride 14 applied by a doctor 11 is lightly pressed by a roller 13 against the pile ends and leaves an air gap 15 (Fig. 3) between the adhesive and the slabs 1. The fabric so formed is passed under a metal skid or rollers heated electrically, or into a hot air chamber 16. Rotary hammers 19 remove the alginate and the fabric is passed into a washing and rinsing machine 20, 21 and through a hot air drier or final curer 22. In an alternative embodiment, the slabs 1 are turned upside down between two conveyer aprons at a point between the drier 5 and the rollers 6, and are fed on top of the coated hessian or other fabric, the weight of the slabs being sufficient to press the pile tips into the adhesive and leave the air spaces 15. The hessian or other fabric can be coated with adhesive by passing it over a licking roller operating in a trough or by spraying.

Title: Seismic detection system
IPC: G01V1/22
Filed: 1975-05-07
Abstract: 1466527 Acoustic receiving system WHITEHALL CORP 7 May 1975 19105/75 Heading G1G When signals from a capacitive type of acoustic transducer are to be conducted via a pair of twisted ungrounded conductors to a remote signalprocessing point, the loading effects of the shunt capacitance provided by the conductor pair are minimized by arranging for the conductor pair to feed a differential charge amplifier, and the effects of spurious signal pick-up on the conductors are minimized by cancelling common mode signal components in the amplifier output. In the Fig. 3 circuit signals from a hydrophone T or array of hydrophones, e.g. in a seismic streamer, are fed over conductors with distributed resistance R1 and capacitance CX to the inverting inputs of op-amps. A1, A2 which, by virtue of feedback capacitors C2, C2' act as charge amplifiers. The feedback action holds both inverting inputs at the same potential, i.e. ground, hence no voltage can appear across CX to distort the frequency or phase of the hydrophone signals. Difference amplifier A3 further amplifies the charge amplifier outputs and rejects common-mode signal components. Further details of the Fig. 3 schematic circuit are given in Fig. 4 (not shown). In a modification, Fig. 7 (not shown) a single op-amp constitutes the differential charge amplifier.

Abstract: 355,874. Control of several motors. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. June 24, 1930, No. 19207. Convention date, Aug. 9, 1929. [Class 38 (iii).] A number of motors are automatically successively started, each motor being run up to normal speed before the starting operation for the next is commenced. The first motor a1 is started by the closure of a self-maintaining contactor b1 consequent to the operation of a pushbutton d. At the same time a motor i is started which drives a controller drum k to close the circuit of the coil e2 of a contactor b2, so that the second motor a2 is started after a time interval. The remaining motors are successively started in a similar manner. In Fig. 2 (not shown) a resistance which is gradually short-circuited is introduced into the rotor circuit of each motor in turn. Alternatively a starting transformer may be used. A hand-regulated resistance may also be introduced into the rotor circuits for speed control. The successive starting may be regulated in accordance with the motor current, and motors with star-delta switches may be similarly controlled.

Title: Improvements in time division multiplex communication systems
IPC: H04J3/10
Filed: 1948-07-16
Abstract: 656,023. Multiplex pulse signalling. RADIO CORPORATION OF AMERICA. July 16, 16, 1948, No. 19213. Convention date, July 16, 1947. [Class 40 (v)] The pulses of a time division multiplex system are given sloping overlapping sides by passage through a pulse widening filter, in order to reduce the bandwidth which they occupy, and a cross-talk balancer circuit is provided at the receiver. The interleaved channel pulses, which may be amplitude or duration modulated, are passed through a band-pass filter, which may be a low-pass filter; before modulating a radio transmitter in amplitude or frequency. In one form of receiver, a portion of the output from the radio receiver 18, Fig. 3, is passed through amplifier 36 to the multiplex equipment 24. Another portion of the output is derived from a tapping on potential divider R31 connected across the radio receiver output and fed through a delay line 34 and inverting amplifier 35 to the input of equipment 24. The delay line 34 provides a time delay equal to one channel period, and the attenuator R31 and adjustable terminating resistances R32, R33 are set so that cross-talk in one channel due to the preceding channel is just cancelled out by the energy arriving over the delay line. In order also to reduce cross-talk in the second channel removed, resistance R33 may be adjusted to produce a mismatch of such a value and sign that energy reflected back towards resistances R31, R32 balances out this undesired cross-talk at the input of amplifier 36. In order to reduce cross-talk in channels due to energy from succeeding channels, the main signal branch may contain the delay line and that conveying the attenuated balancing signals having no delay, Fig. 4 (not shown). In another form of receiver, the output from radio receiver 18, Fig. 5, is fed direct to the multiplex equipment 24 over conductors 105 across which is shunted a delay line 104, connected thereto through attenuator 114, R101, R102 and terminated at the other end by adjustable resistance R103. The line is half the electrical length of line 34, Fig. 3, and the polarity and amplitude of the balancing energy fed back into circuit 105 after reflection at the termination R103 is determined by adjustment of the latter. Specification 605,128 is referred to.
