Patent GB-1296132-A (GB)
IPC: H04B3/20
Filed: 1970-02-23
Abstract: 1296132 Echo suppressors WESCOM Inc 23 Feb 1970 [25 Feb 1969] 8626/70 Heading H4R In an echo suppressor an attentuation pad 45 is inserted in the transmit channel 28 on detection of a signal in the receive channel 32 exceeding a predetermined threshold value. In addition the signal in the transmit channel 28 is compared with the average signal in the receive channel and if the signal in the transmit channel is greater a "break in " circuit 56 is operated to remove the attenuator from the transmit channel and insert an attenuation pad of lower value, e.g. 6 dB, in the receive channel, to allow breaking in while still reducing echo to a nominal value. As described the received signal is applied via a 300 to 3000 Hz, filter 52 to a rectifier circuit including the operational amplifiers 143, 153, and diodes 144, 145, which provide full wave rectification of the low level received signal. The output from the rectifier circuit is applied to a further operational amplifier 175 provided with a reference potential on its other input as a comparison potential. The output from the amplifier 175 is applied, when it exceeds the reference potential, to charge up capacitor 211 which is in a fast charge slow discharge circuit to provide a hang over on the suppressor operation. Charging of the capacitor causes operation of a trigger circuit including transistors 201 and 202 and, via amplifier transistors 181, 182, the insertion in the transmit channel of the attenuator comprising the series connected transistor 331 and shunt connected transistor 332. In addition to comparison with the reference voltage in amplifier 175 the output of the full wave rectifier 53 is also fed to a peak detector 55 to provide a signal on line X, indicating the average peak level of the signal in the receive channel, which is combined with the filtered signal in the transmit channel 28 on line W and applied to a comparator 261. When the transmit channel peaks exceed the average peak level of the receive signal the comparator delivers a signal which triggers a driving circuit 262 and switching circuit 265. The switching circuit, via lead Z inserts a small attenuation in the receive channel by making diodes 46 conductive, and at the same time a transistor 221 connected to the trigger circuit in the transmit channel attenuator control system is turned on to ensure the immediate removal of the attenuator from the transmit channel. The insertion or removal of the attenuator in the receive channel is arranged to take place slowly, to avoid transients, by the inclusion after the switching stage 265 of a capacitor 296 and transistor 293. Hang over of break in is provided by capacitor 301. Switches 226 and 317 are provided to inhibit the operation of the suppressor and break in circuits for adjustment of circuit gains, or use of the apparatus for data transmission &c.

Filed: 1969-01-24
Abstract: 1301273 Endless conveyers UNITED GLASS Ltd 3 April 1970 [24 Jan 1969] 4095/69 Heading B8A Articles on a continuously driven endless belt 6 are formed into groups by the plungers of solenoids 14, 16 controlled by an articleengaging microswitch 22. To permit variation of the number and height of articles in each group, the distance by which the solenoids are separated and their height above the conveyer are adjustable. The switch 22 is also adjustable horizontally and vertically. In operation, solenoid 16 is energized due to bottles contacting the switch 22 and when a bottle comes to rest opposite the switch, the switch causes solenoid 14 to be energized, the solenoid 16 is de-energized and a group of bottles passes downstream. When there is a sufficient gap between this group and the solenoid 14, the solenoid is de-energized and bottles pass normally along the conveyer. The group having cleared the solenoid 16, this is again energized and a new grouping operation is initiated. If for any reason the switch 22 fails to function after a certain period of time an over-ride timer causes the solenoid 16 to be de-energized and the bottles are allowed to pass. The switch 22 may alternatively comprise a photo-electric detector, a capacity detector, an acoustic detector or an ultrasonic detector. An electric supply and control circuit is described and illustrated. Conveying rollers may be associated with the conveyer belt.

Abstract: 1319604 Multiple push-button switches; electric motor controllers DYNAMICS CORP OF AMERICA 25 Aug 1970 40835/70 Heading H1N [Also in Division H2] In a multiple push-button switch assembly in which push-rods 22a, Figs. 8, 10, of the buttons actuate one or more of a plurality of sliders as 32D1, 32M associated with predetermined combinations of switch actuators 30D, 30M, separate control means for actuation of further switches in series with the switch combinations on depression of selected push-buttons is provided. The arrangement is particularly applied to a push-button variable speed control for an electric motor, Fig. 5 (not shown), in which different speeds are obtained by closure of selected switches (2)-(7) to obtain series or parallel combinations of field coils (B)-(E). The push-buttons 110, Fig. 4, are arranged in pairs on cross-shaped sliders 21 movable in slotted guides 72 against the action of returnsprings 18 to operate the sliders 32 via projections 66 on push-rod parts 22. Selected spring blade contacts 38 thereby open or close circuits with fixed contacts 34 each comprising one of the switches (2)-(7) of Fig. 5 (not shown). Either push-button 110 of each pair closes the same switch combination via the sliders, but each push-button pair is associated with a slide switch 96, Fig. 3, for shunting a further motor field coil (A), Fig. 5 (not shown), and a series diode 27 to connect the field coil (B) directly to the supply line (L1). Since this slide switch 96 is closed only by a common rocket 92, 94 when any of the left hand push-buttons is depressed this gives a stepped-up speed range for all the left-hand buttons. The sliders 32D1 may have differently shaped recesses 52D, 52M with different cam-shaped sides 50, 58 to provide delayed or reciprocated motion to the selected sliders. The sliders 32M, further have grooves 51 permitting relative movement with the sliders 32D, some of which may be riveted together as at 55 to provide a common movement. The camming faces 46D, 46M for engaging the switch contacts 30D, 30M may also have elongated flats as 46M whereby the main switch (8), Fig. 5 (not shown), is opened before the other switches (1)-(7) are changed and closed afterwards, whereby only the main switch (8) is operated under current carrying conditions and is therefore the only switch requiring a high rating for circuit breaking.

Abstract: 1344831 Plate heat exchangers ASSOCIATED ENG Ltd 19 April 1971 [4 March 1970 11 Jan 1971] 10478/70 and 1314/71 Heading F4S A flow passage in a heat exchanger is formed by a stacked series of wall-forming members and apertured, heat-conducting, plate members all bonded together by an adhesive providing a thermally insulating barrier and reducing heat flow between adjacent members of the assembly. The apertures in successive plate members may be relatively staggered. The plates may be of copper or aluminium and the wall-forming members of a thermally insulating material, of a plastics material or of metal. Thermally insulating washers may be interposed between the wall-forming and plate members. As shown, two fluid passages are formed by a stack of plates 21 and rings 25, 28. When assembled, perforated parts of the plates extend across the fluid passages, and the rings are aligned with imperforate parts of the plates. In other arrangements (Figs. 2-4) applicable either to cross-flow or parallel flow heat exchangers, individual plate areas covered by groups of the apertures and outlined by the wallforming members are hexagonal or sectorshaped. A cross-flow heat exchanger is described, Fig. 5c (and Figs. 5a-5b) in which sheet members with two sets (62, 63) of apertures therein are stacked alternately with wallforming members (65). These latter co-operate with plane portions (64) of the sheets to form flow passages (66) with the apertured sheet portions (62) extending across the passages. The other apertures (63) comprise louvres some of which may be pressed out in the opposite sense to others from the sheet material. In another cross-flow heat exchanger described (Figs. 6a, 6b) flow of one of the fluids is parallel to plate areas which may be apertured or not. The apertures when provided serve in this case as turbulators.
