Abstract: 1347060 Air filter BUEHLER AG GEBR 26 Aug 1971 [28 Aug 1970] 40177/71 Heading B1T [Also in Division G3]  A filter apparatus for removing dust from air comprises inlet 5, filter hoses 2, cleaned air chamber 9 with cleaned air outlet 10 and scavenging air chamber 7 separated by baffles 6 and 8 from the dirty-air and clean air chambers. The filter hose interiors are connected to the clean air chamber by ducts 15 which are of such a diameter as to leave annular open ducts 58 between themselves and the edges of the filter hoses. These annular ducts connect with the scavenging air chamber 7 which is itself connected to a source of compressed air for feeding a reverse cleaning flow of air through the annular ducts 58 into the filter hoses. The annular ducts 58 may be closed by elastic diaphragms 60 when the latter are inflated by supply of compressed air to their interiors 57 by means of ducts 21 which connect the diaphragm interiors both to the supply of compressed air and also to a number of rapid-venting valves. The apparatus also comprises a number of fluid logic control elements which are arranged such that when the pressure difference between the clean-air and dirty-air chambers exceeds a predetermined amount, then automatically each filter hose is cleaned sequentially by a reverse flow of air. In each case the cleaning being effected by compressed air being supplied both to chamber 7 and to the diaphragm 60, the latter closing the annular duct 58, thus being followed by rapid venting of the interior of the diaphragm to allow the reverse flow of cleaning air into the tube. The rapid-action venting valves are actuated sequentially by a fluid logic element control system (see Division G3).

Abstract: 1344427 Controlling spin of vehicle wheels DAIMLER-BENZ A G 8 Sept 1972 [28 Sept 1971] 41839/72 Addition to 1267220 Heading G1N Apparatus for controlling the slip of the driven wheels of a motor vehicle comprises means for comparing the speed of a non-driven wheel with a proportion of the speed of a driven wheel, the proportion being determined by the vehicle speed, and controlling either the braking pressure or the engine torque in accordance with the difference. As shown, the angular speed of a driven wheel 3 and a non-driven wheel 1, both on the same side of a vehicle, are measured by tachogenerators 7, 5. A proportion of the signal from the tachogenerator 7 is tapped off by potentiometer 11, the proportion being determined by element 101 in accordance with the speed of the non-driven wheel 1, representing the vehicle speed, and compared in amplifier 9 with the signal from generator 5. If the difference exceeds a predetermined level, amplifier 9 sends a signal to OR gate 105, whose other input is a signal representing the acceleration of the driven wheel 3, obtained by differentiating the speed signal at 103. Similar apparatus on the other vehicle side feeds into OR gate 106. The outputs from gates 105, 106 are taken to an AND gate 21 and two NAND gates 22. If a signal is obtained from one OR gate only the appropriate NAND gate 22 operates through member 17 or 18 to relieve the brake 20 on wheel 3 or 4: if a signal is obtained from both OR gates, AND gate 21 operates a member 16 to reduce engine torque.

Filed: 1973-09-06
Abstract: 1394148 Substation equipment INTERNATIONAL STANDARD ELECTRIC CORP 6 Sept 1973 [11 Sept 1972] 41881/73 Heading H4K A push button impulse transmitter, which utilizes a latching relay for producing loop disconnect pulses under the control of an electronic decoding circuit, is powered by a capacitor that is charged over the line via the impulsing contact when this and the hook switch contacts are closed. The capacitor is connected in series with the shunt combination of a resistor and a diode, the latter being reverse biased during charging and forward biased during discharging, i.e. during dialling loop interrupts, so as to present a low internal impedance to the load. An appropriately biased transistor may replace the diode. With hook switch contacts Gs1, Gs2 closed, the line loop is maintained via contact S1 in the push button key block. When any key is operated, S1 opens so as to transfer the line loop to the Zener diode stabilized diode bridge D1-D4. If impulsing contact IC is not closed at this time, transistor amplifier T7, T8 is effective to energize impulsing relay IR so that a charging circuit for storage capacitor C5 is made. A network consisting of capacitor CR, resistor RR and diode DR produces a resetting pulse for a MOST logic decoding circuit M and clock C is started. The operation of the push button also actuates contact S2 which causes a contact-bounce blanking network CB, RB3 and transistor amplifier T3, T4 to bring-up offnormal relay ONR. The latter short circuits the speech network at its contact ONC. About 800 msec. after the depression of the button, the logic finishes decoding the digit value and via amplifier T5, T6 causes impulsing relay IR to generate the appropriate impulse train. During breaks in the train, capacitor CS in its discharge path via diode DS provides the requisite power for the circuit components.

Abstract: 1,090,557. Seaming non-metallic sheet material; strengthening edges. RENCO MARWELL S.r.L. Oct. 4, 1965 [Oct. 16, 1964], No. 41979/65. Heading B5K. Relief piping is obtained on sheets of thermoplastic material by inserting in a channel 5 running parallel to the longitudinal axis of a first electrode 4 a cordlike element 7 of synthetic plastics material having substantially the same thermoplastic characteristics as the sheets and of such thickness as to be held with slight constraint by the lateral edges of the channel 5, placing the sheets of plastics material between the electrode 4 and a second substantially flat electrode 1 towards which the electrode 4 presents its channel 5, and passing high frequency current through the electrodes 1, 4 so that when the electrodes have been moved relatively towards each other the superposed thermoplastic parts are fused into a single mass and the joined sheets are cut immediately beyond the join. In the embodiment shown, the lower electrode 1 is fixed and the upper electrode 4 is movable. One of the edges defining the semicircular-section channel 5 projects more than the other to form a sharp cutting edge 6 to cut the sheets immediately beyond the piping after welding. A sheet of insulating material (not shown) may be placed between the electrode 1 and the thermoplastic sheets to avoid the edge 6 coming into electrical contact with the electrode 1 during or after cutting. The invention is applicable to form a double-wall container by providing piping on the edges of four thermoplastic sheets, Figs. 5 and 6 (both not shown).

Abstract: 1,147,256. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 14 Sept., 1967 [17 Sept., 1966 (2)], No. 41990/67. Heading H4K. A plurality of channels carrying V.F. (e.g. dialling) signals are scanned in TDM manner and the results of the scanning are stored in a memory in respective sections thereof reserved for each channel. The contents of each section are then read-out at a much higher rate than they were written-in so as to effectively increase the frequency of the original VF signals whereby they can be analysed by BPF's having relatively large bandwidths and short transit times. This method is adopted because a centralized control analyzing the high frequency signals can monitor a greater number of channels carrying signals that last for a given time than could a control analysing directly the incoming VF signals. 2-out-of-6 VF signals having a minimum duration of 10 msecs. and occurring on channels S1 . . . Sn are sampled at a 5 kc/s. rate by scanner ZM and the results, after conversion into digital form, are stored in sections of a core store HSP pertaining to each channel. When each channel has been sampled 25 times scanning is stopped for one cycle and all the contents of HSP are read-out during this cycle, corresponding to a read-out rate of 5 Mc/s. Each section is read-out in parallel, via digital/ analogue converter DAW, low-pass filter TP (cut-off 5 Mc/s.) and band-pass filters BF1- BF6 (bandwidth 100 kc/s.), so that a 2 out-of-6 code is written into similar sections of a store (register) RSP. It is ensured that each code contains only two elements by means of a fault detector CU. If incoming signals occur in 2-out-of-8 code, they are analysed and then converted into 2-out-of-6 code by auxiliary filters BF<SP>1</SP> and converter CW. The above numerical data relates to a system having 20 channels. If the incoming signals have a greater minimum duration then the channels can be arranged in groups and each group then scanned and analysed repeatedly but in turn (Fig. 4, not shown). It is mentioned that the various scanning operations may be controlled by a stored program.
