Title: Electromagnetic flush control apparatus for a flush toile
IPC: H03K17/95
Filed: 1975-12-23
Abstract: 1509600 Automatic cistern flushing devices YEE KYAR UN 23 Dec 1975 52690/75 Heading E1C [Also in Division G1] In an automatic flush control circuit for a toilet a capacitor 14 is caused to charge when a body is near to or on the toilet seat and discharge when the body leaves the seat to trigger an SCR 15 and energise an electromagnet 17 which causes the cistern to flush. A toilet seat is provided with a conductive loop 1, Fig. 3 (not shown) coupled by means of a screened cable 4 to the input of a low frequency amplifier 3. When a body sits on the seat a voltage is induced in the inductive loop 1 which voltage after amplification is coupled via transformer 8 and diode 10 to transistor 11 to turn the latter on. When transistor 11 conducts, a relay 12 is energised to cause the movable contact member M of a switch to move into contact with contact A so that capacitor 14 can charge from the V cc <SP>+</SP> supply via R1. When the body leaves the seat and the induced signal in loop 1 ceases, transistor 11 becomes non-conducting and relay 12 is de-energised so that the movable contact member M moves to contact contact B. Capacitor 14 now discharges through resistor R3 to the gate of SCR 15 to trigger the latter and so complete the energising circuit of electromagnet 17. Electromagnet 17 thus attracts its solenoid armature 18 attached by a string 21 to cistern flush lever 23 so that the latter causes the toilet to be flushed.

Abstract: 1,156,589. Monopulse radar. HOLLANDSE SIGNAALAPPARATEN N.V. 21 Nov., 1967 [22 Nov., 1966], No. 52955/67. Heading H4D. The Specification describes an amplitude comparison monopulse autotracking radar wherein by operating only on doppler frequency shifted echoes it is ensured that only moving targets are tracked. A four horn radar antenna 5, energized by pulse transmitter 1, produces azimuth and elevation difference signals AB and #E and sum signal # on lines 10, 9 and 11 respectively and receiver 4 produces corresponding IF signals: #E IF  = [(a+b) - (c+d)] sin W i t+[(a+b) - (c + d)] sin (w i Œwd)t #B 1F  = [(a + c) - (b + d)] sin W i t+[(a+c) - (b +d)] sin (w i Œwd)t #IF = [(a+b+c+d)] sin W i t + [a+b+c+d) sin (w i Œwd)t where the first halves of each equation represent the return from fixed clutter, and the second halves the return from the moving target. The three signals are detected in respective phase sensitive detectors 24, 23, 22 by the output R sin Wit of coherent local oscillator 31 to give: #E D  = [(a+b) - (c+d)] + [1+sin W i Œwd)t] (1) #B D  = [(a+c)- (b+d)][1+sin(wiŒwd)t] (2) #D = [a+b+c+d] [1+sin (wiŒwd)t] (3) To track the target in range, a gate pulse from a generator 3 forming part of an auto tracking system (not shown) gates open boxcar circuits 27, 26 and 25 respectively receiving the three detected signals. The clutter (D.C.) contents in the outputs of the box car circuits are removed by Doppler filters 28 and the resultant Doppler frequencies difference signals:- #E d  = [(a+b) - (c+d)] [sin (W i Œwd)t] #B d  = [(a+c) - (b+d)] [sin (w i Œwd)t] are detected with reference to the sum Doppler frequency signal #d = [a + b + c + d] [sin (w i Œwd)t] in phase sensitive detectors 37 and 38. The outputs of the detectors are the normalized azimuth and elevation tracking signals. (a+c) - (b+d)/(a+b+c+d) and  (a+b) - (c+d)/(a+b+c+d) and are applied to tracking servos 15 and 16. To overcome " blind speeds " a pulse repetition frequency control 40 may be used.

Abstract: 1528917 Doppler flowmeters DETECTRONIC Ltd 28 Nov 1975 [11 Dec 1974] 53598/74 Addition to 1415839 Heading G1G In a method of monitoring fluid-flow in a conduit, the output of the Doppler frequency difference proportional to flow speed of a Doppler flowmeter using continuous wave generation is processed by a variable divider 18, and a fixed divider 22 to give a reading corresponding to some flow parameter of interest e.g. flow speed. For a given Doppler frequency shift the mean current to indicator 28 can be varied by controlling the duty cycle of the pulse generator 32. The divider 22 and switch 40 provide for high and low speed ranges on lines 38 and 36 respectively to be displayed on the indicator 28. The instrument is first calibrated using water at a known speed under, for example turbulent flow conditions when divider 18 is arranged to give an approximate reading, fine correction being made by varying the duty cycle of pulse generator 32. The divisor used in divider 18 is altered when either the liquid or the flow type is altered. Indicator 28 may be replaced by a computer which may also incorporate the functions of a divider 22 and may also yield volume or mass flow information. In apparatus claimed for the method Fig. 3 (not shown) a further adjustable divider (52) is fed from line 36 to output amplifed pulses to a resettable digital recorder (60) functioning as a cumulative volume or mass flow indicator. For hot liquids the transmitter-receiver assembly 4 may incorporate a glass stand-off (42), Fig. 2 (not shown).

In one arrangement, Fig. 3, a matrix of display cells 30 having anode electrodes 70 connected to a driver 140 and cathode electrodes 80 connected in groups of three to drivers 120A, 120B, 120C, is provided at each end with a column of cells 90, the cathodes 100 of which are connected in pairs to drivers 130E, 130F, 130G. With the anode driver 140 energized, the first cathode driver 130E is energized and the first cell 90E is turned on preferentially over the other cell 90E by a starter cell 131 located adjacent thereto. The drivers 130F and 130G are then energized in turn to step the discharge to a selected row, whereupon the drivers 120A, 120B and 120C are energized in turn to step the discharge to a selected column. By carrying out this procedure at a sufficiently high rate, a stationary but changeable message or character made up of selected cells may be displayed, or TV-type scanning can be carried out. Alternatively, once a cell has been turned on, the firing potential can be removed and the glow sustained by applying sustaining pulses as described in Specification 1,273,595. Since excited particles diffuse in two directions along the channels 110 from a discharging cell 90, an auxiliary cell (Figs. 4 and 5, not shown) may be provided in each row between a cell 90 and a cell 30 to ensure  that stepping is effected along the correct row.

Abstract: 1430486 Memory systems HONEYWELL INFORMATION SYSTEMS Inc 28 Nov 1973 [2 Jan 1973] 55264/73 Heading G4A In a data processing system in which a sectioned memory 102-2 (Fig. 1) is addressed from a memory address register 102-6 to read out data to a register 102-4, if an address does not correspond to a memory section present in the system an output signal is generated from checking circuits. As described, the memory is a core matrix memory comprising eight pairs of planes (Fig. 1A, not shown) the address bits being fed to X and Y decoders and X and Y selectors to generate read and write command signals for the appropriate storage location. The read command signals for each plane are fed to one of a pair of AND gates in associated logic circuits 300-10, 300-11, 300-12 (Fig. 2a). A memory plane present signal is fed to the other pair of AND gates this signal being at its "1" level if the plane is not present and rippling through the checking circuits of lower address planes to generate the signal X1MCK00=0 if an addressed plane is not in the system. This controls a test flip-flop 102-10, the state of which is tested during normal processing if a parity error signal is generated by a parity check circuit 120-12, the attempted read-out of a non- existent memory location automatically producing a parity error. Fig. 2b (not shown) represents a second embodiment of checking circuits with ripple and Fig. 2c (not shown) represents a third embodiment of checking circuits in which the outputs of all the circuits are connected in common to the input of the bi-stable. Diagnostic routine.-This may be effected either in response to an error condition or as part of the initialization routine. In the latter case a control store 120-2 storing microinstructions generates a command to zeroize register 106-2 and bit counter 102-2 feeding memory address counter 102-6. All memory locations are then addressed four times to check addressing, reading and writing, first with an all zero bit combination, then with an all one bit combination, thirdly with the lower half of the memory address and lastly with the higher half. During these operations the parity check circuit is inhibited. Then the storage locations are addressed to find the address of the highest memory location present by deter-  mining when the flip-flop 102-10 is not switched. The address then in the register 106-2, corresponding to the first absent memory location is transferred to a scratch pad section of memory 102-2 from which it may be subsequently fetched if for example processor 105 wishes to ascertain the amount of memory available.
