Title: Electronic circuit comprising"d"and inverted"d"type flip-flops
IPC: H03K19/091
Filed: 1975-02-18
Abstract: 1503233 Electronic counters TEXAS INSTRUMENTS Inc 18 Feb 1975 [19 Feb 1974] 08291/77 Divided out of 1503231 Heading G4A [Also in Divisions G3 and H3] The description of an electronic watch is substantially the same as that of the parent Specification but the claims are directed to a circuit comprising a pair of D-type flip-flops which are cascade connected. The first is a D flip-flop as in Fig. 6a; the second is a conventional D flip-flop as in Fig. 6c. Such circuits are used in time counters of the watch (e.g. seconds counter 722a, Fig. 7).  Fig. 6a shows the D toggle flip-flop implemented in integrated injection logic (I<SP>2</SP>L) in which the outputs and D inputs are inverted so that the Q output is fed back to #D input. In injection logic a transistor is inherently in the conductive mode unless base drive, is removed therefrom such as by shunting the base drive to ground through the collectoremitter path of another transistor. In operation, assuming transistor T6 is conductive, the base drive for T 2 , T 3  is removed via respective AND gates. Assuming that the clock signal is low, the base drive for T 4 , T 5  is also removed via respective AND gates. Base drive for T 1  is provided via a respective AND gate when T 2  is OFF. When the clock signal goes high, T 2  goes OFF and T 5  conducts causing T 6  to go OFF which allows T 3  to conduct. When the clock signal goes low T 5  turns OFF and since T 6  is also OFF, T 2  will conduct. Conduction of T 2  causes T 1  and T 5  to turn OFF. When the clock signal goes high a second time, T 4  will conduct turning OFF T 3 . With T 3  and T 5  OFF T 6  will conduct turning OFF T 2 . When the clock signal goes low a second time, T 5  turns OFF and with T 2  and T 4  both OFF, T 1  will conduct. The cycle then repeats. A multi-collector I<SP>2</SP>L transistor may be used as a NAND gate and Fig. 6c shows a logic representation of the second flip-flop incorporating NAND gates.

Abstract: 239,251. Power, A. J. April 3, 1924. Teaching gunnery.-To enable gun crews to be trained without expenditure of ammunition, hydraulic or like mechanism is provided on a gun mounting for causing the recoil and run-out movements. As shown, a plate 4 fixed on the gun mounting carries inlet and exhaust valves 5, 5a, and valve-actuating gear whereby, when the firing mechanism is actuated, pressure is first admitted to a cylinder to cause the recoil movement and then, after a predetermined travel, the exhaust valve is opened to cause the run out. The valves are both connected to a floating lever 7<a> pressed down by a spring 14 to close the inlet valve ,and having a trigger 7 engaged by a lever 6 connected to the firing mechanism. When the firing mechanism is operated, the rear end of the lever 7<a> is raised and the inlet valve is opened. After a predetermined recoil movement, the trigger 7 is disengaged from the lever 6 by a recoiling rod 13, and the inlet valve is closed and the exhaust valve opened. The sound of discharge may be simulated by a rifle firing blank ammunition in a sound drum.

Abstract: 1499453 Alpha-numeric displays MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 28 Feb 1975 [28 Feb 1974 6 March 1974] 8552/75 Heading G5C [Also in Divisions C4 and G2] A nematic liquid crystal electro-optic "90 degree twist" cell is disposed between a linear polarizer 10 and a birefringent plate 12, the latter acting at some wavelength as a #/4 plate and having its axis at 45 degrees to that of the polarizer, so that circulary polarized light (CPL) of either hand may be selectively transmitted to a cholesteric liquid crystal layer 23 which selectively reflects light of a characteristic wavelength and hand of circular polarity. Light from layer 23 is then transmitted to an arrangement 12a, 11b, 10a similar to the arrangement 10, 11a, 12 but in reverse order for selectively transmitting CPL of either hand depending on the state of the twist cell 11b. If the two arrangements are set to pass CPL of opposite hand, substantially no light is transmitted. If they are set to pass CPL of the same hand, most light is transmitted if the hand is not that reflected by layer 23, and otherwise a coloured light beam is transmitted. The electrodes in one cell may be segmented, the other cell including only continuous electrodes. Operation of the other cell then alters the colours of the figure and ground defined by the first cell, e.g. to indicate a calculator malfunction, Fig. 4, (not shown). Alternatively the electrodes in both cells may be shaped with overlapping portions to provide multi-shade displays, Fig. 5 (not shown).

Title: Track-guided vehicle systems adapted for synchronised remote control
Inventor: DEMIDOFF BENJAMIN
IPC: B60L13/00
Filed: 1969-07-30
Abstract: 1,200,591. Railway systems. B. DEMIDOFF. 30 July, 1969, No. 8648/66. Headings B7L and B7N. [Also in Division H2] In a transport system for vehicles which are propelled over the tracks of the system by synchronous linear motors and controlled from apparatus at one or more control rooms the apparatus is synchronized to the progress of the vehicles by the use of a master alternating current or currents of frequencies related to that of the master current for both the propulsion of the vehicles and the actuation of the apparatus. Each vehicle comprises frame 8 supporting a load carrying portion 6 and permanent or electro magnets 5 which cooperate with wave wound element 2 [-see - Division H2), extending along the track, to propel the vehicle. Four sliders 10 support the vehicle on track 17 which includes turned over guide portions 18. The track runs in an enclosed tube 19. The propelling element 2 is trapezoidal shaped in cross-section to provide a degree of levitation for the vehicle. The vehicles can be switched from horizontal track to vertically ascending track giving access to e.g. a pillar type destination station by an electromagnet 6, Fig. 3, which reacts with an iron member 21 mounted on top of each vehicle, to lift the vehicle whilst moving from main track 1 and deposit it on rising track 2. The pillar type station, Fig. 4, includes a swinging section of track 3 which is moved by the arrival of a vehicle from a position in line with entry track 1 to a horizontal position in which it holds the vehicle and can then be swung to a position in line with the outlet track 2 whereat on receipt of a start signal it can be released to accelerate down to enter the main track at synchronous speed. Two main forms of control which can be combined are provided. The first, referred to as prearranged control, relies on the counting of intervals during each of which the vehicles travel a known number of wavelengths of the winding along the track. The distances between stations is adjusted whereby a vehicle can be released into a time lane which ensures its uninterrupted passage to its destination. In the second arrangement individual control of the vehicles is provided by the provision of replica vehicles which travel on replica tracks at the control station at speeds directly related to that of the vehicles they represent. Where the network includes tracks converging from despatch stations to a common main line the stations are arranged to be at different distances from a common point on the main line. This form of control is referred to as free passage control to differentiate it from directional control used where the tracks diverge from the main line to the destination stations. The replica track can be a fixed ring positioned adjacent a rotating ring carrying the replica vehicles or can be a magnetic tape or drum moving at a speed related to that of the vehicles on the track and carrying magnetic marks representing the vehicles.

A grooved track section for a toy railway has counting means to register the number of times a vehicle passes. The system Figs. 1 and 2 comprises a trip lever 25 having, projecting into the groove 11, a pin 23 and which is struck by a passing vehicle so that the nose 32 of the lever 25 strikes a pin 35 on a "units" disc 30 and moves the disc round on digit. The lever returns to the original position under the influence of a spring 27 whereupon a projection 38 on said lever 25 moves into the path of one of the pins 35 to prevent further rotation of disc 30 pending another operation of lever 25. A single tooth 42 on the "units" disc moves a "tens" disc 44 one digit at every complete rotation of disc 30. The discs may be returned to zero settings 'by clockwise rotation, as viewed in Fig. 1, of disc 34, a knob being provided on the upper side of the track for that purpose.
