Title: Graphic answer input device for teaching machine
Inventor: TARNOPOLSKY IGOR RAFAILOVICH
IPC: G09B7/02
Filed: 1969-11-03
Abstract: 1,269,689. Teaching machines; analoguedigital converters. FRUNZENSKY POLITEKHNICHESKY INSTITUT. 3 Nov., 1969, No. 53739/69. Headings G4H and G5G. An input device for a teaching machine is such that a pattern of discrete electric contacts is made in response to the tracing of a line. The device consists of a board 1 containing an array of conductive studs 2, a perforated insulating board 8 whose apertures overlie some of the studs 2, a sheet 10 of conducting material such as metal foil overlying the perforated board, and a blank 7 such as a sheet of paper overlying the conducting sheet. When a line is drawn on the blank, the sheet 10 makes successive contact through the apertures 9 with underlying studs. The studs have sockets in their lower ends and plugs 5 are employed to connect them to a logic unit of the associated teaching machine, the latter providing an indication of the correctness or otherwise of the line drawn. The device is stated to be applicable to the teaching of subjects in which graphs or other drawings are required of the student, e.g. geometry, mechanics, physics.

Title: Electrical generators
Inventor: ELLISON ARTHUR JAMES
IPC: H02K35/06
Filed: 1965-12-20
Abstract: 1,135,579. Reciprocating generators. NATIONAL RESEARCH DEVELOPMENT CORP. 9 Dec., 1966 [20 Dec., 1965], No. 53782/65. Heading H2A. An electrical generator comprises a member of magnetic material arranged for reciprocating motion, an electrical winding arranged to be energized by direct current to produce magnetic flux, the reluctance of the path for which varies with the position of the member, and means for allowing an alternating output current due to an alternating voltage generated in the winding when the above-mentioned reluctance changes, to be taken, without a substantial direct current component, from the generator. As shown, a cylindrical member 1 reciprocates between the positions shown inside a hollow cylindrical casing 2 around which two coils 3, 4 are provided. When coils 3 and 4 are energized by direct current, the path for flux produced by coil 3 includes the member 1 when it is in the extreme position shown, and the path for flux produced by coil 4 includes the member 1 when it is in the opposite extreme position. Thus the magnitudes of the fluxes alternately vary between maximum and minimum values as member 1 reciprocates. This flux variation induces A.C. in windings 3 and 4, and currents without substantial D.C. components can be extracted from the windings by means such as a transformer coupling. The member 1 may be driven by a single cylinder I.C. engine, or the arrangement 1, 2 may itself constitute the I.C. engine. The invention may take the form of a single cylinder, double piston, arrangement (Fig. 2, not shown). While the direct current may be provided from an external source, part of the A.C. output may be rectified and fed back for D.C. excitation. In the latter case, initial induction may be provided by a small bar magnet extending axially of the piston.

Title: Motor Vehicle Braking System.
Inventor: ELIAS ALBERT HARRY
IPC: B60T13/38
Filed: 1967-12-01
Abstract: 1,187,049. Fluid pressure brakes; hand and pedal actuation of brakes. FORD MOTOR CO. 1 Dec., 1967, No. 54830/67. Headings F2E and F2F. In a motor vehicle a wheel brake is connected by a mechanical linkage 1 to a control device 5 having a member 9 including a piston actuated by fluid pressure supplied from a power source to hold the linkage 1 in a position to hold the brake in the released position. A spring 19 acts on the linkage 1 to bias the linkage towards the brake applied position, while a control 17 actuable by the driver is operable to release the fluid pressure to permit the spring 19 to apply the brake. According to the invention a piston 33 is movable by the driver to apply a liquid pressure to the member 9 to move it to release the brake. The arrangement is intended to permit release of the brake even after failure of the fluid pressure supply. Member 9 comprises a first piston 11 in cylinder 13 operable by compressed air to release the brake via valve 17, coupled by a plunger 21 to a second piston 14 operating in a second cylinder 23. A restricted orifice 25 communicates the interior of plunger 21 with cylinder 15. A hollow rod 27 is fixed to the second piston 14 and communicates via flexible conduit 31 with the pressure side of piston 33 in master cylinder 35, operable by hand control 39 or foot control 37, which is provided with a ratchet 57. In position I of piston 33 its pressure side is connected via orifice 41 to reservoir 43 which is open to the atmosphere, but when piston 33 is moved into position II its pressure side is disconnected from reservoir 43. Reservoir 43 is also connected via orifices 41, 45 and conduit 46 with a port 47 in the wall of the second cylinder 15, so that in the position shown the pressure side of piston 33 and the second cylinder 23 are connected to reservoir 43 at atmospheric pressure. The space between the top of second piston 14 and the casing is connected by conduit 49 to conduit 46 so that the pressure therein is always the same as at port 47. Operation.-The brake is normally operated under air control, by means of valve 17. If, however, air pressure fails the brake is applied by spring 19, piston 11 falling at a rate determined by the forcing of liquid displaced from cylinder 15 by the second piston 14 through the restricted orifice 25 into chamber 23 and thence via conduit 31 into master cylinder reservoir 43. In such circumstances the brake can be released by operating rod 39 or pedal 37 to move piston 33 into position II. Initial movement of the piston disconnects conduit 31 from reservoir 43 and port 47, while further movement forces liquid under pressure into chamber 23 and via orifice 25 into the second cylinder, the pressure on the second piston 14 then raising linkage 1 to release the brakes.

When the vehicle passes over loop 13 a monostable 26 passes a positive pulse to AND gate 24 and a delay circuit 22. A second latch circuit 27 has the same truth table as latch circuit 18; the circuit arrangement is such that a vehicle without a transponder, or with a faulty transponder, causes a generator 28 to be triggered. Circuit 27 is reset by an input (B) effected by an operator after hearing a tone.
