Title: Improvements in toy or model vehicles
Inventor: FAIRBAIRN HOWARD WILLIAM
IPC: A63H17/26
Filed: 1966-07-01
Abstract: 1,136,785. Improved couplings for toy vehicles. METTOY CO. Ltd. 30 June, 1967 [1 July, 1966], No. 29695/66. Heading A6S. A toy tractor and trailer combination adapted to be detachably coupled together comprise a trailer vehicle, of which 6 is a portion, which bears a downwardly projecting stud 7 and has an enlarged head 8 at the lower end of its shank and a tractor vehicle including a chassis 9, supported on wheels 10 and carrying a body 11 with a downwardly and rearwardly sloping ramp 13. On the upper surface 12 of the tractor-vehicle is formed an aperture 14 in which the stud can engage, the aperture 14 comprising a part large enough to admit the head of the stud and a second part extending from the first part (in the direction of the first-mentioned vehicle) wide enough to admit the shank of the stud but narrower than the head. During coupling, the tractor moves backwards and the head 8 engages the ramp and rides up onto the surface 12 while guided by an upstanding U-shaped guide rib IS until it seats into the aperture 14. Then a forward movement of the tractor enables the head 8 to engage between a downwardly projecting retaining ring 16 and a spring 17, the latter thrusting the stud upwards to engage the head within the ring 16.

Title: Logic circuit
IPC: H03K19/086
Filed: 1967-06-28
Abstract: 1,183,537. Logic circuits. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 28 June, 1967 [30 July, 1966], No. 29855/67. Heading H3T. In a current-steered logic circuit with emittercoupled transistors having A and B signals applied to the respective bases, the B signal is applied in series with a D.C. source of value lower than the swing of the B signal, so that the circuit realises a BUT NOT function, the collector voltages representing A.#B and #A.B. The voltage source may be included between the B input terminal and the base, between the B terminal and ground, between the emitter and the common-emitter constant-current source, or in series with the collector load of the preceding stage. The source may be in the form of a series resistor and a shunt constant-current source. Fig. 8a shows such an arrangement having a series resistor R2 and a constant current source Q2 comprising a transistor and two resistors. A similar circuit is used for the source of the constant common-emitter current I. The A and B inputs comprise emitter-coupled transistors acting as OR gates and for level-setting, so that the output C represents (A1+A2) + #(B1 + B2) and #C represents #(A1+A2).(B1+B2). Further A and B inputs may be provided. The voltage across R2 is preferably half the swing of the B signal. Temperature compensation is achieved if the coefficients of the transistors and of the resistors are matched. If the output C is connected to one of the B inputs, an RS bi-stable circuit is obtained with the A inputs for set and the other B input for reset. The circuit may be constructed in monolithic integrated form.

Title: Improvements in and relating to electric switch gear
IPC: H02B11/04
Filed: 1922-11-01
Abstract: 209,527. Trencham, H., British Thomson-Houston Co., Ltd., and Heath, H. C. Nov. 1, 1922. Switchboards of the truck or draw-out type have a movable shutter for covering the fixed contacts mounted on the stationary frame and linked to one arm of a bell-crank lever, the other arm being engaged by a portion of the sliding carriage to raise or lower the shutter. The movement of the sliding frame 24 is effected by rotation of the worm 26, Fig. 2, which drives the worm wheel 27 on the shaft 28, on which is a crank 29 linked to a rod 31 carrying a stud 32. On the same shaft 28, a cam 38, Fig. 3, with a pair of notches 39 is mounted and the notches may be engaged by a roller-tappet 41 mounted in a frame 42 which is guided by a pin 45 passing through a fixed member 24 and is pressed by the spring 44 into engagement with the cam. The free end of the pin 45 presses upon the tripping bridge 47 of the circuit-breaker at all positions of the carn except those in which the. roller engages the notches. These positions correspond to the ' in ' and ' out ' dispositions of the truck-operating mechanism. In the position shown in Fig. 2, the gear mechanism has been employed to withdraw the truck to the ' out ' position and, thereafter, the truck has been moved by hand to the ' fully out ' position. The truck can be pushed into the ' out ' position only when the operating linkage. 29, 31 is in the ' out ' position shown, in which the stud 32 does not foul the end of the fixed abutment 33 but rides into engagement with the slot 34. The final traverse of the truck is effected by rotating the worm-wheel 27 in the anticlockwise direction, the link 31 pulling on the slotted abutment. If the circuit-breaker is closed, the first part of the final movement opens it bv the rotation of the cam 38. In the final traversing movement, an inclined guideway 23 engages a pin on a bell-crank lever 18 pivoted at 19 and connected at 17 to a link 16 jointed to the arcuate shutters 13. Consequently, the shutters are raised from the position in which they cover the opening to the fixed contacts. In withdrawing the truck, the first part of the movement trips the circuit-breaker, if closed, through the medium of the cam 38, and, subsequently, the guideway engages the pin 22 and draws down the shutters to cover the live contacts.
