Title: Improvements relating to Gating Devices.
Inventor: BOOHER ROBERT KENNETH
IPC: H03K19/096
Filed: 1968-02-20
Abstract: 1,159,773. Multi-phase logic circuits. NORTH AMERICAN ROCKWELL CORP. 20 Feb., 1968 [13 March, 1967], No. 8242/68. Heading H3T. A logic gate is set according to its input(s) during one phase of a clock cycle and during another phase, if it is in one of its states the output is clamped at the level corresponding to the state. Each of the logic stages shown utilizes a four-phase clock cycle (# 1 -# 4 ) with successive stages displaced by one phase. The sequence of operation of each stage is set out below stage 1 and the phases during which the sequence is followed is indicated in brackets beneath each stage, the true condition being a negative value - V and false zero. Thus, in stage 4, during phase # 2 , the lower phase-terminal of logic circuit 17 is at - V and the upper terminal is connected to - V through transistor 16. The self-capacitance of the stage, represented by 21, is thus charged. During # 3  transistors 18 and 22 also become conductive so that the output capacitance 20 and a storage capacitance 25 is charged. During # 4 , transistor 16 goes off and the lower terminal of the logic circuit 17 is returned to zero potential so that the capacitances 20, 21 and 25 can now be discharged or not according to the input logic. During # 3  and # 4  the output terminal 19 (and capacitance 20) are isolated from the circuit and the output signal is available for a further stage. If the previous stage output 1 is at its negative "true" value when the logic input to stage 4 is causing its capacitance to be discharged, a positive voltage is fed back and tends to reduce the time voltage or stage 3. Any reduction however causes transistor 9 to conduct because of the true value stored in capacitance 5 and this clamps the voltage at point 1.

Title: Improvements in or relating to method and apparatus for molding rods of nylon
Inventor: STOTT LOUIS LATHROP
IPC: B29B13/00
Filed: 1952-04-02
Abstract: 735,029. Moulding polyamides. POLYMER CORPORATION. April 2, 1952, No. 8381/52. Class 87 (2). Molten nylon is advanced by means of a screw feeder 9 through a nozzle I into a mould 12 which is preheated to a temperature above the melting point of the nylon. The perforate top closure 14 and imperforate bottom closure 13 are made of a metal, e.g. bronze, which has a higher coefficient of thermal expansion than the metal, e.g. steel, of the mould 12. By this means the closures are held securely in place when the mould assembly is hot. After the mould has been flushed out with an inert gas it is supported in a heating container 17 by means of screws 16 and heated to the correct temperature. The container is raised by means of a jack 19 until the aperture 15 in the top closure makes liquid-tight engagement with the nozzle 11. The filled mould is then provided with a further imperforate closure which overlies the closure 14. Finally the mould 12 is placed in a press the top plunger of which exerts high pressure against the two top plungers as the nylon cools. Specification 735,028 and U.S.A.

Title: Improvements in or relating to metal-clad electric switchgear of the draw-out type
IPC: H02B11/24
Filed: 1925-04-02
Abstract: 254,391. Reyrolle & Co., Ltd., A., Anderson, W., and Clothier, H. W. April 2, 1925. Switchgear structures.-In draw-out electrical switchgear having doors or covers for the sockets on the fixed member which are opened and closed by the movement of the draw-out member, the doors are operated through rods so arranged that the doors when fully opened free the operating rods from positive engagement with the draw-out portion. The arrangement of the gear is similar to that described in Specification 10536/08 and as applied to a three-phase duplicate bus-bar system comprises sockets A, A<1>, B on the fixed portion engaged by plugs C, C<1>, D on the draw-out member, the sockets being provided with pivoted doors or covers A<2>, A<3>, B. The pivots on which the doors rotate are carried by operating rods E, E<1> which move forward together, the rods being connected by members E<5>. The rods E, E<1> are supported at their inner ends in fixed guides F, their outer ends sliding in guide tubes G, G<1> carried on the movable portion. The lower rod E simultaneously operates the doors A<2>, B<1> which when the two switchgear members are moved into engagement fold into the space between the sockets A<1>, B. The upper door is moved into the space between sockets A, A<1> by the rod E<1>, the doors being returned into positions by springs when the switchgear members are separated. The lower door B<1> is connected by bevel gearing to the rod E so that in opening it rotates the rod hing- ing a pin E<4> carried thereon out of engagement with a lateral recess G<3> in the guide tube G, thus freeing the rod from engagement with the drawout portion, the pin E<4> merely sliding along the slot G<2> during further inward motion of the draw-out member. Springs R are provided to prevent sticking of the pins E<4> in the guidetubes. To completely detach the draw-out member the slide tubes G, G may be released by loosening the clamping screws O, O<1> with the draw-out member withdrawn. If however an attempt is made to remove the lower tube G. while the switchgear members are in engagement the tube G can only be removed after the locking pin P has been removed by means of a spanner. The two upper sets of doors for the bus-bar sockets are provided with slots M in their interconnecting webs co-operating with fixed curved catches N so formed that the doors cannot be opened by hand with the draw-out member withdrawn (see Fig. 4). If it is desired to earth the lower transformer socket, this can be opened by hand as shown in Fig. 6 and an earthed plug extension L can be moved inwards by the draw-out member. The preliminary opening of this door frees the rod E from engagement with the drawout member so that during its partial inward movement the doors covering sockets A, A' remain closed.
