Filed: 1973-08-23
Abstract: 1384830 Shift registers HITACHI Ltd 23 Aug 1973 [25 Aug 1972] 40047/73 Heading G4C [Also in Division H3] A 4-phase dynamic shift register comprises two C-MOS logic circuits (see also Division H3) connected in cascade. In operation, when clock pulse # 1  reaches the "O" level, T 23  is turned off and T 21  conducts to charge an output capacitance C L  and the parasitic capacitances associated with logic circuit LB 3  via T 22 . Subsequently when # 1  returns to the "1" level, T 23  is rendered conductive and the charge or discharge of C L  is determined by the level of the input signal Vin to the logic transistor T 24  during the remainder of the period of conduction of T 22 . The second circuit functions in a similar manner during the # 3  # 3+4  periods. The FETs T 22 , T 32  may each be replaced by a pair of parallel connected FETs driven by separate clock pulse trains # 1 , # 2 ; # 3 , # 4 .

Abstract: 1,117,942. Injection moulding sealing rings. HEPWORTH IRON CO. Ltd. 3 Jan., 1966 [3 Oct., 1964], No. 40369/64. Heading B5A. A moulding comprising a succession of synthetic rubber 0-rings spaced apart by integral thin connecting portions is made by injection moulding, the moulding is removed from the mould and the connecting portions are severed to separate the rings. The method comprises the steps of bringing together two longitudinally parting mould halves 1 urged to the open position by springs 21 and carried on one platen of an injection machine by a mounting plate (4) having a central bore (6) which locates a spigot (7) of a core 8, while mounted on the other platen (not shown) is a mounting plate 14 seating a core 11 having a spigot (12) and central bore 25. As the platens move together dowels 18 enter holes (17) in the plate (4) before diverging dowels 19 enter corresponding holes 20 in the mould halves 1 to close these about the cores 8, 11. A central nozzle-receiving sprue (24) in a locking plate 16 connects with the bore 25 which leads by central, radial passages 26 in the end of core(s) 11 to four gates (27) circumferentially spaced round an 0-ring forming cavity 28 which is connected at each side to a similar cavity 28A by four gates 29 radially offset with respect to the gates (27). Likewise cavities 28B, 28C are connected by gates 29A, 29B each radially offset with respect to the preceding one(s) so that all the rubber to a given cavity unites prior to passing to the next. The last cavities 28C in each core are connected by gates 29C to overflow cavities 30. After injection, the rubber is cured by heaters in the mould or cores, the mould is then opened, the moulding staying on the core 11 from which it is subsequently manually stripped. Each 0-ring 33 is separated by cutting knives or wires. In a modification (Fig. 6, not shown) the 0-rings are connected by relatively thin tubular portions (36) which may be severed by smashing after freezing with solid carbon dioxide. The cores may be collapsible or expansible, while the rubber is butyl or like synthetic rubber.

Class 40(7) [Also in Group XL(b) ] A waveguide switch for connecting four waveguide channels a, b, c, d in pairs in two different ways comprises two waveguides 3, 4 with directional couplers 1, 2, preferably 3dB, spaced apart and a metallic tape 7, perforated or slotted at 8 and 9, Fig. 3, for introducing reflectors simultaneously into the waveguides 3 and 4 between the couplers. The distance between the nearest points of the perforations or slits 8, 9 is equal to the distance l between the guides 3, 4. In the construction shown in Fig. 4 an endless metallic tape 10, slotted at 13, 14, 15, 16 is introduced into the guides 3, 4 by being wound on two similar pulleys 11, 12. The distance between the nearest points of the slits 13, 14 and also that between the slits 15, 16 are equal to the distance l between the guides 3, 4. The positions of the slits in the tape 10 are so determined that they can be simultaneously positioned within the guides 3, 4. The horizontal distance between the portions of the tape and the diameters of the pulleys are equal to a quarter of the wavelength propagated in the guides 3, 4. The openings of the guides 3, 4 through which the tape 10 penetrates and emerges are provided with traps 17, 18, 19 and 20. Two parallel tapes moving in opposite directions can be used. The switch described above can be used to connect a transmitter and two antennae alternately or to connect the transmitter and the antenna of a system of radio-detection so that the presence of the latter is not disclosed during operations of regulation or testing. In the latter case the channel c of the switch is connected to the transmitter, channel b to the antenna, and the channels a and d to non-reflecting terminal devices which are placed in the channel a for dissipating the power of the waves produced by the transmitter.
