Abstract: 915,937. Drainage valves; drainage systems. LILJENDAHL S. A., J. May 25, 1959 [May 28, 1958], No. 17773/59. Class 33. In a sewerage system comprising one or more closet bowls, urinals or like sanitary conveniences connected through individual discharge valves to an outlet conduit SE terminating in a sewage collecting receptacle LBE in which a vacuum is maintained, for transporting sewage thereto by suction on opening any discharge valve whence it is transported by conduits E to a main receptacle B, and means to create an air pressure difference between receptacles LBE and B, cut-off means e.g. a plunger 3, is provided in the outlet conduit SE actuated for closure by a control device to interrupt communication between the conduit SE and the receptacle LBE upon a continuous flow of air into the conduit SE for a time considerably in excess of the time during which a particular discharge valve is normally open and to maintain the plunger 3 closed until the air flow has ceased. The control device comprises a cylinder 6 and a piston 7, connected to the plunger 3, and movable therein against the action of a restoring force, the space behind the piston 7 being connected through a passage 9 to the conduit SE, the air entering the latter thus moving the piston 7. The piston 7 is coupled with the plunger 3 through a connection between a pin 12 and a slot 11 in a piston rod 10 rapidly to move the plunger 3 to its closed position when the piston 7 has moved downward a predetermined distance. The conduit SE then communicates with the receptacle LBE through a narrow flow passage 17. At least two conduits SE extend into the receptacle LBE, each closed at the mouth by a valve disc 4 with a counterweight 5. The receptacle LBE may be discharged by compressed air, when communication between it and the vacuum source is interrupted by a valve device. Specification 867,664 is referred to.

Abstract: 691,839. Television. EDISON SWAN ELECTRIC CO., Ltd. Aug. 2, 1951 [Aug. 11, 1950], No. 18334/51. Class 40 (iii). Relates to means for rendering an amplituderesponsive television sync. separator relatively unresponsive to high-amplitude interfering pulses in a negatively-modulated television system. As shown, the positively poled composite video signal 17 is applied to the grid of a triode separator 10 through a coupling network comprising a shunt resistor R1, a pair of coupling capacitors C1 and C2 in series and a discharge resistor R2 in parallel with capacitor C2, the circuit functioning as a grid-leak detector to develop a bias which cuts off the valve except during sync. pulses. For equal transmission of the line and field sync. pulses and for maximum reduction of interference by random noise pulses, the following conditions should obtain: (a) the capacity of C1 should be ten to a hundred times that of C2; (b) the time constant R1, C1 should be somewhat greater than the field period; (c) the time constant R2, C2 should be not greater than a few line periods; and (d) the ratio of R1 to R2 should be approximately equal to the ratio of the capacitative impedance of C2 to the dynamic input impedance of valve 10; if a high-gain valve is employed, the dynamic input impedance is normally capacitative as indicated by C3 but if not, external capacity may be added. Suitable component values are given for a 525 line, 60 field system. In a modification, Fig. 2 (not shown), the large coupling capacitor is in series with discharge resistor R2 across the small coupling capacitor C2.

Abstract: 563,020. Converting rotary into oscillating motion. BRITISH THOMSONHOUSTON CO., Ltd. Dec. 28, 1942, No. 18390. Convention date, Dec. 31, 1941. [Class 80 (i)] Consists in a variable stroke oscillating mechanism particularly for actuating the agitator of washing machines. The driving shaft 6 is actuated by an electric motor 17 through a worm 14 and wheel 13 which is connected by a rod 18 to a friction gear segment 29 pivotally supported at 32 on a link 31. One end of this link is pivoted to an arm 34 hinged to the gear casing 4, and the other end is urged against a stop 36 by a spring 37 which tends to press the link against a cam 43 adjustable by a lever 46 adapted to engage notches 48 in a slot 47 in a supporting skirt 2. The friction surface on the segment 29 comprises an arc having its centre at a point 50 and, therefore, the central part of such surface will project beyond an arc passing through its ends and concentric with the axis of oscillation of the segment. By moving the lever 46 the amplitude of oscillation of the shaft 8 may be varied from zero up to a maximum value. Excessive pressure between segment and pinion is prevented by the yielding of the spring 37.

Abstract: 1,101,488. Transistor amplifying circuits. PHILCO-FORD CORPORATION. 3 May, 1965 [4 May, 1964]. No. 18489/65. Heading H3T. In a transistor amplifier, having a diode 15, connected in parallel with a resistor 13 in the emitter circuit of the amplifying transistor 10 a gain control voltage is applied to the base of this transistor so as to cause the impedance of the emitter circuit to vary with the control voltage amplitude and adjust the negative feedback applied by the diode 15 and resistor 12. The circuit may be the signal frequency amplifier of a superheat transistor radio, in which case the input at 11 is a modulated carrier wave and the gain control voltage in an A.G.C. voltage. The diode 15 is forward biased for normal signals by potential divider 17, 18. The circuit is arranged so that an excessive amplitude signal causes the A.G.C. voltage to turn off diode 15 leaving resistor 13 providing the maximum negative feedback. The A.G.C. voltage may be obtained from the emitter of a subsequent i.f. amplifier stage. Output from the amplifier is taken from the tuned circuit 20, 21.
