R., 29, Abbey Road, St. John's Wood, London. April 12, 1932, No. 10524. [Class 38 (iv).] In apparatus for producing variations in a neor or like sign E by means of an oscillatory circuit associated with a thermionic valve V, the variations are produced by varying the voltage applied to the valve anode or by varying the flow of electrons to the anode. As shown, the valve filament current is varied by means of a resistance R<1> or potentiometer P<1> which may be varied automatically by means of a motor or clockwork- The resistance &c. may be in the circuit of a transformer primary, the secondary of which energizes the filament. In another arrangement, the filament has a temperature lag, and a switch, operated'mechanically, electrically or thermally, for example by a bimetallic strip, is connected in the filament circuit. In other arrangements, (a) the variable resistance or potentiometer is connected between the high tension supply and a point t in the primary P, (b) the grid leak is variable, or (c) the variable resistance &c. is in the circuit of a primary having one secondary connected between the point t and the filament, and another secondary supplying the filament. Several lamps, each with a separate valve generator, may have their control units operated by single motor, so that they will light up gradually in turn.

Abstract: 802,592. Delivering measured quantities. GASKELL & CHAMBERS, Ltd. April 3, 1957 [April 12, 1956], No. 11124/56. Class 106(5) Apparatus for dispensing measured quantities of beverage comprises a cylinder 4, a piston 3, a spring 16 acting to impart relative movement to the cylinder and piston in a direction to cause the latter to occupy the inner end of the cylinder, valvecontrolled inlet and outlet openings 6, 7, means for supplying pressurized beverage to the inlet 6, and mechanism operated by the relative movement of the piston and cylinder for ensuring that when the inlet valve is open the outlet valve is closed and vice-versa. As shown, the cylinder 4 is slidably mounted on the stationary piston 3 which is provided with inlet and outlet passages 9, 10 leading from the inlet 6 and outlet 7 to the inner end of the cylinder. Each of the passages 9, 10 has a valve 11 connected through an adjustable stem 13 to a bell-crank 14, which is pivotally mounted on the piston and actuated by a pivoted over-centre spring plunger 21 arranged to be actuated in turn by a lever 18 provided with two rollers 19 co-acting with inclined slots 20 in the cylinder. When pressurized beverage is pumped through the inlet 6 (the outlet 7 being closed), the pressure forces up the cylinder, against the action of the spring 16, until it is arrested by an abutment, and at this stage the slots 20 act through the lever 18 and plunger 21 to reverse the position of the valves so that the beverage flows from the outlet port 7 under the action of the spring. An indicator may be provided so that an operator can maintain the upper part of the cylinder partially filled with beverage. When a greater rate of dispensing is required, two units may be mounted side-by-side so that one is charged while the other is discharged, or, when a power-operated pump is used, both inlets can be connected to the pump and a common 3-way valve-controlled outlet provided.

Title: Improvements in or relating to short wave oscillation apparatus
IPC: H03B5/18
Filed: 1937-04-19
Abstract: 478,474. Valve circuits ; electric resonators. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 19, 1937, No. 11150. Convention date, April 22, 1936. [Classes 40 (iii) and 40 (v)] In order that the frequency of a set of short-wave oscillators working in parallel may not be disturbed when the number of oscillators is changed, either their input or their output circuits are connected to the same line resonator or other tuned circuit, which acts as a tank circuit. Several resonators, each associated with a group of oscillators, may be similarly connected to a central oscillator. In the arrangement shown in Figs. 1, 1a, the grid of each oscillator valve 3 is connected to the corresponding plate through a U-shaped conductor 7 and a point on this is connected through a conductor 9 to the inner conductor 1 of a line resonator 1, 2, at a point on the conductor so chosen as to secure matching of the impedance. The inner and outer conductors 1, 2 are conductively connected at their lower ends, while their upper ends form a condenser to the plates of which the output leads l, l are attached. The spacing between the plates can be adjusted by means of a screw 11. The oscillators 3 surround the resonator 1, 2, and both they and it are mounted on an earthing-plate. In a modification, Fig. 2 (not shown), each oscillator is coupled to the resonator by means of a resonant circuit comprising a wire rectangle with a condenser in one side ; the vertical end of the rectangle lies near and parallel to the inner conductor 1, at a position whose distance from the end of the resonator determines the strength of the coupling. A threaded ring 18, Fig. 3, is connected to the earthing-plate and enables the distance of the earth point from the end of the resonator to be adjusted. A rod 19 inside the inner conductor 1 enables the capacity between the conductors to be adjusted. This capacity is increased and radiation is prevented by a cap 21. Several sets of oscillators may be operated in parallel by connecting their common resonators to a central resonator, Fig. 4 (not shown). Several tiers of such subordinate resonators may be mounted one above another, and their couplings 14, Fig. 6, may be located at points where the standing wave exhibits corresponding phases. The resonator may be shortened if capacity is inserted in the inner conductor 1 as at 22, 23. Instead of a resonator 1, 2 a pair of plates or rings 26, 27 forming a condenser may serve to couple to oscillators 3 to a load circuit 28. In further modifications, (i) the oscillators may be of the push-pull type; (ii) the grids of the oscillators may be connected to one line resonator while their plates are connected to another; (iii) the invention may be applied to amplifiers as distinct from oscillation-generators ; and (iv) the outer cylinder may be replaced by three or more rods, which may be straight or curved, and may afford a magnetic coupling with the conductor 7, Fig. 1, in place of the capacitive coupling 9.
