Abstract: 1,063,960. Valves. FARM AUTOMATION Ltd. Aug. 25, 1965 [Sept. 24, 1964], No. 39050/64. Heading F2V. A valve, e.g. for supplying livestock with liquid, is operated by relative tilting or axial displacement between valve stem 3 and body member 1 to unseat closure 4 and is provided with means to restrict the relative tilting to prevent opening in at least one direction so that e.g. the device may be used with the stem in a non-vertical position. The valve may also be opened by relative axial displacement against the spring 8 and, in one embodiment, is provided with a hollow drinking cup 5 through an opening 6 whereof the liquid is supplied to the animal's mouth. In an alternative embodiment (Figs. 4 and 5, not shown), the cup (5) is omitted and the valve is actuated directly from an axially projecting portion (3b) of the stem (3). The through bore in the body member 1 opens out from a relatively small cross-section at the end 2b, which may be longitudinally grooved to provide additional flow, to a larger cross-section 2c to accommodate the tilting. The tilting may be restricted in one direction by a stop comprising a transverse screw intersecting the bore, a segment-shaped plug inserted in the bore or a flat (10) (Fig. 2, not shown) formed on one side of the bore or the tilting may be restricted to one direction only by forming the bore as an elongated slot of the width of the stem (3) (Fig. 2a, not shown). The bore (2d) adjacent the valve seat (Figs. 4 and 5, not shown) may also be eccentric to the larger bore (3b) to provide the restriction to tilting. The stem (3) may additionally be provided with a tapered portion (11) in the region 2b of the bore adjacent the seat (Fig. 3, not shown) so that the through flow may be varied upon axial displacement of the stem. In a float operated tank supply valve (Fig. 6, not shown), a lip (15) of the float (13) shrouds the end of the body member (11) and tilting is restricted upwardly by any of the previously mentioned means, so that the valve remains closed when the tank is full, and the bore (2<SP>1</SP>) may be tapered. The float valve construction provides a " snap " closing action.

Title: Improvements in or relating to electronic switching circuits
Inventor: LEWIS ALAN
IPC: H03K17/68
Filed: 1964-09-25
Abstract: 1,121,613. Switching circuits; noise generators. EVERSHED & VIGNOLES Ltd. 3 Sept., 1965 [25 Sept., 1964], No. 39227/64. Headings H3B and H3T. A switching circuit for selectively connecting one of two inputs to an output in response to a switching signal comprises transistors or valves VT2, VT6 rendered conductive respectively by the two polarities of an input signal at E, and emitter-coupled switching transistors VT3, VT4 (or cathode-coupled valves) rendered conductive respectively by the outputs of VT2 and VT6. With one polarity of the E signal, VT2 and VT3 conduct allowing an A.C. input at A to pass to the output terminal O/P; with the other polarity of the E signal, VT6 and VT5 conduct allowing an A.C. input at B to pass to the output. With a cyclic signal at E the output will then contain the waveforms of A and B alternately (as at F), which may be of different amplitudes and/or frequencies. Alternatively, the input of emitter-follower VT1 or VT5 may be earthed for A.C. when only a single input is required to be passed or blocked. The circuit may pass only small fractions of a cycle of the A.C. input. Several of these circuits may be connected in series to route selected A.C. inputs to a common output, e.g. in automatic testing. Alternatively, several of the circuits may be joined in parallel, each being connected in series with a resistor of different magnitude to provide a variable attenuator for wide-band noise. Separate inputs are provided at A and B for high- and low-frequency signals, and multiple inputs are provided at E for a plurality of control signals. A diode D13 ensures that the conduction state of VT6 is always opposite to that of VT2. A potentiometer RV1 is set to balance the circuit so that no D.C. appears in the output.
