Title: Improvements in siphonic means for discharging liquids from cisterns or like vessels
Inventor: SPEDDING BAYNE
IPC: E03D1/16
Filed: 1962-03-08
Abstract: 1,035,213. Siphon-discharge water-wastepreventers. CLAIMCOM PATENTS Ltd. June 4, 1963 [March 8, 1962], No. 8889/62. Heading E1C. Siphonic discharging apparatus has a hydrostatic valve 16, 17, 18 19 and 20 to prime a double siphon 12, 13, 14, 15 and includes a siphon 16, 17, which is primed when water in a cistern reaches a pre-determined level and then withdraws air from the top of the part 14, 15 of the siphon 12, 13, 14, 15, which is thus primed. Water is fed to the siphon 16, 17 through an aperture 27 open to the cistern and it discharges directly to the outlet 25, below the outlet leg 15. The passages may be open channels in one side of a block, to which a plate may be secured to complete their formation or in one side of each of two blocks securable together to form them. The channelled block(s) can be formed by a moulding process, e.g. by blow-moulding synthetic resinous material. The apparatus may be tubes connected by webs formed by blow moulding or otherwise. An auxiliary siphon 23, 24 removes most of the water left in the siphon 12 to 15 after the latter has been broken. The valve 16 to 20 is primed when the water in a cistern flows over a weir 33. Pre-formed inserts may be used to form some of the passages. In a modification the construction is simplified to give a more compact unit than that shown. There may be a constriction with a flared exit at or close to the outlet of the final leg of the double siphon to give a Venturi tube effect to speed up the priming thereof.

Title: Improvements in or relating to electric signal wave translating circuits
IPC: H03G11/00
Filed: 1946-03-22
Abstract: 609,788. Frequency and pulse modulation; valve circuits. STANDARD TELEPHONES & CABLES, Ltd. March 22, 1946, No. 8931. Convention date, April 2, 1945. [Classes 40 (v) and 40 (vi)] For selecting the portions of a signal wave between two amplitude levels, the wave is applied to deflect the beam in a cathode-ray tube backwards and forwards across a target electrode to produce pulses from the electrode from which the selected portions of the wave are derived, the input being applied through a variable gain amplifier and an adjustable deflection bias being provided. The invention is applied to removing interference from pulse signals, demodulating pulse modulated carrier signals and removing interference from a frequency modulated carrier. In one embodiment, D.C. pulses 20, 21, Fig. 2, from a variable gain amplifier 2, Fig. 1, are. applied to one of the vertical deflecting plates 13 of a cathode-ray tube 1, an adjustable bias source 3 being connected to the other plate 14. The output target electrode 17 is screened by a barrier electrode 15 with a narrow horizontal slot 16 across which the beam is deflected by the input pulses. By adjustment of units 2 and 3 the amplitude limits a, b of the input signal between which the beam strikes electrode 17 may be predetermined, so that interfering pulses 22, 23, 24 produce no output and desired pulses 20, 21 produce double pulses 26, 27, &c. in the output load resistance 7. A low-pass filter 8 converts these pulses to single rounded pulses 28 corresponding to pulses 20, 21. If the pulses have a sloping instead of a vertical leading edge they can be shifted in time position without varying their spacing by adjustment of the bias source 3. In a second embodiment, Figs. 3, 4, radio-frequency pulses 51 ... 56 and 57 are applied to the deflecting electrode 40 and deflect the beam above and below its rest position o at the centre of the barrier electrode 42. The latter has two slots 43, 44 which allow the beam to reach the output electrode 45 when the positive and negative half-waves, respectively, of the input pulses lie between the amplitude limits d, e and g, h, respectively. The resultant output, after integration in circuit 47, 49, is a series of demodulated D.C. pulses 67 free from interference by disturbing pulses 58, 59 and made up of unidirectional components 61 ... 66 corresponding to the half. waves 51 ... 56 of the radio-frequency pulses. In a third embodiment, Figs. 5, 6 (not shown), a frequency-modulated wave, subject to interference of the type producing amplitude modulation, is applied to the deflecting electrode of a tube with a barrier electrode having a single slot. The output target electrode is connected to a circuit tuned to the carrier frequency, in which appears a frequencymodulated wave similar to the input wave but free from interference.

IPC: H03K19/084
Filed: 1959-03-17
Abstract: 884,913. Transistor gating circuits. AVIATION, MINISTER OF. March 9, 1960 [March 17, 1959], No. 9172/59. Class 40(6). A transistor is made to operate as a diode by directly connecting its collector electrode to its base electrode. As described two such diodes Q1, Q2, each having their collector and base connected to the base of a third transistor Q3 form a gating or AND/OR circuit. Terminals El and E2 are normally at the same positive potential and a negative voltage is applied to the collectors of Ql, Q2 via resistor R1; an appropriate bias thus being applied to the base of Q3, so that the output terminal E3 is at substantially the same potential as the input E1, E2'. When a negative potential is applied to both the terminals El, E2, but not when only to one of them, the transistors Ql, Q2 cut off, the potential of the base of Q3 falls accordingly and also the output voltage from E3. Transistors connected according to the invention may also be used in high frequency circuits where very high efficiency rectifiers are required, or as catching diodes for defining voltage limits.

Title: Pressure fluid control means for use with track-laying vehicles
IPC: B62D11/08
Filed: 1954-04-01
Abstract: 754,472. Motor vehicle driving and steering gear. WESTINGHOUSE BREMSEN-GES. April 1, 1954 [April 2, 1953], No. 9574/54. Class 79 (2). In a track-laying vehicle having each track controlled by a fluid-operated clutch 12 and brake for steering purposes, pressure fluid passes to and from brake cylinders 14, 15, via control valves 18, 19, connected to a common pressure regulating valve 6, the control valve on one side of the vehicle being so shifted by clutch-actuating fluid that the brake on that side is disconnected from the regulating valve when the clutch on the other side is disengaged, and a clutch actuating valve 5 has two end positions I, V in each of which the clutches are disengaged and the brake applied. As shown, the clutches are spring engaged and the brakes pneumatically applied. The clutches may alternatively be pneumatically engaged and the brakes spring applied. The clutches are associated with pneumatic cylinders 10, 11 and the brake cylinders 14, 15 are connected to connections 4 of the valves 18, 19. An air supply pipe 7 is connected to the valve 5 which has five positions. In position III of the valve 5 the clutches are engaged and the brakes not applied. In position II or IV one of the clutches is disengaged for steering positions, the valve 5 being connected through a pipe 8 or 9, a rotary connection 17 between upper and lower frames of the vehicle, and a conduit 8a or 9a to the appropriate cylinder 10 or 11. The conduits 8a, 9a are each branched to a connection 3 of the associated valve 18 or 19 and to a connection 1 of the other valve 18 or 19. Thus, if the cylinder 11 is pressurized, a connection 2 in the valve 18 is disconnected from the connection 4 so that when the valve 6 is moved from position I to position II and the conduit 7 is connected to a pipe 16a air can only pass through the valve 19 to the associated brake cylinder 15, that is to apply the brake on the track whose drive is already disconnected. In a modification, the rotary connection 17 is replaced by the fluid lines on the upper frame energizing relay valves which connect the lines on the lower frame to an auxiliary supply tank thereon.
