Patent GB-2101426-A (GB)
Title: Emergency lighting
Inventor: KWAN LEUNG-CHUNG
IPC: H02J9/06
Filed: 1981-06-09
Abstract: In an emergency lighting device a relay 30 is normally energised by an AC mains supply to switch its contacts 30A, 30B, 30C, 30D to states opposite to those in Figure 2 so that a fluorescent light 10 is then energised from the mains and a battery 14 is trickle charged by a circuit (50, Figure 1, not shown). If the mains supply falls, a relay 54 is operated by the battery 14 to close contacts 54A so that the light 10 is energised from the battery via an inverter 58. If the lamp 10 fails or is not in place, charge build up at the output 58 of the inverter step-up transformer Tx is sensed by a transistor TR2 causing it to turn off so that relay 54 is de-energised and contacts 54A open to interrupt the supply of the inverter from the battery, thereby protecting the inverter from possible damage. A test switch (80, Figure 3. not shown) may be provided to simulate mains failure. <IMAGE>

Title: Double acting continuous flow system type pump
IPC: A61M5/142
Filed: 1980-11-18
Abstract: It is an object of the present invention to provide an improved fluid delivery system (10) for continuous and substantially constant delivery of liquids such as medications, nutrients, blood, plasma, etc. from a reservoir (14) to animals and human patients which employs a syringe type mechanism (11) with a reciprocating piston (26).

An additional object is to provide a sealing means which prevents contamination of the fluid and internal working elements of the pump during all stages of pump use and operation via exposure of the driving rod to external contaminants. A further object of the invention is to provide a fail-safe external valving system (101) that ensures that fluid is not supplied to the patient by gravity from the reservoir in the event of any failure of the pump.

Patent GB-813967-A (GB)
IPC: G01S7/292
Abstract: 813,967. Measuring duration of pulses. STANDARD TELEPHONES & CABLES Ltd. June 18, 1957, No. 19130/57. Class 37. [Also in Group XL (c)] An arrangement for measuring the duration of pulses comprises a cathode-ray tube having the pulses applied to one set of deflecting plates and a timebase source synchronized with the pulses and connected to the other set of plates, the waves generated by the timebase, or the signals by which they are synchronized being adjustably and periodically delayed by means including a periodically operating switch thus causing two images of the pulse to be simultaneously displayed on the screen, the adjustment of the delay effecting their separation then corresponding to the duration of the pulse at a required amplitude. In the embodiment of Fig. 1 pulses from source 1 are applied to the Y plates 3, 4 of the cathode-ray tube 5, a timebase 6 supplying sawtooth or other waves to the X plates 7, 8 which timebase is synchronized by signals supplied from source 1 of the same period as the test pulses. The synchronizing signals are supplied through an amplifier 10 to fixed and variable delay devices 11, 12 respectively, which are connected to a set of contacts 13 of a polarized relay 14 having its winding supplied with low-frequency A.C. so that signals from both delay devices will appear simultaneously on the tube screen, the fixed delay being To seconds (pulse 17), Fig. 2, and the variable delay being adjusted to T + T 0  seconds (pulse 18). In order to measure the duration of the test pulses at a predetermined amplitude level, e.g. 19, the delay device 12 is adjusted so that the point of intersection of the pulses lies on line 19, the difference T being then equal to the duration of the test pulses at levels 19, and device 12 may be calibrated to read this directly. Lines 19, 20, 21 could be marked on a transparent sheet or electronically on the tube. Device 11 may be replaced by a direct connection. In a modification (Fig. 3, not shown) the delay devices are placed after the timebase source. The embodiment of Fig. 4 is applied to the testing of television signals in which the synchronizing signals and test pulses are applied to a narrow bandpass filter 24 which selects the appropriate time wave component which is then fed through an adjustable phase shifter, to the movable spring of relay contacts 13, and then to fixed and variable phase shifters 26, 27 (corresponding to the time delay devices 11, 12) and then to an amplifier and limiter 28. The line synchronizing signals and the test pulses are applied to the Y plates 3, 4 and the phase shifter 25 is adjusted so that sweeps of the timebase coincide with the test pulses so that these and not the synchronizing signals are shown on the screen.
