IPC: G01R1/073
Filed: 1984-03-24
Abstract: Apparatus for testing a printed circuit board (10) comprises an insulating member (12) with conductors arranged, inter alia, at test point locations (A,B,C) together with a tester printed circuit board (14). The latter has contacts also located at test point locations (A,B,C). Each of these contacts is connected by a printed conductive track to a corresponding connection point at a periphery of the board. By means of edge connection this board may then be connected to automatic test equipment. By means of edge connection this board may then be connected to automatic test equipment. Both this test board, and boards to be tested, may be manufactured by computer aided design. The insulating member may comprise sprung pins set in an insulating plate. Alternatively it may comprise a rubber mat with localised conductive regions. An insulating mask sheet may be interposed between the insulating member (12) and the tester board (14) and this too may be manufactured by computer aided design.

Title: Electrosurgical system
Inventor: BLACKETT JOHN HAROLD
IPC: H02H11/00
Filed: 1984-09-12
Abstract: A method of and circuit for detecting unacceptable levels of current flow from the plate circuit of an electrosurgical unit to earth. A voltage wave form is applied to the plate circuit by means of the electrosurgical generator or a dedicated source (2). A voltage related to that existing between the plate circuit and earth is derived at the input to circuit means (ICI, D1, C3, IC2 and 3) and operated on to provide a signal indicative of the nature of the impedance between the plate circuit and earth. This signal is supplied to switching means (IC3, IC6) which generate a signal for actuating an alarm and/or shutdown of the generator should this signal indicate that the resistive component of said impedance is below a predetermined value. <IMAGE>

Title: Non-destructive ultrasonic testing of structures to measure stress
Inventor: VIRDI KULDEEP SINGH
IPC: G01N29/07
Filed: 1985-09-26
Abstract: The invention relates to non-destructive testing of a structure such as a bridge using an incident ultrasonic wave signal with pulses using a circuit 1 which allows measurements to be taken from two different kinds of transducers 2 and 3.

Abstract: A cable identification system or use in identifying a particular cable amongst a bundle of visually identical cables comprises a transmitter (7) to which one end of the cable is connected to receive a square wave signal from the transmitter, and a cable identification device (1) sensitive to the test signal. The cable identification device (1) emits an audio signal when a probe (2) associated with the device (1) is in the general vicinity of the radiating cable, the amplitude of which increases as the probe is moved nearer to the cable. A second, visual, signal provided by a dot bar indicator (5) operates when the probe (2) is relatively close to the cable and assumes a unique configuration (e.g. all dots lit) when the probe (2) is in immediate juxtaposition to the cable. Preferably, the system includes a hand set (9) which can be connected to the identified cable to establish a voice link between the user of the cable identification device and the position of the transmitter (7). <IMAGE>

Title: Arrangement for damping vibration
Inventor: SMALL DAVID JOHN
IPC: F16F7/108
Filed: 1988-06-17
Abstract: For damping vibration in, for example, propeller blades or turbine fins, a slug of metal (1) is embraced by two viscoelastic O-rings (5) and forced into a cylindrical cavity (7) formed, e.g. by drilling in a blade (15), the slug being supported by the compression of the O-rings. The compression of the O-rings (5) is chosen, in conjunction with the mass of the slug (1), for resonance in a translational mode at the frequency at which vibrations need to be damped. Resonance at the same frequency in a torsional mode can be achieved by spacing the O-rings apart symmetrically a distance equal to 1/#3 the length of the slug.

Title: Liquid storage and transfer systems
Inventor: SAVAGE BASIL
IPC: B67D1/08
Filed: 1988-06-18
Abstract: A number of beer kegs 2 are stored in a cellar 1 which is cooled by a refrigeration unit 5 which supplies a first heat- exchanger 7 in the cellar 1. A beer pump 3 pumps beer out of each keg 2 and out of the cellar 1 to a point of dispense, via a pipe 4. Outside the cellar 1, the pipe 4 is cooled by a coolant fluid (e.g. water) which is pumped through flow and return pipes 13, 14 by a pump 12. The coolant fluid is in turn cooled by a second heat exchanger 20, which heat exchanges with the ambient air in the cellar 1 or with the first heat exchanger 7. Thus the substantial heat reservoir which is already provided in the cellar 1 by the refrigeration unit 5 and first heat exchanger 7 is utilised to afford relatively simple cooling of the beer as it travels through the pipe 4 outside the cellar 1. The invention may be extended to the cooling and heating of other liquids. <IMAGE>
