Title: Analysis of biological material by a non-linear dielectric spectrum
Inventor: KELL DOUGLAS BRUCE
IPC: G01N33/487
Filed: 1991-06-03
Abstract: Biological cell material, substrates therefor, or inhibitors of cell metabolism are determined by applying an AC electrical potential across a sample of the biological material so as to produce a non-linear dielectric spectrum, and obtaining a detectable signal from said spectrum. The potential is typically of a first frequency and the measured response is at a second frequency substantially not overlapping with the first frequency. Alternatively, the applied potential may be sinusoidal and the entire frequency of the spectrum may be observed to ascertain the presence of harmonics. As shown, a sample in test cell O is compared with a reference of the same conductivity in cell 1. AC 13 is applied to both cells and the output of both cells is analysed by microcomputer 14. <IMAGE>

Abstract: A gas burner assembly (5) especially for use in a gas-fired thermal storage type of waterheater comprises a cylindrical ribbon type of burner (14) mounted in a casing (13) to which premixed natural gas/air is fed under pressure by a fan (10). A conduit (12) that connects the fan (10) with the casing (13) includes a pair of flat plates (23A, 23B) arranged in cruciform fashion and these serve to reduce the turbulence of combustion air fed into the conduit (12) by the fan (10), the air entraining natural gas injected into the conduit (12) by an injector (24) located in the conduit (12) adjacent to the burner (14) and having a scarfed outlet end (25). The casing (13) houses a diffuser (27) in the form of a hollow cylinder (28) that is open at its rear end and closed at its front end, adjacent to the burner (14), by an apertured plate (29). The plates (23A, 23B), scarfed injector (24) and diffuser (27) all serve to improve mixing of the combustion air with the gas and the performance of the burner.   <IMAGE>

Title: Detecting faults on a flat, reflective, moving surface
Inventor: IKIN JOHN BRUCE
IPC: G01N21/89
Filed: 1993-03-26
Abstract: The apparatus comprises a light source 6, for producing a beam, which is caused to scan across the flat surface (1), an optical system which causes the scanning beam after reflection from the flat surface (1) to converge at a focal point on a photodetector (14) to which is coupled a logarithmically sensitive amplifier, the photodetector having a sufficiently large working area to accommodate the desired range of surface deflection light signals, there being present in front of the working area of the photodetector a neutral density wedge (15) so located and being of such a size that all the reflected light passes through a part of the wedge, together with means to record graphically the detected signals. The focussed spot is deflected across the wedge by any perturbation, e.g. coating faults, by an amount proportional to the gradient of the surface at the fault. The density of the wedge is graduated in such a way as to produce a photoelectric signal proportional to the antilog of the gradient, which is converted by the log amplifier to a signal proportional to the gradient profile. <IMAGE>

Title: Atmospheric gas burner
Inventor: POOLE JOHN
IPC: F23D14/04
Filed: 1993-12-06
Abstract: An atmospheric gas burner comprises a central deflector element 14, at least two inwardly pointing gas jets 12 and a gas supply chamber 4 extending around the deflector element to supply gas to the gas jets.

Patent GB-2277629-A (GB)
Title: Envelope waveform producing circuit
Inventor: IMAMURA MIYUKI
IPC: G10H1/057
Filed: 1994-04-15
Abstract: A ROM 1 contains a group of parameters relating to the attack and sustain amplitudes (AL, SL) and to the rate of increase of amplitude to the attack level (AR), rate of decrease to sustain level (DR) and rate of decrease at release (RR). More than one group may be stored. On receipt of a key-on signal an up/down counter 5 is controlled by a clock pulse from a frequency divider 4b to count at a rate sequentially determined by the rate signals AR and DR to values determined by the corresponding level signals AL and SL. On receipt of a key-off signal the clock pulse controls the counter 5 to count down to zero at the rate RR. A data conversion ROM 6 is provided to convert the rise and fall of amplitudes from linear to exponential form. In a second embodiment (Figures 7, 8) the output of up/down counter 5 is D to A converted and an envelope waveform obtained using a transistor Tr1. The exponential conversion occurs in an antilog amplifier. In a third embodiment (Figures 9, 10) each of the attack, decay and release portions is further divided into a plurality of sections, so obviating the requirement for exponential conversion means. <IMAGE>

Title: Line to ground fault detection for control system of electromagnetic clutch for a vehicle
Inventor: ARIKATA HIROTO
IPC: H02H3/027
Filed: 1994-08-10
Abstract: A control system of electromagnetic clutch for vehicle, capable of preventing an erroneous line-to-ground fault detection due to a noise or the like. The system includes: a clutch current control means 1; a clutch current operation means 2A; an electromagnetic clutch 5; and a clutch output terminal voltage detection means 6. When a line-to-ground fault exists in the electromagnetic clutch 5, the voltage level of a clutch output terminal 29 during a reverse excitation is driven to its low level. Such ground fault state is detected at the clutch output terminal voltage detection means 6 and the result of detection is supplied to the clutch current operation means 2A. If the ground fault state in the reverse excitation mode continues for a certain time period, the clutch current operation means determines it as a line-to-ground fault, where a clutch current command signal SI and a clutch release signal SO to be supplied to the clutch current control means 1 are set into the direction of releasing the electromagnetic clutch 5. <IMAGE>

Title: A press fit of a splined hub on a splined shaft
Inventor: DIGEL WOLFGANG
IPC: B60K17/24
Filed: 1994-10-03
Abstract: In a press fit arrangement between a spline shaft 1 and a spline hub 2, the spline shaft has, on one end region, a spline-shaft toothing 4 and the spline hub has an inner spline-hub toothing which corresponds essentially to the spline-shaft toothing. In the prefabricated state, the spline-hub toothing is provided with an undersize in relation to the spline-shaft toothing. Those edges of the tooth flanks of the spline-shaft toothing at the front on the insertion side are designed as cutting edges 5 which, during the insertion of the spline shaft 1 into the spline hub 2 come into engagement with a chipping effect on the tooth flanks 9 of the spline-hub toothing. So as to avoid a risk emanating from these chips, the depth of insertion of the spline shaft into the spline hub is limited by a shoulder 3, and the distance A between the cutting edge 5 and the shoulder 3 is smaller than the extension B of the spline hub. As a result, the chips remain within the spline-hub toothing of the spline hub. <IMAGE>

Title: Electrostatic discharge protection circuits using biased and terminated PNP transistor chains
Inventor: MALONEY TIMOTHY J
IPC: H02H9/00
Filed: 1995-01-09
Abstract: In an integrated circuit requiring ESD protection, a bias network is used to augment diode strings 26, 27 to distribute small but significant forward current to the diodes. Also employed is the use of cantilever diodes which provide PNP Darlington gain block for ESD protection rather than for amplifying signals in bipolar ICs. The termination supplies final base current to the gain block for a limited amount of time, so that ESD charge can be shunted harmlessly through the PNP chain, but ensures that the structure draws no current from a stable power supply, long term. The entire structure is able to absorb noise spikes as well as ESD pulses. The termination also makes provisions for discharging its capacitor between ESD pulses, as is necessary for standardized testing. The invention has value as an IC power supply clamp, and reduces the damage often seen on IC power supplies during extensive ESD testing. <IMAGE>
