Title: Pulse signal analysis
Inventor: GENT CHRISTOPHER ROBERT
IPC: G01S7/02
Filed: 1981-04-23
Abstract: A method of analysing a set of pulses to identify within that set a series of pulses having approximately constant repetition frequency comprises the steps of;     (a). storing all pulses occurring within a sampling window, (b). forming a histogram of the time intervals occurring between all pairs of pulses (i.e. between each pulse and every other pulse), (c). determining from the histogram intervals occurring at a statistically significant non-random rate, (d). identifying within the latter intervals any group of intervals forming an arithmetic progression, such a group corresponding to one series of pulses of constant repetition frequency in the sampling window, (e). eliminating the identified series of pulses from the sampling window using a gating technique set to look for the pre-determined interpulse time intervals specified in step (d) and, (f). repeating steps (b) to (e) until all the pulses remaining in the window are random.   <IMAGE>

Title: Conductive element, method of preparing the conductive element and photovoltaic cell comprising the conductive element
IPC: C01G19/02
Filed: 1981-07-23
Abstract: A conductive element comprises a sodalime glass support having a coating of polycrystalline stannic oxide (SnO2) and a fluorine dopant and has a transmittance greater than 70% to radiation of a wavelength between 400 and 800 nm and an electrical resistance of less than 30 ohm/square. It is useful in thin film cadmium sulphide/cadmium telluride photovoltaic cells. The conductive element is made by heating the sodalime glass support to 450 DEG C in a 15% by volume oxygen atmosphere in the presence of stannous chloride (SnCl2) and a fluorine dopant, which is heated to a temperature less than 480 DEG C that is sufficient to evaporate the SnCl2 and the fluorine dopant onto the support.

Title: Sealing device for pneumatic and hydraulic control instruments
IPC: F16J15/32
Filed: 1982-03-15
Abstract: A sealing device for pneumatic and hydraulic control instruments consists of a sealing ring (3), which seals a closing member (2) displaceably mounted in a housing (1). Two stops (4, 5) are provided for the sealing ring (3), one (4) of which stops is disposed on the housing (1) and the other (5) on the closing member (2). When the sealing ring (3), which can be arranged between brace rings (6, 7), is acted upon on one side by a pressure medium at (9), it is supported by the stop (5) and moves with the member (2), the ring (3) sealing against the housing (1) at its outer circumference. When the stop (4) prevents further movement of the ring (3), the latter seals against the member (2) at its inner circumference. The pressure-loaded surface can therefore be altered without using other components. The device can be incorporated in a control valve (Fig. 6, not shown) where a valve member (26) is maintained seated whether pressure medium is admitted at (27) or at (23). <IMAGE>

Title: Heat metering
IPC: G01K17/06
Filed: 1982-04-02
Abstract: In a device for the transfer and metering of thermal energy between a supply main and a consumer system, thermal contact between fluids flowing in supply and receiver ducts is effected by means of one or more thermosiphons (30), each containing a working fluid in contact with its vapour, and each having a condenser area (34) in the receiver duct, and an evaporator area (35) in the supply duct. Liquid condensate returns from the condenser area to the evaporator area through a liquid passage (42) which contains a flowrate meter (46) providing a pulsed output in which each pulse represents a quantum of fluid flow therethrough. The pulses are received by a counting and display device (48) calibrated to provide a direct reading of the quantity of thermal energy supplied. <IMAGE>

Title: Phase sensitive detector and frequency component measuring apparatus
Inventor: KEARLEY STEPHEN JOHN
IPC: G01R25/00
Filed: 1982-07-22
Abstract: A phase sensitive detector has a multiplier circuit (10-12) providing an output signal representing the product of an input signal and a predetermined switching waveform having a selected fundamental frequency. The detector includes switching means (13) arranged to form the switching waveform with 2n discrete levels (e.g. light levels), where n is greater than or equal to 2. The discrete levels are selected to minimise the amplitudes of a maximum number of lowest order harmonics in the switching waveform. A low pass filter (14) filters periodic components from said output signal. Apparatus (Fig. 3) for measuring the amplitude of a component at a predetermined frequency on an input signal comprises a pair of the above detectors, each being connected to receive said input signal as the input. The switching waveforms for said detectors have the same fundamental frequency equal to said predetermined frequency, but are in phase quadrature to one another, and a vector adder combines the output signals of the two detectors to produce a signal representing the amplitude of said component. <IMAGE>
