Title: Preparing metal coatings
IPC: C23C16/02
Filed: 1979-05-29
Abstract: A process for coating a solid substrate material, e.g. a carbon fibre, with a uniform layer of a valve metal or compounds thereof including nitrides, carbides or carbonitrides.

Title: A Process for Measuring Fuel Consumption by Periodical Weight Measurements Mainly for Testing Internal Combustion Engines
IPC: G01F23/20
Filed: 1980-05-27
Abstract: In a process for measuring the fuel consumption of an internal combustion engine M, the interrelated values of the weight of the fuel consumed, the time taken to consume the fuel and the number of revolutions of the engine performed during this consumption are measured. After commencement of the measuring process, the weight of the fuel consumed and the time taken to consume it from the start of the measurement are repeatedly measured, either continuously or at predetermined time intervals or weight steps, and these values are compared with predetermined limiting values of the minimum weight of fuel to be measured and with the minimum time of measurement. When both limiting values are reached the measurement is terminated and the result is obtained from the last-measured related set of values of fuel consumed, duration, and the number of engine revolutions. The weight is measured by a balance G which provides one input of a measuring unit m that has further inputs from a revolution counter N, a clock T and a control unit v. The measured values are stored in a store t, computed in an arithmetic unit a, and displayed in a display unit D. <IMAGE>

Title: Radiant energy collector panels
IPC: F24S10/80
Filed: 1980-10-14
Abstract: The radiant energy collector panel (10) has a body (14) defining a fluid inlet port (16) and a fluid outlet port (32). The body includes a heat collector (18) consisting of a thermally-insulating porous matrix material having a unitary, mass-enclosing surface and bulk macropores. The walls of the macropores define tortuous fluid passageways in the body, and distinct elements are discretely disposed on the walls of the macropores throughout the matrix material. The distinct elements have a high degree of absorptivity for radiation and low emissivity for long-wave radiation. A first flexible member (24) overlies the porous body and forms a collection chamber therebetween. A second flexible member (28) overlies the first member and is spaced therefrom. These first and second members are essentially transparent to incident radiation and substantially opaque to radiation emitted by the porous body. <IMAGE>

Title: A drive mechanism for use in apparatus for playing a game of chance
IPC: G07F17/34
Filed: 1980-10-17
Abstract: A fruit machine reel signals a number of datum positions A-E for each revolution, and the symbol at which the reel is to stop is pre- selected and identified by its distance from one of the datum positions. The pre-selection is used to govern a stepping motor drive. The datum positions are coded, the favoured arrangement being elements unequally circumferentially spaced around the reel and each in turn producing a pulse at a single sensor. The pulse spacing, in terms of steps of the motor from one datum to the next, identifies each datum. Apart from one datum providing an origin from which the stopping position is reckoned, usually the first datum identified, the other datums are used to keep a check on the reel rotation. <IMAGE>

Title: Demodulator
IPC: H03D1/22
Filed: 1981-06-09
Abstract: An AM demodulator includes a phase-locked loop 6-14 for maintaining the tuning frequency, the loop including an integrating circuit 12 responsive to a phase error signal for controlling a voltage controlled oscillator 6. The output of the integrating circuit 12 has a component proportional to the error signal, and another component proportional to the integral of the error signal which, in the steady state, is zero. The demodulator thus stays tuned during temporary loss of a pilot carrier signal. The demodulator is particularly useful in short wave and medium wave receivers for reducing the effects of multi-path interference. <IMAGE>

Title: Distinguishing signals from noise
Inventor: GODDARD GRAHAM CLIVE
IPC: G01S13/524
Filed: 1982-03-22
Abstract: A signal receiver, for use on a Doppler radar system for example, disciminates between coherent received signals and background or other noise, on the basis only of the phase of the input signal, rather than its amplitude. The output of a given Doppler filter 11 is supplied via a hard limiter 12, which detects the zero crossings, to a monostable 13. A low-pass filter 14 detects the mark-space ratio in the monostable output, which ratio will vary randomly when only noise is being received but will become steady when a coherent signal (i.e. of regular frequency) is present. Filter 15 blocks such steady outputs, so producing a signal E which remains steadily at zero when a coherent signal is present. This condition is sensed by a threshold detector 16 which provides a logic 1 level when signal E is substantially zero and whose integrated (17) output will thus rise above a threshold (18) only when E remains at zero for some time. Large reflected signals interfering from adjacent Doppler frequency bands are blocked by network 21- 23, and a signal representing Doppler frequency is derived at 24. <IMAGE>
