Patent GB-2078310-A (GB)
Title: Gas turbine rotor blade vibration damping system
IPC: F01D5/16
Filed: 1980-06-23
Abstract: The damping means consists of a passage 22, 23 within the blade aerofoil within which fits a pin which is retained to the aerofoil at its root end 26-29. The pin chunk 24, 25 is free to permit relative sliding with respect to the passage and friction between the pin and the passage absorbs energy and hence damps the vibration, the pin arranged not to be on a radius of the rotor, centrifugal force enhancing the friction. <IMAGE>

Title: Safety Barriers
IPC: E06B9/04
Filed: 1980-07-24
Abstract: A safety barrier of the type positionable in doorways, stairways and so forth to prevent the passage of small children or animals comprises a frame (1) provided on two opposite sides with clamps (9, 10, 11, 12) so that it can be secured between walls 6, 7. To permit passage of an adult there is an openable gate (13) mounted on the frame (1) by means of hinges (14, 15).

Title: Proximity detector
IPC: G01P3/481
Filed: 1981-01-08
Abstract: A proximity detector has an LC circuit in which the inductance coil 14 is to detect the presence or absence of a passing conducting part 10. The coil is powered by a variable gain oscillator 16 having a voltage output which varies according to variation of its gain control input E. An amplitude detector 18 gives a variable output which is a function of the amplitude of the oscillations in the coil, which are damped when part 10 is present. This is compared with a reference voltage from source 22 by amplifier 20 providing an output signal Vs to E to maintain the output voltage of oscillator 16 across coil 14 substantially constant. Signal Vs is of square wave form and provides an indication and measure of the proximity of each tooth (part 10) in succession to the coil. The detector may be part of an ignition system of an internal combustion engine. <IMAGE>
Patent GB-2095028-A (GB)
Title: Image correction in electron microscopes
IPC: H01J37/26
Filed: 1981-03-17
Abstract: In a transmission electron microscope the observable intensity of electrons passing through a specimen contains information about the amplitude of the wave function but not its phase. The invention provides this phase information by recording the intensity distribution with and without an apodizing filter 20 in the electron beam path and processing these two distributions to retrieve the phase. This filter e.g. of carbon, has a thickness which varies in a manner so as to produce an exponential factor of exp(-2 pi at) to the amplitude of the transmitted wave function and a linear factor to the phase of the wave function, e.g. as shown, it may be a linear wedge. <IMAGE>

Title: Warning light for electric cookers
IPC: H05B3/74
Filed: 1981-08-07
Abstract: A glass ceramic top electric cooker having discrete cooking surfaces heated by radiant heaters includes warning means to indicate when one or more of the cooking surfaces is above a safe touching temperature of about 50 to 60 DEG C. This is achieved by arranging the radiant heaters (1) (not shown) against the underside of the glass ceramic top (10) such that an enclosed chamber (11) is formed between the housing of the heater and the underside of the glass ceramic top. An opening (19) is formed in the housing of the heater which enables hot air to flow out of the enclosed chamber when the heater is energised. A thermally responsive element such as a bi-metallic switch (16) is located adjacent to the opening and is connected to operate a warning lamp when the bi-metallic switch is actuated. <IMAGE>

Title: Apparatus for vaporising a liquid by hot compressed gas to produce power
Inventor: KERSHAW HERBERT ARTHUR
IPC: F01K21/04
Filed: 1981-11-26
Abstract: In the single cylinder four stroke piston engine shown, a gas, for example air, drawn into cylinder 3 is compressed and water is sprayed into the compressed gas by injector 9. The water is immediately flashed into steam, giving a sudden pressure rise in cylinder 3 which drives its piston downwards, thus turning the engine's crankshaft. The mixture is finally exhausted from cylinder by pipe 10 to atmosphere or alternatively, via pipe system 12 into a condenser 6, which recovers water from said mixture, and fresh air or mixture led back from said condenser is again admitted to said cylinder. A mechanical pump 7 driven by the engine, supplies the water under pressure intermittently to injector 9. An embodiment incorporating a jet-pump compressor and a turbine instead of the piston/cylinder engine is described, Fig. 3 (not shown). <IMAGE>

Title: Improved time slot arrangements for local area network systems
Inventor: BEAUFOY RAYMOND
IPC: H04Q11/04
Filed: 1982-08-04
Abstract: In local area networks (LAN's) which are required to operate in duplex mode it is necessary for the common communication medium to be operated in a t.d.m. manner. Because the LAN has no common equipment, every station is arranged to contain its own control circuitry and crystal controlled clocking system to produce time slot markers. The system is organised so that each time slot comprises an active period for data or speech transmission or contention resolution, followed by a transit period in which the data or speech reaches the destination. Ideally time slot markers occur simultaneously in both stations and for intermediate stations there is a tolerance which reaches a maximum at the midway point of the network communication medium. The multiplexing system arranges that the time slots are packed as closely together as the delay between most separated stations will allow. The near simultaneous occurrance of time slot markers is maintained by all stations whether busy or free by observing the timing of traffic on the communication medium and adjusting the timing of the station time slot marker to occur in the time between data or speech bursts of existing traffic.
