Title: Random number generator for amusement machine - using two counters supplied by respective frequency generators, and matrix
IPC: G07C15/00
Filed: 1973-11-27
Abstract: The random number generator, for an amusement machine simulating a game of roulette or cards, or horse racing, employs two counters with differing total count values and supplied by two respective frequency generators (F1, F2) which are connected to a common control circuit. The counters are connected to respective decoders, having the same number of outputs as the number of count positions of the associated counter, with the first counter used to validate one line of a matrix and the second counter one column of the matrix. The latter matrix may be square or rectangular with the number of lines determined by the required representation and the number of columns determining the probability of obtaining a number.

IPC: B29D7/00
Filed: 1974-01-18
Abstract: In the prodn of flexible cellular plastics from chlorinated polymers by heating a blend of chlorinated polyethylene and/or opt. after-chlorinated PVC and blowing agent (I) in a gas-tight closed zone with no gas space at temps above the softening point of the polymer and above the decompsn. point of (I) releasing the press and foaming the mixt the outer zone of the blend is cooled before the press is released. These foams can be used in automobile construction for boat, head and side linings and as packing; for filling joints; as thermal insulant; in the form of metal composite sandwich as cladding for facades; and for packaging purposes. They have better flame retardancy and thermal stability than familiar foams; fine cell structure; better mechanical properties; low thermal conductivity; sealed outer surface, giving improved wear resistance; and better resistance to impact. The temp. drop from the inner to the outer zone is 10-100 degrees C.

Title: Automatic paper strip coiling mechanism - passes incoming end of strip between spool and belt partly enclosing it to start wrapping action
IPC: B65H18/22
Filed: 1974-09-06
Abstract: The spool is mounted inside a freely moving endless conveyor belt running over rollers, and the belt can be swung against the spool so as partly to encircle it. The forward end of the strip of material passes between the belt and the spool, and so is positively pressed against the latter. The rollers can be mounted on a plate in two parts and are nearly ring-shaped. They are swung together and are moved apart by pneumatic actuators. Some of them can be spring-mounted in the radial direction, and the belt can enclose the spool for between 180 deg. and 300 deg. The belt has the effect of wrapping the paper strip around the spool so as to start the coiling process.

Title: Colour television camera with integrators - uses integrators to control black reference level of each colour together with lineariser and reference voltage
Inventor: RONSIN PIERRE
IPC: H04N5/16
Filed: 1974-11-28
Abstract: The colour televison camera produces a video signal from each image tube, each signal contg. a black reference level which is adjusted as a function of the average image luminance. For a particular colour component the image passes through the objective lens, a colour-filter separation unit and onto the faceplate(19) of an image tube(16). Part of the scanned image is kept at reference black(20), resulting in a black reference level in the video signal. After amplification(23) and linearisation(24) the video signal is output(26). An integrator(33) taps this output, passes the average luminance level in the video signal to a lineariser(38) for comparison(44) with a reference voltage before being used, synchronised by the image tube scan signal(55), to adjust the black reference signal(32).

IPC: F03D5/04
Filed: 1975-01-08
Abstract: The power generation system consists of a large number of railway wagons coupled end to end. Each wagon carries a number of aerofoil blades mounted on vertical shafts. The wagons are divided into two groups, one group running on an inner loop of railway line with the blades aligned to run in one direction. The other group of wagons with blades aligned to run in the opposite direction. A guide track between the railway lines engages a roller so that the blades change their angle of attack as they move around the curve at each end of the railway line. About 8000 hp can be generated using 50 wagons.

Title: Electric motor starting using generating set group - involves using variable voltage which reduces start current by factor of 3 with respect to normal methods
Inventor: MICHELIER GEORGES
IPC: H02P1/32
Filed: 1975-03-13
Abstract: The method of starting an electric motor from a generating set group uses a voltage variation technique. It utilises a star-delta type system. The generating plant group (1, 3) is first coupled in 'delta', so as to supply the smallest possible voltage and then connected in 'star' to supply normal voltage. The starter (4) consists of an housing in which is fitted an inverter. Into the starter (4) are connected the six output (U, V, W, X, Y, Z) connections of an alternator (1-3) on generator of the group. The connections are arranged such that they are connected in delta for starting, then into 'star' for normal operation several seconds after starting. The system is suitable for diverse power generating set groups, and in particular for immersed electrical pumps fed from 3 phase 220/380 volt supplies.

Title: Snow permittivity measurement for avalanche forecasting - uses probes for measurement at two frequencies with thermistor for temp. determination to calculate water content of snow
IPC: G01N27/22
Filed: 1975-10-02
Abstract: Measurement of permittivity of snow at two different frequencies together with temperature measurement enables avalanche risk to be forecast. Probes with electronic measurement and control circuits are arranged at particular depths in snow. Each probe contains a thermistor in a bridge circuit with a potentiometer and galvanometer permitting direct reading of snow temperature. Permittivity is measured by connecting a measuring capacitor and balancing capacitor to two oscillators in turn. A motor varies the balancing capacitor for balance on the galvanometer connected to discriminator outputs. The motor also drives a potentiometer producing a voltmeter reading which enables density and water content to be determined.

Title: Lighting effects modulated by sound signals - are proportional to sound intensity and frequency and introduced by smooth changes with time delay
IPC: A63J17/00
Filed: 1975-10-16
Abstract: The system provides lighting effects in accordance with sound volume and the acoustic frequencies. The change between colours is smooth and a time delay can be fitted to increase the effects produced. Three identical channels are used; bass, medium and high producing red, blue and green lights respectively. These reconstitute to white. A negative channel may be used for yellow. The pilot signal enters (1) the system and is regulated by a potentiometer (2). The signal is fed to the three filters (3) and a suppressor (4). The transistor (8) amplifies the pilot signal, passed through variable resistances to a phase modulator. The signal passes through a triode (19), triggered to control the lights (20).

Title: Silent action magnetic lock - has supple membrane between lock contact faces and lock parts may be of ferromagnetic powder impregnated elastic material
IPC: E05C19/16
Filed: 1975-12-01
Abstract: The relatively quiet magnetic lock has an supple membrane lining the non-magnetised contact face. Alternatively, the mahor magnetic or non-magnetic lock components may be of an elastic material filled with ferromagnetic metal alloy powder. The presence of the supple or elastic material reduces the sound as the mutually attractive lock components come into contact at door closure. The membrane has an adhesive face, is bonded to either of the lock components, and may also be of powder impregnated elastic material. In the latter case the membrane maybe simply fixed to the magnetised lock component by magnetic attraction. As a further alternative the powder may be of a permanently magnetic nature and constitute the active lock component. The lock components may be mounted on an elastic noise absorbant layer.
