Patent FR-2297651-A1 (FR)
Title: Game for two players using moving counters - advanced or retreated over squared board to take opponents pieces
IPC: A63F3/02
Filed: 1975-01-14
Abstract: The board comprises ten rows of nine squares, some squares being marked by a coloured border. Two differently coloured sets of nine counters are provided and each counter is square and double faced, one side having one band and the other, two. Each set is ranged at opposite ends of the board and move forwards or backwards 1 or 2 squares each time, but not sideways. Counters can move back to benefit others, which can move an equal number forwards. A player landing on an occupied square removes that counter. When reaching the opponent's camp, counters are reversed and the counters can also move sideways.

Title: Fire escape stairway with vertical core frame support - is built of floor height modules each with three straight flights forming equilateral triangle
IPC: E06C9/02
Filed: 1975-03-10
Abstract: The stairway for use as a fire escape is supported on a vertical core frame (2) of polygonal cross-section, utilises straight flights at eg. 60 deg. w.r.t. one another in plan, and is built up from the base in floor height modules.

The core frame is mounted on a single column at ground level. The treads may be of uniform width (22) and span lengthwise between the core (2) and the staircase exterior (28). Each module may have to intermediate landings (16, 17) of isosceles pentagon shape, and two terminal landings (15,18) which serve as floor accesses.

Title: Excitation coil cct. for DC contactors or relays - has electronic switch for pulsed voltage supply to excitation coil in holding state
IPC: H01H47/32
Filed: 1975-04-24
Abstract: The excitation coil circuit for direct current operated contactors or relays is so arranged that during the holding phase the feed voltage is upplied to the excitation coil via an electronic, contactless switch or a transistor. Preferably the frequency and/or the duration of the pulses is control in dependence on the holding current measured at voltage drop across a measuring resistor. During the attraction phase the pulse generator is bridged for the transit time of a resistor-capacitor element, or in dependence on the current flow in this attraction phase. If the frequency and/or duration of the pulses is controlled by a measuring resistor, the bridging of the pulses generator may be attained by short circuiting the measuring resistor.

Title: Window mounted motor vehicle antenna - has preamplifier operating over twenty kilohertz to one hundred megahertz band
Inventor: ROSELLI SERGIO
IPC: H01Q23/00
Filed: 1975-05-06
Abstract: A windscreen or window mounted antennae for motor vehicles gives a signal level great enough to allow high fidelity with a low noise level. The antennae itself uses a printed conducting tape extending along the perimeter of the glass surface spaced a short distance from the metal surround. The conductor is folded and includes a short vertical element at the antennae centre the dimensions being chosen to provide reception over the 20kHz to 100kHz band. The antennae itself is terminated in a printed impedance and a connector. This feeds a wide band preamplifier supplied by 12 volts by a conductor running in parallel with the outer screen of the coaxial cable connecting it to the receiver itself.

Title: Stator or rotor for electrical machine - is made from stack of comb shaped strips bent into circle
IPC: H02K15/02
Filed: 1975-07-03
Abstract: A ring shaped stator or rotor for an electrical machine, particularly for a vehicle generator is made from a stack of metal strips which are stamped from metal sheets, to give a set of comb shaped strips. These strips are straight, and are all identical. The strips are stacked to a required thickness and bent over a circular sector with any angle up to 360 deg., whose axis is perpendicular to the lamination plane, to form a ring. These strips are bent into a circle around a toothed wheel (7) by using pegs (10) which fit between the teeth of the strips and which are engaged by the toothed wheel.

Title: Invalid chair lifting mechanism - has hydraulic rams on side frames thrusting downwards onto floor
Inventor: BONFIELD ROBERT B
IPC: B66F3/46
Filed: 1975-07-25
Abstract: The mechanism fits on the side frames (4) of the chair and incorporates hydraulic rams (12) extending downwards so as to bear against the floor (21) and thus raise the frames to a convenient height for the occupant to work at a table, kitchen stove etc. The rams can actuate extending frames with bars (21) resting flat on the ground, and the rams can be supplied by a hand pump and connected in series so that they extend and retract for an equal amount. As fluid is delivered against one face of one ram piston, the other face forces fluid out of the ram to the other ram, which in turn returns fluid to the reservoir or to the pump.

Title: Projectile fuse rotor safety spring clamp - has curved arms and thin web ensuring releeleeleasing under radial forces
Inventor: RENTZSCH MAX
IPC: F42C15/22
Filed: 1976-09-06
Abstract: The projectile fuse has a housing with a rotor. The rotor has seats for initiator and grooves for a clamp for holding the initiator and rotor in safety position. The rotor is readily moved into the armed position. High functional reliability is ensured by the special shape of the holding clamp. The clamping safety element (12) has two radially curved arms (18, 19) connected by a curved web (20). The inner curve (18a, 19a) of the two arms (18, 19) matches the form of the groove in the rotor. The outside curvature (18b, 19b) matches the diameter of the groove in the support body. The curved web (20) has a smaller cross section than that of the arms. This ensures that radial forces cause a uniform deflection of both arms (18, 19).

Title: Electronic monitoring and recording system - has auto-adaptive memory whose capacity is less than numbers of events to be monitored
Inventor: NOWAKOWSKI JEAN
IPC: G06F7/78
Filed: 1977-04-29
Abstract: The supervisory and recording system is designed to monitor a number of fleeting events relative to physical magnitudes. The system has counters which transform the physical magnitudes into analogue signals and circuits which sample the analogue signals. The sampled signals are converted into digital magnitudes which are sent in real time to a fast memory. The system has a slow rate recording element and means for transferring in different time the memory contents to the recording element. The system has a memory having a capacity which only permits it to memorise a small number of events which are less than the number of fleeting events. The memory has processing elements which, in response to an event which occurs when the transfer of numerical magnitudes representative of the preceding event is not terminated, inscribed in the memory of the new event. The new event is sent to addresses already occupied by the preceding event. These addresses are regularly distributed with a predetermined periodicity.

Title: Prepn. of a diene hydrocarbon with concurrent catalyst recycle - by oxidising dehydrogenation of an alkane or alkene, e.g. (N)-butane
IPC: B01J8/38
Filed: 1977-08-25
Abstract: Prepn. of a diene hydrocarbon comprises oxidising dehydrogenation of an alkone or alkene at 400-700 degrees C in the presence of an inert diluent and an oxidising agent in a fluidised bed of an oxide catalyst. The reactor contains >=2 sections which are divided vertically and communicate in the upper and lower parts of the fluidised catalyst bed. The bed circulates in a predetermined direction from section to section. It is reduced during the reaction while its movement is co-current with the hydrocarbon feed. Reaction products are desorbed upon counter-current movement of the bed with inert diluent, and the bed is oxidised to regeneration by co-current movement with oxidant. Used for prepn. of butadiene isoprene, etc. The process is simple and avoids large catalyst losses. It is cheap and can be performed industrially.
