Title: Divided power circuit breaker for energy supply systems - has several electronic switches for each output terminal for coupling different input terminals (NL130776)
IPC: H02J9/06
Filed: 1976-01-09
Abstract: The circuit breaker connects the input and output terminals of a power supply system which has two input terminals and a number of output terminals for corresponding number of loads. Each output terminal (12) has an associated switching system (13) for connection to the respective input terminal in the desired mode. Each switching system becomes effective on failure of its first power source, in order to connect automatically the associated output terminal to a second power source. Each switching system has an impedance (15) of preset value, which is incorporated between one input terminal and the output terminal associated to that switching system. A second impedance (16) has a greater value than the first one and is incorporated between the other input and the respective output terminal.

Title: Bore formation to fine tolerances - using liner on core cylinder and bedded inside bore of two-shell housing
IPC: B23P15/00
Filed: 1976-02-17
Abstract: The process for fabricating a long circular section hole to fine tolerances uses a liner which is pressed onto a two shell housing. A bedding compound is used between the liner and the housing bore. The liner, in sheet form, is wrapped round a cylindrical core. The dia. of the core is equal to that required in the finished hole. Circumferential beads of the bedding compound are then placed on the exterior of the liner, and finally the two shell housing is placed onto the core-liner assembly. The bedding compound may be silicone and once it has set, the core is removed.

Title: Smoking attachment for domestic baking oven - includes hot plate pan and vent for food smoking operations
Inventor: BLANQUET GEORG V
IPC: A23B4/052
Filed: 1976-02-23
Abstract: A domestic baking oven has built-in or detachable fitments to make it suitable for use as a smoking chamber for food. A hot plate receives the sawdust either directly or on a pan; the oven ceiling includes a flue vent with a danger to extract the smoke. This saves the space, which is usually not available in a domestic kitchen, for a separate smoking chamber.

Title: Electrical capacitor with overload protection - has disc operated by pressure with deflection used to cut wire (SW030177)
Inventor: NIELD FREDERICK ARTHUR
IPC: H01G2/14
Filed: 1976-06-03
Abstract: An electrical capacitor has a cut-off which operates when overload is applied and has a metallised polypropylene winding (1). The winding (1) is in an aluminum case 3) sealed by an ethylene-propylene disc (7). During overload, pressure can build-up inside the case (1) and the middle part (9) of a resin coated paper disc (8) can move with a deflection of the disc (7). A wire (12) is connected between a terminal (11) of the capacitor and the winding (1). The wire (12) passes through a hole (14) with a sharp edge. On deflection of the disc (7), the wire (12) is cut.
Patent FR-2367939-A1 (FR)
Title: Bearing for rotating shaft utilising magnetic repulsion - has shaft and housing with radial alignment of magnetic poles
IPC: F16C39/06
Filed: 1976-10-12
Abstract: A hollow shaft (2) is made of magnetic material in such a way that the whole of the outer surface forms the north pole and the bore forms the south pole. The bearing sleeve (4) is made in a similar manner but with the polarity reversed. This results in a magnetic repulsion between the bore of the bearing sleeve and the surface of the shaft. This magnetic repulsion keeps the shaft central in the bore of the sleeve as any tendency to move to one side increases the repulsive force on that side. Using a shaft of 99 mm dia. in a sleeve of 100 mm dia. by 20 mm wide, the centering force reaches 80 daN when the shaft touches the bore.
Patent FR-2368913-A1 (FR)
Title: Leather goods pocket construction - consists of sheet fixed to base by half bellows sewn onto edge of base
IPC: A45C1/08

Abstract: The pocket which is for use in leather goods, such as the internal pocket of a wallet, consists of a sheet (1) fixed on to a base (2). The pocket is made by fixing some half bellows (5) to the lateral edges of the sheet and the base. The sheet is trapezoidal in shape and the half bellows are stitched to its lateral edges, on its external face. These edges are then folded (8) internally and the half bellows are sewn on to the edge of the base to form the bellows of the pocket.

Two arches form a modular component and allow the fitting of struts and cladding panels. The assembly of several modular components together allows the dimensions of the vehicle body to be varied. The arches can be of tubular section and mounted on a frame fixed to the chassis at their free ends. The struts can be mounted in the top arch corners, to form part of the vehicle roof, and being radiused to form the rounded side ridges of the roof.
Patent FR-2336003-A1 (FR)
Title: Phase control loop for oscillator - is used as phase shifter for generation of phase shift between oscillator and other frequency
IPC: H03K5/13
Filed: 1976-12-20
Abstract: The frequency generated by the oscillator and the frequency with which it is to be synchronised are divided in the same ratio and are compared in a phase discriminator. The output signal of the phase discriminator is used for oscillator control. The phase difference is adjusted by varying a component in the timing circuit. The system may also operate by varying the oscillator control voltage within the holding range of the phase control loop. A phase detector (2) is connected via a low pass filter (3) to an analogue adder (4). This in turn is connected to a VCO (5), connected to a frequency divider (6). This frequency divides together with a similar frequency divider (2) from the inputs to the phase detector (2).

Title: Air and fuel metering system for IC engines - has air intake with vortex shedding flowmeter to produce fuel regulator signals
IPC: F02D41/18
Filed: 1977-01-14
Abstract: Air intake (4) contains a vortex shedding flow metering unit (8) to produce electrical impulses with a frequency proportional to the air flow volume. The output is fed to a control circuit (12). The circuit integrates information concerning engine speed (14) air intake temp. (16) battery output (17) and engine cooling medium temp. (19). The electronic regulator produces a corresponding series of square wave impuses of predetermined dwell (18) to effect the exact fuel dosage to a fuel injector (20). The impulse dwell is primarily determined by the air intake volume and modified by engine working conditions. The fuel injector ball valve is vibrated at ultrasonic speed by a piezo electric crystal to spray the fuel into the inlet manifold. A heater pipe (30) connecting the exhaust manifold (34) with the inlet manifold and containing a vaporisable material such as sodium is fitted opposite to the spray jet to assist vapourisation.

Title: Appts. for stepwise advance of welding rod - has slide box mounted in support, a hollow slide inside first slide and movable walls
IPC: B23K3/06
Filed: 1977-05-03
Abstract: Appts. to advance a welding rod stepwise comprises a slide block mounted in a support, a hollow slide pieced inside the first slide and movable longitudinally, the front and rear walls of the hollow slide being apertured for the passage of rod which is coiled on a second support, the coil being located rearwardly of the slide.

Title: Rotary radial piston IC engine - has stationary casing with ports which sequentially register with open ends of cylinders
IPC: F01B13/06
Filed: 1977-10-28
Abstract: The engine has a cylinder block (1) with three cylinders (2, 3, 4) arranged radially. There is a piston reciprocating in each cylinder and connecting rods from all the pistons are joined to a common crank (6) on a crankshaft (8). An outer casing (5) surrounds the cylinder block. The cylinders have open ends which slide on the inside of the casing. The reciprocating of the pistons about a common crank causes the cylinder block to rotate within the casing. The casing contains ports (9) as well as fuel injectors (10) and sprking plugs (11). The casing with the ports eliminates the need for reciprocating valve mechanisms.
