Title: Drive for angular velocity sensor in vehicle anti-skid system - uses gearbox final drive or tachometer drive
IPC: B60T8/171
Filed: 1975-08-08
Abstract: A drive for angular speed transducer is used as part of an anti-skidding breaking system for road vehicles. The transducer has a stator and a rotor which rotates with respect to the stator such that an electromotive force is induced in a winding. This electromotive force is oscillating with a frequency which increases and decreases proportionally with any increase or decrease of the angular speed. This electromotive force is used to actuate an anti-skidding device when the deceleration is greater than a set value. The drive also has a shaft with a gear wheel. The shaft has an extension with another gear wheel which drives a tachometer by means of another gear wheel.

Title: Self acting compressed air engine - has reciprocating inner cylinders compressing air inside stationary outer cylinders with four stroke action
IPC: F01B1/00
Filed: 1975-12-09
Abstract: The engine has four fixed cylinders. In place of a piston each has an inner cylinder which reciprocates within it. The bottom of each reciprocating inner cylinder is joined by a connecting rod to a crankshaft, the four cranks being angularly displaced from each other. Each inner cylinder has a floating piston within it which is moved by air pressure. The fixed cylinders have valve openings through which an initial charge of compressed air is introduced. This starts the engine and then on each stroke two cylinders provide the driving force while the other two are compressing a fresh charge of air. The engine thus continues to run without further supplies of fuel or energy.
Patent FR-2315892-A1 (FR)
Inventor: CIMBALI MARIO
IPC: A47J31/46
Filed: 1975-12-11
Abstract: An essentially constant water level is to be maintained in the boiling vessel by means of this apparatus. The latter has a removal tap and a supply tap (1 and 2, respectively) and a lever (22) which is intended for simultaneous, and independent, actuation of these taps (1, 2). The lever (22) can be pivoted about an axis running perpendicularly to the longitudinal axis of the lever (22) and can be displaced parallel to said longitudinal axis. The lever bears a number of pins (24, 26, 28) at a distance from its pivot axis and one pin (41) arranged level with the pivot axis. These pins (24, 26, 28, 41) act on pivotable intermediate members (30, 31) which, for their part, act on actuating push-buttons (3, 4) which control valves arranged in the taps (1, 2). Both taps (1, 2) are opened at the same time by pivoting the lever (22) downwards, whereas only the supply tap (2) is opened by pivoting the lever upwards. The opening of the removal tap (1) alone is achieved by pressing the lever (22) in.

Title: Flame photometric analyser for detecting contaminants in oxygen - with remote photomultiplier, allowing higher operating temperatures and increased sensitivity
Inventor: MOREAU MICHEL
IPC: G01N21/72
Filed: 1976-03-04
Abstract: Flame photometers detect contaminants in oxygen-contg. gases. Such appts. incorporates a burner and an analysis unit. The burner is housed in a space into which hydrogen is passed and reacts in two stages with the oxygen-contg. gas. The analysis unit incorporates a photomultiplier which sees, through an interferential filter, the flame produced in the first stage, i.e. when hydrogen is in excess in relation to the oxygen in the gas. The burner housing is heated to >=100 degrees C. generally 120 degrees C and the photomultiplier is mounted remote from the housing and connected to it optically by a light pipe of optical fibres. The interferential filter is placed at the end of the pipe at the entry of the photomultiplier. The invention allows the operating temps. to be increased without affecting the photomultiplier. The ability to operate at higher temp. increases the sensitivity of the appts. partic. to materials of low volatility.

Title: Wind powered turbine for energy generation - has impeller with centrifugal blades and decompression flaps closing impeller at high wind speeds
IPC: F03D1/00
Filed: 1976-05-06
Abstract: The turbine has an impeller on a shaft parallel to the wind. The impeller is in the form of a drum with an open inlet and with radial centrifugal blades perpendicular to the shaft between the inlet and the back of the impeller. The back of the impeller is formed by flaps held by cables they are shut by springs and opened by excess wind pressure. At moderate wind speeds they close the impeller drum so that wind blowing in is compressed by its own kinetic energy and then expands through the centrifugal blades. At high wind speeds the flaps open to prevent overloading. The whole turbine is mounted on a pivoting chassis which can be turned into the wind.

Title: Elastic buffered mounting for train bogey - with two pairs of pads for asymmetric suspension of pivot housing
Inventor: GEERS LEO
IPC: B61F5/30
Filed: 1976-06-04
Abstract: The train bogeys are pivoted on the supporting frames of the train suspension by conical kingpins (1d) which locate in conical housings (1a) with elastic rings as buffers between. The conical housing is further braced on the frame by special elastic pads with one of the sets of pads (3) arranged to compress under pressure and distort through lateral forces. The pads are aligned so that the lateral forces cause less distortion than do the longitudinal forces. The pads are further reinforced by other pads (4) set to compress under lateral distortion. The bogey is thus sprung for maximum lateral stability while preserving a compact, low profile suspension.

Title: Independent freezer monitoring unit - comprises external thermostat with alarms and sensor head extending inside
IPC: F25D29/00
Filed: 1976-07-02
Abstract: The independent monitoring unit is for deep freezers, cold rooms etc., indicating any abnormal rise in temp. A temp. control thermostat is supplied directly from the mains or batteries, mounted on the outside, with its head inside the deep freezer etc. This initiates one or more audible alarms or lamps mounted on it, and an interrupter or other cut-out switch is connected in series with the alarms, giving momentary interruption of them at intervals until the freezer resumes normal operation. The thermostat can have a quick-action mounting, securing it detachably or permanently to the freezer. The alarms and interrupter can be mounted together in a housing separate from the freezer.

Title: Light modulator for cine film projector - has two right angle diaphragm blade segments driven on parallelogram linkage to define variable square aperture
Inventor: GROSSETETE ROGER
IPC: G03B9/06
Filed: 1976-09-07
Abstract: The light modulator has a diaphragm which has two occulation strips (1, 1') whose adjacent parallel edges define a slot. These strips are mounted so that they rotate at their ends (2, 2') on mobile pivoted around fixed axes (0, 0'). The arrangement of the strips (1, 1') and the elements form a deformable parallelogram. One of the mobile elements can be rotated via an element which meshes with a driving element (10) which rotates around the same axis as the mobile element. The driving element (10) has a stud (12) which fits into a circular slotted cam (14) carried on a control element. The control element rotates around a fixed axis situated in the extension of the path followed by the stud at the moment of displacement by the driving element. This ensures that the stud (12) can only be displaced under the effect of a displacement of the cam.

Title: Electromagnetic valve for diesel engine fuel injection - has pressure balanced plunger to reduce solenoid force and admit fuel to engine
IPC: F02M51/06
Filed: 1976-09-17
Abstract: The electro-magnetic valve for fuel injection for diesel engines has a cylindrical body (1) with a fuel inlet (3) connected by the pipe (4) to a pump. The fuel is injected into the engine cylinder through the orifice (5) and surplus fuel is returned through the pipe (14). The orifice is normally closed by the tubular plunger (44) which is pushed downwards by the spring (39). The fuel pressure is exerted on all the external faces of the plunger so that it is hydrostatically balanced. When the solenoid (6) is energised it attracts the head (18) of the plunger and lifts the lower end off the valve seat (32) to admit fuel to the engine. Because the valve is balanced the solenoid has only the force of the spring to overcome.

IPC: E04D3/32
Filed: 1976-10-21
Abstract: Seen in plan view, the profiled roofing slab is of an essentially angular shape. Seen in a plan view of the roofing slab (21, 22, 23, 24), a prefabricated bevel (25) is configured on at least one corner of said slab and a prefabricated recess (26) is configured on at least one side edge of said slab, in order to form a prefabricated angular section.
