Title: Pneumatic accumulator storing energy derived from wind - enables high pressure to be derived from low torque machine
IPC: F03D9/02
Filed: 1975-03-04
Abstract: A wind driven machine drives an air compressor which draws in air at pressure from the atmosphere through a valve (Z1). Air is delivered through the valve (Z2) and through the slide valve (S1) to the receiver (R') and through the non-return valves (CL1) to C65) to all the receivers (R") to (R"""). When the pressure rises, the slide valve (S1) is pushed upwards so that air is drawn from the receiver (R') and delivered to the receiver (R") until a higher pressure is achieved. The slide valve (S2) is then actuated and the process repeated until the receiver (R""") is charged to a maximum. In this way a very high final pressure can be achieved from a low torque winddriven machine.

Title: Sewer treatment method to prevent blocking by roots - involves injecting herbicide into blocked-off section of sewer
IPC: B08B9/04
Filed: 1975-03-25
Abstract: A method fo introducing a herbicide into sewers and drains which are in danger of becoming clogged by roots etc. and which are normally inaccessible involves introducing an inflatable plug (3, 31) into each end of a section to be treated. A spray nozzle n8) carried by a suitable device at the end of a supply tube (6) is inserted as far as the remote plug (31), then a foam (9) containing the herbicide is injected into the section (1) as the nozzle is withdrawn. The substance is pumped through the tube (6) from a pump (5) on the surface, and the tube passes over a drum (7) nearby. AFter a suitable delay, the plugs (3, 31) are removed.

Title: Device for irradiation and measurement of a cylindrical fuel element - designed for introduction into a swimming pool test reactor
IPC: G21C1/30
Filed: 1975-04-18
Abstract: The device comprises a closed chamber extended at its upper end by a tube. Both the chamber and tube are designed to receive the fuel element (e.g. of a fast neutron Na cooled reactor) and are of greater dia. than this. They are filled with a fluid identical to that used in the nuclear reactor. Arrangements are made to maintain the fluid at the temp. at which it will subsequently overate in the reactor. Means are provided for the controlled displacement of the fuel element from the closed chamber to the upper end of the tube and for measuring the diameter of the element when it has been brought into the tube. Pref. means are also provided for rotating the fuel element round its longitudinal axis. System enables a large number of tests to be made on a fuel element to determine e.g. the tendency for its tubular sheat to swell, under conditions which are the same as it will be subjected to in the actual power reactor.

Title: Dosing device for agar medium on glass - for measurement of low concns. of antigens or antibodies
Inventor: AVRAMEAS STRATIS
IPC: G01N33/48
Filed: 1975-06-12
Abstract: Dosing device for an agar-agar medium is notably intended for the immunoenzymatic method for measuring low concns. of antigens or antibodies; it comprises a support plate and a box with a rectangular base with rounded corners and lateral walls. The assembly is made from a rigid, moulded plastic material which may be transparent, translucent or opaque. Hemispherical feet are provided on the underside of the base to isolate it from the surface on which it is placed. A pliable, moulded, plastic cover is supplied which is a perfect fit for the box and it can remain air-tight for a min. of three days. A passage connects the space between the base and the plate with the exterior. After sterilisation at 120 degrees C, in an autoclave, an agar-agar gel is cast on one of the faces of the glass plate, to a thickness of 1.5 mm. The plate is turned over the placed facing the base of the box where it rests on the rims and the studs. The end of a pipette, filled with the reagent, is introduced into the passage; the cavity is filled until the liq. comes into contact with the gel into which it diffuses by capillarity. The lid is then placed in position. If the box if transparent material, the gel can be examined at any time by turning the box over. The fragile gel is well protected against the entry of impurities and the harmful effect of dehydration; manipulations between successive doses are reduced to the min.

Title: Safety device for road vehicles in crash - has linkages transmitting impact force to switches which cut out battery and alternator
IPC: B60K28/14
Filed: 1975-06-20
Abstract: The safety device for road vehicles in a crash automatically cuts off the current from the alternator and from the battery after a severe shock, so reducing the risk of fire. The device is held in a container and a linkage transmits the force of a shock from the bumpers. The linkage is guided by a bearing and controlled by a compensating spring. A rod transmits movement to a pivoting part which carries switches in the battery and alternator circuits. A pawl keeps the pivoting part in the open position (until re-set) to avoid the spring remaking the circuit.

Title: Engine deriving power from atmospheric heat - with air blown over evaporator and vapour delivered to power generator before cooling in reservoir
IPC: F01K25/10
Filed: 1975-10-01
Abstract: The engine incorporates a gear tooth pump which pumps a liquid refrigerant such as Freon from a reservoir and delivers it to a heat exchanger. A fan blows air over the fins of the heat exchanger and evaporates the refrigerant. The vapour flows to an engine where it expands and generates power. The liquid then passes to a reservoir where it can be cooled by means of circulating water or by using a commercial refrigerating compressor. By using sources of cold underground water the engine can supply power without using fuel and without polluting the atmosphere.
