Patent DE-2709602-A1 (DE)
Title: Transportation vessel for spent nuclear fuel - has heat shield protecting contents from external fire by bulging bimetal plate
Inventor: GUY RONALD
IPC: G21F5/10
Filed: 1977-03-03
Abstract: The container comprises a bimetal plate fitted to the external surface of the container. This bimetal plate is composed of two metal plates possessing different coeffts. of thermal expansion; the outer plate has a larger coefft. of expansion than the inner plate and both the plates are firmly connected together at their edges and fixed to the outer face of the container. The surface of the bimetal plate facing inwards towards the container and the external surface of the container itself are finished to a high polish and are in intimate thermally conducting contact. There may also be a further metal plate between the bimetal plate and the outer face of the container; this plate has a high polish on the side facing away from the container. If the container is subjected to an external fire, the outer bimetal plate immediately buckles outwards and creates a void (virtually a vacuum) between it and the inner plate or surface of the container. Since the two surfaces of this void are highly polished, very little radiation of heat across the void takes place and the contents of the container are largely protected from the external heat.

Title: Removal of moisture from underground floors - using electro-potential system with anode made from conducting plaster or coating as layer on inside of wall
Inventor: MORARU DINU STEFAN DR ING
IPC: E04B1/70
Filed: 1977-05-20
Abstract: Subterranean floors in buildings are kept dry by an electro-drainage technique. The plus electrode for this is formed as a conducting plaster or paint on the inner side of the wall. The minus electrode is on the outside, mounted as an earth at a distance from the wall in the ground. To seal and draw of any water rising rising by capillary action horizontal holes are bored near the base of the wall through it. Into these the conducting plaster or mortar is injected to act as electrodes, having good electrical connection with the conducting plaster layer. The two types of electrodes are in such number and construction that the current density on the earth surface facing the wall is approx -jp =10-4 A/cm2 while that of the wall - ji =0.25 x 10-4 x t-1 A/cm2 where t is the thickness of the wall being protected.

Title: Carburettor for IC engine - has pneumatic cold start components limiting opening of main throttle during starting
Inventor: CHENET JACQUES
IPC: F02M3/06
Filed: 1977-07-28
Abstract: The carburettor has a main throttle (5) downstream of the fuel inlet (3) and an auxiliary throttle (115) upstream of it. The auxiliary throttle is moved by a bimetallic coil (120) and a membrane (128) acted on by the suction in the manifold. A cold start channel (7) opens near the main throttle. The movement of the main throttle is limited by the plunger (70) of a solenoid (71) which is energised by the ignition circuit and de-energised by a pneumatic switch (74). This limits the movement during starting and frees it when the engine reaches normal speed. A rod (57) moved by a pneumatic actuator (20) adjusts the main throttle to keep the engine speed constant. The actuator is operated by the suction pressure and atmospheric pressure.

Title: Reinforced concrete structure continuous crack sealing - is painted on with organic silicon compound following compressed boiling water jet spraying
Inventor: LUTHE WOLFGANG
IPC: E04G23/02
Filed: 1977-09-21
Abstract: The process for sealing continuous fissures in reinforced concrete structures, with initially sloping surface, involves application of a substance which can be painted on. Cleaning is effected by spraying water under high pressure, at above >100 degrees C, vertically in a short jet, the jet being pushed vertically across the surface and fissure parallel to the surface. Adjoining flank, impregnation is carried out by flooding with a dissolved organic silicon cpd. The substance formed by fluid mixt. fo this cpd. with a long-chain agent combining with the silicon components is then painted on. The covers wider gaps, enabling leaf cracks to be effectively sealed.
Patent DE-2745956-A1 (DE)
Title: Laying tunnel or pipe through earth mass - involves first leading draw units through then exerting tractive force on them
IPC: E21D9/00
Filed: 1977-10-12
Abstract: In laying a man-made construction, such as a conduit or tunnel, through a mass of earth, the elongated hollow unit is set in place with open front end against a bank, and gradually moved forward while earth is removed from inside. For forward movement a number of traction units (7) are led from this slide through the earth, until they reach the other side of the mass of earth (1). The unit (8) is then connected to them, and tractive force is exerted on them on the other side. They can be in the form of rods directly pressed or rammed through the earth. This prevents any deviations of the unit centre line away from the intended correct alignment.

Title: Servo operated coupling for combine harvester - has lever mechanism to reduce pedal force necessary for clutch disengagement
Inventor: DAMNJANOVIC MILIVOJ
IPC: A01D69/08

Title: Pressure cylinder for machine tool clamp - has non-return valves which are held slightly off seats for low pressure clamping
Inventor: BRANGS ECKHARD DR ING
IPC: B23B31/30
Filed: 1978-12-06
Abstract: A pressure cylinder is used to actuate the tool clamp of a machine tool and rotates with the tool. The double acting piston is controlled by a pair of spring loaded non-return valves which can be lifted off their seats by pistons. The springs must be sufficiently strong to close the valve against the effect of centrifugal force in the event of a supply pressure failure. But when only a light clamping pressure is needed it may be insufficient to open the valves. This difficulty is overcome by using a second piston which holds two balls very slightly off their seats.
