Title: Furniture hinge with four bar linkage arrangement - has ratchet mechanism in hinge to ensure opening and closing
Inventor: KRAUTTER KURT
IPC: E05D11/10
Filed: 1977-03-12
Abstract: The cupboard hinge has parts on the door and on the body, connected with internal and external hinge levers. The pivoted hinge system forms a four bar linkage lifting door or flap before swinging open. The door or flap is kept open by a ratchet mechanism. The hinge pivot on the furniture body side of the hinge lever is able to slide in the fixed hinge part. This sliding component rests under the effect of a ratchet spring against an arm connected to the second hinge lever. The mechanism is arranged so that in the closed position of the hinge, the arm and the sliding hinge axis are connected by ratchet effect.

Title: IC engine with auxiliary combustion chamber - admits rich mixt. to main chamber and air only to auxiliary chamber
Inventor: RENGER UDO DIPL ING
IPC: F02B19/10
Filed: 1977-06-29
Abstract: The engine has a piston (2) reciprocating in a cylinder (1), and a main combustion space (5) formed between the piston and the cylinder head (4). There is an auxiliary combustion space (7) formed in a recess in the cylinder head. An inlet valve (10) admits a rich mixture into the main combustion space (5).

The thyristor anode can be connected to the generator positive pole via a first parallel circuit comprising a resistance and a capacitor, parallel to the generator output terminals. The cathode is connected to the thyristor gate via a second parallel circuit similar to the first. The primer unit is connected between the cathode and the generator negative pole, and has a resistance in parallel.
Patent DE-2741294-A1 (DE)
Title: Waffle moulding machine - with roll faces sealed by block with curved scraper recesses
IPC: A21C15/00
Filed: 1977-09-14
Abstract: A waffle moulding machine with contrarotating rolls prevents the leakage of the sugary mass at the face ends of the rolls by spring-loaded sealing blocks with scraper recesses. These recesses are curved and extend from outside the roll periphery to a point above the roll gap. This prevents any leaking mass from contaminating the conveyor for the waffle discharge or from accumulating at other undesirable spots. it avoids the use of lip seals which have a short life because of the abrasive nature of the mass. All parts are easily detachable for cleaning.

Title: Removing internal radioactively contaminated layers from pipes etc. - by grinding paste mixt. forced through pipe
Inventor: KAEMMERLING MICHAEL
IPC: G21F9/28
Filed: 1977-10-18
Abstract: A method of removing radioactive contaminated surface layers from the inside of pipes and similar structure consists of forcing a grindingb paste through the pipe. Pref. the grinding paste is composed of an abrasive substance, a chemically aggressive or inert liquid, possibly also a carrier material or vehicle for the abrasive substance, and also metal particles of 0.5-5mm dia. which are chemically inert to the grinding liq. Used for removing the contaminated material from the inside of pipes, valves, heat exchangers and the like before disposal of the components. The method enables the amt. of decontaminated material to be kept to a min. since the bulk of material remaining after the surface layer has been removed is non-active. The method does not require the use of manipulators or other remote operating devices.

Title: Hollow reinforced concrete beam with ceiling part - has reinforced ribs with projecting loops holding grid for ceiling concrete
Inventor: LUBIAN ENZO
IPC: B28B23/18
Filed: 1978-03-09
Abstract: Hollow beams of reinforced concrete has reinforced bottom ribs and base which forms the sealing under the completed slab assembled from these beams. This beam can have three vertical load bearing ribs connected subsequently with a reinforced base forming the ceiling for the room below. The reinforcing arrangement is placed on to deep channels of the formwork made from folded sheet metal. The concrete is poured into these channels so that the loops of the brackets project beyond the bottom of the load carrying ribs of the beam. A flat grid is anchored on these loops. The latter is embedded in a mould into a concrete layer to form a base which also consists of reinforced concrete. This concrete forms the ceiling and contributes to load carrying capacity.

Title: Determn. of capacitance when winding aluminium capacitors - by using ionised air as temporary measuring electrolyte
Inventor: EPPLE RICHARD DIPL PHYS DR
IPC: H01G9/00
Filed: 1978-03-15
Abstract: An oxidised Al foil (a) is sepd. by a paper foil (b) from an Al foil (c), and the assembly (abc) is wound onto a former. During winding, an ionised gas is fed into the dry winding to function as the electrolyte so the capacitance of the winding can be measured; and winding is stopped when the capacitance reaches a desired value. The ionised gas is pref. produced by a discharge appts. located near the point where the foils (abc) are wound onto the former; and electric contacts are made with foils (a, c) outside the wound coiled for measuring the capacitance. Contact (a) is made by removing the oxide from the start of the foil (a), esp. by etching. Measurement can be made in the dry state, i.e. before using the liq. electrolyte so windings which are too short or too long are eliminated, and costs reduced by saving in foil.

Title: Solar heat collector - with absorber tubes in funnel pattern of flattened hexagonal cross=section for even heat distribution
Inventor: GUETLHUBER FRIEDRICH
IPC: F24S10/70
Filed: 1978-07-28
Abstract: Bundle of absorber tubes are arranged inside a casing with an opening to face the incident solar radiation. This can be mounted on a tower or on level ground.
