Patent DE-2622101-A1 (DE)
Title: Electronic exterminator for flying insects - has light source or chemical substances to attract insects and HV to kill
Inventor: SCHUNK HELMUT
IPC: A01M1/22
Filed: 1976-05-18
Abstract: The electronic insect exterminator acts in conjunction with a light source to attract the insects in the centre of the appliance. The light source possesses a certain frequency and light intensity, and combines several colours of the spectrum. Non-toxic chemical substances, in liquid, powdered or solid form, can be used to attract the insects, or the insects can be attacted by a combination of the two. The insects are killed by means of a high voltage of between 500 and 5000V, the amount depending on the type of pest being destroyed. The killed insects are collected by means of a collector trough underneath the appliance, which can be easily removed and replaced.

Title: IC engine with dry lubrication system - has oil to pistons cooled to make dry lubrication possible
Inventor: KLAUE HERMANN DR ING
IPC: F01M9/00
Filed: 1977-05-23
Abstract: The engine has a cylinder block (1) with several cylinders in which pistons (4) reciprocate. A piston rod (5) from each piston runs to a spherical head (52) which seats in a recess in a swashplate (6). The swashplate is mounted on the output shaft (11). A hollow tube (28) attached to the underside of each piston surrounds the piston rod (5). The hollow tube (28) is sealed (30) to the bottom plate (31) of the cylinder. Oil from the drive housing (3) circulates through the hollow tube and a bore in the piston rod to cool the piston. The side of the piston or the side of the cylinder has a coating of graphite, molybdenum disulphide or ptfe to give dry lubrication. This reduces contamination of the exhaust and wear on the cylinders.

Patent DE-2724474-A1 (DE)
Title: Rotary and reciprocating IC engine - has rotary power piston driving rotary compressor stage
Inventor: SCHLAPP OTTO
IPC: F02B53/08
Filed: 1977-05-31
Abstract: The engine has a crankshaft (13) which is driven by a reciprocating piston (18) through a connecting rod. Two rotary pistons (3, 8) revolve eccentrically in two cylinders (4). They are connected by a common shaft (11). Fuel air mixture enters (2) the first rotary cylinder in which first stage compression takes place. The mixture then transfers to the reciprocating cylinder in which a second stage of compression takes place and a first stage of expansion occurs. The partly burnt gases pass into the second rotary cylinder in which a second stage of expansion takes place. The direct connection between the two rotary pistons simplifies construction and leaves the reciprocating piston to provide the useful output while the second rotary piston drives the first.

Title: Olefin! copolymer thermoplastic elastomer refrigerator sealant - contains ethylene! and propylene! copolymer opt. mixed with homopolymer or EVA copolymer
Inventor: WARTUSCH JOHANN DIPL CHEM
IPC: F25D23/08
Filed: 1977-08-03
Abstract: Sealing materials for refrigerators and freezers, partic. profiled seals at evaporator doors, contain a thermoplastic elastomer based on olefin copolymers, pref. C2G4/C3H6 copolymers. The C2H4/C3H6 copolymers can be mixed with homopolymers of C2H4 and/or C3H6, to improve rigidity or hardness without changing flexibility. A good flexibility and hardness adjustment can be achieved by adding C2H4/vinyl acetate copolymers to the C2H4/C3H6 copolymers. The olefin copolymers may also be mixed with polyurethanes, styrene-butadiene block copolymers or polyesters. The materials have even cold-flexibility over a wide temp. range, are physiologically inert, resist ageing, can be heat-sealed and do not cause damage of other materials in refrigerator.

Title: Telecommunications loudspeaker with bass resonator - has diaphragm with circular ridge having acoustic coupling holes in it linking front and rear
Inventor: MARTIN ERWIN DIPL ING
IPC: H04R1/22
