Patent DE-2545584-A1 (DE)
Title: IC engine with two different dia. and speed rotary pistons - rotating in same direction and in constant mutual sealing contact
Inventor: HEUSSER ALFRED W
IPC: F01C1/34
Filed: 1975-10-11
Abstract: The combustion engine has a multi-edged piston (1) rotating in a cylindrical housing (2). A smaller, subsidiary two-edged piston (9) rotates in the same direction at a different speed in a subsidiary cylindrical housing (3), communicative with and parallel with the main housing (2). The arrangement is such that, at all times, a sealing edge of one piston is in sealing engagement with the circumference of the other piston, whilst the remaining edges engage the cylinder walls, thus producing chambers of cyclically varying volumes as required for a four-stroke process. Inlet and exhaust parts are arranged in the main housing wall and separated by a sealing strip engaging the main piston. Ignition means (5) are arranged in the subsidiary housing wall.

Title: IC engine supercharge temp. control - compressor output is heated at low speed and cooled at high speed
Inventor: STANKEWITSCH LEO DR ING
IPC: F01P3/20
Filed: 1975-11-03
Abstract: Engine (1, 2) has an exhaust gas (4) driven compressor (3). The compressor output enters a first heat exchanger (5). The heat exchanger receives its heat from the engine cooling system which contains a three way valve (8) and a thermostat (9) to keep the cooling system at a constant temperature when running. The compressor output next enters a second heat exchanger having a lower temperature then the engine water cooling circuit. The cooling effect of the second heat exchanger is suspended during slow running and low loads and regulated in dependence with the engine air intake temperature.
Patent DE-2557391-A1 (DE)
Title: Endplate fastening for small electric motor - has deformable metal strip attached to stator and received in notched location in endplate
Inventor: ROMBERG LOTHAR
IPC: H02K5/15
Filed: 1975-12-19
Abstract: In small machines studs or bolts for retaining the endplate may be replaced by deformable metal strips (5). These are permanently attached to the stator (1) where, by spot welding at each end, they may also serve to clamp the laminations. The ends (12) of the strip are initially bent outwards (18) to permit placing the endplate in position. The assembly sequence is then to bend the end straight, and subsequently to bend (19) the outer end over the endplate (3). The endplate has slots or notches (13) into which the end of the strip fits to give circumferential positioning. The notch base is also above that of the general diameter of the endplate so that by bending the strip over the end of the notch (20) an axial clamping force is exerted.

Title: Brake system for automatically closing fire protection gates - is actuated by lever or inclined plane for ensuring min. effective force to reduce impact and risk to escaping persons
Inventor: KAUFFMANN HANS DIPL ING
IPC: E05F5/02
Filed: 1976-03-06
Abstract: The brake system is used for fire protection gate closed by potential energy after a holding mechanism has been released. The closing energy is generated by counter-weights, springs, compressed air storage arrangements or by inclined travelling path of the gate. The gates are accelerated during movement and very high impact forces are generated at the end of travel. The brake arrangement reduces impact forces and the risk that persons of objects are crushed between the closing gates. The brake has a cylinder actuated by a roller lever or by inclined skid. The energy of gate closing can be also absorbed by a friction system. This brake arrangement can be used for sliding, rotating, folding, lifting, lowering and tilting gates.

Title: Central heating system controlled by outside conditions - uses monitoring and comparison system to regulate fuel supply
Inventor: KNOLL ALIIS DIPL ING DR
IPC: F24D19/10
Filed: 1976-07-09
Abstract: A central heating system operated to adapt to the time of day and/or the time of year, alters the predetermined time intervals. After a second set of predetermined time intervals, the heating is cut off and if a predetermined support temperature differs from the normal temperature the ambient temperature is controlled by comparison. During the second time intervals, the heating is reversed so that the normal temperature is reached as quickly as possible. In cold external conditions, the support temperature is raised, and is controlled from two fixed points. For outside temperatures which require the maximum heating up during the first time intervals, the support temperature is adjusted to the estimated normal temperature.

Patent DE-2700081-A1 (DE)
Inventor: LENGENFELDER WALTER ING GRAD
IPC: H01C1/16
Filed: 1977-01-04
Abstract: The test resistor device consists of a multiplicity of fixed resistors (R1-Rn) which can be connected and disconnected in parallel. The connection and disconnection of the fixed resistors is in each case effected at the zero crossing of the power system voltage by means of controllable semiconductor switches (Th1-Thn). The semiconductor switches are controlled via a binary counter (10), clocked by a power-system-frequency pulse sequence, with a number of counting stages (ZS1-Zsn) corresponding to the number of fixed resistors. This makes it possible to generate a sinusoidal fault current, which varies continuously with a corresponding number of fixed resistors, for testing fault current and fault voltage protection circuits. <IMAGE>

Title: Underground mineral salt mining system - makes outward and return cuts by reversing machine, then repeats cut at lower levels
Inventor: GROSSMANN RUDOLF
IPC: E21C41/20
Filed: 1977-02-12
Abstract: A method of mining mineral salts uses a mining machine (18) and a system of belt conveyors (3) in which the cut material is deposited onto a vibratory discharge device (11) which allows the material to fall into a vertical shaft to a take off conveyor at a lower level. The other end of the conveyor is attached to a tensioning unit (20) which allows that end to travel as the mining machine travels. After making a cut (I) parallel to the belt, the machine is swung around to make a parallel return cut (II). The machine is then swung round to make another parallel cut (III) in the same direction of the first cut (I). After a series of parallel cuts, another series is cut at a lower level. This is repeated for successively shorter lengths of travel so that a sloping chamber is made.
