Title: Slimming device with exercise ring - has rotating mass indexing counter upon each rotation
Inventor: MUELLER-DEINHARDT FRIEDHELM
IPC: A63B22/18
Filed: 1979-08-29
Abstract: The slimming device comprises a hollow ring, which has handgrips at two diametrically opposed points and containing a mass which rotates around the inside of the ring when this is moved rhythmically. At one point intermediate the two handgrips, a counter mechanism is attached to the ring, so that it is indexed by the passage of the mass, to record the number of revolutions of the latter. The read-out window for the digit drums of the counter mechanism lie in a plane which is parallel to the plane of the ring. The ring is made of plastics material with the mass comprising a steel or lead cylinder, the counter mechanism being indexed via a pivoted finger projecting into the inside space of the ring. Two spaced sensors can be positioned on the ring and producing electrical signals supplied to the counter mechanism via an electrical comparator.

Title: Metal strip-securing equipment during welding - has core in two sliding parts coupled by rams and springs
Inventor: KRIEGER FRIEDRICH
IPC: B23K37/04
Filed: 1979-10-05
Abstract: The equipment comprises a thrust bearing, an abutment and a core, and secures sheet metal strips, bent at right angles along their lengthwise axes, while they are welded together to form a hollow body housing nuclear fuel elements. The core is in two sliding parts, coupled together by rams, spring components and screws adjusting the ram stroke.

Title: Lignocellulose contg. fibres prodn. - from chips disintegrated mechanically after preheating in two pressure stages connected to inlet and outlet of disintegrator
Inventor: CEDERQUIST KARL NICOLAUS
IPC: D21B1/14
Filed: 1979-10-12
Abstract: Lignocellulose material contg. fibres are produced from chips preheated by steam to 80-100 degrees C and disintegrated in a steam atmos. at a temp. of from 100-200 degrees C. Preheating is effected in two pressure stages, the frist one of which into which the chips are fed being interconnected with the disintegrator by a by-pass and being subjected to a lower pressure than the second stage. Latter is connected to the inlet side of the disintegrator and maintained at constant pressure and temp. Feeding of chips between the two stages is effected such that leakage of steam from the second stage into the first stage is prevented. Interconnection of stages with the disintegrator leads to recovery of steam and saving of electrical input energy.

Title: Back-up domestic electric water heating system - is used for solid fuel boiler, e.g. to supplement water heating via solar collector
Inventor: DEPPE HANS
IPC: F24H3/08
Filed: 1979-10-24
Abstract: The electric water heating system is used in the summer months to heat the water in a solid fuel boiler, e.g. when full central heating is not required. A manual switch (30) is operated to disconnect the automatic solid fuel feed (20) and connect the electric heating (32). The electric heating system uses at least one heating tube (25) which heats the boiler water, with the switching contacts determining the heating mode connected to a throttle valve in the smoke pipe causing it to close when the electrical heating (32) is switched into operation. Pref. a single thermostat (14) contacts both heating modes and allows the electro heating (32) to be used to supplement heating of the water via a solar collector.

Patent DE-2945727-A1 (DE)
Inventor: WEINHANDL FRANZ
IPC: F04B25/02
Filed: 1979-11-13
Abstract: The air compressor has a cylinder (1) which has arranged therein in a movable manner a stepped piston (4) which performs work of compression in both directions of travel. Associated with each compression stage there is at least one inlet and one outlet valve (34, 36 and 35, 37, respectively), an outlet port of a lower pressure stage being connected to an inlet port of a higher pressure stage. All the valves (34-37) are arranged at the head side of the compressor, in the region of the cylinder head (13; 30). The compressor consists of few individual components, and the valves are easily accessible for maintenance, which is important for fitting in a lorry diesel engine, as space in the engine compartment is very constricted. <IMAGE>

Title: Magnetic polarisation surge generator for ignition distributor - has ferromagnetic wire surrounded by pick-up coil and with long ends extending to avoid affecting magnetic reversal
Inventor: ESPER FRIEDRICH DR
IPC: F02P7/067
Filed: 1980-02-16
Abstract: Electrical signals are generated by magnetic reversal of a mechanically pre-treated ferromagnetic wire surrounded by at least one pick-up coil, the arrangement being suitable for an ignition distributor system. Both ends of the wire (8), e.g. Wiegand wire, project so far out of the pick-up coil (9) that they do not affect the reversing of the magnetization.

Patent DE-3014301-A1 (DE)
Inventor: UHLMANN GEORG
IPC: A61D1/08
Filed: 1980-04-15
Abstract: An apparatus is provided for livestock obstetrics. The apparatus bears against the body of the dam, a leg sling is placed on the offspring, and two slides can progressively be moved along a rod to tension the leg sling. To move the slides, a tensioning lever is hinged to one slide, and an intermediate lever is hinged at a different location to the one slide and is also hinged to the other slide. The intermediate lever is in two parts normally held together by spring tension, but if an excess load is applied by the tensioning lever the spring tension is overcome and the parts separate, whereby maximum permissible tension between dam and offspring is not exceeded. To completely release the pull on the offspring, the tensioning lever can be moved to release both slides.

Title: Compact gyroscopic compass with magnetic damping - has rotor axis inclination sensor consisting of body displaced on rotor axis exerting torque
Inventor: KARNICK HARTMUT
IPC: G01C19/38
Filed: 1980-04-29
Abstract: The gyroscope frame is mounted so as to swivel w.r.t. the compass housing. A rotor swivels in all directions about a central point. A sensor detects the inclination of its axis. The sensor controls torques which permit and damp precession of the rotor axis in the meridian plane. The compass eliminates the undesired drift torques associated with similar devices and is more economical and compact. The sensor consists of a body (46) mounted on the gyroscope rotor (30) and moving in the rotor axial direction. The body occupies a position for which the common centre of mass of itself and the rotor coincides with the central point. When the rotor axis tilts, the body is displaced and exerts a torque causing meridian plane precession by virtue of its wt. A magnet system (64) exerts damping torques on the body.
