Title: Engine oil reconditioner - has filter and evaporator plate across which oil cascades below heater, vaporized contaminants exhaust through valve
Inventor: PRIEST GLEN R
IPC: F16N39/00
Filed: 1975-09-12
Abstract: An oil reconditioner includes a closed casing with a main lower body portion and a removable top, and oil enters at the bottom and passes up through an annular fibrous filter mounted in the lower portion around a central oil outlet pipe also extending through the bottom, the oil emerging through a perforate plate at the top of the filter and then flowing radially outwards between this plate and the underside of an evaporator plate having capillary flow passages extending axially therethrough adjacent its rim, these passages being of a size to cause de-emulsification and being arranged to deliver the oil and any fluid contaminants onto the rim of the concave upper surface of the evaporator plate which has concentric tiers over which the oil and contaminants cascade as they flow to the outlet pipe which extends centrally through the evaporator plate, a heater being mounted in the top of the casing to encourage vaporisation of the contaminants as they pass across the evaporator plate, the vapours being free to escape through a valve in the top of the casing, this valve closing automatically in response to undue liquid level in the casing. Particularly for reconditioning lubricating oil of automobile or aircraft engines, the valve then preventing discharge of oil through the vapour outlet when the casing tilts.

Inventor: BEST HEINZ ING GRAD
IPC: G21C17/01
Filed: 1975-10-23
Abstract: A handling device for inspection equipment, such as ultrasonic detectors, inside a rotationally symmetrical pressure vessel comprises a rotational bearing at the centre of the vessel bottom and a support tube or similar vertical member which rest in the bearing and can revolve about the vertical axis of the vessel. The support tube has >=1 arm mounted on it so that they can pivot about a horizontal axis on the tube, their face end(s) carrying inspection equipment which sweeps the inner face of the vessel. The arms are movable axially (vertically) inside the vessel. Pref. the inspection head can pivot about the longitudinal axis of the arm. Used for any reactor pressure vessel which is rotationally symmetrical, esp. for a water reactor, either on land or marine. The inspection assembly can be introduced from the top through the restricted central passage of the annular steam generator, after this has been lifted out of the pressure vessel into the change tank temporarily mounted at the top. The assembly is adapted for both the cylindrical wall and the spherical bottom dome. It can be withdrawn when only power supplies are available, due to mechanical and electrical faults.

Title: Car heater linked to coolant circulation - has separate circuit heat exchanger to prevent air locks in engine head
Inventor: LAMM HEINZ
IPC: B60H1/02
Filed: 1975-11-27
Abstract: The water cooled engine has a closed circuit water system (2) and a separate circuit for the interior heater. The second circuit has a heat exchanger (15) near the cylinder heat to transfer heat between the two systems, without transfer of air locks etc. The second circuit is powered by a pump (13) and has a second heat exchanger through which the hot exhaust gases are passed. The second circuit has additional loop (30) through the engine block and is filled with either coolant or hydraulic fluid. The system provides a fast heating time for the engine, with heat being taken from the exhaust lines, without danger of air locks overheating the blocks. The second heat exchanger, near the block, acts as a top up level for the second system.

Title: Hub drive mounting for tank track - with asymmetric elastic bearings to chassis to accommodate track vibration
Inventor: SEIT HORST
IPC: F16F15/08
Filed: 1975-12-06
Abstract: The final drive of the tank track has an epicyclic reduction gearing (3) as a hub drive of the drive wheel (12) over which the track is looped. The hub drive is fitted to flanges (6, 10) spaced on the inside and outside of the hole (5) through the tank chassis, by special elastic elements to dampen vibration. As the track is pulled over the teeth of the drive wheel it is subjected to tensile vibrations which can damage the transmission and lead to excessive vibration inside the vehicle. The elastic pads serve to dampen these vibrations, with the elasticity chosen to give in the direction of the tensile forces, but to strengthen the drive in the other directions. The coupling to rest of the transmission is by universal joints on a drive shaft (4).
Patent DE-2555133-A1 (DE)
Title: Linear motor for transport systems with locally defined speed - has pole pitch of stationary primary winding varied along its length to define speed of travelling secondary
Inventor: ROSENBERG HEINZ DIPL ING
IPC: H02K41/03
Filed: 1975-12-08
Abstract: The linear motor is used in conveyor systems or local light transport services where the speed at any point along the route is preset. The pole pitch of the stationary primary winding is varied along at least one part of its length. This automatically adjusts the speed of the travelling secondary without the need of a further control system. The method can be extended to include supplying different parts of the primary with different frequencies, suitable overlapping being provided between their zones. A variable element may be introduced if needed by providing for frequency control of one or more of the independently supplied sections of the winding.

IPC: G01D5/20
Filed: 1976-01-30
Abstract: A transmitter element for a mechanical-electrical converter for distance measurement has a core of magnetically conducting material and another coil movable relative to it. It produces large inductive changes for very small distance changes in order to provide more reliable and less troublesome distance evaluation. The coil (12) has an associated conducting piece (14) of magnetically conducting material which, in one end location of the transmitter, almost completely closes the magnetic circuit. The core (10) is E-shaped and the coil slides over the central leg (11). The circular conducting piece bridges the air gaps between the arms of the core in one end position.
Patent DE-2605227-A1 (DE)
Title: Ring cage for planet wheel location - is welded together by axial studs to restrict heat application
Inventor: LEBER FRITZ ING GRAD
IPC: F16H57/08
Filed: 1976-02-11
Abstract: A location ring for planet wheels of an epicyclic gear is made from two flat rings which are joined together by three equally spaced axial studs. The planet wheel location is the space between the axial studs, and they do not require any further machining after welding the two location rings together. The length of the axial studs is half the axial distance between the two ring plates. Thus when the studs are welded together in order to join the plates, the heat application is restricted to the studs. In this way the location plates remain free from heat distortion and therefore do not require further treatment.

Title: Bistable tactile pin for forming braille symbols - has induction coil with adjustable magnetic core giving fast response time
Inventor: BOLDT WERNER PROF DR
IPC: G09B21/00
Filed: 1976-03-03
Abstract: The bistable tactile pin with mechanical interlock is for representation of braille symbols and employs an electromagnetically controlled vertical tilting or flexing effect. The bistable condition is achieved by the tilting of a mechanical element. The condition may also be achieved by tilting of two mechanical elements, flexing of a leaf spring or a combination of these motions. The motion may be produced by one or more moving magnet cores in the force field of an induction coil (solenoid), or by an impolarisable fixed magnet in this field.

Title: Adjustable multi-stroke engine with fuel injection - injects fuel only at every other or third fuel suction stroke
Inventor: KUHN PETER R DR ING
IPC: F02B75/02
Filed: 1977-01-26
Abstract: The adjustable four stroke IC engine has fuel injection system and regulator. The engine mode of operation is changed to ensure low fuel consumption on idling and in lower loading range. Below a certain min. loading fuel is injected only at every other suction stroke so that engine operates as an eight stroke cycle engine. The fuel can be injected also at every third suction stroke. The engine exhaust becomes hence less toxic and this assists in preventing air pollution.
