Title: Room heating system with air compressor - uses Diesel engine driven by electric motor for generating hot air
Inventor: SCHMITZ RUDOLF WERNER
IPC: F24D12/00
Filed: 1976-10-05
Abstract: The compressor plant consists of a diesel engine driven by an electric motor. The diesel engine pistons compress air in cylinders and heat it in so doing. This hot air is used for heating the house. The diesel engine has oil in its sump for lubrication but no fuel is fed into this engine. The engine itself is cooled by its usual cooking system for example water cooling or air cooling. The air cooled diesel engine is considered the most efficiency engine for the heating purposes in its system. The heating system must have condensate pump for removing the water condensing from the compressed air into the pipe system connected to diesel engine.

Title: Nuclear reactor test pebble discrimination - by lesser graphite content after passing hollow pebbles through measuring reactor
Inventor: DAOUD HASSAN DIPL PHYS
IPC: G21C17/06
Filed: 1976-12-01
Abstract: Operational pebbles (fuel, graphite and absorber) from a nuclear reactor are passed through a measuring reactor where the neutron absorbing, neutron scattering and by neutron fissile features are determined. An analysis program calculates the compsn, and apparent discrepancies are used to distinguish graphite elements from fuel elements of the same graphite content but with a different degree of burn-up. Test pellets which have to be sorted out from the reactor core for certain tests after one pass-through are also passed through the measuring reactor. They have the same external configuration as the operational pellets but are hollow and weigh much less than the graphite pellets. The identification of pebbles below a certain graphite content makes it possible to use test elements, passed through the reactor core, for studies of the fluid dynamics of a pellet pile in a nuclear reactor.

Title: Ski brake with automatic action - also has spring catch actuated by skier to prevent slipping when walking
Inventor: KENTER HERBERT-PAUL
IPC: A63C7/10
Filed: 1977-01-18
Abstract: A ski (1) is fitted with a ski-brake (32) which is normally held clear of the snow by the catch (13).

If required the brake can be released by operating the catch (13) with the tip of the ski-stock (30). This feature allows the brake to be used to prevent slipping when walking on icy surfaces or when climbing steep slopes.

Title: External rotor electrical machine - has stator principally constructed of thermally stable synthetic materials
Inventor: WAGNER MARTIN
IPC: H02K5/173
Filed: 1977-03-23
Abstract: The production cost of a small external rotor machine (7) can be materially reduced by constructing the stator frame of synthetic material which is thermally stable. Such a structure can be made by pressure forming or injection moulding. Additional insulation, for example between core ends and windings, can be made out of discs of insulation material. By using such a fully synthetic resin moulded structure the ability of the machine to withstand electrical faults is improved. As there are no metal parts in the frame an electrical breakdown, for example between windings and core, is not propagated to other parts of the machine. The bearing locations for the external rotor are also formed in the synthetic material during the casting stage.

Title: Flash butt welding of workpieces - where electronic comparator circuit keeps electric power at desired working point
Inventor: RUGE JUERGEN PROF DR ING
IPC: B23K11/24
Filed: 1977-06-10
Abstract: The process is stabilised while the workpieces are moving together at variable speed along a fixed path/time curve, by measuring an actual value (Ia) representing the electric power or the effective electric current. Value (Ia) is compared with at least two preadjustable reference values (I1, I2) and, if a critical value is reached, the current is automatically altered. The pref. welding machiens include meter feeding signal (Ia) into an electronic comparator using a trigger circuit fed with values (I1, I2); and the comparator actuates an ignitron supplying the machine with two power stages. The occurrence of short circuits is eliminated; and there is virtually no delay in controlling the process even when using a low idling voltage.

Title: Replenishing molten baths, esp. in soldering electronic components - where replenishing material is melted before entering bath
Inventor: STANGE BERND
IPC: B23K1/08
Filed: 1977-11-21
Abstract: The substance being used for replenishment, e.g. a rod (a) is pref. fed dropwise and by gravity into the bath, esp. using automatic replenishment controlled by monitoring the height of the molten bath. Pref. a rod(a) is located in a tube mounted above the molten bath and held in that tube by a heater located at the bottom end of the tube.
