Patent DE-2910957-A1 (DE)
Title: Electric temp. sensor with low time constant - uses naked resistance wire whose dimensions provide low resistance compared with that of measured medium
Inventor: KROEBEL WERNER PROF DR
IPC: G01K1/18
Filed: 1979-03-21
Abstract: In the temp. sensor with an extremely low time constant a bare resistance wire is directly inserted into the medium to be measured. It is of such reduced length and of such thickness that its electric resistance is sufficiently low - compared with that of the measured medium - while being of sufficient mechanical stability. Its thermal capacity is minimised by a sufficiently small cross section. The wire consists, e.g. of platinum, or of a special material with high specific resistance such as titanium. It pref. has a low pressure coefficient, while having simultaneously a sufficient electric temp. coefficient. This wire is connected to the input of a transformer which transforms low ohmic thermometer resistance without noise to a high resistance, sufficient for further signal amplification. The transformer input lies directly in an a.c. bridge diagonal.

Title: Spent nuclear fuel element storage basin - with stainless steel granules filling voids between fuel rods
Inventor: VOX ANTON I
IPC: G21F9/36
Filed: 1979-03-22
Abstract: Spent radioactive fuel elements are stored prior to transport to a processing plant under water in a container. The space left in the container between the fuel rods is filled up by pouring in granular or powdery material with good thermal conductivity such as alloy steel. This greatly improves the heat dissipation from fuel elements extracted from a nuclear power station and shortens the time required for storage in the depository basin before transport. The advantage of dry transport are retained.

Patent DE-2930009-A1 (DE)
Inventor: FAUSCH WERNER
IPC: H01H50/02
Filed: 1979-07-24
Abstract: The electromagnetic relay serves especially for use with printed-circuit boards and has a seal (25), consisting of elastic material, between the lateral surfaces of the base (11) and the housing (19). In consequence, a virtually liquid-tight relay is produced using simple means, which relay can be soldered in the solder bath with a printed-circuit board without any risk of vapours or liquid from the cleaning baths penetrating into the relay. In contrast to known hermetically sealed relays, the relay according to the invention is considerably cheaper to manufacture. <IMAGE>

Title: Automated sealing of battery plate borders with extruded foam - opt. using expanded polyethylene shaped by external profile wheels
Inventor: WILLIS STUART
IPC: H01M2/14
Filed: 1979-08-09
Abstract: The borders of sandwich structure battery plates are sealed by passing a series of plates automatically past equipment which extrudes and shapes a foamed plastic material to enclose the borders of the sides and, if necessary, the base of the plates. Process is more efficient than conventional manual manipulation of plates to fit prefabricated seal profiles. It is applicable to plates with covers of e.g. polyester materials which cannot receive profiles which require ultrasonic welding.

Title: Eccentric two-edged rotary piston engine - has combustion chamber ports diametrically opposed to inlet and outlet ports for piston cooling
Inventor: LOTHAR JAEGER PRODUKTIONEN
IPC: F02B55/04
Filed: 1979-10-23
Abstract: The rotary piston engine comprises a two-edged piston (1) eccentrically rotating in a cylindrical housing mantle (6) with inlet (4) and outlet (5) ports arranged diametrically opposed to the ports (7) of a combustion chamber (5).

Title: Turbine and generator unit - has closed circuit operating medium with gear coupling between turbine and rotor to give integral construction
Inventor: BAYER FRANZ XAVER
IPC: F01K11/04
Filed: 1979-10-30
Abstract: The thermal power of the turbine and generator unit is provided by a coal burning furnace, typically employing a chain gate (1,2) passing beneath a number of turbo-generator units. Heat from the grate evaporates the operating medium (10), typically liquid sodium, and causes the resulting vapour to expand through a turbine runner (5) with contra-rotating intermediate blades fixed to the electrical rotor assembly (3). At the exit from the turbine a compressor pump (14) returns the medium, in liquid form, to the boiler. An epicyclic gear system (18-21) couples turbine and electrical rotor. The ratio is chosen to give the required synchronous speed from the optimum turbine speed. The rotor poles (4) are mounted directly upon the rotor structure (3). The stator (7) is contained in the unit outer casing (6).

Title: Optical fuse of stand=off type - has receiver with separate analogue storage units for scatter and reflected light
Inventor: PLATZ WILLI DIPL PHYS DR RER N
IPC: F42C13/02
Filed: 1979-12-08
Abstract: The optical stand-off fuse comprises an emitter operating on the pulse system and a receiver sensor, each with a lens, and offset from each other, so that reflection of a point of light onto the receiver surface generates a firing signal. The receiver (11) has two channels (I,II), the first of which receives the scatter light immediately before the emission impulse into a first analogue storage unit (12). The second receives in synchronism with the impulse the sum of the reflected and scatter light into a second such unit (13). The outputs of both units are connected to a subtractor (14), which is followed by a detector (16) generating an initiation signal when light intensity is at the maximum.

Title: Device for controlling the fuel feed on internal combustion engines
Inventor: IKEURA KENJI
IPC: F02D41/12
Filed: 1981-01-30
Abstract: The control device determines the blocking or restoration of the fuel feed to an internal combustion engine in a motor vehicle, according to operating conditions. At the same time according to the invention a speed default value (NR), at which the feed is restored, is so modified (NR') as a function of the speed deceleration rate, for example in engine braking, that considerable fuel is saved. On the other hand the default value remains unchanged as determined on the basis of the cooling water temperature when the engine speed is reduced in idling or in rapid engine braking. <IMAGE>
