Title: Forming thin insulation barrier between two components - chemically linking component spacers with cast resin for e.g. cable clamp
Inventor: CZERNEK GEORG
IPC: H02G15/00
Filed: 1979-12-13
Abstract: The process eliminates voids or gas bubbles in the insulation giving points at which electrical breakdown can occur. To ensure an insulation wall of constant thickness between, e.g. an inner conducting core and an outer sheath or screen, spacers are inserted between the two components. The resulting volume is then cast with insulating resin. The spacers are made from, or coated with, material which reacts with the casting resin. When the latter begins to harden, and can itself maintain the required position of the components, the spacer material melts and fuses with the resin to give a homogeneous mass. The formation of voids and discontinuities in the region of the spacers is thus eliminated, or at least greatly reduced.

Title: Headrest for vehicle passenger seat - which is moved into position when seat is occupied and safety belt is fastened
Inventor: GMEINER GUENTER DIPL ING
IPC: B60R22/02
Filed: 1980-05-30
Abstract: In order to improve the driver's vision in the rearward direction the headrests (2) of unoccupied seats are automatically moved to a retracted position. The headrest is linked with a motor operated mechanism which raises it to the in use position when the seat is occupied. The command signal to the motor is given when the seat belt fitting (4) is put into use. Typically an electrical switch (7) is incorporated in the seat belt latch or buckle (6). The proposed arrangement eliminates the use of a pressure switch associated with the seat cushion. It is therefore possible to place packages on the seat without at the same time raising the headrest. Also sag in the seat due to frequent use does not cause an unwanted raising of the headrest.

Title: Roofing tile with snow-catching device
Inventor: ORBKE HELMUTH
IPC: E04D13/10
Filed: 1981-01-31
Abstract: The invention relates to a single-part roofing tile with attached snow-catching nose and a multi-part snow-catching device, the two systems being considerable more cost-effective than the conventional systems. The known catching devices comprise metal grids which are mounted on house roofs. The grids use up a large amount of material. Moreover, mounting carried out by specialist firms is very expensive. All the invention has to do is to provide a snow-catching device which is less expensive in terms of material usage and mounting. The low material usage and the extremely simple mounting of the system presented here make it possible to equip all pointed roofs with the new invention. The particular advantages of the invention lie in the simple design. There are two alternatives, as follows:   1) The roofing-tile manufacturers produce a purpose-made roofing tile with integrated snow-catching nose. This attached snow-catching nose can be designed such that a heightening or expanding element can be mounted on it in order to ensure optimum functioning. 2) The roofing-tile manufacturers provide the roofing tile with a hole, cross/angle slot or the like. Catching elements which have been supplied or can be bought are then inserted into these cutouts. This work can be carried out by the specialist when roofing the house or it can be carried out by the lay person at a later date. The above-described roofing tiles can be fitted in a row in the lower part of the house roof, but can also be distributed over the entire roof.

Title: Method and arrangement for monitoring pulse channels of neutron flux measurement
Inventor: RELIC MILAN DIPL ING
IPC: G01T3/00
Filed: 1981-08-17
Abstract: A method and an arrangement for monitoring a pulse channel for measuring low neutron flux by analysing the amplitude spectrum. For this purpose, the amplified pulses coming from the counting tube are discriminated in accordance with their amplitude and registered in two or more counters which are in each case allocated to a particular interval of the amplitude spectrum. The number of the pulses registered per unit time in the counters and the ratio of these counting rates between one another and/or to their sum provide an indication of the shape of the amplitude spectrum of the pulse channel. Deviations of the shape of the amplitude spectrum from the standard shape are an indication of errors in the relevant pulse channel. The arrangement for carrying out the method provides a monitoring unit (18) which transforms the signals with the aid of a stretcher (2) and an analog/digital converter (3) and forwards them to a microprocessor (5) for analysis. <IMAGE>
