Patent DE-3707769-A1 (DE)
Title: Installation for transmitting solar energy to liquid present in a vessel
Inventor: HEINZEL VOLKER DR
IPC: F24J2/44
Filed: 1987-03-11
Abstract: An installation for transmitting solar energy to liquid present in a vessel, having a closed circuit for generating steam by direct evaporation of a heat transfer medium in a solar collector as heat source, circulation of the heat transfer medium in the circuit by natural convection, a heat sink connected into the circuit or a heat exchanger for transmitting the heat to the liquid in the vessel, which is arranged geodetically higher than the heat source, and also having pipelines connecting heat source and heat sink from outlet and inlet in each case to one another. What is novel in the present invention is that the heat sink is constructed as a steam condenser 5 which can be immersed from above into the liquid 9 or into the vessel 7 and that steam supply pipe and condensate discharge pipe of the condenser 5 are guided upwards over the vessel rim 8 against the force of gravity. This function is obtained by the installation of two siphons 12 and 13 which connect the inner space 17 of the condenser to the air volume 20 of an air collector 21, from which the resultant condensate is returned again to the solar collector 1. The present invention enables the use of a solar-heated heat source which can be immersed into conventional vessels directly from above without the need for further energy from external sources. <IMAGE>

Title: Method for producing a semiconductor component
Inventor: GANTIOLER JOSEF DIPL ING
IPC: H01L21/60
Filed: 1987-07-24
Abstract: In order to produce a semiconductor component having an insulating layer which thickens towards the rim of the semiconductor body, the planar zones are firstly produced in the semiconductor body. The next step is to apply an insulating layer which covers the entire surface and has a thickness such as is provided at the rim of the semiconductor body. The insulating layer is thereafter etched thinner at least over the planar zones in such a way as to produce an obliquely falling course between the two regions of different thickness. Finally, a contact hole (via) is etched in the region of the planar zones and a contact layer is applied.

Patent DE-3809893-A1 (DE)
Inventor: BUSSKAMP WALTER DIPL ING
IPC: F24D3/00
Filed: 1988-03-24
Abstract: An arrangement for remote transfer of heat to a hot-water system comprises at least two heat exchangers (10, 11) of similar size, shape and capacity connected in parallel on both the primary side (12, 13) and the secondary side (14, 15) and connected to a common cold water inlet (KW) and a hot water outlet (30). The use of heat exchangers connected in parallel makes it possible to obtain highly efficient heat transfer from low capacity, standardized heat exchangers, which require no temperature-limiting saftey devices (DIN 4753, 4747) and are therefore cheaper to install. The heat exchangers (10, 11) in a hot-water system are mounted side by side in a group on an installation frame.

Title: Connector block feed station and cable harness discharge station
Inventor: GERST MICHAEL
IPC: H01R43/20
Filed: 1988-04-05
Abstract: The feed station (6) comprises a frame (244) on which connector block fixing devices (344, 346) are positioned on a connector block fitting position. Connector blocks (B) are fed from coils (278) along horizontal paths (272) in the frame (244) at a connecting block entry level underneath the level of the block fitting position (BP). The front block (B') in each path (272) in the conveyor direction is moved forwards by a pushing piston (310) to a receiving position and is raised from the path by a gripper arrangement (326) in order to fix the block in a respective block holder (340). The pushing piston (310) and the gripper arrangement (326) are mounted on a common carriage (290) which can be displaced horizontally in the frame (244). When a block (B') which is at the front in the conveyor direction is raised by means of the gripper arrangement (326), the next subsequent block (B'') in the conveyor direction is moved forwards into the receiving position. The discharge station (10) is used for clearing away electrical cable harnesses which have been produced by a cable harness production machine. A carrier (510) which can be extended vertically can move along the first path (512), and a second path (26), which is supported by the carrier (510), extends in the horizontal direction and at right angles to the first path (512). The second path carries a pair of cable grippers (24), at least one of which [lacuna] relative to the other gripper (24)... Original abstract incomplete. <IMAGE>

Title: Method of generating mechanical retentions for veneer materials and a high-melting adhesive
Inventor: KOERBER KARLHEINZ PROF DR
IPC: A61C5/77
Filed: 1988-08-22
Abstract: Mechanical retentions are required for veneering dental frames of pure noble metals. For ceramic veneers it is usual to sinter a so-called bonder in a separate operation in the pottery kiln. The inventive method avoids this additional time expenditure in that a new high-melting adhesive is melted in one operation with soldering of the frame in the open flame. At the same time, the particle size and shape of the new adhesive and hence its retention-forming surface are matched to the ceramic or plastic veneer material.

Abstract: A double-vessel mashing mechanism is designed in such a way that a mash and lauter tun (1) takes the form of an annular cylinder. A mash and wort boiler (3) is arranged coaxially inside the space enclosed by the mash and wort tun (1) in such a way that part of its cylindrical circumference (2) also forms the inside wall of the mash and lauter tun (1). In order to be able to drive a loosening and draff discharging machine (27) inside the mash and lauter tun (1), which is arranged in an annular fashion, using a concentrically arranged mash and lauter tun drive (23), a section of the circumferential wall (2) of the mash and wort boiler (3) is designed to be movable and acts as a sealing wall (29). The sealing wall (29) is fixedly connected to arms (31) of the loosening and draff discharging machine and therefore rotates concomitantly with the latter.

Abstract: One object of the present invention is therefore to demonstrate a pressure-measuring electrical lead which has improved response sensitivity, lifetime and efficiency for the determination of the input fineness to a desired level, which is, furthermore, simply structured and thus less costly in its production. The pressure-measuring electrical lead according to the present invention is characterised in that it has a flexible, insulating layer of plastic with a row of channels in a network, this layer being applied onto a flexible, electrically conducting layer of silicone rubber. A further object of the present invention is the demonstration of a method by means of which a pressure-measuring electrical lead is obtained which has a sufficient adhesive strength between the electrically conducting body and the insulating body, in order to obtain here sufficient response characteristics. The pressure-measuring electrical lead according to the invention is produced in that a silicone adhesive, to which toluene and silicone ink are added, is applied onto a flexible layer of an insulating material containing silicone, which is penetrated by a series of channels, in that this insulating plastic layer is then placed onto an elastic, vulcanised layer consisting of an electrically conducting substance, and in that the insulating plastic layer and the electrically conducting ... are then ...

IPC: F02M51/08
Filed: 1988-09-14
Abstract: In known electromagnetically actuatable valves, a connecting tube connected to the armature has a valve closing element secured to its other end. The connecting tube has fuel flowing through it, which can exit again in the vicinity of the valve closing element via radially extending openings. To make such tubes additional work steps are required. There is proposed a novel connecting tube intended to assure easy manufacture and simple assembly with minimum weight and maximum stability. The novel connecting tube is provided with a slit extending from one end to the other, which provides the connecting tube with resilient elasticity and provides a large-area hydraulic cross section. The manufacture of the connecting tube can be accomplished easily by rolling of a sheet-metal blank. The embodiment of the connecting tube is suitable for electromagnetically actuatable valves of all kinds.
