Patent DE-3048928-A1 (DE)
Title: Cylinder overpressure relief valve with electropneumatic switch - for initiating reduction or suppression of fuel supplied to the injector of affected cylinder
Inventor: GENTSCHEFF JORDAN DIPL ING
IPC: F02B3/06
Filed: 1980-12-24
Abstract: The pressure relief and control system is applicable to diesel engines. The object is to act on the fuel supply to the affected cylinder as well as to relieve the overpressure. Each cylinder (1,2) has a pressure relief valve (10) with a piston (14) which acts against a calibrated spring (13). If the cylinder pressure exceeds the safety level set by the spring the valve opens and the cylinder gases escape to atmosphere via a chamber and vent pipe (15,16). A pneumatic connection (21) from the relief valve chamber (15) connects with an electropneumatic switch (20) whose electrical contacts are monitored by an electronic engine controller (5). When the contacts close the controller acts to limit or delay the fuel injection to the affected cylinder by operating on the injector (3) control valve (4). If the overpressure persists it then acts to close the fuel supply (7,8,9) to the affected cylinder. The arrangement is fast acting with short travel distance for the electrical contacts.

Title: Rotational speed limiting safety device
Inventor: NAKAZAWA YUKI
IPC: H01H35/10
Filed: 1981-05-21
Abstract: A safety device for limiting the rotational speed of a rotating shaft driven by an electric motor (2) is designed such that a supply path (4) of an electrical supply circuit for the electric motor is interrupted by an interrupter (10) which is held in a rotating part (5) and protrudes outwards as a result of the centrifugal force acting on it so that dangerous rotational speeds are prevented. The interruptor is held such that it can move in a radial hole in the rotating part and is held by a tensile force by a helical spring (7) which is connected fixedly at one end to the rotating part. An adjusting screw (11), which is a cylindrical part, is provided in order to pretension the interruptor against the clamping force of the spring. The response rotational speed, above which the interruptor is forced outwards and interrupts the supply circuit, can be selected at will by changing the position of the adjusting screw. Changing the position of the adjusting screw simultaneously changes the distance of the centre of gravity of the interruptor from the centre and the initial tensile force of the spring. <IMAGE>

Title: Mounting aid for fastening insulating-material webs
Inventor: WEISS GUENTER
IPC: E04F21/18
Filed: 1981-07-25
Abstract: For the heat insulation and/or sound insulation of buildings, in particular of building roofs and the exterior walls, use is very often made of insulating-material webs which consist, in particular, of mineral wool, preferably of rockwool, and are coated, at least on one side, with an aluminium or plastic film which is as tear-resistant as possible. During storage and transportation, the insulating-material webs are rolled up in a predetermined width and length to form rolls. Once they are rolled out, the relevant coated film projects on both longitudinal sides beyond the actual insulating-material web and thus forms, on both sides, longitudinally running border strips, with the aid of which the insulating-material webs can be fastened on the relevant load-bearing members of a building. Fastening takes place by means of nails, cramps or the like. In order to simplify attachment or fastening of such insulating-material webs to a considerable degree and also to make it possible for this to be carried out by one person, the invention proposes an aid with two clamping plates, between which a part of the relevant border strip can be clamped, a clamping plate being provided with a fastening element.

Title: Fish ladder
Inventor: BOERNER ALFRED
IPC: E02B8/08
Filed: 1981-08-27
Abstract: A fish ladder is proposed which consists of a pipe (1) with several transverse retaining discs (2). The retaining discs have passage openings (3) in the lower area and overflow openings (4) in the upper area. Longitudinal slots (5) are preferably provided on the top side of the pipe (1) along a generating line. The retaining discs can be inserted into the pipe (1) through the longitudinal slots (5). The retaining discs are mounted by means of an essentially vertical, eccentrically arranged pivot (6), the result of which is that torque acts on the retaining discs and holds them transversely when water flows in. A common turning device enables several retaining discs or all retaining discs to be turned simultaneously. This enables the fish ladder to be cleaned in a particularly simple manner. An immersion piece (15) is preferably provided at the top end of the pipe (1). The fish ladder according to the invention is thus of simple construction, is easy to produce and easy to clean and can be adjusted to the individual requirements. <IMAGE>

Title: Method of producing large-area modular silicon bodies
Inventor: GRABMAIER JOSEF DR RER NAT
IPC: H01L31/0392
Filed: 1982-03-22
Abstract: In a method of producing large-area modular silicon bodies, a carrier body having a net-like structure and made of a fibrous material (5) which can be wetted by silicon is used and the coating with molten silicon is carried out in such a way that, because of the high surface tension of the molten silicon, a thin silicon layer is formed in the meshes of the net. The carrier body used has at cyclic intervals mesh rows (3) made of a material which cannot be wetted by molten silicon, with the result that a silicon layer cannot form in these regions (3). After coating, the silicon body is separated at the points (3) into the individual solar cell arrangements (1, 2). <IMAGE>

Title: Energy-absorbing accumulator system
Inventor: ROSEL VALENTIN
IPC: F28D20/00
Filed: 1983-03-09
Abstract: Energy is absorbed and stored by the energy-absorbing accumulator system. The coiled tubing (1), the jet tube (3) and energy-transferring compound (5) are installed in ground bores (2) at a depth of 1.5 to 2.5 m. The solar and wind heat absorbed by the open-air absorber (16) is transferred via the coiled tubing (1) to the ground accumulator (22) and stored. The rainwater is fed from the rainwater tank (6) by the rainwater pump (9) to the pump injector (8) via the rainwater pressure line (14) to the water jet tube. The ground accumulator (22) is soaked due to this arrangement, and the storage capacity is substantially increased. Only a small floor area is required for the energy-absorbing accumulator system, since it is only the quantity of energy of the 2 winter months that is stored. If the brine temperature in the open-air absorber (16) is above the brine temperature in the coiled tubing (1), the temperature-difference control (18) switches on the circulating pump of the open-air absorber, and the air and solar heat are fed to the ground accumulator (22). This patentable energy-absorbing accumulator system can be used to heat a dwelling by means of a brine/water heat pump in a monovalent fashion. The latent heat of the soaked ground accumulator is utilised at the same time in the energy-absorbing accumulator system. <IMAGE>
