Title: Add-on spacer with vertical locking for a safety belt in motor vehicles
Inventor: HERR MICHAEL
IPC: B60R22/19
Filed: 1984-12-29
Abstract: The add-on spacer with vertical locking for a safety belt in motor vehicles serves to distance the spring action of the retraction mechanism of the safety belt, which is perceived as an unpleasant pressure, from the shoulder, the collar bone and the base of the neck by placing the saftey belt in the guide of a lifting arm once it has been put on, which lifting arm is mounted on the upper belt fastening, thereby distancing the belt from the said parts of the body without impairing the safety it provides.
Patent DE-3500975-A1 (DE)
Title: Connecting device for two housing parts of an automatic switch
Inventor: BOEKER GUENTER DIPL ING
IPC: H01H71/02
Filed: 1985-01-14
Abstract: The housing parts (2, 3), which rest on one another and are provided with common through-holes (4), are held together by means of a connecting part (1). The latter is constructed as a double T-shaped stamped sheet-metal part having an upper flange (1a) and a lower flange (1b), which flanges are connected to one another via a web (1c) which is provided with a longitudinal slot (1d). The housing part (2) is provided with two key surfaces (2) which narrow the through-hole (4), so that only one plug-through slot remains free for the lower T-shaped end of the connecting part (1). After a 90 DEG  rotation about its longitudinal axis, the latter strikes with the lower flange (1b) against integrally formed stop segments (2e) and at the same time engages with the lower flange (1b) on both sides, via the key surfaces (2d), in undercuts (2f). In consequence, it is no longer possible to pull the connecting part (1) out. A torque acting in the sense of rotating further on the upper flange (1a) causes the web (1c) to twist in the region of the longitudinal slot (1d), and causes the connecting element (1) to shorten. In consequence, the housing parts (2, 3) are firmly pressed onto one another and are reliably mutually connected to one another. The connecting device can be used advantageously in the case of installation apparatuses instead of riveted connections, since the housing parts need to be accessible from only one side, particularly during installation.

Title: Pipe clamp
IPC: F16L3/12
Filed: 1985-02-22
Abstract: The invention relates to a pipe clamp having an annular clamp body whose inside is covered by means of a rubber-elastic insert and whose ends bound a closable opening, the one end pointing outwards and being provided with a holder for a closing screw, while a connecting body which holds the closing screw and is constructed as an angled piece is pivotably supported in the other end, the one limb of which connecting body is arranged on the outside and the other limb of which connecting body is arranged on the inside of the clamp body and is covered by the insert. The invention is intended to create an improvement in the automatic nature of closing of the pipe clamp. This is achieved in that the end region of the outwardly pointing end of the clamp body has a bend which expands its opening and forms an angle of 30 DEG  with the outer limb of the angled piece. <IMAGE>
Patent DE-3508583-A1 (DE)
Title: Water aeration appliance
Inventor: JAEGER SEBASTIAN
IPC: B01F3/04
Filed: 1985-03-11
Abstract: The invention is based on a water aeration appliance in which an elastically deformable layer positioned on a substrate is provided with a multiplicity of slit-like expandable perforations for the passage of the air into the water. In order to achieve particularly fine, small and at the same time uniform air bubbles, according to the invention the perforations narrow towards the outside of the layer. Advantageously, the slit edges at the same time run obliquely to the surface of the layer, but especially in a symmetrically v-shaped manner.

Patent DE-3515366-A1 (DE)
Title: Device for better utilisation and distribution of the thermal energy released in heating systems
Inventor: INGERSLEBEN CORNELIUS VON
IPC: F24D12/02
Filed: 1985-02-01
Abstract: A closed air supply system which is operated by a blower is used to supply warm air to a consumer through an air heat exchanger surface in or around a component, of a heat generator, conducting exhaust gas. The blower is controlled by an adjustable flue gas thermostat switch so that the energy contained in the flue gases can be used without any problem down to a lower limiting value which results from the structural conditions. Particularly avoided in this case are condensation problems which frequently arise in the case of direct installation of water-conducting heat exchanger surfaces in the exhaust gas flow. The use of simple components renders possible here a real optimisation of the efficiency of heat generators.

Title: Apparatuses and units for using thermoelectric effects as a current generator or as a heat pump
Inventor: BOJAK KURT DIPL ING
IPC: H01L35/28
Filed: 1985-07-03
Abstract: The effectiveness of the previously known thermoelectric devices is greatly reduced by heat flow losses in the element limbs. The installation of electrical capacitors in the limbs, linked to a method of operation using a current which is variable with time, impedes the heat flow, as is shown on a number of arrangement examples, and allows considerably improved efficiencies to be expected for corresponding technical designs.
Patent DE-3526074-A1 (DE)
Inventor: LEONHARD ROLF DR
IPC: F01N3/10
Filed: 1985-07-20
Abstract: An apparatus for the burning of solid particles, especially soot particles, separated from the exhaust gas from internal combustion engines has a rotationally symmetrical combustion chamber which coaxially adjoins an ignition burner connected with it by a flame transfer orifice. Fuel and air are metered to the ignition burner through an additional-air line and a fuel line and, as a prepared mixture, they are ignited in the ignition burner and enter the combustion chamber through a flame transfer orifice. In the combustion chamber an exhaust gas partial stream enriched with the solid particles is introduced, and, after the solid particles have been consumed together with the additional air put into the combustion chamber, the exhaust gas is then discharged again as cleaned exhaust together with the remaining combustion products through an outlet tube.

Patent DE-3528409-A1 (DE)
Title: Method and device for monitoring the load state of a rotating mechanism which is driven by a field-oriented rotating-field machine
Inventor: TIMPE WOLFGANG DIPL ING
IPC: H02P21/00
Filed: 1985-08-07
Abstract: The rotating mechanism of a mill, of a roller works, of a conveyor machine etc. is driven using a field-oriented rotating-field machine. In order to protect the mechanism and/or the material being processed, its condition is monitored and the monitoring signal is formed which is dependent at least on the torque acting on the mechanism. The component of the stator current at right angles to the field and, possibly, in addition, the field angle and the field frequency of the rotating-field machine are picked off on the field-oriented control device of the rotating-field machine as equivalent variables for the mechanical opposing torque, the rotation angle and the rotation speed of the mechanism. Thus, for example, the "frozen charge" state of the filling material of a tube mill can be detected without mechanical sensors. <IMAGE>

Title: Process for reheating semifinished products cast in a continuous casting installation and apparatus for carrying it out
Inventor: FELDMANN HUGO DR
IPC: F27B9/22
Filed: 1986-01-16
Abstract: A process for reheating semifinished products which have been cast in a continuous casting installation and are to be brought into further-processing installations. The semifinished-product lengths (HK) are supplied to a store in the direction of their longitudinal axis or transversely to the longitudinal axis and then moved from this store to reheating furnaces according to the requirement of the further-processing installation, and heated therein to the further-processing temperature. Cooled semifinished-product lengths (HK), which are situated in the store, are brought, during their transportation from this store to the further-processing installation, into heat transfer contact with the warm semifinished-product lengths (HW) which are being transported from the continuous casting installation to the store. This heat transfer contact is produced, for example, by the cold semifinished-product lengths (HK) being transported over a supporting grate 2 which is arranged at a distance above a supporting grate 1 over which the warm semifinished-product lengths (HW) are transported in the opposite direction. <IMAGE>
Patent DE-3601427-A1 (DE)
Title: Device and method for operating periodic sorption apparatuses
Inventor: MAIER-LAXHUBER PETER
IPC: F25B17/08
Filed: 1986-01-20
Abstract: The invention relates to devices and methods for operating periodic sorption apparatuses in heating systems. To remove heat from the sorption apparatus, a heating circuit is divided up into a condenser circuit for taking up condensation heat and a sorption circuit for taking up sorption heat. A regulating device controls the flow of heating water through the two circuits. Heat is removed, with priority, via the condenser circuit. In the event of a higher heat demand, the sorption circuit is switched on. To avoid dangerous overpressures, heating water can run out of the sorption circuit without residue.

Title: Stop device for door wings having a door closer
Inventor: SPECKAMP HANS-RAINER DIPL ING
IPC: E05C17/28
Filed: 1986-02-08
Abstract: The stop device for a door wing equipped with a door closer cooperates with a sliding piece which is connected in the manner of a rotary joint to one end of an actuating arm coupled to the closer shaft of the door wing and which engages into a guide rail. This guide rail is assigned a holding unit fixing the sliding piece in a specific open position. In order, on the one hand, to make it possible to integrate the holding unit into the guide rail and, on the other hand, to make it possible to override the stop position both in one and in the other direction as a result of increased exertion of force on the door wing, the holding unit has a catch boss loaded in the blocking direction by a spring member and engaging on the sliding piece.

Title: Bearing lubrication arrangement
Inventor: EMMENTHAL KLAUS-DIETER DR ING
IPC: F01M1/10
Filed: 1986-02-12
Abstract: The lubrication arrangement for the bearing (5) of a rotating mass (3) mounted on an eccentric collar (2) of a drive shaft (1), in particular the rotating mass of a displacer of a scroll-type displacement machine used as a charge-air compressor (supercharger) for internal combustion engines, has longitudinal lubricant feed and discharge passages (12, 15) in the drive shaft. These passages are connected to the bearing (5), which is sealed off from the outside by ring seals (6), by transverse holes (13, 14) arranged in the region of the eccentric collar, giving rise to a flow of lubricant through the bearing. To prevent impurities of higher specific weight, such as oil sludge or the like, fed in with the lubricant from settling in the bearing without the possibility of being carried away, a replaceable insert (18) is to be held in the lubricant feed passage (12) arranged in the drive shaft (1), this insert having a space (19) through which the lubricant flows and which has, on its circumference, means which collect the impurities, such as a body consisting of a material of sponge-like porosity. <IMAGE>

Title: Method for processing a measurement value present as a frequency
Inventor: HANGAUER WILFRIED DR ING
IPC: G01D5/243
Filed: 1986-03-01
Abstract: Method for processing a measurement value which is present as a frequency and which fluctuates between limit values, in that a first electrical signal which is variable with the ratio of this frequency with respect to a reference frequency is formed which, in turn, has the same ratio to a predeterminable electrical reference value. The application of the method in a speed control system of an asynchronous motor, particularly for an exhaust-gas fan, is essential to the invention. In the circuit for carrying out the method, two operational amplifiers 51 and 55 connected to their different inputs are provided, the two input pairs being connected to in each case one capacitor (47, 38), one of which is connected to earth and the other one of which is connected to a voltage source which exhibits two extreme values per period of the frequency of the actual-value transmitter and is clocked at the frequency of the actual-value transmitter between the two extreme values, the voltage excursion between the extreme values being predeterminable but constant. <IMAGE>

IPC: G06F3/033
Filed: 1986-03-29
Abstract: The invention relates to a system for measuring the length of resistor ladders, consisting of at least one resistor ladder (RB) on which a measurement point (PCU) is located, the position of which is measured in the longitudinal direction of the resistor ladder (XPOS) and in a preferred embodiment is also measured perpendicularly and obliquely with respect to the direction of the resistor ladder by determining the subresistances (RB1 + RB2 = RB) on both sides of the measurement point, in particular in a contactless fashion. For this purpose, in accordance with the prior art, a voltage injection into the resistor ladder is made at the measurement point and a measuring device is connected to the resistor ladder on both sides of the measuring point. The object of the present invention is to perform the most accurate measurement possible, to obtain a measurement result for the length measurement which is independent of sources and sinks occurring along the course of the resistor used for the resistance measurement, also of coupling capacitances of the measuring device, of the internal resistance of the signal feed used and, if appropriate, of temperature influences. This technical object is achieved by a simulation network which is connected to the resistor ladder on both sides of the measuring point and which, ... by compensating by means of a fed manipulated variable on both sides of the measuring point or voltage injection of the measuring point, ... corresponding conducting properties of the resistor ladders used for the length measurement or ... on both sides of the ...

Patent DE-3618976-A1 (DE)
Title: Heat-insulating panel with high vacuum and compression bodies in the interspaces
Inventor: VIERT KLAUS-PETER DR
IPC: E04B1/80
Filed: 1986-06-05
Abstract: In this invention, the multilayer heat-insulating panel for facades and roofs is made of at least two parallel individual panels of any weather-resistant, vacuum-tight, pressure-resistant and rigid material, however in particular are metal, a high vacuum existing between the individual panels. The compressive force is absorbed by compression bodies which are located uniformly distributed between the individual panels. The compression bodies transmit only a very small amount of heat if they are reduced to the required dimension. Otherwise, heat is only transferred by heat transmission at the edge connection and by radiation. The radiation heat loss is minimised by polishing or metallising the interior surfaces of the individual panels or by inserting special insulating material of a type already known. Very low heat-transmission coefficients are to be expected for thermal insulating panels produced in this manner for facades and roofs, and an important contribution to energy saving in buildings can thus be made. This insulating panel can also be used as a cold-insulating panel in cold stores, refrigerators or freezer chests.
