Patent DE-3210174-A1 (DE)
Title: Device for heating liquid or gaseous media
IPC: F24H4/04
Filed: 1982-03-19
Abstract: Heat pumps require for their operation a heat source, the heat of which is raised to a higher temperature in order in another place to heat a liquid or gaseous medium. Water or air supplied to the heat pump generally serves as heat source. This requires certain precautions on installation. This dependence on the environment is reduced according to the invention in that a second secondary exchanger circuit is provided, which is guided through the region to be heated and is connected to the evaporator of the heat pump by a secondary exchanger. As a result, an internal heat circulation takes place which maintains the operation of the heat pump. The device can thus be adapted to the environment. The heating effect is always guaranteed. Construction and functioning of the device are illustrated particularly clearly in Fig. 1. <IMAGE>

Title: Clamping set with cylindrical ring
Inventor: MUELLENBERG RALPH
IPC: F16H57/00
Filed: 1982-08-18
Abstract: A clamping set having at least one inner taper ring with a cylindrical inner circumferential surface and an outer circumferential surface designed as a tapered surface and having at least one outer taper ring with a cylindrical outer circumferential surface and an inner circumferential surface designed as a tapered surface. The taper rings can be clamped together axially by means of axial clamping screws.

Title: Lagging plate
Inventor: GIERKE HEINRICH R
IPC: E21D11/15
Filed: 1982-11-12
Abstract: Roadways and spaces in underground mining and tunnelling are secured by a support system, the support arches of which are each connected via lagging plates which have hooks at the ends for inserting into the support arches. To this end, a plate is connected on the roadway side to a lagging mat which has double hooks which can be inserted in particular at both ends into the support arches. The plate has an external size corresponding to the internal size of the lagging mat so that, when the intermediate space between the individual support arches is completely sealed off in the longitudinal direction of the roadway, further lagging plates can readily be hooked or inserted into the respective support arches. A lagging plate of this type can be placed in such a way as to be sealed off against dust and through-flow by all-around sealing strips, so that these lagging plates are especially well suited to both the normal support system with water influx and the support system with subsequent backfilling.   <IMAGE>

Title: Method and device for displaying emergency exists
Inventor: UEMURO TAKAMITI
IPC: G08B5/00
Filed: 1983-03-18
Abstract: This method relates to the indicator of an escape direction in a building in which a refuge is reached. The method consists in producing an indicator which consists of an underlayer part of an essentially elongated flat shape and of a multiplicity of indicator unit parts which are arranged at a distance from one another in the longitudinal direction on the underlayer part, each of the indicator unit parts having a shape which can be detected by touch and which indicates one of two opposite directions along the length of the underlayer part. The method consists, furthermore, in attaching the indicator to a surface of the building which partly determines a corridor leading to a refuge in such a way that one of the two indicated directions corresponds to the escape direction. A direction indicator is arranged which consists of an underlayer part of an essentially elongated flat shape having a flat surface and a multiplicity of indicator unit parts, which are arranged at a distance from one another in the direction of the longitudinal axis of the underlayer part. Each indicator unit part represents a raised or removed part which is held with the fingers and which has a shape which indicates one of two opposite directions along the length of the underlayer part. If the indicator unit part consists of a multiplicity of indicator units, the latter are arranged differing in size from one another and at a distance from one another on the underlayer part in accordance with the size in one of two longitudinal directions of the underlayer part.

Title: Weight balance for components vertically adjustable on a machine column, in particular of a cross beam, carrying machining units or slide rests, of a machine tool
Inventor: REINHARDT PETER
IPC: B23Q11/00
Filed: 1983-04-11
Abstract: To balance the weight of heavy, vertically adjustable components, in particular of machine tools, the working spaces of the hydraulic cylinders provided for the weight balance are connected to a hydrostatic machine which has a constant displacement volume and is coupled to a second hydrostatic machine having a variable displacement volume. If control fluid is displaced from the working spaces when the cylinders are retracted, the first machine, as a motor, drives the second machine, which, as a pump, forces control fluid into a reservoir. In the opposite case, control fluid is removed from the reservoir, and the second machine, working as a motor, drives the first machine which pumps the control fluid into the working spaces. The pressure in the working spaces or the force exerted by the cylinders is kept constant by the displacement volume of the second machine being set accordingly. In this way, complete weight balance is achieved. <IMAGE>
Patent DE-3314928-A1 (DE)
Title: Electronic circuit for reactive power compensation
Inventor: HOFMANN WOLFGANG DIPL ING
IPC: H02J3/18
Filed: 1983-04-25
Abstract: An electronic circuit for reactive power compensation has a measuring transducer and evaluation circuit for supplying signals which are dependent on the magnitude and mathematical sign of the reactive power and which drive a clock-pulse generator and counting circuits which receive the output signals of the clock-pulse generator. In addition, coding and switching devices which are controlled by the counting circuits are provided for the connection of capacitors having predetermined capacitance values. In order to achieve uniform utilisation and loading of the capacitors, the counting circuits are formed by two counters, each of which receives clock signals from the clock-pulse generator as a function of the mathematical sign of the reactive power, and counts in the same direction, the outputs of the counters which respectively have the same values being connected to the set or reset input of in each case one of a number of bistable circuits whose outputs are connected to the inputs of the switching devices. Once their maximum count value is exceeded, the counters jump back to their initial counting value. In this way, the capacitors which were switched on first by the counters driven in the case of an inductive reactive power are also the first to be reset by the counters which are driven in the case of a capacitive reactive power.

Title: Brush holder for an electrical machine having at least one brush, and having a signal transmitter for reporting wear
Inventor: MEYER URS DIPL ING DR
IPC: H01R39/58
Filed: 1983-06-24
Abstract: For electrical machines having commutators or sliprings, contact brushes are used to extract or supply electrical energy, which contact brushes are subject to continuous wear. The brushes must be replaced from time to time. In order to prevent damage, the replacement must be carried out in good time. For this reason, wear indication devices have been developed for brush holders, which devices operate using audible or visible signals. The known embodiments are to some extent technically costly and to a large extent are not sufficiently functionally reliable in the long term. In order to avoid these disadvantages, a terminal element for the connection of a signal transmitter is provided in the case of the present wear indicating device having a prestressing spring (which can be rolled up) for the contact brushes, which signal transmitter can be made contact with directly only by a rolled-up part of the spring which corresponds to brush wear which does not exceed a predetermined extent. This ensures in particular that, even in the event of a disturbance of the electrical connection between the contact terminal and the prestressing spring, for example as a result of dirt contamination, a signal is transmitted.
