Title: Positive-displacement machine for compressible media
Inventor: EMMENTHAL KLAUS-DIETER DR ING
IPC: F01C1/02
Filed: 1987-10-30
Abstract: A positive-displacement machine for compressible media is described, with at least one displacer chamber (8) located in a stationary casing and designed like a spiral slot, and with a band-like or tongue-like displacer (9), also of spiral shape, allocated to each displacer chamber and held on a disc-shaped rotor (3) that can be driven eccentrically with respect to the casing. The eccentric mounting of the rotor is such that, during operation, each point on the rotor performs a circular motion restricted by the peripheral walls of the displacer chamber, with its eccentricity as the radius. The casing comprises two parts (2a, 2b) divided essentially in the plane of the disc-shaped rotor (3), which are connected to each other by axially aligned retaining means. In order to reduce the radial dimensions of the displacer machine, the retaining means are to be formed of at least one retaining element (10), connecting the two parts (2a, 2b) of the casing and running essentially axially, which is located in a peripheral plane radially adjacent to a central guide bearing (6) of the rotor (3) and engages through a through-hole (14) made on the rotor and connecting the two working chambers (15, 16) formed on either side of the rotor. <IMAGE>

Patent DE-3813509-A1 (DE)
Title: Sliding system, especially for baking ovens
Inventor: THUEMLER MANFRED DIPL ING
IPC: F24C15/16
Filed: 1988-04-22
Abstract: In order to prevent the danger of burns, in the case of known baking ovens, so-called baking carriages are used to extend or retract all the slide-in parts, which are situated one on top of another, jointly by means of motor-driven cranks and levers. It is not possible to select individual baking storeys. The new sliding system permits the separate actuation of each baking storey with very simple means. Via a motor-driven threaded rod (2), a driving running rail (9) is extended or retracted by means of a nut (10) and precisely guided running wheels (7). On the opposite muffle side wall there is situated a freely rotatable running rail which is mechanically connected via the slide-in parts to the driving running rail (9). Each sliding storey of the baking oven can be equipped in this manner and can be individually actuated by means of electrical switching elements. The new sliding system is suitable for installation in baking ovens with very different types of heating and can be used both in free-standing domestic electric cookers and in fitted baking ovens or built-in electric cookers. <IMAGE>

Title: Training couch
Inventor: RESCH HANS
IPC: A63B21/062
Filed: 1988-04-29
Abstract: In order to be able selectively to train parts of muscles, especially of the extremities of the human body, without simultaneously stressing adjoining parts of muscles, a training couch is provided which consists of a framework (1), a couch surface (2), an adjustable back part (3) and a grip system (4). A box frame (6) is positioned laterally next to the couch surface (2, 3), and a vertical pipe (7) is mounted thereon. A carriage (8) is supported in a vertically adjustable manner on the pipe (7). Fixed on the carriage (8) by means of a pivot bearing (9) is a crank (10) with an adjustable cross-piece (11) extending over the couch surface (2, 3). Pads (12) transmit the forces to the extremities over a large area and so increase comfort. A weight block with plug-in weights serves as a force generator (15) and is connected to the carriage (8) via a cable pull (13) which is guided over deflection rollers (14, 18). Finally, an adjustable force and travel measuring device (16), interacting with the carriage (8), is provided and, under computer control, monitors the forces, travels and frequencies of the exercises carried out by the person training. Thanks to this force and travel measuring device (16), not only isometric but also isotonic and isokinetic exercises can be carried out with one and the same appliance. <IMAGE>

Title: Standard light source
Inventor: KESSLER MANFRED PROF DR MED
IPC: G01J1/08
Filed: 1988-05-13
Abstract: The invention relates to the use of a radioluminescent material together with a radioactive radiation source as a standard light source, especially for relatively small light intensities. It is especially proposed to use a so called "beta-light" in which tritium enclosed in a glass container and which emits beta radiation excites radioluminescent materials, especially zinc sulphide, applied to the inner walls of the vessel to luminesce. Radiation sources of this type are characterised by high stability and the ability to calculate the light power well as a function of time. They are particularly suitable as standard light sources in physiological measurements, for example in tissue photometry. <IMAGE>
Patent DE-3816596-A1 (DE)
Title: Indicator element of solid constituents
Inventor: THEDIECK FRANZ REINER DIPL PHY
IPC: G01N33/52
Filed: 1988-05-16
Abstract: Hitherto, it has not been possible to make the state "thawed" simply and clearly visible in individual packages of deep frozen goods, in particular foods. According to the invention, this problem is solved by one or more indicator elements being integrated into the individual packages; the build up, in principle, of such an element is shown in Figure 1. Such elements contain solid materials 2 which permanently change colour, for example from green via yellow to red, when liquid, in particular pH-neutral water, acts on the elements from outside (corresponding to the arrows in Figure 1). These materials 2 are covered by one or more layers 1 which comprise material which is swellable and/or soluble in water, for example gelatine and/or cellulose film. The period of time which elapses from the commencement of the action of water until the material 2 changes colour can be preset within wide limits by selection of the materials and the composition of the layer or layers 1. The elements are generally suitable for monitoring water-sensitive goods. <IMAGE>
Patent DE-3817784-A1 (DE)
Title: Method of operating a chasing machine, and chasing machine for carrying out the method
Inventor: JULIUS ROLF DIPL ING
IPC: B23D1/26
Filed: 1988-05-26
Abstract: In chasing machines, the actual dimensions of the machined metal strip have hitherto been determined by hand when the strip is stopped. The tools are re-positioned if required, likewise by hand, in accordance with this measuring result. This method reduces the productivity and leads to large measuring tolerances in the machined metal strip. The novel method is intended to avoid these disadvantages. The novel method is characterised in that the actual dimensions are recorded in a contactless manner by means of sensors (7) continuously or virtually continuously in the strip running direction behind the tools (33, 34, 35) during the passage of the metal strip (2) through the chasing machine (1), in that the actual sizes recorded are fed to a control computer unit (6) and are compared there with predeterminable, stored desired dimensions and control parameters are calculated as a comparison result, and in that the tools (33-35) or their tool holders (3) and/or tool slides (4) are displaced and positioned in accordance with the control parameters individually or in groups in a remote-operated manner by servo devices (31, 41, 51). In the novel method, the measuring of the machined strip and the adjustment, if required, of the tools are automatically effected in a closed control circuit. The novel method is especially suitable for the operation of chasing machines. <IMAGE>

Patent DE-3823914-A1 (DE)
Inventor: KUHLMANN KLAUS
IPC: H04Q11/04
Filed: 1988-07-14
Abstract: A method for transmitting equipment-specifying program parameter data from a communications installation to communications terminal equipment. The method provides for transmitting program parameter data from a communications installation to a plurality of communications terminal equipment connected thereto and is based on a message-oriented transmission protocol that is used in the sense of an information exchange in the signalling channel between the equipment. In the communications equipment, the input and output devices as well as the procedures of performance features and local performance features are essentially controlled with the assistance of the program parameter data. A transmission of program parameter data is initiated either by a parameter request message transmitted from the communications terminal equipment or by an internal request of the communications installation. In a start of parameter message, address and parameter defining criteria are transmitted from the communications installation to the respective communications terminal equipment. Subsequently, the program parameter data embedded into a parameter message are transmitted to the respective communications terminal equipment and are stored in them.

Title: Washing machines with a water-softening device
Inventor: HEISSMEIER WALTER DIPL PHYS
IPC: D06F39/00
Filed: 1988-07-27
Abstract: Washing powder should not inadvertently be introduced into the salt vessel of the water-softening device by the customer. In a known washing machine, the washing-agent flushing-in tray and the filling connection for the salt vessel are arranged next to one another, so that the possibility of confusion cannot be excluded. By means of the invention, incorrect operation is made more difficult or the customer's attention is drawn to the fact that he is about to execute such an incorrect operation. By introducing a funnel forcibly into the closed salt vessel, an automatic spring flap, rotary shutter or conical plug is opened. The force fit can also be overcome by foot operation instead of by means of a funnel. Washing machines with water-softening devices are used primarily in areas with very hard mains water.

Title: Circuit arrangement for bus monitoring
Inventor: HORST HARALD DIPL ING
IPC: H02J13/00
Filed: 1988-08-06
Abstract: A A-bus system is divided into n regions. Each region has a monitoring device (1) with corresponding switching device (2). In the case of the transmission of time-division multiplex signals over the A-bus system, all switching devices are switched to that they bypass their monitoring devices. In the event of short circuit or interruption within the A-bus system, the monitoring device which no longer receives any signal switches off and the corresponding switching device switches over to a parallel B-bus system. The time-division multiplex signals are now carried by the parallel B-bus system and, after the region in which the fault arose, fed back onto the intact A-bus system. <IMAGE>

Title: Method of controlling pests on plants
Inventor: SCHAETZLEIN HELMUT
IPC: A01N59/00
Filed: 1989-01-25
Abstract: To control pests on plants, in particular grapevines, synthetic crop protection products have hitherto been used as the rule, but these products result in severe pollution of the environment. Moreover, in viticulture, their use results in a lower wine quality. These disadvantages are avoided according to the invention by using an aqueous solution containing hydrogen peroxide (H2O2) or ozone (O3) as crop spray for this type of pest control. If commercially available hydrogen peroxide in a concentration of 35% is used, the hydrogen peroxide concentration in the aqueous solution which acts as crop spray is preferably in the range of approximately 1-5%. To improve the effectiveness of the crop spray, enhancing active substances, agents for strengthening the plants and environmentally friendly active substances for weed control can be admixed to said spray mixture.
