Patent DE-3115313-A1 (DE)
Title: Ultrasonic device for sector scanning
Inventor: HETZEL GERT DIPL ING
IPC: G01N29/265
Filed: 1981-04-15
Abstract: In a proposed ultrasonic device for sector scanning, the ultrasonic head can be swivelled within a predeterminable angular range by a motor drive, the motor drive comprising the actual motor drive with transmission and an angle sensor. According to the main patent application P 2941876.6, the angle sensor is connected as an actual-value sensor together with a setpoint generator in a control circuit for the drive motor to achieve an angular movement of the ultrasonic head in the required manner. The actual-value function and the set point function are matched to one another so as to produce a shape equality of the two output functions over fairly large signal ranges within the desired swivelling angle range at the control input itself. According to the additional application, the device specified in the main patent application is modified so that, instead of the ultrasonic head (1), a mirror (101) for reflecting the ultrasonic waves emitted by the ultrasonic head (1) can be swivelled within a predetermined angular range by the drive motor (6). The technical design is thereby simplified. <IMAGE>

Patent DE-3120644-A1 (DE)
Title: Adjustment device for a magnetic probe
Inventor: VALLON RICHARD
IPC: G01R33/02
Filed: 1981-05-23
Abstract: In the proposed magnetic probe adjustment device, two coil-carrying probe bodies are in each case accommodated in a carrier tube, on the one hand in an axially elastically pressing ball joint and, on the other hand, in a radial bearing. The latter has a lower carrying body mounted in the carrier tube, at which carrying body a spherical thrust bearing area for a probe body end is constructed on one side of a connecting axis which is coaxial to the carrier tube and, on the other side, a threaded spindle extending radially to the connecting axis is supported. The thrust bearing area is determined by a generatrix which can be shifted parallel to the threaded spindle axis and is convex with respect to the probe body. The probe body end carries, on the one hand, a threaded sector which engages the threaded spindle and, on the other hand, forms two approximately linear support areas which rest in a point on the thrust bearing area and extend radially to the threaded spindle axis approximately parallel to the connecting axis. The probe tube end which is supported at three points can be adjusted unambiguously and with low friction and the required pressing force and tolerance of fit of the threaded spindle are low.

Title: Method for manufacturing different handlebars for bicycles
Inventor: SCHAUFF HANS DIPL ING
IPC: B62K21/12
Filed: 1981-11-04
Abstract: The invention relates to a method for manufacturing different handlebars for bicycles. Previously, bicycle handlebars were shaped either in one piece or else from two separate handlebar parts in each case by bending such that the handle ends of the handlebars have an optimum position with respect to the frame and the respective person using the bicycle. However, bending is very costly, in particular when handlebars of a different shape and size have to be manufactured. A particularly versatile adaptability and a reduction in the manufacturing expenditure can be achieved according to the invention by virtue of the fact that the handlebar parts are composed in each case of a handle tube and a wing tube and that the position of the free handle tube ends is fixed in relation to the frame by corresponding dimensioning of the wing tube length and handle tube length and those angles at which the handle tube is attached to the wing tube and at which the latter is attached to the fork head.

Title: Process for the regulation of an electrically controllable expansion valve
Inventor: ISERMANN ROBERT DIPL ING
IPC: G05D23/20
Filed: 1982-05-29
Abstract: In a process for the regulation of an electrically controllable expansion valve, in particular in a cold- and/or heat-pump plant, with regulation of the valve via the measurement of physical quantities within the plant, a solution is to be provided by means of which, in particular, the regulation of the expansion valves is optimised in so-called monovalent heat pump plants with fluctuating temperature behaviour, in particular the free adjustability of a characteristic curve being automatically possible at any time. This is achieved in that a microcomputer is associated with the regulating circuit of the expansion valve for its regulation, that the evaporation pressure (P0) is measured and moreover the evaporation temperature ( theta 0) is calculated in the microcomputer, that the temperature of the refrigerant at the evaporator outlet ( theta K) is measured, and the measured data are fed into a regulation algorithm. <IMAGE>

Title: Device for measuring the instantaneous fuel consumption of compression-ignition engines
Inventor: PLATZER DIETER
IPC: G01M15/04
Filed: 1982-07-03
Abstract: In a device for measuring the instantaneous fuel consumption of vehicles driven by compression-ignition engines, the instantaneous fuel consumption values are determined and fed to a display unit by an electronic control device, in which an engine map memory is provided, as a function of the engine speed, the load measured by a sensor and the transmission ratio. To achieve a reproducible measurement result, which cannot be influenced by mechanical loading of the load-measuring sensor, the measure of the load on the internal combustion engine is derived from the exhaust gas temperature.
Patent DE-3228443-A1 (DE)
Title: Retrofit device for obtaining a two-stage flushing in WC flushing cisterns with a float valve at the flushing cistern outlet
Inventor: SCHLEMMINGER JUERGEN
IPC: E03D1/14
Filed: 1982-07-30
Abstract: According to the invention, for the two-stage flushing in WC flushing cisterns with a float valve, one or more containers (2) with a very low dead weight and an adjustable water-inlet and water-outlet opening (10) is attached to the overflow pipe (1), characteristic of each flushing cistern, or is formed in one piece with the overflow pipe. The container (2) can be lowered in the flushing cistern water and has, as a result of its low dead weight, no effect on the float valve when situated in the water. The water-inlet and water-outlet opening (10) in the container (2) is adjustable in size so that the water flows out of the container (2) at a different speed than the flushing cistern water situated all around, after initiating the flushing by means of the actuating mechanism. Consequently, after normal, short actuation of the actuating mechanisms customary for flushing, the water still situated in the container (2) and acting as a weight will lower the overflow pipe (1) to effect valve closure. The entire quantity of flushing cistern water flows out if the actuating mechanism for flushing is actuated for just a little longer. The overflow pipe (1) is then prevented from descending and effecting valve closure at the time of the intended descent and there is then no longer a sufficient quantity of water acting as a weight in the container. <IMAGE>

Filed: 1982-09-29
Abstract: The graphite body (22) has a graphite rib (23) which is wedge-like in section and engages in a correspondingly constructed contact supporting slot (21). In consequence, not only all the axial compression forces but also lateral compression forces can be absorbed. Axial tension is held by means of anchoring pins (25), which are bonded in a positively locking manner in the graphite body (22) and engage in a prestressed manner on the contact support (20). The consequence is an excellent mechanical and electrical connection.   <IMAGE>
Patent DE-3236936-A1 (DE)
Title: Production of two-layered plastic sheathings of tendons with subsequent bonding for prestressed concrete structures
IPC: E04C5/08
Filed: 1982-10-06
Abstract: The invention relates to the production of a two-layered plastic sheathing of tendons, in which the outer, thick layer consists of a hard, impact-resistant plastic, the inner, thin layer consists of a viscous plastic which can be cured only by subsequent reaction. If, during production, the outer layer is applied in the not yet cured state directly to the viscous inner layer, an undesired mutual influencing of the two layers may occur. According to the invention, this mutual influencing is prevented by a band of tension-resistant material being wound onto the inner, viscous layer, and by the not yet cured outer layer being applied to this band.

Title: Device for measuring belt tension
Inventor: KNOLL HANS
IPC: G01L5/04
Filed: 1983-05-14
Abstract: A device serves to measure belt tension, in particular on a V-belt of a stationary engine or of a vehicle engine. A measuring fork (1) is provided in which the belt (20) bears with one side against two spatially fixed stops, in particular rollers (21a, 21b) and with the other side against a movable driver (22) arranged between the spatially fixed stops. The driver (22) is deflected by a piston (12) to which a pressure medium is fed via a line (39) from a supply device spatially remote from the measuring fork (1). Measuring means (25) record the deflection of the belt (20) and the force acting on it. In this arrangement, the piston (12) is part of an open pneumatic system in which the piston position can be adjusted independently of the pressure acting on the piston (12). The device permits especially accurate and easy-to-evaluate measurements of the belt tension. <IMAGE>
