Title: Manually operated mechanical 90 DEG  rotary drive with releasable 90 DEG spring return for quick-closing fittings
Inventor: SAND FRIEDHELM VAN DE
IPC: F16K31/54
Filed: 1981-02-14
Abstract: The invention relates to a manually operated mechanical 90 DEG rotary drive with releasable 90 DEG  spring return which can be attached to fittings with a 90 DEG  range of rotation to give quick-closing fittings. The technical problem is to provide a rotary drive which does not require an external energy source and in which the torques required for the return are blocked by a mechanical system until released. This object is achieved in the invention (see, in this connection, drawings No. DA-001 and DA-002) by virtue of the fact that, by means of a threaded spindle (1) and a rack drive (2, 3, 4), two compression springs (5, 6) are stressed and, simultaneously, toggle levers (7, 8, 9) are extended, the said levers preventing the springs from relaxing after a 90 DEG  rotation has been reached. When the threaded spindle (1) has been turned back and the toggle lever (7, 8, 9) has been displaced, the hindrance to the springs is removed and they are allowed to relax. Racks (2, 4) and pinion (3) convert the rectilinear motion into the rotary motion. These quick-closing fittings are used as a safety device in systems used for storing, transporting or distributing gases or liquids to avoid uncontrolled escapes of gas or liquid. <IMAGE>
Patent DE-3105609-A1 (DE)
Inventor: HENCH HANS
IPC: B29B13/06
Filed: 1981-02-16
Abstract: A device for the dehydration and drying of solids, especially granulated plastic materials, in the form of a mixture of granulate and water. Water passes through a curved sieve by an air current that flows in the direction in which the water passes through the sieve and also flows along the sieve. The mixture of granulate and water is delivered to the curved sieve through a delivery channel and whirled, by the energy of the air current, over the curved sieve and conveyed to an outlet duct, at the end of the curved sieve. On the curved sieve, an air jet that runs at an angle to the sieve, is directed for the admission of the air current. The mixture of granulate and water that is carried along by the air current, hits the curved sieve at an angle ranging, approximately between 25 DEG  to 75 DEG  in relation to the curved sieve. In the direction of flow, behind the air jet, is a cover which covers the curved sieve. The cover is adjacent to the rear wall of the air jet, and extends to the outlet passage. The cover is mounted to guide the granulate executing a shuttling rebound movement between the cover and the curved sieve.

Title: Limit detector for electrical resistances
Inventor: SCHOEPE RAINER ING GRAD
IPC: G01R27/02
Filed: 1981-03-19
Abstract: The invention relates to a device by means of which the range of tolerances of electrical resistances can be checked. The device indicates by means of a simple good/bad indication whether the measured resistance is within the tolerance range set. When electrical resistances are manufactured, particularly in the case of coils, relays, transformers and so forth, it is of importance, on the one hand, that the value of the resistance is within two limits and, on the other hand, the accurate value does not need to be determined precisely. It is therefore of advantage to use only a good/bad indication. The device determines the percentage deviation from the set point and converts it into a good/bad indication. The drawing shows an illustrative embodiment.   1. This coding switch is used for setting the set point of the resistance to be tested. 2. It is possible to set other tolerance ranges by simply switching over.   3. Good/bad indication by light-emitting diode.   4. Acoustic signal transmitter.   5. Test sockets.   <IMAGE>

Title: Operating procedure for a vehicle navigation device and arrangements for carrying out the procedure
Inventor: AUER WERNER DR ING
IPC: G01C21/12
Filed: 1981-03-21
Abstract: This navigation arrangement contains a displacement sensor for generating signals indicating the vehicle movement, and a course gyro for continuously detecting the alignment of the vehicle compared with a reference direction. To eliminate a course error produced by the drift when the vehicle is stopped, the angular change of the gyro in the angle determination between the alignment of the vehicle and the alignment of the course gyro are not taken into consideration when the displacement signals are missing; however, the system additionally monitors whether this angle changes more quickly than is possible due to the maximum drift plus a safety margin. If this is so, or if displacement sensor signals occur again, vehicle travel is assumed and the angular changes are no longer suppressed. <IMAGE>

Title: Instant (instantaneous developing) camera having an electric motor drive
Inventor: EBNER ARNO
IPC: G03B17/52
Filed: 1981-05-08
Abstract: A picture gripper (2) is moved to and fro by a toothed wheel (11) and drives via the driver (11a) a control wheel (6) which is provided with a contact layer (7) and an insulating cutout (7a). Bearing against the contact layer (7) are contact arms (4a and 5a), forming a first contact pair, of a motor protecting switch (circuit-breaker) (3, 4, 5), on which there are integrally formed contact arms (4b and 5b) which form a second contact pair of the motor protection switch (3, 4, 5). A pin (2b) of the picture gripper (2) and a finger (1d) of a releaser (1) act on the contact arm (5b). Upon actuation of the releaser (1), the contact arm (5b) of the second contact pair (4b, 5b) is released to close by the pin (2b) of the travelling picture gripper (2), but continues to be held in the open position by the finger (1d) of the pressed releaser (1). When the releaser (1) is let go, the second contact pair (4b, 5b) is then closed and the motor drive is switched on. The driven control wheel (6) also closes the first contact pair (4a, 5a) via the contact layer (7). Upon moving back, the picture gripper (2, 2b) opens the second contact pair (4b, 5b), and after a revolution of the control wheel (6) the insulating cutout (7a) opens the first contact pair (4a, 5a) and thus the motor protection switch (3, 4, 5), with the result that the motor circuit is interrupted. <IMAGE>

Title: Device for cleaning the surface of a pivotable machine element
Inventor: OLESOVSKY JAROSLAV DIPL ING
IPC: F28G1/16
Filed: 1981-07-02
Abstract: The invention relates to a device for cleaning the surface of a pivotable machine element with a cleaning medium that is supplied by a cleaning nozzle, which device is arranged on a pivotable cleaning arm, in particular for the heat exchanging surfaces in the rotor part of a regenerative rotary heat exchanger. In the device according to the invention, a pivotable cleaning arm can be adjusted at various angles by an actuator on the rotor end face, the outer limit position of the cleaning arm on the circumference of the rotor being basically constant, while its inner limit positions are variable. It is advantageous for the actuator to be constructed as a pressure motor (hydraulic cylinder). It is expedient for each of the parallel-connected distribution sections in the control unit to be connected to a pressure source. The latter is connected via connection lines to one of the two pressure chambers. This distribution section is connected to a control element via adjusting connections. The invention can be used in boilers in power station and heating-power boilers and in all further industrial plants in which use is made of the waste heat from metallurgical, chemical and other thermal processes. <IMAGE>

Title: Device for determining the start of fuel injection in an internal combustion engine with an injection nozzle
Inventor: BAUMGAERTNER HERMANN DIPL ING
IPC: F02M65/00
Filed: 1981-08-08
Abstract: Determination of the start of fuel injection in an injection nozzle for an internal combustion engine is of particular importance for adjustment of the internal combustion engine. Hitherto known devices and methods do not possess sufficient accuracy. For increased accuracy with simplified construction and in order to increase the possible applications for a device for determining the start of fuel injection in an internal combustion engine with an injection nozzle, which has a nozzle needle (2), opening against the force of a spring (4) and counter to the direction of flow of the fuel, the movement of which needle generates a signal by means of a connected pressure sensor at the start of injection, the invention proposes that a pressure signal transmitter (8) be provided, which through an opening (7) in the nozzle holder (1) exerts a force in the direction of the nozzle needle (2) against the preloaded spring (4) and at the same time without effectively changing the spring preloading, absorbs a proportion of the contact pressure exerted by the preloaded spring (4) between adjusting plate (5) and nozzle holder (1) and at the start of injection generates the injection signal due to the rise of the contact pressure caused by the movement of the nozzle needle (2). The device can be used in already existing injection nozzles, the pressure signal transmitter (8) being formed by means of an existing fuel leakage connection of the nozzle holder (1). <IMAGE>

Title: Motor-vehicle seat which is designed such that it can be displaced longitudinally by means of running and guide rails arranged in pairs
Inventor: FUSSNEGGER WOLFGANG
IPC: B60N2/07
Filed: 1981-09-16
Abstract: In the case of a motor-vehicle seat which can be displaced longitudinally in running and guide rails and the displacing movement of which is transmitted via pinions, held on the end in a positionally fixed manner by a preferably motor-driven shaft, to a rack connected to the running rail, and the shaft is mounted in positionally fixed bearing plates, when forces act in the vehicle longitudinal direction on the motor-vehicle seat, they are introduced by a locking device in a manner bypassing the displacing device into the bearing plates. The locking device is composed of a lifting device with at least one spring-loaded locking bolt which during the longitudinal adjustment is at a distance from the running rail and after the longitudinal adjustment has taken place comes to bear resiliently against the running rail or, with an appropriate seat position, immediately engages in an associated opening of a row of holes connected to the running rail.

Title: Rotating cutting head of a roadway- or tunnel-driving machine
Inventor: HORST HEINZ ING GRAD
IPC: E21D9/11
Filed: 1981-10-09
Abstract: The invention relates to a cutting head of a light roadway- or tunnel-driving machine, in which cutting head the tool carriers are designed as arms pivotably mounted in a distributed manner over the periphery of the cutting head. The free ends of the arms are provided with roller drilling tools whose cutting planes run approximately tangentially to the orbital path of the tools. Since there is always the requirement, in particular in friable rock, for the supports to be placed as close to the working face as possible in order to provide protection against collapse and since, in addition, it is of advantage to also drive non-circular cross-sections, the object of the present invention is to develop the known cutting head accordingly. It is proposed to provide the pivot axes (12) of the tool-carrier arms (11) parallel to or virtually parallel to the axis of rotation of the cutting head. An area of the face is preferably allocated to each tool-carrier arm (11), the areas complementing one another in a congruent manner. The pivoting angle of each arm (11) is limited in such a way that the adjacent cutting paths (1 to 9) of the rollers (1 to 9) or at least of the outer rollers (3, 4 or 6, 7) of two adjacent arms (11) overlap. <IMAGE>
