Title: Single-track vehicle with lateral support wheels
Inventor: LAMMEL ERNST DIPL ING
IPC: B62H1/12
Filed: 1981-02-21
Abstract: In the patent application "single-track vehicle with lateral support wheels", the design of support wheel pairs is described and illustrated in an outlined drawing, the use of which wheel pairs is made superfluous in single-track vehicles by the driver providing leg support when the vehicle is stationary and travelling slowly, and the usual internal inclination of the vehicle when going around a bend is maintained when travelling quickly by switching off the support effect. This is achieved in that the support wheel transverse bracing has arcuate tracks on which rollers, gearwheels or sliding elements are supported, roll or slide and which are connected to the vehicle running gear in a secure or elastic fashion or articulated about the transverse axle. This support wheel design can be used for all single-track vehicles and gives rise to great advantages with respect to energy, space and weight saving in particular in passenger vehicles with a row of seats arranged one behind the other. <IMAGE>
Patent DE-3110922-A1 (DE)
Title: Cavitation power station
Inventor: WENZ DIETER
IPC: F03G6/00
Filed: 1981-03-20
Abstract: The cavitation power station operates according to the principle of a low-temperature steam engine using the vacuum method and operating temperatures below 100 DEG C. The vacuum container (1) is mounted rigidly or movably. Its steam (2) and condensed water chamber (3) is fitted with a piping network (4) which is alternately charged with hot or cold water. The hot water originates, e.g., from solar collectors (5). After heating the condensed water in the condensed water chamber, said condensed water evaporates after opening of the sliding closure (6) and flows into the steam chamber, where the steam pressure moves one or more pistons (7) in the steam chamber wall. The piston thrust force is relayed via a force-transmitting system (8) to the generator (9). Subsequently, the piping network is charged with cold water, whereupon the water vapour condenses and runs back into the condensed water chamber. Thereafter, the pistons are pushed back, e.g. by means of a hydraulic device (10), the slide is closed and the piping network is recharged with hot water, and so on. The cavitation power station can be used to generate electrical energy for small-scale and large-scale consumption. <IMAGE>

Patent DE-3117472-A1 (DE)
Title: Torque-limiting clutch
Inventor: JAKOB LUDWIG ING GRAD
IPC: F16D7/08
Filed: 1981-05-02
Abstract: The invention describes a spring-loaded positive clutch for limiting the torque between two drive components. In order to guarantee rotary play-free functioning with little outlay and few components, spring-loaded shaped parts are pressed into matching recesses or cups through which the join between the two clutch halves runs. Given appropriate design of the recesses, the shaped parts are centered in the latter by the spring force and hence fix the relative position of the two clutch halves in such a way that there is no play.

Title: Method for connecting a subscriber device
Inventor: PARRAS KARL-HEINZ DIPL ING
IPC: H04M11/08
Filed: 1981-05-05
Abstract: If a subscriber station is intended to be connected to a transmission line, the input resistance of a subscriber device disposed in the subscriber station is intended to assume a pre-defined resistance value corresponding to the switching state of a connection unit. If data which are added as frequency signal components to a loop current are transmitted via a transmission line, an operating voltage can be obtained for the subscriber device by separating the signal components and the DC components. The transmitted data signals must also be simultaneously separated in the subscriber device in forward and return directions. If the amplitude of the AC voltage component on the telephone line is measured and thence a control voltage for a voltage-controlled voltage source is derived from a reference voltage and from the output voltage of a signal converter disposed in the subscriber device, a voltage can be set via a voltage-controlled voltage source in such a way that the input resistance of the subscriber device is set according to the required input resistance values.

Title: Device for controlling equipment in mining
Inventor: RUDAT RAINER
IPC: G08C23/04
Filed: 1981-06-06
Abstract: In mining, equipment is pneumatically operated via an intrinsically safe solenoid valve. The solenoid valve is controlled by an infrared remote control receiver. The infrared remote control receiver receives signals from an infrared remote control transmitter on a number of channels. The risk of operating errors, which can arise due to the fact that the housing rests with its operating key on a base and the operating key is unintentionally pressed down, is avoided by advantageous arrangement of operating keys on opposite sides on the housing of the infrared remote control receiver. In one embodiment, a pulse width control, also on a number of channels, enables the pneumatic flow through the solenoid valve to be continuously adjusted.

Title: Arrangement for controlling the air-fuel ratio of an internal combustion engine
Inventor: KURIHARA TOSHIRO
IPC: F02D41/14
Filed: 1981-07-07
Abstract: An arrangement for controlling the air-fuel ratio of a carburettor of an internal combustion engine has an intake port, an exhaust port, a throttle valve, a detector for determining the concentration of one constituent of the exhaust gases, an open-close solenoid valve for correcting the air-fuel ratio of the air-fuel mixture, which is fed by an air-fuel mixture feed device, and an electronic control device. The electronic control device contains an analysing circuit for comparing the output signal of the detector with a stoichiometric reference signal for the drive of the open-close solenoid valve for adjusting the air-fuel ratio to a value approximating to the stoichiometric air-fuel ratio. An acceleration sensor and an engine temperature sensor are provided. A correcting circuit allows the electronic control device not to respond to the detector if the engine temperature sensor is working with the engine cold and to respond to the output signal of the acceleration sensor, as a result of which the open-close solenoid valve operates as a function of the output signal of the acceleration sensor. <IMAGE>

Title: Circuit arrangement for generating pulse strings which are reliable in signal terms
Inventor: GRONEMEYER MICHAEL DIPL ING
IPC: H03K5/135
Filed: 1981-07-13
Abstract: In order to generate pulse strings which are reliable in signal terms for reliable switching mechanisms, for example in railway signalling systems, a crystal generator (G) is provided whose clock pulses increment a multi-stage shift register (SR) at a repetition rate (fG) after a single start-up process. The delay period (TZ) of a delay component (Z) is defined in such a way that the shift register (SR) is restarted automatically for a further cycle only when a duration of a single cycle of the shift register (SR) pre-defined by the clock frequency (fG) of the crystal generator (G) and the step number (n) of the shift register (SR) is maintained. A type of dynamic self-holding circuit is thus produced during correct operation. The clock signals required for the reliable switching mechanism are obtained from the outputs (Q1 to Qn) of the individual stages (SR1 to SRn) of the shift register (SR). <IMAGE>

Title: Force measuring device
Inventor: KLAEMT JOACHIM ING GRAD
IPC: G01L1/22
Filed: 1981-12-09
Abstract: A force measuring device having two mutually mobile parts is described, of which one part is a basic body that is provided with a freely projecting bending element on which strain gauges are mounted, and of which the other part is a force transmitting member which engages with the bending element through a central bore in the basic body, and having an overload safety device for limiting the paths of the force transmitting member with respect to the basic body. In such a force measuring device, there is provided for overload protection at least one fitting pin, which is arranged fixed on one of the two mutually mobile parts and engages with play in the other part. Advantages of the invention are that this type of overload protection can be realised very simply with virtually any desired accuracy, since the bore diameter and the radii of the fitting pin can be very exactly dimensioned. Because of its simple design, this overload protection is suitable, in particular, for force measuring devices which are oil-encapsulated. The accuracy of the overload protection provides advantages, in particular, in force measuring devices in which only very small measurement paths (of the order of magnitude of between 0.02 and 0.06 mm) are covered.

Title: Stone-splitting tool
Inventor: PORSFELD FRIEDHELM
IPC: B25D17/08
Filed: 1981-05-18
Abstract: Stone-splitting tool with a tool holder in which several individual splitting wedges (34-42) are arranged in a row and in such a way as to be movable relative to one another, the individual splitting wedges (34-42) each being displaceably mounted in a cylinder space (46, 46',...54, 54') filled with an incompressible medium and the cylinder spaces being fluidically connected to one another. For the purpose of spontaneous adaptation of the individual splitting wedges (34-42) to different surface structures or heights of the stones to be split, the cylinder spaces are closed off on the side remote from the splitting wedges by a cylinder head (58), on whose side facing the cylinder spaces a groove (56) is arranged in order to produce a virtually undamped fluid connection between the individual cylinder spaces (46, 46',...54, 54'). To increase the splitting intensity, the reciprocating displacement of the individual splitting wedges (34-42) is in each case limited by a mechanical stop which is designed in the form of a piston-guide and end plate (30). The piston rods of hydraulic pistons which can be displaced in a reciprocating manner in the cylinder spaces, which piston rods are connected to the individual splitting wedges (34-42), are passed through the plate (30) in a sealing manner in such a way that they interact with pistons (64, 64',...72, 72') on the one hand, which are allocated to the individual splitting wedges (34-42), and with projections (thrust plate 74) on the other hand, arranged on the individual splitting wedges (34-42), in order to limit the travel of the said projections.   <IMAGE>

Title: Method and device for turning sheets in multicolour sheet-fed rotary printing machines
Inventor: KUEHN WILFRIED DIPL ING
IPC: B41F21/10
Filed: 1982-01-20
Abstract: The invention relates to turning sheets in multicolour sheet-fed rotary printing machines for the purpose of printing the back of the sheet. The aim of the invention is to guarantee in-register two-sided printing at high operating speeds whilst maintaining minimum loss of printing areas. The object consists in gripping the trailing edge of the sheet, during the movement phase of the greatest paper pull during the sheet transfer, by a suction strip extending virtually without gaps over the entire sheet width. According to the invention this is achieved in that the trailing edge of the sheet is gripped on the impression cylinder running in front of it by a suction strip formed by the first suction system and a second suction system and extending in a straight line over the entire sheet width and is swivelled in the direction of the interior of the cylinder, the second suction system releasing the sheet halfway towards delivery to the gripper system and remaining stationary and the sheet being conveyed further and transferred to the gripper system solely by the first suction system.

Title: Spectacle hinge
IPC: G02C5/22
Filed: 1982-01-21
Abstract: The invention relates to a spectacle hinge for pivotably mounting a bow on a spectacle frame. The hinge consists of a U-shaped first hinge part, in particular fixed to the bow, and a second hinge part which engages between the limbs of the first hinge part and is mounted, in particular, on the frame, as well as a mounting bolt which passes through the hinge parts as pivot axis. According to the invention, it is provided that at least between one limb of the first hinge part and the second hinge part an insert is arranged which is connected to the limb securely with respect to rotation, and that a cam arranged on the second hinge part securely with respect to rotation latches resiliently with the insert in the open and closed position of the bow. As a result, the open position of the bow is stably determined without it being necessary to provide external stop means for this purpose, as a result of which a larger freedom of configuration is provided in the design of spectacle frames. A resilient construction of the insert at the latch point permits elastic overstretching of the opened bow, and thus a defined head pressure of the spectacles.
