Title: Indexing mechanism for calendar display - has auxiliary weighted drive coupled to second drive shaft for end of month correction
Inventor: MERKLE PAUL
IPC: G09D3/08
Filed: 1980-04-02
Abstract: The indexing mechanism has the correction for the end of the mouth achieved by an auxiliary weighted drive. The normal indexing is effected by an electric motor controlled by an electric or electronic 24 hour switch and coupled to a conversion gear. An intermediate shaft rotates once for each indexing step and cooperates with a rotary switch for subsequent disconnections of the electric motor. The auxiliary weighted drive acts on a second indexing shaft for supplementary indexing, with the drive weight suspended by a coil spring with its coil windings remaining in contact. The pre-tension of the spring is greater than the force of gravity of the drive weight.

Title: Speed regulator for gas compression engine - has speed sensor to control inlet butterfly over pneumatic actuator with mechanical override
Inventor: BERGMANN HORST
IPC: G05D13/34
Filed: 1980-04-03
Abstract: The automatic speed regulator for gas compression engines for commercial vehicle applications is designed to be inexpensive and of simple mechanical construction. Engine speed is sensed by an inductive pulse generator that uses a rotating notched disc that interacts with a coil. The coil controls a needle valve to regulate the flow of compressed air from a regulator to a pneumatic cylinder actuator. The actuator changes the position of a butterfly valve in the inlet manifold and so reduces fuel intake to vary the engine speed. The actuator body is coupled over a linkage to the accelerator pedal to provide mechanical override.

Patent DE-3107742-A1 (DE)
Title: Photo-electric detector circuit
Inventor: KATAYAMA TAKAO
IPC: H03K17/795
Filed: 1981-02-28
Abstract: Photo-electric detector circuits are known which have a pulse generator which serves to generate a pulse string which is forwarded to a light-radiating device in order to generate light pulses which are in turn received by a light reception device and converted into an electric signal. A detector circuit of this type is intended to be improved so that, if fluctuations occur in the light surrounding the optocoupler, no errors occur in the transmission. It is proposed that a release circuit is connected to the light reception device and the pulse generator in such a way that a signal occurs at the output of the release circuit in response to the electric signal only when the pulse generator has generated a pulse.

Patent DE-3109423-A1 (DE)
Title: Device for producing and controlling lingering sound
Inventor: FRANZMANN RAINER
IPC: G10H3/18
Filed: 1981-03-12
Abstract: The invention relates to an electronic device for producing and controlling lingering sound in electrically amplified musical instruments, in particular electric guitars and electric bases. The object of the invention is to eliminate disadvantages of the known electronic reverberation devices, for example chiefly the loss of sound presence caused by the temporal retardation and blurring of the transients of the sound signal, and the missing, simple controllability of various settings of lingering sound during playing. The achievement of this object provides that the electrical sound signal obtained by the sound pick-up is digitally coded and input into a preliminary memory, from which it is relayed into a main memory and read out with a time delay only if the original sound signal collapses abruptly due to damping. When the device according to the invention is applied in electric guitars and electric bases, it is preferable to be able to select three different settings by means of an operating lever during playing. First setting: no lingering sound. Second setting: lingering sound having a relatively steeply falling envelope. Third setting: lingering sound having a relatively slowly falling envelope.
Patent DE-3126873-A1 (DE)
Title: Loading tongs
Inventor: RINN JUERGEN DIPL ING
IPC: B23Q7/16
Filed: 1981-07-08
Abstract: In loading tongs, workpiece grippers (3, 4) are rotatably mounted on jaws (1, 2). A pivot drive (10) can be used to pivot the workpiece grippers (3, 4) through 180 DEG  from a position for vertically holding a disc-shaped workpiece. This means that parts resting on an end face can be removed from a pallet and pivoted through 90 DEG  so that they can be gripped by the chuck of a lathe with a horizontal spindle. It is moreover possible to pivot the parts through 180 DEG after one side has been machined, so that they can be gripped to permit machining of the other side. <IMAGE>

Title: Capacitive key
Inventor: AHLERS HORST DR SC TECHN
IPC: H03K17/975
Filed: 1981-08-19
Abstract: The invention relates to a capacitive key which, when operated, produces a change in capacitance and then a change in voltage and leads to the switching-over of an integrated trigger circuit. The capacitive key, in interaction with the trigger, is suitable for being configured in keyboards for input devices in data processing, in accounting and bookkeeping, control and measuring technology and in machine construction and motor vehicle construction. It is capable of converting mechanical input signals into digital output signals in a simple manner. According to the invention, two or more mutually insulated complex electrodes are located in a conductive key housing provided with earth potential, which electrodes, when operated, allow a maximum capacitance to arise which is limited by a conductive layer, for example colloidal carbon layer, which is located on a complex electrode and evens out the surface roughness, and allow a minimum capacitance to arise due to different layer sequences in the unoperated state. The change in capacitance leads to a change in voltage, the charge remaining the same, at the input of the trigger which switches over after a threshold voltage is reached. The uniform charge on the key constructed as a capacitor is achieved by a MIS clamping transistor. <IMAGE>

IPC: H01F27/245
Filed: 1981-09-28
Abstract: Recently, very thin metal sheets having very low remagnetisation losses and consisting of an amorphous material have been available for such iron cores. According to the invention, in each case a multiplicity of cut-to-size metal sheets are firmly assembled to form column-like, self-supporting, dimensionally stable sheet-metal stacks (1), and a complete iron core consisting of core limbs (3) and yokes (2) is assembled from such sheet-metal stacks (1), the sheet-metal stacks (1) interlocking at the node points between the core limbs (3) and the yokes (2) in the manner of brickwork. This construction of iron cores on the one hand permits highly economical manufacture of the same and in addition, because of the relatively low remagnetisation losses, leads to a lower loading for a required cooling device. <IMAGE>

Patent DE-3209402-A1 (DE)
Inventor: NEMETZ JOSEF
IPC: F16K5/20
Filed: 1982-03-16
Abstract: The stop or control valves used to interrupt or control fluids flowing through conduits, comprise a housing provided with inlets and outlets as well as an obturation member which can be in the shape of a cylindrical or frustoconical key, of a sphere or a flat slide valve. The obturation member comprises an inlet or recess, or it shows only a part of said geometrical shapes and is arranged so as to connect the inlet with the outlet in the open state and to block the path between the two passages in the closed state. These passages are provided with a waterproof seal, for instance a bellows seal, the effect of which is increased in case of an operating pressure increase. The known stop or control valves have the disadvantage that the seal has an unfavorable action on the liquid flow, that the prestress on the obturation member is partially low and that the seal is not free from wake space. Moreover, the bellows seal is pressure-sensitive and, consequently, can be damaged by too high pressures. In order to avoid those drawbacks an elastic sealing sleeve (5) provided with an arched section (6) is positioned in a part of the inlets and outlets; the convex part thereof is directed towards the axis of the flow conduit and bears on one side on the obturation member and on the other side on a shouldering, a stop or similar. The arched section (6) can bear, in case of an overpressure, on the wall of the housing (3).
