Title: Indicating and registering circuitry - has monostable multivibrator connected to power switching stage supplied by non-stabilised working voltage
Inventor: KNAUFF UWE DR ING
IPC: G01R23/06
Filed: 1980-11-05
Abstract: Electrical values used, e.g. in engine compensators, as well as revolutions and speed are registered and indicated esp. for journey recorders. A frequency-to-voltage converter is controlled by a pulse generator. A servo system operates according to the principle of automatic input voltage or current compensation using a servo amplifier, servo motor and a potentiometer. The preamplifier of a commercially-available initiator circuit (1) has positive feedback via a resistor (15). A threshold value switch is coupled to the input of a monostable multivibrator via a differential stage. The multivibrator is supplied from an internal constant voltage source. It is joined to an RC element (22,23) by switching in a further internal threshold value switch.

Title: Marking system for plates on magnetic tape - using memory and detector, marking during brief movement of tape, esp. for detection
Inventor: FISCHER WOLFGANG
IPC: G11B27/32
Filed: 1980-12-06
Abstract: The marking system has a memory (10) and a detector. The detector detects the presence of markers on the tape and controls tape movement accordingly (either forwards or reverse). During the brief tape motion (forwards or reverse) occurring after a marker has been detected, the contents of the memory are recorded onto the tape. The opposite process occurs when reading the tape. The system is intended for dictation. The operator is equipped with a small keyboard (12) for operating (13) marking (14) and spacing (15).

Title: Device for pressing metal pins into receiving bores of a plastic baseplate
Inventor: ZEISER MANFRED P DR
IPC: A61C13/00
Filed: 1981-03-07
Abstract: In a device for pressing metal pins into receiving bores of a plastic baseplate for a denture model, in which a heater plate is arranged stationary at a distance from and parallel to a support disc for the baseplate, which support disc is displaceable, by means of an actuating element, towards the heater plate which heats the metal pins inserted into the baseplate by contact with their exposed end faces, the aim is for a manually operated bow, in its operating position, to shield the space between the heater plate and the support disc in the manner of a frame, it being only possible to initiate the actuation operation of the support disc when the bow is in this operating position. The risk of injury, for example by trapping a finger between the support disc and the heater plate, is thus effectively avoided.

Title: Measuring tape (tape measure, tape rule) with a fitting for internal (inside) and external (outside) measurement
Inventor: MEYWALD GUENTER
IPC: G01B3/10
Filed: 1981-07-29
Abstract: A measuring tape having a tape strip (1) provided with a scale (graduation) (2) has a fitting (6), which is arranged at the start of said strip, and a pulling handle (12). The fitting (6) has a first stop (9) for internal measurement and a second stop (10) for external measurement. In order to be able to use the measuring tape in an equally favourable way for internal and external measurement, the scale (2), which starts with the zero mark (3) at the start of the tape strip (1), is arranged at the end of the fitting (6) on the side of the pulling handle and also in the plane (11) which is defined by the first stop (9) for internal measurement and extends at right angles to the tape strip (1). The second stop (10), which is intended for external measurement, is provided on the stop (6) in a second plane which extends at a distance parallel to the first plane. In the case of external measurement, the second stop (10) on the fitting (6) can be varied in the plane (11) extending at right angles to the zero mark (3) of the tape strip (1), for example can be rotated or displaced. <IMAGE>
Patent DE-3136171-A1 (DE)
Title: Device for measuring forces, in particular weights
Inventor: ZUMBRUNN WERNER
IPC: G01G7/04
Filed: 1981-09-12
Abstract: The device for measuring forces, specifically a balance (pair of scales), has a support (1) and an electrodynamic force compensator (21) having a magnet (23), mounted rigidly on the support (1), and a coil (29), which can be moved with respect to said magnet, is provided with two windings (33 or 35), and is connected to the balance pan. During weighing, the two windings (33, 35) are fed a direct current whose magnitude has a linear relationship to the weight to be determined. Furthermore, an alternating current formed from rectangular pulses is fed to the two windings (33, 35). In this arrangement, the pulses are controlled as a function of the magnitude of the direct current in such a way that the heat output generated in the windings (33, 35) is independent of the magnitude of the direct current. The windings (33, 35) are, furthermore, constructed and connected in such a way that the alternating current generates virtually no magnetic field. In this way, the heat output in the coil windings (33, 35) can be held constant without thereby giving rise to deviations in linearity or other undesired side effects. <IMAGE>
Patent DE-3137317-A1 (DE)
Title: Vehicle operated by muscle power
Inventor: RUESS HARDY
IPC: B62M1/20
Filed: 1981-09-19
Abstract: Between the two frame halves of the bicycle frame (1) designed as a double frame, in the vehicle central plane a seat rocker (11) is guided by its swivel bearing (12) such that it can swivel on the vehicle frame and is connected by a coupling link (17) to a driving member (18). This driving member is mounted by means of two coaxial pivot bearings (19) on the free end of a two-part driving rocker (21) which can be swivelled around rocker bearings (22). This driving member has two lateral double cranks with in each case an outer pedal crank (26) and an inner rocker crank (28) which, coupled to the seat rocker (11) and driving rocker (21), forms a four-bar chain. The pedals (27) are guided by this means on an oblique, elongate revolving path (44). The driving forces which are exerted alternately on the pedals and the saddle (13) can therefore be brought into effect over a large path. With one crank revolution, due to improved translation of the power a larger distance is covered than hitherto. Since the gear mechanism, despite the improved drive, has only three moving parts (11, 28, 18 and 21), guide play and vehicle weight are low which, in turn, acts in favour of increasing the prevailing speed and the driving powers which can be achieved. The angle between rocker crank (28) and pedal crank (26) can be designed such that it can be changed to adapt to body size and seat position, and also both pedal cranks (26) can form an intermediate angle in order to offset the driving angles of the two pedal cranks with respect to one another and, as a result, to extend the entire driving angle available to over at least 360 DEG . <IMAGE>
Patent DE-3137555-A1 (DE)
Title: Combined board
Inventor: MUELLER HEINZ-PETER DIPL ING
IPC: A47B97/04
Filed: 1981-09-22
Abstract: Boards which can be written on or can be provided with drawings, display sheets etc. in demonstration and instruction rooms are often designed in such a way that two partial board surfaces are displaceable in parallel planes. By pulling forwards or pivoting the one partial surface, which is guided, for example, in knee joints or in another design can be pivoted about a horizontal axle, into the plane of the front board and subsequent releasable or permanent fixing, both partial surfaces can be combined to form a continuous large surface. This surface is still (in total) displaceable and is particularly suitable for drawings due to the large size. Due to the type of fixing, for example clamps or screws, a temporary combination, which is possible for example during the lesson, as well as a longer-term conversion, for example necessary for a school year, can be carried out depending on educational requirements.
