Title: Cardiogram marking device with selector switch - controlling connection of pen recorder voltage source prior to, or during, recording paper transport
Inventor: STANGL FLORIAN
IPC: G01D9/28
Filed: 1979-03-27
Abstract: For the cardiogram evaluation, the amplifiers must have a standard frequency response in the range of 0.05 to 100 Hz. The cardiogram marking device comprises a selector switch for triggering, responding to the conditions to be recorded. In accordance with the switch position, a writing recorder, or an additional writing recorder, is coupled to a voltage source, affecting the characteristic marking, during transport of the recording paper web. The voltage source is pref. of the negative polarised 1 m V type, in relation to the writing recorder deflection. This source may be coupled to a pulse gnerator, via a switch mechanically connected to the selector switch. The additional writing recorder may be mounted as an edge marker, coupled to rectangular mark generator, via the switch.

Title: Medicaments for treatment of arthrosis - consisting of a sterile aq. soln. of cysteine for intra-articular injection
Inventor: HEMPEL BERND DR
IPC: A61K9/00
Filed: 1979-04-04
Abstract: New medicaments for combating arthroses contain cysteine as active ingredient, and are in the form of a sterile aqueous soln. for intra-articular injection. Cysteine inhibits the activity of collagenase and thus prevents degradation of collagen fibres in joint cartilage. When administered by intra-articular injection, cysteine can considerably retard the advance of arthrosis. The antiarthritic activity of cysteine was determined in hens in which arthrosis had been induced by intra-articular injection of 0.25mg monoiodoacetate in the left knee joint. Test prepn. (cysteine in 0.1ml 0.9% saline) was administered by intra-articular injection on day 2. X-rays of the joint were taken at the beginning of the study and after 6, 8, 10, 12 and 14 weeks, and the width of the gap in the joint was measured. In control animals treated with saline only, the width of the gap had decreased by ca 50% after 14 weeks. In animals treated with 0.01 mg cysteine, the width of the gap had decreased by ca 35% after 14 weeks, and in animals treated with 0.1 mg cysteine the decrease was only ca 17%.

Title: Electrostatic copier with copy remover - has brush and filtered vacuum drum cleaner and air blast turned to remove copy from drum
Inventor: TSUDA HIROSHI
IPC: G03G21/10
Filed: 1979-04-18
Abstract: An electrostatic copier develops a toner on a drum and then transfers the image to copy paper. A vacuum and brush cleaner mechanism is used to remove residual toner from the drum after transfer and the output blast of the vacuum appts. is turned back towards the drum and used to separate the copy paper from the drum after picture transfer. A fan (21) produces the air stream to draw the toner residue off the drum into a filter (22) and the clean air is turned back by channeling to the point where the copy paper is lifted from the drum (at 10).

Title: AC tachometer generator with linearising circuit - has lineariser measurement diode bias current for increased null linearity
Inventor: FRENK HELMUTH DR
IPC: G01P3/46
Filed: 1979-08-09
Abstract: An a.c. tachometer generator with a rectified output voltage and a linearising circuit (52) in one output lead is improved in linearity in the null region. A constant current source is connected between the power supply (53) for the linearising circuit (52) and the lead of the tachometer generator no contg. the linearising circuit. The constant current circuit consists pref. of a transistor (57) with an emitter resistor (58) and a base voltage potential divider (59,60). The constant current circuit supplies an approximately constant continuous bias current which flows through the measurement diode but not in the external measurement resistor (26). The measurement diode voltage is used for linearisation purposes and can be in error owing to extremely small offset voltages in the amplifier input in the null region if no bias current is used.

Title: Steplessly-adjusting hydraulic transmission - has valve throttling fluid flow causing pump housing to rotate and transmit drive
Inventor: WEITZEL MICHAEL
IPC: F16D31/04
Filed: 1980-01-11
Abstract: The steplessly-adjustable hydraulic transmission is for automotive and industrial use, and it includes a plunger- or gear-type pump. This is coupled both to the driving and driven shafts, but is only caused to transmit the power by the fluid itself. A central valve regulates the fluid flow and thus the velocity ratio, and as it throttles the fluid the pump housing is caused to rotate and thus to drive the driven shaft. The valve can be actuated by a sliding block.

Title: IC engine knock detection system - has variable amplifier between knock sensor and demodulator controlled by drive rotation rate
Inventor: ROHDE SIEGFRIED DR ING
IPC: G01L23/22
Filed: 1980-03-18

This is connected to a comparator via a background signal path and a knock signal path, each including a low pass filter (5,9) and a signal shifting stage.The output of the knock sensor is fed to the demodulator via an amplifier with a variable amplification factor dependent on the rate of rotation of the drive. Pref. a high pass filter lies between the knock sensor and the amplifier and a second amplifier is inserted between the low pass filter and the second shifting stage in the background signal path between the demodulator and the comparator. The latter pref. gives a digital output indicating the presence, or absence of engine knock.

Title: Device for mechanically mounting pressure caps on bottles or the like
Inventor: SCHOTT HELMUT
IPC: B67B1/04
Filed: 1981-05-09
Abstract: A device for mechanically mounting pressure caps, plugs, dispensers or the like on bottles, glasses and similar receptacles is proposed. In this process, the caps (11) are taken hold of and are pressed into the mouth of a bottle (14) using one and the same pressing-in tool (16). The pressing-in tool (16) is mounted in a reciprocating manner in an oscillating lever (17) and can therefore be pivoted from a receiving position into a mounting and pressing-in position. The caps (11) are fed via feeding paths (12) of a cap reception device (13), one cap (11) being moved up from the feeding path (12) into the cap reception device (13) each time the entire oscillating movement of the oscillating lever (17) is actuated. There is therefore sufficient time available for a cap (11) to move up into the cap reception device (13), so that a cap (11) is reliably and smoothly received by the pressing-in tool (16) and the mounting and pressing of a cap (11) into the mouth of a bottle (14) are ensured. <IMAGE>
