Title: Measuring device for the optoelectric evaluation of test paper strips
Inventor: BLUEMEL REINHARD
IPC: G01N21/86
Filed: 1981-03-26
Abstract: In a measuring device for the optoelectronic evaluation of test paper strips, e.g. for determining blood sugar, a holder is proposed for the strips which is improved with respect to simple production and installation and with respect to user-friendly design both as to use of the measuring device and as to cleaning. Said holder comprises a cover flap which is pivotably supported on the housing and can be pivoted between an open position, in which the cover flap rests, in common with the housing underside, on a support, and a closed position in which the cover flap rests on the housing top side. Provided on the inside of the cover flap is a spring which presses the retaining piece for the test paper strip away from the cover flap. A hold-down device rests on the retaining piece and contains a permanent magnet which is attracted by a plate of steel sheet seated in the cover flap. A channel for accommodating the test paper strip is formed by the opposite surfaces of the retaining piece and the hold-down device. <IMAGE>

Title: Processing spool for holding a photographic film strip in spiral form
Inventor: PETSCHING HELMUT
IPC: G03D13/14
Filed: 1981-04-03
Abstract: In the case of a processing spool (10) for holding a photographic film strip, the aim is for the strip to be held in the form of a spiral which is wound around the axial spool core (11) and in which the individual film turns are held at a defined radial spacing from one another. This purpose is served by guide ribs (26, 27), which in each case form on the inside of the spool flange (12) joined to the spool core (11) a continuous spiral groove (26) for inserting the film strip. So that there are no processing defects, the guide ribs (26, 27) are constructed - apart from punctiform supporting parts (32) - on inserts (23) which can be plugged if required into cutouts (24) in the spool flanges (12), starting from the outside (22) of the flange, and the punctiform support parts (32) are seated on webs (18) which remain between the cutouts (24) of the spool flanges (12) after removal of the inserts (23). <IMAGE>

Title: Mechanism for speed alteration
Inventor: NEWTON ALAN ROBERT
IPC: F16H1/32
Filed: 1981-12-22
Abstract: The mechanism for speed alteration, in particular for speed reduction, is of simple construction and makes it easy to provide different speed reduction ratios, in particular a high speed reduction ratio. The mechanism comprises an internal gear (30) and an external gear (38), which are in mutual engagement in one plane, and a nonrotatable sliding part (36). In alternative embodiments, either the internal gear or the external annular gear can be rotatable. In one embodiment, the internal gear is driven by the input shaft (22) under the control of the sliding part (36) in order to ensure that it is in engagement at its periphery with the annular gear, the annular gear thereby being driven. The internal gear runs on the annular gear but is held in the nonrotatable condition by the sliding part. The reduction ratio is a function of the number of external teeth of the internal gear in comparison with the number of internal teeth of the annular gear. The greater the number of teeth, the higher is the reduction ratio. In another illustrative embodiment, the speed reducer takes the form of a hand-operated winch. <IMAGE>

Patent DE-3247855-A1 (DE)
Title: Force conversion via oscillating beams
Inventor: SCHNOCK JOHANNES
IPC: F15B11/00
Filed: 1982-12-23
Abstract: The present patent application relates to the sector of hydraulics and pneumatics. The essence is an oscillating beam having, at both ends, pistons which are under pressure either hydraulically or pneumatically, a roller wheel being mounted centrally as an antipole on the other side. As a result of the rotation of the wheel to one side, one side of the oscillating beam becomes longer and the other shorter. After the conversion via the oscillating beam, the force, which is present as secondary energy, can be utilised directly as such or can be converted again into a mechanical force via a hydraulic motor. This ensures that the piston on the long side is extended as far as the limit stop and simultaneously retracts the piston on the short side. As a result of the rotation of the wheel in the other direction, the operation is repeated in reverse order.
