Patent DE-4233820-A1 (DE)
Title: Change speed gear for bicycle - has mechanism to reduce difference in speed ratio when changing from one chainwheel to other
Inventor: HANNIG CHRISTIAN
IPC: B62M25/02
Filed: 1992-10-08
Abstract: The change speed gear of the Derailleur type has sprockets mounted on the rear wheel and has two chainwheels actuated directly by the pedals. In the case where the numbers of teeth on the two chainwheels differ by more than ten there is a wide difference of speed ratio when changing from one chainwheel to the other. This difficulty is overcome by a mechanism which interconnects the cable, and which shifts the chain from one chainwheel to the other, and the cable which shifts the chain from one sprocket to another. USE/ADVANTAGE - Derailleur type change speed gear for a bicycle with a smaller change in speed ratio.
Patent DE-4238557-A1 (DE)
Inventor: LEUERER DIETRICH
IPC: B41F33/00
Filed: 1992-11-14
Abstract: In a process for setting the moisture content in an offset rotary machine, a signal for modifying the moisture content is to be generated before the scumming limit is reached. For that purpose, the densitometrically measured optical density on a control strip is compared with a number of variably selectable adjacent zones. When an adjustable measurement threshold is exceeded, the moisture content is modified as appropriate, thus preventing spoilage.

Inventor: HEIDL FRANZ
IPC: A47L9/24
Filed: 1993-02-08
Abstract: The invention relates to a vacuum cleaner hose with a coupling device for releasable connection to a hollow connection part, in particular to the suction pipe socket of a vacuum cleaner or a handle tube, in the case of which hose the coupling device comprises a hose sleeve (4), which is fixedly connected to the hose end (3) capable of being coupled and can be inserted into the connection part (1), and a coupling ring, which secures the hose sleeve (4) in the inserted state and is releasably held on the connection part (1).

Title: Method for calibrating the amplifier of a strain gauge on a crane
Inventor: KIMINKINEN HANNU
IPC: B66C15/00
Filed: 1993-03-03
Abstract: The invention relates to a method for calibrating the amplifier device (11, 12) of a strain gauge used for measuring the loading of a crane. A signal produced by the strain gauge and proportional to the load of the crane is fed into the amplifier device as input variables (13, 14) and the calibration is carried out, according to the invention, by software by means of a control unit (20) which uses a memory for recording data. During the calibration, in the case of an unloaded crane, a correction signal to be fed to the input (13, 14) of the amplifier device is determined in such a way that the desired zero level is attained at the output (19) of the amplifier and the signals which set the zero level of the output are recorded in a memory provided in the microcontroller (20), so that they can be used as operational variables for correcting the input signal. Subsequently, the crane is loaded with a known test load and the value of the gain of the amplifier device (11, 12) is determined in such a way that the desired level is attained at the output (19) of the amplifier device with a nominal load, and the gain value attained by this method is recorded in the memory, so that it can be used as an operational variable of the gain. <IMAGE>

Title: Method of repeatedly sealing used printer toner cartridges
Inventor: WIEGAND RUDOLF
IPC: G03G15/08
Filed: 1993-05-21
Abstract: The invention relates to a method of repeatedly sealing used printer toner cartridges, which are provided in the sealing region with a plastic ring, for example of PVC. The toner container of the toner cartridges of printers is sealed for transport by a plastic seal in order to prevent leakage of the toner. Before use of the toner cartridge in the printer, this seal has to be removed. Until now, these toner cartridges have been provided only for use just once. Repeated use of such cartridges is the aim. For this purpose, the invention provides that, after dismantling and cleaning the complete toner cartridge, a novel sealing strip (C), for example of polyester, is folded asymmetrically over a blade (H) and pushed into a slit between the opening of the toner container (A) and the receiving part for the magnetic roller of the cartridge to such an extent that it rests along the inner edges of the plastic ring (B). Part of the sealing strip (C) protrudes laterally out of the toner cartridge as a tab. Subsequently, an adhesive solvent is introduced between the bearing surfaces of the plastic ring (B) and the sealing strip (C), the said solvent dissolving only the material of the edges of the plastic ring (B) but not the material of the sealing strip (C). After a dwell time of a few minutes, the blade (H) is removed.

Title: Automatic disease evaluation from protein fraction data - obtd. from electrophoretic analysis of blood and comparison of characteristic parameters with those in intelligent tables
Inventor: YOKOGAWA HISAMITSU
IPC: G06Q50/22
Filed: 1993-09-13
Abstract: Automatic evaluation of disease type comprises deriving many characteristic parameters (CP) from analytical data on protein fractions obtd. by electrophoretic analysis of blood samples.  At least one intelligent table is constructed to represent the relationship between combinations of CP and each disease type.  A characteristic parameter pattern of a sample is generated by arranging CP according to a predetermined format and the pattern compared with the tables to indicate disease type. Pref. the CP pattern is first compared with a 'mask' pattern to exclude CP not used in the evaluation and the resulting logical prod. is compared with the corresp. prod. of an evaluation pattern. USE/ADVANTAGE - Used to diagnose diseases. Unlike known methods based on a logical tree, the process allows the normal values and/or evaluation conditions to be changed easily or extended.  It also allows more than one disease type to be detected from a single sample.
