Title: Device for generating photostimuli and for measuring the electroretinogram and the visual evoked cortical potential
Inventor: SEMBRITZKI OTTO
IPC: A61B5/0496
Filed: 1993-01-21
Abstract: Technical field: The electroretinogram (ERG) is used in medical diagnosis. The term refers to measurement of the difference in the electrical potential between the cornea of the eye and the temporal bone after stimulation of the eye with a flash of light. The shape and magnitude of the response amplitude allow conclusions about the function of the retina. Problem: The previously conventional devices have been too large, inflexible in terms of generation of the stimulus, unfriendly to the user, which leads to erroneous operation, they have not had a high performance and they do not meet international standards. Solution: A computer-controlled system for generating the photostimuli and for measuring the electrical responses. It controls the type of photostimuli, measures the ERGs of both eyes simultaneously and records the light intensity used. The curves are evaluated automatically. The measurement curves and the results of the evaluation are printed out on a printer with graphics capabilities. Possible applications: In ophthalmological practices, hospitals, operating theatres and in outpatient departments.
Patent DE-4302285-A1 (DE)
Inventor: SCHALLER HANS-LUDWIG
IPC: F27B3/04
Filed: 1993-01-25
Abstract: The invention relates to a steel works installation with a double-furnace plant and to a process for operating this installation. The process is intended for melting steel in an energy-saving manner without pollution of the environment. For this purpose, it is characterised by the following steps: one of the two furnaces is supplied with electric power for melting the charge present therein and the other is completely separated from the mains; the furnace which has been taken off from the power mains and tapped is charged with charge material; the furnace vessel is then sealed by a cover; subsequently the gas present in the vessel space is extracted above the column of charge; the flue gas from the furnace in electric operation is extracted from the furnace separated from the power mains via a connecting line provided between the two furnaces, the flue gas connection of the other furnace to the gas purification being broken during the extraction of the flue gas from the furnace separated from the power mains; and at the same time added air is taken up in the region of the cover of the furnace which is in electric operation. This double-furnace installation is designed according to the invention in a special manner. <IMAGE>

Patent DE-4309748-A1 (DE)
Title: Composition for combating perspiration odours
Inventor: PFEIFFER HEIKE
Filed: 1993-03-28
Abstract: Penetrating perspiration odour, especially unpleasant smelling sweaty feet, are a problem which mankind does not yet have entirely under control. Previous antiperspirants prevent sweat production by blocking the sweat glands, whereby the latter are, however, no longer able to fulfil their actual function, the control of body temperature. Medicines which reduce sweat gland activity influence the entire nervous system. Organic acids which are mainly responsible for the perspiration odour can be bound by zeolites, whereby bacteria do not decompose them and our nose is no longer able to perceive them. No health-damaging effect of zeolites is known. In addition, according to the proposals detailed below, a purely external use without skin contact takes place. It is simultaneously possible for alcohols which react with the acids to give esters with a fruity fragrance to be incorporated in these zeolites. It is also possible for other perfumes to be incorporated and released by adsorption of sweat. A triple deodorant effect is thus found. The powdered zeolite can, for example, be sewn into the sole of a shoe or processed with cellulose to give a paper-like intermediate layer for a sole.

Patent DE-4316167-A1 (DE)
Title: Device for site protection (grounds protection)
Inventor: NAGUSCHEWSKI THOMAS
IPC: G01S13/56
Filed: 1993-05-14
Abstract: A device is specified for site protection, which consists of a microwave barrier and an intelligent evaluation device. The evaluation device contains an evaluation processor which classifies, by means of a neuronal network, signals of the microwave barrier which initially trigger an alarm as being tolerable from then on when it is fed from outside with a "harmless" signal. The latter may be the result of an investigation of the event which in each case triggered the alarm, using an automatically triggered video recording. When the device is used in particular in conjunction with a fence, a reduction in the number of false alarms (spurious alarms) by about 90% is achieved by training the evaluation processor in this way. <IMAGE>

Title: Throttle valve controller for internal combustion engine - has flap position sensor characterised by steeper output voltage gradient over range of idling speeds
Inventor: SASAKI YASUSHI
IPC: F02D11/10
Filed: 1993-09-17
Abstract: The throttle flap (1) is rotated about its axis (3) by a motor (6) with an electromagnetic clutch (9) jointly operated by a control unit (4) in response to a set-point input (5) and signals (25,26) from position sensors (16,17) of the flap and accelerator pedal (14) respectively. The flap sensor has a different output voltage characteristic for a range of positions covering normal idling speed and fast idling, where resolution is enhanced by a steeper characteristic gradient than that associated with higher speeds. ADVANTAGE - Simple structure affords sufficient control of throttle valve in partially-open range.

Title: Method of holding down of crossing point tip in rail road
Inventor: GRUNWALD DIETER
IPC: E01B7/14
Filed: 1993-12-01
Abstract: The tip is held down in the rest position, and is released before changing over. An electromagnet can be used to hold the tip down, and there can be a slide plate under the two rails (2,3) between which the tip moves. The plate can be recessed at the magnet (6), while in the released state there is only a small gap of preferably less than 1 mm between the magnet and the tip. The magnet can be wider than the latter, and can extend for the full length of tip movement. Alternatively, there can be two electromagnets alongside each other in the direction of tip movement, and which are energised dependent on the tip position.

Patent DE-4343627-A1 (DE)
Inventor: DEPENBROCK MANFRED PROF DR ING
IPC: H02P21/34
Filed: 1993-12-21
Abstract: A method is proposed for regulating the flux magnitude and torque in an induction machine which is fed via a converter, a model stator current space vector (@sm), a model stator flux space vector (@ mu m), a model actual torque value (Mdm) and a model stator voltage space vector (@sm) being formed. A flux magnitude test signal ( DELTA psi  mu ref) is superimposed on a predetermined required flux magnitude value (@ mu ref). The difference torque (Md-Mdm) between the actual torque value (Md) and the model actual torque value (Mdm) is calculated from the current difference (@s-@sm) between the stator current space vector (@s) and the model stator current space vector (ism) and the model stator flux space vector (@ mu m). A signal for adjusting the model rotor resistance (Rrm) is formed by multiplication of this difference torque (Md-Mdm) by the flux magnitude test signal ( DELTA  psi  mu ref). This model rotor resistance (Rrm) is adjusted via regulation, which acts essentially integrally, until it corresponds with the rotor resistance (Rr). <IMAGE>
