Patent DE-2635762-A1 (DE)
Title: Electromagnetic force measurement system - determines static forces in relays and switches using pressure cell and control amplifier system
Inventor: CORDT WERNER
IPC: G01L5/00
Filed: 1976-08-09
Abstract: An electromagnetic force measurement device consists of a pressure cell and a control amplifier for static measurement of forces occurring on relay contacts, switch springs etc., is designed for measurement without operation of the relay or switch. It is also designed for a larger measurement range than previously used devices. The measurement head of the capsule is attached to the centre plate of a three plate capacitor which moves at right angles to the outer plates. The capacitor is connected in a bridge circuit with two resistors. An alternating voltage source and a differential amplifier are connected to opposite diagonals of the bridge. The amplifier output is processed to give an indication of force and provide the capsule operating power.

Title: Electromagnet for extracting foreign body from eye or tissue - uses coil supplied with short current pulses for controlled withdrawal of body
Inventor: LANDWEHR GOTTFRIED PROF DIPL P
IPC: A61B17/52
Filed: 1976-09-28
Abstract: Appts. for controlled extraction of magnetisable foreign bodies partic. from eyes and tissues comprises an electromagnet of which the coil is supplied with short current pulses of which the length and intensity may be adjusted. A series of pulses may be used, on which d. c. is superimposed. The coil pref. consists of an air-core coil surrounded by a steel casing, includes lamellar means for concentrating magnetic flux, and minimises eddy current losses by selection of the material for magnetic flux concn. By using short current pulses, movement of a foreign body in the eye can be split up into short sections. If the lens of the eye is not damaged, extraction can be monitored optically.

Title: Determn. of low resistance points on human body - uses AC supply fed via potential divider including skin, to filter and rectifier and voltage-frequency converter driving loudspeaker
Inventor: SCHULZ AXEL ING GRAD
IPC: A61H39/02
Filed: 1976-10-11
Abstract: The points of low ohmic resistance on the body are those useful for acupuncture. DC measuring apparatus is liable to disturbance due to mains pick-up. To avoid this problem the equipment uses an AC generator of at least 60Hz, which feeds a potential divider, one of whose elements is the human skin resistance. The output of the potential divider is fed through a filter and a rectifier to a voltage-frequency converter and thence to a loudspeaker. The output of the rectifier is preferably fed to the voltage-frequency converter only when it reaches a significant level; the trigger circuit that provides for this is set for the individual patient with the aid of a preliminary test, during which a meter shows the range of resistances to be expected from him.

Title: UV polymerisation of acrylic ester dental compsn. - contg. benzoin deriv. as sensitiser and organic phosphite activator
Inventor: SCHMITT WERNER DIPL CHEM DR
IPC: C08F2/50
Filed: 1976-10-14
Abstract: UV light polymerisable materials are based on compsns. contg. mono- and/or poly-functional (meth)acrylic esters, benzoin or a benzoin deriv. as UV-initiator and opt. stabilisers and fillers. They also contain 0.1-20 (pref. 0.1-2 and partic. 0.2-1) wt. % of an aliphatic, aromatic or mixed aliphatic-aromatic phosphite on acrylic ester as activator. Used in dentistry as tooth cavity fillings or coating materials for sealing tooth surfaces. In an example, organic phosphites have been widely used as stabilisers to improve storage stability and colour of polymerisable materials. It has now been unexpectedly found that the benzoin-initiated UV polymerisation of acrylic esters is accelerated by such additives. Addn of 5 wt. % trisnonylphenylphosphite to 2,2-bis- -p-(gamma-hydroxypropoxy)-pheyl propane di-methacrylate contg. 200 ppm each of p-methoxyphenol and ionol as stabilisers shortened the setting time on addn. of 2 wt. % benzoin Me ether from 22 to 11 s.

Filed: 1977-05-20
Abstract: The display in a diffusion type electrochromic display device is turned off with high response by applying an A.C. input voltage having a frequency of one to ten times as high as the cut-off frequency. The diffusion type electrochromic display device is an EC display device which uses an EC composition consisting of an EC compound coloring in a reduced state and a solvent in which the solubility of the compound to the solvent is 10-2 mol/(100 g solvent) or more in a reduced state and 10-1 mol/(100 g solvent) or more in an oxidized state. The cut-off frequency is a critical frequency at a freqency higher than which the oxidization or reduction of the EC compound cannot follow the change in the input voltage, which is normally 20 to 50 Hz.

Title: Computer aided microwave filter tuning - calculating actual component values from measured functions and comparing with required values
Inventor: GUENTHER ALFHART DIPL PHYS
IPC: H03H3/013
Filed: 1977-09-29
Abstract: Filter two-pole and/or four-pole functions are measured at different frequencies, and the measured functions are used as adjustment criteria using a computer. Measured values of the selected filter function are applied to the computer which determines the faulty filter circuit component values and their corrections. Then individual components re consecutively adjusted, with the computer simulating the filter function as it should be after this component adjustment, and after other earlier adjustments. This is done by reducing the difference between the actual function value and its nominal value to within a specified limit.
