Inventor: JANSEN-HERFELD ROETTGER DIPL I
IPC: B28D1/06
Filed: 1988-08-18

Patent DE-3841446-A1 (DE)
Title: Clasps for partial dentures and profiles for producing them
IPC: A61C13/267
Filed: 1988-12-09
Abstract: The conventional clasp constructions in which a retention arm is supported against a partial collar on the opposite side, are unsuitable for combined tooth restoration. Whereas telescopic crowns are removed in an axial direction, clasps connected to the frame in the molar region must be taken off more rotatingly, and this leads to damage to the periodontal tissue. In the clasps according to the invention this disadvantage is avoided in that, firstly, the masticatory force is axially transmitted by a closed ring over the equator to the tooth and, secondly, the retention elements gripping under the equator are arranged so as to lie symmetrically opposite each other relative to the tooth centre line in such a way that rotating and tilting moments are avoided. The profiles of the clasps are prefabricated in wax in various shapes and dimensions.

Title: Control system for electric hotplate and oven - has piezoelectric relays and programmed control
Inventor: KORNRUMPF WILLIAM PAUL
IPC: H01H57/00
Filed: 1989-03-21
Abstract: The piezo-electric relays (50 to 56) are controlled by the programmed control (44,46,48) to connect the power feed to the electric heating elements. The controller can be temperature controlled and with manual override etc. The piezo-electric elements are shaped to require no basic holding current and only carry current when heating is required. The control can be for whole heating elements or for zone heating. The piezo-electric element has a pre-stressed section with a movable contact to connect to a fixed contact. The element bends when current is passed through. Each ohmic heating element has several piezo-electric relays for different current feeds and for progressive temperature control. ADVANTAGE - Compact relays, no leakage currents, simple heating control.

Title: Removing nitrogen cpds. from water - by nitrification and withdrawing carbon di:oxide before denitrification in amt. corresp. to carbon di:oxide formed
Inventor: BOECKLE RUEDIGER DIPL ING
IPC: C02F1/20
Filed: 1989-12-01
Abstract: In removal of NH4 and other organic N cpds. from water by a nitrification stage, in which the N is oxidised to nitrate, and a denitrification stage in which the nitrate formed is reduced to N2 with addn. of an electron donor as reducing agent, there is extracted from the water before the denitrification stage, an amt. of CO2 corresp. to the amt. of CO2 formed in the denitrification stage. Extn. of the CO2 is by blowing with air and the effluent air is used partly as O2 feed in the nitrification stage and is recycled into the extn. stage. Part of the water from the outlet from the denitrification stage may be recycled to the inlet of the nitrification stage, when the CO2 is withdrawn from the recycled water. USE/ADVANTAGE - Change of the water compsn. by accumulation of salts is avoided, less alkali is needed for neutralisation, the process is cheaper, and the carbonate hardness of the water can be regulated. The process can be applied to processing drinking water, cleaning ground water, and cleaning process water for re-use.

Title: Measuring force by sensor electrostatic force - contg. compensating pendulum pivoted between measuring and force compensating electrodes
Inventor: MASTNER GEORG DR
IPC: G01L1/08
Filed: 1990-05-03
Abstract: At least one pendulum (1) is pivotably positioned between at least one pair of measuring electrodes (3,4) initiated by an a.c. voltage and at least one pair of compensating electrodes (8,9). The pendulum delivers at least one current for further processing to an evaluating unit (11). An equal and constant potential is applied to the compensating electrodes for compensating the force. The evaluating unit supplies a rectified measurement signal (US) which is used to modulate the potential applied to the compensating electrodes. This modulation is carried out such that one electrode receives the sum and the opposite electrode receives the difference between the applied potential and the measurement signal. ADVANTAGE - No damaging feedback to measurement signal can occur allowing sensitivity to be increased. Relatively simple to adjust since us square relationship affects the measuring accuracy.
