Patent DE-4304978-A1 (DE)
Title: Improving quality of foam structure in production of rim mouldings - by homogenising mixt. in high pressure circulation before mixt. is supplied to actual mixing head then fed to mould
Inventor: SCHAPER HERBERT DIPL CHEM DR
IPC: B29C44/34
Filed: 1993-02-18
Abstract: In the foam structure of RIM mouldings, partic. those in polyurethane or polyurea, a homogenising device is used in the high pressure circulation of the RIM metering layout before the mix enters the mixing head. Normal high pressure circulation systems pref. have the valves (3,9) closed Valves (5,6) are closed and valves (8,9) are then opened, when the circulation stops. Complete shot of liq. must now flow through the homogeniser (7) before entering the mixing head (2). ADVANTAGE - System produces great turbulence in the resin mix and hence disperses large bubbles, or removes other forms of variation in the material, which either go into soln. or are at least distributed through the mix in fine form.

Title: Module and method for producing it
Inventor: SOPKA JOERG DR
IPC: H01G9/20
Filed: 1993-03-02
Abstract: The invention relates to a module (1) which is formed by the series connection of at least two photoelectrochemical cells (2, 3, 4). The series connection is performed via cell connectors (6 and 7) which are produced from a paste. The paste is applied either to the first or to the second electrically conducting layers (2E, 3E, 4E and 2G, 3G, 4G, respectively). An epoxy resin and a metal powder is used to produce the paste. <IMAGE>
Patent DE-4310247-A1 (DE)
Title: Process for producing light workpieces which are stiff to flexure and torsion (bending and twisting) by composite casting
Inventor: WACKER JOSEF DIPL ING
IPC: B22C7/00
Filed: 1993-03-30
Abstract: A pattern is produced from a material which can be melted out, dissolved out and/or burnt out, which pattern can subsequently be provided with a ceramic shell (S) by coating with a ceramic slip and subsequent drying. After removal of the pattern, for example by melting out, the ceramic shell is fired and then a solidifiable material is cast into it to produce a composite body having a ceramic outer shell. For casting into the ceramic outer shell, metal, in particular steel, can be used. However, the ceramic shell (S) can also have a ceramic material cast into it, whereupon the entire structure is fired. The process of the invention is distinguished by the possibility of optimum construction and by the properties of the ceramic shell (S) of the composite body, which properties contribute, at a low proportion by weight, to a high flexural and torsional stiffness. The process of the invention is preferably used for the production of portals (travelling bridges) for positioning and placing systems. <IMAGE>

Patent DE-4318089-A1 (DE)
Title: System for the automatic taking, provision and preparation of liquid and solid samples
Inventor: WILDANGER HANS-JOERG
IPC: G01N35/00
Filed: 1993-06-01
Abstract: Taking, providing and preparing liquid and solid samples in automatic analysis systems has to date required high investment, large spatial demand and a high degree of manual work. By virtue of the novel system, investment, spatial requirement and labour expenditure are intended to be substantially reduced. A system is used which consists of a sample holder and a handling robot, a strip with pockets formed in it being used as the sample holder. The strip and the pocket have sufficient elasticity, so that the strip can be rolled up to save space and can be transported simply using the handling robot. By exerting force on the pocket (3 and 6) disintegration and dissolving of solid samples, dilution and mixing of liquid samples or the transport of liquid is made possible. Auxiliary means for sample treatment such as, for example, a filter (5) can be integrated into the strip. The novel system can be used for automatic sample preparation for compositional determination of solid medicinal compounds. <IMAGE>

Title: Ultrasonic positioning technique for medical measurement
Inventor: BRUNNER WOLFGANG
IPC: A61B5/103
Filed: 1993-12-28
Abstract: The technique involves determining the spatial position of measurement points using an ultrasonic positioning system. Measurement uncertainties occur due to system noise on the signals. Instead of the usual three transmitter-receiver pairs, it is proposed to use further T-R pairs, and to optimise the measurements by calculation of individual triples, rejecting the poorest values and averaging others.

Patent DE-4426446-A1 (DE)
Title: Electric toothbrush
Inventor: INAKAGATA SATORU
IPC: A46B15/00
Filed: 1994-07-26
Abstract: There is specified an electric toothbrush with a control circuit which can terminate the brushing process if the brush is pressed with excessive pressure against the teeth. It comprises a housing (10) with a shaft (13) on which a brush (31) can be attached. The housing comprises an electric torque motor (21) and a movement translation mechanism (22) which translates the rotating movement of the motor into a to and fro movement of the shaft in order to move the brush to and fro. There is a pressure sensor (25) for measurement of the brush pressure as it acts back upon the brush as counter-force when the brush is pressed against the teeth, and which produces a stop signal when the measured brush pressure exceeds a predetermined limit value. The stop signal is supplied to the control circuit which is switched so that it stops the motor in response to the stop signal. In this way, the electric toothbrush can stop the motor if the brush pressure increases excessively in order to provide a reliable protection for teeth and gums. <IMAGE>
