Patent DE-3928055-A1 (DE)
Title: Packing and unpacking machine for receptacles - has vertically guide gripper heads which can move additionally in event of faults and breakdowns
Inventor: HINZE WERNER
IPC: B65B21/18
Filed: 1989-08-25
Abstract: The machine for packing and unpacking receptacles has gripper heads rotating on chains and fixed on a vertically movable gripper head slide (6'). A lift cylinder (16) rotates with the gripper head slide (6) and engages on same. This cylinder is impinged in its continuous contact bearing position with a predeterminable contact and relaxing pressure. In the event of breakdowns and/or given requirements the cylinder can be controlled with an increased contact pressure so that the gripper head slide can be moved out of its high position determined by the contact on the curved track (8) into a high position removed therefrom. In the event of a breakdown during the change-over process the gripper head slide can be controlled and lifted independently of the curved track position by  means of fault detector units. USE/ADVANTAGE - Additional height manipulations of the gripper head are possible in the event of faults as well as the height movements determined by the curved track guide.

Title: Miniature switch for hearing aid - has pushbutton in casing, compressible against resetting spring force
Inventor: JANSSEUNE LUC
IPC: H01H13/58
Filed: 1989-09-08
Abstract: The push-button (1, 2) is non-rotatably mounted in a housing, and is compressible in the axial direction against the force of a resetting spring. The two front side inclined faces form sawtooth-like curves on the push-button, resulting in so-called ball-point curves (10a, b). Between the two curves protrudes radially a pin, secured to an axially movable rotary body in the housing. The tooth rows of the curves are so mutually offset that the rotary body is turned on each stroke of the push-button in one direction. On the housing are fitted contact elements engaging a metallised region of the rotary body for different switching state after push-button stroke. ADVANTAGE - Easy handling without risk to hearing aid.

Title: Radioactive gas scrubbing process - removes unwanted radioactive ingredients by rotating active carbon filter, recycling part of scrubbed gas
Inventor: GABRIEL CHRISTIAN DIPL ING
IPC: G21F9/02
Filed: 1989-12-20
Abstract: In a variety of chemical processes gases are generated which bear unwanted radioactive ingredients which are removed by means of a rotating active carbon filter. Part of the scrubbed gas flow is returned to the adsorbent, which it regenerates. This portion of the gas flow is then collected in a sealed container. USE/ADVANTAGE - There is no requirement for an additional supply of clean gas for use as a cleansing agent. Only a small portion of the gas becomes contaminated with radioactive materials. Operational requirements, the size and complexity of the equipment required, are reduced. The only gas which comes into contact with radioactive materials remains restricted to that portion of the gas which is piped to the scrubbing process.

Title: Feather bulking for construction of textile industry - reduces outer feathers to appearance and handle of down in wadding
Inventor: TOTH ARPAD
IPC: B68G3/10
Filed: 1990-02-05
Abstract: To process outer feathers which have been bulked and given an increased vol., they are prepd. according to application and are reduced in size by sorting during the bulking stage. Only feathers with a length of less than 10mm are allowed to leave the redn.  zone, so that outer feathers have the handle and performance of down feathers. During the processing, the feathers are filtered in at least one stage for moisture to be removed and dried to give a residual moisture content of less than 12%. In at least one stage, the feathers are reduced to a length of 11-20mm and then treated with a solvent pref. tenside with a neutral action and/or preservatives pref. with chlorogene or quat. ammonium bases and then the solvent and/or preservatives are forced out. ADVANTAGE - The technique gives a wadding of feathers which can be used as insulation in construction or the textile industries, which is easily packed and handled. It can also be used for packaging to protect goods from movement and changes in temp..

Title: Rod-shaped reinforcement component - has one or more circular bends flattened at bend point by rolling
Inventor: SCHOECK EBERHARD
IPC: E04C5/03
Filed: 1990-03-28
Abstract: The steel rod-shaped reinforcement component (3) has a specific dia. (d) which over a defined length is flattened to a determined height (h) by rolling. accordingly, an original round cross-section is converted into a virtual rectangular form on this length. This rectangular cross-section therefore has a thickness (h) which is smaller than the original dia. (d), and a width which is greater than it. At right-angles to this width, the component is bent with a specified dia. (D2) through 90 deg. The size of the surface for transfer of tractive force (F) from the reinforcement component to the surrounding concrete is determined by the width and the rolled bend dia. (D2). USE - Concrete reinforcement rods flattened at regions of sharp bends.

Patent DE-4031369-A1 (DE)
Inventor: WEISS HANS-RUEDIGER DIPL ING
IPC: G01L1/14
Filed: 1990-10-04
Abstract: The invention relates to a sensor, especially a pressure sensor, consisting of a field-effect transistor structure with a source electrode (3) and a drain electrode (4) together with a source-drain channel (7) and a gate electrode fitted to be adjustable above it, thus determining the gate capacitance. When the gate electrode is adjusted the gate capacitance also changes and hence the FET current can be controlled as a sensor signal by the charge effect in the source-drain channel (7). According to the invention, a pressure diaphragm (10) is integrated into the gate capacitance. The essential advantages are that a sensor which can be manufactured compactly by established methods, the pressure range of which is substantially determinable by the geometry and material of the diaphragm and can be produced without micro-engineering processes.
