Patent DE-4028707-A1 (DE)
Inventor: NOLD JOACHIM
IPC: A01D34/08
Filed: 1990-09-10
Abstract: A hand-guided motor-driven tool, especially mower, having one or two axles with wheels and having a handle (9) which possesses especially two handle parts and which is mounted on the tool by means of two bearing axles (12, 13) which extend transversely relative to one another and which are inserted into elastic bearing elements (16, 17, 18, 19) of bearing parts (24, 29), is to be designed in such a way that, whilst a damping of the oscillations or vibrations transmitted from the tool to the handle (9) is guaranteed, the constructional size of the tool or of the elastic bearings (11) for the handle (9) can be reduced. This is achieved in that the bearing axles (12, 13) are arranged in a T-shaped manner or crosswise relative to one another, so that the longitudinal mid-axis (15) of one bearing axle (13) essentially intersects the longitudinal mid-axis of the other bearing axle (12) in its middle region. <IMAGE>

Title: Marker for optical angle coder - has stator with cylindrical side wall, with electrodes on latter and on bottom and cover walls
Inventor: POLSTORFF WALTER K DR
IPC: B23K26/00
Filed: 1990-11-02

Title: Electric heater apparatus for dental applications - removes compressed air supply to cause piston to return to quiescent position under spring tension
Inventor: HERTER KARL
IPC: H05B3/14
Filed: 1990-05-21
Abstract: The heater chamber (61) contains a channel (64) in which the medium, preferably water, is heated to body temperature by a flat PTC - thermistor heating element (65). Water input (67) is via a spring loaded valve (76) held in the open position by a spring loaded piston assembly (77.78) which is activated by a compressed air input (79). When the heater apparatus is switched off the compressed air supply is removed causing the piston (77) to return to it's quiescent position under spring tension, creating a vacuum which sucks the residule water from the heater chamber (61) preventing an unwanted output seepage. USE/ADVANTAGE - Used in dental applications to supply body temperature cooling water to treatment area - eliminates unwanted output seepage after apparatus is switched off - volume of suction chamber is adjustable via an internal spindle - fitted with temperature sensor and control facility.

Title: Vacuum switch contact arrangement for deterministic arc switching - has current paths at rims of discs with components directed radially towards axis of contact carriers
Inventor: SLAMECKA ERNST PROF DR TECHN
IPC: H01H33/664
Filed: 1991-03-17
Abstract: Hollow cylindrical contact carriers (3, 3') on current conductors (2, 2') are asscoaited with contact and electrode discs (5, 5') having recessed centres (6, 6'). The hollow cylindrical inserts (12, 12') in the unrecessed rims (7, 7') are deep enough to define annular gaps (19, 10') directed inwards. The rims overlapping the gaps are supported by poorly-conducting annular discs (13, 13'). The circuit-breaking arc between the outer contact areas (7, 7') experiences an inwardly directed force causing it to become diffused into the central recesses (6, 6'). ADVANTAGE - Arc erosion of contact area is reduced while contact resistance is lowered by greater pressure without recourse to costly supports.

Title: Arrangement for monitoring tyre state and wheel rotation parameters - has encoding element mounted on wheel hub contg. multiple magnetic ring and microcoil
Inventor: RIGAUX CHRISTIAN
IPC: G01D5/14
Filed: 1991-11-26

Title: Formation of cylindrical insulation layer in semiconductor substrate - using self-aligned etch process resulting in smooth field oxide on top surface
Inventor: JUN YOUNG KWAN
IPC: H01L21/76
Filed: 1991-11-28
Abstract: An insulated layer for use in a semiconductor device is formed by etching a narrow and deep cylindrical trench, filling it with an oxide layer and oxidising a polycrystalline Si layer. A process is also claimed. The process consists of forming an oxide layer on a Si surface followed by a nitride layer. Using a resist process a window is defined and etched. Then a polySi layer is deposited and channel stopper dopants implanted through it. The surface is planarised by deposition of an oxide layer which forms a plug in the etched window and is etched back until the polySi is reached. The Si exposed at the surface is then etched back and the process continued into the substrate where no masking oxide or nitride is present. Then a CVD oxide layer is deposited and etched back using a dry etch process until the polySi layer is laid bare. Then the polySi layer is oxidised and the nitride layer removed. USE/ADVANTAGE - The process is self-aligned, with the width of the trench defined by the thickness of the polySi layer. The field-oxide layer on top of the structure is even and without ripples.

Patent DE-4224729-A1 (DE)
Title: Tissue paper mfg. machine - has stretch belt to crepe and detach paper at the tissue cylinder without cylinder wear
Inventor: STEINER KARL DR
IPC: D21H25/00
Filed: 1992-07-27
Abstract: To separate tissue paper from the drying cylinder, in a papermaking machine, a stretch belt at the crepe scraper simultaneously crepes the paper and detaches it from the drying cylinder. At least two tensioner rollers, supporting the stretch belt, apply tension to press the belt against the tissue cylinder. The first tensioning roller, in the direction of web travel, has the same dia. over its whole width and is held against the tissue cylinder separated from it by the tissue web and the stretch belt. The second roller, in the direction of web travel, has an increased dia. at the edges, such as cogwheels, to engage the surface of the tissue cylinder where there is no web present, to rotate at a slower speed than the first roller. The continuous stretch belt passes round both the rollers, and round a significant stretch of the circumference of the tissue roller before passing back round the second roller. A moving tensioning roller applies the required tension to the stretch belt. The stretch belt is pressed against the tissue cylinder by a roller with a smaller dia. with a claw round most of its circumference over its whole width, with an inner oil cushion to support the roller, or an air cushion gives roller support. The roller can also be supported within the claw by a water cushion, or a number of bearings over its width. The stretch band can be held against the tissue cylinder by a shoe press. The stretch belt has an embossed or structured surface, with non-stretch threads on the side towards the paper, generally or exactly along the belt line of travel, or diagonally to the belt travel direction, or generally or exactly across the belt line. ADVANTAGE - The mechanism reduces the wear on the tissue cylinder through the scraper action.

Title: Compact filter changer for a radiation emitter - has a linkage arrangement for movement of filters vertically upwards into the beam path and also parallel to the beam path to change filters
Inventor: HOLZERMER GUENTER
IPC: G21K1/04
Filed: 1992-09-02
Abstract: A filter changer for a radiation emitter. The filter (3) is inserted into the radiation path by a linkage made up of an arm (1) whose first end (2) engages the filter and whose second end is attached to an axle (5). The arm swings around the axle thereby working against the spring (20) to move the filter from a lower position (6) to an upper position (7) in the radiation path. The filter is returned to its initial position (6) by the springs force. The filter (3) can be positioned in a parallel but forward positioning path and this permits exchanging of filters where more than one filter is available. USE/ADVANTAGE - The filter changer is intended for use with X-ray emitters. The construction of the filter changer is compact and therefore cheap to produce. By enabling movement of the filter perpendicular to its up and downwards movement different filters can be selected.
