Patent DE-4040486-A1 (DE)
Title: Camshaft adjuster - has opposing meshing gear tooth systems for controlled rotation of camshaft w.r.t. camshaft timing gear
Inventor: SCHRICK PETER DR
IPC: F01L1/352
Filed: 1990-12-18
Abstract: A gear tooth system (30) meshes into a set of opposing teeth (31). As the teeth move an adjuster (44) turns the camshaft and the timing gear in opposite directions through a pre-set angle. The gear tooth system has a threaded section (45) which meshes at the same pitch with a counter-threaded section (46) of the teeth opposite. The counter-threaded section (46) is held in place by self-locking and/or bearing friction so that it will move only when forced to do so by the threaded section (45) and the adjuster (44). ADVANTAGE - Less energy used in angle adjustment; the angle is securely maintained during operation.

Title: Bar lathe with adjustable dia. guide bush - has slit guide bush which is closed onto bar by pressure of adjusting ring on tapered end section
Inventor: GROSSMANN WALTER
IPC: B23B7/06
Filed: 1991-02-06
Abstract: In an existing lathe design, bar is turned by traversing it past a stationary cutting tool. The bar is clamped by a collet (54) in the inner sliding spindle (46) of a telescopic spindle assembly (38). The outer spindle rotates in bearings (40,42) of the fixed machine headstock (12). The inner spindle rotates wit the outer spindle but can move in and out with the traversing slide (204). At the front end of the telescopic spindle is a guide bush (108) through which the bar is drawn when the inner spindle is traversed outwards to feed the bar past the cutting tool. In the invention the guide bush has slits and can be closed onto the bar by screwing the adjusting ring (106) against the tapered end section. Additionally it can be closed hydraulically by actuation of the piston (100). ADVANTAGE - Close adjustment of guide bush enables bar turning to be done very accurately irrespective of bar tolerance. Bar can be clamped in guide bush for conventional end working operations from turret.

Title: Peltier element for heat removal from silicon@ dice - is formed on a cantilevered part of a silicon substrate to avoid the degradation caused by a cooling substrate
Inventor: LANG WALTER DR
IPC: H01L23/38
Filed: 1991-02-13
Abstract: The Peltier element to remove heat from one or more dice comprises: a Si-wafer (1) with a thin Si-cantilevered membrane (2). On the membrane, an insulation layer (3) with a contact window (5) allows a single contact by the metal layer (4). The membrane is pref. formed by microstructural techniques, e.g. back-etching (8). The membrane (2) is pref. formed by epitaxial deposition followed by isotropic backetching reducing the contact between substrate and membrane (7) to a small area. The length and width of the cantilevered region are pref. 0.01-5 mm. The thickness is pref. 1-20 micron. The layer is doped to reduce the electrical resistance. The metal layer is a metal or alloy, pref. Al, Cu, Ag, Au or TiW, and is 200-1000 nm thick. USE/ADVANTAGE - The cantilevered construction allows less degradation of the effect by heat conduction in the substrate. The current consumption is reduced by making the current path parallel to the surface. The warming effect of the current is further reduced by reducing the resistance of the Si layer. The Peltier element can be used to cool several dice at once, which can be electrically insulated from it. It can be easily constructed using standard techniques. The structure is used in the mfr. of dew-point indicators, using the metal layer as a mirror and placing a thermocouple on it via an insulating â

Patent DE-4141837-A1 (DE)
Inventor: SCHRAMM GUENTER
IPC: H02J7/14
Filed: 1991-12-18
Abstract: The description relates to a device and process for regulating a generator by means of which increased generator output power can be obtained either because the exciting current can assume a value above the rated exciting current or because the generator is so designed that overheating can occur in unfavourable circumstances. To prevent overheating from occurring even in unfavourable circumstances, the temperature is measured preferably in the regulator and the temperature at critical points is found from this temperature, taking account of typical parameters. This temperature measurement takes place in a special manner in that first the temperature or temperatures is/are found which would occur in steady-state conditions. On the detection of an unacceptably high temperature, the exciting current is reduced by suitable means so that the permissible maximum temperature is not exceeded.

Title: Impregnating substrate by contact with supercritical fluid contg. impregnant - followed by conversion of fluid to subcritical state
Inventor: KNITTEL DIERK DR
IPC: C08J7/044
Filed: 1992-01-29
Abstract: In impregnation of substrates, the impregnant is taken up in a super-critical fluid and the substrate is contacted with the fluid. During and/or after the contact, the fluid is converted to the sub-critical state. Impregnation is at 10-300 (32-180) deg.C and 60-400 (140-300) bars. The supercritical fluid is an alkane, esp. ethane, propane or pentane, NH3, a fluorochloroalkane, CO2 and/or CO, opt. contg. 1-10 (2-5) vols.% of a moderator. The impregnants are preservatives, light protectants, plasticisers, hydrophobising or hydrophilising agents, antistatics, anti-parasite agents, bactericides, bacteriostats, perfumes, flavourings, and/or dyes. After the given time of application, the pressure is reduced in stages. USE/ADVANTAGE - The process is environment-friendly, uses no organic solvent, and gives a substrate free from residues of fluid. The fluid and residual impregnant can be collected and re-used. Claimed substrates are natural substrates, ceramics, leather, paper, wood, books, antiquities, cereals, plant seeds, seed corn, foods, luxuries, medicaments or carriers for medicaments, pharmaceuticals or pharmaceutical additives, rubber, synthetics, waxes and soaps.
