Patent DE-4221909-A1 (DE)
Title: Vehicular antilock braking system determining carriageway friction coefft. - selects hydraulic pressure variation mode according to comparison of wheel deceleration with safe max. vehicle deceleration
Inventor: OKUBO SATOMI
IPC: B60T8/1763
Filed: 1992-07-03
Abstract: Individual wheel rotational speeds are calculated (12) from the four tachometer readings (1). A pseudo-road-speed calculator (13) selects the highest wheel speed and limits the acceleration and deceleration within a predefined range. Upper and lower thresholds (VT1,VT2) are calculated (14) and a reference speed (Vr) is reduced when deceleration (g) of the nearside front wheel (FR) attains a predetermined value. The max. vehicular deceleration (Gmax) taken from a diagram (18) is compared (19) with the wheel deceleration (g). ADVANTAGE - Reliable and stable system limits changes in hydraulic pressure and wheel speed as necessitated by variable road surface condition.

Title: Cordless, detachable speech unit
Inventor: LAUTERBACH RAINER
IPC: H04M1/02
Filed: 1993-04-02
Abstract: According to the state of the art, speech units exist which can be plugged via a cord into cordless telephones. The cord restricts freedom of movement. For the cordless speech unit for cordless telephones, along with the radio link with the telephone network, a second short radio link is set up between the telephone body and the speech unit. The speech unit is simply attached like the front part of a car radio and can serve in the interconnected and detached conditions as the speech unit of the telephone. The advantage is that the telephone can be inserted in the pocket during the call and the speech unit attached, leaving both hands free. The telephone which can be interconnected has the same appearance as conventional cordless telephones and, as additional equipment, has the cordless, detachable speech unit. The short distance between the speech unit and the telephone body allows a miniature battery and a very small transceiver unit to be used in the speech unit. Field of application: In cordless and cord-connected telephones, radio units, car phones and handheld telephones. Commercial and private applications worldwide.

Title: Micromechanical sensor and method for its production
Inventor: MUCHOW JOERG DIPL ING
IPC: G01B7/00
Filed: 1993-06-03
Abstract: A micromechanical sensor and a method for its production are proposed, which sensor consists of a silicon substrate (1) having a silicon epitaxial layer (5) applied onto the silicon substrate. Using an etching process, a part of the epitaxial layer (5) is uncovered as at least one micromechanical deflection (displacement) part (12 to 15). According to the invention, the uncovered deflection part (12 to 15) consists of polycrystalline silicon which has grown in polycrystalline fashion during the epitaxy process above a silicon oxide layer (2) removed by etching. In the support region, or at the connection with the silicon substrate (regions 6, 7) there is transition of the uncovered deflection part into monocrystalline silicon. A large working capacity of the sensor is possible as a result of high layer thicknesses. The sensor structure is distinguished by advantages in regard to mechanical stability, ease of processing and configurational possibilities and can, in particular, be integrated in a bipolar process or hybrid process (bipolar CMOS, bipolar CMOS/DMOS). <IMAGE>

Title: Yarn clinging test
Inventor: SOLIMAN HOSNY DR
IPC: D03J1/00
Filed: 1993-12-15
Abstract: To test the clinging propensity of yarns, when in contact with each other, two yarns are drawn into a test zone and they are brought together with a local, linear or spiral contact. The yarns are sepd. to simulate their movements in a loom shed, together with scanning of the sepn. between them, and the two yarns are withdrawn from the test zone.The yarns are braked before insertion into the mutual contact zone. When the first yarn is inserted, a braking action can be applied to it to draw it back, and then drawn through as the second yarn. The two yarns can be of different qualities and of different materials. They can be drawn continuously through the test zone, or at least one yarn is moved through in steps. They can be moved through at the same or different speeds, by an adjustable and constant braking force.

Title: Holding device for heating pipes (tubes)
Inventor: FUCHS ALFRED
IPC: F24D3/10
Filed: 1993-12-30
Abstract: For the installation of a central-heating system in a building, heating pipes are laid on the unfinished floor of the structure and in each case led up to the radiator concerned from below. Until now, it has been possible for the heating pipes to become bent during the laying of the screed. A novel holding device for heating pipes is to be suitable for all distances of radiator connections occurring and various screed heights. A holding bracket (5; 91) has a base part (9; 99) and a rail (8; 98) pointing away therefrom and having a number of openings (10; 100) provided on it in grid fashion. The holding bracket includes a sleeve (12; 102) having at least one or more holding elements (pegs 15; 95) insertable, at the appropriate place as required, into the openings (10; 100) on the rail (8; 98). The rail has either a V-shaped or a substantially rectangular cross-section or is of flat design. it runs substantially perpendicularly to the base part (9; 99). The holding device is suitable for any radiator and any screed height, with the result that its storage is simplified and the selection of a given holder for a given radiator and a given screed height is dispensed with. <IMAGE>

Title: Multilayer surface processing of plastic workpieces by dipping
Inventor: KAUPER RUDOLF
IPC: B05D5/06
Filed: 1994-09-03
Abstract: The electrolytic metallising and subsequent lacquering of workpieces made of plastics in manual or automatic dipping bath installations is such that the electroplating and lacquering installations are combined so that they can be operated by the same transport, workpiece carrier and processing frames without transfer of the workpieces from frame to frame, and the need for drying after electroplating is eliminated by use of water-soluble or water-dispersive lacquer - which hardens at low temperatures - for wet-lacquering.
