Abstract: A material for covering mattresses, pillows or eiderdowns comprises a compact polyurethane membrane, permeable to water vapour, reinforced on at least one side with a flat textile. The PU membrane is pref. prepd. by the reverse process, or the PU layer, with flat wt. 25-125 (40-100) g/square m, is prepd. by direct stretching. The textile reinforcement or covering is elastic, partic. a polyester or polyamide woven fabric with flat wt. 30-120 950-100) g/square m. The material is washable and has Chopper water-tightness of at least 2000 mm WS. USE/ADVANTAGE - The material prevents allergies caused by house-dust mites. The material does not rustle and forms non-wrinkling covers. The permeability to water vapour is 1500-4000 (3000-4000) g/square m/24 h (Lyssy method) allowing of penetration of body moisture into the mattress. In an example, a polyester fabric was coated on the smooth side, by the reverse process with a "Impraperm" 43176 (RTM) (bonding layer) and 43174 (top layer) to give a total dry wt. of 40g. The two sheets were then heat-bonded by the coated sides. The material was fast to boiling at pH 8.5 (more than 100 washes) and hard water-tightness above 3000mm water vapour permeability 3500 g/square m/24 h and high mechanical strength. (3pp Dwg.No.0/0)

Patent DE-4100666-A1 (DE)
Inventor: KRANITZKY WALTER DR
IPC: G06J1/00
Filed: 1991-01-11
Abstract: With an interpolation circuit (1) according to Figure 1, an instantaneous vector (21) is formed for subdivision of measurement signals (sin, cos) which are phase-shifted in relation to one another. With the aid of a vector generator (2), a reference vector (20) is generated which is approximated in stages to the instantaneous vector (21). Analog values of both vectors (20, 21) are compared in comparators (6, 7) and a control logic (3) controls the vector generator (2) depending on the result of the comparison. If the approximation of the comparison vector (20) to the instantaneous vector (21) is adequate, this successive approximation is interrupted and the intermediate value is output according to angle and amplitude via output lines (15 and 16). <IMAGE>
Patent DE-4103931-A1 (DE)
Inventor: PARZEFALL WALTER
IPC: F16D23/14
Filed: 1991-02-08
Abstract: The invention relates to a stabilising and supporting device (1) for the pivot of a clutch release lever (10). It consists of a securing bolt (2) with a polymeric securing section, a pivot region on the side towards the clutch lever and two stabilisation regions (3, 4) diametrically opposite the longitudinal axis (15) of the bolt, wherein there are a thickened region (6) on the securing bolt and an extension section (8) after it. To optimise stabilisation and the correctness of the pivot, the securing section (9) takes the form of an axial section which can be accepted peripherally within an aperture edge (12) of the clutch lever for radial guidance. In the operating condition, the two stabilisation regions (3, 4) are centred with respect to the longitudinal bolt axis by the thickened region and connected together via a connecting pin (25) with a central aperture (26) to take the thickened region so that it can move, and in the production condition are connected with the securing bolt via a connection section (36) with a predetermined breaking point (37), and the entire device is made of polymeric material.
