Patent DE-19544691-A1 (DE)
Inventor: BRACHERT JOST DIPL ING
IPC: G05D1/08
Filed: 1995-11-30
Abstract: A system for determining a variable C v representing at least one slip rigidity in the case of a motor vehicle. The yawing motion * small Greek psi *', attitude angle * small Greek beta *, longitudinal velocity of the vehicle V, front steering angle * small Greek delta *v and optionally the rear steering angle * small Greek delta *h are measured, when defined operating conditions obtain, and at least the variable representing the front slip rigidity C v is determined as a function of the measured variables. In an alternative embodiment of the invention, measurement of the attitude angle * small Greek beta * is dispensed with. The front slip rigidity C v is then calculated as a function of the yawing motion * small Greek psi *', the longitudinal velocity of the vehicle V, the front and rear steering angles * small Greek delta *r , * small Greek delta *h and a fixed prespecified value representing the rear slip rigidity C h . This calculation also takes place only when defined operating conditions obtain. The preferred defined operating condition is stationary cornering, is when both the yaw acceleration * small Greek psi *'' and attitude angle velocity * small Greek beta *' are below predetermined thresholds for a predetermined period of time.

Title: Quantitative determining of pressure comfort of seat upholstery or cushioning esp. for vehicle
Inventor: FAUST EBERHARD DIPL ING
IPC: G01M99/00
Filed: 1996-01-20
Abstract: The method is carried out by mechanical loading using a test machine (5) having a seat testing plunger (4), which corresponds to the loading exerted normally with a sitting person. The pressure distribution on the sitting surface (2) or the back surface of the seat being tested is determined using a measuring mat (3). The mat has multiple pressure sensors which can scan the anthropomorphic points. The signals of the individual pressure sensors are separately evaluated in relation to the respectively associated pressure reception thresholds (po). The seat pressure distributions in individual regions evaluated with a determined formula are integrated. The integral values of all regions are added up, and the sum given serves as the valuation figure of the pressure comfort of the seat cushion (1) or the back rest cushion of the seat.
Patent DE-19610699-A1 (DE)
Title: Automotive single-plate dry clutch
Inventor: STRENG PETER
IPC: F16D13/64
Filed: 1996-03-19
Abstract: Asymmetrically distributed round its periphery the friction lining (3) has a number of interruptions or break points (5) arranged symmetrically respectively on rear and front faces of the clutch plate and specifically formed from indentations in the lining over different widths (b). Otherwise the break or interruption points can be provided by dissimilar characteristics of the lining spring sheets (2) arranged between the linings. The lining fixers (4) stand to differing height (h) off the spring sheets. The spring differences cause the lining to corrugate during clutching so by varying the spring strengths the break points (5) can be spaced asymmetrically round the lining. The indentations induce torsional variations during clutch engagement. Their asymmetric distribution causes high-frequency oscillations.

Title: Air=fuel control system for self-aspirating and self-compressing IC engine e.g. for motorcycle
Inventor: KLEINAU CHRISTIAN
IPC: F02M7/17
Filed: 1996-04-04
Abstract: The control system includes a feed back loop (4) in order to correct the actual air/fuel ratio so that it approaches a reference ratio. At the reference ratio an exhaust gas catalyser (3) would develop its most satisfactory cleansing performance based on the oxygen concentration in the exhaust gas. The control system adjusts the ratio to a value deviating from the reference value which makes the mixture richer or leaner. The system has a measurement device for determining the actual ratio the ratio control being applied to a constant velocity or constant pressure carburettor. The ratio control takes place by lifting the constant pressure piston(s) (7) of a constant pressure carburetter using a suction pressure from the induction pipe (6), from the air filter holder or some other source of partial vacuum. Alternatively by reducing the pressure above the fuel level in the float chamber of the above carburettor by means of the partial vacuum described above.

Title: Coal-cutting sequence employed in underground mining
Inventor: LOOS JOACHIM DIPL ING
IPC: E21C41/16
Filed: 1996-07-13
Abstract: The system is e.g. for mining coal from an underground seam without allowing roof falls, rock bursts etc. The rate of mining and the sequence of cutting the coal is optimised to avoid applying excessive stress to the rock strata as the settle into the void left by the removal of the coal. Easing of the strain on the strata reduces the likelihood of sudden escapes of gas, e.g. fire damp, choke damp etc. Flat or linear regions may be pre-drilled to induce resilience and reduce stress.

Title: Monitoring system for electrical machine star-connected stator windings
Inventor: JURISCH ANDREAS DR ING
IPC: G01R31/06
Filed: 1996-07-12
Abstract: The monitoring system detects the zero voltages at the terminals of the star-connected stator windings, with evaluation of their operating frequency component for provision of a release signal, with a second release signal provided by filtering out harmonics from the zero voltages to provide an intermediate value (MZ1).  The detected zero currents in the stator windings are similarly filtered to provide a second intermediate value (MZ2) with comparison of the phases of both intermediate values, to provide a phase angle compared with a defined range to obtain a release permit signal (AV1). An auxiliary value obtained from at least one intermediate value is compared with a threshold to provide a further release permit signal (AV2), the second release signal supplied in response to both release permit signals.

Patent DE-19633897-A1 (DE)
Title: Cavity wall insulation method
Inventor: DILGER WOLFGANG
IPC: E04B1/76
Filed: 1996-08-22
Abstract: The method involves mixing insulating material, in the form of free flow granules or beads, with fibres and blowing the mixture into the wall cavity under a pressure of 10-100 Pa to generate a turbulent flow inside. This blows the material into all parts of the cavity even above the insertion point. The fibres can be natural material e.g. coconut fibres, and have a length of 2-6 mm and a diameter of 0.2-1 mm. Alternately, wood fibres can be used, with a longer length and greater thickness. The fibres are treated with a flame retardant chemical before mixing with the insulating material. A binder can also be added to enhance the bonding of the granules. The fibre material is produced on site by a cutting machine which adds the cut fibres to the insulation via an air lock device.
