Title: Filling stage for a brake master cylinder
Inventor: BURGDORF JOCHEN
IPC: B60T11/18
Filed: 1988-05-11
Abstract: The function of a filling stage is to deliver pressure medium into the wheel brakes within a short actuation travel during the first brake actuation phase in order to overcome the lifting gap and to permit a large pressure build-up in the wheel brakes for low actuating forces in the pressure phase. Proposals have hitherto provided for the arrangement of the filling stage between the master cylinder and the point of introduction of the actuating force. In the following, an auxiliary device to a master cylinder is proposed, which assumes the function of a filling stage. In the basic position of the piston (4) shown, the pressure medium passage (19) is opened so that in the first brake actuation phase (filling phase) the face (18) of the master cylinder piston (17) is operative. As soon as a pressure is generated in the wheel brakes which is capable of displacing the step piston (4) against the force of the spring (25), the valve (20, 21) closes, so that now the face (6) acts to build up pressure. <IMAGE>

Title: Division of extruded material into separate smaller portions - opposing notching wheels form weak parting lines between portions sepd. by faster running conveyors and delivered equally spaced
IPC: A23G3/06
Filed: 1989-10-24
Abstract: Equipment for dividing a continuous extrusion of a tough elastic material into smaller sections and improving the speed of a current process is new. In the new process the extrusion is continuously moved forward and notched at right angles to the direction of travel and at regular intervals by two opposing notching wheels. Notches are formed on both sides of the extrusion such that only a thin section of material remains, thus forming a parting line between sections. Two opposing belts running at a faster speed pull each front portion away from the others along the weak, notched line. Individual portions are then equally spaced and removed on a caterpillar conveyer. Equipment comprises feed and calibration rolls, notching wheels, clamping rolls, separating, constant spacing and caterpillar conveyers. USE/ADVANTAGE - Dividing tough, elastic material typically rubber or toffee extrusion into smaller portions. The process is continuous and is faster than a current process.

Title: Measuring blood pressure by oscillation method - calculating value(s) from 2 series of pulsation pressure waves received during contrary sense changes in pressure
Inventor: KUENECKE PETER DIPL ING
IPC: A61B5/0225
Filed: 1989-12-18
Abstract: A sleeve can interrupt the pulsating pressure waves of the blood flow by applying a variable external counter-pressure. These pressure waves modulate the external pressure and are converted to electrical signals by a pressure sensor. The latter continuously senses changes in the external counter pressure dependent on the patient's diastolic as well as systolic blood pressure values. At least one blood pressure value (Ps,Pm,Pd) is calculated from the changes (12,13) of the pressure sensor signals during a first continuous variation of the counter pressure as well as during a directly following second change in the opposite sense. A mean value is electronically formed from at least two simultaneously available and similar type of blood pressure values. This average value is the blood pressure value to be displayed. ADVANTAGE - Reduced demands on mechanical pressure control(s) despite limited load on patient.
