Patent DE-4024483-A1 (DE)
Inventor: SAALBACH KURT
IPC: F15B7/08
Filed: 1990-08-02
Abstract: The invention concerns a master cylinder for hydraulic systems, in particular brake systems. The aim of the invention is to reduce the return stroke of the piston (3) conditioned by a compensation aperture (7) in the cylinder wall (1). The invention achieves this aim essentially by calling for the compensation aperture (7) to be oblong, preferably elliptical, in cross-section (10), with the major axis (C) of the ellipse perpendicular to the cylinder axis (D). The invention also includes a process for producing an aperture (7) as required by the invention. In this process, a bore (11) which does not pierce entirely through the cylinder wall is first made from the outside, and an aperture shaped as required by the invention subsequently stamped out from the remaining thickness of wall.

Patent DE-4028465-A1 (DE)
Title: Automatic yarn splicing -  has monitor between the spinner and the splicer to trigger the operation through program control according to actual conditions
Inventor: STRAATEN PAUL
IPC: D01H13/22
Filed: 1990-09-07
Abstract: During an automatic yarn splicing operation, to repair a broken yarn between the spinning and winding stations, it is monitored between the spinning station and the splicer to check the presence of the yarn. When the yarn is detected, it is taken automatically in the spinning operation and/or the splicing action with measures to prevent subsequent faults, or interrupt the yarn splicing or to initiate a new splicing action, to remove a loose yarn and/or generate a fault indication. When it is detected that the thickness or mass of the yarn splice or the yarn lie outside tolerance limits, the yarn is cut upstream of the splicing unit, and the yarn end with the out-of- tolerance length is wound on the bobbin, or the spinner is stopped, and the unacceptable yarn length is drawn from the yarn store or collector and the splicer, and wound, and a fault indication is generated. The unacceptable length is then withdrawn from the bobbin, and cut away before a new splice is formed, and the waste length is sucked clear for removal. ADVANTAGE - The method reduces faults in the yarn splicing operation and increases the number of effective yarn splices to increase the effectiveness of the spinning assembly.

Title: High speed synchronous data transmission between facsimile devices -  dividing data into blocks before high bit-rate asynchronous transmission between lower bit-rate synchronous peripheral devices
Inventor: LORENZ HANS JUERGEN DIPL ING
IPC: H04L5/24
Filed: 1990-09-10
Abstract: The high speed transmission system used for communication between two facsimile devices allows matching between the high speed transmission path and the peripheral devices which operate at a slower speed.

Title: Measuring mass flows of multiple component flow e.g. oil-water-gas - involves polarising flow to saturation in magnet and measuring magnetisation along pipe
IPC: G01F1/74
Filed: 1991-06-14
Abstract: The method of measuring the mass flows of a multiple component flow with a nuclear magnetic moment involves using the different products of speed and associated spin-grid-relaxation time for each individual component to measure the individual mass flows. The flow is polarized in an input magnet of sufficient length so that every component is continuously saturated. Varying magnetisation along the pipe is produced by the outflow motion of the multiple component flow. The point along the pipe is determined at which the magnetisation has decayed until only the component with the maximum product contributes to the magnetisation (M(s)). ADVANTAGE - Enables mass flows to be determined without physically separating the components.
