Title: Tape measure with automatic digital read=out - uses direct fine division marking observation to avoid tape contamination errors
Inventor: KELLER HANS
IPC: G01B3/10
Filed: 1978-10-27
Abstract: A tape measure has a measurement tape with markings whose withdrawn length is determined and displayed by a sensor and processing device with a digital display. The problems inherent in optoelectronic reading of the fine divisions required for millimetre accuracy, e.g. dirt on the tape, are avoided by using the digital display(5) to show coarse division readings, i.e. centimetres, and having a direct observation window(6) for the fine divisions(3) or millimeteres. Therefore the bright-dark optical sensor scans special markings(4) for centimetres and the observation window has a reference mark(7) for fine reading. Alternatively, electronic scanning markers could replace the brightness -darkness fields on the tape. The direct visual display window can be a lens, thus magnifying the scale for more accurate reading.

Title: Slag deposit prevention - for coal gasifiers by heat radiation focussed on slag tap hole
Inventor: MEYER ADELBERT DR ING
IPC: C10J3/08
Filed: 1979-03-07
Abstract: Chilled slag is prevented from depositing in the slag tap hole of a coal gasification reactor by producing heat radiation and focussing it on the tap hole. Heat radiation is created by combustion of a fuel gas/air mixt. in an annulus above or below the tap hole, consisting of porous refractory material. Parabolic or spherical contours of the inside walls focalise the radiation on the tap hole. Slag tap hole is thus kept open as long as the reactor is in operation and ensures an uninterrupted production run.

Title: Knitted fabric incorporating woollen spun yarns - produced on a modified cylinder-and-dial machine
Inventor: GLICKLICH YOSEF
IPC: D04B9/12
Filed: 1979-05-29
Abstract: A conventional cylinder-and-dial machine adapted to permit the incorporation of woollen-spun yarns into the knitted fabric, having the cylinder latch-needles replaced by similar needles without latches, and the dial angularly displaced with respect to the cylinder, so that a selected proportion of cylinder needles, preferably every fourth needle, rises to its highest position before the dial needles advance. The selected cylinder needles engage a woollen-spun yarn, and then descend to place the yarn over the shanks of the corresponding, partly-extended dial needles. All the dial needles subsequently advance to knit a course of a conventionally-formed base fabric, on the face of which appear long floats of the laid-in woollen yarn. The invention converts a conventional machine into a multi-function machine, capable of handling softer yarns than previously possible.

Title: Pushbutton electric switch - has thrust action exerted by effect of transfer and simultaneous pivoting of two pressure members constantly engaged with movable contacts
Inventor: KURTZE GUENTHER PROF DIPL PHYS
IPC: F16F9/48
Filed: 1980-02-18
Abstract: The push-button electric switch includes one or more pivotally displaceable contacts (6,6') for each push-button (A,B). Reversal of the position of a displaceable contact or of the displaceable contacts of each push-button in a group is obtained by a thrust action on one part or the other about the pivotal point (5,5') of the displaceable contact or contacts (6,6'). The thrust action is exerted by effect of a transfer and simultaneous pivoting of at least two pressure members (9,9') in constant engagement with the displaceable contact (5). The transfer and simultaneous angular rotation of the pressing members (9,9') are derived from the translatory movement of the key-carrying slider (7).
