Patent DE-2838524-A1 (DE)
Inventor: GRAEBER AUGUST
IPC: B29C48/00
Filed: 1978-09-04
Abstract: The cable (4) to be vulcanized is moved axially through a vulcanising device (2) and a housing (6) in the form of a jacket flanged to the said device. To seal off the annular space surrounding the cable (4) in the housing (6), two seals (8, 10) arranged in series are provided, each having a sealing ring (12 and 14 respectively) of elastomeric material, the conical inner portion of which can be pressed into sealing contact with the outer circumference of the cable (4) by actuation of a pressure ring (16 and 18 respectively). In normal operation, the first seal (8) is actuated, and this wears relatively rapidly. To enable the first seal (8) to be replaced, the second seal (10) is actuated. It is thus possible to replace the first seal (8) without interrupting operations. <IMAGE>

Title: Photoelectric pulse generator with two shutters - includes hoes whose size and spacing allow flat construction
Inventor: KIRCHHOFF ROLF DIPL ING
IPC: G01D5/347
Filed: 1979-01-05
Abstract: The photoelectric pulse generator has two shutters one behind the other in the light path from a light source to a photodetector. The shutters have slots to allow light to pass through. One shutter rotates and the other is stationary. The spacing (b') and the openings (a') in the shutter (4) farther from the light source (1) are larger than those (a, b) of the shutter nearer the light source such that light can pass unhindered through both shutters. The light source is located very close to the shutters without needing a lens system -- which means that the generator may be very flat.

Title: Common transmission bridge for two local subscribers - uses shunted dialling relay or low resistance bifilar choke
Inventor: DIRR JOSEF ING GRAD
IPC: H04Q1/32
Filed: 1979-03-08
Abstract: The same transmission bridge can be used for two or more subscribers, connected via an exchange in three possible ways. The transmission bridge consists initially of the relay which detects the calling subscriber's dialling pulses. When the connection is made, the dialling relay is by-passed and replaced by a low resistance relay whose function is to detect hanging up on completion of the call. A bifilar choke and a transformer are used, with a low enough resistance not to need by-passing. Dialling pulses in a tertiary winding of the transformer are detected electronically. A low resistance bifilar choke is used and the dialling current pulses are detected electronically, pref. by an opto-coupler connected directly in the loop.

Title: Hospital floor cleaning implement - combines scrubbing, wiping when dry and wet, has long handle with bottom frame and rollers, with cloth
Inventor: HUEBNER GUSTAV
IPC: A47L13/24
Filed: 1979-03-12
Abstract: The floor cleaning implement cleans itself automatically; is easily handled by the operator; and can be used for scrubbing, dry and wet wiping. An absorber cloth (7) is fixed to the lower end of a long handle (1) and is suspended flat from the cleaning part between the squeezer rollers (10) and the cleaner rollers (9). A scrubbing brush (6) is attached to the top edge of the absorber cloth (7). The scrubbing brush is fixed between the sides of a triangular frame (2) at the bottom end of the handle (1). The flexible sides of the frame (2) are splayed out by means of a sliding grip which can be looked in any position.

Title: Extending drawer guide rail system - has rotatable tilt segment interacting with rail on chassis for precise control of rails (OE 15.8.79)
Inventor: ROECK ERICH
IPC: A47B88/493
Filed: 1979-03-26
Abstract: The extending drawer guide has extension rails on either side of the drawer and support rails (14) on the carcase. They can slide on at least one, pref. two supports (3, 4) and they are attached for articulated movement to a tilt segment(8) which is rotatably mounted on the carcase. The drawer (2) or a part fixed to it has a guide groove (10) or recess open to the back so that when the drawer is closed a drive pin (9) mounted on the tilt segment (8) can project into the recess. Alternatively, the drawer can carry the drive pin which when the drawer is closed engages the groove on the tilt segment. The rail on the carcase is drawn out at the same time as the drawer so that the weight of the latter passes directly to the sliding parts of the carcase rail and not via a lever transmission.
Patent DE-2914042-A1 (DE)
Title: Multicavity mould for plastic foam - with lower half guiding upper half prior to contact
Inventor: JUERGES HEINZ-HENNING
IPC: B29C44/38
Filed: 1979-04-06
Abstract: Small articles of expanded plastic, specially polyurethane foam, can be mass produced in multi-cavity moulds consisting of two halves. The bottom half of the mold is the space in which the components are poured; it consists of a recess to act as a guide for the top mould and has a number of recesses for the articles. The top mould is a movable plunger which has on the underside the same number of cavities as the bottom mould and, in addition vent holes. During the foaming process the two halves are kept at a distance from each other, but form a closed mould space. When the pressure inside has dropped to below half the maximum, the two halves are pressed tight against each other. This results in articles of uniform quality without flash or dead heads.

Title: Luminescent coating of selected cells - uses electrophoretic development of electrostatic charge pattern for gas discharge display
Inventor: SCHMIDT ROLF DIPL PHYS DR
IPC: H01J17/49
Filed: 1979-04-18
Abstract: A gas discharge matrix display comprises a back-plate (1) with X electrodes (20-29) and a cover plate (6) with Y electrodes (50-55). The intervening space is divided into a matrix of rectangular cells (7) aligned with the electrodes, by cell walls (4). During manufacture, the cell walls are coated with luminescent material by applying sufficient voltage to selected X and Y electrodes to ionise the air in the corresponding cells and charge their walls electrostatically. The cover plate (6) is then removed and the charge pattern 'developed' by electrophoresis from a liquid suspension or dry powder. The process is then repeated, using different X and Y electrodes, to apply a different colour to other cells. Finally, the cover plate is fixed in place, air exhausted, and the matrix filled with the working gas.
