Patent DE-2359471-A1 (DE)
Title: Venetian blind or roller shutter raising drive - with universal joint ball socket as stop for ball-connected spindle
Inventor: ERB WALTER
IPC: E06B9/76
Filed: 1973-11-29
Abstract: The raisable and lowerable window-screening device incorporates a roll-up shaft, with drive comprising a drive shaft with hand crank and universal joint for coupling to the roll-up shaft. This joint is in the form of a ball joint transmitting rotational moments, and the ball socket, of which the edge serves as stop for the attachment position of a spindle connected to the ball. This stop comes into operation at the max. permissible degree of bending. The ball may have two grooves with diametrally opposed meridians with carrier balls engaging in them and pressed into the ball socket. Excessive bending of the ball joint is prevented, precluding fracture or premature wear.

Title: Collision absorbing car bumper - with array of shear pins for energy absorption from sliding bumper channels
Inventor: FICKENSCHER HANS
IPC: B60R19/18
Filed: 1974-02-04
Abstract: The bumper is fitted to the car body by means of a W-shaped metal profile with the arms of the W directed forwards. The bumper bar is held inside the outer arms of the W by elastic pads bonded between them. This provides some elasticity for the bumper. An inner U-shaped insert inside the bumper bar is held on the bumper bar by fitting screws while the interior of the U profile is crossed by an array of shear pins. In the event of collisions greater than can be accommodated by the elastic pads, the central arm of the W profile progressively breaks the shear pins to provide inelastic absorption of the impact.

Title: Silicon carbide mfr. without sawdust furnace packing - partly-reacted reclaimed silica-carbon mixt. avoids blow-ups and bad odours
Inventor: MINEMURA YUJI
IPC: C01B31/36
Filed: 1974-04-08
Abstract: A mixt. of powdered SiO2 and carbon is pressed into pellets to give a min. apparent density of 1.0 g/cm3 and min. compressive strength of 6.5 kg/cm2; the pellets are then mixed with non-reacted or partly reacted reclaimed matl. as a furnace packing and heated in an electric furnace with a min. remaining air space of 10%. The reclaimed material comprises 50% SiO2, 30% C, 20% SiC, with particle size distribution 47.5% 9-1 mm sieve with 52.5% passing through a 1 mm sieve; the use of this material and the controlled density of the pellets prevents the blow-ups, smoke and bad odours from mercaptans, which arise when sawdust is used as a furnace packing.

Title: Infinitely variable gearing with eccentric speed regulating member - has spiral slots for control of radially movable elements
Inventor: DREIER KARL
IPC: F16H29/04
Filed: 1974-04-17
Abstract: The gearing has an input shaft and a disc displaceable radially in respect of the shaft axis. A rotatable output member concentric with the input shaft supports one end of an annular array of pivoted links whose other ends have spigots engaging respective slots in the disc. "Pistons" defined by arms pivoted at one end to the spigots while their other ends engage respective tangential surfaces on the disc. The slots extend spirally in respect of the disc axis and when the disc is moved into an eccentric position the slots cooperate, in addition to the tangential surfaces, to urge the arms sequentially towards, and away from the shaft axis. The result is rotation of the output member.

Title: Scanning of characters by columns - involves flying-spot scanner and preliminary and read scanning operations
Inventor: FISCHER BERND DIPL ING
IPC: G06V10/28
Filed: 1974-06-06
Abstract: In preliminary scanning carried out with the light spot travelling at a higher sweep velocity the height of the scanned character is established and stored. The character is then divided into segments which contain several image points in adjacent columns and/or rows, whose degree of density is derived from the scan signals and also stored. In the read scan operation carried out on the basis of the height of the scanned character, the scanning field is restricted, the sweep velocity of the light spot in the row direction is established and the threshold of an amplitude discriminator for digitising the scan signals is adjusted according to the degree of density.

Title: Mine support backfilling pack lagging sheet - side stiffener bars leave space for second sheet to clip in
Inventor: HACK KLAUS DR
IPC: E21D11/15
Filed: 1974-07-19
Abstract: lagging sheet for instant packing material used in backfilling behind supports etc. in the mining industry consists of a main sheet with parallel welded reinforcing bars and possibly with welded sheet stiffeners. The reinforcing bars terminate flush with the edge of the sheet on one side but on the other side stop short of the edge far enough to allow a second sheet of identical shape to be overlapped by a few centimetres. Preferably the weld on the bars should stop far enough from the edge of the sheet to allow the second sheet to be clipped in between the bar and the first sheet in overlapped condition. A strip should be welded into place lengthways and parallel to the round bars so as to end at the sheet edge using a weld at a distance from this edge sufficient to form a pocket to accept the clipped-in second sheet as specified.

Title: Application of colour to printed words - reduces eye-strain and helps to convey deeper meaning to reader
Inventor: FISCHER GERHARD
IPC: B42D15/00
Filed: 1975-03-12
Abstract: The invention concerns with the colour of the background of the page and the colours used for the individual words. The conventional sharp contrast between a white background and black printed words causes eyestrain. By the use of a light coloured background and different colours for different words, the strain on the eye is reduced since the whole of the colour sensitive rods of the retina are brought into use. By a correct choice of colours, the meaning is conveyed more easily to the reader.

Title: Flat high frequency band cable with small transverse conductivity - measures displacement between vehicles and uses discrete resistor modules
Inventor: SCHUCK WOLF-DIETER DR ING
IPC: H01B7/08
Filed: 1975-10-11
Abstract: The flat cable has two parallel conductors separated by a given distance, transmitting signals from a transmitter to a closely located receiver. The transverse conductivity of the cable is considerably smaller than the conductivity of the conductors. The cable (1) is used to measure the distance between two vehicles (2), which are provided with a transmitter coupler (3) a compensating coupler (4) and a receiving coupler (5). The transverse conductivity of the cable is determined by discrete modules. The module which consists of discrete resistors are placed at equal distances (17) apart.

Title: Attachment of heat exchanger tubes - incorporates damping material between tubes and holes of tube plate
Inventor: HEEREN HERMANN
IPC: B23P15/26
Filed: 1975-10-28
Abstract: The intermediate plates of a heat exchanger have holes of a larger diameter than the tubes which pass through them. A foil of pliable plastic material which has vibration damping properties is attached to the side of the tube plate from which the tubes are to be inserted. The foil originally has no perforations and covers the holes. Each tube has a conical nose piece with sharp edges. As it is pushed through the foil it cuts the latter and the circular pieces cut out of the foil are pushed into the gap between the tube and the hole in the tube plate. The foil material takes up the clearance between the tubes and the hole and dampens vibrations.
