Patent DE-2113628-A1 (DE)
Title: Supporting injection mould core - with movable support at opposite end from core mounting
Inventor: WAIBLINGER FRIEDRICH
IPC: B29C45/36
Filed: 1971-03-20
Abstract: An injection mould for making closed or open hollow rubber or rubber-like plastic objects, e.g. bags, bellows, sleeves or coverings for moulded objects has a core projecting into the mould and fixed to one of the mould components and supported from other components. The supporting mechanism comprises one or more movable abutments, which can be withdrawn from the mould, and which fit tightly against the core. Prefd. the abutment is a sliding fit in a hole in the mould at the opposite end from the fixing point of the core, and engages a corresp. recess in the end of the core. The injection duct enters the mould in this region, so that the abutment can be used to stabilise the core throughout the injection operation, except for the final portion for closing the moulding completely; to complete this final portion, the abutment is fully withdrawn.

Title: Mass-produced orthopaedic shoe - insert closely matches shape of foot
Inventor: BOLL ERNST
IPC: A43B7/14
Filed: 1973-07-09
Abstract: A first last is made which has a tread corresponding exactly to the shape of the deformed foot and then an inlay is made from the shape and size of the tread of this first last. A second last is then made from the first last together with the inlay and this second last represents the shape of the inside of the shoe taken from the first last and inlay so that the orthopaedic shoe can be made from the second last. The inner shape of the shoe need not correspond exactly to the shape of the deformed foot since it is the inlay which forms the actual properly shaped support for the deformed foot and therefore the shoes can be mass-produced. The inlay widens wedge-shaped behind the ball of the foot to form a support for the foot. The inlay is preferably of cork which provides a firm yet resilient support.
Patent DE-2336894-A1 (DE)
Title: Electro-optical delay cct. with phototropic glass between transducers - has its intensity-induced transparency changes to provide delay
Inventor: STABER FRIEDRICH
IPC: H01H43/00
Filed: 1973-07-19
Abstract: The electro-optical delay circuit consists of an electro-optical transducer, e.g. a light emitting diode, and an opt-electrical transducer, e.g. a photodiode, phototransistor, photoresistor or photothyristor. A piece of phototropic glass is placed between the two transducers so that its delayed response in transparency to changes in the light emitting diode light intensity acts as the circuit delay. Since the delay between changes in the phototropic glass transparency is somewhat large, the delay circuit is suitable in cases where longer delays are required. The phototropic glass may act as lens focussing the light onto the phototransistor.

Title: Absolute oxygen-content determn. of water - by comparing percentage result with satn.-value obtd.
Inventor: HOEHN ALFRED
IPC: G01N33/18

Title: Hand operated carpet sweeper with non-electric drive - can be readily adapted to apply carpet cleaning material
Inventor: MUSCH EBERHARD DIPL-ING
IPC: A47L11/34
Filed: 1973-08-16
Abstract: The carpet sweeper has twin rotating brushes driven by pinions from the support wheels. By pressing the disc the rods push the pinions against the springs and out of engagement with the support wheels. Also the dust collecting box is pushed to one side so that the cleaning medium can be brushed into the carpet without being forced back into the dust-box. Other forms of the invention apply to single brush cleaners without a dust collecting box. In this case, the cleaner housing has longitudinal flaps which can be retracted to facilitate the brushing in of the cleaning medium.

Title: Pan lid preventing boiling-over of liquids e.g. milk - has superposed lids with holes
Inventor: HUTZELMANN HEINRICH
IPC: A47J27/56
Filed: 1973-11-13
Abstract: Device prevents boiling-over of liqs. e.g. milk and consists of a pan lid in which are holes and a further lid with holes, above the first. Each lid is a combination, according to the purpose of the application, and to ease of mfr., of planar, upward (convex), and downward (concave) curvatures. More partic., sudden strong supply of heat cannot cause boiling over of the liq., and the upper lid can be conveniently curved upward, leaving no edge to trap the liq. flowing down. Conventional lids are used, solely with holes, to produce the device without special tools being needed for mfr.

Title: Stabilised independent suspension for driven wheel - with axle stub mounted on axial and vertical elastic bearings for asymmetric toe in
Inventor: STOTZ ERICH
IPC: B60G3/20
Filed: 1974-04-05
Abstract: The axle stub of the independently sprung rear wheel is connected to the suspension member by a horizontal bearing pin mounted between two elastic bearings. One bearing is further attached to the frame member by a tag which is pivoted on the frame about a vertical axis. This gives the suspension an asymmetric characteristic, especially when the bearings are different. The wheel is usually moved in a vertical plane, except during cornering in which the toe-in varies with braking and drive forces to achieve the optimum amount of understeer.

Title: Fire resistant door - self-supporting stepped filler plate enclosed by door leaf frame edges
Inventor: WEDEL ERNST VON DR ING
IPC: E06B5/16
Filed: 1974-04-20
Abstract: The DIN standard requirement for acceptance of fire resistant doors is that on the side away from the fire, along a strip of 10 cm width, the temperature increase should not be found in acceptable. The arrangement is designed to contain any heat build up on the side of the fire by making the door leaf of non-conducting material and shaping the edges of the sheet metal leaf frame so that again it has contact only with non-conducting surfaces. By designing the non-conducting panel in a stepped fashion, it heats up unequally, hereby counteracting a possibility of internal stresses. The non-conducting door panel can be designed as a laminated construction.

Title: Parallel signal transmission method - uses multiple frequency method for speech, data and dialling signals
Inventor: FUCHS ERNST DIPL ING
IPC: H04M11/06
Filed: 1974-05-17
Abstract: When a sender is switched over to a higher speed data transmission, the speech circuit is disconnected from the line, and a first signal is transmitted to the receiver, where a signal is derived from it which makes a speech protection circuit inoperative. When data transmission is restarted at a lower speed, the speech circuit is connected to the line and a second signal is transmitted to the receiver which restores the transmission circuit's original operation. A signal, derived from the first signal transmitted to the receiver, sets the distortion correction circuit for received signals to the changed transmission.
