Patent DE-2400193-A1 (DE)
Title: Demagnetising of large ferromagnetic work pieces - uses LF pulse groups of alternating polarity with alternately increasing and decreasing amplitude sequence
Inventor: AICHELE GERD
IPC: H01F13/00
Filed: 1974-01-03
Abstract: The demagnetising process is intended for large ferromagnetic workpieces which are exposed to a slowly decreasing magnetic A.C. field strength by decreasing the magnetising current and/or by increasing the distance between workpiece and magnetising coil, whose frequency is smaller than the mains frequency to achieve sufficient depth of penetration. The magnetising current is a low frequency pulse or gap current composed of pulse groups of alternating polarity, the intensity of which slowly and monotonously decreases, and where in each group the intensity of first increases and thereafter decreases and the envelope of which may be sinusoidal or triangular. The demagnetising of a large ferromagnetic workpiece is achieved by that the pulse groups of one polarity are suppressed.

Title: Door stop for motor vehicle - has flexible wedge shaped brake which engages with steps in spring
Inventor: FREUDENBERGER ALFRED
IPC: E05C17/20
Filed: 1974-02-14
Abstract: The door stop is used for limiting the opening movement of motor vehicle doors and also holds the door in a predetermined open position. The door stop has braking wedges which are held in a fixed housing. The wedges have a sliding contact surface and these wedges are arranged symmetrically on either side of the symmetrical stepped locking profile made from flat spring material. The locking wedges match the step profile. The wedges have rubber cores for ensuring spring action and these wedges prevent excessive swinging out of the door and the wedge pressure ensures smooth opening movement and positive braking at the steps. No excessive force is used in initial opening of the door and positive force is used in later stages.

Title: Section warper for larger dia. beams - stable at very high speeds, easily accessible for service
Inventor: WILDI EDWIN
IPC: D02H3/00
Filed: 1974-02-27
Abstract: The design of a typical section warper is modified to give much easier access when drawing in from the creel and picking up broken ends. The side frames supporting the reel driving shaft are extended upwards and tied with cross beams to give a height beneath the traversing feed beam of at least 180 cm. The section reed and traverse guide are suspended downwards from the feed beam. Access to the face of the warp is much easier and the working zone is constantly illuminated by a lamp moving with the feed beam.

Title: Extrusion of structural foam (esp. polystyrene) articles - using bypass to permit withdrawal and recirculation of excess material
Inventor: SCHERER HEINZ
IPC: B29C44/42
Filed: 1974-03-07
Abstract: In the production of mouldings of structured foam by the injection of a mass of thermoplastic material whilst the expanding agent is active, under a pressure greater than that of the gas in the mass, into a tool in which foaming can take place; the form tool into which compressed air may be pumped to prevent premature foaming, is first filled from the plasticiser. The pressure is then reduced to below that of the expander gas, so that, as the foaming develops, the excess material is withdrawn from the mould with the plasticiser outlet valve closed, and densified as it is returned round the by-pass into the plasticiser cylinder. Fully-foamed, smooth outer surfaced structures of the desired specific weight are obtained without expensive and complicated moulds.

Title: Pyrolytically cleaned oven door safety mechanism - with single component simultaneously locking door and switching on heating element
Inventor: GRESSE ROLAND
IPC: F24C15/02
Filed: 1975-06-26
Abstract: The purpose is to ensure that the door on a roasting oven cannot be opened while the interior temperature is above a predetermined level. When the single actuating components is in the operative position, it locks the oven door and switches on the current supply to the heating element keeping the locking action in force as long as the temperature is excessive, and releasing it only when the component is returned from the cleaning position to any other position that is chosen. The locking action is by a bolt turning about a horizontal axis and penetrating a slit let into the door working against a tension spring, with the bolting rod activated by a spring in the locking direction and by an electromagnet in the unlocking direction.

Abstract: Parent Patent describes a process for structurising proteins by co-pptn. of (1) water-contg. proteins which separate serum on heating with (2) water-contg. syneresis-free coagulating proteins, esp. albumins and globulins. Now the albumin- and globulin content of membrane filter concentrates is made better use of by co-pptg. the albumins and globulins with casein. Milk protein concentrates prepd. by membrane filter processes, e.g., ultrafiltration, reverse osmosis, gel filtration or electrodialysis, contg. non-coagulated whey proteins in addn. to casein, are mixed with water-contg. e.g., colloidal, or dried albumins and/or globulins. The natural ratio casein:alumins + globulins is increased from 85:15-80:20(70:39) esp. 50:50 or more. The protein mixts. or food compsns. contg. them, are heated, without stirring, in moulds or packs, to 75-100 degrees C. Heating time depends on size, and may be 15-60 mins. The food prods. can be cut, cooked and fried.

Title: Radially and axially adjustable tyre assembly drum - has central section comprising stacks of spring-loaded plates
Inventor: ROST HARRY
IPC: B29D30/24
Filed: 1975-11-14
Abstract: The assembly drum comprises end cylinders of variable dia. made up of radially adjustable segments and a centre section made up of segments which follow the same radial movement. The segments are mounted on interconnecting guides which join the end cylinders together, and are thus constrained to move radially (for changing the dia.) with the end segments. The segments of the centre section are elastic plates, sliding on the guide tubes and held apart at equal intervals by compressed spring cartridges. The drum is esp. for use in small factories. To change to a different drum size for a different size (radially and axially) of tyre, no changing of parts is necessary. The operation takes only a few minutes.
