Patent DE-2344979-A1 (DE)
Title: Flange closure for igniter housing - has shoulder bent round inwards to press cover against conical step
Inventor: HUEBSCH GUENTER
IPC: F42C19/08
Filed: 1973-09-06
Abstract: The flange closure for a housing of an igniter for a propellant charge, has the wall near the opening to be closed cylindrical in shape. A cover spans the opening, and has the internal cross section of the cylindrical wall, before flanging, widened by a conical annular step and an adjoining shoulder toward the opening. After flanging, the shoulder, which is bent round inward, presses the laid-in cover against the conical step. Preferably the cover, before flanging, is planar, with an outer dia. equal to, or only slightly less than, the max. dia. of the conical allular step. The flanging process produces a secure seal.

Title: Nougat cream bread spread - is made using a milk protein powder having a high albumen and globulin content
IPC: A23L33/115
Filed: 1973-09-06
Abstract: A pasty spread for bread is made by treating natural substances prepared in known manner, e.g. nuts, vegetable fats, sugar and cocoa, with a milk protein powder having an increased albumen and globulin content. The nutty aroma is not lost in prodn. so that addn. of nut oils, previously necessary when using skimmed milk in the process, is obviated. Milk protein powder gen. contains 0.7-0.8% albumen and globulin: this amt. is pref. trebled for the present process. It may be produced by spray-drying a 1:3 mixt. of fresh skimmed milk and fresh cream.

Title: Split bush connector socket for single pin short-circuiting - uses two opposing half-cylinder bushes with insulating gap
Inventor: DIERINGER LORENZ
IPC: H01R13/703
Filed: 1973-10-06
Abstract: The connector socket for an electrical short-circuiting plug consists of an insulating cylindric body and a single bush with two insulated electrical conductive components which bound mechanically together form a centre opening into which a banana plug can be inserted to produce a conductive connection between the bush components. These can be two cylindrically shaped metal parts which in one end-region are fixed to the insulating body so that may have on its inner walls remain free. The insulating body may have on its inner walls two symmetrically arranged half circle slots which accept an extension piece of the bush components. At the ends spaced from the insulating body the bush components may have a larger wall thickness than the remainder to facilitate external connection.
Patent DE-2351789-A1 (DE)
Title: Recording system for transmitting electricity meters - with selective recording to reduce paper requirements and an encoder to store measured valves
Inventor: HOFFMANN HORST
IPC: G01D4/00
Filed: 1973-10-16
Abstract: The system employs a single printer and/or punch unit to record measured values from transmitting electricity meters. Each meter has an encoder to store the measured values. The encoder outputs feed into a common data bus connected to an interrogation control unit from which address lines lead to the individual encoders. Switches connected to the encoders and the control unit regulate the recording programme so that the printer/punch records either all measured values or only maximum values or only values occurring in given measuring periods. By recording only selected values, the amount of paper needed by the printer can be kept small even though it is connected to a large number of meters.
Patent DE-2361272-A1 (DE)
Title: Protector to avoid damage to seals - for use with conveyors moving polymerising liquids fitted with intermediate protective section between rotor and seal
Inventor: HUENING WERNER DIPL ING
IPC: F04D29/10

Abstract: The method is for avoiding agglutination and damage to lubricating seals of conveyor installations moving resin or polymerising liquid media. An additional protective intermediate piece is fitted between the conveyor rotor and the seal into which at least one level sensor with one gas inlet and gas outlet are built in. The level sensor controls a regulating switch for the supply of an inert gas into the intermediate chamber regulating the level of the liquid at that point. A long shaft connects meter and rotor which runs right through the intermediate section making it possible to convey media at high temperatures.

Title: Output limiter for combustion engine - switches off electrical loading of engine driven generator after preset time over max
Inventor: MERKEL HEINRICH
IPC: H02H7/06
Filed: 1974-03-13
Abstract: After exceeding the maximum output by a given, allowable time, the electrical loading of the generator is reduced and/or switched off. An electrical measuring transformer is built into the generator circuit and is effectively connected with a undelayed limit valve switch. On exceeding the continuous output of the combustion engine this switch switches in a timing switch mechanism and/or interval measuring mechanism. After exceeding a maximum allowable time, added or measured from part times, the timing switch mechanism operates a warning system and or sequence circuit to reduce and/or switch off the generator loading. After expiry of the operating interval, the interval measuring mechanism resets the timing switch mechanism to 'zero'.

Title: Apparatus for continuously welding thermoplastic film - with inductively heated wire guided in roller system to welding position
Inventor: HINTERSEER HEINZ
IPC: B29C65/02
Filed: 1974-07-09
Abstract: Parent patent describes an appts. for continuously welding thermoplastic film which has a heated wire guided in a roller system to the welding posn. In this addn. the heat required for plasticisation is provided by a roller-guided, inductively heated, endless metal wire, which may be blank coated or partly coated, and have a round, flat, oval or polygonal section. The film is led over the surface of a rotating roller, and the heated wire is guided over the film, and pressed radially in a frictionless manner onto the film by its own tension, so that welding is effected at a similar angular velocity of the wire, film and surface of the roller. Heating can be effected by an induction coil immediately before the wire is pressed onto the film. Heating is thus effected any contact with the wire, and this can be more accurately guided.

Title: Mechanical press with two brakes - which can be operated separately
Inventor: BRANDSTETTER RUDI
IPC: B30B15/28
Filed: 1974-11-14
Abstract: The two brakes are used to brake the movement of the main drive shaft. One of the brakes is used during normal operation of the press, while the other brake is in the form of an auxiliary brake. Both brakes can be lifted against the action of brake operating springs, by means of a pressure medium. The brakes can be operated separately by releasing the pressure medium. The press has an arrangement to balance the weight of the ram by the pressure of an air-cushion. The cylinder of a cylinder-piston unit is connected to the frame of the press, while the piston is connected the ram. A minimum limit pressure switch is connected to the air cushion in the cylinder. This switch operates the auxiliary brake when the pressure of the air cushion is too low.

Title: Clamp for connecting furniture components - has end tabs fitting in grooves in each bevelled corner panel
Inventor: HEGGER GEORG
IPC: F16B12/46
Filed: 1975-03-18
Abstract: The clamp (1) is L-shaped with two limbs (2) of equal length and is usually made from spring steel. The ends of the legs of the bracket are bent over at 90 deg. forming short protrusions (3) which point inward. When two bevelled ends of furniture panels are placed together, the clamp is fitted in grooves near each edge and extends around the corner. The short protrusions fit into grooves at right angles to the surface of each panel. Alternatively, the clamp can be placed in holes drilled in the parts to be connected so that the clamp is invisible from the outside. In that case, spring strips are used to keep the clamp in position.
