Patent DE-2412404-A1 (DE)
Title: Bag filter cleaned by compressed air - through rotatable distributor box with solenoid-actuated disc valves
Inventor: WALTHER PETER
IPC: B01D46/00
Filed: 1974-03-15
Abstract: A bag filter with a large number of tubular bags, arranged in concentric circles, is separated by a partitions in a dust-laden and a pure air compartment. The dust-laden air passes through the bags in the direction from the outside towards the centre. To clean the bags, compressed air is admitted in the reverse direction through a rotatable distributor box above the partition, with solenoid-actuated disc valves which can be aligned with one open end of a bag at a time. This makes at any time only one bag out of the total number inoperative for the duration of the cleaning process. This raises the utilisation factor of the filter. The cleaning operation is simple to control and can be readily automated.

Title: Pivot pump tube communicating with coaxial outlet pipe - has means for separating higher density materials from pumping fluid
Inventor: ERICKSON JOHN W
IPC: F04D1/12
Filed: 1974-04-23
Abstract: Pivot pump for conveying liquids with undesirable materials of higher density comprises a cylindrical rotary housing with an annular pumping chamber and an annular outer wall on which the higher density materials are deposited, and a stationary Pivot tube extending radially into the chamber with an inlet near its free end which is radially offset from the outer wall towards the chamber interior and which points in the opposite direction to that of the liquid. The interior of the pivot tube communicates with an outlet pipe coaxial with the housing. In the outer wall are openings of sufficient dia. to allow materials contained in the liquid to leave the housing, but with a smaller total cross-section than the inlet opening, to prevent pressure from falling than the inlet opening, to prevent pressure from falling in the outer region of the chamber during rotation of the housing.

Title: Flexible electronic circuit carrier with conventional wiring - which can be folded up has slits through which wires may be pushed
Inventor: LEHMANN KARL-OTTO PROF DR
IPC: H05K1/02
Filed: 1974-05-13
Abstract: The flexible carrier device for electronic circuits is used in small quantity or experimental work where the finished circuit has to take up a small space. A flexible insulating sheet or film has slits (2) in specific places through which the connections on the circuit elements can be pushed. Connecting up is performed with the aid of conventional wiring on the opposite side of the film. The insulation is also provided with preformed folding lines (3), which may consist of lines of perforations. On completion the circuit can then be folded up along these lines and is held in a suitable carrier. The slitting (2) may be unidirectional or on crossing diagonals, and is typically separated by blank areas to allow space between folds.

Title: Furniture hinge with height and sideways adjustment - has two eccentric adjusting screws and edge extension for sideways adjustment
Inventor: GRASS ALFRED
IPC: E05D7/04
Filed: 1974-07-19
Abstract: A fixed baseplate is on one side wall with a U-shaped bracket connected to the baseplate slots and this bracket is also connected by means of a pivoting hinge to a support in the doorpanel. The door panel can be adjusted in mutually perpendicular directions upwards and also sideways. The door need not be supported or held and no danger of tilting or rocking of the door will occur. The baseplate (2) has at its end, near the door, a projection which partly covers the narrow edge of the wall. This projection supports an adjusting screw contacting the U shaped bracket (11), which has a longer arm on the hinge fixed part on the wall. Adjusting eccentric screws (7, 8) are in the hinge plate for height adjustment. The sideways adjustment is carried out by the adjusting screw in the projecting part. The hinge half in the door is held firmly by a dish-shaped sunk seat.

Title: Folding watertight container for flowers - has cardboard walls protected by bag from damp
Inventor: ORTH GEB EUTENEUER GERTRUD
IPC: B65D33/02
Filed: 1974-08-05
Abstract: The walls of the folding container are preferably of printed cardboard, and are fully protected from damp all the way round by a bag of sheet material. It can be so arranged that on opening a vacuum is generated inside, pulling inwards the protruding pockets of the bag, and forming a double skin at top and bottom. Depth can be varied by sliding the folded walls inside the free spaces in a pocket of sheet material. There can be a double bottom, so that if the first one is inadvertently punctured the second one will prevent escape of fluid. By grooving the walls these can be arranged to fold at various positions so that the base automatically matches the shape of the container.
Patent DE-2443184-A1 (DE)
Title: Milling machine unit - consists of three machines each built from standard parts arranged to operate in sequence
Inventor: WUESTNER HORST
IPC: B23Q37/00
Filed: 1974-09-10
Abstract: The three milling machines are arranged around a rotating table. The work is loaded and unloaded at station, is machined by the horizontal miller at station, is machined by the vertical miller at station and finally machined by the vertically mounted cutter at station. Each milling machine is built from the same standard parts, but mounted so that each slide moves in a different axial direction. The standard parts are, the base unit with guide rails, the traversing drive, the milling cutter spindle housing the end plate and the extension piece. This arrangement permits more intensive use of machines made from standard parts.

Title: Door locking mechnsm. for transport containers - has locking rod for ensuring sufficient force for opening frozen doors
Inventor: BURKERT MAX
IPC: E05C9/02
Filed: 1974-10-03
Abstract: The door locking mechanism is used especially for goods transport container walls and it has a longitudinally sliding locking bar. This locking system is flat and compact a and its locked state can be recognised even in poor light. This lock cannot be locked inadvertently and it can be opened when door seals are for example frozen together. The lower and upper end of the locking rod (4) of the door act as locking elements. The upper end is bent sideways and forms a T or hook shaped lock (6). An actuating lever (10) is held on the lower support (2) by a universal joint. The shorter end of this lever acts as an actuator which engages with the locking rod corresponding seat (16) after rotating. The locking or opening sliding movement is transmitted to the locking rod subsequently by a vertical rotating movement of the actuating lever.

Title: Shunting system for railway wagons - uses linear motored shunters with reversing turntables operated using braking energy
Inventor: ASSMUS ALFRED DIPL ING
IPC: B61J3/00
Filed: 1974-11-04
Abstract: The linear motored shunter (4) runs on a haulage track (8) running parallel to two neighbouring railway tracks (1) to push, by means of a projecting roller, (11b) contacting the rear wheel running surface of the wagon to be shunted, a certain distance along the track. The shunter is then turned round by turntables (12a) arranged respectively at each end of the rail running parallel to the first track. The linear motors and the turntables are regulated by a central control system in the sense that the shunters kinetic braking energy is translated to the turntable rotating energy and the turntable braking energy is translated to the shunter.

Title: All year heat pump installation - operates with freezing water by extracting latent of fusion
Inventor: SCHRAMMEL HUBERT
IPC: F24V50/00
Filed: 1975-11-22
Abstract: The heat-pump installation operates all the year round, extracting heat from freezing water in water as efficiently as from warm water in summer. It copes with the period when ice crystals are beginning to form in liquid waters by discouraging their formation close to the evaporator: (a) by covering it in a suitable sheathing material, (b) by keeping the temp. at the evaporator surface high enough for the ice crystals to form elsewhere and (c) by pulsed pumping of the refrigerant to produce temp. fluctuations at the evaporator. To cope with such ice as does form, the evaporator's smooth surface is divided into small areas by a criss-cross of heat-insulating ribs, so that ice comes off easily in small flakes. The warmth contained in the refrigerant is used for the de-icing.
