Patent DE-2431748-A1 (DE)
Title: Razor blade packaging equipment - composite plastic and metal razor blades stacked in container
Inventor: BAILEY JUN DAVID CROWELL
IPC: B65B25/00
Filed: 1974-06-28
Abstract: The blades are inserted by an apparatus which receives them side by side and transports them using a transfer head to a supporting surface on the loading platform. A second transfer head moves to and fro in relation to the loading platform and carries a container to the articles grouped on the platform so that the blades partially enter the compartments of the container, elements then coming into contact with them to push them into the compartments where they are automatically locked. The elements consist of pegs which project from a common plate and pass through corresponding apertures in the platform when the plate is moved.

Abstract: A device for generating in a discharge tube, fitted with a thermoemitting cathode and filled with mercury and argon, ultraviolet radiation of high spectral density, the stabilised gas discharge occurring at a press. PHg of the mercury between 5.10-3 and 5.10-1 Torr., and at a flow density j of the discharge stream I between 1 and 25 A/cm2 has a discharging tube provided with a press. levelling chamber connecting the cathode chamber to the anode chamber, the vols. of which together are greater than the vol. of the discharging chamber. The press. of the argon PA lies between 0.01 and 10 Torr. Two control organs are also fitted, a first raising the flow density j to a constant value jo between 1 and 25 A/cm2, and a second organ raising the press. PHg to such a level that the yield at a wavelength of 2537 A relatively to the electrical energy fed in, amts. to at least 80% of the max for the adjusted flow density jo. The special dimensions of the anode, cathode and press. balancing chambers relatively to that of the discharge tube, prevent plasma vibration and ensure stable operation. Uniform press. of the discharge medium makes ignition of the discharge tube by simple means practicable. Device is useful e.g. for sterilisation of food packages or powders.

Title: Pipe coupling for connecting pipes under pressure - fluid retaining diaphragms will burst as joint is made
Inventor: GRUBER WALTER
IPC: F16L29/00
Filed: 1974-11-09
Abstract: The pipe (R1) is soldered to a screwed fitting (1) which receives the coupling nut (3). The pipe (R2) is soldered to the fitting (5) which is pushed inside the fitting (1) by the action of the coupling nut (3). A diaphragm (7) is soldered inside the fitting (1) and a similar diaphragm (8) is soldered over the end of the fitting (5). These diaphragms have radial grooves forming lines of weakness so that when the coupling nut (3) is tightened the diaphragm (7) will burst and the petal-like segments are deformed outwards to lie against the inner surface of the fitting (1). The diaphragm (8) is then fractured in a similar manner without any leakage occurring as the joint is finally tightened.

Title: Height adjustable leg for furniture - is engaged by threads in outer connecting sleeve which absorbs distortional forces
Inventor: MOECKL ERNST
IPC: A47B91/02
Filed: 1975-01-20
Abstract: Theheight-adjustable leg for furniture or machines comprises a threaded cylindrical support member which, by means of its outer casing face, positively engages for rotational movement in a sleeve. This sleeve forms the connecting element which on one side is connected to the part (9) of the furniture to be supported and on the other is connected to the support member by its mating thread. Should any distortion forces occur which may bear on the connecting element they are taken up by the stable sleeve which has a relatively large surface area where they are transferred to the furniture.

Title: Swivelling handle for pan - has compression spring locking handle in range of positions, and resetting slide
Inventor: NORRA WOLF DIETER
IPC: A47J45/06
Filed: 1975-02-26
Abstract: The swivel pan handle is fastened by a segment pivoted on a spindle between a holder on the edge of the saucepan so that it can be swivelled up and down about this segment relative to the pan. The segment fits into a fork in the handle and a hole is drilled in between the two arms of the fork so that a bolt, compression spring and a centrally-bored threaded screw can be fitted, to secure the handle. The peripheral edge of the segment is provided with blind holes so that the compression spring can lock the bolt in any of these holes to fix the handle in different positions. A slide can be incorporated in the handle so that the bolt can be retracted to allow displacement after which it is resest by the spring pressure. The pan handle can be folded up out of the way as required and can also be set in the optimum position for carrying the loaded saucepan.

Title: Submersible offshore drilling platform - assembled in bolted sections during successive immersion and by welding during floating
Inventor: KNABE STEFAN
IPC: E02B17/02
Filed: 1975-03-12
Abstract: An offshore drilling platform is produced by connecting three submersible foundation tanks to a triangular base on which the inclined legs of a tripod and a vertical centre tube are erected. All sections of the legs and centre tube with their truts are bolted together as the foundation tanks are flooded and submerged successively deeper. When the top joint of the tripod has been reached, it is welded on and all bolted connections are replaced by welding through floating the structure upwards in stages. The submersible platform produced in this way is much cheaper and can be completed in a much shorter time than conventional designs.

Title: Control circuit for battery state indication - has current supply path with pulse feedback in signal frequency rhythm on high ohmic battery state
Inventor: GERUM ERICH
IPC: H01M10/48
Filed: 1975-07-03
Abstract: The control circuit is particularly intended for an alarm clock battery and uses a pulse generator for actuating a control transistor. With the battery attaining a high ohmic state, the pulses appearing in the rhythm of the signal frequency are fed back in such manner that a time changing effect is produced at the previous stages. Preferably the pulse generator is of astable type and is affected via a capacitor, while the control transistor may be also energised directly. The transistor may be biased and may be energised at its base via a capacitor connected with the supply line.

Title: Torque transmitting universal coupling - has three spherical rollers mounted on needle bearings with biasing springs
Inventor: SCHMID LEOPOLD F
IPC: F16D3/205
Filed: 1976-01-08
Abstract: The transmission of torque is carried out by means of three rollers (3) which are equally spaced along the circumference of the coupling. The rollers have spherical surfaces (4) and are mounted with needle bearings on three studs (2) in such a way that they can rotate and move radially outward. The three studs form part of an inner coupling. The rollers can slide axially in three grooves (9) in the outer coupling. The grooves are parallel to the centreline of the outer coupling. When the rollers are displaced axially during rotation, the accompanying radial outward movement is introduced by springs (6) which are mounted inside the rollers and against the ends of the studs. The springs push the rollers against the surfaces of the grooves.
