Patent DE-3729065-A1 (DE)
Title: Fin with clamp fastening
Inventor: ROHR PETER
IPC: B63B35/79
Filed: 1987-09-01
Abstract: The present invention relates to a fin, in particular for a sailboard, with a guide section that can be inserted in a hollow section fastened to the sailboard, with at least one clamping element that can be inserted in a recess in the hollow section, and with at least one drawing element mounted on the guide part that engages with the clamping element. In known fins, the clamping element is located outside the guide part (4) on an indentation formed in the guide part (4). Such fins tend to break near the clamping element upon impacts on the fin. The invention is intended to make such a fin more stable. This problem is solved by the invention by the guide part having a bearing element constructed as a platelet to support the drawing element of the clamping device. <IMAGE>

Patent DE-3732592-A1 (DE)
Title: Control method and circuit arrangement for a bidirectional rectifier
Inventor: BERGMANN LUTZ DIPL ING
IPC: H02M7/797
Filed: 1987-09-28
Abstract: The bidirectional rectifier forms an uncontrolled DC voltage from a preferably three-phase mains voltage with the aid of six diodes, for example for supplying a drive converter. An electronically controllable switch (S1...S6) is connected in parallel with each diode (V1...V6) so that, in contrast to a normal rectifier, both current directions are possible. The switched-on phases of the electronically controllable switches are controlled as a function of the conduction phases of the associated diodes. During braking operation and energy-recovery operation, the switched-on phases are started at an advanced time (tb) before the natural turn-on time, in such a manner that the current (IS1...IS6) through the switch (S1...S6) to be disconnected has just become zero at the natural turn-on time. In consequence, voltage surges on the mains impedances are avoided, and the power loss occurring in a voltage limiter circuit (V7-ZD) is minimal. <IMAGE>

Title: Suction valve for compressed-air compressors
Inventor: CHURRUCA JOSE MARIA GOENAGA
IPC: F04B39/10
Filed: 1987-10-22
Abstract: In a suction valve for compressed-air compressors, an elastic plane closure flap or tongue is provided, which interacts with a seat surface in the form of a ramp, the inclined profile of which, diverging from the fastening point of the closure flap or tongue towards the free end thereof, moves away from this closure flap or tongue so that this closure flap or tongue comes into contact against the seat surface and closes the suction opening during the compression stroke of the piston in the cylinder of the compressed-air compressor only when the piston has at least virtually reached its normal operating speed, as only then is the throughput sufficient for bending the closure flap. The closure flap can be a single closure tongue, a double closure tongue or a disc-shaped closure flap, or have any other shapes.
Patent DE-3800086-A1 (DE)
Title: Container, in particular sales container
Inventor: NICHTS JUERGEN
IPC: A47F1/14
Filed: 1988-01-05
Abstract: In containers, in particular sales containers, it is known to provide retractable and extensible support feet for setting down the container in order to be able to lift the container from the transporting vehicle and, after removal of the transporting vehicle, to set it down on the ground. The support feet are actuated by means of a spindle drive which takes up a large amount of space due to the power transmission required and can only be actuated at great effort.   It is proposed that the vertical corner supports which connect the side walls, the container top and the container bottom to one another be designed to be hollow on the inside, that support feet be guided displaceably in the supports, and that a hydraulically actuable pressure cylinder be fastened in each case in the supports, the piston rod of which pressure cylinder is connected to the respective support foot.

Title: Combination lock with radiological detection resistance
Inventor: MILLER HARRY C
IPC: E05B37/08
Filed: 1988-01-07
Abstract: The combination lock comprises a lock case (21) and a stack of tumbler wheels (34-37) freely rotatable on a tumbler post assembly (22) which each include an outer rim portion (39) and an inner hub portion (38) having teeth (47,48). The teeth are releasably intercoupled to the hub portion and rim portion at any of a number of relative angular positions to permit combination change.  The rim portions (39) of the tumbler wheels have peripheral gates , but with only one true gate to receive a fence (44) on a fence lever (41) when the tumbler wheels are turned to their proper positions by a dial (26), drive spindle (27) and driving cam (32). The assembly is supported within the tumbler wheel hub portions for nonrotatable axial movement of a post (22b) to shift the hub portions axially relative to the rim portions between coupled and decoupled relation. A change key sector gear (57) is rotated by the change key to rotate a gear member (56) for axially moving the tumbler post and the tumbler wheel hub portions, to shift the hub portions to decoupled relation for combination change.  A secondary or combination change fence (65) is movable to interfit with the true gates when the proper opening combination has been dialed.
Patent DE-3811446-A1 (DE)
Inventor: ROEDEL GUENTHER DIPL ING
IPC: H01F7/06
Filed: 1988-04-06
Abstract: A device for producing a magnetic field by means of an electromagnet which can be switched on and off periodically in order to create a Zeeman effect to compensate the background absorption in an atomic absorption spectrometer contains a rectifier (216) for rectifying the alternating mains voltage, a regulated smoother (218) and transformer means (220) to the input of which a d.c. voltage from the smoother is applied. The transformer means (220) contain an electronic chopper (244, 248, 252, 256, 258) for chopping the input d.c. voltage with a frequency substantially greater than the mains frequency, a transformer (242) for stepping down the d.c. voltage chopped by the chopper and rectifying and filtering means (270, 272) for producing a d.c. voltage at the output. A switching device (402, 404, 406, 408) periodically switches on the output d.c. voltage to the electromagnet. This results in a more compact structure and reduced power consumption, and allows adequate time to carry out measurements with the magnetic field.

Title: Boring head with front cutters
IPC: B23B29/034
Filed: 1988-04-08
Abstract: Two blade carriers (3, 5) provided with a blade (4) are guided and held in a radially displaceable manner on the end face of a boring-head body (1). These blade carriers (3, 5) can be radially set by means of an adjusting device supported against an abutment and can be firmly clamped against a bearing surface by means of fastening screws (8) engaging in longitudinal slots (9). The bearing surface is a plane surface (22) in which a guide groove (10) running across the centre point is made. The two blade carriers (3, 5) each have a guide rib (11, 12, 13) guided in the guide groove (10). The width of the guide rib (11, 12, 13) is half as large as the width of the guide groove (10). A recess (14) reaching over parts of the adjusting device is made in the guide rib (11, 12, 13). So that the two blade carriers can be set quickly and precisely to a smaller or larger diameter, the adjusting device has two sliding blocks (15, 16) which engage in the recesses (14) in the guide ribs (11, 12) and are adjustably guided in opposite directions in the boring-head body (1) via a spindle drive (17, 18) mounted in a fixed position in the boring-head body (1). <IMAGE>

Patent DE-3839263-A1 (DE)
Title: Mechanical freewheel flywheel
Inventor: BAUMER ALFONS
IPC: F03G3/08
Filed: 1988-11-21
Abstract: For driving machines with a high starting torque requirement, use has hitherto been made of prime movers with a high energy consumption (gas turbines, steam turbines etc.). The use of such machines makes a continuous high energy consumption inevitable. When the freewheel flywheel is used for such driving purposes, the majority of the starting energy required is generated by the rotational energy of the mass of the accelerated flywheel. This results in a huge reduction in the energy consumption and the costs for such techniques.
Patent DE-3901318-A1 (DE)
Title: Highly concentrated acidic mixed products
Inventor: RUBACK WULF DR
IPC: C09K23/02
Filed: 1989-01-18
Abstract: It is desired, in order to save storage and transport capacity, to have available mixed surfactant mixtures whose content of active substance is as high as possible. Anionic surfactants of not more than 70%, and free-flowing mixtures of only 40% of active substance are known. The highly concentrated acidic mixed products are intended not to display these disadvantages and moreover be stable on storage for a long period and form no dioxane. For this purpose, mixed products consisting of paraffinsulphonic acid of the general formula R-SO3-H and alkyl polyglycol ether carboxylic acid of the general formula R'-O(AO)x-B-COOH are now proposed. The dry content of the mixtures is at least 70%, and the mixing ratio can be from 1:10 to 10:1. The mixtures are stable on storage and do not form dioxane. The highly concentrated acidic mixed products are used in surfactant solutions.

Patent DE-3907422-A1 (DE)
Title: Film closure with pouring and aeration hole for bottles
IPC: B65D47/32
Filed: 1989-03-08
Abstract: The commercially available glass and plastic bottles relevant in this case are, without exception, containers for liquids whose clear opening width is at least 1/3 of the internal bottle diameter, such as is observed, primarily, in bottles for motor oil, antifreeze and juice. The bottles used, in particular, in the case of contents which are hazardous to the environment are too complicated for the layperson with their oversized pouring openings because they do not guarantee emptying without spillage. The sufficiently known problems are convincingly counteracted by a subdivision into a larger (4) pouring opening in the film closure and a smaller (5) air opening in the film closure. The previously customary practice of having to tear off the film closure bonded at the edges (3) to a greater or lesser extent is now counteracted by sensible openings being present which allow even a layperson to undertake controlled emptying and are compatible with the requirements for reinforced and more responsible environmental awareness. <IMAGE>
