Title: Suspension of a supporting hook
Inventor: WALDHAUSER FRANZ
IPC: F16B5/07
Filed: 1987-12-03
Abstract: The invention relates to suspension of a supporting hook so that it hangs into a vehicle body side which delimits a humid chamber, in the case of which the supporting hook can be partly inserted through a hooking-in aperture which is cut out of the body side and can be transferred, in the course of a backwardly directed feed movement while suspended, into a supporting position which grips from behind a hooking-in edge of the body side. In order to prevent the emergence of water through the hooking-in aperture, provision is made for a section, which is situated above the hooking-in edge, of the body side opposite the hooking-in edge to be offset in the direction of the depth of the humid chamber in such a way that water running down the humid chamber side of the body side above the hooking-in aperture is diverted downwards around the hooking-in edge and the suspended supporting hook.

Filed: 1987-12-07
Abstract: According to the present invention, provision is made for a spraying unit for a rolling mill which comprises: a spraying pipe with a pipe branch for conveying liquid to be sprayed out; spraying nozzles which are arranged along the spraying pipe and are connected via channels to the pipe branch; and in each channel a fluid-operated valve which is arranged in order to control the flow of the liquid to be sprayed from the pipe branch to the spraying nozzle, the valve containing a closing part which is movable between a closed position, in which the flow of liquid to be sprayed is cut off, and an open position, in which the flow is permitted, and which spraying unit is characterised in that the closing part has a sealing section which is carried on a variable projection-supporting wall, the sealing section and the carrying wall together forming a pocket into which the valve-controlling fluid can be introduced in order to retain the closing part in the closed position, in which the sealing part cuts off the flow through the channel, and the closing part can be moved from the closed position when the supply of controlling fluid is removed, in which case the projection of the supporting wall is reduced and the sealing section moves from its closed position.
Patent DE-3743709-A1 (DE)
Title: Drainage pump, in particular for washing machines and dishwashers
Inventor: HUBER HEINRICH
IPC: D06F39/08
Filed: 1987-12-23
Abstract: Known drainage pumps are equipped with open impellers which are spaced apart from the pump-housing walls by large distances. Consequently, deposits of foreign bodies are avoided and the latter are delivered into the discharge system of the washing appliance. This open structure, however, results in undesired turbulence and secondary water channels in the pump housing, which impair the delivery performance. Pumping-away takes place in programme-controlled steps. The pump housing can fill with water independently during the stoppage times. In the case of the drainage pump according to the invention, use is made of a closed pump wheel which fulfils all special requirements for use with washing appliances. It is possible to shorten the programme-running time. A rotatably mounted L-shaped pipe piece (16) equipped with blades (14) projects, with its inlet cross-section (F1), into the intake connection stub (2) of the pump housing (1). Large radii of curvature (12'), (12'') allow foreign bodies to slide out of the discharge connection stub (3) unobstructed during pumping-out. The novel drainage pump is suitable for use in washing machines and dishwashers. <IMAGE>

Patent DE-3804549-A1 (DE)
Title: DC motor which has no commutator but has a permanent-magnet rotor
Inventor: SCHMIDER FRITZ
IPC: H02P6/14
Filed: 1988-02-13
Abstract: Hall ICs are used as a rule as the rotation-position detectors in DC motors which have no commutators. These Hall ICs signal the rotor position and accordingly cause current to flow through the winding in a pulsed manner. However, such detectors are highly temperature-dependent and are therefore too unreliable and too costly for some applications. For simplification and for reliable operation of such motors, it is proposed to use an induced auxiliary voltage, which is produced by the rotor movement, for controlling the pulsed flow of current through the power winding (main winding) (19). <IMAGE>

Title: Method of driving a tubular, underground cavity, in particular at a great depth, as well as apparatus for carrying out the method
IPC: E21D9/06
Filed: 1988-06-28
Abstract: In the driving of a tubular, underground cavity (1) at a great depth by means of a driving unit (3) which has tools for excavating the rock at the heading face (5) in the front area of a shield casing (4) absorbing the rock pressure, a pasty material (15) with a low internal coefficient of friction is injected into the annular space (16), limited to the inside by the shield casing (4) and to the outside by the wall (13) of the driven cavity (1) and closed off towards the heading face (5) and to the rear, and is held in the annular space (16) in a pressure state selected as a function of the rock pressure. This material, conveniently a mixture of a clay material, such as, for example, montmorillonite and water, behaves like a solid in the annular space and is thus able to transmit the rock pressure to the shield casing (4) but has a very small angle of internal friction so that the driving forces exerted by the driving jacks (9) are largely independent of the rock pressure. During the driving, a sliding surface (17) forms in this material so that seizing of the driving unit (3) is prevented even after prolonged stoppage. <IMAGE>

Patent DE-3823860-A1 (DE)
Title: Process for the repeated use of a metal sheet of a shuttering for series-produced precast concrete compound units with different arrangements of installation parts
IPC: B28B7/02
Filed: 1988-07-14
Abstract: In shutterings for series-produced precast concrete compound units, for example for switch sleepers, the shuttering metal sheets serve simultaneously as a template for the position of the installation parts. The shuttering is usually manufactured anew for each series of precast compound units. In the case of small series with different positions of the installation parts, it is cost-effective to use the shuttering metal sheet a number of times. This takes place in that the shuttering metal sheet is provided, before it is installed into the shuttering, with bores for a plurality of precast-compound-unit types, the bores are provisionally closed by suitable means, and the bore combination acquired for manufacturing a specific precast-compound-unit type is found by a specific locating process and freed from its provisional closure. By arranging the bores in the shuttering metal sheet in a fixed grid - expediently on the longitudinal axis and/or axes parallel thereto - or by using through-slots, the capacity for repeated usage of the metal sheet is further increased and the precondition for automatic occupation of the shuttering by various precast-compound-unit types is provided. <IMAGE>

Title: Method for producing connector sockets for optical waveguides
Inventor: ROSSBERG ROLF DIPL PHYS
IPC: G02B6/32
Filed: 1988-09-20
Abstract: In a method for producing connector sockets (1) for connector couplings, consisting of two halves, with ball lenses (3), in addition to the associated fibre sleeves (4), in each case containing one optical waveguide (8), also a flange part (9) is manufactured for each fibre sleeve. At first, the flange part (9) is pushed over the fibre sleeve (4), and the fibre core of the optical waveguide (8) is subsequently adjusted, by means of inserting the fibre sleeve (4) in a holder, of larger diameter, of the connector socket (1), in the focal point of the ball lens (3) arranged on the end face side (5) in the holder. The flange part (9) is then pushed to the rear side (10) of the connector socket (1) and subsequently fusion-spliced to the fibre sleeve (4). In this way, the optical waveguide (8) is fixed in the direction of the Z axis. The lateral maladjustment (misalignment) of the fibre core is now corrected by displacing the arrangement consisting of fibre sleeve (4) and flange part (9) in the XY direction and the flange part (9) is fusion-spliced to the rear side (10) of the connector socket (1). <IMAGE>

Title: Machine for assembling prismatic and rotational bodies and subassemblies
Inventor: FISCHER WILLI
IPC: B23P19/04
Filed: 1988-11-26
Abstract: The invention relates to an assembly machine as a three-dimensional production system, with a horizontally pivotable implement carrier traversable in two to three axes and also a work carrier which is vertically pivotable and horizontally displaceable towards the implement carrier such that the arrangement of the axes guarantees spatial accessibility at high rigidity and the axes are driven in an adjustable manner free of play and are numerically controlled. The implement carrier has two implement mountings for tools and grippers, which have quick-change systems, and assembly parts can also be fed through their axis. The work carrier has a favourable position for automatic pallet feeding, and the machines can be interlinked. The machine is especially suitable for the joining of mating parts due to a rigidity which lies between that of robots and that of machine tools as well as for the processing of corrections to the actual position value in order to dispense with expensive aids for compensating for alignment errors. <IMAGE>

Title: Device for the temporary reduction of the heeling (listing) force in sailing vessels
Inventor: LIESE FRIEDRICH
IPC: B63B15/00
Filed: 1988-12-20
Abstract: When the force of wind pressure is too great, the only possibility with sailing vessels is to take the sail out of the wind, or else to reduce the effective sail area by means of a reefing device. In order to provide a possibility which is relatively simple by contrast therewith for reducing the heeling force in sailing vessels given excessive wind pressure, provision is made of a disturbing device by means of which, particularly on the lee side, the air flowing longitudinally along the sail there is disturbed in such a way that the suction effect produced there is reduced and the heeling force is thereby diminished. The device is particularly suited for all sailing vessels, in particular sailing boats, ice yachts and land yachts, and also for rigs in windsurfing. <IMAGE>

Title: Bottle closure with separate pouring and aeration opening
Inventor: NEUMANN ERNST-HANS
IPC: B65D47/08
Filed: 1989-03-09
Abstract: The commercially available plastic and glass bottles, referred to here, for liquids of all types are containers whose bottle mouth is at least 1/3 of the internal diameter of the bottle, such as is primarily the case in bottles for juice, motor oil and antifreeze. It is known that the customary mineral water and wine bottles have a smaller clear bottle neck diameter than 33% of the clear bottle diameter. The bottles used specifically in the case of contents (oils and antifreeze agents) which are hazardous to the environment and have oversized pouring openings do not guarantee emptying without spillage. The problems are generally known as to how difficult it is in the case of full bottles with an opening directed towards the top to have to turn the bottle through virtually 90@ and, while doing so, to be able to bring about targeted emptying without spillage. Furthermore, in order to be able to use the existing bottle body, attempts are made to change only the pouring surface which is then subdivided into a larger (6) pouring opening and a small (7) air hole. The remaining partial surfaces of the actual bottle opening remain closed. A circumferential, internal lip seal (10) replaces the metal foil which is usually bonded on. The cap itself can be designed as a screw cap (4) with a push-bar closure or as a bonded cap (12) with a hinged bar closure with elevations. <IMAGE>
