Patent DE-3634920-A1 (DE)
Title: Clean air cabinet for sterile articles for storage and as a sluice
Inventor: HOELTER HEINZ DIPL ING
IPC: A61L9/16
Filed: 1986-10-14
Abstract: It is known that the treatment and nursing areas of hospitals have cabinets in which medicaments, infusions, instruments and thermolabile goods having to meet high requirements on hygiene are stored. However, when the cabinet doors are opened the articles kept in the cabinets are necessarily contaminated by organisms contained in the ambient air. In order to prevent this the invention proposes to build into such a cabinet a forced ventilation which is provided with a germ-proof, preferably bactericidal and fungicidal, filter. The filter may be a chemisorption filter whose clean air keeps the cabinet under superatmospheric pressure via a fan. The individual compartments of the cabinet are comparatively small and are supplied with air by individual tubes or channels that can be removed for disinfection, so that on opening of the cabinet it is only the air in the particular open compartment that escapes, while all other cabinet compartments are still kept under superatmospheric pressure. In accordance with its leakage sites the cabinet is always charged with clean air from the chemisorption filter at the minimum setting of the fan, and the full fan power is effective only during opening; e.g. via a pressure contact on the door rebate. <IMAGE>

Patent DE-3719006-A1 (DE)
Title: Lightweight transmission with a large reduction
Inventor: BURKHARDT GERT DIPL ING
IPC: F16H7/02
Filed: 1987-06-06
Abstract: The large reduction of the transmission is achieved by constructing it as a differential with sun gears and revolving planet gears, the transmission of power from the sun gears to the planet gears being effected by means of double-sided toothed belts, roller chains or similar tension-transmitting means in such a way that a large number of teeth are in engagement while, at the same time, the free belt or chain length is very small. The belts or chains which revolve with the planet gears simultaneously serve to hold the planet gears on the circumference of the sun gears without the use of a planet carrier. As a result, it is possible, using toothed belts for example, to achieve high torques and a high torsional rigidity with low tooth loading and it is thus possible to produce the gears from lightweight materials instead of steel.

Title: Interior travelling apparatus for combustion chambers or large vessels
Inventor: DYMARCZYK GUENTER
IPC: E04G3/30
Filed: 1988-05-03
Abstract: Interior travelling apparatuses for large chambers, e.g. for the combustion chamber of a thermal electric station, comprise a working platform which can be suspended on load-bearing cables and is to be introduced into the chamber through an access hatch. In order to increase the degree of safety against accidents, an interior travelling apparatus which can be mounted entirely from outside the chamber is to be provided. According to the invention, the working platform (1) is composed of a flat walkway (5) and of railings (16, 17) and of superstructures (A) which comprise a protective roof (22, 23). The load-bearing cables (2, 3) are guided about the folding joints (32, 33) of the superstructures (A) such that, when tension is exerted on the load-bearing cables (2, 3), the superstructures are automatically erected. The working platform can thus be mounted entirely outside the chamber, pushed into the chamber in the collapsed state, and erected automatically in the chamber by exerting tension on the load-bearing cables, after which said working platform can be walked upon for the first time by the fitter. <IMAGE>
Patent DE-3814966-A1 (DE)
Inventor: BALL ANTHONY
IPC: D01H4/48
Filed: 1988-05-03
Abstract: In order to start spinning in an open-end spinning device, the fibre feed which is interrupted during standstill is restarted on a fibre-collecting surface and brought immediately to full production speed. For this purpose, the combed condition of the fibre tuft at the time of starting (tL) is determined. The time of starting and the doffing speed of the fibers are adapted to the time at which the fibre feed to the fibre-collecting surface becomes effective. The yarn is subjected to a multiple-phase doffing acceleration. The first phase (GA3) of the doffing acceleration is synchronized with the joining of the fibres at the return end of the yarn. At least one additional phase (GAc', GA'') of the doffing acceleration serves to attain and/or maintain the desired mass of fibres. The control device for implementing the starting process is connected to a device for determining the combed condition of the fibre tuft at the time of starting and controls the doffing of the fibres in function of said condition. At least two fibre-accelerating devices can be selected by the control device.

By virtue of a special coupling system, it is possible to be able to fit any number of balconies one above the other. The anchorage elements are designed such that the formation of condensation in the room interior is avoided and cold bridges do not occur. For rapid and simple mounting, the individual parts can be plugged together and screw-connected to one another, with the result that welding and caulking work can be dispensed with. The anchorage of the load-bearing structure is possible not only on buildings with reinforced-concrete floors, but also on buildings with wooden-joist floors.
Patent DE-3817307-A1 (DE)
Title: Separation sheet
Inventor: BERGER RUDOLF DIPL ING
IPC: B42F21/00
Filed: 1988-05-20
Abstract: The separation sheet (16) designed in strip form, has parallel perforations (18, 20) and (32, 34) at one end region, whose distance apart corresponds to the distance between the perforation and the arrangement of the alignment needles (24, 26) of a stitching strip (22). Consequently, the separation sheet (16) can be used both to separate documents (10) arranged directly on alignment needles (12, 14) of a file and to separate documents (30) which are arranged on a stitching strip (22) without the region of the separation sheet (16) lying opposite the perforation projecting from the file. Moreover, perforations (40, 42; 44, 46) are formed at the longitudinal edges (36, 38) so that the separation sheet can also be used in a perpendicular position, in which case the region lying opposite the perforations (18, 20; 32, 34) projects above the upper edge of the documents. <IMAGE>

Patent DE-3826245-A1 (DE)
Inventor: BRUECKNER RAIMUND
IPC: B22D41/14
Filed: 1988-08-02
Abstract: The present invention is drawn to a regulating device of a metallurgical vessel for regulating the flow of molten metal from the vessel. The device includes a fixed refractory part defining a first cylindrical peripheral surface of the device and a movable refractory part that is rotatable and/or slidable relative to the fixed refractory part and defines a second cylindrical peripheral surface sealingly engaged with the first cylindrical peripheral surface. An actuating device is connected to the movable refractory part for rotating and/or sliding the movable refractory part relative to the fixed refractory part. The cylindrical peripheral surfaces of the refractory parts are spaced apart from one another so as to define an annular gap therebetween. In order to ensure that during operation the refractory parts can be moved relative to one another by the actuating device while preventing the penetration of molten metal into the annular gap, each of the refractory parts has a coefficient of thermal expansion which, when the device is subjected to a high temperature corresponding to the melting temperature of a molten metal, causes a clearance fit to be established between the peripheral surfaces that is effective to prevent molten metal having a melting point at the same predetermined high temperature from penetrating between the peripheral sealing surfaces while allowing the movable refractory part to be moved relative to the fixed refractory part.

Inventor: BORMET GEB KUHN
IPC: B62B15/00
Filed: 1988-11-28
Abstract: A device for sliding on snow consists of a moulded body provided on its lower side with a base sliding surface (2), two control runners (3), two lateral braking profiles (4) and a possibly two-part stopping brake profile (8), and on its upper side with profiled tread surfaces with a shoe-binding device (21). A brake claw (6) which passes through the device from the lower side to the upper side constitutes a braking element (6) in the form of a round or profiled steel spring comprising an M region and an N region. The M region controls the tension of the brake claw by moving from the vertical, disengaged position through 90 DEG  in the direction of the tread surface to a horizontal, rest position of the brake, and re-tensions the brake claw by moving in the opposite direction as far as a profiled stop (38), i.e. by moving from the horizontal position to the vertical, functional position of the brake. The N region ensures the braking function for the device when the braking element is in its vertical, functional position or allows the device to slide freely on the snow when the brake is in its horizontal, rest position.
