Title: Magnetic field therapy device with matrix coils
Inventor: SCHAUF GERHARD PROF
IPC: A61N2/02
Filed: 1984-02-03
Abstract: The magnetic field therapy devices that have been available hitherto are used for large-volume treatment. The invention permits the selective, preferential treatment of upper layers of the treated body, e.g. the skin, the skin plus fatty tissue or muscle parts, avoiding a considerable depth effect. In this case, the magnetic fields are generated by several small coils arranged next to one another in one plane. The plane may be flat or curved, rigid or deformable so as to be able, for example, to adapt to the body surface. In each case, two or more part-coils which can be controlled separately or in groups are used. Superposition of their part-fields leads to fields of predeterminable depth effect provided the parameters of coil diameter and coil spacing have been taken into account in the corresponding control program for the coil currents. By appropriate control it is possible to generate field rotations resembling the rotary fields of electrical machines, for example when coils or groups of coils are cyclically driven in the sequence 1-2-3-1-2-3, etc. The part-coils may be fixed with a larger or smaller spacing. <IMAGE>

Patent DE-3416094-A1 (DE)
Inventor: LANG GUSZTAV DIPL ING DR
IPC: E21D20/02
Filed: 1984-04-30
Abstract: A destructible container is arranged to maintain the components of a multi-component settable mass in separate regions until they are ready to be mixed for anchoring a fastener member in a borehole. The container is made up of an elongated outer cartridge and an inner cartridge positioned within the outer cartridge so that a space for one of the components is formed between the inner cartridge and the outer cartridge. The multi-component mass includes a resin component filled into the outer cartridge and a hardenable component filled into the inner cartridge. The space within the outer cartridge is divided into two separate regions, preferably one following the other in the elongated direction of the outer cartridge. The resin component is present in each region, however, a thixotropic agent is included in one region but not the other so that the viscosity of the resin component is greatly increased within the one region. Preferably, the increased viscosity is present in the region of the outer cartridge forming the trailing end of the container when it is inserted into a borehole so that flow out of the borehole is, for practical purposes, prevented. Accordingly, a resin component which is highly fluid prior to the mixing operation, such as methylmethacrylate (MMA) can be used.

Title: Ventilated or sound-engineered wall element and process for the production thereof
Inventor: POMPE GUENTER ING GRAD
IPC: E04C2/292
Filed: 1984-05-10
Abstract: A description is given of a ventilated or sound-engineered wall element (28) having two sheet-metal coverings (4, 6), connected to each other at opposite edges, and filling material (8) enclosed between said sheet-metal coverings. In the case of this wall element, the sheet-metal coverings are profiled, so as to engage in each other at the edges in question, in order to be connected to each other solely by being pushed into each other from the end of the profiling or by catching in each other. A clamping strip (26), subsequently inserted from the side when the coverings have been pushed into one another, can effect a mutual fixing of the two sheet-metal coverings (4, 6) and a continuous connection of successive wall elements (28) of this type. The wall elements can be connected flush against one another in order thus to form a virtually continuous, smooth surface without inserting cover mouldings or the like. <IMAGE>

Title: Drilling device for rock boreholes
Inventor: ROSENKRANZ PETER
IPC: E21B10/40
Filed: 1984-06-28
Abstract: For making boreholes, in particular with the rotary percussion drilling method, a drill bit is used whose radius can be changed by extendable auxiliary cutting edges. When the auxiliary cutting edges are accordingly retracted, the drill bit can thereby be retracted into the outer tube and lifted to the surface in order to exchange, for example, a drill bit which is no longer sharp. To this end, the drill bit has an axially displaceable plunger which through appropriate design of its thread can be displaced axially in the drill bit and which acts via end bevels on the respectively corresponding bevels of the auxiliary cutting edges. <IMAGE>

Title: Suspended bracket for the newspaper shelf
Inventor: JOOS GOTTFRIED
IPC: A47B63/02
Filed: 1984-10-06
Abstract: Previously, there have been no brackets available on the market which can be suspended in almost any size of slot of a shelf unit and serve specifically for supporting a newspaper shelf. The suspension hook on the bracket, the dimensions of which hook are 25 mm high, 10 mm deep and 3 mm thick, makes suspension in various ways possible. Only wooden shelves can be attached to this bracket. This has the advantage that the shelves ordered, because they are made of wood, can easily be supplied in any length. The height of the suspension bracket is always determined by the newspaper shelf which is inclined 15 DEG  downwards and the slot for the steel angle rail. Both parts, the shelf and the angle rail, must always be supported by the bracket.

Patent DE-3504399-A1 (DE)
Title: Shut-off device with lifting rotary pivoted flap
Inventor: SVOZIL PETER ING GRAD
IPC: F24F13/14
Filed: 1985-02-08
Abstract: A shut-off device with a lifting rotary pivoted flap for ventilation systems with air guide ducts of rectangular cross-section is proposed, in which the lifting rotary pivoted flap is, in the closed position, pressed in a known manner on the front side against a sealing seat surrounding the duct cross-section, from which seat, on opening, it is first raised a little parallel to itself before it is rotated into the open position. The invention consists in that, in such a shut-off device, the duct cross-section surrounded by the sealing seat and the lifting rotary pivoted flap 3 are essentially rectangular and in that the axis of rotation 8 extends parallel to a diagonal of the lifting rotary pivoted flap 3. The shut-off device according to the invention is, in relation to the generic known shut-off devices, characterised in that, for the rotary pivoted flap, it makes do with a greatly smaller travel between the closed position and the position, in which the rotary pivoted flap can be rotated about the axis of rotation, without colliding with its edge against the sealing seat extending along the duct wall. <IMAGE>

Title: Expansion compensation for lines which are laid in the earth
IPC: F16L51/00
Filed: 1985-03-22
Abstract: The invention relates to expansion compensation for lines which are laid in the earth, in the case of which compensation said lines are embedded or become embedded in expansion or shrinkage compensation zones. The invention is based on the object of preventing cavities originating in the earth/expansion zone/line system. This is achieved in that the compensating bodies (B, K, S) are formed from or consist of a container or composite system which is filled with a gaseous, fluid, gel-like, pasty and/or powdery displacement medium, is composed of two or more communicating containers and into which the line is embedded or becomes embedded such that the container or composite system is or becomes split into two spatial regions which are located opposite one another on both sides of the line longitudinal centre plane in such a manner that the force which occurs in the event of displacement of the line jacket in the expansion or shrinkage direction forces displacement medium out of the spatial region which is adjacent to the line jacket (L) in the movement direction into the other spatial region. Figures 1a and 1b show cross-sections through an expansion compensation device having containers in the form of bellows, one being in the installed state (Figure 1a) and the other in the operating state (Figure 1b). <IMAGE>

Title: Device for interchanging fluorescent tubes
Inventor: PFEIFFER GUENTHER
IPC: H01J9/00
Filed: 1985-03-05
Abstract: Device for interchanging fluorescent tubes, by means of which it is possible, in conjunction with telescopic lengthening and the elimination of previously required ladders, stepstools or other climbable equipment, to reach and interchange fluorescent tubes in lamp bodies having different mounts. By pulling on a cord, two gripping jaws configured in the form of pincers are opened and the mouth is brought to the width required for accommodating the fluorescent tube. A conveying cloth, which is connected at one end to the device in a resiliently yielding fashion and is guided on the outside around the sliding rollers which are provided on the head side of the two gripping jaws, encloses the fluorescent tubes on the inside of the mouth at right angles to their longitudinal axis. By pulling on a further draw cord, the conveying cloth is moved in the direction of the operator and causes the fluorescent tubes to execute an oppositely directed axial rotation which can be repeated or continued at will, until it is possible to remove the fluorescent tubes from their mount. This holds analogously also for the initial fitting of lamp bodies with fluorescent tubes.

Title: Roller container as a self-drivable closure container for collecting and transporting loads, as a mobile workshop or functional room for development aid uses
Inventor: SCHELOWSKY MICHAEL
IPC: E04H1/12
Filed: 1985-05-25
Abstract: Containers of all types are standing containers according to the prior art which require special lifting and transporting vehicles and are not themselves drivable. In contrast, in order to equip containers in industrial countries for aid actions and to transport them into emergency or development areas where they can be moved on in a self-driving manner independently of a special truck service and can be used flexibly matched to requirements, a universally usable roller container is required such as is proposed with the present invention. Its rolling characteristic is achieved by the cylindrical shape of the container shell, its reinforcement by circular container sides in skeleton construction with doors for access to and loading of the interior. For transporting loads, the roller container comprises an axle-mounted suspension construction which keeps the load in a stable position in terms of the centre of gravity below the axle pivot. The roller container can be moved by human strength and is therefore suitable for promoting the small business/free commercial economy. Standing and roof bars which allow various roof constructions with anterooms made of local material serve for the standing safety at the site of use. The roller container is thus suitable inter alia for supplying material in emergency areas, for the return export of small-scale commercial products, as a unit for works seminars, an energy cell or sanitary station, a laboratory or as an agricultural housing for production, ...
