Title: Device for the coreless winding of web-shaped material
Inventor: MEEDE PETER
IPC: B65H18/22
Filed: 1987-05-02
Abstract: Device for the coreless winding of web-shaped material. The device consists of a belt conveyor device with deflector rolls for guiding belts running in each case adjacent to one another, of which some deflector rolls are arranged so as to be variable in their relative position with respect to one another, corresponding to the size of the reel. A first belt conveyor (8, 9, 10, D) is formed with a first, virtually horizontally running strand region (D1) to receive the reel (W) and a second upwardly directed strand region (D2). A second belt conveyor (B) is designed with a first, virtually vertically downwardly extending strand region (B1) for rotating the reel (W). A third belt conveyor (6, 7, E) is designed with a first obliquely upwardly extending strand region (E1). The first strand regions (D1, B1, E1) form a space, essentially triangular in cross-section, for the reel (W) (Fig. 1). <IMAGE>

Filed: 1987-05-25
Abstract: The knife, having a blade (2) that can be folded into the space between two side plates (1) has a lever (3) for locking the blade (2) in the open position, and by means of a turning moment applied about the lever pivot by a spring (4), the end section of the lever is pressed against the base (5) of the knife blade (2) to secure the blade. The lever is pivotally mounted by a shaft (8) supported in bearing recesses (9) formed in the inner surfaces of the side plates (1) and which do not penetrate to the outer surface of the side plates (1). A guide channel (10) communicating with each bearing recess, extends radially therefrom to the peripheral edge (15) of the side plate (1) so facilitating assembly of the pocket knife. Accordingly, the pivot shaft (8) is not exposed at the outer surface of the side plates with the result that the surface of the pocket knife can be easily finished. <IMAGE>
Patent DE-3720168-A1 (DE)
Title: Power transmission unit
Inventor: TERAOKA MASAO
IPC: F16D25/08
Filed: 1987-06-16
Abstract: Power transmission units comprise input-side and output-side rotary parts which are mounted coaxially to one another in a housing and can be turned relative to one another. Arranged between the input-side rotary parts and the output-side rotary parts is a clutch (13) which can be moved in the axial direction in order to bring about torque transmission between the input-side rotary parts and the output-side rotary parts. A movable pressure piston is provided for the engagement of the clutch. In known power transmission units, the pressure line for the pressure-actuation of the piston is passed through the rotatable parts and through parts fixed relative to them. This requires the use of dynamic seals, which are subject to wear and therefore have a tendency to leak. The power transmission unit has a pressure chamber (35) which is bounded by the piston (39) and the housing (33) and is used for the pressure-actuation of the piston (39). The pressure chamber is connected to a pressure source (44) and is subjected to pressure by the latter. The pressure source (44) is also used to control the pressure of the pressurised fluid in the pressure chamber (39). The power transmission unit is used in four-wheel drive motor vehicles. <IMAGE>

Title: Method of dental and oral hygiene and device for performing it
Inventor: RIESS ORTRUN DR
IPC: A61C17/08
Filed: 1987-08-07
Abstract: It is commonly believed that susceptibility to periodontosis is increasing continuously, and the damage produced by it on the periodontium leads to loss of teeth. It has been found that the pressurised water jet of conventional mouth douches either does not reach the subgingival zones or else causes detachment of the gingival margin. Moreover, the jet frequently tends to force food remnants and secretions even deeper into the gingival pockets rather than to remove them. The invention provides a method which is easy to implement and handle by everybody and with which the user can effect, in general additionally to the tooth brush, optimum dental hygiene and cleaning even in the subgingival zones at home and on journeys. This method comprises cleaning of the interperiodontal region and the gingival pockets by aspiration via a fine nozzle, expediently at a reduced pressure of 0.1 to 0.25 bar.

Title: Process for the protection and presentation of holograms
Inventor: RUECK ANDREAS B
IPC: G03H1/02
Filed: 1987-08-28
Abstract: By means of this process, holograms of all types can be embedded and polymerised in an optical plastic having a refractive index close to that of the holographic recording layer. Interfering air surfaces, which would otherwise impair ray transmission, are thereby eliminated. When polymerisation has taken place, a one-part, frameless presentation medium which is fracture-resistant and shatterproof is formed; the hologram is integrated in this medium and is protected against moisture, dust, UV radiation and other harmful environmental effects. It can be processed further in a variety of ways and is preferably employed in architecture and advertising.

Patent DE-3822191-A1 (DE)
Title: Method and device for the pyrolysis-free combustion of liquid fuels under low air pressure
Inventor: BLASCHKE HUBERT DIPL ING
IPC: F23R3/02
Filed: 1988-07-01
Abstract: The subject-matter of the invention is a carburetting method for liquid fuels based on a film evaporation "swirl (turbulence) chamber". Here, however, the eddying (vortex) flow drives a bladed (vaned) rotor "mechanically". In this case, flame gases recirculating from the combustion chamber are driven through an annular chamber together with the liquid fuel as a spiral flow. An electric heating conductor (resistor, element) on a part of the evaporating surface serves as starting aid. The mixture emerging from the rotor behaves like gas, ignites just downstream of the rotor and burns as a blue vortex flame without yellow flares. The method is independent of any atomisation, offers the possibility of continuous control, manages with a low flow energy, and is therefore also conceivable as the basis for a gas turbine combustion chamber concept.
