Patent DE-3137584-A1 (DE)
Title: Means for reinforcing profiles so that they do not buckle
Inventor: KNORRE WERNER
IPC: E04C3/10
Filed: 1981-09-22
Abstract: In order to prevent profiles from buckling in, said profiles are provided with a circular tube cross-section. The resulting tube, which is closed at both ends, is filled with highly compressed gas, the pressure of which counteracts a deformation, which is necessary for buckling to occur, of circular cross-section. Owing to the compressed gas, the load-bearing capacity of the profile is thus reinforced without increasing its weight.
Patent DE-3139459-A1 (DE)
Title: Method and device for testing the lubricity of lubricating greases and oils in the mixed friction range
Inventor: BRUGGER KURT
IPC: G01N33/30
Filed: 1981-10-03
Abstract: In mechanical engineering, in particular, lubrication has been found to be a very important problem in relation to fault-free running, for example, of the drive units. In gearboxes and in other rotating machine parts, a wide variety of loads occurs, requiring the use of a corresponding variety of greases and oils for their lubrication. A precise test method for the lubricants was hitherto unknown, at least as regards repeatability. According to the invention this is achieved in a device as shown in the patent drawing by applying a grease or oil film to the surface of a friction roller (1). A fixed test roller (2) which is offset with its axis at 90 DEG  to the friction roller (1) is then pressed with a defined force onto said friction roller (1). The friction roller (1) is then caused to rotate for a certain time and in this process an imprint is established on the surface of the test roller (2). The permissible loading of the lubricant when used in the mixed friction range can be deduced from this, in particular from the ratio of the contact force and the area of the imprint. <IMAGE>

Title: Method for correcting test, measurement or processing paths on pipe interior manipulators inside curved pipeline regions
Inventor: WEBER ROBERT
IPC: G21C17/017
Filed: 1981-10-06
Abstract: Method for correcting test, measurement or processing paths on pipe interior manipulators (M) inside pipeline regions (r1, r2) that are curved or have an irregular inner contour, in which method at least one displaceable member (m2) for a working head (K1) of the manipulator is clamped in place and centred on the inner circumference of the pipe with the aid of two supporting flanges (f3, f4) mutually spaced along the pipe axis, and for the purpose of assuming its working position or rest position the working head (K1) can, together with its working device (32) is adjusted towards or away from the pipe interior circumference in an adjusting plane normal to the pipe axis, and is subjected during the working operation to path control in at least two co-ordinate directions, the circumferential direction and the axial direction. Before the execution of the actual working operation, the pipe circumference in the region of the working path is traversed and continuously observed in preferably equal circumferential steps with the aid of a receiver probe (TV) of a remote observation device fastened to the working head (K1). If axial displacements of the probe (TV) from its working path desired position are observed, the probe is readjusted by means of an axial correction setting signal into the desired position of the relevant site on the circumference, and a sequence of these axial correction setting signals, respectively assigned to a circumferential position signal corresponding to the relevant position on the circumference, e.g. an incremental angular momentum generator, is stored in a path/co-ordinate memory. The recorded sequence of the axial correction setting signals is, finally, used to control the axial positioning motor of the working device as a function of circumferential angle during its working operation. <IMAGE>

Title: Waistbelt closure
Inventor: KRETZSCHMAR RUEDIGER
IPC: A41F9/00
Filed: 1982-02-15
Abstract: For easier handling, additional decorative designing and achievement of a psychological benefit for the users the waistbelt is provided with an infinitely adjustable burred closure. The beginning of the waistbelt is fixed to the inner side of the navel cover at the guide bracket located on the navel cover. The other end of the waistbelt is guided around the waist by the guide bracket (including any second guide bracket that may be present) and is firmly connected to the beginning of the waistbelt by means of the burred closure. In addition to guaranteeing a reliable function, this type of closure permits infinite adjustment and decorative use of the outer surface of the navel cover, maintained in its entirety, onto which any sign of the zodiac or the national colours of a state can be applied. With due consideration of the fact that all human beings were born attached to the cord by the navel under a particular sign of the zodiac, application of the signs of the zodiac on the navel cover of the waistbelt closures can be made with particular effect.

Title: Guide handle for a vacuum cleaner
Inventor: JACOB GERNOT
IPC: A47L9/32
Filed: 1982-02-27
Abstract: A guide handle for a vacuum cleaner consists of a guide tube in which a handle is removably attached. A hook for winding up a vacuum cleaner cable in the non-operational position of the vacuum cleaner is attached to the handle. In order to pivot the hook through 90 DEG or 180 DEG from its holding position, in which it points away from the guide tube and runs approximately parallel to the handle, into a release position, the hook is connected to a pin which is mounted by both ends so as to be rotatable in each case in an associated bearing opening in adjacent wall parts of a handle portion of tubular construction. In the holding and the release position or positions of the hook, the latter is held via a catch member between mutually parallel resilient tongues of the handle. The catch member is formed by a portion of the pin arranged between the pin ends, which portion has at least two mutually parallel side surfaces, but preferably a square or rectangular cross section. In each catch position, the spring tongues lie flatly against the mutually parallel outsides of the catch member and, when the hook is pivoted, are pressed resiliently apart until the hook has been pivoted into the holding or release position.

Title: Heat insulating web for heat insulation of a steep roof in the space between the rafters, and steep roof insulated therewith
Inventor: LOECHNER MANFRED DIPL ING
IPC: E04D13/16
Filed: 1982-09-23
Abstract: In order to obtain heat insulation at least over the entire rafter height in a steep roof, a lower heat insulating web (3) with a lamination web (5) acting as vapour barrier is countered by an upper heat insulating web (9), the lamination web (11) of which lies on the outside and is fastened to the outer end faces (8) of the rafters (1). Whereas the inner lamination web (5) has a diffusion-equivalent air-layer thickness of over 100 m, the outer lamination web (11) has a considerably lower diffusion-equivalent air-layer thickness of, for example, a few metres. The required ventilation of the upper heat insulating webs (9) is provided on the outside of the associated lamination webs (11) via a ventilation gap (15) which is guaranteed by counter-laths (13) secured, beyond the lamination web (11), against the outer end face (8) of the rafters (1). The upper heat insulating webs (9) are installed advantageously parallel to the eaves and ridge, it being possible to produce mutual overlapping by means of laterally projecting edge strips (12, 12a) of the lamination webs (11) and to prevent penetration of rainwater. At the same time, the lamination webs (11) take on the function of conventional trussing webs and can form an emergency roofing extending up to the ridge. <IMAGE>

Patent DE-3302318-A1 (DE)
Title: Gas turbine
Inventor: WEBER FRANZ-JOSEF
IPC: F02C3/05
Filed: 1983-01-25
Abstract: Gas turbines are also manufactured with radial blades as heat engines. They also require an air compressor with a long shaft. Their component cost is still too high and thereby prevents reduction of the production costs. Their metal turbine wheel blades can only be exposed to temperatures of up to 1050 DEG C and those of ceramic up to 1350 DEG C, at which their power limit is reached. The present gas turbine has only one wheel disc as common carrier of the air compressor and turbine wheel blades. Cooling air annular nozzles are directed at the turbine wheel blades, which nozzles are connected to the air compressor. In a post-connected turbine wheel heat exchanger the exhaust gases, due to the air circulation on the aircraft hollow-profile blades, transmit intense heat to the fresh air for the combustion chamber. It is intended for use as a single engine in light aircraft, motor boats, units and car wash systems, as a compound engine in passenger aircraft, buses, trucks, motor yachts and large machine units.
