Title: Ground-working appliance
Inventor: SCHWARZ ULRICH DIPL ING
IPC: A01B73/04
Filed: 1985-11-21
Abstract: The ground-working appliance has a frame middle part (4) and frame side parts (6) which are pivotable relative to the frame middle part from a horizontal working position into a vertical transport position about a horizontal axis (8) extending in the direction of travel (F). After the upward pivoting, the frame middle part (4) can be lowered, during which lifting hydraulic cylinders (20) are relieved completely. Ground clearance (a) sufficient for transport still remains thereafter. 
<??>The advantage of the complete relief of the lifting hydraulic cylinders (20) is that the transport position is maintained permanently even when the appliance is uncoupled from the hydraulic system of a tractor.

Title: Process and apparatus for making openings in containers of thermoplastic materials
Inventor: THEWS HEINZ
IPC: B26D7/08
Filed: 1986-02-06
Abstract: Process for making openings in containers of thermoplastic materials, in particular in plastic fuel tanks for motor vehicles. A tool designed as a sonotrode, having a cutting edge shaped in a way corresponding to the shape of the opening to be made, is placed onto the location of the container to be provided with the opening, is excited by ultrasound of comparatively high amplitude and an advancing force directed into the interior of the container is exerted on the tool until the heat produced by the ultrasonic oscillations in the cutting edge region together with the cutting pressure of the cutting edge cause the section of the container wall surrounded by the cutting edge to be cut free without any shavings. The section of the container wall lying inside the tool cutting edge is at the same time held securely on the tool and, once cutting through of the container wall has been carried out, is lifted off the container together with the tool and is then detached from the tool.
Patent DE-3605617-A1 (DE)
Title: Set of points for model railways
Inventor: SCHMID EUGEN
IPC: A63H19/32
Filed: 1986-02-21
Abstract: A set of points for model railways has two displaceable tongues of track which are mounted on a displacement bar, a drive for the longitudinal movement of the displacement bar, and a spring element which permits a resilient deflection of the tongues of track out of each of the two end positions of the tongues of track. In such a set of points, in order to make a resilient design of the drive unnecessary, it is proposed that the bearings of the tongues of track be displaceable on the displacement bar parallel to the direction of displacement of the displacement bar, that the bearings be held in a central position by the spring element, from which central position they can be deflected to both sides against the force of the spring element, and that the drive displaces the displacement bar into its end position only to the extent that the bearings, when one tongue of track comes into contact with an outer rail, are displaced at most slightly from the central position.

Title: Optoelectronic systems for contactless measurement during travel of: cross-sectional contour of railway rails, cross-sectional contour and characteristics I, C, QR of railway wheels, cross-section of railway waggons, and lateral and height deviations of railway rails
Inventor: SCORTEANU ROMEL DIPL ING
IPC: G01B11/24
Filed: 1986-04-08
Abstract: The invention relates to optoelectronic systems for contactless measurement during travel of: cross-sectional contour of railway wheels, cross-sectional contour and characteristics I, C, QR (as these have been defined by the UIC) of the wheels of railway waggons or tractive (motive power) unit, diameter of railway wheels, cross-sectional profile of railway waggons, and lateral and height deviations of railway wheels. The determination of the cross-sectional contour of railway rails and wheels is performed by reading, with the aid of two optical systems arranged in different planes, of the positions of an illuminated point which scans/sweeps the rail or the wheel rim. The contour is recorded in a rectangular coordinate system. The electronic circuits are digitised and filter out the disturbing reflections and the noise due to lateral vibrations. The wheel diameter is measured in the running zone during travel and without contact. The determination of the height and lateral deviation is performed by measuring the distances between a rigid rod and the unused zone of the railway rail, in order to exclude the influence of the material rail wear from these measurements. <IMAGE>

Title: Device for manufacturing bag packagings
Inventor: ROOVERS GIJSBERTUS CORNELIUS F
IPC: B65B9/213
Filed: 1988-03-10
Abstract: A device for manufacturing tubular bag packagings (4) has a tube forming arrangement (10, 11), a longitudinal-seam sealing arrangement (12) and a transverse-seam sealing arrangement (15) which is moved up and down. In order to draw the tube (2) flat in the region of the transverse seams, the device has spreading fingers (23, 24) inside the tube and roll-up flexible delimiting walls (25, 26) outside the same. It also has to this end a stretching arrangement (30) with two interacting grippers (31, 32). One gripper (32) is designed as a clamping gripper and secures the tube (2) on its longitudinal seam (3) by clamping. The other, opposite gripper (31) is designed as a suction gripper with a suction arrangement (61, 62), which takes hold of the part of the tube lying opposite the gripped longitudinal seam by suction so that, when the two grippers are drawn apart, a slipping of the layers of the tube which have been taken hold of and thus a length compensation is possible so that the sealing jaws (15, 16) of the transverse-seam sealing arrangement (15) strike a region of the tube (3) which has been drawn completely smooth. To relieve the tube (2) of longitudinal stresses, a pivoting bottom (50) which can be pivoted away is also envisaged. <IMAGE>

Title: Pressure-medium cylinder for actuating ventilation and smoke-outlet louvres
Inventor: FREMZ KLAUS
IPC: F15B15/26
Filed: 1988-05-18
Abstract: A pressure-medium cylinder (1) for actuating ventilation and smoke-outlet louvres, the piston rod (2) of which is constantly loaded in operation in the direction of arrow (A) by an external spring (not shown), is provided with a locking device which can be actuated or unlocked solely as a function of pressure. To this end, a locking pin (13) can be axially displaced via a piston (12), specifically against the action of two springs (14, 15) of different strength. When a high pressure is applied, the locking pin (13) is moved into the area of catch balls (8) which as a result bear against corresponding annular surfaces (18) of a catch ring (5). If the pressure is lifted, the locking pin (13) first of all stays in its catch position, since it is clamped in place by the catch balls (8). If a lower compressed-air pressure is applied, the cylinder piston (3) is now relieved so that the catch balls (8) no longer apply any clamping forces to the locking pin (13) and the latter can be returned into its initial position, as a result of which the cylinder piston (3) together with piston rod (2) are freely movable again. <IMAGE>
