Title: Depth vibrator for soil compaction with reversible vibration form and direction
Inventor: EGEY ZOLTAN THOMAS DIPL ING
IPC: E02D3/054
Filed: 1981-02-16
Abstract: Depth vibrator for the compaction of soils, with the possibility of reversing the direction and form of the vibrations by means of a change in the direction of rotation of the drive motor. The purpose of the reversal according to the invention is to reduce only the friction between vibrator and soil during the lowering operation by means of vertical longitudinal vibration but without achieving substantial compaction, which would impair the lowering operation. When the final depth is reached, the form and direction of the vibrations is changed by reversal of the direction of rotation of the drive motor into a horizontal rotary vibration (similar to the movement of a mechanical watch balance wheel), which on the one hand compacts the soil by means of blades (Figure, item 6) but on the other hand for the first time enables the drive to be placed above the soil. The position of the drive above the earth permits the use of drive motors of any size, unbalance masses and bearings whose size and capacity was greatly restricted in the previous depth-vibrator constructions by the restricted space ratios under the ground. <IMAGE>
Patent DE-3107004-A1 (DE)
Inventor: WOHLRAB WALTER
IPC: B29C45/82
Filed: 1981-02-25
Abstract: An apparatus for closing a mold in an injection-molding operation has a double-acting main piston that is connected to a mold-carrying plate and that move axially in a main cylinder. A rapid-action piston extends into a small-diameter bore in the main piston, and the rear cylinder wall is formed with a large-diameter fill passage connected directly to a sump. A positioning cylinder is fixed on the main cylinder and contains a positioning piston axially fixed on the rapid-action piston and having in the positioning cylinder a rearwardly directed face larger than the face of the rapid-action piston and forming with the positioning cylinder a pressurizable positioning chamber. A passage extends axially through the rapid-action piston from its cylinder to the positioning chamber. A valve element is fixed axially to the rapid-action and positioning pistons and is displaceable between a rear closed position engaged with and blocking off the fill passage and an open position forward therefrom and exposing the fill passage. Valves connected between the reservoir, pressure source, and chambers serves in a rapid-action closing position to supply fluid under pressure to the positioning chamber while venting the front chamber to the reservoir and thereby moving the positioning piston, rapid-action piston, and valve element forwardly with displacement of the latter into the open position. In a mold-closing position, the valves supply fluid under pressure to the rear chamber while venting the front and positioning chambers for moving the valve element back into the closed position.

Title: Hydraulic control valve with pneumatic actuator for web-guiding devices
Inventor: WULF JOHANNES
IPC: B65H23/032
Filed: 1981-06-13
Abstract: The hydraulic control valve (1) with pneumatic actuator (2) for web-guiding devices serves for the automatic correction of deviations of a travelling web from the desired position. An actuating diaphragm (5) subdivides the space between two chamber walls (6.1, 6.2) into two diaphragm chambers (7.1, 7.2). On the side, facing away from the actuating diaphragm (5), of one of the chamber walls (6.1) there is disposed a valve chamber (9) with a valve body (10) which is adjustable therein and is connected to the actuating diaphragm (5) via an actuating rod (16). Opposite the actuating rod (16), the actuating diaphragm (5) bears a pin (23) which is led through the diaphragm chamber (7.2) facing away from the control valve (1) and through an opening (24) in the chamber wall (6.2) of said diaphragm chamber and, outside the diaphragm chamber (7.2), bears a stop (25) between which and the chamber wall (6.2) a spring element (22) is arranged. In the diaphragm chamber (7.2) penetrated by the pin (23), there is located a spring element (21) which is supported on one side against the actuating diaphragm (5) and on the other side against the chamber wall (6.2) and is designed as a sleeve-shaped spring body made of an elastomeric plastic which surrounds the pin (23) with a clear spacing and, by sealing contact both with the chamber wall (6.2) and with the actuating diaphragm (5), seals the diaphragm chamber (7.2) with respect to the sleeve interior space and with respect to the opening (24) at the pin side. Both spring elements (21, 22) are pretensioned with respect to one another by means of the actuating diaphragm (5) and the pin (23). Transverse displacements of the web produce pressure changes which operate the actuating diaphragm (5). The control valve (1) controls a servomotor effecting the return of the web. <IMAGE>

Title: Device for controlling the even engagement of the printing unit cylinders
Inventor: JOHNE HANS
IPC: B41F13/28
Filed: 1981-06-22
Abstract: The invention relates to a device for controlling the even engagement of the printing unit cylinders on offset printing machines, in which the engagement is carried out by rotation of the eccentric bearing bushes separately on each side of the machine. The aim of the invention is to avoid reductions in the quality of the printed sheets and damage to the machinery by bearing journals being tilted due to unintentional misalignment of the printing unit cylinders during engagement. The object of the invention is to prevent the printing machine being started up in the case of uneven engagement by means of a control device which is coupled to the adjusting means for engaging the printing unit cylinders. According to the invention, this is achieved in that control devices are connected on each side of the machine to the adjusting means which cause the engagement of the plate cylinder (1) and the rubber-covered cylinder (2), which control devices interrupt the main current circuit in cases of uneven engagement. Field of application: offset printing machines. <IMAGE>

Title: Eccentric drive with stroke adjustment
Inventor: PFISTERER HORST ING GRAD
IPC: F16C3/28
Filed: 1981-09-30
Abstract: The invention relates to an eccentric drive with stroke adjustment, which has an eccentric (1) which can be driven in rotation, an eccentric bush (2) mounted on the latter so as to allow the bush to be twisted, and a connecting-rod bearing (3), rotatably mounted on the said bush, of a connecting rod (4), the eccentric bush (2) being lockable in discrete positions either to the eccentric (1) or to the connecting rod (4), and the actuation of the stroke adjustment facility when the eccentric bush (2) is locked to the connecting rod (4) and the operation of the eccentric drive when the eccentric bush (2) is locked to the eccentric (1) is effected by rotating the eccentric (1). The object is to specify a simple design for adjusting the stroke to just two different lengths. This object is achieved by the fact that the discrete positions are offset relative to one another by 180 DEG  of centre angle, that the locking of the eccentric bush (2) on the eccentric (1) can be brought about by outwardly displaceable sliding members (6) and the locking of the said bush in the connecting-rod bearing (3) can be brought about by inwardly displaceable sliding pins (13), and that the sliding pins (13) can be displaced as far as inner end positions in which their radially inner end faces lie in the bearing surface between the eccentric (1) and the eccentric bush (2). <IMAGE>

Title: Process and apparatus for removing impurities from textile material
Inventor: STEITZ WINFRIED
IPC: D06B23/26
Filed: 1981-10-10
Abstract: The invention relates to a process and apparatuses for removing water-soluble or water-decomposable impurities, such as, for example, size or suchlike substances, from textile material, in which the textile material is treated with water and subsequently brought into contact with an organic solvent, by means of which the water is displaced out of the textile material. In order to prevent some of the impurities or other substances present on the textile material from passing, during the water treatment, into water located in the treatment apparatuses, the invention provides for feeding the water to the textile material in such a way that it does not flow off again from the textile material, for example a textile fabric web. This can take place, for example, by means of paddles (2, 4, 16), spray devices, scrapers or the like, by means of which the water required is brought onto the fabric web. Subsequently, it is then removed in a known way from the textile material, together with the impurities, in a downstream solvent-treatment apparatus (5) by spraying with and/or dipping into solvent. <IMAGE>

Title: Device for locking a shutter blind carrier in an electronic camera shutter
Inventor: SUZUKI AKIRA
IPC: G03B9/08
Filed: 1981-11-16
Abstract: A shutter blade or a shutter blind can be actuated by means of a driving or carrier element (18) which can be locked in a shutter cocked position by a blocking lever arrangement (12, 16), which is provided with a first lever (12) having a curved end or nose (12a), which can be brought to engage with the carrier element (18), and a second lever (16) equipped with an iron piece (16c) which can be attracted by an electromagnet (22, 42), which in the energised state pivots the first and second levers (12, 16) together (via a bend) in a direction to release the carrier element (18) for activating the shutter blind. The second lever (16) can be locked against a movement, in order to actuate the carrier element (18) by a linearly movable tracker as a function of the actuation of a rapid return mirror mechanism. When a shutter release button is pressed to elevate the mirror (49) to initiate an exposure process, the second lever (16) is disengaged from the tracker and is attracted by the energised electromagnet (22, 42) to trigger or release the carrier element (18). After the exposure has been carried out, the mirror (49) swings back, so that the tracker can lock the second lever (16) against movement. The first lever (12) is then in a position in which it can lock the carrier element (18) in the shutter cocked position. <IMAGE>
