Title: Method and apparatus for blowing pneumatic conveying lines empty
Inventor: SCHMIETA HEINRICH
IPC: B65G53/52
Filed: 1988-06-18
Abstract: In multi-line pneumatic slow-conveying installations, the relatively large quantity of air which is required in each case for the occasional blowing-empty of individual conveying lines, which is performed at a comparatively high speed, is not suddenly removed from the usual pressure container but continuously diverted from the compressor air flow and fed into a separate pressure container from which it can then be discharged in a short time and at a correspondingly high speed, when required. By this means, it is possible at the same time to maintain the uninterrupted slow conveying in the remaining conveying lines without having to raise the compressor power or dimension the usual pressure container of the installation for the relatively large quantities of conveying air required for blowing empty.
Patent DE-3822361-A1 (DE)
Title: Trough-shaped transporting container
Inventor: JOCHAM HANS
IPC: B65D88/12
Filed: 1988-07-01
Abstract: A trough-shaped transporting container comprises two mutually opposite side walls (1) and two end walls (2 and 3) running obliquely to its standing surface. Formed in one (2) of the two end walls (2 and 3) is an opening (5) which can be closed by a movable wall part (8). In order to be able to pivot this pivotably mounted wall part (8) out of the end wall and use it as a ramp to the interior of the container, the opening (5) of the end wall (2) is designed to taper towards its lower edge, and the wall part (8) closing said opening (5) can be raised from its closed position, in which it rests with lateral edge regions against the insides of the lateral opening edges, into a higher position in which it can be pivoted outwards through the opening (5). <IMAGE>

Patent DE-3830167-A1 (DE)
Title: Key-ring
Inventor: HEIDEN ALBRECHT THEODOR
IPC: A44B15/00
Filed: 1988-09-05
Abstract: The key-ring has an essentially U-shaped basic part (1) which exhibits a hook (5), open to the outer side of the ring, at the end of a first (3) of its two legs (3, 7) and consists of a material which is resilient at least to a limited extent. At the end of the second leg (7) of the basic part (1), a lever (11) is mounted such that it can pivot about a pivot pin (9) running essentially perpendicularly with respect to the plane of the ring. Connected to the lever (11), at a spacing from the pivot pin (9), via an articulation (13) is a clip (15) whose end remote from the articulation (13) forms a web (19) which, when the lever (11) is pivoted away from the second leg (7) for opening the key-ring, can move beyond the hook (5) of the first leg (3). When the key-ring is in the closed state, the hook (5) engages behind the web (19), and the clip (15) keeps the lever (11) pivoted, in an over-dead-centre position, against the ring outer side of the second leg (7). The spacing of the web (19) from the articulation (13) of the clip (15) is dimensioned such that, when the key-ring is in the closed state, the hook (5) engages behind the web (19) of the clip (15) in every position of the lever (11), and the web (19) can move beyond the hook (5) only with resilient deformation of the basic part (1). Expediently, the clip (15) has a stop (25) which limits the pivot movement of the lever (11). The stop may also be formed by an extension of the lever (11), said extension ... on that side of the pivot pin (9) which is directed away from the articulation (13) ...

Title: Screen comprising wire cables
Inventor: EBELING ROLF
IPC: E02B8/02
Filed: 1988-09-13
Abstract: Fine screens of the construction known from the prior art are difficult to free of residues, have a relatively large hydraulic resistance due to the small throughflow cross-section, and have a relatively high-outlay production. The screen comprising wire cables can be produced with a relatively small gap width and a large free cross-section. The cable comprises a single, endless wire cable which is guided in a number of loops around two rolls (2 and 3). Consequently, there is only one cable connection and all the loops have the same degree of stressing, which can be changed as required. At the discharge point, the cables run through a stripper (5) which cleans them totally of screenings. The screen can be pivoted out of the channel. Said screen is conceived particularly for use in municipal and industrial clarification plants. <IMAGE>

Title: Method for reducing the dimensions of a reflector of an antenna
Inventor: ANTONY HORST
IPC: H01Q15/16
Filed: 1988-09-23
Abstract: A method is specified for reducing the dimensions of a parabolic, circular reflector (1) of an antenna for transportation purposes. To this end, the installation position of a holder (4) (which belongs to a supporting body and is in the form of an annular disc) on the rear side of the reflector (1) is initially marked. After this, the reflector (1) is cut through, with the holder (4) removed, at at least one separation point (7) (which is covered by the holder in the installed position) along a circular line over a length which corresponds to a centre angle of a maximum of 140@. The cut is made at both ends of the separation point (7), in the direction of the edge of the reflector (1), until it projects out of the region covered by the holder (4) in the installed position. The holder (4) is subsequently permanently connected to the reflector (1), leaving free that region (10) which is located on the side of the separation point (7) facing the edge of the reflector (1) and is to be cut off from the reflector (1). At this point, holes for accommodating mounting elements are introduced on the region (10) of the reflector (1) to be cut off, under the holder (4) and on both sides of the cuts (8, 9) which are to be continued to the edge of the reflector. Finally, the cuts (8, 9) located at the ends of the separation point (7) are continued to the edge of the reflector (1), so that the cut-off region (10) can be removed. <IMAGE>

Title: Cylinder or roller having a cylinder or roller body which can be adjusted in the transverse direction to be in-register
Inventor: SCHOEPP HELMUT
IPC: B41F13/58
Filed: 1989-04-26
Abstract: The invention relates to a cylinder or a roller having a cylinder or roller body which can be adjusted in the transverse direction to be in-register. The invention is based on the object of providing a cylinder or a roller, in particular for guiding webs through web-fed printing machines, whose cylinder or roller body can be detached from the shaft with few manipulations, allows smooth displacement and positioning on the shaft and can be fixed reliably on the shaft with few manipulations. According to the invention, the object is achieved in a cylinder or roller body, in which the end disc is mounted on both sides in each case with a centrally arranged bore on the respective shoulder of the shaft, essentially due to the fact that the bore in the end discs consists of a first - outer - part of greater diameter and a second - inner - part of smaller diameter, that a bearing bush, arranged in the inner part of the bore, together with the assigned shaft shoulder, forms an axial plane bearing in each case, and that a friction coating is embedded in each case in the outer part of the bore and is expandable in the radial direction under the influence of a compression force acting axially - which can be applied to the friction coating by a clamping ring and clamping screws. <IMAGE>
