Title: Scaffolding for mounting on sloping roof - is supported on pairs of beams which are pivoted together at upper ends
Inventor: LANGER GEB LAYHER
IPC: E04G3/26
Filed: 1990-10-27
Abstract: Scaffolding for carrying out work in the region of a roof ridge is supported at each end by a pair of beams (29.1,29.2) with the members of each pair being pivoted together at their upper ends and with each beam lying on one side of the sloping roof. Each beam has a number of cross-members which serve as footholds and also as anchor points for triangular frames (54). These frames can be adjusted so that the upper member (50) is horizontal irrespective of the slope of the roof. The platform (52) which rests on the upper member (50) is thus held level. USE/ADVANTAGE - Scaffold for working on a roof, has level platform irrespective of slope of the roof.

Title: Multi-socket bicycle-drive mechanism - incorporates toothed rings sliding axially and individually on hub
Inventor: BERGLES EDUARD ING
IPC: B62M9/14
Filed: 1990-11-29
Abstract: The multi-sprocket drive mechanism couples the chain from a bicycle pedal sprocket to the rear wheel. It has a series of coaxial toothed rings of different dia. and between which the chain is transferred, to give the desired ratio. A freewheel is provided between the series of rings and the hub. The rings (A -B) slide axially on the hub. Those not in use can be moved so as to leave distances between them less than those (a) at the left and right between the ring in use and between it and adjacent ones.  These distances can be reduced to nil. USE/ADVANTAGE - Derailleur-type bicycle gearchange accommodates a larger number of toothed rings.

Title: Colour matching desk for visual and measuring quality control of printed sheets - has X=Y control deflecting projector so that light beam covers while sheet area rapidly and photoelectric scanner supplying evaluating unit
Inventor: WENIGER RUDI
IPC: G01B11/00
Filed: 1991-01-05
Abstract: The position of the scanner (5) is automatically detected. An overhead projector (7) directs a light beam (8) onto any selected position of the printed sheet (2) placed on the test desk (1).

The scanner, in the form of a hand-held densitometer, colour analyser or video measuring head, includes a photosensor (10) which immediately delivers a signal when the light beam impinges on it. The evaluating unit (11) assigned to the photosensor cooperates with the deflection stage and registers the position of the measuring spot from the deflection of the light beam at the time a signal is delivered from the photosensor. ADVANTAGE - Measuring at any point manually selected. This position is registered without hinderance of visual evaluation.

Title: Timing method for hump shunting operation - uses speeds of different length rakes of trucks to determine delivery times into sidings
Inventor: SOREMBA VOLKER DIPL ING
IPC: B61J3/02
Filed: 1991-11-29
Abstract: In a preceding dummy run, each rake is considered both as a well- and as a badly-running unit. The pushing speed is determined from the difference between the times required for release and delivery into particular sidings. A speed pattern is established for the actual times required from passing a datum point at or near the crest of the hump to reaching all the sidings, for different lengths of rakes. From this the maximum travel speed for delivery to the sidings and the corresponding minimum speed for release are calculated, and used to control handling of subsequent rakes of different types. USE/ADVANTAGE - Control of hump shunting operation. Easy determination of times in off-line dummy run beforehand.

Patent DE-4142631-A1 (DE)
Inventor: LASCH MANFRED
IPC: A24B1/04
Filed: 1991-12-21
Abstract: The invention relates to a method for the separation of tobacco parts consisting of tobacco rib pieces (rib pieces) from tobacco parts which consist of tobacco fibres that are stuck, agglomerated or folded together. 
<??>The invention resides in warming the tobacco fibres by passing in steam, as a result of which the tobacco fibres which are stuck, agglomerated or folded together are substantially detached from each other and opened. The tobacco parts thus steamed, warmed and possibly moistened are then subjected to a screen operation, in which the rib pieces are separated from the detached and opened tobacco fibres. 
<??>The advantage of the method according to the invention resides in the fact that the tobacco fibres, after they have been detached from each other and opened and separated from the rib pieces, are reused, so that the losses of expensive tobacco can be reduced.

Filed: 1992-04-16
Abstract: A device for the uniform distribution of a two-phase stream consisting of gaseous and solid components comprises a filter housing which is divided by a rigid plate into a raw and a pure gas chamber. Filter elements are secured at apertures in the plate and the raw gas chamber has an inlet for the two-phase stream and the pure gas chamber has an outlet for the gaseous components of the stream freed from the solid components by the filter elements. To the inlet of the two-phase stream is connected a pipe system running inside the raw gas chamber and branching between thefilter elements which divides the two-phase stream into at least two partial streams and takes them upwards past the filter elements to the rigid plate where the partial streams leave the pipe system. Near the exits of the partial streams there are deflecting devices which deflect the partial streams in the raw gas chamber freely downwards.
