Title: Optical device
Inventor: BRAEUNING GERHARD
IPC: G09B9/02
Filed: 1988-12-02
Abstract: The invention is about an optical device for learning purposes, in that it simulates specific situations, for example traffic situations, and the learner has the possibility of showing a specific behaviour in these situations, for example when driving a vehicle. For this purpose, the device is suitable for reproducing images (pictures) by means of a screen which has a liquid crystal display panel, and an interface for connecting up a computer. Under the liquid crystal display panel (14) a picture original (17), provided with a data strip (19) which can be scanned, is arranged in a replaceable manner to be viewed jointly with a liquid crystal display. The data strip (19) of the picture original (17) put underneath projects into the area of a data scanning device (20) and the data which are stored on the data strip (19) are fed as control signals via a computer to the liquid crystal display panel (14). The data strip (19) contains a program which is assigned to the picture original (17) and can be reproduced on the liquid crystal display panel (14) by means of a keyboard (15) as changing information. <IMAGE>

Title: Method and device for the folded presentation of a web of material
Inventor: ANKERSSON BILL
IPC: D04H1/74
Filed: 1989-03-18
Abstract: A primary mineral wool web (1) is deposited by a delivery conveyor (2', 3') essentially horizontally onto a receiver conveyor (11) which runs at a significantly lower speed than that of the mineral wool web (1), as a result of which a secondary mineral wool web with a multiple of the surface weight of the primary web (1) is formed. In order to carry out the folding, air from a blow-off box (33, 34) in the area between the delivery conveyor (2', 3') and the receiver conveyor (11) is blown alternately against the two sides of a freely hanging part of the mineral wool web (1). The mineral wool web is in each case guided sideways so that loops form, the extent of these loops being delimited at the top by delimiting members (the lower ends of 2', 3') parallel to the presented layers of the mineral wool web. The secondary mineral wool web is pressed against the receiver conveyor (11) by means of air currents from blow-off boxes (37, 38). <IMAGE>

Title: Rapid-action coupling with coupling elements capable of being interconnected in an axially fixed but releasable manner
Inventor: STAUDACHER WALTER
IPC: F16D1/116
Filed: 1989-03-25
Abstract: Into a bush part with a housing having a frontal coupling recess there can be coupled a coupling pin with a catching contour. Received in cutouts in the housing wall are locking elements which are radially movable between a locking position projecting radially into the coupling recess and an unlocking position forced out of the latter, which positively engage in the catching contour of the coupling pin in the coupling position and are retained in their engagement position by means of a locking sleeve movable relative to the housing. The locking sleeve is movable counter to the action of the retaining spring into an unlocking position in which the locking elements are able to yield radially outwards freeing the coupling pin. The coupling bush is fitted with a safeguard which permits actuation of the locking sleeve into a position urging the locking elements into their locking position only when the coupling pin has been coupled into the coupling recess.

IPC: B65G57/03
Filed: 1990-09-29
Abstract: A device stacks and also separates flat sheets of e.g. wood, chipboard, foamed polystyrene, plastics, cardboard, etc., as single sheets or sets. In the stacking operation the materials are conveyed steadily or intermittently to rollers arranged at the top of the device so as to rest against a stop; from here they are moved by the bar of a lateral transporting system above the rollers on to a platform at the side which drops beforehand through the height of one set of material and into the stacking position; when the stack has been completed the reverse movements take place to take away the layers from the stack. The roller conveyor (11) is hinged about an axis (12). Sheets (17 or 18) are carried on a tilted conveyor (11) up to the stop (25), whereupon the material is moved transversely by the transporter (29) and a bar (27) over to a stacking space by means of a belt (28) with four toothed belts (21). The roller conveyor (11) is adjustable for different thicknesses of material. The stacking space contains a platform with adjustable height which is set at a height to take only a few layers (16) of the material. To separate material from a stack the platform, is lowered to the level of a conveyor (36) and materials are moved off. At the same time the machine is operated again in the feed mode so that the fresh material are formed into a new stack. ADVANTAGE - The device operates automatically. It has a simple design requiring little maintenance, no pit for its accommodation, and little shop space. It operates at high speed around 50 m/min. It makes little noise. It is reliable. Its function is not significantly influenced by the surface properties of the material. (16pp Dwg.No.1/16)
