Patent DE-4035095-A1 (DE)
Title: Multi-ply form with attached
Inventor: JAMESON JOHN R
IPC: B42D5/02
Filed: 1990-11-05
Abstract: The multi-ply form with labels and multiple form parts includes first and second webs secured one to the other with repositionable adhesive. Different types of labels are permanently secured to the second web. At least one label of the second web registers with a die-cut portion in the second web and both the one label and die-cut portion register with a die-cut section of the first web.  When the webs are separated, the die-cut section is adhered to the second web, enabling removal of the one label therefrom in a manner to provide securement to a surface using either repositionable adhesive or permanent adhesive. Additional holding power may be provided when using the respositionable adhesive by providing a further die-cut segment.

Title: Printing equipment for pictorial sketching and wiping of printing plate - polarises or depolarises plate coated with ferroelectric material
Inventor: HIRT ALFRED DIPL PHYS DR RER N
IPC: B41C1/10
Filed: 1990-12-07
Abstract: The printing plate (2) is polarised by application of energy pointwise. For depolarisation or change of polarisation, an extinguishing appts. is applied. A strip of rod electrodes (1) is directly directed into the printing plate. Each electrode (4) can be controlled by an electron beam (5).

Patent DE-4112769-A1 (DE)
Inventor: BERGMEISTER JUN JOSEF
IPC: B66F9/065
Filed: 1991-04-19
Abstract: The vehicle has a carrying surface with a frame (2) to which two pivoting arms (3) are linked which are at a distance apart in the width direction of the vehicle and are in turn connected in an articulated manner at their free end to a fork lift (7). Sitting on the two pivots (4, 8) of each pivoting arm (3) are two guide rollers (12, 13) of the same diameter, over which a rope (14) runs which is fastened to the fork lift (7) and to the vehicle-side guide roller (12) or to a power lift of the vehicle. The pivoting arms (3) can preferably be pivoted by means of two piston/cylinder units (10, 11) so that the fork lift (7) can be transferred between a position on the carrying surface of the vehicle and a working position, on the ground, behind the loading surface. In the process, the fork lift (7) is held parallel by the rope (14). If the fork lift is to be tilted in an intermediate position of the pivoting action, the rope (14) fastened to the fork lift (7) is released, a drive device (43) restoring the original state after the tilting action. The hoisting and transfer device (1) has virtually no adverse effect on the roadworthiness of the vehicle. <IMAGE>

Filed: 1992-06-10
Abstract: In a window, door or the like with two wings installed directly next to one another, without a fixed mullion, in a fixed frame, each wing, at least on the rebate circumferential surface of the mutually adjacent spars, is equipped, in a stepped profile groove, with a fitting consisting of a cover rail and of an espagnolette guided longitudinally slidably under the latter. Locking studs or the like movable by the espagnolette of one fitting can be put into and out of locking engagement with locking plates 5 which are seated on the cover rail 12 of the other fitting 6. Provided in the cover rail 12 of the other fitting 6 are groups of recesses 13, 14 arranged distributed in a grid-like manner in the longitudinal direction thereof, and each recess group comprises, together with predetermined systematics, two different forms of recesses 13 and 14. One of these recess forms is designed as a long hole 14 which extends parallel to the longitudinal direction of the cover rail 12. The other recess form 13 is matched in its contour to the cross-section of material extensions or studs 15 on the rear side of the locking plates 5. The long-hole length of one recess form 14 is, in turn, coordinated with the centre distance 18 between two successive recesses 13 of the other recess form, and each long-hole recess 14 in the cover rail 12 is assigned, in the espagnolette located underneath it, a longitudinal slot, the length of which corresponds at least to the sliding travel of the espagnolette. Also, each locking plate 5 contains a longitudinal slot 17 which has substantially longer dimensions than the length of a long-hole recess 14 in the cover rail 12, there being used as a fastening means for the locking plate 5 a screw 16 which passes through the longitudinal slot 17 of the locking plate 5, any of the long-hole recesses 14 in the cover rail 12 and the respective longitudinal slot assigned to the latter and located in the espagnolette, towards the bottom of the stepped profile groove of the standing wing, whilst the material extensions 15 of the locking plate 5 can be engaged fixedly into the associated recesses 13 of the cover rail. <IMAGE>
