Title: Process and device for the correctly positioned arrangement of a prefabricated reinforcement in a precast reinforced-concrete floor slab or the like
Inventor: BITTLMAYER HUGO
IPC: B28B23/02
Filed: 1987-04-30
Abstract: A process and a device for the correctly positioned arrangement of a prefabricated reinforcement (4) in a precast reinforced-concrete floor slab or the like, is specified, in which a liquid concrete (1) is first filled into an appropriate formwork or mould (2, 3), the prefabricated reinforcement (4) is subsequently placed on and brought into the required position by vibration. Spacers are no longer necessary; complete automation is possible; in particular the reinforcement (4) can be pressed somewhat into the liquid concrete (1) even before or during vibrating in. The required concrete covering (10) can be maintained extremely accurately. Errors caused by inserting the reinforcement by hand are avoided reliably. <IMAGE>

Title: Clamping Device
Inventor: GUTSCHE MARTIN
IPC: A63B29/02
Filed: 1987-05-21
Abstract: Clamping devices for mountain climbers are, ideally, to have bearing points for the clamping jaws in a rock crack, not to shift in the rock crack during use, not to shake lose, to be simple to handle and to combine light weight with maximum possible stability. Four clamping jaws (1), (2), grouped in two pairs of clamping jaws, are connected by a total of three spindles (3), (4), (5). The topmost spindle (3) determines the pivot axis of the pairs of clamping jaws relative to a support bar (6); the central one (4) determines the pivot axis of the clamping jaws of each pair relative to each other; and the bottom one (5) determines the access of connection for an actuating bar (7). Two springs (8) are arranged around the central spindle (4) and secured by their legs, as a leg connection, to the other spindles. The rope fixing eye (9) is formed by a flexible loop which is fixed to the bottom of the spindle and is looped over the topmost spindle. <IMAGE>

IPC: B23K26/00
Filed: 1987-07-17
Abstract: The invention relates to an apparatus for the continuous butt welding of strips and sheets by laser beams. The sheets or strips 1,2 are moved together in abutment and retained in the same level by tension rollers 3,4 on both sides and right and left of the welding gap.

Title: Device for compensating for switching delays
Inventor: ZIMMERMAN DAVID E
IPC: H03K17/28
Filed: 1987-12-11
Abstract: The present invention describes a switching delay compensation circuit for components which exhibit unequal turn-on and turn-off delays. A switching delay of the component is eliminated by introducing a fixed delay at the reference edge of a driver signal. Two out-of-phase signals are applied to transistors of the opposite type of conduction, which have an RC time constant. The output signals of the transistors of the opposite type of conduction are supplied to the driver transistors of the component. The time constants are selected in such a manner that each respective pulse edge of the out-of-phase input signal is delayed by the fall times and rise times of the component. An unbalanced embodiment is also described. <IMAGE>

Title: Method of controlling a graphic output device
Inventor: WALTER ROLF PROF DR
IPC: G06T15/20
Filed: 1988-06-24
Abstract: Method of controlling a graphic output device (PL, VS), in which surface data of at least one multiply curved surface is entered parametrically via an input device (E) into a control device (ST), and the surface data is prepared by differential geometry in such a way that output data for outstanding curves, i.e. contours, intersection lines and edges of the surface, is continuously generated, following their course, and stored in the curve file memory (DM), and continuously output, in relation to their visibility, as co-ordinate control signals (Ax, Ay; Su1, Sv1) and visibility control signals (DS, SZ). The requirement for memory and computer time is several times less, whereas the accuracy of the curves is high. The method is shown for different projection methods, for families of curves on the surface, and for several intersecting surfaces. <IMAGE>

Title: Method for laying a thread on a cross-wound bobbin
Inventor: KAMP HEINZ
IPC: B65H54/38
Filed: 1988-07-27
Abstract: The construction of a cross-wound bobbin depends essentially on how the individual layers in which the thread is deposited on the yarn cop are built up. When a cross-wound bobbin is being produced, the polar speed of the bobbin and the crossing angle must be monitored constantly in order to avoid patterning and too hard and curved an edge structure. In order to achieve an optimum bobbin build-up, it is proposed to change the rotational speed of the drive of a thread guide constantly during the entire winding run, so that the crossing angle is constantly increased and reduced at the bobbin ends. <IMAGE>

Title: Process for producing a compressible layer for offset printing blankets
Inventor: MUELLER WALTER RUDI DIPL ING
IPC: C12S99/00
Filed: 1988-07-27
Abstract: A description is given of a process for producing a planar-compressible elastomer layer of a printing blanket for the location-independently uniform transfer of printing ink from a printing forme onto a material to be printed, with gas-filled voids in a distributed arrangement in the elastomer layer. A layer consisting of an elastomeric material is produced with foreign bodies incorporated locally into the layer, which by a suitable conversion create the gas-filled voids incorporated into the layer. The said process is characterised in that helix polymers are incorporated into the layer as foreign bodies, which are enzymatically broken down and create the voids.

Title: Device for tensioning fret-saw frames
Inventor: WESTENHOEFER HEIKO
IPC: B23D51/12
Filed: 1989-03-23
Abstract: In the case of the known fret-saw frames, the fret-saw blade has to be screwed tight in the tensioned state of the fret-saw frame. With the new device, the saw blade can first be fitted and then the frame is tensioned by shifting the tensioning lever. By shifting the tensioning lever, the retaining bolt for the fret-saw blade is withdrawn in the housing and the fret-saw frame tensioned. This is achieved in that the guide pin in the retaining bolt is moved through an elongated hole in the tensioning lever until arrested. The device for tensioning fret-saw frames makes it possible to firmly tension the fret-saw blade and tension the frame separately, which is necessary especially for children.
