Title: Device for punching and, if desired, embossing flat materials
Inventor: LOECHT HEINRICH VAN DE DR ING
IPC: B31F1/07
Filed: 1988-05-13
Abstract: A device for punching and, if desired, embossing flat materials, such as corrugated cardboard, especially in the form of sheets, has a punching and embossing device (14, 14'') which has a base frame (15, 15') with a die plate (22, 22') and a chase (23, 23') which is arranged above the die plate (22, 22') and has a punching mould (28, 28') with at least one punching tool. Furthermore, a drive unit (4) is provided for driving the base frame (15, 15') and the chase (23, 23') with respect to one another. In order to achieve a good punching output while leaving the structure very simple, the base frame (15, 15') is arranged so as to be stationary and the chase (23, 23') is designed to be capable of being driven so as to be pivoted in such a way as to perform a scissor-like movement with respect to the base frame (15, 15'). The device can be designed as a tandem model. <IMAGE>
Patent DE-3819733-A1 (DE)
Title: Impact packing
Inventor: BERGER WOLFGANG DR ING
IPC: E21B33/12
Filed: 1988-06-10
Abstract: For injecting liquid grouting materials into concrete, rock or other structural parts, the structural parts to be grouted must be bored and the boreholes must be filled with packing. Plastic packing of conical shape is known. This packing is knocked into the borehole and due to its conicity is mostly secured only to the outer borehole margin. The subject matter of the application avoids the connection of only small area between the conical impact packing and the borehole wall and thus the associated risk of inadequate tightness at higher grouting pressures and the risk of the external concrete cover breaking out. The subject matter of the application consists of the frustoconical packing and an anchoring sleeve which is shaped in the same way on the inside, presses the packing against the borehole wall over its entire flank length by expanding forces when it is being knocked in and therefore reliably anchors it in the structure and forms a seal to prevent grouting material from flowing around it.

Patent DE-3827312-A1 (DE)
Inventor: KASDAN HARVEY LEE VAN
IPC: G06T7/00
Filed: 1988-08-11
Abstract: An electrical image of the field of view is formed by a camera (12). The electrical image is digitised and processed in a processor (10) to form a plurality of different representations of the electrical image where each different representation is a representation of a different parameter of the field of view. These representations comprise numbering pixels consecutively in the x direction and continuing on successive lines to define a Green's function for use in area calculation, and assigning each pixel location a value equal to the sum of all the pixels having the same y value but lower x value of pixel location P(x,y) for use in calculation of integrated optical density. The positional information, which represents the boundary of the object, is also generated. In response to the positional information that represents the boundary of the object being generated, corresponding boundary locations in each of the different representations are traced. The different parameters for the object from each of the different representations are calculated as the boundary locations are traced in each of the different representations. <IMAGE>

Filed: 1989-01-19
Abstract: The device for forming a weir over the width of a building opening (1) comprises a threshold (2) which can extend vertically out of a housing (3) which is to be arranged such that it is sunk in the ground. In the extended weir position, longitudinal border strips (8) of the threshold (2) press, with longitudinal border strips (9) of the housing (3), a strip of a sealing means (10), with the result that a water-tight weir projects over the width of the building opening (1).

Title: Optical disc playback system - has screening plate with needle aperture to control input to detector element
Inventor: CHIKUMA KIYOFUMI
IPC: G11B7/1381
Filed: 1989-04-21
Abstract: An optical player for use with either video discs or digital audio discs has a light sourcea (1), beam splitter (2), disc (4), photo detector (5) and lens mounted in an actuator (6). Located between the splitter and the detector is a screening plate (9) with a small aperture (8).

Title: Bale breaker for extracting fibre from compressed bales - comprising pressure rollers having sensors which generate upwards signal for extn. unit
Inventor: PINTO AKIVA DIPL ING
IPC: D01G7/10
Filed: 1989-09-27
Abstract: The bale breaker, to extract fibre flocking from compressed bales, has pressure rollers which act as monitors (1,2) which move vertically by a given amount, with sensors (14) which generate an upwards signal for the extn. unit (5) when the rollers are displaced by a given amount and, at the same time, an advance redn. signal. The height adjustment for the extraction unit ends as soon as the leading roller (1) in the advance direction is moved from a signal generating position. A second sensor system (16) monitors the rotation of the rollers (1,2) and, when both rollers (1,2) are still, generates a downwards signal for the extn. unit (5). The sensor (14) has a switch for the uppermost lifting position to trigger an upwards signal for accelerated upwards movement, and a second switch which, after a given lifting movement triggers a signal for a creeping upwards movement up to the top position. ADVANTAGE - The mechanism compensates for different bale heights, with immediate reaction to a different material level, without requiring a computer program for control.

Title: Short-circuit protection of GTO thyristor pulse inverter - allows conduction through intermediate circuit fuse during first half-cycle only before blocking at zero current
Inventor: EGGERT BERNHARD DR ING
IPC: H02H7/122
Filed: 1989-10-28
Abstract: The three gate conditions of a gate turn-off thyristor (GTO) are realisable by a control circuit with a control input (ST) to a three -position switch (S). In position (1) a DC source (U1) delivers a postive firing current to the gate (G), causing conduction from cathode (K) to anode (A). In position (2) the thyristor is biased off by an inverse DC voltage (U2). In position (3) a low resistance (R) extinguishes the anode current automatically at a zero-crossing. ADVANTAGE - Thyristor is not damaged either by internal or external short-circuits, and only intermediate circuit fuse is blown.

Patent DE-3939161-A1 (DE)
Inventor: RITTER WOLFGANG DR
IPC: A61K6/884
Filed: 1989-11-27
Abstract: Described is the use of physiologically compatible tocopherols, in particular vitamin E, as inhibitors against premature initiation of polymerization in reaction systems, capable of radical-initiated polymerization, which are brought, before and/or after polymerization, in contact with, and in particular implanted in, living human or animal body tissue. The reaction systems, or the polymers formed by them, can be degradation-resistant. In a particularly important embodiment, however, appropriate compositions or moulded products are used which are broken down, in particular absorbed over a controlled period, by the living body. The invention also concerns surgical bonding agents suitable for bonding body tissue, these agents being based on a radical-activated adhesive component which is used mixed with a radical inhibitor. The bonding agents are characterized by the fact that the inhibitor, or the greater part of it, is vitamin E. The preferred compositions are those described, free of physiologically undesirable solvents and production-related solvent residues.
