Abstract: A densitometer apparatus (410) is disclosed and is adapted to provide color density measurements of object samples. The densitometer apparatus (410) comprises a source light (580) for projecting light toward an object sample comprising a control strip (588, 620). A reflection optics assembly (576) is adapted to measure light density reflected from the object sample when the object sample is in the form of a paper control strip. A transmission optics assembly (618) is adapted to measure transmission density of light rays projected through the object sample when the object sample is in the form of a film control strip. A motor assembly (426) operating with a drive wheel assembly (434) and idler wheel assembly (440) automatically moves the object sample (588, 620) through the apparatus (410) adjacent the source light (580). A pair of guides (468, 470) are selectively adjustable by the operator to control movement of the object sample (588, 620) through the apparatus (410). In response to input from a key switch assembly (492) activatable by the operator, the apparatus (410) is adapted to perform various color density measurement and calibration functions, and display appropriate information to the operator through the use of a visual display (490).

Abstract: Device for the vertical and automatic stacking of sheets, and for feeding cover plates onto the stacks consisting of sheets, using a single device for feeding the cover plates, it being possible to move the device for feeding the plates in an interference displacement located in the prestacking displacement so as to move up and down in a vertical plane, which interference displacement is determined by a lower insertion position on the fork of the lower cover plate and an insertion position of the upper cover plate on the finished stack. The stop for the cover plates and the upper end of the side parts of the displaceable carriage for the sheet stack are also arranged so as to be capable of moving backwards and forwards in a vertically arranged plane. Stacks are produced which have a relatively large stacking height with the same prestacking displacements. In addition, the efficiency of the stacking device is increased.

Abstract: To protect the data in memory units in which the individual memory entries consist of a data section (DAT) subdivided into several sections (DAO...DAn) and a test section (PA) protecting the data section, and in which optionally selectable sections of the memory entries can be changed by write operations, the memory entry in each case affected by a write operation is read, in parallel in time, for deriving the new test section (for example CBD) with the aid of the old test section and the changes in the data section resulting from the write operation, and checked for the presence of errors. When a correctable error (CS1) is present, an error correction is performed on the memory entry read which only results in a new derivation of the new test section if the sections of the memory entry to be changed by the write operation are affected by the error (CS1) found.   <IMAGE>

Abstract: Laser-warning method and a laser-warning arrangement, which laser-warning arrangement is intended to warn of laser light from a laser beam source which is used for guiding projectiles, missiles and the like, for example laser light from a pulsed laser beam which is directed towards a target area. The time for the laser beam to reach the laser-warning arrangement, the so-called impact time, is calculated from a first amplitude value, measur­ed at a first point in time, of the scattered light from the laser beam and a second amplitude value, measured at a second point in time, of the scattered light from the laser beam, and the measured time difference between the said first and second points in time on the basis that the amplitude raised to a constant is proportional to the distance to the laser beam according to the equation D = K · A n , where K and n are constants, D is the perpen­dicular distance to the laser beam and A is a measured amplitude value. The laser-warning arrangement comprises a rotatable optics system with two light inputs, a fixed detector system which detects the magnitude of the light coming in via the light inputs of the rotatable optics system and transmitted through the optics system to the fixed detector system, and an evaluation unit which determines the impact time in accordance with the above equation. The optics system comprises, counting from each light input, a first cylindrical lens, prism, reflector, filter, second cylindrical lens, diaphragm and glass block.

On place un filtre (22) de vapeur d'huile en amont dudit filtre (28) d'adsorption d'humidité, afin de maintenir une efficacité d'adsorption élevée. La purification du réfrigérant dans sa phase gazeuse peut alors être considérablement améliorée.

Title: Heat-expandable plastic laminate, process for making it and use thereof.
Inventor: GSELLMANN HELMUT
IPC: C08J5/04
Filed: 1990-09-27
Abstract: A heat-expandable laminate contains highly elastic reinforcing fibres like glass fibres in the elastically compressed state and a thermoplastic duromer synthetic material as the binder. To manufacture this laminate, glass fibre mats are first impregnated with a duromer synthetic material (a ''plastic''), one or more of such mats are superimposed and compressed in a press and taken to temperatures at which the plastic softens and the assembly is then cooled in the compressed state so that the plastic re-hardens and forms the finished laminate. The expandable laminate is preferably used for electrically insulating spacers. To this end, for example, a section of laminate (7) is fitted between neighbouring coil parts (5) of a stator of a high-voltage machine. During the subsequent ordinary vacuum-pressure impregnation of the stator to complete the coil insulation, the laminate sections (7) are heated by the hot impregnating agent, whereupon the plastic of the laminate sections softens and expands as the stress on its elastically compressed fibres is relieved, thus completely filling the interstices between the coil parts (5). The impregnating agent filling the pores of the laminate is then cured together with the plastic of the laminate and the stator insulation.
