Patent DE-3243311-A1 (DE)
Title: Imaging system
Inventor: GUSTAFSSON OLLE
IPC: G09F19/12
Filed: 1982-11-23
Abstract: Imaging system consisting of a compound image and a filter through which the image can produce different visual impressions. The nature of the imaging system, which is chiefly intended for the purposes of instruction or advertising, requires a certain activity on the part of the viewer and enables mass production at low cost, as well as distribution and application without advanced technical aids. According to the invention, the imaging system has at least two different, jointly mounted image samples of which the first has a colour and a relative brightness with a weak contrast relative to the environment. The second image sample dominates over the first and principally has a complementary colour relative to the principal colour of the first image sample. Furthermore, the imaging system has a filter with a colour which represents a complementary colour relative to the principal colour of the first image sample. The filter is suitable for changing the visual impression of the compound image from dominance of the second image sample to dominance of the first image sample, specifically by tinging the light impinging on or reflected from the compound image.

Title: Elastic shaped body for relaxation of various body parts
Inventor: DEUSCHER BRUNO
IPC: A47C20/00
Filed: 1983-02-11
Abstract: The shaped body is formed by an ellipse subdivided by a longitudinal axis and a transverse axis. The individual parts or segments can be used, individually or several together, to support the body as and when required. The division of the elliptical shaped body results in four ellipse segments of the same shape which meet all requirements of body support with their possible combinations. Reduction of the elliptical shaped body to a basic principle with round forms and division into segments thereof in the manner shown permits great variability during application. The individual segment bodies of the ellipse are connected to one another by hook and loop materials and can be separated from one another or variably joined as and when required.

Title: Drive for a heating tool of a packaging machine
Inventor: WICHERT NILS VON DIPL ING
IPC: B65B51/10
Filed: 1983-09-27
Abstract: The invention relates to a drive for a heating tool of a packaging machine for sealing thermoplastic wrapping materials. In order to keep the time for which the heating tool 7 is in contact with the wrapping material 6 independent of the prevailing machine speed, a lever 9 which supports the heating tool 7 is actuated via two radial cams 16, 17, which act on a common or a double control rail 12, 13. When the packaging machine changes speed, the basic settings of the radial cams 16, 17 are twisted in relation to one another in such a way that the effective total length of the cam sections of both radial cams 16, 17 responsible for holding the heating tool 7 in the working position is shortened when the speed of the machine increases and respectively extended when the speed of the machine decreases. <IMAGE>
Patent DE-3345561-A1 (DE)
IPC: G05D16/20
Filed: 1983-12-16
Abstract: Combination of a gas pressure regulator and a magnetic safety valve provided with a common closure valve body used at the same time as a regulation member, which is within the gas flow in the closure direction and is loaded by the closure spring during a disconnection of the magnet. The influence holes and channels are arranged so that the chamber on the inlet side, the working pressure chamber and the working membrane are pneumatically connected only when the magnet is set on and so that, when the magnet is set off, the chambers and the influence holes are separated so that only the forces in the closing direction may be exerted, that the compensation of the forces acting in the direction opposite to the closure direction is superfluous, the closed conditions remaining complete even in the case of defective membranes and that, in case of rupture of the working membrane, the valve closure body takes the closing position, respectively remains in the closed position. The set value for the gas pressure regulation part is mechanically achieved or electromagnetically influenced for example by a servo-regulator measurement device.

When a cable core assembly in which such cores (10) are twisted is filled with a hot wax-like substance, the hollow bodies (20) foam up and thus enlarge the proportion of the filling compound containing encapsulated gas, which is associated with a considerable reduction in the dielectric constant. <IMAGE>
Patent DE-3410241-A1 (DE)
Inventor: MUELLER ALBRECHT DIPL CHEM DR
IPC: C08L29/04
Filed: 1984-03-21
Abstract: In order to preserve the solubility of films and moldings of polyvinyl alcohol in cold water even under the action of an aggressive atmosphere, in particular a strongly acidic atmosphere, the thermoplastically processable polyvinyl alcohol composition used for the preparation of the films and moldings is stabilized by the addition of a water-soluble polymer or copolymer which is composed to the extent of at least 70% by weight of monomer units which are carboxylic acid amides at least monosubstituted on the amido nitrogen. N-vinylpyrrolidine, N-vinyl-N-methylacetamide and the alkali metal salts or the ammonium salts of 2-acrylamido-2-methylpropanesulfonic acid have proved to be particularly suitable representatives of this group of compounds.

Title: Method and device for recording address conversion pairs in an address conversion buffer memory
Inventor: KUBO KANJI
IPC: G06F12/10
Filed: 1984-05-03
Abstract: A data processing system for handling a virtual address space exhibits a dynamic address converter for converting logic addresses into real addresses. The dynamic address converter exhibits an address conversion buffer memory (14) for temporarily storing several address conversion pairs with in each case one logic address and a corresponding real address. When the address conversion pairs have to be recorded in the address conversion buffer memory (14), an addressing control is carried out in order to check whether each of the converted real addresses is a valid memory address or not and recording of conversion pairs for which addressing errors have been found is suppressed. Correspondingly, only address conversion pairs free of addressing errors are recorded in the address conversion buffer memory (14). <IMAGE>

Title: Arrangement for controlling die cushions
Inventor: RUCHSER ERICH
IPC: B21D24/08
Filed: 1984-05-07
Abstract: The invention relates to an arrangement for controlling the die cushion of a die-cushion press. Connected to the pneumatic cylinder of the die cushion on the output side is a hydraulic cylinder, the piston of which is rigidly coupled to the die-cushion piston. During the working stroke of the press, the compressed air is forced out of the pneumatic cylinder without air loss into an air receiver while, during the return stroke, the compressed air is fed in to the pneumatic cylinder in a throttled manner and the hydraulic fluid is withdrawn from the hydraulic cylinder in a throttled manner. The energy conversion is thereby distributed between two throttle valves, excessive heating of the oil thereby being avoided. The two throttle valves can be controlled by a common set point generator and the return speed of the die-cushion piston can thus be varied and, in particular, adapted to different strokes of the press.
