Title: Process and apparatus for producing a composite web
Inventor: SCHOLLKOPF ERNST
IPC: B05C1/08
Filed: 1983-08-04
Granted: 1988-12-08
Abstract: An apparatus for manufacturing a sandwich web comprises first and second rotatable applicator rollers which are mounted so as to form an adjustable first roller nip therebetween adjacent adhesive applicator means which applies a film of adhesive to each of the applicator rollers for coating on respective sides of a substrate web. The apparatus includes a pivotal arm which contains a first laminating roller which forms a nip with the first applicator roller so that a laminating web may be fed thereover to engage the adhesive on one side of the substrate. In addition, a second laminating roller is contained by the pivotal arm and it may be brought into association with the first laminating roller to form a third roller nip so that a second liner may be laminated to the adhesive on the opposite face of the substrate. In accordance with the method of the invention the substrate is fed between the first roller nip and is coated on each side with an adhesive to a predetermined level which is regulated by the rotational speeds of the applicator rollers and it is thereafter directed over a portion of the surface of the first laminating roller so that the laminating web which is fed thereon is bonded to the adhesive on the one side of the substrate. The second liner is then fed on the opposite face with a second laminating roller which is arranged in association with the first laminating roller to define a third nip therewith. The rotational speeds of the laminating rollers in their adjustable positions relative to each other and to the applicator rollers permit selection of the film amount of adhesive and the bonding which is effected between the liners and the substrate.

Abstract: In a helical scan video recorder in which the magnetic heads are arranged on bimorph piezoelectric actuators it may be desirable, in order to counteract depolarization of the piezo-electric elements, to bias these elements. This is possible without the use of additional slip rings if the electrode to which the drive voltage is applied is connected, via a diode, to the electrode to which the bias is applied and the bias is applied, alternately with the drive voltage, at instants at which the associated magnetic head is not used. If the (lower) drive voltage is applied the diode is cut off and the bias is isolated from the drive.

Title: Mounting device for spectacles
Inventor: WIEDMANN HELMUT
IPC: G02C5/00
Filed: 1984-10-30
Granted: 1989-07-13
Abstract: This invention relates to spectacles in which are spectacle lens is connected to an individual component, for example a flange, by means of a fatening device. In the spectacle lens the two ends of a borehole are expanded into two borehole widenings which are engaged with a first protrusion on the flange and with a connecting element that is connected to a pin leading to the first protrusion. In addition, the flange has two further protrusions supporting themselves on the border of the spectacle lens, so that a four-point anchoring of the flange secured by the pin against pulling and by the additional protrusions against rotating is furnished on the spectacle lens and vice versa. A certain flange is suitable for given thicknesses and curvatures of the spectacle lens, because both on the front side and the back side of the spectacle lens it is not the front or back sides that define the gripping surfaces for the connecting element and first protrusion, but the borehole widening.

Abstract: The method checks the plausibility of the signals from the movement sensors and from the course reference unit to compensate for deterministic errors. A Calman filter estimates the stochastic position and direction  errors for calculating corrections to directions and to change of direction. The course reference unit receives the direction corrections whilst the position computer receives the position corrections. Corrected component signals are derived from the said corrections and lie in the north and east directions and are passed to the position computer where they are used to produce signals for the Calman filter.

Abstract: Two optical gratings in conjugate planes of an imaging system are aligned by illuminating one grating (3a) with a laser beam (2) so that the first symmetrical diffraction orders are selected and focused by an imaging system (7) to coincide on a second grating (8a) to be further diffracted thus obtaining second diffraction orders. The phase relationship between the diffracted beams is modulated periodically because the pattern from the second grating is colinear to the optical axis of the imaging system. The relative phase of the second diffraction orders is evaluated. The gratings are linear and parallel to each other alignment in a direction perpendicular of the grating bars.

Abstract: The present invention relates to fire retardant polymer compositions possessing a non-linear structural configuration resulting by the reaction of N-tribromophenylmaleimide, with or without comonomer, with a preformed backbone polymer, in which the bromine content is above 1.2% by weight bromine. The polymer is selected from polystyrene, polyolefins, polyamides, rubbers, polyesters, acrylics, polymeric dienes and mixtures or copolymers thereof. The comonomer present with the N-tribromophenyl. maleimide is selected from the group consisting of acrylonitrile, styrene and vinyl chloride. According to the invention the non-linear structural configurations are obtained either by grafting or crosslinking of the N-tribromophenylmaleimide onto the preformed backbone polymer in the presence of free radicals producing means. Optionally, synergistic fire retardant additives such as antimony oxide are incorporated in the compositions. The preferred compositions will contain above 4% by weight of the total resin present in the compositions. The flame retardant polymer compositions have improved properties compared with those obtained with known flame retardant reagents.
