Title: Thermoplastic moulding composition
Inventor: HAMBRECHT JUERGEN DIPL CHEM DR
IPC: C08L25/14
Filed: 1981-10-13
Abstract: The invention relates to a thermoplastic moulding composition comprising a copolymer A and a graft copolymer B. The copolymer A makes up from 50 to 95% by weight of the moulding composition and is built up from a monovinylaromatic monomer and an unsaturated dicarboxylic anhydride as further monomer. The graft copolymer makes up from 5 to 50% by weight of the moulding composition and comprises from 20 to 80% by weight of an elastomeric graft base and from 20 to 80% by weight of a graft shell. The graft shell contains from 80 to 99% by weight of a monovinylaromatic monomer and from 1 to 20% by weight of an ethylenically unsaturated monomer containing at least one reactive terminal group from the series consisting of -OH, -SH and -NHR, where R is H, alkyl having 1 to 18 carbon atoms, aralkyl or aryl. The moulding composition may contain conventional additives and is obtained from a melt of component A with the graft copolymer B by reaction at temperatures of >/=200 DEG C. It is used to produce mouldings.

Title: Turret-head tool holder with several indexing positions for machine tools, in particular for lathes
Inventor: NUZZOLESE MICHELE
IPC: B23Q16/06
Filed: 1981-11-05
Abstract: A turret head for machine tools with several indexing positions is described which has greater rigidity and accuracy and requires less dead time during the transition from one indexing position into another desired indexing position. The turret head requires less space and provides better sealing against the penetration of water, dust or chips into the interior. This turret head consists of a basic body, a tool holder which is rotatably fastened to the basic body, and a piston with an active wedge-shaped end, which piston is displaceably arranged in the tool holder between a first position, in which, with its active wedge-shaped end, it is successively in engagement under the action of flexible means with a multiplicity of corresponding seats, countersunk in a wedge shape and made in a surface of the basic body, and a second position in which it is disengaged. Furthermore, the turret head has a drive member which is rotatably fastened to the basic body coaxially with the tool holder and can be set in rotary motion in both directions by a motor with reversible direction of rotation. An essentially V-shaped groove is made on the side of the drive member. Projecting at the piston is a guide pin which is guided in the groove so that the piston, during rotation of the drive member in both directions, is released from one of the seats countersunk in a wedge shape and then is carried along laterally in both directions, in the course of which it in turn carries along the tool holder for rotation in both directions. In addition, an adjusting bolt is provided which is displaceably arranged in the basic body and can be moved towards and away from the tool holder by the action of suitable actuating means in order successively to snap into a multiplicity of recesses which are made in the tool holder.

Title: Fines conveyor
Inventor: POHLE HELMUT
IPC: B65G25/10
Filed: 1981-11-28
Abstract: Detritus conveyors are used in underground mining and tunnelling, in particular in the area of the conveyor belt transfer points, in order to receive and feed to the outgoing conveyor belt the conveyed-material particles, released from cleaning devices, as well as the collected and deposited dust. To this end, the flights running in a profile trough are designed to be hinged and in such a way that they can be locked in one conveying direction in the perpendicular and are connected to one another via a linkage which is acted upon on one side by a lifting cylinder. The linkage is guided on the lifting cylinder in an elongated hole so that the linkage is displaced by a certain amount during every reciprocating movement and as a result pivots the flights before they are moved in the longitudinal direction of the profile trough. <IMAGE>

Title: Method and device for the measurement of light reflection on the fundus of the eye
Inventor: BIRNGRUBER REGINALD DIPL PHYS
IPC: A61B3/125
Filed: 1982-07-28
Abstract: The method and the device for the measurement of light reflection on fundus of the the eye permit measurement of a luminance via the multiple reflection at the eye interior in the plane of the pupil which corresponds to the reflection of light from an irradiated site on the fundus of the eye. Such measurements can be particularly used for the operation of photocoagulators of the fundus of the eye and simplify the measurement very considerably as compared to the conventional method in which the luminance at the fundus of the eye is measured in an optical intermediate image plane. Figure 1 shows an exemplary embodiment of the measurement apparatus in which a photodetector (P) is integrated in a contact optical device (K) placed on the cornea of the eye (A). <IMAGE>

Title: Scroll spring element
Inventor: ALBERSINGER GEORG
IPC: F16F1/54
Filed: 1983-02-17
Abstract: The scroll spring element is characterised by wide-ranging possibilities for use and design with both a linear and a rotating movement direction. It is comparable to the greatest possible extent with the conventionally known rubber-metal connections, the spring elements, however, not being incorporated non-detachably, for example by means of vulcanisation, but operating in a rolling manner, as round roller bodies, between in each case two surfaces which are arranged parallel to one another. This has the advantage that large spring movements can be achieved with a high load capability, with a spring characteristic which can be designed as required, with a small structural size, and at a low production cost. The spring roller bodies can be produced from different elastic materials. The use of the scroll spring element for example as a torsionally-elastic shaft coupling appears to be particularly advantageous.

Title: Clutchless transport device for film transport in two directions
Inventor: HALEWIJN HARRY JOHN
IPC: B65H23/192
Filed: 1983-03-09
Abstract: The subject matter of the invention is a device, which conveys in two mutually opposite directions, for transporting films or film-like material. The device includes an upper plate (6) and a lower plate (7) which delimits a gap (8) through which the film (9) is transported. Corresponding gaps (12, 13) are formed between the two rollers of in each case one pair (1, 2) of transport rollers at both ends of the gap (8) between the plates (6, 7) in such a way that they align with the gap between the plates. The rollers of the pairs (1, 2) of rollers are driven by a common motor (4) in such a way that the ratio of the speeds of the rollers of the two pairs of rollers is constant. The plates (6, 7) prevent the formation of corrugations in the film, so that the film is completely plane where the image is applied. The invention provides a simple arrangement in which clutches, such as are required to be present in known devices in order to prevent impermissible tensioning of the film, are dispensible. Provided parallel to the film advance are side walls which hold the plates (6, 7) at a distance from one another and at the same time prevent the film from tipping in the edge region when use is made of rollers which are short in relation to the film width in the direction of the film width. <IMAGE>

Title: Process for producing optically readable information carriers in disk form
Inventor: LANGOWSKI HORST-CHRISTIAN DIPL
IPC: G11B7/254
Filed: 1984-08-02
Abstract: Optical information storage disks are usually read by means of a laser beam in reflection. For this purpose, the microstructure containing the information, impressed in at least one side of the information carrier disk, has to be provided with a reflective layer which has adequate reflectivity for the laser beam at the same time as good adhesion and corrosion resistance. Furthermore, the reflective layer must be additionally covered by a protective layer for protecting the information microstructure and the reflective layer. In order to reduce considerably the costs for the production equipment, it is proposed to simplify the production process on the one hand for the reflective layer and on the other hand for the protective layer by using the same production technology, i.e. applying the two layers to the disks (P) one after the other in a sputtering installation (SP) and using here as the material for the protective layer either a corrosion-resistant metal or a suitable dielectric (Al2O3, SiO2). <IMAGE>
