It has been suggested that it is very important to position patients reproducibly at different stages of radiotherapy treatment planning and treatment, or similar procedures. Devices have been described for positioning a patient's upper and lower thorax. This invention provides reproducible positioning for a female patient's breasts, for example in planning treatment of and treating breast tumours...

{PG,1 A supply package for wet-impregnated multifilament roving is provided in which the multifilament roving is impregnated with a curable liquid having a tack less than about 6 (measured on a Thwing-Albert inkometer) in an amount at least sufficient to fill the spaces between the filaments in the roving, but not in excess of about a 3:2 ratio of curable liquid to fiber, by volume. This impregnat...

The yarn to be transferred is fed at high speed through a traverse mechanism and between a drive roll and a bobbin mounted on a first chuck and rotated by the drive roll to cross-wind a yarn package. An empty bobbin is mounted on a second chuck parallel to the first chuck. When the package is substantially full wound, the empty bobbin is engaged with the drive roll and the yarn package is retracte...

L'invention concerne d'une part un appareillage à rayonnement LASZE comportant un moyen (30) pour produire une fréquence de sortie qui est la 2ème harmonique de la fréquence fondamentale du LASER et une lentille de focalisation (46) à distance focale peu élevée. L'invensité énergétique peut encore etre réglée par un dispositif d'atténuation (32). En fonctionnement, le diamant (54) est monté sur un...

A shape-forming apparatus (10) for carcases of radial tyres is described. In the shape-forming apparatus (10) the expansion of the forming apparatus is exactly controlled by a central, expandable bellows (16) in which a narrow section of the, in the axial direction, central region of the forming apparatus starts the expansion. Preferably an arrangement of wires (17) extending in the axial directio...

In a data processing apparatus, a device for reading data stored in a card is provided with a housing having a slit through which the card can be manually inserted and engaged by guides within the housing for movement in a predetermined path to an operative position, a slider member movable within the housing and having a portion interposed in the path of the card so as to be engaged by the latter...

A polyester film especially suitable for use as the base film for magnetic recording media provided with excellent slipperiness, flatness, slidability and durability can be manufactured by endowing a polyester film with surface conditions represented by a formula Ra >/= 2 x 10<-4>.H2 + 0.008, wherein Ra is the average roughness ( mu m) and H2 is the number of the secondary interference fringes mea...

1. Apparatus for welding thermoplastic articles by means of a filler material, with an advancing facility for the filler material, an adjoining heating chamber in the internal part of which a melting channel is arranged for the plasticizing of the filler material, characterized in that the melting channel (34) consists of several bores (38, 42) running in parallel and being connected with each oth...

The present invention relates to moldings, particularly in the form of cushioning elements, of at least partly open-cell polyurethane elastomers which have a substantially homogeneous density profile and a density of from 0.3 to 0.8 g/cc and which are characterized in that their surface is sealed by a continuous, tight, nonporous skin of polyurethane or polyurethane urea having a thickness of from...

This toe-fitting for safety ski binding is of the type intended for operating in conjunction with a boot supporting device and includes a boot supporting plate movable across the ski and adapted, during its movement, to cause through a cam mechanism the translation along the ski axis of a slide controlling the release spring in order to reduce the resistance thereof to the ski boot release movemen...

PCT No. PCT/EP79/00008 Sec. 371 Date Oct. 6, 1979 Sec. 102(e) Date Oct. 5, 1979 PCT Filed Feb. 6, 1979 PCT Pub. No. WO79/00591 PCT Pub. Date Aug. 23, 1979. In a safety ski binding, a sole plate secured against lifting off is rotatably mounted on the ski surface in the heel region of the ski boot on a pivot extending perpendicular to the ski surface. The sole plate has a toe holder at its front end...

In order to improve the accuracy of borehole survey systems utilizing probes with inertial components including inclinometers, two ring laser gyro units are included to provide rotation information 56, 58 to the system. When the probe is moving in a borehole, inclinometer information 50, 52, 54 is used 78 to produce a synthetic rotation signal 80 to take the place of a third gyro and the earth's r...

The invention relates to a sound-damping element (1), in the outer layers (3, 5) of which U-profiles (6-11) are inserted. The U-profiles (6-11), preferably made of steel, increase the sound-damping value of the element from 39 dB to 44 dB. Gluing the U-profiles (6-11) into the outer layers (3, 5) of the element moreover ensures better rigidity of the element (1).

Certain phenolic cellular materials of low thermal conductivity can be produced by having in the cells of the cellular material a synergistic mixture of trichlorofluoromethane and 1,1,2-trichloro-1,2,2-trifluoro-ethane in a molar ratio of 1:20 to 20:1.
