Abstract: RBRT                        AUTOMOBILE BUMPER     ABSTRACT              A resiliently mounted automobile bumper which 1 effectively absorbs frontal impact shock by compressive deformation of an energy absorbing material, and tilts or skews during oblique and/or bottoming impact, such as the impact which often results during passage over irregular terrain. The bumper is pivotally mounted at either end by a pair of individually pivoting support arms, and spring loaded against a pair of impact arms.  Impact surfaces on the support arms and the impact arms are constructed of an energy absorbing material.  Non-frontal impact pivots the bumper assembly away from the impact arms against the loading springs, and a mechanical governor assembly controls the bumper's return to the static position while assuming proper placement of the impact arms.

Abstract: ABSTRACT OF THE DISCLOSURE:           In the final storage of radioactive substances in containers, these containers must be sealed so as to be gas-tight by means of a cover, before they are taken to the final storage place.  In order to avoid thermal stress, which has up till now been customary, of the radioactive substances on the one hand and of the container and cover on the other hand, it is proposed that the container and the sealing cover should be suitably ground on their seating areas which cooperate with each other, and when the container is closed the cover is held by prestressing on the seating area of the container. In a preferred method, after grinding, a thin equalising layer of a highly corrosion-resistant, deformable material is applied to at least one of the seating surfaces of the container and cover, in order to achieve a compensation for any roughness which may be present, which will improve the sealing, depending on the technically and/or economically possible extent of the grinding.  It is also possible, however, to form the prestressing by means of a lapped contact.

Abstract: ABSTRACT            The diameter of an optical fibre which is being drawn, and possible fluctuations of such diameter, are measured by making the fibre pass between two parallel plates of a capacitor and detecting its capacitance variations due to changes of dielectric constant caused by the passage of the fibre or by diameter variations of the fibre. The magnitude of the diameter or of diameter variations is derived from the capacitance variations.

Abstract: ABSTRACT         A directional drill attached to a drill string having periodic concentric collars is advanced in an inverted arcuate path to form a pilot hole underneath an obstacle followed by a larger concentric washover pipe.  When the washover pipe reaches the surface on the other side of the obstacle a first reamer is attached to the end of the washover pipe exiting the drilling path, a second reamer of smaller diameter than the first reamer is attached to the other end of the first reamer by means providing for some separation between the two reamers, and a production casing of smaller diameter than the second reamer is attached to the other end of the second reamer with a swivel.  The remaining length of the first portion of casing is supported some distance above the ground on rollers located above and beyond the exit point of the pilot hole.  The reamers are operated by rotating the washover pipe and simultaneously drawing the washover pipe through the pilot hole.  As the reamers are drawn through the pilot hole the first reamer enlarges the hole to a diameter greater than that of the casing.  Drilling mud pumped through the washover pipe exits at the reamers to entrain the dislodged earth and the second reamer compacts it to form a bushing around the sides of the enlarged hole to lubricate the passage of the casing. The reaming operation may be performed without the production casing attached to the reamers followed by a second reaming operation with the casing attached in order to complete the installation.

Abstract: ABSTRACT OF THE DISCLOSURE         When measuring a plurality of force components acting upon an object to be measured and based upon forces in a flow-ing medium, it is essential that all of the forces acting upon the object be detected and determined without reactive effect, in order to eliminate, as far as possible, any measuring in-accuracies.  Furthermore, the measuring apparatus, and more particularly the carrier of the object to be measured, must be of simple and compact design, i.e. must take up little space.  According to the invention, this purpose is achieved in that the guide for the object carrier is in the form of a cylinder guided hydrostatically in the mounting system and adapted to move rotatably and longitudinally in the Z-axis, and in that the said cylinder is in communication with both a rotary drive and a device for measuriing the angle of rotation.

Abstract: BI-VERTICAL MAIN DISTRIBUTING FRAME CONNECTOR            Abstract A connector for interconnecting on a telephone central office main frame outside plant wires and central office equipment leads is designed to be attached to two vertical main frame members.  The connector includes two connector units which are abutted in spatial mirror image.   Each connector unit includes a protector field and an adjacent cross-connect field.  The protector field comprises a rectangular connector panel and pin-grip connectors into which are inserted electric protectors of the type having accessible test apertures.  The cross-connect field comprises cross-connect terminals which extend rearward of and forward of a rectangular cross-connect panel.  The cross-connect panel is adjacent to the connector panel but spaced apart in a parallel relationship therewith so that the tips of the cross-connect terminals and the tops of the electric protectors, when inserted in the connector panel, lie in substantially the same plane.          Designation dividers, having prismatic-shaped front portions, separate the protector and cross-connect fields in each connector unit and also the two protector fields in adjacent spatially abutted connector units.  The front facing surfaces of these dividers provide for numerical identification of adjacent cross-connect terminals and electric protectors.  Each unit also includes a fanning strip disposed along the edge of the cross-connect panel for the orderly routing of the jumper wires attached to the cross-connect terminals.  The front edge surface of the fanning strip also provides for the numerical identification of the adjacent cross-connect terminals. The front edge surface of the fanning strip and the intersections of the front facing surfaces of the prismatic designation dividers all lie within the same plane as the tips of the cross-connect terminals and the tops of the electric protectors when inserted in the protector field.

Abstract: ABSTRACT     An opaque reflective print copy is produced by transferring via heat and pressure an electrophotographically formed toner image to a presoftened transparent thermoplastic thin layer carried bonded to an opaque substrate.  The print is formed of at least one generally planar toner image layer embedded in the plastic layer.  Light illuminating the print enters the thin layer and is reflected from the interface between said layer and said substrate, passing through the toner particles as well as being reflected from the toner particles themselves, whereby to provide an image having greater depth intensity and contrast than can be obtained using silver halide photographic film, all without distortion of the image, loss in density or loss in resolution.  The substrate can have a smooth or roughened surface and can be selected from plain or coated paper, metal, stone, stretchable and/or inflatable media as well as irregularly shaped objects.  Successive toner images may be applied superimposed one on the other in layers and in registry by softening the thermoplastic layer after transfer thereto of one toner image and applying the next toner image to the softened layer successively.  The intermediate heating embeds the toner image, transparentizes the image and readies the receptor to receive the next toner image.
