Abstract: ABSTRACT OF THE DISCLOSURE             A railway vehicle of modular construction in which the interchangeably positioned units include a fuel tank/cab unit, a control-equipment unit, a prime mover unit with a die-sel, engine and an electric generator or hydraulic pump, and a cooling unit, all having bottom plates corresponding in width to the width of the frame.  The units are mounted on the lon-gitudinal beams of the upwardly open frame by bridge plates or yokes which draw bridged pairs of bottom plates toward the longitudinal beams.  The spaces between the upper surfaces of the longitudinal beams and the upper surface of the transverse beams accommodates a cooling-air duct running to the trucks from the cooling unit which can also cool the engine.

Abstract: ABSTRACT OF THE DISCLOSURE            The process uses the temperature coefficient of the copper resistance of the oscillating coil  for compensating the temperature coefficient of the quality factor of the same oscillating coil. To this end, a voltage proportional to the copper resistance of the oscillating coil is injected into the oscillating circuit. The oscillator according to the process comprises an oscillating coil which is executed with a high frequency litz wire. In order to access the copper resistance of the coil one of the litz wires is separated from the other wire at a first terminal of the coil and separately connected to a second terminal of this coil. From this second terminal, the coil is seen as a bifilar coil. A constant alternating current source is connected to the second terminal in order to inject into the oscillating circuit a voltage proportional to the copper resistance of the coil. The oscillator is preferably used  for proximity switches having  a great switching distance.

Abstract: PROCEDURES FOR PREPARING COMPOSITE MATERIALS FROM COLLAGEN AND GLYCOSAMINOGLYCAN                       Abstract This invention relates to crosslinked collagen and glycosaminoglycan materials, and to procedures for preparing such materials.  It has been discovered that if collagen fibrils in an aqueous acidic solution are contacted with a crosslinking agent before being contacted with glycosaminoglycan, the materials produced have extremely low levels of thrombogenicity. Such materials are well suited for in-dwelling catheters, blood vessel grafts, and other devices that are in continuous contact with blood for long periods of time.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention is directed to a shearing machine comprising a frame member having a throat, first upper and lower blades, second upper and lower blades and a ram member for carrying the first and second upper blades. The first upper and lower blades are connected at right angles to the second upper and lower blades, respectively. The shearing edge of the first upper blade is originally so inclined as to ascend from its free end toward the intersecting point where the shearing edges of the first and second upper blades intersect or are connected with each other at the right angle. Also, the shearing edge of the second upper blade is originally so inclined as to descend from the intersecting point toward its free end. The ram member is pivotally connected to the frame member by means of a pivot means so as to be rotated or swung up and down thereon by a drive means. The pivot means is horizontally coupled to the frame member at a location spaced upwardly from the level of the first and second lower blades so that the shearing edge of the second upper blade may be inclined with its free end located higher than the intersecting point when the ram member is lowered. Also, the second upper and lower blades are so disposed as to be located outside of the vertical plane of the outer side of the frame member to protrude outwardly therefrom together with the ends of the first upper and lower blades connected to the intersecting point.

The rear wheel steering means includes a crank member connected to the steering wheel, a movable member connected to the crank member, a restriction means for restraining the movable member and  permitting the latter to perform only restricted movements along a predetermined pattern, and an output mechanism interconnecting the movable member and the rear wheel for effecting the steering of the rear wheel according to motional components in a predetermined direction of such restricted movements.    A vehicular steering system capable of steering front and rear wheels in the same direction in response to relatively small steering amounts of a steering wheel and in opposite directions in response to relatively large steering amounts of the steering wheel, is provided by a novel, compact construction.

Abstract: METHOD FOR MAKING HOLOGRAPHIC OPTICAL   ELEMENTS WITH HIGH DIFFRACTION        EFFICIENCIES                       Abstract Production quantities of a multi-element holographic scanner disc are made by optically replicating a silver halide master disc one element at a time in a dichromated gelatin film. The dichromated gelatin film swells during pro-cessing.  The swell is monitored during production by determining the shift in the angle of the Bragg surfaces within the gel.  The angle of the repli-cating beam for each element is changed from that of the original reference beam to establish a Bragg angle at exposure which will be tilted to the pro-per angle after swelling in order to maximize the diffraction efficiency of the element at the original reference beam angle.

Abstract: APPLICATION OF              COLLIER M. MILLER AND ROBERT SCHMITZ                            ROTARY VALVE   ABSTRACT A rotary valve has a valve body with a pair of fluid ports providing fluid exits on a face of the valve body.  The fluid ports are connected to corresponding fluid channels in the valve body extending between the fluid ports and fluid inlet connections to the valve body.  A fluid control plate is positioned in contact with the face of the valve body and extends across the fluid ports.  The control plate has a fluid channel therein which is dimensioned to extend between the fluid ports in one position of the valve plate.  The valve plate is axially mounted on an output shaft of a drive motor which is connected to the valve plate by a coupling shaft.  The face of the valve body and the contacting face of the valve plates are ground precisely flat and after hard anodizing are coated with a low friction coating such as  molydisulphide . The motor is arranged to urge the valve plate parallel to and against the face of the valve body by the weight of the motor and the connecting elements between the motor and the valve. The low friction coating allows a rotation of the valve plate on the valve body while providing a fluid seal therebetween to confine the fluid to the ports and channels.

Abstract: ABSTRACT OF THE DISCLOSURE        There is disclosed a type of riser to connect subsea hydrocarbon production equipment to a floating storage, process or control facility which combines the advantages of integral and non-integral risers previously used.  This is achieved by a locking mechanism which allows the individual tubes to be freed once each section of riser is added, and a subsea remotely operated connector that allows individual tubing to be released.  Improvements in the design of collet connectors are also disclosed.  There is also disclosed a guidelineless method of connecting risers or other equipment to subsea installations.  The method uses a cone on the subsea equipment and a guideframe on the riser.  The guide-frame aligns itself with the subsea cone prior to the riser being connected.  As the riser is drawn to the subsea mandrel the guideframe aligns the riser connector with the mandrel.          A still further embodiment disclosed herein is a flexjoint consisting of a series of flexjoints in an outer case with a high pressure tube inside.  Internal tubes are fixed at either end of the assembly to the outer case.
