Abstract: ABSTRACT OF THE DISCLOSURE   There is disclosed a method for the preparation of a homogeneous, physically stable dispersion of colloidal metal particles of a transition metal selected from the group consisting of ruthenium, rhodium, osmium and iridium, having a size in the range of from about 10 Angstrom units to about 200 Angstrom units. The method comprises preparing a solution of a functional polymer in an inert solvent, and incrementally adding thereto a transition metal cluster compound at a temperature at which the transition metal cluster compound will become bound to the polymer and thermally decompose to produce elemental transition metal particles, the process being carried out in an inert atmosphere. Such dispersions may be used per se as catalysts, or may be used for the preparation of supported colloidal transition metal catalysts. The dispersions may also be used for the preparation of ablative optical recording media.

Abstract: ABSTRACT OF THE DISCLOSURE:     Device intended to be displaced along the track of rails and comprising a frame guided by the rail provided with a grinding wheel working through its periphery. To uniformly distribute its wearing through the rail on all its active surface, the grinding wheel is driven, on top of its continuous rotative movement obtained through a driving motor, in an alternative movement transversal to the track by means of an actuating mechanism.  This actuating mechanism comprises a motorgear assembly driving an eccentric shaft on the exentric of which the movable support is hinged.  To avoid the formation of sinusoidal traces due to the grinding the amplitude a of the reciprocal movement is linked by a relation a ? l-f to the width l of the active surface of the grinding wheel and to the width f of the portion of the profile of the rail which is ground.

Abstract: ABSTRACT OF THE DISCLOSURE          The present invention refers to a method and a device for recording, handing and documentation of time/ activity data.  The duration of different categories of work occasions and/or activities, as for example down time, can be measured by activation of a press button corresp-ondant to each category of work.  Hereby a pulse train, generated in a pulse generator, is provided to at least one of a plurality of possible storage cells.  As the time between two pulses, following after each other, is constant and known, e.g. one hundredth of an hour, the total number of pulses, the storage cells are fed with, will correspond to a time value required for the respective output of work and/or activity.  When desired the information content of all storage cells is read. This information is converted and/or handled at which the result by a printer  is written in a manually readable form on an information carrier.  The information content of the storage cells can also  be transferred to and handled by a central reading unit.

Abstract: ABSTRACT OF THE DISCLOSURE        A material web impregnated with a settable synthetic resin travels in vertical direction, from the bottom towards the top, through a first heat treatment zone where the solvent of the synthetic resin or plastic is evaporated and a chemical reaction is initiated. The tacky material web departing from the first heat or thermal treatment zone then passes through a cooling zone where it is cooled by means of a cooling medium to such a degree that the chemical reaction and tackiness is freezed. After deflection of the material web the latter is moved in vertical direction downwardly through a second heat treatment zone where the chemical reaction proceeds. By in-corporating a cooling zone between the first heat treatment zone and the deflection rolls the material web can be moved at greater velocities through the second heat treatment zone in which the heat treatment can be controlled in optimal manner due to the web entering this zone in a well defined state. Prior to winding-up of the material web the latter is again cooled.

Abstract: III. Abstract This invention relates to the inlet throat of a machine for forming large round bales of fibrous agricultural material.  The machine includes a single axle chassis and a tongue enabling it to be towed along a windrow by a tractor. On top of the chassis is a generally cylindrical housing con-taining a baling chamber of fixed size having a horizontal axis.  Around the periphery of the baling chamber is a plurality of serially arranged conveying elements.  The rear portion of the housing swings upward from a hinge point at the top to enable rearward discharge of a completed bale.  A pickup mechanism is transversely mounted across the lower front of the chassis.  Behind the topside of the pickup mechanism there is a conveyor which forms the bottom of the front part of the baling zone.  The conveyor consists of a plurality of side-by-side belts entrained on four parallel rollers which extend horizontally across the entire bottom of the machine. The rollers are fixedly journalled to the housing frame with the three rearmost rollers being generally on the circum-ference of the baling zone and the front roller positioned such that a plane tangent with the top of both the pickup reel and the top of the middle roller will also pass tangen-tially across the top of the front roller.

Abstract: ABSTRACT OF THE DISCLOSURE      The activation of a mass of metal granules capable of storing hydrogen with the formation of hydride in a pressure vessel, instead of having to be activated before use by repeated heating in a hydrogen atmosphere followed by cooling and evacuation before the next heating, is activated in the pressure vessel used for storage by first heating a small portion of the granulate to the necessary activation temperature and then allowing the heat developed by the activation of that portion to produce the activation of the remainder of the granulate.  It is found that it thus is possible to provide complete activation with only one heating step.  The small portion that is first activated may be a part of the granulate that is of a different compos-ition that is easier to activate, for example, LaNi5, which can be activated at room temperature, or iron-titanium alloys that are capable of activation under 100°C.  Alternatively, the entire mass of granulate may be selected for its hydrogen-storage capability rather than its ease of activation and a small part thereof can be activated first by means of a high temperature (up to 800°C) generated in a very small source of heat, as by a platinum wire electric heater, turned on for only 10 or 20 minutes, after which the activation produced provides enough heat for activating the remainder of the granular material.

Abstract: RF SHIELDED DOOR SEAL                              ABSTRACT        A door seal for a room shielded against electromagnetic radiation in which the door is mounted on a frame to move between open and closed positions.  The door may be slidable or hinged. The door seal is formed of peripheral flexible plates that are welded together on their outer edges.  Spaced between the plates and between the frame and the door there is a peripheral tubular bladder which when expanded with compressed air, for example, forces the plates outwardly against the door and the frame to form a seal.  A seal is also formed within the plates by the bladder forced thereagainst. There are a series of peripherally spaced magnets adapted to hold the door sealing plate away from the door, when the bladder is not expanded.  When the bladder is expanded, the plate is moved off of the magnets by the force of the expanding bladder.  The force of the magnets on the plate Is rendered ineffective as the bladder moves the plate away from the magnets and the effectiveness of the magnetic force is sub-stantially increased as the bladder is unexpanded so that the plate is allowed to be withdrawn from the door by the force of the magnets.

Abstract: TREE RESISTANT POWER CABLE Abstract An improved method and apparatus for fabricating insulated cables, particularly polymeric insulated electrical power cables, resistant to the formation and growth of electrochemical trees is disclosed.  Internal pressure on the conductor side of the cable when it is maintained lower than the external pressure on the outer surface of the insulation during extrusion.  Extrusion pressure higher than the external pressure results in expansion of the insulation following extrusion   This expansion or swelling reduces the number and size of cracks and voids which are pre-cursors of electrochemical trees.  In addition, pressure curing the extruded, insulated cable with a curing medium above its melting point followed by gradual gradient cooling under internal pressure and higher external cooling fluid pressure to around room temperature optimizes the resistance of the cable to nucleation and growth of electrochemical trees.
