Abstract: Rail clip driving apparatus ABSTRACT OF THE DISCLOSURE          There is disclosed a trolley which runs along unfastened rails  of  a     track, in which each rail is positioned between a respective one of two pairs of housings on each sleeper, the trolley moving from sleeper to sleeper in order to complete permanent fastening of the rails to the sleepers.  The trolley has a pair of rail-clip driving apparatus on each side, one associated with each rail, of which each comprise a pair of magazines for storing e-shaped clips, and a clip driver for each magazine which drives a lowermost clip in a stack of clips in the magazine into a sleeper housing.  Each apparatus includes a longitudinally displaceable support tube on which the magazines are mounted , the tube moving one way or the other  depending upon which magazine first comes into cooperation with its respective housing in order to bring the other magazine into cooperation with its housing.          The apparatus may move laterally relative to the trolley via a pair of parallelogram linkages provided one at each end of the support tube in order to adjust the apparatus to a changing path of the rails.  A sleeper lifter may be provided to raise sleepers which are too low, and a sleeper sensor responds to the presence of a metallic housing on a sleeper in order to stop the trolley as it advances from sleeper to sleeper.

Abstract: LAMP DIMMER          Abstract of the Disclosure A lamp dimmer suited for fluorescent and other lamps which controllably notches the applied voltage to a lamp circuit each half cycle.  Progressively larger dimming control voltages produces progressively wider notches as well as progressively causing the notches to be further from the zero-crossing occurrence toward the peak occurrence of the half cycles, thereby providing means for varying power to the light circuit.  Optocoupler means is employed with respect to a power output bridge to isolate the control circuit from the power output circuit to the lamp.  A photosensor used to sense the ambient light conditions is used to produce the dimming control voltage so as to achieve a balancing effect between the ambient and the artificial light produced by the lamp.

Abstract: ABSTRACT OF THE DISCLOSURE             Low temperature discharge of particulate material from a hopper or the like is facilitated by coating the hopper walls with a water solution of an inorganic freeze point depressant, the solution having a freezing point below  about -20°C. and being thickened by the addition thereto of a compatible thickening agent, whereby the substance can be readily applied to the wall and will remain in position on the wall. When the substance is to be used to coat steel or aluminum walls the pH of the substance is modified if necessary to prevent corrosion of the wall without adversely affecting the viscosity of the substance.

Abstract: ABSTRACT       A gun for dispensing a plural component system includes a housing having appropriate connections to a pressurized air supply and pressurized first and second component storage reservoirs.  Within the housing are located first and second component feed ports, each having a control valve located in its interior.  A valve carrier member is movably located in the housing and is moved by a trigger. The first and the second valves are connected to and moved in response to movement of the valve carrier member. The gun includes a gas passage having a valve located therein. The gas valve is also connected to and moves in response to the valve carrier.  At the forward end of the housing is a static mixing chamber which has a discharge outlet as well as inlets leading to both of the component feed ports and to the air passage.  When the valve carrier is in a first position pressurized air is introduced into the mixing chamber which purges the mixing chamber.  When the valve carrier is in a second position the components of the plural component system are discharged from the respective component feed ports into the mixing chamber and out of the discharge outlet.

Abstract: ABSTRACT:          Medical apparatus A medical apparatus comprising a displaceable vertical column 1 along which there can be slid a support 23 in which an arm 25 is rota-table about a first horizontal axis. Secured to the arm 25 and rotatable about a second horizontal axis parallel to the first horizontal axis, is an examination device which comprises a combination of a radiation source 81 and a radiation detector 83. Said combination is mounted on a C-shaped frame 63 which is displaceable circumferentially about an axis which lies at right angles to both horizontal axes. The two translatory dis-placements and the three rotary displacements of the apparatus can be per-formed individually by means of corresponding variable speed motor drives whose operation can, however, be coordinated if desired.         The medical apparatus is particulary suitable for so-called isocentric examinations of the vascular system.   Figure 1.

Abstract: ABSTRACT   An improved method and apparatus for storing isotopes of hydrogen (especially tritium) are provided.  The hydro-gen gas(es) is (are) stored as hydrides of material (for example uranium) within boreholes in a block of copper.          The mass of the block is critically important to the oper-ation, as is the selection of copper, because no cooling pipes are used.  Because no cooling pipes are used, there can be no failure due to cooling pipes.  And because cop-per is used instead of stainless steel, a significantly higher temperature can be reached before the eutectic for-mation of uranium with copper occurs, (the eutectic of uranium with the iron in stainless steel forming at a sig-nificantly lower temperature).
