Abstract: METALLIC WIRING BOX                 Abstract of the Disclosure An electrical wiring box structure comprises a formed metal box structure having first and second endwalls, first and second sidewalls, and a rear wall interconnected to form a chamber for receiving a wiring device.  A wiring device mounting portion is provided as a part of the endwalls of the box or, in an alternative embodiment, as a member comprising a flat leg portion adapted to lie along the inside surface of the box endwall and adapted to be secured to the box endwall.  A wiring device mounting portion of the member is formed substantially at right angles to the leg portion, and extends outwardly from the box endwall.  An H-shaped cut in the mounting portion divides the portion into opposed, flexible tab portions which terminate in screw-engaging tips, spaced apart by a distance less than the outside diameter of the wiring device mounting screw.  Insertion of the mounting screw between the flexible tabs deflects the tabs downward and apart from one another to permit the facile push-insertion of the screw into the mounting member.  Turning the mounting screw draws the tab portions upward and together to firmly engage the wiring device mount screw.

Abstract: Abstract Control Mechanism for Operating a Tractor A control mechanism associated with a tractor operators seat and an arm rest is disclosed which includes a steering selector apparatus having an upstanding member and a tiller arm extending outwardly therefrom.  The tiller arm is advantageously located immediately forwardly of the arm rest and has a mounting portion and hand grip portion that can be easily grasped by an operator's downwardly facing hand palm.  A support assembly pivotally supports the upstanding member for movement about a fixed upstanding axis and a control device steers the tractor in response to the swinging movement of the tiller arm.          In response to rotation of the hand grip portion about the axis of the tiller arm a second control device effects a change in the gear condition of an associated transmission.

Abstract: Title of the Invention:         MONOMERIC VINYL CHLORIDE STRIPPING TOWER            Abstract of the Disclosure:           Disclosed herein is a stripping tower adapted to remove unreacted vinyl chloride from a suspension or emulsion of a vinyl chloride resin after its polymerization reaction.          The tower is a packed tower filled with a packing such as Tellerette packing.  A condenser is provided in direct attachment to a top portion of the packed tower so that steam, which is discharged together with stripped monomeric vinyl chloride gas, is condensed in the condenser, separated from the monomeric vinyl chloride gas and then recirculated to the packed tower.  Use of a packed tower as a stripping tower and steam as a stripping medium enjoys good removal efficiency of monomeric vinyl chloride but is accompanied by occurrence of a large volume of foams of a polyvinyl chloride slurry in the tower.  Foams of the slurry eventually overflow from the top of the tower and do not permit any further continuation of the operation.  Provision of the condenser in direct   attachment to    the top portion of the tower was found to be effective in suppressing the occurrence of foams, thereby permitting efficient removal of monomeric vinyl chloride.

Abstract: SOLAR SELECTIVE SURFACE COATING            ABSTRACT OF THE DISCLOSURE          A solar collector element having an inner tube through which a fluid can be passed, an outer glass tube enveloping the periphery of the inner tube and defining an evacuated space between the two tubes, and a solar selective surface coating deposited on the outer surface of the inner tube.  The surface coating is deposited as three layers, an inner layer composed of a metal which exhibits high reflectivity in the infra-red spectral range, an outer layer composed of a material which behaves as a semiconductor at collector operating temperatures and an intermediate layer which is composed of a dielectric material.  The materials of the respective layers are selected such that the refractive index mismatch between the inner layer and the intermediate layer is greater than it would be between the inner layer and the outer layer, in the absence of the intermediate layer, whereby the infra-red emittance of the collector element is reduced relative to that of an equivalent collector element having a two-layer selective surface coating.

Abstract: ABSTRACT          In an arrangement for forming rolls from a running web, the web is slit in its longitudinal direction and  wound into a plurality of rolls,  all having the same rotation direction during winding. The arrangement comprises means providing a peripheral as well as a central roll support force acting on the rolls during winding. The arrangement is so dimensioned that,  due  to  the  increase  of  the  roll  diameter  during winding,  the ratio of the peripheral support force and the central  support  force  of  a  roll  undergoes  a  substantial change merely as a  result  of  the  geometrial  construction features  of  the  arrangement.  In  the  final  phase  of  the winding of a roll, the central support force of the roll is considerably higher than the peripheral support force of the roll.
