Abstract: CONTROL FOR REMOTE CONTROL WIRING SYSTEM                 ABSTRACT OF THE DISCLOSURE A remote control wiring system is provided which includes a transformer for providing power to a low voltage subsystem which, through relays, controls the opening and closing of higher voltage load circuits of the remote control wiring system.  A plurality of relays are provided, one for controlling each of the load circuits.  A first circuit in-cludes in series a first solid state switching device, such as a suitable transistor, SCR or triac, and a relay, or a plurality of relays connected in parallel.  Similarly, a second circuit includes in series a second solid state switch-ing device, such as a suitable transistor, SCR or triac, and the relay, or the plurality of relays connected in parallel. A two-position switch is incorporated in the low voltage subsystem in association with the first and second circuits. In one position of the switch the first circuit is closed through the first solid state switching device to energize the aforementioned relay or relays for closing the load circuit or circuits associated therewith.  In a second position of the switch the second circuit is closed through the second solid state switching device to energize the relay or relays for opening the load circuit or circuits.

Abstract: DISPENSER FOR VAPORIZABLE MATERIAL   ACCENTUATED BY AMBIENT AIR FLOW                      Abstract of the Disclosure A dispenser is provided for vaporizable materials such as deodorants and insecticides.  The dispenser is adapted to create accentuated air flow over the materials either in the presence of ambient air flow or when the dispenser is moved through the air, for example, by being mounted on the back of a door.  It dispenses far smaller quantities in the absence of air movement.     The dispenser includes one or more material containers open at one end and mounted within a vented housing.  The vents on the housing are positioned over a portion of the open end of the con-tained material, and are recessed in a concave area of the housing.          The housing is spaced from the material container and has exit ports along its periphery.  The containers preferably have a dividing partition passing part way down the material container to provide paths for the air to flow down one side and up on the other for better contact with the vaporizable material.  The re-sult is that relative motion between the dispenser and the ambient air creates one-way air flow pattern into the central ports, across the vaporizable material, and out the back of the unit.     The unit is mounted in a place where it will periodically be moved, such as on a door, or where it would be subject to periodic air flows, such as on the wall adjacent a door.

Abstract: MULTI-PORTAL RADIO FREQUENCY GENERATOR Abstract A unique apparatus for multi-portal ad-ministration of radio frequency range electro-magnetic energy for therapeutic treatment of inte-rior portions of various substrates including ani-mals and humans which comprises an R.F. signal gene-rator which is connected to a timer component having switching logic to apply R.F. electromagnetic energy one set at a time, sequentially across a plurality of sets of paired electrode plates, i.e., applicators. Each set of paired electrode plates is positioned on a different axis with reference to a fixed central point located between the plates at which such axes approximately intersect and which is the location of the portion to be treated. The apparatus permits a fixed target, i.e., portion to be treated, to receive a constant input of R.F. energy although such energy is coming from different directions and emanating from different electrodes, hence several R.F. fields are created sequentially by the control mechanism as it functions.

Abstract: Abstract of the Disclosure Self-twist plural yarn strands are produced by a system wherein at least two singles yarn strands are individually twisted to form twisted strands each having longitudinally spaced nodes and strands are brought together in a parallel relationship with the nodes of one strand substantially aligned with the nodes of each other strand.  The corresponding nodes from one strand are fastened to those of each other strand, and the strands are allowed to ply.  The nodes fastening means comprises a rotating member having a contact surface for fastening the nodes by gathering and twisting of the fibers from one strand with those of another strand at the nodes of each respective strand.  Ply yarn twist uniformity is assured through the use of improved twist insertion jets, together with a means for holding singles yarn separate to allow longitudinal levelling of singles yarn torque prior to plying.

Abstract: ABSTRACT OF THE DISCLOSURE          An electromagnetic arc extinction apparatus for switchgear comprises an arc chamber made of an electrically insulating material and having an axial channel.  There are two electrodes arranged in axial relationship to the axis of the arc chamber and adapted to form an arc having a helical shape.  To provide for movement of the arc in a radial direction, the arc chamber defines a helical cavity whose pitch is at least 10 times smaller than the diameter of the arc chamber measured over its cross-section.  In the apparatus of the invention, the helical arc has a small pitch with the result that the associated switchgear offers small overall dimensions and can handle high voltages.

Abstract: SURGE SUPPRESSION               ABSTRACT OF THE DISCLOSURE           A surge suppression system for dampening surge pressures or pipe hammer by introducing a gas into a flow conduit in such an amount that the introduced gas is in excess of that required to saturate the liquid.  Preferably, the gases are those which are relatively inert or not unduly reactive and which posses relatively low saturation levels with respect to the liquid.  Desirably, the gas is added through a member to the flow conduit in a vicinity of high tubulence.  The surge suppression system can be utilized in generally any liquid system and particularly in a liquid transmission system.             Another embodiment pertains to a scrubber or washer for generally purifying gases and may contain one or two stages to efficient-ly remove impurities as through the use of high solubility fluids, fluids which decompose contaminants or which contain or provide (i.e heating stage) catalysts to decompose contaminants, oxidizing agents, or re-ducing agents.  The scrubber contains a packed bed and the packing may be characterized as one where the inside hydraulic radius equals the hydraulic radius of the external flow channels.  The washer or scrubber type apparatus is particularly suitable for treating (purifying) materials such as ozone utilized in a deodorizing or disinfecting system.
