Abstract: SMOKESTACK EMISSION CONTROL APPARATUS            Abstract of the Disclosure A smokestack emissions control device is mounted to a smokestack, or the like,  to clean and cool the emissions from the stack.   The apparatus includes a housing shaped to be mounted on top of an emission stack and has a liquid tank formed in the housing for supporting a liquid therein.   The tank is mounted directly in the passageway of escaping emissions to force the emissions through the liquid.  A tank baffle extends into the liquid tank and into a liquid therein to force the escaping emissions from the smokestack through the liquid.  A reduced pressure chamber  is located adjacent  to the liquid tank  to create a negative pressure on one side of the liquid in the tank to draw the smokestack emissions through the liquid.  A separator is located near the base of the stack with pipes connecting the separator to the liquid  bath for circulating the liquid in the liquid tank.   The  liquid  in  the bath can be  specially formulated  for the particular emissions  from the emission stack.  Anti foaming and bubbling means are included to prevent the liquid from foaming out of the tank.  The tank is lightweight and allows the entire apparatus to be placed on an existing exhaust stack.

Abstract: ABSTRACT  AUTOMATIC TOOLCHANGER TAPPING LUBRICANT DISPENSER         A tapping lubricant dispenser apparatus is provided for use in numerically controlled automatic toolchanger machining systems to dispense tapping lubricant into a prev-iously drilled hole before tapping.  The tapping lubricant is usually a viscous tapping compound of the consistency of paste, grease or the like.  The apparatus includes a tool-holder of the type to fit into the machine spindle, a reser-voir for a supply of lubricant -- typically sufficient to run unattended for several complete cycles, e.g. at least one shift -- and a reciprocating pump means that dispenses the lubricant responsive to actuation by the numerical control system when the toolholder of this apparatus is fitted into the machine tool spindle.  The reservoir reloads the pump after each dispensing action.  The numerical control and toolchanger system is programmed to select the apparatus, put it in the spindle, align same with the hole to be tapped, and causes pump reciprocation and dispensing and then remove the apparatus from the spindle.  Usually a drilling program is employed whereby the motion to advance the drill into a hole instead advances this apparatus thereby placing in the hole a body of lubricant.

Abstract: PHOTOGRAPHIC ELEMENT AND PROCESS UTILIZING METAL COMPLEX COLOR MASKING DYES Abstract of the Disclosure A process of obtaining highly stable color masking dyes comprises use of an element which has a support having thereon at least one silver halide emulsion layer having associated therewith an essentially colorless, immobile, ligand-releasing compound of the structure LIG-X.  In this structure, X is a group which, as a function of silver halide development, is cleaved from LIG, and LIG is a ligand capable of complexing with metal ions while joined to X to form a color masking dye.  A color masking dye is formed by developing the imagewise exposed areas of the described element with a developing agent to cleave LIG from X and washing substantially all of the cleaved LIG moieties in those areas out of the element, and treating the element with metal ions to form a masking dye complex with LIG-X in unexposed areas.

Abstract: ABSTRACT OF THE DISCLOSURE      A pneumatically operated reciprocating three-way valve having particular application to a double diaphragm pump.  The valve is operative without a lubricating oil mist or the inef-ficiency resulting from air leakage between the valve piston and cylinder.  Sticking and stalling of the valve piston are pre-vented by deformation of the cylinder under pressure to provide leakage of selected cavities within the valve.  The pump also avoids the use of a deicer mist by an adjustable bleed of high pressure air to provide a two step exhaust.

Abstract: Abstract of the Disclosure There is described an insulating connector for the wellhead of an electrode well used for heating a subsurface formation by electrical power dissipation in the formation.  The insulating connector has two iron base metal fittings (for example, steel flange halves) heat shrink fitted to a piece of ceramic pipe with a nonferrous second metal between the outer surface of the ceramic and the inner surface of the metal fittings.          The nonferrous metal (for example, copper) has a a lower yield that steel and a higher thermal expansion coefficient than the iron base metal and deforms, compen-sates and distributes the stresses caused in the shrink fitted members by the differences expansion between steel and cearmics.  Other features which improve the quality and control of various parameters affecting the heat shrink fit insulating connector include the amount of interference required per inch of outside diameter of the ceramic member, length of interference surface rela-tive to the outside diameter of the cermaic member, matching slightly tapered mating surfaces, bevelling the outside surface of the overlapping inner end of the metal members, and using a ceramic member with a flow passage larger than the flow passage through the metal members.

Abstract: ABSTRACT            The invention relates to a jet tip on the handle of an oral hygiene appliance. The jet of the jet tip has an opening in which a slidable core piece is displaceable, which core piece exposes only the outlet openings for a multiple stream in one of its two extreme positions in the jet and only a single outlet opening for a single stream in its other extreme position.     Advantageously, when the core piece moves from one extreme position to the other, contaminants or calcium deposits are automatically and mechanically removed from the outlet opening or outlet openings which is or are not exposed. The core piece can be positively mounted in the jet and be movable by pressure or tension force exerted by a spring and be thereby automatically locked into its two extreme positions.

Abstract: Patent Application For Electric Power Rod Abstract A device to feed an electric cable, from above, to power electric lawnmowers, snow-blowers, and other outdoor electric implements.  Thus avoiding the danger of cutting the cable as it is trailing on the grass or ground. Also  to easily and permanently store the electric cable under the protection of a roof overhang and a reel.          Specification When cutting grass with an electric lawnmower, for instance, it is common practice, at present, to have the power cable trailing along the ground behind the appliance. Thus making the work dangerous and inconvenient.  Dangerous in a way that the electric cable may be accidentally cut contributing to electric shocks and fires.     I have found that these disadvantages can be overcome by constructing an arrangement of rod and reel as presented in the overall view of fig. 1.     In fig. 1 the details of the invention consist of: A rod (1) constructed from an insulating material such as fiberglass or similar.  Being telescopic or rigid in construction, approx. 3-6m (10-20ft) long. The above said rod being attached to a bracket (2) which mounts under a roof overhang on the house wall or on the overhang itself.  (See fig. 1 and fig. 2). This bracket is constructed in such a way as to point the rod 0°-15°(adjustable) upwards when the rod is swung out at 90°angle from the house.  Yet swings under the roof overhang when parallel to the house wall where it remains for storage. (See fig. 2). At the base of the said rod and attached to it is a cable reel (3) containing sufficient length of electrical cable (4) to extend approx. 15-25m (50-75ft) beyond the end of the rod. This reel?should have a spring-action cable retractable mechanism.  Also incorporate a ratchet device which could be disabled at will. The electric cable coming from the reel should be passed through easy running blocks (5) and terminated with a three pin cap to allow to plug in the appliance used. A stop (6) should be provided on the cable as to limit its travel home into the reel, thus provide an end for convenient withdrawl of the cable for use when in storage position. The feed cable to the reel can be plugged in any convenient socket (electrical  outlet) or permanently wired.

Abstract: ABSTRACT OF THE DISCLOSURE      An earth boring bit having a cantilevered bearing  shaft and  a  compensator  system  to  equalize the pressure of the lubricant with the hydrostatic pressure of the drilling fluid surrounding the  bit.  A rigid face seal assembly, positioned between the cutter and  bearing  shaft  of  the  bit,  moves axially  in  response  to,  and  to  compensate  for, dynamic pressure changes in the lubricant adjacent  the  seal.   The positioning  of the seal groove and seal assembly in relation to the bearing surface is such that rigid face seal  movement is   decreased  relative  to axial  cutter  movement  during drilling to enhance seal life.  Preferably the ratio of rigid ring  movement  to axial cutter movement is substantially one half to one.

Abstract: ABSTRACT OF THE DISCLOSURE     In a front and rear wheel steering device control for a vehicle in which the steering angle ratio of the rear wheels relative to the front wheels is variable according to the vehicle speed, provision of a manual selection means for fixing the steering angle ratio to certain fixed values which may be either positive or negative can greatly improve the maneuverability of the vehicle in both high speed and low speed ranges.  However, inadvertent manual selection of the steering angle ratio is not desirable since it may cause a sudden change in the steering angle of the rear wheels.  Therefore, this invention provides means for preventing the manual selection of the steering angle ratio when it is not proper.  This means may be an active prohibition control of manual steering angle ratio selection means, an alarm to warn the driver or a vehicle speed control which limits the vehicle speed.  The situations in which the manual selection of the steering angle ratio is not proper may be determined from such factors as vehicle acceleration, transmission shift position, steering action and so on.
