Abstract: DEVICE FOR IMPROVING FUEL EFFICIENCY AND METHOD OF USE THEREFOR A device for increasing the fuel efficiency in an internal combustion engine having a fuel supply conduit connecting a fuel supply and a carburetor, a hollow housing disposed in fluid communication with the fluid supply conduit between the fuel supply and the carburetor or firing chambers. A heat source, such as a heating element is mounted within the tubular member for heating the fuel flowing through the hollow housing. While flowing through the housing, the fuel is in intimate contact with metallized pellets of a metal, such as a noble metal deposited on a substrate. The pellets are disposed within the housing. In an alternate embodiment, hereof, two types of catalyst are disposed within the housing, one richer in metal content than the other. In practicing the present invention, the fuel passes through the housing and issues therefrom at a temperature less than 100.degree.C.

Title: Chlorination of copper, lead, zinc, iron, silver and  gold
Inventor: VON HAHN HARDWIN E A
IPC: C01G49/10

Abstract: Abstract of the Disclosure This invention relates to a process for making the chloride of a metal from the sulfide of said metal in the absence of air and for a metal selected from copper, iron, lead, zinc, silver and gold.  The process consists of three broad steps.  First, forming an intimate mixture of finely divided sulfides of the metals with finely divided chlorides, the latter being in an anhydrous state.  Second, heating the mixture to a temperature at which there is a rapid reaction converting the metal sulfides to chlorides and elemental sulfur in the state of a solid aggregate mixture.  Third, recovering the formed metal chlorides from the aggregate mixture by conventional means.         This invention is a process for forming a metal chloride of a metal or itscompound comprising forming a mixture of one or more metal chlorides being selected from the group consisting of ferric chloride, ferrous chloride, cupric chloride and cuprous chloride, and a metal or its compound, heating the mixture in the presence of a chlorine source to form the metal chloride and elemental sulfur and recovering the metal chloride from the mixture. Chlorine gas or sulfur chloride may be introduced into the mixture as an additional source of chlorine for reaction with the metal or its compound and for regeneration of a portion of the ferrous chloride or cuprous chloride into ferric chloride or cupric chloride.         The technical field is the forming of metal chlorides from metals or metalcompounds such as oxides,        ,carbonates and sulfates.  The chlorination may be for various purposes, such as the recovery of metals from their ores or the manufacture of the chlorides for subsequent use.         The present commercial methods for treating sulfide ores and concentrates involve roasting and smelting the sulfides in a series of operations which convert the sulfur to volatile sulfur dioxide.  The metal values are effectively recovered in these operations.  However, the very large volumes of sulfur dioxide produced are not always conveniently recovered, so that serious air pollution can result.  As a substitute hydrometallurgical processes are being extensively developed.  These processes convert the sulfide to solid elemental sulfur, with the metals being dissolved and recovered by various means.

Abstract: ABSTRACT     A liquid dispenser package is described which is adapted to dispense liquids without mess and which incorporates a measuring cup which is also the closure for the package. The package of the present invention includes a container having a dispensing orifice for storing the liquid product, a transition collar to be attached to the container finish surrounding its orifice and having an extended pouring spout and a transverse partition with drain to collect and return residual liquid to the container, and a measuring cup with an open mouth having threads on its exterior to attach the cup to the interior of the transition collar where it functions as the closure for the package. Because of the extended pouring spout, the residual liquid drain back feature, and the exterior threads on the measuring cup, virtually all mess normally associated with liquid product measuring and dispensing is obviated.

Abstract: ABSTRACT OF THE DISCLOSURE    An article and method for measuring the extent, location and rate of water vapor droplet impingements on various surfaces exposed to multi-dimensional and turbulent flow fields.  The article and method are employed in a non-icing atmospheric environment, and the results are used to prognosticate not only the areas where ice would accumulate if the water droplets were supercooled but also the concentration thereof.  The invention is accomplished by removably adhering a droplet impingement recorder (10) to a surface to be tested, such as an air-foil (20).  The droplet impingement recorder (10) incor-porates a water soluble gelatin coating (13) bonded to a substrate (11).  Droplets suspended in the flow field impact upon the recording surface (18) of the droplet impingement recorder (10).  The recording surface (18) is then micro-scopically analyzed to determine the size, location and concentration of droplet impingements which information assists one in prognosticating the most effective location for the installation of anti-icing or de-icing equipment.

Abstract: HIGH SPEED DRIVE CIRCUIT                          Abstract A driver circuit directly couples the clock signal to gate electrodes of pull-up devices to minimize the loading effect on the clock signal.  The pull-up devices pull up the output to substantially the positive power supply voltage. The clock signal is coupled to the gate electrodes of the pull-up devices by a transistor whose gate electrode is controlled by a control signal.  The control signal also triggers the pull down of the gate electrode of the pull-up devices when it is not desired to couple the clock signal to the gate electrode of the pull-up devices.

Abstract: C A N A D A TITLE:     STAPLE REMOVING APPARATUS INVENTOR: TREVOR W. OWEN                     ABSTRACT    An apparatus for removing staples from paper, card and like sheet-form material is disclosed.  The apparatus includes an anvil which deflects downwardly the leading end portion of a sheet inserted into the apparatus.  A staple in the incoming sheet abuts against a tongue which causes the tongue to pivot rearwardly.  The tongue is then moved towards the anvil to indent the paper adjacent the staple and orient the staple against the front face of the tongue.          Next, the tongue is returned to a vertical position and the staple is pressed upwardly into a relieved portion of a rotary knife.  The knife then slices off the top of the staple and removes the sliced off portion.  Remaining portions of the staple are stripped from the paper as it is withdrawn from the apparatus.

Abstract: 17.          ABSTRACT     A garment having a seamless crotch is described. The seamless crotch of the present invention may be used in conventional pants, such as dress pants and jeans, as well as in shorts.  In conventionally lengthed pants, an essentially curved diamond-shaped crotch piece with concave edges and long tapering sections which extend down the insides of the legs of the garment is sewn into the garment.  Forces generated by the assumption of a sitting position or by the raising of a leg of the wearer of the garment which would otherwise cause the garment to ride up the crotch are redirected in the area of the crotch.  In the crotch piece there is no center seam along the crotch and the seams of the crotch piece curved in directions becoming transverse through the crotch so that the garment therefore does not ride up the crotch.  In another embodiment a pair of shorts is described in which the crotch piece is truncated.

Abstract: ABSTRACT    A vinyl repair compound and two step vinyl repair method provide an exceptionally strong and long wearing repair.  The repair compound includes vinyl resins, a solvent, a plasticizer and silica filler, has a paste-like consistency and air dries.  The repair process entails the following:  trimming away the damaged material, placing backing material behind the damaged area if necessary, filling the repair area flush with the surface of the surrounding material with the repair compound and allowing it to air dry.  Due to shrinkage of the compound as it dries, a depression is formed which is then filled with a conventional heat curable plastisol vinyl repair compound.          If necessary, smooth or grained release paper is placed over the repair area, heat is applied to cure the plastisol compound and the repair is allowed to cool.
