Abstract: A unique supplemental carburetion device for internal combustion engines producing a primary source of fuel-air mixture for use at idle and low engine speeds resulting in decreased fuel consumption and exhaust emissions comprising a fuel reservoir chamber joined to a source of liquid fuel and determinate fluid communication with a fuel metering chamber. The metering chamber preferably is vented to ambient air pressure contains diaphragm valve means for controlling fluid flow into the metering chamber. Liquid fuel from the metering chamber flows into a nebulizing chamber and is nebulized by interaction with a stream of ambient air or blow-by gases. The fuel-air stream is passed into a venturi throat and vaporized and then passed into an expansion chamber where the stream is expanded under low static gas pressure to a mixture having a pre-determined fuel to air ratio. The mixture exits the device and is delivered into downstream portions of the carburetor throat.

Abstract: A child's teething aid article includes a teething portion constructed and arranged in the form of a helical coil spring from a cord-like length of resilient, nontoxic plastic material jacketing a flexible core member. The coil spring has an exterior diameter adapted to be received in the mouth of the child and presents a resilient mechanical force additional to the resilience of the material, against the compressive bite of the child applied normal to the coil spring axis. The teething portion is connected to a one or two part handle portion for manipulation of the article.

Abstract: Pressure sensitive adhesive film having special utility for maintaining medical devices on the human skin. The film comprises a laminated base layer on a surface of which a water based pressure sensitive adhesive is coated. The adhesive is formed of a mixture of a polyacrylic latex and an ester resin, together with a thickening agent.

Abstract: A large container, especially a silo, having a unitary, or one-piece material holding main part. A generally conically shaped unloading hopper is secured to the base of the main part by means of relatively thick, solid flange means which provides exceptional load-bearing properties at critical areas at the juncture of the main part to the unloading hopper. The container can be stacked in nested relation with other containers thereby making storage and shipment of the container more economical.

Abstract: Emulsifiable compositions of cosmetic emulsion oils, oxidized petrolatum and water, and stable emulsified water-in-oil personal care preparations produced therefrom by neutralizing the acidic functionality of the oxidized petrolatum with a polyvalent cationic water-soluble metal salt.

Abstract: Free standing apparatus adapted for use with a clip clinching tool capable, at high speed, of exerting a pulling force on a clip assembly whereby the clips comprising the assembly are sequentially severed and wrapped on elements of a workpiece, especially overlapping wire members employed in the manufacture of furniture, mattress innersprings, and the like, to firmly secure the wire members together. The apparatus includes a flexible track, provided with guides, along which the interconnected clips of the clip assembly are pull-fed into the clinching tool.

Abstract: A low cost sheet material, and a method of preparing same, which is useful as a substrate for casting sealants and adhesives. The substrate comprises a highly calendered, smooth grade kraft paper having a coating of an elastomer modified polyvinyl chloride on each of the major surfaces thereof. Either one, or both, of the polyvinyl coatings are provided with a film of a release agent thereon.

Abstract: A clutch interlocking mechanism for use in a pushbutton tuner wherein a drive gear provided on a clutch mechanism is meshed with a rack of a memory slide, a support bracket, on which the clutch mechanism is mounted, is supported, at one side thereof, by a frame on a chassis through a fulcrum pin and, at the opposite side thereof, provided with a tension spring to assure positive engagement of the drive gear with the rack. The clutch interlocking mechanism further comprises a resilient member provided for the fulcrum pin to eliminate looseness at the portion of the fulcrum pin.

Abstract: A desk pad comprising a one-piece, molded body portion for supporting a writing pad divided into a plurality of smaller writing pads, and having magnetized areas for attaching notes and memoranda in an attention-getting position on the desk pad.

Abstract: Condensing instruments are used for packing and condensing in connection with placement of dental composite resin restorative materials. These instruments are manufactured in metal or plastic material. Some composite resins however, contain hard particles and require a relatively large condensing pressure which causes abrasion of superficial fragments of prior art metal instruments. These fragments are confined in the restorative material and causes discoloration, often after oxidation. Plastic instruments quickly loose their surface finish, which may render it impossible to perform an adequate condensation. In order to provide an instrument which does not cause discoloration and which guarantees a durable function, at least one functional member (4 and/or 5) of the instrument consists of a metal alloy having a coating (6 and/or 7) of ceramic material which provides the working surface (8 and/or 9) of the functional member.

Abstract: A stable aqueous dispersion of a room temperature curing polymer effective for forming films resistant to water and organic solvents, said polymer being a water-dispersible vinyl addition polymer containing a sufficient proportion of pendant N-methylolhydrazide groups to cause the polymer to cure in situ on a substrate when said dispersion is applied to the substrate and dried at ambient temperature. The polymer preferably sufficient pendant carboxylic salt groups to render the polymer water-dispersible or water soluble.

Abstract: A lubricant composition having special utility as a lubricant in constant velocity universal joints of the type used in front wheel drive vehicles. The composition comprises a low sulfur lubricating oil base grease and an additive package comprising a mixture of an oil soluble, sulfur-free organic compound and an oil insoluble sulfur-free inorganic compound.

Abstract: An improved clip assembly in the form of a row of aligned U-shaped clips. The clips are maintained in aligned relation to each other by resilient interconnecting means such as small diameter flexible strong metal wires which advantageously are intimately secured to the crown portions of the clips by a metal-to-metal bond. The assembly can be wound, in the manner of spool of thread or wire, into a tight, self-sustaining, compact roll comprising thousands of clips. The invention also involves a method of producing said improved clip assembly and a method in which said improved clip assembly is utilized to wrap the U-shaped clips on overlying wire members to produce bed spring, furniture and the like.

Abstract: A gelatin dessert product capable of providing a clearly demarcated two-layered, two-colored dessert in a single step.

Abstract: A method for the preparation of isethionic acid by treating an alkali metal isethionate with hydrochloric acid to form isethionic acid and a chloride salt. The chloride salt is removed so as to provide at least a 50% by weight aqueous solution of the isethionic acid after removal of excess hydrochloric acid, which solution may be further reacted with a polyvalent metal oxide, hydroxide or amine to form the corresponding heavy metal isethionate. Zinc isethionate, for instance, is useful as a catalyst for making acyl isethionates used in making soap bars.

Abstract: A switching timer device includes a manual switch having "on", "off" and "timer" positions. When the switch is set in the "on" position a load is supplied continuous power from a source. When the switch is set in the "timer" position, a load-powering power switch is closed for a predetermined length of time determined by a timer that is automatically reset when the manual switch is so actuated, and after elapse of the predetermined time the power switch is opened to de-energize the load. The timer is configured as a direct replacement for existing wall-mounted switch units without requiring access to the low side of the line, and consumes no internal power when in the normal "on" position.
