  • Patent number: 4521191
    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.

  • Patent number: 4508220
    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.

  • Patent number: 4499028
    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.

  • Patent number: 4494012
    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.

  • Patent number: 4476205
    Abstract: A cadmium electrode for a rechargeable alkaline cell comprises a rigid substrate having particle-receiving recesses therein into and upon which are pressed a particulate mix of binder coated cadmium oxide particles and cadmium particles which constitute an active precharge anti-fading constituent of the mix. The binder coating may be a substantially insulating material, in which case the cadmium particles in various places are pressed into the substrate so that they penetrate through the binder coating to make direct contact with the cadmium oxide particles. The binder is most advantageously a curable butadiene polymer binder coating on the cadmium oxide particles preferably formed by heating an initial slurry of an emulsion of the binder and cadmium oxide particles to vaporize the liquid carrier and at least partially cure the binder material.

  • Patent number: 4470531
    Abstract: An improved nailing machine including a reciprocatable plunger for sequentially severing and driving nails from a nailing strip, and a reciprocatable piston for advancing and retracting the plunger. The machine includes a unique reciprocatable control valve actuating and nail guide means which serves both to set a control trigger for activating the reciprocatable plunger, and to properly align a nail with a workpiece as the nail is driven into the workpiece, while at the same time maintaining the nailing strip in a fixed position to prevent contact between the driven nail and the next nail to be severed from the nailing strip. The machine further includes a magazine having retractable nailing strip advancing means which positively moves a nailing strip along the runway of the magazine, and which, in its retracted position, enables a nailing strip to be easily and readily inserted into or removed from the magazine of the machine.
