  • Patent number: 4570797
    Abstract: A portable carrier for adhesive tape, comprising a plurality of side-by-side support strips each having an adhesive tape strip releasably secured thereto. The support strips are detachably secured to a base portion, and several of these base portions may be arranged in juxtaposed relationship to one another so that the carrier will be of a convenient, compact substantially flat configuration. A further aspect of the invention is a method for the manufacture of such a carrier.

  • Patent number: 4569349
    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.

  • 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: 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: 4479596
    Abstract: A carrying case for portable electronic paging devices has a partitioned receptacle assembly with a first receptacle to receive the paging device and a second receptacle to positively receive and engage the device's mounting clip. A releasable strap allows the receptacle assembly to be tripped or pivoted away from the wearer while being worn by the wearer to enable the paging device's controls or indicators to be generated or read.

  • Patent number: 4379572
    Abstract: An air suspension system adaptable to various types and sizes of vehicles, including automobiles, trucks, vans and the like, to improve their riding characteristics and stability, including a carrier arm assembly pivotally mounted at one end to the frame of the vehicle and connected near its opposite end to the vehicle axle. The system has an air spring disposed between the first pivotal end of the carrier arm assembly and the axle and interposted between the carrier arm assembly and the vehicle frame so that the air spring supports at least the major portion of the vehicle load and responds to any deflection of the wheels mounted at the opposite ends of the axle. The air suspension system is adjustable relative to the axle and the frame to permit alignment of the axle. The system also includes a means of supplying air to the air spring through independent reservoirs and releases air from the air spring at desired rates to control the compressibility of the spring and the riding characteristics of the system.
