Abstract: A stitch shortening and tacking assembly for use in a sewing machine is provided. The shortening and tacking assembly is particularly suited for use with a sewing machine wherein a fabric is advanced between a presser foot and a platen disposed in a first feeding position by a reciprocating feeder that is synchronized with respect to a rib and sewing needle. The sewing needle is synchronized with respect to the feeder and rib to stitch the fabric after the web has been advanced by the feeder. The platen is adapted to be displaced from the feed position to a stitch shortening position whereby the web is advanced through a shorter interval between sewing operations to thereby shorten the length of each stitch effected thereby. The platen is further adapted to be displaced from the stitch shortening position to a stitch tacking position whereby a portion of the platen is biased against the presser foot to thereby prevent the fabric from being advanced between sewing operations.
Abstract: A method and apparatus is provided for controlling the period or pulse width of pulses applied to exothermic printing elements of a thermal printer to effect printing.

Abstract: In a printing device, printing type rings are mounted on a rotatable, grooved shaft. Each ring has associated therewith a pawl and a selecting mechanism for engaging the pawl with a selected groove on the printing type ring whereby a selected character on the ring may be brought to an inking position and then to a printing position. Retraction of the pawl by said printing mechanism disengages the pawl and allows the ring to reach a rest or stand-by position.By the use of the retractable pawl a printing device is provided in which only those rings which are about to be used for printing are rotated, and the load on the inking mechanism is greatly decreased. The printing device may therefore be decreased in size and in energy consumption and the wear on the various members of said device is greatly decreased.
Abstract: A web-feeding mechanism for a compact printer which can feed at least one web of paper at selectively variable feeding rates is provided. A pair of rotatably driven web feeding rollers is positioned on a first side of the web of paper to be fed, and cooperates with a pair of selectively displaceable idler rollers correspondingly positioned on the other side of the web. The respective feeding rollers are each capable of being driven at a different rotary speed. The respective idler rollers are selectively displaceable between a first position out of engagement with its associated web feeding roller, at which time web feeding by the feeding roller corresponding thereto is prevented, and a second position in engagement with the paper web and the web feeding roller corresponding thereto for feeding the web therebetween at the feeding rate of the feeding roller.
Abstract: A ceramic capacitor operatively connected to a piezoelectric oscillator for compensating for the temperature dependence of the oscillator frequency is provided for thereby optimizing the accuracy of an electronic timepiece.
Abstract: A thermoplastic control complex for releasably securably bonding and debonding distinct elements together is provided. An elongated exothermic electrical conductor having a predetermined resistivity for each lengthwise unit thereof is provided with a thermoplastic resin selectively positioned along the length thereof. The complex is disposable between two distinct elements so that the thermoplastic resin is selectively transformed from a non-sticky substantially solid state to a substantially liquid state in response to a current being flowed through the exothermic conductor, whereby the thermoplastic resin, in the liquid state, effects wetting of the distinct elements for effecting subsequent releasable securable bonding of the elements together.
Abstract: A sea terminal having compartments for storage of fluids and adapted for the transfer of the fluids between the compartments and a ship. The sea terminal is constructed to eliminate the need for swivel hose connections as the ship swings in relation to the terminal. In another embodiment, the sea terminal may be sufficiently large to include drilling apparatus thereby providing a self-contained terminal which can drill into a sea bed, pump sub-sea oil into the compartments in the terminal and transfer the oil to a cargo ship. Alternatively, the sea terminal may be transported to a discharge point for discharging the oil.
Abstract: Electronic components having parallel leads are mounted equidistantly by means of said leads on tape. The tape is wound in a spiral and packaged in a box prepared from a box blank. The box has a hinged opening in the side thereof through which the tape and the electronic components mounted thereon can be fed either manually or automatically without opening the package itself.

Abstract: An artificial fingernail package has a transparent portion through which one or more artificial fingernails are visible enabling a possible purchaser to select fingernails by placing her finger beneath the transparent portion and looking through the transparent portion. The artificial fingernails may be loose or secured to a retaining frame.
Abstract: An electronic timepiece wherein the timekeeping circuitry utilizes semiconductor-insulating substrate integrated circuitry for effecting high frequency operation is provided. The timepiece includes an oscillator circuit adapted to produce a high frequency time standard signal and is comprised of at least one inverter stage coupled to a high frequency time standard. A divider circuit formed of a plurality of series-connected divider stages produces a low frequency timekeeping signal in response to the high frequency time standard signal being applied thereto. A display is provided for displaying time in response to the timekeeping signal being applied thereto. The oscillator circuit, divider circuit and display include integrated circuit elements and at least the inverter stage of the oscillator circuit includes at least one complementary coupled pair of P-channel and N-channel conductive field-effect transistors having a semiconductor-insulating substrate construction.
Abstract: A device for displaying and storing articles includes a wall structure which defines at least one chamber which is open at one end and which is adapted to receive in its interior a plurality of articles arranged one behind the other with one of the articles situated nearer to the open end of the chamber than the other articles. A pusher engages in the chamber that one of the articles which is most distant from the open end of the chamber, and a spring structure cooperates with the pusher to urge the latter toward the open end of the chamber so that the pusher tends to advance the articles out of the chamber through the open end thereof. A retainer structure is situated at the open end of the chamber for retaining the articles therein in such a way that the particular article which is nearest to the open end of the chamber can be manually removed therefrom, whereupon all of the articles are advanced by the pusher until the next article occupies the space previously occupied by the withdrawn article.
Abstract: An improved device for the introduction of fluids into blood vessels, and, particularly, into veins, includes a cannula-containing portion fitted with a valve which is normally closed.
