  • Patent number: RE28758
    Abstract: Fundamentally, the invention pertains to a method and apparatus to be used in binding books. The apparatus may be constructed relatively small and portable, and may be used in offices and print shops where binding machines of the prior art are not practical due to size, expense, and complexity of operation and their inadaptability to small lot binding activity. The relatively small size and portability of the apparatus is made possible by a method of inserting into the book cover, a hot melt adhesive in cool hard form and melting the adhesive material by applying heat externally to the book cover to be bound. The apparatus therefore, comprises a number of devices in combination including a heating rack to heat the binding edge of the book, a cooling rack to cool the edge of the book cover, a mechanism that folds the book cover, and a device that adjusts the folding mechanism so as to fold the book cover in such a way as to accommodate the thickness of the collated pages to be bound.

  • Patent number: RE28759
    Abstract: A system for distributing successively formed groups of glass gobs from a feeder bowl to the several individual sections of a Hartford I.S. type glassware forming machine includes a single scoop for each gob in the group, and mechanism for rotating the scoops between successive positions wherein each is aligned with a chute associated with a particular mold cavity in each machine section. A "double-gob" installation is described and the two scoops have associated annular spur gears which are driven in unison by a reciprocable rack gear through a predetermined schedule of angular displacements to successively align the two scoops with several sets of paired chutes according to a particular order and to then repeat this schedule. A cam follower connected to the rack gear causes programmed movement thereof in response to rotation of a cam having lobes of predetermined height to produce the predetermined schedule of angular displacements of the scoops.

  • Patent number: 3947929
    Abstract: A method is disclosed of securing a fabric web to a printing blanket. A plurality of needles are inserted into the printing blanket at the web-supporting side thereof, so that tips of the needles project from that side. The needles are then anchored in the printing blanket and the web is placed onto the printing blanket so that the tips of the needles enter into the fabric web and retain the same against displacement relative to the printing blanket. A needle for this purpose is also disclosed.

  • Patent number: 3947930
    Abstract: A fastening device for securing articles together, the device including releasably connected male and female components. The male component comprises a pin and the female component comprises a retaining insert positioned in a housing for releasably clamping the pin. When joined, the pin can not be separated from the retainer except by a special tool. The insert is of magnetic material, and an actuating tool including an electromagnet is employed to actuate the insert to permit removal of the pin. The housed insert is attached to a tag, with the tag being attached to the article which is to be sold. The tag houses an electrical circuit which activates an alarm if the tag is not properly removed at the checkout point by means of the special tool.

  • Patent number: 3947931
    Abstract: A sliding clasp fastener including interlocking elements of a continued meander structure which are disposed astride a longitudinal tape edge at their leg and connecting portions. The leg and connecting portions are deformed to provide flattened, enlarged undersurfaces adapted to be held in intimate contact with the tape. The connecting portions are also deformed to produce recesses for receiving therein side flanges of a slider.

  • Patent number: 3947933
    Abstract: The center-to-center spacings of a photoresist pattern for an array of holes applied to a thin metal sheet are increased by uniformly stretching the thin metal sheet in all directions along the plane of the sheet. The uniform stretching is provided by securely clamping the periphery of the sheet and applying an annular force against the face of the sheet, within the periphery of the sheet and around the photoresist pattern. The technique used in the construction of ion thruster grid units wherein the outer or downstream grid is subjected to uniform stretching prior to convex molding. The technique provides alignment of the holes of grid pairs so as to direct the ion beamlets in a direction parallel to the axis of the grid unit and thereby provide optimization of the available thrust.

  • Patent number: 3947934
    Abstract: A microelectronic LC circuit capable of being tuned to a desired center resonant frequency, comprising a trimmable capacitor, a principal fixed inductor and a printed trimmable inductor having an inductance which is small compared to that of the principal inductor. The printed inductor is one which is capable of having its inductance raised by trimming. In some cases, the fixed inductor can be omitted.

  • Patent number: 3947935
    Abstract: A lea making mechanism of a reeling machine has a cylinder movable up and down and having a tapered face and a rod secured to a piston of the cylinder. The piston has a pointed head adapted to be received through the hank threads. The mechanism also comprises a set of inwardly curved pipes through which the lea thread is led.During the operation of the mechanism, the cylinder only is forced downward and the tapered face pushes open the set of pipes and then the cylinder is raised to pull up the lea thread extending through the hank threads.

  • Patent number: 3947937
    Abstract: In a cutting element for cutting metals and having adjacent surfaces which meet to form a cutting edge, with a chip-controlling groove being formed in one of the surfaces, the groove being composed of a plurality of depressions disposed parallel to one another, spaced apart in the direction of the groove width, and extending along substantially the entire cutting edge, the ability of the groove to effectively deflect chips having a wide range of thicknesses, or cross sections, is improved by forming the groove to have more than two such depressions, with the depressions arranged to form a ridge between each two adjacent depressions, the ridges being located such that, in the direction extending away from the cutting edge, each succeeding ridge is at a higher elevation than the preceding ridges.
