  • Patent number: 3970506
    Abstract: The following specification describes apparatus for successively applying magnetic patches on a tape to successive passbooks. Each passbook is moved in sequence to engage a switch and is then stopped. The switch operates a solenoid, which engages a roller with the passbook and disengages the stop. Thereafter, a metered pulse is applied to the motor of a rotary drive to move the passbook and tape through the same distance and one patch is separated from the tape and applied to the passbook by the solenoid engaged roller. As the tape moves under control of the metered pulse, a succeeding patch on the tape is sensed by a photocell to maintain the motor and rotary drive operated. The drive continues to advance the tape and when the succeeding patch is no longer sensed by the photocell, it provides a signal to deenergize the motor and stop the tape. The succeeding patch is thus accurately positioned for application to the next passbook operating the switch.

  • Patent number: 3969169
    Abstract: Interposed between the conductor and the helical or longitudinal wrapping of paper insulation is a layer of selfsetting, heat sealable emulsion having adhesive properties and which is inert, water soluble and free of metal. The emulsion is absorbed by the innermost lay of the paper and causes it to adhere to the next outer paper lay, while the outer portion of the paper which is not exposed to the saturated portion remains loosely formed around the conductor. Upon drying of the paper insulation, the solid portion of the emulsion remains as a film on the periphery of the conductor and the innermost surface of the paper.

  • Patent number: 3967997
    Abstract: Tandem operations for manufacturing coaxial cable units include new and unobvious methods and apparatus for laminating an outer conductor, for drawing an inner conductor, for applying plastic discs to the inner conductor and for corrugating the outer conductor. Laminating the outer conductor is accomplished by passing a copper, copolymer adhesive, steel sandwich through three pairs of heated rolls. The heated laminate is passed over a roller designed to impart a three-dimensional curvature to the laminate. Then, the laminate is advanced in the manufacturing atmosphere and over another roller to remove the three dimensional curvature while the heat is removed. This produces a laminate which is essentially stress-free although composed of dissimilar materials. The inner conductor is drawn to a final diameter by an ultrasonically vibrating drawing die within a liquid medium which acts as a lubricant and as a cleaner to form a clean, smooth inner conductor.

  • Patent number: 3964945
    Abstract: A corrugated plastic article comprising at least two corrugated plastic films each of polyethylene terephthalate held in contact with each other and capable of substantially maintaining its shape under extreme use conditions.Such corrugated plastic article when heated for 5 minutes at 150.degree.C. has a percent (%) fallout (i.e., the original peak-to-peak height of the corrugations minus the retained peak-to-peak height thereof after heating divided by the original peak-to-peak height) of less than 35%.In an electrical cable having a conductor core, this corrugated plastic article provides an improved protective member for the core, having good dielectric strength and mechanical strength, electrical stability, low moisture sensitivity and other properties, wherein the corrugations, strength and shape-retention capabilities of the article provide improved cushioning, insulation and other protection for the core.

  • Patent number: 3951712
    Abstract: In the disclosed method of applying electrical insulation, a housing with a porous wall is placed around a conductor in spaced relationship thereto, and a slurry is pumped into the space between the housing and the conductor. This slurry comprises a liquid and particles suspended in the liquid having good electrical insulating properties. The liquid component is allowed to discharge from the housing via its pores, but the solid particles are filtered out within the housing so as to build up from the internal surface of the housing a deposit of the particles. This pumping and filtering action is continued until the space between the housing and the conductor is substantially filled with the deposit.

  • Patent number: 3938931
    Abstract: A method and apparatus for insulating a plurality of electrically conductive elements and to produce electrical cable where the method includes heating the unformed insulative material and conductive elements, applying pressure and simultaneously removing heat with a pair of rollers at a relatively low temperature and applying pressure and heat to preselected regions only of the insulative material. The method and apparatus further allow preselected portions of the cable to be unbonded so as to facilitate access to the conductive elements by simply interrupting the application of pressure to the preselected portions. The heat, press and cool and press and bond method may also be accomplished in a step and repeat process using presses to insulative flexible circuits. The above method and apparatus provide more reliable bonding at an accelerated rate of production.
