Abstract: In a method and apparatus for securing a pre-cured tread to a tire during vulcanization to retread the tire, a sealing grid having annular rings disposed thereon to contact the sides of an envelope disposed about the tread and against the sides of the tire to cause a seal therebetween wherein said grids are easily joinable to effect such seal without the need of the tire being mounted on a rim or being inflated.
Abstract: A screen and a stationary screw propeller are arranged in round chambers between the carburetor and intake manifold of an internal combustion engine of an automobile, for example, to substantially increase the efficiency and gasoline mileage thereof.
Abstract: A multi-step glass forming machine having a plurality of mechanically actuated valves adapted to initiate the various steps in the operation of the machine is disclosed herein and includes an electronically controlled valve block assembly for mechanically actuating the aforestated valves. The valve block assembly includes a plurality of piston and cylinder arrangements, the pistons of which are pneumatically movable from a retracted position to an extended position for actuating respective ones of the valves. In this regard, the pistons are moved to their respective extended positions in response to the energization of an associated electrically actuated control valve and by a common pressurized air supply which is preferably independent of the glass forming machine.
Abstract: A support means having a vertically adjustable telescoping member with a first cantilevered member thereon for supporting a clasping means for engagement with the holding cord or other origin point of macrame to support same during the knotting process. A clasp on a second cantilevered member disposed beneath the first cantilevered member engages the holding cord to maintain the cord in a taut position as desired. Horizontal members extend from the vertical support to control the ends during the practice of macrame.
Abstract: A photon-counting detector array utilizes a one-dimensional multiple element anode array is in proximity focus to the last plate of the microchannel array for collecting the electrons generated therein. A specific embodiment has 64 anode elements. A detector system is provided with separate charge amplifiers, and level discriminators for each anode element. The discriminator outputs can be serially read out to a digital computer. Alternatively or additionally, the discriminator outputs are accumulated in counters, and display electronics are provided which can include digital-to-analog converters for forming a display representative of the counts accumulated in each counter, and the total count accumulated in all the counters.
Abstract: A multiple resonance microstrip antenna radiator which includes a plurality of stacked electrically conductive element surfaces disposed above an electrically conductive reference surface with each element surface dimensioned so as to resonate at a different radio frequency. The various element surfaces are spaced one from another and from the reference surface with a dielectric material and an rf feed is attached to at least one of the element surfaces. Non-resonant element surfaces provide inductive capacitive coupling of rf energy to/from a resonant element surface.
Abstract: A broadband antenna in the form of a multiple element interlaced dipole array is mounted on a thin elongated strip of dielectric material which is mechanically flexible, light weight and electrically small. Each dipole has a first tapered radiator section with an inductive loading section electrically connected to one end of the tapered radiator section. A capacitive end-loading section is connected to the inductive loading section. Second tapered radiator sections are joined to one another by a second inductive loading section. The inductive loading sections increase the effective electrical length of the first and second tapered radiators, respectively. A UHF gap filling conductor is connected to each of the dipoles to suppress grating lobes at the high-frequency end of the frequency spectrum received by the antenna.
Abstract: A punch for mating engagement with a ram for use in forming D&I can bodies. The punch has a plurality of lands disposed about the internal periphery thereof which results in the punch having significantly more mass at or near the nose thereof than it does at the opposing end. A plurality of lands disposed on the ram mate with respective lands within the punch to support and maintain the punch in a workable posture. The improved punch and ram assembly result in increased strength in the punch near the nose and increased strength in the ram at the area most removed from the nose of the punch and yet in engagement with the punch.
Abstract: Apparatus and method for inspecting the inside bottom surface of glassware for tramp glass by irradiating said surface with light having an angle of incidence of approximately 15 degrees and sensing any light transmitted through said surface as an indication of the presence of tramp glass.
Abstract: A dual slot antenna assembly is disclosed herein and generally includes a pair of concentrically positioned and radially spaced cylindrical conductors defining a pair of circumferential slots which are longitudinally spaced one-half wavelength apart at the anticipated operating frequency of the antenna device. An electrical signal feed assembly is connected with the conductors for exciting the slots so as to provide overlapping radiation patterns emanating in the same direction.

Abstract: A programmable automatic controller for operating machines having a plurality of components which operate in a timed or sequential relationship with one another. The controller includes a timing means for generating cycle clock pulses in synchronism with the operation of the machine, wherein the cycle clock pulses provide an instantaneous indication of the time elapsed in each cycle of operation of the machine. A COM/MOS running storage means stores the relative times during each cycle of machine operation when each of the plurality of machine components are to be enabled and/or inhibited. When the time elapsed in a cycle corresponds to a component actuating time stored in the running storage, an actuating signal is generated by a comparator. This signal is coupled to a machine component addressing arrangement which provides a component enable or inhibit command signal to the addressed component whose actuating time compared to the cycle time lapsed.
