  • Patent number: 3961585
    Abstract: A net of the type having a plurality of intersecting straps forming a lattice structure which is adapted to encompass a load to maintain the load on a support or a pallet. The net comprises a top section having diagonally extending interconnecting straps and integral front, rear, and side sections. The sections are adapted to be connected to the support to maintain a load within the net in place. The front and rear sections are connected to the side sections through the diagonally extending straps of the top section so that a portion of the forces applied to the front or rear section due to acceleration or deceleration of the load are transmitted to the side sections thereby to distribute the forces generated by the load.Other features include means for encircling the load at an intermediate point independently of the sections thereby maintaining smaller loads centrally positioned on the support. Additionally, bracing straps are provided to eliminate undesirable movement of the side sections.

  • Patent number: 3959704
    Abstract: A three-phase A.C. motor is connected to a three-phase A.C. supply through three sets of oppositely poled SCR's, one set being connected in each phase. Triggering pulses are supplied to the gates of the SCR's by triggering circuits. During starting of the motor, triggering circuits control the phases of the triggering pulses in relation to the phases of the supply in accordance with a ramp signal developed by the solid state starter circuit. The ramp signal increases the conduction angles of the SCR's until the motor has accelerated to running speed at which time maximum conduction of the SCR's is attained. The solid state starter circuit features closed loop control in generating the ramp. An overload protector circuit establishes different overload levels during starting and running of the motor and operates to terminate the application of triggering pulses to the SCR's if a motor overload condition is sensed during either starting or running.

  • Patent number: 3959066
    Abstract: Three-ply web material is rolled approximately 360.degree. into the form of a cylinder within a preform cavity. A feed roller at the opening rotates continuously and a spring loaded pressure plate has an edge at the opening which forces the web material against the feed roller. After the trailing edge of the segment of web material has passed the edge of the pressure plate, contact between feed roller and web material is lost and the circumferential position of the seam of the preform is thus precisely located. There is a slight overlap between the ends of the material at the same. The preform is longitudinally transferred into a non-conducting cylindrical forming cavity where heat and pressure are applied to fuse the overlap and form the seam. Heat is applied by induction heating through the walls of the forming cavity to the aluminum ply at only the overlap area. Pressure is applied by an expandable balloon mandrel inside the preform.

  • Patent number: 3955311
    Abstract: A push button in the upper side of the torso of a toy figure is hand operated. By pushing the button this motion is transmitted to a lever which is rotated upwardly. The upward motion of the lever is translated into a rotary motion of a ball joint which is connected to an upper arm of the toy figure. By movement of the push button the arm of the toy figure is thus moved from a preselected position into an upward position. A connection between the upper and lower arm portions permits the lower arm portion to continue movement after the upper arm portion has stopped thereby imparting a life-like movement to the figure.

  • Patent number: 3944928
    Abstract: A communication system comprising a transmitter for radiating a carrier frequency signal, which may be modulated, to a data station. The station includes a rectifier for rectifying the received carrier signal to provide energy to the station elements. A data source at the station produces a data signal representative of the information to be transmitted. A harmonic generator produces harmonics of the carrier signal and the harmonic signal is modulated with the data or information signal. An antenna radiates the modulated harmonic signal to a receiver which demodulates the received signal to extract the information therefrom. Thus, a completely self-contained and economic system is provided, since the carrier signal per se supplies the energy to operate the data station.Additionally, the communication system may include a carrier signal having an address encoded therein and the station may comprise an address decoder so that only a selected addressed station will transmit the desired data at any one time.
