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.
Abstract: An opaque vinyl envelope having facing polished inner surfaces and an open edge into which an intensifier screen and X-ray film are inserted. The other three edges are completely sealed except for a valve at one edge. Reinforcing strips are attached along the open edge. The three sealed edges of the envelope are heat sealed without pressure to eliminate an internal bead and minimize leakage along the bead when the open edge is closed and the envelope evacuated. An insert that has a relatively rough surface or is pourous assures full evacuation.
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.
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.
Abstract: A copolymer derived from a monomeric mixture comprising from 20 to 60 parts of acrylic or methacrylic acid, from 20 to 70 parts of a lower alkyl acrylate or methacrylate, and from 5 to 20 parts of a plasticizing monomer is at least partially neutralized by multivalent cations.
Abstract: Copolymers comprising acrylic or methacrylic acid and methyl methacrylate are neutralized by the addition of cyclic alkylene imines, preferably ethylene imine, to form a product which is capable of absorbing large amounts of material soluble in water, and slowly releasing those materials. The fundamental copolymer may be modified by the addition of cross-linking agents, chain terminators, plasticizers, etc., prior to treatment with the alkylene imine. The treated copolymers are particularly useful in the formation of contact lenses for the application of medicinals to the eye, and for other depot materials.
Abstract: A separable fastener is disclosed which has the form of a tape having a plurality of laterally adjacent uniformly corrugated strips. Adjoining strips are staggered relative to one another so that the ridges of one strip are laterally aligned with the depressions or spaces between the ridges of adjoining strips, with the adjoining strips being joined together at their cross-over points. A second tape of identical construction can be joined to the first tape by merely pressing the two tapes together in a face-to-face relationship. There is also disclosed apparatus and a method for manufacturing the separable fastener which includes means for passing a strip of thermoplastic material through mutually engaging rolling dies which create the corrugations.
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.

Abstract: A process for producing glass articles, particularly glass containers, comprises heating glass raw materials in a first location until the glass has been refined to approximately 60 to 95% of complete refining, cooling the molten batch and converting the semi-refined glass to a granular state, transporting the glass to a site for completion of refining and transforming of the glass into a finished glass product.
Abstract: A glass container, particularly a bottle, is wrapped in a plastic laminate which is held to the glass by an adhesive. The plastic laminate protects the surface of the bottle from abrasive forces which would diminish the strength of the glass, in combination with the adhesive substantially prevents scattering of the glass, should it be broken, and, because of its structure, provides for application of an attractive graphic design or label which is also protected from abrasion. The plastic laminate includes an inner laminate which is generally opaque, and an outer lamina which is transparent, the label or other graphic design being placed between the lamina.

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.
Abstract: An electronic thermostat for controlling the operation of a temperature changing device such as a heater or a cooling device to maintain the temperature of an object at a desired level. The thermostat comprises a device in heat exchanging relationship with the object for generating a temperature signal representative of the temperature of the object. A reference signal generator is operable to generate a reference signal representative of the desired temperature level. A comparator compares the reference and temperature signals and produces an operate signal to operate the temperature changing device when the reference and temperature signals are unequal.
Abstract: An ultrasonic alarm system comprising a transmitter having an oscillator which produces an ultrasonic carrier frequency signal. An audio signal generator produces a signal which modulates the carrier signal. The modulated signal is applied to a crystal through a tuned circuit. The transmitter is energized by operating a pushbutton which remains latched in operative position and which is unlatched only by the use of special devices. A plurality of receivers are provided and individual receivers are positioned at different locations throughout the premises to be protected. Each receiver includes a demodulator that demodulates the received signal and applies the same to a phase locked loop type phase detector which actuates an alarm when the demodulated signal is present. The alarm indicates the particular receiver that has been activated so that help may be dispatched immediately to the correct location.
Abstract: A game fostering the telling of a story based on iconographic stimuli. A set of objects and figurines are set up on a stimulus board. Each of these objects functions as an icon tending to invoke a significant primary emotion. Dice having different indicia on the faces thereof are thrown by the players. If a first indicia comes up, the players select one, two or three icons about which a story is told. The number of icons selected is a function of a numerical indicia on the die face. If a second indicia comes up, a card is selected which refers to an emotional category and calls for the player to tell a story about an icon on the board that fits the emotional category. Intermediate awards are given for each storytelling. Intermediate rewards during the game and more concrete rewards at the end of the game enhance the game feature and provide an incentive for storytelling and fantasizing.
