Abstract: ABSTRACT OF THE DISCLOSURE          A hydrous gel consisting essentially of a heat-moldable w/o emulsion comprising about 15 to about 95% by weight of a continuous phase of an A-B-A type teleblock copolymeric elastomer and an oil component and about 85 to about 5% by weight of an emulsified dispersed water phase.  The hydrous gel is prepared by dissolving the teleblock copolymeric elastomer in an excess of the oil component by heating, adding an emulsifier and water to the solution to disperse the water therein and to form the w/o emulsion, and then cooling the resulting emulsion to room temperature.  The hydrous gel finds a wide range of utility, for example, as an insulator, especially to maintain low or high temperature environments, as a fireproofing material, as a heat absorbent, and as a hospital mat.

Abstract: ABSTRACT OF THE DISCLOSURE          A method and apparatus for measuring a mechanical characteristic of a band subjected to tension.  A disturbance is produced, for example by a hammer, transversely of the band and there is measured the time that the disturbance takes to travel through a predetermined distance along the band.  This measurement is related to the value of the tensile stress in the band.  In this way planarity defects in the band can be detected by comparison of the times the disturbance takes to travel in different regions of the band.

Abstract: GUIDED BEAM FLAT DISPLAY DEVICE                            Abstract An evacuated envelope has a rectangular display section and a gun section at one edge of the display section.          The display section includes front and back walls which are generally rectangular, in closely-spaced  parallel relation, and a plurality of spaced  parallel support walls between the front and back walls forming a plurality of parallel channels.          The gun section extends across one end of the channels and in-cludes therein a gun structure which will direct electrons into the channels.  In each of the channels is a beam guide which confines the electrons in a beam and guides the beam along the length of the channel.  The beam guide also includes apertures through which the electron beam may be selectively deflected out of the guide at selective points along the guide so that the beam will impringe upon a phosphor screen along the inner surface of the front wall.  In each of the channels is a scanning deflector which deflects the path of the beam as it passes from the guide to the phosphor screen so that each of the beams will scan a portion of the phosphor screen.

Abstract: ABSTRACT     A method of filling and pressurizing container-dispen-sers includes loading a gas-adsorbent solid and an adsorbable gas into a chamber separate from a chamber containing the pro-duct to be dispensed.  The solid can be loaded prior to charg-ing of the product through a first orifice, and thereafter the source chamber is charged with gas through a second orifice.          Alternatively, the source chamber can be filled in whole or in part while remote from the product chamber and thereafter in-serted into the product chamber.     The pressurized container-dispenser has a separate pressure source chamber containing a gas-adsorbent solid and an adsorbable gas and having means to transmit source chamber pressure to a product chamber for dispensing of a product therefrom.  Transmission means may include a movable wall sep-arating the product and source chambers, a check valve, a constant pressure valve, and a membrane of the type allowing passage of gas but resisting passage of non-gaseous fluid.          The source chamber can be defined by an enclosure of substan-tially fixed volume secured adjacent the product chamber. Al-ternatively, the source chamber can be defined by an unsup-ported enclosure free within the product chamber.

Abstract: METHOD AND DEVICE IN AN INSTALLATION FOR TREATING AIR-BORN WEB MATERIAL PASSING THROUGH THE INSTALLATION   Ingemar Karlsson - V?xj?, Sweden Abstract Web material is carried on air to advance the material in a fixed stable floating position through one or more decks of a treating plant, preferably a drier.  The air is supplied through pairs of apertures arranged in the upper surface of blow-boxes distributed in the conveying path of the material which apertures eject the air in pairs of stream facing away from each other.  To reduce deflection of the material between said pair of apertures the space between said apertures is supplied separately with a great volume of secondary air of the same static pressure as that prevailing on the upper surface of the material, which secondary air is taken along by ejector effect by the primary air streams ejected from the apertures of the blow-boxes.

Abstract: SOLID STATE PULSING APPARATUS FOR PULSING SELECTED LINE RELAY TERMINALS                      Abstract of the Disclosure A solid state pulsing circuit and an adapter connector for pulsing the counting and register advance terminals of the L-(line) relay of an originating register in accordance with the digit nature of received DTMF signals is disclosed. The pulsing circuit includes a pair of solid state switches adapted to be alternatively actuated and the adapter connector connects the pulsing circuit to the counting and register advance terminals of the line relay without affecting the normal operation of the relay. Complementary MAKE and BREAK signals derived from the serial pulse output of a DTMF receiver operate the solid state pulsing circuit such that the pulsing circuit alternately pulses (opens and grouds) the counting and register advance terminals of the line relay in accordance with the production of pulses by the DTMF receiver. Other relay terminals (i.e., the terminals controlling the slow release supervisory relay adapted to detect the ON HOOK state of a subscriber's telephone) are not pulsed, whereby annoying line clicks are avoided.

High impedance current sources having voltage follower operational amplifiers are integrated into the hybrid for reducing hybrid bridge loading on the bidirectional 2-wire path while providing adjustable levels of transmission in all directions.  One of the high impedance sources is responsive to signals received from the receive amplifier via a bridge resistor for generating output currents to produce desired levels of the received signal on the 2-wire bidirectional path.  A second one of the sources is responsive to signals received from the receive amplifier via another bridge resistor for generating currents within the bridge which are opposite to those of the first source and which cancel the receive signal at the input of the transmit amplifier to preclude undesired circulation of that signal back to the operator console.                             - i -

Abstract: ABSTRACT:         A motor control circuit for an a.c. motor which is energized via power switches by a direct voltage obbained from an alternating voltage mains via rectifiers and a smoothing capacitor. A frequency reference signal is applied to a circuit which controls the power switches via a first amplirier with output signal limitation in series with an integrator, whose output provides feedback to the input of the first amplifier. A negative current-feedback loop with a motor current detector, whose output signal is com-pared with the reference signal in a comparator, acts at a point between the amplifier and the integrator in order to close the negative feedback loop when the motor current exceeds a predetermined value. A negative voltage-feedback loop with a detector for the direct voltage obtained from the a.c. malns, the output signal of said detector being compared with a reference signal, also acts at the point between the amplifier and integrator in order to close said negative voltage-feedback loop when said direct vol-tage exceeds a predetermined value.
