Abstract: Abstract of the Disclosure To provide a hermetic seal for flexible receptacles such as plastic bags, pouches, or casings, the outside of the mouth of the receptacle is coated with a cold flowing resin so that when the receptacle is filled and its mouth gathered under pressure the resin will cold flow and fill the voids in the gathered folds.  Preferably, the end of the gathered mouth is trimmed and then high pressure is applied to cause the resin to exude from the trimmed end.  Next, a forming plunger is used to press the exudate into a smooth surface whereby a fused cap of resin is formed hermetically closing the bag's mouth.  As an alternative, a clip or band can be placed around the gathered end under sufficient pressure to cause cold flow of the resin thereby sealing the voids.

Abstract: ABSTRACT:         An automotive trim strip laminate formed of a strip of polyester material bearing a layer of metallic material covered by a thin polyvinyl chloride layer bonded to a supporting substrate of a flexible plasticized poly-vinyl chloride material is made so that the laminate can be thermally bonded to a support material along a curved path without any irregularity, which is recognized as caused by compression wrinkling from thermal stress along radially inner regions of the curved path.   This is prevented by selecting the polyester strip and the thin polyvinyl chloride layer with physical characteristics and dimensions to provide the  metalized polyester strip with sufficient dimensional stability relative to the polyvinyl chloride substrate to prevent any such compression wrinkling, and one preferred way is to make the thin polyvinyl chloride layer substantially  unplasticized and formed of a smooth, medium impact material.

Abstract: ABSTRACT      A controlled feeder block for use as a telecommunications interface provides a plurality of slidable switching assemblies, each of which is selectively used to connect an in-feeder wire to either an out-feeder or a wire receiving terminal.  The feeder block provides an uncomplicated and compact interface system without a large number of detachable, non-reusable parts and which may be used without specialized tabs.  An insulative feeder block is used having contact elements mounted therein for selective connection to two wires.  A terminal post is adapted to slide between two positions within said insulative block.  The terminal post carries in electrical isolation a terminal conductor electrically connected to a wire receiving terminal and a bridging conductor.  This bridging conductor makes electrical contact with both contact elements when the terminal post is in one position.  When the terminal post is in the other position, the terminal conductor makes electrical contact with one of the contact elements.

Abstract: CULTIVATOR TOOL SHANK ASSEMBLY                 Abstract of the Disclosure This invention relates to a cultivating shank assembly in which a mounting frame is comprised of a mounting frame portion and a tool shank support portion pivoted thereon.  The mounting frame portion and the tool support portion are formed of plates which are held together by   suitable transversely extending plates which support the mounting frame on a cultivating tool bar and mount the tool shank respectively.  A compression spring for the mounting assembly is connected between the tool shank portion and the mounting frame portion of the mounting frame and is guided between inner and outer cylindrical spring retainers which are pivoted respect-ively on the tool shank support portion and the mounting frame portion to prevent the compression spring from buckling and to guide the same such that the compressive force will always be applied along the extent of the spring. Suitable apertures in the mounting frame portion provide a limit stop to define the pitch adjustment of the tool shank and provide preload adjustment for the compression spring.

Abstract: RCA 71,840 Abstract An automatic fine tuning (AFT) circuit is provided which generates an AFT control signal in response to a video intermediate frequency (I.F.) signal.  The I.F. signal is supplied to the inputs of two buffer amplifiers, which couple signals of like phase relationship to two inputs of a discriminator network.  The discriminator network is tuned to the desired frequency of the video I.F. signal, and is responsive to the buffered I.F. signals for causing respective signal voltages to be developed at its inputs which vary differentially in magnitude in response to the frequency deviation of the I.F. signals from the desired I.F. frequency.  The differentially related signals are detected by two peak detector networks for use as AFT control signals.  The buffer amplifiers and peak detectors may be conveniently fabricated on a single I.C. chip.  The discriminator network is coupled to the buffer amplifiers by two external I.C. terminals.

Abstract: ABSTRACT OF THE DISCLOSURE       A control valve for a solar heating system is disclosed.          The valve has a valve body which defines four chambers disposed end to end.  A valve operating rod is movable axially through all four chambers under motor control and carries a valve mem-ber for directing liquid through the valve.  In one position of the valve member, incoming liquid is directed to an outlet for connection to a solar collector and liquid returning from the collector can flow through the valve body and back to the swimming pool.  In the other position of the valve member, the liquid bypasses the collector and is directed back to the pool while liquid in the collector drains back into the valve body through the outlet and is removed by suction from a drain-down chamber in the valve body.

Abstract: ABSTRACT OF THE DISCLOSURE A flange connection for shafts or tubes includes abutting flanges at adjoining ends of the shafts or tubes and also includes aligned bores in the flanges.  Fasteners extend through the bores in directions parallel to the axes of the shafts or tubes.  The fasteners are radially expandable into clamped conditions in which they abut and exert radial pressure against the bores in the flanges.  This eliminates the play between the two adjoining flanges, which play stems from necessary initial clearances between the fasteners and bores to allow for insertion of the fasteners into the bores.
