Abstract: ABSTRACT OF THE DISCLOSURE A flexible string of interconnected sheet metal clips of the type which are adapted to hold the end bars of a sinuous or zigzag cushion-supporting spring on the wooden frame of an article of furniture. The clips are disposed in side-by-side relationship and adjacent clips in the string are connected together by a thin flexible web, the thickness of which is reduced by a swaging opera-tion, and which serves to maintain such clips slightly spaced apart. A method of producing such a string of clips which comprises initially fashioning a substantially rigid stick of clips wherein adjacent clips are disposed in contiguous edge-to-edge relationship with adjacent clips being held in their abutting relation by an integral narrow but full thickness web, and subsequently swaging the webs to flatten the same and thus expand the area of the webs so as to spread adjacent clips apart and produce a narrow gap therebetween, the thus expanded webs serving, collectively, to create a string of clips in which adja-cent clips are sufficiently spaced apart that no inter-ference is afforded therebetween, thus enabling the string to be coiled for clip-feeding purposes in connection with a suitable clip-applying tool.

Abstract: TUBULAR PREFORM FOR PACKAGING CONTAINERS                 ABSTRACT OF THE INVENTION         A tubular preform is provided for assemblying bottles or other containers into a package.  The bottles for an integral package are arranged in a group and the tubular preform is placed around the group.  The tubular preform is formed from a lengthy sheet of flexible heat-shrinkable thermoplastic material which is a composite foam and film laminate with the preform having a thermal fusion seal extending in an axial direction.  The preform is flat-folded with a pair of axial pleated folds in diametri-cally opposite sides and then double-folded centrally for use in multiple unit packaging of like containers.  The preform has a primary orientation in a circumferential direction and a secondary orientation in an axial direction making it particularly useful when opened for heat shrinking around a group of like containers.          The tubular preform in heat-shrunken condition forms a tight package convenient for handling, shipment and use.

Abstract: ABSTRACT OF THE DISCLOSURE           A heddle molded from a plastics material is provided with an eye (10) embedded in the heddle body.  The eye (10) can be made from hardened or stainless steel.  The embedding is effected by injecting the plastics material around the thread eye. The thread guiding eye (10) may have a generally meniscal cross-sectional configuration.  The edges of the shape are embedded in the plastics material in order to produce a smooth transfer surface, free of voids and sharp edges.  The elongated portions (22,24) and/or the region (16) of the thread guiding eye (10) are of at least approximately oval cross-sectional configuration.  The heddle of this type combines the advantages of a good wear resistance of the eye portion of a heddle made from metallic material with the advantage of the low weight of a non-metallic heddle.

Abstract: ABSTRACT OF THE DISCLOSURE The invention covers a method and apparatus for sub-jecting a knitted tubular fabric to a dry high temperature in order to reorient the knitted stitch geometry of the fabric while maintaining a predetermined width of the fab-ric under a controlled longitudinal tension condition and allowing the fabric to set while maintaining the controlled longitudinal tension condition. The method involves moving a knitted tubualar fabric over a spreader to spread the fabric into a flattened tubular form of a predeter-mined width while at the same time imparting a lateral tension to the fabric. The inside edges of the form are engaged by a first edge drive to move the form over the spreader towards an edge drive transfer station while maintaining the predetermined width. At that station, the first drive is replaced by a second edge drive while still maintaining the predetermined width. The speed of the first drive is regulated with respect to the second drive in order to control longitudinal tension in the form while engaged by the second drive. The form is then moved by the second drive through a dry heat treat-ing station while maintaining the predetermined width and tension to alter the knitted stitch geometry and remove lateral tension therefrom. The fabric is then removed and allowed to cool and set while engaged by the second drive.

Title: Brake control valve having operator feedback
Inventor: HOEFER WAYNE A
IPC: B60T15/02
Filed: 1980-05-29
Granted: 1982-06-29
Abstract: Brake Control Valve Having Operator Feedback Abstract Conventional fluid control circuits for ser-vice brakes and the like do not always provide an operator with "pedal feel" to indicate the degree of brake engagement.  Such "pedal feel" is particularly desirable in braking systems wherein the brakes thereof are spring-engaged and released by hydraulic fluid pressure.  This invention provides a control valve having an inlet, an outlet, a valve member movable between closed and open positions, and a first spring for urging the valve member towards its closed position.  An operator input is adapted to apply variable input force to the valve to reduce the closing force of the first spring and a second spring is pro-vided for applying a progressively increased opposing force to the operator's input force to provide the operator with "pedal feel" to indicate the degree of engagement of the brakes.  A pair of passages communi-cate the inlet with opposite ends of the valve member to aid in providing such "pedal feel".

The apparatus comprises a chamber having a display tube and containing an indicator liquid. An air passage is connected between the chamber and the selecting device. Air conduits extend from the selecting device to the liquid bodies,whereby these air conduits and dip tubes are   immersed in the liquid bodies. The indicator apparatus contains an air displacing member. Upon operation of the air displacing member the volume of the liquid which level is to be measured present inside the dip tube is expelled due to the air pressure built up inside the conduit. There-after the pressure of the liquid body   is brought into communication with the chamber containing the indicator liquid, such that the level of the indicator liquid inside the display tube is raised to a level corresponding to the level of the selected liquid body.  By means of a pivotably arranged selecting member any one of the liquid bodies may be brought into communication with the indicating apparatus.          The switching member is guided by notches and projections therebetween, such that it moves adjacent to any notch defining a selected position  axially of the air passage such that when the switching member is in any selected position an airtight connection is established between the switching member and the air passage. The switching member is spring biassed against the notches.

Abstract: ABSTRACT Disclosed is a system for automatic control) distribution and convey-ance of food pellets from one or more food supply silos to fish staying within one or more pools or tanks.  The system includes a control unit adapted to selectively actuate any one of the supply silos.  A belt conveyor carries the food from the actuated supply silo to a sieve for removal of crossed pellets and dust.  A belt conveyor carries the food onto an integral weighing device for measuring the amount of food being passed.  The control unit receives in-formation from the associated weighing device for determination and guiding of proper amounts of food for the appropriate tank.  A belt conveyor carries the food to a hopper opening into an injector or a pump having its outlet in communication with a selector valve connectable to each of a plurality of conduits conveying food to a spreader in each tank.  An electrically operated index device is operatively connected to the control unit and is adapted for moving the selector valve to the correct position for delivery of food to the appropriate tank.  Metering devices measure specific weight and temperature of the water within the tanks and are coupled to the control unit, the control unit being adapted to determine the oxygen in the water based on the measurement of the specific weight and temperature, the determination being utilized for automatic calculation of the amount of food required for each tank.
