Abstract: ABSTRACT OF THE DISCLOSURE     A method is disclosed for weaving utilizing a plurality of warp threads and weft threads.  The warp sheds are formed and retained in the warp threads and are moved in the longitudinal direction of the warp threads toward the fell of the woven product.  The method includes the step of continuously inserting a weft thread into each of the moving warp sheds by drawing the weft thread from stationary weft supply packages located outside of the moving warp sheds.   Preferably, the step of con-tinuously inserting a weft thread into each of the moving warp sheds is performed by weft insertion means and further including the steps of inserting the weft thread for the entire interval of time that the weft insertion means are within the moving warp sheds, and supplying the weft insertion means with weft thread from the stationary weft supply packages located outside of the moving warp sheds.  Apparatus is also disclosed for weaving, utilizing a plurality of warp threads and weft threads, com-prising warp shed forming and retaining means for forming and retaining warp sheds in the warp threads, means for moving the warp sheds in the longitudinal direction of the warp threads toward the fell of the woven product, means for continuously inserting a weft thread into each of the moving warp sheds by drawing the weft thread from stationary weft supply packages located outside of the moving warp sheds.  Thus, an improved weft supply and insertion system for warp-wave weaving is provided which utilizes a weft-laying shuttle which is smaller and faster than prior art weft insertion members employed in warp-wave weaving systems in order to provide increased production and to reduce the strain on warp threads by providing smaller shed openings.

Abstract: NOISE REDUCING CONTROL VALVE FOR A HYDRAULIC BRAKE BOOSTER                       ABSTRACT OF THE DISCLOSURE A hydraulic brake booster operatively connects with a pressurized fluid source and a master brake cylinder to convert the pressure within the pressurized fluid source to a power assist to the master brake cylinder during a brake application.  The booster includes a cylindrical housing defining a bore and a piston is slidably mounted in the bore to define a pressure chamber and to operatively connect with the master brake cylinder.  A valve member is slidably disposed within a bore within the piston and is movable upon a brake application to communicate the pressurized fluid source to the pressure chamber which urges the piston into engagement with the master brake cylinder.  In a rest position inlet and outlet openings on the piston communicate fluid through the piston without any transfer of the force within the pressurized fluid to the piston.  Upon movement of the valve member, a land on the valve member cooperates with the piston bore to restrict communi-cation between the Inlet and outlet openings which concurrently increases the communication to the pressure chamber and increases the pressure therein.          Consequently, the piston is pressure responsive to move relative to the housing to engage the master brake cylinder to assist in a brake application. The valve member land includes a first diameter portion and second diameter portion and a recess between the portions to cooperate with the piston bore to quietly restrict the communication between the inlet and outlet openings.

Abstract: FOOD DEHYDRATING MACHINE                     ABSTRACT OF THE DISCLOSURE     A machine for dehydrating food, as an aid toward preservation of food for extended periods of time.  Intake air may be obtained from either the exterior of the machine or a combination of exterior and recycled air.  Intake air is electrically heated and pressurized in a plenum chamber by a fan.  The pressurized and heated air is released in a uniform laminer flow through a set of small openings, thence along horizontally disposed shelves containing the food to be dried.  The air is then selectively discharged into the atmosphere or a portion thereof is recycled and combined with new intake air and again passed over the food to he dehydrated.  The percentage of recycled air is selectively variable over a wide range.  Removable frames support either solid sheets or screens having mesh openings of desired sizes which support the food to be dried.  The choice of a solid sheet or the mesh size depends upon the type of food to be dried.  The intake air is filtered and the electrical heater is temperature controlled by a thermister-triac combination or bi-metallic thermostat which senses the temperature within the plenum and controls the current flowing through the electrical heating element

Abstract: ABSTRACT       A print head for an electroerosion printer is provided with a plurality of electrodes, each displaced laterally along the print line by a predetermined distance and using a multiplexing circuit to successively condition each of said electrodes for energization to produce a record mark.  The circuit further provides for a single line commonly arranged to carry all energizing signals to all electrodes but effec-tive to initiate energization of the electrodes only upon selection by a decoder.  The decoder is operable to condi-tion the individual electrodes in accordance with binary coded signals on a plurality of input lines less in number than the number of electrodes to be controlled. In addition, circuits are provided for energizing a pair of electrodes through a portion of a circuit common to both electrodes by rendering the individual electrodes of the pair responsive only to a particular polarity of electrical signal energiza-tion.  This technique allows the elimination of a number of control leads originally required and reduces the cost of electrode drivers.  Electrode spacing is modified slightly to accommodate the multiplexing control.

Abstract: ABSTRACT OF THE DISCLOSURE            Apparatus for controlling fluid flow through a gate opening includes frame means that define the opening, and guide means which are adapted to retain a gate disc in slidable relation with the opening.  Drawing means for laterally displacing the disc relative to the opening are pivotably connected to lever means having long and short ends.          A fulcrum between the ends is pivotably connected to the disc.  The short end is disposed to bear against a fixed portion of the guide means when the disc is closed, and the long end is connected to the drawing means to obtain a mechanical advantage in drawing pressure when displacing the disc to a partially open position.  The lever means may be a single lever, but a preferred embodiment discloses a pair of levers to apply a uniform drawing pressure on the disc via a hydraulic cylinder that is anchored in a wall of a closed tank which contains the apparatus.  A piston rod of the cylinder faces outwardly of the tank to avoid contamination and subsequent corrosion and is connected to the lever means by rods which are slidably sealed in passages leading through the wall.

Granted: 1982-06-29
Abstract: ABSTRACT OF THE DISCLOSURE A process for producing propylene-ethylene block copolymers by a three-step polymerization technique using a stereoregular catalyst is provided herein.  The first-step polymerization is carried out by supplying propylene alone or a propylene/ethylene mixture so that the ethylene/propylene reaction ratio is 6/94 or less, thereby polymerizing 60 to 95% by weight of the total polymerization amount.  The second-step polymerization is carried out by sup-plying a propylene/ethylene mixture so that the ethylene/propylene reaction ratio is 15/85 to 79/21, thereby polymerizing 1 to 20% by weight of the total polymerization amount.  The third-step polymerization is carried out by sup-plying a propylene/ethylene mixture so that the ethylene/propylene reaction ratio is 50/50 to 89/11, thereby polymerizing 4 to 35% by weight of the total polymerization amount.  The ethylene/propylene reaction ratio in the third step is made larger than that in the second step.  The novel process can give propylene-ethylene block copolymers markedly well balanced in impact strength, stiffness, transparency and impact blushing.

Abstract: 47,667 METHOD OF SEPARATING IRON FROM URANIUM       ABSTRACT OF THE DISCLOSURE In uranium recovery by solvent extraction pro-cesses, uranium is separated from iron in an organic extract by stripping the extract with a dilute aqueous solution containing carbonate ions, hydroxyl ions, and ammonium or alkali metal ions.  The iron precipitates during stripping as Fe2O3?nH2O which is filtered off.  The uranium is then precipitated from the filtrate as ammonium diuranate by lowering the pH to about 2 to decompose the carbonate then raising it with ammonia or ammonium hydroxide to about 7 or as UO3?2H2O by steam stripping.
