Abstract: ABSTRACT    A linear type of compressor wherein a housing section, for enclosing a crankshaft and pinions of a counterbalancing synchronizer, has axially extending support means for the pinions formed integrally therewith through an inner flange also integral with the housing section, so that the holes for the pinion shafts may be formed in the support means when the hole in the housing for the crankshaft is formed. This assures the making of all of the holes exactly parallel and avoids time-consuming assembly work, experienced in prior art compressor manufacturing, when the housing sections are put together. By providing a large open-ing through the upper portion of the support means or through the bottom of the housing an axial bore may be made to receive a piston type of crosshead. By cutting down on the number of compressor parts and the manufacturing tolerances involved in the manufacture of the parts and the use of U-shaped members as guides for gear racks and as retainers for the pinion shafts, a further saving in manufacturing cost is obtained.

Abstract: 14                  48,078 ABSTRACT OF THE DISCLOSURE         A reversible gerotor pump having unidirectional fluid flow therefrom dictated by a movable eccentric ring member 30 for positioning the rotor 46 of the pump gear-set 44 in either one of two axially eccentric positions depending upon  the  direction  of  rotation  of the drive shaft  20  to  the pump.   Movement of  the eccentric ring member from one such position to the other position upon a reversel  of direction  of  the drive shaft is caused by check valve means 70 associated with the pump inlet 68 so that, if reverse rotation of the drive shaft momentarily causes reverse flow of the pumped fluid (e.g., causes the fluid to exit through the inlet)  the check valve closes and establishes a hydraulic lock between the gear-set and forces  the  eccentric  ring member to move from the one position  to  the  other eccentric position whereupon the fluid is once again caused to be discharged through the normal pump outlet 64 and enter through the inlet.  Under these  conditions,  the  check valve  opens  to permit  the pumped fluid to continue to enter the pump.

Abstract: The invention discloses a "three-point" coupling suitable for use both at the front and at the rear of an industrial, agricultural, public works or forestry vehicle, e.g., a tractor. To each bracket of a crossbar attached to a tractor there are pivoted on one side, the rod of a jack and on the other hand firstly a traction rod and secondly one end of a device of adjustable length, the other end of which is pivoted to the associated bar. The two jacks are connected mutually and to a common hydraulic energy source, and the stroke of each piston can be limited in order to determine the final vertical position of the bars by a shutter block carried by one of the jacks and actuated by an adjustable stop fitted on a rod integral with the rod of the jack coming into contact with an actuating push rod of the block.

Abstract: IMPROVED TANDEM LONG STROKE RECIPROCATING             MUD PUMP ASSEMBLY                  ABSTRACT OF THE DISCLOSURE            A diverse fluid pump assembly including a pair of parallel, reciprocating piston-cylinder, motor-pump combinations.          The motor-pump combinations are oppositely arranged so that one is pumping while the other is charging.  Motor reversal is accomplished through a unique, hydraulically actuated spool valve which is slaved to the common piston rods of the respective, tandem motor-pump combinations.  The invention is intended for use primarily as a mud pump for oil well servicing or drilling rigs.  Principal components are easily broken down for replacement because of wear and/or size considerations.  In a preferred embodiment, the hydraulically actuated spool valve is hydraulically slaved to the motors to effect motor reversal.          A unique floating stuffing box is provided on the motor side of each combination which accomodates lateral rod shifting while maintaining a fluid tight seal.  The spool valve operates smoothly through five distinct stages during motor reversal thus eliminating any need for a pulsation dampener.

Abstract: Abstract The disclosure is directed to an improved liner assembly for the cylindrical  drum or shell  of an ore grinding mill.  The liner assembly comprises a plurality of holder segments formed from material which is resistant to impact, and a plurality of wear inserts for the holder segments, which are formed from material which is resis-tant to abrasion.  Each of the holder segments defines a mounting surface constructed for mounting engagement with the inner surface of the cylindrical shell, and an inward-ly facing grinding surface defining a longitudinal channel extending from one end of the holder segment to the other and opening upwardly or toward the  shell center.  The longitudinal  channel  is  closed  at the bottom,  and is defined  by  longitudinal  sides  or  faces  that  converge toward the grinding surface of the segment.   The wear insert has a transverse cross section which conforms to the channel,  and upon insertion into the channel is re-tained by the complementing tapered configurations.  The holder segments  include  a plurality of bridge elements integrally cast over the top of the channel in transverse relation to maintain the proper spacing relation between the channel sides during the casting process.  The bridge elements  wear  away  relatively  quickly  during  the  ore grinding process to fully expose the top surface of the wear inserts.  With the holder segments mounted in axial rows,  the end-to-end wear inserts present a continuous wear surface over the entire axial length of the liner assembly.

Abstract: ABSTRACT Apparatus for shaping glass sheets to a complicated shape includ-ing a longitudinal component of bend and a complicated transverse component of bend within a tunnel-like lehr.  An outline mold with guides for align-ing one or more glass sheets for proper orientation and alignment thereon supports the glass while the glass is bent by gravity sagging to provide a longitudinal component of bend and to deliver the sag bent glass to a position between upper and lower pressing molds having complementary shaping surfaces conforming to a complicated bend including a complicated transverse bend component.  Special alignment means are provided to orient and align the outline mold relative to said pressing molds so that the lower pressing mold can lift the sag bent glass off the outline mold into engagement with the upper pressing mold to impress the transverse bend component and return the glass with its complicated shape to the outline mold for controlled cooling and removal from the lehr.  When two glass sheets are shaped simultaneously in this manner, they conform exactly to the shape of each other so closely that they can be laminated readily to form a laminated windshield of complicated shape for installation in exact registration with a shaped mounting frame of a vehicle. The upper pressing mold may be omitted in cases where thin glass sheets are bent to relatively shallow curvatures which may involve compli-cated shapes and/or outlines.

Abstract: TITLE OF THE INVENTION        ELECTRONICALLY CONTROLLED FLUID INJECTION SYSTEM        FOR AN INTERNAL COMBUSTION ENGINE   ABSTRACT OF THE DISCLOSURE         A fluid injection system for an internal combustion engine such as a spark-ignition or compression-ignition engine in which an injection nozzle injects a finely divided spray of fluid, such as water or a water solution, into the engine in response to a flow of atomizing air.  The nozzle is connected to a fluid supply reservoir and to the outlet line of an air-injection pump connected to and controlled by an electronic circuit that includes a pick-up coupled to the ignition system of the engine.  The electronic circuit responds to spark plug firing rate, which is proportional to engine speed, and to the amplitude of the voltage across the spark plug gap, which is proportional to engine load, and varies, respectively, the pump stroke rate and the pump stroke length accordingly.  As a result, the flow of atomizing air to the nozzle and therefore the rate and magnitude of water injection is responsive to engine speed and load.
