Title: Universal joint with improved lubrication
Inventor: MAYHEW ROGER D
IPC: F16D3/26
Filed: 1987-05-12
Granted: 1992-07-07
Abstract: Abstract of the Disclosure An improved lubrication passageway for a universal joint having a pair of yokes is disclosed.  The yokes are pivotally connected to one another and each has an axis of rotation.  An annular groove is formed in an arm of one of the yokes in a plane which is spaced apart from the axis of rotation of the yoke and perpendicular to an imaginary line which is normal to the axis. A first passageway provides lubricant to the side of the groove which is distal from the centering apparatus.  A second passage-way provides lubricant from the side of the groove proximate to the centering apparatus to the centering apparatus.  The annular groove acts as a check valve to prevent lubricant from flowing out of the centering apparatus when the joint is rotating.  A system for lubricating a centering plate and bearings for the universal joint is also disclosed.

Abstract: ABSTRACT A stretcher for supporting incapacitated individuals that may be selectively positioned by two pairs of hydraulic cylinders located near each end thereof is shown.  The piston rods associated with each such pair, located together with their respective cylinders on opposite sides of the stretcher, are mechanically interconnected for stability, while the cylinders associated with such pairs are hydraulically interconnected so that the cylinders can operate in tandem.  The cylinder pairs each have their own pumps, operated simultaneously by a foot lever, as well as remotely controlled valving, enabling the pairs to be operated together, or independently of each other. Included pressure relief valving avoids equipment-damaging, excessive hydraulic pressures, and certain adjustable components of the stretcher are provided with spring-loaded tapered lock assemblies which allow the components to be secured in selected positions.  X-ray tops are also taught which can be used in conjunction with the stretcher for X-ray examination.

Title: Liquid proportioner with filtering system
Inventor: FINNELL JAMES H
IPC: B01F5/04
Filed: 1988-03-30
Granted: 1991-11-05
Abstract: LIQUID PROPORTIONER WITH FILTERING SYSTEM               ABSTRACT OF THE DISCLOSURE           A liquid proportioner is disclosed in which the interior of a flexible bladder located within a tank provides a concentrate reservoir and a dilutant reservoir is provided exteriorly of the bladder. Because the bladder is flexible, the concentrate and the dilutant are maintained at the same pressure.  A first orifice system connects with the dilutant reser-voir and a second orifice system connects with the concentrate reservoir.  An elongated, tubular filter is located within the concentrate reservoir and oper-ates to remove any solids from the concentrate which would otherwise cause clogging of the concentrate orifice system.  Because the pressure of the dilutant and concentrate is maintained equal, the level of the concentrate within the concentrate reservoir remains above the upper end of the filter until the supply of concentrate is virtually exhausted.  This ensures that the total area of the filter is available for filter-ing during the entire operation of the proportioner.

Inventor: CRAWFORD DUFFER B
IPC: C07C7/09
Filed: 1988-05-26
Granted: 1991-09-03
Abstract: ABSTRACT      Heavy components of hydrocarbon  gas  mixtures are recovered through partial condensation of  a  first  portion of the starting gas by  indirect  heat  exchange  with  a  refrigerant wherein the condensate formed is entrained in  the gas stream.  The condensate is separated  from  the  resulting  partially condensed, two-phase mixture and the separated condensate is then thermally stripped of light components by heat  exchange with  a  second portion of the starting gas which  is  thereby  also partially condensed.  Heavy components from the starting gas mixture are recovered as stripped hydrocarbon condensate.

Granted: 1991-10-22
Abstract: ABSTRACT OF THE DISCLOSURE    A load side phase control circuit is used in conjunction with a conventional fluorescent light ballast (step-up autotransformer) and an isolation transformer to achieve fluorescent lamp brightness control. A resistor and capacitor connected in series shunt the phase control circuit to maintain low level illumination even when the phase control circuit is nonconducting and also provide a transient suppression when the phase control circuit switches to a conducting state. The circuit is especially suited to printed circuit board preassembly and subsequent connection to the lamp and ballast by a one step crimping operation. The resulting fluorescent lamp system - of the rapid start type - is well suited for use as a task light where the lamp is mounted relatively close to an underlying work area and receives power from a conventional outlet.

An apparatus for separating a feed liquid into a concentrate and a permeate  fraction  by membrane  filtration  comprises  an  array  of cassette frames  (1-5)  separated by intermediate plates (10).  The array is adapted to be clamped together in its longitudinal direc-tion and loosened,  as  required,  to remove any selected cassette frame.  Each cassette frame  (1-5)  contains  a filtration unit  (6) comprising a stack of membranes,  in which a first  flow passage system is provided which connects two free zones (7,8) within the cassette frame, said free zones being so connected as to establish a series or parallel or combined series and parallel flow from a feed liquid inlet (25) to a concentrate outlet (25).  In each stack of membranes a second system of flow passages is also provided, which is isolated from said first system and serves to conduct permeate penetrated through the membranes to at least one separate outlet (9) from each filtration unit (6).            In the method of making a filtration unit, envelope-shaped membrane units (62) are placed in a stack, a curable liquid binder (101) is introduced between the membrane units from at least one surface of the filtration unit to a predetermined depth (a), and upon curing of the binder a layer of the binder together with the marginal portions of the edges of the membrane units embedded therein is removed, such as by surface cutting or machining, up to a depth (b) smaller than the depth (a).
