Title: Testing device for pilot valves
Inventor: MCNEELY MICHAEL D
IPC: F16K37/00
Filed: 1987-05-13
Granted: 1991-10-15
Abstract: Abstract of the Disclosure A testing device (22) for a non-flowing pilot valve-(20) controlling a main relief valve (13) and simulating the action of the relief valve (13) without affecting normal operation of the relief valve (13).  The testing device body (84) has a test fluid source (42) releasably connected thereto and includes a pis-ton valve element (112) mounted in a valve chamber (106) for movement to an unseated vent position upon the test fluid pressure reaching a predetermined high which is usually similar to the set point operating fluid pressure at which the main relief valve (13) will actuate.  For return of piston valve element (112) to a seated position after a reduction of the test fluid pressure by venting, a relatively large diameter end face (128) is exposed to fluid pressure from an intermediate fluid chamber (78) of the pilot valve (20) which is in fluid communication with the dome (14) of the pressure relief valve (13).  A relatively small fluid pressure responsive area of piston (113) outwardly of small diameter O-ring (120) is exposed to test fluid pressure.

Title: Method and apparatus to uniformly feed plug flow material from storage to a line operation
Inventor: FORESMAN JAMES D
IPC: B01F15/02
Filed: 1987-10-23
Granted: 1992-06-16
Abstract: ABSTRACT OF THE DISCLOSURE         An inlet device comprises an inlet chute, an inlet hop-per pan and two blades in counter rotation above the flights of a plug screw feeder.  The blades are housed in a pan which sealingly connects to a cast plug screw liner which is a U-shaped trough for the plug screw.  The blades are driven by shafts supported in pillow block bearings fastened to a main housing.  The main hous-ing holds a gear train driven by a right angle gearmotor.  The gearmotor is also mounted on the main housing and drives abutting gears in counter rotation above the flights of the plug screw.  A storage bin, reservoir, worm conveyor or some type of pulsating feeding arrangement feeds directly into the instant inlet device.          The inlet device then feeds into line operations, e.g., a pulp refiner line operation.

Granted: 1991-08-27
Abstract: VACUUM CLEANER WITH PERFORMANCE MONITORING SYSTEM      Abstract of the Disclosure A canister type vacuum cleaner includes a floor cleaning unit and a canister unit interconnected by a wand and hose assembly.  The canister unit has a dust collection bag mounted in a dust collecting compartment by a dust bag mount.  A suction fan evacuates the air within the dust col-lecting compartment causing dirt laden air to flow from the floor cleaning unit through the wand and hose assembly and into the dust bag through an intake port formed in the dust bag mount.  The air is exhausted from the canister unit through a discharge port.  A performance monitoring and indicating system provides information as to the operative condition of the vacuum cleaner by means of an "OK" light, a "No Bag" light, a "Check Bag" light and a "Check Hose" light.  A dust bag sensor senses the differential pressure between the intake port and the dust collecting compartment and is actuated when a functional dust bag is properly mounted on the dust bag mount.  A discharge sensor senses the differential pressure between the discharge port and the dust collecting compartment and an intake sensor senses the differential pressure between the outside of the vacuum cleaner and the intake port.  The actuation of the intake and discharge sensors provide informa-tion to indicate when the dust bag has become too clogged or that a restriction exists in the wand and hose assembly.

Abstract: Title: QUARTER POINT Return MECHANISM FOR      MANUALLY OPERATED REVOLVING DOORS                 ABSTRACT OF THE DISCLOSURE    This invention  relates  to  a  quarter  point  return mechanism for a manually driven revolving door.   Revolving door leaves extending outwardly from a shaft are partially enclosed  between  opposed  curved  sidewalls.    The  return mechanism has a number of elements including an actuator, a rack arranged to be linearedly displaced by the actuator, and a pinion engaging the rack and being rotatable in opposite directions.  The pinion is rotatably connected to the central shaft  of  the door.    When  the pinion  is rotated  in one direction, rotation is transmitted to the shaft.   When the pinion is rotated in the opposite direction, the rotation is not  transmitted  to  the  shaft.    Also  included  is  a circumferential displacement  sensor  which  operates  the actuator when the outer ends of the door leaves are in a position circumferentially displaced from the sidewalls.  The return mechanism returns the door leaves to a rest position in which the door leaves are  in contact with the curved sidewalls.   In an alternate embodiment the rack and pinion combination  is  replaced  by  a  direct  connection  of  the actuator to a one-way clutch.  The clutch is then connected to the shaft.

Granted: 1993-10-12
Abstract: ABSTRACT OF THE DISCLOSURE         A  lickerin  and  feed  mechanism  create  a  supply  of individual  short  fibers  which  follow the  rotation  of  the lickerin.  These fibers are deflected from the lickerin in the form of a stream by means of a plate arranged parallel to the lickerin.  A conveying screen  intercepts the stream of fibers and accumulates them into a web without the use of a high pressure stream of air to doff the fibers from the lickerin or to capture fibers on the conveyor.   Further, the housing for the apparatus is opened so that there are no seals to compress the web after it is produced.  A feed tray located next to the lickerin can be used to include other particulate materials (fiber or granules) in the main fiber stream and a tapering of the deflector plate can separate the component of the blended fiber-particulate material stream into layers in the resulting web distinguished by particle weight.

Abstract: ABSTRACT OF THE DISCLOSURE   A distributed digital data processing system includes a plurality of nodes which communicate over a network.  A node maintains one or more objects, each of which may be a file, that is, an addressable unit in the system, such as a program, database, text file, or the like, or a directory which may contain one or more files or other directories. One node maintains a naming service which associates each object in the system with one or more protocol towers.  Each protocol tower identifies the object name and a series of entries each identifying a name for each of the protocol layers, along with the communications parameters and address information, to be used in communicating with the object.  When a node requires access to an object maintained by another node, it first retrieves from the naming service the protocol towers for the object.  The node also maintains a tower identifying the names of each of the protocols over which it can communicate.          The node then compares the protocol names in the retrieved protocol towers with the protocol names over which it can communicate.  If the protocol names in a retrieved tower match the protocol names in the node's tower, the node uses the communications parameters and address information in future communications with the object.  If the node is unable to identify a retrieved protocol tower which matches its supported tower or towers, it is unable to communicate with the object.

The power supply is disabled in response to the presence of a predetermined voltage difference between the sensor terminal and the input terminal of th one bus bar indicating the presence of a break in the connector section of the bus bar so as to prevent the development of an arc across the break.

Abstract: Abstract An improved method and apparatus for controlling the flow of breathing gas, such as oxygen, to a person can be limited to the portion of such person's inspira-tion cycle thereby reducing the consumption of breathing gas to at least half and possibly less to extend the life of the gas supply and reduce the cost per unit time. A bidirectional dynamic mass sensor measures gas flow rate and direction yielding a corresponding proportional output voltage signal applied to a system controller indicating system failure, apnea, flaw rate and duration, consumption, and controlling gas flow duration in each breathing cycle.
