Abstract: ABSTRACT          A reversing mechanism for a reciprocating pump provided in a common housing or module removably secured to the pump body adjacent to the pump shaft.  The module housing includes top and bottom pieces which slide together with suitable tongue and groove elements.  The top piece houses a reversing valve, and has a slot on the underside thereof for receiving a yoke member of the reversing mechanism.  The sides of the slot form bearing surfaces parallel to the longitudinal axis of the pump shaft.  The yoke slides or reciprocates on these bearing surfaces.  The bottom piece comprises a support for opposed snap-acting springs.  The yoke has a pair of upwardly extending spaced arms for actuating opposite ends of the reversing valve when it reciprocates, and a pair of downwardly extending spaced arms for engaging a transverse pin in the pump shaft as the shaft reciprocates.  A central pin in the yoke couples it to the snap-acting springs.  A special nested bearing structure is provided for the snap-acting springs. The pump is provided with coded inlet and outlet valve cartridges to preclude the improper assembly thereof within the pump housing.

Abstract: ABSTRACT          A method and reagent system is described for differential determination of more that one class of leukocyte populations, using an automatic blood cell analyzer.  The reagent system includes a blood diluent and stromatolysing reagent.  The blood diluent is an osmotically balanced aqueous solution of ingredients for maintaining erythrocyte morphology, blood cell stabilizing, buffering and bacteriostatic action.  The stromatolysing reagent is a mixture of an aqueous solution of quaternary ammonium salts and an additive which is a non-cationic surfactant.  The quaternary ammonium salts, with the additive, serve the purpose of positioning, relative to one another and a volume reference point, the lymphoid and myeloid populations.

Abstract: ABSTRACT: "Integrated radiation detector."     An  integrated radiation detector comprises a number of electrode plates assembled at a mutual distance. The electrode plates comprise slots in which electrically insulating gas-tight strips projecting through all the electrode plates are provided, of which strips one serves as an input window and the remaining strips serve as walls of the detection spaces. For sealing, the strips are interconnected, for example, by means of electrically insulated glued joints. Since the detector need no longer be assembled in a gas-tight housing, connections for the electrodes can be realized in a simple manner. Parts of the electrodes projecting beyond the actual detection space on the side of the input window may serve as a collimator for the incident radiation.

Title: Foam process for recovering underground rock  fragments
Inventor: GARRETT EMMITT G
IPC: E21B21/14
Filed: 1985-10-18
Granted: 1988-03-08
Abstract: ABSTRACT OF THE INVENTION The invention is an improvement in borehole mining which overcomes the conventional problem in hydraulic mining of removing rock fragments and ore from beneath the surface by utilizing a foam/air conveyance technique.  This eliminates the need for a pump and overcomes the drawback of short pump life that is ordinarily encountered when pumps are engaged in pumping fluid slurries containing a high component of fragmented rock.  A foaming agent, such as an organic sulfonic acid surfactant is introduced into the borehole, preferably combined in the water used to dislodge the particles thereby foaming during mining.  The foam containing the entrained particles is removed to the surface by a gas, e.g., air under sufficient pressure and rate to maintain the flow from the well bore.  The foam is broken at the surface by conventional methods and the mined particles recovered.

Abstract: ABSTRACT A mounting arm is disclosed on one end of which a piece of electronic or other equipment is mounted and the other end of which is detachably fastened to the edge of a supporting surface.  The arm has three moving joints that permit the equipment fastened thereto to be moved with multiple degrees of freedom for desired positioning of the equipment.  One joint utilizes a friction washer assembly and a preloaded torsion spring  counterbalancing the weight of the equipment.  The torsion spring tension is adjustable to compensate for differing weight equipment on the one end of the arm.  Another joint utilizes a friction ball joint arrangement having double concentric friction ball surfaces in an assembly that permits multiple degrees of freedom of motion and is easily removed from the remainder of the arm without disassembling the ball joint.

Abstract: ABSTRACT OF THE DISCLOSURE         Telecommunication equipment operating with pulse code modulation and time division multiplexing includes a switching network in which a wide band connection consisting of two or more channels is to be through-connected.  A marking device is disposed at the switching network input and provides markings of the respective contents in the time slots utilized by the connection channels.  A scanning device is arranged at the output of the switching network for detecting a pattern formed by said markings, and with the aid of it determining a possible relative mutual delay between the respective contents of the channels.  The scanning means regulates a device which equalises delays in the channels such as to ensure that after the connection establishment stage the contents of the channels/time slots regain their mutually synchronized positions in spite of the possible mutually relative delay.

Abstract: CONTROL SYSTEM FOR A CONTINUOUS PROCESS   VENTURI ACCELERATED PNEUMATIC PUMP     ABSTRACT OF THE DISCLOSURE         An apparatus for feeding product to a pipeline via a venturi assembly has first and second tanks adapted to separately hold a quantity of product.  The product is fed to the tanks from a supply hopper and enters each tank through an upper opening which accommodates a feed chute.  The open end of each feed chute is closable by a flapper door which is swingable between open and closed positions.  Pressurized air from a compressor is used to selectively close the flapper doors via a set of pressure valves which control the flow of air into the tanks.  The product is fed from each tank to the pipeline through a Y-shaped housing and the venturi assembly.  The housing has respective lower openings for each tank, also clos-able by swingable flapper doors.  When the upper doors are closed by the air pressure, the product is forced out of the tank into the pipeline.  A plurality of sensors are provided for sensing the product level in the tanks and a plurality of detectors are provided for indicating when the flapper doors are closed.  A controller auto-matically monitors the sensors and detectors, and regu-lates feed of the product into the tanks and the pressure valves so as to maintain a continuous duty operation in which product is discharged from one tank as the other tank fills.
