Abstract: Abstract of the Disclosure An improved return line filter is provided for use with a fluid system having a fluid reservoir which is at least partly filled with a fluid.  The return line filter comprises an elongated housing having an open top and a partially open bottom and in which the housing is positioned within the reservoir so that the lower end of the housing is submerged in the reservoir fluid.  A fluid inlet is formed on the lower end of the housing.  A filter assembly is provided for use with the housing and comprises a tubular filter element open at each end and a holder assembly which is detachably secured to one axial end of the filter element.  The entire filter assembly is insertable through the open top of the housing so that the tubular filter element is positioned co-axially around and spaced radially outwardly from a portion extending upwardly from the housing thus forming an annular chamber therebetween.  Fluid seals sealingly connect both axial ends of the filter element with the housing portion while a fluid passageway fluidly connects the housing inlet with the annular inlet chamber.  In addition, a deflection and antifoam tube secured to the holder assembly is positioned coaxially around and spaced radially outwardly from the filter element so that fluid flow from the filter element is deflected downwardly toward the partially open bottom of the housing.  This construction for the filter assembly creates a reverse fluid flow in which the fluid must first flow upwardly from the bottom of the housing, out through the filter element and subsequently down through the lower open end of the housing.

Granted: 1982-09-28
Abstract: ABSTRACT OF THE DISCLOSURE     A valveless pump system having two moving parts consist-ing of a cylinder with a piston therein defining a pump chamber.          An inlet part communicates with a dip tube which extends into a container and permits the product in the container to pass into the pump chamber.  An outlet port allows for the product thus drawn to be dispensed from the pump chamber.  The pump is actu-ated by pressure directed axially on the piston, forcing it into the cylinder.  Fitted with a return device the piston is allowed to reciprocate in the cylinder alternating between a suction and compression stroke.  During the suction stroke product is drawn into the pump chamber by way of the inlet port while the com-pression stroke provides for the dispensing of the product thus drawn via the outlet port.  The system is equipped with passages and channels sufficient to accomplish the operation of drawing and dispensing the product in addition to providing for the vent-ing of the container.  The suction stroke provides for air to be drawn through the outlet part from the ambient into the pump cha? ber, advantageously removing any residual product from the outle? part where this is desirable.  In certain applications the air i? drawn into the pump chamber to assist in the dispensing of the product during the compression stroke.  The introduction of air into the pump chamber also assures the presence of an air pocket therein, thereby maintaining a resiliency in the system thereby preventing piston "hang up".    Embodiments of the pump system are disclosed having a vertical pump axis equipped with a?verti-cally reciprocal finger actuated button or having either a ver-tical or horizontal axis with a trigger actuator.  Different cylinder and piston configurations are disclosed facilitating commercial applications of the system.

Abstract: ABSTRACT OF THE DISCLOSURE         A portable fluorescent tube assembly is disclosed that is substantially all plastic and comprises improved end socket construction for the tube.  In one form, an end socket comprises a support body having openings adapted to make an electrical connection therein with pins of the fluorescent tube.  Radially extending fingers on the body tend to center it as desired.  A rearward extension of the body has a trans-versely disposed aperture.  Hollow socket members embrace the support body and have connecting sections which meet one another through the aperture of the rearward extension.          Fastening means extend through the connecting sections of the socket members and the aperture to hold the socket construction in assembly.  Optionally, one socket construction can contain a starter switch for the fluorescent tube and electrical leads needed to energize the tube.  Preferably, the electrical plug for the electrical leads and the ballast for the fluorescent tube are combined in one integral unit remote from the tube to relieve the assembly of the weight of the relatively heavy ballast.

Abstract: Abstract of the Disclosure An improved method and apparatus is provided to control the rate at which fuel is supplied to an engine by a fuel pump.  The fuel pump has an output pressure which varies with pump operating speed in accordance with different curves of a series of curves.  In order to determine which curve of the series of curves is representative of the manner in which the fuel pump output varies with pump speed at one time, the fuel pump operating speed and output pressure are simultaneously sensed to determine a point on an initial curve.  The fuel pump operating speed is subsequently varied in accordance with the initial curve to provide a desired variation in fuel pump output to the engine.  The fuel pump operating speed and output pressure are periodically simultaneously sensed to determine if the fuel pump output still varies in accordance with the initial curve or has changed to a second curve of the series of curves.  If it is determined that a second curve is representative of the manner in which the fuel pump output varies with pump speed, the fuel pump operating speed is subsequently varied In accordance with the second curve.

Abstract: A B S T R A C T            MULTI-PROGRAMMING DATA PROCESSING      SYSTEM PROCESS SUSPENSION            Each process in a multi-process computing system using so-called capabilities may have associated with it a process dumpstack protected by the capability mechanism.  The functions of this dumpstack are (i) to provide the state of the process at the point at which it was suspended and (ii) to stack (or nest) information relating to the invoked procedures (i.e. sub-routines) of the process.  Thus there is a fixed sized portion containing principally the machine registers, the indicators and the watchdog timer values and a variable sized portion containing information related to each nested procedure.  Each stack link is of fixed size and contains three items:- relativised instruction address, the code block capability and process capability pointer list block capability.  This arrangement is enhanced to allow two additional classes of information to be stored in each link namely (a) an indication of the data and capability registers preserved during the domain change procedure and (b) descriptors for local storage segments.  The use of descriptors for local storage allows a pool of storage particular to the process to be allocated on a segmented basis with the security of the capability mechanism extended into that local storage area.  The descriptors for local storage segments resemble closely SCT entries (i.e. they contain sumcheck, base and limit values) and they are relative to a new protected stack, the local store stack, which is referenced by a hidden capability register C(L). The processor module is provided with a new instruction "subset local store" for use in local store segment allocation and - ii -automatic de-allocation occurs when a return is made from the procedure in which the local segment was allocated.  Such allocation and de-allocation mechanisms use the indications which takes the form of a primary descriptor held in the most sigificant eight bits of the IAR word.  This descriptor is allocated as follows:- (i) zero, no stacked registers or local segments allocated, (ii) m.s.b. = 1, stacked registers to be passed and (iii) l.s.b. 1-7 = 1, indicates the number of local store segments allocated.  Associated with the stacked register set is a one word descriptor which indicates the registers stacked.

Abstract: ABSTRACT OF THE DISCLOSURE    A scintillation camera including a memory having a plurality of addresses corresponding to the elements of the matrix-like divided image of a scintigram and to the points in the camera head for registering radiation.  The addresses in the memory are designated to correspond to incidence position signals of points of radiation determined by a position-calculating circuit.  A pulse-height analyzer also receives the signals of radiation registered by the camera head and issues an unblanking signal to control apparatus if the signal is significantly stronger than background noise.  The control apparatus, triggered by the unblanking signal, initiates the comparison of the content of the designated address in memory with a predetermined minimum value of radiation in a comparator and when the content is less than the minimum value the control apparatus adds one to the content and restores the increased content to the designated address.          When the content is at least equal to the minimum value, the con-trol apparatus issues the unblanking signal to display apparatus to display the radiation at the designated address.  A timer stops access of the unblanking signals to the display apparatus after a preset time, thus excluding display at those elements of the display wherein the accumulated radiation is less than the minimum at the expiration of the preset time.
