Title: Positive displacement metering pump
Inventor: HARDMAN JAMES V
IPC: F04B53/10

Granted: 1979-02-13
Abstract: Abstract of the Disclosure A metering pump including a pump body having a bore for receiving a flowable composition to be dispensed, feed inlet means communicating with the bore, and spaced outlet means including a check valve, for discharging the composition.  A pressure chamber is defined intermediate the pump inlet and outlet.  The chamber has an inlet, and an outlet communicating with the pump outlet through the check valve.  A piston is mounted for axial recipro-cation in the bore between a first position at which the piston is withdrawn from the pressure chamber inlet, and a second position at which the piston passes at least partially into such inlet.  The pressure chamber inlet is bounded by sealing means including an annular sealing surface which converges in the direction of the pressure chamber, to a diameter less than that of the piston, whereby the surface may slideingly engage and seal with the piston upon the latter entering the pressure chamber.  The sealing surface is elastically dilateable away from the axis of the bore, to maintain the seal about the piston during its entry and withdrawal from the pressure chamber and to enable compensation for wear.  At least one other surface of the sealing means is accessible to the pressure chamber interior, and is elastically coupled to the backside of the sealing surface.  In consequence, the increasing pressure developed by movement of the piston into the pressure chamber, acting through the accessible surface, increases the sealing forces between the sealing surface and piston.

Abstract: ADJUSTABLE BULKHEAD                 ABSTRACT OF DISCLOSURE The present invention relates to an adjustable bulkhead for preventing the movement of lading within a lading carrying vehicle, such as a railway car, and more particularly, relates to a mechanical bulkhead having a structural frame member adapted to be mounted in a stationary position, with one or more expandable panels connected to said frame member by clevis linkeges which are operated by one or more hydraulic cylinders.  By the use of an air-operated hydraulic pump fed by a constant volume air reservoir of a size chosen so that as the bulkhead expands, the pressure of the air supplied to the hy-draulic pump, and thus, the oil pressure in the hydraulic cylinder, will decrease as the natural mechanical advantage of the clevis type linkage comes into play, and a substantially uniform force can be kept on the lading regardless of the amount of the expansion of the bulkhead.      The use of the hydraulic cylinder permits a near in-stant response to the movement of the lading, with substantially in-stantaneous expansion of the movable bulkhead panels to take up slack and to prevent the development of voids that were present with the old airbag bulkhead systems, such voids being primarily responsible for cargo damage.  The provision of a check valve in the hydraulic line also prevents any backward movement of the panels, and thus, the present invention provides a bulkhead which can initially expand to compress a lading, will maintain a uniform force on the lading, and will quickly take up any slack which develops in the lading, but which will not retract until the operator desires it to, and thus, substantially eliminates the possibility of any damage to the lading being carried from having voids develop in the lading due to quick starts and stops of the vehicle, into which cargo can fall and be crushed by further motion of the vehicle.

Abstract: Abstract of the Disclosure The invention relates to the new antibiotic Lysolipin, including two components X and I, and derivatives thereof. Lysolipin is formed when the strain Streptomyces violaceoniger (Waksman et Curtis) Waksman et Henrici T? 96, which strain has been deposited under the reference NRRL 8097 at the Northern Regional Laboratory, U.S. Department of Agriculture, Peoria, Illinois, is cultured in a nutrient medium. The structure of Lysolipin I has been elucidated; it has the formula   Lysolipin and its derivatives have antibacterial action and an action against yeast - like fungi, such as Candida albicans. Its antibiotic action probably depends on an inhibition of the cell wall synthesis.

Abstract: AN IMPROVED SULFUR DIOXIDE SCRUBBING SYSTEM    ABSTRACT OF THE DISCLOSURE     The refractory, non-regenerable alkali metal sulfate produced in a regenerative SO2 scrubbing system which uses thiosulfate-rich solutions of the alkali metal SO2 absorbent is removed from the system by precipitation after regeneration of the alkali metal absorbent but before re-entry into the scrubbing circuit, based upon the discovery that the alkali metal sulfate is least soluble in the multi-component solution leaving the regenerator than anywhere else in the entire system.  An additional feature of the invention is the recovery of the precipitated sulfate in an odor-free state by washing with a slip-stream of the spent absorbent solution.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention concerns a foil for electrically or mechanically operated dry shavers.         More especially the invention concerns a foil made from a sheet having perforations and bars between the perforations, the bars being dished in cross-sectional profile, the base of the dished profile being flat and of uniform thickness (t) while the edges extend at an obtuse angle .alpha. to the base, terminating in coplanar faces parallel to the base, the width of the face (w) being not greater than the thickness (t).         The foils are especially suitable for battery operated razors, in which the reduced width (w) leads to reduced power consumption and longer battery life.

Abstract: ABSTRACT           A system for examining a body through the use of X-rays or other penetrating radiation includes a means for moving a beam of radiation over a body to be examined and a detector for detecting the intensity of the non-absorbed or body-exiting portion of the beam.  The system is formed into a dynamic closed loop by comparing the detected beam intensi-ty with a given reference signal and utilizing the error sig-nal so obtained to dynamically vary the body-incident inten-sity, or body-incident  intensity and wavelength, of the beam in such a manner as to hold the detected intensity at a con-stant value.  With the detected intensity held constant, the control signal which dictates the body-incident intensity, or body-incident intensity and wavelength, of the beam becomes a function of the transmissivity of that portion of the body through which the path of the beam instantaneously passes. As the beam is scanned over the body, the beam control signal is supplied to a computer or other utilization device which ex-tracts transmissivity data therefrom and processes such data to compose a pictorial or other graphic display.

Abstract: Abstract of the Disclosure A D.C. controlled attenuator which is particularly useful as a D.C. controlled video attenuation circuit providing three tracking channels that can be used as a tracking contrast control in an RGB monitor includes an integrated circuit having at least six MOS field effect transistors on a common substrate, the transistors being of N-channel and P-channel type and being arranged in three groups of two each connected in com-plementary symmetry.  In each group the gate electrodes of the N-channel and P-channel transistors are connected together, their drain electrodes are connected together and a source of D.C. potential is connected between their source electrodes in parallel.  A variable resistor is connected between the gate electrodes of the transistors of a group and the drain electrodes of those transistors providing a feed forward signal path that also preferably includes a variable inductance coil.  Input signals are supplied to the gate electrodes of the transistors, and the magnitude of the D.C. potential of the source of D.C. potential can be varied.  By adjusting the value of the resistor in the feed forward signal path, cancellation of the signal at the drain junction of the COS MOS amplifier can be achieved at maximum gain of the amplifier, so that when the gain of the amplifier is reduced, less attenuation results.
