Title: Flow meter
Inventor: GERLACH CHARLES R
IPC: G01F1/22
Filed: 1975-05-13
Granted: 1978-10-24
Abstract: ABSTRACT OF THE DISCLOSURE A flow meter is described which provides a linear read-out signal proportional to flow therethrough and which can compen-sate for changes in the viscosity of the fluid.  The flow meter is designed for in-line installation.  The working element consists of two spring-restrained pistons mounted on a common stem.  One of the pistons moves axially inside a contoured cylinder providing a nonlinear area-displacement characteristic.  The cylinder con-tour, and the nonlinear area displacement characteristic thereof, is designed to produce a linear relationship between the piston displacement and fluid flow rate.  The second piston provides the viscosity-compensating correction force to give an accurate flow indication in the presence of changes in fluid viscosity.  The stem upon which the pistons are mounted extends into a calibrated read-out scale to provide an indication of flow rate as a function of piston displacement.

Title: Method of indicating a load placed on a load-carrying vehicle platform and corresponding apparatus
Inventor: NORDBERG CARL-ERIC B
IPC: G01G19/10
Filed: 1975-07-14
Granted: 1978-12-19
Abstract: ABSTRACT       This invention relates to a platform which can be displaced relatively to the frame side members of a load-carrying vehicle and which in the unloaded state is situated at the theoretical centre of gravity of the vehicle load.          A load placed on the platform results firstly in an increase in pressure in a tipping cylinder disposed at the centre of gravity of the vehicle load and secondly a torque about the theoretical centre of gravity of the vehicle load if the centre of gravity of the load does not lie thereat.  A signal proportion-al to such torque then controls a platform-displacing system to displace the platform towards the theoretical centre of gravity of the vehicle load.  The pressure rise occurring in the tipping cylinder forms an indication of the weight of the load and can then be noted and recorded.

Abstract: ABSTRACT OF THE DISCLOSURE       Tetrahedrite ore concentrate, sodium sulfide added as such or formed in situ, calcium values preferably supplied as lime, and a reducing agent, e.g., coke, are smelted for a period sufficient to convert a major portion or substantially all of the antimony to a water-soluble sodium compound of antimony and sulfur and a major portion or substantially all of the arsenic also con-tained in the concentrate to a water-insoluble calcium compound of arsenic and oxygen.  The sodium sulfide is incorporated into the charge for the smelting in an amount sufficient to convert at least a major portion of the antimony into the water-soluble sodium compound of antimony and sulfur; and the lime is incorporat-ed into the smelting charge in amount sufficient to convert at least a major portion of the arsenic into the water-insoluble calcium compound of arsenic and oxygen.  A soda matte obtained from the smelting and containing the soluble sodium compound of antimony and sulfur and the insoluble calcium compound of arsenic and oxygen as well as a water-insoluble sulfur compound of copper is leached with an aqueous liquid, ordinarily water, to dissolve substantially only the soluble sodium compound of antimony and sulfur.  The aqueous leach solution containing the soluble sodium compound of antimony and sulfur is separated from an insoluble leach residue containing the insoluble calcium compound of arsenic and oxygen and the insoluble sulfur compound of copper.

Abstract: ABSTRACT OF DISCLOSURE          The power output from a nuclear power plant or fossil fuel power plant operating under constant reactor (or furnace) and boiler conditions is varied by regulating the rate of turbine extraction steam and primary high pressure steam used to heat boiler feed water (BFW).  During periods of low power demand excess extraction steam is drawn off to heat excess quantities of boiler feed water.  One portion of the BFW is fed to the boiler while the other portion is used to reheat a low vapor pressure (LVP) organic material preferably a hydrocarbon oil derived from petroleum, which hot material is stored under an inert atmosphere at atmospheric pressure in a high temperature storage location means.  Hot water as such, is also optionally stored, in hot storage means which hot water has either previously heated the LVP organic material or which hot water has itself been only slightly heated with low pressure extraction steam as BFW. Such stored hot water, at a temperature of 210°F. during periods of high power demand, is itself used as boiler feed water and is heated by a moving stream of hot LVP organic material moving from high temperature storage location means to low temperature storage location means and sent to the boiler.  During periods of high power demand BFW preheat duties would be taken over entirely by the moving LVP organic material, moving from hot to cold storage ocation means, use of extraction steam for BFW reheat being curtailed and such untapped extraction steam being allowed instead to expend itself fully in the turbines. The boiler at all times receives a constant amount of uniformly preheated BFW. Alternatively, or simultaneously, the stored hot LVP organic material can be used to raise intermediate pressure steam and this steam can be injectable into the steam turbines between appropriate stages or into auxiliary turbines used solely for this purpose.

Abstract: ABSTRACT                        A method of applying a porcelain enamel coating to a ferrous workplace which eliminates the necessity for pickling the surface or coating the surface with a flash nickel coating.  The ferrcus workplace is merely cleaned with conventional cleaning events and then a dry particulate coating of a reactive material is electrostatically applied thereto.  The reactive coating consists of a relatively hydrophilic, soft fritted glass which has the capability of reacting with the underlying workpiece surface at temperatures on the order of the firing temperature, and below. A second coating consisting of a porcelain enamel frit is then electroctatically applied to the previously coated workpiece. The firing of the piece caused the fusion of the soft glass under-coating to react with the underlying workpiece surface and eventually causes the porcelain enamel frit to form a continuous porcelain enamel coatingthereover.

Abstract: FRICTION CONTACT TONING MEANS                 ABSTRACT OF THE DISCLOSURE         A frictional contact toning apparatus for a magnetic imaging system is disclosed.  Magnetic toner from a reservoir is deposited on a donor surface forming the top layer of a rotating carriage cylinder.  The toner laden donor surface is brought into frictional contact with a moving image web surface having a latent magnetic image formed thereon.  The rotation of the donor surface is faster than the velocity of the image web surface and in the same direction which causes a frictional slippage between the two surfaces.  Full and even development of the latent magnetic image is produced by an excess of toner that forms at the toning nip and the scrubbing action of the rotating donor surface.

When the web is a double layer then the panels are in the form of bags, the layers being sealed at the sides of the bags at the per-forations in the zones of weakness.          A machine for making the web, causes a web of synthetic plastics material to pass longitudinally past a transverse hot cutting and welding edge which cyclicly inter-sects the web at longitudinally spaced intervals.  The hot cutting and welding edge has a series of interruptions along its length.

Abstract: WEATHERSEAL MANUFACTURE ABSTRACT OF THE DISCLOSURE           A weatherseal is made by preparing a long, thin strip of pile material and cross-head extruding a resin base having a relatively thick, generally flat support portion formed on the back of the pile strip and a relatively thin portion U-shaped in cross section and joined to opposite side edge regions of one face surface of the support portion while arching over the pile strip.          While the resin material is still plastic, a substantially lower pressure is produced outside the U-shaped portion than inside this portion to expand this portion away from the support portion and reduce the thickness of the wall of the U-shaped portion.  The resin material is set with the U-shaped portion expanded over the pile strip.  The result is one product of the invention.  As an alternative, a modified product can be obtained by cutting each side of the U-shaped portion at the approximate height of the pile from the support portion to leave a pair of thin, spaced-apart resilient fins extending away from the support portion on opposite sides of the pile strip.
