Abstract: ONCE THROUGH SLIDING PRESSURE STEAM GENERATOR            Abstract of the Disclosure A once through steam generator (10) for sliding pressure operation from supercritical pressure at high loads into the sub-critical range at low loads, having vertical tubes (14) lining the furnace (12) walls and passing their entire length without a mixing header.  The furnace tubes are internally rifled and have orifices (47) associated with them to proportion the flow at full load.  A steam separator (26) receiving effluent from the tubes sends steam to the superheater (70) and at low ratings returns water (32,40) to the tubes for recirculation therethrough.  The tubes (14) are sized in accordance with a specified criteria based on the mass flow rate at full load, or on the ratio of friction drop to static head.

Abstract: WOOD BURNER                    Abstract of the Disclosure Apparatus for burning combustible particles to heat circulated air.  The apparatus includes an upright housing containing a removable liner which forms the combustion chamber of the burner, and a perforated, intermediate wall member which forms, with the walls of the housing and the liner, outer and inner gas-receiving spaces, respectively.  Air injected into the housing passes from the outer, into the inner gas-receiving space, where the gas is directed, through tuyeres in the liner, into the chamber, substantially tangentially to the wall thereof, producing a gas vortex therein.  Particles introduced into the chamber through an upper opening are combusted primarily in the chamber's upper core region with such combustion being supported by, and acting to heat, vortexing gas within the chamber prior to its discharge through a lower chamber opening.

Abstract: MULTIPLE INJECTOR FLOW THROUGH DISSOLUTION CELL FOR DISSOLUTION TESTING APPARATUS            Abstract A dissolution cell for use in automatic dis-solution testing apparatus is specially configured to accommodate the iterative insertion of product specimens into the dissolution mechanism flow stream, and to perform the specimen insertion into a stabilized flow stream with minimal insertion disturbance.  A basic multiple-injection embodiment utilizes a linear configuration to selectively insert two specimens into the flow stream, and a circular multiple-injection embodiment teaches the selective insertion of a plurality of specimens into the stream in a manner amenable to a program-mable sequence.  Both embodiments use air evacu-ation of the specimen flow chamber prior to its insertion into the instrumented flow stream, and both allow a high degree of fidelity in the dis-solution measurements performed.  The improved cell is especially useful for testing rapidly dis-solving industrial products or drug dosage forms.

Abstract: Summary In a contactless keyboard including for each key a transformer (1) with a core (7) displaceable by the key operation and including a com-pensation transformer (2) common to all keys the compensation transformer is so designed that with an unactuated key the signal component of the compensation transformer in the signal applied to the evaluation circuit exceeds the component of the key transformer, whereas with an actuated key the signal component of the key transformer predominates.  Therefrom results a phase change of the signal applied to the evaluation circuit with the actuation  of a key.  The evaluation circuit compares the phase of the key output signal with that of a reference signal.  For increasing the immunity from disturbance the evaluation circuit delivers an output signal (key operated or key nonoperated) only when several successive comparison operations give the same result.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to an improved valve pin for an injection molding system and a method of making the same.          The elongated valve pin has a tip end portion which extends from a larger driven end portion into the flow of melt to the cavity.          The elongated tip end portion is provided with a desired combin-ation of strength and thermal conductivity by having a copper core inside a steel casing.  The casing is made by brazing a tip end cap member to a hollow sleeve.  A predetermined quantity of copper wire is then inserted into the casing and melted in a vacuum furnace to form an integral construction.  The excess sleeve is then cut off and the end is brazed into a well in the driven end portion of the valve pin.  The tip end cap member is then machined to provide a tip end of a desired shape.         Filling the copper into the steel casing in a vacuum furnace bonds them together without any insulative spaces, thereby relatively inexpensively providing a valve pin structure which has the necessary structural strength to withstand repeated closing forces, while at the same time providing for the improved transfer of heat along the valve pin to the gate area.

The impedance level of the transfer network is adjustable and is compensated for by the amplifier.  A high impedance level allows for small element values for certain components such as capacitors so that a wide frequency band driving point impedance may be realized with integrated circuits.  Further decrease in capacitor values is achieved utilizing capacitor magnification.  The driving point impedance may be realized in balanced or unbalanced-to-ground fashion.

Abstract: ABSTRACT          A hydraulic system (40) for an excavator (10) which utiilizes regeneration, minimizes cavitation, and provides hose break protection is disclosed.  A valve assembly (50) is permanently connected to a hydraulic actuator (30) which is to be controlled.  A hydraulic power supply (42) remote from the hydraulic actuator is connected to the valve assembly (50) through a pair of flexible hoses (56, 58).  Pressurized hydraulic fluid can flow to the valve assembly through either of the flexible hydraulic hoses, but the valve assembly (50) includes a check valve (60) so hydraulic fluid return is only possible through one hose (56).  A two position valve (62) is provided in the valve assembly (50) between a pair of operating ports (36, 38) on the hydraulic actuator (30).  The two position valve (62) can be opened in response to a signal from the operator, connecting the two ports (36, 38) together to permit regeneration. The valve assembly (50) also includes a pressure relief valve (64) connected to one of the ports (38) to limit overpressure.  A second check valve (66) is connected around the pressure relief valve (64) to permit hydraulic fluid to flow from a reservoir (43) to the hydraulic actuator (30).  The reservoir (43) is pressurized at a relatively low pressure, so when the pressure at the associated port (38) drops below the reservoir pressure hydraulic fluid flows through the second check valve (66) to the port (38) and minimizes cavitation.

Abstract: ABSTRACT           The invention relates to improved methods of proving the calibration of meters, such as oil and water meters used in measuring fluid output of a producing oil well prior to the fluid reaching a stock tank.  The method generally involves connecting a prover vessel, having an accurate volume reading sight glass, downstream of the meter to be tested, introducing a first volume of fluid into the prover vessel, degassing the fluid and pressur-izing the vessel so as to establish a baseline reading.  A pre-selected volume of fluid as registered by the meter is then intro-duced into the vessel, degassing and pressurizing are repeated and a second volume reading is obtained.  The volume represented by the difference between the second and first volumes read at the prover vessel is divided by the volume registered by the meter to obtain a factor by which a meter reading may be multiplied to derive the true volume of fluid passing thereby.  The volumes re-corded may be temperature corrected to 15°C before the dividing step.  The prover vessel may be portable so that it can be taken from well to well by a prover crew.
