Title: Servoed linear accelerometer
Inventor: HOLDREN FREDERICK V
IPC: G01P15/08

Granted: 1980-05-27
Abstract: ABSTRACT OF THE DISCLOSURE   In order to facilitate construction of a compact, lightweight servoed accelerometer with capacitive pick-off, a one-piece support frame, adapted to be inserted within a cylindrical housing, is used to support a pair of capacitor plates and a lightweight longitudinally reinforced pendulum or seis-mic mass having a paddle on one end.  The paddle is positioned midway between the capacitor plates, thereby forming a pair of capacitors each having a capacitance on the order of 2 to 4 picofarads.  Attached to the pendulum is an axle which in turn is supported between two flexures by means of jeweled pivoted bearings.  The ends of the flexures are rigidly secured to the support frame, and a desired pressure of the bearings against the axle is maintained by means of adjustment screws.  Also attached to the pendulum is a torque coil which interacts with a magnetic assembly, secured to the support frame, to restore the paddle to the midpoint between the capacitor plates when the pendulum has been subjected to an acceleration force.  Secured to the support frame above and parallel to the pendulum is a thick film circuit board con-taining an integrated circuit and associated hybrid elements for applying time varying voltages to each capacitor so that the currents flowing through the capacitors can be used as a measure of the difference in capacitance due to deflection of the paddle; and in response thereto, generate sufficient current in the torque coil to restore the paddle to the midway point between the capacitor plates.  The circuitry also includes an output circuit having a servo-compensated network for applying a restoring current to the torque coil wherein the gain and frequency characteristics of the servo system are independ-ent of any impedance used to measure the restoring current.

Abstract: CUTTER FOR HELICALLY CORRUGATED TUBE FOR FLEXIBLE GAS INSULATED CABLE            ABSTRACT OF THE DISCLOSURE:         A cutter for a helically corrugated tube in which a pair of rings are connected by a blade carrier to form a track around the tube.  Each of the rings comprises a pair of "C" members hingedly connected at one end and releasably connectable at the other end to form the ring.  Each "C" member has a pair of rails supporting a circumferentially movable carrier having rollers at each end engaging the rails of the adjacent pair of rings.  A holder on the carrier projects outwardly between the rails.  A yoke in the holder carries the cutting blade; a compression spring in the holder drives the yoke and blade toward the tube.  A threaded cap on the holder adjusts the compression spring and also provides a handle recess.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention pertains to a pigmentable, low-shrink molding composition based on thermosetting, unsaturated polyester resin in combiantion with lightly cross-linked polymer particles. The lightly cross linked polymer particles have a particle size preferably between about 20 microns to 50 microns and can be selected from lightly cross-linked condensation polymers and lightly cross-linked addition polymers.  In a preferred aspect of the invention the lightly cross-linked polymer particles contain minor amounts of pendant reactive groups selected from amino and oxirane groups to produce a one-pack stabilized low-shrink mold-ing resin mixture.  The pigmentable low-shrink molding composi-tions are stabilized dispersions containing pigments dispersed therein in conjunction with thermosetting polyester polymer, monomer, and lightly cross-linked polymer particles as well as fillers to provide a pigmentable low-shrink molding composition which cures to uniformly pigmented low-profiled molded part.

Abstract: Abstract of the Invention A dust extraction hood is mounted for pivotal movement with its associated tool on an automatic shoe bottom roughing machine. A parallel linkage is arranged to permit the hood to be spaced equidistantly from the shoe bottom throughout the operation of the machine, or in a way in which the tool becomes retracted into the hood during upward movement thereof. The retraction can be so arranged where maximum clearance is required, that the tool can protrude from the hood, and as the clearance requirements decrease, the hood member can shroud a greater area of the operating surface of the tool.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus for automatically dispensing a mea-sured volume of liquid.  The liquid is fed into a cylinder and displaces a piston which expels quantity of liquid pro-portional to the piston stroke.  At the end of the stroke, the piston is made to abut a close a switch which actuates an electric motor driving a four-way rotary valve to reverse the liquid flow direction in the cylinder, whereby the piston moves in the opposite direction to discharge a measured amount of the liquid which was previously used to push the piston.           The piston, at the end of its second stroke, again strikes and causes the closing of a second electric switch which produces rotation of the four-way valve to again reverse the liquid flow to its original direction.  The back-and-forth movement of the piston can be automatically repeated a predetermined number of times, being governed by an electric counter or any similar electri-cally-operated device.  Means are provided to prevent the formation of air pockets in the clyinder, which would affect the measuring precision.  The position of the electrical switches can be varied to vary the piston stroke and, therefore, the quantity of the liquid dispensed.  As a modification, one or more additional cylinder and piston assemblies are provided with their pistons mechanically connected to the piston of the main cylinder and arranged to dispense two or more liquids in exact proportional amounts.  Another embodiment shows a variable volume cylinder to adjust the amount of liquid being dispensed.        The four-way valve is leak-proof between the two liquid circuits because its valve member is frusto-conical and is pushed in seating position by a by-pass of the liquid under pressure.  The apparatus can measure with great precision liquids of various viscosities and under very low or very high pressure.

Abstract: ABSTRACT This disclosure relates to an electrically-actuated door holder and release for the multi-point holding of a pivoted door at selected door opening angles, and for the release of a held door either electrically or in response to manual override.  The door holder and release includes a rotatable spindle adapted to be connected to a pivoted door which is either push or pull-side mounted.  The holder and release comprises a spindle gear assembly having a pair of male spline gears with each gear having a circu-lar ring of splineways forming a series of male projecting keys. A pair of cams, each having cam lobes defining detent segments with each cam having a circular hole internally grooved to mate with the projecting keys of spline gear, is mounted on the shaft. A pair of springs yieldingly hold the cam into mating positions with associated spline gears to rotate therewith.  A double lever having a common pivot or fulcrum carries a roller which follows the cams.  The lever may be electromagnetically actuated and re-leased to effect a door hold and release, or alternatively, the lever maybe manually overridden.  The selected hold-open angles may be set and altered, without removal of the holder and release or the associated door closer from their fixed positions on a header frame and door, respectively.  This function is attained by the arrangement of the cams on the spline gears in association with depressible springs which enable the cams to be manually adjusted without removal of any component except the housing cover.

Abstract: ABSTRACT           A spring cushioned static seal hydraulically operated actuator is disclosed which contains a hydraulically driven piston arranged to reciprocate in a chamber.  A spring couples the piston to a rotatable shaft which limits the torque placed on the shaft by the piston in its drive stroke.  A return spring functions to return the piston and drive spring to their initial positions upon release of the hydraulic drive applied to the piston.  A static seal on the piston seals at the completion of the drive stroke of the piston.  The actuator may be used to operate a subsea diverter to direct "pump down" or through flow line (TFL tools) through wye-branched flow passageways formed in a diverter body member located on a submerged well head.
