Abstract: APPLICATION OF                  ANTHONY D'ONOFRIO           A.C. POWER CONTROL FOR                D.C. SOLENOID ACTUATORS               ABSTRACT   An A.C. power control circuit for a D.C. solenoid actuator which may be used for a solenoid operated valve uses a triac circuit to initially apply A.C. line voltage to energize the solenoid coil of the valve to be actuated to provide valve pull-in power.  A capacitor in an RC network is concurrently charged to a D.C. level, and the D.C. voltage on the capacitor is used to control the gate of the triac.  After a predetermined delay as determined by the RC network charging time of the capacitor, the triac is phase controlled to produce a change in the current applied to the solenoid coil.  In one embodiment, the voltage applied to the solenoid coil changes at this time from the full sine wave voltage of the A.C. source to a voltage pulse which is only a portion of the positive half of the input sine wave.  This voltage produces a change in the power applied to the solenoid coil to a hold-in power level.  This circuit produces a current pulse phase control of up to 90°.  In a second embodiment, a phase control of up to 180° can be achieved by using a full wave bridge circuit for rectifying the A.C. to supply D.C. power to a timing circuit operating in the base circuit of a transistor controlling the energization of a photo triac. The output of the photo-triac is, in turn, used to control the "on" time of the power triac supplying the current to the solenoid coil.

Title: Two-part wheel bracket assembly and a method of  making it
IPC: B60B33/00

Granted: 1988-01-26
Abstract: TWO PART WHEEL BRACKET ASSEMBLY    AND A METHOD OF MAKING IT              ABSTRACT OF THE DISCLOSURE A wheel bracket assembly includes two separate, platelike bracket parts which each have a noncircular opening therein and are disposed on opposite sides of a wheel in angular alignment.  The ends of the axle for the wheel extend through the noncircular openings and the bracket parts are fixed against axial and rotational movement with respect to the axle.  A method of making the wheel bracket assembly includes the steps of stamp-ing out from at least one metal plate the two bracket parts which are substantially mirror images of each other and have the noncircular opening therethrough, placing the bracket parts in angular alignment on opposite sides of the wheel so that the ends of the axle extend through the noncircular openings, and upsetting each end of the axle to retain the bracket parts in place and so that the material of the axle flows to fill the noncircular openings in the bracket parts and thereby prevent relative rotation of the bracket parts.

Abstract: Abstract of the Invention The Hall element consists of a substrate (6), of a semiconductor layer (5), of a surface layer (22), of an insulation layer (19), of contact diffusions (7 to 12), of insulation rings (16;17, 17; 18) which are all made of P or N semiconductor material.  The Hall element which has two sensor terminals (..., S2), is subdivided by at least one plane of section into arrangements (2, 3) which are alternately turned upside down or not turned around and are located within the semiconductor layer (5).  Between at least two points of each upper and lower surface of the arrangements (2,3) and one of the equipotential points of an adjoining arrangement are electric connections (a2, b2, c2, d2), whereby each of he points of the outermost surfaces of the current terminals (C1, C2) of the Hall element by means of connections (a1; b1; c1; d1, 20 or a3; b3; c3; d3, 21).  These connections and the contact diffusions (7 to 12) are made of N+ material. This construction of the Hall element makes it possible to realize very large Hall elements which can be used in electricity meters, for example, to measure a magnetic field (H) produced by an electric current.

Abstract: SLIP CONNECTOR FOR WEIGHT ACTUATED HEIGHT ADJUSTORS                 ABSTRACT OF THE DISCLOSURE          A slip connector is provided for swivel chairs, and other similar seating, of the type having a base, a seat rotatably supported thereon, and a weight actuated height adjustor, which engages when the seat is unoccupied to facilitate adjusting the seat height, and disengages when the seat is occupied to permit the seat to swivel on the base without affecting the seat height.  The slip connector includes two coupling members, which rotate about a common axis when the seat swivels about the base.  A stop mechanism positively interconnects the coupling members causing them to rotate together when they assume a first, angular relationship.  A spring interconnects the coupling members, and biases the same when the. seat is unoccupied into a second angular relationship, which is spaced a preselected angular measure from the first angular relationship, such that when the user exits the seat, the seat must be rotated through the preselected angular measure before the seat height can be adjusted, thereby greatly alleviating any unintentional height adjustment.

Abstract: TEST POINT ADAPTOR FOR CHIP CARRIER SOCKETS  ABSTRACT OF THE INVENTION          This arrangement provides for attaching test or probe leads for such instruments as a logic analyzer to a leaded chip carrier.  This arrangement provides for terminating each chip carrier lead to a metallic post upon which a logic probe or other test apparatus may be mechanically attached to make electrical connection.  Since leaded chip carriers have their contact leads closely spaced, this arrangement expands this distance between leads to a suitable distance for connecting test probes.  In this manner, the semiconductor chip may be functionally tested as part of a circuit on a printed wiring card.

Abstract: "OIL WELL DOWNHOLE LIQUID INJECTION ASSEMBLY"                ABSTRACT OF THE DISCLOSURE A downhole pump is actuated by a reciprocating unit comprising a tubular rod string, a valve assembly, and a tubular plunger rod.  A flow passage extends through the reciprocating unit when the valve assembly is in an "open" position, whereby liquid may be injected into the pump barrel chamber to ensure the presence of incompressible fluid in the chamber from the beginning of the up stroke, to thereby reduce or eliminate gas locking of the pump.  The valve assembly, which moves together with the reciprocating unit of which it is part, is adapted to interact with a stop member on the stationary pump barrel, to initiate opening of the valve as the rod string approaches the bottom of its stroke.  The valve assembly is further adapted to automatically close when lifted away from the stop shortly after the beginning of the up stroke.  The valve thus remains open only during the bottoming out phase of the stroke, when only limited travel of the reciprocating unit occurs.  The valve assembly is adapted to accommodate this limited travel while remaining open.

Abstract: Needle jacks on the roataing cylinder of a multifeed machine are selected by electromagnets of which there is one for each feed. Pattern control, effected by selective energisation of the electromagnets, is governed by a set of photo-diodes, one for each feed, between each of which and a light source runs a programme tape having a track for each diode consisting of transparent and opaque areas in predetermined sequence. Synchronisation of control pulses from the ligh-energised diodes with rotation of the cylinder is such that electromagnets on a multi-section cam box are selectively energised precisely when a passing jack is opposite and electromagnet.

Abstract: In a method and in an apparatus for measuring the volume V of a gas in a container 20, the volume of the container is varied following a sine wave with a minimum value and a maximum value. The volume of the container is varied at a constant frequency and a varying amplitude to achieve a predetermined pressure difference δp, and the corresponding volume difference δV is determined by detecting the times at which at least two points on the sine wave are achieved which correspond to two predetermined values for the volume of the container. By measuring the interval between the two points on the sine wave, the peak values of the latter for the volume difference δV corresponding to the predetermined pressure difference δp, and thus the volume difference δV also, can be calculated. By means of the formula V = δVxp0xM/#dp, where p0 = the static pressure and M = Cp/Cv, where Cp and Cv are the specific thermal capacity at, respectively, constant pressure and constant volume for the gas in the container, the gas volume V in the container can be determined. An apparatus for implementing the method is also described. <IMAGE>
