Title: Fluid coupling and method of making same
Inventor: PAUL VERNON JR
IPC: F16L37/14
Filed: 1983-01-28
Granted: 1985-09-17
Abstract: ABSTRACT OF THE DISCLOSURE An improvement is provided in a fluid coupling for a conduit which features a quick connect-disconnect construction between first and second coupling members.  The coupling includes first and second coupling members and retaining means for interlocking the members, the first coupling member having a generally cylindrical configuration comprising a main body portion, a reduced diameter body portion having a peripheral surface, and a first wall extending radially of and intersecting the  portions, the main body portion having a peripheral groove therein, the second coupling member being positioned over the first coupling member and having a principal cylindrical bore generally contiguous with the reduced diameter portion, an enlarged diameter bore generally contiguous with the main body portion, and a second wall contiguous with the first wall and extending radially of and intersecting the bores, the intersection of the second wall and the principal bore forming a beveled shoulder, the enlarged diameter bore having a peripheral groove opposite the peripheral groove in the first coupling member, the retaining means comprising a U-shaped member having legs, the legs being inserted into the peripheral grooves of the first and second coupling members to interlock the members, the reduced diameter body portion of the first coupling member having a plurality of spaced peripheral grooves therein, and resilient sealing members positioned with the grooves and contacting the second coupling member to create a fluid-tight seal. The improvement resides in the fact that one of the peripheral grooves is located at the intersection of the first wall and the reduced diameter body portion and interrupts the peripheral surface immediately adjacent the first wall, the bevelled shoulder being located radially contiguous to the one peripheral groove and engaging and compressing the sealing member in the one groove in such a Abstract continued manner that the sealing member in the one groove is placed under compression andapplies axial and radial compressive forces between the first and second coupling members.  This avoids the dual problem of shock load resulting in fatigue and failure,  and low pressure weepage past the sealing members.

Abstract: ABSTRACT The invention relates to apparatus for analyzing electrical circuit boards.  Individual elements which have failed can be identified without dis-connecting them from the circuit and testing may be done by unskilled operators by contacting a probe to a lead on an element.  The probe has at least two contact elements close enough to each other to simultaneously contact a lead of a mounted integrated circuit, but spaced apart from each other sufficiently to permit measurement of electrical activity in the lead segment between the tips.  Circuitry is connected to the probe for measuring the voltage drop between the two tips resulting from the flow of test current through the resis-tance of the lead segment, which current flow is indicative of the condition of the element.

Abstract: APPARATUS FOR SEPARATING                PARTICULATE MATERIALS          Abstract Particles having different properties (e.g. part-iculate fly ash and carbon)  are separated by moving the particles forwards along a horizontal, gas-permeable electrode plate (1) above which is mounted a second electrode (2) having at least one plate (4) mounted at an acute angle (?)  to the horizontal.  Preferably, two plates (4) each extend sideways from a central block (3) of dielectric material.  The particles are fluidized, continuously or intermittently, by a gas stream passed upwards through the plate (1), which may be of sintered metal.  An alternating electric field is generated between the electrodes (1, 2) by a high voltage AC power source (14).  The field lines (16) from each plate (4) curve to the side and impart centrifugal forces to part-icles charged by friction or conductive induction, which forces separate the lighter, more highly charged particles from the others.  The particles may be moved by means of a vibratory transducer (12).  Alternatively, the gas-permeable plate may slope downwards in the forward direction allowing the fluidized particles to move in that direction under the force of gravity.  The separated particles are collected in bins (13) arranged around the lower electrode (1).

Abstract: ABSTRACT OF THE DISCLOSURE     A shape of a wall surface of a direction changing path of a roller bearing for an endless linear motion. The outer wall surfaces of the direction changing path are formed convex outward.  This convex outward outer wall surface can be formed as a spherical band with its center of curvature lying on the axis of revolution of the direction changing path.  such outer wall shape allows a minimum play of the rollers of the roller bearing for an endless linear motion during the direction changing motion through the direction changing path.  As a result, stick-slip motion as well as the resistance of the rollers during the direction changing motion are reduced.  Accordingly, the total the resistance of the roller bearing for an endless linear motion is reduced, producing an improved roller bearing for an endless linear motion as a whole.

Abstract: SPEED REDUCING CONTROL SYSTEM WITH VOLTAGE REGULATION FOR A POLYPHASE ELECTRIC MOTOR A variable speed 3-phase a-c motor is connected via a plurality of controllable bidirectional switches to a 3-phase source of alternating voltage having a variable fundamental frequency (f) and an rums magnitude (v) that varies with f, and the switches are suitably arranged and controlled so that motor speed can be reduced by skipping selected cycles of the source voltage. When operating at a fraction of full speed, the magnitude-to-frequency ratio of motor voltage is maintained substantially the same as at full speed by varying the "firing angle" at which the switches start conducting current so as to minimize any deviation in the rms magnitude of the motor voltage from the product of v times said fraction.
