Title: Method of logging an inclined wellbore
Inventor: WINTERS WARREN J
IPC: E21B47/00
Filed: 1988-09-01
Granted: 1992-01-21
Abstract: ABSTRACT OF THE DISCLOSURE         A method is disclosed for logging a formation penetrated by an inclined or horizontal wellbore utilizing a conventional logging tool.  A collar catcher assembly is attached to a lower portion of a drillstring and a collar is attached to an upper portion of a logging tool.  The drillstring is lowered within the wellbore to a position adjacent the formation to be logged.  The logging tool is transported through the drillstring until the collar ther-eon engages and is restrained by the catcher assembly.          Then the formation is logged while the drillstring is withdrawn through the wellbore.

Abstract: Abstract of the Disclosure A jack module with a lamp assembly that is intercon-nected at the top front of a printed circuit board and has a bottom guide channel for slidably receiving a tri-jack.  The printed circuit board has top and bottom forwardly extending necks which define a notch therebetween.  The lamp assembly has a lamp housing with a hollow trunk and two legs that provide upwardly and downwardly facing channels that slide onto the bottom and top edges of the top neck.  The housing, which has a longitudinal bore holding a lamp, encases conduc-tive strips which engage the lamp.  The housing is locked to the neck by a retainer that has a boss that snaps into an aperture in the housing.  A guide housing is similarly con-nected to the bottom neck.  The lamp housing and bottom guide housing have facing guide channels which respectively receive top and bottom guide rails of the tri-jack in slidable engage-ment back to a printed circuit board connector in the notch.

Title: High frequency vlsi oscillator
Inventor: EMBREE DAVID M
IPC: H03B5/36
Filed: 1988-11-25
Granted: 1992-12-22
Abstract: HIGH FREQUENCY VLSI OSCILLATOR Abstract Maximum frequency range in a VLSI voltage-controllable crystal oscillator is obtained with a two-stage amplifier with feedback across both stages. The first stage is implemented by an MOS transistor connected in source-followerconfiguration to minimize input capacitance, and the second stage provides the needed gain. If the second stage is implemented by a CMOS transistor, its source electrode and body are connected together to eliminate body effect. A bidirectional voltage limiter connected to a crystal node limits the oscillations to a symmetrical waveform. The bias of an output buffer amplifier may be selectively shifted to maintain optimum duty cycle with the different triggering levels of diverse logic driven by the oscillator, and the bias may be dynamically driven by an analog signal to provide a duty cycle-modulated output.

Granted: 1993-03-23
Abstract: ABSTRACT         A low voltage drop, high current electrical connector which can be releasably mated with associated contacts is disclosed.  The connector makes use of elongate contact arms cantilevered in a housing.  Each contact arm is made up of at least two superposed beams one of which has relatively high electrical conductivity but relatively poor mechanical spring characteristics.  The other has relatively low electrical conductivity but relatively good mechanical spring characteristics.  In this way the mechanical and electrical characteristics such as contact force and conductivity may be controlled, balanced and optimized.  As one possibility there could be a single spring steel beam backing a stack of sheets of high conductivity copper.  As another possibility, there could be sheets of high conductivity copper alternating in a stack with sheets of copper spring which is about half as conductive as pure copper.  Instead of a cantilevered spring a coil spring located at the contact surface could be used.

Granted: 1993-10-12
Abstract: FOAM INSULATED VESSEL AND METHOD OF MAKING THE SAME Abstract of the Disclosure A foam insulated vessel, such as a water heater.  The water heater includes a tank to contain water to be heated and a jacket is spaced outwardly of the tank to provide an annular cavity therebetween.  An annular flexible strip is secured to the surface of one of said members, and is in sealing relation with the other of said members, thus forming a closure or dam at the lower end of the cavity.  In a preferred form, the strip includes a flange secured to the tank and a body portion extends outwardly from the flange and termin-ates in a downwardly extending lip, which is located at an acute angle with respect to the body portion.  The lip is in sealing engagement with the jacket.  When a liquid foamable resin is introduced into the upper end of the cavity, the pressure acts to force the body portion of the seal downwardly, increasing the sealing effect against the jacket to retain the liquid resin within the cavity.

Granted: 1992-07-21
Abstract: Abstract of the Disclosure A phase detection circuit for detecting the phase shift of an input signal.  An A/D converter converts the input signal into first, second and third digital data according to successive three sampling points.  A first subtracter subtracts the third data from the second data to produce a first subtraction signal.  A second subtracter subtracts the first data from the second data to produce a second subtraction signal. A third subtracter subtracts the second subtraction signal from the first subtraction signal to produce a signal representing the phase shift.  An adder adds the first and second subtraction signals together to produce a signal representing the amplitude of the input signal.          A converter converts the signal representing the phase shift into a signal representing the absolute value of the phase shift according to the signals representing the phase shift and the amplitude.

Abstract: Abstract A method of controlling, during the act of mold fabrication in real time, the compactability and permeability of a sand mold containing an evaporative foam pattern, comprising: (a) while agitating a supply of loose, unbonded sand introduced about such pattern suspended in a flask, supplying a pressurized gas to one station of the sand while permitting the gas to exit from another station of such sand supply; and (b) proportionally measuring the pressure differential between such stations thereby rendering a proportional indicator of sand compaction.  Agitation is preferably carried out in stages, the first stage of which comprises agitation by vibration at a rate to migrate the loose sand grains into the interior voids of the pattern, and a second stage in which the vibration is carried out at a rate until the relationship P2 = kP1 is satisfied, where P1 is supply pressure, P2 is back pressure where the gas pressure attempts to migrate through the sand, and where k is a factor dependent on sand chemistry, shape, and moisture and is always less than one.

Abstract: Burner for a suspension of fine-grained coal in a liquid, particularly water, which burner operates according to a combination of the rotary burner and toroidal burner principles. The fuel is supplied axially behind a transverse distribution baffle (12,31, 55,65) within a conical rotary body (10, 30, 50,60). At least the outer rim portion (13,62) of the inner side of the rotary body (10, 30, 50, 60) forms an angle of35-80° with the axis of the burner. At the outer edge (13, 45, 64) of the rotary body there is an annular air supply nozzle (16, 46, 70) for supplying a conically diverging outwardly directed air stream (17,47). Outside the air supply nozzle and at a radial distance from it, there is a conical guide baffle (18,48) which at its outer end may be curved inwardly (at 22, 48') and which, together with the diverging air stream, serves to produce a positive recirculation of combustion gases, non-combusted coal particles and ash particles in a direction back towards the rotary body in accordance with the toroidal burner principle.
