Patent CA-1288763-C (CA)
Title: Compensator for earth boring bits
Inventor: GALLE EDWARD M
IPC: F16N7/30
Filed: 1987-07-16
Granted: 1991-09-10
Abstract: ABSTRACT OF THE DISCLOSURE     In an earth boring bit of the type having a rotatable cone secured to a bearing shaft, an improved pressure compensating and relief system. A flexible diaphragm has an enlarge peripheral portion in an o-ring configuration sealingly secured in a compensator cavity to form a mud region and a lubricant region. A central portion of the diaphragm has a perforated and ridged protrusion extending into the mud region to form a self energizing area, exposed to the mud region, that seals the perforation when the pressure of the lubricant is less than or substantially equal that of the mud. A wall at the end of the compensator cavity surrounds the mud passage and engages an area around the protrusion when the diaphragm is fully extended by lubricant pressure build-up that exceeds the hydrostatic pressure. Thus, the resulting pressure differential opens the perforation, releases lubricant and relieves the build-up of lubricant pressure. However, the configuration of the protrusion is such as to prevent the entrance of mud into the lubricant reservoir since the exterior area of the protrusion exceeds that of the interior area. The differential pressure to open the perforation is selected to be not less than about fifty psi and the preferred form of the protrusion is substantially cylindrical, its perforation and lubricant entrance being beveled. An absence of metal bonded to the diaphragm helps avoid failures due to stress induce separations and debonding due to chemical attack. Clearances are used between the diaphragm and the end of the cavity and the end of the protector cup to provide self centering with the lubricant and drilling mud passages.

Granted: 1992-11-24
Abstract: ABSTRACT OF THE DISCLOSURE      An assembly for separating, metering and delivering fluids includes a central rotating member rotatable about a fixed spin axis.  A processing chamber holding member is connected to the central rotating member by a centrifugally actuated frame. At rotational speeds below a first predetermined speed, the centrifugally actuated frame is in a first position.  At rotational speeds greater than the first speed, centrifugal force moves the frame to a second position angularly spaced from and at greater distance from the spin axis than the first position.  A processing chamber is mounted on the holding member and its orientation relative to the spin axis is the same in the first and second positions.  Fluid is provided in the processing chamber.  By accelerating the processing chamber to the first predetermined speed and decelerating below the first predetermined speed in a selected sequence, specific centrifugal force vectors are generated in the processing chamber that move the fluid and retain it in selected chambers.  During this sequence, the fluid is metered, separated and delivered to a reduction area where measuring is performed.           MILV:003/C3

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to compositions of a new selective medium, designated MBL for the rapid enumeration of lactobacilli species within 24-48 hours.  This medium is effective in recovering lactobacilli from the studies of pure cultures and from a variety of foods.  Compared with the other selective media available in the market, it is far superior in growing lactobacilli while  inhibiting the  growth of StrepLococci and Entero-bacteriaceae/Aeromonas species.   The superior growth of L.  acidophilus (oral), L. salivarius (oral), L. fructovorans (vegetables), L. viridescans (meats), L. bulgaricus (dairy), L. casei (dairy) and L. delbrueckii (dairy) compared with the other selective media particularly suggested a possible universal medium for the selective cultivation of all lactobacilli.  The capacity of this medium for good growth of lactobacilli species and for the selective inhibition of non-lactics, is due to the incorporation of various growth factors and specific antibacterial agents or the selective agents.

Title: Controlled impedance connector assembly
Inventor: LAZAR MICHAEL
IPC: H01R12/50
Filed: 1989-04-21
Granted: 1992-03-31
Abstract: ABSTRACT           A connector assembly enables a dense grouping of contacts to be joined in one step to a printed circuit board (PCB) while assuring that impedances are matched among all components.  A receptacle intended for mounting on the PCB matingly receives a plug which carries terminal contacts of multiple coaxial cable leads.  The plug includes a honeycomb grounding block to engageably receive the outer conductor of each coaxial terminal, an inner conductive sleeve being electrically coupled to a signal lead by a first contact.          Signal pin contacts within the receptacle and electrically coupled with the PCB are electrically coupled with each inner conductive sleeve when the plug is inserted into the receptacle.  Likewise, ground pin contacts within the receptacle and electrically coupled with the PCB have second and third spaced resilient contacts, respectively, engaging the grounding block at distances farther from the nearer to the PCB than the first contacts.  As the plug moves toward engagement with the receptacle, the ground pin contacts first move into engagement with the grounding block to initially discharge static electricity.  Thereupon, the signal pin contacts engage associated inner sleeves of the coaxial terminals.  In its final position within the receptacle, the ground pin contacts engage the grounding block nearer the PCB than the location of engagement between the signal pin contacts and their associated inner sleeves thereby minimizing the possibility of ground loops.

Granted: 1994-02-01
Abstract: ABSTRACT OF THE DISCLOSURE    A structural magnetic vibration controller and a method for actively controlling vibrations through the use of a magnetic coupling between a damper mass and a stationary component of rotary machinery wherein the stiffness and damping characteristics of the magnetic coupling are controlled as a function of the relative movements between a first electromagnet carried by the machinery and a second electromagnet carried by the damping mass.   The magnetic  fields of the magnetic coupling formed by counterpoised electromagnets are controlled by electronic current control circuitry to achieve dynamic tuning via stiffness and dampening characteristics of the magnetic coupling so as to suppress system resonances which occur during transient machinery operation as well  as  during steady  state operation on the basis of a signal from position transducers that provides a displacement feedback that is utilized to vary the coupling stiffness, and a first derivative which is used to control the dampening characteristic of the coupling as a function of the rate at which the position sensed changes with respect to time.

Abstract: Apparatus for analyzing the composition of metal particles.  The apparatus includes a cup which, when filled to maximum capacity will hold substantially the same amount of metal particles each time it is filled, and has a profile that diverts any excess particles away from the cup.  A vessel is provided for receiving the particles from the cup and for dissolving the particles when a solvent is sent to the vessel.  A known amount of solvent is directed to the vessel to dissolve the particles and thereby provide a dissolved sample of metal for analysis.  An optical emissions spectrometer receives the dissolved sample and is employed to produce emission spectra from the dissolved sample.  The spectra is compared to emission spectra produced by a known amount of a known alloy of the same metal as the sample metal to determine the composition of the sample metal.
