Title: Artificial pumice stone
Inventor: PIETSCH TIBOR
IPC: C04B32/00
Filed: 1988-07-19
Granted: 1995-05-30
Abstract: Artificial pumice is produced which comprises cellular glass bodies devoid of glass crust and with rounded edges and points, and preferably having a density between about 0.2-2.0 grams per cubic centimeter and preferably having maximum size of between about 1-30 centimeters.  These glass particles are relatively lightweight and are abrasive, which regular and regulatable density, mechanical strength, cell size, and an abrasivity. Particles of waste glass (e.g. of a size up to about 1 millimeter) or vitrifiable material, are mixed with a cellulating agent such as calcium carbonate.  The mixture is heated, as by disposing it on an endless refractory belt which continuously passes through a kiln at a temperature of about 700°C or greater, to melt the particles, and to produce relatively small or large cellular glass bodies.  The size of the large cellular glass bodies can be reduced to small bodies by sudden temperature change (e.g. quick cooling at a rate of between about 100-400°C per minute), or by mechanical action.  The desired small cellular glass bodies can also be obtained by dosing the corresponding independent small portions of the mixture before the kiln process.  The smaller bodies are then placed in a rotary cylinder and brought into abrasive contact with each other to remove any glass crust, dirt, etc. and round edges and points.

Title: Subsurface well safety valve
Inventor: CARMODY MICHAEL A
IPC: E21B34/00
Filed: 1988-08-24
Granted: 1992-03-10
Abstract: ABSTRACT OF THE DISCLOSURE     In a safety valve having an axially shiftable actuating sleeve operable to move a valve head from a closed to an open position, the actuating movement of the actuating sleeve is normally produced by a small diameter piston mounted on an axially extending spindle secured to the valve housing and cooperating with a primary cylinder which is abuttingly secured to the actuating sleeve.  A secondary spindle and cooperating cylinder are provided which are supplied with fluid pressure by an entirely separate line extending to the well surface.  The second cylinder has only abutting contact with the actuating sleeve and may be utilized to effect the movement of the actuating sleeve in the event of the failure of the primary cylinder.  In a modification, a fixed cylinder housing defines a pair of secondary cylinder bores in which secondary rod pistons are slidably mounted to effect the movement of the actuating sleeve.  In both modifications, collet latches prevent return movement of the secondary cylinder or secondary rod pistons, thus locking the valve head in an open position.

Abstract: An ornamental heat transfer is described which is especially adapted for application to nylon fabrics.  The ornamental heat activated transfer includes an upper layer which is generally a thermoset layer, cloth such as twill or flock which is bonded to a lower layer.  The lower layer is an uncured linear saturated polyester film which includes a heat activatable isocyanate curing agent.  Upon application of the transfer to nylon the transfer is heated which melts the uncured saturated polyester and activates the curing agent.  Thus while the linear saturated alkyl polyester is in a molten state the curing agent causes the polyester to cure in tight confinement with the nylon fabric.

Title: Electrical storage cell life extender

Granted: 1993-07-06
Abstract: ABSTRACT OF THE DISCLOSURE         The useful life of an electrolytic battery cell commonly employed in a series string as a backup power source is significantly extended by maintaining the polarization of the positive plates of such a cell at a predetermined level relative to a reference electrode of similar composition in contact with the cell electrolyte. While the cell is being supplied with the usual float charging voltage, a controller circuit senses any variance of polarization below the desired level and meters a minute input current to the positive plates with a resulting increase in the polarization over a substantial time period.  The slow biasing of the polarization effects a passivation of the surface of the plates which deters the penetration of oxygen to the plate metal and prevents the deep destructive formation of expansive metal oxide.

Abstract: ABSTRACT OF THE DISCLOSURE        A hydraulic control valve for controlling the parking brakes of a vehicle hydraulic braking system having mechanically applied parking brakes which are released by hydraulic pressure includes a housing having a mechanically actuated control valve and a diverter assembly.  When the vehicle is parked, the parking brakes are vented to reservoir and fluid from the vehicle hydraulic pump is communicated directly from the inlet of the valve to the return or drain port of the valve.  When the brakes are released, communication between the spring brakes and reservoir pressure is cut off, and fluid communicated into the inlet is diverted to the diverter assembly, which builds pressure to a predetermined level which is communicated to the vehicle parking brakes to release the latter.  When the predetermined pressure level is attained, the diverter assembly automatically opens to permit fluid to bypass the diverter assembly back to the return or drain port.

Abstract: Gas analyzers of the non-dispersive infrared radiation type which are designed to measure the concentration of one gas in a mixture of gases containing that gas.  A novel, electrically modulated, stable, thick film infrared radiation emitter is employed to emit a beam of collimated, focused energy; and two electrically biased detectors are preferably used so that a ratioed, error eliminating output signal can be supplied to the failsafe, signal processing circuitry of the analyzer.  The latter, and a conventional analog-to-digital convertor, supply information to a microcomputer which:  (1) turns the infrared radiation emitter on and off; (2) controls a heater which keeps the infrared radiation detectors at a constant, precise temperature; and (3) controls displays of a variety of information concerning the gas being measured and the status of the gas analyzer.  The microcomputer also accepts ambient temperature, barometric pressure, and other compensation factors. Typically, a disposable airway adapter will be included in the gas analyzer to confine the mixture of gases being analyzed to a path having a transverse dimension of precise and specific length and to provide an optical path across that stream of gases between the infrared radiation emitter and the infrared radiation detectors. The emitter and detectors are incorporated in a transducer head which can be detachably fixed to the airway adapter.
