Title: Axial borehole televiewer
Inventor: CLERKE EDWARD A
IPC: E21B47/00
Filed: 1986-12-08
Granted: 1991-03-05
Abstract: ABSTRACT         A borehole televiewer scans forwardly to produce images of objects longitudinally ahead of the televiewer.  It includes a housing moveable longitudinally within a borehole and an acoustical transducer mounted on the housing.  Circuit means cause the transducer to emit a sequence of acoustic pulses into the borehole and to produce signals functionally related to the acoustic pulses reflected back.  Scan means scan at least a portion of the acoustic pulses through the area of at least a portion of a transverse section of the borehole.  The signals produced by the circuit means are correlated with the corresponding transverse section scan positions of the acoustic pulses.  The transducer is orbited around the bottom of the televiewer housing and simultaneously moves radially inwardly and outwardly thereacross to image an entire solid angle across a transverse section of the borehole ahead of the televiewer.

Abstract: ABSTRACT OF THE DISCLOSURE A vinylidene chloride resin comprising 90 to 99% by weight of vinylidene chloride and 1 to 10% by weight of an acrylic or methacrylic monomer is mixed with 0.5 to 5% by weight, based on the resin, of a combination of a low-molecular-weight plasticizer and a high-molecular-weight plasticizer and 0.2 to 5% by weight, based on the resin, of a condensed phosphoric acid salt. Even if this resin composition is exposed to high temperatures, thermal decomposition of the vinylidene chloride resin is prominently controlled. When this vinylidene chloride resin composition is laminated with a thermoplastic resin having a thermoforming temperature higher than the thermoforming temperature of the vinylidene chloride resin, a packaging resin laminate having an excellent gas-barrier property is obtained.

Title: Process for causing gaseous trace element particles to pass from a flowing hot gas into a dust by means of water
Inventor: HAEMAELAE SIRPA
IPC: B01D53/34
Filed: 1988-05-10
Granted: 1992-04-14
Abstract: (57)Abstract The present invention relates to a process for causing gaseous trace element particles to pass from a flowing hot gas into a dust by means of water. According to the inven-tion, a mixture of the hot gas and water drops is caused to flow substantially up-wards at such a velocity that the water drops remain in the gas flow and for a period long enough for most of the mass of the water drops to evaporate in order to cool the gas and to increase its relative humidity. After the gases have reached their wet temperature they are brought into a turbulent state in order to cause the dust particles and the water drops which have decreased through evaporation to im-pinge against each other in order to pro-duce in the aqueous film which covers the dust particles an exothermal ion reaction between the gaseous water-soluble trace element particles and the dust particles. Thereafter the mixture is caused to flow further in order to evaporate the remaining water by means of the heat of reaction so that a dry end product is obtained.

Abstract: POWER REGULATOR FOR A PNEUMATIC      FASTENER DRIVING TOOL  Gilbert A. Cotta ABSTRACT OF THE DISCLOSURE A regulator for adjusting the amount of power generated by a pneumatic fastener driving tool of the type having a body connected to a source of air under pressure and containing a cylinder with a piston/driver assembly mounted therein and a main valve.  The main valve is slidably supported above the cylinder on a centerpost affixed to a cap closing the top of that portion of the tool body surrounding the cylinder.  The main valve is shiftable on the centerpost between a closed position engaging the upper end of the cylinder and shutting off the cylinder from the supply of air under pressure within the tool body and opening vent passages in the centerpost and cap to vent the cylinder volume above the piston to atmosphere, and an open position closing the vent passages and opening the upper end of the cylinder to air under pressure within the tool body to actuate the tool.  The regulator comprises an adjustable stop mounted in the centerpost and extending thereabout.  The stop is shiftable toward and away from the cylinder and determines the open position of the main valve and thus the size of the opening between the cylinder and the main valve, which determines the power generated by the tool.  An adjustment screw is rotatively mounted in the cap, having a first end above the cap and provided with a knob and a second end threadedly engaged in the stop to shift the stop.

Title: Foot operated door security device
Inventor: CHARLTON JOHN C
IPC: E05C19/00
Filed: 1989-01-13
Granted: 1991-08-06
Abstract: ABSTRACT OF THE DISCLOSURE   A door security device which is mounted in the floor or other flat surface in the arc of passage of a door which can be operated solely by one's foot. The door security device includes a housing with a flange plate which is mounted in the opening of the floor surface. A stop member is provided within the housing which assumes two alternate positions, a lowered position and a raised position. In the lowered position, the door is free to move through its arc of passage without obstruction by the door security device. By pressing down on the principal surface of the stop member, a latching mechanism is actuated which allows the stop member to be spring biased into the open position. In the open position the stop member obstructs the motion of the door through its arc of passage so that the door can be opened only a limited distance. To lower the stop member, one simply pushes down on the raised stop member a distance sufficient to actuate the pressure responsive latch mechanism that engages and holds the stop member in the lowered position. The, door security device is principally spring actuated and is preferably constructed of metal to provide good endurance and strength characteristics.
