Abstract: ABSTRACT OF THE DISCLOSURE        Apparatus for supplying varied quantities of a gaseous curing agent to a rotary core making machine has a first piston and cylinder, a flow control for controlling the flow of a non-reactive gas from a source to either side of the first piston and for exhausting gas simultaneously from the other side of the piston in synchronization with the rotation of the core making machine.  A first valve has an electrically controlled inlet and outlet, and a second cylinder is aligned coaxially with the first cylinder, with a first piston rod connecting at one end to one side of the first piston and extending into the end of the second cylinder.  A second piston reciprocable within the second cylinder is attached on one side to the other end of the first piston rod and defining with its other side a chamber in the second cylinder.  A rotatable wheel is posi-tioned with its axis normal to the axis of the first and second cylinder, and a plurality of stops are mounted radially on the periphery of the wheel, the stops being variable in length and alignable coaxially with the second piston rod.  A sprocket wheel is attached coaxially to the rotatable wheel, a second piston rod is connected at one end to the other end of the first piston, and a pawl rod is fixed to the other end of the second piston rod, extending in the same plane as, and tangentially to, the sprocket wheel and adapted at its free end to engage the sprocket wheel when moved axially toward the first cylinder.          A first conduit is connected between the chamber in the second cylinder and a reservoir of liquid catalyst, a first check valve is located intermediate the ends of said first conduit, a second conduit is connected at one end to the first conduit inter-mediate the first check valve and the chamber in the second cylinder and is connected at its other end to the vaporizer nozzle.  A third conduit connects the source of compressed non-reactive gas and the inlet of the first valve, a fourth conduit connects the outlet of the second valve and the inlet of the vaporizer nozzle, and a fifth conduit connects the outlet of the vaporizer nozzle to a core making machine.

Abstract: ABSTRACT OF THE DISCLOSURE         A continuous steel casting process adapted to produce steel castings of satisfactory quality with less center segregations is described.  A molten steel is electromagnetically stirred in at least two of three locations, viz., a casting mold and intermediate and final solidifying zones of a continuously cast strand.  In the casting mold, is applied a magnetic field induced by alternate current of a frequency f=1.5 ~ 10 Hz and having G in the range of 195 x e-0.18f ~ 1790 x e-0.2f at the inner surface of the casting mold.  The intermediate solidifying zone employs a magnetic field induced by alternate current of a frequency f-1.5 ~ 10 Hz and having a magnetic flux density G in the range of 195 x e-0.18f ~ 1790 x e-0.2f at the surface of the strand or a magnetic field induced by alternate current of a frequency f=50 ~ 60 Hz and having a magnetic flux density G in the range of 0.6 x 106/(D-107)2 ~ 1.8 x 106/(D-100)2 (in which D=the thickness of a solidi-fied shell layer of the strand) at the surface of the strand.          For electromagnetic stirring in the final solidifying zone, a magnetic field induced by alternate current of a frequency f=1.5 ~ 10 Hz and having a magnetic flux density in the range of 895 x e-0.2f ~ 2137 x e-0.2f is applied.

Abstract: AUTOMATIC INTERMODULATION    DISTORTION ANALYZER                         Abstract A distortion  analyzer  is  disclosed which auto-matically measures intermodulation distortion accord-ing to the SMPTE-IM method. Variations caused by gain or attenuation as function of frequency in the device under test are automatically compensated. This automa-tion is accomplished by sensing the carrier level of the SMPTE-IM test signal and using this information in an automatic level control loop formed with a voltage controlled amplifier earlier in the signal processing path.

Title: Downhole seal for low profile oil well pumping installations
Inventor: JAMES ROBERT G
IPC: E21B33/10
Filed: 1981-04-16
Granted: 1983-09-13
Abstract: ABSTRACT OF THE DISCLOSURE:         Set out herein is a seal arrangement for sealing an oil well rod string below-ground surface.  More specifically a polished cylinder is inserted into the casing of an oil well and is supported at the well head by a flange radially extending from the upper end thereof.  Received in the cylinder is a piston assembly connected at the upper surface to a flexible string or chain articulated by a pump and supporting at the lower surface a polished rod sealably extending through a lower seal fitting received in the bottom end of the polished cylinder.  The cavity formed between the piston and the polished cylinder is aspirated into the well casing through a one-way check valve on the upward stroke of the piston and any oil residue that may pass through the lower sealing assembly is forced back into the well casing by another check valve opened during the downward piston stroke.  Both the piston and the seal assembly may include sealing rings to improve edge contact which thus render the down hole seal less vulnerable to hot gases and abrasive impurities commonly found in the course of secondary recovery.

Abstract: ENVIRONMENTAL CONTROL LIGHTING FIXTURES                           ABSTRACT           Front and rear facings of a lighting fixture, in conjunction with edge and internal members, form a cavity in which a light source (two diverse light sources in an alternate embodiment) is positioned for producing reflected light which is transmitted through a hidden light-transmissive portion of the front facing for illuminating a designated task area of the room. An additional light filter can be added.  An externally-located adjusting member is linked to the light source to allow adjustment of the position of a member of the light source so that the pattern of light passing through the light-transmissive member can be varied.  The fixture is brought into communication with heating (or airconditioning) ducts for dispensing heated (or cooled) air into the designated task area. The cavity communicates with an exhaust duct for exhausting heat generated by the light source, which heat is processed, preferably for reuse.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved electrolyte absorber for alkaline battery cells has low resistance to electrolyte ion transfer and can hold alkaline electrolyte in contact with an electrode during chemical reactions of the cell.          The absorber is formed by  depositing an improved wetting composition to a polyolefin substrate.  The substrate, preferably, is a fibrous and porous melt blown thermoplastic web made up of a plurality of physically entangled microfibers, resistant to strong alkali and oxidation.  The wetting composition which is deposited over and adhered to external surfaces of said microfibers is comprised of a substantially homogeneous admixture of a polymeric binder, inert hydrophilic filler particles and a phosphate ester wetting agent.  Portions of the filler particles in the composition protrude through the binder and are exposed in random distribution.  When the absorber is immersed in electrolyte, the phosphate ester wetting agent reacts with the electrolyte to lower the surface tension thereof.  The lowered surface tension permits the reacted electrolyte to rapidly wet the exposed filler particles.
