Abstract: METHOD FOR METALLIZING CERAMIC GREEN SHEETS                     Abstract A process for metallizing a ceramic green sheet having via holes or recessed grooves formed therein by depositing a mask forming material over the green sheet, the mask forming material being non-wettable by a composition, either conductive or nonconductive, to be subsequently deposited in the via holes or recessed grooves.  After the depositing step, a metal paste is spread or wiped into the vias and grooves and then the sheets are laminated and fired to form a multi-layer ceramic interconnection package whereby the mask forming material is volatized and eliminated from the structure without the necessity of removing the mask forming material in the conventional etching or peeling away methods.

Title: Thermosettable powder coating composition comprising a blend of two coreactive polyfunctional copolymers
Inventor: LABANA SANTOKH S
IPC: C09D163/00
Filed: 1974-11-20
Granted: 1978-12-05
Abstract: ABSTRACT OF THE DISCLOSURE      Powder coating compositions are disclosed which comprise a blend of coreactable, thermosettable copolymers one of which has at least two different functional groups while the other is qualitatively monofunctional and quantitatively polyfunctional.  Ordinarily, the polymer having at least two different functional groups, will be quantitatively polyfunctional and qualitatively difunctional although it may contain more than two different functional groups.  In the preferred embodiments, the first or difunctional copolymer of the blend has either (1) epoxy functionality and amide functionality, (2) epoxy functionality and hydroxy functionality, (3) carboxy functionality and amide functionality, or (4) carboxy functionality and hydroxy functionality and is cross-linkable with the second copolymer through at least two dif-ferent types of functional groups on the first copolymer. The second copolymer has only one type of functionality that is crosslinkable with the functional groups on the first co-polymer and may be termed the monofunctional copolymer al-though it is quantitatively polyfunctional.  The second co-polymer may have as its functionality (1) anhydride func-tionality, (2) carboxy functionality or (3) epoxy functionality. The second copolymer is advantageously employed in an amount such that it provides about 0.4 to about 1.4, preferably about 0.8 to about 1.1, functional groups per functional group on the first copolymer.

Abstract: ABSTRACT OF THE DISCLOSURE      This injection blow molding machine has special pro-vision for maintaining the plastic of a parsion on a core rod at the orientation temperature of the plastic; and stretch-ing the plastic of the parison lengthwise of the core rod for orientation in the direction of one axis without any substantial increase in the diameter of the parison.  After this orientation in one axis, the temperature is controlled to maintain an orientation temperature, and the plastic of the parison is then blown to a larger diameter so as to ob-tain orientation in another axis for "bi-axial orientation". The core rod is covered by an elastic balloon, and prevision is made for obtaining floe of the plastic on the core rod lengthwise of the rod during the first orientation operation.

Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus and method for generating heat in which a particulate sulfur-containing fuel material and a sulfur absorbing material are passed into a chamber, are fluidized by passing air through the chamber, and are combusted in the chamber.  A second chamber is provided which receives the sulfated sorbent material both from the air passing through the first chamber and directly from the first chamber.  The sulfated sorbent material is desulfated in the second chamber before being passed back to the first chamber, and the remaining sulfur enriched gas is contacted with granular coal to reduce it to sulfur and hydrogen sulfide.  The recovery of sulfur in the above manner substantially reduces air pollution by the effluent gases passing from the first chamber into atmosphere.

Abstract: AIR GUN MONITORING AND SYNCHRONIZING METHOD AND APPARATUS Disclosed is an improved air gun construction which lends itself to use with a plurality or array of similarly improved air guns which enables easy synchronization and timing of such array of air guns relative to one another. The synchronization and timing is achieved by controlling and monitoring the movement of the shuttle in the air gun. Various sensors are used such as an electrical coil having a constant current flowing therein which produces a flux pattern which is modified when the shuttle is accelerated, thereby inducing a voltage in said coil which is processed by appropriate processing circuitry.  Another embodiment employs a magnetic sensor which includes a permanent magnet and coil wrapped therearound; the permanent magnet produces a flux pattern which is altered when the shuttle is accelerated and comes into proximity to the sensing end of said permanent magnet, thereby inducing a voltage in the coil which is then processed in appropriate processing circuitry. The processing circuitry associated with both embodiments generates a timing signal for each air gun which provides accurate phasing of each of the air guns to thereby fire such guns at a predetermined time.  The timing signals from each of the air guns are used in conjunction with additional signals to accurately indicate auto fire and no fire conditions of the air guns.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of selective plugging of undesirable high per-meability streaks and channels in oil-bearing reservoirs during high temperature (250°F or higher) injection recovery processes such as steamflooding or underground combustion.  Improved sweep efficiency can be effected by injecting a gel-forming solution consisting essentially of ammonium lignosulfonate and water or brine in the absence of other gelation promoters and then allowing the high temperatures of the underground formation to promote gelation.  Optionally, a precooling water injection step can be used prior to placement of the gel-forming solution.  This system has the advantage of gel times which are sufficiently long at temperatures in excess of 250°F to permit placement of large volumes characteristic of commercial use.  This method is partic-ularly useful in selectively forming firm strong gels in thief zones for steamflooding recovery operations.

Title: Process for coating sheet substrates with thermoplastic polymer
Inventor: PILGRIM JAMES F
IPC: B29C48/08
Filed: 1976-12-03
Granted: 1979-12-18
Abstract: An improved process for coating sheet substrates with thermoplastic polymer is disclosed. In the process the sheet substrate forms one die lip of the extrusion coating die. The sheet substrate is passed from face-to-face contact with the metal block of the extrusion coating die into a spaced apart relationship with one die lip of the extrusion coating die, that sheet substrate forming the second die lip. Molten thermoplastic polymer is extruded into the space between the one die lip and the sheet substrate, thereby coating the sheet substrate with polymer. The preferred polymer is a poly-.alpha.-olefin, especially polyethylene or a copolymer of ethylene and butene-1. The preferred sheet substrate has orifices in the surfaces thereof. The process may be used to coat sheet substrates with a thermoplastic polymer, e.g. in the manufacture of form boards for the construction industry.
