Apparatus for transferring a layer of a decorative material from a foil, onto a work piece surface. Said apparatus includes means for accurately metering the necessary degree of heat to the work piece, to achieve the transfer. The heating means include a thermal belt that is sequentially heated and applied to the work piece surface. The temperature of the thermal belt is accurately modulated through at least a pair of rotatable guide rollers which retain and position the belt. The method include...

A coating apparatus in which a coating film is transferred from a film carrying roll leaf, onto the surface of a product. A positioning platform, together with a pressure member which acts against the platform, define a transfer station at which the roll leaf and product are concurrently aligned. A continuously moving and guided thermal belt preheats the foil sufficiently to effect separation of the roll leaf decorative layer from the carrier, and assure its transfer to the product surface.

Method and apparatus for continuously monitoring a moving yarn line to detect the presence of undesired denier imperfections. The yarn is passed through an elongated constricted passage sensing device into which a sensing fluid is concurrently fed. The back pressure thus created in the fluid carrying line due to flow resistance in the sensing device, is monitored to detect variations which would indicate an imperfection in the moving yarn line.

Mixing apparatus for a plurality of liquids and including an elongated passage for carrying one of said liquids to a mixing chamber. Said passage includes check valve means which opens into a distribution head which in turn forms a multiplicity of lateral streams. The second fluid is introduced to the mixing compartment by way of an inlet chamber which establishes an annular flow in a direction normal to the flow of the laterally exiting streams. The combined mixture is then discharged through a...

Method and apparatus for treating an oil-in-water, such as a bitumen-in-water emulsion, by premixing the emulsion for a sufficient period of time to permit it to become fully intermixed with emulsion breaking diluents and other additive materials. The modified, bitumen-containing emulsion stream is circulated through a premixer. At least a part of the emulsion stream is recirculated therein to intermix with fresh incoming emulsion flow. Thereafter the now more thoroughly intermixed emulsion, tog...

The invention concerns the internal structure of a high temperature furnace. That structure includes a dome made of refractory bricks that are capable of withstanding the high temperature within a coal gasification generator. The structure also includes a supporting brick wall under the dome. And, it includes an inner wall made of refractory bricks. The latter is inside of the supporting wall. The inner wall shields the supporting wall from the highest temperature while it is free to expand with...

A pulling head adapted to removably engage the end fitting of a conduit to facilitate the latter being pulled with a substantial tensional force. The head includes an engaging ring at one end thereof which is removably operable to register about and firmly engage the cable end fitting. A wire line extending from the pulling head nose end is attachable to a winch or other mechanism capable of applying the necessary pulling force thereto.

Method and apparatus for recovering hydrocarbons from a subterranean formation in which a well completion, including a well liner, lies in a generally horizontal disposition within the hydrocarbon productive substrate. The liner encloses conductor means for delivering a stream of a hot stimulating agent to the well's remote or injection end, and means for regulating the production of bitumen emulsion from the producing end thereof. A fluid impervious barrier is movably interposed in the well lin...

Coal gasification apparatus wherein a combustible mixture is formed and burned, comprising a combustion supporting gas such as oxygen, and a coal slurry. The hot products of combustion which issue from the burner, are directed into the reaction chamber of a synthesis gas generator. To avoid deposition of slag and ash particles along the hot, exposed face of the burner, a dynamic fluid blanket or barrier is directed transversely of the burner face. The reaction chamber includes an elongated port ...
