A multiple cathode DC arc plasma generator arrangement is used in connection with a single anode for thermal arc plasma processing of materials. A nozzle is provided to introduce a gas in approximately the center of the multiple cathodes, towards the anode. The nozzle injects the gas into the center of the plasma column generated between the cathodes and anode to stabilize such arc and affect the self-induced electrode jets. This provides control of the heat transfer to the anode and permits fee...

A joint is provided which can serve for connecting two elements, but can also be employed for making a column or pole like structure. The joint consists of two superposed plates or frame shaped bodies which are interconnected by two pairs of crossing rods. The joint serves to connect two modular parts in a chain-like construction.

An improved method for depositing a pour point depressant in an oil producing formation so that the pour point depressant can slowly dissolve in the oil as the oil is produced which comprises the steps of: A. Adding an activator for the pour point depressant into the formation, and then; B. Injecting a dispersion of the pour point depressant into the activator treated formation.

A mechanism which greatly reduces the number of components to be manufactured and assembled, and incorporates a kinetic energy storage system into a printing arm-stylus arrangement, and by which incorporation, stored or resilient energy is utilized to provide the stylus with an initial velocity greater than zero with rebounding from impaction with a surface or the like. An auxiliary mass is resiliently or spring-related to the stylus on the one hand, and resiliently or spring-related to a cantil...

A motor utilizing, at least in part, buoyancy forces of different materials in a fluid is disclosed characterized by a piston assembly that requires only a single level fluid pool utilizing no pump to operate.

A bed wherein a spring foundation supports an air mattress. The air mattress is formed from two air-impermeable sheets, each sheet having been vacuum-formed to provide a plurality of aligned recesses. The sheets are sealed face-to-face so that the aligned recesses form a plurality of cells that are inflated, approximately 20 rows of cells extending the length of the mattress.

A communications system each end of which includes means for analyzing human speech and comparing each word to prestored words for word and speacker recognition, the message then being digitized along with characteristic properties of the speackers voice to form a signal for transmission having a rate of approximately 75 bits per second, transmitting the digitized message to a remote terminal which converts it to a spoken message in the synthesized voice of the original speaker.

Compositions and methods are provided for identifying and diagnosing individuals at risk for a disease state associated with aberrant Rad41 foci.

A lotion for treating the symptoms of arthritis using capsaicin and an analgesics, and a method for making.

A method for filling a powder container, including the steps of placing a first powder container to be filled in filling relationship to a supply of powder in a vessel, vibrofluidizing the powder in the vessel to improve its flow properties, dispensing powder from the vessel into the first container, removing the first container from the vessel, and placing a second container to be filled in filling relationship to the vessel.
