Abstract: ABSTRACT     A recirculating sprayer adapted for mounting on a vehicle is improved for use at increased travel speed and dor operation in higher wind conditions by angling the solid spray streams forwardly or rearwardly from a direc-tion transverse to the travel direction.  The sprays are employed in criss-cross, opposite pairs, with the spray stream patterns of adjacent pairs of spray nozzles abutting or overlapping one another for full coverage of all up-standing weeds or crops in an area traversed by the sprayer.          A series of collector mats or panels may be arranged transverse to the travel direction, with sprays trained thereon for contacting each weed twice in its upstanding position once by each spray of a pair; the weeds may also be contacted once more as they are bent forward to pass beneath the panels and a reservoir thereunder.  The col-lector may also be arranged in panels parallel to the travel direction for increased ease in negotiating sloping terrain.  Spray liquid is collected from the collector panel(s) into reservoirs therebelow and is recirculated for reuse.

Abstract: ISOLATING MEMBER FOR USE IN CONTACT PRINTING                 Abstract of the Disclosure Apparatus and method are disclosed for use in contact printing information from a master record carrier onto a replicate material of a type that emits a gas during the contact print exposure (e.g., a diazo film emulsion). Even though the master record carrier and the replicate material are pressed together by a pressure pad (e.g., a rubber diaphragm), it has been discovered that the emitted gas causes the master and replicate devices to separate slightly and that strain forces in the pressure pad are transmitted to the replicate material causing relative movement of the master record carrier and the replicate material during the contact print exposure.  To limit such relative movement, a preferred embodiment of the present invention provides an isolating member disposed between the master-replicate sandwich and the pressure pad. The isolating member, because of certain physical character-istics discussed in detail below, prevents strain forces in the pressure pad from being transmitted to the replicate material.

Abstract: SLURRY PUMP TRAM CONTROL APPARATUS Abstract Method and apparatus are described for removing material from a sump.  The sump has substantially parallel and elongated sidewalls and has a longitudinal axis.  The sump is enclosed with ends and a bottom and is adapted for filling with a water-solid mixture to form a slurry.  A suction pump is mounted above the sump and extends into the sump for removal of water and solid material.  Apparatus is attached to the suction pump for moving the suction pump along the longitudinal axis of the sump.  The actual rate at which the suction pump is trammed is determined by apparatus which measures the concentration of the slurry near the pump and transmits a signal to a control unit which operates the tramming control circuit to maintain the concentra-tion at a predetermined ratio of material to water.

Abstract: IMPROVED PROCESS FOR EXPANDING TOBACCO       Abstract of the Disclosure This invention relates broadly to an improved process for expanding tobacco and involves certain modifica-tions of the basic process for expanding tobacco comprising the steps of (1) contacting the tobacco with liquid carbon dioxide to impregnate the tobacco with the liquid carbon dioxide, (2) subjecting the liquid carbon dioxide-impregnated tobacco to conditions such that the liquid carbon dioxide is converted to solid carbon dioxide and (3) thereafter subjecting the solid carbon dioxide-containing tobacco to conditions whereby the solid carbon dioxide is vaporized to cause expansion of the tobacco.  The present invention pertains, in one embodiment, to an improvement in the basic process which involves controlling the moisture content of the tobacco which is employed in the first step of the basic process.  A second embodiment of the present invention involves draining off excess liquid  carbon dioxide, under controlled conditions, after the first step of the basic process and prior to the second step of the basic process.          The present invention pertains, in a third embodiment, to an improvement which involves controlling the output moisture of the product which is recovered from the third step of the basic process.  The present invention further relates to various combinations of the three embodiments set forth above and to an overall process which employs all three embodiments in a manner which permits exceptionally advan-tageous results.
