The selected Lewis acids which can be employed are sulfuryl chloride, chlorosulfonic acid, thionyl chloride, benzenesulfonyl chloride, benzenesulfonic acid, ortho- or para-toluenesulfonyl chloride, and ortho- or para-toluenesulfonic acid. Methods for making the sizing compositions and paper which is sized with the sizing compositions are also disclosed.

Abstract: There are disclosed prefermented, dehydrated potatoes having a low moisture content and a relatively low tendency to brown during frying. Potatoes of undesirably high reducing sugar content are fermented to lower their reducing sugar level before they are extensively dehydrated to a low moisture content, and the resulting products may exhibit less browning upon subsequent rehydration and frying than potatoes whose reducing sugar content is relatively high and is decreased by fermentation after being highly dehydrated to the low moisture content. Also, the potatoes which are fermented before dehydration exhibit a good rate of reducing sugar decline during fermentation, and may have less yeasty or fermentation taste upon frying, than potatoes which are fermented after drying to a low moisture level. Fermentation before extensive dehydration can be adequately and readily achieved even though the potatoes have a relatively high ratio of reducing sugar to total sugar.

The support strip has a support opening, and preferably a plurality of such openings.

Abstract: A rolling mill stand, particularly for a rod or bar mill, has, at each side of the pass line, a rotary roll housing which includes a number of fitments each for detachably carrying a roll assembly. By rotating the roll housings, one of the roll assemblies of each roll housing can be brought into a rolling position, in which it is coupled to drive means. In order to change the rolls at the rolling positions, each of the roll housings is rotated to bring a fresh roll assembly into position. The stand has a roll change rig enabling one or more of the roll assemblies of each roll housing to be quickly run out of the stand and replaced by substitute roll assemblies.

Abstract: There is disclosed a process for forming farinaceous dough ribbon of good quality and at a substantially constant rate. The ribbon is especially employed in processes involving further handling or treating of the dough as a ribbon of substantial length. Compositions comprising farinaceous solids and water are worked to the desired dough consistency in the barrel of an extruder. A positive displacement device is located between the barrel of the extruder and a die to discharge the dough ribbon from the die at a substantially constant rate. The production of ribbon of acceptable quality can be readily maintained. When an undesirable variation in ribbon quality appears, it can be counteracted by controlling only one process variable in the extruder barrel. The dough ribbons are particularly useful in the preparation of cooked snack food products, e.g., fried corn chips.

Abstract: There are disclosed farinaceous dough products having good organoleptic characteristics, especially desirable flavor and taste, which are dough products having a minor portion of the surface of the product selectively toasted by localized heat before the total product is fried or baked. The heat applied to the dough surface is controlled so as to toast the minor portion of the surface without removing too much moisture from the remainder of the dough. The finished product has a toasted flavor when consumed.

Abstract: Sodium thiosulfate is purged from a sulfur dioxide removal system involving contact of a sulfur dioxide-containing gas with a solution containing sodium sulfite to absorb sulfur dioxide from the gas. A portion of the liquid from a desorption zone containing a minor amount of sodium thiosulfate and a relatively large amount of sodium bisulfite, is treated to reduce the amount of water in the medium so that solids are precipitated from the liquid phase. The insolubles containing sodium sulfites are removed from the liquid. The liquid separated from the solids can be discarded and thereby purge thiosulfate more selectively with respect to other sodium salts. Also, the sodium values of the sodium thiosulfate-containing purge liquid can be recovered in active form by chemical reduction, and, preferably, carbonation. A sodium sulfate purge material from the absorption-desorption system can also be subjected to the chemical reduction system for further recovery of active sodium values.

Abstract: Sulfur dioxide in sulfur dioxide-containing gases is thermally reduced at relatively moderate temperatures under reducing conditions provided by the incomplete combustion of hydrocarbon to produce elemental sulfur. Elemental sulfur can be recovered from the effluent gases from the thermal reduction and the effluent gases may be treated by conventional catalytic processes to recover additional elemental sulfur from the remaining sulfur values.

Abstract: In accordance with the invention sulfur dioxide in sulfur dioxide-containing gases is converted under selective conditions to provide elemental sulfur in an efficient and economically-acceptable manner for present day industrial operations. The conversion involves the thermal reduction of sulfur dioxide in a zone at relatively moderate temperatures maintained by the combustion of carbonaceous fuel in the zone to provide elemental sulfur and to provide a gaseous thermal reduction effluent which is acceptable for further processing to recover additional sulfur values therefrom.

Abstract: Production of ethylene is disclosed by a route which involves hydrocracking of a C.sub.3 or higher feedstock, e.g. a gas oil, followed by ethane pyrolysis. The feedstock/hydrogen ratio is chosen to favor C.sub.2 production (mainly ethane but also a small proportion of ethylene) in the hydrogenation zone and the reaction is prevented from self-quenching by supplying to the hydrocracking reaction zone hot combustion gases produced by at least partial oxidation of a fuel.

Abstract: Apparatus that collects and transports generally spherical objects, such as tennis balls, and recycles them to a practice device that propels the balls to a tennis player for practice or recreation. Balls are fed one at a time to a chamber from whence they are metered to a transport device without jamming or bridging. Balls are fed or conveyed to a ball delivery zone by a pair of oppositely moving and aligned conveyor belts, each belt being located on opposite sides of the delivery zone. The delivery zone is of such dimensions that only one ball at a time can fall downwards thereinto. Located within the delivery zone is a horizontally reciprocating piston and oppositely opposed thereto and in alignment therewith is a ball exit port communicating with a vacuum tube leading to a pneumatic ball projector. As balls enter the delivery zone, they are fed through the exit port by the reciprocating cylinder and into the vacuum tube and served to a player by means of the projector.

Preferably, the material is fed to the rollers as a ribbon, and the cutters cut the material into one or more ribbons of articles and ribbons of trim.

Abstract: There is described the preparation of hydrophilic, semi-permeable film membranes having an increase in pores and containing complex-forming metals. The films can be formed from solutions having film-forming material and pore-forming material dissolved in a solvent. The films can be useful for separating a component, e.g. an aliphatically-unsaturated hydrocarbon, from mixtures by the combined use of liquid barrier permeation and metal complexing techniques. The liquid barrier is at least partially within the hydrophilic film membrane during use, and the barrier contains complex-forming metal ions in aqueous solution. The metal ions may be, for example, noble metal, nickel, mercurous, cuprous or other metal ions, and mixtures of these metal ions, and the aqueous solution may contain other cations. The separation of ethylene from ethane and methane is of particular interest.

Abstract: In a fluidized cracking unit, the cracking catalyst regeneration vessel is specially adapted for high temperature operation to permit essentially complete combustion of coke on the spent catalyst particles and, in addition, the essentially complete combustion of carbon monoxide produced thereby, within the dense phase zone of the regenerator. A partition in the regenerator divides the lower dense phase zone operating at high temperatures from the upper dilute phase zone which may be cooled, for instance, by boiler tubes, water sprays and the like. The partition contains one or more rough separation catalyst knock-out means such as cyclone separators whereby hot catalyst particles are separated from the rising combusted cases and returned to the dense phase regeneration zone. In one embodiment, the regeneration vessel is elongated to facilitate recovery of most of the extra heat produced by complete carbon monoxide combustion by the catalyst particles returning to the dense phase zone.
