Abstract: IMPROVED ANGEL FOOD CAKE MIX                      Robert E. Oborn ABSTRACT        An improvement in the art of culinary mixes containing dried desugared egg white, particularly angel food cake mixes, is provided by adding an alkali metal bisulfite thereto in an amount of from about 0.005% to about 1.0% by weight of the dried desugared egg white.        Preferably, the amount of alkali metal bisulfite added is from 0.05% to 0.50%.  Improved culinary products are also provided by adding the bisulfite to prepared dry culinary mixes.  Also disclosed is a process for the production of improved culinary products which require the use of less egg white, and in the case of angel food cakes, other improvements are cakes having substantially no cupping, whiter color, improved texture and improved recipe tolerance.

Abstract: ABSTRACT OF THE DISCLOSURE         Food temperature responsive apparatus for con-trolling an oven.  The apparatus includes a temperature sensing thermistor which may be included in a probe adapted for insertion into food being cooked in an oven.  The appa-ratus includes simplified and effective means, in the form of voltage dividers and comparators, for performing the functions of de-energizing the oven heating means and energizing an audible alarm when interior food temperature reaches a preset temperature, protecting against an open-circuited or a short-circuited condition in a sensing circuit which includes the thermistor, guarding against responding to transient electrical noise, and latching the oven heating means in a de-energized condition once it has been de-energized.  Even though the thermistor has a non-linear resistance versus temperature characteristic, the apparatus provides a linear temperature presetting scale and includes a linear temperature presetting potentio-meter.

Abstract: ABSTRACT OF THE DISCLOSURE          In an explosive power-driven setting gun in which a piston guide is axially displaceble within a casing and a driving piston is axially displaceable within the piston guide, a stop pin is provided for varying the volume of the combustion chamber for expansion of gasses within the piston guide at the rear end of the driving piston.  The stop pin extends between a locking piece in the rear end of the casing, through the rear end of the piston guide into contact with the rear end of the driving piston.  An adjustable stop surface for the stop pin can be provided integrally with the locking piece, or as a separate member movably mounted in the locking piece.  By ad-justing the stop surface the spacing between the rear end of the driving piston and the rear end of the piston guide is determined for establishing the initial size of the combustion chamber for the explosive gases which propel the driving piston.

Abstract: ABSTRACT           Following conventional pretreatment and background dyeing and washing of a carpet web, an applicator means applies a thick viscous gum coating to the pile face of the web, forming a temporary barrier thereon.  Conveyor means is provided to transport the coated carpet web horizontally through a liquid dye dripping or splattering station where multiple interrupted syrupy dye streams fall on the temporary barrier and form thereon dye pools and rivulets of irregular shape, size and spacing.  The conveyor means continues to transport the carpet web with the barrier coating and dye thereon horizontally into a steamer where the barrier layer dissolves and settles into the carpet pile with the dye to establish a random irregular color pattern.  Fixing of the dye also takes place in the steamer.  The apparatus has final washing and dyeing means of a conventional character beyond the steamer.  Pin driving rolls for the carpet web are electrically coordinated to maintain a regulated tension on the web at all times.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved method for further removal of sulfur from the tail gas of a conventional Claus plant by the use of a Cold Bed Adsorption process involving the specific improvement of maintaining at all times the lead Claus reactor of a series of such reactors at sufficiently high temperatures to promote hydrolysis of COS and CS2 and then utilizing part or all of the hot effluent gases of this lead reactor to regenerate the sulfur-fouled Cold Bed Adsorption catalyst by passing the hot stream through the fouled reactor, removing the deposited sulfur and then returning the stream to the Claus plant at a point essentially immedi-ately downstream from where it was originally withdrawn.  Such a method is useful in maintaining ultra-high sulfur conversion levels on a com-mercial scale.

Abstract: Abstract of Disclosure In a "first" scrubbing operation, the sulfur dioxide containing flue gas is scrubbed with an aqueous solution containing ferric sulfate and aluminum sulfate. The ferric sulfate oxidizes the sulfur dioxide to sulfuric acid, which dissolves in the solution, and is reduced to ferrous sulfate.  In a subsequent "second" scrubbing operation, the solution, now containing ferrous sulfate, aluminum sulfate, and sulfuric acid, is scrubbed with air. This regenerates, or re-oxidizes the ferrous sulfate to ferric sulfate.  The presence of aluminum sulfate accelerates the rate of regeneration.  The regenerated solution is then returned to its function in a "first" scrubbing operation, and the indicated cycle of "first" and "second" scrubbing operations are repeated.

Abstract: ABSTRACT         An electrophoresis apparatus and a multiple-sample applicator therefor.  Electrophoresis is a physical process in which electrically charged molecules and colloidal particles, upon the application of a DC current, migrate along a gel or a membrane wetted with an electrolyte.  If a membrane is used, its middle section is kept in tension horizontally above an electrolyte tank, while the ends of the membrane hang down into the electrolyte.  If a gel is used, it is held in a tray which is placed on a cooling plate, and wicks make contact with the electrolyte.         The applicator coacts with the tank cover to permit an operator to either depress a single button to deposit multiple samples on the gel or membrane simultaneously, or to selectively depress one or more sample applicators separately by a separate button for each applicator.         Greater resolution is achieved by performing two orthogonal migrations in a square gel tray by rotating it 90° after the first migration.
