Abstract: REFRIGERATION SYSTEM CONTROL METHOD AND APPARATUS         ABSTRACT OF TEE DISCLOSURE     A refrigeration system contains a common compressor supplying refrigerant to a plurality of evaporators that are refrigerated and defrosted independently of one another. Indi-vidual refrigeration/defrost controls are provided in solid state form for the respective evaporators, and the individual controls are connected with a master control that prevents all of the evaporators from being defrosted at one time.  The master control includes a digital time clock providing time signals to each of the individual refrigeration/defrost controls, and each of the individual controls can initiate a defrost, operation for its respective evaporator on either a timed or demand basis.  The master control includes a scanner that interrogates the individual controls in a special manner to initiate defrosting of the units in order of priority.  The master control permits an individual defostcontrol for a selected evaporator to be tested in a timed mode by substantially increasing the speed of the time clock while operation of the remaining defrost controls is inhibited.

Abstract: ABSTRACT OF THE DISCLOSURE           The specification discloses an improvement in methods for recovery of petroleum substances from underground accumulations in earth strata.  Disclosed are means to enhance the contribution of compaction to recovery through well bores, and more particularly the recovery of viscous liquids and semi-liquids such as tars and bitumens.  Because means are shown for the recovery of earth strata solid materials associated with petroleum substances the present invention also is applicable to the recovery of any underground substance whether liquid or solid, which may be disintegrated by hydraulic or mechanical means at a distance from a well. Broadly speaking, this is a method of recovering petroleum substance from an underground accumulation in earth strata comprising:     (a)  drilling a first well into said strata, (b)  placing a substantial mass above said accumulation to compact said earth strata and reduce the porosity thereof, and (c)  expelling said petroleum substance into said first well.

Abstract: Abstract A method of sterilizing with a mixture of ethylene oxide gas and an inert gas which makes possible reuse of the ethylene oxide for an indefinite number of successive sterilization cycles. The gas mixture is refortified with ethylene oxide when necessary.  A portion of it is periodically vented when the increasing proportion of air produces a mixture which approaches the region of flammability of the mixture and is replaced with the inert gas to reduce the proportion of air in the mixture.

Abstract: A STAPLE CLINCHING MECHANISM     ABSTRACT OF THE DISCLOSURE         An apparatus in which articles are stapled to one another.  A staple is driven through the article so that a portion thereof protrudes therefrom.  The staple legs pro-truding through the articles are bent into substantial con-tact therewith so as to clinch the staples.  In the clinched position, the staple legs are closely adjacent to one another and may be overlapping.  During the clinching operation, the staple legs are guided by a groove in the surface affecting bending.  Initially, the stapled leg is received in the central region of the groove.  The central region of the groove has a greater cross-sectional area then the end region thereof.

Preferred compounds are ballasted sulfon-amido compounds, each of which has a color-providing moiety attached thereto through a sulfonamido group which is alkali-cleavable upon oxidation.  Preferred more reactive sulfon-amido compounds have a N,N-disubstituted carbamoyl ballast group.  The color-providing moieties can be (1) transferred imagewise to an image-receiving layer to provide a useful image, or (2) can be merely diffused out of the element to provide a retained image therein which can be treated to form a color transparency or a motion picture film.
