Abstract: ABSTRACT OF THE DISCLOSURE:         A method and apparatus for reducing the oxygen concentration of air within a preservation room such as the ones used for the conservation of fruits or vegetables. The apparatus comprises a compressor for pumping the air from the preservation room and circulating it through the apparatus, a device for heating the pumped air at a predetermined temperature, a device for mixing an inflammable gas with the air heated at the predetermined temperature, a catalytic combustion chamber wherein the gas is burnt with the oxygen of the heated air thereby producing air having a reduced oxygen concentration, and a spray water cooler for cooling the air with a reduced oxygen concentration before returning it back to the preservation room.  The apparatus may also be provided with thermocouples for measuring the temperatures of the heated air and of the air with a reduced oxygen concentration at the outlet of the catalytic chamber and a control circuit for controlling the mixing and heating devices as a function of the two measured tempera-tures.  The apparatus may also be provided with a heat exchanger for recovering the heat from the combustion chamber and using it to preheat the air before heating it.

Abstract: TOOL GRIPPING FASTENER     Abstract of the Disclosure A fastener comprising a head, a shank, and a cap.          The head has a recess in its top surface dimensioned to accommodate an appropriate tool for installing the fastener.  The cap covers a substantial portion of the head and conforms closely to the head, extending into the recess in spaced relation to a substantial portion of the inner surfaces of the recess and cooperating with those surfaces during insertion of the installation tool into the recess to present appropriate dimensions to the tool to resiliently grip the tool and accommodate the tool for proper installation of the fastener.   The cap is made of resilient material preferably stainless steel to provide corrosion resistance of the fastener once the fastener is fully inserted into the workpiece.  Additionally, the fastener is designed to accommodate and,through interaction of the cap and installation tool,resiliently engage commonly known standard installation tools to provide easy and safe installation of such fasteners yet permit easy disengagement of an installation tool after full installation of the fastener within a workpiece.

Abstract: Abstract of the Disclosure There is disclosed a hand-held labeler which uses labels releasably adhered to a carrier web. The labeler has a body with a pair of identical body sections.  The body mounts first, second and third feed rolls.  The first and third feed rolls project beyond the body and cooperate respectively with the second feed roll.  The body has a delaminator and a guideway for the carrier web.  The carrier web can be threaded through the guideway and about the delaminator in either direction.  In either event, the first, second and third feed rolls cooperate with the carrier web to advance it and effect label delamination.  Depending on the direction of threading, either the first or the third feed roll is used to advance the carrier web by rolling that feed roll along the surface to be labeled.  A label roll is held captive in a holder having two identical body sections.  In an alternative embodiment, a label strip winding feature enables a strip of labels to be wound into a roll for subsequent use in the labeler.  Common identical molded parts enable low-cost construction.  There are also disclosed method of making a labeler and method of labeling.

Abstract: TO ALL WHOM IT MAY CONCERN     BE IT KNOWN THAT WE, IAN PERCIVAL BROCKWELL, an Australian citizen of 239 Cottage Road, Wyckoff, New Jersey, United States of America and HERBERT WILLIAM HANCOCK, a British citizen of 29 Higher Street, Merriott, Somerset, England have invented certain new and useful improvements in CHEESE BLOCK FORMER     ABSTRACT         Cheese curd is fed into the top of a hollow perforated column in a tower at a sub-atmospheric pressure so as to form in the column a pillar of curd supported on a guillotine blade which closes off an opening in the bottom of the tower.  A former unit below the tower has an upright open-ended cylinder sealed against the bottom of the tower, and an elevator within the cylinder.   The guillotine blade is withdrawn, the pillar of curd lowered into the cylinder by the elevator, and the guillotine blade returned to its closed position so as to cut off a block of curd from the bottom end of the pillar of curd.  The elevator is then forced upwards to compress the block of curd within the cylinder.  The former unit is subsequently lowered, pivoted into a horizontal position, and the elevator driven along the cylinder to eject the block of curd.

Abstract: METHOD OF IMPROVED GAGE CONTROL    IN METAL ROLLING MILLS             ABSTRACT OF THE DISCLOSURE       In a metal rolling mill of the type employing automatic gage control (AGC) to control the gap between the rolls utilized to reduce the thickness or gage of a workpiece passed between the rolls, there is provided a method for compensating for roll irregularities (e.g., eccentricity and ovalness).  The method provides for developing signals proportional to the roll separation force and the roll rotational speed and isolating the force signal those cyclic components which have a frequency which is an integral multiple of the roll rotational speed.  The values of these cyclic components are then multiplied by a factor greater than unity and the resulting product is substracted from the original force signal to thus develop a modified force signal which is utilized to control the AGC and hence the roll gap to thus compensate for roll irregularities.

Abstract: ABSTRACT     POROUS MULLITE           Clay convertible by thermal treatment into crystalline mullite and silica is formed into green coherent bodies of desired size and shape such as, for example, microspheres, pellets or honeycombs.  The bodies are then calcined to convert the clay into a mixture of crystalline mullite and silica, thereby also hardening the bodies.  Without destroying the form of the bodies, e.g., without grinding and without causing the bodies to decrepitate, pores in the size range of about 150 to 350A are formed by selectively leaching silica from the bodies.          The porous mullite bodies retain porosity at elevated temperatures and are useful, for example, as catalyst supports and contact materials.  Pore structure in the meso- (100-600A diameter) and macro- (600-20,000A diameter) size ranges may be controlled.
