Abstract: TEMPERATURE CONTROL SYSTEM FACILITATING COOKING TEMPERATURE CALIBRATION IN SELF-CLEANING OVEN                 ABSTRACT OF THE DISCLOSURE     A temperature control system for an electroni-cally-controlled thermal cooking oven having a single oven temperature point in the field for normal cooking modes, without affecting the self-cleaning temperature calibration which is factory preset.  A sensor-developed analog voltage is employed to control self-cleaning temperature in the oven, with the oven temperature dur-ing normal cooking modes, such as bake and broil, con-trolled by the same voltage modified by an independently developed offset value or signal.  The required summing of the sensor voltage and the offset voltage preferably is done by means of a suitably-programmed microprocessor-based control system.  With this arrangement, the offset can be changed to vary the set point for normal cooking modes without affecting the self-cleaning temperature which is detected solely by the sensor, and cannot be readily varied by field adjustment.  Further, the field temperature calibration procedure is simplified due to a predictable discrete adjustment which eliminates cumbersome trial and error procedures.

Abstract: MUSCLE-BUILDING APPARATUS FOR DEVELOPING                   BENDING STRENGTH          Abstract of the Disclosure An adjustable apparatus for developing bending strength in the muscles of a user.  The apparatus simulates resistance encountered when attempting to bend metal bars with the arms outstretched forwardly and the hands initially in a horizontal, palms downward position, and thus develops specifically those muscles and skills required for such feats.  The apparatus is formed of two U-shaped members hinged at their open ends to form an O-shaped assembly.          Each U-shaped member has a handle attached near the middle of the base portions, for grasping by the user's hands.  Bend-resistant lengths of fairly rigid, yet resilient, material can be added successively between the U-shaped members to obtain an increased resistance to bending pres-sures, thus providing a device for progressively developing strength in the sets of muscles involved in bending strength.

Abstract: Abstract of the Disclosure Catalytic material is provided by a composition comprising the ele-ments vanadium, non-water-contained hydrogen, phosphorus and non-water-contained oxygen.  The VHPO elements are present in a relatively fixed atomic ratio range, there being more non-water-contained oxygen present than phos-phorus by an atomic ratio of greater than five to one.  The catalytic material comprises an anhydrous primary component having vanadium of mixed valence, hydrogen, phosphorus and oxygen in an empirical relationship defined by VHxPOy, wherein "x" has an average value in a range from about 1.29 to about 1.40, and "y" has an average value in a range from about 5.46 to about 5.55. The anhydrous VHPO catalytic material may also be described by a structural formula (VO)m(VO2)nH2n(PO4)n(P2O7)?, wherein m + n = 3, "m" has an average value in a range from about 0.90 to about 1.07, and "n" has an average value in a range from about 1.03 to about 2.10.  The primary component is mostly amorphous and in its substantially anhydrous form is characterized by a powder X-ray diffraction pattern having board peaks with CuX or d-spacings of 4.30, 4.17 and 3.09.ANG..  The catalytic material is prepared by a process comprising the steps of reducing vanadium pentoxide with a reducing agent in an aqueous solution of phosphoric acid, followed by the step of oxidizing a portion of the vanadium species with an oxidizing agent to form a slurry of precipitate containing vanadium(IV) and vanadium(V) in contact with a water solution con-taining vanadium(IV).  Subsequent removal of free water from the slurry provides a material which may be further heated to drive off water of hydra-tion and thereafter calcined to fix the relative amounts of the VHPO elements in the anhydrous material.  Freshly prepared catalytic material provides relatively high yields upon its initial use in the catalytic coxidation of hydrocarbon feedstocks, such as n-butane and benzene, to maleic anhydride.

Abstract: ABSTRACT OF THE DISCLOSURE    A tuned transformer element has its primary winding coupled, in series with a fuse of preselected rating, to the rails of the track circuit.  A secondary winding supplies in-put energy to the track circuit receiver unit which detects occupancy conditions of the track section.  A third winding is capacitor tuned to resonate with the primary winding at the track circuit frequency.  Thus the transformer appears as a parallel resonant load of high impedance in multiple with the track receiver which then operates normally.  At propul-sion frequency, the impedance of the primary is small while the parallel capacitive reactance is large, so that the parallel network gives the transformer unit a low impedance at this frequency.  If, due to unbalance in the rails, the propulsion current is large enough that its harmonics may energize the track circuit receiver to improperly register an unoccupied track section, the current in the primary winding exceeds the fuse rating and that primary circuit is opened to inhibit any track circuit receiver response.

Abstract: Abstract of the Disclosure POLYETHYLENE ISOPHTHALATE HAVING   REDUCED CYCLIC DIMER CONTENT     AND PROCESS THEREFORE   This invention relates to polyethylene isophthalate (PET) and copolymers thereof having low cyclic dimer content and process for making same.  The invention provides a process for making PEI using pro-tonic acid catalysts which result in a polymer having lower amounts or ring dimer of ethylene isophthalate than has heretofore been known.  Strong protonic acids such as sulfuric or phosphoric are utilized as poly-merization catalysts to thereby lower the amount of cyclic dimerization which occurs during the polymeriza-tion process.  Polymers so produced are of a high purity and have reduced manufacturing costs due both to a smaller amount of material being lost as cyclic dimer and because of lower processing costs associated with cleaning cyclic dimer from the processing equipment.
