Abstract: MOTOR PROTECTION CIRCUIT                 Abstract of the Disclosure A protection circuit protects a motor against excessive energizing current and exposure time conditions in accordance with the inverse re-lationship existing between these quantities.  The circuit includes a pulse generator which generates a pulse train signal having a pulse rate proportional to the magnitude of the excess current applied to the motor.  The pulses of the pulse train signal are counted up in a counter to a predetermined number. When that number is reached, the circuit operates to disconnect the motor.  The greater the excess motor current, the higher the pulse rate of the pulse train signal, and the shorter the counting time required to obtain the predetermined number.  The inverse re-lationship between excess current magnitude and exposure time is thus obtained.  The circuit indicates when excess current is being applied to the motor and retains that indication after disconnection.

Abstract: COMBINATION OF HOLLOW MEMBER AND BACKING MEMBER            Abstract of the Disclosure Disclosed herein is an improved combination of a hollow member and a backing member to be inserted therein.          Another member such as a hinge is secured to the hollow member by machine screws which extend through the hinge and the wall of the hollow member and are tightened in threaded holes in the backing member.  The hollow member is provided with an inwardly extending pawl and the backing member is adapted to be placed in a desired position in the hollow member by engagement with the pawl.  When a plurality of backing members are to be placed in the hollow member, a plurality of pawls are formed in the hollow member so that they are laterally offset from each other with respect to the longitudinal direction of the hollow  member and a void portion is formed in each backing member so that the pawls above the intended pawl do not interfere with the backing member as it is inserted in the hollow member.

Abstract: Abstract The optical elements of a copier are automatically aligned by positioning the elements under the control of signals from an image-dissecting scanner.  The scanner, mounted to receive the image normally pre-sented to the photoconductor, examines a master document placed in the position normally occupied by a document to be copied.  Optical adjustments are made as a function of the examination of lines on the master document by the scanner.  The contrast between a line and its background is maximum when optical elements between the master document and the scanner provide the sharpest focus of the line image to the scanner.  Signals from the scanner for a plurality of lines on the master document determine optimum posi-tioning of the optical elements.  The scanner deter-mines the apparent spacing between lines, which are a known distance apart on the master document, to position the optical elements for a desired magnifica-tion.  The positions of selected lines, examined by the scanner, relative to absolute reference points are used to align the master document support for subsequent copying of original documents.            Digitized light-level value samples from the scanner are pushed into a last-in/first-out stack.  A value significantly less than the average of the values in the stack indicates that the scanner has found a line.  A plurality of scans of the line are then made while adjusting the optical elements.  Corresponding light values are pushed into the stack and the average of the values stored in the stack is calculated.  If the average is greater than previously calculated averages, a number of additional scans are made to insure that the best focus adjustment has been identified.

Abstract: ABSTRACT          Compositions which are stable in the absence of oxygen are formed by mixing the following substantially in the absence of oxygen (A)  100 parts by weight of a mercapto-functional organosiloxane containing an average of at least two mercapto-functional substituents per molecule; (B)  0 to 200 parts by weight of at least one filler; (C)  a catalytic amount, preferably from 0.1 to 6 parts by weight, of an iron carbonyl catalyst selected from the group consisting of Fe(CO)5, Fe2(CO)9, Fe3(CO)12, dicyclopentadienyldiiron tetracarbonyl, butadieneiron tricarbonyl and cyclohexadieneiron tricarbonyl; and (D)  0.1 to 6 parts by weight of an acid which meets a particular set of criteria. The compositions polymerize or cure to form higher molecular weight products at room temperature upon exposure to oxygen. These compositions are especially useful as coatings because they possess a rapid rate of surface cure at room temperature. Elastomeric sealant compositions can be prepared which rapidly become  ack-free at room temperature and are therefore less prone to surface contamination by foreign matter such as dust.

Abstract: ABSTRACT    The present invention relates to an apparatus for controlling the rate and extent of cutting slots in flow conductors, particularly casing in wells.  The apparatus is hung in the well from a pipe string, locked in position and force applied to the string.  A hydraulic metering mechanism acts against the applied force to control the rate of travel of one or more jet bodies attached to the movable mandrel of the apparatus, the stroke of which determines the extent of the cut.

Abstract: Abstract The present invention comprises a method of preparing vinyl chloride polymers or vinyl chloride copolymers suitable for the preparation of plastisols. The method can be used in polymerizations, wherein n pre-emulsion of a substance having a very low solubility in water, is caused to swell by the vinyl chloride monomer, whereafter the  monomer emulsion obtained is subjected to polymerizing conditions.  According to the invention the emulsion is stabilized, and, by polymerizing in the presence of an stabilizing latex, it is possible to avoid the latex obtained becoming unstable.  In this way it is possible to prepare polymers having a suitable particle size and particle size distribution to enable low viscosity stable plastisols to be prepared therefrom.

Abstract: ABSTRACT OF DISCLOSURE           A novel family of crystalline, microporous aluminophosphate  compositions is synthesized by hydro-thermal crystallization at elevated temperatures of aluminophosphate  gels containing a molecular structure-forming template. The family comprises a number of distinct species, each with a unique crystal structure. Calcination removes volatile extraneous matter from the intracrystalline void space and yields microporous crystalline adsorbents with uniform pores, the dimensions of which vary, along the individual species, from about 3A to 10A in diameter.  The compositions represent a new class of adsorbents of the molecular sieve type, and also exhibit properties somewhat analogous to zeolitic molecular sieves which render them useful as catalysts or catalyst bases in chemical reactions such as hydro-carbon conversions.
