Abstract: TITLE                  POWDER COATING COMPOSITIONS COMPRISING A GLYCIDYL ACRYLATE, AN ALPHA-BETA OLEFINICALLY UNSATURATED AMIDE AND OLEFINICALLY UNSATURATED MONOMERS     ABSTRACT OF THE DISCLOSURE       Powder coating compositions are disclosed which comprise a copolymer of about 5 to about 20 weight percent of a glycidyl acrylate, about 2 to about 10 weight of an alpha-beta olefinically unsaturated amide, e.g., acrylamide and methacrylamide, and about 70 to about 93 weight percent of other olefinically unsaturated monomers in combination with an anhydride crosslinking agent.  Other materials such as pigments, catalysts, flow control agents and plasticizers are used in individual compositions.  Such compositions constitute an improvement over heretofore disclosed coating materials of otherwise similar composition which do not include the amide component of the copolymer.

Abstract: ABSTRACT     In idler roller assemblies for belt conveyors one race of a bearing is fixed to a support while the other race carries an element engaged by a member of the roller, one of the element and member having a cylindrical projec-tion engaged in a socket in the other.  In a previous construction, relative rotation between the element and member was prevented by the engagement of flat surfaces provided on both element and member in the form of a polygonal cross-sectional projection engaging in a comple-mentarily shaped recess.  The flat surfaces rock against one another due to engineering tolerances permitting some clearance and initially or after wear "chatter" can reach intolerable levels.   According to the present invention the construction has a curved surface on one of the element and member arranged to engage and jam with a part of the other as in a preferred embodiment wherein the element or member having the cylindrical projection has a cylinder portion eccentric to the projection and engaging in a complementary recess in the element or member having the socket.  The arrangement being such that an initial relative rotation between the element and member about the axis of the cylindrical projection causes the cylinder portion to jam in the recess to prevent further relative rotation and thus prevent the occurrence of "chatter".

Abstract: ENZYMATIC HYDROLYSIS OF CELLULOSE                 Abstract of the Disclosure In the enzymatic hydrolysis of cellulose to obtain water-soluble sugars, the enzyme source is the aqueous culture mass obtained in an enzyme preparation step by cultivating in an aqueous nutrient medium in the presence of a cellulosic material a cellulolytic microorganism capable of elaborating a cellu-lolytic enzyme complex which can degrade native cellulose.  No separation is made of any component of the culture mass.  Such use of the culture mass as the enzyme source not only eliminates processing steps to separate the enzyme, but also results in increased hydrolysis rates and yields of the desired water-soluble sugars in the hydrolysis of cellulose.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention relates to an electrically heated glazed door structure for use in refrigerated display cabinets.  The use of an optically transparent electrically conductive coating for preventing moisture condensation on the frontmost glazed surface of a refrigerated cabinet door is known.  Such coatings, normally applied to the unexposed surface of the frontmost glass pane are in current wide use.  This heating technique performs well where the ambient air has a relative humidity which is not excessive.  When such refrigerated cabinets are used in highly humid environments, it is found that even though the frontmost pane remains frost-free, the innermost pane (the pane which has been exposed to the interior environment of the cabinet) has a tendency to collect condensation while the door is open, The condensation turns to frost when the refrig-erated cabinet door is closed, thereby substantially impairing the door's ability to attractively display products stored in the cabinet until such time as the door recovers its frost-free condition.  The present invention decreases the frust-free recapture time of a multi-pane glazed door such as is used on refrigerated display cabinets, by selectively heating the innermost pane when it is exposed to high relative humidity conditions.  An electric current is passed through an optically transparent electrically conductive layer on the unexposed surface of the innermost pane.  This heats the pane to a temperature above the dew point of the ambient air.

Abstract: Abstract of the Disclosure The apparent source of sound from a plurality of transducers arrayed around a listening area is auto-matically controlled by a prestored pattern sequencer and a series of variable voltage levels.  The prestored patterns reflect switch connections to the transducers which are energized by varying signals so that the sound appears to the listener to move relative to the transduc-ers.  In one embodiment, varying analog signal levels are switched under pattern control while, in another embodi-ment, the controls are entirely effected with digital circuitry up to the final analog output stages.  The sequences of switch patterns can be automatically select-ed or operator selected and can provide the effect of ro-tating sound or any of a wide variety of prestored patterns.

Abstract: METHOD AND DEVICE FOR DISPENSING PORTIONS OF A CHAIN                 ABSTRACT OF THE DISCLOSURE         The method and device are particularly adapted to dis-pense portions of a chain having relatively diametrically enlar-ged segments therein, such as master links, which are disposed at substantially regularly spaced intervals along the length of the chain, although the intervals may not and in fact need not be un-iformly spaced.  According to the method, the chain is supported so that it is movable relatively lengthwise thereof through the opening in a collar which is capable of being opened and clo-sed about the chain, and the opening of which has a diameter of less than that of the relatively enlarged segments of the chain in the closed condition of the collar.  When the collar is open, the chain is advanced lengthwise in the direction of the collar to the extent that a portion of the chain including one rela-tively enlarged segment therein, is fed through the opening in the collar and assumes a position on the opposite side thereof.          Then the collar is closed, the chain is tensioned against the collar, and the chain is severed at a point on the opposite side of the collar to dispense the portion.

Abstract: ABSTRACT OF THE DISCLOSURE          An intrusion alarm system has a number of satellites each connected to a master by an unshielded cable having only four conductors, namely two power conductors, a drive signal conductor which supplies drive to the satellite transmitter and the satellite control circuit, and an alarm conductor.  When an intrusion is detected by a satellite, its control circuit transmits a high level alarm signal on the alarm conductor to the master and also enables (but does not operated a speaker in the satellite.  The master has a rocker switch which an investigator turns of when he arrives at the supervised premises.  This turns off the drive signal to the satellite.          The control circuit of the satellite that caused the alarm responds by sounding its speaker, enabling determination of where the alarm occurred.  The rocker switch may also be placed in a walk test position, enabling the system to be walk tested, and then may be returned to its initial super-visory position applying a reset signal to restore the satellite control circuits all to their normal supervisory condition.  A tamper switch operates if a satellite is tampered with and causes transmission of a high level tamper alarm signal, different from the intrusion alarm signal, to the master.
