Abstract: ABTSTRACT OF THE DISCLOSURE     A slide fastener chain is fed along a chain path by a feedout mechanism until a leading end of the chain gripped by the feedout mechanism reaches a first feeder mechanism past a cutting mechanism.  The first feeder mechanism is then actuated to feed the chain toward a second feeder mechanism.  The first feeder mechanism is then inactivated and the second feeder mechanism is actuated to feed the chain at a higher speed.  A slider on the chain is engaged by a slider sensor to intermesh element rows on the chain as it is transported by the second feeder mechanism.  Then, a chain stop of a stop mechanism is inserted into an element-free gap in the chain and engaged by a bottom stop following the element-free gap to stop the travel of the chain.  The second feeder mechanism is released and a cutting mechanism is actuated to cut off the chain across the element-free gap to produce a slide fastener, which is discharged by the second feeder mechanism into a sorting mechanism.  Any defective slide fastener length having no slider is rejected by the sorting mechanism, and complete slide fasteners are delivered into a storage mechanism from which they can be picked up.

Abstract: Title MAIN BEARING LUBRICATION SYSTEM FOR SCROLL MACHINE                      Inventors Arthur L. Butterworth James C. Tischer Robert E. Utter Abstract A system for lubricating the main drive shaft bearings in a scroll compressor enclosed within a hermetic shell.  The drive shaft and its main bearings are supported in a frame that defines first and second chambers adjacent each end of a main bearing.  Each of the chambers includes an opening to a spatial volume contained within the com-pressor shell.  An oil pump at the lower end of the drive shaft supplies oil through a bore in the shaft to a swing link bearing and a thrust bearing, both disposed adjacent its upper end.  Oil is dispersed into the spatial volume as a mist of oil droplets by the rotating elements con-nected to the drive shaft.  Fan means are disposed within the second chamber and are operative to develop a differ-ential pressure between the two chambers so that oil drop-lets are drawn toward the first chamber, lubricating the main bearing as they pass through it.

Abstract: TITLE Method of and Apparatus for Monitoring a Rotary Kiln Assembly ABSTRACT    A problem that can occur with a large rotary kiln assembly is that it can move out of position or seals can become defective, making an escape of materials possible.  The present invention provides transducers (10, 15) for detecting movement of the rotary kiln itself or part of a seal assembly secured thereto relative to an inlet/outlet arrangement of the kiln assembly or a part of a seal arrangement secured thereto and also means whereby the condition of the seals can be monitored by following changes in the pressure or flow rate of a purge gas.  If the rotary kiln (2) should move out of alignment, then corrective action can be taken.  If the seals should leak, then they are changed.  A record of kiln movement is provided and if movement is excessive, an alarm (20) is sounded.

Abstract: Abstract of the Disclosure A continuous process for the production of alcohol, preferably ethanol, from cellulosic materials, is des-cribed.   The cellulosic materials are delignified such that the hemicellulose and the cellulose can be subse-quently acid hydrolyzed into simple sugars.  These sugars are fermented in the presence of yeast to yield ethanol and carbon dioxide.  The alcohol vapor is removed from the fermentation solution under a reduced pressure and subsequently distilled.  Carbon dioxide gas may be sparged throughout the fermenting solution in order to aid in the removal of the alcohol from the fermenting solution.  The gaseous carbon dioxide is captured and utilized in the manufacture of additional quantities of ethanol or other basic chemicals.

A combination of successive manual operations of the switches changes the modes from an intermediate one to a final one. At least one of the switches is operated plural times. An operation announcement is stored in a message processor (32) included in the processing circuit and displayed in the intermediate mode on a display unit (71) so as to specify the following modes to be selected. A plurality of message signals are stored in a random access memory included in the message processor. A part of each stored message is successively and rapidly displayed on the display unit. A decoder cooperates with the message processor in the processing circuit to detect a call number signal assigned to the pager receiver and delivers a sequence of clocks to the message processor.

Abstract: MULTIPLE IMPACT FASTENER DRIVING TOOL               ABSTRACT OF THE DISCLOSURE   A tool for driving fasteners by means of multiple impact blows.  The tool comprises a body with a handle portion and a magazine portion, shiftable in directions parallel to said blows between an extended position sub-stantially outside the body and a retracted position substantially within the body.  A prime mover provides a rotating shaft.  The rotating shaft is operatively con-nected to a mechanism for translating rotary motion into reciprocating motion.  The translating mechanism com-prises a flywheel, an impact member having at least one impacting surface thereon and being attached to or consti-tuting an integral, one-piece part of the flywheel, a free floating energy transfer member separate from but engageable with the impact member, a resilient bumper to arrest the energy transfer member at the termination of its drive cycle, and a fastener driver engageable by or comprising an integral, one-piece part of the energy transfer member.  A resilient member normally biases the energy transfer member out of contact with the impact member.  When the tool is abutted against a workpiece and pressure is applied by the tool operator, the at least one impacting surface of the impact member transmits blows to the transfer member, causing the transfer member and driver to be forcibly accelerated away from the impact member at a substantial velocity.  In this manner, the driver applies short, high velocity drive strokes in a rapid succession to the fastener to be driven.

Abstract: High-Intensity X-Ray Source A high-intensity X-ray source generates significant heat at the anode. To help dissipate this heat, the anode is often rotated in the vacuum. Heat must still be radiated from the anode to the exterior walls. An improved X-ray source incorporates the anode in the walls of the vacuum chamber and rotates the entire chamber. The heat is then easily conducted to the exterior where it may be dissipated by connection or forced air cooling.
