Abstract: ABSTRACT          This disclosure sets forth an improvement in a method of making electrically heated glass substrates.  Basically the improvement involves forming glass separators from wax dots, the wax dots being formed of a wax material containing a filler material.  The filler material is one which holds the wax material in the location of the formed dot during burnoff of the wax material when the glass substrate is heated to a temperature sufficient so that the substrate may be bent to a desired configuration.  The filler material is also one which prohibits any substantial drip formation of wax material during burnoff of the wax material and is also a filler material which after burnoff leaves behind an easily removed residue material.  The improvement is directed primarily to a method set forth in U.S. patent 4,127,683 entitled "Method of Stacking Glass Sheets."

Abstract: ABSTRACT The present invention relates to a microprocessor control of optical components for variable magnification, the control including a bi-directional AC motor, a reference potentiometer, an analog to digital (A/D) converter, and triacs for driving the motor. The potentiometer voltage represents the present position of the optical components in the reproduction machine. The position of the optical components determines the actual magnification ratio of images. Upon selection of a particular magnification ratio, a digital position word from memory corresponding to the selected magnification ratio is compared to the optical component current position voltage converted through the A/D converter. Depending upon the error signal generated by the compare operation, a run bit is set to activate the motor in the direction to minimize the error signal and position the optical components to achieve the magnification ratio selected. In another feature of the present invention, as the optical components near the desired locations, the motor is selectively pulsed to progressively decrease the duty cycle of operation. For example, the duty cycle of operation is decreased from 100 percent to 70 percent, 50 percent, and 30 percent to slowly position the optical components and minimize inertia effects.

Abstract: Abstract A crucible for containing molten magnesium, and a process for forming the crucible.  The crucible is formed from ferritic stainless steel, and particularly type 444 stainless steel plate.  The method involves forming ferritic stainless steel plate into component parts of the crucible, while maintaining the ferritic stainless steel plate at temperatures above about 200°F. but below the "blue brittle" temperature range.  Further, the method involves special techniques for welding the crucible parts.  Specifically, the crucible parts are preheated to a temperature of 100°-150°C and are completely welded by a process utilizing multiple welding passes with a special metal inert gas shielded welding technique before any cool down of the crucible parts below 100°C is allowed.  The welds extend completely through the crucible walls, which are the thickness of steel plate, and completely incorporate the crucible parts while being essentially free of cracks.

Abstract: ABSTRACT OF THE DISCLOSURE           An  adjustable  integral  closure device for a bag includes an operating portion and an elongated closure band.   The operating portion has a main part defining a  bag-engaging  surface  and a lever member having one end pivotally connected  to the main part and  an opposite  distal  end.   The  lever member  is pivotally movable between a first position adjacent the bag-engaging surface and a second position remote therefrom.    The  device  further  includes  resilient latching means which are operative between the lever member  and the main part when the lever member is in the second position.   The elongated closure band has one end integral with one end of  the operating portion and is adapted to be fixed  at a point along its length to a fixing means provided on the device. The band extends across the bag-engaging surface to define a closed loop therewith when it is fixed to the fixing means.   Movement of the lever member from the first position to the second position serves to decrease the circumference of the loop.

Abstract: ABSTRACT      The present invention is directed to improvements to a Figal Washer System.  A Figal Washer System is a system for washing Figal five gallon syrup containers utilized in the beverage dispensing art.  The improvements to the Figal Washer System of the present invention are directed to improving the production efficiency, the Figal discharge, and the time required for routine and scheduled maintenance on the Figal washing system. The modifications which are considered to contribute to the overall machine operation are directed to improvements relating to production efficiency, which include rail and carriage modifications. A rail is installed inside the washer, beginning just beyond the loading station, for providing jam protection.  The figal container carriage has been modified to ensure that the Figal's remain in the carriages between the loading station and the first rinse station, two spring wheels are added.  A loading guide has been added to the carriage for improving the rigidity of the carriage and for guiding the loading of the Figal's into the carriage.  The two spring loaded nozzles on the carriage are fastened to a single new plate, replacing the two separate plates as previously used. To provide easier loading, the single topwheel is replaced by two independently sprung top mounted wheels.  Improve-ments relating to the discharge include a new discharge mechanism include 2 front flange mounted cylinder bolted inside a sheet metal cover with a rod protruding  through the cover.  Improvements relating to machine maintenance include new carriage bearings, a transfer valve retracting mechanism, and a rotary actuator.

Abstract: ABSTRACT     A method of separating relatively magnetic particles from relatively non-magnetic particles comprising allowing a mixture of the magnetic and non-magnetic particles to fall, under at least the influence of gravity in a three dimensional stream in a common path closely adjacent to a wall of a channel nearest the magnet which is arranged and designed to produce a strong magnetic field force in a horizontal direction, the horizontal component being greater than that of the vertical component which is less than that of gravity, the free fall of the particles being interrupted as they pass adjacent the magnet to cause them to move away from the magnet thereafter the magnetic particles move back towards the magnet whereas the non-magnetic particles are not drawn away from their diverted path.     The invention also applies to a magnetic separator having means to divert the particles away from the magnet.
