Abstract: CONTROL CIRCUIT FOR ELECTROSTATIC COPYING MACHINE              Abstract of the Disclosure An electrostatic copying machine of the type which includes apparatus for forming a developed graphic image on, for example, a sheet of paper, and includes a heatable enclosure space within which the image bearing paper is disposable and apparatus for heating the space to bond the image to the paper; is provided with a circuit for controlling operation of the machine in con-sideration of the temperature of the enclosure space.  The circuit includes a switch for energizing the forming and heating apparatus from a suitable source of electrical power, and a switch for actuating the energized forming apparatus.  In addition, the circuit includes apparatus for sensing the temperature of the space and disabling operation of the actuating switch, and thus the forming apparatus, until the enclosure space heats up to a predetermined graphic-image-bonding temperature level.  Further, the circuit includes apparatus for preventing disablement of the aforesaid actuating switch until the actuated forming apparatus has been thereafter deenergized; and includes a lamp for visually signalling whether or not the enclosure space has heated up to the predetermined temperature level.

Abstract: CYLINDRICAL BRUSH WITH   STUB SHAFT SUPPORT     ABSTRACT OF THE DISCLOSURE    A separable stub shaft connection for a rotatable surface treating member, such as a brush, having a tubular hub.  The connection includes a stub shaft having a preselected length thereof projecting into one end of the hub.  A pair of diamet-rically opposed but axially spaced bearing areas create a secure engagement between the hub and stub shaft when bolted together.          Appropriate clearances are provided to permit the shaft and hub to be angularly tilted through at least a limited extent relative to one another so that the stub shaft and hub can be relatively axially displaced when the hub is to be mounted on or removed from the stub shaft.  The other end of the hub is  mounted on a further stub shaft connection which permits the other end of the hub to be moved transversely relative to the stub shaft.  For this purpose, the other end of the hub has a separable arcuate sector which extends through an angle of approximately 180°.

Abstract: INVENTOR                  C. Stewart GENTSCH                  TITLE SNAP ON TOP PLATE ASSEMBLY                ABSTRACT OF THE DISCLOSURE   The specification discloses a snap-on top plate assembly for a roller chain.  The assembly comprises an inside saddle in the shape of a channel, an outside saddle in the shape of a channel shaped to fit over the inside saddle, and a top plate.  The inside saddle has holes through its legs shaped and positioned to accept the outside ends of the pins in a link of roller chain when the link is positioned within the inside saddle.  Three embodiments are disclosed. In two of them, the legs of the inside saddle are generally flat; in the other, the legs of the inside saddle are bowed inwardly.    The top plate assembly is used to guide the roller chain through slot ways of a surface such as a table and thus confines the chain travel in close proximity to this surface.  In such environment the top plate may act (when there is roller chain travel) as a conveyor of materials over the surface as is commonly required in the packaging industry or other materials handling applications.  In such applications, each top plate articulates, and is driven by a single chain link of the roller chain.  This facilitates chain link replacement.

Abstract: ELECTRIC ARC WELDING POWER SUPPLY                       ABSTRACT      A three phase electric arc welding power supply using SCR rectifiers for output control which has improved output characteristics, fault protection and current and voltage controls.  The main power transformer is connected in a double wye with the neutral points interconnected by a pair of inde-pendent interphase inductances in series, the mid point forming one of the output terminals.  Increased phaseback of the SCR's may be effected without the use of additional inductance in the output circuit.  The fault protection circuit has a time-current trip curve closely approximating the time-current overload curve of the SCR's whereby the minimum size SCR's for a given maximum current output is obtained.  The control circuit is fast responding and gives either:  constant voltage output; or variable voltage, constant current output with both line voltage compensation and with increase of current when the arc is shorted and the arc voltage drops below a predetermined amount.  Improved firing circuits for the main and pilot SCR's are provided.

Abstract: ABSTRACT OF THE DISCLOSURE To improve the quality of copies made on an electrostatic reproduction machine, a post exposure pre-development corona generating device is used to treat an electrostatic latent image on a photoreceptor.  The device deposits a treating charge onto the latent image of the same polarity as the latent image the treating charge being of a magnitude sufficient to lower the charge contrast between the background of the latent image and undesirable low density image areas, but not sufficient to detrimentally affect other areas of the latent image.  The treating charge may be varied upwardly or downwardly to obtain the desired result, but as it is varied, an electrical bias applied to a developer is simultaneously varied in the same direction so that the magnitude of the bias is always a substantially constant amount above the magnitude of the charge on the background of the latent image.

Abstract: DEVICE FOR THE PRODUCTION OF GRANULATED PRODUCTS FROM SOLUTIONS OR SUSPENSIONS OF FOOD SUBSTANCES         Abstract of the Disclosure The present invention relates to food industry equipment.  It is particularly adapted for use in the producti-on of granulated food products, preferably imitation soft caviar.  The device comprises a heated chamber for keeping said solution or suspensions under pressure, which has through holes drilled in the chamber bottom along a con-centrical circumference. Tightly pressed against the bottom from inside is a rotatable disk with through holes which are to match the holes in the chamber bottom during rotation of the disk.  A vessel is installed under said chamber to contain a forming liquid and to form granules for the solutions or the suspensions fed into the vessel via the holes in the bottom of said chamber. This vessel is cooled and accommodates a pipe for feeding the forming liquid to the vessel and a pipe for taking the forming liquid out of the vessel together with formed granules.  The vessel jointed to the chamber bottom through the medium of a heat-insulating spacer with nozzles coaxial with the holes in the bottom is actually a tubular heat exchanger, whose tubes communicate with the holes in the chamber bottom via the nozzles.  Each nozzle concentrically protrudes from the spacer into the /   upper end of the respective tube with an annular gap, thus allowing the tubes to communicate with each other and with the forming liquid feeding pipe. The granules forming device of this design makes it possible to retain the food value of formed granules and to raise the efficiency of the device considerably.

The piezoelectric transducer is preferably an arcuate sector of a cylinder having an angle no greater than 180° with its mean radius, wall thickness, and its arcuate angle selected so that the arcuate sector vibrates only in a selected symmetrical mode at a selected resonant frequency when a voltage is applied at that frequency.  The length of the transducer is chosen to be longer than the length of the linear array of nozzles so that the periodic pressure waves produced in the ink cavity by the transducer vibrating at the selected resonant frequency will have substantially the same amplitude at the entrance of each of the nozzles to form droplets of substantially uniform size and at substantially the same break-off point.  The applied voltage selected is that which is necessary to produce uniformly satellite free droplets from the array of ink streams.
