Abstract: ABSTRACT A single facet wobble free light scanner which eliminates the effects of wobble caused by bearing inaccuracies or other mechanical factors. A pentaprism, pentamirror, right angle prism or right angle mirror monogon 30 is rotated about an axis passing through its sides and through the axis of the applied light beam 8. By reflections off of two mirrored surfaces 22, 24, the output light beam 28 creates a plane of light. When, or if, the pentaprism 30 wobbles about the rotational axis, the effects of the wobble are eliminated because via the internal reflections of the pentaprism, the output light beam 28a is parallel to the original output light beam 28, the parallel light beams 28, 28a being focused onto the scan surface by external optics.

Abstract: Abstract An expresso coffee maker for use in a microwave oven.          The water is stored in a microwave transparent reservoir or container which is adjacent to the pot.  The pot and reservoir are coupled in a fixed spacial relationship by a collar.  The collar includes a strainer which presses against a layer of coffee grounds when the collar is rigidly secured to the reservoir.  The compressed coffee grounds in combination with the strainer form a pressure resistant seal over the opening of the reservoir. The water in the reservoir is heated by microwave energy.  The pressure rises to a level sufficient to force steam and water through the coffee grounds into the pot.

Abstract: Abstract Circuitry controlled by a series of switch actuations per a preselected switch code provides a control signal.  A plurality of flip-flop circuits are connected for series operation.  A plurality of switches in excess of the number of digits in the code are available to provide an actuating signal for a flip-flop circuit.  A time delay provided between successive flip-flop circuits enables a given switch to be used more than once for a switch code.  Automatic resetting of the last flip-flop circuit at which the control signal is provided allows the control signal to be repeated one or more times before all of the flip-flop circuits are reset. A time delay circuit at the first flip-flop circuit provides for automatic reset of the circuitry.  Each switch not connected to a flip-flop circuit as a digit of the switch code will, when actuated, reset the circuitry.

Abstract: AN IMPROVED SELF-ENERGIZED SYNCHRONIZER                   Abstract of the Disclosure An improved self-energized synchronizer for bringing two rotatable members which are aligned about a common axis into synchronization.  The synchronizer includes a body member carried on the first rotatable member which in turn engages with an annular shifter collar.  Positioned adjacent to the shifter collar is an axially movable annular blocking ring having a frictional surface.  Situated on the other side of the blocking ring, opposite the body member, is a drive collar which is rotatably fixed to the second rotatable member.  The improvement to the synchronizer includes a frictional disk and a self-energized mechanism for transferring frictional torque between the first and second rotatable members.  The self-energized mechanism is positioned for engagement with the blocking ring, while the frictional disk is positioned between the drive collar and the self-energized mechanism.  As the operator axially moves the shifter collar, the blocking ring is brought into contact with the self-energized mechanism, and a portion of the mechanism is axially forced into contact with the frictional disk.  This contact causes the frictional disk to assist in decreasing the relative rotation between the first and second rotatable members once the self-energized mechanism frictionally engages the blocking ring.

Abstract: ABSTRACT OF THE DISCLOSURE    A system is provided for predicting when the failure of a rotating machine tool or part is imminent or when a tool is worn.  The system includes a transducer for producing an output related to the workpiece vibra-tions caused by the machine tool and an analog comparator which compares this output with a threshold signal related to the normal operation of the tool and established by a microcomputer which determines whether further signals which exceed the threshold are produced during each of a predetermined number of subsequent time intervals related to the rotational speed of the tool.  If so, a "failure" signal is produced which may be used, for example, to cause retraction of the tool.

Abstract: IMPROVEMENT OF MOTION PICTURE IMAGE QUALITY    ABSTRACT    Motion picture film is photographed with standard spherical lenses, exposing in the camera the full 35mm aperture, giving in the 1.66:1 ratio a negative image area effectively 75% larger than that of the standard 1.85:1 flat wide-screen format. The frame on the ground glass is centered on the film centerline. The negative is optically printed onto anamorphic release prints employing the standard 2:1 lateral compression ratio, bypassing the problems of flat wide-screen projection, such as dim and grainy images, shallow depth of focus, and unpredictable framing. The preferred embodiment of the invention will use the 1.66:1 aspect ratio. The centerline of the print has an image offset to the standard ACADEMY*centerline, with the height of the frame on the ground glass printed to the height of the anamorphic frame, and with unused area on the top and on the sides printed with an opaque border. Similar printing can be done using as original material 35mm film photographed with the frame on the ground glass centered on the Academy centerline; 16mm film photographed in the SUPER 16*  format; or high-definition videotape.

Abstract: Abstract of the  Disclosure A gas laser with plasma chamber that can be quickly replaced by unskilled personnel. Plasma chamber can be replaced without need for optical realignment, one section of a mating mechanical coupler is secured to the non-conductive envelope of the demountable plasma chamber and is positioned in a predetermined spatial and angular posi-tion with respect to the electrodes, optical windows and the optical axis of the plasma chamber. The positioning of the mechanical coupler with respect to the electrodes, the windows and the optical axis is identical for each of the interchangeable plasma chambers. A separate base is pro-vided with the other section of the demountable coupler fixed in a precise predetermined spatial and angular posi-tion with respect to a pair of mirrors mounted on the base. When a plasma chamber fails, it is easily replaced by merely disconnecting the old chamber from the base and inserting the replacement.  The predetermined positions of the two coupler sections, one with respect to the elec-trodes and optical axis of the plasma chamber and the other with respect to the two mirrors, precisely locates the replacement chamber in position with sufficient accuracy to produce laser oscillations without elaborate adjustment.

Abstract: ABSTRACT OF THE DISCLOSURE            Disclosed are differential rate screening processes and ap-paratuses for continuously screening undersize particles in different size classes to different degrees of incompletion to provide a product having a preselected distribution of particle sizes substantially different from the distribution of particle sizes in a feed of particulate material.  An in-put stream of feed material is introduced onto a screening member having apertures of sufficient size to pass a plurali-ty of size classes, and is separated into at least a throughs stream and one other stream by causing undersize classes to pass through screen apertures and into a throughs stream in proportions relative to one another substantially different from the proportions of the same undersize classes relative to one another in the input stream. The overs, throughs or both from one rate screening member may be introduced as an input stream onto another rate screening member.  A suffi-cient population of undersize particles are provided in each undersize class and differentials between relative propor-tions of undersize classes in an input stream and relative proportions of undersize classes in a throughs stream are controlled so as to provide a product having substantially the desired particle size distribution.  Various means are provided for causing differentials between relative propor-tions of undersize classes in an input stream and relative proportions of undersize classes passing through a screen-ing member and into a throughs stream, and for controlling these differentials.  An output stream from one rate screen-ing member may be blended with an output stream from another rate screening member and at least a portion of an output stream from one rate screening member may be recycled to a crusher and then sent to the same or a different rate screen-ing member.
