Abstract: 34                  49,612 ABSTRACT OF THE DISCLOSURE A solid-state load protection system whereby a poly-phase alternating current system is monitored ena-bling a loss  of phase  feature to be used.  A current sensing function is utilized so as to produce an output signal which is related to the current in an electrical circuit.  Attached to the current sensing function are two capacitors each having their own signal path so as to have different charging and discharging rates.  During a loss of phase condition, one capacitor discharges more quickly than the  remaining  capacitor with the  result that the voltage across the quickly discharging capacitor,  which during normal  conditions  is greater than the remaining capacitor, now becomes less than the remaining capacitor. A loss of phase sensing function detects this difference in potential levels thereby initiating a trip signal to the output function.  The output function upon receiving a trip signal causes a light-emitting diode to conduct and also  deenergizes  a  contactor  through  which  a  current source is connected to the load.

Abstract: ABSTRACT   A document handling apparatus for a duplicating machine or copier is disclosed and includes a document supply tray, a turnaround roller and the exposure platen arranged in a general horizontal configuration wherein all operating areas and separate transports are available for operator observation and jam clearances. The turnaround roller permits return of document sheets to the platen in an inverted orientation to permit copying of duplex document sheets. The rotational speed for this operation may be significantly increased relative to the processing speed of the copier and the normal feeding speeds of the document sheets from the supply tray to the platen in order to maximize throughput of the copier. For normal return of the document sheets for the platen area, the rotational speed of the roller may be relatively high compared to the document feeding speed, thereby minimizing time losses due to machine pitch spacings between document sheet changes.

Abstract: ABSTRACT OF THE DISCLOSURE           A portable seat for suspension between spaced supports is provided comprising a flexible seating member having rigid side edge members and rigid suspension members spaced outwardly from and generally parallel thereto, the suspension members and the rigid side-edge members having securing means adjacent the ends thereof, each side edge member being adjustably secured to its associated suspen-sion member by a length of rope slidably threaded through the securing means so that the spacing between the side edge members and the suspension members can be adjusted by varying the effective rope length, which effective length is maintained by preventing movement of the rope back through the securing means after the desired distance between side edge members and suspension means is achieved. For sway prevention each rope length may be threaded through the securing means to provide both parallel legs and diagonally crossed legs.  By having the ends of each rope extend through a common securing means ease of adjustment is facilitated.

Abstract: ABSTRACT     An optical focusing system is provided for accurately focusing a wafer surface, thereby enabling the production of sharp microcircuit images.  Accurate focusing is achieved despite non-parallel and non-flat wafer surfaces, despite differences in reflectivity of different portions of the wafer surface, and despite changes in environmental conditions such as temperature during system operation.      The system comprises a full aperture focus detection apparatus, a kinematic lens positioning apparatus, and a kinematic wafer chuck differential leveling or positioning apparatus.  The full aperture focus detection apparatus detects the extent to which a wafer surface is out of focus with respect to the image plane of a projection lens, and produces an amplified differential signal having magnitude and polarity indicative of the extent and direction, relative to the image plane, that the wafer surface is out of focus.  When the center of the wafer surface is to be focused and is positioned along the optical axis of the system, the amplified differential signal causes the kinematic lens positioning apparatus to focus the center of the wafer surface by moving the projection lens a distance and direction corresponding to the magnitude and polarity of the amplified differential signal.      The kinematic wafer chuck differential leveling or position-ing apparatus provides for differentially leveling the chuck at three selected off-center locations.  When a point on the wafer surface corresponding to one of these three locations is to be focused and is positioned along the optical axis of the system, the amplified differential signal causes the kinematic wafer chuck differential leveling or positioning apparatus to focus that point by raising or lowering the chuck at exactly that point.

Abstract: A Dispenser for Metering Dental Compositions ABSTRACT OF THE DISCLOSURE            A one-hand operated dispenser for metering dental compositions comprises a casing for receiving the dental composition between a forward dispensing end and a plunger which is movably mounted within the casing. The plunger is moved forwardly by means of a threaded spindle which engages with a nut disposed on the rear casing end so as to be secured against rotation and axial movement. The thus formed assembly may be inserted into two bifurcated brackets of a generally U-shaped receptacle forming part of a mani-pulating member. The spindle is guided in the one bracket so as to be axially movable and non-rotatable, while the casing with the nut is mounted in the other bracket so as to be non-displaceable but rotatable. When the manipulating member is gripped, the casing may be turned between thumb and index finger such that the spindle is pushed forwards, whereby the dental composition exits from the dispensing opening.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus are provided for loading railroad cars coupled in motion.  Prior to loading, an "empty" composite weight is obtained of the front and rear trucks of an empty selected railroad car, the rear truck of the adjacent forward railroad car with load and the front truck of the adjacent rearward railroad car. This "empty" composite weight is stored in a memory   The dynamic composite weight during loading is sensed.  A desired net weight of the load (to be loaded into the selected railroad car) is selected.  A total composite weight that is equal to the "empty" composite weight plus the desired net weight of the load is stored in a memory. The selected railroad car is loaded until the dynamic com-posite weight appears equal to the total composite weight. The actual net weight of the load is then determined by substracting the empty composite weight from the actual total composite weight.  By loading the selected railroad car in this manner, the net weight calculation will not be subject to error caused by weight transfer through couplers.

Abstract: LUBRICATING MECHANISM FOR SCROLL-TYPE FLUID DISPLACEMENT APPARATUS          ABSTRACT       A lubricating mechanism for a scroll-type fluid displacement apparatus is disclosed. A driving mechanism for an orbiting scroll comprises a drive shaft and a drive pin projecting at an eccentric location from an inner end surface of the drive shaft. An annular boss projecting from a circular end plate of the orbiting scroll receives the drive pin. Therefore, the orbiting scroll is rotatable supported on the drive pin. The lubricating mechanism includes an oil passageway formed in the circular end plate of the orbiting scroll to communicate between the interior of the boss and one of the fluid pockets located at the outer peripheral portion of the spiral elements. Lubricating oil thus flows into the interior of the boss and lubricates the bearing and other contact surface disposed in the center portion of the apparatus.
