Abstract: OPTICAL APPARATUS FOR SELECTIVELY PRODUCING          RIPPLED MESSAGE IMAGES IN AREAS OF SPECULAR          SURFACED PHOTOPLASTIC FILM AND ERASING SUCH                IMAGES FROM SUCH AREAS FOR REUSE ABSTRACT    Optical camera and image processing apparatus for selectively producing rippled message images in frame areas of specular sur-faced photoplastic film by image patterned electrostatic charge and heat deformation.  Image bearing light beam is projected through an objective lens unit and focused upon a transverse photo-plastic film supporting means.  Such supporting means includes a lateral platen located back of a section of said film which margins a specular surface area of such a film frame.  Means intervening the objective lens unit and the position of a film section when supported upon the platen provides an optical aperture.  This film supporting platen has an opening opposite the optical aperture whereby the back of the film opposite its specular surface area is accessible.  A heatable metallic block is movably mounted so that it can be moved forward into the platen opening for contact of the accessible area of the back of the film to effect conduction heat softening of this film area that is located between the optical aperture and the platen opening for producing such a rippled frame area.  Grounding means is associated with the film section when supported upon this apertured platen, and electrostatic charging means imposes upon the platen a relatively large electrostatic charge differential which causes the platen supported film area to be snugged to the platen.     Between the film supporting means and the objective lens unit is provided means for producing and directing forward to the platen supported area of the film an electrostatic charge.  It is preferable to provide between the objective lens unit and such electrostatic charging means a shutter mechanism which may be open-ed to pass the image supporting beam onward to the supported film area and to terminate such beam passing with a discontinuance of the application of the electrostatic charging action.    Various forms of optical apparatus for using specular surfaced photoplastic film to bear or bearing rippled message images in frame areas thereof may be provided which are to handle such film in a form having a conductive substrate below its upper heat-softenable and image rippleable emulsion layer serving as an electrostatic grounding means, such apparatus will include platen means having a lateral film supporting surface with an area of the latter contacting the lower side of an area of such film, and means imposing a relatively large electrostatic charge differential upon said platen to cause the area of said film that is in contact with said platen  to be snugged to the latter by electrostatic charge adherence.

Abstract: SUPPORT ASSEMBLY FOR FUSIBLE ELEMENT         OF A HIGH VOLTAGE FUSE           ABSTRACT:  A support assembly for a helically wound fusible element of a high voltage fuse is fabricated from two identical pieces of insulating material that are formed with mating center slots so that the pieces can be reversed and joined one over the other along the slots to form a "x" shaped support member.  Finger projections having recesses for supporting a fusible element are formed along the edges of the pieces in such a positional relation-ship that when the the pieces are joined together, the recesses are positioned to form the required helical path for the fusible element.         A metallic terminator member may be mounted at each end of the support member to position and mount the support member within the fuse in a fixed position.  The terminator members includes a center keyed opening that receives the support member and positions and retains the support member.  A wire retainer can be used to engage grooves in the ends of the support member that extend through the keyed opening to lock the terminator member to the support member.

Abstract: Abstract of the Disclosure The invention relates to an optical reading device,for the read out of data carried by a reflecting support, wherein the source is a non-polarized laser of which the exit surface is reflective ; the optical noise due to the reflection of the incident wave at the support is partially suppressed by inser-ting between the last partially polarizing and/or birefractive element and the data carrier a quarter wavelength plate which optically decouples the incident wave and the return wave. The optical noise is thus limited to the beats between the incident wave and the return wave reflected a second time by the support.

Abstract: ABSTRACT     Variations of current gain from element to element in a phototransistor array are eliminated by covering the array with an opaque mask and etching openings in the mask over each phototransistor based upon an area reduction factor (ARF).  The area reduction factor for an opening is equal to (Im/Ix)1-n where n is a constant definitive of the change in beta of a phototransistor in the array over a given range of collector currents; Im is the minimum collector current measured for the array and Ix is the collector current for the phototransistor beneath the opening.      Based upon the ARF's, the openings etched in the mask or cover initiate uniform current form each phototransistor element when uniform light flux is directed on the array.      The process of fabricating the array comprises measuring the collector current for each phototransistor element at a given uniform light flux; determining the element with minimum collector current in the array; calculating the ARF for each phototransistor to achieve a uniform current response from the array; coating the array with an opaque cover, and etching the cover at each phototransistor based upon the ARF.

Abstract: SCALE OPTICAL DETECTOR WITH SPRING CONSTANT VARIATION COMPENSATOR                  Abstract of the Disclosure An optical detection system for a spring scale includes an apparatus for generating a moire interference fringe pattern and detecting the pattern movement to measure scale tare deflection and thereby determine the load weight.          One of a pair of ruled parallel grating sets is fixed while the other is mounted to the tare structure in alignment with the fixed set.  A lamp projects the interference pattern upon a photodetector array.  The placement of a load upon the scale deflects the tare structure which results in a linear movement of the projected fringe pattern across the photodetector array and the resultant sequential generation of weight indicative signals.  To compensate for variations in the spring constant of selected scale springs, the linear tare deflection required to provide movement of a given number of interference fringes past a reference is adjustable.          This adjustment of effective spring constant is achieved by varying the angle of the gratings of the movable grating set.

Abstract: Abstract of the Disclosure The present invention relates to a process in which aqueous solutions and suspensions of solid particles, even those containing less than one percent of organic materials, may be combusted with air, oxygen, or their mixtures in a process which provides for preheating in countercurrent batches of the raw original liquid by either open (direct contact) or closed (heat transfer surface) condensation of steam generated by multiple flash evaporations which cool earlier batches of hot liquid after the wet combustion.  Excess heat may often, be with-drawn from the process for power generation or other use as high pressure steam, with or without combustion gases and other non-condensibles.  No pumps are necessary, liquid batches are pressurized by steam generated in the flash evaporations for which only one pressure vessel is required instead of the many in the continuous processes.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus for energizing a digital display to give a numerical representation of torque applied to a rotational workpiece, such torque preferably being supplied by an electronic torque wrench.  In one embodiment, applied torque is sensed by variable resistors responsive to mechanical strain in a flexure element in the head of the wrench.  The variable resistors are connected in a bridge circuit which yields an electrical analog signal when the bridge is unbalanced due to mechanical strain in the variable resistors.  The electrical analog signal is tracked and converted into a digital equivalent by a servo-type feed-back circuit.  Each iteration of the feedback circuit generates a counting pulse which is registered on a set of binary coded decimal (BCD) counters connected in cascade.  The outputs of the BCD counters are displayed on light emitting diode displays on the wrench handle. Overrange, underrange, and low power in-dicator means and power strobing means are also disclosed.
