Abstract: Abstract of the Disclosure An optical character reader for conversion of information to a machine readable code from a strip of alpha-numeric charac-ters on the face of a document.  It includes an elongated document slot along which the document may be hand guided through a pre-determined path. Optical viewing means is provided across a scan line intersecting the path of the alpha-numeric characters.  A character scanning assembly electronically generates images of each character.  Recognition processing means encodes  these images into a machine readable code.  All of the physical, optical and electronic components are contained within a compact single enclosure.  The character scanning assembly is located on a sepa-rable support frame that includes a surface adapted to be slidably engaged by the face of the document being read.  This support frame contains the viewing slot through which light is reflected from the document face.  It also rigidly mounts an array of light-responsive sensors, and an intermediate reflective mirror surface and lenses for focusing of the reflected light onto the light-responsive sensors.  Since the support frame mounts the entire optical path of the apparatus, these components can be prealigned prior to being fixedly mounted to a document guiding apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to an improved method of making a sprue bushing for injection molding and the improved sprue bushing made thereby.  The runner passage extends through a corrosion resistant inner core portion around which a helical electrical heating element is located.  A stainless steel outer sleeve extends between an enlarged front portion which provides the opening to the gate and an enlarged back collar portion which provides for connection to the heating element leads.  The space around the heating element if filled by a highly conduc-tive material such as a beryllium copper alloy in a vacuum furnace which causes the beryllium copper to fuse with the adjacent materials.  This improves the transfer of heat from the heating element to the melt and the outer sleeve substantially reduces the costly machining required to produce the finished product as well as provides additional strength.  In one embodi-ment, wells extending into the front portion are filled with the highly conductive material which increases heat transferred to the gate area.  A thermocouple may be located in  one of the wells to monitor the transfer of heat to this area.

Abstract: ONE-PIECE RAZOR HANDLE                  ABSTRACT OF TECHNICAL DISCLOSURE         A one-piece razor handle molded from resilient plastic has spaced-apart opposing side walls joined at an intermediate location by a neck.  The walls diverge upwardly from the neck into upper portions for gripping a blade cartridge, and extend downwardly to a spacer that extends between the lower portions of the wall.  The lower portions of the walls, between the neck and spacer, are resiliently squeezable.  The neck acts as a fulcrum so that the upper portions pivot outwardly as the lower portions are squeezed inwardly. A base joins the bottoms of the walls extending past the spacer.

Abstract: ABSTRACT OF THE DISCLOSURE          A firing pin block for a firearm of the type having a rotary breech bolt, a reciprocating bolt carrier, complementary locking lugs formed on the bolt and barrel to releasably secure them together, and cam means drivingly connecting the bolt and bolt carrier for opening and closing the bolt  The firing pin block positively prevents discharge of the firearm at any time when the bolt is unlocked.  It does not rely on the presence or good condition of any separate parts, but instead coordinates the cam-actuated rotary operation of the locking lugs with relative longitudinal displacements between the bolt and bolt carrier, to cause the latter to block an enlarged abutment formed on the firing pin whenever the bolt is unlocked.

Abstract: ABSTRACT            A system is provided for the separation into and the identification of classes of events wherein each of the events is represented by a signal vector comprising the signals s, sz...,sj...,sN.  The system comprises a plurality of assemblies, each of the assemblies in-cluding a matrix of junction elements for respectively receiving as inputs the different respective signals of a vector.  The junction elements provide a transfer of information Aijs,; i.e., the product of the transfer function of the element and the signal input applied thereto.  The information transferred by the junction elements is summed in each assembly.  In the training mode of operation information summed in each assembly is applied to a scalar multiplier and the resulting information is in turn applied to a threshold stage which is actuated to produce an output if the input applied thereto attains a prescribed value.  Con-currently, the summed outputs of the junction elements are fed back to these elements to modify their transfer functions.  The outputs of the threshold stages are finally processed for identification of the  classes of events.  In the training mode of operation the occurence of ambiguous and undesired identifications cause feedback to the pertinent scalar multipliers to decrease their multiplication factors.  Such decreases are made until no further ambiguous and undesired identifications occur.  At the completion of the training for a particular group of related classes of events, the values of the transfer functions of the junction elements as well as the multipliers have attained final desired values.  Then, in the trained mode of operation for the separation and identification of the group of classes for which the system has been trained, the feedback to the junction elements, and the scalar multipliers with their feedback arrangements are not employed or are removed.

Abstract: ABSTRACT OF THE DISCLOSURE:      A water recovery system in which drain water from appliances, sinks and bathtubs are conserved in a storage recovery tank for treatment and reuse as a water supply for toilets.  The drain water is directed through an outlet to flow over a pivoted grate that is mounted above the top opening of the storage tank, with the grate formed of spaced inverted T-shaped ribs and normally held at an acute angle, such as ten degrees, to the horizontal plane by a spring so that debris retained on the grate is washed dia-gonally downwards off the top surface of the grate to fall off the lower end of the grate into a debris-collection and tank overflow unit.  The drain water, itself, falls between the grate ribs into the storage recovery tank.  The grate is linked to an outlet valve leading from a liquid chemical storage tank so that liquid treatment chemicals in the chem-ical tank are released into the storage tank during periods of drain water flow onto the grate, when the grate is pivoted to a greater angle, such as twenty degrees, to the horizontal by the weight of drain water flowing on and through the grate.  The grate is also linked to a first float which prevents the grate from opening the release valve of the chemical tank when the storage tank is full.         A second float in the storage recovery tank admidst fresh water into the tank, when the tank level falls below a pre-set minimum.  A pump operated by a pressure switch automa-tically supplies water to the toilet supply line upon demand.

Abstract: ABSTRACT OF THE DISCLOSURE      A process and apparatus for forming fibers from attenuable materials, such as molten glass, by attenuating streams of glass from the bottom of a bushing wherein the bottom has downwardly presented wall portions at upper and lower levels.  According to the disclosure the upper or lower wall portions are formed into a series of elongated bosses each containing at least one row of cells termed alveoles, each alveole having a multiplicity of orifices extending through the lower wall portion of its boss. Filamentary material is manufactured by drawing at least one filament from each alveole independently of each other alveole regardless of whether or not the material has flooded the bottom surface of any boss.  In one embodiment shallow transverse grooves in the lower wall portions of the bosses separate the orifices of one alveole from the orifices of adjacent alveoles so that flooding is confined to a single alveole.  Controlled cooling permits the selective drawing of one or a plurality of filaments from the alveoles.
