Abstract: ABSTRACT     An internally illuminated sign structure comprising a housing enclosing a plurality of lamps and having an open front in which is supported a windbalanced sheet of translucent film bearing the sign message.          The housing has passages communicating with the laminar air flow region about the housing to the interior to allow air to enter the structure, which air develops a pressure equal to that developed by the wind component striking the face of the film to afford a static balance on the  front face of the film.  The passage to the interior of the housing has a total cross-sectional area at the plane of the film of at least 5 times the combined area of any other openings in the housing which do not receive the force of the winds against the front face.  Other openings in the housing may be drain holes for moisture, air leaks around access openings etc.

Abstract: Abstract of the Disclosure Cyproheptadine derivatives substituted with a trifluoromethylthio or trifluoromethylsulfonyl group in one of the benzo rings and having a hydroxyalkyl or cycloalkyl-alkyl group on the piperidine nitrogen are potent anti-psychotic agents, with a low propensity to induce extra-pyramidal side effects that are experienced with most major tranquilizers.  The tranquilizing activity is pre-dominantly in the levorotatory enantiomers, whereas the dextrorotatory enantiomers have anticholinergic activity.        Each enantiomer is useful as a source of the other by racemization.  The novel compounds are prepared by treat-ment of the corresponding iodo or bromo compound with bis-(trifluoromethylthio) mercury and copper powder.

Abstract: ABSTRACT OF THE DISCLOSURE           A techniqu  for producing measurements of physical characteristics of subsurface media near a borehole penetrating the earth is disclosed that uses multiple transducers positioned along a borehole tool.  A number of transducers of a first type, such as transmitters, are separated from each other along the tool by a preselected separation, and a number of transducers of a second type, such as receivers, are separated from each other by the same separation and are positioned on the tool at a preselected distance from the transducers of the first type. The technique contemplates the use of appropriate circuitry for producing measurements, using different combinations of trans-ducers, of physical characteristics of the subsurface  media at different positions along the borehole.      Furthermore, different combinations of measurements produced at different borehole positions may be compared or combined to produce improved measurements that are compensated for borehole effects and other errors.

Abstract: ABSTRACT           Photographic apparatus has a film advance mechanism that advances the foremost film unit from within a cassette of stacked units by a major distance far longer than an access slot conventionally provided on the cassette for a short, index-like film advance.  In a self-developing camera, the long advance can move an exposed film unit from the image surface to remotely-located spread rollers that initiate film processing.          The advance mechanism engages the film unit in a manner that avoids conventional structural limitations on the length of the advancing travel.  One embodiment introduces a pick arm, which drivingly engages a back edge of the film unit, into the film cassette under a marginal flange;  the arm is free to travel inside the cassette along a major portion of the cassette length.  Another embodiment successively indexes the film unit forward through the conventional access slot of the cassette and engages an accessable frontal margin of the unit to pull it further along the path of advance.

Abstract: METHOD AND APPARATUS FOR BLOW MOLDING               ABSTRACT OF THE DISCLOSURE        A method and apparatus utilizing preform and final blow molds for forming molecularly oriented thermoplastic articles.          According to the method, an extruded tubular parison is positioned within the pre-form blow mold and blown to a pre-form configuration.  The blown pre-form is then conveyed, while sus-pended from a moveable carrier, through a thermal conditioning chamber and the temperature of the pre-form is adjusted to with-in the range for molecular orientation.  Next, the thermally conditioned pre-form is conveyed by the moveable carrier to a final blowing station where the pre-form is blown to the con-figuration of the final article.  In a first disclosed embodiment the carrier is a blow pin which is inserted into the tubular parison at the pre-form molding station prior to the first mold-ing operation.  In the second embodiment, the carrier is a tubu-lar projection telescopically inserted into the blown pre-form prior to entry of the pre-form into the thermal conditioning chamber, and the pre-form is blown to its final shape by a blow tube inserted through the carrier.  In both embodiments, the carriers are used to convey successive pre-forms in a contin-uous molding operation.

Abstract: APPARATUS FOR DEVELOPING LATENT IMAGES                 Abstract of the Disclosure Apparatus for liquid development of latent photo-graphic or electrostatic images on a support material or film comprises a member against which the support material is clamped.   The member has a chamber that is open to the support material and which may selectively be interconnected to a source of air under pressure and to a reservoir con-taining development liquid. As developing liquid is being introduced into the chamber, a flow defining surface moves to a position adjacent to the image-bearing material to form a flow passage for the liquid over the material.  An electric potential may be applied to the flow defining surface to provide a development electrode.  After development, drying air is introduced into the chamber to remove, squeegie and carry away any fluid remaining on the surface of the support material.  The apparatus is arranged to wipe the flow defining surface clean of development liquid before the drying period and to remove that surface from exposure to the drying air.   After drying, a member which forms a restricted-flow air passage across the support material is drawn over a wipe surface to clean the member of development components.

Abstract: SLACK ADJUSTER ASSEMBLY            Abstract A slack adjuster assembly for brakes includes a slack arm, ratchet wheel and pawl carrier all rotatable about a common axis in unison and relative to one another.  The parts rotate in unison during normal operation when the slack arm rotates back and forth in brake apply and brake release directions.  When an adjustment is required due to brake wear, the slack arm will overtravel in the brake apply direction.  When overtravel occurs, rotation of the pawl carrier with the slack arm and ratchet wheel through the overtravel portion of the stroke is stopped to effect rela-tive rotation between the pawl carrier and the ratchet wheel.  Upon return of the slack arm in the brake release direction from an overtravel stroke, the pawl carrier is rotated relative to the slack arm and rotatably drives the ratchet wheel relative to the slack arm.

Abstract: ABSTRACT        An improved bed spring unit assembly is provided in which a preformed grid of perpendicularly intersecting wires, spaced apart and welded together, are tightly joined together as well as to the top turns or rings of a number of coil springs by inverted U-shaped wire clips detached and fed preferably automatically from a cemented group of such clips much like conventional staples.  An upper grid wire is arranged to span each ring diametrically while a pair of lower wires parallel to each other are arranged as respective opposed chords of the ring each spaced inwardly at its weld from the adjacent perimeter of the ring just enough to permit the insertion of a clip leg or legs at an inward and downward slant into the space between the perimeter of the ring and the chord portion of the other wire while straddling the spanning wire.  The legs are then bent outwardly and bent tightly around the ring so far as is necessary to press one or both into a wrapped position around the ring and to carry the wires down into pressed contact with the top of the ring thus making an indent in the chord. A second similar clip similarly connects the other chord and the spanning chord with the ring turn at the opposite point of the ring.  The invention avoids the necessity for secondary operations such as welding or crimping to join the rings and the grid wires.
