Abstract: Abstract of the Disclosure An apparatus for testing a sample by means of luminescent reaction to detect reactive materials therein. A ribbon or tape of filter material is provided to filter the sample and to carry the residue to a reaction position. A second ribbon may be provided to carry a reagent to the reaction position.  Both ribbons are brought into mutual contact in a region between two photodetectors, which thereby detect the resulting luminescent reaction to provide an indication of the quantity of reactive material present in the sample.   Alternatively, the reagent may be placed directly on the filter ribbon.  A single photodetector may be used. An improved pinion roller advances the ribbon of filter material in a reliable fashion.

Abstract: Abstract of the Disclosure Relative translational movement between a pair of X-ray apparatus components is selectively arrested by a bidirec-tional lineal lock structure including an elongated locking rod carried by one of the components and a locking unit carried by the other component.  The locking unit is movable along the locking rod and includes two sets of balls which selectively engage the peripheral surface of the rod.  Two clamping systems normally wedge the balls into clamping engagement with the peripheral surface, preventing relative component movement.          A pair of electromagnets are operative, when energized, to bias the clamping systems toward release positions to permit relative component movement.  Either of the electromagnets may be selectively energized to permit unidirectional relative movement between the components.  An energizing circuit is provided for briefly reversing the polarity of the electromag-nets immediately before they are de-energized, to facilitate re-establishment of the clamping engagement.

Abstract: ABSTRACT OF THE DISCLOSURE       An improved process for separating normal paraffins from a feed stream containing a mixture of normal paraffins, isoparaffins and aro-matic hydrocarbons to produce a normal paraffin product stream having a reduced concentration of contaminant aromatic hydrocarbons.  The general process comprises the steps of contacting the feed stream with an adsorbent comprising a crystalline aluminosilicate wherein normal paraffins are adsorbed within the pores of the adsorbent and contaminant araomatics are adsorbed on the surface of the adsorbent and subsequently contacting the adsorbent with a desorbent material to remove both ad-sorbed normal paraffins and contaminant aramatics.  The improvement re-sides in using a two-stage desorption step in which a first desorbent material contacts the adsorbent and removes surface-adsorbed aromatic contaminants and then a second desorbent material contacts the adsorbent to remove normal paraffins adsorbed within the pores of the adsorbent.

Abstract: ABSTRACT OF THE DISCLOSURE A remote control brake system for a railway train in which the caboose is equipped to receive radio signals trans-mitted from the locomotive indicative of a brake application initiated by two locomotive engineer.  The received radio signals are interpreted and converted into control signals which operate magnet valves via which fluid pressure in an equalizing reservoir on the caboose is reduced an amount depending upon the duration of the transmitted brake applica-tion signal.  The equalizing reservoir is charged in the absence of a brake application signal by the pressure in the brake pipe and serves as the control pressure for operating a self-lapping relay valve which is arranged to exhaust brake pipe pressure responsive to a reduction of pressure in the caboose equalizing reservoir. The train brake pipe pressure is thus reduced concurrently from the front and rear ends when a brake application is initiated to provide faster and better synchronized response of the train brakes.  Since the train brake pipe is charged from the front end only, a pressure gradient exists during charging.  This so-called false brake pipe gradient is detected by a special circuit at the locomo-tive to prevent a brake application signal from being ?rans-mitted to the caboose until the pressure gradient in the brake pipe equalizes, thereby preventing undesired release of a brake application by reason of the pressure gradient flowing toward the rear of the brake pipe after the brakes have applied.

Abstract: ABSTRACT OF THE DISCLOSURE         The object of the present invention is to provide a process for the manufacture of soluble organic copolymers, which give non-tacky, water-resistant and elastic films on very diverse substrates or are suitable as binders for pigments, paints and non-wovens, and for the use of these copolymers as a binder component, the sheet-like structures, which can be manufactured from these polymers, having, however, properties which are considerably improved in various respects.  In this connection, a lacquer, which contains the new soluble organic copolymers in combination with organic polyisocyanates and is applied to a metallic substrates, cures, after drying in air for three to four days at temperatures of about 20°C, in such a way that the film does not swell under the action of water and also cannot be removed mechanically by scraping, even if the film is briefly exposed to water at temperatures of 50 - 70°C.        The binders exhibit a good pigment-binding capacity and also possess good resistance to weathering; these binders are employed mainly as automotive lacquers for final lacquering or as car touch-up lacquers.

Abstract: ABSTRACT OF THE DISCLOSURE     There is provided a thermoplastic adhesive which consists of a reaction product of tall oil pitch with an organic anhydride, such as maleic anhydride, saponified with a multivalent metal hydroxide, such as calcium hydroxide.  The reaction between tall oil pitch and the anhydride is preferably carried out by heating in the range of 120°C to 200°C for one to eight hours.  The saponification is either complete or partial and is carried out by reacting the adduct obtained from the reaction of the tall oil pitch with the anhydride, with a suitable amount of the multi-valent metal hydroxide at about 200°C for ten to thirty minutes.          The produced adhesive is solid at room temperature and can possess, depending on the formulation, either high binding strength or pro-longed pressure-sensitive character.

Abstract: Abstract of the Disclosure A coil is wound on a hollow plastic bobbin and mounted in a U-shaped ferromagnetic frame, there being a pair of aligned bosses on opposite sides of the bobbin bore at one end thereof fitting into cooperating slots in the frame.  A ferromagnetic core is axially movable with-in the hollow bobbin and is urged away from the bottom of the frame by a leaf spring   A compact plastic housing covers the bobbin, coil, and the upper portion of the frame, and electric terminals, mounted in pockets at the top of the bobbin, project through slots in the housing to the exterior.  Portions of the bobbin are extruded into openings in the base of the terminals to hold them in place, and a pair of tabs on the bobbin interact with slots in the housing, and posts on the inside corners of the housing form abutments to prevent over-insertion of the tabs in the slots.  A hook on the bottom of the frame is shaped to be engageable with an opening in external support elements of differing thickness to facilitate in-stallation.  The coil contains a relatively fine gauge wire which acts as a fuse if the buzzer is energized beyond a predetermined time period.

Abstract: CONTROLS FOR SEMICONDUCTOR WAFER ORIENTOR                       ABSTRACT    This specification deals with electro-optic controls for stopping and orienting of a semiconductor wafer being transported along a track on an air film.  At one or more locations along the track the characteristics of the air film are changed by electronic controls responding to optical pickups sensing the position and orientation of a semiconductor wafer entering the particular location on the air film to first stop the wafer in the general proximity of the location, then center the wafer in the location and after the wafer is centered, quickly rotate the wafer until it assumes the desired orienta-tion.  All this is done without edge contact of the wafer by any solid objects.
