Abstract: MINIATURE FOUR-WAY VALVE                  ABSTRACT OF THE DISCLOSURE     A miniature four-way valve, particularly for the con-trol of a pressurized gas, such as air, constructed and arranged so that it can be made in small sizes without excessive expense while being reliable, sturdy and resistive to damage.  The valve includes a housing having ports formed therein which accommodate conventional conduits of rather large size, which ports communi-cate with a central passage containing therein a slidable valve plunger of extremely small size.  The inlet port communicates with a chamber disposed in surrounding relationship to the valve plunger, which chamber is defined between a pair of op-posed tapered walls having a concave configuration.  These walls function as valve seats and coact with a resilient seal ring secured to the valve plunger for creating a sealing engagement similar to a poppet valve.  The shifting movement of the plunger, which causes the seal ring to be shifted into sealed engagement with one of the opposed tapered walls, controls the flow of fluid from the inlet port to one of two load ports, and similarly con-trols the flow of fluid from the two load ports to respective exhaust ports.

Abstract: ABSTRACT OF THE DISCLOSURE A tyre chain having a tread part and side parts includes at least one tensioning device for the tensioning of the tyre chain in the operating state.  The tensioning device is linked to members of the tyre chain with two link members movable resiliently against one another to a stretched-out position, the link members in the stretched-out position being held in posi-tion relative to each other by a releasable locking means.  The tensioning device has at least two compression springs the two ends of which are generally level with each other and are operatively connected to the link members.  The tensioning device need have only a short length and can therefore be used in narrow mesh tyre chains or in tyre chains with small spacing, as for example, is the case with tyre chains having a bridge-piece-ring system.  With the use of at least two compression springs, the tensioning device according to the invention, in spite of a short constructional length thereof, can provide a comparatively high degree of tensioning so that the tyre chain when fitted can be satisfactorily tensioned and can be located securely on the tyre.  With the aforesaid releasable locking means, the tensioning device can be secured in its stretched-out position before fitting the tyre chain on the tyre so that the tyre chain, in spite of the high degree of tensioning can be easily fitted on to the tyre.

Abstract: ABSTRACT OF THE DISCLOSURE           A compact, rigid camera for use with self-developing film utilizes a prism element having an exit face overlying the film and which is both reflective and transmissive to fold the optical path of useful light rays between an objective lens and a film plane in a relatively small volume.  A prism entrance face is oriented with respect to the reflective/transmissive exit face so that entering light is totally internally reflected at the exit face to at least two other faces of the prism which are reflective and oriented to return the light to the exit face substantially along its perpendicular.  The exit face is coextensive with the film plane so that the reflected light transmitted through the exit face exposes the film.  In one form the exit face of the prism is planar and closely spaced from the film plane.  In another form the exit face has two mutually inclined planar surfaces, each of which internally reflects one image beam and transmits another beam internally reflected from the other face.  In the latter form an auxiliary emergent prism is interposed between the exit face reflective/transmissive surfaces and the film plane.

Abstract: ABSTRACT OF THE DISCLOSURE           A blown glass reflector lamp having an ellipsoidal reflector and a clear or lightly frosted face is disclosed. The lamp bulb is blown in the shape of half of an ellipsoid, the eccentricity of the ellipsoid being within the range of 0.88 to 0.66, inclusive,  The face of the bulb closing the ellipsoid can be clear or, preferably, lightly frosted.  An elongated neck is provided to separate the base from the filament to enable the base to remain cooler during lamp operation.  The length of the neck can be reduced if a heat-reflecting shield is inserted within the neck around the mount. The reflective layer terminates at approximately the minor diameter of the ellipsoid, so that the direct light and the reflected light diverge at approximately the same angle.  The face of the lamp is positioned close to the minor diameter, so that the light flux passing through is not sufficiently concentrated to cause high face luminance or overheat the glass.

Abstract: ABSTRACT OF THE DISCLOSURE            An improved process for the production of   2,4,5,6-tetraaminopyrimidine from   2,4,6-triaminopyrimidine which produces but does not isolate an intermediate   2,4,6-triamino-5-nitrosopyrimidine which compound is retained in situ and minimizes the complex polymer form of a three-dimensional network of azo linkages formed by the nitroso and amino groups.  These groups, as they appear in the nitroso intermediate, have carcinogenic possibilities,  It has been found that the nitroso compound will precipitate as a stirrable slurry if the temperature parameter is kept low at about 0-20°C.  A preferred route for the production of the nitroso compound from the triamino starting material utilizes as reactants 1.0-1.05 moles of sodium nitrite and 1.5 moles of HOAc in water (HCl may be substituted for HOAc).  In the second stage of this sequential reaction, the reduction of nitroso is carried out by a reducing agent and one preferred agent is sodium dithionite.          Catalytic agents such as Raney nickel and hydrazine or nickel salts, e.g., nickel chloride, and sodium borohydride may also be used.  The present process is an improvement in part of the technique of Piper and Montgomery, J. Het. Chem., 11:279 (1974), which process is designed specially to produce the antifolate methotrexate as an end product.

Abstract: ABSTRACT OF THE DISCLOSURE            A process is disclosed for the production of granular sulfur in a rotating drum in which molten sulfur at a temperature within the range of about 110° to 160°C, more pre-ferably about 119 to 159°C and most preferably about 130 to 158°C or about 10 to about 40 Celsius degrees above the sulfur melting temperature, is sprayed in a contact zone onto a bed of moving sulfur particles and a continuous curtain of said particles and resulting particles are passed to a cooling zone prior to discharge.  A countercurrent flow of substantially inert cooling gas at a temperature in the range of about 10 to 50°C and containing not more than 8% by volume oxygen is intro-duced to the cooling zone and a portion or all of said cooling gas is passed through the contact zone.  The contact and cooling zones can be formed in a single rotating drum and separated from each other by a retaining ring or formed in separate vessels.          The latter embodiment permits reduction in the total demand for cooling gas and enhances gas velocity and temperature controls in the contact zone by circulating a portion only of cooling gas through the contact zone.          Discharge particles from the cooling zone are separated according to size and undersized particles are recycled as fines to the contact zone at a ratio of 4:1 to 2:1 of fines to product granules.          Granular sulfur which is substantially pure, resistant to attrition, hard, and uniformly and closely sized is produced by a process wherein explosion hazard is substantially avoided.

Abstract: Abstract of the Disclosure The device comprises a closed container with a breathing tube and a means for variably adjusting the size of an aperture into the container.   A transparent inclined tube is mounted on the container and houses a moveable air flow indicating member.  The tube has a passage at the top leading into the container and a vent at the bottom of the tube allows air to enter to move the flow indicating member up the inclined tube. Air drawn from the container by inspiring through the breathing tube is replaced in part by air entering through the variable aperture means and by air entering through the vent.   By adjusting the size of the variable aperture, one can determine inspiratory capacity as correlated with the amount of air necessary to move the flow indicating member to the top of the tube or to an intermediate position in the tube.
