Abstract: INVENTOR:  William S. Hollingshead INVENTION:  PROCESS OF PREPARING CATALYST             FREE AROMATIC DIAMINES                  Abstract of the Disclosure Primary amines and polyhydroxy aromatic compound are condensed in the presence of iron halide catalysts to produce diamine antioxidants.  Iron is known to accelerate oxidative degradation.  Its presence in an antioxidant com-position is therefore undesirable.  Dry calcium hydroxide is added to the diamine reaction mixture to precipitate the iron.  The precipitate is then filtered from the reaction mixture.

Abstract: INK JET NOZZLE STRUCTURE AND METHOD OF MAKING Abstract A nozzle array structure for pressurized fluid jets includes a uniform deposited membrane having an array of uniform small orifices therein overlaying a planar substrate having an array of larger aperture openings therethrough with approximately the same central axes as the orifice array.  The method of making includes forming a substrate of a planar single crystal material oriented with the (100) planes parallel to the surface.  A mem-brane comprising a uniform coating of an inorganic material is applied to the planar surface of the substrate.  The substrate is preferentially etched from the rear surface to form an array of openings therein extending therethrough to the membrane.  The membrane is then selectively eroded to form an array of uniform small orifices therein.

Abstract: ABSTRACT:         A substrate bearing a secondary-emissive layer which consists of a cermet consisting of a readily evaporable metal, for example Au, Ag, Cu, Ni, Cr, Al or a nickel-chromium alloy, and an alkali metal aluminium fluoride, for example cryolite. The substrate material may be, for example mild steel, or a synthetic plastics material. It is possible to make large dynodes when using mild steel substrates which are much cheaper than silver-magnesium or beryllium-coppor. The secondary-emissive layer does not require an activation treatment inside an electric discharge tube into which it is incorporated.

Abstract: Abstract of the Disclosure Whilst exhaust tubes cooled by compressed air have proved to be satisfactory when the content of dust in hot gases is to be measured, and electrically heated exhaust tubes have proved to be satisfactory when the content of dust in comparatively cold and wet gases is to be measured, it is in practice not convenient to use different types of exhaust tubes in the two instances.  The invention provides an apparatus for measuring the content of dust in gases which, without the necessity of exchanging the exhaust tube, may be used in both instances.  The apparatus includes an exhaust nozzle adapted to be arranged in a duct through which the gas passes, a filter housing connected to the nozzle by means of an exhaust tube construction, and a source for delivering a medium to passages provided in the exhaust tube construction.  Controllable heating means are provided for heating the medium between the source and the exhaust tube construction.  By means of the apparatus according to the invention it is possible to analyse the gas irrespective of the condition thereof, viz. by heating the medium when comparatively cold and wet gases are to be analysed and by using the medium, e.g. air, in unheated condition when cooling is required.

Abstract: ABSTRACT OF THE DISCLOSURE   A diaphragm valve construction for use with servo-regulated valves which substantially eliminates the problem of outlet pressure oscillation under low-flow high inlet pressure conditions. Briefly, the main diaphragm valve is constructed so that a larger effective area is provided on one side of the main valve seat than on the other, resulting in a hinging effect on the valve as it closes and opens. Under critical low-flow high inlet pressure conditions, one side of the main valve actually remains on the valve seat while the other side is lifted away from the seat to permit flow through the valve.

Abstract: TITLE           FLUID ACTUATED OPERATOR AND CLUTCH LINKAGE                ABSTRACT OF THE DISCLOSURE A fluid actuated operator and linkage for a clutch. The linkage includes an operator link connected between the operator and a throwout bearing actuator arm. The operator includes an operator rod pivotally connected to the operator link and extending through an axial bore of a sleeve internal of the operator housing. The sleeve is connected for movement with the clutch pedal. The sleeve and operator rod form a valve for connecting a source of fluid under pressure to a pressure responsive means in the operator to generate a force to move the rod and disengage the clutch as the clutch pedal is depressed. As the clutch pedal is raised, the valve vents the fluid pressure responsive means to reduce the applied force which allows the clutch pressure springs to return the clutch to engagement. Embodiments are disclosed which have nonlinear characteristics which correspond to the force/displacement operating curves of certain types of clutches.

Abstract: METHOD AND CONNECTOR DEVICE FOR  ELECTRICALLY AND HYDRAULICALLY CONNECTING A WATER-COOLED CONDUCTOR     ABSTRACT OF THE DISCLOSURE         A  method   of   electrically   and   hydraulically connecting a conductor bar having a plurality of hollow water-cooled conductors involves compressing the conductor bar and shims of brazing material in a connector clip formed of a pair of mating clip members.  Brazing shims (strips and bands) are placed  in desired positions,  and  then  the  components  are heated and hydraulically compressed.  The conductor bar and brazing material assembly is sized for a tight fit in one dimension,  but  oversized  in  another  dimension  so  that compression results in a desired distribution of the molten brazing material.   During compression, the clip members are secured from relative motion, other than displacement toward one another, and air is passed through the hollow conductors to prevent the accumulation of brazing material in the open ends thereof.  In addition to the clip members, the connector device  includes a water  inlet member with a stem that is inserted between and brazed to the clip members after the compression step.
