Abstract: Abstract A heat transfer surface for boiling liquid re-frigerant 11 and its equivalents and method for producing the surface.  The surface comprises a porous, open-cell coating at least 15 mils thick, of oxidized metallic par-ticles which are flame-sprayed onto a metal substrate. This surface includes a substantial number of nucleate boiling cavities having an equivalent radius in the range of 1.5 to 4 mils, which are the result of one or more of the following conditions in the flame-spraying process: 1) The flame-spraying nozzle is oriented so that the metallic particles impact the metal substrate at an angle in the range of 30° to 75°; 2) The metal substrate is pre-heated to a temperature which is at least 600°F, but below the melting point of the substrate; and 3) The flame-spraying apparatus is positioned such that the metallic particles travel from 3 to 6 inches before impacting the substrate.  These conditions create a porous coating with substantially more nucleate boiling cavities of the re-quired size for boiling liquid R-11 than the flame-spraying process disclosed in the prior art.

Abstract: PNEUMATIC CONTROL FOR BRAKING SYSTEM   PROVIDING SNOW BRAKE OPERATION              ABSTRACT OF THE DISCLOSURE     A railway vehicle braking system is provided with a "snow brake" control arrangement which is used in freezing temperatures to apply a small brake force for prolonged periods to engage blocks or shoes on the vehicle wheels to reduce icing.  The "snow brake" control arrangement itself includes an pneumatic valve system that includes a relay valve unit which, in a first mode, provides "snow brake" operation and, in a second mode, provides for application of brake pressure from the straight air pipe to the brake cylinders.          A solenoid valve, actuated responsive to energization of a control solenoid by a snow brake control switch, controls connection of "snow brake" pressure from a supply reservoir to a control chamber of the relay valve.  When the straight air pipe is pressurized responsive to call for service or emergency braking, the solenoid is de-energized and the con-trol chamber vents to atmosphere through the solenoid valve.          The relay valve provides a delay in re-energization of the solenoid, and hence in effecting reinstatement of "snow brake" operation, so that the slack adjusters can make whatever slack adjustment in the brakes that is necessary.

Abstract: IMPROVED DUAL-MODE ELECTRON GUN         By Richard B. True ABSTRACT       An improved dual-mode electron gun includes a close-in and a further control grid to control the laminar flow of electrons which pass from the smooth spherical surface of a cathode toward an annular anode.  In the high mode of operation, the close-in grid is maintained, for example, at +36 volts while the further grid is maintained at +250 volts. During the low mode of operation,  the close-in grid is maintained at -36 volts while the further grid potential is +250 volts.   The two control grids are divided  into inner circular and an outer annular areas. The close-in grid has more conductive elements in its outer annular area than in the same area of the further grid. The two grids are then aligned so that the close-in grid functions as a control grid to block the flow of electrons from the outer annular area during the  low mode  of operation and as a shadow grid for the further control grid during both low and high modes of operation.

Abstract: A METHOD OF DETERMINING THE LENGTH CHANGE OF A       STRING OF WELL PRODUCTION TUBING            Abstract In a method of determining the length change of a string of tubing in a vertical or deviated well caused by fluid flow through the tubing during production or stimulation of the well, the pressure of the fluid is measured where the fluid enters the tubing and, for successive sections of the tubing, the actual force applied to the tubing is determined from the fluid pressure acting upon the cross-sectional area of the tubing.  The inclination and weight of each section of the tubing is measured and from the measured inclination the weight of each section is resolved into the axial component applied to the next successive segment.  For each of the successive sections, the buckling force is determined from the actual force and the axial component of the weight and then the buckling force is compared to a threshold to determine if there is buckling of the tubing.  The length change of the tubing between the initial condition and the condition of fluid flow in the tubing caused by the pressure and temperature of the fluid and caused by any buckling is then determined and an output is produced indicating the change in length of the tubing.

Abstract: Polymerisation of Conjugated Dienes Abstract The invention relates to a catalyst system comprising (a) a compound of a rare earth element and, as cocatalyst, a second component (b) comprising an organomagnesium compound.  In the polymerisation of a conjugated diene this catalyst gives a polymer having a very content of trans 1,4 isomer.  A third component (c) which is a Lewis acid alters the reaction to give a polymer having a very high content of cis 1,4 isomer.  If desired reaction can be initiated using components (a) and (b) alone and component (c) then added at the desired conversion to produce a block polymer having a block of high trans content followed by a block of high cis content.

All stages of the process can be carried out in a single re-action medium, without separating intermediate products.
