Title: Improvement in illumination of rooms
IPC: F21V17/02
Filed: 1945-04-10
Abstract: 589,797. Mounting reflectors. SCHWARZMAYR, L. April 10, 1945, No. 8906. [Class 75 (ii)] [Also in Group XXIII] An illumination unit comprises a globe 5, Fig. 2, above a light source 4 and a reflector 10 with supporting means 13 engaging the globe firmly adjacent to its major circle 13a but movable upwardly away from the major circle to a loosely slidable position 13b, this supporting means being also movable from the loosely slidable position towards the major circle of the globe. To loosen the reflector, the rim 18 of the reflector may be engaged from underneath by a hollow 16 in a reflector adjusting tool, Fig. 4. After adjustment to the new position, the supporting means may be brought into tight contact with the globe slightly above its major circle by the hook 17 engaging the upturned rim from above. The globe 5 is rigidly supported from the ceiling by a conduit 2 and is rotatable between collars 8 and 9 on a vertical axis, the reflector being thus adjustable to any position about the light source by a horizontal force applied to the reflector to rotate the globe. Specification 589,757 is referred to.

Title: Process for the manufacture of new conversion products from natural resins and esters thereof
IPC: C09F1/00
Filed: 1932-03-30
Abstract: Natural resins or the corresponding resin acids or the esters thereof are treated with volatile inorganic halides to give new products. Suitable natural resins for treatment include colophony, pine resin, Batavian damar, gum mastic, copal, esters thereof with dodecyl alcohol, glycol or glycerine or mixed esters known as alkyd resins. Inorganic volatile halides suitable include titanium chloride, aluminium chloride, tin tetrachloride, and boron fluoride or compounds thereof such as acetatofluoroboric acid or formatofluoroboric acid.  Solvents that are inert to the reaction conditions such as carbon tetrachloride carbon disulphide and hydrocarbons such as benzene, toluene, xylene, ligroin or tetrahydronaphthalene may be used.

[Also in Division B8] Apparatus for transferring an article from one station to another for fabrication, powerwashing &c. along a path omprises a transfer member 104, a rotary drive 110, 116, means 156, 162, 158, 166 for converting the rotary motion to a controlled vertical component of motion for the transfer member, a crank arm 172 connected to the rotary drive and means connecting the arm to the transfer member including a slotted guide 170 constituting vertical-lost-motion coupling means and horizontal-motion-cam means for controlling the horizontal component of motion of the transfer member by absorbing a predetermined amount of the horizontal component of motion produced by the crank arm, the crank arm having antifriction means 176, 178 engaging the guide. A speed-drop-cut-out switch 128 shuts down the drive if motor over-load occurs. Rotation of the cam 156 lifts the lever 158 which carries the rollers 162 bearing on the transfer bar 104 to ralse it. Inter-connected levers and rollers support the bar at other spaced points. Horizontal motion is imparted to the bar by the cams 170 and the rollers 176, 178 on the crank 172. The cams are shaped to prevent horizontal motion of the bar whilst the bar is being moved vertically by the cam 156. In a modification, the crank 172 carries only one roller 276, Fig. 6 (not shown), which is guided against the appropriate cam 270 by a pivoted guide 275 biased by a weight 277. Crankshafts to be machined are delivered first to roller supports 108a. At other stations they are supported by V-blocks 108. The shafts may remain at a station for a timed interval. The transfer bar 104 carries V-blocks 106a, 106 and a crank-shaft angular-setting device 107.

Abstract: 1,132,011. Welding by pressure. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 17 Feb., 1966 [4 March, 1965], No. 9293/65. Heading B3R. A method of repetitively welding together metal strips comprises securing the strips in abutting relationship on the worktable of a metal working machine, securing a pair of spot welding electrodes in the tool receiving part of the machine, moving the worktable to bring the strips into alignment under the electrodes and moving the electrodes to engage over the abutting strips and passing current to effect the desired spot welds. In the spot welding of stainless steel strips to form a grid for nuclear fuel rods the strips are assembled on the worktable of a drilling machine and the electrodes fitted in place of the drilling spindle. As the electrodes are lowered they are parted by the strips, one or more limit switches being used to control the depth at which spot welding occurs. The drilling machine may be adapted for control by punched tape control means.

Abstract: 555,558 Centrifugal separators; cracking hydrocarbons; catalytic apparatus. STANDARD OIL DEVELOPMENT CO. July 8, 1942, No. 9507. Convention date, July 12, 1941. [Class 23] [Also in Group III] Cyclone separators 21, Fig. 3, are arranged about a common inlet pipe 20 and several such sets are arranged in vertical sequence. Oblique partitions 32 guide the separated solids to a common dust conduit 35. The conduit is kept filled with solids by means of valves 17, 18 to prevent a back flow of gas through it. In a modification, the separated solids fall from each cyclone set on to a conical cover on the next set beneath and are guided to annular conduits between the outer shell and cylindrical extensions of the conical covers. The lower parts of these extensions are buried in the mass of separated solids to prevent back flow. In a third form, Fig. 5, for the production of gasoline from higher-boiling oils by cracking in the presence of a finely divided catalyst, the hydrocarbon entering at 60 penetrates a mass of powdered catalyst 45. The dust laden vapour enters annular groups of cyclones from above and in vertical sequence and the cleaned vapour passes out at 30. The central dust tubes carry sufficient solids to prevent back flow. The catalyst is withdrawn at 80, passed to a regeneration unit and returned at 82.
