Title: Improvements in or relating to floating outlets for drawing off supernatant liquid
IPC: B01D17/02
Filed: 1931-01-14
Abstract: 370,072. Gravity-separation apparatus. WHITEHEAD & POOLE, Ltd. and NORRIS, F., Milltown Street, Radcliffe, near Manchester. Jan. 14, 1931, No. 1245. [Class 46.] Apparatus for drawing off supernatant liquid comprises a swinging conduit arm having an inlet which moves angularly about the axis of movement of the arm and is maintained by a float partly below and partly above the surface of the supernatant liquid, the depth to which the inlet extends below the surface being constant. The lower end of the conduit 1 is pivotally connected to an elbow pipe 5 and a valve 6 leading to an outflow conduit. The rectangular upper end is fastened to a threechambered hollow cylinder 7 so as to project radially through an opening 11 into a central chamber between two end chambers 10, which form float chambers. The large aperture 11 is so arranged that it remains below the surface of the liquid in all normal positions of the conduit 1, and another aperture 12 similarly remains above the surface of the liquid, so that scum is prevented from entering the cylinder 7. The side 14 of the conduit 1 terminates at the centre line of the cylinder, or in horizontal alignment with the centre line, and the opposite side 15 terminates at a level which is always above the centre line, the upper end of the conduit being inclined, as shown. The inlet aperture 16 may be adjustable in width and its lower extremity coincides with the upper edge of the side 14, so that its depth below the surface of the liquid is constant, and therefore the head of the liquid causing a flow is constant. This constant depth may be adjusted by inserting liquid or small slots into the float chambers through openings normally closed by screw plugs 17.

Title: Improvements relating to governors for fuel injection pumps
IPC: F02D1/00
Filed: 1944-01-25
Abstract: 575,013. Fluid-pressure servomotors. C.A.V., Ltd., and NICOLLS, W. E. W. Jan. 25, 1944, No. 1392. [Class 135] [Also in Group XXVIII] A pump e is driven by the engine and the delivery pressure is applied to pistons s and i that are connected by the lever m to the control rod p of the fuel-injection pump. When the engine is starting, the pressure immediately moves the piston s against the stop n to move the rod p to give maximum fuel supply. As the speed of the engine increases, the piston i controls the rod p, but if, for any reason, the pressure fails, the piston s will cause the fuel supply to be reduced to a predetermined maximum. The pressure acting on the piston i is resisted by the spring j and assisted by the spring h that becomes inoperative after the piston has moved a certain distance; the spring j is assisted by fluid-pressure that exists in passage c that is connected by the throttle l and the throttles z in the piston y to the delivery pressure of the pump e. The pressure in the space x<2> is limited by the relief valve 2 and the piston y adjusts a spring-loaded valve g controlling the pressure in the passage c. The spring loading of the valve g may be adjusted by the lever 7. In a modification shown in Fig. 2, the lever m is formed in two parts m<1>, m<2> connected by a spring v to, give a toggle action. When the piston s is actuated, the part m<2> abuts the stops w and n and the initial movement of the piston i causes the part m<1> to move the pin m<3> in the ring m<4> until the spring v snaps into its other extreme position when the rod p will be in the range that effects normal control of the fuel injection pump.

Title: Improvements in or relating to processes for the production of boron alkyls
IPC: C07F5/02
Filed: 1960-04-21
Abstract: Boron alkyls are made by reacting a boron halide with an alkyl zinc halide in solution in a N,N-dialkylamide of an aliphatic carboxylic acid, e.g. N,N-dimethyl formamide.  The boron halide is preferably boron trifluoride or boron trichloride, which is added in gaseous form or as a solution in N,N-dialkylamide, to a heated solution of the alkyl zinc halide in the N,N-dialkylamide.  The p  reaction is preferably effected in an atmosphere of nitrogen at a temperature between 50 DEG C. and 160 DEG C.  When the boron alkyl is of lower b.p. than the N,N-dialkylamide it may be distilled directly from the reaction mixture.  Alternatively, the reaction mixture may be diluted with water, and the boron alkyl extracted with a solvent of lower b.p., e.g. dimethyl ether, iso-propyl, ether, petroleum ether, chloroform and benzene.  The alkyl zinc halide solution in a N.N-dialkylamide is prepared as described in Specification 880,945. Examples describe the preparation of trimethyl-, triethyl-, tri-n-propyl and tri-n-butyl borines.

Title: Improvements relating to devices for delivering molten glass to glass-blowing machines
IPC: C03B7/00
Filed: 1929-01-15
Abstract: 314,480. Bullman Machine Co., Ltd., (Assignees of Hillmann, H.). June 28, 1928, [Convention date]. Delivering molten metal.-Relates to a furnace trough or forehearth for supplying molten glass to a glassblowing machine of the kind that gathers charges o. glass by suction. The moulds of the machine move in a circular path k, and each mould is preceded by a skimming-blade which clears away the chilled glass and causes a circulation of glass between the forehearth and the furnace. The forehearth c is separated from the body b of the furnace by a vertically movable gate h, and hot glass enters the forehearth beneath the lower edge of the gate. According to the invention, the gate does not extend across the whole width of the furnace opening but is supplemented by a fixed bridge d. The lower edge of this bridge is separated from the surface of the glass by a space f which is sufficiently deep to allow the chilled glass, pushed forwards by the skimmers, to pass freely into the furnace. The position of the gate h is adjusted so that the gap l, between its lower edge and the surface of the glass, allows the glass to flow freely into the forehearth but is not wide enough to allow excessive radiation from the furnace.
