Filed: 1924-12-12
Abstract: 248,843. Dewrance, Sir J. Dec. 12, 1924. Lift valves; valves fitted with independently actuated supplementary valves. - A hand - actuated steam stop valve of large size is fitted on the inlet side A with a balancing piston E arranged to work freely in a cylinder open to a drain outlet C. In order to open the main valve G the drain outlet stop valve D is first opened; this discharges the water of condensation and relieves the pressure under the piston E thereby allowing the valve to come to balance as regards inlet pressure, whereupon the valve can be readily lifted by its screw or other handactuating means. A drain opening through the piston may be used if it is desired to fit the piston closely to its cylinder.

Filed: 1969-06-12
Abstract: 1,218,908. Drilling machine; grinding. CHICAGO BRIDGE & IRON CO. 12 June, 1969 [3 Oct., 1968], No. 29947/69. Headings B3C and B3D. A machine for drilling, reaming, tapping or grinding large diameter holes, for example, in a vessel 10 having a flange 11, has a frame comprising sections 17, 18 and 19 which can be adjusted for length by using spacers between the sections. The frame is pivotably mounted on a member 14 which is centrally positioned on the vessel by rods 12 and 13. Member 14 takes no load, which load is borne by the flange 11. Section 18 has two frame branches 23, 24. Wheels 31, 32, 42, 43, Fig. 3, rotatably mount the frame on the flange, wheel 31 is driven by a motor 47. Levelling legs 25, 26 and 38 are operated by air motors and act to lift the wheels off the workpiece and level the machine. Once this has been done hold-down clamps 29, 30 and 44, also operated by air motors, secure the machine in place. A power head 70 driven by a reversible electric motor 71, drives a spindle 73 through gearing 72. The lead 70 is mounted on a power head support 50 which can be moved sideways, forwards or backwards by air motors and can be clamped in a given position by a plate (61), Fig. 4 (not shown). The weight of the head 70 is counterbalanced by a counterweight 88; the head is moved by means of a screw 94 and a motor 95, the lower end of the screw is associated with an electrical mechanical brake to stop the motor from coasting when a stop control is operated. A drill shaft 75 is located in spindle 72 and has a spade drill 76. A bushing holder 100 supports the shaft 75 and comprises two different bushings, only one of which is used at any one time. Fig. 5 shows bushing 101 in an operational position with bushing 102 swung out of the way and held by a pin 117. The bushing 100 is adjustably mounted on the power head support 50. Movement of the bushing is either (1) by placing a bar 121, Fig. 5 and Fig. 11 (not shown), between the head 70 and the bushing such that the motor 95 moves the bushing; or (2) by the bushing being powered separately, Figs. 16-18 (not shown). A safety switch 111 restricts downward movement of head 70. The operating end of frame sections 18 has level support brackets 130 and 131 which hold levels 132 and 133. These enable correct setting of the machine relative to the workpieces. Removal of chips from a hole is by feeding coolant fluid through holes 140, 141 so that the chips are subjected to hydraulic lift. As shown the spade drill has guides 145, which may be spirally mounted to prevent drill wander. Filler pieces may be positioned between some of the guides to ensure a high upward velocity of the coolant. (For Figures see next page)

Patent GB-780557-A (GB)
Title: Improvements in or relating to colchicine compounds
IPC: A61K36/896
Filed: 1955-10-26
Abstract: The invention comprises colchicine derivatives of the formula: <FORM:0780557/IV (a)/1> wherein R is hydrogen or an acyl group, and tribenzoyl - O - demethyl - N - deacetyl - N-methylcolchiceine of formula: <FORM:0780557/IV (a)/2> together with processes for their preparation.  The parent O-demethyl-N-deacetyl-N-methylcolchicine is isolated from previously powdered and degreased seeds of Meadow Saffron by extraction of the active materials in known manner, preferably using water, an alcohol containing not more than six carbon atoms, or a mixture of such an alcohol with water or an aliphatic hydrocarbon containing not more than six carbon atoms, and then separating the above amphoteric compound by solution of the active materials in a water-immiscible organic solvent and converting all the basic constituents to their water-soluble salts, which are extracted with water, neutralized and extracted with a water-immiscible solvent, preferably a halogenated hydrocarbon, e.g. chloroform, tetrachloroethane or trichloroethylene, said organic solution being then basified to convert the acidic groups of the amphoteric constituents into water-soluble salts, which are then extracted with an aqueous medium, neutralized and re-extracted with an organic solvent, from which O-demethyl-N-deacetyl-N-methyl-colchicine is recovered.  The salinification steps may be effected in either order.  In examples: (1) pulverized meadow saffron seeds are de-fatted with petroleum ether, extracted with 70 per cent aqueous alcohol and after distillation of the alcohol in vacuo the remaining aqueous solution is extracted with chloroform, the extract shaken with N HCl and the aqueous portion after neutralization re-extracted with chloroforin, from which the amphoteric constituents are isolated by treatment with N/10 NaOH, neutralization of the alkaline extract and re-extraction with chloroform, which on evaporation and crystallization from methanol yields solvated O-demethyl - N - deacetyl - N - methylcolchicine; (2) treatment of this compound with acetic anhydride-pyridine yields the diacetate of O-demethyl - N - deacetyl - N - methyl - colchicine; whilst (3) hydrolysis with HCl followed by treatment with benzoyl chloride-pyridine gives tribenzoyl - O - demethyl - N - deacetyl - N - methylcolchicine; (4) O-demethyl-N-deacetyl-N-methylcolchicine is methylated with diazomethane to N-deacetyl-N-methylcolchicine and then (5) acetylated with acetic anhydridepyridine to N-methylcolchicine.

In a system for evaluating the area between a selected pair of adjacent curves 1, 2, 3, 4, Fig. 1, the curves are repeatedly scanned 13 and during each scan line each time a curve is detected a bi-stable trigger device is set on, that is for each scan line when the first curve is detected a first trigger 18, Fig. 3, is set on, when the second curve is detected a second trigger 19 is set on &c., all the triggers being reset off at the end of each scan line, the outputs from adjacent triggers are then gated together 21, 22, to develop signals representing, by their durations, the spacings between adjacent curves, and a selected one of these signals is integrated by counting clockpulses synchronized in frequency with the scanning. As described, the graph is wrapped around a continuously rotating drum 6, Fig. 2, and is scanned 11, 14 photo-electrically, the beginning of each scan line being marked by an adjustable marker 23 also detected 24 photoolectrically. Clock pulses are generated by a photo-electrically sensed apertured disc 8. A logical circuit is described (Fig. 6, not shown) which evaluates the area under a gas chromagram and which compensates for imperfections in the graph and for dirt on the paper.

Abstract: 1393747 Hydro-static transmission control EATON CORP 30 June 1972 [30 June 1971] 30801/72 Heading F2D In a control system for two separate hydrostatic transmissions 12, 13 driving tracks on opposite sides of a vehicle wherein each transmission has a variable displacement pump 14, 14a adjusted by a follow-up servo-motor 36, 36a, the pilot valves 28, 28a of the servo-motors 36, 36a are positioned by fluid motors 22, 22a supplied with pressure liquid through a main control valve 20 which identically adjusts both fluid motors 22, 22a and through steering valves 200, 202 which selectively adjust the motors 22, 22a for steering purposes. Movement of a mannual speed control lever 16 acts through springs 52, 54 to move a spool 44 of the valve 20 down (or up) and thereby connect a supply line 69 to a line 70 (or 72). The pressures in the lines 70, 72 act on opposite sides of pistons 74, 74a of the fluid motors 22, 22a and move the pistons right or left against the bias of centring springs 24, 24a. Linkages 30, 30a transmit the movement of the pistons 74, 74a to the pilot valves 28, 28a. Pistons 114, 114a of the servomotors follow the movement of the pilot valves 28, 28a and act through linkages 122, 122a to adjust the angle of swash plates 18, 18a of the pumps 14, 14a. The pressure rise in the line 70 (or 72) acts additionally on the end of the valve spool 44 and moves the latter back to the central position shown in which it blocks the lines 70, 72. The movement of the pistons 74, 74a and the displacement of the pumps 14, 14a is thus proportional to the movement of the lever 16. To steer the vehicle a pedal 204 (or 206) is depressed to actuate the associated steering valve 200 (or 202). Each steering valve has a valve spool 222 which, on initial depression of the associated pedal 204, is moved right to block fluid supply lines 210, 212 and to interconnect lines 224, 226 to the associated fluid motor 22 through a throttling land 230. The pressures on opposites sides of the piston 74 are thus slowly equalized and the spring 24 moves the piston 74 to its central neutral position. The output speed of the associated transmission 12 is thus reduced to slow the track on one side of the vehicle and effect steering. If rapid turning is required further depression of the pedal 204 connects the line 210 with the line 226 and also connects the line 212 with the line 224. The pressures on the piston 74 are thus reversed and the associated transmission 12 is put into reverse to effect rapid turning of the vehicle.
