Title: Improvements in or relating to fluid pressure regulators
IPC: G05D16/18
Filed: 1928-02-28
Abstract: 288,166. Canada Sugar Refining Co., Ltd., (Assignees of Wettstein, F. A.). March 31, 1927, [Convention date]. Fluid relays, - Relates to fluid pressure regulators of the servomotor type controlled by variations in any physical condition or quantity, such as the speed of fluid pressure motors, temperature, water level, electrical or chemical conditions, such as the CO2 content of combustion gases, wherein means are provided whereby the static pressure of the fluid operating or controlling the servomotor is utilized directly to oppose the force immediately determining said static pressure and to balance the said force. By this means dash-pots in the regulating mechanism are avoided, and the regulating mechanism is connected to the mechanism operating the control member by one or more fluid pressure conduits only without the aid of mechanical interconnection, so that the two mechanisms may be disposed at a distance the one from the other. Fig. 1 shows a pressure regulator controlled by a speed governor and embodying a direct resilient fluid pressure return motion ; the speed governor, however, merely typifies means responsive to any regulating impulse. With a decrease of speed, the governor spring 8 moves upwards, the combined piston pilot valve 10, 11 and return motion piston 17 allowing regulating pressure fluid entering at 15, 16 to pass through conduit 19 to the servomotor piston 24, and also through the pipe 23 to the upper side of the return motion piston 17; simultaneously, fluid from the opposite sides of the pistons 17 and 24 escapes through conduits 20 and 22 to the discharge 12. The consequent pressure differential in the servomotor 21 moves the piston 24 upwards to open the valve more to give an increased power supply to the prime-mover, and also forces down the returnmotion piston 17 until the pilot valve 10, 11 reaches its normal position; in this position the process of regulation is completed and the pistons 17 and 24 are stationary. In the absence of a loading spring 25, the speed at the close of the regulation is the same as at the beginning and variations are only temporary. Permanent variations of speed according to load can be provided for by a loading spring 25 of suitable stiffness. An arrangement is shown in which increased power and accuracy of control are obtained by providing two relays in series, one relay valve being disposed on the servomotor cylinder, and the return motion piston 17 being separated from the governor rod 9 and operating thereon through a spring.

Void [Abridged as open to inspection under Sect. 91 of the Acts, Nov. 9, 1934]. [Class 80 (ii)] Variable-speed ratchet gearing suitable for vehicles comprises a pair of governor-controlled variable-throw driving cranks 11, Fig. 1, instead of a single such crank, as in the arrangement of Specification 313,494, [Class 80 (ii)]. The crank-pins 11 are carried by blocks 6 which slide transversely in two frames 5 which are rigid with two gears 4 which are fixed in position and are driven from a single gear 2 fast on an engine shaft 1 without the usual main clutch. The throw of the two cranks is varied simultaneously by two pairs of non-rotary friction discs 8, 9. The two discs 8 or the two discs 9 are brought into engagement with two friction pinions 10 fast on diametral screws 7 which are threaded into the blocks 6 and moves these blocks radially out or in. The pins 11 are connected by rods 12, Fig. 2, to two pins 16 side by side on a disc 3 so that as the pins 11 revolve in small circles of variable throw, the disc 3 oscillates with correspondingly varied amplitude. The drive is passed on from the disc 3 through one-way grip rollers 17 to an outer flanged disc 18, Fig. 1, and then through a coil spring 27 to a block 58 past on a shaft 15 which is thus driven resiliently in one direction. The block 58 houses governor weights 28, which, as they fly out centrifugally, through toggle links 29 thrust axially a sliding sleeve 30. The sleeve 30, Fig. 4, is connected to axial links 31 each of which is jointed to a balancing lever 46, Fig. 5, which distributes the thrust of the sleeve 30 equally between the two pairs of control discs 8, 9 to thrust them axially against the rollers 10. In starting the vehicle, depression of the accelerator 33, Fig. 4, through a linkage 59, 35, 60 thrusts the sleeve 30 axially so as to move the cranks 11 out from their central to a driving position. After starting, the governor weights adjust the speed ratio.

Title: Improvements in or relating to improvement in process for the preparation of pentachlorophenol and octachlorocyclohexenone
Filed: 1952-03-20
Abstract: Pentachlorophenol and octachlorocyclohexenone are prepared by reacting phenol with chlorine at an elevated temperature, e.g. 120-140 DEG  C., until the chlorine content corresponds to trichlorophenol, adding a metal halide chlorination catalyst such as ferric chloride, continuing the chlorination until the products have a chlorine content corresponding to tetrachlorophenol, adding preformed octachlorocyclohexenone in an amount constituting 10 to 50 mol. per cent of the reaction mass and continuing the chlorination at 120 DEG  to 140 DEG  C. until the desired chlorinated compound is formed.  Alternatively, where the desired product is octachlorocyclohexenone, the process may comprise chlorinating pentachlorophenol in admixture with 10 to 50 mol. per cent of preformed octachlorocyclohexenone in the presence of ferric chloride at a temperature from 120 DEG  to 140 DEG  C. until two mols. of chlorine per mol. of pentachlorophenol have been consumed.  When the desired product is pentachlorophenol it is necessary to separate it from the octachlorocyclohexenone and other constituents of the reaction mixture, e.g. by solvent extraction or crystallization.  In examples: (1) and (2) phenol is chlorinated at 130 DEG  C. until trichlorophenol is formed, anhydrous ferric chloride is added and chlorination continued until a tetrachlorophenol is formed and octachlorocyclohexenone is then added and chlorination continued until the whole of the reaction mixture is converted to octachlorocyclohexenone; and (3) pentachlorophenol is chlorinated at 120-130 DEG  C. in the presence of octachlorocyclohexenone until the whole of the reaction mixture is converted to octachlorocyclohexenone.
