Title: Improvements in or relating to fluid mixing valves
Inventor: FOX LESLIE
IPC: G05D23/13
Filed: 1956-10-18
Abstract: 810,627. Thermally-actuated valves. SIGMUND PUMPS Ltd. June 12, 1957 [Oct. 18, 1956], No. 31777/56. Class 135. A valve for mixing fluids of different temperatures comprises a casing 15 having coaxially-alinged inlets 17, 18 and an outlet 19 and a double-headed valve member 23 disposed between the inlets and secured to an arm 32 rotatably mounted on a spindle 12 to which is secured one end of a thermo-sensitive bimetallic-spirally wound coil 24. The arm 32 projects beyond the valve member and carries a peg 37 which engages the other end of the coil. Unwinding of the coil moves the valve member towards one inlet and winding of the coil, towards the other inlet to maintain a substantially constant temperature of the mixed fluid. The spindle 12 which passes sealingly through the casing has attached thereto a control lever which together with a set-screw carried on an extension of the lever, can initially set the position of the valve member to adjust the operating temperature. A baffle 42 across the casing deflects the stream of mixed fluid on to the coil 24 before passing to the outlet to ensure a quicker and more accurate operation of the valve.

Title: Improvements in the method of and means for controlling electrically driven hauling and hoisting engines
IPC: B66D1/12
Filed: 1923-12-19
Abstract: 224,397. Bousfield, G. W., and Ashton & Co., Ltd., D. Dec. 19; 1923. Regulating and control-transmitting gear for winding and paying-out apparatus.-The clutches of electrically-driven winches are interlocked with the motor control so that the clutch cannct be engaged until after the motor is started, and :nust be taken out before the motor is stopped, the arrangement also being such that the interlock is broken during the main run leaving the clutch under full manual control. Fig. 2 shows a construction in which the clutch consists of a band brake h used to fix or release one member of epicyclic driving gear. Turning the screwed shaft g by the hand-wheel j in the direction for engaging the clutch first results in the serrated friction face of the collar l rotating a loose chain wheel e geared to the motor controller spindle, thus starting the motor. As the turning proceeds, the advancing lug n<1> slackens the spring n by the time the clutch is engaged, thus leaving the wheel e free from the collar l. The clutch can then be operated manually and independently of the controller. On the full reverse movement of the shaft after the clutch is taken out, the spring n is re-compressed until the wheel e is rotated again to stop the motor.

Title: Improvements in multi-story presses
IPC: B27D3/02
Filed: 1969-06-24
Abstract: 1,255,422. Presses. MOTALA VERKSTAD A.B. 24 June, 1969 [27 June, 1968], No. 31881/69. Heading B5F. The multi-platen press of Fig. 1 comprises a stationary platen 1 and movable platens 2-5 interconnected by a number, e.g. four, lever arm systems each comprising pivoted arms 6, 7 and rods 8 pivoted to the platens 5 and attached at their other ends to members 9 pivoted to the arms 6, said members preventing, during the pressing operation, overloading of the lever arm systems, and eliminating the effect of the weight of the platens. Each member 9, Fig. 2, comprises a cylinder 16 closed at its lower end by a part 17 with trunnions 18 by which the member is pivoted to an arm 6. A piston-rod 14 depends from the cylinder and is attached to the upper end of a rod 8, and a friction assembly comprising friction rings 10 with intermediate thrust washers 11 and end thrust washers 12, 13 is positioned between the piston-rod and cylinder. A piston 22 is urged against the assembly by pressure fluid from a source 33 and influences the force to be applied by the rod 8 to cause movement of the pistonrod and friction assembly relative the cylinder. Some pressure fluid bleeds through passages 27, 28 and fills cavities in the assembly and passes via a passage 29 to a tank 31. During initial press closure there is no movement of the pistonrod in the cylinder, but when the pressing operation begins, and during any drying of the material being pressed, relative movement may occur in response to differences in the thickness, quantity &c. of the material located between the various pairs of platens. If such relative movement during a drying period is undesired the upper end of each cylinder may be extended, Fig. 3, not shown, to receive a piston which bears down on to the upper end of the piston-rod and is subjected to pressure fluid; during the pressing operation such pressure fluid is not applied. Instead of a fluid actuated piston 22, a spring may act on the friction assembly. In a modification the piston-rod 14 may be connected to the lever arm 6 and the cylinder 16 to the rod 8, and the friction rings urged inwardly against the piston-rod.

Title: Improved heating apparatus using a burner for fuel oil
IPC: F23D5/00
Filed: 1947-12-04
Abstract: 651,857. Liquid-fuel burners. LEVEY, L. W. Dec. 4, 1947, No. 32039. '[Class 75(i)] [Also in Group XXIX] In a heating apparatus for burning vapour given off from fuel oil contained in a well having two straight sided w a 11 s arranged one within the other and joined at their lower edges, the inner wall being inclined outwardly and 'downwardly and the outer wall inclined inwardly and downwardly so that the surface area of the fuel progressively and evenly decreases as its level is lowered from the top to the bottom of the well, means are provided for varying the level and consequently the surface area of the fuel in the well to control the rate of vaporization and heat emission from the burner. The apparatus comprises a burner having inner and outer perforated tubes 17 and 19 seated on an annular oil well 11 of Vee shape in radial section, the level of oil in which is controlled by a float valve mechanism regulated by a thermostat having inner and outer metal tubes 67 and 66 of differing expansion coefficient. As the burner temperature increases the inner tube 67 of the thermostat moves upward to allow lever 46, constrained by spring 56, to move outward to bring the conical end of valve 63, close to seating 44 in the valve body 42, Fig. 4. When lever 46 is in this position it maintains a level L 2 -L 2  since any slight increase in oil level within the cistern 31 raises float 58 to press the conical end of valve 63 on to seating 44 thereby cutting off the fuel supply. When the fuel is at this level (L 2 -L 2 , Fig. 2), within the Vee shaped oil well 11 it will be seen that any rise or fall will cause the surface area of the oil and hence the rate of vaporization and heat emission to the burner to rise or fall. If the burner temperature decreases the inner tube 67 moves downward to force lever 46 inwards and valve 63 away from seating 44. When in this position the fuel reaches a higher level (L 1 -L 1 , Fig. 2) before raising the float sufficiently to close the fuel supply valve 63. At this level, the surface area of the fuel in well 11, the heat emission and also burner temperatures are increased. The limits of the pivotal movement of lever 46 are determined in the outward direction by contact with the upper portion of the valve body 42, and in the inward direction by contact with lock nuts 54 and 55. In an alternative method of construction the oil level variation within well 11 may be obtained by keeping the fuel level in cistern 31 constant and raising and lowering the burner. The burner may be rectangular or elliptical instead of being circular.
