Title: Procedure and apparatus for continuously coating strip metal
IPC: C23C2/40
Filed: 1945-02-07
Abstract: 588,281. Coating metals. WORTHINGTON, W. Feb. 7, 1945, No. 3135. [Class 82 (ii)] In a method of coating metal with a protective metal, the metal to be coated is heated to the melting point of the coating metal, immersed while hot in a molten bath of the coating metal and, after removal from the bath, is subjected to a blast of fluid under pressure to strip excess coating metal therefrom and spread the coating. As shown, a strip of metal 10 after being fed through a heating unit 6, a flux bath 7 and a bath 14 of molten metal, is subjected to a blast of fluid from two nozzles 40 directed downwardly and inwardly towards the strip, and finally is fed through a cooling unit 9. The heating and cooling units 6 and 9 may each be formed of two separate units of tubular elements 26, one on either side of the strip, arranged so that the heating or cooling medium passes in a sinuous course through each element in turn. Hot or cold gas may be circulated through the respective units in order to maintain an even temperature in each zone. The fluid projected from the nozzles 40 may be a gas or may be a liquid, as for example the protective liquid 16 on the surface of the bath. The thickness of the coating may be adjusted by changing the angle of incidence of the fluid from the nozzles, varying the fluid pressure delivered to the nozzles, varying the speed of the strip or varying the temperature of the fluid delivered to the nozzles, or a combination of these.

Filed: 1961-01-30
Abstract: 915,442. Valves. GROVE, M. H. Jan. 30, 1961 [July 18, 1960], No. 3508/61. Class 135. A valve construction, such as a butterfly valve, comprises a valve body member 10 having flow passages 11, 12, a valve member 16, a resilient seal ring 39 located in an annular recess 47 in one of the members, and comprising a base portion 43a, 43b compressed within the bottom of the recess and flexible side wall portions 41a, 41b joined by a curved end wall portion 41c, the base and wall portions enclosing a space 51, the curved wall portion being engaged by a working surface of the other member of the valve. As shown in Figs. 2 and 3, the seal ring, which may be of a synthetic material, such as nylon or neoprene, is formed with enlarged portions 43a, 43b so that, when the ring is compressed into the recess 47, it is firmly retained therein and completely seals the space 51; the mating faces 47a, 47b may be corrugated or one provided with a tongue for engagement in a groove in the other in order to prevent relative movement. In operation, working fluid flows into either of spaces 49a, 49b depending upon the direction of flow, and forces the ring into firm contact with the opposite side of the recess and the closure member, as shown in Fig. 4. In order to prevent undue distortion of the ring, the space 51 may be filled with a liquid, such as water or glycerine, or a core of natural or synthetic rubber. In the embodiment shown in Fig. 11, applied to a gate valve, the ring is located in a groove formed by the housing and a threaded ring 142, the edges of the groove being provided with lips 144, 147 in order to prevent extrusion of the seal ring. In a modification, the lips may be replaced by a pair of Belleville washers 154, 155, Fig. 13, which serve to support the seal ring and also to scrape the closure member to remove dirt. The sealing ring arrangement may be also applied to a rotary spherical or rotary cylindrical valve.

Title: Improvements in and relating to fluid flow control valves
IPC: G05D23/185
Filed: 1963-01-29
Abstract: 985,252. Fluid-pressure servomotor signal systems. POWER REGULATOR CO. Jan. 29,1963 [Feb.12, 1962],No. 3579/63. Heading G3P. A valve for alternatively controlling the flow of heating or cooling fluid into heat transfer relationship with a fluid medium in accordance with the temperature of the medium comprises a valve member 100, Fig. 4, controlling the heating or cooling fluid passing from an inlet 93 to an outlet 95. The valve is actuated by a diaphragm 82 subjected to a signal pressure fed to chamber 113 or 114 depending on whether the valve controls heating or cooling fluid respectively. A valve stem 102,fixed to the diaphragm carries retaining rings 132, 137 for spring abutment members 130, 135. Assuming heating fluid is being controlled, a signal pressure is fed to chamber 113 and the diaphragm moves until the spring abutment 135 engages the housing and the valve 100 is fully open. If the temperature of the medium rises above a predetermined value,the signal pressure increases until the pressure is sufficient to move the diaphragm against the loading of spring 136 and the valve 100 moves to a partially closed position corresponding to the signal pressure. The valve acts in the same manner when controlling cooling fluid except that the valve 100 is closed when the abutment 130 engages the housing and an increase in signal pressure when the temperature of the medium rises above the predetermined value causes the diaphragm to move upward to partially open the valve 100. The signal pressure is provided by a control valve 31, Fig. 3,which comprises a bimetal valve element 40 controlling the leakage from a nozzle 42 to provide a signal pressure in conduit 35 connected to chamber 113 or 114 and an instant pressure supply. The nozzle 42 is carried by interconnected small and large bellows 60, 61 whereby then the valve moves towards the nozzle with increased temperature,the subsequent increase in fluid pressure in the bellows moves the nozzle 42 away from the valve 41 while still providing a signal fluid pressure proportional to the temperature. A valve may be provided in the connection between conduit 35 and chamber 113, 114 which connects the conduit to the different chambers in response to different acting pressures of the valve.
