Title: Improvements in constant-flow hot and cold water blending devices
Inventor: BRANSON CHARLES D
IPC: F16K11/24
Filed: 1951-07-06
Abstract: 712,049. Mixing liquids in proportion. ROBERTSHAW-FULTON CONTROLS CO. July 6, 1951 [July 7, 1950], No. 16114/51. Class 86 [Also in Group XXIX] The flow of hot or mixed hot and cold water respectively from chambers 11, 12, Figs. 1 and 2, via passages 18, 20 to an outlet conduit 16 is controlled by valves 32, 33. The opening of either passage 34, 35 through these valves by valves 30, 31 actuated by solenoids controlled in timed sequence in a washing machine relieves the closing pressure behind the valves 32. 33 produced by leakage from chambers 11, 12 so that one of the valves 32, 33 opens. When the valve 32 opens hot water opens a spring-loaded check valve disc 58, flows round the edge of the disc which acts as a flow responsive device and passes through ports 54 to the chamber 11, a cylinder 56 attached to the disc regulating the opening of the ports to keep the hot water inflow constant. When the valve 33 is opened, cold water flows past check valve 59 and constant flow valve 55 ,57 to mix with hot water passing a spring-loaded check valve 67 and constant flow valve 65, 66 in a chamber 15 connecting the chambers 11, 12. The springs 61, 68, respectively, of the constant flow valves 57, 66 allow each of these valves tb pass half the flow of water that is allowed by the spring 60 of valve 56 so that the outflow of either hot or mixed water is the same.

IPC: A01K31/19
Filed: 1916-11-14
Abstract: 103,283. Justice, P. M., (Cyphers Incubator Co.). Nov. 14, 1916. Rearing-appliances.-A chicken hover is formed with an upper sheet-metal body having a flat circular top 10 and upright cylindrical walls 11, and supported on legs 13 secured by removable bolts, the part below the upper body being closed in by slit curtains 14 of two thicknesses of textile material. The sheet-metal body, which is insulated by asbestos &c. 12, has suspended within it a radiator 15, which communicates by a flue 18 with a receiving-chamber 32 for the products of combustion of the lamp. The hot air reaches the atmosphere by passing round a baffle 19 in the radiator to a chimney 20 provided with a cap 21 and a gauze layer 22. The lamp is enclosed in a cylindrical lamp casing cut away at one side to provide an opening 29 for the introduction of the lamp. This opening may be partly or wholly closed by moving a curved shutter round the casing. Gauze-covered openings 42 are provided in the shutter, and the supply of air to the lamp controlled by their position relative to the edge of the casing. The top of the casing is provided with an eccentric thimble 30, which is adapted to fit into the chamber 32 in the body of the hover, and is secured to the body of the hover by bolts and thumb-nuts 37. The lamp, which has its burner eccentrically situated with regard to its cylindrical body 23 and has its filling-aperture so situated that the lamp cannot be filled while in the container, is provided with a metal chimney 25 having a mica-covered opening 60, a mirror 45 and sight-opening 46 being provided in the lamp-container to enable the condition of the flame to be seen. To remove the chimney from the burner to permit the withdrawal of the lamp, the chimney is provided with an arm 43 which may be raised and swung into engagement with a hook 44. The lampcontainer is shielded from the main part of the hover by a curved plate 47. The air passing between the plate and the container enters a receptacle 33 forming a jacket round the heated chamber 32, and thence flows through openings 50 into the hover. The hover is provided with a thermometer, and also with a thermostat controlling the operation of an air-damper 54. To facilitate the movement of the air, the radiator is provided with a central passage 56.

If the powder is applied by a current of air or gas, the electric charge may be applied by supplying the potential to a nozzle E, which is insulated or of nonconducting material, by an insulated cable F which may pass through a water jarket B<3> of a pouring trough B used in a centrifugal mould, or if the supply tube D<7>, Fig. 15. is also of insulating material, it may serve as a handle and being connected to a flexible pipe D<6> charged powder can be applied to the bell end of a centrifugal pipe mould A. In another modification. one section of the powder supply pipe is of metal and charged with static electricity and the adjacent sections are of insulating material. If the powder is fed by a screw G<2>, Fig. 9. the end g<2> is also of nonconducting material. In a modification. however, the nozzle E. Fig. 10, and screw may be of conducting material, but the powder discharged passes through n grating H of nonconducting material connected to the cable F. If the powder is dumped by a trough K, Fig. 14, arranged on the side of the metal-dumping trough J. it is charged by passing a charged grid H<1> of non- conducting material. A sand lined or semipermanent mould M<1>, Fig. 16. may have its casing M carthed and the powder supplied by carrier gas in a flexible pipe D<6> passing over pulleys N and connected to a rigid pipe D<9> and an insulated nozzle E<3> adapted to deliver an annular jet.

Abstract: 1,190,590. Wells &c. ROCKWELL MFG. CO. 8 April, 1968 [19 Sept., 1967], No. 16800/ 68. Heading E1F. In a method of cementing a well casing 33 supported by a hanger 30 in an underwater wellhead the surplus cement above and passing outside the hanger is removed by a wash fluid. Apparatus for carrying out the method comprises parts 41 . .43 located between the hanger and a casing extension 36 leading to the surface, the hanger, apparatus and extension being surrounded by a marine conductor 23. After cement has filled the annulus surrounding the casing, torque is applied to the extension to shear a pin (65) and rotate parts 41, 43 to open ports 47 so that wash fluid from the extension flows downwardly between, the parts 43, 42 to remove the surplus cement albove the hanger from the marine conductor. Further rotation of the parts 41, 43 causes surface 56 to engage surface 51 to close the ports. Continued rotation of the parts 41, 43 shears a pin 39 between the hanger and the part 42 so that the apparatus and the extension may be removed from the hanger.

Abstract: 583,261. Indicating and recording devices. BURGESS, A. F. (Anthony Co.). Oct. 18, 1943, No. 17090. [Class 106 (iv)]. The invention relates to an indicating . or recording device for use with an electric welding machine to indicate or record time spent on actual welding. Current is supplied to a welding machine 3 through the wires 1, 2. In series with this welding circuit is a current relay 4 and in shunt with the circuit is a voltage relay 5. The relay contacts 9, 8 for the said relays 4, 5 are included in the separate circuit of the indicating or recording device 10. When a current is passing through the welding circuit, but welding is not taking place, contact 8 is closed while contact 9 is open. When welding begins, contact 9 is also closed and the indicating or recording device 10 is actuated. When welding stops, contact 9 opens and the indicating or recording device stops. If the welding circuit is deliberately short-circuited no false record is made, for although contact 9 moves to the closed position, the contact 8 opens.
