IPC: F04B49/00
Filed: 1996-01-04
Abstract: PROBLEM TO BE SOLVED: To use an outlet regulating valve in common without arranging a piping which is arranged in the downstream of each check valve and a water feed stopping valve by arranging the outlet regulating valve between a water feed pump outlet header which is common to a turbine driving water feed pump and a motor driving water feed pump, and a high pressure water feed heater. SOLUTION: An outlet regulating valve 5 is arranged between a water feed pump outlet header which is common to a turbine driving water feed pump 7 and a motor driving water feed pump 2 and a high pressure water feed heater 6. The valve 5 is used in such a way that one is closed and the other one is opening exchanged by respective outlet valves 4, 9 of the pumps 2, 7, and thereby, the valve 5 is used in common without arranging a piping which is arranged in the rear of each check valve 3, 8 and a water feed stopping valve. It is thus possible to obtain good effect economically.

Title: Web carrying roller
Inventor: DANIERU SHII RIOI
IPC: B65H20/02
Filed: 1993-01-04
Abstract: PURPOSE: To provide a web carrying roller for improving driving force between a roller and a web by discharging air from a part between the surface of the roller and the moving web. CONSTITUTION: This web carrying roller is provided with the surface provided with almost spherical recessed parts 22 and plural flat parts 30 and many of the recessed parts 22 are overlapped with each other and form mutually connected grooves occupying at least 50% of the surface area of the roller. The depth of the recessed part 22 is deeper than about 0.0254 mm but shallower than about 0.0508 mm. The flat parts 30 occupy at least 20% of the surface area of the roller. By appropriately selecting the ratio to the surface area of the roller of the grooves and the flat parts and the depth of the recessed parts 22, the air is released from the part between the roller and the web without forming regular air discharge patterns on the roller surface. Thus the driving force characteristics of the roller are improved.

Title: Improvements relating to mixing valves for controlling the mixing of hot and cold fluids
Inventor: MEYNELL LIONEL CHARLES
IPC: F16K11/16
Filed: 1959-01-03
Abstract: 885,752. Valves. MEYNELL & SONS Ltd. Dec. 9, 1959 [June 3, 1959], No. 291/59. Class 135. A mixing valve has a base 10, Fig. 2, incorporating hot and cold water inlets 11, 12 and a mixing chamber 104 with a bi-conical valve 14 that controls the entry of cold and hot water into the top and bottom, respectively, of the chamber; the valve 14 is of resilient heat-resisting material, e.g. synthetic rubber. The chamber communicates via passages 105 with a distributing chamber 212 under the control of a lift valve 192 having a lost-motion connection with the valve 14; the chamber 212 has two outlets in the base 10, only one of which is used, the outlets opening to the chamber through arcuate ports. The head 22 is turned to unseat the valve 192 whilst a spring 18 keeps the valve 14 in the position shown so that cold water only enters the chambers 104 and 212; continued rotation of the head 22 causes the bottom of the stem 194 of valve 192 to lift valve 14 and open the chambers to the inflow of hot water. Manipulation of the head 22 enables the amount of hot and cold water entering the chambers to be adjusted whereby the temperature of the outlet water is determined. In each inlet is a safety valve 231, 232, both being mounted on a common stem 23 and the area of the valve in the cold water being greater than that in the hot water inlet so that in the event of failure of the cold water supply the valve 231 will seat and prevent any further supply of hot water to the mixing valve.

Abstract: 245,476. Gilchrist & Co., (Assignees of Graham, W. C., Rumsey, H. S., and Wetherbee, A. U.). Jan. 5, 1925, [Convention date]. Separating by gravity.-Sediment settles from a liquid caused to pass slowly through a chamber and is removed in substantially the same direction as that of the flow of the liquid, liquid and sediment being discharged separately and no sediment being returned to the chamber. A container 10, Fig. 1, is provided with a number of shelves 18 with depending aprons 19 and central apertures 20. Fluid under treatment is supplied by a pipe 15 to an upper reservoir 14 and passes downward through the apertures 20. Clear liquid passes away from each compartment through pipes 21 while solid matter settling on the shelves is pushed outward by bladed sweeps 24 on a rotating shaft 23 and falls to the lowest compartment from which it is discharged at the centre. The clear liquid and the sludge thus travel in the same direction in each compartment. Gases and scum rise at the centre, the scum flowing over a baffle 16 to outlet 17. An auxiliary partition 25 with a small central opening is provided in the lowest compartment. Fig. 4 shows apparatus with shelves 34 inclined inwards and rotating with the shaft 23, the sweeps 35 being fixed. The fluid passes downward outside the trays, clear liquid is drawn off at the centre through apertured pipes 36, the solid matter settling on the shelves being pushed to the centre and directed downwards by conical walls 37. The Specification as open to inspection under Sect. 91 (3) (a) describes also a form with doubly-sloping trays 39, Fig. 5, (Cancelled), clear liquid being discharged through pipes 44 and scum through pipes 45. This subject-matter does not appear in the Specification as accepted.

Abstract: 334,476. Muller, W. C. Jan. 18, 1929, [Convention date]. Fixed-abutment type; valves, distributing and cut-off; governing and regulating; discharge and suction pipes and passages for pumps, blowers, and exhausters.-In a rotary pump or motor for a hy draulic transmission gear a gyratory piston 7 is connected to a stationary casing 1 by vanes 5 which slide in segments 6a in the piston and oscillate in circular seatings 4b in the casing. A driving shaft 12 is fixed to a rectangular block 11 which, in the case of a pump, through roller bearings 13, turns an eccentrically-disposed bush 9 and the bush causes the piston 7 to gyrate. Roller bearings 8a separate bush and piston. The eccentricity of the bush can be varied by means of a handlever 15 which through a sliding-rod 17 and a bell-crank lever 18 moves a pin 14 which bears on each end of a rectangular slot 10 in the bush 9 The end of the lever 15 is bifurcated and straddles the pin 17 which is free to rotate with the bush 9. Fluid to be pumped enters a circular groove 24 by way of a passage 23 and then through ports 30 in a camoperated distributor-ring 26, Fig. 3, passes to conduits 32 to the expanding pumping chambers 33a. Pins 28 in pockets 29 prevent the ring 26 from rotating. Fluid is pumped from the contracting chambers 33b back through conduits 32 to ports 30 and then delivered to a circular groove 34 and outlet 35. In an alternative fluid-distribution system rotating disc is used in place of the distributing-ring and two semi-circular slots of different radii alternately connect the conduits 32 with the inlet and outlet grooves 24 and 34. The shaft 12 may remain stationary and the casing 1 revolve. Fig. 8 illustrates a system embodying a pump 48 and a motor 50 power being supplied to the pump through a coupling 47 and taken from the motor by means of a coupling 50a. Make-up-oil is supplied from a tank 52 by means of a gear-wheel pump 53 through non-return valves 56. An adjustable relief valve 54b is provided. Fluid leaking along the pump and motor shafts is drained away through pipes 57 and delivered to the tank 52 by a pump 58.

Abstract: 125,917. Brown, J. H., and Mellor, G. A. Jan. 6, 1919. Vaporizers, external.-Comprises a carburettor in which the primary ai. and a preliminary mixture pass through U-tubes arranged in an exhaustheated casing. The casing A contains a series of U-tubes B<1> which open into two chambers C, D. One of the tubes is extended at both ends at E<1>, J, and a small quantity of air enters E' through ports E<2> and passes to the other end J. This end is surrounded by an annular fuel chamber H<1> which communicates with the atmosphere through a port H<5> and with the tube through ports J<1>, so that a rich mixture is drawn into the tube and passes upwards, escaping through ports J<2> and channels H<3>, past a suction-actuated valve H<4> into the chamber C. From this chamber the mixture passes through the U-tubes to the other chamber D where more air is admitted through a suction-actuated valve F<2> and ports F<3> controlled by a valve G. The final mixture is controlled by a throttle-valve (not shown). The valve G regulates the ports E<2> for the initial supply of air. The fuel valve may be operated by the throttle-valve or by the valve G; in the latter case, as the valve G opens, the fuel valve is first opened and then closed to a pre-determined minimum. A suction-actuated governor may control the throttle and fuel valves.

Abstract: 833,339. Electric tests. ROSCOE, E. March 15, 1957 [Jan. 6, 1956], No. 507/56. Class 37. Apparatus for testing phase-to-earth loop impedance of A.C. mains comprises a switch 18 to connect in series, between phase and earth, the contacts 16, 17' of a high-speed circuitbreaker device and a non-inductive selected resistor R 1 -R 4  ; voltage-sensitive display means 31 supplied with a voltage derived from that developed across the selected resistor and adapted to operate when this voltage exceeds a minimum value; and means 24 for tripping the circuit-breaker within one cycle of the supply frequency after operation of the display means. The apparatus is mounted in a container 11 with terminals 12, 13, 14 for connection to phase, neutral and earth respectively; and voltmeter 37, switchably connected between terminals 12, 13 or 12, 14, provides a polarity check for the correct connections to terminals 12 and 13. The phase conductor is earthed through switch 15, contacts 16, 17, and either a lamp 22 or one of the resistors R 1 -R 4 . The trip coils 161, 171 are connected to neutral through D.C. relay contact 23 having its winding 24 shunted by rectifier 26, and slugged to operate after 1 ¢ cycles of the supply frequency. A proportion of the voltage developed across the selected resistor is fed from potentiometer tapping 29 to the grid of thyratron 31 which is initially adjusted by applying 120 volts R.M.S. to test points 36 and setting slider 29 so that the thyratron just strikes. A voltage drop of 120 volts R.M.S. across any chosen one of resistors R 1 -R 4  causes the thyratron to strike, and thus indicate, for 240 v. mains, a maximum phase-to-earth impedance equal to that of the chosen resistor. The slider 29 is calibrated for various values of mains voltage.
