Title: Improvements in or relating to centrifugal pumps
IPC: F24D19/08
Filed: 1924-06-26
Abstract: 218,995. Nash Engineering Co., (Assignees of Jennings, I. C.). July 9, 1923, [Convention date]. Pumping-machines.-Pumping sets for use in vacuum steam heating systems or in connection with paper making machines, have rotary air and water pumps with separate housings bolted together end to end and a single driving shaft. The air pump housing 17 is supported by longitudinal flanges 20 formed on the main body of the housing and having out-turned lower end portions as shown in Fig. 5. The shaft 28 passes through the hub 29 of the rotor so as to permit relative axial movement. The inlet pipe 30 is part of the main body 21 of the casing and the air passes from the pipe through a slot 32, Fig. 4, into the head portion 25. This part has an enlarged sleeve 33 with a stuffing box 34, Fig. 3, at its outer end for the passage of the shaft. Inlet and outlet openings for the rotor are provided at each end of the casing and the pump discharges into the atmosphere through the pipe 37. The main part 12 of the water pump housing consists of the volute casing 47, the wall 46 of the impeller casing with the cylindrical wall 49. the discharge pipe 53 and the inlet pipe 52. The other part consists of the head plate 54 with the impeller casing wall 55 and a wall 65 forming a chamber 66 round the bearing connection in the head plate. Any air that leaks through the packing 67 is guided by the chamber 66 to the top of the pump, through the vent 70 and the pipe 15 to the tank 10. The chamber of the air pump through which the shaft 28 passes on the right-hand side is under suction and there is no tendency for air to leak into the water pump on that side. The water that passes through serves to furnish the supply for the air pump. The surface 50 of the water pump casing fits the surface 51 on the adjacent end of the air pump casing and these two parts are held together bv cap screws. The ends of the shaft are carried in ball bearings supported by brackets consisting of arms 73 upon rings 74 secured to the pump casing. The inner ball race 78 is held by a nut 79 against a shoulder on the shaft. The outer race 80 of the left-hand bearing is allowed slight axial movement as it is not tightly held by the collars 76, 77. The outer race of the right-hand bearing 81 is held bv the ring nuts 85 which have spaced holes in their outer sides for turning and locking. When the races are properly adjusted' the pins 93, 94, Fig. 6, are inserted and the caps 87, 89 are secured by the screws 105. A tank 10 receives the water and air through suitable piping; the water pump draws its supply through the pipe 13 near the bottom of the tank and air is drawn through the pipe 16.

Title: Improvements in and relating to apparatus for supplying gases to respirators for breathing purposes
IPC: A62B9/02
Filed: 1945-06-18
Abstract: 591,530. Fluid - actuated valves. HODGKIN, A. L., and MATTHEWS, B. H. C. June 18, 1945, No. 15498. [Class 135] [Also in Group VI] An automatic regulator controlling the supply of gas to a respirator comprises a reservoir to which gas is continually fed and which is provided with means for expelling its contents to the respirator through a spring loaded valve, which remains closed when the pressure difference across, it is that between reservoir and atmospheric pressure, but will open when the pressure on its delivery side is lowered by a small amount, and which has a self servo-action whereby the pressure difference between the reservoir and atmosphere will hold it open until the pressure difference across the valve falls to zero or a relatively small valve. As shown in Fig. 2, synthetic resin casings 10, 11, enclose flexible bag 18 compressed by plate 19, which is attached by springs 22 and rocker arms 20 to valve body 26 and casing 11 respectively. Springs 22 tend to exert pressure downwards on plate 19 and to hold arms 20 in V-shaped sockets. Upward movement of plate 19 is limited by stop 29. Gas flows continuously from an inlet pipe through an apertured ferrule to the bag and passes through a similar ferrule 44 to valve chamber 27 formed with an extension 27a into which valve body 26 fits. Ring 31 forms a gas-tight seal between extension 27a, valve body 26 and a collar 32 on the upper end of a gauze filter 33. Screwed into valve body 26 is a seating tube 34, slotted at 35, and having a closed end in which is adjustably anchored a spring 37 attached to a mica disc valve 38, which seats on tube 34 and also on cup 40 fitting into the valve body 26. The space under valve 38 between seating 40 and 39 is vented to the interior of the casing through ports 41. The upper edge of valve body 26 communicates with outlet pipe 16. Casing 11 is provided with a gauze screened vent 30. Inhalation causes the valve to trip, when the bag pressure is applied to the whole of the underside of the valve, which will not re-seat until the entire contents of bag 18 are expelled to the inhaler. In an alternative, Fig. 7, the valve body 26a is extended downwards to form a pocket enclosing spring 37, and apertures therein (not shown) allow gas to pass to the valve 38. Cup 40a is formed integrally with valve body 26a, and passages 41a vent the space between seatings 40a and 39a to the interior of the casing. The seal between valve body 26a and extension 27a of the valve chamber is formed by ring 53.

Title: An improved process for the manufacture of iron and steel directly from the ore, and improved apparatus therefor
IPC: C21B13/00
Filed: 1918-10-02
Abstract: 158,523. Basset, L. P. Oct. 3, 1917, [Convention date]. Extracting.-Iron ore is reduced by means of the exact quantity of carbon necessary, or by means of carbon monoxide, and the resulting spongy iron is melted in a. flame consisting of carbon monoxide produced by the combustion of finely-divided carbon or other material such as crude petroleum, the proportion of petroleum to air being so determined that at the temperature employed the hydrogen remains free while the carbon burns to carbon monoxide. The richness of the flame in carbon or oxygen may be slightly varied in order to carburize or refine the metal. The ore mixed with carbon may be reduced in externally heated vertical or other retorts b, Fig. 1, from which the spongy iron is discharged to a reverberatory furnace c fed with flour carbon and air through a tuyere e, part of the carbon monoxide which is produced being utilized for heating the retorts b and part for heating the air supply for the tuyere e. After the metal has been melted in the furnace c, the slag is run off and the metal is finished with additions of carbon, manganese, &c., or by means of an oxidizing-flame- The retorts b may discharge into a passage leading to a separate reverberatory furnace or into a vessel in which the metal is cooled before being admitted to the furnace. The reduction of the ore and the melting of the metal may be effected ia succession in a single reverberatory furnace c<1>, Fig. 2, connected with air-heating regenerators n, o, and heated by tuyeres e, e<1>, the direction of the air and gases being reversed periodically; or two furnaces arranged side by side and worked in series in opposite directions alternately may be used ; or four furnaces may be arranged in a cyclic series. In further modifications, the spongy iron may be produced in a rotary furnace and charged into a melting-furnace. The Specification, as open to inspection under Sect. 91 (3) (a) states also that the method may be applied to the treatment of scrap with or without the addition of new spongy iron. This subjectmatter does not appear in the Specification as accepted.

Abstract: 897,663. Can openers. BURGESS VIBROCRAFTERS Inc. May 6, 1960 [May 8, 1959], No. 16099/60. Class 66. A can opener operated by an electric motor (not shown) comprises a toothed wheel 30 for rotating a can 33 to be cut open by a blade 38 which is pivoted into engagement with the can, through intermediate mechanism, by lowering a handle 53, the resistance force applied to the blade 38 when it is pressed on to the can operating an electric switch so causing the wheel 30 to rotate the can, the switch connection being broken only when sideways pressure on the blade 38 caused by cutting the rotating can has ceased. The handle 53 carries rigidly between its arms 54 a shaft 59 having a throw 62 which operates on spaced lugs 63 of a follower plate 64 provided with a horizontal slot 69. The front panel 22 of a housing 21 for the can opener has a curved slot 52, a similar slot 49 being formed in a plate 36 which is screwed to the panel 22 and supports the cutter blade assembly. A stud 41 with enlarged rear portion 51 holds the blade 38 between guide shoulders on a crank 44 pivoted on a pin 46 journalled in the plate 36, and passes through the slots 49, 52 ,and 69. With the arms 54 of the handle 53 raised as in Fig. 6, the throw 62 of the shaft 59 holds the follower plate 64 at the top of its travel in a recess 65 formed in the rear face of the panel 22. As the handle is lowered, the blade 38 pivots downwards to touch the top of the can 33 which transmits a resistance force through the stud portion 51 to cause the follower, plate 64 to pivot slightly about the stud portion 51 thereby closing switch contacts 77, 82 by the pressure of a lug 67 rigid with the follower plate 64, Fig. 7 (not shown). Thereupon the electric motor is actuated to drive the wheel 30 and so rotate the can 33 causing the blade 38 to first puncture and then cut out the can lid. As the blade 38 sinks into its cutting position the stud portion 51 pivots to the position shown in Fig. 8, carrying with it the crank 44. When the can lid is severed the force exerted by the stud portion 51 on the follower plate 64 is relieved and the electrical circuit is reopened by a spring which moves the lug 67 on the plate 64 away from the switch. The cut out lid of the can is held by a magnet, Fig. 2 (not shown) on the underside of the handle 53.
