Abstract: 1,160,146. Pressure exchangers. BROWN, BOVERI & CO. Ltd. Jan. 26, 1967 [Jan. 28, 1966], No. 3948/67. Heading F1N. In a pressure exchanger wherein hot gas at high pressure supplied to a port 2V is expanded in the cells to cause compression of cold gas supplied through ports 1V and the cold compressed gas leaves through a port 2n for use, the hot high pressure gas Fig. shown and/or the compressed cold gas Fig. 3 (not shown) is branched to a port 2v<SP>1</SP> or (2n<SP>1</SP> ) in communication with cells having previously exhausted the expanded hot gas through a port 1n<SP>1</SP> and reviewed an additional charge of cold gas through a port 1v<SP>1</SP>. The arrangement thus provides a second scavenge in the low pressure zone and enables the pressures of the hot gas supplied and the compressed cold gas to be substantially equal while the expanded hot gas is of greater pressure than the cold gas supplied. Additional scavenges in the low pressure zone of the exchanger can be provided by further branches. The invention is also applicable to through-flow pressure exchangers.

Abstract: 880,066. Water-tube steam boilers; superheaters. BABCOCK & WILCOX CO. Feb. 6, 1958 [Feb. 6, 1957], No. 3999/58. Classes 123(2) and 123(3) A marine boiler has a main furnace 15 and an auxiliary furnace 16 between which is a gas pass 17 constituting a superheater cavity, the pass being separated from the furnaces by spaced tube screens 32, 33 the tubes of which respectively connect lower drums or headers 30, 31 with an upper steam and water drum 18. Gases from the furnace 16 flow through the screen 33 and the pass 17 and are diverted by the lower part of the screen 32 in which the tubes are in contact through the upper part in which the tubes are offset into the top of the main furnace whence they flow with the gases from the main furnace through a bank 20 of steam generating tubes extending from a lower drum 19 to the drum 18, the gases discharging through a stack 21 containing an economizer or air heater 23. A superheater 35 is disposed in the gas pass 17 and is heated by firing oil fuel burners 34 of the auxiliary furnace, the burners being adjusted to regulate the steam temperature. The superheater is arranged so as to give the maximum steam temperature attainable, about 1,000‹F., without undue corrosion of the tubes by products in the oil fuel combustion gases. It comprises two sections 42, 43, Fig. 4, connected in series so that the steam flows from section 42 in the hottest zone to section 43 in the coolest. The sections each consist of externally-disposed vertical inlet and outlet headers 45, 46 and 52, 51 respectively, connected by U-shaped tubes 50, 56, the tubes being arranged in nested sets of three disposed vertically one above another. The superheater tubes are supported by the walls 11, 12 of the setting where they pass therethrough and intermediately by brackets 63 secured to large diameter water-tubes 62. The inlet header 45 and the outlet header 51 are respectively divided by mid-partitions 47, 53 so that steam flows counter to the flow of heating gas both in the upper part 50A of the first superheater section 42 and in the lower part 56A of the second superheater section 43 whilst it flows parallel to the heating gas flow in the other parts 50B, 56B, the two sections being connected by a cross-over tube 57. With this arrangement a uniform balance is maintained between the relative temperatures of the steam and combustion gases to allow high superheat temperatures to be attained without undue corrosion of the tubes 50, 56. In a modification each of the superheater sections is arranged so that three steam passes instead of two are provided.

Title: Improvements in door closing and checking appliances
IPC: E05F3/10
Filed: 1933-02-15
Abstract: 408,782. Door closing and check devices. NEWMAN & SONS, Ltd., W., and NEWMAN, H. G., 268, Hospital Street, Birmingham. Feb. 15, 1933, No. 4581. [Class 65 (i).] A spring-closing and fluid-check device of the floor type comprises a coiled compression spring or springs at one side of a casing, a fluid check device at one side of the spring or springs, and a cam on the door spindle having two cam surfaces on opposite sides of the spindle and in the same horizontal plane, the cam surfaces engaging respectively with a slide which acts on the spring or springs and with the check device or a member connected thereto. The device is shown as applied to a door opening in one direction only, the parts being shown in the position occupied when the door is opened 90‹ anti-clockwise. Two compression springs 16 abut at one end against an adjustable nut 17 on a guide rod 15 and at the other end against a slide 5 running in fixed guides 12 and carrying a roller 13. The check device comprises a cylinder 18, mounted on a pivot 19, and a plunger 11 connected to a bell-crank 10 which is mounted on a pivot at 22 and carries a roller 23 ; the inner end of the cylinder is provided with a ballcheck inlet valve 26 and an adjustable bleed valve of which the stem is shown at 27. A spring 24 surrounds the plunger rod, and bears against the end of the cylinder and the bell-crank. The door spindle 3 carries a cam 4 having one cam surface 8 for engagement with the roller 13 on the spring-operating slide, and an opposite cam surface 9 for engagement with the roller 23 on the check-operating crank 10. When the door is closed, the roller 13 rests in a hollow 8<a> of the cam, and the roller 23 is at the outer end of the straight surface 9. When the door is opened to the position shown, the roller 13 is forced out of the hollow, compressing the springs sharply, on to the surface 8, which gradually increases the compression of the springs up to 180‹ of opening. The cam surface 9 allows the roller 23 to move nearer the spindle 3 as the door is opened to the position shown, and the spring 24 can therefore draw the plunger 11 out of the cylinder ; if the door is opened further, on approaching the 180‹ the roller 23 rides up the left-hand side of the hollow 8<a> thus forcing the plunger a short distance into the cylinder and producing a slight checking effect. When the door is released, the springs 16 acting on the cam surface 8 cause it to close, and in closing from the position shown the cam surface 9 acts on the crank 10 to force the check plunger 11 into the cylinder 18 to cushion the movement. The cam may, if desired, be so shaped that no further movement is imparted to the slide 5 and crank 10 on opening the door beyond 90‹.
