Title: A Separator and Filter for Purifying Water for use in Steam Generators and for Manufacturing Purposes.
Inventor: AUSTIN WILLIAM RITCHIE
IPC: B01D21/00
Filed: 1918-06-28
Abstract: 124,130. Austin, W. R. June 28, 1918. Separating by gravity: filters having sheet filtering-materials.-Feed-water for steam generators is freed from oil and sediment in a settling- device and then passed through filters. The water passes through a valve V into a spirally coiled pipe C or other tortuous passage arranged within a casing SC. The pipe C is immersed in water in the casing and is formed with ports above and below through which oil and sediment escape. From the pipe C the water passes to a set of filters F, arranged in parallel in separate chambers, and furnished with valves V<1>, V<2> so that any one may be cut off for cleaning. The filters F are formed of fabric stretched on polygonal lantern-shaped frames. The frames are supported on central exit pipes SP. Steam may be blown into the filters to clean them.

Title: Method and apparatus for carrying out catalytic reactions
IPC: B01J8/06
Filed: 1929-04-06
Abstract: 310,956. Selden Co., (Assignees of Jaeger, A. 0.). May 4, 1928, [Convention date]. Catalytic apparatus.-In apparatus for conducting exothermic catalytic gas reactions wherein the catalyst tubes are cooled by a liquid bath, the liquid is not permitted to boil in the bath itself but is withdrawn to a region of lower pressure where it partly evaporates and is thereby cooled. The cooled liquid, together with the condensed vapour thereof is recirculated to the bath. As the preferred liquid is mercury or a mercury alloy the reduction of pressure is conveniently effected by raising the liquid to a higher level. The temperature of the bath may be controlled by varying the pressure in the evaporating zone. In the embodiment shown in Fig. 3 the catalyst 13 is placed in annular spaces cooled on the inside by the reaction gas and on the outside by the bath. Liquid from the bath rises through the pipes 8 to the evaporation space 7 which is provided with a reflux condenser 10; the cooled liquid returns by the pipe 9 to the bath. Circulation may be assisted by mechanical means, or by heating the rising pipes 8. The apparatus is particularly applicable to organic oxidations and reductions.

Title: Improvements in combined electric switch and plug connectors
IPC: H01R13/71
Filed: 1923-04-23
Abstract: 208,081. General Electric Co., Ltd., and Read, F. April 23, 1923. Plug connectors combined with electric switches. Two contact carrying discs are coupled together on inserting the plug which latter is turned to close the circuit and retained in this position by a detent engaging a pin of the plug; upon withdrawing the plug the lower disc is released and opens the circuit and the detent and upper disc are then released in turn. The plug has three pins, one 15 longer than the others 16. The pins enter bushed holes in an upper disc 3 carrying contact arms 12 in connection with the bushes 13 and normally pressed into two spring jaws 10 on a second disc 2. The pin 14 enters a hole 18 in the disc 2 and when the plug is turned both discs are carried around so that contact blades 9 connected to the contact jaws 10 on the disc 2 are inserted into terminal jaws 5 on the base and close the circuit. Springs (not shown) controlling each disc 2, 3 are strained in this movement and a spring controlled detent 7 on a part 6 and arranged between the discs engages the pin 15 and locks it and the discs against rotation in the position shown in Fig. 3 until the plug is withdrawn. Specifi. cation 136,006 is referred to.

Title: Conversion of steam power plant with geared turbines
IPC: B04B7/12
Filed: 1935-04-10
Abstract: 452,671. Geared turbines; motor power plant. BAUER, G., 82, Mittelweg, Hamburg, Germany. April 10, 1935, No. 11136. Convention date, April 11, 1934. [Class 110 (iii)] In a geared turbine plant, which may include a reciprocating engine exhausting to a low pressure turbine, a high pressure turbine with its gearing is structurally combined with the geared turbine so as to lie in plan substantially within the plan of the main gear casing. The arrangement may be applied to the modification of existing plant. The high pressure turbine is supplied from a separate source of steam. Figs. 2 and 3 show a lay-out in which a turbine 1 and a low pressure turbine 2 drive a main gear 9 on a power shaft 10 through double reduction gearing. The existing cover of the gear box is replaced by a cover 16 in which is mounted an extreme pressure turbine 11 together with double reduction gearing 13, 14 for connecting it to the main gear 9. The turbines take steam in series. Steam from the high pressure turbine may be diverted to other consumers by a valve c. Figs. 6 and 7 show an arrangement in which an exhaust turbine 18 receives steam from a reciprocating engine to the shaft 22 of which it is connected by double reduction gearing. The added high pressure turbine 26 is carried by a replaced portion 25 of the gear housing, and its pinion 27 meshes with a gear 28 on the shaft of the turbine 18. The high pressure turbine exhausts to the reciprocating engine, and it may be arranged to drive the main gear through independent double reduction gearing. In replacing part of the gear housing, certain gear wheels may be replaced. The Specification as open to inspection under Sect. 91 comprises also a statement that a hydraulic coupling, which may be emptied, may be interposed in the transmission system of the high pressure turbine. This subjectmatter does not appear in the Specification as accepted.

Title: Deposition of boron on metal filaments
IPC: C23C16/54
Filed: 1967-03-09
Abstract: In the making of metal-cored boron filaments by continuously depositing boron on a fine wire of tungsten or other metal, such as high-tensile steel, molybdenum or tantalum, the formation of an undesired metal boride is avoided by first coating the wire with boron nitride.  The boron nitride may be applied as an aqueous suspension to the wire prior to at least the last drawing operation in its production, in which it acts as a lubricant, or may be applied to the wire after drawing is completed and the graphite lubricant used is removed.  Boron is applied to the coated wire by thermal decomposition of a boron halide in a hydrogen atmosphere, or by thermal decomposition of a boron hydride.

A method of making a paperboard box from a blank comprises mechanically applying a tape strip to a first edge of a moving flat blank with the tape strip projecting over said edge, folding the moving blank to present the taped edge to a second edge of the blank with the projecting portion of the tape strip overlapping the second edge, and securing the tape strip 36 to the second edge to form a foldable connection between the first and second blank edges 16, 18, Fig. 6. The tape is fed from a reel through cutters (56, Fig. 7 not shown), and moistening device (62) which moistens half the tape width, to the blank (10) moving on a belt. The projecting part of the tape is then moistened by a further moistening device (72) before folding. The tape may be on the inside of the box and the sealing of the tape to second edge may be deferred until the folded blank is under the control of the squaring equipment by bending the projecting portion of the tape out of the plane of the blank edges during the moistening of said portion.
