Title: Improvements in air cleaners
IPC: F02M35/08
Filed: 1938-01-21
Abstract: 511,604. Centrifugal gas cleaners. BABCOCK, O., and SMITH, J. R. Jan. 21, 1938, Nos. 2117 and 2118. Convention dates, Jan. 22, 1937, and Dec. 3, 1937. [Class 23] A centrifugal gas cleaner, particularly for use with the carburetters of internal combustion engines and for conditioning air to buildings, has a conical casing 1 surmounted by a perforated cylindrical screen 9 and a cover plate 11 held in place by bolts 10. The flange at the top of the casing 1 which supports the screen also supports a slotted plate 3 arranged to impart a whirling motion to the entering gas, and also the clean gas outlet tube 5. The lower part of this tube passes below the plate 3 to the extent of thirty per cent. of the depth of the casing 1. A dust spout 15 enters a receptacle 16 supported by a cylinder 12 sealed at its upper edge 13 to the casing 1, and the plate 14 is sealed to the cylinder by a rubber gasket 18, and to the spout. To break up the swirl of gases the spout is directed towards one side of the receptacle. An inner conical casing 6 is spaced from the main casing 1 and has a number of elongated slots 7 for the passage of separated dust. The suction in the tube 5 causes air to be drawn in through the screen 9 and whirled. as it enters the separator. Clean gas passes out through the tube 5, and the separated dust passes through the slots 7 and the space between the casings 1, 6 to the spout 15 and receptacle 16. In a modification a filter 19, Fig 5, is arranged in the path of the gas after it leaves the centrifugal separator. Air enters through the screen 20 and passes through the separator 21; the cleansed air passes through the outlet pipe 29 and the dome-shaped filter 19 secured to the screen 20 by clamps 25. In a further modification the separator is inverted and the curved spout is omitted. An annular inlet surrounds the outlet tube at the bottom of the separator; the dust receptacle is arranged over the top of the separator and is held against a rubber gasket by a clamp so that an air tight joint is made.

Title: Laser beam antenna
IPC: H01Q1/36
Filed: 1967-01-16
Abstract: 1,128,881. Aerials. INTERNATIONAL STANDARD ELECTRIC CORP. 16 Jan., 1967 [20 Jan., 1966], No. 2122/67. Heading H4A. [Also in Division H1] In a laser beam aerial a high power laser 1 is coupled to a pulsing means 3. The laser beam is passed through a variable focusing means 2 which is also coupled to the pulsing means 3, so that its focal length is changed in synchronization with the pulsing of the laser. The beam is focused successively at spaced points such as 6, 7, 8 and produces a column of ionized air extending to a predetermined height, which is used as an aerial for a source 4 by means of an electrode 5 connected thereto and immersed in the base of said beam. A ruby or neodymium-doped laser may be used and the focusing means may comprise a fixed lens (10), Fig. 2 (not shown); associated with a movable lens (9) operated by a motor (14) through a rack-and-pinion gearing (11), (12). The pulser (3) controls the motor through a timing means (15), which determines the amount by which the focal distance is changed between pulses. A counter (16) operates a reversing means (17) after a predetermined number of pulses (corresponding to the required height of the ionized air column) and controls the timing means so that the focal distance is returned to its base value, when the cycle recommences. In an alternative arrangement, two lasers (22), (23), Fig. 4 (not shown), with variable focusing means (24), (25) are operated by a common pulser (26). Each variable focusing means has a pivot (37), Fig. 5 (not shown), and is given an arcuate motion synchronized with the extension of its movable lens by means of a rack-andpinion gearing (38), (39) operated by a motor (40). In this way, both lasers are focused together on a succession of points (27), (28), (29), (30), Fig. 4, to provide an ionized column of air. Auxiliary means may be provided to aid ionization such as, the ejection of air which has been subjected to a high tension discharge (Fig. 6, not shown), or the use of ultra-violet light rays or of a beam of microwave energy.

Title: Water-soluble polymeric substituted acrylamides
IPC: C08F8/00
Filed: 1958-01-24
Abstract: Water-soluble polymers containing recurring units of the N-methylglucamide of acrylic acid are obtained by reacting polymethyl acrylate with sufficient N-methylglucamine to convert from 10%-100% of the ester units to amide units and thereby render the polymer water-soluble, the reaction being carried out at a temperature in the range of about 115 DEG -155 DEG C. in the presence of an inert organic solvent, e.g. dimethyl formamide, dimethyl sulphoxide or dioxane.  When the resulting polymer contains unreacted ester units, these may be hydrolysed by treatment with an alkali metal or ammonium hydroxide, or reacted with a low molecular weight amine, e.g. dimethylamine, dibutylamine, N-methyl-N-propylamine, dimethylaminopropylamine or diethylaminobutylamine.  The polymers may be used as soil conditioners, whiteness retention agents for textiles and in applications to paper.

Title: An x-ray camera for x-ray diffraction analysis according to guinier
IPC: G01N23/205
Filed: 1969-01-15
Abstract: 1,255,358. X-ray diffraction apparatus. INCENTIVE RESEARCH & DEVELOPMENT A.B. 15 Jan., 1969 [25 Jan., 1968], No. 2482/69. Heading H5R. An X-ray diffraction camera having an airtight and evacuable casing with an X-ray transparent window houses a crystal holder for a monochromotor crystal mounted on a support plate rotatable about an axis perpendicular to an X-ray beam incident through the window, and a guide rail upon which first and second carriages may be moved radially with respect to the axis of rotation, and with respect to which they may be locked in selected positions, a specimen holder being mounted on one carriage, and a film holder being mechanically coupled to, and having its position determined by, the second carriage. As shown, the X-ray beam 4 enters the evacuable, air-tight camera casing through a window 2, and is incident upon a monochromotor crystal mounted in a crystal holder 33 which is rotatable about an axis M, and which is maintained in a desired position by the urging of a spring 38 upon an arm 37 of the holder which abuts against a micrometer screw 39. The crystal, with a reflecting surface ground to a radius of 2R, is urged against a pair of curved surfaces by spring-biased pins (Figs. 6 and 7, not shown) such that its reflecting surface has a radius of curvature R. A guide rail 45 is adjustably mounted-either pivotally or, as shown, by the provision in the casing of suitable different sets of support screw holessuch that it extends radially from the axis M, two carriages 49 and 50 being movable therealong and lockable in any desired position. The filmholder 5 is freely supported on the rail 45 by the engagement therewith of feet 6, 7, and 8 (see also Fig. 9, not shown) to facilitate its ready removal from the camera, but its position along the rail is determined by the abutment, under gravity, of a projection 51 on its underside with the end of the carriage 49. The filmholder includes a shutter (Figs. 10 and 11, not shown) for permitting a reduced time of exposure of the film to the unrefracted beam. A specimen aperture 52, and specimen holder 53 rotatable by a motor 57, are mounted on the carriage 50, the distance of which from carriage 49, and hence the spacing between the specimen and the film, being adjustable by a screw 58. The entrance aperture arrangement 16 of the camera is formed by four slides movable in perpendicular directions, whereby both the size and the position of the aperture may be adjusted (see also Fig. 3, not shown). The camera as a whole is adjustably mounted on the X-ray tube casing 9 by the cantilever 11 and screw 14, correct alignment of the camera with respect to the beam being determined with a fluorescent screen placed in front of the lead glass window 3.

Filed: 1918-02-12
Abstract: 139,526. Wade, H., (Vereinigte H³tten werke Burbach-Eich-D³delingen). Feb. 12, 1918. Drum recording-apparatus.- A drum recording-device for use in connexion with the blastapparatus of blast furnaces is operated partly by the air pressure on the outlet side of a valve and partly and concurrently by the difference between the pressures on the two sides of the valve. Fig. 1 shows diagrammatically a balanced valve a moved by a piston b affected by the pressure on the discharge side of the valve a. The piston is counterweighted by a weight c and a bucket u, and by means of rods d moves a link i which is mounted on a right-angled sliding piece e, f, g, and forms the hypotenuse of the triangle. The link raises and lowers a rod k carrying a recording-instrument. The record is thus affected in accordance with the cross-sectional area of the passage through the valve a. The air pressures on the two sides of the valve a are transmitted through pipes to a spring-controlled piston l, which, by means of rods o, a curved piece n, and a roller x moving on the piece n, raises and lowers a pin p in a guide f, g, and in the link i, and raises and lowers the link i and rod k in a manner which affects the record in accordance with the pressure-difference in the air pipe. If it is desired to keep the blast constant, the rod k is adapted to operate a watersupply cock q by means of a lever t, and to admit water through the pipe v to the bucket u, which has an outlet cock w adapted to regulate the amount of water retained in the bucket, and consequently the position of the valve a and the quantity of air passing through it.
