Abstract: 640.964. Polishing mops. COOPER & CO. (BIRMINGHAM), Ltd., and STOKES, F. P. Jan. 20, 1948, Nos. 1655 and 12289. [Class 19] A polishing mop is made of a number of layers of woven fabric formed from a strip cut from the fabric with one straight edge at an angle of substantially 45 degrees to the warp and weft threads of the fabric and having projecting from the other edge a series of tongues or projections, preferably of truncated triangular outline separated by gaps or notches of similar outline. The strip is folded at the base of each gap or notch so that the initial edges of adjacent tongues or projections meet or preferably slightly overlap and the strip is brought into the form of a disc. Any desired' number of these discs are superimposed and stitched together by annular or spiral lines of stitching or by a combination of these. If desired an individual disc of fabric of smaller diameter may be applied to each side of the assembled disc before; stitching. In cutting the strips from a length of fabric two oppositely facing strips can be cut simultaneously and the gaps or, notches in one edge of one strip form the tongues or projections on the adjacent edge of the other strip so that no material is wasted. If desired, the length of bias-cut fabric may be wound on a cylindrical former of suitable diameter and while on the former may be cut into two oppositely facing strips. Each wound strip is then removed from the former and the ends of the tongues or projections are drawn together and the fabric is simultaneously folded to bring it into the form of a disc with the inclined edges of the projections overlapping. In the Figures, a sheet of fabric a, Fig. 1, is cut into strips b by cuts indicated by lines c which are at angles of 45 degrees to the longitudinal edges of the sheet and to the warp and weft threads of the fabric which are indicated by the lines d. The bias strip is cut into identical strips by zig-zag cuts f, Fig. 3, to form two strips g, g. Each strip g is then folded at the base of each gap or notch so that the inclined edges of adjacent tongues meet or preferably overlap slightly and the strip is brought into the form of a disc j, Fig. 6, the number of superimposed layers of fabric in the disc depending on the length of the strip. In an alternative method of operation the strip b is wound in successive layers round a cylindrical former and cut into two strips g, Fig. 4. while on the former. Each of these is then slid off the former without being unwound and the ends of the tongues or projections h are drawn together and the fabric is simultaneously folded to bring it into the form of a disc j. Any desired number of discs are then assembled together to form a mop of the required thickness and are stitched together. Usually an undivided disc of fabric of smaller diameter is applied to each side of the assembled discs before stitching.

Filed: 1941-02-17
Abstract: 545,590. Heat transmitting media. HOUDRY PROCESS CORPORATION. Feb. 17, 1941, Nos. 2142/41, [Convention date, Feb. 17, 1940], 2144/41, 2145/41 and 2146/41, [Convention dates, Sept. 27, 1940]. [Class 64 (ii)] The low-melting properties of heat-transfer salts consisting of alkali metal nitrates and nitrites are maintained by keeping constant the ratios of nitrate to nitrite ions in the mixture. This may be done by drawing off a portion of the mixture, submitting it to reduction and returning the treated portion to the system. The proportion of nitrate should be maintained between 10 per cent. and 50 per cent. The alkali content is preferably kept between 0.2 per cent. and 2 per cent., calculated as NaOH. Hydrogen, hydrocarbons, a hydrocarbon-hydrogen mixture or ammonia gas may be used for the reduction. If nitric oxide is used to neutralize the alkali it also acts to convert nitrate to nitrite. If nitrogen dioxide is used for the neutralization equal amounts of nitrate and nitrite are formed from the alkali. Nitric acid, N203, N205, mixtures of nitrogen oxides, or silica, alumina or silicaalumina gel may also be used. Reduction with hydrogen may take place in the conventional packed column which may be inclined and rotating, or in a chamber R, Fig. 2, in which the hydrogen is passed up through a removable perforated plate 31 of unglazed porcelain with a depending annular flange 32 to form a liquid seal in the annular well 30. To reduce oxidation as far as possible a low partial pressure of oxygen in the atmosphere in contact with the salt should be maintained. Usual additions such as phosphates and chromates may be made. The mixture may be used in apparatus for the control of the temperature of a catalyst or for cracking petroleum hydrocarbons. According to the Specification as open to inspection under Sect. 91 only, the composition may be maintained by mere addition of the quantity required. This subject-matter does not appear in the Specification as accepted.

In separating carbon dioxide and water vapour from air prior to its liquefaction in a gas refrigerator 34, Fig. 3, by condensation in the solid phase on metal gauze 23 through which the air is passed and which is cooled by forcing liquid air at its boiling point up a plurality of spaced vertical metal tubes 22 connecting lower and upper chambers 24, 25 accumulation of acetylene in the boiling liquid air is limited to below the explosion concentration by continuously withdrawing liquid air from the chamber 24 and replacing it with colder and relatively pure liquid air thus replacing the loss due to vaporization in tubes 22 and that due to withdrawal. As shown liquid air is withdrawn from chamber 24 through a duct 36 containing a heater 37 and the vapour so produced acts as a bubble pump and forces liquid air containing acetylene through an evaporator 38 and thence through a heat exchanger 39 serving to cool incoming air. In operation the so-purified air having traversed gauze 23 and entered the upper end of chamber 25 as indicated by flow arrows is drawn from chamber 25 through ducts 20, 33 into the condensing chamber of the refrigerator 34 which discharges liquid air through duct 33 into a container 28 having an aperture 29 opening into the liquid space of a surrounding container 27 which is connected by a duct 26 to the chamber 24 and has a product liquid air delivery duct 31 which serves to limit the height of liquid in containers 27, 28. The unvaporized portion of the liquid air forced up tubes 22 and which is effected by bubble pump action is returned through duct 20 to container 27 and duct 26 to the chamber 24. In a modification incoming air traverses a plurality of metal gauzes 41, Fig. 5, each cooled by liquid air ascending tubes arranged round 4 common supply containers 42, 43 and acetylene containing liquid air is withdrawn from a common lower chamber through a bubble pump pipe 55 leading to an overflow compartment 56 of a product collecting chamber 48 into which passes the uptake tube 46 of a bubble pump, the downtube 45 of which is supplied from the refrigerator 53 through a tube 52 and an overflow trough 54.

Filed: 1936-01-24
Abstract: 467,453. Sifting-apparatus. SIMPSON, L. E. Jan. 24, 1936, No. 2318. [Class 117] In sifting-apparatus of the kind in which the sieves have imparted to them a gyratory movement in a plane at a small angle to the plane of the sieves, the angle of movement is out of parallel with both the longitudinal and transverse directions of the sieve surface to an extent sufficient to cause the material to pass over the sieves in a substantially straight line from the feed to the discharge end. In the arrangement shown in Fig. 3, the sieve 10 is slung from an overhead support by links 11 and is normally horizontal. An eccentric 12 drives the sieve and is disposed so that its axis makes a slight angle with the longitudinal and transverse axis of the sieve. Alternatively the sieve may be inclined along one axis and the driving shaft is at angle to the other axis. Fig. 10 shows the application to a sieve in which the gyratory movement is applied to one end of the sieve of which the other end is constrained to move in a substantially straight line. The sieve frame carries two superposed sieves which are cleaned by loose balls 32 contained in compartments under the sieves. In the case of sieves actuated by a rotary unbalanced weight, the angularity of the plane of movement can be secured by arranging the screen at a compound angle in the frame or by constraining the movement by a heavy spring. Alternatively guides may be provided either with the eccentric or reaction type of drive.

Abstract: 1,010,958. Change-speed control. FORD MOTOR CO. Ltd. June 12, 1964, No. 24411/64. Heading F2D. A manual gear-shift lever 4 is universally mounted on the rear la of a gear-box housing 1 and controls the selector mechanism through two substantially axially movable rods 2, 3. Axial movement of the rod 2 rotates a selector arm (not shown) into engagement with one of three selector rods (not shown) and axial movement of the rod 3 moves the selected selector rod axially to engage the respective gear. The gear lever 4 is pivotally mounted on a stud 9 supported on a bracket 8 which is pivotally mounted about an axis A in a second bracket 5 which is bolted to the rear of the gear-box housing. Bracket 8 is fast with a stud 6 carrying a finger 10 which engages a notch in an arm 11a of a bell-crank lever 11 which is pivoted about a stud 14 and has its other arm connected to the rod 2. Pivoting of the gear lever about the axis A rotates the bracket 8 and stud 6 and consequently through the bell-crank lever 11 shifts the rod 2 substantially axially. The lower end 4c of the gear lever 4 is located in a slot in one arm of a lever 12 which is pivoted at 13 to the bracket 5. The slot extends parallel to the stud 9 so that pivoting of the gear lever about the axis. A will not cause the lever 12 to move. Pivoting of the gear lever about the stud 9 rotates the lever 12 about the pivot 13 and consequently shifts the rod 3 substantially axially since it is connected to the lower end of the lever 12.
