Title: Anion exchanger
IPC: B01D15/04
Filed: 1958-07-25
Abstract: Anion-exchange resins of high capacity are prepared by nitrating and then reducing to the corresponding amino derivatives cross-linked aromatic vinyl copolymers prepared in the presence of at least 20% of an organic liquid which is a solvent for the monomers but not for the polymers such as an aliphatic hydrocarbon, an aliphatic or cycloaliphatic alcohol, an ether or a nitrated aliphatic hydrocarbon. Aromatic vinyl compounds such as styrene, methyl styrene, vinyl anisole and vinyl naphthalene or mixtures thereof cross-linked with, for example, di- or trivinyl benzene, ethylene glycol dimethacrylate or diacrylate, diallyl maleate, divinyl ether, glycol dimaleate, and divinyl ketone can be used and the solvents specified are benzine, white spirit, dodecane, cyclohexanol, methanol, dodecanol, amyl and oleyl alcohol, nitromethane, propane and hexane and diethyl, dibutyl, and diamyl ethers.  Catalysts such as benzoyl and t-butyl peroxides, cumene hydroperoxide, sodium persulphate and azodisisobutyrodinitrile or redox systems may be used and if pearl polymers are required the monomer solutions are suspended in water.  Nitrating agents are nitric or nitric and sulphuric acids, and the reducing agents may be alkaline metal sulphides, disulphides and dithionites, or stannous compounds, in inert solvents such as acetonitrile, cyclohexanone or tetrahydrofurane as the reaction medium.  The products may be alkylated, by for example alkyl halides, dialkyl sulphates, alkylene oxides, halohydrins, polyhalogen compounds or epihalohydrins.

Title: Improvements in or relating to the grinding stones used on wood pulping machines
IPC: B24D7/08
Filed: 1928-08-22
Abstract: 319,469. Akeroyd, H. Aug. 22, 1928. Rasping-apparatus.-A grinding stone for use on wood pulping machines has reinforcing members comprising longitudinally-disposed bolts each passing through a bore provided in the mass or body of the stone and co-operating with an annular or polygonal band or bands located on each of the side faces of the stone. The stone 1, Figs. 1 and 2, is provided on its end faces with grooves 2 into which are inserted steel bands 3 which are preferably shrunk on to the inner faces of the grooves. The bands and stone are bored to receive bolts 5. The stone may be built up of segments, Fig. 3, which may interengage and the band may comprise bent rods 7 which engage over the bolts 5 and are stressed by connecting sleeves 9. A wire rope or a number of strands of wire may replace the rods 7. The bolts 5 may be threaded through eye-bolts which pass radially through the segments and are bolted to a metal sleeve in the central bore of the stone. The grooves 2 may afterwards be filled with cement &c.

Title: Improved thread winding and advancing reels
IPC: D01D10/04
Filed: 1946-08-14
Abstract: 615.287. Thread-advancing reels. FARRAND, T. H., JONES, E. I., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Aug. 14, 1946, No. 24124. [Class 120(ii)] [Also in Group XXX] A thread winding and advancing reel comprises an endless belt which can be bent in the plane of its surface and which is mounted so that it will move substantially in the path of a helix for at least half a revolution and during the remainder of the revolution will be depressed within the surface containing the helical path and, while depressed, be subjected to a lateral movement so that on recovering from the depression the belt will occupy the position from which it commenced its helical movement. As shown, the convolutions A, B, C, D of a thread are carried by a flexible belt formed of cross-pieces 12 (Fig. 3) flexibly connected to chains 1 by rods 13 mounted in rubber sleeves 14. The chains 1 pass around sprockets 9-2 and 9<SP>1</SP>-2<SP>1</SP>, Fig. 2, so positioned that the belt follows a helical path from X to Y in the direction of arrow 11, and then moves laterally around a sprocket 10 below the helical path back to its original position at X. The centres of the sprockets are on lines parallel to the axis of the helical path, but the axes of the sprockets are set at a slight angle to the line of centres so that the belt meets and leaves the sprockets tangentially. Strips 12 are curved on the outer surface and may be composed of wood, metal, synthetic resins or resin-bonded laminates. An alternative construction of belt consists of two pliable bands of polyvinyl chloride (in place of chains 1) to which rigid strips of polyvinyl chloride composition are welded via short sections of pliable polyvinyl chloride composition. In any case, the strips are attached to the chains or bands at such a level that the outer surface of the belt travels at a constant speed, whatever its curvature. Rollers or pulleys may replace the sprocket wheels: rollers may have the cage structure described in Specification 589,979. The rollers, pulleys or sprockets, instead of being set angularly, may be arranged in sets with collinear axes in which case the belt is made free to slip sideways and means are provided for forcing it sideways. These means may consist in flanges fitted to the rollers, or in guiding rollers with their axes perpendicular to the belt surface; or the teeth of sprocket wheels may exert a suitable lateral pressure on the chain links. Where the rollers or pulleys are arranged in sets, the path of the belt may be that of a conical helix. Specification 394,216 also is referred to.

Title: Improvements in the production of lustre effect upon textile fabrics
IPC: D06C15/00
Filed: 1929-08-08
Abstract: 328,175. Wessel, K., (Assignee of Bosshard, A.). March 11, 1929, [Convention date]. Frictional machines.-Lustre effect is produced on textile fabric by drying it by passage over heated rollers G, H, J; charging it electrostatically by passage over insulated heated rollers E, F, rotating at a speed different from that of the fabric; and then submitting the fabric to hot calendering or pressing as by passage between jute rollers B, C heated by heated steel rollers A, D. The rollers E, F may be covered with vulcanite &c. Insulating plates L and heaters M may be provided on each side of the fabric to prevent discharge of the fabric before being calendered. Instead of the electrostatic charge being produced frictionally, it may be applied by conduction to the fabric from an external source.

Filed: 1975-06-06
Abstract: 1506602 Television; noise elimination SONY CORP 6 June 1975 [17 June 1974] 24420/75 Heading H4F A noise eliminating circuit, for video TV signals, Fig. 3A, where a "black" pulse 2 would be interpreted as a sync. pulse, and particularly for video signals in magnetic recording and playback apparatus, compises a low pass filter 13, Fig. 2, not shown, for the low frequency band components, Fig. 3B, of the video signal, a high pass filter (14) for the high frequency band, Fig. 3c, a clipping circuit (30), connected to said high pass filter, which clips signals over a predetermined black level 21, and a mixer (22) for combining the outputs from the low pass filter and the clipping circuit i.e. for adding the waveforms shown in Figs. 3B and 3E to produce the substantially noise free shown in Fig. 3F. The circuit may further comprise a noise limiter (16) which eliminates high frequency noise S D  between levels 17. The clipping circuit comprises in series a fixed and a variable resistor (18a, 18b), and an earthed diode (19) in parallel with the variable resistor. The addition of the high and low band components introduces overshoot portions such as 23, 25 i.e. the change from a black to a white level is accentuated, and the clarity of the picture is enhanced. The circuit therefore acts as a "crisping circuit" or as an "aperture correction circuit". Emphasis or deemphasis circuitry may also be provided. The invention may also be used when a negative video signal is used.
