Title: Improvements in cylinder grinders
IPC: B24B23/08
Filed: 1927-02-28
Abstract: 281,905. Johnson, J. Feb. 28, 1927. Round holes, enlarging and trueing; gauges.- A machine for grinding cylinders of automobile engines without removal thereof from the chassis, consists of a base 5 adapted to be secured to the cylinder and carrying guide rods 6 to which is secured a support 11. The base has a central opening in which is mounted, on ball bearings, a turntable 13 rotated through worm gearing 18, 20 either by a hand wheel 21 or an electric motor 23, the switch of which is adjustable on one of the rods 6. Passing through the table 13 is a shaft 15, and pivoted at 28 to the shaft is a bar 27 which lies in a slot 29 in the shaft and may be moved therein about the pivot by a screw 35 actuated, through worm gearing 39, 41, by a knurled head 43 on a rod 40. The bar 27 carries at its upper end an electric motor 30 driving a shaft 31 passing down a recess in the bar and having at its lower end a grinding- wheel 33; the shaft 15 carries a U-shaped portion 34 in which the wheel 33 is located, and extends downwardly beneath the. portion 34. A forked member 45 is secured to the shaft 15 and at its upper end carries an insulated current collecting ring 47 for the motor 30, a stub shaft 50 connecting the member 45 to a screwed shaft 51 having a keyway therein. The shaft engages a gear wheel 53 having a tongue engaging the keyway, and the shaft also engages an internally screwed gear wheel 55, and gear wheels 56, 58 on a shaft 57 engage the gears 53, 55, the shaft also carrying a clutch 62 moved by a lever 65. In operation, the rotation of the shaft 51 raises the machine, whilst the grinding-wheel is rotating and revolving in an orbital path, until the shaft 50 strikes the lever 65 and moves the clutch lever and clutch so that the lever is held by a roller 69 on a spring-pressed lever 68, the clutch engaging the gear 56. This causes rotation of the gear 55 at higher speed than the shaft 51, resulting in the descent of the shaft etc.; the switch 26 is so positioned that when the grinding- wheel reaches a desired position, a plate 49 carried by the shaft 50 opens the switch and stops the motor 30. The apparatus is positioned centrally in the cylinder by upper cores 71, 72 and lower cores 73, 74 tapered to enter the cylinder and having central openings to receive the shaft 15; the lower cores are lifted by cords 80 and retained in position by wedges 81. After clamping the base 5 and a cross bar 94 in position, the cores are removed by means of the cords.

The probe position may be determined by measuring markers along the draw line or by an electromagnetic signal transmitted from the probe to a portable receiver 40 carried by an operator at the ground surface and providing an audible warning of the proximity of the probe. The gas sensor (11) Fig. 3 (not shown) may be a Toguchi type connected in a bridge arrangement to compensate for variations in supply potential and providing from loud-speaker (52) a signal of frequency dependent upon gas concentration.

Title: Process of bleaching paper pulp
IPC: D21C9/14
Filed: 1965-02-11
Abstract: 1,091,124. Bleaching paper pulp. LA CELLULOSE DU PIN. Feb. 11, 1965 [Feb. 11, 1964], No. 6015/65. Headings D1L and D1P. Paper pulp is bleached by treating it with chlorine, and then with milk of lime, followed by chlorination in the presence of chlorine dioxide, a further treatment with milk of lime and treatment with chlorine dioxide. The process may be effected by introducing the crude pulp having a density of 3.5% by weight by pump 21 into mixer 22 in which chlorine is admitted through 22a, chlorination being carried out at 18‹-20‹C in tower 23 which the pulp takes about one hour to traverse, and the pulp being concentrated to a density of 15-20% by weight in screw press 24 prior to the addition of milk of lime introduced into mixer 25 through 25a which reduces the density to not less than 5% by weight and heating to 50‹C by means of steam through 25b or -means of the milk of lime or both. The pulp is then passed to filter 26 where it is washed with water, passed into mixer 27 where chlorine and 0.15-0.2% by weight of chlorine dioxide based on the weight of the dry pulp are added at 27a, chlorination being effected in tower 28 at ambient temperature prior to the addition of milk of lime through 28a changing the density from 5% to approximately 4% by weight and then passed by pulp 29 to liming tower 30 where it is heated by steam injected through 28b to about 35‹C for approximately 1 hour, its pH on leaving the tower 'being 9-10 and its density 4% by weight. It is then passed to filter 31 where it is washed and brought up to a density at 15% by weight, to mixer 33 by high density pump 32 where chlorine dioxide is added through 33a and steam introduced through 33b to raise the temperature of the pulp to 70‹C, and to chlorine dioxide tower 34 which it traverses in 4-5 hours, and is then treated with a solution of SO 2  to neutralise excess chlorine dioxide and washed over filter 35. The tower 28 in which chlorination in the presence of chlorine dioxide takes place may be dispensed with, contact for 2-3 minutes between the pulp and these reagents being sufficient.

Title: Process for preparing salts of quaternary ammonium monoazo dyes
IPC: C09B44/12
Filed: 1958-02-25
Abstract: The invention comprises hydrazines of formula: <FORM:0866087/IV (b)/1> in which the hydrazine group is attached to a 2- or 4-carbon atom of the pyridine ring, B is a benzene radical, Y is nitro and n is 1 or 2.  They are used in the preparation of azo dyes (see Group IV(c)) and are prepared by reacting a mono- or di-nitrophenylhydrazine with a 2- or 4-halo-pyridine.  Compounds specified are N1-4-nitrophenyl-N2-2- or -4-pyridyl-hydrazine and N1-2:4-dinitrophenyl-N2-2-or -4-pyridyl-hydrazine.  In Examples: (1) 4-nitrophenyl-hydrazine is heated in an excess of 2-bromopyridine to give 2-p-nitrophenyl-hydrazinyl-pyridine hydrobromide; (2) the product of (1) is converted to the base by heating with aqueous sodium bicarbonate.  Specification 793,587 is referred to.ALSO:Azo dyes of formula:-  <FORM:0866087/IV(c)/1> wherein A is the residue of a pyridine nucleus having the azo group in the 2- and 4-positions to the quaternized nitrogen, R is an organic radical, B is a benzene or naphthalene radical and X- is an anion are prepared by reacting a corresponding nitroarylhydrazine with a halopyridine (see Group IV(b)), oxidizing the resulting disubstituted hydrazine to an azo compound, reducing the nitro group to amino and quaternizing said azo compound.  The dyes give red shades on polyacrylonitrile fibres.  In examples 2- p-nitrophenylhydrazinylpyridine hydrobromide is prepared and oxidized to the azo compound by refluxing with sodium nitrite in glacial acetic acid or by passing air into a heated mixture thereof with aqueous sodium hydroxide. The nitro-azo compound is reduced with sodium sulphide to give the amino-azo compound which is quaternized with methyl iodide.  The use of 4-halopyridines and 2 : 4-dinitrophenylhydrazines as starting materials and of dimethyl sulphate, benzyl chloride and ethyl bromide as quaternizing agents is specified.  Specification 793,587 is referred to.

Abstract: 868,266. Patterns for moulding models of car bodywork &c. VERTIN, T. D. Feb. 25, 1959, No. 6571/59. Class 87(2). A model of an object, e.g. a car bonnet, is made from a new design draft by first construcing a wooden box 12 with its upper open face in plan and elevation corresponding to the perimeter of the object. Three female templates 23, 25, 26 having lower inked edges 24, 27, 28 of desired contour are then fixed on to walls 14, 17 above the box which is filled with wood and foamed plastic up to a point about an inch or less below said edges and wax 36 is built up on the foamed material around the templates so that the contoured edges are embedded therein. When the wax has set the templates are removed leaving inked grooves 37 in wax mounds 39 separated by valleys 38. The process is repeated using three transverse templates and inked grooves 46 are obtained along transverse mounds. The depressions 48 in the wax layer are then filled up using the grooves as reference points, and the resultant rough shape pared down to the level of the bottom of the grooves. Epoxy resin is then applied to the wax pattern surface to form a female mould which is used to mould male patterns of similar plastic material.
