Title: Honing apparatus
IPC: B24D15/06
Filed: 1975-04-07
Abstract: 1499975 Honing tools BG PARSONS 7 April 1975 [7 Jan 1974] 32472/73 Heading B3D Apparatus for honing plane irons, chisels and like woodworking tools comprises a jig 8 means for holding an oil-stone 13 with a longitudinally extensive, flat honing surface 14 and for adjusting the attitude of the honing surface with respect to the jig both longitudinally and laterally, and a carrier 9 movable with respect to the jig and adapted to hold an iron or chisel blade 23 at an appropriate honing angle, the jig including two tracks 16 extending longitudinally one each side of the honing surface and at least capable of being coplanar with the surface or of lying in a plane parallel thereto and the carrier straddling the surface and supported on runners 17 engageable with each track. The body of the jig is of inverted channel section and has an aperture 12 for receiving the stone 13 which is supported by adjustable bearers 24. Gauge strips 27 can be mounted by screws 28 on the jig so that the bearers can be adjusted by nuts 26 to engage the honing surface 14 with the strips, the stone then being secured in position by end clamping screws 31. Bars 15 are mounted on each side of the body to form the tracks 16. The bars are pivotally adjustable about screws 33 at one end of the body so as to be parallel or slightly inclined to the tracks, the other end of the bars being secured to the body by screws 35 passing through oversize or elongated holes in the bars. Between the bars are strips 36 having projections 37 which act as stops for the carrier. The runners 17 have rollers or grooves engaging the tracks and are formed with bell-mouthed recesses 20 receiving trunnions 18, 19. A spindle 40 is screw threaded into the trunnion 18 and has a plain portion 41 on which a jaw 22 is rotatably mounted. The trunnion 19 is screw threaded on to the spindle and carries a jaw 21, rotation of the trunnion moving the jaws together to grip an iron or chisel to be sharpened against locating surfaces 45, secondary inclined surfaces 46, 47, one 42 of which is convex, acting to urge the iron or chisel against the locating surfaces. Further surfaces 48, 49, 50 are provided on the opposite side of the spindle 40. Auxiliary locating surfaces 51 are provided for use with mortice type chisels and plough irons. Graduations 54 are provided for use in determining the extent of projection of the chisel or iron from the jaws for a particular honing angle. In use, the chisel or iron is clamped in position between the jaws and the carrier reciprocated along the tracks with the chisel or iron engaging the stone and the tracks parallel to the surface. A curved profile may be given to a plane iron after the main honing operation by inclining first one and then the other of the tracks for a few honing strokes.

Patent GB-875163-A (GB)
Title: Dyeing process
Inventor: COLLINS JAMES KENWORTHY
IPC: D06P3/84
Filed: 1959-09-28
Abstract: In the dyeing of textile materials comprising mixtures of protein and cellulose fibres with cold-dyeing reactive dyes at temperatures not exceeding 30 DEG C., the uptake of dye by the protein fibres is controlled by effecting the dyeing in the presence of a colourless, water-soluble organic compound containing an anionic solubilizing group.  Suitable compounds, which may be applied to the textile before or during dyeing, are salts of naphthalene sulphonic acids, of alkylated benzene sulphonic acids, of alkylated naphthalene sulphonic acids, of condensation products of formaldehyde with naphthalene sulphonic acids, of sulphurized phenols, or of sulphonated or sulphated oils, fats or fatty alcohols.  Dyeing may also be effected in the presence of acidbinding agents and neutral inorganic salts. When the dyed protein fibre is paler in shade than the dyed cellulose fibre, a second dyeing with a non-reactive dye having an affinity for the protein fibre may be applied.  The process is applicable to textiles comprising mixtures of natural or regenerated cellulose fibres with natural or regenerated protein fibres. Suitable cold-dyeing reactive dyes are described in Specifications 209,723, 774,925 and 785,222.  Examples are given.

Abstract: 1,196,436. Light deflectors. HUGHES AIRCRAFT CO. 18 July, 1967 [26 Sept., 1966], No. 33031/67. Heading H4F. In a light beam deflector utilizing a plurality of electro-optic prisms each having a fielddependent refractive index arranged adjacent to each other as shown in Fig. 1, an input beam 20, Fig. 2, is focused on to end 36 of the plurality of electro-optic prisms 28 wherein it is deflected, and by means of mirror 32 the beam is reflected back through the prisms to be further deflected, the total deflection being equal to the sum of the deflections. The prisms may comprise KDP crystalline material, the electric field being applied in the direction of the C axes. The prisms may be arranged with the C axes alternately directed into and out of the plane of Fig. 1, or they may be uniformly directed in which case each prism is provided with an independent field. Optical system 22, 24 compresses the beam in the direction perpendicular to the plane in which the light beam is deflected and optical system 44, 46 expands the beam in its compressed dimension so that the output beam 48 is the same size as the input beam 20. To increase the deflection the beam may be reflected back and forth through the electrooptic prisms a plurality of times, Fig. 3 (not shown). In a further arrangement the ordinary ray of the input beam is passed by a Gran- Thompson prism (82, Fig. 4, not shown) via an optical reduction system (86, 88) and a 45 degrees polarization rotator (90) to the electrooptic prisms. The reflected beam is passed back through the system, is re-sized by lenses (86, 88), and the resulting extraordinary ray is reflected by the Gran-Thompson prism to a display screen. Reference has been directed by the Comptroller to Specifications 1,015,376 and 1,060,954.

[A Specification was laid open to inspection under Sect. 91 of the Acts, June 15, 1936.] [Class 7 (ii)] An exhaust-silencer for internal-combustion engines comprises a casing 1, Fig. 1, in which is a central passage formed by a tube 2 which is interrupted by two or more groups of sounddamping chambers 5 surrounding the passage, the groups being connected by a section 2<11>, or sections, of the tube 2, and the walls of the chambers, which are perforated, confining sound-absorbing material which is out of the main path.of the exhaust gases, and the groups being of equal length and the material such as to absorb the higher frequencies, such as 850 to 10,000 Hz, while the lower frequencies which are not thus included are damped by the enlargements in the cross-section of the passage for the gases formed by the groups of chambers. Each group consists of a number of units each comprising an annular sieve 9 filled with glass wool 4. Each sieve is mounted in a sheet-metal holder 6 having circular flanges ; distance members are arranged alternately with the units. A gap 8 in the side of each holder 6 and a circular hole 12 in each distance member provide access of sound to the material 4.

Title: Manufacture of 1-alkoxy and 1-substituted-alkoxy-2-acylaminobenzene-arsonic acids
IPC: C07F9/74
Filed: 1931-11-30
Abstract: 1-Alkoxy- or 1-substituted alkoxy-2-acylaminobenzene-arsonic acids are prepared by introducing an aliphatic residue into the hydroxy group of a 2-acylamino-1-phenol containing a nitro group, reducing the product, and finally replacing the amino group by the arsonic acid residue in known manner.
