Title: Improvements relating to the mounting of rotors of rotary machines
IPC: F01D5/06
Filed: 1950-12-11
Abstract: 682,831. Securing rotor wheels to shafts. GENERAL MOTORS CORPORATION. Dec. 11, 1950 [Jan. 5, 1950], No. 30190/50. Class 80 (ii). The rotor wheels of an elastic fluid turbine or compressor, or the like, are splined to a shaft and centred thereon by the innermost. faces of the wheel splines engaging an unsplined portion of the shaft. As shown, the hubs 34, 36 of a pair of adjacent rotor wheels have internal splines 23 which engage with splines 14 on a shaft 10. The internal diameter of the splines 28 on the wheel hubs is equal to the diameter of unsplined portions 16 of the shaft 10, these parts being machined to fit each other. The splineways between the splines 28, 14, on the wheels and shaft respectively, are of such a depth that the splines interengage only on a part of their flanks and not on their lands, viz. not on their innermost and outermost portions, respectively. Tho sole radial contact points between the hubs and the shaft are therefore those of the lands of the hub splines 28 upon the unsplined portions 16 of the shaft. The wheels are held in place by a threaded clamping collar 54.

Title: Paper or non-woven fabric of regenerated cellulose fibres and method for producing the same
IPC: D04H1/54
Filed: 1972-06-28
Abstract: 1394085 Paper; non-woven fabric MITSUBISHI RAYON CO Ltd 28 June 1972 30219/ 72 Heading D2B A method of making a paper or non-woven fabric comprising regenerated cellulose fibres comprises (a) dispersing spun and stretched fibres comprising hydroxy methyl cellulose xanthate in an aqueous medium having a pH lower than 6.0 at a temperature lower than 30C; (b) forming the fibres into a web by a wet-forming method; (c) dehydrating the web to an extent that the "process moisture percentage" of the web is lower than 700%, the fibres after dehydration being characterised by (1) a γ-value greater than 30, (2) a "decomposition degree" less than 75%, and (3) a "process swelling degree" less than 250%; (d) subjecting at least a portion of the surface of the dehydrated web to a pressure greater than 2 Kg/cm at 90-180C, thereby fusing and decomposing the hydroxymethyl cellulose xanthate in the pressed portion and simultaneously bonding the fibres in said portion to each other, and (e) subjecting the pressed web to a regeneration treatment to decompose remaining hydroxymethyl cellulose xanthate into cellulose. The aqueous medium in which the hydroxymethyl cellulose xanthate fibres is dispersed may contain dispersing agents such as polyethylene oxide, carboxymethyl cellulose, sodium polyacrylate, polyacrylamide, and various latexes. The surface of the dehydrated web may be fused over an area from 5 to 40% of the total surface area of the web. Embossing rolls or smooth rolls in association with a plastics net may be used for this purpose, (Figs. 4, 5 not shown). The fused areas may form a spotted pattern and small holes may be formed in such areas. Use of a roll at high temperature but relatively low pressure produces a web having one side fused and transparent. The hydroxymethyl cellulose xanthate fibres may be blended with fibres which do not fuse at 90-180C e.g. pulp, rayon, acrylic, polyester, polyamide, and acetate fibres. Regeneration may be carried out with an aqueous acidic solution at a temperature higher than 50C. The fibrous parts of the pressed web may be subjected to shrinkage or crimping during regeneration by a two-stage aqueous acid treatment. The product may weigh from 10- 200 g. per square meter and may be used in the manufacture of tampons, pads, sheets, table cloths, diapers, curtains inter alia.

Title: Improvements in hydraulic brakes for motor vehicles
IPC: B60T11/28
Filed: 1939-11-20
Abstract: 535,237. Hydraulic brakes for vehicles. AKTIEBOLAGET VOLVO. Nov. 20, 1939, No. 30444. Convention date, Nov. 7. [Class 103 (i)] Hydraulic brakes for motor vehicles, in which liquid is forced from a main cylinder into a wheel cylinder, are constructed to have release of liquid pressure in the wheel cylinder effected first at a rapid rate and then more slowly, the main cylinder communicating with the wheel cylinder through a large opening, controlled by a valve self-closing at a certain releasing pressure, and also through a narrow opening in parallel with the large opening. In the construction shown, liquid put under pressure by the return spring of the brake shoes is forced through the pipe 5 to lift the valve cap 18 so that the liquid passes readily into the main cylinder 1 through apertures in the flange 21 of the valve 18; when the pressure is sufficiently reduced the valve 18 is forced down by the spring 16 to close the apertures in the flange 18 and the liquid is then discharged more slowly through a small aperture 25 in the valve 18. When the brake is applied liquid is forced through holes 20 in the sides of the valve and presses aside the rubber body 19 in the valve 18 and passes it through the opening 17 into the pipe 5.

Title: Serial printing device

Filed: 1974-07-10
Abstract: 1471366 Selective printing ING C OLIVETTI & C SpA 10 July 1974 [14 Aug 1973] 30595/74 Heading B6F A serial printer includes a drum 12 carrying type elements 30 (each with two type characters 34) which are movable radially outwards against the action of rings 33. The drum 12 is rotatably held by support 40, the latter being pivoted about pin 61. A rocker 82 is pivotally attached to first lever 87 at one end, at an intermediate point to the support 40 and at the other end to a hammer 95, aligned to impact a type element in the print position against the platen 10. Impression is caused by energizing electromagnet 116 which attracts armature 115. This causes arm 120 to move support 40 to the right (as viewed). As a result rocker 82 turns clockwise about pin 81 and by virture of the system's geometry causes hammer 95 to strike the selected element 30 and move it radially outwards relative to the other elements 30. All the above are mounted on a moving type carriage. As shown drum 12 is rotated from a motor (not shown) via gears 43, 45 and universal joint 42; movement of the drum 12 is sensed photoelectrically 56. The lower of the two characters 34 is selected by energizing electromagnet 70 to attract armature 69. Impression adjustment is achieved by nut 78 controlling spring 74 which restores the drum 12 from the impression position. Drum 12 is removable by displacement of hammer 95, arm 92 and nut 46.

The compound is then coupled with a diazonium compound in the 4-position and then reduced to leave a diazonium group in the 4-position or by introduction of a nitro group in the 4-position followed by reduction and diazotization. (4) wherein R is alkyl- or aryl-mercapto.-1,5- dichloro-2-nitro-benzene is reacted as in method (1) or (2) to obtain a -NR 3 R 4  group in the 1-position and a -NR 1 R 2  group in the 2- position. The compound is now nitrated to form a 4-nitro group and then the 5-chloro radical is replaced by an alkyl- or aryl-mercapto group. The 4-nitro group is then reduced and diazotized to produce the diazonium compound.
