Title: Improvements in and relating to surface grinding machines
IPC: B24B47/06
Filed: 1941-08-27
Abstract: 549,657. Hydraulic machines. NORTON CO Aug. 27, 1941, No. 10947. Convention date, Oct. 18, 1940. [Class 69 (ii)] [Also in Group XXIII] In apparatus comprising a slide carrying a grinding-wheel or a work-support and having traversing-means comprising a piston and cylinder, a metering-device is provided for controlling the amount of fluid exhausted from the cylinder, and thereby limiting the traverse to a predetermined distance. The apparatus shown in the Figure comprises, as described in Specification 422,160, a grinding-wheel slide 13 and a worktable 11 traversed by pistons 66, 22 mounted in cylinders 65, 21 to which liquid from a pump 27 is supplied through manually or automatically operated reversing-valves 69, 31. The cylinder 65 is supplied through a pipe 95, a throttlevalve 96, pipes 97, 70, and the valve 69, and exhausts through pipes 108, 109, a piston-valve 110, and a pipe 111 into the chamber 112 of a metering-device 113. When the valve 31 is operated, the throw-over lever 55 thereof depresses momentarily the stem 126 of a pistonvalve 125, the pipe 95 is placed in communication with a pipe 131, the valve 110 is operated, the cylinder 65 is permitted to exhaust into the metering chamber 112, and the slide 13 is traversed. The traverse is determined by adjusting a stop 116 for the piston 114 of the metering device. When the valve-stem 126 returns, the pipe 131 communicates through a pipe 134 with a pipe 40, the valve 110 returns, and the metering-chamber is exhausted through pipes 111, 121, 122, 40. An adjustable throttle-valve 150 in the pipe 134 serves to prevent return of the valve 110 until the chamber 112 has been filled. For rendering the metering-device inoperative during wheel-trueing, the hydraulic circuit includes a manually-operated piston-valve 140. On movement of this valve into the lefthand position, the pipe 95 communicates with a pipe 146, the valve 125 is maintained depressed and consequently the valve 110 is maintained in operated position. Thereafter, pipe 109 is connected through pipes 111, 148 with exhaust pipe 40, and the metering-chamber 112 is also connected to the pipe 40 to render inoperative the metering-valve. The valve 96 can be adjusted by a knob 98 to stop or to control the speed of the slide 13. During wheel-trueing, a slow continuous traverse is imparted to the slide by so adjusting the valve that a regulated flow through a port 99 occurs. Specification 6043/14, [Class 60], also is referred to.

Abstract: 1,180,344. Valves; hydrostatic transmission. SPERRY RAND CORP. 7 March, 1968 [8 March, 1967], No. 11085/68. Headings F2C, F2D and F2V. A pressure surge control valve for the hydrostatic transmissions of small land vehicles comprises a valve member 81 controlling the communication between an inlet 64 and an outlet 72 and having a hollow cylindrical body portion 82 in which slides a spring-loaded piston 87 to form a chamber 83 connected to the inlet via a restricted passage 84 in the conical nose of the valve member. Pressure increase in the inlet causes an increase in pressure in the chamber 83 to move the piston downwards but due to the restricted passage 84 a pressure differential is formed across the valve member which opens the valve to connect the inlet to the outlet until the differential decreases sufficiently. A pin 85 slidable in the passage 84 acts as a self-cleaning means. In use the valve 15 is connected via check valves 67, 68 and in parallel with an adjustable high-pressure relief valve 70 to the high- and low-pressure lines 12, 13 between a variable displacement swashplate pump 11 and a swashplate motor 14 which lines are also connected by a by-pass valve 74. A make-up gear pump 54 is connected via check valves 57, 58 with the pressure lines 12, 13 and is provided with a pressure relief valve 61 communicating with the reservoir 36.

Abstract: 331,597. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). April 10, 1929. #-Naphthylaminophenoxy fatty acids are obtained by treating a #-naphthol or #-naphthylamine or a substitution product of either, with a sulphite and a 3- or 4-aminophenoxy fatty acid or derivative thereof. As derivatives of the naphthols and naphthylamines are used, the carhoxylic acids, mono- and polysulphonic acids, dioxysulphonic acids, aminooxysulphonic acids, and diaminonaphthalenes or sulphonic acids thereof, and as derivatives of the aminoaryl phenoxyacetic acids, the esters, the aminocresoxy compounds, or the aminoaryl-#-propionic acids. In examples, (1) 2-naphthol-3-carboxylic acid reacts with sodium-4-aminophenoxyacetate and sulphite; the 2<1>-naphthyl-4-aminophenoxy acetic acid obtained couples with diazotized 4-nitraniline-2-sulphonic acid in acetic acid to give a blue dye; 6<1>-carboxy-2<1>-naphthyl-4-aminophenoxyacetic acid is obtained by a similar process and gives a blue-violet dye with the above component, and a coloured nitroso compound; the same end products are obtained when the naphthylaminocarboxylic acids are used; (2) sodium-2-naphthol-7-sulphonate reacts with sodium 4-aminophenoxyacetate and sulphite; the product gives a violet dye with the above component and a yellowish nitroso compound; a similar reaction takes place with 2-naphthol-5 : 7- disulphonic acid, or -5-, 6-. or 8-monosulphonic acid, or with 2-naphthylamine-5: 7-disulphonic acid, or -5-, 6-, 7-, or 8-monosulphonic acids; (3) sodium-2.: 8-aminonaphthol-6-sulphonic acid reacts with sodium 4-aminophenoxyacetate and sulphite ; the same product is obtained with the use of 2 : 8-dioxynaphthalene-6-sulphonic acid; the 1 : 6-aminonaphthal-3-sulphonic acid reacts similarly to give a product which gives a yellow nitroso-diazo compound and couples with the above-mentioned component to give a blue-violet dye; (4) sodium 2: 5-dioxynaphthalene-7-sulphonate reacts with the aminophenoxv acetate and sulphite to give a product which couples with the above diazo component to give a blueviolet dye. and gives a nitroso compound: the 4- aminophenoxyacetic acid ethyl ester may be employed and afterwards saponified, and may be replaced by the 4-amino-2-methylphenoxyacetic acid, the 4-amino-2-chlorphenoxyacetic acid, the 4-aminophenoxy-#-propionic acid, and the 3- aminophenoxyacetic acid, to give products, all of which possess similar properties to those obtained irom the 4-aminophenoxyacetic acid; (5) sodium 2 : 6-diaminonaphthalene - 8 - sulphonate reacts with sodium 4-aminophenoxyacetate and sulphite to give a similar product. 3- or 4-Aminophenoxy fatty acids are obtained by the interaction of the sodium salts of the corresponding nitrophenols with monochloracetic acid or #-chloropropionic acid, and subsequent reduction, and the analogous aminocresoxy and aminochlorophenoxy compounds are obtained in a similar way.
