IPC: A23G7/00
Filed: 1925-05-02
Abstract: 255,959. Forgrove Machinery Co., Ltd., and Grover, F. May 2, 1925. Steam-cutting machines.-In an apparatus for dividing plastic material into tablets of a uniform size. a reciprocating multiple blade holder is provided having equidistant blades which project progressively to different depths, the cutting being performed progressively deeper, until the end tablet is severed, as the strip of material advances through the machine. Alternatively this effect may be attained by suitably adjusting the angle of the bar. The apparatus is especially applicable to the division of sweetmeats, for instance caramels. A rope of material is fed between rollers 2, 2a on to an endless travelling belt 3 which advances it beneath a knife bar 8 provided with a series of blades 9, each succeeding blade, from the feed end, depending a progressive amount. The bar is reciprocated vertically by cranks 11 on shafts 12, 12<a>, the cranks being connected to the bar by links 10. The bar 8 is given a horizontal movement to feed the material or to follow its forward movement by a cam 16 acting on a rocking spring-controlled lever 18 connected to the bar by a link 19. At the end of a forward movement the bar 8 is raised, returned to its previous position and lowered again so that the blades enter divisions already partly cut and deepen the incision. An endless chain 5 arranged parallel to and above the belt 3 has a series of laterally projecting fingers which project between the blades 9 and hold the material down as the blades are withdrawn. The belt 3 is supported against the cutting pressure by a surface 20 mounted on rollers 21 and given a to-and-fro movement by links 22 connected to the lever 18. The feed of the material may be continuous or, as shown, intermittent. The shafts 12, 12a are rotated continuously while a step-by-step motion is given to the belt 3, chain 5 and the feed rollers 2, 2<a> through gearing driven and controlled by a Geneva stop device 23, which is actuated by an arm 24 on the shaft 12<a>.

Filed: 1921-04-21
Abstract: 166,510. Akt.-Ges. Brown, Boveri, et Cie. July 17, 1920, [Convention date]. Thrust bearings.-In a pivoted-block thrust bearing, the ends of each bearing block d are formed as mutually-inclined planes which coact with bodies having convex supporting surfaces, in order to secure a uniform distribution of load. In the form shown in Fig. 1, slide shoes u support the ends of the blocks by spherical surfaces. In the form shown in Fig. 3, slide shoes are replaced by balls g. By making the angles a, # of different magnitudes, an unsymmetrical loading of the block is effected which facilitates the forming of the usual wedge of oil. Pairs of balls may be used between adjacent blocks in place of single balls. In the form shown in Fig. 6, the blocks d are supported symmetrically with respect to the pressure resultant P of the oil film, but unsymmetrically with respect to the centre z of the bearing surface. Such arrangement facilitates the wedge formation of the oil film.

Title: Improvements in fluorescent textiles
IPC: D06L3/12
Filed: 1946-04-16
Abstract: Fluorescent textiles are made by dyeing a cellulose ester fabric with a dilute solution of a daylight fluorescent dye and/or a colourless substance which is fluorescent in ultraviolet light, in a strong aqueous solution of a solvent for the dye, which solvent is also a swelling agent for the cellulose ester, the dyeing being carried out for such time and at such a temperature that the dye is dispersed in a solvated state in the filaments while the filaments approach but do not exceed a state of incipient coalescence, the amount of dye dispersed in the fabric being not more than 0.025 grams of yellow-green fluorescent dye or 0.015 grams of red fluorescent dye per cubic centimetre of fabric filament, and preferably not more than 0.0005 grams per square centimetre of fabric.  The fabric may be tinted with normal dyes before or after dyeing with fluorescent dyes according to the invention, but the amount of such dye must be insufficient to quench the emission of light by the fluorescent dye. In examples, cellulose acetate fabric is dyed (1) with meta-diethylamino-phenolphthalein hydrochloride in 50 per cent aqueous ethyl alcohol at 27 DEG  C.; (2) with imino-di-(p-dimethylaminophenyl)-methane hydrochloride in 35 per cent aqueous isopropyl alcohol at 50 DEG  C.; (3) with meta-methylethylamino-phenolphthalein hydrochloride in an aqueous bath containing 10 per cent of ethylene glycol monomethylether and 15 per cent of methyl alcohol at 18 DEG  C.; (4) with meta-monobutylamino-phenolphthalein hydrochloride in 40 per cent aqueous ethyl alcohol at 20 DEG  C.; (5) with Fluorescent Yellow HEB from an aqueous bath, rinsed and then shaded with meta - monoethylamino - phenolphthalein ethyl ester hydrochloride and metadiethylamino - phenolphthalein hydrochloride from an aqueous bath containing 15 per cent of formic acid at 180 DEG  F.; (6) with the first bath of (5), rinsed and shaded with a specified triphenylmethane type dyestuff from a 15 per cent aqueous formic acid solution at 180 DEG  C.; (7) with a specified coumarone type dyestuff from a 50 per cent aqueous alcohol bath at 27 DEG  C., rinsed and shaded with Pontacyl Brillinat Blue RR from an aqueous bath containing 35 per cent of formic acid; (8) with the first bath of (1) used at reduced strength and then with the first bath of (7); and (8) commercially tinted cellulose acetate fabric is dyed with the first bath of (7) or the first bath of (8).

Title: Improvements in or relating to the supply of liquid fuel to the cylinder injection valves of internal combustion engines
IPC: F02D1/00
Filed: 1926-05-04
Abstract: 267,746. Braren, L. K. May 4, 1926. Cylinders receiving liquid fuel. - Liquid fuel, or a mixture thereof with air or other gas produced and supplied by a pump under high pressure to a chamber 1 and under a lower pressure to a chamber 2 as described in Specification 268,846, is directed first from the high-pressure and then from the low-pressure chamber to the cylinder injection valves by a piston valve 5, Fig. 1, or a rotary valve 71, Fig. 5, the highpressure mixture passing through the injection valve into the cylinder, and the low-pressure mixture serving to reduce the pressure under the injection valve to facilitate its closing. The mixture is distributed to pipe lines 23 leading to the various cylinders by a piston valve 20, Fig. 1, or by the rotary valve 71. The valve 5 is actuated by a lever 8 and a cam 7 having as many recesses as there are cylinders to be supplied, so that as the valve falls when the lever enters a recess, the mixture is supplied from the chamber 1 by passage 12, recess 10, and passage 16 to the distributing-valve 20, and as the valve is raised again, the supply from the chamber 1 is cut off and the chamber 2 opened by way of passage 14. groove 15 in valve, and passages 13, 10, 16. The valve 20 is formed with grooves 21 which connect the passage 16 in turn with the pipes 23, the valve being raised in stages by a stepped cam 24 and lever 25. The duration of the injection is varied by making the cam 7 tapering and moving the shaft 28 of the lever 8 axially by rack-and-pinion gearing. The timing of the injection is also varied by angular adjustment of the cam 8 by means of a sleeve 47, which carries pins 46 engaging spiral grooves 45 in an extension of the cam, and is adjusted by a nut 49. The pressures in the chambers 1 and 2 are maintained in a fixed ratio by an automatic differential piston valve arranged between the chambers, and excess pressure is blown off through a relief valve leading back to the fuel tank. The rotary form of valve 71, Figs. 5 and 8, has its interior divided into high and low pressure chambers 81, 82 by a partition 80, which also receives the differential piston valve 111, 112 and relief valve 131. The mixture is supplied to the chamber 81 from the pump through ports 84 and a port (not shown) in the valvo 71. As the valve 71 rotates, a port 88 therein connects the chamber 80 successively to the cylinder connections 87, after which the chamber 81 is connected thereto through recesses. 91, ports 90, and recesses 89. The duration of the injection is varied by making the port 88 and recesses 91 with inclined edges, and by axial adjustment of the, valve 71 by means of rack- and-pinion gear 76. 77.

Patent GB-751045-A (GB)
Title: Improvements in the production of low density metal powders
IPC: B22F9/30
Filed: 1954-04-23
Abstract: Low density metal powder, e.g. having a bulk density of less than 0,9 Kg per litre, is produced by the thermal decomposition of metal carbonyls in the free space of a heated vessel by keeping the temperature of the wall of the vessel, particularly at the point of entry of the carbonyl, at least 270 DEG C. higher than the temperature at the middle of the free space.  The temperature difference may be achieved by (a) increasing the rate of carbonyl feed, (b) increasing the supply of heat to the walls or (c) the supply of cold gases or vapours.  To produce very low density powders, the temperature at the middle of the free space is kept below 300 DEG C., e.g. at 230 DEG C., by supplying carbonyl to the decomposition chamber in such an amount that the effluent carbon monoxide contains undecomposed carbonyl which has, however, a partial pressure considerably below the saturation pressure of the carbonyl at room temperature.  An example of the production of Ni powder is given.  Ni powder and Fe-Ni powder produced by the process may be used for the manufacture of electrode frameworks, for alkaline accumulators and for porous plates and tubes. Specification 679,439 is referred to.
