Title: Improvements in means for automatically controlling the fuel supply valves of steam boilers
IPC: F22B37/46
Filed: 1928-11-27
Abstract: 324,170. Michael, N. F., and Young, A. J. Nov. 27, 1928. Valves controlled by pilot or relay valves. -A valve device, for controlling the supply of liquid fuel to steam generators and adapted to close in the event of the mater level falling unduly or the feed supply failing, is normally held in the open position by a pivoted catch actuated by a pair of pistons, one subject to the pressure in the feed pipe and the other to feed-pipe pressure under the control of a float-actuated auxiliarv valve. The main valve MM is loaded by spring P arranged between a bridge Q supported by pillars from the casing cover and an abutment O on the valve spindle N. The abutment O has a projection D adapted to be engaged by a catch 45 pivoted to the beforementioned pillars and coupled by a link V to a crosshead W on the actuating spindle X. The spindle X is loaded by a spring AC and is fitted with pistons AE and Y working in cylinders AD and Z carried by a tubular support AR attached to the valve casing LL. The piston Y which is the smaller of the two, is acted on by the pressure in the feed pipe. The cylinder AD is fitted with a bleed port AS and is connected by a pipe AO with an auxiliary valve casing K. The auxiliary valve casing is formed on the end cover of a.float chamber A and contains a seat J for the auxiliarv valve G. The valve G is connected by a link F with the float arm E of a pivoted float D working in the chamber A. The chamber A is connected by a pipe AG to the boiler above the water level and by the pipe AH, which is restricted by a plug AN, to the boiler below the water level. In the event of the water level falling, the float drops to open the auxiliary valve whereby feed pipe pressure admitted by a pipe AK passes by way of pipe AO to the cylinder AD, depressing the piston AE to release the catch and allow the main valve to close.

Abstract: 1,207,300. Worm and rack gearing; bearings. WEBKZEUGMASCHINTENFABRIK ADOLF WALDRICH COBURG. 14 July, 1969 [12 July, 1968], No. 35383/69. Headings F2A and F2Q. In a hydrostatic bearing arrangement between interengaging tooth flanks of a worm 1 and rack 7, oil grooves 8 in the rack tooth flanks 5 facing in one direction receive high pressure oil from a different supply from the grooves 9 in the rack tooth flanks 6 facing in the other direction, the supply being via distributer bars 15, 16 which slidably engage side faces 12 of the rack 7 and are guided in a stationary housing 18, the bars 15, 16 being urged against the faces 12 by the oil supply pressure and by springs 28. The cup springs 28 act on pistons 20 in the housing 19, the pistons bearing on the distributer bars 15 or 16. Oil pressure in galleries 23, 24 of the housing also urges the pistons 20 against the bars 15, 16. Bores 25, 26 in the pistons 20 and bars 15, 16 connect the galleries 23, 24 to grooves 17 in the bars 15, 16, lines 10, 11 from the flank grooves 8, 9 being covered by the grooves 17 of respective distributer bars 15, 16. The grooves 8, 9 are initially filled during relative movement of the worm and rack, by filler holes 32, 33 at the ends of the distributer bars, connected to a low pressure supply. These holes may be in the bars (as at 32) or in separate transverse bars 34 (as at 33). A wedge 29 allows adjustment of the housing 19 relative to the rack 7. In Fig. 3 (not shown), the pistons are omitted, the springs and oil pressure acting directly on the backs of the distributer bars.
Patent GB-620855-A (GB)
Title: Improvements in the manufacture of bromine-containing compounds
IPC: C07C17/275
Filed: 1946-11-29
Abstract: Bromine-containing compounds are obtained by reacting an olefine compound, in which, if present in a carbocyclic structure, the double bond is not conjugated with any other double bond within the carboxylic structure, with a bromomethane containing at least three halogen atoms, either by irradiating with actinic light, or by heating in the presence of a diacyl peroxide at its decomposition temperature.  Preferred bromomethanes are carbon tetrabromide and bromoform, but other members of the class which may be used are CBr2ClH, CBrCl2H, CBr3Cl, CBr2Cl2, CBrCl3, CBr2F2, CBrF3, CBr3F.  The olefinic compound may be represented as <FORM:0620855/IV (b)/1> where R1, R2, R3, and R4 are either hydrogen, alkyl, polymethylene, aryl, substituted alkyl, or halogen radicals, where any two R's may be linked to form a non-aromatic ring.  Specified compounds are cyclohexene, butene-2, oleic acid and esters, propene, butene-1, isobutylene, vinylcyclohexane, a -methylstyrene, methallyl acetate, allyl chloride, vinyl acetic acid, and allyl ethyl ether.  It is preferred to have both R1 and R2 hydrogen.  A solvent may be used, e.g. benzene or carbon tetrachloride, and it is desirable to do so when the reaction is catalysed by the thermal decomposition of a peroxide, e.g. acetyl peroxide.  In examples 1-6, carbon tetrabromide is reacted with the following unsaturated compounds by heating at Ca. 70 DEG  whilst irradiating with actinic light: n-octene-1, ethylene, styrene, isobutylene, allyl acetate and undecylenic acid.  In examples 1 and 7, bromoform is reacted with n-octene-1 by heating at 80 DEG  C. in presence of acetyl peroxide.

Title: Process for the continuous separation of gas mixtures by means of gas chromatography
IPC: G01N30/58
Filed: 1957-11-13
Abstract: <PICT:0810767/III/1> In the separation of mixtures of gases with an absorbent by the chromatographic method, the absorbent is moved in countercurrent with the initial gas mixture.  Preferably the absorbent moves at a speed intermediate the speeds of the gases to be separated, or groups of gases, whereby one separated component passes to the top of the column and the other to the bottom.  In a suitable apparatus, the absorbent moves downwards through a column 2, and is fed upwards through a bridge pipe 6, container 7 and pipe 8 to a supply container 9 at the top of the column.  Hydrogen gas fed into a pipe 1 sweeps out all contaminants, and then, for example, a mixture of propylene and butylene is admitted at a pipe 5 and hydrogen through pipe 4. Hydrogen and the faster-moving propylene flow to the top of the column to a pipe 10, and the slower moving butylene and some hydrogen is carried downwards by the moving absorbent to pipe 3. The speed of the components may be increased or decreased by adjusting the movement of the absorbent, by increasing the diameter of the column or by heating it.  The process may be applied to multi-component gas mixtures, the two mixtures of simpler character produced in the first stage separation, being then further treated in a second stage separation.  Active carbon, silica gel and aluminium oxide are referred to as absorbents.

Title: Improvements in processes for the production of chemical conversion coatings upon aluminium and its alloys
IPC: C23C22/37
Filed: 1960-10-17
Abstract: In a process for the production of chemical conversion coatings on aluminium surfaces by treatment with an aqueous acid solution containing hexavalent chromium and a fluorine compound, the solution is replenished by the addition together of hexavalent chromium and one or more of hydrofluoric acid and alkali metal and ammonium fluorides in a ratio of 0,4 to 2 parts by weight of fluoride ion for each part by weight of hexavalent chromium (as CrO3).  When the coating solution also contains ferricyanide replenishment of this constituent is effected by the addition of at least 0,05 and preferably 0,2 to 1,0 parts by weight of ferricyanide or ferrocyanide per part of hexavalent chromium. When the fluoride is added exclusively as the alkali metal or ammonium fluoride the weight ratio of fluoride ion to hexavalent chromium is from 0,75 to 1,25 and when added as hydrofluoric acid the ratio should not exceed 0,8 and is preferably 0,5 to 0,75.  The pH of the coating solution should preferably be from 1,5 to 1,7 and is controlled by adjusting the proportion of chromic acid and/or hydrofluoric acid to the salts of these acids which are used for replenishment.  Any further control is made by adding nitric acid.  Examples of coating solutions are given, one consisting of chromic acid, sodium fluohorate, potassium fluozirconate, potassium ferricyanide, and water and the other consisting of chromic acid, potassium ferricyanide, hydrofluoric acid and water.  Specifications 735,819, 747,957 and U.S.A. Specifications 2,276,353, 2,507,956 and 2,796,371 are referred to.

[Class 80 (iii)] [Also in Group XIX] Relates to trip mechanism for gearing and particularly that of date indicators and dateindicating 'clocks. As applied to the months dial of a date-indicating clock, a wheel 2 with 24 teeth is attached to the months dial 1, a second wheel 3 with 12 teeth being secured to wheel 2 to act, in conjunction with a spring 6, as a device to prevent backlash. The driving member, consisting of a one-tooth wheel 7 is mounted on a sleeve 8, Fig. 3, rotatable on a spindle 11, driven from the clock, and to which are secured a 31-tooth wheel 9, and a snail 10. A pin 13 on the one-tooth wheel 7 engages, with lost motion, a slot 14 in the snail. A pin 15 on a spring-loaded lever 16, rests on the snail. When lever 16 is tripped by the snail, it strikes pin 13, rotates wheel 7, and the one tooth rapidly engages and disengages from the wheel 2, moving it through a distance of two teeth, the wheel 2 then being locked by the blank portion of the one-tooth wheel. In a modification, Fig. 4, the driving wheel is a disc 19 having two laterally-projecting teeth 20 and a cut-out recess 21 between them. The wheel 22 has each alternate tooth cut away for half the width of the wheel on its rear face. Specification 467,829, [Group XIX], is referred to.

Title: Improvements in and relating to base exchange water softening apparatus
IPC: C02F1/42
Filed: 1928-12-03
Abstract: 325,886. Olsson, O. Dec. 3, 1928. Purifying liquids.-A valve for a base exchange water softening apparatus consists of a. spring-pressed slide 2, Fig. 5, operating against a flat face of a valve casing 1. At certain determined angles of rotation of the valve various ports and passages in the valve are brought into suitable position with regard to other passages in the casing, so that the steps in the base exchange method may be effected while giving a constant water supply. Fig. 1 shows the filtering position. Water flows by a passage 4 and opening 5 in the valve to a channel 6 and pipe 7 to the filter returning by a pipe 8 and channels 9, 10 to the supply main 11. The return flow position, Fig. 2, is obtained bv a 90‹ clockwise rotation of the valve. Water enters by. the inlet 4 and opening 14 in the valve to channel 9 and pipe 8 passing upwards through filter, and returning by pipe 7, channels 6, 13 to exhaust 15. Simultaneously, unfiltered water passes by channel 12 to water main 11. The position wherein salt is added to the filter is shown in Fig. 3. Unfiltered water passes to the main 11 but channels 10 and 13 in the valve remain closed whereby access to the filter is undisturbed. Further rotation of the valve to position shown in Fig. 4 permits unfiltered water to pass as before to the main and also by the opening 14 to the salt receptacle and filter, and back by the pipe 8, channels 9, 13, to waste 15. The handle may now be returned to the position, Fig. 1, and retained there, as long as required until a fresh cycle is necessary. Instead of a handle for operating the slide a suitable worm gear may be employed.
