Title: Sensitive elements for colour photography and methods for the production thereof
IPC: G03C7/384
Filed: 1937-10-14
Abstract: 503,845. Photographic sensitive materials. KODAK, Ltd. Oct. 14, 1937, No. 27930. Convention date, Oct. 14, 1936. [Class 98 (ii)] [Also in Group IV] A silver halide emulsion layer is formed by using a compound produced by reacting a soluble silver salt with a pyrazolone and treating the product with a quantity of halide at least equivalent to the whole of the silver present. Suitable pyrazolones are phenyl methyl pyrazolone, bromphenylmethyl pyrazolone, #- naphthylmethyl pyrazolone, and thiopyrazolones such as 1-phenyl-3-methyl-5-thiopyrazolone. In one example, silver nitrate is precipitated with 1-phenyl-3-methyl-5-pyrazolone and the precipitate washed, dried, and made up into an emulsion with gelatine and potassium bromide. The emulsion is set, shredded, remelted and coated on a plate. On development with diethyl-p-phenylene diamine, sodium sulphite, and borax, a magenta image is formed. Other suitable developers are methyl phenylene diamine and 2 : 5-dianuno-toluene. In place of gelatine, agar-agar, collodion, or hydrophilic cellulose organic esters may be used and potassium bromide may be replaced by other alkali halides or by halogen acids. Separate layers containing different colour formers may be used in multicolour processes. Specification 376,794 is referred to. The Specification as open to inspection under Sect. 91 describes also the use of diketohydrindene, thioindoxyl, thioindoxyl carboxylic acid, chlorindoxyl, coumarones such as cyanacetyl coumarone, cyanoacetamides such as cyanoacetanilide, acetoacetamides such as acetoacetanilide, and ketones containing a reactive methylene group such as acetyl acetone. This subject-matter does not appear in the Specification as accepted.

Title: Process and apparatus for the non-combustible recovery of waste gases emanating from the refinery of pig iron by oxygen
IPC: C21C5/38
Filed: 1962-07-20
Abstract: 1,017,505. Controlling draught; confining and removing dust and fumes in industrial processes. INSTITUT DE RECHERCHES DE LA SIDERURGIE FRANCAISE. July 20, 1962 [July 28, 1961; Aug. 18, 1961; March 15, 1962], No. 27952/62. Headings F4B and F4X. [Also in Division G3] In a process for the non-combustible recovery of gases from the refining of pig iron by pure oxygen using a hood 2 at a predetermined distance above a converter 1, and a discharge pipe 5 for the collected gases wherein the draught is regulated to prevent air leaks and gas escapes at the hood, the temperature at at least one level in the lower part of the hood is measured to determine the position of the gas level, and the draught controlling means in the discharge pipe is operated so as to maintain the measured temperature within predetermined limits, and thus maintain the gas level at a substantially constant position. As shown, oxygen, possibly with pulverulent materials in suspension, is blown on to the pig iron 4 through a water-cooled lance 3, the resulting gases passing from the converter 1 into the hood 2, also water cooled, and through the discharge pipe 5 to a wet dust collector 6, and an exhauster fan 7 to a combustion chimney 8. Tubes 17 rising from points spaced around the lower part of the hood 2 are connected to a common suction pipe 18 and contain two inertia thermocouples 10a. The signals from the thermocouples are used to control a damper 9 in the discharge pipe, by means of a suitable control system (see Division G3) so that if the draught is insufficient, and the hot gases from the converter tend to impinge lower down in the hood and to spill into the atmosphere, the increased temperature at the thermocouples causes the damper to open, while excessive draught, which would tend to draw in ambient air and lead to combustion in the recovery system, causes lower thermocouple temperatures and hence, an increased blocking of the draught by the damper 9. To prevent spurious signals to the control system due to local heating caused by overflowing slag, thermocouples may be arranged to sense the temperatures at two levels in the hood, control being in response to one level only, except when the temperature difference between the two levels becomes zero, or of opposite sign to normal, in which case the control is blocked, e.g. by an electromagnet which cuts the damper 9 off from the control system and holds it in position. An alternative method of detecting gas leakage from the hood is to place flame-detecting means, such as thermocouples, round the outside of the lower portion of the hood 2, Fig. 1, not shown, so that when these detect a higher than normal temperature the damper 9 opening is increased. The signals from the thermocouples are summed, and control is only effected when the total e.m.f. rises above a predetermined value.

Abstract: 518,800. Fluid-pressure servomotor systems. SOC. GENERALE DES CARBURATEURS ZENITH. Sept. 30, 1938, No. 28463. Convention date. Oct. 1, 1937. [Class 135] [Also in Group XXVII] In a device for controlling an engine throttle by means of the pilot's control lever and by means limiting the maximum opening, two rods pivoted to each other are connected, one to the throttle and the other to the pilot's control, at points which are equidistant from the common pivot and are compelled to move along fixed paths intersecting one another, one of the rods being further connected with the maximum opening control. Figure 4 shows one form in which the two rods 4 and 5 pivoted together at 6 are connected respectively to the throttle 2 and to the pilot's control lever 10 through rods 21, 26 which slide in fixed guides 23, 28 the connecting pins 25, 30 sliding in slots 24, 29. An extension of the rod 4 is also connected by a pin-and-slot device 41, 42 to a maximum opening control comprising a servomotor piston 36 with a valve 34 connected to a capsule 31 in a chamber subjected to the pressure in the inlet pipe. The device is constructed so that when the pilot's lever is in the position which closes the throttle, both of the pins 25, 30 are at the intersection of the slots 24, 29 and the movements of the piston 36 have no action on the throttle. In a modification, the rods 4, 5 are connected directly to the links 22, 27 and the points of connection therewith are guided in fixed curved slots. In another form, the rods 4, 5 are connected directly to the levers 3, 10 so that their points of connection are contrained to move in circular arcs. The maximum opening control may be actuated by a manometric capsule varying with atmospheric pressure, or by a speed governor. In the latter case, the device is arranged so that the pilot's control has no effect on the throttle when the maximum opening control is moved into the position which closes the throttle . This is effected by connecting the link 27 to the pilot's lever 10 at a point which is situated at a distance from the axis of the lever 10 equal to the length of the rods 4, 5.

Abstract: 6 0 3,6 7 9. Conical mills. HAMBLIN, W. G. Oct. 27, 1945, No. 28479. [Class 59] In a grinding-mill as described in Specification 382,705 in which the minimum distance between two grinding surfaces is determined by an adjustable abutment, the grinding pressure being maintained by spring means, the shaft 7 carrying the rotary grinding-member 3 is withdrawably splined into a worm or like gear wheel 8 mounted in a gear box 6 on the base frame 4. The housing 1 for the grinding members 3, 18 is supported from the base 4 by uprights 5, and has a depending sleeve portion 17 which slidably engages a sleeve 13 containing a spring 12, which applies the grinding pressure, a ballbearing 16 engaging a shoulder on the shaft 7 and a collar 14 pinned at 15 to the shaft 7 between which collar and a thrust ball-bearing, the spring 12 is confined. The force of the spring is adjusted by rotating, by means of a tommy-bar, a screwed member 10 which is threaded in a bush 11 in the lug 9 of the gear box 6. The sleeve 17 encloses, in vertically slidable relation, a ball bearing and dust-excluding sleeves and washers. The minimum distance between the members 3, 18 is determined by a bifurcated lever 19 which bears on projections 20 on the sleeve 13 and is adjusted by a handwheel 24 and a screw 22. The uprights 5 carry also a mixer above, and in vertical alignment with, the hopper 25 of the grinder, the bottom end 29 of the mixer shaft being squared to engage a socket 30 on the grinder shaft. The mixer can thus be lifted vertically away from the grinder to permit the hopper 25, which is mounted on a member 26 hinged to the housing 1, to be swung aside. The grinder 3 and its shaft may, after removal of the pin 15, then be removed by lifting vertically. A cooling liquid or steam may be circulated in channels 27. A scraper 32, shown as being horizontal but being vertical in practice, is held in a slot in a member 31 which is urged by a spring 35 towards the rotary member 3.
