Title: Improved device for dispensing liquids
IPC: B65B3/00
Filed: 1945-10-22
Abstract: 599,954. Delivering measured quantities. TIDMARSH, A. Oct. 22, 1945, No. 27700. [Class 106 (v)] [Also in Groups XXXV and XL] Fig. 1 shows a device for dispensing liquids in which the outlet of a measuring tube a closed by an air vessel b is regulated by a magnetic valve c<2>, while the inlet tube d from an elevated reservoir e is regulated by a similar valve d<2>. The valves are operable by solenoids c<3>, d<3>, and for automatic valve control, photoelectric means may be used as shown in Fig. 2. Valve d<2> being opened by solenoid d<3>, the liquid rises to the level of photocell f<1> and concentrates light upon it, reducing the grid bias of triode h, and increasing its anode current to operate relay i. The valve d<2> closes, and the lower photocell f<2> is switched into the triode grid circuit. On closure of switch l, relay k operates, energising solenoid c<3> and opening the outlet valve c<2>. When the liquid level has fallen below the photocell f<2>, insufficient light falls on the cells for the triode to remain conducting, and relays i and k release successively, closing valve C<SP>2> and opening valve d<2>, until the level reaches cell f<1> and the apparatus is reset for a further operation.

As reducing compounds there are specified ascorbic acid and thiourea. The examples describe the following processes: (1) reacting polyvinyl tert. butyl carbamate with hydrochloric acid to produce polyvinylamine hydrochloride which is reacted with eosine lactone and then used in a photopolymerization reaction with acrylamide in the presence of ascorbic acid; (2) as in (1) but using acrylic acid as the grafting monomer; (3) as in (1) but using acrylonitrile as the grafting monomer; (4) as in (1) but using styrene as the grafting monomer; (5) as in (1) followed by the grafting of acrylic acid in a second polymerization stage; (6) polymethyl methacrylate containing terminal amino groups is reacted with eosine lactone and then block photopolymerized with styrene in the presence of thiourea; and (7) as in (6) but using acrylamide as the monomer to form the block copolymer.  In the above processes water or acetic acid is used as a solvent for the reactants.  The block copolymer of Example (6) may be hydrolysed to yield a mixture of styrene and methyl methacrylate homopolymers.
Patent GB-766186-A (GB)
Title: "improvements in or relating to sintering metallic powders"
IPC: B22F3/00
Filed: 1953-10-16
Abstract: 766,186. Powder metallurgy. METAL-LURGIE DES POUDRES. Oct. 1, 1954 [Oct. 16,1953], No. 28645/53. Class 83 (4). In a process for sintering a metallic powder having a melting point of at least 600‹ C., the powder is mixed with an organic lubricant, the mixture is subjected to pressure to form a compact which is then treated to remove substantially all the lubricant and the compact is then sintered in a non-oxidizing atmosphere in the presence of a reacting agent which reacts with the metal to form a compound which is subsequently decomposed to deposit metal on the particles of the compact before the sintering is completed. The compression of the powders to form a compact is generally effected at a pressure of between 10 and 150 kg. per sq. mm. The lubricant is used in the proportion of up to 2 per cent by weight of the metallic powder and is preferably a stearate, such as zinc stearate, but it may be an oil or soap dissolved in a volatile solvent. The lubricant may be removed by heat alone in the presence of an inert gas at temperatures between 250‹ and 650‹ C. or by heating at similar temperatures in the presence of a gas or vapour, such as air or steam, which reacts with the lubricant. If the lubricant is removed from the compacts by heating in air, the compacts are preferably de-oxidized by heating them above 800‹ C. in an atmosphere of cracked ammonia. When the lubricant is removed by means of a solvent the compacts may be wetted with a liquid such as perchlorethylene or carbon tetrachloride, the solvent being evaporated by heating the compacts to a temperature generally below 200‹ C. The metallic compound formed in the compact is preferably liquefied before the decomposition is effected and its formation on the compact may be effected by introducing a reacting agent such as ammonium or hydrogen halide or phosphorus sulphide. The process is applicable to pure metallic powders or to powders of alloys, such as tungsten, molybdenum, copper, nickel, cobalt, aluminium, stainless steel, cast iron, iron-chromium alloys, ironsilicon alloys, iron - aluminium alloys, aluminium-nickel-iron alloys or to mixtures of powders. The powders have a particle size finer than 350 mesh (B.S.S.). The compacts may be sintered in boxes of iron partially sealed by a joint of alumina or the furnace illustrated may be used. The furnace has baffles 9 and 10 and trays 11 carry the compacts from 12 to 13. Pure hydrogen introduced at X to form an inert atmosphere in the area of the cooling jacket 6 is partly removed at Y and re-introduced at Z after having been charged with the reacting agent and the hydrogen and agent are largely removed at P; hydrogen saturated with steam for the removal of the lubricant is introduced at Q and removed at S.

Title: Improvements in or relating to methods of and apparatus for descaling metal strip
IPC: B21B45/06
Filed: 1938-10-04
Abstract: 520,129. Cleaning metals. STEVENS, A. H. (Wean Engineering Co., Inc.). Oct. 4, 1938, No. 28795. [Class 82 (ii)] A method of descaling coiled strip includes uncoiling a length of strip, advancing the leading end thereof, and passing the strip substantially continuously through a descaling zone, attaching the leading end of a second length to the trailing end of the first, shearing the trailing end of the first length from the leading end of the second after the latter has traversed said zone, while maintaining continuous movement of the second length through said descaling zone, and accumulating an excess of strip between said descaling zone and the point of shearing. After the leading length has been sheared from the following length, the trailing end of the former is advanced at greater speed than normal to withdraw up the accumulated excess of the leading length from the apparatus. The leading end of the second length is then passed through the withdrawing rolls at greater speed than normal to take up the accumulated excess of the second length. In the form shown, strip is uncoiled by pinch rolls 16, then passes over conveyer section 19, through shear 18, over the tilting conveyer section 20, under " hold down " 24, through " stitcher " 23, pinch rolls 25, and looping pit 28, is pulled by pinch rolls 29 under motor-controlling roll 33 and through one or more pickling baths 36 and one or more washing baths 37. The strip then passes through warm-air drier 39 over conveyer 40 to pinch rolls 41, under the adjustable roll 45 in the second looping.pit, 44, to pinch rolls 48, to shear 50 and finally to pinch rolls 55 feeding the strip to the recoiler 57. The strip passes to the shear 18, is stopped, and then cut square, the reject falling beneath the conveyer 20 which is momentarily tilted. It is then fed rapidly forward so that excess accumulates in the looping pits 28 and 44 and is wound on to the recoiler 57. A second strip is sheared, then fed to the " stitcher " 23 where it overlaps the end of the first strip, is stitched by punching whilst being tensioned between " hold down " 24 and driving rolls 25. Rolls 25 are then retracted and the stitch passes to where it is stopped by stopping rolls 48, a cut made ahead of the stitch, the trailing end ahead wound quickly on to the recoiler, a cut 'made behind the stitch and the stitch rejected, and the rolls 48 restarted and the second strip rapidly recoiled so as to take up the slack in the looping pit. The motors of rolls 16 and 25 may have independent starting means and common means for equalising speed. The motors of rolls 29 and 41 have common starting means and independent means for speed control. The motors of rolls 48 and 55 are completely independent. Rolls 32 unfold any transverse bends formed in the strip while in the looping pit 28.
