Title: Improvements in or relating to the manufacture of pneumatic tyres
IPC: B29D30/34
Filed: 1938-12-23
Abstract: 524,019. Moulding wheel tyres. DUNLOP RUBBER CO., Ltd., WILLSHAW, H., 'SMITH, H., and BROADBENT, F. G. Dec. 23, 1938, No. 37408. [Class 87 '(ii)] In apparatus for effecting the step of bagging in the manufacture of pneumatic tyres comprising an upper movable platen 3 contacting with the tyre casing and a movable platform 7 for manipulating the curing bag, motive power is directed to the former and is transmitted therefrom to the latter by mechanical linkage to produce automatic inter-relation of operation between the two. The platen 3 is carried by a ram operating in a cylinder 1 and is associated with a pair of links 11 having slots 27 engaging a pair of links 14 through the pins 15 The platform 7 reciprocates in a usual well 8 and is provided with a supporting table 10 for the tyre casing. The links 14 are interconnected with the piston rod 7a of the platform 7 by means of a pivoted connecting rod 19, a pair of links 20 pivoted at 21, and a pair of shackle links 25 connected to the piston rod 7a. The slots 27 are provided with heightadjustable pads 28 shaped to fit the pins 15, this adjustability enabling the time sequence of operation to be varied, and no movement. of the platform 7 ensues until the tyre casing is sufficiently expanded by the platen moving the distance of the slots 27. After the curing bag has been'expelled into the tyre casing, further movement downwardly of the platen 3 is allowed for by springs 33. Movement of the platen 3 is effected by hydraulic pressure applied to the lower or upper side of the ram and is controlled by a pair of valves having stems a<SP>1</SP>, a<SP>2</SP>, connected to a valve operating rod d. The operation is started by raising a lever f which lifts the rod d, opens valve a2 and sets a detent g to keep the rod d in its raised position. The platen 3 now descends, followed by the movement of platform 7, pressure-air also being admitted to the tyre casing a valve being operated by trip mechanism for this purpose. A striker g<SP>5</SP> on the platen arm b then disengages the detent g allowing the rod d to fall, thus closing valve a<SP>2</SP> and opening a<SP>1</SP>. The latter causes the platen 3 to rise and return to its neutral position.

Title: Process for decreasing the total sulphur content of claus off-gas
IPC: B01D53/77
Filed: 1975-09-15
Abstract: 1523734 Desulphurizing Claus off gases SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 15 Sept 1975 [16 Sept 1974] 37749/75 Heading C1A [Also in Divisions G2 and G3] Sulphur dioxide and other sulphur compounds in Claus off-gases are reduced to hydrogen sulphide by mixing with a hydrogen and/or carbon monoxide containing reducing gas and passing over a sulphided Group VI and/or Group VIII metal catalyst supported on an inorganic oxide carrier at a temperature above 175‹ C.; the hydrogen sulphide containing gas stream is then cooled at least partially by direct cooling with an aqueous quench stream and hydrogen sulphide is then removed from the cooled gas stream by contact with an adsorbent or absorbent; the sulphur dioxide content of the reduced gas stream is monitored by measurement of the pH of a portion of the quench stream which has been stripped with an intert gas so as to remove any hydrogen sulphide and carbon dioxide present, the signal generated by the measurement of the pH is then used to control the flow of either or both of the Claus off-gas and reducing gas over the catalyst.

Title: Improvements relating to the production of phosphate coatings on metallic surfaces
IPC: C23C22/13
Filed: 1958-11-28
Abstract: Metallic surfaces are cleaned by spraying them with an aqueous solution which has a total alkalinity of 2-36 points and a ratio of free to total alkalinity in the range 0.05-0.5 and which contains 0.007-0.83% w/v octyl phenoxy polyethoxy ethanol having 5-8 oxyethylene groups.  The clean surfaces are then phosphated by means of a zinc phosphate solution (see Group II).  The cleaning solution is used at a temperature below 100 DEG F. on surfaces of, for example, iron, steel zinc, aluminium and copper. A suitable solution is made by diluting with water 0.1-10 oz./U.S. gallon of a material consisting, by weight, of trisodium phosphate 15-30 parts, borax 25-40 parts, t-ocytl phenoxy polyethoxy ethanol 1-5 parts, sodium nitrite 0-12 parts, pine oil 0-25 parts, and, optionally, sodium bicarbonate and 0.28-0.6 parts titanium (as titanyl sulphate).ALSO:A process of cold cleaning (i.e. below 100 DEG F.) and cold phosphating (i.e. at 110 DEG  F. or below) metallic surfaces comprises the steps of forcefully spraying against the surfaces an aqueous alkaline solution having a total alkalinity of 2-36 points and a ratio of free alkalinity to total alkalinity in the range 0.05 to 0.5 and containing an octyl phenoxy polyethoxy ethanol having 5-8 oxyethylene groups, and thereafter contacting the surfaces with an aqueous acidic zinc phosphate coating solution.  The cleaning solution may contain trisodium phosphate, borax, sodium bicarbonate, sodium nitrite, pine oil and titanium, and preferably contains 0.007-0.83% w/v octyl phenoxy polyethoxy ethanol.  If the cleaning solution does not contain titanium, a titanium-containing disodium phosphate solution may be applied to the metallic surfaces as a modification of the water-rinsing step following the cleaning step or in a separate treatment step.  The phosphate coating solution is preferably based on zinc dihydrogen phosphate and may contain calcium, nickel, nitrate, nitrite, bromate, sulphite, m-nitrobenzene sulphonate, picric acid and sodium ethylene diamine tetraacetate.  The phosphate coating may be rinsed in dilute chromic acid solution.  Metallic surfaces which may be treated include those of iron, steel, zinc, aluminium and copper.

Abstract: 1,234,839. Hardening layer-forming materials for photographic purposes. CIBA-GEIGY A. G. Aug.14, 1968 [Aug.22, 1967], No.38856/68. Heading G2C. Photographic colloid layers in photographic materials are hardened by incorporating in the casting solution for at least one of said layers (a) a slowly after-hardening agent and (b) a rapidly hardening agent the hardening action of which declines on storage. The hardeners (a) are preferably derived from two classes of hardeners; (a 1 ) a colourless halo 1, 3, 5-triazine compound which contains at least one acid group conferring solubility in water, examples of which compounds are disclosed, or (a 2 ) a compound which is at most slightly coloured which contains at least one sulphonic acid group and two α-halogenacrylamide residues. The rapidhardening agents of class (b) exemplified are N, #-chloro-propionyl N<SP>1</SP> -acryloylurea, N-acryloyl 2, 3-epoxypropyl carbamate, N, #-chloropropionyl 2, 3-epoxypropyl carbamate, N, #-chloropropionyl N<SP>1</SP>, N -ethylene urea, N, #-chloropropionyl formylmethyl carbamate and N, N<SP>1</SP> -bis-acryloyl urea. The layer-forming materials which are hardened may be polyvinyl alcohol, polyvinyl pynolidone and especially gelatine. The hardeners may, before drying, diffuse from one layer into another layer of a multi-layer casting, and hence all the layers of a multi-layer casting may be hardened by adding a hardener mixture only to some of the layers or by adding one hardener to some of the layers and another hardener to other layers.

In a reactor employing a suspension of nuclear fuel in either light or heavy water, fission products are removed by the addition of solid particles to the suspension which absorb the products and which are separated from the suspension by a hydrocyclone. The absorbing solid particles may be carbon or silica gel. The reaction chamber is surrounded by a moderator structure of beryllium oxide blocks which is itself surrounded by a reflector of carbon blocks, the whole being enclosed in a pressure vessel and a concrete biological shield. To prevent boiling, the system is subject to the pressure of either hydrogen or deuterium which is also applied to the interior of the pressure vessel to prevent leakage.
