Title: Process for producing mixed fertilizers and products thereof
IPC: C05B1/04
Filed: 1956-03-14
Abstract: <PICT:0829489/III/1> Phosphate fertilizers are made by treating calcium, sodium or potassium metaphosphate with a strong mineral acid in the presence of water (whereby the metaphosphate is hydrolysed to the primary o-phosphate and this is converted, wholly or partly, to the secondary phosphate), the acid product being then neutralised by adding an ammoniating agent.  The treatment of calcium metaphosphate with H2SO4 is excluded and forms the subject-matter of Specification 829,490.  The ratio mineral acid to metaphosphate is in the range 0.1 to 1.5.  Sulphuric Sulphuric acid is preferred, but hydrochloric, phosphoric or nitric acid may be used.  In a suitable apparatus, sulphuric acid and the ground metaphosphate are admitted to the upper tier 1, Fig. 2, of a pug mill, and water is added to form a slurry mixed by contra-rotating paddles.  The hot mixture is fed by a rotary agitator section 8 in a deep bed to a second tier pug mill 3 supplied from below with an ammoniating agent through a spray pipe 11.  An inlet above spray pipe 11 is supplied with a solution of KCl, K2SO4, (NH4)2SO4 or NH4NO3 which lowers the temperature of the ammoniated product.  If desired ammoniating agent is later added through an inlet 11a, and sulphuric acid at 11b to form ammonium sulphate in the mixture, which then passes to the third pug mill to form a dry crumbly solid.  As ammoniating agents, anhydrous ammonia, ammonium hydroxide, ammonium nitrate solution, ureaammonia, urea-formaldehyde-ammonia or mixtures of these solutions may be used.

Patent GB-671096-A (GB)
Title: Rolling mill for rings
Inventor: SALTER FRANK SIDNEY
IPC: B21H1/06
Filed: 1950-03-30
Abstract: 671,096. Rolling. LOEWY ENGINEERING CO., Ltd. March 30, 1950, No. 7996/50. Class 83 (iv). [Also in Group XXIX] A ring-rolling mill having an inner and an outer working roll has hydraulically controlled guide means which maintain a blank in position and which automatically recede when the blank expands during rolling. In one embodiment of the invention, 10 is an outer and 11 an inner power-driven working roll and 13 and 14 are guide rolls connected by cranks 22 and links 21 to a hydraulic ram 17 movable in a cylinder 18. The ram 17 is hollow at one end so as to form a cylinder 19 which co-operates with a stationary ram 20 to enable the ram 17 to be moved in both directions to open or close the guide rolls. The crank for roll 13 consists of two sections 221 and 222 hinged at 23, and section 221 carries a spring-loaded relief valve 25 which can be opened by a spring-loaded actuating rod 29 which engages a flange on the section 222. In operation, the guide rolls 13 and 14 are opened by supplying pressure fluid to cylinder 19 and when the blank has been placed over the working roll 11 the guide rolls are closed by supplying pressure fluid to cylinder 18. These operations are carried out by means of a lever 46 and valve block 36. When the guide roll 14 has contacted the blank the lever 46 is placed in the " Automatic " position which closes all valves in block 36 except valve 45 so that cylinder 18 is placed in communication with the exhaust line 38 whenever the valve 25 is opened. As the blank increases in diameter due to the rolling the section 222 of the crank 22 carrying roll 13 opens the valve 25 and the ram moves to accommodate the rolls 13 and 14 to the increased diameter at which point the movement of crank 22 closes the valve 25 and the rolls are temporarily locked in position again. As the roll 13 mainly operates valve 25 it has an initial clearance from the blank when the roll 14, which applies the guiding pressure, is touching the blank. In a further embodiment, guiding rolls 63, Fig. 2, are carried by levers 66, 67 respectively and one end of lever 66 is connected to a doubleacting ram 70 displaceable in a hydraulic cylinder 71 the rearward extension 72 of the ram 70 being displaceable in a cylinder 73 of smaller diameter than cylinder 71. Pivoted to the lever 67 is a casing 74 of a relief valve 75 which has two ports 76, 77 connected to cylinder 71 and an exhaust line 79. The relief valve actuating rod 84 is connected by a link 85 to an S-shaped lever 86 pivoted at 87, the lever 86 being in turn connected to the lever 66. Hydraulic pressure fluid is supplied to cylinder 71 through a valve block 92 controlled by a lever 98 and the guide rolls are controlled as previously described. The opening and closing of the relief valve may be controlled electrically.

Title: Reflex cameras
IPC: G03B17/17
Filed: 1976-03-01
Abstract: 1529017 Reflex cameras POLAROID CORP 1 March 1976 [3 March 1975] 07999/76 Heading G2A In a camera in which the light image entering the objective lens is reflected by a mirror on to the photo-sensitive film, the size of the mirror, its spacing from the exposure plane and its inclination thereto are chosen so as to obviate flare or ghost image effects. These effects are caused by light incident on the image plane being reflected therefrom, and then reflected back again from the mirror. Fig. 6 shows a camera of the self-processing type, the film units being housed in a container 58. The design is such that a light ray entering along the optical axis of the lens 32 parallel to the bottom wall of the camera is reflected from the mirror 34 so as to fall on the exposure area at point C, approximately central thereof, and at approximately normal incidence (actually 88 degrees as shown because of the 2 degrees divergence between forward and rear walls 66 and 60 of the film container caused by accommodating the thickness of the rupturable containers 24). The film units are of the multi-layer type having an outer transparent sheet which acts as both an exposure window and a protective covering. It is usually made of a plastics material having a smooth and glossy outer surface. Thus a small proportion, perhaps 4%, of incident light is reflected, the remainder being transmitted. This reflected light falls on mirror 34 again, and is again reflected back towards the film. Normally it is now sufficiently weak for any flare or ghost image effects to be negligible. Under certain conditions, however, the effect may be noticeable. By choosing the distance h from point B on the mirror to point C on the film plane appropriately, and also the inclination α between mirror and film plane, and the size of the mirror in relation to the cone of image-bearing light required to fill the exposure window of the film unit, a geometrical configuration may be produced in which the unwanted reflected rays fall on locations outside the exposure area. The dimensional requirements are discussed with reference to Figs. 4 and 5 (not shown).

Title: Electrodes for electron discharge devices and methods of making same
IPC: H01J19/30
Filed: 1952-03-28
Abstract: 729,450. Electrode materials and processes therefor. STANDARD TELEPHONES & CABLES, Ltd. March 28, 1952 [May 23, 1951], No. 8000/52. Drawings to Specification. Class 39 (1). A metal electrode for an electron discharge device is coated with a mixture of carbon and one of the metals osmium, iridium or platinum. The coating destroys the electron-emitting properties of thorium vapour deposited on the electrode such as the grid of a thermionic valve by forming thorium carbide. An electrode of tantalum, molybdenum, zirconium, columbium, tungsten or hafnium is coated with a barrier layer of carbide such as a mixture of the carbides of the electrode metal and of another metal by a method such as that described in Specifications 660,076 and 729,449, which prevents chemical action between the electrode and the final coating which is applied by dipping, spraying or electrophoresis. A mixture of carbon and 10 per cent platinum is heated to 1700‹ C. in a vacuum for 1 minute. When grid temperatures do not exceed 1000‹ C. a barrier layer is not necessary. In the preferred method, platinized graphite, the preparation of which is described, is mixed with specified quantities of water and methyl cellulose binder which is milled and to which is added micronized graphite. The thickness of the coating including the binder corresponds to an increase in weight of 6 mg. per sq. cm.
