Title: Method and apparatus for shaft alignment
IPC: G01B7/31
Filed: 1973-03-13
Abstract: 1400965 Aligning shafts V R DOOD 13 March 1973 [4 April 1972 9 March 1973] 12121/73 Heading G1M A method of aligning two shafts under thermal equilibrium operating conditions comprises, first setting the shafts up at ambient conditions and measuring their misalignment, then measuring their misalignment at operative conditions, and finally compensating the alignment or offset aligning the shafts when they have returned to ambient conditions so that substantially coaxial alignment will occur under operating conditions. A known ambient condition alignment method called the face and hub method requires the shafts to be stationary and uncoupled so that dial indicators may be fixed on the end of one shaft to register with the coupling end-face and the end periphery of the other shaft, these readings then being used to determine misalignment angles. In a preferred ambient condition alignment method called reverse dialling, the shafts must be stationary but may still be coupled, a single dial gauge being fixed to the end of one shaft so that it rests on and reads the periphery of the end of the other shaft and gives readings at various angular positions. The gauge is then fixed to the other shaft and reverse readings taken. In the apparatus of Fig. 1 the driven shaft housing 14 supports at one end 54 a rigidly braced triangular bar arrangement 32, see also Fig. 2, (not shown) comprising tubes 38, 39, 40 which extend along the shafts 16, 18 and support blocks 70, 72. A second rigidly braced triangular bar arrangement 52 is mounted at one end 34 on the driver shaft housing 12 and is spaced apart from the bar arrangement 32 so that brackets 71, 81 clamped thereto support sets of non- contacting transducer probes 74, 82, 76, 84 in spaced apart relation to the blocks 70, 72. By this means relative movement between the bar arrangements due to shaft misalignment causes the transducers to emit signals which are amplified and displayed, see Fig. 3, to indicate the extent of movement in mils. By employing this apparatus to determine misalignment under operative conditions, and the known apparatus for the ambient conditions, compensation or cold counteracting adjustments may be made so that substantially coaxial alignment may be obtained in operation. In the apparatus of Fig. 7, (not shown), each bar arrangement carries a block and a probe. In Fig. 8 triangular alignment bar arrangements 140, 168 support face plates 150, 174. A block 152, Fig. 9 extending from 150 passes freely through 174 and has faces 154, 156 which co-operate with probes 198, 202 mounted on the bar arrangement 168 to measure relative vertical and horizontal movement, and probes 176, 178, 180, 181 spaced on the ring plate 174 co-operate with the surface 151 of the plate 150 to indicate relative angular displacement of the shafts 16, 18.

The opening 45 may be provided with a detachable charging member 46. The plate 44 is carried by an arm 50 fixed to a vertical rock-shaft 51 and is normally pressed into position over a mould 32 by a spring 54 but is moved into register with the shoot 40 by the cylinders 30 engaging a cam 62 fixed to a rock-arm 63 and engaging a set screw 61 on a cam follower 60 fixed on the shaft 51. The charging plate 44 is provided with a shutter plate 70 mounted on an arm 71 secured to a shutter arm 72 pivoted to the arm 50.

Title: Improvements in phosphors
IPC: C09K11/61
Filed: 1946-04-23
Abstract: 649,503. Luminescent material. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 23, 1946, No. 12305. Convention date, April 19, 1945. [Class 39 (i)] A long persistence phosphor having an exponential decay characteristic particularly for forming a fluorescent screen for a cathoderay tube comprises zinc fluoride and/or magnesium fluoride activated with manganese. When the phosphor comprises both zinc and magnesium fluorides they may be co-crystallized or a mechanical mixture of the fluorides may be employed. A method of making the phosphor comprises heating a manganese compound with a mixture of hydrofluoric acid and zinc oxide and/or magnesium oxide. In one example 20 grs. of chemically pure zinc oxide are treated with concentrated aqueous hydrofluoric acid in excess and mixed with 0.1 grs. of magnanese chloride. The mixture is dried and heated to about 700‹ C. in a platinum crucible for about twenty minutes and is then preferably ground and heated at 700‹ C. until excess hydrofluoric acid is driven off. The product is then ground to fine powder such as by ball milling. In another example, five grs. of magnesium oxide can be used instead of zinc oxide and 0.05 grs. of manganese chloride with aqueous hydrofluoric acid. If a fluorescent screen is formed by settling the phosphor from a liquid, a non-aqueous liquid should be employed. Specifications 492,722, [Group XX], and 493,868 are referred to. Reference has been directed by the Comptroller to Specification 579,749.

Interlocking overlapping wall facing tiles 2 are secured to horizontally spaced channel section vertical strips 10 by diverging grooves 3 engaging complementary hooks 14 in the flanges 13 of the strip, pressing down of the tiles on the hooks causing resilient deformation of the hook from the obtuse, angle α shown for lower tile in Fig. 3 towards a right angle shown for upper tile in figure 3, so that the resiliency of the strip presses the tile towards the wall and prevents rattling thereof. The flanges 13 may initially, be at acute angles to the web 11 but this makes fixing of the web to the wall by nails 12 more difficult. The hooks may start immediately at the edge of the web if the tiles need to be closer to the wall or the webs 11 may be secured in spaced relation to the wall if the spacing needs to be larger. The strips may be cut from metal strip and then bent to shape or moulded from glass fibre reinforced plastics.

A transition between corrugated waveguides of different helical angle or between a corrugated waveguide and a conventional waveguide is effected by a gradual decrease in the depth of the corrugations. The depth may be reduced continuously or in steps. Where the corrugated waveguide is circular or elliptical and the other waveguide rectangular or square, a conventional transition section may be used in addition to the present transition. Two circular waveguides having helical corrugations of opposite sense may be joined by a smooth intermediate section connected on either side to transition sections in accordance with the invention. The invention is applicable to bellows-type waveguides as well as to helically corrugated ones.

Title: Method of and apparatus for separating oil from animal material
IPC: C11B1/02
Filed: 1945-05-18
Abstract: <PICT:0611614/III/1> Oil is separated from oil-containing animal tissue material, for example cod liver or whole herring, by first treating the material without breaking down the cell walls to render the protein substantially incapable of forming an emulsion with water and oil, then mechanically comminuting the material to rupture the cells and finally separating the oil mechanically.  The protein is rendered substantially incapable of forming an emulsion by treatment with formaldehyde or paraformaldehyde or by heat treatment but, where sufficient heat is generated during the mechanical comminution to achieve the desired result, this treatment is dispensed with.  After comminution and before mechanical separation of the oil, additional oil which is entirely or relatively devoid of vitamin potency, for example herring oil or a vegetable oil such as corn oil, may be added to the comminuted material, especially when treating swordfish liver or other material with low oil content.  In the Figure, the animal material, such as oil-containing liver, which has been treated to render the protein substantially incapable of forming an emulsion with water and oil, is taken from tank 1, via conveyer 2, hopper 3 and conveyer 4 to the grinding apparatus 5.  Coarse paste is discharged from outlet 6 into colloid mill 10 and fine paste from the colloid mill is received in tank 12.  Pump 14 takes paste from tank 12 and delivers it through pipe 15 to flotation tank 16, while water from pipe 23 sprays into tank 16 through perforated header 22.  Upon rotating shaft 18, depending stirring blades 20 pass between the fixed upstanding blades 21 and oil flotation occurs, the separated oil running down spillway 24.  The oil may be passed to vacuum dehydrating stripping tower 25, and the dehydrated oil collecting in receiver 27 may be passed to filter press 28.  Instead of separating the oil by flotation, the comminuted material may be stirred, passed over a series of baffles or otherwise treated to cause the oil globules to tumble into contact with each other, and then centrifuged, pressed, filtered or similarly manipulated to separate the oil. Specification 514,424 is referred to.
