Title: Improvements in and relating to bearings
IPC: F16C25/02
Filed: 1934-06-01
Abstract: 422,532. Journal bearings. POLLAK, J. E., 20, Holborn, London.-(B÷hm, P. ; 35, Neue Mainzerstrasse, Frankfort-on-Main, Germany) June 1, 1934, No. 16406. [Class 12 (i)], An adjustable journal bearing has a number of annular discs b, c, g, the majority of which have a relatively large play with respect to the shaft a, and the bearing housing d and all of which are coupled together by pins e engaging apertures f so that the discs can be rotated eccentrically to take up the play in the bearing. The remaining discs b, g, which have small play with respect to the parts a, d, serve to centre the shaft. The pin e and aperture f of each disc are at diametrically opposite points so that when the discs have been rotated eccentrically by means of a tool engaging the disc g, the pins e are in planes slightly offset from each other, and the succeeding rings bear on the shaft at approximately diametric points. The end ring b is fixed and, when the bearing play has been taken up, the rings are clamped by a screw ring h. The bearing may be made self-adjusting by connecting the end rings, or one of the end rings and the housing, by a coil spring which tends to rotate the rings eccentrically on the shaft. The crescent-shaped spaces between the rings and the shaft facilitate lubrication, which may be further aided by a loose or vaned ring in a space formed in two of the bearing rings. Axial projections on either side of the bearing parts of the rings enable a greater bearing surface to be obtained with a smaller number of discs.

Title: Apparatus for determination of chemicals in a sample stream
IPC: G01N27/28
Filed: 1974-04-16
Abstract: 1459693 Determination of stream constituents using a centrifugal separator KESKUSLABORATORIO - CENTRALLABORATORIUM AB OY 16 April 1974 [17 April 1973] 16562/74 Heading G1B [Also in Divisions B2 and G3]  Apparatus for the determination of a chemical in a sample flow through tube 1 comprises a cyclone separator having a generally conical chamber, a tangential inlet adjacent the larger end of the chamber, a first outlet at the smaller end of the chamber and a second outlet at the larger end of the chamber, and electrodes 8, 8<SP>1</SP> located at or adjacent to but downstream of the first outlet. The sample stream is mixed with electrolyte flowing in tube 2. The lighter and heavier components of the mixed streams leave the cyclone separator through needle valve 7 and tube 7<SP>1</SP> and through outlet 9 respectively. In an Example, the apparatus is used in the determination of chlorine chemicals in a bleaching liquor, when the electrolyte may be hydrochloric acid or spent liquor from the chlorination stage of the bleaching, the chlorine having been removed from the liquor. The measurements may be used to control the supply of fresh oxidant to the liquor (see Group G3). In the apparatus of Fig. 2, a spent oxidizing liquor in line 10 is mixed in chamber 11 with fresh oxidant from line 25 and the resulting liquor is recycled through line 13. A sample of the liquor is taken through line 14 from a point downstream (as shown) or upstream of chamber 11 Figs. 3 and 4 (not shown), its pH is measured at 15 and at 18 it is mixed with electrolyte from supply 16 and passed to the determination device (19) described above, the sample then being discharged at 20. The voltametric measurement from line 19 is fed to oxidant addition unit 23 for control of oxidant flow at 24.

Title: Improvements in and relating to valve control for piston steam engines
IPC: F01L31/16
Filed: 1933-06-10
Abstract: 413,485. Steam engines. LENTZ, H., 74, Kurfurstendamm, Halensee, Berlin. June 10, 1933, No. 16678. [Class 122 (ii).] In locomotive and other steam engines wherein the admission and exhaust valves 6, 9 are arranged at the cylinder ends and the valves are operated by two-armed rocking cams 18, the cams have lifting-surfaces constructed like rolling levers, and the surfaces extend substantially through the fulcrums of the cams. The valves are arranged coaxially. The sleeve 5 which forms the seat of valve 6 has a cover 7 which forms a seat for the exhaust valve 9. The hollow spindle 10 of the valve 6 slides in a steam chamber 13, and has a perforated bottom 101 through which steam passes to act on the hollow spindle of the exhaust valve 9. The cylinder has a central steam chest 3 and end exhaust chambers 4. The cam 18 has lifting-faces 18a, 18b which act through levers 19, 20 upon a spindle 15 and a sleeve 14 to operate the valves. The cam 18 is operated by a rocking-arm 21 which is connected to the rocking-arm operating the cam at the other end of the cylinder. The closing pressures on the valves at one end of the cylinder are transmitted through the valve-gear to the cam at that end and assists in opening the other valves. A modification is described wherein the levers 19, 20 are dispensed with. In the construction shown in Fig. 3, the lever 19 gives the admission valve a longer stroke. In a further modification the valve spindles are formed as differential pistons to which fluid-pressure is supplied to hold them to the operating-gear. In a further modification, double-beat drop valves are arranged side by side in covers at the ends of the valve-chest. Their spindles bear against pistons in bores to which steam is supplied. The covers of the admission and exhaust valves at each end of the cylinder, constitute a single casing connected by a transverse casting housing the cam.

IPC: G21C3/04
Filed: 1967-04-12
Abstract: 1,219,264. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 27 March, 1968 [12 April, 1967], No. 16875/67. Heading G6C. A fuel pin for a fuel element for a fast breeder nuclear reactor comprises an external metallic sheath containing ceramic nuclear fuel material, characterized in that the sheath has a multiplicity of longitudinally spaced regions of reduced diameter along its length, each such region having a uniform reduction of diameter over a length of the sheath at least equal to the overall unreduced diameter of the sheath, the ceramic nuclear fuel material at least in the regions of reduced diameter of the sheath being of vibrocompacted ceramic nuclear fuel powder, whereby that fuel material in register with the regions of reduced diameter of the sheath has a decreased heat rating with a less tendency to melt on occurrence of a temperature excursion of the reactor, thus providing barriers against reorientation of the fuel within the pin. Such a fuel pin may consist of a stainless steel sheath 2 containing both fissile fuel 3 and fertile fuel 4, the former consisting of UO 2 /PuO 2  powder vibrocompacted to 80% theoretical density and the latter providing upper and lower axial breeder regions and consisting of solid pellets 5 and annular pellets 6, respectively. The fissile fuel 3 is separated from the pellets 5 by a solid stainless steel spacer 7 and from the pellets 6 by an annular stainless steel spacer 8 containing a fine filter 9 of stainless steel wool. A spacer 10 similar to the spacer 8 but containing a coarser filter 11 separates the breeder pellets 6 from a chamber 12 for the collection of gaseous fission products. The end regions of the sheath 2 are provided with inner sleeves 13, 14 and are swaged down and sealed with end welds 15, 16. Prior to the loading of the fuel, three spaced diameter reductions 19 are formed in the sheath 2 by cold rotary butt swaging, cold planetary swaging, or the use of high energy shock waves and employing within the sheath a mandrel of suitable profile. In an alternative construction, a stack of fissile fuel pellets is loaded into the sheath over a portion only of the fuelled length of the pin, the sheath is subjected to local swaging just above the top of the stack of pellets to effect a reduction of diameter, fissile fuel in powder form is loaded into the sheath in the region of diameter reduction and vibrocompacted, another stack of fuel pellets is loaded above the compacted powder, and the operations of diameter reduction, powder loading, powder compaction, and pellet loading are repeated until the fuelled length of the pin is fully occupied.
