Title: Improvements in or relating to fluid-flow meters
IPC: G01F15/02
Filed: 1956-06-15
Abstract: 808,188. Variable-speed gear. SIEMENS & HALSKE A.G. June 15, 1956 [June 16, 1955], No. 18647/56. Class 80 (2). A fluid-flow meter has between its paddle wheel and its measuring apparatus a threeelement planetary gear, one element of which is driven directly from the paddle wheel and a second element of which is driven from the paddle wheel through a continuously variable ratio friction gear. The paddle wheel (not shown) is connected to a gear 1 meshing a gear 2 fast on a shaft 3. A gear 4, fast on the other end of the shaft 3, meshes a gear 6 carried by a bush 5 loose on a shaft 8, the gear 6 acting as a carrier for planet pinions 10, 11 fast on a spindle 7. The planet pinion 10 meshes a sun gear 9 fast with adisc 17 driven directly from the shaft 3 by a roller 16 engaging its underside and also engaging a friction disc 15 fast with the gear 4. The planet pinion 11 meshes a gear 12 fast on the shaft 8 which drives the meter mechanism (not shown) through gears 13, 14. The roller 16 can be moved axially to vary the ratio in the gearing by turning a screw 18. The sizes of the parts are so selected that adjustment of the screw 18 enables variations of ratio of the order of - 2 to + 3 per cent between the gears 1, 14 to be made. Thereby a corresponding adjustment of the nominal quantity indicated by the meter can be obtained. A calibrated dial, Fig. 3 (not shown), is attached to the screw 18.

Title: Improvements in and relating to the manufacture of paintable compositions based on the use of slaked lime as pigment
IPC: C04B28/10
Filed: 1949-07-15
Abstract: A water paint or colour wash is produced by incorporating with hot freshly slaked lime a crude soap obtained from wool grease by saponification with anhydrous caustic alkali by which means the unsaponifiable matter produced in the crude soap becomes a drying oil, with if required an additional quantity of this unsaponifiable matter which is separated by solvent extraction of soap obtained by a saponifying process as above set forth.  The crude soap may be converted into an ammonium soap emulsion or into a powdered crude magnesium soap before addition to the slaked lime.  The crude fatty acids of wool grease, obtained by splitting the soap from the anhydrous caustic alkali saponification of wool grease may be blended with the crude magnesium soap prepared from wool grease and then added to the slaked lime.  Specifications 470,715 and 553,322 are referred to.

Title: Fluid control means
Inventor: BRYANT TERENCE GRAHAM
IPC: G21C19/04
Filed: 1964-05-06
Abstract: 1,092,534. Regulating fluid-flow. NUCLEAR POWER PLANT CO. Ltd. and A. E.I.-JOHN THOMPSON NUCLEAR ENERGY CO. Ltd. [trading as NUCLEAR POWER GROUP]. Feb.11, 1965 [May 6, 1964], No.18916/64. Heading G3H. [Also in Division G6] Fluid-flow in a duct is controlled by a nozzle having convergent and divergent parts which are relatively movable in the direction of fluid-flow. The invention is of general application where it is desired to limit fluid-flow from a duct on removal of a resistance, and is particularly applicable to nuclear reactors. Fig. 3 shows a coolant channel 5 containing a fuel element 6 supported on a tubular member 4. The convergent part 2 of the nozzle is attached to the fuel element support 4 and the divergent part 3 is attached to the bottom of the fuel element 6, which may be one of a string of fuel elements. When the fuel element is removed from the channel with the reactor on load, the reduction in flow resistance thus caused is offset by the increased flow resistance at the convergent part consequent upon the simultaneous removal of the divergent part. The nozzle may also be of square or annular cross-section, and several may be employed in parallel in a single duct. Also, some of the fluidflow may by-pass the nozzle(s).

Title: Improvements relating to gas-blast electric circuit-breakers
Inventor: ELLIS NORMAN SADLER
IPC: H01H33/32
Filed: 1963-05-13
Abstract: 1,081,994. Gas blast switches. A. REYROLLE & CO. Ltd. May 13, 1964 [May 13, 1963], No. 18927/63. Heading H2B. In a multi-break gas-blast circuit breaker of the kind in which blast gas is discharged from a high pressure reservoir 20, across each break 61, 62 through a nozzle 34, 35 and into a cooling chamber 30 at lower pressure, the chamber or chambers 30 have metal or metallized surfaces 50 connected with the current path on one side of the break and co-operating with either a similar surface 50 of an adjacent chamber or with an electrode 52 connected to the other side of the break so as to form a voltage grading capacitor. The surfaces 50 may be the metal or metallized walls of the chambers 3U or separate plates secured thereto. Each adjacent pair of breaks is associated with one chamber 30 and comprise a bridging contact 63 on an insulating rod 64 movable rectilinearly by pneumatic means controlled by solenoid valves (Figs. 5, 7, 8, not shown) and co-operating with rigid fixed contacts 59, 60 within the high pressure reservoir 20. Each break has an arcing electrode (121) connected to a metal blast chamber 33 common to the two adjacent breaks and connected with the capacitor plates 50 of chamber 30; each blast chamber has a valve 32 exhausting through a pipe 31 into the chamber 30. Each chamber 30 comprises a pair of multi-walled polygonal toroidal tubes 41 having a plurality of staggered vents (Fig. 4, not shown) from which the cooled gases pass into the lower pressure tank 11 (Fig. 1, not shown) surrounding the breaker. The gas is recirculated by a pump (25). The contact structure is assembled on a frame 58 slidable from the tubular reservoir 20 on runners 55; connections to bushing conductors (16, 17) are made by sliding plug-andsocket connectors (66, 68). In a modification (not shown) the cooling chambers 30 are located within the high pressure reservoir allowing the surfaces 50 to be closer together to provide greater capacitance. Additional flat disc electrodes may be placed between the surfaces 50 and connected to the contacts 60 to improve the voltage grading. The spaces between the surfaces 50 may be filled with cast synthetic resin which may contain bubbles of a compressed inert gas of high dielectric strength. The surfaces 50 may alternatively be covered with a skin of P.V.C.

Title: Improvements in or relating to machines for making paper and like bags
Inventor: ALSOP ARTHUR GRAHAM
IPC: B31B23/00
Filed: 1959-06-03
Abstract: 882,222. Forming bag tubes. STRACHAN & HENSHAW Ltd. Sept. 2, 1960 [June 3, 1959], No. 19010/59. Class 94(2). Relates to tube-forming apparatus wherein a web of paper is folded about a former plate to form a tube and is forwarded to a cut-off position and consists in a nip-bar assembly comprising an upper and a lower roller 22, 23 with nip-bars or lands 26, 27 respectively, the roller being angularly adjustable relatively to each other to vary the peripheral lengths of contact of the lands which co-operate with each other to nip the paper tube after it has issued from the former plate. The land extends for substantially the full length of its roller and, in the embodiment shown, subtends an angle of approximately 60 degrees. The peripheral speed of the rollers is less than the travelling speed of the tube as imparted by rollers 14, 15 and when the tube is nipped between the lands a slack 28 is therefore caused in it of an amount governed by the length of contact of the lands, which may be varied between a maximum of 60 degrees of rotation of the rollers 22, 23 and a minimum of the smallest fraction of a degree which will produce practically only a line nip of the tube. A heater bar 20 rotates so that it moves upwards from below the paper tube in a path 21 slightly in advance of the forward edge 17 of the former plate 11 and forces the lower ply 13 against that edge and the upper ply 12 against the edge 19 of a breaker plate 18, both edges being serrated. The tube is then cut with the edges of the plies one in advance of the other, which facilitates the sealing of the end of the tube to form a bag. The slack 28 assists the cutting action and the relative angular adjustment of the rollers 22, 23 allows the correct amount of slack whether the tube is moving slowly, for a long bag, or quickly, for a short bag.

Title: Improvements in mechanism for reciprocating the beds of printing machines
IPC: B41F3/58
Filed: 1946-06-26
Abstract: 613,676. Bed - reciprocating apparatus. FURNIVAL & CO., Ltd., FURNIVAL, F. S., and DAVIS. R. June 26, 1946, No. 19050. [Class 100(ii)] [Also in Group XXIV] A mechanism for driving the reciprocating bed of a printing machine in which the bed has a period of constant speed for the greater part of its travel, comprises a rack on the underside of the bed which is engaged alternately by two gear wheels mounted on separate shafts one behind the other, each wheel being formed with teeth for half its width for substantially half its periphery, and the whole of its width for the remainder of its periphery. Two gear wheels 4 and 5 are mounted on shafts 6 and 7 and are driven in opposite directions by inter-meshing gearing. The wheels 4 and 5 are capable of being moved axially on shafts 6 and 7 to engage a rack 3 on the bed 1 by means of a pivoted lever 10 and a cam 15. When the bed 1 comes to the end of its travel at constant speed it is retarded, reversed and accelerated by a reversing mechanism actuated in known manner by a crank 17 during which period the non- toothed portion of the previously operating gear wheel 4 or 5 is opposed to the rack teeth.

Title: Improvements in or relating to Graphite Moderator Structures for Nuclear Reactors
Inventor: DALE WALTER BERNARD
IPC: G21C5/00
Filed: 1967-04-25
Abstract: 1,191,152. Moderator structures. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 18 March, 1968 [25 April, 1967], No. 19056/67. Heading G6C. Graphite moderator bricks have holes drilled in them at intervals allowing fluid access, at least some of the holes being partially filled by inserts solely of graphite shaped to allow divided peripheral flow in the holes. This arrangement serves to prevent the corrosion-inhibitor, e.g. methane, content of the CO 2  coolant from falling significantly as the coolant diffuses into the moderator. The graphite insert may be a squaresection rod with its corners contacting the wall of the hole. The corners of the rod may be rounded to match the contour of the wall. A generally hexagonal-section insert is also considered suitable. The holes will be at least ¢- inch in diameter since difficulties arise in drilling smaller holes in graphite, and the inserts are necessary to prevent too great a reduction in the moderating effect of the bricks.

Title: Improvements in and relating to driving mechanism for printing and like machines
IPC: B41F13/14
Filed: 1926-08-04
Abstract: 269,381. Marinoni Soc. Anon. April 30, 1926, [Convention date]. Rotary intaglio machines.-A machine for printing from an engraved cylinder, or a like machine, is provided with an adjustable drive for the printing-cylinder which enables the cylinder to print accurately in conjunction with an impression cylinder of constant diameter in spite of the variations of the printing-cylinder due to grinding off the old designs. The printing-cylinders A, Fig. 1, which are made of a steel core coated with copper are made to commence with of a size slightly larger than half the diameter of the impression cylinder D. The cylinder D is driven direct from the main driving-shaft C, and the cylinder A is driven from the shaft C by means of a pair of gears 11, 14, Fig. 4, mounted side by side on an axle 1<b> secured by nuts to a frame 2. The shaft C gears with wheel 11, and the cylinder A with wheel 14, and motion is transferred from wheel 11 to wheel 14 by mechanism which can be set to cause the cylinder A to move while printing either slightly faster or slower than it. would do if the wheels 11, 14 had no relative motion, and during the non-printing rotation of the cylinder A, it is correspondingly moved slower or faster so as to cause the next printing operation to commence in the proper register. The moans for transmitting motion from the wheel 11 to tho wheel 14 comprises a sliding block 10 pivoted to a plate 8 which rotates with the wheel 11 but is moved radially thereon by a fixed cam 4a engaging a roller 6 on the plate 8. The block 10 engages a slot 13<a> in a plate 13 fixed to the wheel 14. The plate 13 is adjustably connected to the wheel 14 by means of bolts 15 engaging curved slots in the plate 13. To adjust the plate 13 the nuts of the bolts are locsened, and by means of a handle 18 guided by a pointer 17 and a fixed scale, the plate is moved about the axis of a circular boss 19 which engages a circular hole in wheel 14. The plate is secured in the adjusted position by tightening the nuts of the bolts, and by this means the slot 13<a> is set so as to be inclined at an angle a, Fig. 3, to the radial position of the slot 13a. This slot inclination is to one side or other of the central radial position according as the diameter of the printing-cylinder. A is greater or less than the pitch circle of its driving-pinion. If this diameter is equal to the diameter of the pitch circle the slot is set so as to be radial and the motion of cylinder A is then uniform. If the printing-cylinder is of greater diameter than the pitch circle the wheel 14 lags relatively to wheel 11 during the printing rotation of cylinder A, but the lag is made up during the non-printing rotation of cylinder A.
