Abstract: 1,008,472. Delivering measured quantities of dough &c. BAKER PERKINS Ltd. May 29, 1964, No. 19242/63. Heading B5A. A machine for delivering measured quantities of dough or meat filling comprises a metering chamber and means for filling this chamber which is responsive to the pressure in the chamber. As shown, material in a hopper 1 is fed by a feed roll 2 through a pressure chamber 3 and into a metering chamber 12c in a dividing cylinder 4. Rotation of the feed roll 2 is effected through a rack 15 and gearing 16, 17, 18 by a fluid pressure cylinder 13. The rack 15 is moved downwardly to drive the feed roll 2 when high pressure fluid is supplied to the upper end of cylinder 13. Return motion of the rack 15 is effected by low pressure fluid constantly supplied to the lower end of cylinder 13, but a clutch (not shown) prevents reverse rotation of the roll 2. When the pressure in the metering chamber 12c reaches a predetermined value, pressure in the upper end of cylinder 13 rises and a switch (not shown) is actuated to rotate the dividing cylinder 4 through 90 degrees. A pneumatically operated piston 11c then expels the material from the chamber 12c. The cylinder 4 has five such chambers, as seen in Fig. 1 (not shown). Upper and lower scraper blades 6, 7 are biased towards the feed roll 2 by a spring 10 and prevent escape of material from the hopper 1 and pressure chamber 3. Specification 1,006,112 is referred to.

Abstract: 729,396. Radar. BENDIX AVIATION CORPORATION. July 13, 1953 [Aug. 27, 1952], No. 19404/53. Class 40 (7). The invention comprises means for generating a bearing marker brightening pulse for application to a cathode-ray tube indicator having a plan-position or B type display in a radar system. Only one complete range sweep is brightened by the arrangement in which the trigger pulses of the radar are applied through a buffer valve 4 to a multivibrator 2, 3 having two stable states. Angle marker trigger pulses 22 are fed through buffer valve 6 from generator 17 when the radar aerial system 7 is in a predetermined angular position and these trigger the multivibrator from one state to the other. The trigger pulse 20 next following the pulse 22 triggers the multivibrator back to its first state and the output from the anode of valve 3 is a negativegoing pulse 23 commencing at the instant of generation of a pulse 22 and terminating at the following trigger pulse. Pulse 23 is differentiated by components 9 and 10 and the positivegoing peak 24 corresponding in time to its trailing edge passed by valve 8 to trigger monostable multivibrator 11, 12, the time constant of the circuits elements 15, 16 of which is adjusted to cause the output pulse 26 to have a duration equal to that of one range sweep. Pulse 26 commences at the beginning of the time base next after the trigger pulse 22 and is used to brighten up a single sweep on the indicator tube to mark the predetermined direction.

Title: Improvements in gas turbine engines
Inventor: JENKINSON JOHN
IPC: F02C7/14
Filed: 1965-05-10
Abstract: 1,095,129. Bearings. BRISTOL SIDDELEY ENGINES Ltd. May 9, 1966 [May 10, 1965], No. 19652/65. Heading F2A. [Also in Division F1] In a gas turbine engine which comprises air compressors in flow series, there being at least one shaft bearing in a chamber between the compressors and at least one mechanical seal which requires to be pressurized by air, at least one zone which requires to receive a flow of coolant air, and bleed-off ducting for conveying air compressed by the high pressure compressor to the seal and to the zone, a heat exchanger is incorporated in the ducting for cooling the air before it reaches the seal and the zone. The invention is described with reference to a gas turbine jet engine designed for operation at Mach 2 in which air tapped from the compressor would be too hot for the pressurizing and cooling purposes. The engine is of the two-spool type comprising low-pressure compressor 35, highpressure compressor 37, combustion equipment 40, high-pressure turbine 39, and low-pressure turbine 34, the H.P. turbine driving the H.P. compressor through shaft 38, and the L.P. turbine driving the L.P. compressor through shaft 36. The L.P. shaft 36 is mounted in a bearing 42 and the H.P. shaft 38 is mounted at its forward end in twin bearings 62, the bearings being supported by stationary structure comprising inner easing 41, vanes 43 and outer casing 20. Air is tapped from between stages 51, 61 of the H.P. compressor and passes through duct 28 to the heat exchanger 22 where it is cooled by flow of boundary layer ram air in duct 15, Fig. 1, not shown. The cooled air then passes through ducting 23 to the space 52 within the inner casing 41, some air then passing to space 54, through passage 55 and bores in the shaft 38 to the space 56 between the two shafts 36, 38 where it serves to cool the shafts which are disposed adjacent the combustion equipment 40. The air finally discharges through seal 50 into the space between the two turbines 39, 34. The seal 50 is provided to prevent the back-flow of turbine gases. The space 56 is defined at its forward end by a tube member 66 adjacent the L.P. shaft 36. Lubricating oil is supplied to the bearings 42, 62 and discharges therefrom through annular scavenge chamber 46. Seals are provided at i, c and f, Fig. 4, to prevent leakage of oil from the bearings, the seals being pressurized by air. Further labyrinth seals are provided at g, h, a, b, e, d. The seals c and f are pressurized by air from the chamber 54 which leaks through the seals b, d, e, the air passing back to the chamber 53 and thence being discharged to atmosphere through duct 69. The seal i is pressurized by air from the chamber 52 which leaks through seal h, this air also passing back to chamber 53 and thence to atmosphere.

Filed: 1955-07-07
Abstract: 782,312. Copy-milling; copy-turning; copyplaning; cutting by spark-erosion. SICOMATIC AKT.-GES. July 7, 1955 [July 9, 1954], No. 19699/55. Classes 83 (3) and 83 (4). [Also in Group XXIII] A milling, turning, shaping or spark-erosion machine for profiling three-dimensionally curved workpieces 7 from drawings 20, comprises means 4, 5 for mounting a work-holder 6, 8 for horizontal and vertical movement relatively to the tool 23, a flexible tape 28 connecting the work-holder to a shaft 31 upon which the tape may be wound, a bar 44 carrying a follower 63 the bar and shaft being connected by a second tape 34 to reciprocate the bar laterally, a third tape 54 connecting a second shaft 56 to a slide 51 moving the tool 23 in a direction at right-angles to the horizontal movement of the work-holder, and a fourth tape 59 connecting second shaft 56 to said bar 44 to move the bar longitudinally. The drawing 20 is mounted on a table 19 rotated by a hand wheel 26 which through jointed shafts 16, 14 also rotates the chuck 6. The chuck-slide 5 moves horizontally on a vertically-movable slide 3 and has attached thereto a bracket 9 carrying a rod 11. A slider 27 to which the tape 28 is attached may be free to slide, or be fixed, on the rod 11. When the slider 27 is free, the horizontal movements of the workpiece accord with the movements of the follower 63 around the drawing 20 representing a transverse section of the work. Rotation of a controlling handle 49 causes rotation of a pulley 33 to take up the tape 34 and pull a block 46 along a fixed rod 47. The block 46 slidably carries the rod 44. The rod 44 slides at 45 on a rod 42, carried on two members 41 sliding on fixed rods 39. The rotation of the pulley 33 and thus the shaft 31 also takes up the tape 28 to move the chuck laterally in a ratio determined by the diameters of the pulley 33 and the shaft 31. Thus, lateral movement of the follower is reflected in lateral movement of the chuck if the slider 27 is free on its rod 11. If, however, the slider is fixed to the rod 11 and the chuck locked, the chuck moves up and down as the follower moves laterally, the drawing 20 then being of a vertical section. The in-and-out movement of the follower is conveyed to the tool 23 via the rod 44, sliding members 41, a rod 43, the tape 59, pulleys 58 and 55 (again in a desired ratio of reproduction), the tape 54 and the tool slide. The in-and-out movement may be performed by an automatic or hand feed of the tool in the direction P3.
