Title: Improvements relating to the fixing of turbine and compressor blades
IPC: F01D5/26
Filed: 1964-10-23
Abstract: 1,080,026. Fixing turbine or compressor blades. SULZER BROS. Ltd. Oct. 23, 1964 [Nov. 1, 1963], No. 43324/64. Heading F1T. A turbine or compressor blade root is formed with outwardly facing surfaces clamped between the faces of two opposed projections which extend perpendicularly to the longitudinal axis of the blade and are formed on removable clamping members, the outwardly facing surfaces converging longitudinally of the blade so that the root is held between the projections by a wedging action, and the widths of the faces of the projections being substantially smaller than the widths of the outwardly facing surfaces, the widths being measured longitudinally of the blade. As shown, a stator blade 1 has a root comprising a wedge-shaped portion 12 and a threaded stud 2. Two clamping members 13, each having a part-cylindrical outside surface, are formed with inclined inner surfaces 15, which extend parallel to the inclined surfaces 12' of the wedge 12, and projections 14 which engage the surfaces 12'. The clamping members 13 are received in a bore 13' of a rectangular blade shoe 4 and secured therein, together with the blade, by a nut 3. The blade angle may be adjusted by temporarily backing-off the nut 3. The shoe 4 is positioned in a groove 5 in a blade support ring 6 by two pegs 7 which engage a groove 8 formed in one side of the groove 5, and is wedged against the other side of the groove 5 by wedges 11. Spacer shims 16 are provided between adjacent blade shoes. Alternative clamping members (not shown), have projections 14 located at different points of their inclined inner surfaces 15 so that the wedge 12 may be clamped at its widest point, its narrowest point, or any point therebetween. The natural frequency of vibration of the blades is thereby adjustable. An assembly for fixing a rotor blade, Fig. 6 (not shown), differs from the assembly shown in Figs. 1 and 2 in that the wedge tapers towards the aerofoil portion of the blade, and the blade is urged radially outwardly so that the inclined surfaces of the wedge abut the projections on the clamping members.

Filed: 1969-09-02
Abstract: 1286098 Error detection KOMBINAT ZENTRONIK VEB 2 Sept 1969 43423/69 Heading G4A A data acquisition or accounting machine has a circuit for preventing deviation between the number of characters set up on the machine keyboard and a machine place capacity pro. grammed by a unit P. The number of digits entered on the keyboard is counted on a 4 stage flip-flop binary counter (M1-M4) operating on modulo 16, the number of digits programmed is entered from the unit P and the two numbers feed comparison circuits V 1 -V 4 . If the digits entered are too numerous the unit ST responds, the machine cycle is not released when a start button is pressed, and the numbers must be entered again after clearing the counter with a correction key. The highest power digit (2<SP>3</SP>) is compared first using the comparator V4 and, if the programme signal A4 and the counter signal A4 are equal, comparison is shifted to the (2<SP>2</SP>) comparator V3 and so on. If they are not equal the AND gate UG5 controls the unit ST. The comparators also check that the number of places coincide using the AND gate UG1.

Abstract: 1,210,271. Baling presses. TEXAS INDUSTRIES Inc. 23 Sept., 1968 [29 Sept., 1967], No. 45191/68. Heading B5F. A side feed pick up hay baler has a bale chamber having compression regions located either side of the plunger so that a bale is formed during reciprocation of the plunger in both directions. In this way the output of the baler is increased. In the embodiment shown in the Figures, a bale chamber 2 obliquely mounted in an adjustable manner upon a wheeled frame is centrally fed with hay picked up by mechanism 79 by a lower feed unit comprising spaced chains 33 between which are slung bars 37 having upstanding teeth 36 and an upper feed unit comprising three orbitally moving sets of tines 45, 53, 73, actuated by known rod controlled crankshaft mechanisms. The plunger 3 is carried between upper and lower slides 4 which are reciprocated between guide rollers 5 by pitmans 8 connected to a slider mounted on one side wall of the chamber 10. The slider itself is reciprocated by a rod 13 eccentrically pivoted at 14 to rotating sprocket wheel 16. In operation, hay is introduced into the chamber by the feed units as the plunger reaches its extreme positions so that upon the return stroke of the plunger the hay is compressed. The bales thus formed are separated and tied and either dropped off the trailing flap 27 or guided off by the leading curved guiding member 24. In a second embodiment (see Figs. 5 and 6, not shown) the chamber is located parallel to the direction of motion of the frame and the plunger carrying slides are reciprocated by pitmans eccentrically connected directly to pinions mounted upon the upper and lower surfaces of the bale chamber.

Abstract: 1381259 Change-Speed gear WILSON MILLER & CO Ltd 23 Dec 1971 [23 Sept 1970 12 Oct 1970] 45222/70 and 48295/70 Heading F2D A four speed and reverse gear C coaxial with a hydrokinetic torque converter B has a first input sleeve 16 mounting a sun 1 and driven from the converter B and a second input shaft 13 driven by the prime mover A through a clutch 15. The drives through first and second clutches 17, 15 connect a drive to the sun 1 and a planet carrier 6 respectively of the gear train C which drives a coaxial output shaft 5 through a ring gear 4 connected to it. A hand brake 10 acts on a drum 9 to hold an attached secondary sun 8 while a hand brake 12 acts on a drum 11 to hold the carrier 6. A uni-directional clutch 21 may be provided between a housing flange 22 and the carrier 6. For first ratio the first clutch 17 is engaged with the carrier 6 held by the clutch 21 or brake 12 to provide a drive from the converter B through a sleeve 18, clutch 17, sleeve 16, sun 1 and inner and outer planets 2, 3, and the ring gear 4 to drive the output shaft 5 in the same direction as the input drive. Second ratio is obtained by applying brake 10 to hold sun 8 to cause carrier 6 to rotate with the sun but at a lower speed to augment the rotation of the ring 4. Third ratio provides a split torque by releasing brake 10 and engaging the second clutch 15 providing a drive through the shaft 13 to the carrier 6 to rotate it at a speed greater than the sun 1 proportional to the degree of slip in the converter which effect is however reduced for given conditions by the proportion of torque diverted to the shaft 13. For fourth ratio clutch 17 is released brake 10 engaged thus freeing the converter output so that the drive is wholly through the shaft 13. Reverse is obtained by engaging a clutch 20 and brake 12 to drive the secondary sun 8 with the carrier 6 held. In modifications the clutch 15 may be placed on the output side of the planet carrier. In Fig. 5 a supplementary epicyclic gear train 44 may be provided with a toothed annulus 45 as an extension of the annulus 4<SP>11</SP> to give lower ratios while in another modification the supplementary gear may be omitted while still using unstepped long pinions.

Title: Absorption refrigeration system
IPC: F25B49/04
Filed: 1965-11-01
Abstract: 1,109,322. Refrigerating. CARRIER CORPORATION. 1 Nov., 1965 [30 April, 1965], No. 46164/65. Heading F4H. In an absorption system having a gas-fired generator 10, separator 20, condenser 11, evaporator 12 and absorber 13, the refrigerant in an evaporator sump 34 is maintained at or below a given level. As illustrated the level is determined by an opening 76 in a partition separating the evaporator from the absorber. Refrigerant overflowing through the opening 76 passes through a line 80 into a pipe 55 which carries solution from a pan 48 surrounding the absorber tube bundle 46. The pipe 55 in turn opens into an outlet 56 from an absorber sump 50. A wall 77 overlies the overflow opening 76. In an alternative embodiment, Fig. 2 (not shown), the partition is imperforate and a line (90) leads directly from the evaporator sump 34 to the pipe 55. The line (90) includes an inverted U-bend (92) the height of which determines the liquid level in the sump 34. The pressure conditions of the system are such that if siphon action occurs in the bend (92) the refrigerant evaporates to prevent further draining. However if the refrigerant is contaminated with absorbent its boiling point is lowered so that siphon action can occur to drain the contaminated refrigerant.
