Title: Improvements in or relating to gas-turbine engines
Inventor: MATTINSON DONALD HAMILTON
IPC: F02C7/32
Filed: 1950-10-16
Abstract: 703,262. Gas turbine plant. ROLLS-ROYCE, Ltd. Oct. 5, 1951 [Oct. 16, 1950; March 16, 1951], Nos. 25207/50 and 6435/51. Class 110 (3). [Also, in Groups XXIV and XXVII] In a compound gas turbine plant having high and low pressure compressors independently driven by separate turbines, an auxiliary drive shaft is connected to the high and low pressure rotors through a free wheel drive mechanism which is arranged so that, in starting, a drive from the starter motor can be taken through the auxiliary drive shaft to the high pressure rotor only and that, during normal running, a drive shaft from the low pressure rotor only. In the arrangement shown, Fig. 1, of the first Provisional Specification, the low pressure compressor 12 is driven by a low pressure turbine through a shaft 10 nested within a shaft 11 by means of which the high pressure compressor 15 is driven by a lugh pressure turbine. To start the engine, the high pressure rotor shaft 11 is rotated by a motor 17 through a clutch 21, spur wheels 18, 19, shaft 20, bevel wheels 23, 24 shaft 25, ramps 27a of element 27, rollers 34, inner element 28 and spur wheels 29, 30. During normal running, the low pressure rotor shaft 10 drives the engine auxiliary gear box 22 through spur wheels 32, 33, inner element 31, rollers 35, ramps 27b, outer element 27, shaft 25, bevel wheels 24 and 23 and drive shaft 20. The ratios of the gear elements 32, 33 and 29, 30 are so chosen that in normal running of the engine, the gear element 29 and thus the driven member of the free wheel device between the shaft 25 and the high pressure rotor 11 rotates faster than the gear element 32 and thus faster than the drive shaft 25 so that no drive is transmitted through the ramps 27a and rollers 34. The clutch 21 may comprise a number of centrifugally loaded pawls in a free wheel device permitting the spur wheel 18 to over-run the starter motor 17 when the engine is running normally. In a modification, the drive to the high pressure rotor'is taken through a sleeve rotatably mounted on bearings supported on projections from the adjacent ends of the low pressure and high pressure compressors. In this arrangement, the free wheel device between the auxiliary drive shaft and the high pressure rotor is mounted inside one end of the sleeve 53, Fig: 2, of the second Provisional Specification. The driven member of the free wheel device carries a number of spring loaded pawls 56 which engage ratchet teeth 53b on the sleeve. The pawls are so arranged that when the high pressure rotor rotates above a selected rotational speed they are withdrawn from the ratchet teeth by the action of centrifugal force on counterbalance weights 56b formed on the pawl tails. The other end of the sleeve is provided with teeth which mesh with the teeth of a gear wheel carried by the auxiliary drive shaft. This gear wheel is shaped so that the inner surface of the toothed rim may form the driven member of a free-wheel device connecting the low pressure rotor to the auxiliary drive shaft.

Title: Method and apparatus for collecting rod-like articles
Inventor: RUDSZINAT WILLY
IPC: A24C5/352
Filed: 1961-07-12
Abstract: 949,993. Packaging cigarettes &c. K. KÍRBER. July 11, 1962 [July 12, 1961], No. 25227/61. Headings B8A and B8C. [Also in Divisions B7 and F2] In a machine for delivering rod shaped articles into trays an empty tray S is removed from a track B and carried along path FB (Fig. 2) by the combination of a conveyer chain 5 and guides 17 18 (Fig. 5) to be hung on a support rail 19 pivoted at its ends in bars 340 and is then lifted by support arms 20 21 which are mounted on a slide 265 driven by a lever 281 on a stub shaft 293. The tray is then moved along path Q by these arms. At the same time rocker teeth 23 move a full tray off a carrier 22 which then rises under the action of weights 31. When an empty tray is placed by the arms 20 21 on carrier 22 it falls slowly along path N and is intermittently retarded by a brake BV in synchronism with the filling operation which is carried out by placing one row of articles in the tray at a time. The arm 22 falls continuously after the filling operation is completed. When the carrier reaches the bottom of its stroke and a full tray is removed arms 20, 21 collect an empty tray and place it on the arm 22 when it has risen to the top again. A cover SD which is fixed to the tray and held in position by means of an electromagnet as the tray descends is allowed to fall when the tray reaches the bottom of path N, the delivery device A (not shown) having placed the last row of articles in the first tray immediately prior to placing the first row of cigarettes in the next tray. The full tray is removed by rocker teeth 23 between guides 23, which teeth reciprocate in a horizontal direction, and the tray then moves upwards along path H by rocker teeth 25, which reciprocate in a vertical direction, assisted by pivotally supported retaining teeth 27. The tray being guided by the action of its support rails 15 on bars 340. A catch 16 on the tray causes a pawl 147 to engage in a moving chain 5 which carries the tray along path FB and back to the track B. The track B is then moved forward to a position where the next empty tray is ready for removal. The height of bar 3 is adjustable by means of an extendable plate 1 fixed to a base 2 of the machine. The sheet metal container comprises a body portion open at one end and a cover portion with flanges extending over parts of the front and rear walls of said body portion and being slidable in the direction of said walls. Lugs are provided on the ends of said flanges to locate in grooves on said walls to guide the cover in its movement over the body portion.
