Abstract: 1,109,478. Aircraft ejection seats. SAAB AKTIEBOLAG. 9 Dec., 1965 [12 Dec., 1964], No. 52266/65. Heading B7G. An aircraft ejection seat gun has an outer tube 5 fixed to the seat, and an inner tube 6 connected to the aircraft structure through a crash damper 4 contained within a third tube 9 to which the inner tube is fastened by shear pins 17. The crash damper, the subject of Specification 1,104,894, comprises a tool 14 arranged to cut a plate 18, the tool being connected to a perforated bulkhead 11 welded to the inner tube 6 by a push-rod 13 slidable through an end wall 10 of the third tube 9.

Title: Air cooling of turbine blades
IPC: F01D5/30
Filed: 1973-11-12
Abstract: 1424925 Turbine rotor blades - cooling system A V C D CORP 12 Nov 1973 [1 Dec 1972] 52400/73 Headings F1G and FIT The invention relates to a method of supplying cooling air to turbine rotor blades in which air is directed into a chamber adjacent the turbine rotor disc with such a velocity that the tangential component thereof is equal to the peripheral speed of the rotor disc in that region. The engine shown comprises a turbine rotor disc 16 having blades 12 mounted at the periphery thereof by means of blade roots 18 engaged in axially directed slots, the blades being retained by a circular member 20 of the downstream side and a circular member 22 at the upstream side, the member being secured to the rotor disc by means of bolts 24 extending through lugs 28 formed on the member and through openings formed in the rotor disc. The member 22 is spaced from the rotor disc 16 to define space 72 through which cooling air flows radially outwardly from an inlet 29 extending between the lugs 28 to passages 74 formed in the blade roots and thence to passages 76 formed in the blades from which it discharges into the turbine working fluid. The turbine rotor shaft 30 is supported in a bearing 32 mounted in a bearing support 34 supported by stator structure 38, 40. Cooling air taken from the engine compressor passes through duct 62, through a passage 66 in the bearing support 34 to a series of small chambers 68 defined by a seal assembly 52, 54, the air discharging from the chambers 68 through openings defined by vanes 69 into a further chamber 60 from which the air passes through the inlet 29 to the annular space 72. The vanes 69 are inclined at such an angle that the air issues with a velocity A the tangential component V t  of which is equal to the peripheral velocity Vd of the rotor disc at that radius.

Abstract: 1410660 Hauling devices MILBRAS 15 Dec 1972 [15 Dec 1971] 57955/72 Heading B8B [Also in Division F2] A grip for a free cable winch comprises an inner jaw 17 adapted to move between the arms of a U-shaped outer jaw 18, the two jaws 17, 18 defining together a passageway for receiving a cable 9 and being capped at opposite ends by brackets 23, 24, each of which has a transverse portion 37 to which is secured a push eccentric 40 bearing on the back of the inner jaw 17, and each bracket 23, 24 being pivotable about a transverse pin 21, 22 which is also located behind the back of the inner jaw 17 at a location which is off-set with respect to the eccentric 40. The free ends of the arms of the bracket 23 extend beyond the outer jaw 18 and are connected, on the one hand, to a stop 35 on the outer jaw 18 by a spring 31 which biases the bracket 23 in the direction in which the jaws 17, 18 are clamped and, on the other hand, to the free ends of the arms of the bracket 24 through pivoted connection links 56. An arm 54 welded to the back of the bracket 24 is provided with a hole 55 for receiving the pivot pin of a connecting rod by means of which the bracket 24 is connected to a hoist-control lever (2) (Figs. 1 and 2, not shown). Each eccentric 40 is connected to the back of the inner jaw 17 through a bidirectional connection formed by pivoting the eccentric 40 in a housing surrounding the eccentric over more than 180 degrees. The connection is obtained in practice by securing a small block 45 to the back of the inner jaw after mounting the eccentric 40 in a semi-cylindrical recess in the back of the jaw. The block 45 has a curved bearing surface which closes on the eccentric 40 and thus completes the housing for the eccentric. Two tenons on the bases of two blocks 45 fit transversely and in back to back relation in a dovetailed slot in the jaw 17, a screw passing through two opposing halfnotches in the blocks and engaging a hole tapped in the jaw. Each eccentric 40 is provided at its top with a boss 39 which is nested into a corresponding opening in the transverse portion 37 and welded thereto. In order to grip the cable, the control lever is actuated to transmit to the pin in the hole 55 a force in the direction of arrow 58, causing the brackets 23, 24 to swing in the same direction and the eccentrics 40 to bear upon the back of the inner jaw 17 in the direction of arrow 59.
