IPC: F02C7/36
Filed: 1970-10-08
Abstract: 1278570 Toothed gearing GENERAL MOTORS CORP 8 Oct 1970 [13 Oct 1969] 47894/70 Heading F2Q [Also in Division F1] The invention relates to a gas turbine ducted fan engine in which the fan is driven from a turbine-compressor shaft of the engine through reduction gearing which includes two gear sets having equal speed counter-rotating output gears. A plurality of radial shafts extend across the gas flow duct, pinion gears on each radial shaft engaging with both output gears, a further pinion at the radially outer end of each shaft engaging with a ring gear mounted externally of the gas flow duct rotating with and driving the fan. The engine shown comprises LP compressor 12, HP compressor 20, combustion equipment 29, HP turbine 23 and LP turbine 15, the HP turbine driving the HP compressor through shaft 22, and the LP turbine driving the LP compressor through shaft 14, the LP turbine also driving the ducted fan 34, 35 through reduction gearing 18 disposed between LP and HP compressors. Two gears 52, 55 are splined to the LP shaft 14, the gear 52 engaging intermediate gears 68 which are rotatably mounted on stub shafts 71 of a fixed member 72; the intermediate gears 68 engage an internal ring gear 67 on a wheel 76, the wheel also having bevel gear 87 with which engage bevel pinions 83 mounted on the radially inner ends of radial shafts 82 which extend across air flow duct of the engine between the LP and HP compressors 12, 20. The shafts 82 are supported in fixed structure by means of bearings 88, 92, the shafts carrying at their radially outer ends gear pinions 84, the pinions engaging a face ring gear 48 which is rotatably mounted in bearing 46 and is secured by spline connection 50 to the hub 34. The fan blades 35 are supported on the hub 34. The second gear 55 which is secured on the shaft 14 engages pinions 62 which are rotatably mounted on a planet carrier 60 by means of bearings 66, the pinions also engaging a fixed ring gear 58. The planet carrier 60 is rotatably supported in a bearing 79 on the gearwheel -76. The planet carrier 60 is also formed with a bevel gear 86 with which also engage the bevel pinions 83 mounted on the radial shafts 82.

Title: Refrigerating machine
IPC: F25B9/14

Abstract: 1,108,899. Refrigerating. CHICAGO BRIDGE & IRON CO. 25 Oct., 1966 [23 Feb., 1966], No. 47915/66. Heading F4H. A cold gas refrigerator comprises a cylinder 64 and a piston 72 which are relatively movable in non-simple harmonic manner and a regenerator 90 which is within the cylinder and which is also movable -in non-simple harmonic manner. As illustrated the piston 72 is fixed and the cylinder 64 is movable. Gas is introduced to and exhausted from the cylinder chamber 79 via gas passages 77 and 78, a three-way valve 82 and a port 84. The three-way valve is appropriately adjusted during a cycle by a rack 86 moved through control lines 88. The regenerator 90 comprises alternating layers of copper screen 94 and glass cloth 95 located between slotted plates 91 and 92 and includes a coil 96 for the abstraction of cold from the refrigerator. Conduits 97 and 98 serve to circulate fluid through the coil 96 and their upper parts are surrounded by rigid plastics sheaths 102 which are a sliding fit in the top of the piston and are connected to a bar 108. An actuating cylinder 122 moves the regenerator through the bar 108 at constant velocity. A flexible seal 69 is connected between the piston and cylinder. and the latter is connected to actuators 121 which serve to restrain movement of the cylinder when compressed gas is admitted to the latter and allow it to move upwardly with constant velocity and which also serve to move the cylinder downwardly with constant velocity during an exhaust stroke. Energy stored by the actuators during the initial restraint may be used to reduce the energy requirements of the apparatus. The cycle is as follows. Starting from the Fig. 7 position, compressed gas is admitted through the passage 78 to raise the cylinder 64, the regenerator being simultaneously raised by the actuator 122 to the Fig. 6 position. The regenerator is then lowered until it is adjacent the top of the piston. Valve 82 is actuated to close the passage 78 and open the passage 77 thereupon gas under pressure in the chamber 79 exhausts through the passage 77. The cylinder is then lowered to expel residual gas. A second cylinder and piston may be arranged in opposition to the first above a plate 66, the two cylinders being integral and thereby moving together.

A separator for removing solid or liquid particles from a gas stream comprises rows 2, 3, 4 of vertical baffle plates 1, plates in adjacent rows being staggered as shown and making obtuse angles. The respective leading and trailing edges of plates in adjacent rows may end on, overlap or end short of a common plane 5, and the leading edges of one row may be half way between the trailing edges of the upstream row. Leading edge portions may be curved as shown, both leading and trailing portions may be bent to one side of the plate or plates may be flat. Plates may comprise ridges or vanes to form particle traps. Plates may be galvanised sheet steel, plastics or glazed or unglazed ceramics and may be coated with rubber or plastics for protection against acids or abrasion. For dust collection, plates may be wetted by running water and arranged vertically over a drain tray (Fig. 5, not shown). The angles between plates in adjacent rows may be 120‹ 140‹, and the angle may decrease from one pair of rows to the next downstream. The angles of the plates in each row may be adjustable, manually or automatically, and this feature is used in an arrangement in which water mist from a mist producer is fed through a separator whose plates are automatically adjusted to maintain a predetermined humidity in the outgoing air. The baffles in the last row may be oriented normal to the planes between the rows, and the parts of the emerging streams in which particles are concentrated may be piped off and discharged to waste or treated to recover the particles. A row of plates may be formed as one unit to facilitate building up separators of several units in series and parallel.

[Also in Division A4] A vehicle safety seat arrangement comprises curved arms 21, 22 mounted, at waist level of a seat occupant, fixedly and movably respectively on the seat back, or a rigid frame asociated therewith, and a further body restraint member such as at least one curved arm 23 extending from the seat back over the occupant's shoulder. The fixed arm is preferably nearer the centre line of the vehicle and movement of the outer arm 22 is linked to the opening and closing of the vehicle door. A vertical shaft 24 on which the arm 22 is mounted is connected by a rack and pinion (32), (33), Figs. 4 and 5 (not shown), to a bar 31 linked to a lever 28 which can be turned about the door hinge axis by means of a bracket 29 secured to the door. Movement of the arm 23 may be coupled to movement of the arm 22 by means such as bevel gearing 27 between the shaft 24 and a shaft 25, pivotably mounted in brackets 26, on which the arms 23 are mounted. To allow the arms 22 and 23 to be moved to the out-of-use position when the door is closed and to allow forward and rearward movement of the seat when the door is open the pinion (33) may be disengaged from the rack (32) by depression of the shaft 24 against the action of a spring (34). If the seat back is inclined the teeth of the rack and pinion may be correspondingly inclined. Alternatively when the seat back is also angularly adjustable the connecting bar 31 may be telescopic to accommodate forward and rear movement of the seat and have at its rear end a longitudinally extending rack meshing with a pinion which also engages a transversely extending rack having teeth curved so that the pinion at the lower end of the side shaft moves angularly about the curved teeth while remaining in mesh with them when the angle of the seat back is adjusted. The arms may be progressively more resilient towards their free ends and may be padded. There may be releasable latch means to hold the movable arms in their out-of-use positions. In a simpler embodiment (Figs. 1-3, not shown) a hinged arm (3) weakly spring- biased to out-of-use position is connectible to a fixed arm (2) by quick release means (12)-(14) and a strap (15) preferably stiffened adjacent its mounting on the seat back is adjustably secured to the arms, preferably to the fixed arm near its free end.
