Abstract: 1,229,454. Buckles. BRITAX (LONDON) Ltd. 24 March, 1969 [4 April, 1968], No.5812/ 68. Heading E2A. A safety belt buckle comprises a housing 1, a latch 6 movably mounted in the housing, a tongue 2 insertable into the housing for engagement by the latch, spring means 9 biassing the latch into its tongue engaging position, whereby when the tongue is inserted into the housing, it is automatically engaged by the latch, and latch release means 16 carried by the tongue to move the latch into a position of the disengagement with the tongue. In the construction shown the housing 1 has a base plate 3 with upstanding integral side walls 4 both of which are inturned and downturned over a portion of their length adjacent the end of the housing into which the tongue enters to provide channels into which lugs 19, 19' of the tongue enter so that the tongue can only be disposed in the housing in one orientation. Near the rear end the base plate has an aperture 5 for engagement by a belt length. The latch 6 is spaced above the base plate 3 so that the tongue 2 can be accommodated between the latch and the base plate and for this purpose the latch is provided with feet 7 which bear against the base plate 3 and which also act as fulcrums for pivotal movement of the latch plate; the latch is also provided with pressed out portions which provide latching surfaces 8 and which in the latching condition enter an aperture 10 in the tongue and engage an edge 11. The spring means 9 is secured to the latch and engages the underface of a cover plate which extends across the top of the housing between the side walls 4 to bias the latch to the latching position. The release means is a lever 15 pivotally mounted on the tongue 2 with one arm 16 inclined upwardly and away from the tongue and the other arm 17 terminating in a foot 18 which projects into the aperture 10. Suitable spring means (not shown) are provided to bias the lever 15 into the position shown. When the tongue is inserted into the housing the foot 18 is disposed underneath the latch so that pivoting the lever 15 pivots the latch away from the base 3 so that the surfaces 8 become disengaged from the edge 11 of the aperture 10. The lugs 19, 19' can be omitted if desired.

Abstract: 1,231,676. Positive clutches. GARRETT CORP. 16 Sept., 1969 [10 Oct., 1968], No. 45678/69. Heading F2C. A positive clutch in a safety decoupler shaft, e.g. between a gas turbine engine and a starting motor, comprises teeth (16), Fig. 2 (not shown), shaped on one side 16A to transmit drive from one splined shaft part 14 to another part 15 on relative rotation in one direction, and shaped on their other side (18), (19) to move the parts axially apart against the resistance of a torsionally prestressed torsion bar 20 to permanently disengage the clutch on relative rotation in the opposite direction. The bar 20 has a slot 22 at one end through which passes two pins 23, 23A attached to part 14. The other end of the bar has an hexagonal head 21 engaging in a corresponding bore in part 15. The rod is axially split to provide torsion portions and engages freely within a sleeve 24 brazed to part 14 with a free groove 25 underlying a groove 27 in part 14 at which the part shears if the engine binds. If overload occurs in the reverse direction, the faces (18), (19) or the teeth urge the parts 14, 15 apart against the resistance of the torsion bar until the head 21 leaves its corresponding bore in part 15, when the parts separate freely and are retained disengaged by a split ring 30 abutting the end of sleeve 24 until the clutch is manually re-engaged. To re-engage the clutch, the pin 23A is withdrawn and bar 20 moved so that head 21 enters its bore in part 15. The parts 14, 15 are then relatively turned and moved together to allow teeth (16) to intermesh and prestress the bar 20 to urge surfaces 16A together for drive. Pin 23A is then replaced. The teeth 16A are slightly inclined relative to the axis to urge the parts 14, 15 axially together.

Abstract: 1,251,165. Energizing electromagnetic actuators. INTERNATIONAL BUSINESS MACHINES CORP. 30 June, 1970, No. 31525/70. Heading H3T. [Also in Divisions G5 and H1] Rebound of an electro-magnetic actuator is reduced by detecting the rebound and applying to the operating coil a pulse in a direction to oppose the rebound. Fig. 3 shows a centretapped operating coil 13 energized by transistors T5 and T7 in one direction or the other according to the polarity of a signal applied at 29, 30. Concurrently with a change of this signal a pulse is applied at 31 which operates a monostable circuit SS1 to pulse transistor T1 or the corresponding transistor T6 to provide additional current during the early part of the changeover period to speed of the movement. A detector circuit 38, T7 (one for each end of the coil) detects the pulse (T3, Fig. 2 not shown) in the unenergized side of the coil due to the rebound. This, via an AND gate 35 and a monostable circuit SS2, momentarily applies an additional pulse to the transistor T1 or T6 connected to the energized end of the winding to oppose the rebound. A delay 37 and a latch 36 prevents incorrect operation. The invention is applied to the mechanism for arresting the traversing drive for a magnetic disc store. The drive is effected by a lead screw and is arrested by pawls 2 mounted on spring arms 4. They are moved out of engagement with the ratchet by a member 9, 18 carrying a coil 12 located in an annular gap in a fixed magnet 10, 11. Resilient stops 22, 23 absorb some of the energy of movement to reduce the rebound. It is stated that the coil could be stationary and a magnetic former could operate the device. In addition a single coil could be used.

An elevating screw 14 lifts the articles into a scrubber peeler mechanism 16 Fig. 3, having a cylindrical array of peeling rolls, each roll including resilient fingers projecting radially therefrom. The articles then pass through a washer unit 17 and into a sulphite tank 18 to prevent discoloration. Infrared treatment unit. Fig. 7 (not shown). Articles are introduced into the unit by a shuffle feed conveyer whose last shuffle member (22) is arranged and so timed as to drop a row of articles into the valley between two rolls 37, wherein they are carried beneath infrared units (46) and simultaneously rotated by the rolls which roll along tracks (41). The shuffle feed is driven by a motor and gear mechanism (31) via a chain (29) and eccentrics (23 and 24). The rolls (37) are cleaned by a wire brush roll 51, Fig. 1. Scrubber-peeler mechanism. The peeler 16, Fig. 3, comprises a cylindrical array of peeling rolls 71, each having resilient fingers (77), Fig. 4 (not shown) mounted thereon. The individual rolls rotate in the opposite direction to the array as a whole while the articles are drawn through the centre by a feed screw 73. The impact of the rolls removes the surface layer defective portions and eyes which have been softened by the lye solution and infrared treatment from the articles and the recovery of the fingers together with centrifugal effects projects the debris on to the inside of a slowly rotating outer cylindrical housing 61. A cleaning mechanism in the form of a conveyer with resilient blades 84 attached thereto scrapes the debris from the bottom of the housing 61.

Abstract: 1296378 Turbomachine blades; gas turbine plant GENERAL MOTORS CORP 5 June 1969 28611/69 Heading F1G, FIT A high temperature turbomachine includes a row of fluid directing airfoil members exposed during operation to hot motive fluid, each airfoil member being hollow to define an internal cavity which is divided by walls extending spanwise of the cavity into three passages, one adjacent each of the leading and trailing edges with an intermediate passage, means for distributing a coolant fluid into the leading edge and intermediate passages at one end of the airfoil member, means connecting these passages to the trailing edge passage at the other end of the airfoil member, and means to provide an outlet for the coolant fluid at said one end of the airfoil member. In the turbojet engine shown in Fig.3, cold liquefied fuel is supplied by fuel supply pipes (not shown) to an annular manifold 26 from which it flows through passages 51, 52 in the turbine nozzle vanes 13 in one direction and in a passage 53 in the opposite direction. The passages 51, 52, 53 are formed in each hollow vane 13 by webs 47, 49 extending spanwise of the vane, the web 47 being adjacent the leading edge and the web 49 approximately at the mid-chord of the vane. The heated fuel then passes to fuel outlet pipes (not shown). Circulation of cooling fuel to the turbine rotor 14 is effected through struts 18 which extend across the exhaust duct, each strut 18 being of doublewalled construction and the fuel flowing through the space 55 between the walls to one or more fuel pipes and then to a manifold (not shown) on the turbine axis. From the manifold, the fuel flows radially outwardly between the forward face of the turbine wheel 64 and a shroud 105 to enter the space between the outer diameter of the wheel and the turbine blade platforms through discharge holes (not shown). The fuel in this space flows through metering orifices 123 or 125 into passages 121 or 126 in the turbine blades 63. These passages, formed by walls 119, 127 extending spanwise of the blades 63, connect at their radially outer ends with a third passage 129 through which the fuel flows, the fuel then flowing radially inwardly between the rear face of the turbine wheel 64 and a shroud 94 to pass via the central passages of the struts 18 to the fuel outlet pipes. The fuel is supplied by suitable pumping means which puts it under sufficient pressure for circulation. The fuel, which may be vaporized in cooling the engine, is supplied by the fuel outlet pipes to the combustion apparatus of the engine.

Abstract: 1307844 Needling loom NEEDLE INDUSTRIES Ltd 18 May 1970 [23 May 1969] 26359/ 69 Heading D1R A needling loom varies the advancement imparted to the web between successive penetrations of the needle array. Where the web is advanced discontinuously this is preferably accomplished by stepwise variation of the length of a rod 10, 14, connecting eccentric 11, mounted on the crankshaft which drives the oscillating needle array, and the oscillatory arm of a pawl and ratchet or other one-way clutch which drives the take up roller. The two parts 10, 14 are connected by hinge 15. Member 18, rigid with 10, mounts cam 19, which is rotated intermittently by pawl 22 and ratchet 23 in the direction of 26. Pawl 25 prevents opposite rotation. Pawl 22 is moved by rod 24, pivotally connected to eccentric 11 at a smaller distance from axis 3 than rod 10. Hence rotation of the eccentric moves cam 19 and follower 28, which is fast with 14, thus varying the angle between rods 10 and 14, and so varying the effective length of the composite rod. Alternatively the two rods may be arranged for translatory movement (Fig. 2, not shown). Their relative movement may be effected by a pawl and ratchet mechanism. For continuous variation of the effective length, one rod may be connected to the piston rod 31, Fig. 3, and the other to cylinder 30. Pipes 38, 39, connect the two sides of piston 31 to the two sides of piston 43 in master hydraulic cylinder 37. Reciprocation of piston 43 by crank 40 causes a simple harmonic variation in the effective length of the transmission rod. Alternatively the crank is replaced by a driving cylinder (144, Fig. 4, not shown) whose piston (154) is linked to piston (143) by rod (153). Hydraulic fluid pumped by (145) through pipe (146) moves the two pistons steadily to the left, until actuating element (152) on rod (153) closes valve (148). The motion is then reversed until valve (149) is closed. A symmetrical saw-toothed variation in the effective length of the connecting rod results. The above embodiments may also be used in machines in which the web take-up roll is rotated continuously. Preferably however, the variation in the rate at which it is driven is continuously varied by connecting it to planet gears (53, Fig. 5, not shown) which mesh with sun gear (52), mounted on steadily rotating shaft (51), and toothed annulus (56), which is oscillated backwards and forwards by eccentric (59).

Ambient air from inlet 4 is fed by the compressor 5 to inlet manifold 2a and exhaust gas leaving exhaust manifold 2b passes through the turbine 6 to outlet 8. A heat exchanger 26 may heat the air charge from the compressor or may warm air supplied to an air-pressurization and air conditioning system which is supplied with fresh air by a blower 25. The by-pass 12 leads from inlet line 3 through a valve 19 and combustion chamber 13 to exhaust line 7. An injection nozzle 14 is fed from a turbine-driven pump 15 through a valve 16 controlled electrically from a start-control unit 11 e.g. in response to a speed signal from the turbine. An ignition device 17 is controlled from the start control unit 11 which is also arranged to limit the temperature of the combustion gas and the turbine speed. A combined motor/ generator unit 18 acts as a motor to drive the turbo-compressor unit during starting and, when driven by the turbine, supplies current to the battery 10. During cranking the start control unit energizes the solenoid valve 34 into the broken line position in which exhaust line 7 is vented to atmosphere and isolated from the turbine and duct 12. During normal running the valve 19 isolates lines 3 and 7 from each other. In place of the electrical starting of turbocompressor 5, 6 a flow of air to drive turbine 6 may be derived from a reservoir 31 which is charged during a previous running period. In another embodiment the combustion chamber (23), Fig. 2 (not shown) is arranged to be traversed by the flow of exhaust gases from the engine.
