Title: Improvements in or relating to aircraft ejection seats
IPC: B60R22/46
Filed: 1963-03-20
Abstract: 1,012,355. Remotely controlled fastenings. J. MARTIN. Feb. 7, 1964 [March 20, 1963], No. 10973/63. Heading E2A. [Also in Divisions A3, B4 and B7] An aircraft ejection seat is fitted with a mechanism for drawing the occupant's head against a headrest on initiation of ejection and includes a line 5 wound round a reel 4 fixed to a rotatable tube 1 biased by a torsion spring 10 to wind in the line. The tube is normally held against rotation, in one embodiment (Fig. 3) by a square peg 24 engaging a corresponding opening in an end plate 14 of the tube 1. On initation of ejection fluid pressure, e.g. from a cartridge is applied to a piston 22 fixed to the peg, thus moving the peg inwardly and allowing the tube to rotate and draw in the line 5. In another embodiment (Figs. 6 and 8) a ratchet wheel 60 is fixed to the tube 1 and a pawl 62 is held against the wheel preventing rotation in either direction by a piston 64. The piston is moved by fluid pressure to allow the pawl to reciprocate in the bore 66 and the ratchet wheel and tube to rotate in the direction winding in the line 5. The mechanism also includes a spindle 43 (Figs. 1 and 6) on which parachute pack harness straps inserted in a cavity 44 are held. During ejection gas from a charge 35 propels a knife 31 to cut the line 5, and then passes through a bore 40 to act on a piston 42 fixed to the spindle to withdraw it from the cavity 44. A plunger 48 co-operates with a piston 46 to prevent the spindle returning into the cavity. The spindle may be manually withdrawn by a ring 49.

Title: A buckle for flexible elements
Inventor: CARLMARK ROLF
IPC: A44B11/06
Filed: 1969-02-28
Abstract: 1,248,688. Buckles. R. CARLMARK. 28 Feb., 1969 [1 March, 1968], No. 10996/69. Heading E2A. A buckle comprises a stirrup-like member 10 co-operating with a loop member 30, the stirrup like member consisting of a substantially U-shaped portion 12 and a transverse bridge piece 22 connecting limbs 14', 14# of the substantially U-shaped portion and lying substantially parallel with a cross piece 15 of the substantially U-shaped portion, the end portions of the limbs providing two outstanding extensions 16 terminating in lugs 18, 18# which are disposed in co-axial relationship with each other and extend away from one another and parallel to the bridge piece, the loop member loosely embracing the stirrup-like member between the bridge piece and the lugs and being adapted to pivotally engage the lugs by means of two side pieces 34', 34# and also to slide relative to the lugs to thereby reduce the space between a first cross piece 32 of the loop member and the bridge piece, the sliding and pivoting motion serving to clamp a first flexible element between the first cross piece and the bridge piece, the loop member also having means by which a second flexible element can be connected to it for moving the loop member to the clamping position. In the construction shown the bridge piece is provided with a sloping surface 22 which faces the lugs and the end portions of the bridge piece extend beyond the limbs 14 and co-operate with the lugs to hold the loop member in engagement with the stirrup-like member. In a modification, Fig. 5, the bridge piece does not extend beyond the limbs 16 and instead a bar 28 is welded to the limbs, the bar 28 having its end portions extending beyond the limbs and serving to hold the loop member in position in conjunction with the lugs. In a further modification the bridge piece instead of having two inclined surfaces as shown consists of a flat plate and the limbs of the stirrup like member are bent so that the plate is inclined. The loop member shown can be modified by providing it with an arched member welded to its cross bar 32 for receiving a short thin strap which enables the loop member to be moved. It can also be modified by providing it with a finger piece for aiding movement. A modification is also described in which the loop member is provided with a third cross member so that a slot is defined in which the second flexible element is received. The buckle shown is intended for use with flexible elements in the form of straps but in a modification the flexible elements can be ropes in which case the bridge piece and the cross piece 32 of the loop member are transversely curved so as to engage a larger area of the rope. The loop member is also provided with a U-shaped portion attached to its cross piece 36 that which defines an opening for receiving the second rope. In this construction the loop member is retained in position on the stirrup-like member by means of the lugs and by plugs which have shanks secured in the limbs of the stirrup-like member.

Abstract: 1,171,353. Detecting surface flaws photoelectrically. SOC. NOUVELLE DE ROULEMENTS. March 8, 1967 [March 11, 1966], No. 11010/67. Heading G1A. A ball to be inspected for surface defects is held in contact with an optical scanning head by means of a cylinder 1, Fig. 2, which is rotated in the direction F1 and reciprocated in the directions F2 and F3. The optical head comprises a total reflection tube 4 which directs light from a lamp, Fig. 1 (not shown) on to the ball and light reflected therefrom is received by a photo-electric cell 6. If there is a flaw in the surface of the ball 8 the output of cell 6 is reduced and this reduction in output may be used to operate known sorting means for the balls. The cylinder 1 may be covered by a flexible material having a high coefficient of friction with the balls.

An antislip device for a railway vehicle compressed air brake comprises a double-seated valve 2 having a valve member 6 connected to a piston 11 which separates a first chamber 13, of a cylinder 12, communicating with a deceleration detector 18 from a second chamber 14 in communication with the first chamber through a throttling constriction 21, the piston being connected to part of a telescopic valve 23 for exhausting the second chamber 14 and the length of stroke of the valve 23 being less than the length of stroke of the member 6 of the valve 2. The valve 2 is connected to a compressed air pipe 3 and an exhaust pipe 9 and controls the brake cylinder 5. In operation, so long as the deceleration detector 18 does not respond, normal braking occurs but if a predetermined rate of deceleration is exceeded the detector 18 exhausts chamber 13 through a pipe 17 to atmosphere and piston 11 moves upwards to exhaust cylinder 5 through pipes 4, 9, chamber 14 being also exhausted through the constricted outlet as valve element 25 is lifted by the piston.

Abstract: 1,184,349. Automatic control of aircraft. SOC. DE FABRICATION D'INSTRUMENTS DE MESURE. March 9, 1967 [March 9, 1966], No. 11200/67. Heading G3R. R. Transition of an aircraft from normal flight to hovering is effected by switching an automatic pilot so that the aircraft is decelerated by a change of pitch altitude which is maintained constant with altitude until, at predetermined low speed, deceleration and altitude are reduced with speed until the hovering condition is achieved. In the arrangement described, pitch altitude of an aircraft is normally maintained constant by a pitch altitude detector associated with a servosystem automatically controlling pitch altitude. When switches are operated to initiate transition, a signal from a Doppler speed detector is progressively applied to the pitch servosystem through a limiter so that deceleration results and is maintained constant with the aid of an accelerometer. When the signal from the speed detector falls below a value determined by the limiter, pitch altitude, and hence deceleration, decreases with speed until a hovering condition is achieved. When transition is initiated, a signal from a radio altimeter is also applied without shock to a servosystem controlling altitude so that the latter is maintained constant when speed is above the limiting value, but is progressively reduced, when speed is below the limiting value, until the hovering condition is achieved.

Abstract: An electrical resistance material comprises a mixture of boron nitride with one or more conductors of the first order, such as powdered metals, carbon or graphite, to which may be added badly conducting oxides, silicates, or carbides.  A resistance is formed by mixing the materials together with a binder, such as coal tar or pitch, into a plastic mass which after moulding into shape is brought to a temperature of 300 DEG  C. and is then strongly heated in an oven from which air is excluded.  The resistance is preferably embedded in graphite or powdered carbon during the heating process.
