Title: Improvements in or relating to aircraft arresting gear
IPC: B64F1/02
Filed: 1955-08-15
Abstract: 785,144. Aircraft arresting devices. ACME PRECISION PRODUCTS, Inc. Aug. 15, 1955 [Jan. 13, 1955], No. 23431/55. Class 4. Aircraft arresting gear comprises a pair of supports 8 one each side of a runway, an actuator cable 2 releasably secured at its ends to the supports, an arresting cable 30 lying slack in the runway and releasably secured at its ends to fixed points one each side of the runway, and lifter straps 22 extending between the two cables, whereby when the actuator cable is engaged by a forward part of an aircraft, the arresting cable is flung into the air to engage the aircraft and arrest it. In Fig. 1, the actuator cable 2 is secured to two stanchions 8 through shear pin assemblies 4, shearing at 3,000 lbs. the stanchions being maintained vertical by elastic cords 9. Lifter straps 22 are fastened to the cable 2 and to grommets attached to anchor plates 32 on the runway by devices which separate on a pull of 250 lbs. The arrestor cable 30 is disposed in loops, Fig. 8, formed in the straps 22 by light sewing or snap fasteners as at 24. Each end of the cable 30 is secured to anchor chains 33, Fig. 5, forming drag devices, and is also tied by a cable 78 to a shear pin device 76, shearing at 4,000 lbs., and attached by a cable 74 to the foot of the stanchions 8. Fig. 5 shows the stanchion lying flat on the runway. In operation, the stanchions and actuator strap 2 are raised, and when an aircraft approaches from the right, Fig. 1, the nose wheel engages the cable 2 and taughtens it, breaking the fastening 24 and throwing the cable 30 upwards as shown in Fig. 8 to form an upwardly extending loop in the region of the aircraft which engages the main undercarriage. This loop is part of a tension wave, which propagates along cable 30 and is reflected at each end by the attachment of cable 74 to the stanchion. This reflection ensures that the loop is properly shaped by the time the main undercarriage engages it. Thereafter all shear devices break, and the cable 30 drags the chains 33 to slow the aircraft. In the case of a long cable, intermediate stanchions 40, Fig. 1, are provided, normally maintained upright by elastic cords 64. The actuator cable is attached to a cap 50 on each stanchion, and when the cable 2 is engaged by an aircraft, the cap is raised from the stanchion, this triggering a device releasing the cord 64 so that the stanchion may lie flat on the runway, in case the aircraft should otherwise engage it.

Title: Maintenance of temperature conditions of satellites
Inventor: CROWDER JEFFREY LAURENCE
IPC: B64G1/24
Filed: 1964-06-05
Abstract: 1,106,552. Satellites. BRITISH AIRCRAFT CORPORATION (OPERATING) Ltd. 8 June, 1965 [5 June, 1964], No. 23433/64. Heading B7W. A satellite has a substantially cylindrical body and means for maintaining the axis of the body perpendicular to the ecliptic while the satellite is in orbit, the cylindrical surface of the body being well insulated thermally so that substantially no radiant heat from the sun reaches the interior of the satellite, and the ends of the body also being thermally insulated, but less well, this insulation of the ends being adjustable by means responsive to temperature within the body. The body is formed as a twelve-sided prism with a trough 4 having a wall 30 extending from the outer wall 28 of the body to accommodate a telescope 6 pivotally mounted on axis 8 by a horseshoe-shaped member 9 formed with a sleeve 14 to carry a starlock unit 16 which is rotatable about its axis 20, the member 9 being secured to a bulkhead 22. The ends of wall 28 are closed by walls 24, 26, the wall 24 being recessed within the body to shield it from radiation from the sun. In order that equipment within the body may be maintained at an optimum temperature, the wall 28 is well insulated, this being the wall which in orbit faces the sun, and the end walls 24, 26 are less well insulated. The internal temperature is controlled by allowing heat generated by equipment within the body to escape, and for this purpose wall 24 is formed with two radiation openings (36 (Fig. 3, not shown) closed by pivotable shutters (38), each coupled by a pinion to an axially-movable rack-bar which is made responsive to temperature-responsive elements (44), (44a) within the body.

Title: Improved cargo sling
IPC: B66C1/12
Filed: 1939-08-15
Abstract: 533,584. Slings. HAYES, T. Aug. 15, 1939, No. 23517. [Class 78 (iv)] In slings of the type in which a flexible member passing round the load and forming a noose is engaged slidably with a second flexible suspension member, the two flexible members are connected so that they cannot become detached when in use. In one form the sling comprises a noose member 5 (Fig. 2) passing under the load and having an eye 7 at each end through which the second member 3 slides. The latter is connected to a triangular support 1 which can be tilted by hauling on the rope 14 and slackening the rope 13, to release the link 9 from the hook 2 to dump the load. The eye 6, which cannot pass either of the eyes 7, prevents detachment of the two members. Fig. 6 shows a modification in which eye 7 of the noose member 5 is connected directly to the part 3 of the other member, while the pull-chain 4 passes from the eye 7 through the other eye 8.

Title: Means for automatic signal systems for traction vehicles
IPC: B61L3/12
Filed: 1947-09-03
Abstract: 652,874. Track apparatus for actuating signals on trains and controlling trains. SOC. TECHNIQUE POUR L'INDUSTRIE NOUVELLE SOC. ANON. STIN. Sept. 3, 1947, No. 24272. Convention date, Sept. 17, 1942. [Class 105] Cab signalling or train control is effected by means of two or more track magnets 1 (one of which is a permanent magnet) vertically arranged so as to present only one pole, the flux of each of which directly and briefly actuates, on the train, an armature 5 of a receiver relay which armature is returned to its normal unoperated position by an auxiliary magnet 2, the flux of which acts on a part so disposed as to be unaffected by the track flux, such receiver relay or relays acting on an electromechanical device controlled by at least two current circuits. Fig. 3a shows track permanent and electromagnets 1, 2 acting simultaneously on two train-carried receiver relays 3. The receiver relay armatures E1, E2, Fig. 3b, control a relay A fed at a mid-point and having a front contact Al in the circuit to a brake magnet B. One half winding of the relay A receives current over armature E2 in its unoperated position and this is sufficient to close the front contact A1. When passing the signalling point the armature E2 is operated by the track permanent magnet 1 to open the circuit to the particular half winding but if the other armature E1 is operated by the track electromagnet 2 it energizes the other half winding so that the front contact Al remains closed. Should armature E2 fail to respond then the two half windings would be fed at the mid-point and so neutralize each other whereupon the relay A would open its front contact A1 to give a braking. The Specification as open to inspection under Sect. 91 comprises also an arrangement shown in Figs. 4a (Cancelled), and 4b (Cancelled), wherein track permanent and electromagnets 1, 2 act successively on a single train-carried receiver relay 3. The first operation of the armature E drops a stick relay A which opens its contact A3 to de-energize the brake magnet C a back contact C1 of which prepares a circtut to a relay B which is energized on the immediately following operation of armature E and at its contact B1 prepares a pick-up circuit for the relay A, this thereafter being energized and held by its stick contact Al when the armature E resumes its unoperated position. The brake magnet is thus only briefly deenergized at a clear signal. At a danger signal the electromagnet is not energized so that the relay A remains dropped and a sustained braking ensues. This subject-matter does not appear in the Specification as accepted.
