Title: Improvements in structures adapted to be launched into the air, for example, aircraft ejection seats
IPC: B64D25/10
Filed: 1959-10-16
Abstract: 889,699. Aircraft ejection seats and parachute apparatus. MARTIN, J. Sept, 16, 1960 [Oct. 16, 1959], No. 35192/59: Class 4. An aircraft ejection seat includes a drogue parachute connected by a line to an airman's personal parachute, a manually operable cutter for severing the line in an emergency, and means automatically operable on actuation of the cutter to release the locks by which the airman is held to the seat. The invention is applicable to any system in which it may be necessary to cut the line between the drogue parachute and a main body, and at the same time to release a subsidiary body from the main body. Fig. 2 is a side view of a cutter unit attached to the upper part of the ejection seat frame, and Fig. 3 is a section or line III-III of Fig. 2. The line 10 from the drogue parachute which serves to stabilize the ejected seat, and then under normal conditions, to withdraw the user's main parachute after separation of the user from the seat, is received in a shaped slot 9, and is normally retained by a shaped member 22 pivoted to the unit at 24 and held over the mouth of the slot by a spring biased plunger 25 abutting a flange 27 on member 22. A piston 11 is slidable in a bore 7 in the unit, and has a replaceable guillotine blade 12 which works in a slot 13 extending past slot 9 into the head 8 of the unit. Gas under pressure can be admitted to bore 7 through a screwed coupling 14, to sever the line 10. Fig..5 shows the manual control lever 38 and gas generating unit 19, which is mounted on the side of the seat pan 17. The handle 38 is pivoted at 50 to the unit 19 and has an aperture 40 for the user's fingers. A link 39 extends from the handle to a sear 34 passing through a firing pin 35 protruding from unit 19. Movement of the handle to the broken line position withdraws the sear, arming and releasing the firing pin which detonates a cartridge (not. shown) in unit 19 to generate gas under pressure, which passes through a rigid tube 16 and flexible tubing (not shown) to coupling 14, Fig. 3. Unintentional movement of the handle is prevented by a hook 41 pivoted to the handle at 51 and engaging a pin 43 on unit 19. The tail of the hook engages a slot in a spring biased plunger 46, so that the. handle cannot be raised until the end of plunger 46 is depressed by the user's thumb. Equally,. the hook and pin prevent return of the handle to the full line position until plunger 46 is depressed The handle 38 is connected by.a link 47 having telescoping parts 61, 63, to a crank.48 on the shaft 49 which operates the seat harness locks, so that the user is released from the seat whenthe line 10 is cut. The telescoping parts.61, 63, allow shaft 49 to be rotated by a further manual control (not shown) to effect release of the.locks without operating the cutter unit. Specifications 640,520, 711,234, 831,472, 854,768 and. 854,769 are referred to.

Title: Improvements in and relating to locks
IPC: E05B63/04
Filed: 1922-12-28
Abstract: 191,062. K÷nig, J. Dec. 28, 1921, [Convention date]. Lock-mechanism, tumbler type; reversible.-A reversible lock for use on right and left hand doors, of the type having a bolt with key-recesses on its upper and lower edges corresponding to upper and lower keyholes, has an auxiliary tumbler in addition to the locking tumblers, the actuation of which by the key parts the locking tumblers under spring pressure, and also prevents the release of the bolt except by using the kevhole employed in shooting it, one keyhole being on the outside and the other on the inside of the door. The bolt a has symmetrically arranged key-recesses d, d<1> and is guided in a slot in the flange b of the casing and in a pin c. The locking tumblers e and auxiliary tumbler g are pivoted on the pin c. The tumbler g is controlled bv a spring k fixed in the casing at its upper end, and has a pin-and-slot connection with the flanged arm m. The locking tumblers e are controlled by springs f secured to them at one end and to the flange on the arm m at the other end, and have the usual gatings as shown in Fig. 7. The auxiliary tumbler e has a V-shaped gating as shown in Fig. 6. When the key is inserted in keyhole n' and turned, it swings the auxiliary tumbler g upwards, bringing the arm h<1> of its grating into position to allow the travel of the stud o fixed to the bolt. At the same time, the swing of the tumbler g deflects the arm m, as shown in Fig. 3, flexing the springs f to keep the tumblers e up to their work in locking the bolt while shot. Further movement of the key operates the tumblers e and shoots the bolt in the usual way. When the key has completed its locking turn, the bolt is locked by the engaeement of the stump o in recesses in the tumbler gratings due to the action of the flexed springs f, and the tumbler g is held in a deflected position by the retention of the stump o in the arm h' of its gating, rendering unlocking by using the other keyhole n impossible. To unlock, the keyhole n<1> is again used, the turn of the key releasing the tumblers e from the stump and withdrawing the bolt. This restores the stump o to its nosition in the part i of the gating of the auxiliary tumbler g which can then assume its middle position where it is held by its spring k, releasing the tumblers e from spring pressure. The tumblers e do not lock the bolt in its withdrawn position, this being done by the tongue between the arms h, h<1> of the gating in the tumbler g, as shown in Fig. 1. If the keyhole n is used for shooting the bolt, the stud o travels in the arm h of the gating in tumbler g and holds it to prevent unlocking by employing keyhole n'. If desired, the tumbler g may have a gating as shown in Fig. 8, in which case it serves also as a locking tumbler when the bolt is shot.

Filed: 1974-08-12
Abstract: 1479922 Holographic data storage SIEMENS AG 12 Aug 1974 [14 Aug 1973] 35353/74 Heading G2J [Also in Division G4-6] An opto-electronic sequential data storage system is adaptable for mono-dimensional holographic recording or read-out of data and for non- holographic recording or read-out. For holographic recording, coherent light 1 from a laser (not shown), is passed through a modulator 2 receiving the data as input, to produce an object wave OW which passes through a lens 4 and a plane-parallel plate 5, inclined relative to the beam axis of object wave OW about an axis normal to the figure, the focused object wave OW being directed on to a moving storage medium 6. A reference wave RW, 'produced by passing coherent light from the same laser through a beam-splitting prism 10, a lens 9 and a plane-parallel plate 7 inclined relative to the beam axis of reference wave RW about an axis lying in the plane of the figure, is directed on to the same region of the storage medium 6. The plane-parallel plates 5, 7 cause the focused object wave OW and reference wave RW to each assume the configuration of two narrow spaced apart focal lines, the two sets of focal lines being mutually perpendicular. The axes of waves OW and RW are equally inclined to a centre-line normal to the path of movement of the storage medium 6. For holographic read-out, a reproduction wave is provided having the same geometry as the reference wave RW. For non-holographic recording of data, the plane-parallel plates 5, 7 are each brought into a position normal to the respective beam axis. For non-holographic read-out no modulation voltage is applied to the modulator 2, so that an unmodulated laser beam is directed on to the storage medium 6, from which selective reflection produces a modulated read-out wave which passes via the beamsplitting prism 10 to a photo-sensitive detector 12.
