Title: Improvements relating to ejectable aircraft seats
Inventor: LOBELLE MARCEL JULES ODILON
IPC: B64D25/06
Filed: 1951-09-07
Abstract: 707,915. Ejector seats and parachute release mechanism for aircraft. AVIATION CO., Ltd., M. L. Nov. 7, 1952 [Sept. 7, 1951], No. 21179/51. Class 4 An ejectable aircraft seat fitted with harness for an airman has a time delay mechanism arranged to operate the harness release and set in motion by means of a static line which in use is attached to the aircraft. A static line 15, comprising the inner element of a flexible cable, is attached at one end to the aircraft 16 and the outer casing of the cable is secured to the seat by a fitting 18, which carries a bell mouthed projection 19 sealed by a lightly secured cover 20 through which the cable 15 passes, the cable being restrained from outward movement relative to the cover by a nipple 22. The other end of the cable 15 carries a priming pin 25 which, in the position shown in figure 2, restrains a pivoted lever 28 from clockwise rotation under the action of a spring box 31. The free end of the lever 28 is in contact with a plunger 27, to which it is wired for re-setting movements, the plunger forming the driving element of a clockwork mechanism 26. When the seat is ejected the connections for the cover 20 are broken and the pin 25 is withdrawn to free the lever 28, which is urged in a clockwise direction by the spring box 31. When the mechanism 26 has allowed a predetermined movement of the lever 28 the box 31 becomes disengaged from a tail 32 on the lever 28 and extends fully to draw a cable 36 wound on a drum 38 which, when rotated, releases the pilot's harness. A further static line 50, secured at one end to the seat carries at its other end a flexible priming pin 52 which, when withdrawn, frees a lever 55 for clockwise pivotal movement under the action of a spring box 58, lever 60 and time-delay mechanism 63 similar to those described previously. When the box 58 extends fully it acts on a nipple 65 on a cable 66 to pull the rip-cord of the pilot's parachute. The release mechanism may be manually operated.

Abstract: 512,592. High-tension switches; switchgear structures. NIJLAND, H. A. H. July 18, 1938, No. 21308. [Class 38 (v)] A circuit-breaker has its contact make-andbreak element, comprising fixed contacts and co-operating movable contact, accommodated in a fixed metal tank which is provided with fixed lead-in conductors passing through insulators in the wall thereof and is adapted to be filled with an insulating fluid, such as mineral oil, or to contain a gas, and the make-and-break element is connected to the lead-in conductors in such manner that it can be entirely withdrawn from and inserted into the tank while those conductors are alive, and is surrounded by an insulating casing which completely isolates the space in which the switching operation is carried out from the compartment which those conductors enter. The make-and-break element comprises the fixed contact 10 and movable-rod contact 26 mounted in the insulating tube 7, which is closed at the bottom by a plate 8 carrying the contact 10 and a socket 11 for engaging the pluglike end of the bus-bar lead-in conductor 3. Rod 26 slides in a contact 14 which is secured to the cover 6 by insulators 15, 16 and connected by conductor 18 to a socket 19, which engages the cable lead-in conductor 4 and is carried by the closure-plate of an insulator 21 also secured to the cover 6. Conductor 18 is surrounded by an insulating tube 22 passing through a metal funnel 9 mounted on the tube 7, and the parts 7, 9, 21, 22, are filled with mineral oil 23 which also fills the metal tank 1 as shown at 5, but the two oil-bodies 5, 23 are separated. The two bodies of fluid need not be of the same composition or of a liquid character, but if the body 5 is a liquid, its incompressibility may reinforce the tube 7, for which purpose the partition 24, with small vents.25, may be provided below the liquid-level.

Title: Improvements in or relating to starting apparatus for internal combustion engines
IPC: F02N99/00
Filed: 1935-07-29
Abstract: 450,432. Turning-gear. BOSCH AKT.- GES., R., 4, Militarstrasse, Stuttgart, Germany. July 29, 1935, No. 21441. Convention date, July 30, 1934. [Class 7 (v)] In an engine starter in which a friction disc clutch 12, 13, tightened automatically by a pressure nut 7, is interposed between the starter shaft 1 and a pinion 10 longitudinally displaceable at will into mesh with the engine fly-wheel 17, a torsion spring 8 normally moves the nut 7 away from the friction discs. In order to cause the nut 7 to tighten the clutch when the pinion 10 is fully in mesh with the fly-wheel 17, the action of the spring 8 is overcome by a torque transmitted through the friction discs under the control of an auxiliary pressure member 20 dependent on the position of the pinion. As shown, the starter shaft 1 is driven through planetary gearing 4 from a fly-wheel 5 driven by an electric motor, the planet wheels 4 being carried by a drum 2 mounted on the shaft 1. The pressure nut 7 is threaded at 6 on the shaft 1, and the outer member 9 of the disc clutch carries a metal casing 18 having a flange 21 normally bearing against a ring 22 on the casing 3. With the parts in the position shown, the starter fly-wheel 5 is set in rotation and drives the shaft 1, but the disc clutch is inoperative and the member 9 is held at rest by the engagement between the flange 21 and ring 22. On moving the pinion 10 towards the engine fly-wheel, the flange 21 leaves the ring 22 and the cup 9 and pinion 10 are driven slowly from the drum 2 through a spring- pressed pin 23 bearing on the casing 18. When the pinion is fully in mesh with the engine fly-wheel, the disc clutch is brought into action by the pressure disc 20 carried by the casing 18, and is then tightened automatically by the nut 7.

The cross member 12, attached to a V- or U-shaped frame 11, is partially rotated by a link 17 and crank arm 16 from the transporting position, Fig. 1, to the loading on unloading position, Fig. 2, or vice versa. The wheels 14, 15 may, as shown in Figs. 1 and 2, face outwardly or as shown in Fig. 3, be attached to extensions 21, 22 and face inwardly. The wheels 14, 15 may be freely rotatable or driven by means of an engine through shafts parallel with the extensions 21, 22. The wheels of the transported vehicle may be supported on platforms 62, Fig. 7, attached by arms 61 to the mountings 56 of the saucer. shaped wheels 57. A fork 63 pivotally mounted at 64 on the mounting 56 may engage a strut 59 carrying the vehicle wheel 58 to hold the wheel 58 in position on the platform 62. A platform 46 may be provided for the front wheel 47 of the tricycle undercarriage of an aircraft. A strut 49 joining the members 41 of the transporter may be downwardly bowed and removable to permit the passage of the wheel 47 or the like between the members 41.

An electromechanical filter having a doublehump band-pass characteristic comprises one or more H-shaped resonators made of metal or of a dielectric material such as glass, the limbs 2 of the resonator each carrying an electroded layer 3 of piezo-electric or electrostrictive material forming a transducer. A higher order filter may be realized using integral structure comprising three or more plates 2 alternating with bridge-pieces 1. The structure may be pressed from sheet metal. In an alternative construction, a number of resonators of the kind shown in Fig. 3 are bonded together in the manner shown in Fig. 9. In an alternative manner of building up the filter shown in Fig. 16, the bridge pieces are arranged at a small angle to the plates and a zig-zag structure is formed. The filter is supported between foam-rubber blocks 9. Combinations of H-shaped resonators having different temperature characteristics may be used to realize a system which is independent of temperature. The Specification describes valve and transistor input and output circuits in which the capacitances of the transducers are connected in parallel with inductive reactances to provide coupling circuits antiresonant at the centre frequency of the filter.
