Title: Improvements in or relating to a process and an arrangement for braking or retardingrotary air motors
IPC: F01B17/00
Filed: 1963-06-28
Abstract: 1,046,943. Air motor brakes. REDERI SOYA A.B. June 28, 1963 [July 6, 1962], No. 25870/63. Heading F2E. [Also in Division F1] In a process for braking or reducing the number of revolutions of rotating air motors provided with an inlet and outlet for the driving air, the outlet side is throttled by means of a variable throttle actuable by variation of the inlet pressure of the driving air in such a manner that the motor is caused to work as a compressor. As shown the motor comprises balls 14 reciprocally mounted in radial cylinders 12 of a block 10 which is rotatably mounted on a fixed shaft 9. Compressed air entering the motor at 47 and passing along passage 17 in the shaft 9 communicates with one of the apertures 15 to act on a ball 14 when the opening 13 of the respective cylinder overlays the aperture 15. The ball presses on the carrier periphery of a cup shaped member 6 which is mounted on an output shaft 1 eccentrically with respect to the shaft 9 so that both members 6 and 10 are caused to rotate. When the cylinder 12 communicates with the other aperture 15 it is exhausted via passage 18 to allow the ball to move to its radial inner position. The outlet pressure of the motor acts via a hole 26 on a diaphragm 22 mounted on a sleeve 24, which is biased by a spring 27 and acts to regulate the inlet pressure according to the outlet pressure by means of ports 29, 30. This acts to automatically stabilize the air supply to the motor. The outlet of the motor is throttled by a spring-loaded disc 33 which co-operates with the end 35 of an adjustably mounted cylinder 36 in which is slidably mounted a piston 37. The latter is pressed by the inlet pressure through-holes 46a towards the disc 33 and acts thereon to adjust the opening between the. end 35 and the disc 33. The air from the motor passes through this opening and then along the screw-shaped passage 44 to the atmosphere. The opening is thereby automatically adjusted according to the inlet pressure and acts to automatically regulate the number of revolutions of the motor through the actuation of the working pressure for the diaphragm 22. If the inlet pressure is disconnected the disc 33 will be pressed against the end 35 to close the outlet and cause the motor to work as a compressor. In another embodiment the inlet pressure is regulated by the outlet pressure prior to acting on a piston regulating the outlet opening.

Fig. 1 shows an arrangement in which two sources A, B, disposed one on each side of the correct track P Q, emit beams which rotate in opposite direction and are synchronized so that they intersect on the track P Q as indicated at 02, 03. In order to indicate a second course p<1> Q<1> for aircraft travelling in the opposite direction, there is provided a third source B<1>, the sources B, B<1> being blocked by screens on the sides Q, Q<1> respectively.

Title: Improvements in projectile fuzes

IPC: F42C15/30
Filed: 1955-09-16
Abstract: 789,761. Ammunition fuzes. SOC. TECHNIQUE DE RECHERCHES INDUSTRIELLES -ET MECANIQUES. Sept. 16, 1955, No. 26649/55. Class 9(1) A base fuze for a rifle grenade which is armed by the propellent gases has a body 1- in which a bolt 2 is secured by shear pins 3 to prevent the escape from a sleeve 4 of -a ball 6 latching a striker 5. On launching the grenade, the propellant. gases pass through the tail S and act on a piston 2 extending from the bolt 2. The pins 3 shear and the bolt moves forwards until it abuts a cushion 4<SP>1</SP>, e.g. of lead, stressing a spring 9 as it moves. The gases prevent the return of the bolt 2, until the grenade leaves the rifle when the spring 9 thrusts the bolt against the end 10 of the tail tube. The ball 6 then escapes freeing the striker and arming the fuze for actuation on impact, when the striker moves forward due to inertia to strike a detonator 8. When the grenade is to be discharged by a cartrige fitted with a wad or dummy bullet, the piston 2 has a domed head to reduce the possibility of jamming or deformation of the piston by solid debris from the cartridge. To further protect the piston, filtering orifices for the gases may be provided at the forward end of the tail tube. The fuze may also be mounted in a selfpropelled projectile between the motor and the war-head as in Fig. 5. The base a of the fuze forms the front closure of the motor and supports a partition c which guides the piston 2'. Filter orifices 11 for the gases communicate with a chamber 12, which in turn communicates with the piston chamber 13 through a hole 114, to assist the filtering action. Additional filtering means may be provided comprising a cushion 15 of thin copper, within the motor, a second cushion 16 before the opening 114 and an annular baffle 17 in the chamber 12. A further expansion chamber 18 may be formed in the piston 2'. In Fig. 6 the bolt 27 with integral piston 27<SP>1</SP> is held by a circlip 29 against a ring 24 secured by shear pins 25. Within the bolt is a safety ring, 30 held against the ring 24 by a ball 31 and by a circlip 32 surrounding the striker sleeve 20. On discharge of the grenade, the gases push the bolt 27 against ring 24, the pins 25 shear, and the ring 24 moves towards a washer 34, preferably of lead, and the ball 31 escapes into an annular space 34<SP>1</SP>. As the projectile decelerates, spring 33 pushes the ring 30 forwards and the ball 22 frees the striker. The ring 30 may be replaced by a ring locked by balls housed in the pistoncarrying bolt, which bolt is itself secured by shear pins as in Fig. 2. In a modification of Fig. 5, the chamber 13 has an annular inwardly projecting flange surrounding the piston with small clearance for the piston. A layer of fusible material, such as paraffin wax or tallow, is also placed over the axial passage leading from the propellent chamber to the piston, to prevent unburnt matter entering the fuze and to provide a lubricant for the fuze passages.

An apparatus for attaching handles B, connected by neck portions C, to a strip S of material, such as the ticking of a mattress, comprises a guide 33 for feeding the handles to an attaching station, a pair of dies 28, 8, and 29, 9 mounted respectively, on supports 32, 17 movable by means of a ram 14, 16 towards each other in order to attach the handle to the sheet and cutters 39, 44 mounted on the lower support 17 for severing the neck portions C between the foremost handle and the next succeeding handle during such movement. The upper support 32 is connected to the piston 16 of the ram and is guided by spindles 21, 22 slidable in lugs 13 on the ram cylinder 14. The lower support 17 is loaded away from the upper support by springs 26. In operation, the connected handles fall under gravity through the guide 33 so that the foremost handle abuts a stop 34 and its ends rest on movable supports 36, 37. Backing plates 12 for the pronged fasteners already located in the handle are fed into the dies 8, 9 by means fully described in Specification 932,785.
