Title: Projectile fuze
IPC: F42C15/22
Filed: 1965-03-26
Abstract: 1,078,700. Projectile fuzes. OERLIKONBUHRIE HOLDING A.G. March 26, 1965 [March 31, 1964], No. 13029/65. Heading F3A. A percussion fuze for spin - stabilized projectiles is provided with self-destruction means comprising a lever 18 pivoted on a pin 17. One arm of the lever extends through a slot in a sleeve 19 and bears against a thimble 10 and hence on a striker spring 9 and the other arm 18a bears against a plastically deformable element 15 held in a radial bore 13 of a sleeve 3 by a ring 14. Before launching the projectile, the end 7a of a hammer sleeve 7 bears against a rotor 5 as in Specification 740,643 to maintain a primer 6 out of alignment with the firing pin 8. The sleeve 7 is held by the sleeve 19, which in turn is immobilized by a sleeve 24 abutting a disc 25. The disc 25 is secured by a layer 26 of fuzible material as in Specification 888,579 over which a cap 27 is screwed. Movement of the lever is prevented by a sleeve 20 supported by a deformable body 21. On launching the sleeve 20 sets back due to inertia and upsets the body 21, thus freeing the lever 18. The disc 24, due to heating of the fuze tip, fuzes and releases the sleeve 19 thereby freeing the rotor, which rotates until the primer 6 is aligned with the pin 8. Centrifugal force swings the lever 18 which upsets the element 15 and stresses the destruction spring 9. If impact does not occur within a given time, due to decreasing centrifugal force, the balls 11 move inwards and release the hammer sleeve 7. The spring 9 then drives the sleeve rearwards and the pin 8 fires the primer. In a modification, the hammer sleeve is supported as in Specification 740,643 and two centrifugal levers are provided to bring about self-destruction. The two levers are immobilized by latching bolts which set back on firing against plastically deformable bodies to unlatch the levers. The elements 15 may be conical or hollow cylinders made of pure aluminium.

Variable speed toothed gearing. - A variablespeed and reversing gear for motor-vehicles &c. comprises a circular plate 2 driven by bevel gearing from the driving shaft 1. engaging a sphere 5 connected to the driven shaft 6. The plate has a number of circular rows of projections 9, 10, 11 adapted to gear with depressions in the sphere arranged in great circles passing through two poles 8, the sphere being rolled over the face of the plate to vary the speed. The sphere rotates with a sleeve 7 on the shaft 6, but is enabled to roll by the provision of slots 20. In the neutral position, a central projection on the plate fits into a hole in the sphere. If rolled beyond this position, a reverse drive is obtained. The sleeve 7 is moved along the shaft by a fork 22 and sector 25. To ensure that it can only be moved when the axis 8 of the sphere is horizontal, a rod 26 connected to an eccentric strap 37 engages a number of recesses 27, one for each speed, and is withdrawn by the eccentric once in each revolution, when the axis 8 is horizontal. The sleeve 7 may be disconnected from the shaft 6 by swing- ing a pivoted key 28 into a slot 31 by a fork 35, and the sphere is then moved into the neutral position by a spring 36. The gearing may be rendered continuously variable by providing friction surfaces on the plate and sphere between the rows of teeth.

Title: Improvements in feeler mechanism for weft replenishing looms
IPC: D03D51/34
Filed: 1921-05-13
Abstract: 182,992. British Northrop Loom Co., Ltd., (Northrop Loom Co.). May 13, 1921. Weft-feeler arrangements. - In weft-feeler mechanism for initiating weft replenishment and of the type comprising an impinging member 21, which is moved forwards at the beat-up by the weft in the shuttle, and a detecting-member 25, which normally penetrates the weft and moves forwards with the member 21 without moving relatively thereto, but engages the hard surface of a depleted bobbin and is thereby moved relatively to the member 21 thus rocking a finger 28 against the action of a spring-controlled vertical pin 30 and initiating weft-replenishment, the detecting- member is locked against such relative movement until it has reached a predetermined position of proximity to the path of travel of the shuttle by means of a spring-controlled slotted plate 35. This plate normally holds up the pin 30 and finger 28, thereby preventing relative movement of the detecting-member until an adjustable lay-bunter 40 engages and moves the plate, so as to move the slot thereon beneath the pin 30, thereby freeing the pin, the finger 28, and the detecting- member, whidh, for the remaining part of the beat-up can act in the usual manner. Premature or accidental operation of the feeler mechanism is thereby prevented. The finger 28 is pivoted at 29 to the impinging member 21, and, when it is rocked by the movement of the detecting-member 25 relatively to the member 21, its notched end engages and operates the controller 6 of the weftreplenishing mechanism.
