Title: Improvements in and relating to machines for making and portioning pills and tabletsand the like
IPC: B30B15/32
Filed: 1938-09-19
Abstract: 519,319. Moulding tablets &c. by rotary table machines. HANSEN, M. Sept. 19, 1938, No. 27309. Convention date, Sept. 20, 1937. [Class 87 (ii)] A machine for making and portioning tablets, pills, &c. comprises a press in which the tablets are formed from pulverulent material, means for moving each tablet immediately to a preliminary reservoir, and means acting in synchronism with the latter means whereby the reservoir is emptied at predetermined intervals. The tablets are moulded by pistons 3, 5 carried by rotating tables 2, 4, and reciprocated by cam surfaces 7, 7b. A spoked wheel 10 rotated in synchronism with tables 2, 4, by the engagement of pins 13 with a spoked wheel 12, serves to direct the moulded tablets into a channel 14 where they are held until, on the complete revolution of the moulding table, contacts-41, 42 are closed to energize a relay 19 which lifts a stop gate 16 and allows the tablets to fall into a reservoir 24 held beneath the channel 23 by another energized relay. Upon de-energization of the latter relay, the reservoir 24, which is mounted .as a pendulum, swings into position beneath a tube 27 and a current of air passing through perforations at the base and created by a vacuum at 30 serves to draw the tablets upwards against a grating 29 where they are agitated to remove rough edges &c. When next the contacts 41, 42 are closed the reservoir 24 again moves beneath the channel 23 and the vacuum is destroyed by the lifting of a flap 3,1 whereupon the finished tablets fall into a suitable receptacle. An additional cleaning device comprising a perforated rotatable drum 150, and Fig. 3, having a helical wall running through it may be located in the channel 23.

Title: Improvements relating to projectile fuses having axially movable strikers
IPC: F42C9/16
Filed: 1954-09-22
Abstract: 752,991. Projectile fuzes. AKTIEBOLAGET BOFORS. Sept. 22, 1954 [Sept. 25, 1953], No. 27401/54. Class 9(1) Relates to a projectile fuze having an axially movable striker to actuate a primer carried by a slide movable transversely of the striker between a safety position and the armed position, the slide being held in the safety position by an axially movable slide having rack teeth co-operating with a speed-limiting device. According to the invention, the speedlimiting device engages a third slide having rack teeth and adapted to operate a lever to actuate the striker, the second and third slides being engaged with the device for simultaneous movement to the armed position, whereupon the second slide is disengaged from the device and the third slide moves to operate the lever. The housing 1. Fig. 1, has two longitudinal bores in which are arranged slides 3, 4 carrying respectively racks, 5, 6, the racks being connected to a speedlimiting device 7-18, Fig. 2. The pinion 7 meshing with rack 5 carries a gear 9 in mesh with a gear 11 on a shaft 12 carrying' an escapement wheel 13. The wheel 13 cooperates with a pawl 14 pivoted on a pin 15. Pinion 7 also meshes with a gear 10 on a pinion 8 in mesh with the rack 6, which bears against a spring 19. Above the primer-containing slide 21, the spring-held striker 24 is mounted in a sleeve 28 and extends through a collar 26 which engages a two-armed lever 30. A pin 31 limits the upward movement of the slide 3, which extends through the housing of slide 21 to hold slide 21 in the safety position. On firing the projectile, the rack 5 sets back and through the escapement mechanism 7-8 moves the rack 6 rearawrdly the movement being delayed by the pawl 14. When the slide 3 reaches its rearmost position, it frees the transverse slide 21 which is then moved by its spring 22 until the primer 23 is aligned with the striker, the fuze then being armed for 'direct action. In this position, the pinion 7 escapes from the rack teeth of the slide 3 breaking the connection through the gear train 7-18 to the rack 6. The spring 19, stressed during rearward movement of the slide 4, drives the slide 4 upwardly, the movement again being controlled by the escapement wheel 13 and pawl 14. At the end of its upward movement, the slide 4 actuates the lever 30 to bring the striker against the primer and thus forms a self-destruction device. Specification 684,721 is referred to.
