Title: Improvements in or relating to devices for setting up cellular cartons
IPC: B31B5/76
Filed: 1934-04-06
Abstract: 418,113. Packeting eggs in cartons. SELF-LOCKING CARTON CO., 589, East Illinois Street, Chicago, U.S.A.-(Assignees of Burger, M.) April 6, 1934, No. 10507. Convention date, May 29, 1933. [Class 94 (i).] A device 30 for use in setting up collapsed egg cartons comprises two rows of blocks 31 for engaging the cross-partitions separated by a longitudinal groove 32. The collapsed carton is formed by cutting, scoring and folding a blank as shown in Figs. 7, 8, the parts 13, 16 forming the base, 12, 17 the side walls, 18, 15 the longitudinal partition, 11 the cover, 10 the cover locking strip and 14 the crosspartitions which are hinged to the side walls by means of triangular webs 19, 21. Openings 22 are provided in the base portions 13, 16 through which the operator may insert his fingers to bring together the two parts 18, 15 of the longitudinal partition as shown in Fig. 9. The carton is then positioned over the setting-up device so that the cross-partitions point towards the vertical faces 35 of the blocks 31, this being facilitated by vertical guides 33 having extensions 34 on either side of the longitudinal groove 32. As the carton is pressed downwardly, the free ends of the cross-partitions remain in contact with the tops of the blocks while the hinged ends engage the slanting faces 36 so that the carton is moved longitudinally and the cross-partitions are rotated to a substantially vertical position. The parts 18, 15 forming the longitudinal partition are provided with slots 23 as shown in Fig. 4 for receiving the reduced central portions of the cross-partitions, which are now in the position shown in Fig. 5. Finally, downward pressure on the longitudinal partition causes these central portions to snap over the projections 25 into the locking position shown in Fig. 6.

Title: Improvements in or relating to fuzes for rocket projectiles or the like missiles
IPC: F42C15/24
Filed: 1958-04-02
Abstract: 857,401. Ammunition fuzes. JUNGHANS A. G., GEB., and JUNGHANS, H. April 2, 1958 [April 3, 1957], No. 10670/58. Class 9(1). A direct action percussion fuze particularly for rocket missiles is provided with a safety mechanism to delay arming, which mechanism comprises a driving weight 29 and a counter-weight 32, the driving weight being arranged to set back longitudinally in the fuze when the missile is accelerating and by means of rack teeth meshing with a common pinion 31 drive the counterweight in the opposite direction, a firing pin latching means being controlled by one of the weights. The fuze body 10 is closed by a base plug 14 housing a primer 12 and by a nose cap 11 housing a plunger 15. Parallel bores 10a, 10b in the body 10 house the weights 29, 32 which surround guide rods 18, 19, the rods being connected at their upper and lower ends by transverse plates 20, 21 respectively. Riveted to plate 20 is a striker 22 and to plate 21 a firing pin 23. This impact transmitting linkage is held in the unarmed position by a spacer 26 carried by one arm of a lever 24 and bearing against plate 20, a pin 27 depending from the second arm being housed in a slot which is blocked by the counter-weight 32. A leaf spring 28 bears against the lever 24 to drive the lever to the unarmed position when the pin 27 is released. On set-back of the driving weight 29, the counter-weight 32 is driven forwardly by the pinion 31 the motion being controlled by an escapement wheel, fixed on the axle of the pinion and cooperating with a pallet oscillating on the fuze body 10. The movement of the weight 32 stresses a spring 33 extending into a blind bore in the counter-weight. Finally the driving weight becomes disengaged from the pinion and the drive of weight 32 ceases, whereupon the spring 33 returns the weight 32 to the base of the fuze. The pin 27 is then free and spring 28 swings the lever 24 carrying the spacer 26 from beneath the plate 20, leaving the fuze armed for operation on impact. A return forward movement of the driving weight is prevented by a leaf spring 37, secured to the body 10, which swings into the path of the weight after set-back.

Abstract: 528,744. Distributing fuel on and removing ashes &c. from furnace grates. ESKE, F. W. April 6, 1939, No. 10852. [Class 51 (i)] A bar 4 located transversely and adjacent to the upper surface of a furnace grate 1 is moved backwards and forwards from one end of the grate to the other for distributing fuel fed from a hopper 28 and for discharging ash into a hopper 29 at the rear of the grate. Any ash falling through the grate bars is blown towards the rear of the ashpit by a current of air into a receptacle 32. The bar 4 is tilted slowly as it moves towards the rear of the grate from an almost vertical position at the front of the grate to a position parallel with the grate surface at the rear. The bar is provided at its ends on a level with its lower edge with extensions 6 which pass through slots 7 in the side walls and carry rollers 9 running in guide rails 10. To the extensions 6 are also fixed rods 12 provided at their upper ends with rollers 14 moving in guide rails 15, and links 17, 19, the latter being connected. to an endless rope or chain 20 driven by an electric motor. The front ends of the guide rails 10, 15 are connected by semicircular rails and the guide rails converge towards the rear of the grate where they unite. As the bar is moved by the rope or chain 20 towards the rear the rollers moving in the upper and lower guide rails cause the bar to tilt gradually to the horizontal position. The motor driving the rope or chain 20 is then reversed and the bar travels towards the front of the furnace in a horizontal position with both sets of rollers in the lower track until it reaches the semicircular guide rails at the front when the bar is again tilted into the position shown at 4a. The links 19 on one side of the grate are provided with projections 37 which operate reversing switches 39 at the front and rear of the grate. The slots 7 in the side walls are sealed by flexible strips or shutters secured to the extensions 6 adapted to move with the blade 4 and to wind upon and unwind from spring loaded spindles in casings 38.
