Title: Improvements relating to field mines
IPC: F42B23/16
Filed: 1955-03-10
Abstract: 765,026. Land mines. SORLINI, R. March 10, 1955, No. 7063/55. Addition to 693,810. Class 9 (2). The mine claimed in the parent Specification having a truncated conical body 1 is provided with a bush 7 fitted in a central bore in the base and housing a detonator 8 aligned with a striker 25 carried by a cap 15 housed in the mine cover 2. The body 1 is closed by a nose piece 6 which holds the bush 7 in place and forms a housing for an impermeable container 11 depending from the bush. Within the container is an auxiliary charge 12 in contact with a delay action fuze 14 mounted in the bush and leading to a detonator 36. A conical head 32' as in Specification 693,479 may be attached to the nose piece 6. Extending from a bore 20 in the cap 15 is the head 22 of the striker 25 held in the safety position by a transverse pin 27 passing through the head 22. Before placing the mine in the ground, the pin 27 is removed a transverse. pin 32 in engage- .ment with a groove 23 being provided to hold the striker in the armed position. When a given pressure is applied to the head 22, the locking pin 32 is thrust outwardly releasing the striker, which is then driven by its spring 29 against the detonator 8. The detonator 8 ignites the charge 12 which in turn ignites the delay fuze 14 to ignite the detonator 36 and thence the main charge 3. The charge 12 projects the mine out of the ground, so that the main explosion takes place above ground. The striker may also be released by a pull on a wire 34 attached to the pin 32.

Title: Improvements in the generation of acetylene
IPC: C10H13/00
Filed: 1942-05-28
Abstract: 559,198. Acetylene. SHAWINIGAN CHEMICALS, Ltd. May 28, 1942, No. 7214. Convention date, Oct. 21, 1941. [Class 2 (i)] Acetylene is generated by a process which may be regarded as a combination of the previously known wet and dry processes, the essential characteristic of which is that water is added to the calcium carbide in an amount slightly in excess of that necessary for complete reaction, the whole of the water being added at once and adjacent the addition locality of the calcium carbide. The apparatus comprises a horizontal trough provided with one or more dams to maintain an even depth of reactants, and also provided with impellers to force the reacting mass along the trough to the outlet at which the completely reacted lime is discharged. The apparatus also includes towers in which steam and lime dust are removed from the acetylene. An additional feature of the invention comprises the return of the hot sludge from the washing towers to the inlet port of the apparatus where it is used instead of fresh water to slake the carbide with consequent avoidance of waste of heat and loss of lime. The excess of water which is used according to the invention is adjusted so that the final lime is discharged in a substantially dry condition after the carbide has been slaked and evaporation due to heat of reaction has taken place. In the Figure, carbide is admitted from hopper 10 via screw feed 11 to the chamber 15. Water or hot lime sludge from the washing tower 60 is admitted at 18, and the reacting mass is forced along the trough by the impellers 17 mounted on the shafts 16. The dam 21 serves to maintain an even depth of reactants. From the trough 15 the reacting mass passes through two further troughs 30 and 40 each provided with impellers. The completely reacted lime is discharged via the spiral drives 44 and 42, which serve as a gas seal. The acetylene passes through the offtake 50 to the washing tower 60 where suspended lime is removed by upward passage against a water spray from 61, and/or by passage against sprays of sludge from sprays 67. The sludge so used is obtained from the sludge well 62 via the pump 63. From the washing tower 60 the gas passes to the cooling tower 70 where upward passage against cold water sprays 77 and 78 condenses the steam and cools the gas before it leaves by the duct 80. The cooling water and condensed steam collects at 72 and passes through pump 74 and cooler 75 for re-use in the sprays 77 and 61.

Title: Sub-standard cine camera
IPC: G03B1/22
Filed: 1969-02-11
Abstract: 1,206,252. Cine-camera spool drive. AGFA-GEVAERT A.G. Feb.11, 1969 [Feb. 14, 1968; March 28, 1968], No.7243/69. Heading G2E. In a sub-standard cine camera a reciprocating film pull-down mechanism and a film take-up spool are driven by a common motor the spool driving means deriving its motion from a reciprocating member, which may be the pull-down mechanism itself, through a hairpin spring coupling which allows lost motion and avoids the necessity of using a frictional coupling. As shown, the reciprocating member is the pulldown mechanism and the spool driving means includes two intermeshing gearwheels, 12, 13 coupled to the take-up spool (not shown) and arranged to be alternately driven by an arm 14, having two pawls 14a, 14b, which arm is pivoted at one end of a first lever 15 pivoted at its other end about a pin 16 fixed to the camera. A second lever is also pivoted at pin 16 and is driven by a hairpin spring 18 engaging flaps 17b and connected directly to the film pull-down mechanism 8. Lever 15 has fixed pins 15a, 15b so that it may be rotated by lever 17 when arm 14c engages one of the pins. In operation, when the pull-down mechanism 8 begins its movement in one direction, one of the pawls 14a, 14b engages, while the other disengages one of the gearwheels 12, 13 owing to the pivoting movement of arm 14. When one of the fixed pins 15a, 15b is engaged by arm 14c the lever 15 rotates about pin 16 to advance the gearwheel engaged by a pawl. The other gearwheel is advanced similarly during the opposite movement of the pull-down mechanism 8. In a second embodiment Fig. 3 (not shown) the pawls 14a, 14b are individually pivotable as one arm of a two-armed lever (15) and are spring biased for engagement with gearwheel 12, 13. The lever 15 may be driven by another reciprocating member driven by motor 1.
