Filed: 1953-08-14
Abstract: 726,295. Blasting. LITWINOV, N. Aug. 14, 1953, No. 22418/53. Class 68(1). The firing of a plurality of blasting charges 1-7 in a predetermined sequence is arranged by holding the associated fuses of equal length individually and out of contact with one another in an apparatus 10 so that the ends 11-17 of the fuses protrude therefrom to varying extents, trimming the protruding ends back to the adjacent side of the apparatus, lighting said trimmed ends individually and then simultaneously releasing the fuses from the apparatus. The length of the protruding end of a fuse is dependent upon the order in which the associated charge is to be fired, i.e., the fuse of the first charge to be fired protrudes the furthest, and vice versa. One embodiment of the apparatus consists of two matching hinged parts 20, 21 provided with a plurality of matching slots 23, and a spring clamp 25 to press the parts together, when closed about the fuses, to grip the fuses. The edges 26, 27 of the parts 20, 21 facing the protruding fuses lie in a plane inclined at 45 degrees to that of the fuses within the apparatus. A second embodiment of the apparatus consists of slotted matching parts in which one part is pushed into grooves provided in the other part. A third embodiment of the apparatus consists of a flat board having two rows of holes in which each fuse is inserted to pass through a hole in each row.

Title: Shaft seal
IPC: F16J15/40
Filed: 1962-06-12
Abstract: 980,646. Seals. SOC. ALSACIENNE DE CONSTRUCTIONS MECANIQUES. June 12, 1962 [June 26, 1961], No. 22428/62. Heading F2B. A sealing arrangement between a wall 2 across which a fluid pressure differential exists and a shaft 1 freely extending through an aperture 4 in the wall and supported for movement relative thereto comprises a tubular sleeve 11 snugly fitted around, and supported by, the shaft on the higher pressure side of the wall and urged into end face sealing engagement with the wall surface around the aperture by means of the higher fluid pressure while remaining centred around the shaft. A gas at superatmospheric pressure is contained in an enclosure 3 on one side of the wall, the other side being exposed to the atmosphere. The shaft is supported for rotational movement by bearings 5 carried by arms 6 projecting from the walls. A pin 13 projecting from the wall 2 into a slot 14 in a flange 15 on the sleeve prevents rotation of the sleeve by the shaft while allowing its radial movement relative to the wall. Axial displacement of the sleeve is limited by stops 28 on the end of the sleeve engaging the housing 16. The sleeve is surrounded by a housing 16 fixed to the wall and having a bore 25 through which the shaft 1 extends freely. Sealing fluid such as oil is pumped into the housing at 21 at a pressure higher than that of the gas and passes partly through the bore 25 and a vent 29 into the enclosure 3 where it may be recovered and partly through the clearance space between the shaft and the sleeve and through the aperture 4 into a housing 26 where it is removed through an outlet pipe 2 to be recirculated. The oil pressure in the chamber 18 acts on the sleeve to maintain it into sealing engagement with the wall. Alternatively, instead of an auxiliary liquid, the fluid in the enclosure 3, which may be liquid or gaseous, may serve as the sealing medium in which case the housings 16, 26 are dispensed with. The shaft may also be mounted for axial or for both axial and radial displacement.

Abstract: 376,526. Liquid fuel burners. BOER, K. W. D., 89A, Schietbaanlaan, Rotterdam, Holland. Aug. 12, 1931, No. 22757. [Class 75 (i).] In a device for automatically shutting off the fuel supply to a liquid fuel burner, the load of a piston normally supported by the pressure of the air supplied to the burners, releases by means of a double arm lever a locking pin by which a spring-loaded piston valve controlling the fuel supply is normally held open, when the compressed air supply fails to support the piston. Compressed air enters a cylinder 2 containing the piston 3 by a pipe 1. One end 10 of a double arm lever 9 pivoted at 8 to an arm 7 on the cover 6 of the cylinder 2, lies in the path of a weight 5 on the piston rod 4. The other arm is hooked at 11 to support the locking pin 12, the lower end of which passes through a hole 15 in a piston rod 17 and into a guiding block 13, and prevents the piston valve 18 from closing under the action of a spring 20. The device is manually re-set.
