Title: Improvements in or relating to intermediate explosive primers
IPC: F42B1/04
Filed: 1942-07-29
Abstract: 576,219. Blasting detonators. TAYLOR, J., WRIGHT, H. R., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. July 29, 1942, No. 10586. [Classes 9 (i) and 9(ii)] An intermediate explosive primer adapted to transmit an enhanced impulse from a detonator or detonating fuze to a flame-insensitive cast explosive charge in the primer has a smaller charge of compressed explosive, more sensitive than the cast main charge, but also flame-insensitive, compressed within a tube which is interposed between the detonator and the larger charge of the primer in detonating contact with the main charge, the tube projecting at its closed end into a reduced part of the casing which receives the detonator. The larger and less sensitive charge for the primer may be cast from a molten mixture of T.N.T. and tetryl, or T.N.T. and pentaerythritol tetranitrate, or T.N.T. and cyclo-trimethylene-trinitramine, while the interposed relatively more sensitive charge may consist of compressed pentaerythritol tetranitrate, compressed cyclo - trimethylene - tri - nitramine or other compressed sensitive explosive. The primer shown comprises an open-ended casing 1 with an enlarged portion and an inner tubular member 2 closed at its inner end which is connected inside the casing at a shoulder by polyvinyl-acetate cement 3. The enlarged portion of the casing has cast therein the less-sensitive charge 10, a portion of which penetrates the inner tube to contact with the compressed more-sensitive charge 9 contained therein. The reduced portion of the casing is split at 4 and shouldered at 6 so that it can be easily clamped around a detonator or detonating fuze by a ring 8 when the detonator and primer are fitted together under field conditions. Specification 547,758 is referred to.

Abstract: A machine of the type claimed in the parent Specification comprises a housing enclosing the work-feeding and inking mechanisms and having a narrow opening through which a work-piece is presented to the work-feeding mechanism and having outer surfaces inclined towards the opening to guide the work-pieces to the opening.  One feed roll is spring-pressed towards the other and is mounted on a treadle-operated support so that the rolls may be separated.  The roll may be adjusted to fix the distance apart of the rolls.  A guard is also provided on one side of the inking roll to prevent work-pieces being deflected. The edge of a sole S, Fig. 4, is fed by rolls 12 and 14 to an inking roll 10.  The roll 12 is made of a yielding material, e.g. rubber, and its position is determined by the engagement of pin 84 with a portion 86 of a sleeve 88 which slides in the carrier sleeve 74 and is adjusted by a screw-pin 90.  A compression spring 94, adjustable independently of the cross-pin 84 and the screw 90, provides yielding pressure for the roll 12.  Roll 14 is rigid and is supported on a yoke 22, Fig. 2, carried by a bracket 28 capable of heightwise adjustment.  Adjustment of the yoke 22 is also possible to bring the roll 14 directly above a flange 38 on the side of the inking roll, the flange carrying ink for coating the margin as well as the peripheral edge of the sole.  The feed-rolls are driven by an endless belt 102 passing over pulleys 62 and 76 and over pulley 104 which is driven by belt 114 from a <PICT:0645451/III/1> trough 140, Fig. 3, which merges with a cup 142 which receives ink from the inverted bottle 146.  The position of the trough and inking roll is determined by a screw 160.  The quantity of ink on the roll 10 is controlled by a scraper plate, and a guide member 180 prevents motor, not shown.  A treadle, not shown, operates a rod 134 connected to a lever 26 which carries the roll 12 and effects separation of the rolls.  The inking roll 10 is mounted in a <PICT:0645451/III/2> <PICT:0645451/III/3> deflection of flimsy soles.  The machine cover parts 184 and 186, Fig. 2, contain a gap through which the work-pieces are presented.

Title: Improvements in razor blade feeding mechanism for razor blade sharpening machines
IPC: B24B41/00
Filed: 1928-04-13
Abstract: 298,868. Larsson, S. April 13, 1928. Cutting-edges, treating; feed devices.-In a machine for sharpening safety razor blades in which the blades are carried by an endless belt or chain to the sharpening-device, the blades are fed automatically from a pile on to the belt. The belt 1 has thereon pins 2 to engage the holes in the blade, and as the belt moves, slots therein engage and rotate a sprocket wheel 5 mounted on a shaft 6, on which also are rotatably mounted levers 8, 13, the lever 8 also being movable on a pivot 10 towards and from the lever 13, under the control of a spring 15 and a guide arm 12. On the face of the wheel 5 are teeth 19 which engage and move the lever S against the action of a spring 17. The lever is engaged by a member 23 carried by a rod 21 slidable in guides 22, 22<1>. the member 23 being pulled to the left, Fig. 1, by springs 25, and the rod 21 carries a slide 24 which engages the lowermost blade in a weighted pile 29 contained in a magazine 30. Upon movement of the levers 8, 13 to the left by means of the teeth 19, the member 23 is pulled by its springs and the slide pushes the blade into a channel 28 until the foremost hole in the blade, which is inclined to the belt 1. is engaged by the pin 2<1> on the belt, when the member 23 engages a stop 27. The blade is then pulled forward by the belt and is pressed thereon, to engage also the next pin 2, by a spring- pressed guide 33. Upon the lever 8 reaching the end of its stroke, it is moved laterally by a cam 35 to disengage the teeth 19 and is moved back, until the member 23 engages a stop 26, by the spring 17; the operation is then repeated. In a modification, the wheel 5 is driven by one of the sprocket wheels driving the belt 1, and the feeding stroke of the plunger is positive, the springs 25 causing its return; the blades are fed on to the belt where it runs over its driving- sprocket.

Title: Secondary coolant purification system
IPC: G21C15/00
Filed: 1975-03-17
Abstract: 1490273 Nuclear power plant COMBUSTION ENG Inc 17 March 1975 [18 March 1974] 11034/75 Heading G6C In a secondary coolant system of a nuclear steam supply system which includes at least one steam generator 12, a turbine 22, a condenser 24, a condensate pump 26 and a means 38 for demineralizing the secondary coolant, the coolant is diverted around the demineralizer 38 via a by-pass 34 when its level of radioactivity exceeds a predetermined level. Even with the condensate demineralization of the full flow of feedwater delivered to the steam generators 12, these still have a tendency to concentrate impurities in the feedwater and for this reason it is necessary to maintain a continuous blowdown of the steam generators 12, the blowdown being siphoned off by piping 60, cooled by a heat exchanger 64 and then passed back via lines 82, 86 to a point between the condensate pump 26 and the demineralizer 38. Should one or more of the steam generator tubes 16 fail, radioactive primary coolant will leak into the normally non-radioactive secondary coolant and as the resin regeneration system 40 of the demineralizer 38 is not equipped to handle radioactive wastes, use is then made of the by-pass 34. Upon detection of radioactivity in excess of a predetermined allowable level by a blowdown line monitor 62 or a condenser vacuum vent monitor 30, a signal is sent by electrical conductors 66 or 67 to the actuation means of bypass valve 32 and flow control valve 36. Although the demineralizer 38 is now bypassed, the system can remain in operation by cleaning the secondary system of its radioactivity using an auxiliary ion exchange system 91 which includes blowdown ion exchangers 88, 90 having throw-away resin beds. Upon receipt of a signal from the radiation monitors, the appropriate actuating devices open a flow regulation valve 74 and close a by-pass valve 72, and the blowdown flow is diverted to the ion exchange system 91. The flow passes through a heat exchanger 70 and its temperature is monitored by a temperature detector 78. When the blowdown flow has attained a sufficiently low temperature, detector 78 sends an activation signal to a by-pass valve 80 and the flow is diverted through the ion exchangers 88, 90. Subsequent to this cleaning action, the coolant is returned through a conduit 92 back to the secondary feedwater chain 58.

Title: Method and apparatus for sealing covers on open topped, more especially dish-shaped,packaging containers having a margin which consists at least superficially of a thermoplastic material
IPC: B65B7/16
Filed: 1963-03-21
Abstract: 1,031,173. Packaging. KALLE A.G. March 21, 1963 [March 23, 1962], No. 11311/63. Heading B8C. A method of sealing a container having a thermoplastic margin comprises placing the container into a box deeper than itself, heating a film of synthetic plastics material weldable with the margin, bringing the box up against the stationary film to form an air-tight seal, removing the air from the box to draw the film on to the contents and margin, and pressing the film and margin together. The containers B and the film F are supplied to the box 5 by conveyers 1, 2, the film being passed under a heater 3 which softens at least that part which will eventually cover the opening of the container. After a container has dropped into the box 5 the conveyers are immobilized and a linkage system 10 lifts the box up against the film until an air-tight seal is formed, whereupon the air is extracted from the box through a vent duct 8, thus drawing the film F down on to the margin R of the container. By lifting the box further it is brought up to a welding device 11 comprising a welding jaw and a severing edge, the margin R and the film F being clamped between the jaw and the margin 15. After welding and severing the container is ejected from the box by moving the box base upwards by a linkage 9. To better enable the container to be evacuated the margin may be grooved; evacuation may be performed by displacing the air with another gas and then extracting the said gas.

Filed: 1925-05-04
Abstract: 254,833. Whitehouse Bros., Cannock, Ltd., and York, A. M. May 4, 1925. Hand tools. - The heads of axes, hatchets, and other edge tools having an eye for the handle at the back of and in the plane of the blade are produced from rectangular blanks by tools which pierce the eye and shape it internally and externally, the metal at the front of the eye being swaged afterwards to form the blade. The edge of the blank, Fig. 1, is formed with a depression a by pressing it in a die with a correspondingly shaped rib at the bottom, the depression a serving as a guide for the nose of the piercing-punch for the next operation of forming the eye, which is carried out by a die and punch. The die has lateral concaved recesses to shape the external sides of the eye b, an opening at the bottom for the nose of the punch, and V-shaped shoulders at the sides of the opening to shape the bottom edge b<1> of the eye. The upper edge b<2> of the eye is shaped by shoulders at the top of the punch. This shaping of the eye may be performed by one set of tools, or in a number of stages by two or more sets of tools. Internal fins left in the eye are then removed by drifting, and fins on the edges b<1>, b<2> are clipped off. The portion c of the blank is swaged to form the blade, and the circular eye b flattened to theusual oval shape.
