Title: Improvements in or relating to the production of ammonium nitrate charges
IPC: C06B21/00
Filed: 1947-02-07
Abstract: 632,201. Moulding explosives. DAVIS, W. R., BUCKINGHAM, J., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Feb. 7, 1947, No. 3663. [Class 87 (ii)] [Also in Group XXII] Ammonium nitrate charges of the kind comprising fusion promoting ingredients and a chromate compound, sensitiser of thermal decomposition are produced by building a solid deposit 16 on a rotating mandrel 14 which is first partially immersed in and then (by mechanism 15) slowly withdrawn from a liquid kept at constant level in a shallow bath 12, the liquid being molten ammonium nitrate composition at a temperature sufficiently low to prevent its decomposition and sufficiently above the temperature at which crystals begin to be deposited from the melt. The mandrel may be steel, of slightly tapered cylindrical form to facilitate its withdrawal from the completed deposit; or it may be a cylinder turned from a charge of ammonium nitrate previously made, thereby permitting solid, i.e. non-annular, charges to be produced of the same composition throughout. In the arrangement shown the molten ammonium nitrate composition is prepared in a jacketed vessel 1, having a stirrer 2, and is led to jacketed vesels 6 and 6<SP>1</SP>, with stirrers 7 and 71, where the chromate compound is added. Scum is removed, and the melt in the vessels 6 and 6' is delivered into a tank 10, both the vessels being used together when it is desired to fill the tank 10 quickly. The bath 12 has a weir 17 at one end and a weir 18 at the other, and the level of the liquid in the bath 12 is kept constant by the action of a circulating pump 11. Hot oil is circulated in the chamber 19 and in the jacket 20. The thickness of the layers deposited on the mandrel is controlled by a doctor knife 13. The rate of cooling of the deposit may be controlled e.g. by a current of air. Specification 570,075, [Group XXI], is referred to.

Title: Improvements in or relating to balances for sorting objects by weight
Inventor: SCHOOT JELLE VAN DER
IPC: B07C5/18
Filed: 1970-01-28
Abstract: 1298713 Sorting by weighing VAN KATWIJKS INDUSTRIEEN N V 28 Jan 1970 [31 Jan 1969] 4087/70 Heading G1W A stepwise sorting apparatus comprises a plurality of balances the first of which is operable to discharge at the same station objects, such as eggs, having a weight above or below a predetermined range. Two balance levers 4, 5 having adjustable weights 6, 9 provided on their thrust arms are mounted coaxially on a shaft 3 housed in a support 2 fixed on a vertically reciprocating support rail 1. The lever 4 has a load pan 7. A finger 8 projects from lever 4 and extends across and above the top of the load arm of lever 5. Lever 4 has a pin 10 and lever 5 has a pin 11 both of which project upwardly. An arm 14 pivoted about a shaft 13 fixed on a support 12 is mounted above the two levers and carries a stop 15 having a recess 16 and a stop 17 having a recess 18. In operation an object 19 is supplied in a stepwise manner by a conveyer 20 to a position above the load pan 7 whereafter the rail 1 is initially raised so that the load pan supports the object. If the object is between a preselected maximum and minimum weight the lever 4 will tip until the finger 8 rests on the load arm of lever 5. Thus on the further raising of the support rail 1 the pin 10 remains clear of the stop 15 and pin 11 remains clear of stop 17. Hence the rail 1 subsequently descends with the object on the pan and the conveyer moves it along to the next balance. An underweight object will not tip lever 4 and on rising the pin 10 co-operates with the recess 16 causing the arm 14 to pivot and hence rolling object off the pan 7. An overweight object tips both levers and on rising the pin 11 co-operates with recess 18 in guide 17 and again causes the arm 14 to pivot so that the object is rolled off the pan. In another embodiment, Figs.4, 5, 6 (not shown) a single stop (28) is provided on the load lever (23) so that when an object within the given weight range is placed on the pan (27) the stop (28) co-operates with a pin (35) on a reciprocating ejector device causing the compression of a spring and rendering the ejector device inoperative. An underweight object will not depress the lever (23) and the pin (35) will pass over the stop (28) when the ejector moves forward and hence the object will be ejected. An overweight object will tip the lever (23) and a further lever (24), in a similar manner to that in the first embodiment, and as reciprocation of the ejector the pin (35) will pass under the stop (28) and again the object will be ejected.

Title: Coupling device for trucks, in particular for mine cars
IPC: B61G7/04
Filed: 1955-02-11
Abstract: 764,801. Coupling rail vehicles. HALSTRICK J., and HALSTRICK, W. Feb. 11, 1955 [Feb. 11, 1954], No. 4101/55. Class 103(5). A coupling device, for railway trucks having hooks and links, consists of a fixed framework built of members 3-6 located beneath the truck rails, Figs. 2, 6 and provided with rails 7-10 on which may move a chassis built of members 11, 12, 17 and carrying coupling elements 26, 33. The coupler 26 is part of a frame which can be moved relatively to the chassis on rollers 19, 20, by the operation of a piston rod 25 reciprocable in a cylinder 18. The coupler.26 also pivots about rollers 19 and is guided by means of a roller 27 over an inclined rail 28 and a spring supported rail 30. Guideways 31 and 32 move the shackle and hook respectively which are not to be coupled. The shackle lifter 33 may be pivoted by levers 34 moved by the frame of the coupler 26. Bell crank levers 36, 37, Fig. 3, pivoted at 35 to the chassis are moved to carry the chassis along by the axle of the second truck abutting stops 38, and are guided by rollers 39 which after coupling run beneath a guideway 40 to release the chassis from forward movement. In the initial position the levers 36, 37 are held by arms 41 which may pivot on the axle 42. In operation the second truck strikes the stops 38 and propels the levers 36, 37 and the chassis along. At this moment the shackle of the first truck rests on the lifter 33, and as the trucks move further the piston rod 25 is actuated to move the coupler 26 forwardly with respect to the chassis so that the coupler runs up the rails 28, 30 and raises the hook of the second truck. The frame of the coupler then strikes the linkage 34, causing the lifter 33 to rise and present its shackle to the hook, and at the same time bearing against and pivotally depressing the coupler 26 on the spring platform 30. The backward pivoting of the coupler 26 then allows the hook and shackle to engage. The levers 36, 37 are then pivoted downwardly by the guide-rails 40, and the whole chassis, together with the levers 36, 37, is returned to its initial positions for the next operation. In a modification, Fig. 9, the movable frame is dispensed with and the coupler 50 is pivoted anticlockwise by a piston rod which moves to the right. The pivoting of the coupler 50 causes it to strike a control head 57 which operates a compressed air cylinder 59 to raise the shackle lifter 56. The lifter 56 on pivoting upwardly presses back the coupler head 51 to make the coupling. The coupler and lifter then return to their original positions and the chassis moves back as already described.

Title: Improvements in and relating to warp stop-motions for looms
IPC: D03D51/20
Filed: 1935-02-09
Abstract: 438,925. Loom warp stop-motions. WELLEMIN, F., 1A, Karlin Pobrezni, Prague. Feb. 9, 1935, No. 4219. Convention date, Feb. 9, 1934. [Class 142 (i)] Relates to stopmotions of the kind described in Specification 382,328 in which a drop wire falls when a warp thread fails and stops the reciprocation of toothed bars movable between stationary toothed bars, and consists in spring devices for imparting motion to the reciprocating bars by their driving means. In the form shown in Fig. 1, a lever 21 is loosely mounted on a shaft 14 carrying a lever 15 for reciprocating the toothed bars and is oscillated through link and lever mechanism from a rod 28. The hub of the lever 21 is engaged by a spring 18 secured to the hub of the lever 15. Normally, the spring causes the parts 21, 15 to oscillate together, but when the reciprocation of the toothed bars is prevented, the lever 21 moves relatively to the lever 15. The spring may be mounted on the hub of the lever 21 and engage the hub of the lever 15. In the form shown in Fig. 5, a tubular connecting-rod 28 is arranged within a hollow member 38 having an operating projection 27. Springs in engagement with washers and collars cause the parts 28, 38 normally to move in unison, but allow the connecting-rod to continue to move when the projection 27 is stopped. In another form, the connecting-rod is formed with a tubular part carrying springs adapted to embrace a ball on a rod passing through the hollow part. When the reciprocating bars are stopped, the ball forces the springs apart and the rod slides between them. In the form shown in Fig. 6, the bars 13 are driven by a pin 17 engaged in recesses in the bars and acted upon by a spring 44 secured to the oscillating member 15. When the bars are stopped, the pin slides along the recesses in the bars and its displacement is used for stopping the loom.
