Title: Improvements in or relating to hole-drifting and tube-expanding tools
IPC: B21D39/12
Filed: 1949-01-07
Abstract: 662,443. Rolling annular bodies ; tube expanders. L' OUTILLAGE ROTAX. Jan. 7, 1949 [April 22, 1948], No. 509/49. Class 83 (iv). In a machine for drifting and chamfering holes in plates, or expanding and flaring tube-ends in the holes, of the type comprising a rotary tubular body 5 housing expansion and flaring rollers 9, 10, urged outwards and rotated by an axially displaceable taper pin 13, the tubular body 5 bears upon and is rotatable without axial displacement in an abutment member 3 and presents an abutment for an adjustable stop 25 carried by the taper pin 13. The rotary body 5 has interchangeable heads 6 screwed therein for drifting and chamfering different sized holes and carrying two slightly tapered expansion rollers 9, two conical flaring rollers 10, and a third expansion roller 9a longer than the rollers 9 and arranged so that it flattens out the ridge produced between the rollers 9 and 10. Interchangeable heads for expanding and flaring the ends of tubes in the holes are similar to the heads 6 but carry flaring rollers 10, each having an annular groove for flanging the ends of the tubes over the edges of the holes. Slots 8, Fig. 2, for the rollers have a width at the outer periphery less than the diameter of the rollers which are held in the slots at the inner periphery by projections 12 on a bush 11 inserted in the head 6. The pin 13 has an opposite and equal taper to the rollers 9 so that the rolling edges produce a non-tapered bore as the pin is moved forward and rotated. The pin 13 carries an adjustable stop nut 25 having an integral sleeve and buffer ring 23 and an intermediate thrust bearing 28 attached thereto by a threaded sleeve 24. The nut 25 is locked on the pin 13 by a lock nut 27 at a predetermined position such that the buffer ring 23 engages the end of the body 5 and prevents the pin 13 from moving further forward. In a modification, a stop nut 25 and lock nut 27 only are used, the stop nut being notched to engage a notch on the end of the body 5. In this case the pin 13 has a left-hand thread so that as the pin 13 continues to be rotated it will be screwed outwards in the stop nut 25 and retracted from the tubular head.

Title: Improvements in explosives
IPC: C06B23/00
Filed: 1937-03-06
Abstract: 497,145. Explosives. TRIGGS, W. W. (United States Powder Co.) March 6, 1937, No. 555. Drawings to Specification. [Class 9 (ii)] An explosive mixture comprises a nitrocompound, such as dinitrobenzene, trinitrobenzene, dinitrotoluene, trinitrotoluene, picric acid, or styplinic acid, an oxidizer, such as an alkali, ammonium or alkaline earth nitrate or lead nitrate and, in addition, a nitro-derivative of naphthalene and an organic promoter consisting of one or more aliphatic or aromatic compounds in which the " molecular length," calculated from the values of atomic radii and bond angles given in the Specification, is within 0À1 angstrom unit of being equal to 3À83, 4À19, 4À84 or 5À13 angstrom units. The term " molecular length is defined as being the equilibrium distance between the atoms (exclusive of hydrogen atoms), which are farthest apart from each other in a molecule of either the aromatic or aliphatic type. Examples of such an organic promoter are ethyl acetate, methyl propionate, propanol, butanol, proprionic acid, lactic acid, butyric acid, alanine, butyric aldehyde, benzyl alcohol, benzylamine, benzaldehyde, benzoic acid, salicylic acid, 1À2-dichlorethylene or glycme. In general, the amount of promoter added to the nitronaphthalene is from À005 per cent to 2 per cent by weight of the entire explosive mixture. In making the explosive, the nitronaphthalene and the nitro-compound are melted together and to the molten mass is added the promoter and the necessary moisture, which is generally in the form of a 50 per cent calcium nitrate or aluminium nitrate solution and finally the powdered and warmed nitrate is incorporated in the mixture so that the particles of nitrate are coated with the organic explosive mixture. To produce a plastic powder, an additional quantity of a suitable mixture containing generally tetranitronaphthalene, dinitrotoluene and the promoter is added to the mixed explosive. Various examples are given in the Specification.

Title: Improvements in and relating to a method of detecting and eliminating indivisible foreign bodies from pre-crushed raw materials
IPC: B02C1/02
Filed: 1962-01-08
Abstract: In a crusher having a component equipped as overload protection and allowing a foreign body to pass, the component operates, when the foreign body exceeds a certain size, a switch by means of which the drive of the subsequent conveying or processing unit is slowed down or stopped, possibly with simultaneous emission of a warning signal, or by means of which devices are actuated which temporarily deflect the flow of material containing the foreign body.  As an example, a single toggle jaw crusher has its crushing jaw supported through a pressure plate on a hydraulically-operated cross-member the deflection of which is used to actuate a switch.  Specification 812,507 is referred to.

Suitable salts are the fluorides, sulphates and phosphates of calcium, barium and strontium, and the mercury oxide is preferably partially combined chemically with an oxide of nitrogen.  The mercury oxide may be introduced as a solution of mercury nitrate or acetate, or as the carbonate, an oxide, or basic nitrate mixed with water. When using calcium sulphate is the form of plaster of paris, the mixture may be allowed to set to a hard mass and broken up, or extruded before setting.  Dry barium sulphate or calcium fluoride may be mixed to a paste and formed into pellets, or a gelatinous precipitate of calcium fluoride may be used.  Treatment of the mixture may be carried out at from room temperature to 400 DEG C. (preferably 165 DEG -200 DEG C.) and at normal, reduced, or increased pressure; at normal or increased pressure a stream of dry air is passed over the mixture.
