Title: Improvements in weighing scales
IPC: G01G1/26
Filed: 1928-10-19
Abstract: 309,477. Toledo, Scale Co., (Assignees of Hem, H. 0.). April 11, 1928, [Convention date]. Computing-apparatus; pendulumweight apparatus.-A weighing scale of the semi-automatic lever type wherein the weighing capacity may be changed, is provided with means for simultaneously depositing a first unit weight and an additional unit weight upon the scale lever, or lever mechanism, in a manner such that the weights act in opposition to each other with the first weight having lesser counterbalancing effect with the first additional weight. Loose-weight apparatus. - Co-axial with the fulcrum of the scale lever 3 is fixed a shaft 40 upon which are pivoted three bell-crank levers 41, 54, 62 for removing the capacity-changing unit weights 43, 57, 63 from the scale beam or depositing them thereon. The bell-crank levers are actuated by a system of cams 50 rotated by an external hand-wheel on the cam shaft 48. In the zero position shown, the unit weights 57, 63 are raised out of action and the unit weight 43 rests on the platform spider 4, thus maintaining the usual pendulum in its upper position with the indicating pointer at the zero mark, the machine being capable of weighing automatically within the lowest range of the dial, for example, from 0 to 1 kgm. By rotating the hand-wheel in steps cf one sixth of a revolution the cam and lever system removes and deposits the weight 43 and successively deposits the weights 57, 63 so as to raise the weighing capacity in steps of 1 kgm. to 6 kgms., and finally restores the machine to its initial weighing capacity. At each movement of the hand-wheel an additional cam actuates a. lever 66 connected, by a rack rod 69 to two discs 72 each bearing the numerals 0 - - 5 to indicate the kilogram setting of the machine upon the weight scales. The unit weights 57, 63 when on the scale lever are supported by screws 61 which afford means for adjusting the position of the weights. Instead of screws 61, resilient blade springs, acting also as shock absorbers, may be employed. A resilient support may be provided for the unit weight 43. Links.-The platform support or spider 4 is prevented from tilting by means of check links 7 each consisting of two pairs of flat bars with bearing blocks 13 at the ends, one pair forming a push connection and the other pair a pull connection. Vibration, preventing and neutralizing. - A dashpot 24 is mounted on the base 1 and is connected to the scale lever 3 by a yoke 26 in the manner described in the Specification of the divided application 326,809.

Abstract: 1329489 Self-propelled projectile and launching tube therefor SARMAC SA 29 June 1971 [10 July 1970] 30473/71 Headings F3A and F3C An assembly comprises, in one embodiment, a self-propelled, finned projectile 1 Fig. 1, locked in a combined container and launching tube 3 by means of a cap 14 which pushes the fins 9 outwardly so that projections 11 engage in slots 12 in the container wall. When the projectile is fired, the propellant gases readily expel the cap 14 and a closure 5 thereby allowing the fins to move inwardly and release the projectile. In another embodiment, Fig. 12, locking is provided by a resilient ring 32 which is expelled along with the cap 14 and closure 5. In a further embodiment, Fig. 15, the fins 9 are folded forwardly and locking is provided by spring leaves 36. In yet another embodiment, Fig. 17, locking is provided by parts 42. Slots 44 in these parts engage rivets on the fins 9 and allow the parts to fall away in flight. Spring leaves can be used to similar effect (Fig. 16, not shown). In a still further embodiment (Figs. 19 and 20, not shown) the projectile fins are folded laterally around the Venturi. Various modifications are shown in the remaining Figures.

Abstract: <PICT:0431619/IV/1> <PICT:0431619/IV/2> The method of the parent Specification for producing bands and foils of polymerization products of aryl olefines or similar brittle artificial substances such as polystyrol which are flexible and yielding in every direction according to which the artificial mass is squirted from a nozzle and the formed product subjected both to longitudinal and transverse stretching is applied to tubular extrusion, the artificial material being extruded from an annular nozzle and thereupon longitudinally tensioned and transversely stretched by drawing, at a greater speed than the speed of extrusion, over a spreading device provided on the centre piece of the nozzle, or inside a constraining member wherein it is inflated by compressed air.  The artificial mass b in the press a is extruded at a raised temperature from the annular nozzle c, and the formed tube f is drawn over the two curved guides e at the middle part d of the nozzle.  The outer sides of the curved guides are preferably provided with rollers g.  The finished tube is drawn off by means of the rolling up device h.  If desired, the tube may be cut at the sides to form two bands.  The curve guides are rotatable, and their spread is regulable by the force of a spring device i. Preferably, the spreading arms have the form of a logarithmic curve. In a modification shown in Fig. 2, the flexible tube passes inside a constraining piece 5, and compressed air supplied by a passage 4 passing through the centre of the nozzle, expands the tube to stretch it transversely.  After emerging from the member 5, the tube is pressed flat by two rubber rollers 7, and is then cut at the edges by a device 8 to produce two foils 9 which are rolled up on drums 10.

Title: Moulded graphite bodies for slowing down and reflecting neutrons, and process of making same
Inventor: GREINER HERBERT
IPC: C04B35/532
Filed: 1957-10-01
Abstract: Impermeable moulded bodies, suitable for slowing down and reflecting neutrons in nuclear reactors, have a density above 1.8 g/cc., are composed of pure graphite flakes substantially all arranged parallel, and are substantially free of interstices between the flakes or have the interstices filled with polytetrafluoroethylene or graphitic material.  Orientation of the graphite flakes is effected by dry rolling, magnetic fields, extrusion in admixture with a volatile liquid, e.g. alcohol or ether, in a ratio 1-1.5:1, or by trickling into a gently vibrating mould.  One particular method (Fig. 3 not shown) is to extrude a broad band of graphite/liquid mixture which is folded upon itself in layers concertina-wise, and the fold edges are cut off before inserting in a mould.  The oriented graphite is compressed to above 1.8 g/cc. at pressures from 300 to above 20,000 kg./sq.cm. preferably under subatmospheric pressure, with exclusion of air, while heating to 400-800 DEG C.  Plates, bricks, cubes, cylinders, and tubes may be made, and various combinations of applying pressure in directions perpendicular to, parallel to, and inclined to the layer planes are described to eliminate voids by telescoping the flakes together.  A rotating press die may also be used.  If desired the graphite before compression may be mixed with polytetrafluoroethylene or a carbonaceous binder to ensure that interstices are filled.  When a carbonaceous binder, e.g. coal tar pitch, petroleum tar, asphalt, or starch, is used it is carbonised at 1000-2000 DEG C. after compression and finally graphitised, although additional impregnations may be effected before graphitising.  The graphite which may be 0.01 mm. flakes may be purified by heating to 800-1000 DEG C. in the presence of Cl2, or Na2CO3 before use, and bodies of densities 2.25 g/cc. are stated to be produced.  The resulting body may, as one electrode, be passed to and fro over a carbon antipole plate, while a current of 1000-2000 amps./sq.cm. is applied, in inert gas, e.g. A, N2 or CO, at atmospheric or increased pressure to produce a very dense parallel oriented body.
