Filed: 1959-01-27
Abstract: 853,789. Projectiles and self-propelled missiles and fuzes therefor. HOTCHKISS-BRANDT. Jan. 27, 1959 [Feb. 3, 1958], No. 2871/59. Classes 9(1) and 9(2). Relates to a self-propelled missile launched by an auxiliary charge separated from the propellent charge proper by an obturator P containing a fuze as in Specification 768,295, the fuze consisting of two parts, one behind the other, the rear part being a compressed powder, which withstands high launching pressures and is not completely consumed until the missile leaves the launching tube and the forward part having a passage containing a compressed powder which burns after the missile leaves the launcher. A finned tail Q receives a tube R containing the launching charge S as in Specification 834,969. The obturator P, which is held in position by a shear ring 16 and a clamping ring 17, has a body 14 with an axial bore housing the fuze components. The bore ends at a concave wall 22 through which extend passages 23, which can be closed by rotation of an apertured disc 25. The disc is provided with a rib 27 which is engaged in the tube R, so that by rotating the tube the disc is adjusted. The rear element V of the fuze is held against a shoulder 20 in the bore by screwing in the forward element W. The element V has a body 28 of a plastic material such as a superpolyamide and bears against a sealing ring 29. Flash from the launching charge S is conveyed to the time fuze charge 30 in the body 28 by powder 24 in the passages 23 and cavity 21, the rate of propagation depending on the degree of opening of the apertures. An auxiliary relay charge 32 is pressed into a blind hole in the wall 22. The element W is a cylindrical metal block, Figs. 5 and 8, with an annular recess (35, 36) in each end face, each recess being interrupted by a metal plug (37, 38). An inclined bore 39 leads from recess 36 to the centre of the opposite end face and a parallel bore 40 leads from recess 35 to the centre of the first end face. A bore 41 parallel to the axis of element W provides direct communication between the recesses. Compressed black powder fills the bores and recesses. The device P is closed by a relay 42 having a flange 45 cold-welded to the body 14 and housing an igniter 43 and loose powder 44. Over the powder, a disc 46 is welded to the relay, which extends into the flash tube 9 of the missile propellant. By manipulating the disc 25 to close the passages 23, the missile can be fired as a projectile by means of charge S. If the disc 25 is adjusted to uncover the passages, flash from the charge S ignites the powder 24, which in turn ignites the fuze 30. Fuze 30 ignites the black powder in element W at a and the combustion proceeds from a to b along groove 36 and through bore 41 to groove 35 whence it travels through bore 40 to h to fire the igniter 43. Relay 43 ignites the powder 44 and the flash passes through tube 9 to ignite a primer 8 for the propellant as in Specification 768,295, the device P being ejected by the gas pressure.

Abstract: 994,786. Electric correspondence control systems. BELL & HOWELL CO. Aug. 4, 1961 [Aug. 8, 1960], No. 28373/61. Heading G1N. The position of a tool relative to a workpiece is measured by coarse and fine devices, the latter comprising a nut on a measuring screw, whose position within one screw pitch is determined by comparing the capacitance between each side of the nut and the corresponding sides of the screw thread, the resulting signal being used to displace the nut and the tool, using a magnetostrictive transducer. As shown (Figs. 1, 2), a workpiece 26 is mounted on a carriage 22 for movement along a screw 21 by motor 20. Whilst being rotated by motor 25. The tool 46 mounted on its carriage 44 is moved along its drive screw 31 by a motor 32 acting through a drive nut 41. The carriage 44 is attached to a measuring nut 45 located on a measuring screw 47 rigidly coupled to the drive screw 31. The two sides of the nut 45 form a differential capacitor with the thread of the screw 47, these capacitances being compared is a bridge circuit 49 whose output is amplified, phase-rectified and fed through a trigger circuit 92 to the winding 107 of a magnetostrictive rod 43 coupling the tool carriage 44 to the drive nut 41, whereby the measuring nut 45 and tool 46 are accurately positioned on screw 47 by the subsequent extension of rod 43. The trigger circuit 92 predetermines the minimum value of error signal to produce adjustment, and diode 197 ensures that this is only effected for signals of one polarity. The drive motors 20, 32 may be controlled by a digital control system. In another embodiment (Fig. 5) the tool drive screw 151 and measuring screw 153 are arranged side by side, coupled through a gear train 154, and a magnetostrictive rod 162 couples the tool carriage 157 to the drive nut 155. In a modification (Fig. 8), a crank 172 rotates the drive screw 171 and also the measuring screw 177 through gears 180-183, a magnetostrictive rod producing additional rotation of the measuring screw when energized as above, by appropriate angular movement in the gear train. The position of tool carriage 175 is indicated by coarse indication of a pointer 186 on a scale 186, and fine indication of a dial 184 fixed to measuring screw 177 co-operating with a stationary vernier 185. Specification 994,785 is referred to.

Title: Improved method for the treatment of freshly-spun artificial threads with liquids in a continuous process
IPC: D01D10/04
Filed: 1946-01-30
Abstract: Freshly spun artificial threads are caused to spread in treatment baths wherein they are treated with liquids in a continuous process by being led by means of guide-rolls through a series of vats, one or more of the guide-rolls being situated above the vats and being preferably grooved and being driven and the other rolls being mounted freely in the vats, characterised in that the driven roll appertaining to the first vat and being situated either outside the vat or at the beginning of the bath run is driven at a greater speed than the following top-rolls, all of the latter being driven at the same speed.  In an example, in a bath-run of 45 cm. in each bath, a sufficient thread-spreading is obtained in all the baths if the circumferential speed of the first driven grooved roll, whence the threads run into the bath at a speed of 60 metres per minute be about 1 per cent higher than the circumferential speed of the driven rolls appertaining to the other baths.  Specification 311,399, [Class 2 (ii)], is referred to.
