Title: The manufacture and production of hollow filaments from solutions of cellulose derivatives
IPC: D01F2/30
Filed: 1930-03-19
Abstract: Hollow artificial filaments are produced by dryspinning solutions of cellulose derivatives such as cellulose esters or ethers, using spinning dies the holes of which are of conical shape and taper to a greater diameter on the outside face of the die.  Suitable dimensions of the dies are 0,05-0,07 mm. in diameter on the inside and 0,09-0,11 mm. on the outside, the thickness of the metal being from 0,4-0,5 mm. The temperature of the gaseous atmosphere in the spinning chamber varies according to the denier of the filament to be spun and according to the spinning speed, the temperature being higher when spinning a filament of high denier and when using a high spinning speed; for example, filaments of about 5 denier being spun at about 70-110 metres per minute require a temperature of about 75-100 DEG C. The temperature of the spinning solution is in all cases somewhat lower than that of the evaporative medium.  A preferred spinning solution comprises a 12-35 per cent solution of cellulose acetate dissolved in acetone, with or without the addition of diluents such as water or alcohol.  In the following examples, spinning dies of dimensions within the above specified limits are used-(1) Yarn of 100 denier with 20 filaments is spun at the rate of 110 metres per minute from a 23,5 per cent solution of cellulose acetate in acetone, the solution temperature being 55-57 DEG  C., and the cabinet temperature 100 DEG  C., the amount of air passing through the cabinet being 5,5 cubic feet per minute. (2) A 32,5 per cent solution of cellulose acetate is spun to give yarn of 140 denier with 20 filaments at a speed of 90 metres per minute.  The temperature of the solution is 50 DEG  C., and the evaporative atmosphere, which is passed at the rate of 5 cubic feet per minute, 85 DEG  C.

Title: Improvements relating to electromagnetic pick-offs
Inventor: BOURNE ALFRED JOHN
IPC: G05D3/14
Filed: 1954-03-30
Abstract: 800,131. Electric transducers. FERRANTI, Ltd. March 24, 1955 [March 30, 1954], No. 9216/54. Class 40 (1). An electro-magnetic pick-off is of the type having two members of magnetic material designed for relative movement in either a plane or on part of the surface of an imaginary sphere, and defining between them four magnetic circuits each having a pick-off winding individual to it so that movement of one member relative to the other affects the relative values of the reluctances of the four magnetic circuits. The fixed member 10, Fig. 1, carries all the windings and may include an inner limb 12 carrying a primary winding, the centre line 13 of which limb 12 is aligned on a point about which the member 11 may swing in two dimensions. The limbs are joined by a yoke 19 and are provided with part-spherical pole faces which are complementary to the lower face of the member 11. In operation, when the member 11 is directly above the pole faces of the limbs the reluctances of all four magnetic circuits are equal. If member 11 now moves slightly, Fig. 3, the reluctance values will be altered and a correcting error signal developed. Similarly a signal will be developed when member 11 moves in the opposite direction. In a modification the wound member may move, or both members may move, and the members may be curved otherwise than in Fig. 1 or be flat. Where the pick-off includes a primary winding as in Fig. 1 then the four other windings are connected in series opposed pairs, but where no primary is included the four windings are in series-opposed pairs as before and each pair is connected with two resistors as a bridge, the signal in respect of each pair being taken between the common point of the two windings and the common point of the two resistors whilst the supply voltage is applied across the other two points of the bridge.

Abstract: 566,776. Electroplating. LANE, M. S. June 9, 1943, No. 9271. [Class 41] Metal is electrodeposited on a cracked or disfigured area of a metal article, such as a casting, by arranging the article with the surface of the part to be treated uppermost, applying thereto an upstanding encircling wall of thermoplastic material such as pitch, preferably with a stopoff layer intervening, heating the junction of the wall and surface to form a liquid - tight joint and provide a cell 10 which is filled with electrolyte suitable for effecting the deposition, the cell containing an anode 12 and the article being made the cathode. The surface to be treated may be given an anodic etching in an acid bath and an initial grinding or scouring treatment, and if a gaping crack 11 is present, this may be filled with dental plaster which is non-conducting or inert to the etching bath ; after etching, the cell is washed out and plating baths introduced to produce in turn deposits of nickel and copper in the case of a cast-iron surface. For the plating, the plaster is rendered conducting or replaced by an electrically conducting filling and the sequence of operations repeated, the final plating with copper being at this stage continued for four or five days. Cracked valve seatings are plated with nickel only. The metal deposited may be inset in the cracks by widening them to form undercut grooves.

Filed: 1936-03-28
Abstract: 472,689. Turning-gear. ECLIPSE MACHINE CO. March 28, 1936, No. 9275. Convention date, March 30, 1935. [Class 7 (v)] In an engine-starter drive of the type in which the meshing of a pinion 5 with an engine gear 6 is controlled manually and the demeshing is effected automatically when the engine starts, a positive locking means 42 holds the pinion in mesh with the gear 6 until the engine starts and is released in response to the speed of rotation of the pinion. As shown, the pinion 5 is freely journalled on the starting-motor shaft 2 and is rigidly connected to a barrel 7 and a driven clutch member 9 in the end of the barrel. A threaded sleeve 3 is splined to slide on the shaft 2 and a nut 19 threaded on the sleeve has a conical surface normally held by a spring 27 in light frictional with a surface 22 of the clutch member 9. A stop and clutch member 23 fixed on the end of the sleeve 3 has a conical surface for engagement contact with a surface 26 of the member 9. The locking means 42 consists of spring-pressed radial detents carried by the barrel 7. The sleeve 3 is moved axially to engage the pinion 5 with the engine gear 6, by means of a lever 31 actuated by a pedal and connected by linkage 41 to a starting switch 39. When the pinion is almost fully in mesh and the switch 39 is closed, rotation of the shaft 2 and sleeve 3 advances the clutch member 19 and the barrel 7 to the left, forcing the detents 42 over the shoulder 43 into locking engagement with the end face of the clutch member 23, and wedging together the clutch members 9, 19, 23 to transmit torque to the pinion 5. When the engine starts, the clutch member 19 returns on the threaded sleeve, and the detents 42 are withdrawn by centrifugal action on sufficient speed being reached, whereupon the barrel 7 is moved to the right by the spring 27 to demesh the pinion. This movement is limited by a stop 40. On the release of the lever 31, the sleeve 3 threads itself through the clutch element 19, movement of the barrel 7 being prevented by a bracket 47 engaged by a ring 16 on the barrel.

In an axial-flow, elastic-fluid turbine, stationary shroud means surrounding the tips of the rotor blades is supported from the outer periphery of the stator blading whereby it may expand and contract independently of the turbine casing, the stator blading being supported by a diaphragm structure and arrangements being provided for circulating cooling fluid about the diaphragm structure. The gasturbine shown in Fig. 1 comprises a rotor disc 1 carrying rotor blades 16, the rotor blades being surrounded by a stationary shroud ring 17 which is supported from the stator blades 2. The stator blades 2 are formed at their inner and outer ends with platforms 7, 11 respectively, the platforms being formed with radiallyprojecting flanges 8, 12 respectively. The flanges 8 are supported by means of bolts 9 in a recess 6 in the diaphragm 3, the diaphragm being located at its inner periphery upon the housing 4 of a bearing in which the rotor shaft 5 is mounted. The flanges 12 on the outer platforms 11 bear against a face 13 extending inwardly from the stator casing 15, and the stator shroud ring 17 which is in the form of segments is attached to the flanges 12; alternatively the segments of the shroud ring may be formed integrally with the flanges 12 or with the platforms 11. A sheet metal member 18 is secured to the upstream side of the diaphragm 3 to provide a, passage for the flow of cooling air. In Fig.,2, the stator shroud ring 23 surrounding a row of rotor blades mounted on a rotor 22 is secured in recesses formed in the outer platforms 27 of stator blades 21 disposed on either side of the rotor blade row by means of keep members 25 secured by riveting to the outer surface of the shroud ring and which engage the projections 24 of the platforms 27. The stator blades are supported on the diaphragms 30 and have flanges bearing against the stator casing as in the first embodiment. A pair of sheet metal members may be disposed adjacent the upstream and downstream faces of the diaphragm (Fig. 3, not shown), cooling air being admitted from the rotor into the space between the pair of members at the upstream side of the disc, the cooling air flowing radially outwardly through this space, then radially inwardly through the space between the inner sheet metal member and the upstream face of the diaphragm. The cooling air then flows through apertures in the diaphragm and radially outwardly adjacent the downstream face of the diaphragm, finally discharging into the working fluid stream.
