Abstract: 1293851 Crimpable polypropylene fibres MITSUI PETROCHEMICAL INDUSTRIES Ltd 28 Jan 1970 [28 Jan 1969] 4204/70 Heading B5B [Also in Division C3] Composite filaments which are crimped or which become crimped when heated in the relaxed condition are made by simultaneously melt extruding polymeric components which have different thermal shrinkage characteristics at temperatures below the melting temperatures of the polymeric components to produce composite filaments in which the different portions are arranged in side-by-side relation or in eccentric core-and-sheath relation and the filaments are then stretched. The process is characterized in that a molten composition is prepared comprising (a) a propylene polymer containing at least 90 mole per cent of units derived from propylene and (b) 0À05% to 5% by weight of one or more phosphorus compounds of the formula wherein each of R, R<SP>1</SP> and R<SP>11</SP>, which may be the same or different, represents an hydrogen atom or an alkyl (including aralkyl) group containing at least 6 carbon atoms, subject to the proviso that at least two of R, R<SP>1</SP> and R<SP>11</SP> represent such alkyl groups; each of Y and Y<SP>1</SP>, which may be the same or different, represents an oxygen or a sulphur atom; n is 0 or 1. Conventional stabilizers may also be present. Different portions of the molten composition are subjected to heat treatments which differ in time and/or temperature and said different portions are simultaneously melt-extruded through an extrusion orifice of a spinneret to produce a composite filament in which the different portions are arranged in side-by-side relation or in eccentric core-and-sheath relation. The composite filament thus produced is stretched. Two separate streams of the molten composition may be subjected to different heat treatments and the temperature (T 1 ) and time (t 1 ) of the heat treatment of the first stream and the temperature (T 2 ) and time (t 2 ) of the heat treatment of the second stream may be such that T 1  - T 2  is not more than 100; t 1 /t 2  is not more than 30; and log t 1 /t 2  is not less than [- 0À01477(T 1 -T 2 ) + 0À0738], temperatures being expressed in C. and times in minutes. The propylene polymer may have an intrinsic viscosity (measured in decalin at 135 C.) of 0À5 to 3À0 and an isotactic index of at least 80. The filaments may be stretched at a draw ratio of 2 : 1 to 10 : 1 at a temperature of 60 to 150 C. After having been stretched the filaments may be heated to a temperature within the range 90 to 180 C. while in the relaxed state.

Abstract: 629,627. Forging-machines; dies. SALES, W. A. Feb. 14, 1947, No. 4372. [Class 83 (iv)] Making turbine blades.-Metal is forged in a die of refractory ceramic material by subjecting it to a relatively steady pressure while it or part of it is at a temperature at which it is in a plastic state. The dies may be formed from clays, silica, magnesite, dolomite, alumina, chromites, and in particular berrylia, zirconia, thoria, sillimanite and boron. In one form a die 11, 1<SP>11</SP>, split on a horizontal plane, is carried in steel covers 3<SP>1</SP>, 3<SP>11</SP> and mounted in a press, the upper cover 3<SP>1</SP> and die half 1<SP>1</SP> being vertically movable by the ram 2 of the press. A bar or partly preformed slug 4 extends through the die 1<SP>1</SP>, 1<SP>11</SP> and is held at each end by a split electrode 9, normally held closed by compression springs 10. In operation the upper die and electrode halves 1<SP>1</SP>, 9, are raised by the ram 2 and the work-piece 4 placed on the lower electrode halves, which are raised proud of the lower die half 1<SP>11</SP> by the springs 10, the upper die half 1<SP>1</SP> is lowered until the upper electrode halves grip the bar and electric current is switched on to heat the bar to a plastic state. The die-halves 1<SP>1</SP>, 1<SP>11</SP> are then brought firmly together and endwise pressure applied at each end, preferably by hydraulic rams, until the metal within the die upsets to fill cavities 8. Some preliminary forming may take place when the die-halves are brought together. In a modification, Figs. 3 and 4, (not shown), described as applied to the manufacture of turbine blades, the metal is forced into the die cavity by pressure applied to the upper die half, surplus metal being squeezed out and into a gap between the die halves, forming a flash which is subsequently removed. The current may be switched on and off during forming to control the temperature, and heating may be effected by either highfrequency induction or resistance heating, or a combination of both. The process may be performed under controlled atmosphere conditions to prevent scaling. In a modification, pre-heated bars or slugs may be used without recourse to electric heating to maintain the temperature.

Title: Improvements in automatic voltage regulators
IPC: G05F1/42
Filed: 1956-02-14
Abstract: 811,017. Automatic voltage control systems. FOSTER TRANSFORMERS Ltd., and THOMAS, P. G. Feb. 8, 1957 [Feb. 14, 1956], No. 4566/56. Class 38 (4). An automatic voltage regulator consists of a buck/boost transformer T2 energized by a variable output transformer T1, the connections to transformer T2 being reversed in sense at the low limit of transformer T1 so as to double the range of regulation by changing from buck to boost or vice versa. The variable output transformer T2 is energized from the output terminals O of the regulated A.C. supply, and the output tapping is controlled by a reversible 2-phase servomotor 1. The motor 1 has a reference field 2 and a control field 3 fed from an auxiliary A.C. source, the supply to the control field 3 being reversible in sense by a centretapped supply transformer T3 and a pair of switching thyratrons 4, 5 which are selectively fired according to whether the output voltage of the regulator is high or low (by undisclosed apparatus). If, for example, the voltage is high, valve 4 conducts and motor 1 drives the transformer T1 towards minimum to reduce the boost voltage. At minimum, limit switch S1 is closed thereby energizing relay S5 which holds in over contacts S53 and changes over contacts S51 and S52 thereby reversing the sense of the supply to transformer T2 and reversing the direction of motor 1 so that continuing conduction of valve 4 results in an increasing bucking voltage. If the " raise voltage " valve 5 conducts, then relay S3 is energized to prepare a path over contacts S31 to short out and release relay S5 when the limit switch S1 is closed thereby restoring the original " boost '' connections.

[Class 54.] In a gas-holder having the water or other sealing liquid within the holder covered with oil, the passage of the oil to the exterior of the holder is prevented by maintaining the level of the sealing liquid in the cup and grip during the operation of uncupping substantially above the bottom of the inner wall of the grip. In Fig. 10 this is effected by maintaining the level of the sealing liquid in the space 6 between the inner wall 5 of the grip and the holder wall 7 equal to that of the liquid in the main tank 8 by means of an automatic syphon. This syphon may comprise an inverted U-pipe 9 having an upturned inlet 9a and fitted with a valve 11 to prevent syphoning backwards. The necessary vacuum to fill the syphon may be created by a projection 14 on the wall 7 operating a lever 13 as the holder moves downwards to raise a plunger 12 in a chamber 12a connected through an air bottle 10 to the upper part of the U-pipe 9. In Fig. 12 the gas in the space 3 between the cup and grip is allowed to escape to the outlet main past a valve 16 which may be operated electrically or by a cam 17 on the wall 7. Instead of the valve 16 an electrically or mechanically operated pump may withdraw gas from the space 3.
