Title: Hot stretching and relaxing polyester yarns
IPC: B29D30/40
Filed: 1970-04-02
Abstract: 1,261,337. Hot stretching and relaxing polyester yarns. CELANESE CORP. 2 April, 1970 [12 May, 1969], No. 15675/70. Heading B5B. Filamentary polyester yarn, wherein the polyester is composed of at least 85% by weight of a polymeric ester of a dihydric alcohol and terephthalic acid is hot stretched by at last 8% and then hot-relaxed at least 7%, based on the original length of the yarn at a temperature lower than any used in stretching it and between 325‹ F. and 400‹ F., the net change in length being not more than 2% of the original length. In accordance with these conditions the yarn may be stretched by from 8 to 16% and relaxed by from 7 to 14%. The yarn may be stretched at temperatures of from 390‹ to 490‹ F. The yarn may be passed through two or more heating zones at successively higher temperatures before relaxation, stretching being effected in at least one of the zones and the yarn being maintained under sufficient tension to prevent it from shrinking in the zone(s) wherein stretching is not being effected. A composition for securing adhesion of the yarn to rubber may be applied to the yarn and dried thereon before the yarn is hot stretched. The yarn may be composed of filaments consisting of polyethylene terephthalate having an intrinsic viscosity of between 0À7 and 1À5 decilitres/gram (as measured in o-chlorophenol at 25‹ C. The term " yarn " is defined as including mono-filaments and multi-filament bundles with or without twist, but excluding spun staple fibre yarn. By means of the invention yarns can be obtained which can be further processed at temperatures at least up to the relaxation temperature used with negligible, if any, decrease in strength, while yarns treated under standard conditions lose 12 to 15% of their strength at temperatures reached during rubber-curing operations.

Title: Amplifier employing broad band tuned circuit
Inventor: SMITH HENRY RICHARD
IPC: H03H7/01
Filed: 1955-06-01
Abstract: 773,720. Discharge tube amplifying circuits. STANDARD ELECTRONICS CORPORATION. June 1, 1955, No. 15701/55. Class 40(6) In a broad band amplifier, a discharge tube 29, Fig. 1, is supported in the upper end of a primary co-axial line 10, 11 coupled to a, secondary co-axial line 12, 13 the lines being tuned by ganged shorting rings 16, 17, 18 to which is attached a coupling member 19. Output is taken from the secondary co-axial line over adjustable capacitor 67, 68 and transmission line 64, 66. The shorting rings are raised and lowered by means of screws 27, Fig. 2, engaging screwed hubs 26<SP>1</SP> rotated by chain 25<SP>1</SP> from shaft 24. The metal coupling bar 19 is held at a distance from the ring 16 by a captive screw 21 adjustable through openings 23. The bars 16, 19 extend through a longitudinal aperture 15 in the wall between the primary and secondary line. The anode 30 is held by fingers in the tube 31 which is spaced by insulators 36, 37, 38 from the inner conductor 11 so that cooling air is drawn through the anode. Air flow through opening 58 is limited by sheet 59 so that air passes through the opening 55 and over the grid seal of the tube 29. The H.T. supply is passed through a bush 32 and shaft 33 to contact 35. Flexible grid leads 42 contact a ring 41 which forms with plate 40 a capacitor to allow the application of grid bias while maintaining the grid at earth potential for R.F. The input signal is applied to the filament terminals 44 which are maintained at the same R.F. potential by capacitor 48. The outer cover 50 may be rotated about hinge 51 and the plate 40 about hinge 49 to allow replacement of the tube 29. A neutralizing stub 60 provides a small amount of feed back from anode to filament. A tube 71 operating as an inductor forms with the capacitor ,72, 74 a combination which is the equivalent of the series grid inductance and the grid to anode capacitance thus, allowing the primary and second lines to be ganged. The movable. plate 74 of the capacitor has a flange 75 with contact fingers 76 and is raised and lowered by means of a control shaft 81 engaging a threaded block 80. The equivalent circuit is shown in Fig. 5 where L is the series grid inductance of tube 29 and capacitor C1 the grid to anode capacitance of tube 29.

Title: Improvements in or relating to Gyro-compasses.
Inventor: BROWN SIDNEY GEORGE
IPC: G01C19/38
Filed: 1917-10-30
Abstract: 124,533. Brown, S. G. Oct. 30, 1917. Gyro-compasses.-Relates to the type of gyrocompass described in Specification 124,529 in which the pendulous or gravitational factor controls the gyroscope through an intermediate and separate source of power, such as an air-blast derived from the air in the gyro casing and differentially controlled to displace mass (e.g. liquid containers in a pair of inter-communicating vessels) from one side to the other of the axis of the casing. In the constructions described in the said prior Specification, the gravity control was affected through a small pendulum device mounted on the gyro casing. According to the present invention, the relay or intermediate source of power effecting the orientation of the compass is controlled by the pendulous mounting of the gyroscope itself. In the construction shown in Fig. 1, the air-blast from the casing A is led into an air-box D with pipes d leading to the liquid-containing vessels and is controlled by a plate E secured to the orienting frames B, in which the gyro casing A is mounted on knife-edges a. The vertical axles b, b<1> of the frame B are mounted as described in Specification 22379/14. In the construction shown in plan in Fig. 4, the airblast from the nozzle C is directed into the air-. box D by a conical nozzle E<1> carried by the orienting frame. A further modification comprises an axial tube on the casing projecting into a box mounted on the orienting frame and provided with an upwardly-directed nozzle differentially directing the air-blast into the ends of a pair of tubes connected to the liquid-containing vessels ; this device is described in Specification 124,845, [Class 40 (i). Electric signalling systems &c.].

Abstract: 1,158,760. Felt nib pens. POLYMER CORP. 7 April, 1967 [8 April, 1966], No. 15999/67. Heading A4K [Also in Division B5] The reservoir filling and the writing tip of a felt nib pen are formed of finely chopped fibres, bonded together by sintering. Preferably, the fibres are of natural cellulose, coated with heat fusible material, such as polythene. The pens may be made singly, by pouring chopped fibres into a glass tube having an aluminium foil extension and forming the foil, by pressure, into a tapered writing tip, thus compressing the fibres in this region. The pen is subsequently heated to effect sintering. In a continuous process, the chopped fibres are fed to a strip of aluminium foil, coated with polythene, as it is being coiled spirally to form a tube. The strip is wound so that the edges overlap and the polythene may be fused to form a rigid cylindrical wall. This is swaged or crimped at intervals, before sintering, so that the tube may finally be severed at these positions to form writing tips. The fibres, may, alternatively, be blown into a porous inner tube by compressed air.
