Abstract: 867,086. Winding and reeling. UNITED ENGINEERING & FOUNDRY CO. Nov. 26, 1959, No. 40179/59. Class 83 (4). Strip coiling apparatus comprises a reel on which the strip is to be coiled, a plurality of guide-members forming a spaced channel around and adjacent the peripheral surface of the reel through which channel the strip is directed to pass for coiling on the reel, and a plurality of fluid discharge nozzles located around the reel periphery and arranged, when supplied with fluid, to direct fluid under pressure against the strip passing through the channel to force the strip into contact with the reel. Metal strip from pinch rolls 31 is passed between plates 28, 29 and then between a driven reel 11 and a first curved guide 12 closely adjacent the reel periphery. As the leading end of the strip arrives adjacent adjustable nozzles 21 spaced along and around the guide 12, highpressure fluid is expelled from the nozzles to strike the moving strip and force it against the reel 11 to torm a tight first wrap thereon. After sufficient strip has been wound to ensure a tight grip on the reel, the guides 12, together with the nozzle 21, are retracted by fluid pressure cylinders 17. Fluid may continue to be expelled from the nozzles, for cooling, until the coil is completed. Driven or idle rolls 26 may be moved by piston and cylinder means 27 to contact the strip when necessary to force it against the reel. A roll 33 is swung up to support the coil on withdrawal of the guides 12 to their inoperative position.

Title: Improvements in method for preparing sodium aluminium hydride
Inventor: HINCKLEY ALFRED ARMOND
IPC: C01B6/24
Filed: 1957-12-30
Abstract: In preparing sodium aluminium hydride by reacting an aluminium chloride and sodium hydride in tetrahydrofuran, the aluminium chloride is used in the form of an etherate of diethyl ether, and the NaH is prepared by hydriding a dispersion of Na metal in an inert liquid hydrocarbon.  The Na metal is agitated in the liquid hydrocarbon at 200-350 DEG  C. under atmospheric or super-atmospheric pressure in the presence of hydrogen, and agitation is continued until hydrogen absorption ceases.  The NaH, as a dispersion in the hydrocarbon, or after separation therefrom, is placed in a vessel, tetrahydrofuran is added, followed by the aluminium chloride etherate.  The reaction may be effected in an inert atmosphere, e.g. nitrogen, and some NaAlH4 may be included as seed.  The precipitated sodium halide and excess NaH may be centrifuged off, the tetrahydrofuran and diethyl ether are removed by distillation, and the NaAlH4 precipitates from the hydrocarbon.

IPC: H01L49/02
Filed: 1966-09-19
Abstract: 1,191,277. Printed circuit resistors and capacitors. PLESSEY CO. Ltd. 1 Sept., 1967 [19 Sept., 1966], No. 41745/66. Headings H1M, H1R and H1S. In a thin film printed circuit the resistance value of resistors, formed by vapour deposition on a glass substrate, are arranged to be initially lower than the required value and then the values are adjusted within limits of tolerance by scribing an incision. For example, in Fig. 1, a resistance value of 1000# is required. A resistor 11 is therefore connected to probes 32, 33 (Fig. 3) of a measuring bridge 31 which is adjusted so that the bridge will be balanced when the resistor 14 is 990# to an accuracy of 0À1%. The unbalance output energizes a servomotor 35 (Fig. 3) which moves a scribe 38 to make an incision 14 in the resistor 11 which increases the resistance value until the bridge is substantially nulled. A second resistor 15 having a nominal value of 8# is provided in series with R 11. The resistance of R11 is then measured to an accuracy of 0À01% and the required value of R15, to make the series combination 1000#, is calculated. R15 is then connected in the bridge circuit which is set to the calculated required value and an incision 17 is made as described above, an overall accuracy of 0À011% thus being obtained. Alternatively the resistors may be connected in parallel (Fig. 2, not shown), or the adjusting device may be applied to capacitors.

Abstract: 1,193,324. Automatic volume control. ERESA S.A. 19 Sept., 1967 [29 Sept., 1966], No. 42636/67. Heading H4R. In an a.g.c. system in which signals above a predetermined level give rise to a control current which is fed to a variable attenuator to reduce the signal level, the control current is fed to the variable attenuator via an integrating network so that when the signal level falls below the predetermined level the control current is maintained for a time dependent on the length of time the predetermined level was exceeded. In Fig. 3 a signal is fed via terminal Ue to the attenuating network 8 which delivers an attenuated output from terminal Usa, the attenuation of the network depending on the control current Ic which varies the impedances of the diodes 13, 13a, 14 and 14a. The control current is derived from the amplified output of the attenuator which is rectified in 17. Signals above the predetermined level cause Zener diodes 18, 18a to conduct and feed a control current Ic to the attenuator network via the forwardly conducting diodes 18, 18a. While control current flows from bridge rectifier 17 capacitors 22 and 25 charge up via resistors 24 and 27. When the signal level Us falls and Zener diodes 18, 18a, cease to conduct the control current Ic continues to flow, supplied from capacitors 22 and 25 via forwardly conducting diodes 23 and 26, for a time dependent, on the charge in these capacitors and hence the length of time that the signal level Us exceeded the predetermined level. As described capacitor 21 has a discharge time constant of 60 m. sees., capacitor 22 a discharge time constant of 0À4 to 2À5 secs., and capacitor 25 as discharge time constant of 3À0 to 7 sees.
