Title: Vehicle speed controls
IPC: G05D13/62
Filed: 1975-07-17
Abstract: 1486530 Automatic control of speed DANA CORP 17 July 1975 [24 July 1974] 30005/75 Heading G3R In an automatic speed control system for a vehicle, a dead band is provided in the control to minimize atmospheric bleed to the vehicle manifold and in this dead band a speed control vacuum bellows does not communicate with a vacuum source or atmosphere. As shown, the dead band forms maximum and minimum speed reference signals V 2 , V 1  that are compared with the actual vehicle speed to control valves 110, 114. If the actual value is greater than the maximum V2, bellows 100 Fig. 1 (not shown), linked to the vehicle throttle, are connected by valve 110 to engine manifold vacuum, and if less than the minimum value V 1  are connected by valve 114 to atmosphere. If however the actual value is within the dead band, both valves remian deenergized. The actual vehicle speed signal is determined using a vehicle engine driven switch S 1  to form pulses at a frequency proportional to vehicle speed, which are integrated by R 14  C 6  to produce a speed dependent voltage. This voltage may be modified according to the measured position of the vehicle throttle, to reduce overshoot of the control; In alternatives, the dead band can be provided in the comparator or applied to the actual vehicle speed signal Fig. 3 (not shown). The system may be disengaged manually, when the brakes are applied or when the actual speed is substantially lower than the reference value.

IPC: C25C1/10
Filed: 1964-07-28
Abstract: Pure chromium is continuously cathodically electrodeposited from an aqueous solution of chromium trioxide (chromic acid) in the presence of fluosilicic or hydrofluoric acid to which is added at a rate corresponding to that of chromium deposition a solid pure hydrated chromic oxide obtained by reducing a solution of sulphate-free alkali chromate or dichromate with an organic reducing agent at an elevated temperature in an autoclave and filtering off the resulting chromic oxide.  As described pure hydrated chromic oxide so produced is added to a bath containing per litre 100 g. CrO3 and 6 g. H2SiF6 in a lead vessel as anode containing a 1 cm. diameter steel rod as cathode and electrolysis is effected at 80 DEG C. with a current of 20 amps. at 4 volts to oxidize the chromic oxide to give a bath having hexavalent Cr content of 156 g/1.  Part of this bath is used in the production of the chromic oxide to remove its alkali content and to the remainder is added a further 6 g/1 of H2SiF6 to form the initial chromium electrodeposition bath, electrodeposition of chromium then being effected at 95 DEG C. with a cathode current density of 100 amps/dm2 at 4 volts and chromic oxide being continuously added.ALSO:Pure hydrated chromic oxide consisting of .71 to 75%.Cr2O3 .0.05%.Na2O .\sT0.005%.Fe2O3 .\sT0.002%.S .remainder.water is prepared by  (i) dissolving commercial sodium dichromate containing 0.3% S in water and bringing pH to 2 with HCl,  (ii) precipitating sulphate cone with BaCl2 removing 99% of the sulphur,  (iii) heating the filtrate with wood meal in a sealed autoclave at 250 DEG  C. with stirring to yield a granular hydrated brilliant green oxide,  (iv) washing until alkalinity is no longer detectable, and  (v) removing alkali metal content by treatment with sulphate-free chromic acid solution.  The chromic acid solution may be obtained by electrolytic oxidation of pure hydrated chromic oxide in a chromic acid-fluosilicic acid bath.

Patent GB-762190-A (GB)
Title: Improved spinning process
Inventor: BARRETT PETER THOMAS
IPC: D01D11/00
Filed: 1953-11-03
Abstract: <PICT:0762190/IV(a)/1> The uniformity of continuous filaments produced by spinning is tested by determining the bi-refringence of the filament and adjusting the spinning conditions to compensate for variation on bi-refringence.  The invention is based on the fact that the tenacity of the drawn filaments is related to the bi-refringence. In the arrangement shown in Fig. 3, light from a mercury arc lamp 4, modulated at 100 cycles/sec passes through a red filter 5, is polarized by a Nicol prism 6 and falls on a filament 7 of polyethylene terephthalate at 45 DEG  to the plane of polarization. The light then passes through a crossed Nicol and is received on an eleven-stage photo-multiplier 9 and recorded by an A.C. voltmeter 10. Under these conditions the output of the voltmeter representing the intensity of the transmitted light is a function of the bi-refringence.  The Specification states that when the threads are made by forcing a melt through small orifices in a spinneret by a gear pump and leading away the filaments by a wind-up device the bi-refringence may be changed by altering the feed of the wind-up device.  The gear pump must also be speeded up, however, to maintain the diameter of the thread contacts.  In another method of detecting the changes of bi-refringence monochromatic sodium light is polarized by a Nicol prism.  The polarized light is scattered by a scattering plate and after passing through a quarter-wave plate is analysed by a rotatable Nicol.  The light emerging from the analyser is received on a light sensitive device and the analyser is rotated until the output of the device is a minimum.  A ribbon of filaments of polyethylene tetraphthalate then replaces the scatter plate and the extinction angle of the analyzer is measured.  A comparison of the two values indicates the bi-refringence of the threads.  The light-sensitive device may be replaced by a microscope and the extinction position determined visually.
