Title: Improvements in or relating to methods and apparatus for carrying out processes for the treatment of objects and materials employing electric glow discharges
IPC: C23C14/32
Filed: 1951-08-01
Abstract: A method of treating objects and materials, e.g. nitriding steel, with an electric glow discharge comprises periodically varying the electrical energy supply and for the atmosphere in which the discharge takes place, selecting the nature of the variation to be made-for example the current and/or voltage of the supply or the pressure and/or nature of the atmosphere, and regulating the duration of a complete cycle of variation and the duration of the portion of the cycle during which the treatment is fully effective.  In one embodiment the voltage and/or current can be supplied in the form of pulses, the duration of the interval being at least equal to the duration of the pulse, i.e. the fully effective portion of the cycle, which may be from 0,1 to 10 secs.  The pulses of voltage and current can be produced by periodically interrupting, by means of rotating contact discs and cam discs operating switches, the electrical power delivered from a dynamo, mercury vapour rectifier, dry rectifier or contact rectifier, or by using thyratrons or ignitrons.  In another embodiment which can be used either separately or in conjunction with the first embodiment the atmosphere is periodically varied by allowing the pressure to pulsate by means of a needle valve being periodically opened or closed by automatic devices.  The pulsation period can be of the order of magnitude of minutes.  Quantities of rare gases such as argon can be introduced rhythmically between the pulses and it is not essential to replace the whole of the atmosphere such as hydrogen, ammonia, metallic vapours, &c., by other gases, vapours or mixtures thereof between the pulses of pressure.  The progress of the treatment, e.g. the temperature of the object being treated, can be used to automatically vary the electrical energy supply or the pressure or composition of the atmosphere.  In a specific example nitriding of steel was effective in 15 hours in an atmosphere of ammonia at a pressure of 6-15 mms., using a glow discharge consisting of 550 volt pulses having a duration of 0,1-0,2 secs with intervals of 0,4-1,4 secs at a voltage of 350, with alternate specific loadings of 2-20 watts per sq. cm., to form a nitrided layer of 0,4 to 0,5 mm. thick.  The diffusion of gases into the surface of chromium plated upon steel, the degassing of metals, and the separating out of impurities such as sulphur and phosphorus is referred to.

Title: Improvements in or relating to the manufacture of paraoxymetanitrophenylarsinic acid
IPC: C07F9/74
Filed: 1923-07-18
Abstract: p-Oxy-m-nitrophenylarsinic acid is prepared by nitrating and diazotizing arsanilic acid in the same solution.  The nitration may be simultaneous with or subsequent to the diazotization. Preferably nitric acid is used in sufficient quantity both to effect nitration and to liberate nitrous acid from the nitrite used for diazotization, but any other acid may be employed for the latter purpose.  The product may be purified by conversion into a salt and recovery of the acid therefrom.  According to the examples, (1) sodium nitrite is added to a mixture of arsanilic acid and nitric acid; after standing a short time, the whole is heated and then allowed to cool for separation of the product; (2) arsanilic acid is first diazotized and nitric acid then added to the solution; the mass is heated for some time or allowed to stand for several weeks; the product separates out as a crystalline mass.  Examples are also given of the purification of the product by first forming the sodium or potassium salt, followed if desired by conversion into the calcium salt, and then decomposing the salt to free the pure acid.  A purity test for the product using sodium hydrosulphite is described.

Abstract: 977, 662. Statistical apparatus. PHILIPS GLOEILAMPENFABRIEKEN N.V. May 10, 1963 [May 15, 1962], No. 18604/63. Heading G4M. A document which has information recorded on it in the form of legible characters also has a zone in which code bars corresponding to the characters are printed, the height of the zone being at least one quarter of the height of the document and overlying the area containing the legible characters by at least this minimum amount. The code bars which may be of conductive, special dielectric, magnetic or coloured ink are provided in zone 11, Fig. 2 Each document 7, Fig. 1 may be severed from a sheet, and consequently may have an irregular shape as shown by line 12 in Fig. 2. The chosen dimensions of the zone 11 and its overlap with the legible characters are such that the code bars are unlikely to be mutilated when the document is cut out from the sheet, and accurate alignment of the document edges is not essential for sensing the code bars. Each character is represented by five code bars 10, Fig. 4, the spacing between two bars in a group of five having one of two values. A start mark S and a finish mark F are provided at each end of zone 11, the marks S and F being symmetrical about their centres so that feeding of the document in the wrong direction may be detected. A further code bar zone bearing the same information may be printed on the other face of the document. The documents are fed between guides 31, 32, Fig. 5 on a conveyer belt under reading heads 33, 34 the spacing of which is such that the code zone of a correctly cut document 36 is sensed by both heads whereas the code bars of a badly cut document 39 are sensed by one of heads 33, 34 or by both heads in combination. The outputs of heads 33, 34.are fed to respective shift registers 37, 38, the outputs of which are combined. If the document has been fed in the wrong direction, registers 37, 38 may be read out in the reverse direction. A second pair of heads is provided for documents bearing a code zone on each face.

Title: Improvements in or relating to roller conveyors
IPC: B65G13/00
Filed: 1963-05-10
Abstract: 995,579. Roller conveyers. LONDON TRANSPORT BOARD, and F. J. S. FAULKNER. May 15, 1964 [May 10, 1963], No. 18626/63. Heading B8A. A driven roller assembly comprises a shaft 10 having mounted on it a sleeve 14 with an end flange 15. A pin 16 passing through the shaft projects into V-shaped slots 17 in the sleeve 14 which thus has limited movement on the shaft. A roller 18 is freely rotatable on the sleeve 14 and shaft. The inner surfaces of the flange 15 and of a disc 26 fixed on the shaft carry facings 28 of friction material. When the shaft is rotated, the pin 16 tends to ride up one limb of the slots 17, depending on the direction of rotation, thus tending to draw the flange 15 towards the disc 26 so that the roller is gripped between them and rotated with the shaft. If the roller is rotated by other means, e.g. by an article being pushed over it, there is insufficient torque on the sleeve 14 to move the latter axially into a tight gripping position, and the roller rotates substantially freely on the sleeve.

A single-ramp A/D conversion technique is employed whereby light is shone through a comparator solution to charge a first capacitor with the voltage generated at a first p.e. cell (not shown) and light is shone through the measurement solution to charge a second capacitor with the voltage derived at a second p.e. cell. The first capacitor is then discharged through a resistance and the time t taken for the two voltages to become equal is digitized by arranging that a gate 9 is held open for the time t to pass pulses from an oscillator 1 via divider 2 to a counter 4, decoder 5 and tube display 6. The measurement is first made with a standard solution with store 7 which controls the dividend at 2 being set at 1 and the results inserted into binary memory 7, and the measurement is then repeated with the measurement sample, this time the divisor of the divider 2 being equal to the value of the previous measurement. Hence the read-out at 6 at the second measurement is the ratio of the concentration of the two samples.
