Title: Improvements in and relating to the depositing of protective coatings or films on metal surfaces
IPC: C23C22/23
Filed: 1946-11-09
Abstract: A composition which in aqueous solution will deposit an amorphous metal-phosphate coating on metals-particularly iron, steel, zinc, copper, silver, magnesium and their alloys-comprises essentially (a) at least one water-soluble salt of a coating metal selected from Ca, Zn, Co, Mg, Cd, Fe, Al, Ba, Sr, Mn, Cr, Ni; (b) a molecularly dehydrated alkali-metal or ammonium phosphate glass; (c) a material which functions in the solution as an oxidizing agent, e.g. a nitrate, nitrite, sulphite, permanganate, chromate, dichromate, perborate, ferricyanide, hypochlorite, together with if necessary a pH adjusting material to ensure a pH value of the solution between 3 and 8; the proportions of the components (a) and (b) being such that when the composition is dissolved in water the ratio of (b) to the metal ion of (a) is from 0.05 : 1 to 12 : 1, whilst the amount of (c) is such as to give a concentration of at least 10 p.p.m.  In a modification, the component (a) comprises salts of both Ca and Al, and the components (and pH adjusting material if used) are chosen to give a pH between 2 and 8.  Preferably the phosphate glass has a molecular ratio of alkali metal oxide (M2O) to P2O5 of from 0.4 : 1 to 1.7 : 1, and typical compositions are by weight, 49.2 per cent sodium metaphosphate glass, 34.7 per cent of 78 per cent calcium chloride, 6.6 per cent sodium nitrate, 9.5 per cent acid sodium sulphate; 54.62 per cent sodium metaphosphate glass, 38.6 per cent of 78 per cent calcium chloride, 0.7 per cent sodium bichromate, 6.1 per cent acid sodium sulphate, the M2O : P2O5 ratio in the phosphate glass of these examples being 1.1 : 1.  The compositions are dissolved in water sufficient to ensure the presence in solution of 100-10,000 p.p.m. of the metal coating ion of component (a), and at least 200 p.p.m. of the phosphate glass (b)-their sum being from 300 to 50,000 p.p.m. and the ratio of phosphate glass to metal coating ion being preferably between 2 : 1 and 12 : 1. The solution is applied by dipping, spraying, rolling, &c. and preferably at temperatures between 15 DEG C. and 50 DEG C., and the examples given show the use of solutions containing 1.4-2.5 per cent by weight of the composition.  The composition ratio of the components (a) and (b) is said to remain constant down to a depletion of 35 per cent of the original value of the solution; and the solution may be restored to its original effectiveness by the addition of more of the composition.  The phosphating treatment may be succeeded by a rinse with an adjusted solution of chromic acid or a salt thereof, the solution having a concentration of CrO3 between 0.05 and 0.5 per cent and pH bewteen 3.9 and 5.5.  The coating of the process is said to form a good basis for a subsequent organic finish, e.g. of paint, varnish, lacquer or of enamel, and the use of a Ni salt in component (a) is said to be particularly effective when phosphating iron to which a subsequent vitreous enamel is to be applied.

Abstract: 944,413. Transistor amplifying circuits. HASLER A.G. Sept. 30, 1960 [Oct. 2, 1959], No. 33650/60. Heading H3T. In a transistor amplifying circuit of the kind having at least three stages, each including one transistor and in which the operating points of the first and second stage transistors are stabilized against variations in the transistor characteristics resulting from temperature variations or from exchange of one transistor for a similar transistor, the collector of the transistor of each stage, with the exception of the last but one and the final stage, is connected through a resistor to the emitter of the second following stage. As shown in Fig. 3 in a three-stage amplifier comprising transistors T 1 , T 2 , T 3  the collector current of the first transistor jC 1 , stabilized by feedback from transistor T 2  through resistors R 1 , R 2 , R 3 , flows through resistor R 4  connected between the emitter of transistor T 3  and a junction point between the collector of T 1  and the base of T 2 . Since the collector current jC 1  is stabilized and is substantially of the same value as the collector current JC 3  of transistor T 3  then the latter current is also stabilized. Further stability is obtained by the direct current feedback through resistor R 4 . In a further embodiment, Fig. 5 (not shown), the circuit is expanded to include five stages, in which the stabilized collector currents of the first and second stage transistors flow through the collector circuits of the third and fifth stage transistors and the fourth stage respectively.

Title: A new dielectric composition particularly suitable for use in sealing and/or insulating electrical conductors and devices embodying same
IPC: H01B3/46
Filed: 1945-12-12
Abstract: A composition for use as a dielectric material consists of an intimate admixture of a liquid organo-silicone and a minor proportion of an inorganic aerogel.  The aerogel may be of silica, aluminium oxide or iron oxide, or the fluffy ash obtained by burning the vapour of a volatile silicon compound, e.g. obtained by feeding silicon tetrachloride vapour into an oxygen-illuminating gas flame may be used.  The organo-silicone preferably has a viscosity greater than 500 Saybolt seconds at 100 DEG  F., and up to 10 per cent of aerogel may be employed.  The organo-silicone is obtained by hydrolysis and condensation of a mixture of average compositions R4-zSiXz where R is a lower alkyl radical, i.e. containing less than 6 carbon atoms, X is a halogen or alkoxy group and z is 1.5-2.25.  Hydrolysable p mono-alkyl and tri-alkyl silicon compounds may not constitute more than 25 per cent of the mixture.  The organo-silicone should have 1.75-4 atoms of C per atoms of Si.  The aerogel and polymer may be mixed on compounding rolls and may be heated at 250-350 DEG  F. to facilitate absorption of the polymer by the aerogel. Pigments, other colouring agents or a filler, such as mica, may be added to the composition.  The composition is particularly useful for use in connection with shielded sparking plugs when the high-tension cable is close to the grounded metal shield (see Group XXXVI).

Title: Electrolytic reduction of oxalic acid to glyxylic acid
IPC: C25B3/25
Filed: 1971-07-19
Abstract: 1411371 Electrolytically preparing glyoxylic acid and electrolytically removing oxalic acid therefrom NATIONAL RESEARCH DEVELOPMENT CORP 13 Oct 1972 [19 July 1971] 33849/71 Heading C7B [Also in Division C2] Glyoxylic acid is electrolytically prepared by cathodic reduction of oxalic acid at a solid cathode with a catholyte which is substantially free from supporting electrolyte, the process being such that over-reduction of the oxalic acid to glycollic acid is substantially avoided (e.g. by cooling the catholyte or cathode). Specified conditions are:- a catholyte comprising a saturated or supersaturated solution of oxalic acid in water or aqueous ethanol; an anolyte comprising an aqueous solution of H 2 SO 4 , HClO 4  or H 3 PO 4 ; the anolyte and catholyte separated by a permeable or semi-permeable membrane, e.g. a cation exchange membrane; a cathode of Pb, Cd, Tl or of various Hg amalgams; an anode of Pb, graphite, Pt, or platinized Ti; a temperature of not greater than 20 C (e.g. obtained by circulating water within the cathode); and a cathode potential not more negative than - 1.50v with reference to a saturated calomel electrode. When the process is stopped, any remaining oxalic acid can be removed from the resultant solution containing oxalic acid and glyoxylic acid by selective precipitation as the Ca salt or by anodic oxidation. For this removal of oxalic acid, specified conditions are:- a catholyte of H 2 SO 4 , HClO 4  or H 3 PO 4 ; a cathode of C, Cu, Pb, Monel (Trade Mark) metal, Ni or Pt; and an anode of graphite such as a fluidized bed or packed, e.g. bipolar, bed. The anodic oxidation converts the oxalic acid to CO 2  but the bipolar bed also converts a proportion of the oxalic acid to glyoxylic acid. In one alternative, the two stages for the production of pure glyoxylic acid are combined. A cell is used having a Pb cathode, a graphite anode, as catholyte an aqueous solution of oxalic acid, and as anolyte an aqueous solution of glyoxylic acid containing traces of oxalic acid which has been produced in the electro-reduction of oxalic acid. After operation, the anolyte is removed to be worked up for glyoxylic acid, the catholyte transferred to the anode compartment and the cathode compartment is charged with fresh oxalic acid solution.

Abstract: 519,510. Optical sound-reproducing apparatus; clocks. SOLBERG, T. A. Nov. 24, 1938, No. 34200. [Class 40 (ii)] [Also in Group XVIII] A time-controlled announcing system comprises two concentric cylinders separately rotated by gearing with a clock, one of the cylinders carrying a photographic or like announcement record and the other operating mechanism which reciprocates a photo-electric device for scanning the record in timed relationship with the clock, the scanner being adapted to operate sound-reproducing means. In the apparatus shown, an electric clock drives through gearing 3, 13 two cylinders 7, 14 the cylinder 7 being fixed on a spindle 4 and 14 being mounted, concentrically therewith, on bearings 15, 16. The cylinder 14 carries a photographic or like transparent sound record. Between the cylinders extends an arm of a U- shaped frame 9, which is guided on a rail 10 and which carries a photo-electric device for scanning the sound-record. The scanner comprises a lamp 11, an optical system 17, 18, and a photo-electric cell 19. In order to traverse the scanner longitudinally along the record, the inner end of the frame 9 carries a block 8 engaging in a groove 7a in the cylinder 7, Fig. 5, by which, as the cylinder rotates, the block, together with the frame carrying the scanning- device, is moved axially along the cylinders. Thus, the record track on the rapidly rotating cylinder 14 is scanned by the light passing through it from the lamp 11. The groove 7a is continuous, and changes the direction of its pitch at each end of the cylinder, so that the frame 9 is reciprocated. The photo-electric cell 19 is connected in the input of an amplifier which operates a loud-speaker, a suitable circuit being described and shown. Switching mechanism, operated by the clock, is provided to condition the amplifier for operation shortly before each time the passage of light through the sound-track is required to activate the photo-electric cell. For this purpose, a rotary contact arm driven by the clock bridges contacts in the circuit of the transformer which supplies current to the valves, before closing a circuit through the exciter lamp. In a modification, the contacts first closed by the clockdriven switch operate a low-voltage relay by which the transformer supplying the amplifier is energized. Instead of the optical system shown an elongated lamp with a movable shutter may be provided. The apparatus described may be used for announcing time, by speech or by chimes &c. for sounding an alarm, or for' making other announcements or signals, at predetermined times.

Abstract: 1,060,633. Semi-conductor devices. HITACHI Ltd. Aug. 30, 1963 [Aug. 31, 1962], No. 34383/63. Heading H1K. A method of selectively diffusing impurities into a semi-conductor body, comprises coating a surface of the body with a material containing both P and N type impurities, directing an electron beam at the coated surface so as to heat it to a first temperature at which one of the impurities preferentially diffuses into the surface and then altering the energy level of the beam so as to change the temperature at the surface whereby the other impurity preferentially diffuses in. A P type Si wafer (1-2 cm.) is coated with a solution of ethylene glycol monomethyl ether, metaboric acid and phosphorus pentoxide and a portion of the coated surface is then heated to 1000 C. for two hours by an electron beam whereby phosphorus diffuses into the surface to form a PN junction. The surface concentrations of phosphorus and boron at this time are 7 x 10<SP>19</SP> cm.<SP>-3</SP> and 3 x 10<SP>19</SP> cm.<SP>-3</SP> respectively. A part of the treated portion of the surface is then heated by the beam to 1200 C. for 25 mins. whereby boron diffuses into the surface to form a second PN junction, the surface concentration of boron then being 15 x 10<SP>19</SP> cm.-<SP>3</SP>. It is stated that the depth of the first junction is not substantially affected by the second heating process. The device is then washed in a solution of ethylene glycol monomethyl ether to remove the remaining surface impurities whereafter it is immersed in an HF acid bath to remove a vitreous layer formed on the portion subjected to the electron beam. Electrodes are then attached to complete the transistor.
