The clay forms a false body composition capable of suspending scouring abrasives. The compositions are physically and chemically stable and are capable of remaining in contact with surfaces for a long period of time. The buffering agent may be a mixture of tetrapotassium pyrophosphate and trisodium phosphate in a weight ratio of about 2 : 1 and a mixture of anhydrous sodium carbonate and sodium acetasilicate in a weight ratio of about 3 :1.

Title: Minimum pulse width limiter
IPC: H03K5/04
Filed: 1966-07-07
Abstract: 1,087,749. Transistor pulse circuits; facsimile transmission. XEROX CORPORATION. July 7, 1966 [July 8, 1965], No. 30477/66. Headings H3T and H4F. A complementary transistor circuit ensures that a two-level signal subsists at each level for at least a given minimum period, for example, to ensure that short duration facsimile signals are not too short for the transmission system to handle. The circuit shown comprises an input transistor 101 which forms with a PNP transistor 103 a monostable multivibrator for negative-going signals and with an NPN transistor 104 a monostable multivibrator for zero level signals. Thus, for example, when a zero level signal cuts off transistor 101, transistor 104 is cut off for a period determined by coupling capacitor 31 and variable resistor 42. The output of this transistor is fed back to a diode gate 21, 22 to prevent transistor 101 being switched off during this period. If the signal still remains zero, the transistor will remain cut off until the signal terminates. The other flip-flop acts similarly for negative-going signals. Accordingly, an output taken from transistor 101 through inverter transistor 105 follows the input signal but extends short duration signals to a minimum width.

Abstract: 945,103. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. July 18, 1962 [Aug. 24, 1961], No. 30484/61. Heading H4K. A call-detecting device which is not liable to damage from high voltage surges on the line comprises a saturable core transformer T2 having balanced windings WA, WB in the line and a sensing winding WC in series with a high-frequency generator G which supplies voltage by way of a Zener diode Z 1 to the base of a transistor TX1, the latter being normally conducting. When the line is looped, the D.C. flow drives the transformer core towards saturation and reduces the inductance of winding WC so that the control voltage falls below the breakdown voltage of Z 1 and the transistor ceases to conduct. The additional saturable core transformer T3 is a load for T2 and prevents it from saturating when the loop is first opened during dialling. The transformer T1 serves for the supply of supervisory tones.

In one method of manufacturing such pads a non- woven layer 13 of polyester, nylon, acrylic, modified acrylic, polyolefin or polyacetal fibres is fed on to a polyurethane, cellulose or natural latex foam layer 11, and the juxtaposed layers 11, 13 passed under a reciprocating punch 17 comprising barbed needles 18 which pass fibres from the layer 13 completely through the layer 11 to emerge at the lower surface thereof as looped and unlooped ends. The fibrous layer 13 is then sprayed by a nozzle 24 with a mixture of polyvinyl chloride, carboxylated acrylonitrile-butadiene copolymer, and melamine-formaldehyde resin, and by a nozzle 26 with a mixture of melamineformaldehyde resin, bentonite, and abrasive materials, viz. silica sand and silicon carbide. The layers are then passed through a curing oven 27 and the foam layer 11 subsequently sprayed by a nozzle 31 with a styrene-butadiene copolymer, or other elastomeric binder, e.g. natural rubber, polyisoprene, or butadiene acrylonitrile copolymer. Finally the coating 33 on the layer 11 is cured in an oven 32, and the product cut to form pads. The abrasive-coated side of the pad is suitable for cleaning hard surfaced pots and pans, whilst for cleaning such articles when coated with polytetrafluoroethylene the coated surface of the foam layer 11 is used. In a modified pad a layer of coarsely woven serim material is interposed between the layers 11, 13.

[Also in Group XII] Oxygen is blown on to the surface of steel in an open hearth furnace through a water cooled pipe which is controllably lowered through a hole in the furnace roof. As shown, a pipe 1, comprising an internal pipe 7 conveying oxygen from a supply thereof and two concentric annular spaces through which a coolant, e.g. water, flows, is supported in guides 18 and lowered by a rope 2 and winch 5 through a hole 26 in the furnace roof 25.

Patent GB-376604-A (GB)
Title: Process of producing disinfectants and dentifrices
IPC: A61Q11/00
Filed: 1931-11-07
Abstract: A disinfectant or dentifrice comprises a soluble sulphocyanide treated with a protecting substance for nullifying its hygroscopic properties, and a solid water soluble acid substance such as an acid or acid salt.  The added protective substance should be such as will not impair substantially the solubility of the sulphocyanide.  It may also be added to the acid component before admixture with the sulphocyanide.  Suitable protective substances are tragacanth, gelatine, albumin, dextrin, saponin, and the like, to which a suitable hardening agent may sometimes be added, e.g. formaldehyde, tannic acid.  Gypsum is also suitable as a protective agent. Alkaline substances may also be added, e.g. borax, carbonates or bicarbonates and these are rendered sufficiently difficultly soluble by a coating substance such as resin to enable the sulphocyanic acid to become effective before recombination with the alkaline substance. Suitable acid substances for effecting the decomposition of the sulphocyanide are tartaric, citric, boric acids and potassium bisulphate.  The components may be separately granulated with the protective agents and then mixed.  Carbonates are effective additions to dentifrices and powders for mouth washes &c. and may be mixed with the sulphocyanide and a protective agent before admixture with the acid, which in this case will be in quantity sufficient to react with both the other components.  The mixtures may have a polishing agent added to produce a dentifrice.  They may be formed into tablets &c. or converted into a paste by admixture with a liquid in which the substances are insoluble.  According to an example a mixture of calcium sulphocyanide, saponin, and saccharine is dissolved in water and the solution stirred with sufficient gypsum to produce a slightly moist mass which is dried at 70-80 DEG  C. Tartaric acid is mixed with tragacanth and a small quantity of alcohol stirred into the mixture, the mass being then dried.  The two components are then intimately mixed.

Title: Manufacture of barium titanyl oxalate and of barium titanate therefrom
IPC: C01G23/00
Filed: 1955-11-01
Abstract: Barium titanyl oxalate is prepared by calcining at a temperature of at least 1035 DEG  C. a mixture of titanium dioxide and barium oxide or a compound yielding barium oxide at the temperature employed, extracting the product of the calcination with excess of aqueous hydrochloric acid, removing insoluble impurities from the extract, precipitating barium titanyl oxalate from the resulting acidic solution with oxalic acid and washing the precipitate with water. The product on calcination yields barium meta-titanate (see Group III).  Rutile and barium oxide, hydroxide or carbonate may be used as starting materials.  In examples, finely divided TiO2 and BaCO3 in a weight ratio of 2 : 5 are fed through a rotary kiln the temperature of which ranges from 480 DEG  C. at the inlet to about 1150 DEG  C. at the outlet and after a residence time of 6 hours, the product is heated in concentrated HCl, the resulting mixture is diluted with water and filtered; the solution, said to be of barium and titanium chlorides, is then mixed with a warm aqueous solution of oxalic acid and the slurry of barium titanyl oxalate so formed is filtered and the oxalate is washed with water until free of chlorides and then dried.ALSO:Barium meta-titanate is prepared by calcining at a temperature of at least 1035 DEG  C. a mixture of TiO2 and barium oxide or a barium compound, e.g. the hydroxide or carbonate, which yields the oxide at the temperature employed, extracting the product of the calcination with an excess of aqueous hydrochloric acid, removing insoluble impurities from the extract, precipitating barium titanyl oxalate from the resulting acidic solution, said to contain barium and titanium chlorides, by means of oxalic acid, washing the precipitate with water and then calcining it at a temperature of at least about 700 DEG  C. to obtain barium meta-titanate.
