Patent GB-1130011-A (GB)
Title: Improvements in or relating to decade counter circuits
Inventor: COCKSEDGE KENNETH WILLIAM
IPC: H03K23/00
Filed: 1965-02-05
Abstract: 1,130,011. Electronic counters. BELL PUNCH CO. Ltd. 3 Feb., 1966 [5 Feb., 1965], No. 5069/65. Heading G4A. When terminal 2 is marked a gate opens to pass input pulses from 1 to a first bi-stable pair 11. When the pair restores at the second pulse it pulses a switch gate comprising rectifier 14 and capacitor 17. As transistor 18 is normally conducting this first carry pulse reverses bi-stable pair 19 which then biases switch gate rectifier 14 so that subsequent carry pulses pass to bistable pair 16 which controls further bi-stable pair 20 in normal cascade manner. Pairs 11, 16, 20, 19 are thus weighted 1, 2, 4, 2 and when the tenth pulse restores all the pairs a decade carry pulse appears at 24. The transistors of the counting circuit are connected in known manner to an indicating tube 28. The counting circuit may be zeroized by earth on lead 27 or may be set to a predetermined number in known manner. The decade carry pulse may cut off potential from terminal 2 to stop counting.

Abstract: 1426857 Paint stripping composition KOLENE CORP 4 Feb 1974 05069/74 Heading C5D A composition for stripping paints from surfaces comprises (A) one or more alkali metal hydroxides, or a mixture of one or more metal hydroxides and one or more alkali metal carbonates, the carbonates not exceeding 20% by wt. of the total composition; (B) an alkali metal nitrate; (C) a catalyst consisting of an alkali metal permanganate, MnO 2  or Cr 2 O 3 ; (D) up to 15% by wt. of an alkali metal chloride ; the ratio of (A) to (B) being between 4 to 1 and 1 to 1. (A) may be a mixture of sodium hydroxide and potassium hydroxide, wherein the KOH does not exceed 20% by wt. of the total composition and does not exceed the amount of NaOH. A preferred composition contains 20% NaOH, 19% KOH, 37% NaNO 3 , 10% NaCl, 1% MnO 2  and 13% Na 2 CO 3 . Paint is stripped from surfaces by contacting the surfaces with a fused bath of the above stripper composition at a temperature of 800‹ to 900‹ F. The operation is rendered automatic by periodically lowering the temperature to 700‹ F. in order to precipitate Na 2 CO 3 , which carries down with it, particles of inorganic pigment, originally present in the paint. The operation is maintained by passing air or oxygen through the bath to reconvert nitrite to nitrate and by topping up to maintain the concentration of alkali metal hydroxide in the molten composition. Specification 464,982 is referred to.

Title: Improvements in the production of cellulose esters
IPC: C08B3/08
Filed: 1946-02-19
Abstract: A cellulose ester of an organic acid containing at least three carbon atoms is obtained by submitting cellulose to the action of the anhydride of the organic acid in presence of the organic acid itself and an esterification catalyst, incorporating a further quantity of the organic acid with the esterification mixture when esterification is nearly complete, allowing reaction to continue at least until the esterification mixture is substantially clear, and then precipitating the cellulose ester.  The cellulose ester is precipitated in a fibrous open condition which facilitates the purification treatment. The organic acid may be propionic, butyric, or other aliphatic carboxylic acid, and the catalyst may be sulphuric acid.  When the mixture has become clear, the dissolved cellulose ester may be submitted to a ripening treatment at elevated temperature.  In the production of cellulose propionate, the esterifying medium may comprise 3-6 parts by weight, on the cellulose, of propionic anhydride, 0.2 to 1.0 parts by weight of propionic acid, and 0.01-0.09 parts of sulphuric acid.  The cellulose may be pre-treated with a mixture of propionic acid, formic acid and sulphuric acid. The entire amount of propionic acid present during esterification is preferably added to the cellulose during the pre-treatment.  Prior to charging the pre-treated cellulose into the esterification vessel, the mixture of anhydride, sulphuric acid, and propionic acid, if a further quantity of this is needed, is preferably cooled to -12 DEG to +5 DEG  C.  The temperature is permitted to rise during the esterification to a maximum of 20-38 DEG  C.  When the ester contains from 2.75 to 2.95 propionyl groups, the further addition of propionic acid is made, preferably in an amount of 1-5 times the weight of the cellulose.  Esterification is allowed to continue for 1-4 hours or until the mixture is clear and free of fibres. Water is then added to destroy any excess of anhydride and to allow ripening to proceed. The sulphuric acid may then be neutralized by adding magnesium carbonate.  The cellulose propionate is precipitated by the addition of water.  The cellulosic material may be cotton, cotton linters, wood pulp, regenerated cellulose, grasses, straws, hulls or bagasse.

Filed: 1937-02-25
Abstract: 484,245. Baling - presses. LINDEMANN, W. Feb. 25, 1937, No. 5717. [Class 94 (i)] Baling-presses are arranged so that the preliminary compression takes place between pistons in a pressure box, after which the pistons are hydraulically or mechanically coupled together and move with the charge out of the pressure box and are then disconnected and effect the final compression. In the form shown, the press plate 2 is mounted on a piston 3 for action in the pressure box 1, and the counter-pressure plate 5 is mounted on a piston 6. When the preliminary compression has been effected, and the parts are in the position shown, the pressure of the medium opens a valve admitting pressure medium through a pipe 11 to cylinders 9, and simultaneously the cylinders 4, 7 are connected hydraulically through pipes 12, 13. The pistons 8 then raise the pistons 3, 6, carrying the charge between them, out of the box, the pressure medium in the cylinder 7 escaping through pipes 12, 13 to the cylinder 4, so that the thickness of the bale remains unaltered. When the counter-pressure plate 5 has reached a predetermined position, it operates a control valve to admit fresh medium to the cylinder 4 and the final compression thus takes place outside the pressure box. In a modified form, the pistons are mechanically coupled by clamping members after the preliminary compression has taken place.
