IPC: G06F11/28
Filed: 1967-03-16
Abstract: 1,121,968. Halt instructions. BURROUGHS CORP. 16 March, 1967 [24 March, 1966], No. 12460/66. Heading G4H. A modified halt operation is provided particularly for use with multiprogrammed digital computers. As shown, a multiprogrammed digital computer comprises a core memory 10 for storing instructions and data relating to a master control programme and one or more object programmes. Instructions read from addresses generated by combining the contents of a programme instruction (" fetch ") counter 20 and a base address register 40 are passed through a memory register 14 to a command register 32 for decoding by a decoder 34. On detecting a halt instruction, a reference word is retrieved from an address in memory generated by combining the contents of a " breakpoint address " register 42 and the base address register 40, reference words being stored at the same address relative to the respective base address for all object programmes. Bits of this reference word, stored in register 14, are compared with bits of the instruction in command register 32 by a compare circuit 46. If inequality is detected, the computer merely steps on to the next instruction whereas if equality is detected, the contents of an " execute address " register 52 are transferred to memory address register 12 to retrieve from the part of the memory reserved for the master control programme a further reference word which is decoded in a decoder 58 to produce one of three output signals. A first of these signals (a " halt " signal) on line 60 switches off the source of clock pulses thereby stopping the computer. A second (" ignore ") signal on line 62 merely causes the computer to step on to the next instruction. The third ("interrupt") signal on line 64 causes a special interrupt word to be established in command register 32 by a generator 70 whereby a special interrupt procedure is initiated. A manual switch 66 is provided for restarting the computer after a halt.

IPC: C14C3/08
Filed: 1930-04-23
Abstract: Water-soluble nitrogenous products useful as tanning agents are obtained by condensing an aliphatic aldehyde with one or more polyhydric phenols, or a mixture thereof with a vegetable tanning material, and urea or a urea derivative at a temperature below 50 DEG C., preferably in the presence of a small quantity of acid condensing agent, the product then being heated if necessary to a temperature not exceeding 100 DEG  C.  The resulting products are assumed to have the formula R-O-A-NH-CO-NH2 where R is the radicle of the polyhydric phenol and A the alkyl radicle of the aldehyde employed.  The aliphatic aldehydes referred to are formaldehyde and acetaldehyde. The polyhydric phenols which may be employed are resorcinol, cresorcinol, phloroglucinol and pyrogallol or less advantageously catechol, quinol or hydroxyquinol.  Examples of urea derivatives are semicarbazide, carbazide, thio-urea, monomethyl urea and mono-ethyl urea.  The vegetable tanning agents which may be employed include quebracho extract, mangle bark extract, chestnutwood extract or the difficulty soluble phlobaphenes separated from quebracho extract. If products difficulty soluble in water are obtained by using more than half a molecular proportion of formaldehyde for each molecular proportion of polyhydric phenol, they can be rendered soluble by bringing their solutions to dryness in the presence of a small quantity of ammonia, caustic soda or like alkali.

Abstract: 683,312. Porcelain enamels. THORNTON, A. A. (Ferro Enamel Corporation). May 23, 1950, Neo. 12886150. Class 56. The colour effectiveness of different batches of commercially produced TiO 2  or the colour of different batches of porcelain enamel opacified by having smelted therein such different batches of TiO 2  are rendered uniform by determining the total amount of Ta, Cb, and W present as impurities in the TiO 2  and then adding to the TiO 2  at least one of the elements Ta, Cb, W so that the total percentage of all these elements in each of the TiO 2  batches is from about 0.1 per cent to about 0.2 per cent, said percentage being substantially the same in each of the TiO 2  batches. Preferably the TiO 2  is substantially free of Cr. The percentages of Ta &c. are determined by spectographic quantitative analysis, and it is found that 0.2 per cent of Ta, &c., based on the total TiO 2  gives a desired bluish tinge, 0.1 per cent gives a neutral white, less than 0.1 per cent gives a creamy tinge, and above 0.2 per cent gives a bluish tinge which is too pronounced, but this latter amount may be used when the enamel composition has an unusually pronounced creamy tinge. The Ta, &c., may be added in any form which will be soluble, be retained in the glass, and will not add harmful ingredients such as Cr, and Fe. WO 3  is usually used. Alternatively the desired amounts of Ta, &c. may be arrived at by mixing different batches of TiO 2  containing different proportions of Ta, &c. The TiO 2  may be used as an opacifier as a mill addition or preferably as a smelter addition, e.g., as 5-20 per cent of the raw mix. The raw mix may be formed from the following ingredients in the given weight percentage ranges, Dehydrated Borax 5-25, Feldspar 5-15, Soda Ash 0-10, Potash Nitrate 0-10, Zinc Oxide 0-5, Mono Ammonium Phosphate 0-25, Sodium Silica Fluoride 0-10, Titanium Oxide 5-20, Silica 0-40, Talc 0-5, Sodium Nitrate 0-15, Potassium Silica Fluoride 0-15, Cryolite 0-10. A given example gives a frit composed as follows, Na 2 O 8.38, Al 2 O 3  1.62, SiO 2  45.80, B 2 O 3  11.65, K 2 O 5.10, Zno 2.00, F 3.06, TiO 2  18.00. This enamel is smelted at 2250 degrees F and the frit produced therefrom milled as follows, 100 lbs. Frit, 5 lbs. Enamellers clay, 1 lb. TiO 2  (commercial ceramic grade), 8 ozs. Potash Carbonate, 36 lbs. water. The resultant may be applied as a single coat, as a plurality of coats, or as a finishing coat over other white enamels. The Ta, Cb, and W appear to affect the crystal growth of the TiO 2  to give the required result, and may influence the oxidation of the TiO 2  to one of its blue oxides.
