Title: Improvements in or relating to control mechanism for calculating machines
IPC: G06K13/26
Filed: 1960-08-04
Abstract: 917,032. Calculating machines. BURROUGHS CORPORATION. Aug. 4, 1960 [Aug. 5, 1959], No. 32052/61. Divided out of 917,031. Drawings to Specification. Class 106 (1). Control mechanism for a calculating machine comprises a sensing element movable between unoperated and operated positions, but capable of being retained in its unoperated position by the depression of one of a number of operation control keys, and a power-operated mechanism, which moves a control element from a first to a second position when the sensing element is retained in its unoperated position. In the machine disclosed, which is fully described in Specification 917,031, several sensing elements are each controlled by selected ones of a group of control keys and the control elements associated with the sensing elements respectively effect appropriate controls in the machine. Further sensing elements controlled by the amount keys are associated with control elements which prevent the completion of machine cycles initiated by Total, Sub-total and No-sale keys if any amount key is depressed. The sensing elements are in the form of slides with sensing projections. The latter may be readily adjustable lugs or the slides may be formed with a full complement of projections which may readily be removed in the positions where they are not required. The control mechanism is thus easily modified and each control element for performing a particular machine function may readily be actuated under the control of any chosen control keys. U.S.A. Specification 1,853,050 also is referred to.

Patent GB-428792-A (GB)
Title: Improvements in or relating to the manufacture of alcohols and ethers
IPC: C07C29/06
Filed: 1933-11-20
Abstract: In the hydrolysis of acid olefine absorption liquors for the production of alcohols and ethers, the acid liquor and water are fed to a tower column or the like substantially above the lower end which is indirectly heated, vapours of the product being withdrawn at the top and regenerated acid at the bottom.  Direct or live steam heating must not be employed.  A dephlegmator may be arranged at the top of the tower, and may return 80 per cent of the product as condensate; the tower may contain plates or filling bodies such as Raschig rings or pumice.  The initial liquor may be obtained by absorbing propylene in 85--90 per cent sulphuric acid, and may be diluted with from half to an equal weight of water. The regenerated acid may be used for the absorption of the same or higher olefines and, if desired, may be used in three or more steps each requiring acid of lower concentration than the last. Absorption products in which other acids such as phosphoric or a sulphonic acid such as benzene sulphonic acid have been used may be treated.  In examples: (1) propylene is absorbed in 90 per cent sulphuric acid and the liquor, diluted so as to contain 5 molecules of water to one of isopropyl sulphuric acid, the mixture being fed into the top of a copper column packed with pumice and provided with a dephlegmator, the base of the column being heated to 130 DEG  C.; (2) ethylene is absorbed in 80 per cent sulphuric acid, an equal weight of water is added, and the mixture is fed into the middle of the column, the base being heated to 125 DEG C. In both cases the alcohol is withdrawn as vapour at the top, and acid at the bottom.

Abstract: 1,111,252. Cold separation of gas mixtures. LINDE A.G. 19 July, 1966 [20 July, 1965], No. 32290/66. Heading F4P. In a gas mixture, e.g. air, separation process wherein water vapour and carbon dioxide are condensed from feed air in interchangeable paths C or D, Fig. 1, of a plate-type head exchanger 3, and is subsequently re-vaporized by passage therethrough of a cold separated component, e.g. crude oxygen leaving a column 6 through a line 20 and wherein cold is produced by alternately compressing and expanding at 15, 13 a circulating gas, e.g. nitrogen, which traverses non-switchable paths A, B of exchanger 3, the flow paths A, B, C, D of the latter are arranged in the repeated grouping A-n(D-C)-A where n is a whole number and path B is located between adjacent pairs of groups. Fig. 4 shows the arrangement when n is unity. In operation product liquid nitrogen is withdrawn from column 6 through a line 7, crude scavenging oxygen gas is withdrawn from a condenser 16 through a line 20 and pure circulating nitrogen gas is withdrawn from the head of column 6 through a line 8 and added to the nitrogen leaving expander 13 in equal quantity to a portion of compressed nitrogen leaving the cold end of flow path A and which by-passes expander 13 and is liquefied in an exchanger 10 before being expanded at a throttle 12 into column 6. In a modification for production of liquid oxygen, air is used as the circulating refrigerant gas and that portion of compressed air which by-passes the expander (60), Fig. 2 (not shown), is passed through a liquefier (45) and added to the feed air as it enters the column (39), and an equal quantity of cold feed air is added to the expanded circulating air through a line (41).

Title: Improvements in or relating to a method of forming foamed plastic products
Inventor: KINGSLEY HARRY
IPC: B05D7/02
Filed: 1961-03-22
Abstract: A method of forming sheeting of foamed plastics material comprises applying to at least one surface of a preformed foamed plastics sheet a paste or plastisol of a thermoplastic synthetic resin material, applying heat to the paste or plastisol-coated material so as to avoid thermodecomposition of the foamed plastics material and to set or gel the thermoplastic layer and thereby cause it to adhere as a coating skin or sheet to the surface of the preformed foamed plastics sheet.  The foamed plastics sheet may be supported on a resilient surface and may be held under suitable tensioning and straightening devices during the application thereto of a layer of the paste or plastisol by means of doctor blade, spreading or lick coating.  The coated sheet may be passed through a heating chamber where the heat is applied from above to the skin or coating of thermoplastic material.  After heating the coated foamed plastics sheeting a water cooled roller may be applied under pressure to the skin or coating. The roller may be embossed or otherwise patterned so as to effect the formation of a permanent decorative effect on the coating skin or sheet.  The foamed plastics sheet may be of polyurethane or a polyvinyl compound.  The coating may be of polyvinyl compound e.g. polyvinyl chloride, polyvinyl acetal.
Patent GB-410816-A (GB)
Title: Improvements in or relating to the manufacture of hydration products of olefines
IPC: C07C29/06
Filed: 1932-11-18
Abstract: The alcohols or ethers produced by hydrolysis of the products obtained by absorption of olefines in strong acids such as sulphuric or phosphoric acid, are separated by adding an organic liquid acting to extract the alcohol or ether or to entrain the alcohol or ether and if desired the water in a distillation process.  Suitable liquids are benzene, decahydronaphthalene, tetrachlorethane, chlorbenzene, and petroleum fractions of boiling-point between 80 and 150 DEG  C. When the added liquid is to be used as a solvent, chlorbenzene, hydrogenated naphthalenes, or tetrachlorethane are suitable in the case of ethyl alcohol, while for entraining ethyl alcohol, benzene, trichlorethylene n-hexane, cyclohexane, and chloroform are suitable, while diethyl ether may be entrained by n-pentane.  When an entraining agent is employed, it may be brought into contact with the alcoholic liquor in liquid or vapour form, and the solvent layer of the distillate may be returned to the distillation apparatus.  A salt such as ammonium sulphate may be added to the alcoholic liquor before extraction of the alcohol.  In examples (1) the product of the absorption of ethylene in sulphuric acid is diluted with ammonium sulphate solution and extracted with chlorbenzene in two stages; (2) the hydrolysis product of the absorption of isobutylene in sulphuric acid is extracted with benzene in three stages; an aqueous solution of the alcohol may be obtained by treating the extract with water; (3) the hydrolyzed product of the absorption of propylene in sulphuric acid is distilled with n-hexane; (4) the hydrolyzed product of the absorption of ethylene in sulphuric acid is distilled with cyclohexane or benzene; (5) the same hydrolysis product is passed down a column, the top of which is maintained at 70 DEG  C. and n-hexane vapour is passed up the column.  Specification 389,134 is referred to.

Title: Solid state television cameras
IPC: H04N9/07
Filed: 1975-08-05
Abstract: 1511526 Television SONY CORP 5 Aug 1975 [22 Aug 1974] 32669/75 Heading H4F A colour television camera includes a solid state CCD image sensor (described with reference to Fig. 1 (not shown)) comprising an array of photosensitive elements 1 1-1 , 1 2-1 , ... etc., Fig. 5, which is marked by a reticulate filter 16. Cyan Cy, red R, blue B, and yellow Ye, windows recurrently arranged as in Fig. 5 constitute filter 16 there being provided one window, in front of each element, which is centrally offset by a distance # 1  to # 4 , #H being the row alignment pitch of the elements. Lines 4a, 4b represent consecutively scanned lines of elements. The video signal produced by the sensor is in the form of averaged pulses, Fig. 5D, obtained sequentially from each of the elements 1 1-1 , ..., row by row. These are gated to form a second signal, Figs. 5B and 5C, corresponding respectively to odd and even scan lines, made up of shorter duration pulses which coincide temporally with the spatial location of the window in front of the respective element. These spatial window locations and consequently the temporal signal gating, are selected to provide a desired colour phasal relationship (described with reference to Figs. 2 to 4 (not shown)) which avoids sampling errors due to overlapping D.C. and side band components. The frequency spectra and phasal relationship given by the employed spacing (i.e. # 1  = # 4  = 0À115 #H, # 2  = # 3  = 0À25 ##H) for odd (m) and even (m+1) rows are shown in Fig. 6A and 6B. These signals are combined between lines employing a 1 line delay, and filtered to produce SDC Fig. 6C. The chrominance signal SMO(E), Fig. 6D, containing some high frequency D.C. components SDH which do not cause intolerable disturbance, is demodulated and matrixed with the D.C. component suitably delayed to produce standard NTSC output. If the band of the D.C. component S DC  is 3À5 MHz and the sensor sampling frequency is 9 MHz the spectra of Fig. 7A is obtained the carrier being 4À5 MHz. Filter 16 may comprise other colour windows it being requisite to have on one set of alternate lines a primary colour window in alternation along each line with its complementary colour window, and on the other set of alternate lines a different primary colour window in alternation along each line with its complementary colour window, whereby the two complementary colours will have in common the third primary colour (e.g. odd lines: green, magenta, g...; even lines: blue, yellow, b...: or odd lines: red, cyan, r...; even lines: green, magenta, g).
