Title: Washing agents and washing aids having a bleaching action
IPC: C11D3/395
Filed: 1966-03-25
Abstract: A washing agent having a bleaching action contains an active-chlorine containing compound capable of releasing chlorine in cold water, and an enveloped percompound, the envelope of which comprises a water-insoluble fatty acid or hydroxy-fatty acid ester of glycerine, the acid radicals having 8-26 C atoms, and which releases the enclosed percompounds on heating in aqueous phase in the range 40-70 DEG  C. In the case of di- or tri-glycerides there may be present, per molecule, in addition to the 8-26 C acid radicals, 2-7 C acid radicals of the same type, bound by ester linkages.  The envelope may also comprise at least 50% of a mixed glyceride containing at least one of the aforesaid 8-26 C acid radicals per molecule, and at least 0.25 radicals per mode of 1-10 C di- or polycarboxylic acids, bound by ester linkages, the aforesaid 2-7 C acid radicals optionally being present to a maximum extent of 1 radical per mole.  Specified active-chlorine compounds are hypochlorites, adducts thereof with phosphates, and organic N-chloro compounds, of which many are named. Specified percompounds are perborates and perhydrates of, e.g. pyro- and tripolyphosphates.  There may also be present cationic, nonionic and anionic surfactants, of which many are named, alkaline or neutral salts, complex-formers, soil carriers and foam controllers.  Suitably the ratio of percompound to active-chlorine compound is 2/3 -5 : 1 on a basis of amount of percompound theoretically needed to destroy the active chlorine present.

Title: Improvements in or relating to image intensifiers
Inventor: SCHAGEN PETER
IPC: C03B37/15
Filed: 1963-04-03
Abstract: In manufacture of a channel intensifier device having input and output electrode layers on its major faces, and elongated resistive and secondary-emissive channels extending therebetween, a number of tubes are essembled into a bundle and sealed together, whilst being forced to merge together to the extent of filling the interstices therebetween, to form a rigid channelled block.  The intersifier device may be used in light or X-ray image intensifier of the kind described in Specifications 1,064,073 and 1,064,074. The tubes may be lengths of hollow drawn glass tubing or may have metal cores which are removed after formation of the block.  In the latter case, the tubes may be obtained by drawing glass tubing over a metal wire, by drawing glass tubing which already contains a metal core, or by pulling a preformed wire through a bath of molten tube material. The tubes so formed, with or without cores, may be assembled into bundles by winding single or multiple drawn tubing into a hank and cutting the hank into lengths.  The bundles may be packed into tubular glass formers which are heated to softening point and evacuated to seal the tubes together under pressure, hollow tubes being air-filled to prevent collapse. Alternatively the bundles may be packed in carbon jigs, so that upon heating the tubes expand more than the carbon and are thus compressed together.  The tubes may be coated with a low-melting point glaze to enable sealing to be effected at a lower temperature. After sealing, the bundles may be sliced to form the final matrix or may be drawn down to form multiple fibres which are assembled together to form the final matrix.  In the latter case, the multiple fibres should be of regular cross-section, e.g. square, triangular, diamond or hexagonal, to permit close packing in the final bundle.  The metal core material, if used, may be In, Pb, Sn, Zn, Al, Cu, W or Au and may be melted out or removed by chemical etching.  The tubes may be of lime soda or borosilicate glass, and may have slightly conductive layers on their inner surfaces, or may have a bulk resistivity of 109-1011 ohms/cm. Specific dimensions are given.

IPC: C22B19/02
Abstract: 134,825. Electrolytic Zinc Co. of Australasia Proprietary. Nov. 7, 1918, [Convention date]. Sulphatizing.-In the roasting of zinc sulphide ores, concentrates, tailings, &c., particularly zinc blende, preparatory to leaching for the formation of sulphate solutions such as in the manufacture of lithopone, the ore is roasted in two stages, the first at a relatively high temperature for the reduction of the sulphide contents, and the second at a lower temperature under such conditions as to form a maximum amount of sulphates. In the first stage, the sulphide sulphur contents are reduced to about 6-10 per cent, the second stage being carried out under control of temperature and air supply, with or without the addition of unroasted or sulphatized material. In a modified method, the first roast may be a dead roast, unroasted ore or other sulphide material being thereafter added to bring the sulphide sulphur contents to about 6-10 per cent, or preferably in successive additions to bring the sulphide sulphur contents to about 2 per cent at each addition, and the sulphatizing roast being then proceeded with. A catalyst such as ferric oxide may be present in the ore or may be added.

Filed: 1924-06-04
Abstract: 223,533. Soc. Anon. AciÚries RÚunies de Burbach-Eich-Dude-Lange. Oct. 16,1923, [Convention date]. Casting-appatatus ; casting slag. - The heat from continuously cast slag &c. is extracted in an enclosed space by air or other cooling fluid, which is then passed through steam generators, or furnaces &c. in order that the extracted heat may be utilized. Molten slag is supplied ta rolls b, Fig. 1, that pick up a film or band and pass it over perforated and stepped cooling surfaces d, on which it may be broken up by tilt hammers g, the pieces falling into hoppers h with closing cones k and discharge doors l. Air is drawn from the steam generator by a pipe o and a blower p delivers part of the air under pressure to outlets t under the cooling surfaces d. A second blower s delivers the remainder of the air at a higher pressure to the hoppers h. All the air eventually passes in a heated condition at n to the steam generator, superheater, and feedwater heater m. The tilt hammers may be replaced by crushing rolls or the strips may be delivered unbroken for use as slates, flagstones, &c. Air heated as above may be passed direct into a metallurgical furnace, the circuit for the air in this case not being a closed one. The apparatus may be employed in connection with the liquid slag type of gas generators, permitting the use of fuels rich in ash. The Specification as open to inspection under Sect. 91 (3) (a) describes several forms of casting-apparatus. In one form slag &c. is fed by a trough a, Fig. 1, and passes under a partition f to a cylinder b which delivers by a hopper c to a cooling-incline d. The cylinder may be arranged to form a part of the containing surface of the trough and may be roughened or grooved to form bands of particular shapes. The material may leave between a pair of rolls b, b', Fig. 6 (Cancelled), and may be finished by a further pass if desired without reheating. Whein a continuous mill is employed cooling jets of air may impinge on the material between the passes. A pair of rolls b, Fig. 9 (Cancelled), may form the bottom of the trough, two bands being formed simultaneously, the rolls b<1> being optional. The rolls b may be inclined, surplus material being delivered at the lower end to a similar pair of rolls b<11>, Fig. 11 (Cancelled). Further roll pairs may be employed. This subject-matter does not appear in the Specification as accepted.

Filed: 1969-03-18
Abstract: 1,204,107. Selective signalling. INTERNATIONAL BUSINESS MACHINES CORP. 18 March, 1969 [11 April, 1968], No. 14010/69. Heading G4H. [Also in Division G1] The position of a probe 12, Fig. 3, manually movable in two dimensions X, Y, is detected by capacitively picking-up for each dimension, a saw-tooth modulated signal, e.g. Fig. 5A, in which the time, within the modulation cycle, at which the modulation passes through zero represents the probe position. This time can be either digitized or converted to a corresponding voltage amplitude. The probe 12 is arranged above two sets of conductors 10, each set being joined to different tapping points on two resistors X 1 X 2 , Y 1 Y 2 . The ends of each resistor are energized simultaneously by signals, Fig. 5B and 5C. These result in a null point being swept across each resistor, and thus the time, within a modulation cycle, at which the null reaches the probe represents the probe position. In the preferred embodiment the X and Y co-ordinates are measured separately. The required signals are generated by modulators 44, 46 under the control of a counter 34. The probe output is amplified 20 and demodulated 22, and a circuit 24 is arranged to produce a pulse which is positive at the beginning of a modulation cycle and which remains positive until the null point occurs. Thus, the duration of this pulse represents the co-ordinate being measured and after passing through an X-gate 26 or a Y-gate 30 it can either be integrated to give an analogue output, or its trailing edge can gate the contents of the counter into an appropriate register to provide a digital output.
