Patent GB-222423-A (GB)
Title: Improvements in the manufacture of adsorbent materials
IPC: B01J20/32
Filed: 1923-03-26
Abstract: Composite adsorbent precipitates suitable for the treatment of liquids such as sugar solutions and of gases are prepared by precipitating an alkaline earth salt and depositing upon it another alkaline earth salt, under such conditions as to produce precipitates having adsorbent properties, the precipitation being preferably effected above 80 DEG  C.  A precipitate of calcium carbonate may be prepared and a coating of dicalcium phosphate produced upon it by adding a small quantity of phosphoric acid. If the precipitate is to be dried, substances may be admixed with it to prevent the particles agglomerating.  Such substances may be tannin, starch, glue, or soda, or, when it is to be used for the treatment of sugar solutions, sugar may be used as the addition. A relatively expensive precipitate such as calcium phosphate, citrate, tartrate, oxalate or sulphite may be precipitated upon a relatively cheap precipitate such as calcium carbonate. Specifications 183,485 and 184,473, [both in Class 46, Filtering &c.], and 222,159 are referred to.

Title: Arrangement to decode digital signals and convert them into mechanical setting
IPC: G05D3/20
Filed: 1965-05-12
Abstract: 1,066,514. Electric selective signalling. INTERNATIONAL STANDARD ELECTRIC CORPORATION. May 12, 1965 [May 12, 1964], No. 20009/65. Heading G4H. In a feedback positioning system, parallel digital desired-position signals are converted into a phase-significant voltage by a logic network in dependence on signals from a binary counter which also produces a reference voltage having the same frequency as the phase-significant voltage, the reference voltage being used to generate a phase-significant actual-position voltage which is compared with the desiredposition voltage to obtain a correcting voltage, resetting signals for logic elements being derived from the reference voltage. In Fig. 1 (not shown), all the bits of the desired-position input, except the highest-order bit, go to respective AND gates the outputs of which are ORed and inverted to control two flip-flops, one of which provides a signal which is inverted or not depending on the highest order bit (to constitute the desired-position phase signal) and the other of which controls the AND gates. The AND gates are also controlled by respective stages of the (free-running) binary counter, and each AND gate (except the highest order) is also controlled by the inverted outputs of all higher order AND gates. Quadrature reference signals derived from counter stages feed the stators of a resolver, the rotor of which provides the phase-significant actualposition signal. Fig. 4 (not shown) shows a modification in which a coded disc produces the actual-position signals which are converted to a phase-significant voltage in the same way as the digital desired-position signals, the same counter being used. Fig. 3 (not shown) shows another modification in which the two-phase signals are converted from pulsed to A.C. form in band-pass filters before comparison, the comparator yielding a D.C. correcting voltage which is smoothed in a low-pass filter and chopped before use.

Filed: 1937-07-21
Abstract: 480,085. Ornamenting and colouring metals. HUTTENWERKE SIEGERLAND AKT.-GES. July 21, 1937, No. 20193. Convention date, Oct. 13, 1936. Drawings to Specification. [Class 93] [Also in Group XVI] Sheets of zinc-coated metal are treated, as by spraying, with colouring-material immediately after coating with zinc and before the zinc has completely cooled. The position of the spraying is selected so that the colouring-material is retained by the unhardened zinc or that the temperature is such as to ensure burning-in of the colour. The colouring-material, which may be in solution or in the form of undissolved powdered material such as tile or slate dust, fine sand, or the like, is sprayed from a pistol displaceable on a guide arranged transversely above the conveyer for the sheet-metal alternatively, a number of spraying-pistols may be carried by the guide at such distances apart that the whole of the metal is evenly sprayed. The guide is arranged to be longitudinally adjustable to enable spraying to be effected at the correct temperature of the moving metal. Stripping-off means may be arranged above the sheet-metal, and movable or adapted to be pressed unevenly against the metal, or the pistols may be irregularly movable or supplied with differently-coloured materials, in order that irregular colours with a camouflage effect may be produced.

Title: Data processing systems
IPC: G06F9/44
Filed: 1976-05-17
Abstract: The switching system has a chip which is integrated in semiconductor technology and which has an operation register (SR, ZR) which is usable for the mode of operation in the chip and into which register information comprising a plurality of bits is entered which helps to define this mode of operation. The chip which interworks with further chips of the control device is set to the operational characteristics of other chips before the respective commissioning of the system through the input of register information into the operation register (SR, ZR). With the respective commissioning of the control device (ALS) through the application of the operating voltage, register information can be set in the operation register (SR, ZR) which effects a mode of operation in which interworking with chips with different modes of operation is possible. The longest provided work cycle or the most favourable signal level for the transmission of information can thereby be taken into consideration. <IMAGE>

Filed: 1929-07-03
Abstract: 315,760. Davis Steel Process Corporation. (Assignees of Davis, E. W.). July 17, 1928, [Convention date]. Extracting.-Iron ores are reduced in a reverberatory furnace by treating a mixture of ore, carbon, and slag-forming materials with an oxidizing flame, the temperature at the smelting zone being maintained at or above the point at which the rate of carburization of the reduced metal increases abruptly, and sufficient excess of carbon being present to protect the reduced metal from reoxidation. The observed temperature on the surface of the bath may be about 1550‹ C. and that in the smelting and carburizing zone about 1250-1350‹ C. A suitable excess of carbon is introduced with the charge, and a protective layer of carbon is maintained on the surface of the bath, which prevents oxidation and effects carburization of the metal.

Abstract: 658,371. Grading gravel. SUNDSTROM, H. Aug. 9, 1949, No. 20721. [Class 117] In a portable apparatus for grading material in its passage from a gravel-pit to a crusher, the material is drawn from the pit by a bucket 3 over an inclined bridge 2, formed of spaced rods to reject boulders too big for the crusher, to the top of a tower 1. As shown in Fig. 1, the apparatus comprises two (or more) sieves 6, 7 formed of parallel bars, the upper sieve 6 retaining stones too large for the crusher which are collected on a platform 10 for breaking to suitable size. The mesh of seive 7 is such as to pass the material suitable for the crusher on to a shoot 11 leading to the crusher. The finer material passing through the sieve 7 is collected in a pocket 8 from which it is directed by a shoot 12 to a pit for further grading. To secure a uniform delivery from the pocket 8, a feed-device is fitted between the latter and the shoot 12. This comprises a slightlyinclined shoot 13 which is given a jigging movement about a pin 14 by means of a link 15 having its lower end pivoted on the framing at 16 and its upper end connected by a link 17 to an eccentric 18 on the end of the crusher-shaft 19.

The material passing through screen 20 is directed by baffles 21 to a conveyer elevator 22. Material passing from the output 23 of the crusher is carried by a conveyer 24 for regrading on the screen 20. The latter, which is suspended on pendulums 33 is rocked by an eccentric-rod 32 geared to the crushershaft.
