Title: Reducing the dirt adsorption of binder-containing pigment dyeings and prints on fibrous materials
IPC: D06P1/44
Filed: 1968-12-23
Abstract: 1,240,509. Pigment dyeing. BADISCHE ANILIN-& SODA FABRIK A.G. 23 Dec., 1968 [22 Dec., 1967], No. 60980/68. Heading D1B.

Title: Centrifuge
Inventor: BLACKFORD JOHN EDWIN
IPC: B04B5/08
Filed: 1968-12-23
Abstract: 1,269,219. Centrifugal separator. JOSEPH LUCAS (INDUSTRIES) Ltd. 19 Dec., 1969 [23 Dec., 1968], No. 60991/68. Heading B2P. A centrifuge for separating gases of different molecular weights comprises a chamber 1 having an inlet 14 and a first outlet 3 and a rotatable drum 6 carried within the chamber on gas bearings 4, 8 and defining with the chamber an annular space having at one end a constricted cross-section 9 which communicates with a second outlet 13 in the chamber. The drum 6 is driven by a turbine via a shaft 16. Holes 11 are provided in the wall of the drum at its maximum diameter and fixed vanes 12 are fitted in the annular space adjacent the holes. In operation, the drum is rotated and the mixture of gases to be separated is fed through an inlet 14 into a volute chamber 15 where it acquires an angular velocity equal to that of the drum. The mixture there passes through the drum and in so doing the heavier gas particles separate against the wall of the drum and are ejected through the holes 11 into the annular space, the vanes 12 preventing further rotation of the heavier gas in this space. A small proportion of the heavier gas leaks past the bearing 8 to enter the gas mixture in the volute 15 and again pass down the drum 6. The remainder of the heavier gas passes through the small clearance 9 of the annular space to an annular chamber 10 and thence through the outlet 13. The clearance 9 causes a pressure drop in the gas as it enters the annular chamber 10. The lighter gas particles are discharged through the outlet 3 and a small portion of the lighter gas flows past the bearing 4 into the chamber 10 due to the lower pressure existing in the latter. In an alternative arrangement, one or both of the bearings 4, 8 may be gas-bearings of the pressure-fed type.

Title: Process for the selective sorption of paraffins and/or olefins from mixtures with aromatic hydrocarbons
Inventor: EBERLY PAUL EARL JR
IPC: C10G25/03
Filed: 1968-12-30
Abstract: 1,246,852. Al removal from mordenite. ESSO RESEARCH & ENG. CO. 30 Dec., 1968 [18 Jan., 1968], No. 61682/68. Heading C1A. [Also in Divisions B and C5] A bed of aluminium-deficient mordenite having a molar ratio SiO 2  : Al 2 O 3  >25 : 1 and preferably >65 : 1, is used to separate paraffins and/or substituted or unsubstituted olefins from mixtures with substituted or unsubstituted aromatics by adsorption of the paraffins and/or olefins. The aluminium deficient mordenite is suitably prepared by boiling mordenite with strong mineral acid of 1-6 N, followed by drying at 200-1200‹ F.; in the extreme case, all the aluminium is removed leaving a highly crystalline form of silicon. The separation is preferably carried out in the vapour phase the temperature of the mixture being maintained near to the boiling point. Regeneration and desorption of the bed may be accomplished by any conventional process, but steam desorption which causes no degradation up to 800‹ F. is favoured; in the examples, desorption is achieved with a water-saturated stream of helium at 200-500‹ F., the bed thereafter being dried for reuse with helium at 800‹ F.

Title: Adjustable resistors for hybrid circuits
IPC: H01C17/23
Filed: 1978-07-03
Abstract: High precision film resistors are designed as a main resistive element 3 corresponding to half the total value associated with five additional resistive elements the values of each of which are successively half of the value of the preceding one plus one resistive element of the same value as the smallest element of the five above mentioned elements. Each of the additional elements is originally short-circuited, adjustment being performed by cancelling at least one of the short- circuits. This design of the resistive elements allows a more reduced number of short-circuit suppressions than previously used designs with the same precision. Further adjustment is achieved by forming a groove 9 in part 8 of main element 3. <IMAGE>

Title: Methods and apparatus for encoding and constructing signals
IPC: G10L25/00
Filed: 1979-03-29
Abstract: Methods and apparatus are described for encoding electrical signals for transmission in a narrow frequency band or at a low bit rate and for constructing signals from encoded signals in which a succession of first signals A representing the durations of sub-divisions, for example, half cycles of the signal to be encoded are generated as is a succession of second signals C representing the shape of the sub-divisions. Each pair of first and second signals may then be replaced by one of a limited number of symbols. After an operation such as transmission to a remote location, or removal or addition of symbols, the symbols are translated back into first and second signals. Whether transmitted or from a store, the first and second signals are used to construct analogue signals having sub-divisions of duration derived from the first signals and shapes derived from the second signals. <IMAGE>
