IPC: D01D5/06
Abstract: 1,051,472. Regenerated cellulose filaments. FMC CORPORATION. Feb. 6, 1964 [Feb. 26, 1963], No. 5106/64. Heading B5B. Regenerated cellulose filaments or fibres are made by extruding viscose containing an amino viscose additive that reacts with sulphur and zinc to form a water-insoluble and alkalineinsoluble amino-sulphur-zinc compound into a spinning bath containing sulphuric acid, sodium sulphate and at least 0À02% by weight zinc sulphate (ZnSO 4 ), and subjecting the filaments or fibres to a dilute acid solution, especially a sulphuric acid solution, before drying to dissolve and remove from the filaments or fibres the omino-sulphur-zinc compound. The additive may be a monoamine, e.g. dimethyl-amine (forming zinc dimethyl dithiocarbamate) or diethylamine, diamines, e.g. ethylene diamine, or other polyamines, e.g. diethylene triamine, and may be used in proportions of 1-4% by weight, based on the cellulose, either alone or in combination with other viscose additives, e.g. condensation products of ethylene oxide and phenol and polyoxyethylene glycols. Preferably, the viscose used contains 4-9% cellulose, 5-10% caustic soda and 30-38% carbon disulphide, based on the cellulose, and is spun at a sodium chloride salt point of 2-17, especially 7-12, into a bath containing 5-10% by weight sulphuric acid, 9-20% anhydrous sodium sulphate and 0À02-9%, especially 2À5-7%, anhydrous zinc sulphate, and at a temperature of 10-40‹ C. The fibres formed may be withdrawn from the spinning bath and stretched to a stretch ratio of 1À8 to 2À6, preferably 2À25 to 2À6, while passing through a hot dilute cascade acid bath containing about 3% by weight sulphuric acid, 5% anhydrous sodium sulphate and 1À5% anhydrous zinc sulphate and at 85-100‹ C. using a spinning speed of 20-40 metres per min. The stretched fibres may then be cut into staple fibre lengths, and before drying and preferably immediately after cutting, treated with dilute acid under conditions such as to dissolve any reaction product or complex of the amino viscose additive and the sulphur and zinc present in the spinning operation. Suitably a 0À2 to 1À4% by weight sulphuric acid solution at a temperature of 96‹ C. may be used the treatment time being 15 minutes. Hydrochloric acid, and other inorganic and organic acids may replace the sulphuric acid. The fibres are then drained, washed, bleached, desulphurized, and dried in conventional manner. Such fibres are relatively non-fibrillatable, have a wet modulus of at least 10, preferably between 10 and 20, a water flow number of less than 25, and filaments or fibres of 1À5 denier and 39À7 mm. length have a card load factor of less than 3À25. Fibres so made resemble cotton in wet modulus, shrinkage characteristics and ultimate elongation in the wet and conditional states, but resemble conventional viscose rayon fibres with respect to lustre, softness and hand.

Abstract: 1,234,473. Cathode-ray tube displays. INTERNATIONAL BUSINESS MACHINES CORP. 16 July, 1968 [8 Aug., 1967], No. 33824/68. Heading H4T. In a display control arrangement connected between a plurality of similar electronic display units 1, 2 ... N (Fig. 1A) and a data source 11 emitting data defining the displays to be produced the data for each display are transferred successively from respective input registers TREG1, TREG2 . . . TREGN to a data register REGA at intervals shorter than the longest time required to trace a segment of the character forming the display and thence to a decoder and end point generator 28 which generates signals controlling the display of a single segment the same contents of the data register being applied repeatedly to the decoder, until a complete character has been displayed, under the control of logic circuitry 14 (Fig. 1B) which is arranged to count the number of times a data word defining a character to be dipslayed by the associated display unit is applied to decoder &c. 28. The source 11 (e.g. a computer, magnetic core buffer &c.) supplies image data for each display as a variable length sequence which, in the case of Alpha-Numeric symbols, comprises two byte binary coded data words each byte defining a symbol having between one and nine segments and in the case of graphic data, comprises two words (four bytes) for each segment of the image. The Alpha-Numeric symbols are produced, as described above, by means of the decoder and end-point generators 28 (which may be identical to those disclosed in Specification 1,078,545) generator 28 being controlled by the appropriate logic control unit 14 which also controls the transfer of data to a common output register 22 and thence via respective output registers REG1, REG2 . . . REGN to the associated display units 1, 2 ... N. When graphic data is being displayed the generator 28 is not required and the data is transferred from REGA to the register 22 via a By-Pass register 20 which serves to equalize the delay time in both paths. In the operation of the present embodiment the outputs of registers TREG1, TREG2 . . . TREGN are successively transferred to register A during intervals which are one-third the length of the longest time required to trace a character segment and the interval between transferring the outputs from the registers TREG1, TREG2 . . . TREGN and entering such outputs in registers REG1, REG2 . . . REGN is equal to the longest time required to trace a character segment. Additionally, the time - sharing arrangement employed is such that three display units may be operated simultaneously. The stated advantage of the invention is that the computer &c. does not have to operate as a character generator per se and the time-sharing arrangement employed allows a large number of displays to be serviced without flicker. Details of the clock 16, one of the logic control units 14 and the roller 18 are given with reference to Figs. 2, 3A, 3B and 4 respectively (not shown).

Abstract: 1,239,166. Condenser systems; separation of gasoline from petroleum gas. BERTIN & CIE and ENTREPRISE DE RECHERCHES ET D'ACTIVITES PETROLIERES-ELF. 24 July, 1969 [5 Aug., 1968; 6 June, 1969], No. 37311/ 69. Heading B1B. [Also in Divisions F4 and G3] A pulsed gas flow cooling device (see Division F4) may be used to condense gasoline from gas leaving an oil well. The gas may simply pass through a single device, condensate being subsequently removed from the cooled gas stream, Fig. 14 (not shown). Alternatively, gas passing to the device may be cooled by indirect heat exchange with a branched stream of cooled gas leaving the device, Fig. 15 (not shown). Condensate is removed from the branched stream and from the main stream upstream of the device. In a further arrangement, Fig. 16 (not shown), the main stream does not pass through a device but is cooled by a branched stream which has passed through a series of devices. As illustrated in Fig. 17, gas is introduced at 32 into a cooling device 122. Cooled gas passes from the device at 48 and its condensate collects at 124 to be drained by a constant level valve 126. Gas passes through a constant pressure valve 128 to precool the main stream at 129. Any condensate in the main stream is drained from a point 130. A coil 135 fed from the main gas line may be used to heat the gasoline if it should be undesirably viscous.

Abstract: 1,258,113. Bulk effect oscillators. WESTERN ELECTRIC CO. Inc. 25 Sept., 1969 [25 Sept., 1968], No. 47163/69. Heading H3T. [Also in Division H1] An oscillator has a bulk effect device 12 and means 18, 19, 21-25 for periodically producing, in synchronism with the periodic propagation of a domain in the device, a depletion region in the device to reduce the effective cross-sectional area of the current as and through which the domain propagation occurs. The output efficiency of the oscillator is increased by connecting a circuit 21 to 25 to modulating contacts 18, 19 of the device 12 so as to be series resonant at the domain 17 propagating frequency. The contact 19 is an ohmic contact whereas contact 18 is formed as a rectifying junction to the wafer 12 of the device and may be a Schottky barrier PN junction or metal oxide semi-conductor contact. The oscillating voltage of the series resonant circuit 18, 19, 21-25 leads the current through the device by 90 degrees and for a N-type GaAs wafer 12 the negative half cycles of the oscillating voltage forward bias the Schottky barrier contact 18 and produce a depletion region 27 near this contact 18. This reduces the current (33, Fig. 2C, not shown), while the domain is propagating the depletion region 27 so as to effectively restrict the cross-sectional area of the wafer 12. In another embodiment two Schottky barrier contacts (36 and 37, Fig. 3, not shown) are provided on the device (38) and the series resonant circuit consists of inductor (41) the capacitance between contacts (36, 40 and 40- 37) and inductor (42). The voltage between ohmic contact (40) and Schottky barrier contact (37) is 180 degrees out of phase with respect to the voltage between ohmic contact (40) and Schottky barrier contact (36) which periodically produces depletion regions which further reduces the current through the device (38) to give the output characteristic (33<SP>1</SP>, Fig. 2C, not shown). As an alternative to the modulating contacts 18, 19 the depletion region may be produced by periodic illumination of the wafer 12. The Specification states that it is known to cool a bulk effect oscillator by liquid nitrogen to increase the oscillator efficiency.

Abstract: 1,258,630. Acoustic devices. WESTERN ELECTRIC CO. Inc. 1 May, 1969 [3 May, 1968], No. 22197/69. Heading H3U. In an acoustic wave transmission device including two bodies having a common interface and composed of materials having different acoustic properties, the wave path through one of the bodies is caused to make an incident angle # i  with a normal to the interface where: and providing also that the following conditions are satisfied p 1 , p 2 , v 1  and v 2  representing the relative densities and acoustic velocities of the two media. Theory described in the Specification shows that by calculating # i  in this manner an acoustic equivalent of the optical Brewster angle is obtained whereby loss of acoustic energy due to reflection at the interface is negligible. The device shown in Fig. 4 comprises a fused quartz body 41 having a common interface with a sapphire body 42. Shear waves in a path As derived from a quartz transducer 40 make an angle # i =39À1 degrees with a normal to the interface. Since # t  may be calculated and is found to be equal to 73À6 degrees. The invention is applicable to delay lines, acoustic wave amplifiers and acousto optic devices for light modulation.

In a gear-hobbing machine the hob slide 17 slides in a guideway 16 which is set at an angle B to the vertical, so that the slide always rests on the faces 25, 26, in the guideway. If the hob is not in cutting engagement with the work, then the force which pushes the slide into these faces is the weight of the slide P 1 . When hobbing is taking place the force PR is the resultant of the weight P 1 , and the force P 2  due to cutting. In either case the forces P 1 , or P R  must pass through the back face 21 of the guide, and therefore angle B must be greater than the friction angle Q obtained by the co-efficient of friction between the slide 17 and guideway 16. The guideway may be of the Fig. 3 or Fig. 4 form (not shown). 'Guideway 16 is provided in a plate 15 which can swivel in a carriage 14, about an axis normal to 'that of the workpiece W, and the workpiece is mounted between a headstock and tailstock 12, 13.
