Title: Process for the separating of a liquid constituent from a homogeneous liquid mixture
IPC: C07C47/06
Filed: 1945-08-10
Abstract: Paraldehyde or other derivative of acetaldehyde such as an acetal is separated from a mixture thereof with one or more liquids in which it is soluble, such as water, alcohol or acetaldehyde, by multiple extraction with a solvent for said latter liquids, but in which the desired liquid is of low solubility, each extraction treatment being carried out for a shorter time and with a smaller amount of solvent than necessary to attain the limit at which dissolution of said desired constituent begins.  Advantageously, the conditions are determined to be as near as possible to this limit.  The mixture may be stirred with 5-50 per cent by volume of solvent for 2-15 mins., allowed to stand for an equal time, the two layers separated, and that containing the desired constituent again subjected to the treatment.  The total number of treatments may be 4-10.  The solvent may be a liquid already present in the mixture, for example water. In examples: (1) 1 volume of a mixture of diethyl acetal with acetaldehyde, ethyl alcohol, and water is stirred with 0.14 volumes of water for 5 mins., stratified for 2 mins., and the operation repeated 6 times on the upper layer giving 98 per cent acetal; (2) 1 volume of paraldehyde mixed with ethyl alcohol, acetaldehyde, and water is treated with 0.4 volumes of water for 10 mins., stratified for 15 mins., and the upper layer extracted 4 times each with 0.2 volumes of water. Specification 607,130 is referred to.  The Specification as open to inspection under Sect. 91 specifies also aldol, chloroform, bromoform and aminobenzaldehydes as substances which may be separated from their mixtures.  An example describes the separation of bromoform from alcohol.  This subject-matter does not appear in the Specification as accepted.

Title: Yarn Packages
Inventor: MORRIS GWYNFRYN JOHN
IPC: B65H55/04
Filed: 1967-05-04
Abstract: 1,198,077. Building yarn package. IMPERIAL CHEMICAL INDUSTRIES Ltd. 23 April, 1968 [4 May. 1967]. No. 20725/67. Heading B8M. To ensure that the mean over-end take-off tension of a yarn package is made more nearly uniform the package is built by traverse strokes such that in an early traverse stroke at least 58% of the yarn is laid on the take-off side of the mid point of the full package such percentage being reduced during at least part of the build; in addition the traverse reversal points at the package end opposite the take-off end are moved progressively towards the take-off end during the building of at least the last three quarters of the package. The early traverse stroke may be the first stroke but must be performed before 5% of the full package has been built. The desired distribution of yarn may be produced by varying the traverse speed within an individual stroke, decelerating the traverse towards the take-off end and accelerating it when moving in the reverse direction. Examples are given with full numerical data.

Abstract: 903,198. Life-saving equipment. SCHERMULY PISTON ROCKET APPARATUS Ltd. June 1, 1961 [June 14, 1960], No. 20797/60. Class 77. [Also in Group XXVIII] A life-saving appliance comprises in combination, a sectional container, an inflatable member adapted when deflated to be stored within the container, inflation means directly connected to the member and actuable in response to contact with water, and a rocket attached to the container and adapted to propel the container through the air. A life-belt 50, Fig. 4, inflated by a bottle 12 of compressed gas attached thereto which is released by an initiator 13 responsive to contact with water, is carried in a deflated state in a water-permeable nylon bag within a container 2, Fig. 1, formed of sections 3, 4, pivoted at 6, 7 on a base plug 5, the container being propelled through the air by a conventional line-throwing rocket 1 attached thereto. In the inoperative condition the sections 3, 4 of the container are retained in position by adhesive tape 10 of a type suffering a marked reduction of adhesive property on contact with water, and a removable plug 8 with an orifice closes the top of the container. A length of cord 14 connects the life-belt with the plug 5 so that the rocket and container act as a stabilizer in the water and a flaked line 46 is attached to the pivoted end 47 of a yoke 48 of the rocket, which line may be buoyant. The initiator 13 comprises a a three-part casing 18, 19, 20, Fig. 3. The part 18 engages the screw-threaded end 21 of a gas bottle 21 and has a stem 22 for connection to the life-belt. The part 19 houses a slidable spring-urged tool 27 for fracturing a frangible diaphragm 26 of the bottle, which tool is retained in position by a ring 34. The spring 29 also urges balls 32 which engage an inclined face 33 of the ring 34 radially inwardly through apertures in a sleeved end 30 of the tool to engage a shaft 35 projecting thereinto. The cup-shaped part 20 of the casing houses the end of the shaft 35 which is secured to a disc 43 and surrounded by a washer 44 of compressed and treated sponge. Absorbtion of liquid entering the part 20 through apertures 39 and a perforated disc 40 therein causes sufficient swelling of the washer to move the disc 43 from the part 19 and remove the shaft 35 from the sleeved end of the tool 27. When a shoulder 37 of the shaft is drawn past the balls 32 they move radially inwards to free the tool from retention by the ring 34 to puncture the diaphragm 26. Specification 854,003 is referred to.

Title: Improvements in and relating to the control of electrically operated soot blowers
IPC: F28G15/00
Filed: 1947-08-01
Abstract: 669,388. Control Of Several motors. BRITISH THOMSON-HOUSTON CO., Ltd., and JEFFERSON, H. F. Dec. 9, 1948. [ Aug. 1, 1947] No. 21097/47. Class 38 (iii). [Also in Group XXXV] An electrical circuit for the control of the sequence of a number of electrically-operable soot-blower heads of the type described in Specification 669,387, [Group XXVIII], comprises a single solenoid-operable multi-position multi-contact switch. As shown, the switch S is of the type in which the energization of a solenoid draws a pawl over the teeth of a ratchet wheel coupled to the moving contacts, the pawl engaging the teeth on its spring-actuated return movement, when the solenoid is deenergized, thus stepping the moving contacts on to the next row of fixed contacts. The switch is provided with two rows of fixed contacts. The heads are driven by three-phase motors under the control of contactors having coils 1, 2, 3, 4 and contacts A1, A2, A3, A4. A timing relay T prevents a head from blowing steam for an excessive period in the event of a mechanical fault. Automatic operation is provided by movement of a master switch MS to an appropriate position in which a main contactor is closed and the coil S1 of switch S energized. Release of the handle of the master switch allows return movement to an intermediate position in which the coil S1 is deenergized, the switch S1 being stepped on to contacts S1a, S1b, so energizing contactor 1. When the first head moves it closes a limit switch LS1 to re-energize the coil S1 which is de-energized when the head completes its operation. The switch S is then stepped on to the next row of contacts to stop the first head and start the second. Subsequent operation is similar until the switch S passes on to contact S5b when it is automatically returned to its original position. One of the heads may be omitted from the sequence by operation of the appropriate switch CS1, CS2, CS3, or CS4. One head may be operated alone by manual operation of a switch SET and movement of the switch MS to the "hand" side. The operation of the equipment may be rendered ineffective unless all the heads are in the correct position for starting, Fig. 2 (not shown). Indicating lamps and alarms are provided.

Abstract: 771,276. Colour television. PHILCO CORPORATION.' July 21, 1955 [July 21, 1954] No. 21132/55. Class 40 (3). A colour television signal according to the American N.T.S.C. standards is produced at a transmitter, Fig. 1, by an arrangement utilizing three sub-carrier modulators 22, 23, 24 instead of the normal two I and Q signal modulators. Modulators 22 and 23 operate with sub-carrier signals lagging respectively by 90 and 180 degrees on the reference burst and receive 0-0.6 Mc/sec. portions of colour-difference signals R-Y, B-Y whilst modulator 24 operates with a sub-carrier signal at the normal I signal phase (- 57 degrees with respect to the reference burst) and receives via matrix network 25 the 0.6-1.2 Mc/sec. portion of the I signal made up of - .27 (B-Y) +.74 (R-Y). The modulator outputs are then applied to transmitter 32 and combined with the luminance signal Y, the output from modulator 24 being restricted to a single side-band however by filter 34. In effect modulators 22 and 23 in combination produce the Q signal and the 0-0.6 Mc/sec. portion of the I signal by operating at the appropriate phase angles with the colour-difference components of the I and Q signals instead of the actual signals, whilst the remaining 0.6-1.2 Mc/sec. portion of the I signal is added in a conventional manner by modulator 24. The arrangement permits the modulators 22 and 23 producing the important low-frequency chrominance information to operate at sub-carrier angles which are multiples of 90 degree and may thus be maintained with considerable precision. Phase shifter 27 is, for example, simply a phase-inventing vacuum tube circuit, whilst phase-shifter 28 is a socalled quadrature transformer. The invention may be applied to a receiver, Fig. 2 (not shown), three synchronous demodulators being employed instead of the conventional two. The first two operate with the local sub-carrier wave lagging respectively by 90 and 180 degrees and derive 0-0.6 Mc/sec. R-Y and B-Y colourdifference signals, whilst the third operates with the local sub-carrier wave at the I signal phase to derive the 0.6-1.2 Mc/sec. portion of the I signal. Suitable proportions of this signal are then added to the colour-difference signals.
