Title: Improvements in and relating to ironing machines and the preparation of workpieces therefor
IPC: D06F67/04
Filed: 1944-08-30
Abstract: 583,133. Ironing-machines. HAYDOCK, J. Aug. 30, 1944, No. 16499. [Class 138 (ii)] Before flat articles such as sheets and table linens are passed through ironing- machines the hems are pressed between an intermediate fixed buck b and a movable buck a below and a movable head c above, all three being heated and the under surfaces of buck b and head c being smooth and polished and the surfaces of bucks a and b having layers of padding on resilient base. The bottom buck a is supported by two side members d each pivoted to an arm e on a cross shaft f and running on a roller g on an arm h fast to a cross shaft i having an arm j for actuation by a plunger k in a cylinder m supplied with compressed air by a valve n operated by an arm o. Similarly the head c is suspended from two side members p each pivoted to an arm g on a cross shaft r, and forced by a spring s to run on a roller t on an arm u on a cross spindle v having an arm w pivoted to a plunger x in a cylinder y supplied with compressed air through a valve z operated by an arm 2. Pedals 3 and 23 linked to levers 4 and 5 when depressed remove the arms o and 2 from the valves to exhaust the cylinders and ease the pressure above and below the buck b when the head c and buck a can be moved clear of the buck b, a spring 6 expanding between the arms j and w to assist the action. The hems being placed above the bucks a and b, bucks a and c are brought under and over the buck b the belt 11 is made to carry over the work to the cylinders to cause rollers g and t to press the hems, the body of the work piece resting in a trough 8 carried by the. members d and surrounding a cross arm q supported from a spindle 10 which has a pulley 12 acted on by a belt 11 attached to rams in cylinders 13, 14. Thus on freeing the hem between bucks a and b the belt 11 is made to carry over the workpiece on the arm 9 and transfer it to a conveyer 16 which feeds it to the ironing-machine, the hem between bucks b and c being released as the arm 9 completes its travel.

Title: Process for the separation of an organic mixture containing hydrocarbons by means of extractive distillation
IPC: C10G21/00
Filed: 1962-05-07
Abstract: The separation of hydrocarbons by extractive distillation using a selective solvent boiling higher than the mixture is effected so as to obtain overhead at least one more soluble component as well as less soluble components and the overhead is subjected to a selective solvent extraction process.  The extraction is preferably effected without reflux using a sulpholane-type or glycol-type solvent.  The same solvent is preferably used in the solvent extraction. The rich extract may be passed to the solvent stripping zone together with the bottoms from the extractive distillation, or may be returned to the extractive distillation column below the point of introduction of solvent and above the point of introduction of mixture.  The rich extract may first be subjected to flashing, the overhead being returned to the solvent extraction and/or to the extractive distillation.  The separation of olefins from paraffins, aromatics from non-aromatics or heavy aromatics from light aromatics may be effected.  Specifications 625,505 and 764,650 are referred to.

IPC: H04J1/08
Filed: 1963-05-03
Abstract: 998,935. Radio link repeater; channel extraction and insertion. STANDARD TELEPHONES & CABLES Ltd. May 3, 1963 [May 4, 1962], No. 17533/63. Headings H3R and H4L. . In an F.M. frequency division multichannel radio link repeater, the received signal is converted to an intermediate frequency signal which is then translated into a radio frequency band for retransmission and means are provided for extracting a number of the channels at the repeater and inserting other channels in that portion of the transmitted band previously occupied by the extracted channels. The I.F. signal at the output of receiver 10 is coupled to transmitter 11 in which it is translated to a radio frequency band for retransmission and also to a demodulator 12 which supplies a base band output signal from which the frequency band containing the channels to be extracted is selected by filter 13 and applied to a utilization circuit 14. The output of the filter is also applied to a phase inverter 15 which provides an output to modulate the transmitter local oscillator 16 and produce a signal which when combined with the signal produced by translation of the received I.F. signal cancels the sidebands produced by the channels dropped at the repeater. The channel signals to be inserted are applied at terminal 17 and also modulate the transmitter local oscillator 16. The gain of the inverter may be controlled by the output of a comparator 18 to which a pilot signal extracted from the receiver output by filter 19 and from the transmitter output by demodulator 20 and filter 21 are applied. The comparator supplies a D.C. output signal having an amplitude proportional to the amplitude of the pilot signal from filter 21 and a polarity which is a function of the phase difference between its input signals. The inverter is controlled such that zero output is obtained from filter 21.

Abstract: 924,996. Ceramic glasses. ENGLISH ELECTRIC CO. Ltd. Sept. 3, 1959 [June 3, 1958; Feb. 26, 1959], Nos. 17688/58 and 6764/59. Drawings to Specification. Class 56. In the manufacture of ceramic glass articles from glass capable of controlled devitrification, glass batch is used containing a phosphate corresponding to 0.5 to 6.0% by weight of phosphorus pentoxide as a nucleating agent and the article is heat treated to devitrify the glass to a predominantly crystalline ceramic glass material. Preferably a metal phosphate is used, of a metal whose oxide forms a major constituent of the glass batch. Major constituents are given as within the following ranges by weight: SiO2 45 to 88 ; Li2O 0 to 27; MgO 0 to 32; Al2O3 0 to 36. Other constituents are given as follows:-Na2O and/or K2O up to 5; ZnO up to 10; SrO, BaO and/or PbO up to 5; CaO up to 10; B2O3 up to 10. For the nucleating agent, orthophosphates of Li, Mg, Al are preferred but orthophosphates of Ca, Zn, Na or K may be used or meta- or pyro-phosphates of the metals. A proportion of the metallic ion, Li or Mg, may be replaced by ammonium or hydrogen ions. Examples of glasses are given. The melted glass batches are shaped as by casting, pressing, drawing or blowing and they may be annealed if required to store before processing. To form the ceramic glass, the articles are heated at 4-5 C. per minute to the softening point and this temperature is maintained for at least one hour to initiate crystallization. In refractory glasses containing Al2O3, the temperature is then raised at 4-5‹ C. per minute to about 40-50‹ C. above the softening temperature and maintained for at least one hour. In all glasses, the heating is then continued at the same rate to the final crystallization temperature and maintained for at least one hour. Final temperatures are given, for certain compositions, from 850‹ to 1200‹ C. Specification 752,243 is referred to.
