Title: Improvements in processes for shrinking textile materials having a basis of organic derivatives of cellulose
IPC: D06M13/127
Filed: 1941-09-19
Abstract: 553,236. Shrinking textiles formed from cellulose derivatives. BRITISH CELANESE, Ltd. Sept. 19, 1941, No. 12083. Convention date, May 15. [Class 2 (ii)] Threads, yarns, ribbons, and fabrics having a basis of an organic derivative of cellulose are shrunk by subjecting them to the action of a solution of acetaldehyde in a liquid hydrocarbon, preferably xylene. The treatment may be effected under tension. Other hydrocarbons mentioned are benzene, toluene, and kerosine which may be present in the proportion of 25 to 100 per cent. of the acetaldehyde used. The extent of the shrinking action is regulated by variations in the proportion of solvent and in the time of treatment. A recommended treatment is by a solution of equal volumes of cetaldehyde and xylene at from 0 to 20‹C. employing a contact time of from 1 second to 2 minutes. In the case of treating fabrics, the material may be drawn through the liquid under rollers in a trough provided with a hood to minimize evaporation and is then carried by a travelling belt through an evaporating zone. Figs. 2 and 3 show an apparatus for treating yarn in which the yarn is first passed through the shrinking liquid in a vessel 18<SP>1</SP> heated or cooled by a jacket 22, and then through an evaporating chamber 26 through which air is circulated and then passed into a solvent recovering plant. In examples of the treatment of yarn, the yarn is passed through the solution at a speed of 100 yards per minute. The extensibility of the products is found to increase from 10 to 39 per cent. The process may be applied to textiles of cellulose acetate or other esters and also to those of cellulose ethers such as ethyl cellulose and benzyl cellulose. Specifications 359,971 and 545, 422 are referred to.

Abstract: 808,345. Centrifugal casting-machines. HERMAN PNEUMATIC MACHINE CO. April 27 1955 [May 5, 1954], No. 12136/58. Class 83 (1). In a centrifugal casting-machine, a carriage carrying a core-holder is movable to position a core thereon within the open end of a rotatable mould, and a pouring-spout on the carriage projects through the core and its holder. A core 102, Figs. 3 and 4, is mounted on a holder 91 rotatable in bearings 105 in a bracket 98 carried by the carriage 77, and two pneumatic cylinders 92 on the carriage have pistons attached to the bracket 98, so that the core-holder may yield slightly when the carriage is fed against a stop, to apply the core to the mould 16 in a flask 16<SP>1</SP>, as in Fig. 4, and thus inhibits damage to the core and mould. Resilient material 101 is preferably applied between the core 102 and its holder 91 to allow for lack of concentricity of the core and mould during rotation. The carriage 77 has a bearing 79 for supporting a mandrel 25, Fig. 3, which is used for forming the mould 16, as described in Specification 808,347, and after formation of the mould, the carriage 77 is rotated to the Fig. 4 position to apply core 102 and allow metal to be poured from a ladle 103, through a spout 100 projecting through the core, into the mould. Simultaneously with the application of core 102 at one end of the mould, a core 53a, Fig. 1, is applied to the other end. The machine described has two parallel flasks and moulds 16, 16<SP>1</SP>, and the cores 53a are carried by the plungers 53 of fluid-pressure cylinders 52 mounted on a U-shaped frame 49 which is pivoted on trunnions 48. When the mandrels 25 are inserted into the flasks, frame 49 is rotated about the trunnions 48 by fluidmotors 47 to a vertical position, to allow the mandrels to pass. After withdrawal of the mandrels, the frame 49 is returned to the horizontal position shown and cores 53a are advanced by plungers 53 to enter the moulds. After pouring and centrifuging, the flasks are moved to an upright position for dicharge of the moulds and castings. Other features of the machine are described in Specification 808,348.

Title: Improvements in room heating elements
IPC: H05B3/34
Filed: 1959-04-13
Abstract: 863,928. Electric heating resistances. NORSK ESWA A.S. April 13, 1959 [Aug. 4, 1958], No. 12474/59. Class 39(3). A flat electrical heating element, for mounting in or adjacent room-confining surfaces in buildings, comprises a heating resistor in the form of a strip of metal foil 5 having a co-extensive backing 6 of flexible insulating sheet material, e.g. paper, arranged in a tortuous path and glued to a supporting sheet 1 of flexible, insulating material, preferably with a slow-setting or pressure- or heatsensitive glue. The resistor strip may be produced by glueing together large sheets of foil and paper and then cutting them into strips of the desired width. As shown, in the longer stretches of the tortuous path the foil 5 faces the supporting sheet 1 which may be kraft paper coated with a moisture resistant lacquer or a flexible artificial plastic material. The foil of thickness 0.015 mm. may be of a lead-tin alloy having a melting point of 220 ‹C. and a resistivity of 0.15 ohm mm<SP>2</SP>/m. The ends of the foil are soldered to brass terminals 13 mounted on an insulating strip 16. A covering sheet 4 is secured at intervals to the edges of sheet 1 or the sheet 1 and resistor may be protected by a coating of insulating, waterproof lacquer, with or without a sheet of crepe paper. Alternatively the element may be inserted into a flat sack of flexible waterproof plastic or one side of such a sack may constitute the supporting sheet 1, the sack being turned inside out after the foil has been glued thereto. The marginal areas 7 and one or more intermediate areas 8 of the sheet 1 are free of resistor strip to enable the element to be secured to building structures, e.g. ceiling laths, the element being covered in by panelling (see Group X).
Patent GB-328779-A (GB)
IPC: H04B3/20
Filed: 1929-04-22
Abstract: 328,779. Staat der Nederlanden. Nov. 23, 1928, [Convention date]. T w o - w a y repeating systems. - In echo-suppressing arrangements for use, e.g. in a two-way amplifier or in a telephone system with one or more radio links, the echo-suppressors are controlled bv an auxiliarv current or currents in turn controlled by the speech h currents, the auxiliary current or currents flowing during the intervals between speech or during actual speech, or, in some cases, during both. The Figure shows a two-way arrangement associating a terminal line 1 with the transmitting and receiving stations of a radio link, the auxiliary current being alternating current of a high audible frequency, e.g. 2800. When no speech is being received over line 16, the auxiliary current flows and passes through a filter 7 and rectifier 8 to control the echo suppressors 6, 9 in such a way that the transmitting path 2 - - 3 is open but the receiving path 16 - - 2 is closed. When speech currents arrive over line 16, the removal of the auxiliary current causes the path 16 - - 1 to be opened and the path 2 - - 3 to be closed so that the incoming speech currents pass to line 1 through amplifiers 15, 18 and a low-pass filter 17 which passes all frequencies below that of the auxiliary current. At the transmitting end, the auxiliary current is normally supplied to the radio transmitter over apparatus 12 and line 3, but when speech arrives from line 1 part of it passes to a rectifier 11 and thereby controls the apparatus 12 to suppress the auxiliary current. Alternatively, the auxiliary current may flow during speech and be suppressed during pauses, or currents of two different frequencies may flow during speech and pauses, respectively. In systems without a radio-link, the auxiliary current may be a direct current flowing in different directions during the talking and silent periods. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the alteration of the strength in addition to change of direction of the auxiliary current in systems without a radio link and using direct current. This subjectmatter does not appear in the Specification as accepted.
