Title: New dyeing process for aromatic polyester/cellulose unions
Inventor: DENYER RONALD LEONARD
IPC: D06P3/82
Filed: 1964-12-04
Abstract: Union fabrics of aromatic polyester and cellulose fibres are dyed by first dyeing with a reactive dye and thereafter dyeing with a disperse dye in each case by a method known from the literature or used in practice.  The first stage may be carried out by dyeing on the jig or winch or padding followed by heating or preferably by padding with an alkaline solution of reactive dye, if desired containing adjuvents, e.g. anionic or non-ionic wetting agents and migration inhibitors then storing the moist fabric at ambient temperature.  The second dyeing step may be preceded by washing but this is usually effected simultaneously with the dyeing itself.  The disperse dyes may be applied at 85-150 DEG C. with or without carriers together with usual adjuvents, e.g. anti-foam agents, anionic wetting agents, sequestering agents and acids or alkalis. Examples of union-and cross-dyeing are given.

Patent GB-501013-A (GB)
Abstract: 501,013. Steel manufacture. ROCH. LING'SCHE EISEN-UND STAHLWERKE GES. Aug. 16, 1937, No. 22451. Convention date, April 2. [Class 72] Steel low in phosphorous and sulphur is produced by intimately mixing ordinary steel with a basic liquid slag poor in phosphorus, sulphur and silicon dioxide obtained from a Siemens Martin process. The steel may be mechanically admixed with the slag from the same furnace after they have been separately tapped, being for example allowed to flow in a large jet into a ladle into which the whole or a portion of the slag has been previously tapped. Alternatively, the slag and steel may be admixed by running them together into the ladle. Alkalis, particularly strontium and barium compounds, and if desired fluorspar, may be added to the slag before use. Lime may be added before tapping the furnace to increase the fluidity of the slag. The process may be used to shorten the period of treatment in the furnace in cases where it is not desired to lower the phosphorus and sulphur contents of the steel considerably below the normal. Specifications 21963/05, [Class 72], and 455,042, are referred to.

Filed: 1972-11-02
Abstract: 1405789 Electroacoustic transducer KUREHA KAGAKU KOGYO KK 2 Nov 1972 [4 Nov 1971] 50637/72 Heading H4J An electroacoustic transducer which relies upon both capacitor and piezoelectric effects has a vibratory diaphragm 12 (Fig. 4-1) of piezoelectric polymer which develops expansion and contraction movements parallel to its faces when an alternating potential difference is applied to two electrodes 13, 13<SP>1</SP> one on each face. A fixed electrode 11 is located in spaced relation to the diaphragm 12. When an input signal is applied between the two electrodes on the diaphragm 2 and between the fixed electrode 11 and the nearer electrode 13<SP>1</SP> on the diaphragm 12a combination, additive, vibration of the diaphragm 12 is caused by the piezoelectric effect of the diaphragm 12 and by the attractive and repulsive forces between the fixed electrode 11 and the nearer electrode 13<SP>1</SP> on the diaphragm 12. Preferably the fixed electrode 11 carries an electret 10. If not, a polarization potential is applied between the fixed electrode 11 and the nearer electrode 13<SP>1</SP> of the diaphragm 12. The diaphragm 12 is curved, even in its contracted state. In some arrangements it may be fixed locally, e.g. at a central point thereof. The transducer may be used in headphones, loudspeakers, microphones and pickups.  A push-pull transducer (Fig. 5) has a piezoelectric polymer film diaphragm 12 electroded on both sides. Two fixed electrodes 9, 9<SP>1</SP> each have an electret confronting the diaphragm 12. The secondary of a transformer 15 has one tap connected to one fixed electrode 9 and to the remote electrode on the diaphragm 12 and the other tap connected to the other fixed electrode 9<SP>1</SP> and to the remote electrode on the diaphragm 12. A headphone (Fig. 8) comprises an aluminium electrode 11 with an electret 10 spaced from a piezoelectric polymer diaphragm 12 having electrodes on its opposite sides. A signal source is connected between the electrode 11 and a diaphragm electrode and between the two electrodes on the diaphragm. A transformer is unnecessary for normal use. The piezoelectric polymer is preferably formed from a polyvinylidene fluoride or a copolymer of vinylidene fluoride and at least one monomer copolymerizable with vinylidene fluoride. Alternative polymers are vinylidene chloride resin, vinyl fluoride resin, or vinyl chloride resin. A non-oriented film may be used after being subjected to a D.C. field at elevated temperature. The non-oriented film may be axially oriented, by stretching, before application of the D.C. field. The electret, if used, is preferably made from 70% by weight polyvinylidene chloride, balance polymethyl methacrylate. The electret properties are obtained by treating the polymer sheet for 30 mine. under the application of a D.C. field of 1000 kV/cm. at 90 C. and then cooling to room temperature.
