Title: Process for colouring cellulose esters and ethers
IPC: D06P1/00
Filed: 1927-02-25
Abstract: 275,553. Soc. Chimique des Usines du Rh¶ne. Aug. 3, 1926, [Convention date]. Cellulose ester and ether compositions.-Cellulose esters and ethers are coloured for use in the manufacture of solid articles in the manner of celluloid, by forming in a solution in an organic solvent of the ester or ether a dispersed mineral colouring matter, the reagents necessary to the formation of the colouring matter being introduced in aqueous solution, and subsequently precipitating the coloured ester or ether, and washing and drying the coloured product, In examples, into a solution of cellulose acetate in acetone is stirred a solution of ferric chloride and subsequently a solution of potassium ferrocyanide, and the acetate recovered by precipitation with water or by evaporation of the solvent, giving a product coloured blue; cadmium sulphate is stirred into the solution obtained when acetylating cellulose, and a solution of sodium sulphide slowly added, and on precipitation a yellow-coloured cellulose acetate is obtained. The original solution of the cellulose ester or ether may be divided into as many portions as there are reagents, which are introduced singly into these portions, and the several portions are finally mixed together. The coloured cellulose esters and ethers may be mixed with other coloured esters and ethers, and the initial shade mav also be modified by the addition of organic colouring matters. The Specification as open to inspection under Sect. 91 (3) (a) refers to the formation of a mineral colouring matter in the midst of a solution of a cellulose ester or ether; and it includes the recovery of the coloured ester or ether by evaporation of the solvent. This subject-matter does not appear in the Specification as accepted.

Filed: 1968-02-02
Abstract: 1,181,633. Ferrimagnetic waveguide devices. MULLARD Ltd. 2 Feb., 1968, No. 5391/68. Heading H1W. A control device for guided electromagnetic wave energy comprises a ferrite, YIG or other ferrimagnetic element magnetically biased in the general vicinity of a resonance and a control lead so disposed that the element is responsive to the magnetic field of currents in the lead, the conductors of the lead being disposed so as to form a high-frequency transmission line. The control lead is used to switch the element between resonant and non-resonant conditions or to change the phase-shift, both effects being non-reciprocal as regards the transmitted wave. The element 17 may be supported in a rectangular waveguide upon a dielectric vane 19 which serves to concentrate the field in the vicinity of the element. The element may be provided with a jacket (not shown) of material having a dielectric constant equal to that of the ferrimagnetic material. The jacket improves impedance matching. The control lead 18 may take the form of a transmission line having conductors which pass along either side of the element and terminate in a resistive load which may be situated either inside or outside the waveguide. If a coaxial or other transmission line is used (instead of a waveguide) for the controlled wave, then one of the conductors of this line may also constitute a control conductor. The device may be used as an isolator in the receiver circuit of a TR apparatus, the control lead being connected to the control gate of the transmitter. It may also be used in a phaseshift circulator of the type comprising two hybrid devices (e.g. magic T's) coupled by two signal paths, one of which provides non-reciprocal phase-shift.

Title: Improvements in and relating to the production of insulating coatings on silicon steel
IPC: H01B19/04
Filed: 1944-03-27
Abstract: An insulating coating is produced on silicon steel by heating the latter in a reducing atmosphere to form a scale thereon, spreading upon the scale surface a liquid suspension of an oxide of magnesium, calcium, barium or strontium, evaporating off the liquid from the suspension and heating the steel to 1000-1230 DEG  C. in a reducing or neutral atmosphere to form a silicate coating thereon.  The scale produced by the first heating contains 25-40 per cent by weight of silica and 75-60 of iron and the second reducing atmosphere consists of coal gas which has only been partially combusted.  If the scale contains insufficient silica for the formation of the silicate, a mixture of finely divided magnesium oxide and silica in the form of a suspension is spread on the steel and the precess carried out as stated above.
