IPC: D06P5/00
Filed: 1934-12-31
Abstract: Printing textile fabrics with dyestuffs requiring alkali for their fixation is effected with use, wholly or in part, as thickener for the printing paste of a vegetable mucilage, or a preparation obtained therefrom, which is not coagulable by alkali, and the dried prints are padded in a bath containing an alkali carbonate and a reducing agent other than a hydrosulphite, squeezed out, steamed moist and finished as usual.  Specified vegetable mucilages are those obtained from carob bean kernels or their husked de-germed and finely ground perisperms or from finely p  disintegrated salep tubers and the thickener may be obtained therefrom by boiling with water or by decomposition with acid or alkali with or without an addition of formaldehyde.  The following examples are given of the preparation of the thickener: (1) Ground carob bean kernel perisperms are stirred with water and boiled. (2) Ground carob bean kernel perisperms are boiled with water containing formic acid.  (3) Pulverized salep tubers are boiled with water containing formic acid.  (4) Ground carob bean kernel perisperms are heated to about 90 DEG  C. with water containing sulphuric acid and cooled while stirring.  The acid pastes obtained in (2), (3) or (4) may be neutralized with caustic soda and starch and water may be added and the mixture again boiled with water; alternatively, the starch may be admixed before the treatment with acid.  (5) Ground carob bean kernel perisperms are macerated for 2--3 days with water containing potash and/or with oils soluble or insoluble in water, and then boiled vigorously. (6) Ground carob bean kernel husks or perisperms are mixed with a caustic soda solution and then boiled vigorously with water and stirred until cold.  In an example of the use of the above thickness in printing, fabric is printed with an aqueous paste containing Indanthrene brilliant violet 2R and the thickener, dried, passed through a bath containing potash and sodium formaldehydesulphoxylate, and the moist fabric is then steamed for 5--7 minutes at 103 DEG  C., rinsed in cold water, soaped hot, again rinsed and dried.

IPC: H02H1/04
Filed: 1964-09-16
Abstract: 1,102,552. Protective systems. ENGLISH ELECTRIC CO. Ltd. 14 Sept., 1965 [16 Sept., 1964], No. 37916/64. Heading H2K. [Also in Division H3] In a protective relay responsive to an input signal and requiring a power supply, this supply is provided by a battery when a D.C. output derived from the signal is of insufficient magnitude, but when the output is sufficient it provides the power supply for the relay and charging current for the battery. The Figure illustrates a power supply circuit for a distance relay (not shown) and includes two input circuits 10 ... 13 and 16 ... 19 providing D.C. outputs dependent on the voltage and current respectively of a protected circuit. When the voltage is normal, a battery 30 is charged from the circuit 10.. .13 through a diode 25 and a Zener diode 22 breaks down so as to render transistors 27, 28 conductive and thus provide a D.C. supply to the relay measuring circuits (represented by a resistor 26). Similarly, when the current is sufficient, the output from the circuit 16 . . . 19 increases the voltage across a resistor 24 to cause the transistors 27, 28 to conduct and the battery to charge if the voltage on diode 25 is sufficient. A similar arrangement of diode 31, battery 36 and transistors 33, 34 provide a D.C. supply for supervisory circuits (represented by a resistor 32). A safety circuit which decreases the relay operating time when a power line having a fault near the relay point is switched in, may be provided. This safety circuit includes a transistor 40 which is rendered conductive by the initial charging current of a capacitor 39. A holding current for the transistor flows through a resistor 45 and diode 43 after a delay provided by the charging of a capacitor 44, this delay preventing incorrect operation due to spurious signals.

Abstract: 1,016,851. Non-reciprocal waveguide devices. RATHEON CO. Oct. 12, 1962 [Nov. 22, 1961], No. 38788/62. Heading H1W. A non-reciprocal differential phase-shifter comprises a non-circular waveguide having minor symmetry about two orthogonal axes, e.g. square or cruciform (as shown), and ferrite elements 46-49, arranged as shown, which produce zero differential phase-shift for one direction of propagation between orthogonally resolved wave components 44, 45 and 180 degrees differential phase shift for the other direction of propagation. When used as a circulator, each end of the guide is connected to a hybrid junction providing E and H-arm ports at either end. The junctions are orientated in such a manner that a wave applied to the input H-plane or E-plane port may be resolved into components 44, 45 having equal amplitude. Such a wave, after propagation through the phase-shifter, recombines to provide an output at either an E- or H-plane output junction. Since the phase shift is non-reciprocal, the device behaves as a 4-port circulator. One of the hybrid junctions may be replaced by an aerial, a transmitter and a receiver being connected to the remaining E- and H-plane ports. The device operates in the same manner as a conventional ferrite TR system.
