Patent GB-784394-A (GB)
Title: A new or improved method of dyeing textile material
Inventor: LUCZYNSKI WLADYSLAW FILIP
IPC: D06P3/34
Filed: 1953-06-12
Abstract: Textile materials are dyed by impregnating with an aqueous vehicle containing one or more dyestuffs suitable for dyeing the fibres, which dyestuffs are not adversely affected by a temperature of 160 DEG  C. and above, and then subjecting the impregnated material to a heat treatment in hot air at a temperature above 160 DEG  C. and below 235 DEG  C. for a period sufficient both to dry the material and fix the colour, the hot air containing no added water vapour other than that liberated from the material.  The heat treatment may be effected by passing the material through a hot air chamber or chambers, preferably having zones of decreasing humidity, or through a hot air stenter. In the case of heat-setting fibres such as those of polyamides or polyesters, the heat treatment may be effected with the material under tension to set the fibre during dyeing.  The aqueous dye liquor preferably contains ammonium thiocyanate.  For dyeing cellulosic fibres the liquor preferably contains a strong electrolyte such as sodium chloride, and for dyeing polyacrylonitrile fibres glycerine may be added to the liquor. Polyester fibres may be dyed with leuco sulphuric acid esters of vat dyes, dispersed acetate and water-soluble acetate dyes.  The process is applicable to the dyeing of union fabrics, and in the case of polyamide-polyester unions a solid dyeing may be obtained, or dyeing of the polyester fibres with reservation of the polyamide fibres may be effected, and such a union may be subsequently bleached to remove the colour from the polyamide fibres and, if desired, then cross-dyed.  The dyeing of polyester and polyacrylonitrile fibres and fibre-blends of polyester-wool-viscose rayon, polyester-cotton, polyester-polyamide, polyester-cellulose acetate and animal fibre-regenerated protein fibre is described.

Filed: 1939-12-22
Abstract: 539,773. Electromagnetic relays. MULLER, H. Dec. 22, 1939, No. 16258/38. [A Specification was laid open to inspection under Sect 91 of the Acts, Dec. 1, 1938.] [Class 38 (v)] [Also in Groups XXXV and XXXVI] The permeability of a magnetic conductor carrying a main flux N is controlled by current in a saturating winding R1 arranged on a fixed magnetic member R lying transverse to the direction of the main flux and remote from any winding used in producing the main flux. The arrangement may be applied to an electromagnetic relay, the variably saturated part of the magnetic circuit forming a magnetic shunt to a permanent or electromagnet which cooperates with either a moving coil or an armature carrying contacts. Specification 171,218, [Class 38 (ii)], is referred to.
Patent GB-914751-A (GB)
Title: Improved device for the measurement of magnetic field by magnetic resonance
IPC: G01R33/24
Filed: 1959-05-12
Abstract: 914,751. Magnetic testing apparatus. COMMISSARIAT A L'ENERGIE ATOMIQUE. May 12, 1959 [May 17, 1958], No. 16301/59. Addition to 888,439. Class 37. [Also in Group XL(c)] In a magnetometer of the type described in the parent Specification, particularly for measuring the earth's field, a solution of a specified range of paramagnetic substances is excited at the frequency of an electron resonance band of the substance and energy is emitted by the stimulated nuclear resonance of the solvent at a frequency proportional to the strength of the unknown field. The energy is received by a tuned circuit having a high Q factor, magnetically coupled to but electrostatically screened from the solution. In the apparatus described an aqueous solution of nitrodisulphonate ions contained in a methylmethacrylate vessel 52 is surrounded by two coaxial coils 53, 54 located at right-angles to the unknown field. An electrostatic screen 55 of silver or copper is provided. Coil 53 is fed from a generator 60 operating at 55 Mc/s., the electron resonance frequency of the solution. Fig. 2 (not shown) gives a circuit diagram of a suitable electron-coupled oscillator and buffer amplifier. Fig. 3 shows the coil 54 tuned by capacitor 57 to the nuclear resonance frequency (2.1 kc/s.) of the solution. The tuned circuit is coupled to an oscillating detector 61 comprising valves 101, 102 having positive feed-back via resistor 108. The Q factor of the circuit must be sufficiently high for the energy emitted by the solution at the nuclear resonance frequency to maintain oscillation. The output of the oscillating detector 61 is fed to an amplifier 64 which is tuned to pass 2.1 kc/s. by feed-back via the twin T filter 126. Positive feed-back between the cathodes of valves 123, 119 improves selectivity. The diode 127 and meter 128 form a peak valve voltmeter. The nuclear resonance frequency and hence the strength of the earth's field is determined by a counter connected to terminal 65 and operated over approximately 100, 1000 or 10,000 cycles depending on the required accuracy. The circuit should be tuned to the nuclear resonance frequency preferably by automatic control of capacitor 57 or of the bias current of a ferritecored inductor which may be connected to coil 54. A list of appropriate paramagnetic substances and solvents is included.

Title: Improvements in and connected with means for damping vibrations between electric contacts
IPC: H01H3/60
Filed: 1938-06-01
Abstract: 514,578. Oil-break switches. CRABTREE CO., Ltd., J. A. (Schiele Industriewerk). June 1, 1938, No. 16327. [Class 38 (v)] To damp down any vibrations between the contacts of an electromagnetic switch at "make," the moving contact 5 carries a disc 8b which moves close to the walls of an oil container 1. The disc 8b may be perforated as shown and associated with another disc 10 which acts to close the perforations when the contact assembly moves upwards under the action of the electromagnet 3 to bridge fixed contacts 6a, 6b; but moves away from the perforations to allow oil to flow through them during the switch opening movement. There is thus a quick "break " and the flow of oil helps to quench any arc.
Patent GB-1041886-A (GB)
Title: Signal transmitting system
IPC: H04Q9/00
Filed: 1964-04-20
Abstract: 1,041,886. Counters; electric selective signalling. JOHNSON SERVICE CO. April 20, 1964 [Dec. 26, 1933], No. 16358/64. Headings G4A and G4H. [Also in Division G1] In a system for transmission of data between the transmitters and receivers of a number of pairs of stations the stations are arranged in groups and a group of transmission lines is employed in time or frequency multiplex manner to transmit data simultaneously from one station in each group to the corresponding receivers. An embodiment comprising 64 pairs of stations, e.g. thermostat switches 40 and relays 41, has the stations arranged in groups of eight. By pulsing each line of the supply group 42 in sequence by way of counter 43 the settings of eight switches in one row are transferred to the corresponding relays at 41. Diodes 46, 48 prevent current flowing in other than the correct paths. The counter comprises eight sections 53-60, the first differing somewhat from the others. Winding 65 is one secondary of transformer 61. When a positive half-cycle occurs S.C.R. 66 fires, developing a pulse in transformer 67 which energizes the gate electrode of the second stage. The winding 65 of this stage being inverse to that of the first stage the succeeding negative half-cycle fires the S.C.R. of the second stage, and so on. The eighth stage triggers the first stage. After the first positive pulse relay 71 is energized by the output pulse of the first stage and remains energized by capacitor 79 for a full cycle so that subsequent positive cycles do not fire S.C.R. 66. In the event that there is no load between the output terminals of one stage, e.g. if the switches 40 which it feeds are open, no triggering pulse would be fed to the next stage were it not for the parallel connection 74, 75. To prevent faulty operation of the unit if a spurious triggering pulse occurs, if the first stage pulses more than once during the time in which the unit makes one cycle, i.e. a count of eight, capacitor 90 charges sufficiently to energize relay 64. This breaks the main supply of A.C., and when both capacitors 90 and 79 have discharged the supply is reconnected and the first stage pulses as described above. Other embodiments describe systems in which a voltage source is applied sequentially to the lines of the supply group by a rotary switch; or in which a separate voltage source is associated with each supply line, the circuits being closed sequentially; or in which the supply lines are fed simultaneously by alternating sources of distinctive frequency. An arrangement in which the transmitters send an analogue value indicating temperature is described (see Heading G1N).

This wheel operates a rack 37, the movement of which is transmitted by a bell-crank 38 to a gear wheel 39 mounted similarly to the wheel 21 and engaged by a cylinder 42 similar to the cylinder 22, the cylinder 42 being driven by the wheel 21 through the long pinion 23. The rotation of the wheel 39 is then dependent on the product of the water flow and the temperature difference and is transmitted by gearing 40, 41 to a counter &c. 5. Indicators may be actuated by the wheels 18, 36.

Abstract: 530,167. Measuring specific gravity of liquids. NAAMLOOZE VENNOOTSCHAP DOMANIAL MIJN MAATSCHAPPIJ, and TROMP, K. F. June 5,1939, No. 16478. [Class 97 (iii)] Liquids having solids in suspension, for example water and sand, are fed by a pipe 15 into a fixed tank 14 having an overflow pipe 16 and a discharge pipe 17 depending to the middle of a vat 6 suspended from the beam 4 of weighing apparatus, the vat having an outlet 9 at the bottom and also an outlet 11 discharging through a spout 12 at the top into a fixed outer casing 13 with bottom outlet 13a. The end of pipe 17 is preferably fitted with a transverse baffle 18 to direct the liquid horizontally into the vat. The liquid may be maintained at constant specific gravity by supplying light and heavy mixtures respectively through pipes 24, 24a, Fig. 1, into divided chambers 21, 22 and 21a, 22a fixed to the tank 14, the compartments 21, 21a discharging into the tank 14 and the others into a pipe 23. The proportions flowing to the tank are determined by baffles 25, 25a opposite the inlet pipes and suspended from the balance beam so as to move with the vat. In the arrangement shown in Fig. 3 heavy liquid is supplied directly to the tank 14 by pipe 15, and water supplied by pipe 29 is diverted by a baffle 32 carried by the balance beam into the tank or to a waste pipe 27. The spout 72 of the upper outlet of the vat 6 discharges into a pipe 33 for use of the liquid when it is correct. When the liquid is incorrect the spout 12 discharges into the casing 13. The movement of the balance may be employed to actuate relays controlling liquid supply valves to maintain the specific gravity constant. The apparatus may be used in conjunction with the apparatus set forth in Specification 466,964, [Group II], for separating materials of different specific gravity.
