Patent GB-808262-A (GB)
Title: Ice-colours in textile printing and dyeing
Filed: 1957-07-02
Abstract: Ice-colours in textile printing or dyeing are obtained by applying a composition containing a coupling component and a diazoamino compound derived from a diazotized weakly negatively substituted amine of the benzene series and 2-carboxy-5-nitrophenylamino acetic acid, and then developing the dyestuff by steaming with neutral steam.  Suitable weakly negatively substituted amines are halogeno-, halogen-alkyl- or alkoxy-anilines, dihalogenoanilines or -toluidines, trifluoromethyl anilines, dianisidines and amino-benzene sulphonamides.  The composition may be printed side-by-side with vat colours.  Examples describe the printing of cotton and regenerated cellulose staple fibre fabrics.  Specifications 715,249, 743,308 and 745,128, [Group IV (b)], are referred to.

Title: Method and apparatus for sorting materials
IPC: B07C5/36
Filed: 1958-07-01
Abstract: 855,678. Controlling sorting by radiation. K. & H. EQUIPMENT Ltd. July 1, 1958 [Feb. 28, 1958], No. 20983/58. Class 40(3). [Also in Group XXIX] Rock pieces having a physical property which . can be translated into electrical energy are sorted from a mass of pieces by allowing the pieces to fall in a substantially single row, detecting from the falling pieces those having the physical property and deflecting the others by air blasts. As shown, falling rock pieces from a conveyer 1 pass a detector 14, then interrupt a photo-cell beam, and then pass a valve controlled nozzle 17. A circuit 23 including an electronic relay 24 connects the photo-cell 15 and the valve 20 (see Group XXIX) to operate the air blast when the photo-cell beam is interrupted, but this circuit is broken through an electronic device 22 to inhibit the air blast when the detector identifies pieces having the physical property. Thus pieces having the physical property fall undeflected whereas those not having it are deflected by air blasts. The detector may be a lead-shielded scintillator for radio-active ore, a photo-cell sensitive to a particular colour, a photo-cell sensitive to fluorescent light for rock containing minerals which fluoresce when exposed to a certain wavelength of ultraviolet light, or a photo-cell sensitive to X-rays for materials having varying penetration powers towards X-rays. Alternatively, the detector may be a coil of wire which will detect rock containing minerals having magnetic properties as it falls through or near the coil.

Filed: 1919-08-30
Abstract: 152,176. Heyen, A. P. Aug. 30, 1919. Combined electric and combustion-heated furnaces.-A mixture of air and heavy hydrocarbons is passed into an electric steel furnace through hollow electrodes so as to diminish the resistance of the arc. In the furnace shown, heavy oil is fed through pipes 8, mixes with air entering through perforations from surrounding chambers 11, and passes down through hollow electrodes 6 into the furnace. Funnels may be provided at the upper ends of the pipes 8. The gaseous products escape by flues 4 and by narrow spaces in the roof around the electrodes; or the flues 4 may be closed by cemented doors. Initially, the furnace is heated by coke, and may then 'be charged with steel turnings, a little coke being placed under each electrode. As soon as the arcs are steady, the mixture of fuel and air is introduced, and the arcs can then be lengthened. Excess of air is first admitted, and subsequently the impurities are removed, lime and fluorspar are added, and the air is reduced below the amount required for combustion, so that deoxidation and de-sulphurization take place. The furnace walls and roof are protected by the gas.

A rotary hydraulic pump, or motor, comprises a plurality of pistons 12 lodged in an annular chamber 11 within an eccentric rotatable housing 9 that is situated between two non-rotatable plates 21 and connected to a driving, or power-output, shaft 2 by a positive coupling 10, each of the pistons being coupled to a radial arm 13 by a part-spherical bearing-bush 14 so that it is free to move radially and rock relative to the arm, which is fixed to a hub or collar 16 on said shaft by a pin 15. In operation, rotation of the shaft 2 effects rotation of the housing 9 and the pistons in the same direction while the pistons oscillate relative to each other so that working fluid is pumped from an inlet port 19 in one of the plates 21 to an outlet port 20 in the same plate by way of arcuate ports 18 in the housing 9, the latter said ports being in register with working spaces between the pistons. The shaft 2 is supported by a pair of bearings 3 whereas the housing 9 has hollow trunnions 8 supported by bearings 7 lodged in a casing 4 that is movable radially so as to vary the eccentricity of the housing relative to the said shaft and hence the output of the pump or motor, the casing coupled to a hydraulic jack 5 that is mounted on an outer casing 1. Rotation of the housing 9 in the same direction as the pistons reduces friction and wear.

Title: Improvements in or relating to television receivers

Abstract: 672,648. Television. MULLARD RADIO VALVE CO., Ltd., and JONES, E. Aug. 16, 1948, No. 21568/48. Class 40 (iii). [Also in Group XL (c)] A circuit modifies the waveform of a frame synchronizing pulse derived by a process of integration before it is applied to the discharge device of the scanning generator to ensure that a maximum potential occurs shortly after the commencement of the pulse and thereafter interfering signals are wholly or in part removed from the pulse. The frame synchronizing pulse appears as shown in the upper full curve of Fig. 4 and is applied to terminals 5, 6 of the circuit shown in Fig. 3. The time-constant of network C1, R1 is chosen in relation to the rate of rise of the pulse so that the maximum amplitude of the potential at the anode A of diode D occurs shortly after the commencement of the pulse, and the time-constant of network C2, R2 is made greater than that of network C1, R1 with R2 greater than R1. By this means the diode conducts whilst the potential at A is rising and thereafter remains non- conducting. The potential on the anode is as shown in the lower full curve of Fig. 4, and the output potential at terminals 7 and 8, which is applied to the scanning generator, as shown in the dotted curve. The diode remains non- conducting over the greater portion of the frame pulse and interfering signals such as X and Y are eliminated from the output. Preferably a bias potential is applied in series with either R1 or R2 to render the diode non-conducting in the interval between frame pulses so that interfering signals occurring in this interval are also eliminated. A copper-oxide rectifier, or silicon or germanium crystal may replace the diode. The diode connections are reversed when the input synchronizing, pulses are negative.
