Abstract: 1,177,869. Anthraquinone dyes. CIBA Ltd. 9 May, 1968 [9 May, 1967; 7 July, 1967], No. 22054/68. Heading C4P. 1-Bromo-4-acylamino anthraquinones are produced by brominating 1-acylamino anthraquinones free from acetyl groups in the 2- position with bromine in the presence of water. The bromination may be carried out in a completely aqueous medium or in an aqueous organic solvent medium. An oxidizing agent and an acid may be present. The acyl group in the anthraquinone may be derived from a benzoic acid an alkanoic acid, a carbonic acid halfester, a heterocycliccarboxylic acid or an organic sulphonic acid.

Abstract: 375,597. Turbines; power generating systems. HOLZWARTH, H., 7, Goethestrasse, D³sseidorf, Germany. Aug. 14, 1931, No. 22987. [Classes 110 (iii) and 122 (iii).] A power plant of steam engines or turbines is provided with a gas turbine plant for periods of peak loads on the electrical supply system, the waste heat of the gas turbine plant being used to increase the steam generated by the boilers of the main plant. Steam engines or turbines 1 are supplied with steam from a battery of boilers 7 through a line 8. Condensate pumps 2 and the boiler' feed pump 3 supply economizers 4 and a collecting manifold 5, which is connected to a second manifold 6 by a valve 17. A condensate collecting tank 16 is provided. An explosion turbine 9 and a second stage gas turbine 10 drive an electric generator 12 and a compresser 11. Prior to the peak load, valve 17 is closed and valves 18, 19 opened and hot water from the economizers 4 flows through a heat-exchange apparatus 13, heated by the exhaust gases from the turbine 10, to the cooling jacket of the turbine 9, and passes by way of a pipe 15 to the manifold 6. A pump 20 may be provided if the pressure in the jacket of turbine 9 is less than the pressure in the manifold 6. Turbines 9, 10 need not be coupled together. Steam may be generated by the waste heat of the exhaust gases, in a generator (not shown), and led to a collector 22, the line 15 being dispensed with. In a further arrangement part, or all, of the exhaust gases may be led to the furnace grates of boilers 7, or used to preheat the feedwater to the boilers. In another modification water from the economizers may flow continually through the jackets of turbines 9, 10 to keep these warm and ready for starting up. The heat from the waste exhaust gases may also be used to superheat the steam. The economizers 4 may be replaced by feedwater heaters heated by steam bled from the turbines.

Tongs for supporting glass, particularly during annealing, are suspended from a carriage by means permitting a measure of vertical movement in such a way that the tongs hang freely and capable of pivoting movement in their lowermost position but when lifted are held rigid with the carriage by complementary interengaging members. In the form shown, Fig. 1, a carriage 12 which runs on rollers 10 on shafts 11 and supports, through a link 14, the member 16 to which the tongs are attached. The tongs are also shown in section in Fig. 2. The member 16 carries a frame member 20 with an upstanding conical pivot 28 engaging a seating 34 in a member 30 to which a clevis 40 is attached by plates 36, 38. Links 46, 48 are pivoted to-the pin 42 in the clevis 40 and to the tong arms 54, 56 pivoted together at 58. Pointed screws 64, 66 are threaded into the arms and grip the edge of the glass G. The upward movement of the glass, as it is lifted into position, is limited by a member 70 on the pivot 58. As the edge of the glass engages the member 70 the whole tong assembly is lifted off the pivot 28. The member 30 has an upper surface 32 of angular shape complementary to the shape of the lower surface 24 of a member 18 at the top of the frame member 20. The engagement of these surfaces aligns the tongs accurately vertical and perpendicular to the direction of travel of the carriage 12. The member 70, and alternative devices for the same purpose form the subject-matter of Specification 908,389.

Title: Improvements in circuits for colour television
Inventor: SILVIE WILLIAM
IPC: H04N11/14
Filed: 1956-07-26
Abstract: 806,391. Colour television. BRITISH BROADCASTING CORPORATION. June 3, 1957 [July 26, 1956], No. 23193/56. Class 40 (3). Relates to a colour television system utilizing a luminance signal and a chrominance signal which is located within the band of the luminance signal and is in the form of two sub-carriers of the same frequency but having a quadrature phase relationship. At a receiver, when the chrominance signal is detected by means of two synchronous detectors to derive the colour information, components of the luminance signal located at or near the subcarrier are also detected and may prove troublesome in the picture display. In accordance with the invention, this defect is eliminated at the transmitter by suppressing or attenuating the band of luminance frequencies around the sub-carrier frequency. To do this the luminance signal at 10 is applied in parallel to two synchronous detectors 11 and 12, oscillations at sub-carrier frequency being supplied from terminal 13, the connection to detector 11 including a 90 degrees phase-shifter. The detector outputs are derived through lowpass filters 15 and 16 and applied to balanced modulators 17 and 18, which are fed with subcarrier oscillations obtained respectively from phase-shifter 14 and terminal 13. The outputs of the modulators are then added in adding circuit 19 and finally subtracted from the original luminance signal in circuit 20. In effect the components around the sub-carrier frequency it is desired to suppress are shifted to the bottom of the spectrum by detectors 11 and 12, so that they may be selected by low-pass filters 15 and 16, and then restored to their original frequencies by modulators 17 and 18 before subtraction. The arrangement avoids the use of a band-pass filter, which in the particular circumstances is difficult to design. Delay networks 21 and 22 are designed to introduce a delay equal to that produced by filters 15 and 16. Delay network 23 introduces a delay equal to that encountered by the luminance signal in passing through the system from terminal 10 to subtracting circuit 20.
