Title: Improved process for dyeing nylon textile materials
Inventor: HADFIELD HARRY ROSE
IPC: D06P3/28
Filed: 1951-08-01
Abstract: In the formation of azo dyestuffs on nylon textile materials, an arylamide of a hydroxy-carboxylic acid (coupling agent) and a diazotized arylamine which has been combined with a primary or secondary amine are applied simultaneously from an aqueous bath and the azo dyestuff subsequently developed by treatment with a hot aqueous solution of a mineral acid.  Arylamides of 2 : 3 hydroxynaphthoic acid, o-hydroxycarbazole carboxylic acid or acetoacetic acid may be employed, in the form of the free hydroxy compound, in neutral or slightly alkaline dispersion or as the sodium salt in strongly alkaline solution.  In an example, an aqueous paste of the 5-methoxy-o-toluidide of 2 : 3 hydroxynaphthoic acid containing Turkey Red Oil is heated to the boil and caustic soda is added.  The clear solution so obtained is poured into an aqueous solution of sodium chloride to which an aqueous dispersion of the triazene obtained from diazotized 5-chloro-o-toluidine and diethanolamine is added and the mixture heated to 80 DEG C.  Nylon yarn is immersed in the mixture, then washed, immersed in aqueous hydrochloric acid at 70 DEG C., soaped, rinsed and dried. Specifications 464,511 and 539,195 are referred to.

Title: Improvements in and relating to superchargers for internal combustion engines
IPC: F02B37/22
Filed: 1926-07-23
Abstract: 255,894. British Thomson-Houston Co., Ltd., (Assignees of Moss, S. A.). July 27, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Motor power plant; regulating. - T h e speed of a supercharging pump of an internal - combustion engine is regulated by varying the area of the passage of exhaust gas through a turbine driving the pump. The pump shaft 10 is driven by a turbine comprising a rotor 12 having a ring of buckets 13 which are supplied with exhaust gas through a pipe 22 and nozzles 25, the exhaust leaving by a pipe 23. The nozzles extend over an are of the turbine rotor and are supplied through a box 24, Fig. 2, which may be divided into three parts a, b, c by valves 26, 27. These valves are rotated through racks 29 and pinions by cams 35, 36 on a shaft 34. Also mounted on this shaft is a cam 44 which opens a valve 42 regulating the combustible mixture leaving the pump. The cams are arranged so that, when the shaft is rotated by depressing an accelerator pedal 41, the valve 42 is first opened and then the valves 26, 27 are successively closed, and by this means the spead of the pump is gradually increased. If the turbine is of the reaction type, exhaust gas is admitted to the inside of a ring of buckets and leaves them in a radial direction where an annular valve regulates the flow; this valve is moved by the cam shaft 34 and replaces the valves 26, 27.

Title: Improvements in or relating to shaft seals
IPC: F04D29/10
Filed: 1956-06-14
Abstract: 794,470. Stuffing-box substitutes. SCHELLENS, C. A. June 14, 1956 [Aug. 9, 1955], No. 18497/56. Class 122 (5). A seal for a rotary or reciprocating shaft 14, Fig. 1, where it protrudes from a casing 10 containing liquid under pressure comprises a series of axially-spaced seals 22, 24, 26 which are arranged in a stuffing-box 12 with leakage-liquid receiving spaces 34, 36 between successive seals, a passage 60 leading from an inlet 61 communicating with the casing 10 to an outlet 46, branches leading from the passage 60 to the spaces 34, 36, and restricted openings spaced along the passage for the purpose of regulating the flow of liquid through the latter and maintaining a substantially uniform drop in pressure from the casing to the first leakage space and from such space to the next and so on. The seals are of equal length and each is allowed sufficient leakage to keep it moist. The passage 60 leads to atmosphere at 46 from an annular groove 61 in the neck 16 of the casing 10 and is built up of branches 50, 52, 54 communicating, respectively, with the annular groove 61 and spaces 34, 36 which are constituted by lantern rings 28, 30 between the seals; perforations 32 in the rings 28 communicate with the spaces 34, 36. Orifices 64, 66, 68 provide restricted communication between the branches. The radial clearance between the neck portion 16 and the shaft is less than the diameter of the orifices and is small enough to prevent particles in the casing from reaching the first orifice. A gland 38 at the outer end of the stuffing-box 12 is adjusted to permit a slight leak along the shaft through the packings to prevent them from overheating, but liquid from the branches 50, 52, 54 ensures adequate moistening of the packings without excessive leakage through the gland 38. The pressure drop across each packing group is equal to the total pressure to be sealed divided by the number of groups of packing, so that the unit rubbing pressure against the shaft is reduced proportionately. In the modification shown in Fig. 3, conical packing rings 82, 84, 86 of the self-sealing type are used; and the stuffing-box comprises bolted sections 74, 76, 78, 80 fitting closely on the shaft to form with passages 88, 90 a duct containing orifices 92, 92<SP>1</SP> through which liquid flows with the same pressure dropping arrangement as described with reference to Fig. 1. Carbon rings may be used in place of soft packings, and the shaft may be provided with a wear sleeve 15.

Title: Improvements in or relating to telegraph signal converters
IPC: H01G9/022
Filed: 1966-04-29
Abstract: 1,104,212. Transistor switching circuits. SIEMENS A.G. 29 April, 1966 [30 April, 1965], No. 18807/66. Heading H3T. In a telegraph converter for converting single current signals into double current signals, two similar transistors Ts2, Ts3, which are connected in series between supply terminal -TB, +TB, are rendered conductive alternately by signals of opposite polarity supplied to them from a driver transistor Tsl which is fed with the single current signals. As shown the output transistors Ts2, Ts3 conduct alternately to connect either the positive or negative pole of the telegraph battery to the output terminal a. The windings I and II of a transformer U are connected so as to ensure that the appropriate transistor Ts2 or Ts3 rapidly turns off when the other one is caused to conduct, so as to reduce the effect of the stored charge carriers. The diode bridge Gr1 and Zener diode ZD2 arrangement in the output of the circuit limits the open circuit voltage of the output and prevents the collector voltage of the non-conducting transistor rising beyond an allowed value if a high external voltage is accidentally applied to the output. Further protection against an excessive voltage being applied to the output or against the output being short circuited is provided by a lamp SL or protective cut out which may replace the lamp.
