Title: Improvements relating to gas turbine engine combustion systems
IPC: F23R3/60
Filed: 1959-07-15
Abstract: 859,805. Generating combustion products under pressure. GENERAL MOTORS CORPORATION. July 15, 1959 [July 21, 1958], No. 24270/59. Class 51 (1). In gas turbine engine combustion equipment of the kind comprising a series of flame tubes disposed within an annular casing, each flame tube has at its upstream end a boss having an aperture to receive an actual or a dummy igniter plug, the plug and the boss having inter-engageable parts so arranged that the plug can be inserted through the aperture and may then be rotated to a position in which the parts can engage so that the flame tube can then be supported on the plug and the plug cannot be withdrawn. The object of the invention is to support the flame tubes temporarily pending the insertion of the fuel injector nozzles. The flame tube 22 is disposed within an annular casing, the outer wall of which is shown at 12, being normally supported at its upstream end by means of the fuel injector nozzle 42 engaging a central opening 38 in the flame tube end wall 28, and at its downstream end by means of the transition section 29 which engages within an annular sleeve 27 secured to the flame tube, the transition section being secured at its upstream end to the outer casing 20 by means of supports 31. A hollow boss member 50 is secured at the upstream end of the flame tube by means of a sheet metal plate 48, the radially inner end of the boss being formed with a transverse slot 54 which provides two ledge portions 55. The igniter plug 56 is provided with a flange 64 on its stem portion 62, the flange being of circular form with two side pieces cut away to provide a pair of parallel straight edges 66, the flange being so dimensioned that it may pass through the boss 50 when the edges 66 are disposed parallel to the sides of the slot 54. To support the flame tube therefore before the fuel injector nozzle 42 is fitted, the igniter plug 56 is entered through the opening 58 in the outer casing 12, through the aperture in the boss 50 and then through the opening 60 in the flame tube end wall 28, the plug being disposed so that the flats 66 on the flange 64 are parallel to the sides of the slot 54 in the boss 50 to permit this. The igniter plug is then turned through 90 degrees so that openings in the plug mounting plate 70 align with openings in the plate 76 fixed to the outer casing 12, the plug being secured in position by means of bolts 78. In this position the ledges 55 of the boss 50 rest on the curved end portions 68 of the flange 64 whereby the flame tube is temporarily supported on the igniter plug. Upon insertion of the injector nozzle 42, the flame tube will be displaced slightly so that the boss 50 is lifted off the flange 64, as shown in Fig. 1.

Abstract: 1317455 Automatic current and power regulation DANFOSS A S 21 May 1970 24644/70 Heading G3X [Also in Division H2] A circuit for supplying ignition control pulses to thyristors via which power is supplied to a load (1-3), Fig. 1 (not shown), comprises a condenser 15, a unijunction transistor 17 for discharging the condenser to provide an ignition control pulse when the voltage across the condenser reaches a predetermined value and a transistor 53 which is rendered conductive at the end of each half cycle of an A. C. supply to ensure that the condenser is discharged at the beginning of each half cycle of the alternating voltage. Each phase R, S, T of the A. C. supply is connected via a respective pair (7, 8, 9) of thyristors to the impendances (1, 2,3) of the load and three substanially similar circuits produce control pulses in the secondary windings of transformers 12-14 for triggering each pair of thyristors. Each circuit includes a transistor 16 which controls the thyristor firing angle by controlling the charging rate of the condenser 15. A variable resistor 38 of a potential divider 37, 38 connected across a Zener diode 48 is adjusted to set the charging rate. A variable resistor 25 of a potential divider 23-25 sets the voltage between the bases of the injunction transistor 17 and therefore determines the voltage at which the condenser 15 discharges by switching on the transistor, thereby providing the control pulse to the thyristor as the condenser discharges through the primary winding of the respective transformer 12-14. The condenser 15 charges and discharges more than once during each half cycle but as the A. C. supply approaches zero and the condenser is being charged, the transistor 53 is switched on to discharge the condenser. At the beginning of each half cycle of the A.C. supply the condenser 15 is therefore discharged. In the event of the supply voltage increasing, the voltage at the base of the transistor 16 increases so that the charging rate of the condenser 15 decreases, the thyristors are therefore fixed later in each half cycle to reduce the load current. The power dissipated in the load therefore remains constant.

Title: Improvements in auto copy paper and method of making the same
IPC: B41M5/124
Filed: 1959-07-20
Abstract: 889,629. Auto-copy paper &c. CORTEZ, J. C. July 20, 1959, No. 24795/59. Drawings to Specification. Class 96. [Also in Group XVI] An auto-copy sheet comprises a backing sheet and a continuous opaque coating containing a water-insoluble surface-active agent and pigment particles on one surface of said sheet, said coating being firm, dry and non-tacky and of a character such that the impact of a typewriter key under normal operation destroys the opacity of the pigment layer in the impacted area and reveals the surface of the underlying sheet in such area. The coating consists of printing ink to which has been added one or more of the following compounds: diethylene glycol monostearate, diethylene glycol monopalmitate, diethylene glycol monococate, pentaenythritol tetrastearate, glyceryl monostearate, glyceryl monomyristate, glyceryl monopalmitate, glyceryl monococate, ethylene glycol monomyristate, ethylene glycol monolaureate, polyethylene glycol stearate, polyoxyethylene lauryl ether, polyoxyethylene stearate, polyoxyethylene alkyl lauryl ether, polyoxyethylene lauryl ether. The compound is added in an amount equal to that of the pigment in the ink. In the case of water-based inks, the amount of film-forming adhesive therein is reduced. The volatile solvent may be omitted, thereby forming solid, thermo-fluid coatings, which are applied melted. The coatings are applied by roller coating-machines or printing-machines. In use, typewriter keys are impacted against the coating, or against a covering sheet. When pentacrythritol tetrastearate is used, the pigment adheres to the covering sheet, and if the latter is transparent, it can be used afterwards as an original for making photoprint copies. The base sheet and the coating are in contrasting colours, or either may be white or black, or the base may be transparent. The base colour may be produced by unmodified printing ink. In another form, areas of different colour coatings are applied to a white base, or a white coating to a base having areas of different colours, which are not wholly hidden by the coating.' Part of the area of the coating, or of each colour coating area, may be formed of unmodified ink so as not to reproduce characters. In another form, a transparent base sheet is provided with a coating of the modified ink, and a further coating of unmodified ink, to which rubber-like film-forming materials are added, e.g. Victoria blue ink base, synthetic rubber pliolite resin, chlorinated diphenyl, and toluol. The further coating may also be made transparent by omitting the Victoria blue base. A three-sheet leaflet comprises two ordinary sheets between which is an auto-copy sheet of darkcoloured paper, having on its top face a coating of white modified ink, the pigment not adhering to the top sheet, and on its bottom face a coating of the same colour as the sheet, the pigment of which adheres to the bottom sheet.
