Patent GB-901215-A (GB)
Title: Improvements in or relating to a fail safe electrical circuit
Inventor: BRANCH MAURICE CHARLES
IPC: B61L1/20
Filed: 1960-02-25
Abstract: 901,215. Circuits for bi-stable magnetic cores. STANDARD TELEPHONES & CABLES Ltd. Feb. 24, 1961 [Feb. 25, 1960], No. 6589/60. Class 40 (9). A fail-safe circuit comprises a core A having input windings wal . .. wa3, a shift winding wa4, a bias winding wa6 and an output winding wa5 connected in a common-emitter transistor circuit T1 via a resistance R 1  to the input winding wb1 of a second core B having an output winding wb2 and a shift winding wb3 connected in series with the bias winding wa6. Core A operates as an AND circuit for pulses on wal ... wa3 which are applied simultaneously with an opposing bias pulse (see Fig. 2), all three cores having to be pulsed to overcome the bias and set the core. The immediately following shift pulse A resets the core to cause transistor T1 to conduct, thereby setting core B. The next shift B pulse resets core B to produce an output from wb2 via transistor T2 to the next stage. If two or less of the cores wa1 . wa3 are pulsed then, since the hysteresis loop is not perfectly rectangular a short duration " sneak " pulse may be produced when wa4 is energized, thereby partially setting core B. In the succeeding stage this will be fed to core A during the early part of the shift B/bias pulse, but, as seen from Fig. 2, the shift A pulse is still present at this time and prevents the sneak pulse from effecting the core A. The design of the circuit ensures that in the event of any winding being open or short-circuited or any of the supplies failing or any of the cores or the transistor failing no output pulse is provided.

Title: Improvements relating to gas-turbine engine fuel systems
Inventor: BALLANTYNE DAVID HAVELOCK
IPC: F02C7/22
Filed: 1949-03-10
Abstract: 667,022. Gas turbine plant; centrifugal pumps. ROLLS-ROYCE, Ltd. March 1, 1950. [March 10, 1949] No. 6600/49. Classes 110(i) and 110(iii). A gas turbine power plant installationhaving a fuel supply tank remote from the engine or engines and main or auxiliary fuel supply systems has a fuel pump located adjacent to or incorporated in the fuel supply tank driven by an air motor, such as a turbine, which motor is supplied with compressed air from the compressor system of a gas turbine engine. The fuel to a gas turbine engine, Fig. 2, is supplied by an engine driven pump 24 supplied in turn by a booster pump 19 driven by an air turbine 21 which receives air from the compressor 11 system of the gas turbine engine. An electrically driven pump 19a is provided for starting purposes. In a modification, the pump 19 is used to boost a second engine driven pump supplying fuel-to reheat burners in the turbine exhaust pipe. In another modification, Fig. 4, two air turbine driven pumps 30, 31 are provided. The pump 30 is used to boost the engine driven pump 24 supplying fuel to the main burners 16 and the pump 31 supplying fuel to the reheat burners 25. Arrangements are made to connect the valve 38 controlling the air supply to the turbine 35 with the valve 37 in the discharge of the pump 31. The pump 30 may rotate at a slower speed than that of the pump 31. In a further modification, two pumps are arranged hydraulically in series to supply fuel to the reheat burners 25. These pumps are driven by a common turbine, the low pressure pump being driven through gearing at a lower speed than the high pressure pump. An air turbine driven pump, Fig. 6, comprises a plate 51 made integral with the lower half 63a of the centrifugal pump casing and the upper O1 exhaust half 52 of the turbine casing. A turbine nozzle plate 59 is clamped between the two halves of the casing 52, 58. A legging 66 prevents leakage of fuel along the shaft 54. The plate 51 is bolted to the fuel tank 50 so that the centrifugal pump is submerged. To avoid icing of the turbine due to the expansion of the air, the operating air may be taken from the space between the flame tube and outer air casing of each combustion chamber. The air motor may be of the piston or vane type and the pumps of the gear or reciprocating type. The term "fuel" is stated to include additional liquids such as a watermethanol mixture which may be injected into the compressor. Specification 608,963 is referred to.

In a travelling-cylinder type printing machine in which a cylindrical rotatable platen 25 of the dry or ink type is hand rolled over superimposed copy sheet material and relief printing plates the document to be printed and the plates 32 and 38, as well as a dating device 41, are mounted on a tray 30 which is readily insertable in or removable from the base 13 of the machine carrying the platen. The tray carries a rubbertipped clip device 44 for holding the document at one edge and guide members 33 and pin members 34 for locating the printing plate 32, which is holed along one edge to accommodate the pins 34, in correct position relative to the platen when the tray is fully inserted into the machine base 13. The plate 38 is held in position by guide flanges 37 upstanding from the tray. The latter is indented with recesses 48 beneath the positions of the plates 32 and 38 to assist ready removal of the latter. Marks X on tray and base are provided to ensure accurate alignment and the platen 25 is rockable about its housing to allow lifting from the document on the return, i.e. non-printing, stroke. It will be appreciated, however, that one could readily modify the present invention allowing bidirectional imprinting to be possible by either merely fastening the right-hand side of document 45 or providing a rigid platen head assembly with limited movement over the document.

The cage is movable along the guides under the control of a hoist 23 mounted on separate structure above the furnace and having hoist cables 24 supporting a sheave block 25 removably attached to the cage. An overspeed hoist stop governor 69 is mounted at the top of the cage guides and is associated with an endless rope 72 secured to the cage. The elevator is formed in three detachable sections, bolted together during assembly, the upper section comprising an upper tower portion, upper cage guide portions and the cage, the bottom of the cage having feet 59 engageable with abutments at the top of the tower so that hoisting of the cage during erection also hoists the tower and associated guides. The elevator middle section comprises a lower tower portion and middle cage guide portions and the elevator bottom section comprises lower cage guide portions mounted on a base 49. Each of the elevator sections is delivered in position beneath the furnace on a mobile trailer 18, each section being delivered once the preceding section has been lifted.

[Classes 145 (i) and .145 (ii)] Articles such as small boats are made from a number of plywood or similar wooden sheets 4 cemented together by a glue in the nature of a synthetic resin, the sheets being pressed over a rigid core 1 mounted on a table 2 by means of membrane 5 which is pressed by fluid pressure, e.g. atmospheric pressure due to exhaust of air through a pipe 7 which passes through the table 2. The characteristic feature of the invention consists in making the table fluid-tight by a metal lining or film 3 on the underside of the table having margins 3a which are bent up and laid flat on the top side of the table, the membrane 5 being pressed against the margins 3a. The membrane 5 may be positioned by unwinding it from a roll 8, Fig. 2, on a shaft fitted with gear wheels 9 which move on tracks 10 mounted in a frame 11. The membrane 5 is secured to,the table by clamps 6, and in a modification, Fig. 3 (not shown), a thin wrapper may hold the sheets to the core, the wrapper being held at its edges in clamps over which the membrane 5 is placed. The sheets 5 may be formed of sections having overlapped bevelled edges, and heating may be effected by passage of electrical currents through a metal sheet 13, e.g. of lead, which covers the core 1. A current of low voltage and high intensity is preferred.
