Title: Engine fuel system
Inventor: JOHNSON CHRISTOPHER LINDLEY
IPC: F02C7/224
Filed: 1958-11-19
Abstract: 865,481. Supplying oil to burners. ROLLSROYCE Ltd. Nov. 12, 1959 [Nov. 19, 1958], No. 37305/58. Class 75(1). [Also in Group XXVI] In an engine fuel system, the fuel passes from a reservoir through a fuel to fuel heat exchanger, through a fuel line including a fuel control unit and heating equipment means and then through the heat exchanger again to the burners, so that the fuel heated in the heating equipment means serves to heat in the heat exchanger the fuel flowing from the reservoir. The heating equipment means may be a heat exchanger such as an oil cooler or may be or may include a pump. A gas turbine engine fuel system comprises a fuel tank 1 from which fuel is supplied by a booster pump along a conduit 2, through a fuel to fuel heat exchanger 7, an oil cooler 8 and an air heated heat exchanger 9, filter 9a, fuel flowmeter 10 and a high pressure pump 11 to a fuel control unit 3. Heat is added to the fuel in the oil cooler 8, heat exchanger 9 and to some extent in the pump 11. The fuel flowing through the conduit 4 to the burners 5 gives up heat in the exchanger 7 to the fuel in the conduit 2. A by-pass conduit 12 controlled by a valve 13 prevents the fuel temperature from becoming excessive. The valve 13 may be controlled manually or automatically in accordance with the fuel temperature at some point in its flow. In a modification, Fig. 2 (not shown), the oil cooler 8 is arranged on the discharge side of the pump 11 and the by-pass pipe is arranged on the low pressure side of the heat exchanger. The flows of fuel are preferably contra-flow to one another. In another modification, Fig. 4 (not shown), the oil cooler 8 is arranged in two parts through which the fuel flows in parallel and the oil in series. In a further modification, Fig. 5 (not shown), in which both pilot and main burners are provided the fuel flows to both sets of burners are arranged in contraflow to the flow of fuel in conduit 2. The conduit leading to the pilot burners extends adjacent a minor proportion, i.e. downstream portion only of that part of the conduit 2 in the heat exchanger 7 so that the fuel supply to the pilot burners loses less heat than the fuel supply to the main burners. An arrangement in which the valve 14 is automatically operated simultaneously with a valve in the conduit 4 is also described. These valves may be actuated by a thermostat in response to the fuel temperature in the supply line so that they are either opened or closed. A warning light is provided to warn the pilot of the fuel temperature conditions. In a further modification, Fig. 7 (not shown), the effective size of the heat exchanger 7 is reduced by making it in the form of two cylinders. The oil cooler 8 may be in the form of two cylinders.

The mandrel may be a single permanent magnet, or may have permanent magnets 22, 22 1 , 22 2 , 22 3 , 26, 261, 26 2 , 26 3 , Fig. 5, embedded in it beneath the parts where the ferromagnetic elements 23, 23 1 , 23 2 , 23 3 , 27, 27 1 , 27 2 , 27 3 , are to be held prior to winding. Alternatively, the mandrel may be an electromagnet, as in the winding machine of Figs. 13 and 14. This mandrel is rotatable with shaft 65 and comprises nine steps 57 1 ... 59 9  between end-plates 63, 64, and includes an electromagnet winding 69. The wire 67 is fed during winding by a traversing guide 95 to wind each step in turn. A yoke 74 surrounds the mandrel and is traversed along it by lead screws 75. Initially, it proceeds from the smaller end of the mandrel towards the larger. As it does so, ferromagnetic element stores 78, 79 ride on rollers 84 on stepped members 164 in slots 70, 71 in the mandrel, whereby each step on the mandrel face dispenses an element from the bottom of a stack in its corresponding store, which element lies on the preceding step. When the yoke reaches the position shown, winding begins. When winding is complete, the yoke is traversed back, this time with legs 88, 88 1 , extended into slots 70, 71, so that the legs collect up the layers of windings and elements concentrically and push them over a moulding core 91. A moulding chamber enclosing the windings is then defined by core 91, and wall 92, legs 88, 88 1 , and sliding side members such as 86. Moulding compound is injected from chamber 87 through slots in wall 92. The winding is energized with A.C. current to accelerate curing by iron losses in the elements. After curing, core 91 is retracted to allow the finished winding to be removed. Sequential control of the various motors, solenoids, and current flows is achieved by a rotating drum, Fig. 16 (not shown), bearing contacts co-operating with fixed wipers.

Title: Improvements in or relating to magnetic core circuit arrangements
IPC: H03K3/45
Filed: 1964-09-16
Abstract: 1,063,650. Core stores. SIEMENS & HALSKE A.G. Sept. 16, 1964 [Sept. 16, 1963], No. 37778/64. Heading G4C. [Also in Division H3] In a circuit arrangement comprising a chain of magnetic core stages the arrangement of the windings assiciated with the cores is such that only the first of a plurality of preselected cores in the chain is switched by a clock pulse applied to all the stages to produce an output at that stage: As shown in the Fig. 1, each core K1, K2 is associated with a transistor bi-stable circuit Tr1 Tr2 and initially all the cores in the chain are placed in the " 1 " state by closing switch SO and passing current through the block windings W1. The switches S1, S2 &c. of the cores which are not to be marked or selected are closed so that these cores are switched to the " O " state and those of the cores to be marked are left open so as not to be switched. A subsequent clock pulse T from generator TrO, which by itself is insufficient to cause a core to switch from the " 1 " state to the " O " state, on clock pulse windings W1 causes the marked cores K1, K2 in the Figure to move towards the " O " state so that the induced signal in control winding W3 causes transistor Tr1 to conduct. In view of the feedback winding W4 wound on the core the collector current of transistor Tr1 eventually switches core K1 to the " O " state and produces an output signal in an output winding (not shown). Since the feedback winding on core K1 is connected to the block winding W1 the collector current of Tr1 flows through block winding W2 of the second marked core K2 and prevents this core from being switched to the " O " state by the clock pulse T. The next clock pulse T switches the core K2 to the "O " state since core K1 is already in this state and no collector current from transistor Tr1 flows in block winding W2 of K2 to inhibit this core. The succeeding clock pulses will thus switch the marked cores in succession to produce outputs. In order that a clock pulse coincides with the collector currents in the block windings capacitors C are connected as shown to form a delay line with the clock pulse winding W1 to delay the clock pulses. In the arrangement of Fig. 2 (not shown), the windings W5 and switches S1, S2 &c. are omitted and the control winding W3 is connected to a pulse generator which supplies a bias to the associate transistor to render it non-conductive when the core is unmarked. In the arrangement of Fig. 5 a pulse is applied to the mark winding W5 instead of a steady bias prior to each clock pulse.
