Title: Improvements in or relating to the manufacture of cast iron
IPC: C21C1/00
Filed: 1928-02-20
Abstract: 312,126. Elkington, H. D., (Meehanite Metal Corporation). Feb. 20, 1928. Purifying and refining.-In a method of producing cast iron from molten iron containing more than 2 per cent combined carbon or which when cast would contain more than 2 per cent combined carbon, and in which calcium is used as a graphitizing agent, the calcium is added to the molten iron in a quantity greater than that which would be neutralized by acidic or other constituents which may combine with it in order to leave free sufficient calcium to produce the amount of graphitization required. Another graphitizing agent such as another alkaline earth metal e.g. magnesium, may be added to the molten iron in addition to the calcium preferably after the addition of the latter. In an example 8 ozs. of calcium per 100 lbs. of molten iron is used.

Title: A voltage regulated supply circuit
IPC: G05F1/573
Filed: 1966-02-07
Abstract: 1,126,951. Automatic voltage control. COMPAGNIE GENERALE D'ELECTRICITE. Feb.7, 1966 [Feb.8, 1965], No.5365/66. Heading G3R. A voltage regulator is provided with an overload protection circuit and comprises input terminals E, E'; output terminals S, S'; a series regulating transistor Q1; a differential amplifier Q2, Q3 which controls transistor Q1 in dependence upon output voltage variations as detected by a voltage divider R4, R5; and a Zener diode Z which provides the reference voltage for the regulator and which is connected over a resistor R2 to the input terminal E and a resistor R3 to the output terminal S. In normal operation, the reference voltage is established by current flow through the Zener diode Z, this current being derived by way of the resistors R2, R3, and the output voltage at terminals S, S' is maintained constant in the usual manner. However, should an overload occur due to a short circuit, for example, the output voltage will fall and the current through resistor R3 will decrease; the current through Zener diode Z will then be insufficient to maintain the reference voltage and the current through transistor Q2 will also decrease, causing a consequent reduction of the current through transistor Q1 which is thus protected from the effects of the overload.

Abstract: 557,011. Helicopters. WEIR, Ltd., G. & J., and PULLIN, C. G. April 22, 1942, No. 5424 [Class 4] [Also in Group XXVI] The invention is concerned with the construction of jet driven blades and the provision of gas sealing means between relatively rotatable parts of the gas ducts through a helicopter rotor hub. Packing rings 52, 53 of moulded compressed carbon are secured within the upper and lower parts 48, 49 of a member tiltable upon a fixed hollow spherical support 47 which the packings closely fit. A hub 65 rotatable upon the tiltable member is sealed against gas leakage at its lower side by piston rings 71 carried by a ring 72 on the member 49. Similar rings 88 prevent escape of gases between each blade root 82 and a member 75 upon which the blade can tilt to vary the pitch of the ring system. The members 75 have belled ends bearing against spherical seatings 76 screwed into projections 74 on the hub and carbon-base packing material 77a is moulded into grooves in the seating against which the belled ends of the members 75 are pressed by springs 79 acting upon a ring 80 carrying a ring of frictional material 78. The blades are formed with a stressed skin stiffened by longitudinal spars 124, Fig. 6, the forward space 145 being D-shaped. At the root the forward portion is swaged to form a circular flared portion 116, 82 in which is secured an inner tube 114 for conveying the gases to the forward space 145 and to the nozzle at the blade tip. The space 145 is lined with insulating material and the skin is coated with an asbestos-base enamel. The spars 124 terminate in a bulkhead 144 braced to the tube 116 by a stay 140, a fairing 143 closing the inner end of the blade. In a modification the central space between the two spars is lined with insulating material having a forward air inlet 137. insulating material and the gases pass through it to an ejector nozzle 138, Fig. 13, having a forward air inlet 137.

Title: Improvements in or relating to nuclear reactors
Inventor: GRATTON CHARLES PETER
IPC: G21C7/02
Filed: 1964-02-11
Abstract: 1,029,712. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Feb. 11, 1965 [Feb. 11, 1964], No. 5624/64. Heading G6C. A nuclear reactor core has fuel-containing zones including fissile material and moderator to form a critical assembly having an epithermal neutron spectrum, and fuel-free zones bounded by absorbing material of predominantly thermal captive characteristics; provision is made for introducing moderator into the fuel-free zones so as to thermalize neutrons in these zones so that they are then absorbed by the absorbing material. The reactor is preferably water cooled and moderated, although the moderator may be solid graphite rods, particles or a slurry and the coolant a gas. Both shut-down and power control are effected by varying the level of moderator in the fuel-free zones or various parts of the zones, and this control may be supplemented by the inclusion of burnable poisons. Liquid moderator may be introduced from above or below the core. The reactor is stated to be particularly suitable for marine propulsion. The reactor (Fig. 5) comprises a core 51, heat exchangers 52 and a control system 63, 66, 70. The core comprises (Fig. 1, plan view) fuel assemblies 5, comprising vertical fuel plates, arranged in groups of four to define square fuelfree zones 6 which are lined by square section tubes of neutron absorber, such as boron-steel, or a cadmium alloy. Water coolant is circulated by three pumps 57 as indicated by the arrows. Immediately surrounding the core is a moderator container 56 which is intended to keep the core totally immersed in the event of a major leakage in the coolant system. A thermal shield 54 is also provided. Operation and control.-In the shutdown condition, all the moderator control channels 66 are filled with water via conduit 68a, 68b, 69; thus fast neutrons, which would normally pass through the empty channels, are moderated to thermal neutrons and consequently absorbed by the preferential absorbing material of the tubes. At full power, all water in the control channels is displaced by gas supplied through conduits 70 in tunnel 63; thus no moderation takes place of fast neutrons passing through the control channels. The control channels are divided into annular zones so that different levels of moderator may be induced throughout the core for optimizing flux distribution and start-up techniques. It is preferred to use the central region for fine control and the intermediate and outer regions for shut-down. The fuel preferably comprises 80% Pu 239, 16% Pu 240 and 4% Pu 241.
