Title: Vehicle Braking Indication
Inventor: HAMILTON REGINALD THOMAS
IPC: B60T17/22
Filed: 1965-05-04
Abstract: 1,154,314. Brake indicators; hydraulic brakes. R. T. HAMILTON and E. S. T. GARDNERPOWELL. 3 Aug., 1966 [4 May, 1965], No. 18613/65. Headings F2E and F2F. [Also in Divisions G4 and H1] In an electrical switch for indicating the state of a vehicle braking system, a spring tensioned electrical contact 7 is adapted to bear against an insulated section 10 of a two-part piston 9, and a spindle 12, extending from the piston 4, 5 through a bearing 8 in the central body 1 of the switch unit, is spring-urged into a position in which the contact 7 is urged against the non- conductive part 10 of the two-part piston to indicate the brake released position. Figure 2 shows the position in which the spindle 12 has been contacted by a part of the brake actuating means and the contact 2 now bears against the conductive section 11 of the two-part piston 9 to indicate the brake-applied position. Excess movement of the spindle 12 against a spring 15 will cause the contact 7 to take the position shown in Fig. 3 to lock the piston in its foward position when the brake applying means is released and provide the driver with an indication that the brakes are mal-functioning. The switch may be associated with a master cylinder actuating spindle (Fig. 5, not shown), a hand brake lever mechanism (Fig. 6, not shown), or a pedal operated mechanism (Fig. 7, not shown). In the third stage of the switch, the stop lights of the vehicle may be operated to give an indication externally of the vehicle to other road users that the brake system is defective.

Title: Method and apparatus for control of a nuclear reactor
IPC: G21C7/30
Filed: 1962-05-21
Abstract: 1,001,817. Controlling reactors. UNITED STATES ATOMIC ENERGY COMMISSION. May 21, 1962 [June 5, 1961], No. 19449/62. Heading G6C. Apparatus for controlling an overmoderated nuclear reactor (i.e. one containing greater than the optimum proportion of moderator to fuel) the reactor comprising a plurality of parallel tubes each containing a column of fuel elements and means for flowing water through the tubes in contact with the fuel elements, is characterized by means for separating the upstream and downstream halves of at least one column of fuel elements whereby water replaces fuel at the centre of the reactor and the reactivity is reduced. As shown in Fig. 1, a chain 34 engages a sprocket 33 mounted at the upstream end of each tube 11, the tubes 11 being surrounded by graphite moderator 10 and housing fuel elements 14 which rest on ribs 16a extending inwardly from the walls of the tubes. A cable 35 passes through each upstream half-column of fuel elements and is attached to the end of this half-column while a cable 42 passes through the entire column and is attached to the end of the column. The two cables 35, 42 are also attached to the chain 34. The fuel elements 14 are short tubular bodies 15 of natural uranium contained in protective jackets 16, the end elements of each half-column comprising special end caps 41 in recesses 40 of which balls 39 at the ends of the cables 35, 42 engage. To decrease the reactivity, at least one sprocket 33 is turned clockwise so that the cable 35 draws the upstream half of the fuel element column towards the sprocket 33 while the downstream half is freed from restraint by the cable 42 and is forced away from the sprocket 33 by the flow of water through the tube 11. Conversely, turning the sprocket 33 anti-clockwise causes the two halves to move towards one another and the reactivity is increased. The apparatus is of particular use in starting- up a reactor after a period of shut-down before the Xe<SP>135</SP> present has decayed. The Xe<SP>135</SP> is converted by neutron absorption into   X#<SP>186</SP> having a thermal neutron cross-section many orders of magnitude less than that of Xe<SP>135</SP> resulting in a period of rapid reactivity gainthe " start-up reactivity transient." In a graphite-moderated reactor, this is enhanced by the increase in the moderator temperature. As reactivity builds up, the two halves of the fuel element columns are separated just enough to hold the excess reactivity down to the level where the regulating rods can maintain control. The apparatus can also be used for fine control of the reactivity at any time needed. It may be used to flatten the flux in the reactor by separating the half-columns of fuel elements near the centre of the reactor where the flux is highest and bringing them closer together away from the centre of the reactor.
