Title: Improvements in or relating to battery discharge indicators
Inventor: GURWICZ DAVID
IPC: G01R31/36
Filed: 1968-05-17
Abstract: 1,271,497. Preventing over discharge of batteries. SEVCON ENG. Ltd. 30 April, 1969 [17 May, 1968], No. 23636/68. Heading H2H. [Also in Division G1] A battery discharge indicator incorporates a battery voltage sensing circuit which responds to the fall of battery voltage below a predetermined value to actuate an indicator, the system incorporating a switch which is actuated by a magnetic field generated by the battery current when this is above a given value so as to prevent actuation of the indicator. This ensures that the indicator will not be operated during temporary voltage drops due to heavy surge currents. In one arrangement (Fig. 1) a determined proportion of the voltage of battery 4 being monitored is tapped from resistor 15 and applied to one transistor 9 of an emitter coupled pair 7, 9. The other transistor 7 has a standard voltage from a Zener diode 1 applied to its base. Any changes due to temperature effects in the base-emitter voltage of 9 are compensated by similar changes at 7. If the battery voltage falls below a predetermined level, transistor 9 is switched off, current through the winding 13 ceases, and a pair of reed relay switch contacts controlled by the winding open. If however, there is a high current surge in the battery circuit to the load 6, a large field is produced in the winding 21 to hold the contacts closed. The contacts are used to control the operation of an indicator. In a second embodiment (Fig. 2) fall of the battery voltage is used to set a relaxation oscillator into operation. A proportion of the battery voltage is applied to the base of a transistor (37) whose emitter is normally held at the potential across a capacitor (43) charged from a Zener diode circuit (45). When the base voltage falls below the emitter, the transistor conducts and switches on a second (39) coupled back to the first so that the capacitor discharges and eventually prevents the first transistor conducting again. These oscillations are amplified and applied to a warning lamp (57). Heavy current flow in the battery circuit is used to operate a pair of contacts (61) across the warning lamp so that it is by-passed under surge current conditions. The first arrangement may be incorporated in a battery operated fork lift truck, operation of the contacts preventing the lift circuit from being operated.

Title: Control rods for nuclear reactor cores
Inventor: BELL FRANCIS ROBERT
IPC: G21C7/10
Filed: 1959-07-09
Abstract: 882,636 Nuclear reactor control rods. DE HAVILLAND ENGINE CO. Ltd. May 24, 1960 [July 9, 1959], No. 23681/59. Class 39(4) In a nuclear reactor having control rods passing through a pressure vessel into the core, the rods are adjustable so that the parts of a rod inside the vessel have a dimension perpendicular to the length of the rod and to the radius from a central axis of the core parallel to the length of the rod which is greater than the parallel dimension of the aperture in the vessel through which the rod passes. In this way the effective absorption of the rod is increased without increasing the size of the aperture. Fig. 2 shows a rod 12 with fixed neutron absorbing fins 13A and extendable fins 13B; Fig. 3 shows the extension mechanism comprising arms 17 forming part of a parallelmotion linkage, springs 18 for extending the fins, and rollers 24 for retracting the fins when the rod is withdrawn through the pressure vessel. The rod moves in a split guide tube fitted with guide rollers, Fig. 1C, not shown. Fig. 6 shows absorbing fins freely rotatable on a shaft 31, the fins being rotated through 90 degrees by a twisted slot as they pass through the pressure vessel. The control rods are preferably arranged parallel to each other in a circle so as to form a continuous wall within the core. Neutron absorbing materials mentioned are boron carbide; carbides, oxides, nitrides, silicides and borides of rare earth metals, e.g. hafnium oxide or carbide, or oxides of Gd, Eu, Sm; they may be dispersed in a refractory or sheathed in a refractory metal, e.g. stainless steel.

Abstract: 362,478. Preventing overhearing. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Aug. 7, 1930, No. 23724. Convention date, Aug. 23, 1929. [Class 40 (iv).] Two methods are described for rendering the cross-talk between lines transmitting in opposite directions unintelligible. In Fig. 1, speech over one line causes a buzzer or other noise producer G1, G2 to be applied to the other line to mask the cross-talk currents by means of a relay or other switching arrangement R1, R2, which is rendered ineffective by means of apparatus A1, A2 when speech starts over the other line. In Fig. 2, the speech currents in one line are inverted as regards frequency by means of apparatus U, the lower side-band resulting from the modulation of a carrier frequency equal to the highest speech frequency being transmitted, so that the cross-talk currents in the other line, which are inverted only once, are unintelligible.

Title: Digital data-processing systems
IPC: G06F12/02
Filed: 1974-05-29
Abstract: 1477381 Data processing systems SPERRY RAND CORP 29 May 1974 [30 May 1973] 23798/74 Heading G4A The system is organized to operate with words of a fixed length and includes a character addressing means which is enabled or disabled according to the value of a bit set by a program instruction and which, when enabled, addresses a holding register which contains a word read from a main memory, in order to obtain a character from that word. The memory comprises a number of independent registers, each of which can store data and an instruction word. If the bit D4 of the d-field of processor state register 100 is set, in a manner similar to that described in Specification 111,689 an operand address u from an instruction word register 110, Fig. 13a, 13b is added at 190, 198 to the base relative address BI of instruction words, to the base relative address BD of data words, and to an index value Xm. Value Xm is obtained from an X-register 138 selected by the x-field of the instruction word. The results of the first two additions are added to Xm to provide sums which are added to a word offset value Ow obtained from a J-register 132 selected by the j-field of the instruction word. The result of the third addition is also added to Ow at 156. The output of adder 156 is compared at 242 with a memory area divider BS to determine which of the adder outputs 250, 262 shall be passed to translation unit 260 to select an absolute address in the instruction area or in the data area of the memory. The required word is read out to a holding register 278. A character in the word is selected at 82 (described with reference to Fig. 14a, 14b, not shown) in accordance with the character off-set value Ob and control bits M and W from the J register 132. The M and W bits together specify one of four character sizes (e.g. 6, 9, 12, or 18 bit). The required character is automatically justified to the decimal point and passed to register 292. Dependent on the E-bit from the J- register unused sections of register 292 may be filled with the sign bit. When a character is to be written in to the memory it is placed in register 296. Unit 300 (described with reference to Figs. 15a, 15b, not shown) moves the character in accordance with the character offset value Ob and the character size bits M, W to properly position it within write unit 308 for writing into an absolute address selected as indicated above. Character addresses can be incremented or decremented to provide a sequence of characters of selected size. Word and character offset values are combined with word and character increment values to determine the next character location to be addresed, and permit the addressing of sequences of characters that are not adjacent in the memory. The operation is described with reference to Figs. 16-18 (not shown).
