Title: Improvements relating to sawtooth waveform generators
Inventor: WHITE ERIC LAWRENCE CASLING
IPC: H03K4/32
Filed: 1948-05-27
Abstract: 655,725. Constant voltage control. ELECTRIC & MUSICAL INDUSTRIES, Ltd. May 27, 1948, No. 14294. [Class 38 (iv)] [Also in Group XL (c)] The waveform produced by a saw-tooth current generator (see Group XL (c)), is stabilized and linearized by comparing the voltage across the output coil with a steady voltage and feeding the difference voltage to a damping valve coupled to the coil. In the circuit shown the flyback is initiated by applying a negative pulse from the synchronizing source 48 to the grid of the driving valve 1 to cut-off the current from a source 2 flowing through the primary winding 3 of the output transformer. The output circuit then executes approximately a half-cycle of oscillation but the following part of the cycle is damped by a valve 13 connected to a second primary winding 12 to produce the first part of the forward stroke. The resulting voltage set up across the cathode resistor 14 of this valve is amplified and phase reversed in valve 39 and applied to the grid of driving valve 1 maintaining it in the non-conductive state until the damping valve current is insufficient to continue the sweep. The driving valve then conducts to complete the forward stroke. Constant amplitude and linearity of the forward stroke which demands a substantially constant voltage across the output coil is ensured by comparing this voltage with a steady voltage 32 and applying the difference to the grid of an amplifier valve 18, the output of which is further amplified in valve 19 and applied as a correcting voltage to the grid of valve 13 and hence also to the grid of valve 1. Any saw-tooth component of the output voltage is annulled before comparison with the steady voltage by making the time constant of resistor 30 and capacitor 34 equal to that of the inductance and resistance of the output coil 10. The amplitude of the wave generated may be adjusted by varying the value of the steady voltage 32. Specification 529,383, [Group XL], is referred to.

Title: Automatic typing system
IPC: G06F17/24
Filed: 1976-04-08
Abstract: 1499704 Selective signalling ING C OLIVETTI & C SpA 8 April 1976 [18 April 1975 29 April 1975] 14389/76 Heading G4H An automatic typing system comprises a keyboard for entering text information to be typed, means for recording the entered information on a record carrier and for reading the information, a printing unit operable to print out the information read from the record carrier, a control unit operable in a search mode to buffer a group of characters entered from the keyboard and cause information to be read from the record carrier with continuous testing for a match between characters in the information read out with the buffered group of characters, and further operable when a match occurs to terminate the reading, and a display device operable under control of the control unit to display the buffered group of characters during their entry and a consecutive fixed portion of the information read from the record carrier up to the last character read out, when a match occurs. The search mode can be used for searching for a text code or for a particular group of characters within a text. In either case, the group of characters to be found are compared in parallel with a corresponding number of characters from the record carrier, the latter characters changing progressively as the carrier is read. The comparands are held in shift registers and logic at the output of the comparator and responsive to a count of the characters entered from the keyboard (to be searched for) masks off those character positions not required in the comparison (each shift register and the comparator has 16 character positions, so if a sequence of 4 characters is being looked for, 12 positions are masked off). The "carriage-return" key on the keyboard is actuated (in entering a text) only at paragraph end, since during printing (from keyboard or record carrier) each line is ended at the first space or hyphen within a manuallypreset end-of-line zone. A number of paragraphs can be skipped during search mode by entering the number (from the keyboard) into the counter which is then decremented at each equelity between a character from the record carrier and the carriage-return code (inserted into one of the shift registers), until zero is reached. Keys also permit stepping back or forward by character or word, and deleting or inserting information by character or word when the required position has been located. The display device is a multi-character dot-matrix display, and the record carrier is a magnetic tape cassette, card or floppy disc.

Abstract: 1431371 Nuclear reactor pressure vessels BABCOCK & WILCOX Ltd 28 June 1973 [28 March 1972] 14513/72 Heading G6C A pressure vessel, e.g. for a nuclear reactor cooled by liquid sodium, is provided with an internal annular shield 10 which protects the inner face of the vessel from thermal stressing arising from changes in the surface level of the liquid sodium pool. In the embodiment shown the vessel comprises a concrete cylinder 1 and an internal steel liner 1a. The sodium pool is divided into an inner body surrounding the reactor core 2 and an outer, annular body in which heat-exchanger tubes 6 are disposed, the division being effected by an annular baffle 4. A pump 8 withdraws sodium from the inner body and discharges it into an annular trough formed by spaced surfaces of the liner 1a and shield 10 and a bottom seal flange 11. The sodium fills the trough and enters the outer body by overflowing over the upper edge of shield 10. The vertical height and disposition of shield 10 are such that the surface of the sodium in the outer body always lies at a level between the lower and upper edges of the shield. In modifications (not shown) (i) the sodium withdrawn from the inner body is discharged directly into the outer body, the trough remaining empty and having a cover to prevent sodium from entering it; and (ii) the sodium entering the through is derived from a sodium purification plant rather than directly from above the core.
