Title: Improvements relating to Apparatus for Reading Magnetic Tape
Inventor: MONTGOMERY JOHN YOUNG CONDIE
IPC: G11B20/18
Filed: 1967-08-08
Abstract: 1,193,287. Digital data storage. FERRANTI Ltd. 7 Aug., 1968 [8 Aug., 1967], No. 36260/67. Heading G4C. Words having n bits (including a parity bit and an end of block bit) are recorded on a magnetic tape 11 in blocks of N words, the blocks being arranged in pairs of which the second block is intended to be a repeat of the first. Circuit 18 responds to the end of block bit C6 to provide an end of block signal J and signals K, L distinguishing the first and second blocks B1, B2 of each pair. Parity check circuit 23 produces a parity fault signal PF if any word does not have an odd number of binary ones. Sequence check circuit 24 produces a sequence fault signal SF if a block read has the wrong number of words, as detected by OR gate 15 and counter 17. In the event of a parity or sequence fault being detected in the first block B1 of a pair, an attempt is made to replace the faulty data from the second block B2 of the pair. The following operations take place:- (1) If each word of block B1 is parity correct, the words are routed to store sections D1-D5 (only D1 is shown) by counter 17, stages S1-S5 by way of control unit 14 stages SU1-SU5. Block B2 is ignored. (2) If a parity fault is detected in any word in block B1, that word is not routed to the corresponding store section by unit 14, but the corresponding word from block B2 is, if parity correct, routed to that store section. (3) If a sequence fault is detected at the end of a block B1, all stages SU1-SU5 of unit 14 are reset and the words of block B2, if parity correct, are routed to store sections D1-D5. (4) If both blocks of a pair have a sequence fault, or if corresponding words in the blocks B1, B2 have a parity fault, unit 14 produces a fault signal F to reset the store and signal an alarm. Signal F is also produced if a parity fault in a block B1 is followed by a sequence fault in block B2.

Filed: 1959-10-27
Abstract: 926,981. Television. PHILCO CORPORATION. Oct. 27, 1959 [Oct. 27, 1958], No. 36374/59. Class 40 (3). [Also in Group XL (c)] The deflection waveform 25 which effects the vertical scanning component of a television picture tube 10 is also fed to the control electrode 12, so that, during-the occurrence of the flyback the beam is suppressed by the negatively going pulse portions 27. The effect of the positively going sawtooth portion 26 during the trace intervals is then neutralized by arranging that the sawtooth portion 26 alone is supplied to the cathode 11 and this is done by the action of an RC network comprising condenser 15 and resistor 17 which removes the pulse portions 26. The vertical flyback trace is then blanked out for all settings of the brightness control 16. Blanking of the horizontal flyback trace may be effected in a similar manner. When the deflection waveform has negatively going sawtooth portions and positively going pulse portions the complete waveform 25 is supplied directly to the cathode and the sawtooth portion (together with the video signals) supplied to the control electrode 12.

Abstract: 833,442. Steam engine &c. distributing valves; compressed-air engines. GORDON & CO. Ltd., J. March 25, 1957 [Dec. 23, 1955], No. 36989/55. Classes 122 (2) and 122 (3). A single-acting or double-acting reciprocating-type air motor comprises a piston 12, Fig. 1 whose movement is controlled by at least one piston valve 5 operating in at least one valve chamber 4, to the opposite ends of which equal pressure is applied through small apertures 17, 18 in the piston valve, and larger apertures 10, 11 and 24, 23 are provided in the motor cylinder 1 and motor piston 12 for the purpose of exhausting pressure alternately through relatively large passages 8, 9 from the ends of the piston valve chamber and so reciprocating the valve. The valve chamber 4 is formed in the removable head 2 of the cylinder 1 and receives, as shown in Fig. 1, a three-land valve 5. The valve chamber 4 is fitted with an exhaust port 16 and an inlet 15, communicating with the space above the piston 12 being through a port 13 fitted with a needle or other throttle valve 14. The piston valve 5 has an axial bore which is provided with the small apertures 17, 18 at its ends which give access to both ends of the chamber 4 to air entering the axial bore through a port 19. In the single-acting form, the piston 12 is returned by a light spring 22. In a double-acting engine, three-land piston valves may be provided at each end of the cylinder 1 or a single piston valve with extra lands may be provided to perform the functions of two separate valves, an exhaust passage then being provided through the piston-rod so that the interior of the cylinder may be connected to atmosphere during each exhaust stroke. In a modification, the ports 23, 24 in the piston 12 are axially spaced and register alternately at the ends of the stroke with opposed ports 10, 11 in the cylinder wall. In the modification shown in Fig. 3, the port 10 is opened as a spring-loaded ball-valve 10a is lifted from its seat by a shoulder at the end of an axial slot in the piston skirt to connect one end of the valve chamber to exhaust through a groove 24 in the skirt. As the working stroke begins, the ball-valve 10a is seated and at the end of the stroke a second ball-valve 11a is opened to exhaust the opposite end of the piston valve chamber 4. Fig. 5 shows diagrammatically how the reciprocating action of the motor piston may be converted to rotary motion by oppositely-directed pawls 25, 25a mounted on the forked limbs 22a, 22b of the piston-rod 22; rotation of a toothed wheel 26 on the driven shaft in either direction at each stroke is obtained by suitably directing the pawls, or for single action, one of the pawls may be disengaged to give unidirectional motion on each stroke.
