Title: Overhead travelling cranes
Inventor: PRITCHARD CHARLES MONTAGUE COR
IPC: B66C9/16
Filed: 1959-11-30
Abstract: 954,653. Overhead - travelling cranes. JOSEPH LUCAS (INDUSTRIES) Ltd. Nov. 28, 1960 [Nov. 30, 1959], No. 40552/59. Heading B8B. A crab 11 is driven along rails 10 by fluidactuated motors 13 and a carriage 19 is driven on the crab by a fluid-actuated motor 21, the three motors being supplied by a common pump, whilst a fourth motor 28, which operates a winch 27, has a separate pump. The motors 13 are connected in parallel and are controlled by a reversing and throttling valve and caused to work at the same speed by two proportioning valves. The motor 21 is also controlled by a reversing and throttling valve, the two valves being operated by a joystick arranged so that the resultant movement of the carriage 19 is in the same direction as the movement of the joystick. The pump which supplies the lifting winch 27 and an electric motor which drives the pump are located in the driver's cab 32. An additional boost pump may be provided for maintaining a predetermined pressure in the lifting circuit. Mechanism described in Specification 954,652 ensures that the crab 11 runs squarely on the tracks 10.

Title: Data processing system
IPC: G06F12/14
Filed: 1975-10-06
Abstract: 1529583 Data processing system XEROX CORP 6 Oct 1975 [29 Oct 1974] 40810/75 Heading G4A The description is similar to that of Specification 1,529,581 except that it contains additional material relating to the disc store controller. The claims relate to a microprogram controlled disc system including a disc controller operated under microprogram control, each command being verified as valid before being executed. The disc controller operates under microprogram control to read data from and write data on to a disc storage system including one or more double-sided discs. Three independent data blocks are recorded in each recording position along a disc track, the first two words including the address, the next eight words being a label, and the remaining 256 words being data. The data may be checked by comparison with that in the main data store except that certain words may be omitted from the checking in order to permit read and checking operations to be combined. A four word block in the main memory includes a pointer to a chain of disc commands, the controller idling when the pointer is empty, i.e. O. The disc commands consist of ten words which include a pointer to the next command, O indicating that this is the last command, status data, the command, disc address data, pointers indicating the location, or required location, in the main memory of the data, and words controlling the initiation of interrupts when the command has been completed. Each command accessed is verified as valid by comparing it with a verification word stored in a constant memory defore being executed. The discs are divided into sectors, e.g. 12 per track and sector and word signals are used to interrupt the microprogram (task switching, see Specification 1,529,581) in order to keep track of the addressing of the disc. Error signals also cause interrupts. The Specification gives some detail of the various circuits used in the disc controller.

Title: Sound analysing apparatus
IPC: G10L19/00
Filed: 1968-08-27
Abstract: 1,236,431. Speech analysis. INTERNATIONAL BUSINESS-MACHINES CORP. 27 Aug., 1968 [7 Sept., 1967], No. 40821/68. Heading G4R. Sound analysing apparatus comprises a plurality of devices for detecting respective sound characteristics, means for scanning the devices in cycles, and storage means, the outputs of the devices being stored in the storage means under control of a system receiving an exponential timing signal. A speech signal is split by a preamplifier into high, middle and low frequency bands which go to a fricative selector, harmonic locator and envelope peak detector respectively. The envelope peak detector provides an automatic gain control voltage for the preamplifier, and detects the fundamental to start a scan ring and a timing ring. The scan ring enables ten cup-andbucket scan counters in turn to count pulses from the harmonic locator. The outputs of the fricative selector and scan counters are fed to interlocked balance units which compare them in pairs (adjacent) to detect formants. Adjacent outputs of the balance units are combined in pairs in and-invert units, the parallel outputs of which are entered into a column of a storage matrix, successive columns being selected in turn for this by the timing ring. The matrix contents are displayed on lamps. A fricative (or sibilant) sound can also start the timing ring but advance by more than one step is inhibited until the fricative has ended. Similarly, if the fricative occurs in the middle of a speech signal, so that the timing ring is already advancing, this advance is inhibited until the fricative has ended. An exponentially-falling voltage is used to control a multivibrator which drives the timing ring so that the intervals between successive steps of the ring increase exponentially. A fricative (or sibilant) sound resets the exponential voltage to its highest value so that following storing of the fracitive (consonant) characteristics in the matrix subsequent fine (vowel) details are also stored by virtue of the intial relatively short intervals between steps of the timing ring.

Title: Detenting apparatus for electromagnetic indicator
IPC: G09F11/23
Filed: 1967-09-08
Abstract: 1,135,529. Digital indicators. PATWIN Inc. 8 Sept., 1967 [8 Sept., 1966], No. 41054/67. Heading G4H. An electromagnetic indicator comprises a panel 21 having a window 22 through which one of the numerals on a rotatable drum 33 may be displayed, a stator having an annular ferromagnetic core 28 and windings 29 whereby a magnetic field is established in one of a number of directions, a permanent magnet 31 rotating with the drum, the magnet being inside the core assembly, and the drum outside, the drum rotating, when the stator windings are energized, to present the selected numeral, a plurality of magnetizable detent elements 38A-38L in a circular array surrounding the core assembly and an indexing magnet 36 adjacent the detent elements, the detent elements being fixed, and the index magnet moving with the drum, or vice versa, so that attraction between the index magnet and one of the detent elements holds the drums in a display position after deenergization of the stator windings. In the form shown the core is toroidal, the windings being arranged to provide flux in ten different directions, to align the magnet 31 in the selected position. When the windings are de-energized, the indexing magnet moves the drum slightly to one side of the position given by the magnet 31. This ensures that the next energization will never call for a rotation of exactly 180 degrees. In another form (Fig. 11, not shown) the stator poles are radial, projecting inwardly from the stator core. One of them being energized to attract the pole of the permanent magnet. The other pole of the permanent magnet is displaced so as to lie between two stator poles on the other side. The annular stator core has a projection on the outside opposite each pole. These co-operate with the indexing magnet on the drum to retain the drum in the selected position.

The package core 2, Fig. 3, is supported by rolls 4, 5 on arms 3 that are biassed by a weight 8 to cause the package y' to engage a driving drum 1. The arm 19, at the instant represented, has pushed an empty package core 2' onto the arm 18 so that the empty package core 2' rests against the drum 1 and is brought up to speed. When the core 2 is fully wound control means 26, 27 causes the yarn to catch in a slot in the empty core 2' to cause the yarn to be severed and to wind onto the empty core 2'. At the same time a crank plate 15 is rotated to rock the arms 3 downwardly and cause pins 32 to strike a pair of arms 29, the resulting upward movement of the arms 29 lifts the completed package off the rolls 4, 5 and places it in the receiver 31. The arms 13 then swing upwardly to receive the core 2' and the cycle is repeated. An oil filled dash pot 10 prevents vibration and includes a compression spring that assists in supporting the package as it increases in diameter. In Fig. 9 (not shown) the arms 3 are actuated by a foot operated pedal. In Fig. 11 (not shown) the rolls 4, 5 are carried by the head 3 of a T-piece 57 that moves downwardly as the package grows. When the package is fully wound the head 3 is rocked about a pivot 59 to discharge the package.
