Filed: 1959-04-10
Abstract: 945,348. Conveyers. ELECTRIC & MUSICAL INDUSTRIES Ltd. April 11, 1960 [April 10, 1959], No. 12127/59. Heading B8A. Articles in a moving series, e.g. car bodies 2, 3, on a conveyer or production line 1, are diverted selectively to a different route or/and operated on selectively under control of apparatus which observes information marks of a predetermined kind on the articles and presents the combination of information received from a group of successive articles at any given time to a comparator 9, which compares the combination with a given combination to provide an output, when the combinations agree, for effecting a desired route selection or/and process selection affecting a predetermined article or group of articles in the series. The marks are preferably of a binary nature and comprise e.g. the presence or absence of a daub of whitewash on each article. According to the number of successive articles in a group being observed a chain code of desired length can be formed by the combination of daubs along the series. The daubs on a group of articles in the series are observed either simultaneously by photo-electric devices 4, 5 or in. sequence by a single photoelectric device and the information passed to either a pattern register, in the former case, or a shift register, in the latter case, so that the combination at any given time can be compared with the given combination in the comparator 9. The apparatus may be duplicated &c. where it is desired to read simultaneously marks of different kinds, or in different locations on the articles, for simultaneously selecting different functions, e.g. route selection and subsequent process control.

Title: Improvements in magnetic field indication means
IPC: G01R33/038
Filed: 1943-07-26
Abstract: 566,430. Magnetic tests. ARMOUR, A. M., and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. July 26, 1943, No. 12141. [Class 37] A device for continuously indicating magnetic field strength and, in some cases, field direction, comprises two co-operating magnetic members, or parts of members, arranged in such manner that, when disposed within an ambient magnetic field, the relative displacement between said members or parts, due to the action of mutually repellent forces induced in them, affords a continuous measure of the strength of the ambient magnetic field. As shown in Fig. 1, a shallow casing 3 of transparent insulating material has embedded in the base a magnetic rod 2, while a similar rod 1 is free to move inside the casing. When the casing is stood upright in a horizontal magnetic field, as shown by the arrow, the rods 1, 2 are magnetized in the same sense and the mutual repulsion causes rod 1 to rise in the casing against gravity action to a distance dependent on the field strength. A scale of field strengths may be inscribed on the casing. If instead of gravity control, rod 1 is biassed towards rod 2 by a non-magnetic spring, fields other than horizontal may be measured. In a modification, Figs. 3 and 4 (not shown), member 2 is in the form of a magnetic disc, closing the bottom of a cylindrical casing, and member 1 is cigar-shaped. In this case, member 1 aligns itself with the magnetic field to indicate its direction, and is displaced vertically to indicate field strength. In the form shown in Fig. 5, a magnetic spring 20 is enclosed in a transparent tube 21 and becomes extended when placed in a magnetic field due to the mutual repulsion of the individual turns, the field strength being indicated by the displacement of the free end 20<1> relative to a scale 21<1>. Zero adjustment is provided by a screw plug 22. In a further modification, Fig. 6 (not shown), a flat coil spring is used, the free end of which carries a long pointer co-operating with a fixed scale. The centre is anchored to a stud which is adjustable for zero correction.

Filed: 1972-03-17
Abstract: 1354231 Electronic timepieces SEIKOSHA KK 17 March 1972 [20 March 1971] 12638/72 Heading G3T  An electronic timepiece includes a timing pulse generator, logic circuit frequency dividers and counters and electrically activated digital time display. Fig. 1 illustrates a 12 hour cycle timepiece wherein the timing pulse generator 1b (which also incorporates a 1/n frequency divider and decoder) produces a timing pulse every time it receives a pulse from a time standard pulse generator 1a, one of which timing pulses is produced at outputs a 1  ----- an in turn. Shift registers 2, 3, 4, 5 memorize the timing pulses, each register having "n" bits of memory equal to the number of outputs of the generator 1b. Each pulse, e.g. the n<SP>th</SP>, (n + 1)<SP>th</SP> &c., from pulse generator 1b operates to shift the memory content of the shift registers 2, 3, 4, 5 to the right by one position. Halfadders 6, 7, 8, 9 count time by respectively adding the counting time signal output of each register respectively to an output signal from an OR gate 17 to produce an adding time signal. A carry register 10 memorizes temporarily a carry signal produced at an output 9d of halfadder 9 and supplies a carry signal to the halfadders when the next counting time signal is produced by the registers. A carry controller 11, operated by the outputs of the registers, controls the carry of each digit place of the time indication and produces an output comprising a carry signal stored in carry register 10 and a signal from timing pulse generator 1b. Outputs of the shift registers 2, 3, 4, 5, when decoded, cause selective illumination of display elements in a display 23. Time setting can be effected by operation of a select switch 29 which selects any terminal a 1  a 2  --- a n  of the generator 1b whereby any digit of time can be reset to zero upon closure of a reset switch 26. To advance the time indication of a digit selected e. g. that corresponding to a 1 , a switch 28 is closed and an output logic "1" signal is produced and memorized in time advance circuit 27. The output of 27 is fed to input 6b of half-adder 6 where it is added to the output of shift register 2 and a time advance is achieved. An initial error preventive circuit 12 is provided to prevent errors due to spurious signals or 'noise' from a power supply source to which the timepiece may be connected and which is signified by a counting time signal from the registers of too high a value. Upon this occurrence the circuit 12 resets the registers. A 24-hour cycle timepiece is described with reference to Figs. 2A, 2B (not shown). It is stated that with two more memory bits in the shift registers the date and day may be indicated, in addition to the ten places (digits) of the time indication with the circuits described, the first place of which is units digit of the millisecond and the last the tens digit of the hours.  The timepiece may also be used as a stopwatch.
