Title: Electromagnetic induction micrometers
IPC: G01L3/10
Filed: 1923-06-07
Abstract: 215,986. Ford, J. M. June 7, 1923. Addition to 166,317. Magnetic measurements.-In the apparatus described in the parent Specification for measuring small relative movements, measurement of the relative displacement between the two elements of the normally balanced magnetic system is effected by providing a second similar normally balanced magnetic system in which the equilibrium may be disturbed by hand or otherwise by the same amount, as determined by a null reading of an indicating instrument. As shown applied to a torsionmeter, two similar laminated iron members 4, 5 are carried by one of the relatively displaceable flanges on the shaft, to the other of which is attached a laminated iron member 7. A similar magnetic system comprises two fixed members 29, 30 and a member 23 movable by a screwed spindle 25 having a scale 27 by which the movement of the member 23 can be measured. The windings 11, 12, 20, 21 on the members 4, 5, 29, 30 are connected in series with each other and with a source of alternating or intermittent direct current. Secondary windings 13, 18 are wound on the members 7, 23 and are connected in opposition and in series with an alternating-current indicating instrument 19. The primary windings 11, 12, 20, 21 are so wound that normally equal and opposite electromotive forces are induced by the secondary windings 13, 18. Displacement of the member 7 due to torsion of the shaft under test disturbs the equilibrium of the system and causes an electromotive force to be induced in the winding 13. The member 23 is then displaced by hand or otherwise until an equal and opposite electromotive force is induced in the winding 18, giving a null reading on the instrument 19. The displacement of the member 18. as measured by the scale 27, is then equal to the displacement of the member 7. The instrument mav be balanced when a propeller shaft is subjected to its normal full-load torsion, in which case the instrument 19 may indicate fluctuations in the normal torsion by defection on either side of zero. When the current in the secondary circuit is zero, the indication is independent of fluctuations in the voltage of the source supplying the primary current, which source may be the ship's lighting circuit. The alternating-current instrument 19 may be replaced by a direct-current instrument, rectifying- means being included in the secondary circuit.

Title: Locks
IPC: E05B55/06
Filed: 1975-04-14
Abstract: 1504753 Lock LAPERCHE 14 April 1975 [18 April 1974] 15179/75 Heading E2A In a lock, the opposite sides of a followeroperated latch bolt 4 have a recess 28 to receive a control member e.g. a key and a locking tumbler 26 is movable by the control member between a first position restricting bolt movement and a second position Fig. 1 in which the bolt is freed the locking tumbler being urged into the first position by resilient means, e.g. spring 27. As shown, recesses 15 on the bolt are engaged by arms 14 of levers 11. Bolt 4 is urged to the position shown by springs 21 on levers 11. Followers 5 on opposite sides of bolt 4 are urged to the position shown by compression springs 9. On rotation of either follower 5 e.g. by a handle (not hown), teeth 17 thereon engage teeth 16 on hub 13 of lever 11 and thus withdraw bolt 4 to open the door, etc. Bolt 4 has a slot 19 for sliding on a guide post 20 and an extension 23 which engages an inwardly facing projection 31 on a tumbler plate 26. Tumbler 26 has projections 29 engaging slots in the lock casing for vertical movement. On engagement with the key before it enters recesses 28, tumbler 26 is moved vertically removing projection 31 from the path of bolt extension 23 when the bolt 4 is moved by the key forward to its locked position in which extension 23 abuts projection 24 extending inwardly from the lock casing. Tumbler 26 moves back under the action of spring 27 to replace projection 31 now on the other side of extension 31, preventing withdrawal of the bolt. When the bolt 4 is in its locked position, teeth 16 of lever 11 are out of the path of teeth 17 of follower 5 and cannot therefore be engaged thereby.

Title: Flaw detection apparatus
IPC: G01N21/90
Filed: 1965-04-09
Abstract: 1,056,652. Detecting flaws photo-electrically INTERNATIONAL STANDARD ELECTRIC CORPORATION. April 9, 1965 [April 14, 1964], No. 15239/65. Heading G1A. In an arrangement for illuminating an article and detecting flaws by means of a parameter of a time based video signal produced by scanning, the video signals from predetermined areas are blanked by the signal developed by scanning, in a manner identical and in synchronism with the scanning of the article, an illuminated mask having contrasting areas thereon corresponding to the areas which are, or are not, required to be investigated. Light may be transmitted through the article if transparent, or may be reflected from its surface and the rate of scan may differ over different areas. Additionally the video signals may be compared with a threshold voltage which is different for different areas of the article in order that the arrangement may respond only to flows of a size predetermined according to their location. A glass article over which the investigation is made by a circular scan is described with reference to Fig. 7 ( not shown), and an apertured mask for blanking the signals from areas of surface ornamentation 26, 27, is described with reference to Fig. 8 (not shown). The illuminated object is investigated by an image dissector 24, Fig. 2, under the control of a scan generator 37, and the beam from a flying spot scanner 34, also controlled by generator 37, develops a signal in a photo-multiplier 35 to operate a blanking gate 43 when the beam is outside of the areas defined by the mask. The different rates of scanning i.e. the spacing of scanning lines are determined by a deflection amplitude generator 55, under the control of monostable multivibrators 57-59 and a bistable multivibrator 60, the output signal 62 being amplitude modulated on the sinusoidal output of a generator 66 to energize the scanning coils 74-77. A wanted flaw signal from the image dissector, after passing the blanking gate is amplified and applied to a unit 89 which permits the passage of signals above a predetermined level, these being amplified and inverted, and added to a step function voltage 100 in network 102. The steps are also positioned by the outputs from the multivibrators 57-60, and the superimposed signals exceeding a predetermined threshold are detected in 104 and applied with the differentiated trailing edge of pulse T4 from multivibrator 60 to produce a reject pulse of fixed length at a particular time relative to the scanning cycle. Conventional transistors circuitry is described and component values are exemplified.
