As described the panels 5 are provided with grooves along their margins to mate with the channels. In addition to the strip forms shown in Figs. 2 and 4, the channel B of Fig. 4, may be closed off by a wall parallel to central wall 1 to form a cavity along the length of the strip and in each case the channel A may be omitted. As regards the Fig. 2 arrangement, the limb L may be omitted also.

IPC: G01V3/10
Filed: 1957-04-05
Abstract: 844,065. Locating conducting and magnetic materials. U. D. ENGINEERING CO. Ltd. April 3, 1958 [April 5, 1957], No. 11161/57. Addition to 800,782. Class 37. The circuit described in the parent Specification for responding to the approach of a magnetic or conductive body is modified to give discrimination between conductive and magnetic bodies and a trigger action. As in the prior case a Colpitts oscillator is coupled via capacitor 8 to the inner grid of a tube 2 (preferably a heptode in the same envelope as the oscillator tube) and a tuned circuit forming the probe is connected to another grid. According to the present invention a further connection is provided to supply to the latter grid a voltage from the oscillator of adjustable amplitude and phase sense via a resistive or capacitive potential divider 18. When this voltage is in one phase sense, the apparatus is sensitive primarily to magnetic material and when the phase sense is reversed the sensitivity is mainly to conductive material. In either case a trigger action takes place whereby the change in anode current of valve 2, which operates the indicating instrument, persists after the detected body has been removed until the circuit is broken or a body of the other type (magnetic or conductive) is encountered.

Abstract: 144,048. Pilblad, E. J., Tomlinson, A., and Imperial Typewriter Co. May.5, 1919. Tabulating-mechanism; key locks.-In tabulating-mechanism of the kind in which a rocking frame carrying stops is operated by a tabulating- key, the rocking frame is arranged, when engaged by the column stops, to move longitudinally and operate means for releasing the tabulating-key lock. As shown in Figs. 1 and 5, the column stops D<5> are mounted on a rail D secured to arms D<1> on a shaft D<2> which can rock in bearings D<3>, Fig. 5, on the framework and can also move longitudinally in opposition to a spring D<4>. The tabulating-key is formed on a push-slide F which is guided on a stud F' on the bar G and is provided with a depending arm F<1> engaging the arm E<1> of a clip E on the shaft D<2>. On pushing inwards the tabulating-key to the position shown in Fig. 4, the arms D<1> are recked and the column stops are brought into line with a stop L, shown in rear view in Fig. 5, on the platen carriage A; further, the carriage is released by means of a pillar F <7> on the slide F, which carries the feed-rack B cut of engagement with the escapement C, C'. The tabulating-key is locked by means of a catch-lever H pivoted on a stud H<1> on the bar G and connected to a spring H<4>, a nose H<2> on the catch lever snapping into a recess F<5> in the slide F. When a column stop engages the stop L, the shaft D<2> is moved to the left, and the arm E<2> of the clip E engages the tail H<3> of the catch-lever, and causes the catch-lever to release the slide F. The slide, upon being released, is returned by a spring and restores the stop-bar and the feed-rack to the normal positions. For releasing the tabulating- key by the action of returning the carriage to the starting position, there is provided a lever J pivoted at J<1> to the slide F and provided with a lug J<6> engaging the catch-lever H, and also provided with a pawl J<2> adapted, when the slide is pushed inwards, to register with a toothed bar K on the carriage A. When the carriage runs in letter-spacing direction, the teeth K<1> of the bar run idly over the pawl; but when the carriage is returned, the pawl is operative to rook the lever J and release the catch.
