Abstract: 739,257. Clocks and watches. NICOLET WATCH CO., SOC. ANON. Jan. 25, 1954, No: 2187/54. Class 139. [Also in Group XIX] In a time-piece the winding-up knob is carried on its stem in a manner such that it may execute, with reference to said stem, a slight axial movement, said knob being rigid with a socket the inner castellated end of which may, according to the axial position of the knob with reference to the stem, co-operate with a member controlling a mechanism associated with the going train of the time-piece, be released from the latter so that the stem may be angularly shifted by the rotation of the knob and provide selectively for setting and winding without acting on said controlling member. The invention is described as applied to a chronograph wherein the column wheel is replaced by a cam 1, Fig. 1, to which is fixed a return to zero lever 2. The cam 1 is connected to a lever 20 pivoted at 21 and having a lug 20a, Fig. 2, which co-operates as described later with a member 26 fixed to the crown 27. The cam 1 also controls the lever 5, Fig. 1, carrying the intermediate chronograph wheel 8 and the lever 13 carrying the intermediate counter wheel 15. The cam I is retained in its three operative positions by springs 18, 19. The member 26, Fig. 2, is axially slidable in a core 25 screwed on the winding stem 24 and having a head 25a which overlaps the bore of the member 26 at 29. A spring 30 co-operates with two internal grooves of the member 26 to determine its two positions with respect to the core 25. In the position of the parts 27, 26, 25 shown, the crown 27 may be rotated to wind the mainspring. The crown 27 and members 26, 25 may be pulled outwardly so that rotation of the crown effects hand setting. If the crown 27 and member 26 are pushed inwardly from the position shown, the castellated end of the member 26 engages the end 20a of the lever 20 so that rotation of the crown 27 effects movement of the cam 1.

Title: Improvements in or relating to cathode-ray tubes
IPC: H01J29/74
Filed: 1943-02-13
Abstract: 570,213. Cathode-ray tubes. KLEM PERER, O. E. H. Feb. 13, 1943, No. 2406. [Class 39 (i)] An electron beam is deflected by passing it through an electrode 31, Fig. 6, which substantially surrounds the beam and has an obliquely formed end 5. The electrode may be associated with one or more electrodes 32, 33, 34 with complementary oblique ends, the direction of the plane of separation alternating as the sign of the deflection potential on,successive electrodes changes. Alternatively, the oblique end 6 may project into a larger cylindrical electrode 23, which may be a coating on the neck of the cathode-ray tube ; a disc 24 seals off the space between electrodes 34 and 23, leaving only a narrow gap. The shorter side 14 of an electrode may vanish altogether, the electrodes on either side being joined at this point. The electrodes may also be formed by cutting a circular cylinder or their cross-section may expand progressively along the path of the beam. Deflection in two perpendicular directions may be obtained by cutting the electrodes in planes at right angles, the electrodes 41, 42, 43, Fig. 7, deflecting the beam in one direction and electrodes 43, 44, 45 in the other direction ; three electrodes will suffice for this purpose, for example, electrodes 42, 43, 44 with gaps 6, 5<1> only. Alternatively, deflection in one direction may be by simple deflecting plates. The oblique end need not be plane, since it may be curved as shown at 60, Fig. 9, to equalize the deflection sensitivity over the whole range of deflection or to obtain some other desired law, or a simple circular arc may be used to give a lens effect. Specification 525,000 is referred to. Reference has been directed by the Comptroller to Specification 561,905.

Abstract: 1437161 Producing a difference image CONTROL DATA CORP 21 Jan 1974 [12 Feb 1973 28 Feb 1973 29 June 1973] 02731/74 Heading H4F The differences between two related images, e.g. radiographs of the same person taken at different times, are displayed by the method outlined in Fig. 6, signals derived from the images, e.g. by flying-spot scanning, being substracted at step (4) after corrections at steps (2) and (3) for differences between the two images caused, e.g. by the use of different equipment for producing the two images, different orientations of the equipment and the object being imaged, or, for chest radiographs, differences in the heart phase or the degree of inhalation of the subject. Selection of control point pairs in the two images, to allow the positions of corresponding features to be determined and so allow the signals to be processed to effectively warp one of the images into correspondence with the other image in step (2), may be done manually (by choosing pointpoint pairs or point-slope pairs) automatically, or semi-automatically. The digital encoding of the signals may be controlled to provide emphasis to, e.g. the lung region. The displayed difference image, on a cathode-ray tube or hard copy, may be gray for unchanged areas and black and white for areas which have altered. The images may be notionally divided into different areas the signal from which are given different corrections in step (3). The warp carried out in step (2) may use polynomial equations. Apparatus for carrying out steps (2) to (6) of the method forms the subject of Specification 1,437,162.
