Abstract: 707,768. Watches. HANHART, W. J., and HANHART, M., [trading as HANHART UHRENFABRIKEN, A.]. Sept. 20, 1951 [Sept. 20. 1950], No. 22041/51. Class 139 A watch for use also as a stop-watch has an auxiliary gear train to drive an auxiliary stop hand, a control hammer pivoted within the watch and operable by two members actuated from outside the watch case, one member operating said control hammer to disengage the auxiliary stop hand from the watch movement and the other member operating the same control hammer first to re-set the auxiliary stop hand at zero and then to re-engage the auxiliary stop hand with the watch movement. The normal seconds hand wheel, Fig. 3, meshes with a gear 3 carried by a resilient lever 4 pivoted by a screw 5 to the frame 6. The gear 3 may drive a gear 7 to which the centre seconds hand is fixed. The lever 4 has a projection 17 which co-operates with a cam surface 16 of a control hammer 10 pivoted by a screw 9 to the frame 6 and urged counter-clockwise by a spring 11. The member 10 has an extension 14 which co-operates, as described later, with a lever 20 pivoted by a screw 21 to the frame 6 and urged clockwise by a spring 22. In operation the gear 1 is driving the gear 7 and its centre seconds hand, Fig. 3. Depression of the button 27 rocks the lever 20 counter-clockwise. The member 10 is thereby rocked clockwise until the lever 20 engages a recess 19 in the extension 14, Fig. 2, At the same time the surface 16 engages the projection 17 of the lever 4 which is thereby moved to discharge the gear 3 from the gear 7 and so stop the centre seconds hand. Depression of the button 28 now rocks the member 10 further clockwise and an angled part 13, 14 thereof meets pin 15 on the gear 7 to zeroize the centre seconds hand. If now the button 27 is again depressed and the button 28 released the member 10 will be returned and arrested in the position shown in Fig. 2. A further momentary depression of the button 28 will release the lever 20 to return to its initial position by the action of its spring 22. The spring 11 will return the member 10 and the lever 4 will assume its initial position in which the gear 3 meshes with gears 1 and 7.

Title: Method for recognizing characters
IPC: G06V10/40
Filed: 1976-05-28
Abstract: 1515202 Character recognition DE STAAT DER NEDERLANDEN TE DEZEN VERTEGENWOORDIGD DOOR DE DIRECTEUR-GENERAAL DER POSTERIJENTELEGRAFIE EN TELEFONIE 28 May 1976 [2 June 1975] 22418/76 Heading G4R During a learning phase features of a number of representations of each of a plurality of classes of reference characters are classified into a number of groups of features and stored as statistical frequencies, during a recognition phase weights being derived for an input character for each possible feature in each group and the feature in each group having the largest weight being selected, the stored statistical frequency associated with this feature being multiplied by the weight and summed for each class of character, the character being assigned to the class having the largest value. As described for classifying handwritten characters, the groups comprise, for each of four aspects, jumps S, slopes H, end points EP and islands EL with each group comprising a predetermined number of types of features, the group of, for example, jumps having 7 features (no jumps, one positive jump, etc) and 7 corresponding weights, G0-G7. The size of the features is determined by examining successive lines of an image of the character, the weights being derived by formulae which take into account in a positive manner the size of the feature in the group associated with the weight and in a negative manner the size of features in the group not so associated.  During the learning phase, for each of the four aspects of the image, for each feature x of a character of class y (which may, for example, be the class of integers 2) the corresponding weight g x  is computed and within each group the maximum weight g x <SP>1</SP> is found by maximum selectors 11 (Fig. 14) and the count in storage position S xy  of a learning matrix 13 associated with the feature and class incremented by 1. At the end of the learning phase a logarithmic probability log K(y/x) = log S xy /#Sxy (where #S xy  is the sum of all the characters in the set for which feature x was selected) is stored at this position in the learning matrix 13. In the recognition phase for an input character the maximum weights g x  are computed for each group of features and normalized by dividing by the size B of the character in normalizers 14. The logarithmic values of the selected normalized weights are derived in circuits 15 and added to the value log K (y/x) (for all values of  y ) the result being stored in the column of matrix 17 assigned to the class  y  at the location associated with the feature x. For each class the stored values are then summed and the character is assigned by a maximum selector 18 to the class having the highest sum.

A control for a stepped change-speed gear comprises a servo means for moving a gear shift member in both directions in one line of movement and a control means for moving or controlling the shift member along a line transverse to the first line, the servo means and the control means being both electrically controlled by a first manual switch for up changes and a second manual switch for down changes, and a switching means for effecting a series of up changes when the first switch is held closed and a series of down changes when the second switch is held closed. The gear shift mechanism and its electrical control circuit is identical with that described in Specification 841,983 but the claims are directed to the manual control for up and down changes in the upper three ratios. These manual changes are overridden by governor valves on the gear-box input shaft to prevent downward changes at high engine speed and upward changes at low engine speed. Further overriding control provides enforced up change at high speeds and down shift at low speeds. In a modification, the single lever switch for reverse, low, automatic and manual 1, 2, 3 is replaced by push buttons controlling the change switches in the circuit. These push buttons are of the type which hold their position until another button is actuated.
