Title: Low-friction means for conveying electric current between relatively rotatable elements
IPC: H01R39/64
Filed: 1963-10-18
Abstract: 1, 061, 282. Gyroscopic apparatus. SPERRY RAND CORPORATION. Oct. 18 1963 [Oct. 18, 1962], No.41349/63. Heading G1C. In gyroscopic apparatus having a rotor case 11 journalled in a supporting gimbal frame 13 for angular movement relative to the frame 13 about an axis 16, electrical current is led from the frame 13 to the rotor case 11 by means of a first set of contact members 46 carried by the gimbal frame 13 which are in contact each with one of a second set of contact members 50 carried by the rotor case 11, the contact members carried by the frame 13 being caused to go angular oscillations about the axis 16 relative to the frame 13 and to the set of contact members 50 to reduce friction. The rotor case 11 is mounted for rotation in bearings 20, 21 of the kind disclosed in Specification 835, 630 and each comprise an intermediate rotatable ball race 23, 31 respectively. The gimbal frame 13 is journalled in a housing 12 and carries a motor 35 which is periodically reversed by a timing device 38, and which oscillates the intermediate ball races 23, 31 through gearing 36, 37, the races 23, 31 being provided with flanges formed with gear teeth for this purpose. Electrical power is fed from a source to slip rings 39 carried by the frame 13 and thence through diametrically opposed sets of brushes 42, 42', to slip rings 43 carried by an insulating disc 44 which forms the toothed flange of the intermediate race 23. The pressures exerted by the sets of brushes 42, 42' balance each other so that no resultant torque is applied to the rotor casing 11. The contact members 46 are mounted on a pillar 45 integral with the disc 44. The intermediate races 23, 31 and the electrical contact members carried by the race 23 are preferably oscillated through more than one complete revolution in each direction, though oscillation through an angle less than 360 degrees may be employed, in which case the brushes 42, 42' and slip rings 43 may be replaced by flexible leads. If desired, two sets of diametrically opposed contact members 46 may be provided.

Abstract: 905,682. Piezo-electric elements. SYLVANIA ELECTRIC PRODUCTS Inc. Dec. 18, 1959 [Dec. 31, 1958], No. 43170/59. Addition to 900,995. Class 40 (8). [Also in Group XL (a)] The electroluminescent device of the parent Specification is modified by the provision of a second pair of contacts 18 and 20 on opposite sides of the piezo-electric strip 10, of a polarized sintered mixture of lead titanate and lead zirconate, and spaced from the electroluminescent layer 24. First voltage pulses are applied between the contacts 12 and 14, each pulse producing a first elastic wave and an accompanying first electric field which travel along the strip 10, and second voltage pulses are applied between the contacts 18 and 20, each pulse producing a second elastic wave and an accompanying second electric field, a moving spot of light being generated in the layer 24 at a point corresponding to the point of intersection of the first and second waves. Under some conditions of operation several spots of light can be produced. The ends of the strip 10 are coated with a material, such as lead, to provide terminations 30 and 32 for absorbing, substantially without reflection, elastic waves from the strip 10 as described in the parent Specification. Means are provided to vary the amplitude of the first and second pulses, whereby the light from the spot is modulated, and means are provided to vary the relative timing between successive first pulses and corresponding successive second pulses to shift the point of intersection of the waves. The first and second voltage pulses can be of sawtooth form generated under the control of trigger pulses from a common source, to provide spike-like pulses in the electroluminescent layer 24, the recurrence frequency of the first pulses being varied by a voltage of sawtooth form and the second pulses being of fixed recurrence frequency.

Title: Character display apparatus

Filed: 1972-09-18
Abstract: 1407293 Cathode-ray tube displays SIEMENS AG 18 Sept 1972 [17 Sept 1971] 43179/72 Heading H4T In a display arrangement in which rows of characters are produced on the screen of a cathode-ray tube by intensity modulation of a line scanned raster each row occupying a plurality (seven) of raster lines, a circulating store SR2 (Fig. 1) supplies the data for a complete row of characters the same plurality of times via a character generator ZG, a shift register SR3 and a video signal generator VS controlling the display BS and in the interval, (three raster lines) between successive rows, data for a new row of characters is loaded into store SR2 from a store SR1 in which, during the display cycle controlled by store SR2, the existing data is circulated at least once. With this arrangement new data can be entered into store SR1 during the display period of one character row without the need to recirculate the data at the comparatively high line scan rate. A timing circuit TK controls the operation of circulating the data in each store SRI and SR2, of transferring data from SR1 to SR2 and the entering of new data into SR1. The latter data is supplied at the INF input to gate T1 and is entered at an address set up in an address register AR which is compared in comparator V1 with the count in an address counter AZ the output of V1, on equality of inputs, controlling gate T1 to enter the data and increasing the count in address register AR by one count. (During this operation the recirculation path of store SR1 is opened so that the existing data at the specified address is erased and likewise, during the loading of data into store SR2, the recirculation path of this store is also opened to erase the existing data). This method of addressing only allows the commencement of a text to be determined and when a character is required to be entered at any position the modification shown in Fig. 3 is employed. In this modification the address counter is divided into a location counter SZ and a row counter RZ and the  address register is divided into a location register SR and a row register RR co-operating with respective comparators V2, V3. By means of a further register LR the length of a row can be predetermined by setting a number between 1 and z (see Fig. 1) in LR and comparing this number in comparator V4 with the number in the location register SR the output of the comparator resetting register SR which then increases row register RR by one count so that the next data is displayed on the next row. This allows data to be displayed in short lines as shown for the various time indications in Figs. 4 and 5 which also show curves of time-varying measured values at various times the values progressing downwardly as time increases.
