Abstract: 1332104 Television ROBERT BOSCH FERNSEHANLAGEN GmbH 26 Jan 1972 [30 Jan 1971] 3614/72 Heading H4F To stabilize the operating point of a video amplifier, a correction signal, derived by comparing the video signal at the amplifier output during the horizontal blanking gaps with the video signal at the amplifier output during the vertical blanking gaps, is applied to the input of the amplifier during the horizontal blanking gaps, the magnitude and polarity of the correction signal being such that the difference between the values of the video signals in the horizontal and vertical blanking gaps assumes a constant value which is preferably zero. The video signal in the vertical blanking gaps used in the comparison is preferably derived from the central third of the forward trace of the line periods in the vertical blanking gaps. In a colour television camera system, the three video amplifiers supplied from three vidicons are stabilized as above to ensure that their null operating points which occur in the horizontal blanking gaps of the video signals are equal to the black values of the video signals that exist during the forward traces of the line periods in the vertical blanking gaps.

Title: Electrostatic recording and reproducing apparatus
IPC: G11C11/22
Filed: 1955-09-20
Abstract: 824,973. Circuits employing bi-stable ferro-electric elements. PULVARI, C. F. Sept. 20, 1955, No. 3761/57. Divided out of 816,109. Class 40 (9). [Also in Group XIX] Each column and row lead of a ferro-electric information storage matrix is connected to the secondary winding of an individual pulse transformer which has separate primary windings associated with the read and write control circuits, the primary windings on each transformer being arranged in opposite directions so that read and write pulses of the same polarity have opposite polarizing effects on the storage elements. As shown in Fig. 1, sequential access to a 10 X 10 ferro-electric matrix is controlled by ten-position beam switching tubes 14, 15, the column switching tube 14 being stepped directly by pulses from a clock oscillator 19 when gate 17 is opened over a flip-flop 22 by an input signal on lead 20. Each time a scanning cycle is completed by tube 14, the row switching tube 15 steps to the next position. The input signal also feeds a driver generator 26 which applies pulses of the same polarity to either a read or a write control circuit 13, 12 according to the operation to be performed. The read and write circuits are coupled with the matrix columns and rows over gates 3, 5, a gate being opened by coincidence of a read or write pulse with a signal on an output lead 8, 11 of the beam switching tubes. These gates are shown in detail in Fig. 3 and comprise biased transistors 33, 33a and 38, 38a for each column and row respectively. The transistors associated with energized output leads 8, 8a and 11, 11a of the beam switching tubes are conductive and permit a read or a, write pulse to act in respective transformer primary windings 32, 35 or 32a, 35a. The induced pulses in the secondary windings 30, 34 of the two transformers are of opposite polarity, and since the primary windings of each transformer are connected in opposite directions, a read or write operation is effected on the ferroelectric element 29 at the selected column and row intersection in accordance with the instruction from driver generator 26. Interaction between the primary windings is prevented by rectifiers 41, 42, and the secondary winding circuits are stabilized and amped by resistors 31, 37. When a read-out pulse is applied to the matrix, an output is obtained across a transformer 51 or an impedance which is applied over a lead 27 and a read-out circuit 28 to a display 28a. The read-out information may be restored in the matrix if required by energization of the write circuit 12 over lead 53 and the driver generator. During read-out the effect of unwanted transients or noise, which arises in lead 27 from unselected storage elements effectively in parallel with the interrogated element, is minimized by applying a compensating pulse to the write circuit 12 of one third the value of the read pulse. Alternatively, for total compensation, a separate scanning arrangement may be provided which applies compensating pulses of the correct magnitude to the unselected elements.

Abstract: 124,043. Jaeghere, E. de. March 12, 1918. Limbs, artificial. - Comprises constructions oi wrist-rotating mechanism for arms. The upward movement of the fore-arm 2, Fig. 1, produces an axial movement of the link 4 which is transmitted to a toothed sector 22, Fig. 4, pivoted at 19. The rotation of the sector is transmitted to a pinion 16 through a guided sliding rack-bar 17 having two sets of teeth on adjacent faces. The hand is secured to the screwed end 13 of the shaft 10 which is rotated by the pinion against the action of a spring 24. The link from the sector 22 has a slotted screwed connexion 25 to the link 4, partly for adjustment and partly to render the wrist-rotating mechanism inoperative when desirable, by loosening the screw. The sector may be operated by a tension cord secured to shoulder harness. A hand-pressed friction brake 34 may be used to retard the return movement of the wrist under the influence of the spring 24. Fig. 7 shows a modified construction in which the shalt 10 is rotated by a tension cord attached to a radial arm 40. A spring, connecting the, arm 40 to the casing, resists the movement and restores the shaft. The shaft 10 might be prolonged in some cases and the rotating mechanism fitted at points other than at the wrist. Specification 112,846 is referred to.
