Title: Transmitting optical information
IPC: G03H1/32
Filed: 1974-03-26
Abstract: 1466425 Controlling light PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 March 1974 [29 March 1973] 13430/74 Heading G2F In a system where an optical image is formed by focusing a laser beam on a diffusing element S, e.g. a ground glass screen, and subsequently re-imaged by an objective 02 on a viewing screen P, granulation at P is reduced by placing at least one ultrasonically energized variable refractor T at some point on the optical path. As particularly described the image is produced by deflection at D of a beam from a laser G, but it may be derived from a hologram. In Fig. 2 the refractor T is a solid or liquid medium energized with ultrasonic waves of length approximately equal to the diameter of the granulation "grains" at that point, the resulting refractive index variations deviating components of the incident beam and giving an amplitude and phase re-distribution at the focal spot F. The rapidly charging granulation patterns at F are averaged by the eye. The larger the granulation grains, the more acoustic modulation is required, leading to an enlarged focal spot F, but for the same parameters, elimination of granulation is increased by increasing the aperture of objective O 2 . Elimination of granulation is better if an acoustic wave is used which is aperiodic over the short term, with a coherence length corresponding to that of the optical wave, e.g. by using further acoustic frequencies in element T or a subsequent cell with the same or a different medium. A second ultrasonic wave may propagate at 90 degrees to the first, to give granulation reduction with the same defocusing effect as for a single wave. As shown T is near O 2  but it may also be close to S or P with appropriate diminution of the acoustic wavelength. In a second embodiment; Fig. 3 (not shown), the element T is replaced by a prism, the position or shape of which is charged by ultrasonic waves so as to move the focal spot F over a distance greater than the diversion of a granulation point. The resulting rapidly charging granulation pattern is time averaged by the eye. The prism may be constituted by a quartz plate at acoustic resonance, so that there is a maximum variation in plate thickness at the centre of the plate. One half of the plate only is used as a prism of varying apex angle for the beam deflection. As particularly described, a pair of such plates acting at 90 degrees to each other are disposed between 02 and P and a further plate is disposed before S (M) to move the focus thereat. The pair of plates vibrate synchronously and with such an amplitude that the focus F is rendered stationary.

Abstract: 887,213. Bridge circuits. GARRETT CORPORATION. April 28, 1958 [April 29, 1957 (2)], No. 13475/58. Class 37. [Also in Groups XX, XXIX and XXXVIII]  A double bridge circuit for combining signals representing angle of attack and Mach number (see Group XXXVIII) comprises two potentiometers 45 and 66, adjusted in accordance with these quantities respectively, as the arms of one A.C. bridge whose unbalance signal is injected into a third potentiometer 80 in the second bridge which is completed by a fixed centretapped resistor 81. The output of this second bridge is amplified at 84 and fed to a motor 92 which drives a lead-screw 94 coupled to the slider of 80 until the combined output of the two bridges is zero. The amplifier 84 is of a type which gives an output signal the pulse length of which is proportional to the unbalance so that full rated power is applied to the motor ; stability is improved by an internal brake in the motor. In a modification (Fig. 2) the signals are set up on potentiometer sliders 202, 211 associated with a third potentiometer 220, as shown. The bridge output from the slider of 220 operates a motor 224 to shift the slider of a further centre-tapped potentiometer 227 so that a motor 231 will turn in one direction or another. The motor drives a pump 234 to circulate air around a closed system, and the ratio of the pressures across an orifice 237 adjusts the slider 220 to rebalance the system.

In a data processor, a decoder connected to a memory address register recognises the presence of a particular address in the register and in response gates the contents of a data register to the addressed memory location. In response to the detection of an error in the processor, said particular address is forced into the address register to store the contents of the data register in the memory. The contents of the address register are then successively incremented to cause the decoder to gate the contents of further registers and machine condition latches into the successive memory locations thus addressed. Detection of the last address to be so used, in the address register, allows the processor to continue. The contents of the memory locations mentioned can be read out to display lights or magnetic tape for the attention of maintenance personnel.
