Abstract: Abstract of the Disclosure A radiation collector having a flexible reflective wall which is deflected to a curved preferably paraboloidal configuration by application of differential pressures to opposites sides of the wall.  In one form of the invention, the reflective wall forms the back wall of an inflatable bag having a forward flexible wall through which radiation from a source passes to the interior of the bag for reflection by the rear wall toward an axis of the device.  In another form of the invention, the reflective flexible wall is the front wall of a vacuum chamber and is deflected rearwardly by the differential between a subatmospheric pressure in the chamber and atmospheric chamber at the front of the wall.  A structure extending essentially circularly along the periphery of the flexible reflective wall preferably restrains the peri-pheral position of the wall against constriction radially inwardly upon application of the pressure differential to the wall, in a relation causing the wall to assume an ultimate configuration corresponding more closely to that or a true paraboloid than if the restraining structure were not present.  Desirably, the pressure differential is predetermined and regulated to give the reflective wall a substantially exactly paraboloidal shape.

Abstract: PROGRAMMABLE AUTOMATIC CABLE EQUALIZER            Abstract The circuit has a gain section which includes a first AGC circuit.  The output of the gain section goes to a signal shaping section which includes a biquadratic filter, a summer, and a second AGC circuit.  The two AGC circuits are controlled by respective separate peak detectors and are noninteracting.  For "short" cables, only the first AGC circuit is active. For "long" cables, the first AGC circuit is set at its gain breakpoint and the second AGC circuit alone has active control.  The shaping section includes a biquadratic filter which is a tandem arrangement of a low-pass filter, an inverter, and an integrator.  The low pass output of the integrator is connected to the noninverting input of the a summing amplifier.  The input of the second AGC circuit is connected to the band pass output of the inverter, while its output is connected to the inverting input of the summing amplifier.  The input of the second peak detector is connected to the output of the summing amplifier and its output is connected to the control node of the second AGC circuit.  Operational amplifiers of the first peak detector, the low-pass filter, the integrator, and the summing amplifier are designed to be programmable by means of decoders to permit the equalizer to accommodate different data rates.

Abstract: RECOMBINATION OF LOW- AND HIGH-RESOLUTION SEGMENTS OF AN EXTENDED ASPECT RATIO PICTURE Abstract A television (TV) system having provision for automatically compensating for signal distortion which would cause artifacts at the point where high- and low-resolution portions of an extended aspect ratio, high definition TV display are joined together.  Compensation parameters are calculated at the TV receiver in response to a known test pattern transmitted during the vertical retrace interval of the TV display and then accessed and utilized to compensate received active display signals. The compensation parameters are calculated by first converting Y, I, and Q signals for the test pattern into digital samples and then processing these digital samples in a digital signal processor unit.  After the compensation parameters have been calculated by the digital signal processor, they are stored in a memory.  The received active display signals are compensated by accessing the stored compensation parameters during the active display time.  Each accessed compensation parameter is converted to an analog signal and is multiplied by received, Y, I, and Q edge signals and combined with the center signals to compensate for distortions.  In addition, the stored paramaters are also averaged over a period of time to stop transient conditions from affecting the stored value of a compensation paramater.

Abstract: ABSTRACT OF THE DISCLOSURE      An anti-impact safety apparatus for a robot includes a buffer mechanism disposed between a swivel arm and a working arm of the robot.  The buffer mechanism incorporates a converting mechanism which converts an electrical signal into a gas or liquid pressure.  When an impact load, such as axial load, eccentric load, or moment load, is applied to the working arm in operation, the impact load is absorbed by the buffer mechanism and is also detected by a sensor switch, and the operation of the robot is instantaneously stopped.  Thus, it is possible to protect the working arm and a function unit incorporated in the robot main body from the impact load.  In addition, it is possible for the working arm to be readily restored to its normal position when the eccentricity thereof produced as a result of the impact is corrected.

Abstract: 1,012,765. Automatic speech recognition; electric selective signalling. STANDARD TELEPHONES & CABLES Ltd. March 6, 1964, No. 9638/64. Headings G4H and G4R. [Also in Division G1] Apparatus for analyzing waveforms, e.g. for speech recognition comprises means for detecting reversals of polarity in the waveform, the periods between reversals being measured by counting pulses produced by a time scale generator. In Fig. 1, the zero-crossings of the waveform are used to obtained a succession of time periods. In Fig. 2 the points at which the waveform crosses positive and negative threshold levels are used to eliminate spurious reversals due to noise. The time scale, Fig. 3, consists of a series of pulses initially crowded together but becoming more widely spaced. This enables the same degree of accuracy to be obtained for short or long periods. The alternate positive and negative periods are arranged to pass pulses to separate counters. Over a given interval the number of periods of the same length, i.e. producing the same count, is counted in a threshold counter which gives an output if the threshold is exceeded. The outputs of these channel counters is an analysis of the input waveform and may be used to recognize the components of the input word signal. In the system of Fig. 8, the speech input is normalized at 87 and then separated into components as follows: circuit 88 indicates whether the sound is voiced or not; circuits 89 and 90 extract the first and second formants; circuit 91 extracts the fundamental frequency; circuits 92, 93 extract frequency groups associated with unvoiced sounds and circuit 94 extracts a consonant signal. In addition a threshold circuit 95 indicates the presence of a speech signal and circuit 96 indicates, from this, that the word has ended. The fundamental frequency is used in circuit 99 to provide control signals for the measuring process described above and also segmentation signals which serve to sample the measurements obtained at appropriate instants. Circuit 97 analyses the voiced sounds (vowels) using the first formant and the second if necessary. Circuit 98 analyses the corresponding unvoiced sounds. Both these circuits use the counting system described above. The vowel, for example, appearing as a series of short " part vowels " which are counted and stored, being read out when a predetermined count is reached to phoneme recognition circuit 100. This circuit, which also receives signals from circuits 88 and 94, consists of an array of resistors, Fig. 10, between vertical lines connected to the part vowel stores D1, D2 &c. and horizontal lines connected to a threshold comparator. One of the horizontal lines will receive a higher signal and this will identify the sound. Successive phonemes pass to circuit 101 to identify the word when the end of word signal appears from circuit 96.
