Title: Logarithmic analog to digital converter
IPC: H03M1/44
Filed: 1966-01-19
Abstract: An analog-to-digital converter comprises a number of series connected stages each associated with a digit of a binary number, each stage comprising an amplifier, a switch being arranged either to connect the amplifier to the next stage or to connect a by-pass circuit to the next stage, the amplification of each stage being twice the amplification factor, measured in decibels of the next. The converter comprises three stages having amplifiers V1, V2, V3 the outputs being applied to threshold circuits for comparison with a reference signal R. If this is exceeded the corresponding switches S11, S31 operates and by-passes the amplifier. The switches also give digital output signals. The series connection causes the gains to be multiplied and since the amplification factors measured in dbs are related in the proportion 1, 2, 4 the binary number represented by the digital output is the logarithm of the input analogue signal. The threshold devices may be Schmitt triggers, and the switches may be replaced by a gating circuit (Fig. 4, not shown)
Patent ES-336895-A1 (ES)
Title: Densitometer analog-to-digital converter system
IPC: G01N21/27
Filed: 1967-02-16
Abstract: The optical density of a plurality of portions of a film is sensed by a photo-electric detector, the output from which is converted into pulses of frequency proportional to the amplitude of the detector output, the number of pulses counted in a predetermined time being used to obtain a record of the optical density of each portion of the film at the various positions. The film 296 is located in grooves 292, 294 in carriage 290 and a button pressed to initiate a series of measurements on the film. The carriage 290 is driven by a motor to move the strip 296 continuously or stepwise between a light source 304 and photo-multiplier tube. A particular measure - ment on a portion of the film is started when an aperture 300 in a member 298, which is moved along with the film, arrives between a light pipe (306, Fig. 3, not shown), guiding light from the source 304, and a photo-sensitive cell 302. This causes a relay (314) to become energized and a thyratron (310) to extinguish, producing a control pulse to a pulse counter (28, Fig. 1, not shown). The amplitude of the photo-multiplier output, representing the optical density of the film, is converted (24), into a pulse signal, the number of which pulses occurring in a predetermined interval, e.g. 100m sec, is measured by the counter (28). When the next aperture 300 arrives between light pipe (306) and photo-cell 302, the relay is again energized and a further control pulse issued to the counter (28) which simultaneously passes on the count attained in the measurement interval in binary-coded decimal form, resets to zero, and begins counting for the next portion of the film. The coded count is decoded (32) to decimal form and fed to a card punch (36) which initiates punching of a card to give a record of the optical density of the particular portion of the film. Manual control of the card punch is through an identification keyboard (54) and the card punch control unit (50). The colour of the light used may be changed as desired by positioning the required filter of a filter wheel (370, Fig. 4, not shown) in the light path. When this is done, a suitable resistor is switched into the lamp circuit to change its brightness to allow for variations in filter density and detector spectral response and a signal is fed to the card punch to record the fact that a particular filter is used. Automatic gain adjustment of the photomultiplier is provided.

Title: Interpolative sensor output visual map display system
IPC: G01K1/02
Filed: 1972-12-20
Abstract: A sensor output visual display system is presented for coherently displaying the output readings of a plurality of sensors, such as the in-core thermocouples of a nuclear reactor. The in-core temperature distribution, as detected by the in-core thermocouples, is displayed using light intensity modulation over a reactor core map - the brighter areas on the map corresponding to the hotter areas of the core. The active display area is divided into blocks, each corresponding to a zone within the core representing a fuel rod assembly. Interpolation for assemblies not monitored directly by thermocouples is provided for a coherent display. The interpolation is performed by a resistive plate or resistor matrix constructed to conform to the geometric configuration of the reactor core. The total temperature information is then processed to interface with the display media. A visual alarm feature is included to indicate thermocouple readings which are outside preset limits and for identifying the existence of defective thermocouples.

Title: Speed pattern generator for elevator systems
IPC: H02P3/06
Filed: 1973-05-16
Abstract: A speed pattern generator for elevator control which provides a time dependent speed reference pattern, with control over maximum jerk directly incorporated into the pattern itself. The speed pattern is developed by starting with a step signal whose two magnitudes determine maximum jerk. The specific magnitude of the step signal which is selected, and time spent at each magnitude of the step signal is determined by acceleration and speed feedback circuits. The step or jerk signal is integrated to provide an acceleration signal, and the acceleration signal is integrated to provide a speed pattern signal which, regardless of how fast the elevator system responds thereto, positively limits the maximum jerk.
