Patent FI-891890-A (FI)
Inventor: HAELG BEAT
IPC: G01R33/06
Filed: 1989-04-20
Abstract: In a design variant, the device comprises a magnetic field sensor (1), a voltage/current converter (2) which supplies the magnetic field sensor (1) with a supply current (i), an amplifier (3) connected in cascade to the output of the magnetic field sensor (1) and a converter (4) which is connected to the output of the amplifier (3) and which is an analog/digital converter or a voltage/frequency converter. The amplifier (3) is a correcting network whose transfer ratio in the design variants is proportional to one of the factors (1 +  delta n/n) or (1 -  delta n/n). The amplifier (3) comprises an inverting amplifier made up of an operational amplifier, a feedback resistor and an input resistor. Its gain is proportional to the ratio of the resistance values of the two resistors which are diffused into a semiconductor material of the same conductivity type as that of the magnetic field sensor (1). The two resistors are close to the magnetic field sensor (1), are symmetrical with respect to it and have approximately the same dimensions as it. At the same time, n, the charge carrier concentration in the semiconductor material, and  delta n, the change in said charge carrier concentration (n) with time in one of the two resistors, is preferably equal to the charge carrier concentration (n) in the magnetic field sensor (1), and the charge carrier concentration in the other resistor is equal to a multiple of the charge carrier concentration (n) in the magnetic field sensor (1).

Abstract: A web guiding structure in a drying section downstream from a coating device, and having suspension and infrared dryers and with a directly preceding coating device for paper or board. A rigid beam-like chest-like web bend device with blowing elements is adapted to produce a pressurized gas cushion for the web for contact-free bending of the web in its direction through an angle between 50 DEG and 120 DEG , so that with an increase in its distance from the bending device, the web also moves away from the coating device. Following the bend device a heating device or a suspension device having beam-like, chest-like blowing air guide devices in each case produces a course of the web undulating in the direction of movement of the web (web valleys and crests extending in the transverse direction) on the upper and lower sides of the web. Further dryers are included, with radiation and/or a hot gas action, and are alternately arranged with drying devices in the form of infrared dryers and suspension dryers, alternating at least twice.

Abstract: The invention relates to a process and a device for generating edge stress in a windscreen in a windscreen- curving oven which comprises several successive preheating sections, a heating and curving section and a lift device for lowering the curved glass plate down for cooling on a lower web. A light-mass disc 14 for guiding the airstream, which disc intensifies the heating of the edge of the glass during the heat stage, has been mounted on the inner side of the bearing plate 11 for the edge form. During the cooling stage, the guiding disc 14 intensifies the cooling of the edge of the glass. In this way, the intensified heating and cooling effects can be applied only against a narrow edge region in order to generate edge stress.

Abstract: 1,129,502. Character display systems for cathode ray tubes. GENERAL ELECTRIC CO. 9 Jan., 1967 [27 Jan., 1966], No. 1120/67. Heading G4H. In a system for displaying alphanumeric information on a cathode-ray tube, a character generator 30, Fig. 1, operable under the control of clock 29, receives alphanumeric information in binary coded form and generates signals in response thereto suitable for providing a visual display on a C.R.T., these signals passing directly to the video signal circuits 64, 65 of the C.R.T. in synchronism with the video sweep control signals, also provided by clock 29. The character frame, Fig. 2, is made up of 16 lines each having 12 bit positions. The character is built up by brightening the beam at appropriate positions as shown in Figs. 3 and 4. The odd lines are scanned first, as shown in Fig. 3, and then the even lines, Fig. 4. The system comprises a main memory 61 and a buffer memory 62, the latter comprising a delay line and recirculating loop. The alphanumerical characters appear at the input sources 21, 22 in the form of six binary bits. The data is received in the main memory in serial form from source 21 and in parallel over six or seven lines from source 22. Command signals may be entered from source 22. The memory 61 is capable of storing a full page of text having 26 lines with 46 character positions in each. Each line of data is entered in turn in the buffer memory 62 and recycles eight times while the raster performs eight scan lines on the C.R.T. The character generator 30 accepts each six-bit character from the buffer memory 62, and a four-bit word from the timing clock 29 representing the raster line and it encodes these signals into a video information word. This word represents a cut through the character as shown in Figs. 3 or 4. About a hundred different such sections are generated by a segment generator for each line of the raster. The appropriate segment represented as a pattern of bits on twelve leads is selected by an appropriate output from a character decoder, which receives the six-bit input word from the buffer memory. The twelve parallel bits are applied to a serialiser, e.g. a shift register, and are used to brighten the beam as it traverses the character area. Each character is built up by the odd lines followed by the even lines and this is repeated eight times.

Title: A method of and a device for measuring small alternating signals
IPC: G01R19/00
Filed: 1961-01-12
Abstract: 975,564. Voltage measurement. CESKOSLOVENSKA AKADEMIE VED. Jan. 12, 1961 [Jan. 12, 1960; Jan. 14, 1960], No. 1290/61. Heading G1U. A method and apparatus for measuring small h.f. alternating signals by means of a radio receiver comprises means for applying the signal to be measured and a reference signal of known level and frequency near to that of the input signal to the input of the receiver, and measuring the depth of the amplitude modulation so produced, as the ratio of the alternating to the direct component of the signal on the output of the linear demodulator of the receiver, so that if the reference signal has constant amplitude the demodulated alternating signal level represents the input signal. Fig. 1 shows the waveform produced by the addition at the input to a receiver of a known reference signal of amplitude U r  from a source 2 (Fig. 2) and a signal of near frequency but much smaller amplitude U x  at the aerial input. The ratio U x /U r  is equal to the ratio of the alternating and direct components of the envelope and the value of the unknown input signal is determined by measuring the direct component U o  and alternating component U ac  of the amplified signal at the output of the receiver demodulator 4 energized from a block 3 comprising either a high-frequency amplifier, frequency converter and intermediatefrequency amplifier of a superheterodyne receiver, or a high-frequency amplifier of a directly amplifying receiver; either being A.V. C. controlled. The demodulated signal amplifier 7 may comprise a narrow band filter tuned to the difference between the reference and input frequencies (Fig. 3 not shown) and a manually operated gain control 8 is provided. In a modification (Fig. 4) the filtered alternating demodulation signal of Fig. 2 is rectified and compared with a reference D.C. source 18, and the error is amplified to drive motor 11 controlling an attenuator 12 in the reference signal supply to apply a reference U<SP>1</SP> r  to the input so that U ac  proportional to U<SP>1</SP> r /U x  is held constant and the attenuator setting represents the input signal U x . The servo system may be arranged to be unresponsive to rapid fading of the input signal so that the attenuator setting represents the mean input signal and U ac  represents the superimposed variations thereof, and a moving coil system may replace the motor.
