Title: Method of tuning the resonant circuits of a radio receiver
Inventor: MAIER GERHARD
IPC: H04B1/26
Filed: 1984-03-09
Granted: 1988-12-29
Abstract: A method and apparatus is provided for the tuning of the resonant circuits of a communications receiver. The frequency fD is generated with an additional oscillator, which frequency is then mixed with the receiver oscillator frequency, of which three frequencies fo, fo+fD, fo-fD are formed and are applied to the antenna output. The frequency fD, which is evaluated as a narrow band, is generated by mixing at the intermediate frequency output. A maximum balancing is provided over all high-frequency circuits. The acceptor circuits are tuned to fo and fo+fD (N+5, N+11) for obtaining maximum damping of the oscillator frequency and of the mirror frequency, where N+5 and N+11 represent mirror frequencies.

Title: Method and device to control a space heating installation, comprising a plurality of heat generators
Inventor: PICHOT JACKY
IPC: G05D23/20
Filed: 1984-12-27
Granted: 1989-03-09
Abstract: The present invention relates to a method and to apparatus for regulating a heating installation in a premises comprising a plurality of heating generators. The apparatus comprises temperature probes (10, 20, 140) which are sensitive to the outside temperature, to the inside temperature, and to the departure temperature of the heating fluid leaving the heating generators. The apparatus further includes means (50, 60, 70, 80 and 100) for determining a reference temperature on the basis of a set temperature (Tc) as indicated by a setting unit (30). A proportional-integral regulator (120), sensitive to the difference between the reference temperature and the departure temperature of the fluid, generates a signal which is applied to threshold detectors which detect the passage of said signal through successive predetermined thresholds, thereby generating successive signals for bringing into service the corresponding heating generator.

Abstract: Method for the operation of a multiprocessor controller, at least some of the processors (BP, CP, IOC, IOP) having access via first switches (S) and thus via each half (B:CMY0, B:CMY1) of a central inherently duplicated bus system (B:CMY) and second switches (SW) connected thereto to each half of an inherently duplicated main memory (CMY), or to each half (e.g. MB3a or MB3b) of one or more inherently duplicated memory banks (MB) of the main memory (CMY). In a special operating time, a redundant part of the controller is separated and interconnected to form a small, discrete, independently operating special processor by interconnecting individual redundant processors of this group (e.g. CP9 and/or IOC1) to one half (e.g. B:CMY1) of the bus system (B:CMY) and to a part of the main memory (CMY) or the memory banks (MB) in order to form an independent special processor for a special program, and continuing to run the so far normally operating program in the remaining parts of the controller, that is to say in the residual processor. The special processor later interrupts its special program. The components of the special processor are reconnected to the residual processor in such a way that only the normal operating program or a newly input modification thereof runs. <IMAGE>

Abstract: A complete prompt gamma ray neutron activation analysis (PGNAA) bulk material analyzer is self contained in a sealed and air conditioned housing. Bulk material is channeled by an open-ended vertical chute having a one-foot-by-three-foot cross-sectional dimension through an activation region between three neutron sources and two gamma ray detectors. The sources are symmetrically disposed on one of the three-foot- long sides of the chute from one end of such side to the other. The detectors are symmetrically disposed on the opposite side of the chute between positions opposing the positions of the sources on the one side of the chute. The chute is dimensioned to enable free flow of various bulk materials. It handles coal of up to a top size of four inches and with typical surface moisture contents and aglomeration characteristics. The relative disposition of the sources and detectors results in the measurements being independent of the lateral distribution of the bulk material within the chute. The signals produced by the detectors are continuously processed by signal processing equipment sealed within a separate compartment in the container to provide periodic measurements of the elemental content of the bulk material channeled through the activation region. A measurement of the bulk material channeled through the activation region during each periodic measurement interval is processed over several measurement intervals with the periodic elemental content measurements to provide weighted average measurements of the elemental content of bulk material over time periods representing average lots of the bulk material.

Abstract: The illumination device includes a charging part, an energy storage device, a flash tube and an amplitude control device, by means of which the energy storage device can be charged to different voltages. A time control device is superposed upon the amplitude control device. In consequence of the two control devices, the flash tube emits light with a predetermined color temperature as a function of the set amplitude and of the set flash duration. The color temperature can thereby be influenced in a controlled manner, with the maintenance of a very fine setting of the quantity of light, and can also be maintained constant independent of the quantity of light emitted.
