Abstract: The invention relates to a three-stage switching arrangement for electrical message switching technology. In a known three-stage and non-blocking switching arrangement, the switching matrices, of which the individual stages are constructed, have different numbers of inputs and outputs. Thus three different models of switching matrices are required. The invention is based on the object of specifying a switching arrangement of the above- mentioned type in which the switching matrices of all stages are of the same structure. The object is achieved by the fact that, among other things, the switching matrices (G1...G16) are distributed to two switching networks (KF1, KF2), that the number of inputs (16) of a switching matrix is equal to the number of its outputs (16) and that the inputs and outputs (E001...E256, A001...A256) of the first switching network (KF1) are connected to the identically-named inputs and outputs, respectively, of the second switching network (KF2). The invention also deals with developments for being able to use the switching arrangement for transmitting digital signals having a bit rate of up to 150 Mbit/s. <IMAGE>

Granted: 1992-09-17
Abstract: An improved FM communication system is disclosed in which noise bursts and pops in the audio output of the receiver, due to weak and Rayleigh-faded signals, are minimized by selectively attenuating the audio signal in the receiver. The amount and rate of attenuation for the receiver noise reduction circuits is determined by a control signal derived form either the average discriminator noise at frequencies above 3 kHz, or from a received RF signal strength indicator, or a combination of both. The audio output is attenuated during weak signals or Rayleigh fades only when the attenuation control signal increases above a predetermined signal-to-noise ratio threshold. Also described are further improvements to noise attenuation devices used in combination with the receiver noise reduction circuits to enhance audio quality in particular applications, e.g., FM repeater systems which may incorporate multiple transmitters in a simulcast configuration.

Granted: 1993-03-04
Abstract: The invention relates to a method and a device for controlling the temperature of heating and cooling plants comprising a heat and, respectively, cold source with adjustable nominal temperature via a microprocessor-controlled control system, in which arrangement it is not the actual outside temperature detected by an outside temperature sensor which is used as reference temperature but a theoretical mean outside temperature stored at particular interrogation times of a calendar year which, in particular, is stored in the form of a family of characteristics in a non-volatile memory for one or several climatic zones. By correcting the stored values of the theoretical mean outside temperature, particularly on the basis of the thermal load of the system determined via the heating-up and cooling-down rate of the heat and cold source and, for instance, correction of the diurnal variation of the outside temperature on the basis of values which have also been stored, the nominal temperature of the heat and cold source can be controlled in such a manner that it corresponds to the effectively prevailing outside temperature conditions without requiring an outside temperature sensor. The device is correspondingly particularly advantageous with respect to its design, installation and taking into operation and from the economic point of view.

Abstract: A utility knife (10) employs a slide (16) having a cantilevered lever (138) for capturing a blade (18) therein. A leading blade in a reservoir (24) is capturable by the slide (16) using a tooth (158) resiliently affixed to the slide (16) which is positioned to enter a locking hole (82) in the blade (18). The tooth (158) may be withdrawn from the hole (82) in the blade (18) whereby the blade (18) may be removed for reversal and reinsertion or for discard. When the captured blade is removed, the slide (16) may be returned to the loading position for capturing the next blade from the reservoir. As long as a captured blade (18) is engaged by the tooth (158), the slide (16) is prevented from returning to the loading position, and the loading blade in the reservoir is prevented from advancing.

Abstract: The invention is a process for post-hydrogenating sucrose polyesters with hydrogen gas in the presence of a catalytically effective amount of hydrogenation catalyst, at a temperature of from about 250 DEG F (121 DEG C) to about 450 DEG F (232 DEG C). Post-hydrogenation can be used to make sucrose polyesters that are different from those made by esterification. Preferably, the hydrogen pressure is at least about 20 psig. Increased hydrogen pressure overcomes steric hindrance of certain kinds of sucrose polyester molecules, allowing more complete hydrogenation of the fatty acids.

Abstract: A pipe-lined raster image processor (RIP) contains a bus (80) and connected thereto a number of separate image processing components (30, 50, 60, 70) capable of undertaking a respective image processing task substantially in parallel with those undertaken by other of these image processing components. In addition, an arbiter (40) is also connected to the bus. The arbiter receives a request from anyone of the image processing components for service from another one of the image processing components. Then, depending upon the availability of the bus and the destination component, the arbiter defines a data path over said bus between the source and destination components, and thereafter initiates an information transfer over the bus and between these components. Once this transfer is complete, the destination component is then able to undertake its respective image processing task substantially independent of the tasks undertaken by both the arbiter and the source component. At this point, both the arbiter and the source component are free to perform other image processing tasks while the destination component is performing its respective task.
