Abstract: The working parts of a flowing gas laser are enclosed within an airtight housing comprising a first plenum separated from a second plenum. Blower means comprising one or more modules is provided with gas inlet means for receiving gaseous lasing medium from the second plenum and gas outlet means for exhausting the lasing medium to the first plenum. Means defining a lasing region are provided with gas inlet means for receiving lasing medium from the first plenum and gas outlet means for exhausting the lasing medium to the second plenum. The blower means provides a differential pressure across the lasing region sufficient to provide the desired flow of lasing medium through the lasing region. Due to the action of the blower means, lasing medium is caused to circulate from it to and through the lasing region and back to and through the blower means. Heat exchanger means for maintaining the lasing medium at a desired temperature is coupled to a diffuser at the outlet of the lasing region and/or a diffuser at the outlet of the blower means.

Abstract: A syncrhonization arrangement is disclosed for synchronizing a receiver with a transmitter whose frequency is hopping through a sequence of predetermined frequencies arranged pseudo-randomly. The transmitter includes a time base circuit in the form of a string of dividers operated from a stable oscillator. One divider produces (in this example) a 28 bit synchronization signal which changes state once every sixty four hop frequencies. The 28 bits control a keystream generator which produces a pseudo-random output sequence controlling the transmitting frequencies. This 28 bit signal is formatted by repeating it several times successively, with its bits partially re-circulated to a predetermined extent each time, masking bits are added, and the result transmitted to the receiver on one of the hop frequencies. At the receiver, a correlator subtracts the mask, partially re-circulates the bits to offset the partial recirculation at the transmitter, and recognizes receipt of the 28 bits when successive groups of the resultant bits are identical (or do not differ by more than predetermined total error). The 28 bits are used to pre-set a divider at the receiver which then in turn resets the receiver's keystream generator, thereby synchronizing the receiver.

Abstract: A device for regulating the flow rate in the tube, e.g. in infusion- and transfusion assemblies. The flow rate can be regulated by twisting a portion of the tube by means of a twisting device. The tube comprises at least along the portion of its length which is intended to be twisted a plurality of separate or communicating flow passages. Between said flow passages there are provided distance members arranged about or forming an inner core in the tube about which the tube is twisted and which reduces compression of the tube. When the tube is twisted the free space between said distance members is gradually reduced in the twisted cross-section of the tube and by that a reduction of the flow area is obtained.

Abstract: Method for operating a frequency relay and frequency relay for carrying out the method which, via measuring transformers, senses the frequency of an electric power network, determines the value of the frequency and delivers an output signal when the frequency thus determined drifts out of a permissible frequency range. Specific to the invention is the method of determining the currently prevailing frequency of the power network. The measurement signal (y/< ANd >(t)) obtained from the network is transformed, after filtering (1) and digitizing (2), into an analytic model (4) in the form of a truncated Fourier series (y(t)), the coefficients of which are determined in a parameter estimator (3) which operates with a method of estimation (5) in accordance with the least squares method. Starting from model values, according to the invention a computation of the frequency can be carried out in a frequency estimator (6), the output signal of which, on the one hand, is returned as current frequency value to the parameter estimator and, on the other hand, constitutes a measure of the current frequency ( omega /< ANd >) when determining the limits of permissible frequency variations.

Abstract: An apparatus for detecting the presence of carryover particles in an upper region of a furnace, such as a smelt bed boiler, includes plural spaced apart detectors. These detectors monitor discrete portions of the interior of the furnace for the purpose of detecting carryover particles in such monitored portions. Signals indicative of the carryover particles are processed to obtain a count of the carryover particles. The carryover particle count may then be displayed. For example, the signals from all of the detectors may be averaged with trends and overall changes in count rates then displayed. In addition, the counts from the individual detectors may also be displayed to assist an operator in locating the source of excessive carryover particles in the furnace. An image sensor, such as a charged coupled device (CCD) detector, may be used to provide a visual display of detected carryover particles. The information on carryover particle count may be used in controlling parameters affecting the performance of the furnace directly, or indirectly by way of operator input.
