Abstract: ABSTRACT Disclosed is a circuit for odd frequency division of a given pulse train which provides an output pulse train having a duty ratio of fifty percent.  For (2N-1) division (N is a plural number), N-delay type flip-flops are connected in cascade to form a shift register, each flip-flop having a signal input terminal for receiving a pulse train to be shifted, a clock input terminal for receiving a clock pulse train for shifting the pulse train at the signal input terminal, a non-inverting output terminal and an inverting output terminal. The output from the inverting terminal of the last flip-flop is fed back to the signal input terminal of the first flip-flop.  An Exclusive OR circuit has a first input terminal for receiving a pulse train to be frequency-divided and a second input terminal for receiving a pulse train from the inverting or non-inverting output terminal of a predetermined flip-flop of the shift register. The Exclusive OR supplies a clock pulse train for frequency dividing to all the clock input terminals of the shift register so that first and second output pulse trains are produced from each of the flip-flops of the shift register.

Abstract: RCA 74,739 Abstract of the Disclosure A multiplexing arrangement enables a plurality of control voltages for controlling respective ones of a plurality of varactor controlled tunable filters, employed, e.g., prior to the tuner of a television receiver to reject undesired signals t to be generated by a single digital to analog (D/A) converter.  A controller, which may, e.g., comprise a microcomputer, sequentially applies digital control words to the D/A converter and substantially synchronously causes the resultant control voltages generated by the D/A converter to be applied, through respective switch to the tunable filters.  The control voltages are applied to capacitors connected to d.c. control lines for the tunable filters.  The high impedance of the varactor diodes included in the filters enables the capacitors to store respective control voltages for relatively long intervals before the control voltages need to be refreshed.  This enables a large number of tunable filters to be controlled by a single D/A converter.

Abstract: WEIGHT-SENSER CALIBRATION FOR GRAVIMETRIC COAL FEEDER                         ABSTRACT OF THE DISCLOSURE                      A device for selectively applying a test load to a weight-sensing control mechanism in an enclosed conveyor unit for feeding particulate material at a controlled rate.  The weight-sensing mechanism continuously senses the weight of a variable quantity of material such as coal being conveyed through a predetermined reference zone and one or more load cells generate a voltage signal representative of the weight being sensed. The test load may be supported in the conveyor unit in either of two positions including a first position wherein it is supported independently of the weight-sensing mechanism and a second position wherein it is transferred to the weight-sensing mechanism for the purpose of calibration. The device includes a transverse shaft journaled in the con-veyor unit and a pair of eccentric hubs mounted at opposite ends of the shaft, each hub being rotatably received in a connecting head portion of one of a pair of support rods adapted to suspend the test load.  Thus, rotation of the shaft and eccentric hubs causes the test load to be trans-ferred between its two positions so as to transfer the weight of the test load to the weight-sensing mechanism for the pur-pose of calibration.  The transfer is accomplished by an operator at a location outside the enclosed conveyor unit.

The degree of mis-match which would be obtained between a test and a reference signal, for example speech signals, should their time axes be subjected to that relative shift and/or distortion which is required to minimize the degree of mismatch is carried out by sampling the two signals at regular intervals and storing these samples in memories (12 and 14 respectively). By means of address counters (2, 4) all the samples of one signal are then read out in succession from one memory (12) each time each successive sample of the other signal is read out from the other memory (14), and the difference between each pair of samples is formed in a subtracter (16). Each difference value from the subtractor is added to the smallest of three quantities X, Y and Z determined in a device 26 and the result stored in a register (20) to form the new quantity X. This new quantity X is also stored in a further memory (22) cyclically addressed in tandem with the memory 12. The quantity Z is -the previous content of the location of memory 22 into which the new quantity X is written, and the quantity Y is the previous value of the quantity Z, obtained by shifting the pre-vious value of the quantity Z in a two-stage shift re-gister (24), Thus the quantities X, Y and Z correspond to the present sample of the other signal and the immediately preceding sample of the one signal, the immediately pre-ceding sample of both signals, and the present sample of the one signal and the immediately preceding sample of the other signal respectively. The result is that each successive value of the quantity X is the optimum (i.e. minimum) cumulative distance value between the two sig-nals for the corresponding pair of samples should these be assigned to each other when matching the two signals to PHD 80-130                23    22.8.1981 each other. The process is continued until all the sampled values have been read from the memories 12 and 14 and paired, at which point the value of the quantity X is a measure of the above-defined degree of mis-match.

Abstract: : 17 :     ABSTRACT OF THE DISCLOSURE          A flame detector arranged to detect flames includes a non-microphonic infra-red sensor having a broad band frequency response.   To maximise the sensitivity to radiation from flames in the 4.3 ?m solar absorption band a narrow band optical interference filer, transmissive in the band 4.54 ?m to 4.38 ?m is chosen such that the integrated solar energy transmitted thereby is less than an alarm threshold.         A further filter prevents re-radiated heat from the filter reaching the sensor.   Another filter prevents radiation of wavelengths less than 4.38 ?m from reaching the other filters to reduce heating thereof and also to provide a series of filters to stop direct broad band transmission to the sensor through pin holes in the filters.   A signal processor detects flames by virtue of the flame flicker frequencies and includes provision for compensating for the effects of low frequency components on the amplitude of radiation produced by flames.
