Abstract: A method of treating an organic material such as textile fibres with an alkali metal hydroxide solution including the steps of:
     (i) contacting the organic material with the hydroxide solution to produce an effluent comprising an alkali metal hydroxide solution which contains multivalent ions and soluble and insoluble organic and inorganic matter;   (ii) reducing the pH of the effluent to a value in the range 7 to 9 by contacting with an acid gas;   (iii) filtering the solution from step (ii) to remove suspended insoluble matter having a size greater than 0,1 microns.   (iv) filtering the filtrate from step (iii) to remove multivalent ions and organic matter having a molecular mass greater than about 300 daltons;   (v) providing an electrochemical cell in which an anode compartment is separated from a cathode compartment by a cation selective membrane;   (vi) passing the filtrate from step (iv) into the anode compartment of the electrochemical cell;   (vii) passing an electrical current through the cell causing alkali metal ions to pass through the cation selective membrane and alkali metal hydroxide to be produced in the cathode compartment and the acid gas to be produced in the anode   compartment;   (viii) returning the alkali metal hydroxide to step (i); and   (ix) using the acid gas produced in the cathode compartment for reducing the pH of the effluent in step (ii).

Abstract: A conveyorized machine (5) that operates to automatically advance objects of generally the same shape and weight, particularly breasts of turkey, to a scale platform (8) which is retractable below the conveyor (7) and elevatable above the conveyor (7). On the scale platform (8) the object is automatically positioned to a desired location relative to a vertically running band saw blade (14). In one mode of the machine (5) the desired location will result in the object being sawed or severed into two portions of equal weight. In another mode the desired location will result in the object being sawed or severed into one portion of a predetermined weight and a second portion being the remainder of the object. After the object has been positioned in the desired position on the scale platform (8), the platform retracts or lowers below the level of the conveyor (7) and the object is then conveyed past the band saw blade (14) and the resulting two severed portions are conveyed to the discharge end (20) of the machine (5). Prefer­ably, a hold-down mechanism (11) is provided to securely hold the object in its desired position on the conveyor (7) as it passes by the saw blade (14).

Abstract: A translinear static memory cell employs both bipolar and metal-oxide-semiconductor technologies. Bipolar transistors are employed as switching devices, whereas MOS transistors provide power supply and coupling functions. Among other advantages, the bipolar transistors provide large changes in output current for small changes in input voltage, thereby enabling high level read signals to be obtained. The MOS load and coupling transistors facilitate bidirectional current flow into and out of the cell, thereby enabling write operations to be achieved during relatively short periods of time.

Abstract: In order to achieve increased resolution and to minimise cross-colour and cross-luminance effects in a PAL, NTSC or SECAM encoded signal, a high definition source (20) is pre-filtered at a higher line rate according to one of at least two methods (22, 24, 26). The filtered signal is sub-sampled (at 30, 32) at the source line standard where necessary, depending upon the degree of bandwidth reduction employed and one of the methods of pre-filtering and sub-sampling selected according (at 34) to a control signal (36) dependent on picture content. The luminance and chrominance components of the selected encoded signal are band pass filtered (46, 50, 52) and the chrominance signal modulated onto a sub-carrier (54) such that the frequency spectrum of the luminance and chrominance signals do not overlap.

Abstract: A first embodiment of the present invention has toroidal current transformer 11 having its outputs connected across full-wave bridge rectifier 12. The induced, rectified current produced by full-wave rectifier 12 is converted to a voltage by a load resistor. This voltage is compared to a reference signal, the magnitude of which corresponds to a quiescent current level, by comparator 13. When the load resistor voltage exceeds that of the reference voltage, a current surge is detected. The output of comparator 13 is directed to a retriggerable monostable multivibrator 14 which produces an activation pulse of a selectable and known duration. The activation pulse is directed to an electromagnetic or solid-state relay 16 which activates peripheral device 2 by connecting it to its power supply. 
     The second embodiment of the present invention has line sensor 18 electromagnetically coupled to power supply line 3 the output of current sensor 18 is integrated by integrator 19. The integrated signal is then digitized by digitizer 20 and input into selector 21. A crossover detector 28 and line voltage sensor 25 are operably connected to power supply line 3 to monitor the crossover points and voltage level of the supply. The monitored voltage is digitized by digitizer 27 and input into selector 21. Selector 21 alternatively supplies microcontroller 22 with the digitized line current and voltage level values. Microcontroller 22 compares the relative values of the line current and voltage level to detect current surges in power supply line 3 due to increased activity of parent device 1. Microcontroller 22 then activates solid-state relay 24, thereby activating peripheral device 2.
