Abstract: 1,190,145. Cavity resonators; fluid-pressure servomotor systems. GENERAL ELECTRIC CO. Oct.25, 1968 [Nov. 24, 1967], No. 50696/68. Headings G3H and G3P. A cavity resonator 18 of the kind having a chamber 20 and tube 22 tuned to a predetermined frequency, has a nest of open ended capillary tubes 24 extending into the chamber to provide a vent with a fluid resistance which varies in response to changes in fluid temperature, thereby counteracting frequency drift which would otherwise occur as a result of fluid temperature changes in chamber 20 and tube 22. The resonator is incorporated in an apparatus for maintaining a motor 12 at a constant speed by comparing the oscillations fed to a phase discriminator 28 directly from a signal generator 10, with those fed by the generator to the discriminator via line 14, resonator 18 and line 26. Specification 1,133, 591 is referred to.

Abstract: 1,190,203. Magnetic separators. M. E. L. EQUIPMENT CO. Ltd. 30 Aug., 1967 [15 Nov. 1966], No. 51068/66. Heading B2J. Apparatus for removing swarf from coolant comprises permanent magnets subjacent an endless inclined belt 1, Fig. 1, over which the coolant is conducted. At or near the upper end of the path is a means for removing the swarf from the belt, which comprises a device having a continuous surface (viz a drum 19) movable into proximity with and away from the belt, and means to create at the surface a magnetic field to draw away the swarf. The belt 1 and drum 19 are chain-driven by a motor 7 and the magnets 5 and belt 1 may be driven at the same speed. The drum 19, Fig. 3, is of non-magnetisable material with central magnets 33 and sleeves 35, 36 serving as pole pieces. In operation, the swarf is carried by the belt out of a tank 10 up the ramp 2, and the larger pieces fall into a bin 45. Adhering pieces are removed by the drum 19 and detached by a scraper 41. Coolant is squeezed from the belt by a guide roller 20 and carried away by a channel 47. In a second embodiment the magnetic assembly is arranged eccentrically in the drum and remains stationary while the drum rotates. Thus the magnetic attraction of a particle diminishes as the drum rotates. The inclination of the Tamp 2 may be varied by a strut 48, and a stationary assembly of magnets may be used beneath the ramp 2.

The cam 18 has arcs 70, 71, 72, 73, 74, 75, 76 concentric with shaft 55 and ramps 70a to 75a between causing one increment of linewise movement. This increment corresponds to the spacing of adjacent rows of the character matrix. Ramp 78 causes a greater linewise increment corresponding to the spacing between matrices of adjacent print rows. Apertures 89, 90, 93 and sensors 27, 91 supply signals to the printer control. Synchronization of the rotation of shafts 44, 55 is by a predetermined choice of gears 56, 57 and pulleys 45, 46.

Abstract: 1524080 Automatic electric control POST OFFICE 2 Dec 1976 [16 Dec 1975] 51519/75 Heading G3N An annunciator system is responsive to sensors, indicating alarm conditions to actuate a cassette recorder which is controlled by an arrangement which selects a recorded message corresponding to the sensed alarm condition and initiates playback over a communication channel. In a first embodiment, alarm signals are fed through a priority encoder to a memory which outputs a position signal to a comparator wherein it is compared with an index signal derived photoelectrically by sensing reflective patches on a tape reel of the cassette. The rate of position-seeking is dependent (within eight messages) on the difference determined by the comparator on order to avoid over-shoot. In a second embodiment, a facility is provided for substituting a new message and in a third embodiment a photo-electric device detects transparent inserts in the tape at the beginning of each message and the take-up spool is sensed to detect tape movement.

Abstract: 1522260 Phase discriminators INTERNATIONAL BUSINESS MACHINES CORP 15 Dec 1976 [23 Dec 1975] 52381/76 Heading H3A In a phase controlled oscillator system, positive and negative constant current sources are switched to an integrator, which provides the error correction signal, at times determined by a reference input signal and the controlled oscillator output. The current sources are switched simultaneously to or away from the integrator in response to a predetermined condition and are switched individually away from or to the integrator in reponse to respective control signals. In the arrangement shown, current sources 30, 31 are both switched to capacitors 12, 13 by the first positive going transition of a pulse from oscillator 10 following a positive transition of a reference signal pulse at B. Source 31 is disconnected after a time determined by the period of the oscillator 10 output, and source 30 is disconnected after a time determined by the unstable period of monostable 24, a period equal to 1¢ times the nominal period of oscillator 10 output. Capacitors 12, 13 thus receive either a positive or negative current for a period depending on the magnitude and sense of the phase difference.

Abstract: 1,261,199. Recovering sulphur dioxide; sodium, lithium and beryllium, bisulphite and sulphite. WELLMAN POWER GAS Inc. 11 Nov., 1968 [9 Nov., 1967], No. 53218/68. Heading C1A. Sulphur dioxide is separated from a gas containing it, e.g. flue gas, by contacting the gas in a reaction zone, with an aqueous solution of sodium, lithium or beryllium sulphite at a temp., e.g. below 230‹ F., sufficient to react the SO 2  with the solution to give a bisulphite and below the temp. at which the bisulphite decomposes to the sulphite, so as to form an aqueous solution containing unreacted sulphite and the corresponding bisulphite, from which solution the sulphite content is removed by crystallization or, for example, by selective extraction, the bisulphite content of the solution being decomposed, simultaneously with or subsequent to the removal of the sulphite, under conditions of temp., pressure, and residence time such that gaseous SO 2 , water and the corresponding sulphite are produced, when the SO 2  so produced is separated and the sulphite so formed together with that initially separated is recycled to the SO 2  reaction step. Sodium sulphite is the preferred sulphite. In one embodiment, the sulphite/bisulphite solution produced in the first step is treated so that simultaneously it decomposes into SO 2  H 2 O and the corresponding sulphite, the water evaporates, and the sulphite crystallizes from the solution. The decomposition of the bisulphite is preferably performed at a temp. up to 300‹ F., e.g. at 230-300‹ F., under superatmospheric pressure. The crystallized sulphite may be separated from its mother liquor, dissolved in water and recycled to the SO 2  absorbing step. The mother liquor is decomposed to give SO 2  which is separated. The waste gas may contain 0À001 to 5 mole per cent sulphur dioxide and the absorbing liquor may contain 25 to 35% by wt. of dissolved solid, above 55% by weight of which is sulphite. The solution produced by the absorbing step may have a dissolved solids content of 25 to 35 wt. per cent and bisulphite constitutes 50-70% by wt. of its solids content. The Specification describes a particular form of gas/liquid contacting apparatus (Fig. 3, not shown).
