Title: Electroacoustic transducer
IPC: H04R1/00
Filed: 1973-06-01
Abstract: 1382927 Electroacoustic transducers INTERNATIONAL BUSINESS MACHINES CORP 1 June 1973 [30 June 1972] 26209/73 Heading H4J An electroacoustic transducer for decoding a digital signal received serially by code word and converting it to sound comprises a sound generating element and a plurality of driving elements therefor. Each driving element can be energized independently of the others by an electrical signal whose magnitudes is determined for each code word by the value of the digital signal in a respective bit position thereof. A cantilevered piezoelectric bender plate (Fig. 1) is controlled by coded PCM signals and directly converts them to sound waves. The plate consists of two layers of ceramic material. At least the upper one has piezoelectric properties. A common electrode is located between the two layers. Six rectangular bit electrodes with different areas are mounted side-by-side as driving electrodes and each is connected to a respective electric line corresponding to a different bit position of the coded PCM signals. The deflections caused by the bit electrodes when energized with equal signals have the same ratio as the positional weights in a binary code, i.e. 1 : 2 : 4 : 8 : 16 : 32. If several bit electrodes are energized simultaneously, the deflections are added together. Binary signals with any other positional weights can be used if the electrodes are suitably dimensioned, as can digital signals other than binary signals. Instead of ceramic piezoelectric layers, monocrystalline layers can be used. A relatively broad and short bender plate (Fig. 3, not shown) may be used with four electrodes (1<SP>1</SP> to 4<SP>1</SP>) mounted in pairs across the width of the plate. An alternative device for binary signals with a sign bit is similar to that of Fig. 1 but the bender plate consists of two oppositely polarized ceramic or crystalline piezoelectric layers with a common electrode mounted in between (Fig. 4, not shown). Two similar sets of bit electrodes are mounted on the surfaces of the bender plate. In another arrangement a circular plate of piezoelectric material consists of two layers with a common electrode in between. Bit electrodes (1c, 2c, 3c ... 6c), Fig. 5 (not shown), have the form of concentric rings. The circular plate acts as the diaphragm. It may form part of an earphone capsule (Fig. 6, not shown).  Another arrangement uses an electrostatic transducer (Fig. 7, not shown) comprising an elastically suspended metal diaphragm spaced from bit electrodes in the form of concentric rings. An electromagnetic transducer (not shown) has the coil of an electromagnet subdivided into a plurality of windings. The number of turns for any one winding is such that the effected deflection of the diaphragm is proportional to the positional weight of the respective code bit.

Title: Improved process of producing anhydrous substances
IPC: C01D1/42
Filed: 1936-09-30
Abstract: Anhydrous substances are obtained from deliquescent salts or hydroxides or salts capable of crystallizing with water of crystallization, such as caustic soda or potash, zinc chloride, magnesium chloride or sulphate, by evaporation of the aqueous solution of the substance in the presence of an inert diluent immiscible with water, such as a hydrocarbon or a hydrocarbon derivative.  Diluents specified comprise kerosene, naphthalene, dichlorbenzenes, dichlortoluenes or coal tar distillates of boiling point above 160 DEG  C.  The boiling point of the diluent preferably lies between 150 and 300 DEG  C.  In an example, 180 parts of a caustic soda solution containing ten per cent caustic soda by weight are mixed with 300 parts of kerosene and the mixture distilled. Complete removal of water is reached at a temperature of 200--225 DEG C., leaving about 174 parts of the kerosene in the still.  The latter is decanted off leaving anhydrous granular caustic soda.

Title: Method of producing ammonia-phosphorus pentoxide reaction products
IPC: C05B17/00
Filed: 1952-10-23
Abstract: <PICT:0729243/III/1> An ammonia-phosphorus pentoxide reaction product is produced by treating gaseous phosphorus pentoxide with substantially anhydrous gaseous ammonia at a temperature of 240 DEG C. to 725 DEG  C. and then rapidly cooling the product to a temperature below 200 DEG  C.  The product may be calcined by maintaining in an atmosphere of ammonia at 20 DEG  C. to 300 DEG  C. for one to three hours.  The reaction may be carried out at a temperature of 240 DEG  C. to 500 DEG  C., preferably 325 DEG  C. to 350 DEG  C. employing a molar ratio of ammonia to phosphorus pentoxide of 2.2 : 1 to 3.2 : 1, in which case a highly soluble product is obtained on calcining, preferably at 100 DEG  C.; or at a temperature of 500 DEG  C. to 725 DEG  C., preferably 675 DEG  C. to 700 DEG  C., employing a similar molar ratio, in which case the calcined product is moderately to substantially insoluble, the minimum solubility being obtained by calcining at 250 DEG  C. to 300 DEG  C.  If the ammonia to phosphorus pentoxide intermediate is produced at 500 DEG  C. to 600 DEG  C., the calcination is preferably carried out below 120 DEG  C., or by heating to 175 DEG  C. to 225 DEG  C. for 10 to 20 minutes, screening the cooled product and calcining at 250 DEG  C. for one hour.  If the reaction takes place at 600 DEG  C. to 725 DEG  C., calcining at 250 DEG  C. is preferred. A product having useful water-resistant properties or for use as a flame-proofing agent or speciality fertilizer is produced by reaction at 675 DEG  C. to 700 DEG  C. and calcined for one hour at 100 DEG C.  Calcining of either the high or low solubility form in the presence of an atmosphere of 100 per cent. by volume ammonia is preferred, though air, nitrogen or another inert gas may be present. A number of examples is given, in which the apparatus of Fig. 1 is used.  In this apparatus molten phosphorus is introduced by line 2, whilst an excess of air is injected tangentially through line 1.  The products pass through tube 5 and come into an insulated zone equipped with electrical windings to heat said products to a suitable temperature indicated by means of thermo-couples in wells 9 and 11. Ammonia is introduced through pipe 13 and a pipe in the opposite side (not shown).  The complex passes through the air, or otherwise cooled zone 14 where it is cooled to a free flowing white powder which passes into the collecting chamber 15 and is separated from the gaseous products by means of filter 16.  The sojourn time from the introduction of ammonia to removal of reaction product is 3 to 5 seconds or less.

Abstract: 645,737. Fish-cutting machines. ARENCO AKTIEBOLAG. Oct. 14, 1948, No. 26795. Convention date, Oct. 17, 1947. [Class 28(ii)] Fish-cutting machines having a pair of disc cutters 9a, 10a, rotating in opposite directions and coacting to cut the fish transversely have means for rotating one of the cutters at a peripheral velocity different from that of the other cutter, either by rotating discs of different diameters at the same speed, or driving discs of equal diameter at unequal speeds. The slower disc 9a has on its periphery transverse flutes of teeth inclined rearwardly relative to the rotary direction. The fish are fed from a conveyer 3 into pockets 5 on a rotatable drum 4 past a curved guard plate 6 with a tapered end 18 into pockets 8 of a rotatable drum 7 with recesses 19 for the slower toothed cutting discs 9a, 9b rotating with the drum. The fish are thus delivered transversely against the faster rotary discs 10a, 10b on a rotary shaft 20 for cutting off the head and tail. The drum 8 is in three parts and the discs 9a, 9b are secured to two of these parts. One end part of the drum is adjustable along the drum axis 16 for fish of different length and the pockets 8 on the drum are in two telescoped parts. The space between the disc cutters 10a, 10b on the shaft 20 is also adjustable and the edges of these cutters enter the recesses 19 to engage the discs 9a, 9b yieldingly under the influence of springs 21 on the shaft 20, which is driven by gear wheels 25 from the shaft 16. A pair of fingers 30 are turnably mounted on a spindle 29 and actuated by springs 31 thereon to hold the fish against the cutters during cutting. A jet of water from a nozzle 17 displaces the fish longitudinally in each pocket 5.
