Title: Improvements in and relating to the combustion of materials of very low calorific power
Inventor: QUINTIN ALBERT ANDRE JOSEPH
IPC: G21C3/06
Filed: 1958-03-24
Abstract: 858,462. Furnaces; ash pits. COMPAGNIE DES METAUX D'OVERPELT-LOMMEL ET DE CORPHALIE. March 24, 1958, No. 9303/58. Class 51 (1). Pulverized carbonaceous shale of very low calorific value is burnt in a fluidized bed 3, the combustion air having absorbed most of the sensible heat of the ashes. Air under pressure passes through inclined perforated plates 9, 10, 11 independently or in series, being heated by its passage through the beds of burnt shale which are thus moved along the plates 9, 10, 11 to the discharge hopper 18 and screw 19. The hot air is collected in an annular space 20 surrounding the plate 9, 10, 11 and maintains the fluidity of the combustion bed 3. Ashes swept off by the gaseous combustion products are collected in a cyclone 6 and returned by a screw feed 22 to upper ash plate 9.

Abstract: 827,127. Grinding. PITTSBURGH PLATE GLASS CO. March 26, 1958 [June 3, 1957], No. 9683/58. Class 60. Apparatus for abrading the curved longitudinal edges of flat glass sheets G, Fig. 3, such as car windscreens, comprises a horizontal conveyer 13 and at least one track 26 extending transversely of the conveyer and having a pair of carriages 28 mounted for location in predetermined positions, each carriage having pivoted thereto a power-driven system consisting of driving and driven pulleys 48, 52 and an abrasive belt 50, the systems being so balanced as to cause the abrasive belts to pivot slowly into engagement with opposed longitudinal edges of the glass and having freely rotatable guide rolls 66 located intermediate their pulleys to limit the maximum spacing of the belts at the plane of the conveyer to the width of the increment of glass passing therethrough. In the embodiment shown, two tracks 26, Fig. 2, are mounted above the conveyer which comprises driven conveyer rolls 13 and pinch rolls 14 mounted above selected conveyer rolls, the pinch rolls being vertically adjustable in housings 18. The carriages 28 are movable along the tracks on rollers 30, Fig. 3, and are clampable in predetermined positions by means of hand levers 32. Each pulley system is carried by a bracket 94 pivotted at 38 to a carriage and consists of a pulley 48 driven by a motor 44, a pulley 52, and an abrasive belt 50 ; the tension in the belt is adjusted by a screw-andnut device arranged to vary the compression of a spring which is disposed in a sleeve 82 secured to the bracket 94 and axially urges a rod 80 carrying the pulley 52 away from the bracket 94 and pulley 48. The pulley-systems are so balanced by counterweights 58 as to pivot slowly to bring the abrasive belts gently into engagement with the edges of the glass sheet ; stop bars 60 provide limiting positions of the systems to prevent the belts from engaging each other when a glass sheet is not between them. The depth of engagement of the belts into the glass is limited to prevent excess abrading by the rollers 66 which are mounted at the sides of the belts with their peripheries in tangential planes common to the pairs of pulleys. Pairs of glass sheets are fed along the conveyer in parallel paths to the pairs of carriages which are in staggered arrangement to reduce the overall width of the conveyer, each pair of sheets, after their edges have been abraded, being jointed by a layer of thermosetting resin to form a laminated windscreen. In other embodiments, the pulley-systems may be pivotted in cantilever fashion from beneath the conveyer, and the motors 44, driving the pulleys, repositioned to require counterweights to provide turning moments in excess of those provided by the motors.

Patent GB-805517-A (GB)
Title: Improvements in or relating to a process for the preparation of phosphoric acid
IPC: C01B25/22
Filed: 1957-03-25
Abstract: Calcium triphosphate is dissolved in aqueous hydrochloric acid, and the phosphoric acid produced is extracted by means of an organic solvent which has a limited miscibility with water. Organic solvents specified are alcohols, e.g. n-butanyl and iso-amyl alcohol, and ketones.  Extraction may be effected continuously in co- or counter-current flow, or one or more times in a batch process.  An excess of hydrochloric acid is preferably employed in the dissolution step; if less is employed, the organic solvent extract may be treated with aqueous hydrochloric acid so as to extract calcium therefrom. Phosphoric acid may be recovered from the organic solvent extract as an aqueous solution by the addition of an organic solvent miscible with the first solvent but immiscible with aqueous phosphoric acid, e.g. benzene.  Hydrogen chloride may be removed from the aqueous phosphoric acid by distillation or stripping with air at a temperature of 80-90 DEG  C. The two organic solvents may be separated by fractional distillation and separately recycled.  The phosphoric acid may alternatively be recovered by directly subjecting the extract to distillation or stripping so as to remove solvent and hydrogen chloride.  Tricalcium phosphate may be subjected to treatment in the form of phosphate rock which may be precalcined. Air may be passed through a hydrochloric acid solution of phosphate rock before organic solvent extraction in order to remove hydrogen fluoride.

IPC: B41J2/175
Filed: 1998-07-13
Abstract: An ink containment and dispensing device for an ink-jet printer is provided with a main reservoir in the form of a flexible pouch, which is typically maintained at ambient pressure. The main reservoir is coupled to a variable volume chamber via a one-way valve which allows the flow of ink from the reservoir to the chamber and prevents the flow of ink from the chamber to the reservoir. The chamber is coupled to a fluid outlet, which is normally closed to prevent the flow of outward ink. However, when the ink supply is installed in a printer, the fluid outlet establishes a fluid connection between the chamber and the printer. The chamber is part of a pump provided with the ink supply that can be actuated to supply ink from the reservoir to the printer. The pump has a linearly acting pumping member and a flexible diaphragm that overlies the pumping member, the diaphragm being impervious to the transmission of oxygen and moisture therethrough to prevent degradation of the ink within the chamber. <IMAGE>
