Title: Productions of haematite by cylcination of basic ferric sulphates
IPC: C01G49/02
Filed: 1976-05-13
Abstract: 1519082 Haematite MONASH UNIVERSITY 13 May 1976 [14 May 1975] 19836/76 Heading C1A Basic ferric sulphates are calcined to form hematite in at least two stages, the first stage being conducted at a relatively low temperature e.g. 250-600C to effect dehydration and the second stage being conducted at a higher temperature e.g. 600-1,000C to decompose the product of the first stage and form the hematite. The ferric sulphate may be jarosite, (Fe(OH) 2 ) 2 SO 4  or Fe(OH)SO 4 . The jarosite may be one produced by bacterial oxidation of ferrous iron in the presence of a monovalent sulphate and subsequent precipitation. SO 3  produced by calcination is preferably converted back into sulphuric acid. The haematite produced by the process may be used as a pigment, and when a red pigment is required the second stage heating is preferably carried out at 775-825C whilst heating to 850C produces a purple-red pigment. In an embodiment, doping agents may be added by including in the intermediate dehydrated product metal compounds e.g. barium carbonate or strontium carbonate which decompose to the corresponding metal oxides. In this embodiment the calcination is preferably carried out at 600-1400C with at least a portion in the range 1,000-1,400C. When a doped ferrite is to be produced, ammonium jarosite is preferably used as a starting material.

Title: Improvements in or relating to the preparation of permonosulphates
Inventor: MARSHALL JOHN GEOFFREY
IPC: C01B15/08
Filed: 1958-03-11
Abstract: Permonosulphates of sodium, potassium, lithium, caesium, ammonium, magnesium and zinc are prepared by reacting a bisulphate with hydrogen peroxide under conditions such that during the reaction, the hydrogen peroxide concentration is at least 60% by weight of the hydrogen peroxide and water present.  If evaporative conditions are employed the initial peroxide may be more dilute provided that the specified concentration is attained. Except for the case of magnesium and zinc where the bisulphates must be employed in solution, a dry mix method is preferred whereby a paste of the bisulphate and concentrated hydrogen peroxide is formed and heated.  According to Examples (1) potassium bisulphate was dissolved in 96% hydrogen peroxide, heated at 100 DEG C. and cooled to 20 DEG C.  Potassium permonosulphate was formed in solution.  Ammonium permonosulphate may be similarly produced.  (4) A paste made of potassium bisulphate and concentrated hydrogen peroxide was heated on a hot-plate to a temperature of at least 100 DEG C. thereby forming potassium permonosulphate.

Title: A percussive demolition tool with shock attenuating means
IPC: E21B1/38
Filed: 1963-05-21
Abstract: 973,139. Percussive drills. CHICAGO PNEUMATIC TOOL CO. May 21, 1963 [June 14, 1962], No. 20150/63. Heading B4C. A percussive tool such as a road breaker, comprises a casing 11 having a cylinder 13 in which a hammer piston 14 is adapted to reciprocate in order to pound, during a working stroke, the striking portion 35 of an anvil 15 which, in a low position, is seated on a shoulder 41 in the casing, and elastic yieldable means 19 in the easing for restricting the movement of the piston on its working stroke before the piston strikes the anvil while the latter is in its low position. The yieldable means 19 is in the form of two tubes 24, 25 bonded to a resilient material 26 such as neoprene, the ends of the outer tube 24 being clamped between the cylinder 13 and the front portion 12 of the casing 11. The anvil 35 is slidable in a sleeve 18 located within the tube 25 and provided with a flange normally held between one end of the latter tube and a shoulder 23 in the cylinder. In operation, if the drill bit 45 becomes stuck in the material 48 being drilled, the casing is lifted by handles 8 until further lift is prevented by an abutment 54 engaging with a flange 52 on the stem 45 of the bit as shown in Fig. 4. In this position the anvil drops on to the shoulder 39 so that the surface 42 of the upper striking portion 35 of the anvil is below the level of a chamfered surface 31 of the sleeve. If now the piston 35 is driven downwardly by pressurized fluid, instead of the piston striking directly the anvil and thereby transmitting the shock through the latter to the casing, the greater part of the force is taken up by the piston first striking the upper end of the sleeve and so distorting the resilient material 26 to absorb the energy.

Title: Improvements in or relating to furnaces intended for the utilisation of solid combustibles
Filed: 1945-08-07
Abstract: 610,522. furnaces. ADRIANOFF, A. Aug. 7, 1945, No. 20229. Convention date, Oct. 23, 1940. [Class 51(i)] A furnace of the type comprising two superposed combustion chambers which communicate freely with one another is characterized in that the principal furnace is formed by the upper chamber which has at its lowest part an inclined grate over which the fuel gravitates and through which air is supplied to the primary furnace, the residue of the products of combustion flowing freely into the lower furnace to complete their combustion. As shown in Fig- 2, the main furnace 1. comprises a gravity feed to a combustion chamber with sloping walls 2 and a sloping grate 5, the inclination being such that ash and small clinker gravitate to the auxiliary furnace above the grate 9. The main clinker mass accumulates in the region of the grate 5 and tuyers 6, and eventually occupies the space shown by the cross-hatching. The furnace is cleared by opening the door 11 and removing ash and small clinker from the grate 9, the clinker being then removed by a clinkering-iron through the door 10. This allows the incandescent fuel in the main furnace to fall on to the grate 9 and the main furnace is then re-charged. The air supply may be forced, and the combustion products of the auxiliary furnace pass through the main fuel bed. In a modification, the grate 5 is pivotally mounted so that the clinker may be dumped into the lower furnace preparatory to clearing the same.

Title: Dust content measuring apparatus
IPC: G01N21/53
Filed: 1975-05-14
Abstract: 1467529 Measuring dust photo-electrically CENTRE D'ETUDES ET DE RECHERCHES DE L'INDUSTRIE DES LIANTS HYDRAULIQUES 14 May 1975 [20 May 1974] 20430/75 Heading G1A Apparatus for measuring the dust content in a gas stream comprises: a source of electromagnetic radiation; a photo-detector near the source for measuring the radiation back-scattered by the dust; and means for directing a flow of air so as substantially to oppose the gas motion, thereby causing dust particles to accumulate in front of the apparatus.  Light, back-scattered from a laser beam 4 Fig. 2 directed down a flue (2), Fig. 1 (not shown), is detected by a photo-cell 8, e.g. a photo-multiplier. Cold air f entering a housing 10 through a pipe 12 cools the apparatus, keeping it free from dust, and emerges through an opening 11 in a direction opposed to the gas flow, causing a curtain of dust particles to be suspended in front of the apparatus. At low dust concentrations the laser beam may penetrate several metres into the gas; at higher concentrations any lack of penetration is offset by the increased accumulation of dust in front of the apparatus, so that the range of back-scattered light represents substantially linearly a wide range of dust concentrations. An interference filter 9 may be interposed in front of the detector, to protect it from stray radiation. A rotary chopper 5 co-operating with a synchronous electrical detector (not shown) may be arranged to modulate the laser beam. The apparatus 1 Fig. 6 may be positioned to extend through a wall of the flue at an acute angle, e.g. 30 degrees, to the gas flow, and may be made rotatable, Fig. 7, so as to scan a cross-section of the gas flow.

Title: Improvements in and relating to selective electric relays
IPC: H02H3/38
Filed: 1927-08-03
Abstract: 275,630. Meyer, Akt.-Ges., Dr. P. Aug. 6, 1926, [Convention date]. Automatic circuit-breakers; cut-out arrangements.-An impedance relay for use in electrical protective systems comprises a non-retarded voltage member or retarded current member and a power directional member, such members being arranged independently of one another both electrically and magnetically, but are adapted to co-operate with a contact mechanism operable by the independent action of both the current and voltage members when the flow of energy is in a predetermined direction. As shown in Fig. 1 the contacts e in the circuit-breaker tripping circuit are held apart against the action of a spring 16 by a manually reset latch 14 pivoted at 15. The latch 14 is tripped by a pin at the apex of a triangular jointed frame d under the control of cams 3, 7 operated by the voltage and current systems a, b. The cam 3 is raised or lowered in accordance with the voltage by a solenoid 1 with a core 2 from which the earn 3 is suspended. The cam 7 is mounted on a shaft carrying a pulley 6 over which passes a stretched wire adapted to be heated by the current. As the wire expands the cam is rotated and moves along the guided lower side of the frame d until it abuts against the cam 3. The lower side of the frame d is formed in two parts pressed apart by a spring so that further movement of the cam 7 compresses this spring and at the same time raises the apex of the frame to engage the latch 14. The tripping of the contacts is, however, prevented by the power-directional member c if the flow of power is toward the source, the end 13 of a guided rod operated thereby preventing the release movement of the latch. The rod 13 is pivoted to an arm 12 carried by an induction disc driven in a direction according to the direction of flow of power by voltage and current coils 9, 10. Alternative forms of the mechanical connection between the contact latch and the voltage and current systems are also described (Figs. 3 and 4, not shown), and also a modif.cation involving a thermal element in the form of a bimetallic strip compensated for the surrounding temperature (Fig. 5, not shown), and to prevent overloading of the strip it may receive its current safely through a saturated transformer. The characteristics of the relay may be varied by variation in the shape of the controlling cams or of the core of the voltage member. The impedance relay may be arranged to be inserted in the controlled circuit only after the operation of an associated overload relay.

Abstract: 806,081. Cleaning drums. WHITEHEAD CHEMICAL CO. (ENGINEERING) Ltd. Oct. 1, 1957 [July 3, 1956], No. 20531/56. Class 138(1). A drum cleaning machine supports and rotates an open ended drum with its axis horizontal upon driven rollers, and a brush rotating in the opposite direction to that of the drum and in contact with its internal surface is reciprocated relative to the drum whilst cleaning liquid is continuously sprayed against the surface being cleaned. The machine has three sets of rollers 17, 18 and 21, the latter of which is movable to allow the drum to be placed in position, which prevent radial displacement of the drum 24, the pair of rollers 17 being rotated slowly (about 20 r.p.m.) by the electric motor 35 which drives shaft 16, belt 56 and pulley 15. The rollers 17, 18 and 21 are mounted upon axles 14, 19 and 20 attached to vertical corner posts 13 of carriage 12, which can be moved along guide rails 11 by means of the screwed rod 41 and hand wheel 43 until the brushes 36 bear against the internal surface of the drum. Longitudinal movement of the drum is prevented by closing the gate 61 which is hinged at 62 and carries casters 60 which are pressed against the base of the drum by screws 59; closure of the gate also closes master switch 64 which supplies power to the machine. A carriage 28, mounted on guide rails 27, carries a motordriven shaft 34 fitted with brushes 36 and 37 that are rapidly rotated (about 3000 r.p.m.), and also reciprocated relative to the drum by the motor-driven camshaft 31 connected to the carriage 28. The base of the drum 24 is cleaned by brush 37, which is moved by hand into contact with the base by disengaging the clutch 40 and operating the camshaft 30 by handwheel 55. By rotating handwheel 43, the drum may be moved in a direction at right-angles to its axis, allowing brush 37 to traverse the base of the drum and the cleaning liquid, supplied as a spray from nozzles 44, escapes from the drum into a series of settling tanks, that may contain filters, and is recirculated by an electric pump.
