Title: Improvements in or relating to chain grate stokers
Inventor: BANES WILLIAM
IPC: F23K3/08
Filed: 1953-06-18
Abstract: 743,435. Chain grate stokers. DANKS & CO. (OLDBURY), Ltd., E. June 18, 1954 [June 18, 1953], No. 16831/53. Class 51 (1). In a chain grate stoker having rows of grate links 9 assembled on transverse link rods 10 and including an -air box having side plates 1 on opposite sides of the lower run 7 of the grate, the side plates 1 are extended upwardly at 13 so as to limit, along the upper run 6 of the grate, axial movement of the rods 10 and thus maintain them in operative position relative to the links. The driving shaft 11 at the front end of the grate is mounted in bearings 16 which are adjustable in slots 19 by means of nuts 22 provided on the outer ends of tensioning screws 20. To provide for the ready removal of a link rod 10, the extension 13 of each side plate 1 is formed above the slot 19 with an aperture 26 adjacent the lower end of which a plate 27 is welded to the outer surface of the side plate; a guide plate 28 is removably secured by bolts 29 to the plate 27 and has its inner face shaped, as shown in Fig. 4, with two parallel portions 31 and an intermediate portion 32 inclined from front to rear. When removal of a rod 10 is required, the rod is brought to a position between the guide plates 28 which are then removed and after reducing the tension of the grate by slackening the nuts 22 a tool is passed through one of the apertures 26 to push the link rod through the other aperture 26.

Abstract: 139,097. Taylor, J. E. July 5, 1919. No Patent granted (Sealing fee not paid). Pocket igniters, frictional.-The cap, which encloses the wick or tinder of a pyrophoric pocket igniter when not in use, is provided with a rack, pawl, or its equivalent for automatically rotating the etriking-wheel as the cap is removed. In one form, a rack O<x>, Fig. 3, is pivoted to the cap n and is urged by a spring p into engagement with teeth on the striking-wheel g, which is journaled in a fork on the flint tube d, a closing cap being secured by a bayonet-joint to the lower end of the tube d. When replacing the cap n, it is turned slightly from its normal position so that the rack shall be disengaged from the wheel until the cap n is in position, the cap being retained in the correct position when withdrawing or replacing the cap n by a pin u or projection on the body of the igniter engaging a slot, opening t, or depression in the cap n. In a modification, a fixed rack on the cap n operates the wheel g through a loose pinion and a pawl,

Title: Improvements in or relating to processes for the preparation of an aromatic coffee extract
IPC: A23F5/48
Filed: 1948-06-25
Abstract: In a process of the kind in which roasted coffee is extracted with ethyl alcohol, and then with an aqueous fluid, the products of the two extractions being combined, the alcoholic extract is cooled at least once to precipitate all or practically all the fatty substances, which are then removed.  The alcoholic extraction may be performed in a battery of extractors in series, at any temperature from 60 DEG C to approaching 0 DEG C.  If necessary, the extract may be concentrated, preferably in vacuo.  The fats (together with phytosterins and bitter substances) are precipitated by cooling to a temperature of at least -10 DEG C, and are separated, as by decanting, filtering or centrifuging.  The concentration, cooling and separating processes may be repeated. The alcoholic extract is now combined with the dry residue of an extraction with hot water or steam.  The alcohol (and constituents at least as volatile as alcohol) are removed by evaporation (in vacuo or at ordinary pressure), the mixture being continuously stirred meanwhile.  The Specification as open to inspection under Sect. 91 comprises also a reference to the enriching of the extract with aromatic constituents by bringing it into contact with roasted coffee less and less drained of these constituents.  The combination of the alcoholic and aqueous extracts may be carried out gradually and simultaneously with the evaporation of the alcohol.  This subject-matter does not appear in the Specification as accepted.

[Also in Group XXX] A piston 15 in a cylinder 14 having alternate supply and exhaust ducts 3, 4 is actuated by compressed, air from a supply duct 1 traversing one or other of passages 17 to one or other side of a double piston valve 9, the duct 3 supplying air during the forward stroke when air in front of the piston 15 is exhausted through the duct 4 and a continuously open exhaust duct 5 between the pistons 9, and the return stroke being effected on suddenly reducing the pressure in a duct 2 connected by branch ducts 19 to both ends of the valve chamber 10 and to the supply duct 1 through one of the passages 17 and a flutter valve, when an apertured seat 13 is vacated by a ball &c. 11; said pressure reduction causing the ball 11 to move from a seat 12 to the seat 13 so as to connect the supply duct 1 to the other side of the double piston 9. A further forward stroke of the piston 15 is initiated by reducing the pressure in the duct 2 e.g. by means of a relief valve (not shown).

Filed: 1916-12-02
Abstract: 103,113. Akt.-Ges. Brown, Boveri, et Cie. Jan. 3, 1916, [Convention date]. Addition to 14498/15. Automatic circuit-breakers. - In the construction of automatic circuit - breaker with time-limit device described in the parent Specification, the pawl 7, which is engaged with the time mechanism, is coupled directly to the armature 3 by a strong spring 6, which yields only in the case of particularly high excess currents, thereby instantaneously effecting the release of the switch. According to the present invention, the pawl may be locked at will to the armature to render the instantaneous release arrangement inoperative. As shown, the armature is formed with a notch 22, 23 in which is inserted a loose plate 21 having an eye in which the end of the spring is engaged. In the position A, the plate is held against the side 22 of the notch, and the spring acts as described in the parent Specification; when the plate is turned, by hand, into position B to bear against the other side of the notch, it engages the projection 24 of the pawl, which is thereby locked to the armature.

When a plate 26 pivoted to the lever 22 is released by a rod 30 connected to a bale measuring wheel the plate is pivoted by a spring (32) so that a pin thereon moves into the path of a cam (35) on the drive wheel 10. The cam pushes the plate and thus pivots the lever 22 to allow the spring plate to engage the drive wheel. Resetting of the rod 30 returns lever 22 to its normal position so that after one revolution of the spring plate it is declutched by a roller 20 thereon riding up a ramp on the lever. The lever has a ramp on its other side so that the spring plate can be declutched if the drive wheel is driven in the reverse direction to unjam the baler.

Filed: 1959-05-26
Abstract: Zinc is recovered from zinciferous mineral sulphides by a process which comprises the steps of dispersing the sulphide in the form of particles in an aqueous acidic sulphate solution to form a slurry, adding sulphuric acid to the slurry to provide sufficient free sulphuric acid to combine with the zinc content of the sulphide as sulphate, reacting the slurry with a free-oxygen containing gas at a temperature below the melting point of sulphur, preferably between 90 DEG C. and 112 DEG C., and under an oxygen partial pressure of above 0,3 atmospheres continuing the reacting at a pH below 2,5 to extract the zinc from the sulphide to form a solution of zinc sulphate, with concurrent oxidation of sulphide sulphur to elemental sulphur, separating elemental sulphur and undissolved residue from the zinc sulphate solution, and recovering zinc from the solution as the metal, for example by electrolysis.  The elemental sulphur may also be separated, for example by melting and filtering, and the remaining sulphides returned to the oxidation treatment.  Alternatively the slurry may be heated to above the melting point of sulphur after the oxidation to form molten sulphur globules, cooled to solidify the globules which are then separated from the slurry, and the zinc sulphate solution then separated from the undissolved residue.
