IPC: F26B21/00
Filed: 1924-12-09
Abstract: 245,263. Elkington, V. Dec. 9, 1924. Air, controlling temperature, humidity, and direction of flow of.-A method of drying hops &c. consists in distributing dry heated air over the upper surface of the hops and heated air containing a regulable quantity of moisture to the under surface, the temperature of the air beneath the hops being gradually raised to that of 'the air above. As shown in Fig. 1, the hops 3 are supported upon a hair and hot dry air is forced by a fan 5 through an air-heating surface 4, pipe 6, and rotary hub 8 to the air-distributing arms 7, while hot air moistened by steam jets 15 is supplied through a pipe 9 to the under surface of the hops. In a modification, the airdistributing arms beneath the hops are dispensed with and an air-heating furnace is placed in the lower part of the chamber in which the hops are supported, the air being distributed by a fan. In another arrangement, the air is supplied to the upper and lower sides of the hops from a single heater 23, Fig. 3, through a pipe 6 and a duct 24. In another modification, the pipe passes through the duct within the chamber.

Title: Machine for manufacturing wire fabric
IPC: B21F27/00
Filed: 1955-10-20
Abstract: 793,387. Coiling; matting wire fabric. BLASHILL, A. E. Oct. 20, 1955 [Nov. 3, 1954], No. 29973/55. Class 83 (4). A machine for making wire fabric having means for forming the fabric in a series of successive meshes, means for releasing the fabric intermittently from the said forming means, an intermittently driven sprocket shaft over which the fabric passes and means including a wind-up shaft to which the fabric is delivered by the sprocket shaft, is characterized by a take-up assembly over which the fabric travels after leaving the said releasing means, and before it reaches the said sprocket shaft, said take-up assembly including counterweighted rolls over which the fabric passes in succession. Double wire helices formed by a rotary former blade and a giraffe are fed into a tube 16 and there interlaced with previously formed helices to form a wire fabric 18. The tube 16 has a hinged section 221 normally held up by spring pads 30 but allowed to drop down, for access to the inside of the tube, by operation of interlinked handles 26, 261 pivotally connected to rocker arms 34 keyed on a shaft 36. The fabric 18 is released intermittently from the tube 16 by rocking a shaft 76 carrying front and rear hooked fabricengaging fingers 74 and passes over a roll 50, under a roll 52 and over an intermittently rotated sprocket shaft 42 to a shaft 40 on which the fabric is wound. The roll 50 is carried at the end of a pair of arms 54 pivoted at 56 and connected by links 60 to arms 62 carrying the roll 52 and mounted on a rock-shaft 64. The shaft 64 has an arm 72 counterweighted at 66 so that roll 52 is urged downwards and roll 50 upwards. Specification 510,948 is referred to.
Patent GB-628990-A (GB)
Title: Improvements in or relating to internal combustion operated devices of the free-piston type
IPC: B25D9/10
Filed: 1946-10-08
Abstract: 628,990. Reciprocating magnetos. BARD, F. N. Oct. 8, 1946, No. 29991. [Class 35] [Also in Group XXVII] In an internal-combustion free-piston percussive-device (see Group XXVII), the generation of an ignition spark is effected by a reciprocating magneto operated by a piston 11, Fig. 2. Mounted upon an armature shaft 29 is a core 27 which has a primary and secondary winding formed upon it. When the armature is moved from the influence of the right-hand poles 26a, 26b of a permanent-magnet assembly 26, to the left-hand pole-pair 26c, 26d, the primary winding experiences a rapid reversal of flux. At the same time the outer end of the armature shaft 29 impinges upon a steel strip 33 and so forces apart two contacts, one of which is fixed to the end of the steel strip 33, thereby breaking the primary circuit and causing a high voltage (about 10,000 volts) to be induced in the secondary from where it is led by a cable 36 to a sparking plug. In a modification, a shuttle armature 127, Fig. 10, is made to oscillate through about 20 degrees on either side of a position slightly counter-clockwise of the neutral position shown, between a pair of poles 126a, 126b. It is stated that a stud member connected to the armature shaft actuates a contact breaker. In a further modification, the magneto, which is mounted above the piston 161, Fig. 14, is of the reciprocating type. The magnetic circuit through either of the poles 176a, 176b and the armature case 177 is completed through the machine body. The upper contact 190a of a contact breaker is fixed to and therefore moves with the armature core 177 whilst the lower contact 190b is spring- loaded and permitted a small vertical movement until a nut 204a abuts the underface of a block 206.

Title: Improvements in or relating to the tail surfaces of aircraft
IPC: B64C5/06
Filed: 1927-11-09
Abstract: 311,348. Wright, M. E. A. Nov. 9, 1927. Steering, balancing, and regulating altitude.- Tail surfaces of aircraft, particularly surfaces of substantially symmetrical aerofoil section, have thin planes mounted at each side of their leaving edges and adapted to be moved from a normal position in contact with the surfaces automatically, or positively by connection with a hinged portion of a tail surface on the controls therefor, in order to form " slots " at either side of the surface. In the arrangement shown in Fig. 2, the thin planes h, j are carried by arms k, m pivoted to a vertical or horizontal tail surface n, one or other of the planes being moved by suction on one side or other of the leading edge of the surface n. In the arrangement shown in Fig. 3, levers carrying the thin planes are operated by a cam r which is turned about its shaft s by the controls of the hinged portion o of the tail surface. In a modification of this arrangement, Fig. 5, not shown, the controls are connected directly to a lever fixed on the shaft which also carries a cam connected by a link to an arm on the hinged tail portion o. The forward end of the link in engagement with the cam is also connected by a link to the fixed tail surface, and by adjustment of the point of connection of the second link to the tail surface, a zero-setting control of tail portion o relatively to the thin planes is obtainable. Also, the cams may be designed so that the planes h, j may be actuated in advance of the tail portion o, or vice-versa. In the arrangement shown in Fig. 4, the levers p, carrying the thin planes carry blocks y, z, slidable in an arcuate guide x connected by links v, w to the control lever n of the tail portion c, the guide being also connected to the portion o by a link 11 which is pivoted at its rear end coaxially with the portion o and is controlled by a cam 13 the shaft 14 of which is rotated by a pulley 16 and cable 15 connected to a lever 17 on the portion o. When the tail portion o is moved by the controls t, the cam 13 moves the link 11 to one side or the other so that movement of the guide x by the links v, w moves only one of the planes h, j. The rate of formation of the "slots " varies with the extent of movement of the portion o. A zero-setting control may be incorporated by making the cam 14 angularly adjustable with respect to the pulley 16.
Patent GB-750104-A (GB)
Title: Improvements in or relating to purifying water-insoluble solids
IPC: B01J47/10
Filed: 1953-10-30
Abstract: <PICT:0750104/III/1> Ionic impurities are removed from water-insoluble solid particles by mixing the solids with ion-exchange particles in a mixing zone 7 through which water flows upwardly into a disengaging zone 9 where the velocity of the water is reduced so that the purified solid particles move upwards and are removed at 23 and the ion exchange particles move downwards and are removed from the bottom of the mixing zone.  The ion exchange solids should have a larger particle size or density than the other solids; separation may be assisted by providing a screen filter 21.  The solid particles to be purified are mixed with water at 15 and enter the mixing zone through line 19.  The ion exchange solids enter through line 51 and well 53 and after passage through the mixing zone leave through stripping zone 5, settling zone 3, and line 55; after treatment with regeneration liquid introduced at 57, they pass through filter 59 and are recycled to line 51.  The slurry of purified solid particles in line 23 passes to cyclone separator 27, filter 31, and drier 35; water from separator 27 may be heated at 43 and returned to the mixing vessel 15 or to stripping zone 5; water from filter 31 passes to settling zone 3. The mixing zone may operate at a temperature of 32 DEG -212 DEG F.  A cation exchange resin may be used for the removal of sodium ions from gels of silica or alumina, or mixed gels of silica, alumina, and magnesia which are to be employed as cracking catalysts.  An anion exchange resin may be used for the removal of sulphate ions from zinc-alumina spinel which is to be mixed with molybdena to provide a hydroforming catalyst; the anion exchange material may contain hydroxide, acetate or nitrate ions.  Reference is also made to the treatment of oxide gels of magnesium zinc, chromium, zirconium, titanium, iron, beryllium, copper, cobalt, and nickel, and clays, for example acid-treated clay catalysts.
