IPC: F04D1/06
Abstract: 113,721. Milne, S. May 24, 1917. Radial flow (unbladed) type; blades, vanes, nozzles, and the like; treating wearing- surfaces; leakage-preventing devices. - In turbines having inlets on both sides of the rotors, these are formed with Bat parallel sides and of corresponding width to the coacting peripheries of the interposed diffusers. Fig. 1 shows the application to a multi-stage pump having impellers a mounted on a shaft b with renewable spacing- sleeves f. The fluid is drawn from the inlet c to eyes a<1>, a<2> in the first impeller, and is discharged at a' into collecting passages h in the diffuser e. The passages h open axially into an annular chamber o from which the fluid passes in part directly to the eyes on one side of the next impeller, and in part through channels h' leading to the eyes on the opposite side of this impeller, this cycle of operations being continued to the main outlet d. In modifications, each section of the casing e is integral with the division plate of the next unit. The various passages may be lined with glass or enamel, and, to prevent leakage the rubbing surfaces of the impellers and diffusers may be formed with grooves; or a grooved ring such as l<1>, Fig. 9, may be screwed or bolted to the diffuser.

Title: A process for heat-treating a material
IPC: C04B7/43
Filed: 1966-03-15
Abstract: A process for heat-treating a material, particularly applicable to the manufacture of cement clinker, comprises first heating the material at a temperature below 1000 DEG  C. in a non-rotary furnace in which low grade solid fuel is burnt in the suspended state to provide at least part of the thermal energy requirement, and thereafter heating the material at above 1000 DEG  C. in a rotary furnace.  The non-rotary furnace is preferably a fluidized bed.  The heat content of the gaseous and/or solid products of the rotary furnace may be exchanged with the starting material prior to treatment in the rotary furnace.  The low grade solid fuel may be of coarser grain size than the starting material in which case the coarse grain slag is drawn off separately, or the low grade solid fuel may be finely divided and the finely divided slag drawn off with the flue gases and separated therefrom by means of a cyclone.  In the manufacture of cement clinker the deacidification of the CaCO3 component may be at least partially effected in the non-rotary furnace and at least 30% of the energy required therefor obtained from the raw materials, the remainder of the energy requirement for deacidification being supplied by the fuel fed to the non-rotary furnace.  Preferably, a pre-heater is disposed up-stream of the non-rotary furnace to which the meal of ground limestone is fed.  The product of the non-rotary furnace may be adjusted to have a standard lime value of 95\sB5 before being fed to the rotary furnace.

IPC: C07C51/41
Filed: 1928-04-18
Abstract: 316,159. Dreyfus, H. April 18, 1928. Hydroxy aliphatic carboxylic acids are obtained by catalytic hydrogenation of acid salts of aliphatic polycarboxylic acids, and liberating the free acids from the resulting salts in any suitable manner. The reaction may be carried out at atmospheric or under increased pressure, using pure hydrogen, or gases containing it, e.g. water gas, town gas, producer gas &c. Any suitable hydrogenation catalyst, e.g. nickel, copper, platinum, palladium, cobalt or iron, and a solvent or inert diluent for the salt treated may be used. In an example, potassium hydrogen oxalate is treated in an autoclave to obtain potassium glycollate. Other salts of oxalic acid and those of malonic acid, succinic acid &c. may be treated. The acids thus obtained may be etherified or esterified.

Title: Improvements in Weft Spool Changers for Weaving Looms.
Inventor: KOECHLIN ALBERT GEORG
IPC: D03D45/34
Filed: 1919-05-09
Abstract: 127,245. Koechlin, A. G. May 18, 1918, [Convention date]. Shuttles, changing bobbins in, automatically.- In a spool-changing loom of the kind in which a pusher or transferrer moves with the lay, the pusher, during its travel, remains in co-operative relationship with, and-slides along, an arm adapted to depress it to effect the change of spool, and mechanism of the kind independent of the driving- mechanism of the lay is provided for operating the arm when the weft fails, and is so arranged that the pusher may be depressed at any time from before the lay is at front centre to the moment when the throw of the shuttle begins. When the weft fails, the weft-fork 5 is engaged by the weft hammer 7, and the fork-carrier 2 acts through a lever 8 to turn a cross-shaft 13. A lever 14<a> on this shaft moves a sliding rod 14 carrying a rack gearing with a pinion 15 provided with a crankpin connected by an arm 16 to a lever 17. A fork on the upper arm of this lever moves a clutch part 19 along a pin 21 and clutches it to an arm 25 extending forwards over an adjustable cross-head 26 on the pusher 27, which is slidably mounted on and moves with the lay 28. At the same time, an adjustable roller 23 on an arm 22 carried by the part 19 is moved into position on a disk 24 to be acted upon by a cam 31 on the disk, so that the pusher is depressed by the arm 25 against the action of springs and transfers a fresh spool from a spool-carrier into the shuttle. The cam-disk 24 can be adjusted to effect the change of spool at the desired movement within the limits mentioned above. Instead of using the clutch device, the cam-disk 24 may be moved to bring it into operative relationship with the cam 25 or with a forked treadle arm engaging the lower end of a rod connected to the pusher, slidably carried by the lay, and normally held raised by springs. A pawl 6 is mounted on the weft-fork carrier 2 and engages a slidable rack 3, which it moves forwards against the action of a spring when the carrier is moved on failure of weft. A detent 9 on a fixed pivot engages the rack and holds it in its displaced position until the weft hammer again moves forwards. If weft is presented to the fork, a tappet 10 on the weft hammer strikes tails 6<a>, 9<a> of the pawls 6, 9, and releases the rack, which returns to its normal position.
