Title: Improvements in and relating to a revolving tine harrow and cultivator for use in the cultivation of land for growing crops of cereals and roots and general farm produce
IPC: A01B21/04
Filed: 1930-04-30
Abstract: 354,186. Implements for working land. LEES, A., High Street, and STONE, C. T., Moor Farm, both in Fairford, Gloucestershire. April 30, 1930, No. 13265. [Class 6 (i).] A rotary harrow or cultivator comprises a wheelsupported frame carrying rows of rotatably-mounted tines and provided with means for adjusting the frame vertically, and with manually-operated lever mechanism for adjusting the rows of tines relatively to one another. The tines 4, 4<*> are mounted in shafts 5, 6 extending across the frame 1 and supported in self-aligning ball bearings in depending brackets 7, 8. The brackets 8 are movable along the frame bars simultaneously or independently by either one or two levers 21 and links 22. By this means the shaft 6 may be adjusted parallel to the shaft 5 or at an angle to it. Both shafts may be inclined to the axes of the wheels. The rear wheels 2 may be simultaneously or independently adjusted vertically relatively to the frame by turning their carrying-arms 10 about a transverse axis by means of either one or two levers 14. The front wheels 3 are adjustably connected to the frame by pins 18 passing through holes in the steering-post 17 and in the swivelling draught head 19.

Title: Method and apparatus for making filamentous products by winding
IPC: D04H3/02
Filed: 1968-03-19
Abstract: 1,224,356. Covering cores by winding. AMERICAN AIR FILTER CO. Inc. 19 March, 1968 [5 April, 1967], No. 13357/68. Heading B8G. Filamentous mats are formed by feeding a curtain 3 of filaments on to a rotating drum 1 from which the mat can subsequently be removed by cutting and selectively inserting filament collector means 8 into the curtain of forwarding filaments so that a portion of the filaments contact the surface of the collector means to be urged into contiguous relation to form multifilament strands to be wound on the drum. As shown, glass filaments are fed from feeder 2 which reciprocates along the drum. The collector means, e.g. cylinders 8 or wheels (32), see Figs. 9 and 10 (not shown), are suspended on a support from the feeder 2 and are preferably rotated about an eccentric axis by motor 9, see also Figs. 3, 4 and 5 (not shown). The collector cylinders 8 may have conical or hemispherical ends to assist in penetration of the filament curtain. The collector cylinders 8 may have different diameters. A collector rod 11 may be disposed so as to contact at least a portion of the filament curtain and thus narrow the depth thereof in a direction normal to its width, see Figs. 3 and 11 (not shown). The collector rod may form part of the collector means when the wheels (32) mounted on the rod form the collector means. The collector rod may be rotatably driven, e.g. by motor 13.

Title: Production of acetylene
Inventor: DANZ WILLI
IPC: C07C2/78
Filed: 1962-04-11
Abstract: In the production of acetylene by subjecting hydrocarbons to high temperatures, the hot gas is quenched in a single stage by injecting a hydrocarbon oil boiling above 150 DEG  C. in a volume ratio to gas (measured under standard conditions) of at least 1 : 100 without any appreciable cracking of the oil and separating the hot oil containing carbon black from the gas. The oil is preferably an aromatic oil and useful heat is extracted from it before its reuse; the carbon black content is preferably reduced to below 35% by weight e.g. by removing part of the oil and replacing this by fresh oil.  The gas is preferably also later washed with an oil boiling in the range 80-450 DEG  C. having a specific gravity below 0.95.  The examples relate to the partial combustion of gasoline and of methane; reference is also made to heating hydrocarbons by electric discharge and exposure to hot flame gases.

Class 123(2) In a forced-flow, once-through boiler wherein the evaporator tubes are assembled in groups in each of which a number of parallel-connected tubes 3, 4 open into lower and upper headers 1, 2 and wherein downcomer tubes 5, 6 interconnect the groups for sequential flow of water and steam therethrough, the tubes 3, 4 are respectively connected into the headers at the upper and lower sides thereof whilst the downcomers 5, 6 extend upwardly into the upper header 2 as shown at 7 so that during low load operation a quantity of water will collect in the header 2. Whilst the boiler is operating at full load the tubes 3, 4 all act as riser tubes. At low loads the tubes 3 continue to act as risers but the flow direction in the tubes 4, which are of relatively larger diameter but only one third in number of the tubes 3, reverses and these tubes act as downcomers conveying the water collected in the upper header to the lower, a natural circulation thus being established which maintains the minimum velocity required in the riser tubes 3 to avoid overheating thereof. In a modification, the tubes 4 are replaced by large diameter, unheated downcomers one of which is provided, for example, for every ten riser tubes.
