Filed: 1917-12-31
Abstract: 121,640. Jensen, C. A., (Oliver Chilled Plow Works). Dec. 31, 1917. Ploughs.-The plough frame 2 is attached to a tractor by a shackle 52 with vertical and horizontal pivots 54, 51 and is supported from land and furrow wheels 7, 8 by separate cranked axles 15, 21 which pass through bearings spaced considerably apart in brackets 12. A power mechanism is provided for raising the plough off the ground. A shaft 28 in advance of both axles terminates in an eccentric toothed segment 29 which can be put in gear with a spur wheel 30 attached to the land-wheel, by means of a hand-lever 41 acting through arms 37, 39 and a coupling-rod 38. This being done, the plough frame is tilted from the ground about the hinge made with the tractor. An arm 31 on the crank-axle 15 is connected to a pivot 35 on the bracket by toggle-linkage 32, 33 and, just before the intergearing fails at the toothless end of the segment, the linkage locks the frame against falling and the segment may be set back to its original position on the frame. To let the plough drop again, the hand-lever 41 is used to make a spur on the shaft 28 trip the toggle. A manually-operable mechanism 19 is provided for adjusting the plough for depth and a screw 23 with handle 26 is provided to effect levelling adjustment.

In apparatus for heating successive, separate, portions of liquid which are moving along the lower part of a helical groove 222 in the internal surface of a rotating cylindrical reactor 10, as disclosed in Specification 916,677, a tube 214 is provided for introducing diluent liquid into each portion of treated liquid before it is withdrawn from the reactor. In carrying out a Kjeldahl nitrogen determination, each sample of liquid is mixed with sulphuric acid, and fed into the inlet end (not shown) of the heated reactor; and each digested sample is diluted with water introduced through pipe 214. The diluted samples flow successively into cylindrical groove 220, and are then drawn rapidly via tube 228 into receiver 224 while fresh samples of acidified liquid are being introduced into the opposite end of the reactor. The receiver 224 is maintained under reduced pressure by a source of vacuum connected to tube 230 which dips below the liquid in the receiver. The diluted liquid is drawn into tube 228 so rapidly that the inlet end 226 of the tube is uncovered by liquid, and air is drawn into the receiver 224, which agitates each successive portion of diluted liquid. The diluted liquid is aspirated from the receiver via tube 230, which leads to the analysis equipment, before the succeeding diluted sample flows into the receiver through tube 228. If the flow rate through tube 230 is less than that through tube 228, excess liquid is discharged from the receiver through tube 234. Specifications 817,070 and 834,635 also are referred to.

Title: Improvements in or relating to the manufacture of rubber filaments and the like
IPC: B29D99/00
Filed: 1927-07-25
Abstract: 297,912. Draemann, M. July 25, 1927. Extrusion machines.-In the manufacture of filaments by extrusion, a solution of unmasticated rubber is employed and the tendency of the filaments to change their shape during the process due to their elasticity is counteracted at each stage by means of the following provisions. (a) The solution is maintained at a temperature above the boiling point of the solvent. (b) The plunger displaces a volume equal or slightly less than that of the filaments emerging in the same time. (c) The nozzle is designed so that the solution is subjected alternately to high and low pressures. As shown the solution travels from an annular space v in communication with the cylinder of the press through a constricted central passage x in which the pressure is increased, to an enlarged portion y where it is reduced, thence through a sieve like insertion in which the pressure again rises to a chamber 2 in which it falls again, and finally through the extrusion cones 3. (d) The conveyer band e is situated at such a distance below the nozzle that the filaments are kept under sufficient tension by their own weight to prevent them from swelling. (e) The filaments are kept under tension by the band e which carries them through the drying chamber f and by the band q which takes them through the chamber g on which they are vulcanized by means of molten sulphur or hot air. (f) The filaments may be stuck together to form a band, before, during or at the end of vulcanization by means of liquid sulphur, glue, casein &c. to ensure that they shall all be drawn off finally at the same rate. (g) The conveyers at each stage are driven at the same speed as or at a slightly greater speed than those at the preceding stage the general speed being controlled in accordance with the operation of the press. Preferably a single source of power operates the press and the conveyers but if separate sources are used a common regulating device is provided to keep a proper relation between the various speeds. Talcum powder is blown at the filaments as they emerge from the press to remove the charge of positive electricity which they have acquired and prevent them from sticking together.
