Title: Improvements in or relating to process for deresinating rubber from plants
IPC: C08C3/02
Filed: 1951-07-17
Abstract: Guayule rubber-bearing material is simultaneously dehydrated and deresinated by mixing such a material in the form of wet guayule shrub and wet resinous guayule rubber with a partially water-miscible resin solvent which dissolves water at room temperature in a range of about 1 to 20 per cent., separating the guayule rubber-bearing material from the mixture, allowing the remaining liquid to stand, forming an aqueous phase and a solvent phase containing dissolved resin and separating the phases. Specified partial solvents are methylethyl ketone, n-butyl alcohol, sec-butyl alcohol, isobutyl alcohol, n-amyl alcohol, tert. amyl alcohol, butyraldehyde, benzyl alcohol, nitromethane, nitroethane and furfural.  The process may be a batch process in which the solvent and aqueous layers are allowed to settle out and separated, or may be continuous, in which case the liquids are continuously separated by a syphon take-off.  In an Example, wet guayule "worms" are extracted with a methyl ethyl ketone and water azeotrope and the resulting rubber compounded with stearic acid, zinc oxide, mercaptobenzthiazole, sulphur and diorthotolylguanidine.

IPC: B62D1/10
Filed: 1928-06-12
Abstract: 318,680. Husted, H. A. June 12, 1928. Hand-wheels.- In motor-vehicle steering- wheels comprising a sheet-metal reinforcing- spider B, Figs. 2, 6, and 7, embedded in moulded hard rubber or other compositions A, the, rim and spokes, and preferably also the hub, of the spider are integral and have continuous stiffening- means which merge into one another at the junctions of the parts, in order to impart great strength and rigidity to the wheel. The rim 1, large hub 2, and short spokes 3 of the spider have upwardly-directed marginal flanges 4 - - 8 and upwardly-directed central ribs 9 - - 11. The flanges 5, 6, 7 are continuous, and the wide rib 10 of the hub merges into the ribs 11 of the spokes, which taper to merge into the narrow rib 9 of the rim. The spider is downwardly dished to a greater depth than the wheel, as shown in Fig. 2, so that the hub 2 lies near the bottom surface and the rim 1 near the top. The rim 1 is still more deeply dished, in order to reduce its width. The ribbing forms continuous channels, through which gases, trapped during moulding, can escape towards the rim. Perforations 20 in the spider help to " key " the composition. The spider blank is shaped between discs 30, 32, Fig. 10, the lower die 30 having pins, Fig. 9 (not shown), engaging the angles between the rim and spokes to prevent distortion during dishing. The final closure of the dies forms the flanges and ribs, and also tongues 33 to position the spider in the mould. In the three-spoked wheel shown, one spoke, having a distinguishing-mark, points towards the driver when the road-wheels are undeflected. The wheel is secured to the steering-pillar top 21 by screws 22 and a plate 23, Fig. 2.

The servo sectors for the start of all the tracks lie along a common radius of the disc. As shown in Fig. 3, the disc is divided into four bands, with a common radial starting point 28 for data sectors A1, B1, C1, D1 of each band. Adjacent sectors e.g. Al A2 are separated by servo sector 30, and the home address sectors for each band AOD0 are of different lengths, and contain record track identification and control information. In order to control the position of a read head over a data track, the head output on line 70, Fig. 8, including servo and data information, is fed to a synchronous demodulator 120 that is synchronized by a variable frequency oscillator 121 slowed to the input on 70. The separated data and servo control information are sent respectively to AND gates 122, 123 that also receive signals on line 87. This signal is positive when servo sectors are sensed by the read head, and negative when data sectors are sensed. The resultant output of gates 122, 123 are used to respectively control data handling apparatus and a head positioning control, so that the head follows the data track. The signal on line 87 is supplied by a circuit, Fig. 4 (not shown) in which a disc angular position register is updated by a ROM for each data or servo sector sensed.
