In a vehicle spring suspension system comprising at least one coil spring operating under compression and at least one auxiliary spring disposed laterally with respect to the coil spring and operating in tension, the coil spring bears through its lower end on a member rigid with the unsuspended part of the vehicle, while a bracket is fitted between the upper end of the coil spring and the suspended part of the vehicle and includes at least one integral laterally-extending arm, the auxiliary spring or springs connecting a point of the unsuspended part of the vehicle near the lower end of the coil spring with a corresponding point on the outer end of each arm, which latter point is horizontally spaced with reference to the firstmentioned point on the member rigid with the unsuspended part. In the arrangement shown, in which a coil spring 4 is retained between a bracket 3 secured to a chassis member 1 and a cup 5 rigid with an axle 2, a carrier member 6 is interposed between the spring 4 and bracket 3 and includes two downwardly directed and laterally-extending arms 8, 8<SP>1</SP> to the ends 9, 9<SP>1</SP>, of which are secured tension springs 10, 10<SP>1</SP> which are connected through a strap 12 to the axle 2. During assembly, the spring 4 may be held in compression by hooks 15 which are automatically released, when the mounting is subjected to load. In another arrangement, (Figs. 3 and 4, not shown), for the suspension of a rigid rear axle, the carrier member 6 at each side of the vehicle includes only a single arm and. tension spring which lie in a plane substantially paralled with the axle. The carrier member and cup may be adjustable angularly relative to the chassis and axle respectively and a rubber pad may be interposed between the carrier member and the chassis.

Filed: 1928-06-16
Abstract: 322,998. Moulton, H. F., and Tschudin, E. June 16, 1928. Cellulose nitrates.-Wood pulp is subjected to long continued agitation with water in a hollander or like machine, for example for 3 hours, to form a slime or pulp, which is then formed into strips, which are spun into string-like form and cut into pellets, for example 0.5-1 millimetre thick and about 0.5-1 centimetre long, as described in Specification 322,997. The pellets, in an air dried state, are then nitrated, preferably in a centrifugal nitrator, by means of a nitration mixture in which the nitric acid exceeds the sulphuric acid. Alternatively the material in string-like form can be nitrated and treated in subsequent processes and then cut into pellets. A suitable nitration mixture comprises, for example, 81 per cent nitric acid, 16 per cent sulphuric acid, and 3 per cent water to give a nitrated product containing 13.2 per cent of nitrogen, but if lower nitrations are required the relative proportion of sulphuric to nitric acid may be increased. The nitrated pellets may be freed from nitrating acid. preferably in a centrifuge, washed, stabilized bv boiling, dried till their water content is reduced to from 10-20 per cent, and then gelatinized.

Title: Process of separating into constituents animal and vegetable tissues or organs
IPC: A61K35/12
Filed: 1930-06-06
Abstract: To isolate individual organized constituents from animal or vegetable tissues or organs, e.g. in preparing active fractions from glands having internal secretion for example the thyroid gland and the pancreas, the tissues &c. are dried in a frozen state and powdered after which the coarser parts may, if desired, be separated from the finer parts, the desired constituent being finally isolated by treating successively with liquids of different specific gravity. The tissues may be frozen by means of the usual cooling media e.g. solid carbon dioxide and ether, or liquid air and the separating liquids may be chloroform containing for example 25, 20, 15, 10, and 5 per cent of ether and pure chloroform, a finer fractionation being carried out on the suspension containing the desired constituent. Examples are given of the isolation of muscle nuclei from beef and of colloid from the thyroid glands of pigs, the glands being frozen, dried in a sulphuric acid dessicator, treated to remove as far as possible the fat and connective tissue, ground and sifted and subjected to a double sedimentation in ether, the colloid being finally separated from the second sediment by centrifuging successively with mixtures of chloroform and ether.ALSO:To isolate individual organized constituents from animal or vegetable tissues or organs, e.g. in preparing active fractions from glands having internal secretion for example the thyroid gland and the pancreas, the tissues &c. are dried in a frozen state and powdered after which the coarser parts may if desired be separated from the finer parts, the desired constituent being finally isolated by treating successively with liquids of different specific gravity.

Class 83 (4) In arc welding a first arc is drawn between the workpiece and a covered electrode so pivotally mounted that it is inclined to the workpiece with the covering of the free end in contact with the workpiece and a second arc is guided by a manually' operated electrode as melting of the first electrode takes place. In an embodiment a coated electrode 2, Fig. 1, is pivoted at 24 on a fixed column and a transformer 6 is connected between the electrode and the work 4. A further transformer 5 is connected between the work and a manually guided electrode 1 whose arc may be with the work or the pivoted electrode. In operation the pivoted electrode settles on the work under its own weight. It may be pressed by a spring &c. In one modification each electrode is supplied from a convertor and in another a transformer supplies the pivoted electrode while a converter supplies the other. In the latter case a relay may be inserted in the pivoted electrode circuit with its winding serrated on the other electrode circuit for arc control. The pivoted electrode may be curved and as shown in Fig. 8 has a double curvature. The pivotal mounting may automatically move towards the workpiece to keep the electrode inclination constant while the diameter of the pivoted electrode may be greater than that of the other. Two or more electrodes in a common covering may replace the single pivoted electrode. In order that the pivoted electrode may be moved along the welding seam a pivoted holder 45, Fig. 10, is provided on a frame 31 having one or more rollers 32 running in the weld gap and having laterally supporting rods 34-37. The rollers may be motor driven.
