Title: Therapeutic substance from human placental cord blood
IPC: C07K16/06
Filed: 1942-11-07
Abstract: A therapeutic agent is obtained by isolating blood from the human placental cord, freeing it from non-essential materials by allowing or causing it to clot and obtaining a serum by removing the clot. The serum may be further worked up by precipitating the globulin fraction, removing the non-essential elements, redissolving the globulin and adding a preservative.  An effective agent may also be obtained by merely oxalating or citrating the placental cord blood. The agents are suitable inter alia for treating measles.

Title: Process for heat-treating and stretching untwisted yarn consisting of a polymer of acrylonitrile
IPC: D02J1/22
Filed: 1944-08-21
Abstract: <PICT:0581526/IV/1> <PICT:0581526/IV/2> The tenacity of untwisted yarn consisting of a polymer of acrylonitrile is increased by spreading the filaments of the yarn into ribbon formation, passing the ribbon over a hot cylindrical surface whereby the filaments are rendered plastic, and stretching the yarn while the filaments thereof are spread out and in the plastic state.  Referring to Fig. 1, untwisted polyacrylonitrile yarn is fed from thread advancing roller 2 and snubbing roller 1, through a yarn spreading device 3 on to heated roll 4.  Rolls 1 and 4 have the same peripheral speed and the yarn is withdrawn from roll 4 at a speed greater than the peripheral speed of roll 4, whereby it is stretched.  After cooling the yarn may be twisted.  The yarn spreading device comprises two resilient thin sheets 3 exerting a mild pressure against each other and, if desired, a number of such devices may be used in series. Alternatively, the spreading device may comprise a series of rods over which the yarn is passed.  A device which directs air jets against the yarn so as to separate the filaments may be employed, or an electric charge may be applied to the yarn to cause the filaments to balloon out.  The cylinder 4 is heated by, for example, electrical means, high pressure steam, or hot vapours or liquids.  In a modification, a supplementary heating element 11 (Fig. 5) is affixed around roll 4, the yarn thus being heated from two sides.  The time of contact of the yarn with the roll 4 may be controlled by the diameter and speed of the roll; or by the angle of contact of the yarn on the roll.  In addition to polyacrylonitrile, the filaments of the yarn may consist of copolymers and interpolymers of acrylonitrile such as the interpolymers of acrylonitrile with vinyl and acrylic compounds, e.g. vinyl acetate, vinyl chloride, acrylic acid and its esters and homologues, styrene and isobutylene.  Dyes, pigments and dye modifiers may be added to the polymeric materials.

Title: Improvements in Submarine Mines.
Inventor: CANOSA JUAN MANUEL
IPC: F42C14/04
Filed: 1916-11-07
Abstract: 112,958. Canosa, J. M. Nov. 7, 1916. Mines, marine. - Relates to mines provided with a spring striker which is cocked and released by hydrostatic pressure admitted behind a piston in the mine when the mine is struck by a passing ship, and consists mainly in the provision of a safety device adapted to project in the path of the piston until a predetermined time after the mine is laid. In the form shown, the spring-striker 7 is connected to the hydrostatic piston 5 by a pivoted hook 9, which is rocked by the edge of a slot 12 to release the striker when the striker is retracted to the proper extent. An arm 2 is secured by pins 37, 38 to a socket 35 screwed to a bend 39 secured to the mine by a hollow nut 42. This bend is weakened by two grooves 40 nearly at right-angles to each other to facilitate breaking for admitting water through a pipe 3 to the cylinder 4 of the hydrostatic piston. Several such antennae may be used, and these may be con. nected to an annular pipe, which is connected to the cylinder 4 by the pipe 3. The hydrostatic piston is locked at safe by hinged arms 17, which are swung out of the safe position by a spring 28, when a soluble pin 31 releases a plunger 21. If the antennae are broken accidentally when the firing-device is inoperative, water leaks past holes 47 in the hydrostatic piston and sinks the mine; these holes 47 may be fitted with valves. The mine is salved by means of hooks 25 on the stem 21; and when these hooks are pulled up by the salving tackle, the arms 17 are brought back to the safe position, and springs 48 snap over a shoulder 49 thereby preventing re-arming.

Abstract: 838,425. Hay-making machines. VAN DER LELY N.V., C. May 21, 1957 [May 26, 1956], No. 16112/57. Class 6(3). A device of the rotary rake wheel type for laterally displacing crop lying on the ground, comprises at least one rake wheel provided with a stripper for removing soil from its tines. Referring to Fig. 2, the rake wheels each comprise a disc 42 mounted on its respective shaft, and a ring 43 bolted to the disc, the inner ends of rods 45 being clamped between the disc and the ring. The rods are then passed through holes in a rim 50 and are bent at their outer ends to form tines 49. An arm 51 carrying the stripper is also mounted on the rake wheel shaft, being formed at its inner end with a strap 52 which is clamped on to the shaft by means of a split collar 53 and bolts 54 and 55. The stripper is so arranged that the tines brush against it with a certain amount of pressure, the cleaning of the tines thus being ensured As shown in Fig. 1, the rake wheels, all of which are provided with strippers, are mounted on a beam 25 supported from the power lift links of a tractor. The coupling device between the beam and the lift links comprises a horizontal beam 10 and two upwardly slanting members 12 and 13 mounted between the ends of the lift links 3, 4 and 5. A ring 18 is mounted in the triangular structure so formed, so as to be rotatable about a vertical axis, the position of the ring being fixed by means of a pin 20 engaged in a hole in a strip 19 attached to the ring, and also in one of a plurality of holes in a semi-circular strip 16 fixed to the beam 10. A tube 21 is attached to the ring 18 so as to be pivotable about the horizontal axis 22, movement of the tube about this axis being restricted by a spring 23. A shaft 24 integral with the beam 25 is rotatably housed in the tube 21, rotation of the shaft being prevented when necessary by the pin 32 engaging holes in the tube and in the shaft. The construction may be modified by mounting the rake wheels on cranks rotatably mounted on a tractor-drawn beam, rotation of the cranks relative to the beam being restricted by springs in the usual manner, and in this case only the rearmost rake wheel is provided with a stripper.

Abstract: 311,570. Berkshire Printing Co., Ltd., Brooke, N., and Ballard, R. June 2, 1928. Packeting granular materials.-In machines in which tea and the like is packed into bags which are forwarded to a gumming and closing mechanism, means are provided whereby the gumming mechanism is started before the packing machine, and the latter is stopped before the former. This ensures, on starting, that the gumming mechanism is ready to operate upon any bags presented to it, and, on stopping, that no incomplete packets remain between the mechanisms. A motor a drives a friction clutch d and shaft c and transmits motion through reduction gear b and chain e to a shaft f. The shaft f drives the gumming mechanism through bevel gears g. The shaft f may also drive the packing machine through a dog clutch k, gears h, shaft i, (shown partially), and bevel gears j. The clutch k is arranged so as to engage only at the proper phase relationship. The clutches d, k are in mechanical connection with cams p, v. In order to start the machine, a pedal y is depressed, and, through a ratchet and pawl mechanism x, w, rotates the cams p, v so that the face-cam p acts, through links l, m, n, to bring the main clutch d into action and to start the gumming machine. After a sufficient interval has elapsed, the pedal is again depressed, causing the edge cam v to act, through links, q, r, t, on the clutch k and to start the shaft t driving the packing machine. At the end of the operation, a third movement of the pedal declutches the packing machine, and a fourth movement releases the clutch d and stops the gumming mechanism, the parts being returned to the initial positions.
