Abstract: 1494853 Antilymphocyte Serum INSTITUT FRANCAIS D'IMMUNOLOGIE 18 July 1975 [19 July 1974] 30320/75 Heading A5B Antilymphocyte serum active against human lymphocytes is produced by administering human lymphocytic antigenic material to an animal, collecting the resulting antilymphocytic serum, and purifying it by contacting it with human placental tissue, after which the purified serum is collected. The antigenic material which may be lymphocytes from the thoracic duct or thymus of human beings, is administered to a horse over a period of weeks or months, and then plasma is obtained from the animal. The plasma is preferably treated with 2 - ethoxy - 6, 9 - diamino - acridine lactate at pH 7 to 8 to remove albumens and # - globulins, and then filtered. The placental tissue is prepared by grinding and fixing e.g with glutaraldehyde or formaldehyde, followed by heating at up to 60‹C for 10 hours to inactivate any viruses or bacteria present. The serum is then mixed with the fixed placental tissue, brought to pH 7Œ0.2 and left for about 1 hour with aeitation, and then separated from the tissue. This procedure may be repeated several times until the serum is free from haemaglutinin and haemolysin activity. The serum may then be concentrated by ethyl alcohol fractionation to precipitate an active antilymphocyte fraction, the precipitate then being taken up in buffer at pH 5-6, and dialysed against water. The preparation may be finally purified by chromatography on alumina gel or an ion exchanging cellulose derivative.

Title: Improvements in or connected with organ control
IPC: G10B3/10
Filed: 1924-12-18
Abstract: 248,863. Rutt, R. S. Dec. 18, 1924. Organ stop and combination actions. - Grooves or reduced portions are formed on the draw-stop rods so that with the stop "in," the slidermechanism is connected to exhaust, but on drawing the stop out the slidermechanism is connected to wind. The slider-mechanism control is formed as a unit arranged behind the stop-jamb. Pneumatic devices controlled by pistons may be added for obtaining both fixed and adjustable combinations of stops. The grooves in the draw-stop rods 9, Fig. 2, are of the form shown at 33, Fig. 4, and in the " in " positions connect side passages 8 leading to the slider -mechanisms, to exhaust in chambers 3. In the " out " positions, however, the passages 8 are connected to wind in a chamber 4. Fixedcombination pistons are connected at 21a, and when one is operated a membrane 22 falls, admitting wind to ducts 20 open according to the combination, and lifting valves 18 so as to allow wind to pass from chamber 4 by passages 17 either to the front or to the rear of the membranes 13 attached to the drawstop rods 9. Adjustable combinations of stops are obtained by a unit in part shown in Fig. 4, and comprising valve-rods 30, dispersal-membranes 27, and setting-membranes 36. The valve-rods have. each two grooves 33, 33<a> and a gate 32 controlling " on " and " off " ducts 31, 31a connected to the ducts 24, Fig. 2, and actuating the slider mechanisms through the passages 8 as before. To disperse previous combinations, all draw-stops are put in, and the membranes 27 are operated by a three-way switch (not shown), which is turned by hand to a position admitting wind to a membrane operating a valve so as to permit wind to pass from a relay pressure chamber to the chamber 25 communicating with the membranes 27. To allow setting of the required combination, the switch is then operated to admit wind to the mebrane of another valve which cuts off the connection of chambers 38 to the relay pressure and connects them to exhaust, thus allowing choke membranes 38<a> to uncover the adjacent ports of passages 37, 35. To set the combination, the stops 11 corresponding thereto are drawn, permitting wind to pass from bye-pass tubes connected to the passages 8, and through the passage 37, 35 to the membranes 36 throwing the selected valverods 30 to the " on " position. By turning the switch to a third position, the choke membranes 38a close the ports 37, 35 and allow free use of the draw-knobs by the " fixed pistons " or by hand. To bring on the combination which has been set, an " adjustable piston " is operated to open a valve which connects to the relay pressure a chamber 44 communicating through the gates 32 with the slider-mechanisms.
