Title: Manufacture of extracts of spleen or liver
IPC: A61K35/407
Filed: 1936-10-05
Abstract: Medicinal preparations which are efficaious against bacterial toxins are prepared from liver or spleen by subjecting the tissue to autolysis without addition of acid and then extracting the autolysate with water, or a water-soluble organic solvent, with the addition of a little acid and at a low temperature, and treating the solution with an agent to eliminate ballast substances, particularly proteins. The clear liquid obtained may be dried, and the residue extracted with concentrated methyl alcohol to yield a solution which is dried. Pure or aqueous methyl alcohol may be used as the extracting agent for the autolysate, and iron dialysate or lead acetate may be used to eliminate ballast substances.  The Specification as open to inspection under Sect. 91 refers also to extraction of the liver or spleen of normal animals for a prolonged time at low temperature at a pH between 4 and 6 without previous autolysis, and to simple extraction at a feebly acid reaction of the organs of immunized animals; it states also that organic solvents without addition of acid may be used for the extraction and that the extracts so obtained are poor in ballast substances such as albumin and electrolytes.  An example relating to the extraction of the spleen of an immunized animal with N/100 hydrochloric acid, followed by purification by means of iron dialysate is included.

Title: A forward and reverse gear control for locomotives and railcars
Inventor: LEAVER RALPH HAWORTH
IPC: B61C17/12
Filed: 1959-08-17
Abstract: 884,758. Change-speed control. ROLLS-ROYCE Ltd. Aug. 9, 1960 [Aug. 17, 1959], No. 28058/59. Class 80 (2). [Also in Group XXXI] The invention relates to a " miscible " control system for mixed multi-coach railcar sets or coupled locomotives of which at least one has a mechanical gear-box of the epicyclic type actuated by friction clutches and the remainder have torque converter transmissions with a " neutral " clutch to disengage the drive to the impeller. It so happens that the drive in neutral of the clutches of the epicyclic transmissions is sufficient to rotate the reverse drive dogs and to ensure engagement of forward or reverse drive. In the case of the torque converter transmissions, the drag of the neutral drive clutch is not usually so adequate and dog engagement can be effected only by the momentary engagement of " drive." If this were done by the driver, all of the train would be involved, and should any of the reverse drive dogs of the epicyclic transmission not be engaged, they could become damaged. The invention provides means whereby in the torque converter drive cars only, should any one of the reversing dogs not engage, the engine of that particular unit is automatically set at idle, should the driver have failed to do so, and the transmission is placed in " drive," and returned to " neutral " when the dogs are fully engaged. Operation of a direction selector switch 1 energizes the forward or the reverse relays 3 or 4 which control electromagnetic valves controlling the supply of compressed air to the servomotor controlling engagement of the forward or reverse gear dogs. Full engagement of the gear dog teeth closes a detector switch 7 which energizes a relay 9 completing a circuit through an indicator lamp 11 in the driving cab. If the forward/reverse gear dogs fail to engage, and with a deadman's handle 2 depressed, relay 9 remains de-energized and a drive relay 16 and rack idle relays 17, 18 are energized. Energization of the relays 17, 18 ensures that the engine idles. The closing of the contacts of relay 16 energizes an electromagnetic valve which then supplies air through a one-way choke 20 to a torque converter control valve and engages hydraulic drive. The choke 20 ensures that the engine idles before hydraulic drive is engaged. When the gear dogs mesh, switch 7 causes relay 9 to be energized and the drive and rack relays 16, 17, 18 will de-energize. The converter will immediately return to neutral, but a choke 21 in the rack actuator line will cause a short delay before the speed of the engine can be increased.
