Title: Methods of producing vaccines and sera
IPC: A61K39/00
Filed: 1947-07-29
Abstract: Vaccines or sera are produced from micro-organisms by irradiating the micro-organisms with high speed electrons having a velocity equivalent to more than one million volts during one or more very short time periods lasting less than say 10-4 second so as to destroy their faculty of propagation without destroying their antigenic properties.  The irradiation may be from several directions simultaneously.  The micro-organisms may be placed in an electron permeable sealed container or sealed in the final bottle or ampoule and may be cooled below 0 DEG C before irradiation.  The sealed container may be avacuated or may contain an inert gas and may be rotated during irradiation to facilitate uniform treatment.  Examples are irradiated with 4 million volt electrons for 2 periods 10-6 second.  The source of radiation and the sealed container should be of the type described in Specification 673,924, [Group XL(a)]. Micro-organisms specified are bacteria such as Strep. hemolyticus, prodigiosus, sporogens, Staph. aureus, coli, tetani, subtilis, pneumoniae, proteus, pyoceaneus, dysenteriae, diphtheriae, tuberculosis, pertussis, anthacis, botulinus, and viruses such as rolled leaf, rabies, vaccinia, hog cholera, influenza, poliomyelitis, chicken leukemia, equine encephalitis, mumps, newcastle of fowl.  The Specification as open to inspection under Sect. 91 comprises also irradiation under pressure of 2,000 lbs./square inch at -20 DEG  to -100 DEG C.

Title: Improvements in automatic adjusting device for brake members
IPC: B61H15/00
Filed: 1929-07-06
Abstract: 334,318. Boirault, L. July 6, 1929. Compensating for wear.-In the brake transmission mechanism, particularly of railway vehicles, is arranged a connecting member 6 whose length is automatically altered in accordance with the wear of the shoes by a cam 12 turned by a pawl 15 actuating a coaxial ratchet sector 16, a resilient member such as a spring 39 being provided in the mechanism for turning the cam which absorbs excess movement due to deformation of the rigging during braking. The member 6 is pivotally connected by pins 5, 7<a> between the beams 3, 7 pivoted to the piston rod 2 and brakeactuating cylinder 1 respectively and connected by links 4, 8 to the brakes. The spiral cam 12 acts on a member 11 carrying the pin 5 which engages slots 10 in the forked end of the rod 6 so that as the cam is turned the distance between the pins 5, 7<a> is decreased. The pawl 15 is carried by a lever 14 pivoted on the shaft 13 of the cam and having a slot engaged by a pin 2<a> on the piston rod 2. A stop 38 is provided on the cam 12, and the spring 39 acting between an extension 40 on the cam and the ratchet sector 16 forces the ratchet sector against the stop. When due to wear the stroke of the pawl 15 on the release movement exceeds the pitch of the teeth the cam 12 will be displaced during the next application, the spring 39 allowing further movement of the rigging after the shoes are applied, without moving the cam. A spring 42 on the shaft 13 causes friction between the parts sufficient to prevent reverse movement of the cam. Fig. 5 shows a modification in which the ratchet 16 and cam 12 are rigidly fixed on the shaft 13 and the lever 14 terminates in an arm 35, a spring 36 being interposed between the arm 35 and the pawl 15 which has a slot 37 engaging a pin on the lever 14 so that the ratchet is driven only with a limited force. The resilient device may be arranged between the lever 14 and the pawl or between the lever and the pin 2<a>. To prevent accidental movement of the cam 12 a second ratchet may be secured to the cam and engaged by a spring-pressed pawl mounted on the rod 6. Fig. 11 shows a modification in which the beam 3 connected to the piston 1 at 9 is pivoted at its other end at a fixed point 49 and the connecting member 6 is pivoted to the beam 3 and carries the spindle 13 of the cam 12. A forked member 50 is slidable on the member 6, having slots 53 in which the spindle 13 moves and a stud 52 slidable in slots 58 in the member 6. A roller 50<a> on the member 50 engages a rocking lever 51 by which the brakes are applied. The lever 14 carrying the pawl 15 is connected by a rod 54 with a fixed part 55 of the framework, a spring 56 being interposed. After the last tooth of the ratchet a smooth space 16a is provided greater than the maximum stroke of the pawl so that the cam cannot be moved further.
