Patent GB-381055-A (GB)
Title: Improvements in or relating to the production of strictly specific antigens or vaccines
IPC: A61K39/02
Filed: 1932-01-28
Abstract: Specific antigeus or vaccines are prepared by cultivating micro-organisms in vitro on culture media and under conditions as similar as possible to those in which the micro-organisms existed in vivo.  The microbes so cultivated reproduce the antigenic properties they possessed in vivo.  The culture medium consists of a body fluid such as serum, defibrinated blood, exudate, organ or tissue extract obtained from an animal of the same species as that from which the micro-organism is obtained.  For example in the case of bovine tubercle, the micro-organisms are cultivated on a bovine medium and when the culture has grown sufficiently it is inoculated on to a normal bovine medium in a glass flask and kept at 38,5-39 DEG  C. until sufficiently developed.  The micro-organisms are then collected and made into an emulsion, preferably in absence of oxygen with water or normal saline solution, put up in ampoules and kept in the dark until the micro-organisms have died a natural death, when the emulsion is ready for use.  Traces of antiseptics e.g. formaldehyde may be added to the emulsion before sealing it into the ampoules. For the treatment of human beings three types of tubercle vaccine may be employed, i.e.  (1) a vaccine made from bovine tubercle grown on bovine media; (2) a vaccine from bovine tubercle grown on human media; and (3) a vaccine from human tubercle grown on human media. The three vaccines are mixed in varying proportions according to requirements.  The antigens may be prepared with dead or alive bacterial bodies, with an extract of the bacterial bodies or with the specific liquid on which the bacteria have grown.  The antigens may be used for preventive vaccination, therapeutic vaccination, the preparation of antitoxin and antibacterial sera and for test purposes.

Patent GB-162099-A (GB)
Title: Improvements in and relating to fuzes for explosive shells and the like projectiles
IPC: F42C15/22
Filed: 1920-01-28
Abstract: 162,099. Last, J. J. Jan. 28, 1920. Projectiles and fuses. -Relates to percussion fuzes in which the firing-needle is carried by a movable member which is displaced by centrifugal force during flight to bring the needle into line with the detonator. According to the invention, the needle 29 is fixed on a centrifugal shutter 27 pivotally mounted on a non-movable component or plug 6 of the fuze. The plug 6 contains the momentum pellet 10 which is held in place by a centrifugal bolt 23 which can be locked by a pin 17 or a lever on an inertia detent 19 adapted to set back to release the bolt 23 when the projectile is discharged from a gun. The flash from the detonator cap 14 passes down a port 15 through the momentum pellet, and along ports 35, 37, 36 in the body 1 of the fuze to a gunpowder ring 45 in a head-piece 43 provided with flash holes 44 and screwed to the end of the fuze body. Paper tubes and powder pellets 39 perforated or solid according to the delay required in the transmission of the flash are put in the flash passages, which are normally obturated by a centrifugal shutter 47 disposed beneath a disc 52 behind the momentum pellet 10; this shutter opens a passage for the flash only when displaced by centrifugal force during flight. The needle-carrying shutter 27 is normally held in the inoperative position by a spring 30 and is further gripped by a spring 31. On discharge, the spring 31 releases its grip on the shutter, and after the shutter has been displaced by centrifugal force and has brought the needle in line with the detonator, the spring 31 snaps against a flat 56 on the side of the shutter and thereby prevents its return. The flash obturating shutter is controlled by a spring similar to the spring 30 and by a detent which sets back on discharge to release the shutter. A similar detent may be used for the needle carrying shutter, which is covered by a cap 33 screwed to the plug 6. The body 1 of the fuze is preferably made of brass, aluminium, or gun-metal. A " tracer " 42<1> is screwed into the base of the fuze body 1. The joint between the fuze body and the projectile to which it is screwed is made flash-proof by means of a fillet 55<1> of asbestos rope against the flange 2 of the fuze body.
