Abstract: FIELD: shooting. 
     SUBSTANCE: invention relates to small arms ammunition and is aimed at firing at lightly armored targets as well as at manpower equipped with personal body armor. An armor-piercing bullet contains a shell with a core placed in it. It is made with a truncated cone, pointed at the front. The core has four stiffening ribs from the nose to the base of the truncated cone. These ribs have an inclined profile and are made with the possibility of cutting the armor to form petals. The conical part is made with the possibility of wrapping the formed armor petals inward with the expansion of the formed hole due to the possibility of adding the explosion energy with the kinetic energy of the bullet. An explosive substance is poured behind the core so that it can be driven by a primer sleeve with an initiating charge fixed in the partition. A glass is fixed behind the partition with a nut. A striker is installed inside the glass with possibility of free movement, abutting against the safety spring.

After performing a craniotomy, the dura mater (dura) is opened in the projection of the pathology and the electrode strip with the cylinder is inserted under the edge of the bone defect so as to be located in the projection of the motor cortex of the brain. The position of the electrode strip is visually monitored, and in the absence of contact of the electrodes thereof with the dura, air is supplied to the cylinder to provide such contact. A control signal is provided, recording the amplitude of the response Amax signal. The operation is performed under neurophysiological control, in the process whereof, as the brain retracts, the cylinder is inflated to ensure a tight fit of the electrodes of the apparatus against the cerebral cortex while the value of the amplitude of the response signal A is monitored ensuring compliance with the condition A≤Amax. 
     EFFECT: intervention on the brain is conducted with a reduction in the risk of injury to the corticospinal and corticobulbar tracts, increasing the safety of neurosurgical intervention and reducing the risks of neurological complications due to the use of an electrode strip following the relief of the surface of the cerebral cortex when placed thereon with distribution of pressure along the length of the electrode strip for improved contact of the electrodes with cerebral tissues without the risk of compression disruption of the blood supply in the contact area.

Title: Controllable thermal insulation for buildings etc. - where unstable foam providing insulation can be pumped through cavity wall
IPC: F24S10/50
Filed: 1969-12-03
Granted: 1983-06-01
Abstract: A building or structure uses at least two walls to form one or more cavities, which can be filled with an unstable foam forming thermal insulation. A foamant is dissolved in a liq.; and a gas, e.g. air, is injected into the liq. to make a foam fed into the cavity. When the air escapes from the liq., the foam collapses, and the liq. is recycled via a drain into a tank, from which it can be re-injected into the liq. through a pump. Two cavities contg. different foams may be formed by using a triple wall. One pref. building uses a tank from which the foamant soln. is pumped through a nozzle into a stream of air, so a foam travels downwards through the wall cavity into a drain. The foamed insulation can be removed from cavity walls. The liq. can also be fed through the wall to collect solar heat during the day, this heat then being used during the night.
