Abstract: FIELD: construction industry, particularly, methods of construction of foundations in rammed down foundation pits on soft and settling grounds for industrial and civil buildings and structures. SUBSTANCE: pile-slab foundation includes main slab of preset size in plan and toothed supports joined to slab lower side and installed on reinforced or compacted ground. Novelty in pile-slab foundation consists in that it has additional lower horizontal slab with rigidly exceeding that of natural grounds and connected with main slab through toothed supports and stiffening ribs located from lower side of main slab in number corresponding to at least number of structure bearing walls. In this case stiffening ribs at least in points of wall crossing are provided with toothed supports. Method of construction of pile-slab foundation includes excavation of common foundation pit with horizontal area for main slab, ramming down on bottom of common foundation pit of pits for toothed supports, successive filling of pits for toothed supports and common foundation pit with mechanically binding material. Novelty of the claimed method consists in that additionally rammed down on bottom of common foundation pit are pits for stiffening ribs. On bottom of some part of pits for stiffening ribs, pits for toothed supports are rammed down. Additional horizontal slab is provided with rigidly higher than that of natural ground by its compaction and introduction of additional material or hardening liquid mass into ground through pits of toothed supports or pits of stiffening ribs.

Title: Remote-control blasting devices for jet projectiles of salvo-fire systems
Inventor: VORONKOV N M
IPC: F42B15/00
Filed: 2000-06-06
Granted: 2001-06-20
Abstract: FIELD: military equipment, in particular, remote-control explosive devices for salvo-fire systems jet projectiles with cassette or separated warheads. SUBSTANCE: for taking into account the deviation of the actual parameters of projectile motion from the design ones and correction of the preset time of remote actuation the remote-control explosive device uses an accelerometer and a computer realizing the correction algorithm, taking into account the projectile velocity in a fixed point of the trajectory, the coefficient and functional introduced in the pre-launch procedure. At projectile launching signals corresponding to the projectile axial acceleration start arriving at the computer input. In a fixed point the computer determines the projectile velocity and realizes the preset algorithm. To prevent the influence of deviation of the accelerometer parameters (initial frequency f o ) caused by prolonged storage, dependence of f o  on temperature and other factors, an automatic frequency control (AFC) unit is introduced in the correction unit. This unit has a frequency subtraction circuit, the first and second frequency dividers, controllable frequency divider, flip-flop and an additional oscillator. Besides, the electronic time device has a correcting signal analysis unit, which keeps up with the fact that the total number of correction pulses would not exceed the maximum allowable value. EFFECT: enhanced accuracy of deployment or separation of the warhead in range. 3 cl, 3 dwg
