| 20090137349 | Device for Training and Improving a Volleyball Spike Technique - The invention relates to sports training devices and can be used for training a volleyball spike-motion. The inventive device comprises a bearing frame, a ball, and a unit for returning the ball to the initial position thereof, which unit is provided with an elastic stretching connected to the frame by one end thereof, a rod whose one end is fixed to the frame in such a way that it has at least two degrees of freedom, whereas the second end of the rod is connected to the ball, and the second end of the stretching is connected to the rod. The frame is also provided with a limiter of traveling the rod. The device enables the ball to be moved along an arc, thereby increasing the quality of the spike-motion training, and improves effectiveness and safety of the training. | 05-28-2009 |

| 20110067444 | Processes and Device for Low Temperature Separation of Air - The process and device serve for the low-temperature separation of air in a distillation-column system includes at least one separation column. A main air stream is compressed in an air compressor at a first pressure and is then purified. A first air stream, which is formed from at least one part of the purified main air stream, is further compressed at a second pressure that is higher than the first pressure. From the further compressed first air stream, a throttling stream and a turbine stream are branched off. The throttling stream is cooled down and liquefied or pseudo-liquefied in a main heat exchanger and is then passed on to expansion equipment. The expanded throttling stream is conducted into the distillation-column system. The turbine stream is cooled down in the main heat exchanger and under an intermediate temperature of the main heat exchanger is conducted into an expansion machine. | 03-24-2011 |
| 20110083469 | Process and Device for Obtaining Liquid Nitrogen by Low Temperature Air Fractionation - A device for obtaining liquid nitrogen by low-temperature air fractionation in a distillation column system for nitrogen-oxygen separation includes a high-pressure column; a low-pressure column; a high-pressure column top condenser which is constructed as a condenser-evaporator and comprises a liquefaction compartment and an evaporation compartment; a low-pressure column top condenser which is constructed as a condenser-evaporator and comprises a liquefaction compartment and an evaporation compartment. A throttle stream is formed by one part of a purified feed air that is liquefied or pseudoliquefied in a main heat exchanger. The throttle stream is expanded, and at least some of the expanded throttle stream is introduced as refrigerant stream into the evaporation compartment of the high-pressure column top condenser. | 04-14-2011 |

| 20110231673 | CRYPTOGRAPHIC PROCESSING USING A PROCESSOR - In one embodiment, a cryptography processor compatible with the Advanced Encryption Standard (AES) for encrypting and decrypting has a memory storing each element of an AES State, normally 8-bit long, in a corresponding memory space that is at least 9 bits long. Using the larger memory spaces, the processor performs modified AES transformations on the State. A modified column-mixing transformation uses bit-shifting and XOR operations, thereby avoiding some multiplications and modulo reductions and resulting in some 9-bit State elements. A modified byte-substitution transformation uses a 512-element look-up table to accommodate 9-bit inputs. The modified byte-substitution transformation is combined with a modified row-shifting transformation. The memory has data registers each holding four State elements. A modified expanded key schedule is used in a modified round-key-adding transformation that is combined with the modified column-mixing transformation, wherein all four elements stored in a single data register are processed together in some operations. | 09-22-2011 |
