Abstract: By means of this method it is possible to produce projectiles with single- or multi-element projectile bodies of different shapes and sizes simply and in a time-saving way. The jacket (1) of the projectile consists of a projectile tip (3), which is fixedly connected with a projectile casing (2) and has a centering device (5, 9) in its interior, in which the projectile body (6) is guided and maintained. The projectile body (6) is essentially cylindrical or has a diameter which increases toward the rear. The back of the projectile casing (2) is closed by means of a sealing body (15), which partially extends around the projectile body (6). In the course of producing the projectile, the projectile tip (3) is injection-molded to the projectile casing (2) in a first step, and in a second step the projectile body (6) is pushed into the centering device (5, 9). In a third step the sealing body (15) is injected into the projectile casing (2), after which the projectile body (6) is completely enclosed in the injected material at the front at a shoulder (11), laterally, and at the rear.

Abstract: A process for enhancing the fuel form, raising the energy content, and lowering the level of impurities of low rank coals and/or carbonaceous waste s, like Municipal Solid Waste (MSW), Refuse Derived Fuel (RDF), and sewage sludge, by providing the low rank fuel, carbonaceous waste, or mixtures thereof ans a slurry in water of processable viscosity. This feed slurry is heated under pressure (118), usually in the presence of an alkali (109), to a temperature at which a significant physical and molecular rearrangement occurs, characterized by the splitting off of a substantial proportion of th e oxygen bound in the low rank coal or carbonaceous waste as carbon dioxide (147). At these conditions, solid particles in the feed slurry (103) lose mu ch of their fibrous and hydrophilic character, and are broken up into smaller particles of char, resulting in a slurry of dramatically improved rheology, i.e., capable of a much higher solids concentration (or energy density) at processable viscosity.

Abstract: Apparatus (10) for generating a radar waveform (W). A noises generator (20) generates a series of pulses in a pseudo-random pattern, and a frequency generator (16) generates a carrier wave having a frequency within a predetermined band of frequencies. The carrier wave is modulated with the pseudo-random pattern of pulses, and the resulting modulated carrier wave passed through both a filter (30) and an attenuator (32) to suppress any discernible feature or signal characteristics of the resulting waveform. The modulated carrier is transmitted by an antenna (42) and a received return signal is processed by a signal processor (100) to obtain pertinent information about a target. The transmitted waveform has no discernible attributes by which the waveform, if processed and analyzed by someone else's radar detector (E) would convey any intelligence as to the presence or source of the transmitted waveform.

Title: Improved method for collision management in a non-contact data exchange system
Inventor: GRIEU FRANCOIS
IPC: G06K17/00
Filed: 1999-01-15
Granted: 2007-09-25
Abstract: The invention relates to a method for managing collisions in a data exchange system between portable objects and at least one send-receive terminal capable of cooperating with a plurality of said portable objects which are simultaneously present in the communications field of the terminal. The method consists of the following steps: a) transmission of call messages by the terminal to the portable objects; b) conditional transmission from the portable object to the terminal of a response message to the call message with a probability of possibly less than 100 %, where the response message contains an identification code specific to the portable object; c) when the terminal receives a response from an identified portable object and if said response does not collide with the response sent by another portable object, a specific data communication link is established between the terminal and identified portable object, data are exchanged and the process returns to step a) for a further iteration; and d) if there is no reception without collision, return to step a) for a further iteration. According to the invention, terminal transmissions comprise two types of call messages: query messages, which initialise the probability of response by the portable objects, and marker messages sent out in succession after query messages. The marker messages are able to instruct the portable objects to adjust the probability value on reception of a marker message in the absence of a previous response to a call message.

Title: Apparatus and method for air-in-line detection
Inventor: FARQUHAR ALLEN B
IPC: G01N37/00
Filed: 1998-09-18
Granted: 2007-07-31
Abstract: The concentration of air or other agents in a fluid delivery line is determined by monitoring agent signals and processing those agent signals along with information regarding the age of each agent signal. The processor determines a primary agent concentration value based on the received agent signal values, with the primary agent concentration value determined by giving greater weight to more recent agent signal values. Where the primary agent concentration value exceeds a primary threshold value, an alarm signal may be activated. The processor also may determine a secondary agent concentration value, which may be determined from the actual agent signal values instead of the weighted agent signal values. Where the secondary agent concentration value exceeds a secondary threshold value, an alarm signal may be activated.

Abstract: Duplicate processing at network operators is avoided by applying once-only processing at operators which are adjacent to either the source or destination host of a data packet. An operator is adjacent to a host if there exists a path between the operator and the host containing no other operators. In one embodiment, an operator determines that it is adjacent to a host if it receives a special broadcast data packet from the host. To ensure that no other operators receive the special broadcast data packet, the adjacent operator drops the packet. In another embodiment, operators determine whether they are adjacent to identified hosts by transmitting special ping packets to the hosts. If an operator receives a ping response from the host, the operator determines that it is adjacent to the host. To ensure that only adjacent operators receive ping responses, intervening operators drop special ping packets received from other operators.
