Title: Container with pressure compensation holes
Inventor: KNEER ROLAND
IPC: B65D83/00
Filed: 1997-06-27
Abstract: A container is produced by a coextrusion blowing process and contains a stiff outer container (6) and an easily deformable inner bag (7) made of different types of thermoplastic materials which cannot be welded together.

Title: Impulse radar guidance apparatus and method for use with guided projectiles
Inventor: SMALL JAMES G
IPC: F41G7/30
Filed: 1998-09-22
Abstract: An impulse radar guidance system (10) and method (30) for use with a spinning projectile (11). The system and method tracks the flight of the spinning projectile using an all-weather radar (14) or tracker (14). A linearly polarized asymmetric waveform (21) is transmitted at the projectile that comprises a series of repeating pulses (22) having a relatively strong, short, positive electric field pulse (23) followed by a relatively weak, long, negative electric-field baseline (24). The projectile contains a dipole antenna (26) having a switching diode (27) disposed between respective halves thereof. The waveform is reflected from the antenna which spins with the projectile and reflects a relatively strong signal when the electric field pulse of the asymmetric waveform is aligned along a conduction direction of the diode, a relatively weak reflected signal when the antenna and diode are aligned orthogonal to the electric field pulse, and a small, non-zero, signal when the diode is aligned anti-parallel to the electric field pulse and the diode is back-biased so that respective halves of the antenna are disconnected. The radar or tracker measures the instantaneous roll angle of the spinning projectile during its flight as a function of the state of the reflected signal. The projectile has a maneuvering device (16), and a receiver (15) that receives commands that causes the maneuvering device to actuate at one or more specific roll-angles to deflect the flight direction of the projectile at a target.

Title: Microwave-assisted liposuction apparatus
Inventor: MASSENGILL R KEMP
IPC: A61M1/00
Filed: 1998-04-08
Abstract: A method and apparatus for heating fatty tissue to facilitate liposuction removal of fat, and by additional heating to enable denaturing of the tissue structure. The apparatus uses microwave energy, applied by a cannula (16) to the fatty tissue, as a means to facilitate fat removal. The microwave energy is delivered at a frequency range chosen to optimize energy coupling directly to the fatty tissue, while insuring the attenuation of the radiation level to a safe level in a relatively short distance. The cannula (16) is provided with internal channels to simultaneously provide fluid and remove the mixture of fluid and fatty tissue. Since the microwave frequency is selected to insure direct coupling with the fat tissue, it is not necessary to introduce water to promote coupling, and if water is introduced for cooling or irrigation purposes no salts need to be added to the water for purposes of microwave energy coupling.

Abstract: The invention relates to an ingot arrangement (1) in a continuous casting installation, comprising an ingot mould (2A) and an oscillating holding device (4) used for causing said ingot mould to swing when in a casting position (2a). The ingot arrangement consists, in a separable manner, of an interchangeable part (2a) and a stationary part (4, 11, 12, 12', 71). To replace the interchangeable part, it is separated from the stationary one and moved using a conveying means (23), at least along a partial path, from its position of operation into an area (29) beneath the casting position (2a).  This enables, especially in multiline casting installations, the interchangeable part to be transported during the casting process and, for example, along paths comprising straight (23') or arciform segments (23''), to any purposefully selected position (2b) and to be replaced by a new interchangeable part by reversing the steps of the method. Such a method allows for an interchangeable part to be replaced in multiline installations with no interference with the casting process in any adjacent ingot arrangement.
