Abstract: A motor is disposed above the protective covering or chassis of a movable surface treatment device. Via its vertically arranged power take-off shaft, the motor drives the horizontally extending rotor shafts, on which respectively one rotor cage is disposed on both sides of a gear housing. The rotor shafts are driven in opposite directions, so that one drum mills in the same direction and the other drum mills with opposite horizontal rotary movement. The gear housing is driven in a stepped-down manner via a two-stage transmission by a power take-off pulley disposed on the power take-off shaft. The rotor cages make two superimposed rotary movements. Thus, the treated surface no longer has a grooved appearance, the surface is treated more evenly and better, and finally, no self-driving force acts on the movable surface treatment device. Work safety is thus increased in addition to work quality One rotor cage is driven in the same direction, the other in the opposite direction with respect to the horizontal rotation, by which the work output is increased and the appearance of shadows is removed.

Abstract: An oil filter (10) utilizes a thermoplastic material (22) having oil oxidation and acidification ar-resting additives mounted in a cas-ing (11) between particulate filter-ing material (19) and a felt pad (21). The thermoplastic mate-rial is desirably high molecular weight polypropylene in the form of rice-shaped pellets, or spaghetti-shaped strands. The additives in-clude about 10-17 weight % of the thermoplastic  material/additive combination, and as the thermo-plastic material is dissolved by the above ambient temperature oil, the additives are released. The thermoplastic material pellets or strands are formed by mixing anti-oxidation and anti-acidification ad-ditives with liquid thermoplastic material to form a mixture, ex-truding the mixture into spaghetti-like strands having a thickness of about .0625-.125 inches, cooling the strands, cutting the strands into discrete elements, and then plac-ing the discrete elements into an oil filter held in place to contact oil to gradually dissolve to release the additives.

Abstract: The present invention provides methods and apparatus for freeze drying in which a solution, which can be a radioactive salt dissolved within an acid, is frozen into a solid on vertical plates provided within a freeze drying chamber. The solid is sublimated into vapor and condensed in a cold condenser positioned above the freeze drying chamber and connected thereto by a conduit. The vertical positioning of the cold condenser relative to the freeze dryer helps to help prevent substances such as radioactive materials separated from the solution from contaminating the cold condenser. Additionally, the system can be charged with an inert gas to produce a down rush of gas into the freeze drying chamber to also help prevent such substances from contaminating the cold condenser.

Abstract: La présente invention concerne un procédé de traitement cryogénique d'une lésion (20), qui comprend les étapes suivantes: appliquer un liquide fluorochimique à la lésion (20), placer au moins une cryosonde (26) dans la lésion (20) et faire circuler un fluide cryogénique, qui provoque la formation d'une boule de glace (30) autour de la cryosonde (26), cette boule de glace détruisant au moins en partie la lésion (20). Le liquide fluorochimique, qui sert à renforcer le processus chryochirurgical, est perfusé ou injecté dans et/ou autour de l'emplacement de la lésion, avant et/ou pendant l'application d'une cryosonde (26) à l'emplacement de la lésion. Dans une forme d'exécution de l'invention, le liquide fluorochimique agit en tant que produit de contraste afin d'améliorer l'imagerie médicale en temps réel de la zone contenant la lésion, tout en modifiant le milieu à l'intérieur et autour de la zone contenant la lésion. Dans une autre forme d'exécution de l'invention, le liquide fluorochimique renforce les processus chryochirurgicaux en contrôlant la taille et la forme des boules de glace (30) constituées au cours desdits processus. Dans cette forme d'exécution, on utilise un liquide fluorochimique dont la conductivité thermique et le point de congélation auront été correctement choisis. En fonction des propriétés thermiques retenues, deux cas de figure se présentent: soit le liquide facilite la congélation de la zone visée et/ou favorise la conduction thermique en vue de la congélation de zones plus importantes, soit il limite la congélation de la zone visée et réduit la conduction thermique. Dans une forme d'exécution sans cryosonde, la liquide est refroidi à une température inférieure au point de congélation du tissu biologique. Le liquide refroidi est ensuite injecté dans la lésion kystique ou autour, entraînant ainsi son ablation.

Title: Digitally removing video copy protection pulses
Inventor: QUAN RONALD
IPC: H04N7/171
Filed: 1996-10-17
Granted: 2001-07-31
Abstract: The invention uses digital techniques for defeating the effects of the analog copy protected signal while the signal is in the digital domain. The types of copy protection signals includes pseudo sync pulses and AGC pulses. Additionally digital techniques may be used for reducing or eliminating the effects of a chroma copy protection process (Figs. 10-14). A digital video copy protection eliminator allows removal of substantially all pseudo sync pulses and/or AGC pulses in the digital domain. The location of pseudo syncs and/or AGC pulses are determined, while the signal is in the digital domain. These known pixel locations of all or some of the pseudo syncs and/or AGC pulses are used to digitally modify the signal so as to effectively remove the pseudo sync pulses and/or AGC pulses.

Abstract: An apparatus has servo motors used for driving sources in processes of weighing blended resin, of injecting weighed resin into a die cavity, of opening and closing dies, of gate cutting after filling weighed resin into the die cavity, of ejecting the molding after forming, and of removing the molding.    According to this configuration, because all the motions of injection operation are controlled by servo motors, the timing, injection speed, pressurizing speed, pressurizing pressure, and all others can be freely controlled, and not only the transferability of fine protrusions and recessions formed on the inner surface of the die cavity can be remarkably improved, but also the cycles can be increased because complex motions can be carried out by servo motors.     In particular, because servo motors are used for driving sources of ejection of molding after forming and removal of molding, there is no variation in repetitive response accuracy in motion, product removal timing by the product removing equipment can be reduced to 0.01 second or less, and ultimately higher cycle is able to be achieved.
