Abstract: Il est possible de mélanger un polyamide à terminaison ester, de faible poids moléculaire, à un hydrocarbure liquide en vue de la formation d'une composition transparente possédant la consistance d'un gel. On prépare ledit polyamide à terminaison ester en faisant réagir "x" équivalents d'acide dicarboxylique, 50 % au moins de ces équivalents provenant d'acide gras polymérisé, "y" équivalents de diamine du type éthylènediamine, et "z" équivalents de monoalcool possédant au moins 4 atomes de carbone. La stoechiométrie du mélange réactionnel satisfait les relations: 0,9 < [x/(y+z)] < 1,1 et 0,1 < [(y+z)] < 0,7. On chauffe les réactifs jusqu'à ce qu'ils atteignent l'équilibre réactionnel. Ledit gel (Fig.1) contient environ de 5 à 50 % de polyamide à terminaison ester, le reste étant de préférence constitué d'hydrocarbure pur. Ces gels sont utiles à la formulation de produits de soins personnels et d'autres articles qui doivent présenter, de préférence, une certaine consistance ou l'aspect d'un gel.

Granted: 2006-04-04
Abstract: The invention provides an apparatus for piercing the cap of a container. The apparatus includes a blade support arm slidably attached to one or mare vertical posts, a blade attached vertically below the blade support arm, and a cap retainer arm slidably attached to the vertical post such that the cap retainer arm is capable of travel along the posts between an upper position wherein the cap contacting surface is located above the elevation of the container cap and a lower position wherein the cap contacting surface is located at the elevation of the container cap. The cap retainer arm has an opening through which the blade can pass. A biasing member biases the cap retainer arm towards its lower position. The cap retainer arm is positioned below the blade but above the blade support arm contact surface. Thus, when the blade support arm slides upwardly, the blade support arm contacts the cap retainer arm and pushes the cap retainer arm upwardly from its lower position to its upper position.

Abstract: A variable velocity open transmission line (507) comprises a central conductor means (1100) having a permeable central element (1202) carrying a helically wound conductor (1201). The inductance of the central conductor, and hence the propagation rate of the line, is varied by means of a periodically varying signal (V m) applied to the helically wound conductor. When the open transmission line is used in an intrusion detections system, an intruder traversing the line causes different phase variations at the different propagation rates. A processor compares these phase variations to locate the entity.

Abstract: A method for obtaining a report from a mobile station on the status of frames comprising an entire message transmitted to the mobile station is disclosed. First, a polling request is sent to the mobile station from a base station. A status report is then sent to the base station. The polling request specifies whether the mobile station should send the status report on a reservation basis (using a reserved frame) or on a contention basis (using an idle frame). The mobile station then transmits a bit map to the communication system to indicate which frames have been correctly received by the mobile station at the point when it received the polling request.

Abstract: A vacuum-assisted venous drainage reservoir of cardiopulmonary bypass surgery with both hard and soft shell reservoirs. The system creates regulated negative pressure of approximately -70 to -25 mmHg within a sealed hard shell reservoir, or within a sealed housing surrounding a soft shell reservoir. The reservoir has a blood inlet for supplying blood removed from the patient and a blood outlet leading to an oxygenator. A vacuum regulator subassembly for manually setting the predetermined desired vacuum, a valve subassembly for manually enabling and disabling the negative pressure, a pressure relief valve, and/or a vacuum stabilizer to reduce the severity of large changes in vacuum pressure may be provided. A flexible membrane in the hard shell reservoir may expand to contact the blood surface and reduce blood/air interactions. A volume sensor for the hard shell reservoir may be used in a feedback loop for controlling the vacuum, circulation pump, or other device. A piece of air-permeable in the venous return line enables the use of smaller cannulas suitable for minimally invasive surgery. The reservoir need not be positioned well below the patient as in conventional gravity venous drainage configurations, thus adding flexibility to the operation room layout and enabling areduction in the required extracorporeal blood prime volume.

Abstract: An AAA receiving circuit 105 calculates reception weight of signals received by adaptive array antennas 101, and a direction of arrival estimating circuit 106 estimates a direction of arrival of the received signals.      A demodulating circuit demodulates the received signals to separate transmission power control information. A radiation pattern calculating circuit 108 calculates directional gains based on the reception weight and the arrival direction of the received signals. A gain controlling circuit 109 calculates a correction value based on the directional gains and transmission power control information, and controls a gain of a transmission power amplifier. A transmission weight calculating circuit calculates transmission weight based on the reception weight and the correction value.      This makes it possible to control transmission power such that reception power of each communication counterpart becomes constant, and to improve communication quality and an increase in the number of containable users in a system wherein directivity is sequentially changed in accordance with the positions of the communication counterparts or a propagation environment.

Title: Hydro massage bathtub with light and ozone treatment
Inventor: JACQUES MARC
IPC: A61H33/02
Filed: 2000-04-18
Granted: 2004-01-27
Abstract: A hydro massaging tub is used for massage treatment wherein the treatment is performed by ozone-mixed warm air or water jets distributed adjacent the bottom wall of the tub all about its circumference.      Ozone generated by an ozone generator is injected in an air distribution duct to sterilize the air distribution system and help clean the skin of the bather's body. The oxygen liberated in the water and the air improves the quantity of oxygen in the bather's environment so that oxygen intake through the skin and lungs is facilitated.     A mobile air jet and section control of the air jets enable the bather to massage selective body areas with adjustable intensity of sections of the massage to achieve a desired effect. In one embodiment, orientable valves are mounted in the air jet holes for adjusting the orientation of the air jets. In another embodiment, optical fibers or light emitting diodes are provided to emit light frequencies in the water turbulence for physiological and therapeutic effects. The air distribution system may be made from material treated with antibacterial agents to maintain a clean condition and ensure the bather's health.
