Abstract: An auto-retractable pen comprises a pen and a cap. The pen comprises a hollow case, a middle screw piece, an ink cartridge, a mechanical spring and a mobile magnetic element. The cap comprises a cap body and a stationary permanent magnet. The pen is capable of attaching to the cap by the magnetic attraction force in a single-hand operation when a user places the mobile magnetic element of the pen in proximity to the stationary permanent magnet of the cap. The writing tip of the pen retracts into the hollow case of the pen when an upward magnetic attraction force becomes greater than a downward mechanical expansion force. The middle screw piece is capable of adjusting the strength of the cushion effect by the mechanical spring according to Hooke's Law. This invention relates to retractable pens, and the principal use of the invention is for operating a pen with a single hand.

Abstract: L'invention concerne un procédé dans lequel est utilisé un système à deux colonnes pour la récupération de propane et de composants plus lourds à partir d'un flux gazeux d'hydrocarbures. Le gaz d'alimentation est refroidi, partiellement condensé, puis séparé afin d'obtenir une premier flux liquide et un premier flux de vapeur. Le premier flux liquide est dirigé vers une colonne de distillation récupérant dans sa partie inférieure une majeure partie de propane et de composants plus lourds, et générant un flux gazeux de tête de distillation. Le premier flux de vapeur est expansé puis dirigé en tant qu'alimentation de fond vers l'absorbeur. L'absorbeur génère un flux de tête de distillation d'absorbeur contenant essentiellement l'éthane et les composants plus légers, et un flux de fond de l'absorbeur. Le flux de fond de l'absorbeur est chauffé, puis dirigé vers la colonne de distillation en tant qu'alimentation intermédiaire. Le flux de tête de distillation de l'absorbeur est réchauffé et éventuellement comprimé. Une partie du flux comprimé est sensiblement condensée et dirigée vers l'absorbeur en tant qu'alimentation supérieure.

Abstract: A barrier against soiling to the wearer, this functional, easy to use bib comprises a body made of washable, flexible, durable and non-porous material with a front and a back.  The body includes two semi-circular upper sections that protect the wearer's shoulders from soiling while also securing the bib around the wearer's neck. In fastening these upper sections together, a portion of the bib body arcs outwardly to conform to the wearer's upper body. The lower body of the bib forms into a bowed pocket for catching and retaining food particles and liquid thus shielding the user from soiling.  The pocket is formed firstly by folding the lowest portion of the body upwards toward the front of the bib and fastening with corresponding snaps on each side and secondly, by folding the bottom right and left corners of the pocket around to the backside of the bib and fastening to the corresponding snaps on the backside. The pocket unfastens for the purpose of wiping and/or washing once removed from the wearer. The integrity of this pocket to retain liquid and food particles is assured and maintained by the special manner in which it is constructed, folded and fastened; by eliminating any folds within the pocket itself; by eliminating any perforations caused by affixing within said pocket, and by avoiding the use of applied trim along its edges. The resulting bib with an improved pocket prevents soiling to the wearer by catching and retaining a measurable amount of food and liquid debris without leaking and is easy to clean due to the ability to unfasten the pocket.

Title: System for optimizing continuous positive airway pressure for treatment of obstructive sleep apnea
Inventor: RAPOPORT DAVID M
IPC: A61B5/08
Filed: 1995-05-16
Granted: 2010-07-20
Abstract: In the treatment of obstructive sleep apnea, a method and apparatus (70) are disclosed for optimizing the controlled positive pressure to minimize the flow of air from a flow generator (86) while still ensuring that flow limitation in the patient's airway doest not occur. In particular, the invention relates to a breathing device (70) and method of use to adjust a controlled positive pressure to the airway of a patient by detecting flow limitation from analysis of an inspiratory flow waveform. Once the presence of flow limitation has been analyzed the system determined an action to take for adjustment of the controlled positive pressure. The pressure setting is raised, lowered or maintained depending on whether flow limitation has been detected and on the previous actions taken by the system. The preferred breathing apparatus (70) consists of a flow generator (86), a flow sensor (72), an analog to digital converter (78), a microprocessor (80), and a pressure controller (82, 84), a patient supply hose (74), a nasal fitting, and, optionally, a pressure transducer (90). Using the method of the present invention, the microprocessor (80) adjusts the air pressure in the patient's supply hose (74) when flow limitation is detected in the airway of the patient.
