Patent CA-2418643-A1 (CA)
Title: Screw-top bottle liquid dispenser
Inventor: ATANASOAIE NECULAI
IPC: B65D47/24
Filed: 2003-02-11
Abstract: This device's general purpose is to seal screw-top bottles of any material, in order to keep the carbonation of a liquid to a maximum. While the proper working ability of the device is solely dependent on the pressure within the sealed bottle, the device can be depressed to allow the forces of the pressure built-up by the carbon dioxide within the liquid tube, which extends down to the bottom of the bottle.   When the device is depressed, the pressure within the bottle pushes the liquid up the tube and out of the spout.

IPC: F25D3/10
Filed: 2001-08-15
Abstract: The inventive method and device are used for systems for reducing gas pressure in a well or a main pipe-line to the gas pressure required by a customer. A  known method for utilising the energy of a gas during a reduction of the pressure thereof from the high pressure, for instance a pressure in the main pipe-line, to the required pressure is carried out by converting the energy of a gas expansion into mechanical energy using the pressure of the liquefied cooled gas as a coolant. The novelty of the inventive method lies in the multiple reduction of the gas pressure and in a multiple extraction of the cold thus produced. The inventive device is characterised in that the input thereof is connected to well or a main pipe-line (3) having a high pressure, and the output is connected to the pipe-line having a low pressure or to the customers (7, 9) with the low pressure. Said device comprises a gas expansion engine (for example, a gas expansion turbine) embodied in two parts (1, 2) which are arranged successively in the direction of the pressure reduction, a mechanical energy conversion device (4) which is kinematically connected to the gas expansion engine, for example an electric generator, and also two or more heat exchangers.

Abstract: L'invention concerne des procédés d'accord, de commutation ou de modulation, ou, en général, de modification de la résonance de micro-résonateurs à guide d'onde. Les modifications de la résonance peuvent être obtenues, de manière permanente ou temporaire, par une modification précise de la dimension du micro-résonateur, par une modification de la structure physique locale du dispositif ou par une modification des indices de réfraction effectifs et de groupe du mode du micro-résonateur. Le changement d'asymétrie du profil de l'indice autour d'un guide d'onde peut modifier la biréfringence du guide d'onde et permet de régler la polarisation dans le guide d'onde. Ce changement de profil d'indice peut être utilisé pour modifier la dépendance à la polarisation ou la biréfringence des résonateurs.

Inventor: YEOLA SARITA W
IPC: A61P25/28
Filed: 2001-10-12
Abstract: The present invention describes calcium sensitive and selective maxi-K  potassium channel opener/activator compounds that function to open maxi-K  channels under conditions of high intracellular calcium concentrations, and which do not significantly affect the opening of maxi-K channel proteins under conditions of low or physiologically normal intracellular calcium concentrations. Methods of assaying for and using such compounds are also provided. According to the invention, whole cell voltage patch-clamp studies newly demonstrated that the ability of opener compounds, e.g., fluoro-oxindoles and chloro-oxindoles, to open maxi-K channels was sensitive to the intracellular ca2+ concentration ([Ca2+])i, i.e. more channels opened at more negative potentials. Particular fluoro-oxindole and chloro-oxindole compounds produced significant increases in whole-cell maxi-K potassium channel-mediated outward currently only in cells having higher [Ca2+]i, compared with effects in lower [Ca2+]i. Such compounds provide Ca2+-sensitive and selective openers of maxi-K channels which show maximum effectiveness under conditions of increased [Ca2+]i and, as such, provide treatments for diseases and disorders in which cells undergo, or are subject to, traumatic stress due to high internal calcium levels, such as stroke.

Title: Apparatus for simulating a ski slope
Inventor: SHOWAN JONATHAN MARK BURLING
IPC: A63B22/02
Filed: 2000-10-20
Abstract: A ski slope simulator has a ski deck (12) with a surface defined by a continuous belt of material formed in a closed loop around rollers at the front and back of the ski deck. The belt is driven so that the surface of th e ski deck rides up the slope. The angle of inclination of the deck and the drive speed are controllable. A handrail (24) is provided towards the front of the deck, and the angles of inclination of the handrail (24) with respect to  the base (18) (i.e. the floor) and with respect to the surface (12) vary as the angle of inclination of the deck is varied. This arrangement of the handrail can be configured such that the natural position of the skier on th e ski deck when holding the handrail remains substantially fixed as the angle of inclination of the ski deck is varied. In this way, the area of the ski deck  can be minimised because the user remains substantially static with respect to the ski deck.
