Patent CA-2760247-A1 (CA)
Title: Method and apparatus for achieving higher thermal efficiency in a steam engine or steam expander
Inventor: PEOPLES JERRY A
IPC: F01L35/04
Filed: 2011-12-02
Abstract: A high order of thermal efficiency is achieved in a steam engine or expander having a piston clearance that approximates zero together with a negligible amount of compression, such that pressure in the clearance volume approximates ambient pressure. i.e. atmospheric or condenser pressure as the case may be at the end of the piston return stroke when the clearance is essentially zero. These two provisions working together simultaneously provide a method and apparatus which constitute a new engine apparatus and Rankine operating cycle that can be referred to as "zero clearance with zero compression". The invention also provides an improved steam admission valve assembly that can be operated either automatically responsive to piston movement or by means of a cam shaft and cam or electrically by means of a solenoid that provides an intermittent magnetic field for operating one or more valves. A biphasic exhaust system is described in which a piston operated valve opens to exhaust steam in a primary phase at or near maximum displacement, and in a secondary phase an auxiliary, normally open exhaust valve facing the top of the piston permits virtually all residual steam to be exhausted through the approximate end of the piston return stroke after which it is closed by the piston, by a lifter on the piston or by the cam and finally held closed during the power stroke by a fresh charge of steam injected through the steam admission valve into the clearance volume as it approaches zero.

Title: Washing apparatus with interchangeable washing methods
Inventor: HASHIMOTO HIDEO
IPC: D06F23/02
Filed: 2011-07-20
Abstract: A washing apparatus is provided with a washing tub whose rotating axis is in a horizontal direction or in a horizontally inclined direction, and has a concave and convex curve surface installed on an inside wall surface of the washing tub as well as has a baffle protruding in the direction of the rotating axis installed. Then, by rotating the washing tub with a level of a cleaning liquid to be supplied to the washing tub set to be higher than the rotating axis, a spurious non-gravity wash method is adopted in which damage to a washing article is small. In addition, by rotating the washing tub with the level of the cleaning liquid to be supplied to the washing tub set to be lower than the rotating axis, a beat wash method in which water saving effect is high is adopted.

Abstract: This is an improvement to plastic bottles by dividing the bottle into two separate but equal halves. Each compartment will feature a different flavour that with the use of the triple twist cap can mixed together to create yet another flavour.  This plastic cap will have the ability to twist from one flavour to another and the added ability to combine both flavours. This design could apply to many different shape and size bottles appealing to consumers need for variety. This could conceivably be carried out in a metal bottle. The plastic lining separates the two flavours and the removable triple twist cap would work well with sports bottles and flavoured water. This product is meant to provide a unique creative twist on the existing market.

Title: Trusted query system and method
Inventor: BOURDONCLE FRANCOIS
IPC: G06F17/30
Filed: 2010-08-26
Abstract: A method and system provides a search interface that permits a user to interrogate a structured database, and includes retrieving database entries from one or more databases, flattening a plurality of database entries, indexing the plurality of flattened database entries to form a search engine index, and prompting the user to enter an input. The system continuously monitors the user input and each time an input is entered by the user, the system computes a set of non-null partial queries in response to the input entered by the user, associates a structured item to each non-null partial query, and allows the user to select one of the structured items. If the user selects one of the structured items, the system replaces the user input by the non-null partial query associated to the selected structured item. When the user validates the input, the system executes the input as a query. Finally, the system provides documents to the user corresponding to the executed query.

Abstract: An apparatus and method for providing cosmetic treatment to skin comprise one material chemically active in a solid form preferably in a tablet form and a second material which is chemically reactive with the first material so that effervescence is produced during the reaction.  The chemically active materials may be activated by a user for providing cosmetic treatment to skin. The activation releases effervescence which urges granules of the reacting materials onto the skin. The size of the granules lowers during the reaction thus providing continuously refining peeling to the skin.

Abstract: The technology described herein provides an active driver control system. Additionally, in various example embodiments, this technology provides methods for optimizing fuel economy (or energy consumption) through active compensation of driver controlled inputs. The active compensation functionality is used to moderate 'sweet spot' vehicle response with driver desired performance. In particular, the active compensation functionality can be used to smooth the vehicle response and attenuate undesired frequency content from the driver input. One of the benefits to this technology is that it assists all drivers in achieving better fuel economy in real world driving. Another benefit is that active compensation of driver controlled inputs can mitigate some of the negative effects of more aggressive driving styles. In addition to active compensation functionality, the technology described herein is also capable of generating a Green Driver Index which is derived by quantifying the driver's control ability and normalizing the result against desired fuel economy and performance targets.

Title: Fauteuil de jardin toute saison
Inventor: LAMBERT NORMAND G
IPC: A47C1/02
Filed: 2012-08-28
Abstract: Un fauteuil qui permet de s'asseoir confortablement dans un jardin extérieur, en toute saison, entouré d'air dont la température est contrôlée. Ce fauteuil est branché à une soufflerie conventionnelle munie d'un filtre et dont la température de l'air est contrôlée. L'air provenant de la soufflerie pénètre dans une enceinte dont la paroi supérieure est le fond d'une chaise longue. La chaise longue prend ainsi la température de l'air provenant de la soufflerie. La majorité de l'air sort de l'enceinte par une fente continue qui entoure complètement la chaise longue. La fente est en angle calculé et, cette façon d'orienter l'air forme un dôme d'air à température contrôlée au-dessus de l'utilisateur du fauteuil. Ce dernier bénéficie ainsi de la température de la chaise longue et de la température du dôme d'air qui l'entoure. Pour éviter que l'utilisateur du fauteuil dérange le jet d'air continu qui sort de la fente, la chaise longue est légèrement enfoncée dans l'enceinte et le jet continu d'air sort tout autour de la chaise longue au sommet du pare-brise partiel que forme cet enfoncement. De plus, la vélocité du jet d'air continu sortant de la fente empêche les moustiques d'atteindre l'utilisateur du fauteuil lors de son usage durant les saisons plus chaudes.

Abstract: A process for water treatment, including a combination of methods from the group comprising coagulation, sedimentation, flocculation and ballast flocculation, which is further improved by the addition of a simplified sludge recirculation system. The recirculation system corresponding to this process allows higher sludge density as well as less significant water volume losses by making the sludge accumulating at the bottom of the sedimentation zone go through a hydro cyclone a certain number of times in repeated cycles thus augmenting the solid particles density of the extracted sludge. The system may also be controlled by a suspended solid analyser, a flow meter and/or a timer. The present invention also includes a method of producing specific fluid flow control behaviour with this simplified sludge recirculation system, which furthermore improves the efficiency of the process.
