A composition such as a water-based consumer product comprises material (e.g. perfume) encapsulated within shell capsules, each capsule comprising an encapsulating wall having an inner surface and an outer surface, with a coating on the inner surface and/or outer surface of the shell wall, the composition further comprising surfactant and/or solvent. The coating can improve the barrier properties of the shell and can enhance retention of the encapsulated materials within the shell.

The present invention is a rotary device that may be adapted for use as a propeller assembly and electrical generator for aerial vehicles or other vehicles intended for fluid media. In one example, the device includes a ring assembly having a plurality of centrally linked blades coupled to a rotatable common hub. Rotary motion of the ring assembly is facilitated by coupling it to an opposed cylinder, opposed piston, internal combustion. The ring assembly includes components of an electrical power generating system so that electrical power is produced from the rotation of the ring assembly.

The present invention relates to a liquid cooling assembly for cooling electronic components. The liquid cooling assembly contains a heat spreader plate rigidly coupled to a structural foam layer for providing mechanical support and thermal dissipation for the electronic components. A fluid channel, rigidly coupled to the structural foam, is provided for directing a cooling fluid in the plane of the heat spreader and a bottom plate rigidly coupled to the structural foam to protect the electronic components against one or more destructive shock events and to provide thermal dissipation of heat generated by the electronic components. The present invention also provides a maze structure in the liquid cooling assembly to increase structural stability against destructive shock events. The present invention relates to a ruggedized electronics enclosure for housing electronic components containing a top compartment configured to house the electronic components. The top compartment contains a first electronics layer and a second electronics layer adjacent to said first electronics layer and a cooling assembly, rigidly coupled to the top compartment. A thermal shunt is configured to channel heat from the first and second electronics layers to the cooling assembly and to provide additional mechanical support to protect against potentially destructive shock events.

The invention relates to a method for preparing propylene from methanol, which mainly solves problems of the prior art, such as low weight ratio of propylene/ethylene and low propylene selectivity. The invention solves the problems by using the methanol/water mixing liquid as material, contacting the material with a catalyst under conditions of 400-550 DEG C, 0.1-1Mpa, 1-5 hour<-1> of methanol weight hourly space velocity and 0.2-5:1 of water/methanol weight ratio, reacting and generating an effluent containing propylene, wherein the catalyst contains following componets by weight percent: a) 0-10% P of P2O5; b) 0-10% Mg of MgO; c) 0-10% La of La2O3; d) and the rest ZSM-5 molecular sieve, wherein the dosage of a, b, and c can not be zero at the same time. Thereby, the invention is useful in industrial production of propylene from methanol.

A high production net shape filament winding manufacturing process and resulting products are disclosed. The manufacture of bicycle frame and their components from filament wound components which have been cut from a section of filament wound stock is disclosed. Also disclosed is a bicycle frame and its manufacturing process and a composite bicycle fork and components thereof.

A water-based surface-treating agent for metallic materials which gives a film highly satisfactory in corrosion resistance, blackening resistance, wet secondary adhesion to topcoatings, low-pollution characteristics (amount of fixed chromium), chemical resistance (especially acid resistance and alkali resistance), etc., while retaining the intact practical liquid stability of conventional chromate-containing resinous coating agents. The water-based surface-treating agent comprises a synthetic resin emulsion and hexavalent chromium ions and has a pH of 5 or lower, the synthetic resin emulsion being one obtained by emulsion-polymerizing the following ingredients using a nonionic polymerizable emulsifier and a nonionic nonpolymerizable emulsifier: (1) an ethylenic carboxylic acid, (2) a functional acrylic monomer having at least one of N-((un)substituted methylol)carbamoyl, phosphonate, alkoxy, cyano, and carbamoyl groups, and (3) a third monomer which is different from the ingredients (1) and (2) and forms the skeleton of the copolymer to be obtained.

An improved quick change power tool chuck is provided which is principally used on a wood working router but could also be used in many other power tool applications. The key features of the quick change chuck are the unique way that it secures the cutting bit from unwanted slippage, the large mechanical advantage thereof and the speed in which a cutting bit can be removed and replaced. The chuck can be aligned and attached to the power tool in the same manner that a standard collet is aligned and attached to the router spindle.

A method is disclosed utilizing off the shelf constant cross section thickness sandwich panels comprised of Fiber Reinforced Thermoplastic (FRTP) resin skins and low density thermoplastic (TP) core material wherein the steps of selectively and controllably exposing the panels to heat and incrementally thermoforming the skin-core into a consolidated composite edge or intra-panel area in consideration of subsequent mating and attachment of the FRTP sandwich panel to other structures is achieved. The exact configuration of articles so thermoformed is design optimized to overcome manufacturing, assembly, weight, in-service and structural performance shortcomings of prior art and FRP sandwich panel structures. Further disclosed is an improved, load-bearing, modular design container structure assembled from such thermoformed FRTP sandwich panels in which is utilized the unique core-skin edge configuration of the present invention in consideration of improved: load bearing performance, useful load volume, reduced manufacturing costs, structural weight savings, impact and damage tolerance and repair and replace issues.

A combustible fluid operated engine free of lost momentum during piston reciprocation has respective series of cylinders and pistons on counter-rotating carrier wheels. Fuel is injected into the cylinders from the pistons. The carrier wheels are variably spaced relatively to vary the combustible fuel compression. The power output is variable.

A brushless can motor includes a motor shaft, a rotor fixed to the motor shaft, a first end cap on which a first end of the motor shaft is rotatably supported, a second end cap on which a second end of the motor shaft is rotatably supported, and a stator placed between the first end cap and the second end cap along a longitudinal direction of the brushless motor. The rotor includes a plurality of magnets. The stator is configured with a plurality of windings adapted to connect to an external motor controller. The first end cap, the second end cap, and the stator are all formed in substantially cylindrical shape, such that said brushless motor, in its assembled form, has a substantially can shape.
