Abstract:

The present invention provides methods and apparatus for separating and/or analyzing fluids of interest. According to principles of the present invention, fluid analysis is accomplished with microfluidic devices and may be reported in real-time or near real-time in a subterranean environment. In addition or alternative to oilfield applications, the principles of the present invention contemplate separation in a laboratory or other environment for biological sample separation and analytical chemistry applications. The present invention is capable of separating liquid-liquid mixtures or emulsions in a microfluidic device without fouling.

Assignee:

Mattel, Inc. - Hawthorne CA

International Classification:

A63H 302
A63H 346

US Classification:

446371

Abstract:

An articulated soft doll construction in which a soft skin covers a soft doll head and a soft skin covers a soft torso in which the head is universally moveable relative to the torso. The torso has a first skin cover covering a fiber filler material. The torso and first skin cover are formed with an opening in which a neck connecting member is received. A second soft skin cover is used to cover a soft head that is filled with fiber material. A neck plug is received through an opening in the head and second soft skin cover. Disposed inside a neck plug is a ball and socket assembly in which the ball is connected to a spindle member that extends into the torso and is received by the neck connecting member for engagement therewith. A collar member is received inside the neck plug for retaining the second soft skin cover around the head. A remaining member is received by the neck connecting member to retain the first soft skin cover.

A63H 3326
G11B 1722

US Classification:

369 31

Abstract:

An electronic toy doll including electronic control circuitry responds to selection of one of a plurality of switches on the doll housing and selects associated vocal messages. The control circuitry includes a stored program of instructions and also permits a problem-solution mode of operation where the user is given a message selected by a weighted probability of the occurrence of a problem and then the doll responds according to how the user correctly or incorrectly responds to the various switch response operations possible.

Assignee:

Mattel, Inc. - Hawthorne CA

International Classification:

F04B 4300
F04B 2102

US Classification:

417479

Abstract:

A pump for use in a doll having a transparent front torso through which is viewed simulated internal organs, the pump being connected to coiled transparent tubing for passage therethrough of a liquid-air mixture. The pump has a main body portion with a generally cylindrical recess having a circular surface with a coaxial annular groove in the surface and an arcuate groove disposed radially outwardly from the annular groove. An inlet aperture is disposed radially outwardly from the annular groove and is in fluid communication therewith while an outlet aperture is in fluid communication with the arcuate groove with the two grooves being interconnected by a groove segment. A one-piece diaphragm is provided with a flange adapted to sealingly engage the surface, the diaphragm having a deformable dome-shaped portion extending outwardly from the surfce to form a chamber, the diaphragm having a skirt portion fitting within the annular groove with the skirt having a cutaway portion in proximity to the groove segment. The diaphragm flange is also provided with a tongue portion arcuate in cross section for abuttingly engaging a surface of the arcuate groove to provide a check valve between the groove segment and the outlet aperture. The skirt portion is so configured within the groove to act as an inlet check valve.

International Classification:

A63H 1300

US Classification:

46119

Abstract:

A figure toy which includes a unique actuating mechanism which cooperates with a novel shoulder assembly which allows the toy to emulate a shrug or a wave and to perform other functions of the same sort in a very realistic manner. The shoulder assembly includes a member which pivots about one end when it receives pressure from the actuating mechanism. The other end of the assembly is attached to an arm. Thus, the motion of the shoulder assembly moves the shoulder upwardly and inwardly simulating very closely the raising of the human shoulder such as occurs during a shrug or a wave. The arrangement allows one or the other or both of the shoulders together to be raised.
