Abstract: A process for producing a polyamide by reacting at least one aminonitrile wi th water has the following steps: (1) at least one aminonitrile is reacted with water at a temperature from 100 to 360 .degree. C and pressure from 0.1 to 35..times. 10 6 Pa, yielding a reaction mixture; (2) the reaction mixture is further reacted at a temperature from 150 to 400 .degree.C and pressure lower than the pressure in step 1. The temperature and pressure are selected to yield a first gaseous phase and a first liquid or solid phase or a mixture of a first solid and a first liquid phase. The first gaseous phase is separated from the first liquid or solid phase or the mixture of a first liquid and a first solid phase is separated; and (3) the first liquid or solid phase or the mixture of a first liquid and first solid phase is mixed with a water-containing gaseous or liquid phase at a temperature from 150 to 360 .degree.C and pressure from 0.1 to 30 .times. 10 6 Pa, yielding a product mixture. Also disclosed are other embodiments of this process and the thus produced polyamides.

Title: Body fluid flow control device
Inventor: SAYET PETER
IPC: A61F2/00
Filed: 1999-03-23
Granted: 2010-02-09
Abstract: An apparatus for controlling fluid flow within a host body has a first shell and a second shell for coupling with the second shell to form a cylindrical object suitable for engaging and surrounding a selected canal with the host body. The cylindrical object is open at both ends and has an interior diameter of a dimension making it suitable for fitting over the selected host body's canal, such as the urethra. The apparatus also includes a plunger for constricting the fluid flow when activated. The plunger may be activated by an electrical solenoid or hydraulic or pneumatic activation to move from a free-flow position into a constricting position wherein the fluid flow through the canal is substantially prevented or reduced. The apparatus can be used for controlling incontinence or restricting fluid flow in other body canals.  The host-user can activate the apparatus with a remote control device outside the body which communicates with the implanted apparatus by means of any wireless communication that transmits a signal to the device causing the solenoid to move the plunger into the constricting position. A second signal causes the plunger to retract into a free-flow position when the user no longer feels the urge to urinate.

Title: Showerhead engine assembly
Inventor: PETROVIC JOHN E
IPC: B05B15/522
Filed: 2000-04-07
Granted: 2006-09-12
Abstract: The showerhead engine assemblies provide different combinations and variations of continuous, deflected, pulsating sprays, and aeration spray patterns including those that are adjustable enabling wide variations in the degree of aeration of the water passing through the showerhead, enabling wide variation of the characteristics of the water spray patterns.  The spray patterns include a nondeflected, nonpulsating spray pattern; a deflected nonpulsating spray pattern; a nondeflected, pulsating spray pattern; and a deflected, pulsating spray pattern, while enabling the engine assembly to be self-cleaning. For pulsating spray modes, the showerhead engine assembly includes but five plastic parts and an O-ring seal; the parts being a stator, a spinner, an engager, a pressure plate, and a faceplate, openings beings disposed in the pressure plate and faceplate to enable fluid flow therefrom. Deflecting surfaces on the faceplate enable a variety of different flow patterns. Spinner rotation starts or stops depending upon the position of the spinner relative to the stator, since the stator includes a pair of stop flanges that engage and disengage with the spinner. When the spinner is disengaged and free to rotate, water flow through passages in the spinner cause spinner rotation, creating a vortex and pulsating spray patterns. The series of showerhead engine assemblies include component parts that are interchangeable, the number of component parts being minimal, the interchangeability reducing the number of spare parts necessary to repair the series of showerhead engine assemblies.

Title: Organoclay/polymer compositions with flame retardant properties
Inventor: ROSS MARK
IPC: C08K3/34
Filed: 2000-06-14
Granted: 2010-08-10
Abstract: The present invention is directed to polymer compositions with flame retardant properties that are made from a polymer blended using a defined process with a smectite clay that has been reacted with a specified mixture of organic materials.      The inventive compositions have the property that when the organically modified clay is added to the polymer, a composite results which has flame-retardant properties and is based on the finding that degree of dispersion of a smectite organoclay in a polymer matrix will give the compositions flame-retardant properties. Further, it has been found that it is very important to proper functioning of the flame retardant polymer compositions that they have the organoclay dispersed in the polymer such that it is not completely exfoliated.

Abstract: A semiconductor structure for use as a laser or amplifier has a multilay er structure including a substrate, an active region, optical confinement and cladding layers on each side of the active region to surround the active region. The structure includes at least one core element at which light emission occurs and interelement regions laterally adjacent to the core element with the effective refractive index of the interelement regions higher than that of the core element to provide antiguiding of light emitted in the core element. The optical confinement and cladding layers on opposite sides of the active region have different indexes of refraction to provide an optical waveguiding structure in the transverse direction in the core elemen t which is asymmetrical and which favors lasing only in the fundamental transverse mode . The structure allows larger core elements to be utilized than otherwise possible and results in a significantly increased light emission spot size enabling much higher emission power levels for lasers and higher saturation power levels for amplifiers.</ SDOAB>
