Title: Package having a dual-film lid comprising a gas-impermeable film and a delaminatable, gas-permeable film
Inventor: KOCHER PATRICK N
IPC: B32B27/08
Filed: 1997-11-24
Abstract: A dual-film package and method for making such package is disclosed which combines the manufacturing simplicity of a package having a single, peelable lid with the consistent peelability of a package having separate permeable and impermeable lids. This is accomplished by providing a support member (12) and a lid (24) having a gas-permeable film (26) and a substantially gas-impermeable film (28). A first heat-weld (30) bonds the gas-permeable film to the support member and a second heat-weld (32) bonds the gas-impermeable film to the gas-permeable film. The first and second heat-welds each have a bond-strength which is greater than the intra-film cohesive strength of the gas-permeable film so that the lid preferentially delaminates within the gas-permeable film upon peeling, thereby leaving a portion of the gas-permeable film lidded to the support member.

Abstract: A temperature stabilized tapered fiber optic component is produced, such as a fiber optic coupler or a fiber optic filter. In the case of the component such as a coupler, at least two fibers are fused and tapered to achieve a desired taper profile with suitable mechanical and wavelength properties. In the case of a component such as a fiber filter, only one fiber is tapered. Once the component is formed, it is solidly secured to a rigid substrate that produces a mechanical stress such as to compensate for any modal phase shift of the component due to temperature variation. Also, the mechanical phase dependence of the component may be adjusted in relation to the substrate to provide the desired temperature compensating effect. Preferably, both these features are used to achieve the best possible temperature stabilization.

IPC: B03B9/06
Filed: 1998-03-18
Abstract: A method and apparatus for separating the membrane portion of waste egg shells from the hard mineral portion thereof, so that each can be used or further processed as described, thereby addressing the environmental and economic issues associated with disposing of waste egg shells. The membrane and shell are separated by first processing waste egg shells so as to yield small waste egg shell particles. During this processing, the waste egg shell particles are at least slightly abraded, whereby the linking structure between the membrane and shell is at least partially disrupted. Thereafter, the waste shell egg particles are conveyed to a tank (102) containing, preferably, water, and allowed to settle therethrough. As the waste egg shell particles settle, the particles experience turbulent forces in the liquid which cause the membrane and shell portions to fully separate.

Patent CA-2291935-A1 (CA)
Inventor: ROY JAMES
IPC: H02J7/00
Filed: 1999-12-08
Abstract: A battery charger system providing increased reliability over conventional chargers includes one or more charging modules coupled to a central controller module. Each charging module is capable of charging one or two batteries and includes control logic that controls the charging current provided to each battery. Each charging module is capable of charging the associated batteries using a pre-programmed, selectable charging protocol. The control logic included in each of the charging module provides a "first level of intelligence" for charging batteries. The controller module provides a "second level of intelligence" that generally operates in conjunction with the first level of intelligence provided by the charging modules. The second level of intelligence provided by the controller module individually enables and disables charging to a particular battery by an associated charging module. The charging modules are capable of charging batteries even without control from the second level of intelligence. Thus, reliability is increased by being able to continue battery charging even if the controller module fails or is removed from the battery charging system. Other features such as the lack of battery voltage sense lines removes the possibility of failure due to faulty or damaged sense lines, thereby increasing reliability.
