Patent CA-2215549-C (CA)
Inventor: BERROCAL RAFAEL
IPC: A23C9/146
Filed: 1997-10-01
Granted: 2002-01-15
Abstract: Electrodeionization is used to demineralize milk products and derivatives with cationic ion exchange resins and weakly anionic ion exchange resins in a mixed bed, or with a strongly cationic resin alone in the dilution and concentration compartments if raw materials are treated other than more or less concentrated milk.  In the case where more or less concentrated milk is used as a raw material, the dilution compartments are filled with cationic ion exchange resins and weakly anionic exchange resins in a mixed bed.            The process enables considerable savings to be made in water and energy without using regenerating chemicals.

Title: Absorption over-concentration control
Inventor: MARTINI DAVID MICHAEL
IPC: F25B15/06
Filed: 1997-09-23
Granted: 2000-08-29
Abstract: An over-concentration control system for use with an absorption machine of the type having either a single, double and triple effect cooling and heating cycle, which uses lithium bromide in solution with water as the operating liquid. The operating liquid being characterized by a concentration indicative of the quantity of lithium bromide dissolved in water, and by a phase diagram having a crystallization boundary that defines the combinations of concentration and temperature which correspond to a condition of saturation in the solution. A sensing means is provided at a predetermined location within the system which is responsive to the depth of said solution for generating a concentration signal indicative of the concentration of the liquid. A temperature sensor is also provided for generating a temperature signal indicative of the temperature of the liquid. Further means are provided which are responsive to the temperature signal and the concentration signal for calculating a representation of the absorption cycle of the machine which may be plotted on a phase diagram for the lithium bromide system. The representation includes a plurality of critical state points which are defined by predetermined respectivecombinations of concentration and temperature.  Means are also provided for comparing the actual concentration and temperature of the liquid to concentrations and temperatures which lie on the said crystallization boundary for lithium bromide for generating a difference signal. Control means are provided which are responsive to the magnitude of the difference signal for changing the operating state of said machine as necessary to prevent the liquid from reaching a combination of concentration and temperature that lies on the crystallization boundary.

Title: Method and apparatus for enhancing call set-up and handoff quality
Inventor: GUIMONT VINCENT
IPC: H04W36/08
Filed: 1997-02-26
Granted: 2004-11-23
Abstract: In a cellular telephone system (10), mobile station (16) measurements of received signal strength on each reference frequency are made in order to select a cell (12). At call set-up in or handoff to that cell, a voice frequency is selected (64, 102) by the system to carry the communication. A determination is then made as to whether the antenna used for the reference frequency is the same as that used by the selected voice frequency (66, 104).      From this determination, actions are taken as needed to address concerns over potential differences in broadcast coverage areas for the antennas.      For example, an alternate voice frequency (112) using the same antenna as the reference frequency may be chosen. Further, a test broadcast (120) may be made on the selected voice frequency for comparison to the received signal strength on the reference frequency in order to confirm (126) the selection of the cell and use of the selected voice frequency.

Abstract: For the covering of operation patients it has become customary to use a heat reflecting wrapping sheet for protecting the patients against loss of heat. At the operation area, a hole is cut in this sheet, whereafter the usual, sterile cover sheets (20) are placed around the area (16) and spread over the patient and the table. With the invention it is realised that it is advantageous to combine these sheets, viz. in providing the cover sheets (20) as double layer products with associated, separate and edge connected wrapping sheets (22), whereby the sterile personnel can easily arrange for the required wrapping and at the same time form the opening in the wrapping material with full safety for a correct location thereof. It will then only be required that the wrapping sheets (22) be co-sterilized with the cover sheets.

Abstract: An adaptive, energy absorbing body (10) includes a plurality of fluid filled cells (12) joined together by fluid flow passageways (22) so as to establish an intercommunicating structure which provides effective cushioning. The cells (12) also include pressure responsive seals (30) which restrict fluid flow between the cells (12) and when the cells (12) are subjected to a mechanical force above a preselected level. Closure of the seals (30) converts the material from open cell, to a closed cell structure, allowing it to absorb and dissipate high levels of kinetic energy. The structure is particularly useful as a shock absorbing element for footwear.

Title: An integrated optics chip with reduced thermal errors due to pyroelectric effects
Inventor: ZIMMERMAN GREGORY A
IPC: G02F1/035
Filed: 1999-07-28
Granted: 2008-03-25
Abstract: An Integrated Optics Chip with improved performance when exposed to changing temperature is disclosed. The optic chip or integrated optic chip or MIOC has a top surface, a +Z face and -Z face. The chip is formed from a crystal having a high electro-optic coefficient such as Lithium Niobate. For the purpose of orienting the components to the optic chip to be described, the +Z crystal axis extends outward from the +Z face, the Z axis being the axis across which a pyroelectric effect is exhibited. The top surface is orthogonal to the Z axis. An input waveguide on the top surface receives an optical signal from an input port, passes the signal via a waveguide network, to an output waveguide coupling the waveguide network to an output port. A portion of the +Z and -Z faces are coated at least partially with a conductive coating. A conductive path couples the +Z and -Z faces to prevent a charge differential from developing between the +Z and -Z faces due to a change in temperature of the optic chip and the pyroelectric effect.
