Patent CA-2188932-A1 (CA)
Title: Process for evaluating fertility of spermatozoa samples
Inventor: HAMMERSTEDT ROY H
IPC: C12M3/04
Filed: 1995-04-26
Abstract: A method for testing the potential fertility of spermatozoa in a sample by contacting an aliquot of the sperm sample onto a protein extracted from native vitelline membranes removed from chicken  or turkey eggs to enable quantification of the number of sperm which bind to the protein. Typically, the vitelline membrane protein is coated onto a solid substrate and the protein extract is first prepared by dissecting vitelline membranes (lamina perivitellina plus lamina extravitellina) from either a group of chicken eggs or a group of turkey eggs, rinsing the membranes free of albumin and yolk and subdividing the membranes into small particles. The resulting protein is heat solubilized, purified with centrifugation and concentrated to yield the protein extract in solution. The extracted protein then is used as a protein substrate for spermatozoa binding, with sequential contacting of the protein extract with the spermatozoa and measuring the amount of sperm-egg binding that takes place. Intact egg membranes may alternatively be used to bind sperm. Correlation between sperm-egg binding and fertility of the spermatozoa in the sample is direct and linear.

Patent CA-2197541-A1 (CA)
Inventor: LEHMANN WALTER E
IPC: F25B29/00
Filed: 1997-02-13
Abstract: A refrigeration/heat pump system comprises a compressor, condenser, evaporator and expansion valve all of which are mounted within a rectangular housing for convenient layout and accessibility. The condenser, evaporator and expansion valve are all oversized relative to the compressor so as to obtain modifications in the operating parameters and particularly a compression ratio of the compressor which is less than 4.5:1. This mismatch of the components surprisingly provides an enhanced efficiency of operations in tons/hp. The components are arranged in the housing with the compressor centrally of the housing, the evaporator along one side, the condenser along the opposed side and with the system connections in the rear wall. The electrical components are provided in a vertical compartment on one side of the front wall which can be accessed by an opening door. A removable panel in the front wall and in the rear wall allows access to the components.

Filed: 1996-10-09
Abstract: Diamondlike carbon is deposited on a deposition substrate (46) in a deposition apparatus (40) that can be evacuated and backfilled with a carbonaceous gas. A plasma (68) is generated in the gas by heating a filament (62) within the chamber (42) to produce electrons, and positively biasing the filament (62) with respect to the deposition chamber wall (44) to accelerate the electrons into the carbonaceous gas. The carbonaceous gas dissociates and ionizes in the resulting plasma (68) to produce positively charged carbon ions. The deposition substrate (46) within the chamber (42) is negatively biased with respect to the deposition chamber wall (44), accelerating the carbon ions so that they are deposited onto the surface of the substrate (46).

Title: Three dimensional packaging configuration for multi-chip module assembly
Inventor: HAWKE ROBERT E
IPC: H01L25/065
Filed: 1997-10-10
Abstract: A multi-chip module (MCM) assembly has three stacked integrated circuit (IC) layers. The first IC layer is electrically flip-chip connected to a substrate. The back of the second IC layer may be glued to the back of the first IC layer, and the second and third IC layers are electrically flip-chip connected to each other. In one embodiment, the third IC layer is electrically connected to the substrate through a vertical interconnect element for high circuit density. In another, the second IC layer is electrically connected to the substrate using wire bonding for greater post-fabrication customization flexibility. In still another embodiment, the MCM assembly comprises two stacked IC layers where the second IC layer is electrically flip-chip connected to the first IC layer and the second layer is electrically connected to the substrate through a vertical interconnect element. By directly connecting IC layers, higher circuit density, lower trace impedance, and lower cross-talk or electrical noise susceptibility is achieved over that presently offered by most current MCM assemblies. The assembly accommodates different sized IC layers, multiple ICs on each layer, and different technology-based IC layers and ICs within each layer, providing the user with high design flexibility within a single multi-chip assembly.
