Patent CA-2127073-A1 (CA)
Inventor: NATTEL WILLIAM
IPC: H02G3/12
Filed: 1994-06-29
Abstract: An electrical outlet box is formed from side plates and a U-shaped plate forming top, bottom and rear walls. The side plate has bosses, projecting outwardly from the box to ensure that the box is uniformly spaced from a vertical surface, for example the side of a stud. To facilitate mounting of the box to a stud, at least one boss has an aperture therein for receiving a screw or other fastener. Preferably, this aperture has an axis angled so that the axis passes through the front opening of a box. The bosses with apertures can include planar central portions for receiving a screw head and further can have an outer portion to the aperture for receiving part of a screw head to minimize protrusion of the screw head into the box. The screw head is then recessed away from the interior of the box to prevent shorting of electrical context, and as it is located in a boss contacting the stud or other surface, unwanted distortion of the side plate is avoided.

Title: Roofing laminate
Inventor: URBANEK THOMAS W
IPC: B32B11/02
Filed: 1995-02-17
Abstract: A new roofing laminate provides for the application of mixture of hard and soft acrylic polymers to a hot or cold applied asphaltic layer.

Title: Individually wrapped disposable absorbent article which becomes elasticized when unwrapped
Inventor: MUCKENFUHS DELMAR RAY
IPC: A61F13/15
Filed: 1993-08-25
Abstract: An article of manufacture is disclosed for absorbing liquids, particularly body fluids such as menses. The disclosed article is disposable and has a wrapper associated therewith. An elastic material is secured to the backsheet and is maintained in a substantially tensioned state until separation of the wrapper from the backsheet. Upon separation of the wrapper from the backsheet the tension in the elastic member is released causing the disposable absorbent article to form an upwardly cupped configuration to conform more closely to the wearer's body.
Patent CA-2143795-A1 (CA)
Title: Method for blow molding hollow articles and device for the same
Inventor: MATSUHASHI SETSU
IPC: B29C49/60
Filed: 1995-03-02
Abstract: In a blow molding process, a fused thermoplastic polymer parison is interposed between a pair of split molds. The split molds are closed around the parison to seal the ends. A small diameter hollow needle is inserted through one of the split molds and fluid is blown into the parison forming a balloon. After the balloon begins to form, a large diameter hollow needle is inserted while internal pressure is applied to the parison via the small diameter hollow needle, and a large amount of fluid is blown in. If the balloon contacts the sides of the molds before fluid is blown through the large diameter hollow needle, a glossy bottle is formed. This process is highly productive and reduces the conventional blow molding cycle by 60 percent due to the rapid cooling of the hollow article.
Patent CA-2146754-A1 (CA)
Title: Treatment of tumors by selective protein depletion
Inventor: TEPIC SLOBODAN
IPC: A61K35/14
Filed: 1994-08-09
Abstract: The invention describes a method of treatment of tumors based on a fundamental dynamic difference between the normal and tumor cells, which underscores the very danger of tumors - their propensity to grow and proliferate under conditions where normal cells would not do so. The preferred mode of treatment is by extracorporeal blood conditioning, whereby the concentration of one of the (essential) amino acids is the control parameter. The blood is passed through a filter where the blood cells and the high molecular weight constituents are separated from a plasma fraction containing low molecular weight substances, including amino acids. The fraction with low molecular weight substances is reacted against either adsorption or decomposing agents and returned to the blood. The filtration is done to decrease the concentration - increase is controlled by simply injecting the amino acid. A single treatment session includes at least four phases whereby the concentration is first decreased (collecting all cells in the G0 phase); then increased (pushing the tumor cells over restriction point); then decreased to minimnm level possible (killing the tumor cells); and finally normalized.

Patent CA-2164891-A1 (CA)
Title: Optimizing Printing Speed and Managing Printed Sheet Ejection Based on Image Density and Method of Determining Density
Inventor: COURTNEY THOMAS P
IPC: G06K15/10
Filed: 1995-12-11
Abstract: The printing operation of an ink jet printer is controlled based on the density of the image to be printed. Using the density, a required drying time for each swath of printed matter is determined based on the image density. Also using the density, a maximum print frequency of firing the ink jets is determined. The density is determined by filtering stored print data by dividing the print data into blocks and determining a maximum number of ON pixels in a block. Such filtering enables clusters of ON pixels to be detected thus providing a more accurate determination of the density.
Patent CA-2174308-A1 (CA)
Inventor: STOECKER JUERGEN
IPC: F16B21/02
Filed: 1996-04-16
Abstract: The present invention relates to a self-adjusting stopper for dampening movable parts, in particular for lids, hoods or the like in automotive vehicles, comprises a stop ele-ment, a casing, a clamping element and a coupling element in cooperative relationship. Initially the damping element pro-jects a maximum distance out of the casing. By closing the part which has to be dampened, for example the hood of an automotive vehicle, the damping element becomes displaced into the casing. After opening the lid the clamping element is locked to the damping element by rotating the coupling element to axially adjust the damping element within the casing. A further adjustment is not required. According to the invention, the damping element will be automatically adjusted in a proper axial position by just closing and opening the lid.
