Patent CA-2082983-A1 (CA)
Title: Packaging and dispensing system for fluid and semi-fluid cement admixtures
Inventor: DE MARS JOHN O
IPC: C04B24/00
Filed: 1992-11-16
Abstract: ABSTRACT      The present invention relates to a packaging and dispensing system especially suitable for semi-fluid or fluid cement admixtures.  The admixture is encapsulated in a material, such as gelatin or was, which ruptures, shatters, or disintegrates in the wet cementitious mixture during a period of mechanical mixing.  The present invention also contemplates a method of modifying the properties of cementitious mixtures by adding thereto an encapsulated admixture in a predetermined amount sufficient to provide a modified cementitious composition having the desired properties.

Title: Glycol-containing acid liquid composition and process for cleaning aluminum
Inventor: AOKI TOMOYUKI
IPC: C11D10/02
Filed: 1991-06-14
Abstract: The stability of an acidic liquid cleaner for aluminum comprising mineral acid, oxidant, polyvalent metal ions, and surfactant is substantially improved by the presence in the cleaner of from 0.05 to 5 g/l of a component selected from the group of glycols containing from 2 to 10 carbon atoms per molecule and mixtures of such glycols. The effectiveness of the cleaner for primary cleaning and desmutting of aluminum and its alloys is not impaired and may even be improved by the addition of the glycol component.

Inventor: WILSON ROBERT S
IPC: B32B7/08
Filed: 1991-06-26
Abstract: Apparatus for fastening together a plurality of horizontal layers of intermediate fabric material to form a stack (2) includes a first knife blade (4). The blade (4) has a forward cutting edge (6), and has a longitudinal slot (8) located therein. A second flat knife blade (10) is in sliding contact with the blade (4). The blade (10) is stationary, and its forward cutting edge (12) is located at a pre-selected distance above the upper surface (13) of the stack (2). The blade (4) is advanced to cut through the stack (2) until the slot (8) is clear of the lower face (16) of the stack. A pre-selected length of a tow (18) is threaded through the slot (8) to extend equal distances each side of the blade (4).  This blade (4) is then withdrawn until the cutting edge (12) of the blade (10) cuts the tow loop to form two independent tow pieces (20, 22). These pieces (20, 22) are each folded back onto the upper and lower faces (13, 16) of the stack (2) which is then cured.

Title: Arrangement for encasing a functional device, and a process for the production of same
Inventor: KVISTEROY TERJE
IPC: H01L/
Filed: 1992-05-05
Abstract: The invention relates to an arrangement for the encasing of a functional device, e.g., a semiconductor element, a semiconductor-based element, a sensor element, a microactuator, or an electronic circuit consisting of one or more integrated circuits and other electronic components, and a process for preparing an arrangement of this kind. Around the functional device (47) is arranged a casing (43, 45) which forms a closed cavity (51) which completely or partly surrounds the functional device (47). The casing is made of a plastic material or another polymer material. The casing consists of two or more joined components (43, 45). Metal parts which form wire bonds (46) with said functional device (47) in the casing pass through the walls of said casing. At least one of the casing pass through the walls of said casing. At least one of the casing components has filling holes or filling ducts (52, 53) for the introduction of liquid and/or gel material (56) into said cavity, and the filling holes or filling canals are sealed (54, 55) after the volume of the cavity has been filled with said liquid or gel.

Title: Out-of-pattern coating defect detection system
Inventor: FRAZEE RALPH E
IPC: G02B6/44
Filed: 1993-01-26
Abstract: Out-of-Pattern Coating Defect Detection System Abstract A defect detection system (10) of this invention applies one or more orthogonally-aligned light beams (22 and 24) to a coated fiber (32) such that the light passes through the entire width of both the fiber (32) and its applied coating (31). As the light passes through a fiber (32) and coating (31) of good quality, a particular pattern, with a predictable intensity level, is produced by the forward scattered portions of the light beams directed through the coated fiber (32).          In accordance with the present invention, the intensity of the forward scattered patterns is continuously monitored by a series of photodiodes (44, 45, 46 and 47) each located adjacent to the expected forward scatter pattern. Various defects in the coating cause the path of the light passing through the coated fiber (32) to be altered, thereby directing some of the forward scattered light outside of the normally expected pattern and into the detection area of the photodiodes (44, 45, 46 and 47). Such distortion to the forward scatter patterns causes the light intensity level measured at the photodiodes (44, 45, 46 and 47) to increase. Therefore, by continuously monitoring the light intensity level adjacent to the forward scatter patterns for an increase of light relative to the light intensity expected, the present invention provides reliable and accurate means for detecting, temporally short defects, such as air bubbles, which may be present within the coating (31) of a fiber (32).

Filed: 1993-10-04
Abstract: A local oscillator and its frequency switching method, in which  local signals with  less  spurious components can be obtained.   There are provided with frequency generators for generating signals with different frequencies and frequency dividers respectively connected to the generators. The dividers divide in frequency the signals to output them in an active mode, and output the signals without division in inactive mode.          The dividers are controlled so that one of the dividers is in the active mode and the rest is in inactive mode.  The output signals from the dividers are combined with each other to form a single output current and then is sent to a filter.   The filter selects a component with a desired local frequency from the single output signal. Spurious components due to unselected frequencies are removed by the filter since they are not divided.

Abstract: The  present  invention  describes  an  apparatus  for detecting  biological  activities  in  a  large  number  of  blood culture  vials.  The  vials  are  placed  in  discrete  disc-like segments comprising a drum and rotated about an axis.

Only a single detection station for each method is required for each segment and a plurality of stations may share common components, reducing cost while increasing accuracy.  The vials may be inserted into a segment using a quick disconnect method and a keying method is disclosed to guarantee the correct orientation of a vial once it is inserted.
