Patent CA-2057885-A1 (CA)
Title: Mail bags
Inventor: LINNELL MICHAEL CHARLES
IPC: B65D33/00
Filed: 1990-05-16
Abstract: A mail bag has supports (10) adjacent its mouth, each comprising a generally flat elongate (12) part fixed to the bag fabric with its longitudinal axis generally parallel to the edge of the bag mouth and having attachment means by means of which in use the bag is supported. The attachment means may comprise apertured attachment members (14) formed integrally at one or more locations along the length of the elongate parts on edges thereof to extend generally normally away therefrom. In one arrangement (Fig. 2) the bag has four supports, each elongate part being in length substantially a quarter the length of the edge of the bag mouth and the attachment members being formed substantially at the midpoints thereof. In another arrangement the bag may have two supports each elongate part being in length substantially a half the length of the edge of the bag mouth and foldable at its midpoint and the attachment members being formed at respective locations substantially midway between the ends and midpoint of the elongate part. The elongate parts may be located in a hem at the bag mouth with the attachment member passing through an aperture in the hem.  Alternatively the elongate part are directly fixed - sewn - onto the bag fabric as the bag is made. The supports may be of moulded plastics material - advantageously of the same material (polypropylene) from which the bag fabric is woven. A support for use in making a mail bag is claimed as is a method of making a bag - which method may include the use of bag fabric with woven differently coloured stripes (22) spaced to enable the ready correct positioning of the elongate parts on the bag fabric.

Title: Ice fishing device
Inventor: ROSZKO GEORGE
IPC: A01K97/01
Filed: 1992-03-10
Abstract: ABSTRACT OF THE DISCLOSURE          An ice fishing device for trapping a fish in a hole in the ice includes a pair of coaxial, hollow cylinders, one of which is slidably mounted in the other.  Flexible fingers extend inwardly from the outer cylinder through slots in the bottom end of the inner cylinder.  The fingers have inwardly curving upper ends, so that downward movement of the inner cylinder into the outer cylinder causes the fingers to move inwardly to define a partial wall or gate, which prevents the escape of a fish from within the inner cylinder.
Patent CA-2062754-A1 (CA)
Inventor: UEKI AKIO
IPC: A61F7/08
Filed: 1991-02-25
Abstract: A disposable body warmer in which a heat-generating agent which oxidizes and generates heat by the presence of air is contained in a flat bag. At least one surface of the flat bag is made air permeable so that pressure in the flat bag is reduced by exothermic reaction of the heat generating agent, and a self-adhesive layer is provided on either surface of the flat bag.      Since the heat-generating agent contains high performance activated carbon having an iodine adsorption of 800 to 100 mg/g and a methylene blue decoloring power of 100 to 300 mg/g, the rising in temperature is fast and duration is long in comparison with conventional body warmers.

Title: Projective training system for neural networks
Inventor: DENKER JOHN S
IPC: G06T7/00
Filed: 1992-05-28
Abstract: In order for neural network technology to make useful determinations of the identity of letters and numbers that are processed in real time at a postal service sorting center, it is necessary for the neural network to "learn" to recognize accurately the many shapes and sizes in which each letter or number are formed on the address surface of the envelope by postal service users. It has been realized that accuracy in the recognition of many letters and numbers is not appreciably sacrificed if the neural network is instructed to identify those characteristics of each letter or number which are in the category "invariant." Then, rather than requiring the neural network to recognize all gradations of shape, location, size, etc. of the identified invariant characteristic, a generalized and bounded description of the invariantsegments is used which requires far less inputting of sample data and less processing of information relating to an unknown letter or number.
Patent CA-2070107-A1 (CA)
Inventor: HAYNES JOHN L
IPC: G01N1/12
Filed: 1992-06-01
Abstract: A vented cap and capillary tube assembly is disclosed together with a method of use of such assembly. The assembly includes a capillary tube having a bore extending therethrough and a cap slidably mounted to one end of the tube.  The cap includes one or more vent grooves therein which allow air to escape therethrough when the cap is in a first slidable position.  The walls of the capillary tube prevent air from escaping through the vent when the cap is more fully inserted within the tube.  The method provided herein includes the steps of providing such a pre-assembled capillary tube and vented cap assembly, maintaining the cap in the first position while the opposite end of the capillary tube is inserted within a liquid sample, allowing the liquid to enter the tube through capillary action, thereby displacing air within the tube through the vent, and sliding the cap to the fully inserted position, thereby sealing the vent. The cap used in conjunction with the capillary tube is made of an elastomeric material, and has a slippery surface.  It includes an enlarged head having a cylindrical plug extending therefrom.  The plug includes a sealing ring for engaging the inner wall of the capillary tube.  It also includes an annular groove adjacent the enlarged head which facilitates the seating of the head on the end of the capillary tube.

Patent CA-2082424-A1 (CA)
Inventor: CAMPBELL ROBERT K
IPC: C07K19/00
Filed: 1991-05-07
Abstract: The invention relates to modified chorionic gonadotropin (CG) alpha, beta-heterodimeric polypeptides comprising a gly-coprotein hormone alpha-subunit polypeptide and a non-naturally occurring beta-subunit polypeptide. The modifications in the beta-subunit polypeptide involve tho deletion, addition, or substitution of one or more amino acid residues. The modified heter-odimeric polypeptides of the invention have different properties compared to native hCG. Certain alpha, beta-heterodimeric pol-ypeptides bind to LH and FSH receptors and stimulate steroidogenesis in testicular and ovarian cells. Other alpha, beta-heterodi-meric polypeptides bind to LH receptors but have lower efficacy than hCG to stimulate steroidogenesis in testicular and ovarian cells.

Abstract: ABSTRACT OF THE DISCLOSURE A sequentially timed parallel light sensitive control system for swimming pool circulation pumps and hydrocarbon pool heaters.  The system comprises a photoelectric switch that is connected in series to a pilot rated relay with an electrically isolated contact that, at sundown, interrupts the millivolt circuit control of a swimming pool heater at a predetermined period of time prior to a second photoelectric switch which is connected in parallel to the first photoelectric switch and which thereafter disables a horsepower rated relay for shutting off the pool circulation pump.  At sunrise, this cycle is reversed, with the circulation pump starting at a predetermined period of time before the swimming pool heater.
