Patent CA-2225262-C (CA)
Inventor: MARTINEAU JULIEN
IPC: E04G17/06
Filed: 1997-12-19
Granted: 2006-04-25
Abstract: A retainer is disclosed to act as a substrate for nailing or screwing to with insulating foam board and concrete, particularly to insulating foam board used as a foam for pouring concrete. The retainer has a head with a face adapted to receive and anchor fasteners such as nails or screws, an elongated arm extending substantially perpendicularly from said head on the side remote from such face. The arm has means to embed the arm in concrete during pouring such that the arm will not retract from the concrete after the concrete has hardened. Optionally, the retainer has a clip to attach to a tie rod extending between concrete forms, to position the tie rod with respect to the forms. The retainer is put in place before the concrete is poured. After the concrete hardens, wall surface materials and the like can be screwed or nailed to the face.

Abstract: A catalytic process and apparatus therefor for the manufacture of hydrogen cyanide. In the process an oxygen rich oxidant stream and at least one oxidant-free feed stream containing methane and ammonia are separately preheated and rapidly mixed to form a detonable mixed stream at a temperature which is at least 50 °C below the autoignition temperature of the mixed stream. The mixed stream is then conveyed to a catalyst capable of catalysing the formation of hydrogen cyanide at such a velocity that detonation is avoided. The process is more energy efficient and gives rise to an effluent stream containing more hydrogen than the conventional Andrussow process.

Abstract: A splitter separates telephony traffic (POTS) from digital subscriber line (ADSL) traffic occupying a higher frequency band. The splitter comprises a low-pass filter for passing the telephony traffic, the low-pass filter being operable to vary its filtering response between a first low-pass response for use during telephony speech traffic, and a second, more restrictive, low-pass response for use during at least part of the time that telephony signalling traffic is present. During speech traffic a filter is used which provides a good impedance match with a telephony terminal or linecard so as to minimise detrimental effects on sidetone and echo performance which may impair a user's speech quality. The filter response can be varied according to a detected property of the telephony traffic, such as amplitude or rate of change of amplitude of the traffic.

Title: Automatic washing machine incorporating a suds detection and control system
Inventor: ERICKSON DONALD E
IPC: D06F39/06
Filed: 1998-10-30
Granted: 2004-09-21
Abstract: A washing machine for automatically laundering articles of clothing by imparting mechanical actions upon the articles of clothing within a basket of the machine during a washing operation that includes a wash cycle and a preset number of rinse cycles incorporates a control system that functions to alter the mechanical actions imparted upon the articles of clothing during at least the wash cycle, and preferably both the wash cycle and at least one of the rinse cycles, and/or adds a supplemental rinse cycle to the overall washing operation in response to an indication of a high suds level condition in the machine. The control system receives signals indicative of an operating parameter of the washing machine, such as the input torque or operating speed of a motor of the machine, from a detection unit and utilizes these signals to determine the presence of high levels of suds and the need to transfer to a suds reduction mode of operation. In at least a preferred embodiment of the invention, provisions are made to recover from the suds reduction mode by returning to the normal washing operation and/or simply cancel the supplemental rinse cycle.

Abstract: An on-machine-seamable multi-axial press fabric for the press section of a paper machine is made from a base fabric layer assembled by spirally winding a fabric strip in a plurality of contiguous turns, each of which abuts against and is attached to those adjacent thereto. The resulting endless base fabric layer is flattened to produce first and second fabric plies joined to one another at folds at their widthwise edges. Crosswise yarns are removed from each turn of the fabric strip at the folds at the widthwise edges to produce seaming loops. The first and second fabric plies are laminated to one another by needling staple fiber batt material therethrough.      The press fabric is joined into endless form during installation on a paper machine by directing a pintle through the passage formed by the interdigitation of the seaming loops at the two widthwise edges.

Title: Anti-viral, anhydrous, and mild skin lotions for application to tissue paper products
Inventor: KLOFTA THOMAS JAMES
IPC: A61K8/97
Filed: 1997-05-30
Granted: 2008-02-12
Abstract: A lotion composition for killing such viruses as rhinovirus and influenza in addition to imparting a soft, lubricious, lotion-like feel when applied to tissue paper in amounts as low as from about 2 to about 20 %  by weight, and tissue paper treated with such lotion compositions are disclosed. The anti-viral action of the lotion is due to the addition of an organic acid such as citric acid or a mixture of adipic acid, glutaric acid, and succinic acids. The solubilization of the organic acids within the lotion matrix and with the infected mucus is aided by the addition of such hydrophilic solvents as propylene glycol and polyethylene glycols. The lubricious lotions also contain a plastic or fluid emollient such as petrolatum, an immobilizing agent such as a fatty alcohol or fatty acid to immobilize the emollient on the surface of the tissue paper web and optionally a non-ionic surfactant to improve wettability when applied to toilet tissue. Because less lotion is required to impart the desired soft, lotion-like feel benefits, detrimental effects on the tensile strength and caliper of the lotioned paper are minimized or avoided. The anhydrous nature of the lotions also aids in the maintenance of such physical properties as tensile and caliper.

Abstract: The invention concerns a method for making identity cores for ultrasound seals. Each core comprises a chip consisting of a brazed stack of metal disks 1 bearing at least one notch 3, the resulting identity being defined by the number, the size and the random angular position of the various notches in the stack and by the unpredictability of the brazing. The invention is characterized in that the notched disks 1 provided with a central hole 2 are first stacked in large numbers in a tubular metal sheath 4 with a circular cross-section corresponding to said disks 1. The stack is then axially compressed in the sheath 4 and a brazing bead 7 is inserted in the channel constituted by the assembly of aligned central holes 2. After brazing in a vacuum oven, the two ends of the sheath are eliminated and the resulting column is segmented perpendicularly to its axis into a series of individual identity chips 8 of predetermined thickness. Such a chip is finally associated by brazing with a metal block 13 used as delay line to constitute the core. Identity control can be combined with integrity control by associating an integrity rod 10 to 12 with said block 13, whereby with one reading both identity and integrity can be ascertained.
