Abstract: An integral structural element having improved sound and/or vibration dampening capacity and being composed of two support plates (1, 2) having therebetween spaced layers (3) of a viscoelastic material formed by a liquid synthetic elastomeric ma-terial having good adhesive properties and having a temperature resistance high enough to stand the temperature rise occuring due to the internal friction of the material while subjected to vibrations. The viscoelastic material between said two support plates (1, 2) is formed as strings of elastomeric material which are spaced from each other by a distance of 50-500 mm leaving an air space between the two support plates (1, 2) in the areas between adjacent strings of viscoelastic material (3). Each string (3) of dampening material has a material thickness of 1-5 mm, and a width of 10-50 mm. The structural element may, at the surface thereof to be mounted on a structural base, carry a mat of a natural or synthetic felt fibre material, having a product weight of 300-1200 g/m2 and having a thickness of 3-10 mm.

Patent CA-2141225-C (CA)
Inventor: BROWN CARL W JR
IPC: C23F13/12

Granted: 2007-03-20
Abstract: A metal coating of typically a valve metal, especially a titanium metal coating, is applied by thermal spraying to the surface of concrete, most particularly steel-reinforced concrete. The metal such as titanium may be sprayed by any one of several thermal spraying techniques including flame spray, electric-arc spray, plasma spray, high-velocity oxyfuel spray, or detonation gun spray. The metal coating should be tightly adhered to the concrete and desirably will have a porosity to facilitate extensive coating of the metal itself, as well as facilitate any activation that may be needed for the metal. Such activation can be in the form of an active material which allows the coating to function catalytically. One coating option is to apply a solution onto the spray-applied metal, then polarize the metal anodically to effect deposition of active material on the metal. Another option includes depositing active material directly onto the concrete, then applying an adherent, electrically conductive overlay such as a titanium metal coating to the treated concrete.

Granted: 2005-07-26
Abstract: Apparatuses and mobile stations are described which provide packet data services in TDMA (Time Division Multiple Access) cellular systems, based on providing shared packet data channels optimized for packet data. A first "integrated" embodiment utilizes the current cellular infrastructure to the extent possible consistent with functional and performance requirements.  Shared packet data channels (PDCHs) in base stations (BTS, BSC) may be provided dynamically determined by demand. A packet data (PD) controller in each Mobile services Switching Centre (MSC) controls access to the packet data services. A packet data router in each MSC routes packets to and from the MSC  service area. A backbone network interconnects packet data routers and Interworking Functions (IWF) providing internetworking with external network(s). A second "separated" embodiment, in order to minimize the impact on the current cellular system, primarily utilizes the base station portion of the cellular system, for the remaining network parts relying on a separate mobile packet data infrastructure.

Abstract: A tumbling bed of edible cores is formed which has a longitudinal axis extending from an entrance end to an exit end of the tumbling bed. Individual edible cores travel through the tumbling bed from the entrance end to the exit end by rotating in a generally helical path along the longitudinal axis of the bed. The edible cores are coated within the bed by repeatedly tumbling through both a wet zone(s) and a dry zone(s) formed within the bed. These wet and dry zones are formed, respectively, by spraying the surface of the tumbling bed with a hydrating liquid and by dusting the surface of the tumbling bed with a farinaceous powder. Both the wet and dry zones thus formed are generally rectangular, but not overlapping zones with the major dimensions  of these rectangular zones being substantially parallel to the longitudinal axis of the tumbling bed. Hydrating liquid and farinaceous powder are applied, respectively, to the wet and dry zones of the tumbling bed at rates which prevent aggregation of the edible cores and at rates which are suitable to form on the cores a dough-coating comprising flour, starch and sugar in a weight ratio of flour and starch to sugar of from about 05:1 to 30:1. The dough-coated edible cores are then cooked until crisp.

Granted: 2004-11-09
Abstract: A rolled paper towel dispenser having a spring (178) loaded cutting blade gearedto rotate in conjunction with a slotted drive drum (54). The blade is shielded by a fixed cowl (34). Guide rollers (68, 70) and the drive drum include threading clips. A brake mechanism ensures that the rolled towel cannot be free spooled. Supports (25, 26, 86) are provided for both a primary roll and a stub roll. Geared sensor arms sense the diameter of the stub roll and when the diameter decreases to a point near the end of the roll, the tail from the primary roll is automatically delivered to the surface of the drive drum and automatically threaded therethrough. To dispense a towel fromthe dispenser, the user grasps the tail of the towel extending from the dispenser and pulls downward. This drives the drive drum which in turn rotates the cutting blade into position severing the sheet at the proper location.

Abstract: The invention provides a circuit to protect an AC motor powered by a Variable Frequency Drive (VFD) from overvoltages caused by reflected waves. A full wave bridge rectifier circuit across the lines of the motor to be protected provides rectified voltage output to a capacitor, across which a low resistance discharge resistor in series with one or more zener diodes is attached. When an overvoltage above the clamping voltage of the zener diode(s) occurs across the protected lines, the zener diode(s) will conduct, causing the excess charge across the capacitor to discharge through the resistor until the voltage drops below the clamping voltage of the diode(s).
