Title: Floating heating modules for driveway snow melting
Inventor: DAHAN GEORGE S
IPC: H05B3/26
Filed: 1990-03-15
Abstract: ABSTRACT   In the present method for snow melting on driveways using heating cables, the heating cables are normally buried inside concrete slabs. However this method inherently confines itself to concrete slab pavements Therefore development workhas been deemed necessary to render the heating system: Adaptable to different kinds of surface pavements especially the popular stone pavement whose floating character and its higher resistance to the heat flow (the heat has to travel through 4" of sand and concrete) renders its heating by existing methods difficult. Efficient as far as heating is concerned by creating a heat sink made of a double steel wire mesh around which the heating cable is wound. The wire mesh, due to its relative high conductivity, absorbs the heat quickly from the heating cable, prevents the cable from overheating, and diffuses the heat upwards where it is required The imbedded styrofoam sheet prevents the heat from being lost downwards. Floating i.e. the modules should be free to follow the earth settlement if it occurs without straining the electrical connections. Modular i.e. composed of adjascent heating modules easily manufactured and readily expandable

Patent CA-2036673-A1 (CA)
Inventor: BENNEYWORTH DOUGLAS F
IPC: E01D19/06
Filed: 1991-02-19
Abstract: ABSTRACT            A method for constructing a bridge joint in a channel (13) overlying an expansion joint (5) involves lining the channel with a thermoplastic asphaltic elastomeric binder (26) followed by successive applications of layers (28, 30) of aggregate and binder mixture wherein the thickness of each layer is restricted to about the maximum dimen-sion of the aggregate in the layer.  Care is taken to insure that both the binder and the aggregate are hot when the layered joint is formed to insure good bonding between layers and with the roadway material.  The aggre-gate of each layer (28, 30) is raked to project upwardly from the mass of the layer before a subsequent layer is applied to enhance the interlock between layers.  A final layer (32) containing smaller aggregate is applied at the joint top and the joint is then sealed and rolled to form an integrated, resilient load bearing structure.

Title: Programmable signal filters
Inventor: HARRIS TIMOTHY A
IPC: F16C32/04
Filed: 1992-04-03
Abstract: Programmable Signal Filters ABSTRACT OF THE INVENTION     Magnetic bearing systems are commonly employed in rotary machinery to support the shaft within the housing of the machine. Magnetic bearing systems typically have electronic signal processing circuits which are supplied with an electrical signal indicative of shaft movement. These circuits process the electrical signal and provide a suitable response signal which is used to reposition the shaft within the magnetic bearing. Within the signal processing circuits, it is common to employ electrical signal filters which serve to prevent the output of response signals at specified requencies. To prevent the output of the response signals at specified frequencies, the electrical signals filters must be suitably configured.  This invention provides an electrical signal filter which may be configured by a programming means without the need for exchanging electrical components.
