Title: Method of forming seamed metal tube
Inventor: KRENGEL THEODORE H
IPC: B05C9/10
Filed: 1994-06-15
Abstract: The method of forming a seamed metal tube (20c) having a metal coating (56) of this invention includes galvanizing the strip (20) prior to welding. The strip (20) is then formed into an open seam tube (20b) and welded in an inert atmosphere with the seam (71) located in the lower portion of the tube. Finally, the metal coating (56) is caused to flow downwardly over the seam (71), coating the seam (71) by several means. In one embodiment, the strip (20) is preformed into an arcuate shape (20a) and galvanized, wherein the zinc coating (56) increases in thickness toward the lateral strip edges (48), such that the coating (56) will flow over the seam (71) following welding. The tube (20c) may also be reheated following welding, preferably in an enclosure (78) containing an inert atmosphere which includes the weld apparatus (62). In another embodiment, an inert gas is directed over the inner and outer surfaces of the tube (20c), adjacent the seam (71), driving the molten metal downwardly over the seam (71) to coat the seam (71). In another embodiment, the lateral edges (48) of the strip (20) are formed with indentions or grooves (188) directed toward the lateral edges (48) which direct the molten metal downwardly over the seam (71).

Title: Resettable internal actuating mechanism for use with an electronic sectionalizer
Inventor: TWENTER BYRON T
IPC: H01H31/28
Filed: 1996-05-07
Abstract: A resettable internal actuating mechanism, used in an electronic sectionalizer having a tube assembly movable between a closed position and an open position, includes a latching element of an electro-mechanical component mounted in the tube assembly and biased to move to an extended position and movable to a retracted position in response to receipt of an electrical signal, an actuating member spaced from the latching element and mounted in the tube assembly and being biased to move from a non-actuated position to an actuated position, and a linking lever mounted in the tube assembly between the latching element and the actuating member and biased to pivotably move from a latched position to an unlatched position.      The linking lever has opposite ends latched respectively to the latching element and actuating member when the linking lever is at the latched position and the latching element is at the extended position to thereby hold the actuating member at the non-actuated position. The opposite ends of the linking lever unlatches respectively from the latching element and from the actuating member in response to the latching element being moved to the retracted position to thereby release the linking lever to move to the unlatched position and the actuating member to move to the actuated position. By moving from the non-actuated to the actuated position, the actuating member extends outwardly from the bottom end of the tube assembly and moves an external latching mechanism of the electronic sectionalizer from a locking position to a releasing position to cause movement of the tube assembly from the closed to the open position.

Title: Method for producing decorated glass panels
Inventor: EASTON LESLIE RALPH
IPC: B44F1/06
Filed: 1994-11-30
Abstract: A method of making decorated glass panels, particularly glass panels decorated with designs to simulate stone such as marble, is described. Water-slide transfers (10) are formed by printing designs simulating marble on a backing of gummed paper with an ink of glass frit and coloured metal oxides in a printing medium. Several transfers (10) are soaked in water and then removed from their backing and placed in overlapping relationship on a panel of glass (15). The transfers are cut through in the region of their overlap (16) and the surplus material removed. After drying the panel is passed through a furnace to burn off the printing medium. A coating of ceramic or vitreous enamel material (25) is applied over the design and the panel is then subjected to a second heat treatment cycle in which the glass frits and metal oxide fuse to the glass panel, the coating is baked on to the panel and the glass is toughened by rapidly heating in a furnace and then cooling.

The second output IDT can comprise a coded IDT, or a delay tap responsive to the surface wave propagated via the first coded output IDT.
Patent CA-2201834-A1 (CA)
Inventor: WEBSTER STEPHEN PAUL
IPC: H04B3/04
Filed: 1997-04-04
Abstract: A serial digital data communications receiver with an improved automatic cable equalizer that is less susceptible to jitter and has greater multi-standards capability, and an improved automatic gain control system with a DC restorer that provides optimal edge jitter performance while avoiding the possibility of a latch-up condition at the start of data transmission. The automatic cable equalizer for equalizing signals received over cables of different lengths has multiple stages each having a transfer function of 1 + Ki[fi(j~)] wherein each of the Ki vary in accordance with a sequential gain control methodology. The AGC system uses the difference between pass band filtered versions of the amplitudes of the input and output of a DC restorer based on quantized feedback, to regulate the AGC circuit. The DC restorer comprises a comparator for generating a quantized output and further clamps the input with a clamping circuit so that a version of the quantized output is fed back to the input while avoiding the possibility of operational failure of the comparator at the onset of data transmission.
