Abstract: ABSTRACT OF THE DISCLOSURE     The present invention provides an effective manner for combining a known vertical pump switch with a particular motor top plate.  Basically, the switch has a number of water entry points which must be sealed or controlled to such that the resulting combination satisfies the standards specified by the Canadian Standards Association.  The switch is of the type manufactured by Crouse-Hinds (trademark) under Catalogue 84594AM.  To adapt this switch for mounting thereof to a top mount motor plate, a gasket is provided having a deformable which cooperates with the switch and the motor top plate to provide a conduit such that water entering at the top of the switch is directed through the switch to the periphery of the motor plate. This gasket in some cases also seals water entry points.  The gasket is preferrably made of a neoprene material and may also carry an adhesive layer.

Abstract: ABSTRACT OF DISCLOSURE A hollow building wall including two wall components comprised of vertical arrays of stacked, integrally formed, hollow building blocks, which arrays are connected by vertically oriented, rigid separator splines that extend continuously from top to bottom of the wall at frequent horizontal intervals along the wall, to securely engage and support the two vertical arrays of building blocks.  Each edge of an individual spline is secured in one of a plurality of vertical grooves on the inner surfaces of each wall component.  Each building block is attached positively at each end to one or more horizontally adjacent building blocks.  The positive attachment  of horizon-tally adjacent building blocks and the separator splines forms in effect a structural "tube" that extends from top to bottom of the wall  and is connected positively with other similar "tubes" disposed along the length of the wall.  In its preferred form, the building wall has no mortar between vertically adjacent building blocks and no mortar between horizontally adjacent building blocks.

Abstract: METHOD AND APPARATUS FOR LOOPING AROUND A DIGITAL TRANSMISSION LINE AT A CHANNEL UNIT            Abstract Method and apparatus for looping around a digital transmission line (150) at a predetermined channel unit (172) to test the line from either end of the line.  Each channel unit in the line is responsive to a first and a second received control code to perform one of two operations.  When the first and second received control codes are both first predetermined control codes from one end of the line, the data channel assumes a state to pass the second received first control code and any subsequently received control codes to the next channel unit.  However, when the first and second received control codes are first and second predetermined control codes from the one end of the line, respectively, the data channel unit connects the transmit path from the one line end to the receive path back to the one line end, thus looping back the digital transmission line.  To loop around a line at a predetermined channel unit, a maintenance circuit (152) at one line end applies an individual first predetermined control code for the predetermined channel unit and each of the intermediate channel units followed by the application of a second predetermined control code for the predetermined channel unit.  The first channel unit from the end of the line passes the second received first control code and any subsequently received control codes to the next channel.  This continues for each unit until the predetermined channel unit receives only a first and a second predetermined control code.  The second received second control code causes the unit to loop around the transmission line.  A maintenance circuit at the other end of the line can likewise loop around the line at any channel unit.  A third predetermined control code causes each of the receiving channel units to return to their previous data transmission state.

Abstract: METHOD FOR ROUTING          Abstract of the Disclosure In a routing method for efficiently routing interconnections of a printed circuit board, an ordered list of interconnections to be made is first developed, each interconnection consisting of a source and a target.  The interconnection medium is notionally divided into cells and, in a flooding routine for deriving the route between a particular source and target, cells at a progressively increasing distance from the source are considered.  The progressive flooding is performed under a preset control by associating a respective cost with each of a number of possible flooding directions.  At any time, flooding occurs from that cell to which the accummulated cost of flooding from the source is a minimum.          Eventually a target cell is reached and by tracing backpointer directions associated with the intervening cells, the least cost route is derived as a series of contiguous line segments having position, length and orientation.  The same sequence is performed for all interconnections and the line segments are subsequently implemented as circuit board conductors and vias.
