Abstract: ABSTRACT OF DISCLOSURE:      A venting device providing an air vent passage between the soffit space and attic space of a structure and a baffle for retaining insulation material in the attic.  The venting device has a generally V-shaped body forming with the roof an air vent passage leading from the soffit space to the attic space.  The V-shaped body is located between adjacent roof rafters with an air vent passage leading from the soffit space to the attic space.  The V-shaped body is located between adjacent roof rafters with flanges on opposite sides of the body that engage the roof boards and the adjacent roof rafters. The forward end of the body has foldable baffles that close the space between the sill plate and the roof boards leaving the passage formed by the V-shaped body open so that the insulation material in the attic does not block the soffit and passage between soffit space and attic space.

Abstract: ABSTRACT OF THE DISCLOSURE           An electronic telephone switching system is described having peripheral units including a plurality of subscriber and line circuits, a plurality of trunk and tie line circuits, at least one attendant line circuit, a plurality of signaling tone receivers, and a plurality of link control circuits.          Switching is carried out by a one wire speech path switching matrix and a one wire tone switching matrix.  The system is centrally controlled and includes a central processing unit, a program memory, a scratch pad memory and a customer memory.          Information, commands and addresses are communicated between the peripheral units and the central control and within the central control via bus lines.  The bus lines between the peripheral units and the central control transmit data with lower rise time pulses than the bus lines interconnecting the components of the central control.  Each electronic crosspoint switch has a two terminal conducting path and a control terminal for controlling the state of conduction of the conducting path.  Different conducting path terminals of the speech path matrix and tone path matrix crosspoint switches are operated by the same peripheral link unit.  The matrix coordinates to be operated are defined by polling the different periphal units connected to the coordinates in question.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to electrical connectors of the insulation-opening type and, more particularly, to electrical connec-tors having contacts with flexible sidewalls which hold the contacts in the cavities of the connectors.  The contacts generally include terminal elements which sever the insulation and establish an elec-trical connection with the conductor without the need for any stripping or soldering operation.  Since the insulation-piercing contacts may be most economically manufactured by stamping operations,  It is necessary to use sheet metal stock which is easily formable.  Accordingly, the insulation-piercing terminal elements of prior art contacts may be deformed in the connecting operation to the point where proper elec-trical connection is adversely affected.  Additionally,  prior art insul-ation-piercing connectors are not well suited to stranded core conduc-tors.  According to the present invention,  at least one of the side-walls includes a portion which Is displaceable from an initial,  pre-assembly position wherein the transverse dimension of the contact Is greater than the transverse dimension of the cavity, to a final, assembled position wherein the sidewalls are located within and en-gage the lateral surfaces of the cavity.  In addition, the contact includes at least one pair of protuberances which form a conductor-receiving notch adapted to open or displace the insulation and make electrical connection with the conductor.  The various structural components of the contact are dimensioned relative to each other and the conductor being terminated to minimize the changes in termination resistance which typically occur when stranded core conductors are terminated with conventional contacts.
