Patent CA-1060755-A (CA)
Inventor: CALLENBERG RUSSELL J
IPC: G05D16/06
Filed: 1976-11-05
Granted: 1979-08-21
Abstract: ABSTRACT OF THE DISCLOSURE           A pressure control valve wherein the monitored pressure acts against a diaphragm in opposition to a fixed biasing force which urges a poppet valve away from the seat.          A disc with a small orifice therein covers a sensing port whereby flow of the monitored pressure into and out of the diaphragm chamber is retarded to minimize chatter of the diaphragm.  A spring holding the orifice disc in place may be overcome by the monitored pressure to allow inward flow around the disc in the event that the orifice is occluded, whereby the valve will not enable undesirable pressure build up in the system in response to a false low pressure signal.

Abstract: ABSTRACT OF THE DISCLOSURE          Several embodiments of wall covering are provided all of which are directed to providing an insulated wall covering including panels commonly called "siding".  The wall covering is attached, by starting at the bottom of the wall and working upwards and is intended to provide a continuous insulating covering and to resist rattling and separation caused by building shrinkage.  A starter strip or board is provided at the bottom of the covering to permit some movement to relieve compressive forces in the siding caused by building shrinkage.          These forces are either transmitted directly from one piece of insulation to an adjacent piece of insulation, via structure forming part of associated siding panels, or by use of separate load transfer strips.

Abstract: ABSTRACT OF THE DISCLOSURE             To remove a solid tire from a wheel over which that tire has been pressed, a transverse groove is cut in the tread of the tire with a cutting apparatus so as to expose the underlying rim.  Then the exposed portion of the rim is cut with a flame that is passed through the groove.  Once the rim is severed, the tire is easily dis-lodged from the rim.  The cutting apparatus includes a base on which the wheel is positioned and slideways ex-tended away from the base generally parallel to the axis of rotation for the wheel on the base.  A slide is located along the slideways.  The slide carries a knife that is elongated in the direction of slide movement.  The knife has a free end provided with a point and cutting edges diverging from the point.  A threaded screw when turned down means the slide and the knife thereon, and the path of the knife is such that its point enters the tire at one side of its tread and after passing axially through the tread emerges from the other side.  In so doing, the knife cuts a segment in the tread.
