Patent CA-1128251-A (CA)

Abstract: IMPACT DEVICE              ABSTRACT OF THE DISCLOSURE An impact device, useful for driving nails, staples and other fastening elements.  The driving member is driven by frictional engagement with a rotating high speed flywheel.  The device has a safety provision whereby it cannot be actuated until the nose of the device is pressed against a work piece.  This action also produces a movement of a support means, such as a roller, towards the rotating flywheel.  It should be pointed out that the tool could be designed, in the alternative, with a fixed support means and movable flywheel.  Actuation of the trigger moves the driving member into engagement between the support and the rotating flywheel, and the flywheel propels the driving element in a fastener driving direction.  The support means is provided with a leaf spring permitting it to yield so that the driving member can pass between the flywheel and the support means while maintaining frictional engagement between the flywheel and the driving member.  Inertia  of the support means aids in efficient engagement of the fly-wheel with the driving member.  The driver is connected to an elastic member, so that when the tool is lifted from the work, the movable support means is moved away from the fixed flywheel, and the elastic member then retracts the driving member between the flywheel and the support means to a position out of contact therewith.  The flywheel can be driven by any of several drive means including compressed air, internal combustion and electric drive means.  The preferred embodiment is powered by a single electric motor.

Abstract: AUTOMATIC SAWMILL METHOD AND APPARATUS                   Abstract A cant or plank is moved forwardly on a conveyor system, where its irregular leading lateral edge is measured by a plurality of fixed scanners.    In response to measurement of the cant, conveyor move-ment is altered for orienting the cant relative to a predetermined saw line to be executed by a movable saw whereby the wane will be removed tangentially thereof.          The cant is held or clamped in stationary position while the saw is moved on a carriage relative thereto, re-sulting in severing of the undesired irregular forward edge.  The sawn edge is employed as a reference as the cant is then moved forwardly on a conveyor system, where the measurements obtained from the scanners may be further utilized in cutting the cant into desired widths.

Abstract: ABSTRACT     A magnesia partially stabilised zirconia ceramic material possessing from about 2.8 to about 4.0 wt per cent magnesia, and made from a zirconia powder containing no more than about 0.03 per cent silica is described.  The ceramic material has a microstructure, produced as a consequence of the method by which the material is made, which provides both high strength and good thermal shock resistance properties.  This micro-structure comprises grains of cubic stabilised zirconia within which are formed, during cooling from the firing temperature, precipitates of tetragonal zirconia.  These precipitates are elliptical in shape, with a long axis of about 1500 Angstrom units.   Additionally, some of the tetragonal zirconia precipitates are made to transform into a non-twinned microcrystalline monoclinic form of zirconia by reducing the temperature of the material to below 800°C, then subsequently holding the material at a temperature in the range from l000°C to about 1400°C.  The ceramic material may also contain up to 36 wt per cent of hafnia.       Such materials can be used for, inter alia, moulds, dies, tappet facings and cutting tools.

Abstract: Abstract A flow line bundle assembly includes a plurality of con-duits disposed within a tubular covering member.  The tubular covering member is sealed at its ends before being placed in a body of water, so that the flow line bundle has a slight positive buoyancy when submerged in the body of water.  Weights are then added to the flow line bundle to cause it to have a neutral buoyancy at a position slightly above a floor of the body of water.  The flow line bundle is then towed from its point of construction, through the body of water, to the loca-tion where it is to be installed.  During a first method of towing, if an obstacle located above the ocean floor is approached, a trailing tug increases a restraining force applied to the flow line bundle so as to lift it above the obstacle as the flow line bundle  passes over the obstacle.  A second method of towing maintains the flow line bundle at a constant depth below a surface of the body of water so that the bundle will clear any obstacles on the floor of the body of water.  After the flow line bundle is connected between a subsea wellhead and a producing platform located within the body of water, the space between the conduits and the tubular covering member is flooded to sink the flow line bundle to the ocean floor and to provide heat transfer between the conduits and the tubular covering member.
