Patent CA-2035053-C (CA)
Inventor: MCASKILL JOHN P
IPC: F16H3/093
Filed: 1991-01-28
Granted: 1994-11-01
Abstract: SIXTEEN SPEED POWERSHIFT TRANSMISSION      ABSTRACT OF THE DISCLOSURE    A 16-speed drop box transmission is provided in a particularly compact double-diamond arrangement.  Most of the shafts in the transmission, as well as many of the gears and clutches, are identical and interchangeable.  This significantly reduces the number of different parts needed to make the transmission.  Most of the gears which do the actual power modification to produce the various gear ratios are rotatably mounted about these interchangeable shafts.  The basic design is highly flexible, since different gears may easily be substituted for one or more of these rotatably mounted gears to produce a transmission with different gear ratios.
Patent CA-2038750-C (CA)
Title: Process and apparatus suitable for effecting steel band guidance
Inventor: BIELFELDT FRIEDRICH BERND
IPC: B27N3/24
Filed: 1991-03-21
Granted: 1999-01-19
Abstract: The present invention relates to a process for correcting misalignment of steel bands circulating about a continuously operating press and to a press adapted for such correction of misalignment.  The press has a fixed press bed and a movable press top and a pair of endless flexible steel bands circulating around the press bed and the press top and defining a press gap between them having a high pressure zone, a medium pressure zone and a low pressure zone.  The press top is flexible, at least in the high pressure zone, the flexing being controlled by piston and cylinder assemblies arranged on opposite longitudinal sides of the press.  The bands pass over driven and deflection rollers on opposite sides of the press gap and at least one of the rollers is adjustable so that its axis of rotation can be moved.  When realignment of one of the steel bands is required, the short stroke piston and cylinder assemblies are operated on one side of the press to reduce pressure on the band at that side, and then the axis of rotation of the adjustable roller is moved to cause the desired realignment.  In this way, stretching and deformation of the band during realignment can be avoided.

Title: Combination crankcase gasket/baffle
Inventor: BONDE KEVIN G
IPC: F02B75/02
Filed: 1992-03-19
Granted: 1993-10-05
Abstract: ABSTRACT An improved crankcase gasket, for use in an internal combustion engine with a vertical crankshaft, having web portions that substantially cover the oil sump.  The construction of the crankcase gasket baffles oil thrown around the inside of the engine by mechanical turbulence and prevents excess oil from reaching the cylinder bore.  Gasket material under the valve spring box drain operates as a check valve and eliminates the need for an expensive valve stem valve.  Oil temperature is reduced with an increased ability for engine operation at greater angles of crankshaft tilt from vertical.

Granted: 1998-12-22
Abstract: An end cap for a filter element comprises first and second concentric components of a thermoplastic material. The first of the components forms a side wall and a base of a peripheral groove of the end cap while the second of the components forms a second side of the peripheral groove. The first and second components are connected by a weld extending around the components in the region of the peripheral groove. The weld may be an ultrasonic weld. This prevents distortion of the components at high temperatures by strengthening the composite while allowing use of lightweight inexpensive components that have smooth sealing surfaces with no injection mould parting lines.
