Patent CA-2202456-A1 (CA)
Inventor: BIZON ROMAN
IPC: B30B1/32
Filed: 1997-04-11
Abstract: A portable hydraulic press has a rectangular frame comprising a head plate, a base plate, and two side plates. Each side plate has an inwardly-projecting flange attached to each free edge thereof. A platform is slidably positioned inside the side plates and flanges of the frame such that the platform may slide either toward or away from the head plate. A conventional hydraulic bottle jack of selected capacity is positioned inside the frame, with its base against the base plate, and with the end of the ram of the jack engaging a retaining cup mounted to the underside of the platform. Actuation of the jack causes the ram to extend outward from the jack, thereby moving the platform toward the head plate, and compressing a workpiece positioned between the platform and the head plate.

Title: Apparatus and method for a modular lifting and shoring system
Inventor: VANDERKLAAUW PETER M
IPC: B66F1/00
Filed: 1998-02-18
Abstract: The present invention provides a plurality of block-like building elements which may be bolted to each other to form a variety of support structures without the use of heavy hoisting equipment. Some of the building elements have a generally U-shaped appearance when viewed in plan, i.e., the building elements are open or slotted on one side so that a hydraulic cylinder or other lifting device may be inserted into the interior of the building element, or into a post formed from a stack of connected building elements. The lifting device may be used to preload the support structure. Advantageously, the lifting device may be used to progressively lift a load to a higher elevation by elevating the load a sufficient distance to enable the addition of an additional building element. The lifting device may then be repositioned within the structure for further elevating the load.

Title: Steering cylinder with engine-clearance features and method for making the cylinder
Inventor: WAGNER JERALD G
IPC: F02B61/04
Filed: 1996-08-30
Abstract: A hydraulic cylinder (10) for steering a tiltable boat engine (23) includes a cylinder housing (11) with first and second housing ends (67, 69). The cylinder (10) is characterized in that at least the first end (67) includes a reduced-dimension relief portion (71) preventing the cylinder first end (67) from contacting the engine (23) when the engine (23) is tilted. A new method for making such a cylinder (10) includes the steps of forming a cylinder housing (11) having a mid-section (65) and first and second housing ends (67, 69) and shaping a relief portion (71) at the first end (67). The cylinder first end (67) is thereby prevented from contacting the engine (23) (and, particularly, the engine stem bracket (73)) when the engine (23) is tilted. The invention also involves unique manufacturing and assembly techniques.
