Patent CA-2066694-A1 (CA)
Title: Water absorption bag
Inventor: LEONE DEMETRIO
IPC: E02B3/04
Filed: 1991-05-06
Abstract: Abstract The water absorption bag (18) has an absorption pad (20) in which a superabsorber is homogeneously sprinkled into a pulp of cellulose fibres, and an absorption core (21) formed from at least one layer is made with a tear-resistant, liquid-permeable outer shell (22).            The cellulose fibres, preferably recycled fibres, are mixed with fibres of thermoplastic to form a homogeneous pulp in a weight ratio of at least 4:1, which pulp is shaped before or after three-dimensional homogeneous sprinkling of the superabsorber and is subjected to a heat treatment partially melting the plastic to bind the fibres at many points. The cellulose and plastic fibres joined like a net thus have an increased but resilient dimensional stability. The outer shell (22) may be designed to be openable.            The absorption pad (20) and/or the outer shell (22) preferably comprise integrated means for accommodating an insert (42) increasing the specific weight separately from the pulp with the superabsorber. The outer shell advantageously consists of natural fibres, preferably of sisal or jute fibres.            The water absorption bags (18) serve to protect against effects of water during fire, flooding, pipe leaks and the like.    (Figure 6)

Title: Penile implant with lengthening cylinder
Inventor: COWAN TIMOTHY
IPC: A61F2/26
Filed: 1992-07-22
Abstract: A penile prosthesis with a two piece inflatable cylinder that provides significant lengthwise expansion of a male penis. The cylinder has an inflatable bellows attached to an inflatable member and a sheath that extends from a base member. The bellows is attached to the base member and the sheath is connected to the inflatable member, such that the sheath will stretch when the bellows is inflated. The sheath surrounds the bellows. The sheath is constructed from an elastic material that can expand up to 100% of its original length. The inflatable member and bellows are connected to a pump which transfers fluid between a reservoir and the cylinder. When fluid is pumped into the cylinder, the bellows and inflatable member are inflated and the sheath is expanded, allowing the inflatable member to move into an elongated position. When the cylinder is inflated the sheath is in tension, wherein the sheath will pull the inflatable member back into a compact position when the bellows is deflated.

Title: Form drilling or turning device
Inventor: HOERMANSDOERFER GERD
IPC: B23Q5/04
Filed: 1991-12-11
Abstract: (57) Abstract The invention concerns a special device for producing by machining a multi-plicity of shaped bores or shaped external surfaces, such as squares, hexagons, el-lipses, polygons. This is done by superimposing a forced radial motion, produced by purely rolling-action elements (12, 13, 14, 15), on the rotational motion of a tool hol-der (3) in such a way that the cutting edge of a tool (23) inserted in the tool holder (3) follows the required path as the tool holder rotates. Unlike other methods, such as broaching and floating-tool broaching as well as erosion machining and milling, the device proposed enables shaped bores and external surfaces to be produced not only cleanly and to the required tolerances, but also very rapidly and simply. The form drilling and turning device proposed can be used on normal drilling and mill-ing machines and machining centres, as well as on turning machines with powered tools.

Title: Speed Measurement Device
Inventor: AMYOT ANDRE
IPC: G01P5/07
Filed: 1992-12-01
Abstract: A speed measuring device for use with shallow draft jet pump propelled boat is disclosed.  The device which includes a magnetized paddle wheel with diametrically opposed paddles having similar charges and adjacent paddles having opposite charges, is mounted in a housing adjacent a "hall-effect" device which translates the rate of rotation of the paddle wheel into a speed measurement reading due to the changes in the frequency of changes in the electrical field produced by rotation.  The present invention is different from all other speed measuring devices in that the paddles do not protrude beyond the surface of the hull of the watercraft and therefore cannot become damaged by sand, rocks, or other floating debris.  The invention includes a substantially flat base plate with a progressive recess on the underside thereof.  This progressive recess carries water to a cavity or housing within which the paddle wheel is rotatably mounted.
