Patent CA-2103631-C (CA)
Inventor: MACKEY JAMES C
IPC: B21D1/10
Filed: 1993-08-09
Granted: 1997-11-18
Abstract: An apparatus for straightening a propeller has an arbor press with two opposed inner surfaces. The opposed surfaces are spaced apart a sufficient distance to allow a propeller to fit between them with one opposed surface extending beyond the second opposed surface. Two pats are mounted on the first inner surface to support the propeller during the straightening procedure. One or both of the pads may be adjustable to more precisely locate the points of pressure that will be applied to the propeller to straighten it. A ram is mounted on the second inner surface to apply pressure to the propeller. A reinforcing ridge may be attached to the outer surface of the arbor press to provide rigidity during the propeller straightening procedure. To allow precision manipulation of the device under water, a floatation collar is fixed to the arbor press or the reinforcing ridge. The floatation has sufficient buoyancy to counteract the weight of the apparatus when under water. To prevent instability in the apparatus when under water, the floatation collar is positioned so that the center of buoyancy substantially coincides with the center of gravity. In one embodiment, a pair of reinforcing ridges and a cover may be used to define a water-tight enclosure. The pair of ridges provide reinforcement and the water-tight enclosure provides additional buoyancy. In operation, a single diver may manipulate the apparatus so that a bent portion of the propeller is between the opposed inner surfaces of the arbor press so that one side of the propeller rests against the pads. The ram is activated and the piston head of the ram applies pressure to the other side of the propeller to straighten the propeller. The apparatus may be manipulated by a single diver and eliminates the need for dry-docking a ship to straighten the propeller thus reducing the cost of repair and speeding up the repair process.

Abstract: Tissue sheets, such as are useful for facial or bath tissue, can be embossed with a fine scale embossing pattern to increase bulk with a minimal loss in strength. The fine scale embossing pattern contains at least about 15 discrete intermeshing embossing elements per square centimeter (100 per square inch) and can enable the tissue manufacturer to produce premium quality tissues having adequate softness, bulk and strength from conventional tissue basesheets without layering or throughdrying equipment. Depending on the starting basesheet material, tissues having a unique balance of properties can be produced, especially for conventional wet-pressed basesheets.

Title: Process for preparing a concentrated beer flavor product
Inventor: DONCHECK JAMES ALLAN
IPC: C12G3/02
Filed: 1993-02-04
Granted: 1996-08-06
Abstract: A process for forming a beer flavored concentrate by germinating barley (e.g., in the presence of the enzyme promoting agent gibberellic acid) to produce a green malt of approximately 43% moisture content that is heated in a closed container at 85° to 95°C for 2 to 6 hours (i.e., raising the internal bed temperature to 70° to 89°C for one half to 3 hours) to reduce amylolytic enzyme activity. By kiln drying in an opened container (e.g. at 50° to 65°C for 12 to 18 hours) an amylolytic enzyme deficient green malt of 3.5 to 5.5 wt.% moisture content is produced. This dried malt when used to make a mash (e.g. upon grinding and the addition of brewing water) results in the preparation of a wort that when boiled and pitched with brewers yeast can be fermented by conventional methods. The fermented wot can be diluted with water to yield a malt beverage containing less than 0.5 volume % alcohol and less than 40 calories per 12 ounces or alternatively concentrated by vacuum evaporation, freeze concentration, spray-drying and/or freeze drying to produce an intense beer flavored product.

The diaper (10) and the monitor (20) are constructed so that there is a threshold level of liquid which, when deposited in the diaper, will effect a color change in the indicator (24). A quantity of liquid which is below the threshold will not effect a color change in the indicator (24) and a quanti-ty of liquid which is above the threshold will effect a co-for change in the indicator (24).

Abstract: A process and device are disclosed for producing a package of elongated winding material. A winding bobbin (50) has a conical winding core (52) and a first detachable flange (53) arranged at the side of the winding core (52) having the smaller diameter, and a second flange (54) arranged at the other side of the winding core (52). The winding bobbin (50) is held in a winding device by means of bobbin holding members (103, 104) which center both flanges (53, 54) and are supported on their surface opposite to the winding core (52). The elongated winding material (D) is then wound on the bobbin (50), the winding process being controlled in such a way that a predetermined type of bobbin is obtained. In particular when a plastic bobbin (50) is used, the package is easy to transport but is at the same time very resistant, so that additional packaging measures may be dispensed with. Packaging waste may thus be almost entirely avoided.
