Title: High grade polyethylene paper
Inventor: EVANS ROBERT JOHN
IPC: A47L9/14
Filed: 1993-11-05
Abstract: A process for producing high grade polyethylene paper on conventional continuous wet-lay papermaking equipment. In particular, the process comprises preparing a furnish of 75-99 wt. % oriented polyethylene pulp, 0.5-15 wt. % fibrous stabilizing agent and 0.5-10 wt. % strengthening agent and depositing the furnish on the forming screen of a conventional wet-lay papermaking machine. The resulting waterleaf sheet is dried on heated drying cans and then thermally bonded to provide a high grade polyethylene paper having high dry strength and toughness, exceptional dimensional stability and superior uniformity (i.e., no holes).

Title: Automatic pinsetter with baffle at elevator entrance
Inventor: ROCHEFORT LUCIEN
IPC: A63D5/08
Filed: 1995-06-16
Abstract: In an automatic pinsetter having an elevator mechanism for receiving bowling pins seriatim at a lower entrance portion from a pit area at a rear end of a bowling alley and for transporting the same upwardly for discharge at an upper end portion, a frutso-concial baffle is provided and is suspension mounted forwardly of the elevator mechanism and above a rearwardly moving conveyor. Fallen bowling pins in indiscriminate arrangement proceed rearwardly on the conveyor beneath a bridge which obstructs rearward ball movement and passes prone bowling pins only. Left and right hand guides cooperate with the baffle to define left and right hand entry passageways for the bowling pins in rearward movement to the entrance of the elevator mechanism. The passageways are insufficient in width to accommodate the side-ways passage of bowling pins. The baffle is also free to move in any direction over a limited degree of movement. The elevator mechanism receives bowling pins on forwardly open shelves with the bowling pins in a side-ways attitude and the shelves are equally adapted for the accommodation of bowling pins with their "butt" end portions disposed leftwardly or rightwardly.

Patent CA-2154064-A1 (CA)
Inventor: CACACE ANTONIO GIORGIO
IPC: B22F3/02
Filed: 1994-01-17
Abstract: A method is disclosed of producing a corrosion resistant product from a billet comprising a core of finely divided ferrous swarf compacted into briquettes in a stainless steel jacket and in which the billet is heated to a temperature at which it becomes sufficiently plastic to be worked into a finished or semi-finished product by an operation such as rolling. An additive is pre-mixed with the swarf which, when the billet is heated, reacts to form an atmosphere inside the jacket which displaces or prevents the formation of carbon dioxide and/or other gases which at elevated temperatures would oxidise the stainless steel to form chrome oxides at the interface between the jacket and the core. The additive is preferably in powder form. Examples of suitable additives include urea and ammonium chloride.
