Patent CA-2082294-C (CA)
Title: Conveying device for push-type or continuous-heating furnaces
Inventor: PFLANZ RUDOLF
IPC: F16C5/00
Filed: 1992-11-06
Granted: 1996-04-16
Abstract: A crosshead shoe for the sliding transport on rails of a material to be annealed has, for the lateral guid-ing on the rails, an approximately U-shaped cross sec-tion with downwardly projecting legs.   Special glide elements are provided on the side of the glide shoe which faces the glide plane, and/or the rail, which glide elements are designed so that as little wear and friction as possible occur during the movement of the crosshead shoes.  The glide elements have glide surfaces for this purpose, the side surfaces of which glide surfaces are rounded and/or downwardly inclined, and/or the peripheral edges of which are associated with one another in obtuse angles or have a shape which is at least partially circular.  These conditions exist, for example, in glide elements with polygonal or circular surfaces, which can be arranged in one or several rows or in a honeycomb pattern.  Since important edges thus extend inclined to the direction of movement and furthermore no break-off-endangered acute edge angle exists, interferences (for example during travel over rail joints) do not act simultaneously onto the entire edge, so that edge break-offs can be substantially avoided.  A flow channel is provided between the crosshead shoe and the base of the material being annealed, through which additional hot air is blown against areas of the material shielded from the main stream by the rail and the crosshead shoe.

Title: Valve gated injection molding apparatus with a spring in the piston
Inventor: TENG ALEX C
IPC: B29C45/28
Filed: 1993-12-13
Granted: 2002-05-07
Abstract: Valve gated injection molding apparatus with a spring mounted on a central pin adjacent the head of a valve member in a spring chamber in each of the pistons.      The spring is compressed between the base of the pin and the cap of the piston to preload it. When the valve member and piston are driven forwardly to the closed position, the head of the valve member retracts somewhat into the spring chamber against the force applied forwardly against the head of the valve member by the spring. This cushions the impact of the front end of the valve member in the gate and provides for tight seating of the front end of the valve member in the gate without requiring all of the components to be made to precise tolerances with exact allowance for thermal expansion. The spring is a number of selected disc springs stacked in sets facing in opposite directions, from which the force applied to the head of the valve member is predetermined.

Title: Zero lead planer
Inventor: CROGHAN CHARLES L
IPC: B27C1/02
Filed: 1994-10-26
Granted: 2005-07-12
Abstract: A planer is improved by recognizing the source of instability of a board relative to a guidebar. An angled relationship between feed roller force the guidebar and holds the board against the guidebar. Traditional cutting heads urging the board in the opposite direction relative to that of the feed rollers, develop lateral force vectors kicking the board away from the guidebar. By establishing a zero lead relationship between the cutter heads and the board as it rests against the guidebar, the board enjoys greater stability. The disclosed apparatus further includes an air regulated top pressure plate establishing a given separation between itself and a cutter head, but accommodating abnormal operating conditions, i.e., jammed boards, by vertical movement relative to the cutter head facilitates remote actuation to quickly relieve a jammed condition. Also shown, a bearing housing for a cutter head support shaft is carried on an articulated hinge to improve manual mounting of the bearing housing upon the shaft.

Patent CA-2139905-C (CA)
Inventor: LEU WILLY
IPC: B42C9/00
Filed: 1995-01-10
Granted: 2005-06-21
Abstract: The multi-sheet, folded printed product arranged on the supporting member is penetrated by a penetration tool, from the direction of a supporting member. A pressure-exerting element acts on the printed product with a lateral compressive force. This results in a widening of the through-passage produced through the printed product. Upon withdrawal into the rest position of the penetration tool, adhesive present on the surface of the penetration tool is transferred onto the sheets in the through-passage. Once the lateral compressive force has been eliminated, the through-passage closes, which results in good distribution of the adhesive and reliable adhesive bonding.
