Title: Process for injection molding polyethylene terephthalate
Inventor: KODA HIDEAKI
IPC: C08L67/00
Filed: 1996-09-25
Abstract: There is provided a process for injection molding a preform for stretch blow molding a thin-wall vessel such as a bottle using amorphous polyethylene terephthalate (A-PET) as a molding material, wherein a required amount of crystallized polyethylene terephthalate (C-PET) is added to the A-PET.     The resulting mixture material can be easily plasticized to increase the IV value of the molding material to a value higher than that of A-PET so as to injection mold the preform. A-PET which is hardly usable as a molding material for stretch blow molding due to its low IV value is made usable as a molding material for stretch blow molding by increasing its IV value making use of plasticization at the time of injection molding.

Patent CA-2186983-A1 (CA)
Inventor: MOTOOKA EIJI
IPC: G03B27/60
Filed: 1996-10-02
Abstract: A suction feeder which can feed photosensitive material sheets of different sizes with the suction force applied thereto kept substantially constant.  The suction feeder has a motor-driven endless suction belt having numerous suction holes formed uniformly over the entire area thereof.  A suction box is provided under the carrier side of the suction belt.  It has a belt supporting plate formed with suction holes.  A motor-driven blower is connected to the suction box.  The suction pressure applied to the suction holes of the suction belt through the suction holes in the belt supporting plate is reduced by reducing the revolving speed of the blower-driving motor with increase in the size of the photosensitive material sheet fed onto the carrier side of the suction belt.  It is thus possible to apply substantially constant suction force to photosensitive material sheets of different sizes.

Patent CA-2192580-A1 (CA)
Inventor: BLOMBERG TORSTEN
IPC: B23B41/02
Filed: 1995-05-31
Abstract: A drill primarily intended for ejector drilling is made of one single piece, in order to avoid unsoundness that arises when welding and to avoid weld joint gaps in which a chip may easily get wedged.      Moreover, the drill is provided with a turned-out chip space (13) in order to as far as possible avoid chip jamming. The inserts are preferably placed tangentially, which simplifies their mounting. In principle, the inserts are semi-circle formed and this simplifies both their pressing and the making of the insert pockets.

Patent CA-2197622-A1 (CA)
Inventor: MUELLER NORBERT
IPC: A01B59/00
Filed: 1997-02-14
Abstract: The invention relates to a lifting rod for the lower steering arm of a tractor.  At the ends of the lifting rod there are attached connecting elements in the form of a connecting yoke 6 and a ball joint 7.  The connecting yoke 6, by means of a threaded rod 9,  is threaded into a threaded bore 10 of a tubular rod element 11.  The rod element 11 is received in the housing bore 21 of the housing 8 so as to be movable along the longitudinal axis 17.  The rod element 11 and the housing 8 are able to assume two different positions relative to one another, with the lifting rod length being fixed in one of said two positions.  In the other position, both may assume a floating relationship relative to one another.  To allow the lifting rod length to be set even when the lifting rod is in the mounted condition and to ensure that both parts do not change their respective positions even when in use, it is proposed that in the rigid position, the plug-in pin 24 engages a recess 13 in the rod element, so that support is provided in the shortening direction and in the direction of rotation, whereas for the direction of extraction there are provided stops which prevent any lengthening.   After the plug-in pin 24 has been extracted, the rod element 11 can be turned by 90°, thus enabling the plug-in pin to pass through the slot 14 in the rod element 11; the lifting rod length is shortened, but rotation is prevented.

Patent CA-2214308-A1 (CA)
Inventor: MACINTYRE KENNETH REID
IPC: F24H3/06
Filed: 1997-08-29
Abstract: The present invention provides a forced air furnace integrated with a ventilator having a pair of regenerative bed heat exchangers. The heat exchangers alternate between heat recovery and heat release modes such that when one heat exchanger is in the heat release mode the other is in the heat recovery mode. Valve means comprising a pair of valve members, in the preferred embodiment plastic discs, fixed on a common shaft to control the alternate switching of recovery and release modes between the two heat exchange beds. The valve members are mounted adjacent to inlet and outlet partitions containing the inlet and outlet ports, respectively, in communication with the heat exchange compartments, and are provided with valve openings which, by rotating the shaft, are brought into alignment with the inlet and outlet ports to direct the fresh and stale air streams through the heat exchange beds. Because their rotational motion allows the valvemembers to remain in constant contact with the inlet and outlet partitions there is no opportunity for leakage between the fresh and stale air streams. Moreover, since both valve members are mounted on a common shaft, construction of the valves is considerably simplified and a small servo motor can be used to drive the valve means. The heating and ventilating functions are integrated by providing a damper upstream of the ventilator fresh air outlet to the furnace supply elbow, so that the low energy fresh air blower in the ventilator can be active when the high energyfurnace blower is inactive without resulting in backflow from the ventilator into the furnace. The damper is biased by gravity to a closed position such that the force of air from the furnace air blower is sufficient to open the damper, the biasing force being controlled by an external counterweight which can be adjusted to ensure that the damper remains closed when the furnace blower is off, yet the furnace blowerdischarge can open the damper with minimal resistance.
