Abstract: A seed envelope having a window formed with an aperture extending not only through and entirely across the front panel of the envelope from one side edge to the laterally opposite side edge but also further extending beyond the side edges and onto the back of the envelope. A transparent sheet of window material extends beyond the aperture so as to overlap the sheet of envelope material in a peripheral overlap area around the aperture. The transparent sheet is folded along the laterally opposite side edges and bonded to the front panel and envelope panels connected to the sides of the front panel. Preferably, the aperture also extends beyond the bottom fold crease and into the panel that is connected to the bottom of the front panel and is folded onto the back of the envelope. The seed content is visible from the sides of the envelope and even the rear of the envelope adjacent its side and bottom edges.

Abstract: A seed envelope includes an aperture covered by a transparent sheet. The aperture is particularly spaced from the bottom and two sides of the envelope. The aperture allows the purchaser to view the seeds which fill at least a portion of the seed envelope. In order to incorporate the transparent sheet, the envelope must be filled from the top, away from the transparent sheet and aperture.

Abstract: A method of and system for providing vascular access in a patient for hemodialysis involves attaching the distal end of an access catheter to the abdominal aorta of the patient and the proximal end of the access catheter to a portion of the patient to allow selective access to an interior portion of the access catheter. A blood-withdrawal catheter and a blood-return catheter are placed into the access catheter until their distal ends are in the patients abdominal aorta and blood may be removed and return to the aorta. When finished, the blood catheters are removed. Selective access to the proximal end of the access catheter is provided, preferably, by a cutaneous port assembly that includes a screwable cap and anti-infection cuff.

Abstract: The portable, hand held power saw having, integrally constructed therewith, an internal combustion engine to avoid the needs for any form of battery or external electrical power supply.

Abstract: Method and apparatus for cleaning a tire curing mold by immersion in liquid cleaning agent bath, wherein the complete upper assembly of the mold is immersed in the bath and slowly rotated. Super or ultrasonic energy sources are particularly located and aimed, so that in combination with the relative motion of the mold assembly relative to the sources no portion of the surfaces to be cleaned is hidden by any other part from the direct impingement thereon of the sound wave energy. Efficiency of mold cleaning is materially advanced.
