Patent DE-2512315-A1 (DE)
Title: Continuous solid fuel gasification plant - with loop contg. dryer reactor and final ash treatment sections
Inventor: HAND JOHN WEEMS
IPC: C10J3/48
Filed: 1975-03-20
Abstract: A gasification plant for the production of synthesis gas from coal and other fuel includes a dryer section which receives the moist carbonaceous fuel and hot synthesis gas from the reactor section. A final treatment section receives a gas containing steam and oxygen, and a residue containing hot ash from the reactor section. The reactor section is charged with dry carbonaceous particles from the dryer section and with gas containing hot steam and oxygen from the final treatment section to produce a reaction for a yield of hot synthesis gas and a residue containing ash. This method is suitable for a wide variety of fuels from coal to wood waste and urban refuse. It maximizes the production of carbon monoxide and hydrogen and minimizes the production of coal tar, acids and other condensable by-products. The inexpensive synthesis gas is a substitute for natural gas and can be used in the manufacture of methane, methanol or ammonia.

Title: Disposable baby's napkin with longitudinal pleats - with inwardly facing folds of pleat abutting
Inventor: FISCHER JOHN L
IPC: A61F13/15
Filed: 1975-04-09
Abstract: A disposable baby's napkin comprises a waterproof back, a hydrophobic face sheet and an absorbent pad impregnated with a volatile matl. sandwiched between them. The combination is formed into a pleated configuration in the crotch region by a plurality of longitudinal folds which define a pair of opposed portions which extend inwardly into abutting relationship. The pad is narrower than the back sheet and the face sheet is of inter. width. The edges of the back sheet are folded over the extending portions of the face sheet but still terminate outwardly of the pad. The folded over area in the crotch region prevents the loss of volatile matl. which may be a perfume. Additionally the shaping of the napkin in the crotch region prevents undue chaffing of the baby's skin.
