Abstract: A two stage sulfonation system includes a mixing tank, a retention tank, a thickening press, a pressurized vessel, and a liquor recovery press in series relation.The system is designed to receive mechanical pulp, in a slurry form, first introduced into the mixing tank simultaneously with a metered charge of sodium sulfite solution from the holding tank, the sodium sulfite content of which is at a level from about 40 to about 200 g/l. The solution is mixed into the slurry to provide a relatively uniform and intimate contact thereof with its fiber content. This slurry is transferred to the retention tank and there held subject to a sub-boiling temperature between 140 to 210 degrees F., producing a first stage sulfonation of the fiber content. The slurry is then passed to the pressurized vessel, in the course of which it is subjected to a pressing action, extracting liquor which inherently contains a majority of the original sodium sulfite charge directed to the mixing tank.

Abstract: In order in a facade comprising hollow uprights and hollow upper and lower transverse crossbars to be able to dispense with an expensive air-conditioning installation, a cross-stream blower is arranged under a railing crossbar. Over the cross-stream blower there is either provided a star ribbed pipe or the railing crossbar is constructed in several parts and provided with laminations the function of which is to serve in the pre-cooling or pre-heating of air drawn from a room of the building by the cross-stream blower, the pre-cooling or pre-heating taking place as the air is discharged from the blower and before it is sent back into the room. Pre-heated or pre-cooled air may be returned to the room by way of the railing crossbar, by way of and from the hollow uprights or by way of and from the upper transverse crossbar. A filter provided in advance of the cross-stream blower inhibits the passage of any health-hazardous dust or bacteria from reaching the blower or being transmitted back into the room.

Abstract: A bait station for rodents, an elongate, hollow tubular structure having a single opening to and from its interior. This station is formed of tubing fabricated, preferably, of tough, corrosion, weather and distortion resistant plastic such as a polyvinylchloride. Its preferred configuration provides that one end portion of its tubular structure is enlarged as to its cross sectional area to define a bait chamber the entrance to and exit from which is limited to a single passage, defined by its remaining length the remote end of which provides the single opening to and exit from the passage. The cross sectional area of said passage is made substantially less than that of said chamber. This precludes entrance by animals larger than that of the target rodents. Preferred bait embodies a non-poisonous anti-coagulant, ingestion of which produces a breakdown of the rodent's life support system and its expiration, but not until some time after the rodent leaves the vicinity of the bait station.
