Abstract: A medical waste collection system for collecting medical waste material, and a manifold for filtering the waste material and/or coupling a suction tube to the system. The system may include a receiver in which the manifold is configured to be inserted in a proximal direction to facilitate an inlet mechanism moving correspondingly in the distal direction. The manifold may include an arm, a spine, a lock element, and/or a catch each having a surface with a relative position in the proximal-to-distal direction. The rim and the catch may be spaced apart by a void, and the rim may be positioned below the catch. The housing may include a body portion, a first leg extending proximally from the body portion, and a second leg spaced apart from the first leg to define the void. The rim may be on the first leg, and the catch may be on the second leg.

Abstract: A manifold for coupling a suction tube to a medical waste collection system. A housing includes a body portion, and first and second legs extending from said body portion. An inlet fitting is for coupling to the suction tube. An arm extends outwardly from said housing and includes a proximally-directed surface. A lock element extends outwardly from said housing and includes a distally-directed surface. A spine extends outwardly from said housing and includes a proximally-directed surface. A catch may include a distally-directed surface. A rim of the first leg defines an outlet opening, and the catch and the rim are spaced apart by a void between the first and second legs. The housing may define a manifold volume, and a filter element may be disposed within the manifold volume. A radiofrequency identification (RFID) tag may be at least partially positioned on said second leg.

Abstract: A manifold including a filter element for filtering medical waste. A housing may include a rim having a width larger than a height to define a non-circular outlet opening. The housing may include body portion, a first leg extending proximally from the body portion, and a second leg spaced apart from the first leg to define a void. The rim may be on the first leg, and a radiofrequency identification (RFID) tag may be at least partially disposed on an upper wall defining the second leg. A spine may include a proximally-directed surface positioned proximal to a distally-directed surface of a lock element and distal to a proximally-directed surface of an arm. The proximally-directed surface of the spine may be a ramped surface. A seal may be coupled to the rim and include a seal body shaped to cover the outlet opening.

Abstract: The present invention relates to a method for the galvanic deposition of zinc and zinc alloy coatings from an alkaline coating bath with a reduced degradation of organic bath additives. An electrode that contains metallic manganese and/or manganese oxide and is insoluble in the bath is hereby used as the anode, and is produced from metallic manganese or a manganese-containing alloy, the manganese-containing alloy comprising at least 5% by weight of manganese, or is produced from an electrically conductive substrate and a metallic manganese and/or manganese oxide-containing coating applied thereto, or is produced from a composite material, with both the metallic manganese and/or manganese oxide-containing coating and the composite material comprising at least 5% by weight of manganese, based on the total amount of manganese resulting from metallic manganese and manganese oxide.

Abstract: A manifold including a filter element for filtering medical waste. A housing may include a rim having a width larger than a height to define a non-circular outlet opening. A catch including a distally-directed surface may be positioned proximal to a proximally-directed surface of an arm, proximal to the rim, proximal to a proximally-directed surface of a spine, and proximal to a distally-directed surface of a lock element. The proximally-directed surface of the spine may be a ramped surface. The rim and the catch may be spaced apart by a void, and the rim may be positioned below the catch. The housing may include body portion, a first leg extending proximally from the body portion, and a second leg spaced apart from the first leg to define the void. The rim may be on the first leg, and the catch may be on the second leg.

Abstract: A waste collection unit is provided that comprises a vacuum pump and smoke evacuation system including a blower and blower motor. The vacuum pump, the blower, and the blower motor, create noise. This noise is attenuated in first and second sound attenuating enclosures for the vacuum pump and the blower and blower motor. A cleaning system is also provided 100 with rotating liquid delivery devices. An actuator is operatively coupled to the liquid delivery devices to rotate the liquid delivery devices.

Abstract: Precipitations of nitrohydroxyaromatic salts out of the nitrated crude products obtained in the nitration of aromatic compounds after alkaline scrubbing, for example mononitrotoluenes, are prevented by contacting the nitrated crude products with an acidic ion exchanger. The nitrated crude products are preferably selected from a feedstream to a distillation column, a bottoms circulation stream of a distillation column and a feedstream to a vaporizer.

Abstract: The invention relates to a process for the continuous preparation of toluenediamine by liquid-phase hydrogenation of dinitrotoluene by means of hydrogen in the presence of a suspended, nickel-comprising catalyst in a reactor with a product isolation unit downstream of the reactor to give a product output from the reactor comprising a liquid phase comprising toluenediamine and dinitrotoluene, in which the nickel-comprising catalyst is suspended, wherein the concentration of dinitrotoluene in the liquid phase of the product output from the reactor in the region between the reactor and the downstream product isolation unit is set to a value in the range from 1 to 200 ppm by weight, based on the total weight of the liquid phase of the product output from the reactor.
