Abstract: An injection cooler for cooling hot steam in a pipeline has an injecting device that has multiple injection nozzles. The cooler includes a regulating body connected to a coolant supply. The regulating body is equipped with a valve arrangement to regulate coolant feed to the injection nozzles. Coolant feed lines are provided between the injecting device and the regulating body with a separate coolant feed line being provided for each injection nozzle. Ends of the coolant feed lines of the injecting device are secured to a first flange plate which can be secured to a surface on the injecting device. Ends of the coolant feed lines associated with the regulating body are secured to a second flange plate which is secured to a receiving surface of the regulating body. The injecting device has a tubular mixing portion with a de Laval nozzle-type longitudinal section along a longitudinal axis.

Abstract: The invention relates to equipment (10) feeding polymers into a fluid flow which is guided within a pipeline (20) and comprising a control (40) which may be hooked up to a polymer supply line (42), further comprising several feed conduits (70) which are configured between the said control and said pipeline and move the polymers from the control (40) to the pipeline (20). The control (40) of the equipment (10) furthermore includes a valve system (50) designed in a manner that a defined number of feed conduits (70) can be opened or closed. In addition, one static mixer (80, 81) is configured at least in segment(s) in each feed conduit (70). This equipment makes it possible to feed polymers, in particular polymers in aqueous solution and of high molecular weights, at a predetermined pressure and at defined rates into a fluid flow without thereby destroying the molecular chains of said polymers.

Abstract: A multiple electrical outlet box which prevents unauthorized use of connected electrical devices. The multiple electrical outlet box includes a cover which is used to enclose electrical plugs which are connected to multiple outlets, thereby preventing their removal. A lock assembly including an attached mechanical latch locks the cover over multiple electrical outlets in response to a key. An electrical switch is provided which disables power to all enclosed outlets in response to rotation of the key lock and therefore in response to the attached mechanical latch. The cover encloses plugs connected to electrical outlets and therefore secures them against removal. The electrical switch disables power to all enclosed electrical outlets and connected electrical plugs.
