Filed: 2012-09-19
Abstract: An embossing head for use in a rotary printing press has a raised embossing stamp, a constraining means for constraining motion of the embossing stamp along a radial direction, and adjustable positioning means for stopping radially downward motion of the embossing stamp at an adjustable lowermost position for determining an adjustable radial height of the raised embossing stamp. A number of embossing heads may be mounted independently to annular collars of the press to enable free positioning of the corresponding embossments in both dimensions of the sheet material. The adjustable positioning means enables fine height selection and adjustment of each embossing stamp individually so as to enable and facilitate the production of embossments on sheet material within specified tolerances reliably over numerous print cycles.

Title: System and method of resolving a domain name
Inventor: BULLEY CHRISTOPHER
IPC: G06F40/00
Filed: 2013-07-04
Abstract: A method of resolving a domain name that includes a non-LDH character, involves a client computer receiving a domain name update notification for a first computer server that has a LDH domain name comprising at least one character but excluding non-LDH characters. In response, the client computer downloads a configuration payload from a registration server that maintains an association between the first computer server and a second computer server. The configuration payload links the first computer server to a non-LDH domain name associated with the second computer server and configures the client computer to determine an identification of the second computer server from the first LDH domain name. The non-LDH domain name has at least one non-LDH character. The client computer uses the identification of the second computer server to establish a communication session therewith while displaying the associated non-LDH domain name.
Patent CA-2883101-A1 (CA)
Inventor: MARTEZ VITA
IPC: C02F9/02
Filed: 2012-09-04
Abstract: A modular, transportable desalination system utilizes nanofiltration to treat the reject stream from reverse osmosis to increase product water production and to reduce the disposal of at least partially treated contaminated water. Prior to reverse osmosis, the contaminated water is pretreated, typically by coarse filtration, ultrafiltration, dechlorination and removal of scale-causing ions. The product water is disinfected prior to use as potable water. Further, disinfection can be part of the pretreatment process at any point in the system prior to reverse osmosis. Additional product water is produced by treating the reject streams, typically from the membrane process in an evaporator/distiller unit which heats the reject streams vessel to produce steam which is then cooled to produce product water. Concentrated brine from the evaporator/distiller unit may be sent to a crystallizer for forming salt crystals therefrom or allowed to dry under ambient conditions for disposal.

Title: Device and method for regulating and controlling the gas pressure
Inventor: KIRCHMEIER MARTIN
IPC: C10B27/06
Filed: 2013-10-10
Abstract: The present invention relates to a device and a method for regulating and controlling the individual gas pressure of individual ovens of a coke oven battery, in the case of which a rising- pipe bend projects, preferably from above, into a collecting main. The lower end thereof is associated with an immersion pipe via a water labyrinth seal. The immersion pipe is supported such that it is vertically adjustable by means of an actuator, and an immersion cup is located preferably below the immersion pipe. The device aims at allowing the gas pressure to be regulated or controlled easily and reliably. This is accomplished in that the rising-pipe bend has arranged therein a sleeve, the lower end of which is connected via at least one conduit to the water labyrinth seal, and in that a water supply for feeding the water labyrinth seal, and the actuator are provided at the top, outside the rising- pipe bend. Regulation of the gas pressure is accomplished by the different immersion depths of the immersion pipe and the constant water level in the immersion cup. The plane overflow edge of the immersion cup improves the regulating characteristics and the flowing off of the gas and defines the constant water level.
