ABSTRACT A novel process for preparing a diaphragm-deposited activated cathode for use in a chlor-alkali cell is disclosed; the process involves placing an activated cathode in a slurry of fibrous material and depositing a uniform mixture of the fibrous material onto the cathode by means of a vacuum; most importantly, the invention involves heat-treating the activated cathode in an inert atmosphere, such as a nitrogen atmosphere or a reducing atmosphere, such as a hydrogen atmosphere, during the baking or sintering of the diaphragm; diaphragm-deposited activated cathodes prepared according to this invention exhibit better adhesion and stability than those which are prepared using conventional techniques; this, in turn, permits sustained operation in a chlor-alkali cell at a lower voltage for substantial energy savings.

Notepad forming method and apparatus therefor

Theres is disclosed a device (10) for manufacturing a notepad (15) comprising a stack of sheets, a first side of each sheet having an adhesive to attach the first side to a reverse face of a sheet immediately facing said first side in said stack. The device (10) including a sheet feeder (20) for loading one or more loose sheets (24) of similar dimensions with the reverse face of each sheet (24) in said stack facing in the same direction and feeding each said sheet downstream of said device (10). A cutting means (40) is provided to cut each sheet (24) or a number of said sheets (24) to predetermined dimensions. An adhesive applicator (60) applies adhesive to a portion or portions of the first side of each sheet (24). A stacking means (100) stacks the cut sheets one on top of the other whereby a forming means (120) forms the cut sheets together to form the notepad (15).

Etchant, method of etching, laminate formed thereby, and device

An etchant including a halogenated salt, such as Cryolite (Na 3 AlF 6 ) or potassium tetrafluoro borate (KBF 4 ), is provided. The salt may be present in the etchant in an amount sufficient to etch a substrate and may have a melt temperature of greater than about 200 degrees Celsius. A method of wet etching may include contacting an etchant to at least one surface of a support layer of a multi-layer laminate, wherein the support layer may include aluminum oxide; or contacting an etchant to at least one surface of a support layer of a multi-layer laminate, wherein the etchant may include Cryolite (Na 3 AlF 6 ), potassium tetrafluoro borate (KBF 4 ), or both; and etching at least a portion of the support layer. The method may provide a laminate produced by growing a crystal onto an aluminum oxide support layer, and chemically removing at least a portion of the support layer by wet etch. An electronic device, optical device or combined device including the laminate is provided.

System and method to handle media transmission in mission critical (mc) system

The disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. In the disclosure, a system and a method to handle media transmission in the Mission Critical (MC) systems or MC Video system are provided. According to the system and the method, wastage of network resources can be avoided and other participants in the group can be given chance to transmit important data as maximum number of transmissions at a time in a group call are limited by network capacity. Accordingly, efficiency of the MC Video system can be improved.
