Title: Device and method for composite flow enhanced floatation separation
Inventor: ZHANG HAIJUN
IPC: B03D1/14
Filed: 2019-10-08
Granted: 2021-08-12
Abstract: : 
Disclosed is a device and method for composite flow enhanced floatation separation, 
which is applicable for floatation of difficult-to-float fine mineral particles or coal particles.  
The device includes a circulating pump, a turbulent flow mineralization reactor, a floatation 
tank, a circulating flow floatator and a middling-tailing separator. The turbulent flow 
mineralization reactor is a cylinder. Provided around the cylinder are a plurality of cross flow 
pre-mineralization tubes, a plurality of impinging stream pre-mineralization tube, a pulp 
distribution tube and a pulp jet tube. The cross flow pre-mineralization tubes are tangentially 
connected to the cylinder. After feeding pulp into the floatation tank, easy-to-float particles 
rise rapidly and are discharged from a concentrate discharge tube; a part of medium floatable 
particles, after being sorted by the circulating flow floatator at the bottom of a column, float 
up to the foam tank and are discharged from the concentrate discharge tube; a part of 
difficult-to-float particles, after being sorted by the circulating flow floatator, is discharged 
from the tank as a tailing, and the other part of the difficult-to-float particles is fed into the 
turbulent flow mineralization reactor via the circulating pump, efficiently mineralized and 
then fed into the circulating flow floatator to perform cyclic sorting. The invention integrates 
high-speed impinging streams, cross flows and circulating flows and has remarkable effects in 
use and high efficiency in sorting.

Title: A method and apparatus for generating, storing and using hydrogen
Inventor: HIGGINBOTHAM PAUL
IPC: F03D9/19
Filed: 2021-07-23
Granted: 2023-02-23
Abstract: Hydrogen is produced by electrolysis of water using electricity generated from a renewable energy 
source such as wind and/or solar radiation, compressed in a multistage compression system and 
consumed in at least one downstream process. Supply of hydrogen to the downstream 
process(es) fluctuates with demand and/or the availability of the renewable energy source. In 
order to accommodate such fluctuations, excess hydrogen is stored during periods when 
production of hydrogen exceeds that required by the downstream process(es) so that, during 
periods when demand exceeds production, hydrogen is removed from storage and, after suitable 
pressure reduction, fed to the downstream process(es) via a stage of the multistage compression 
system.

Abstract: Known telecommunication systems like a DECT-system comprising a base-station and a handset or like a Digital Home Network system comprising a controller and several devices or a car radio system comprising a car radio and a front are based upon an authorisation process for introducing a new device or for coupling an already introduced but decoupled old device to said telecommunication system. Such authorisation process, which often is user-unfriendly, can be partially or even completely avoided by either using the result of an old identification process or by using a new identification process for identifying a user, which can be done in a much more user-friendly way. <IMAGE>
Patent JP-3995033-B2 (JP)
IPC: B65D47/20
Filed: 1998-08-21
Granted: 2007-10-24
Abstract: An improved no-spill cup construction and valve assembly which provides an extremely secure seal against accidental liquid flow from the cup spout. The act of sucking at the cup spout creates negative pressure or a partial vacuum against a valve near the spout, causing the valve to invert which unblocks an opening in the valve. When the opening is unblocked, liquid can flow freely through the valve and spout. When not in use, the valve sits in a resting, closed position, with the valve pressed against a center seal-off, sealing off the opening in the valve assembly. The closed position provides an extremely secure seal against fluid leakage, such that inadvertent spills or even deliberate attempts to force liquid outside of the cup, such as by turning the cup upside down, or shaking the cup, are ineffective. The cup assembly further allows liquid flow to be regulated between regular or maximum flow and minimal flow levels or rates by rotating the position of the valve assembly in the cover of the cup.

Patent JP-3763515-B2 (JP)
IPC: H04L47/765
Filed: 1999-07-06
Granted: 2006-04-05
Abstract: A method is provided for communication between a plurality of stations in a communication network using media access protocol, in which medium access is granted to stations obtaining a successful reservation of the medium and in which data transmission verification is performed by the protocol within the reservation. In the method a station sends a request message on the communication medium for a reservation of the medium to a recipient station in the network. The recipient station sends a reservation confirmation message back to the sending station which receives it and responds to the reservation confirmation message by sending an ordered sequence of data frames to the recipient station. After sending the ordered sequence of data frames the sending station sends an end of transmission message to the recipient station, which replies by sending back an end of transmission confirmation identifying the number of frames received in their original sequence. If the number is not correct remedial action can be taken by the sending station to resend missing data. Address conflict resolution is also provided by another aspect of the invention. The invention has embodiments which handle unicast and groupcasting transmissions.
