Patents by Inventor Dimitrios Makrakis

Dimitrios Makrakis has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9813931
    Abstract: In some examples, an apparatus may be usable in a first network and configurable to operate within a proximity of a second network that communicates traffic that interferes with data communication in the first network. The apparatus may include a calculation module configured to calculate a packet loss rate. The apparatus may include a determination module coupled to the calculation module and configured to determine whether the packet loss rate exceeds a particular threshold level. The apparatus may include a preamble module coupled to the determination module and configured to dynamically adjust a number of protective bytes included in a packet preamble in response to a determination by the determination module that the packet loss rate exceeds the particular threshold level. The protective bytes may be effective to reduce packet corruption due to turnaround time collisions between packets communicated in the first network and traffic communicated in the second network.

  • Patent number: 9723490
    Abstract: In some examples, a method may include determining whether a data packet is correctly received. In response to the data packet being correctly received, the method may include reading a received signal strength indication (RSSI) value, and based on the RSSI value, determining whether to transmit an acknowledgement (ACK) packet.

  • Patent number: 9216418
    Abstract: A method for the introduction of auxiliary grinding bodies into an agitator ball mill and for the removal of auxiliary grinding bodies from an agitator ball mill. The auxiliary grinding bodies are transported into the agitator ball mill and out of the latter via a closed circuit by means of a hydraulic conveying medium.

  • Patent number: 9010666
    Abstract: A method for the operation of a jet mill with an integrated dynamic air classifier, wherein particles are fed as grinding stock into a grinding chamber of the jet mill and are ground there into ultra-fine particles by grinding, in that superheated steam or technical gases is/are used as working stock, wherein at least one surface-active additive is fed to the grinding stock for stabilization of the generated ultra-fine particles. A jet mill for performing this method, having an integrated dynamic air classifier, and a grinding chamber into which superheated steam or technical gases are provided as working stock via working stock feed devices as grinding stock and in which the grinding stock is ground into ultra-fine particles by grinding, and wherein feeding devices for at least one surface-active additive for stabilization of the generated ultra-fine particles are provided.

  • Publication number: 20130196047
    Abstract: A process for the production of natural stimulants based on fat-containing masses. To produce the fat-containing mass, the raw materials are fed into an apparatus first. These raw materials are mixed in the apparatus and the required processing temperature and consistency are set. Then the mixed raw materials are liquefied in the apparatus by adding at least one fat and/or at least one oil. Finally, the fat-containing mass produced is pulverized through circulation between the apparatus and a grinding mill. The grinding mill may include two grinding zones. In the first grinding zone, the coarse components are pre-ground. In the subsequent main grinding zone, the pre-ground components are pulverized.
