Granted: 1995-09-26
Abstract: The method of determining kinematic parameters, allows robot wrist to orient arbitrarily without regard to the position of robot arm when attaching robot wrist with three joints having offset. The method involves determining the torsion angle(alpha4) first with regard to torsion angles(alpha4, 5) between rotational axes of three articulations constituting the robot wrist; magnitude of the torsion angle(alpha5) is determined to be equal to torsion angle(alpha4"). The robot wrist having an offset link can take arbitrary posture at any position, only when torsion angles(alpha4, 5) are decided by some calculation formulas.

Granted: 1996-10-23
Abstract: A multinode, multicast communications network has a distributed control for the creation, administration and operational mode selection operative in each of the nodes of the network. Each node is provided with a Set Manager for controlling either creation of, administration or access to a set of users to whom a multicast is to be directed. The Set Manager maintains a record of the local membership of all users associated with the node in which the Set Manager resides. A given Set Manager for each designated set of users is assigned the task of being the Set Leader to maintain membership information about the entire set of users in the multicast group. One of the Set Managers in the communications network is designated to be the Registrar which maintains a list of all the Set Leaders in the network. The Registrar insures that there is one and only one Set Leader for each set of users, answers inquiries about the membership of the sets and directs inquiries to appropriate Set Leaders if necessary. All of the set creation, administration and control functions can therefore be carried out by any node of the system and provision is made to assume the function at a new node when failure or partition in the network occurs. <IMAGE>

Title: Device for determining flow direction of underground waters
Inventor: GIURMA CATRINEL RALUCA
IPC: G01V9/02
Filed: 2003-10-13
Abstract: The invention relates to a device for determining the sense and direction of flow for the underground waters, which is used especially for managing waters in the geological field or in the hydrological constructions or hydrotechnical constructions. According to the invention, the device comprises a portable apparatus (1) for drillings and piezometers, for measuring the underground water level, mounted above a drilling (2) wherein there are provided two terminals (M and S) in connection with the underground water and with a measuring probe (3), respectively, coated with an insulator (4) made of plastics, whereto there is connected a portable apparatus (C), for measuring conductivity, and for the sound signalling for the moment when the marking substance reaches the measuring probe (3), there is mounted an amplifier (A) coupled to the input circuit to the same terminals (M and S), that determines the connection to a piezo siren (SP) at a certain value of the water conductivity.

Abstract: The invention relates to a polymer alloy meant to manufacture soles specific for the protection footwear and to a process for preparing the same. According to the invention, the polymer alloy comprises polyvinyl chloride with a 100% plasticizer absorption, vulcanized nitrile rubber, recovered from waste elastomers with a particle size ranging from 10 nium to 1 mm, said plasticizer consisting of dioctylphthalate, benzoyl peroxide as initiating agent, calcium stereate as polyvinyl chloride stabilzer, orthothiodipropionate dilauryl as antioxidant, and methyl methacrylate as compatibilizer. The process for preparing the polymer alloy consists in mixing waste elastomers from nitrile rubber, vulcanized with benzoyl peroxide as initiator and methyl methacrylate for 4 ... 5 min in an internal mixer, in adding polyvinyl chloride and dioctyl phthalate by mixing continuously for 2 ... 3 min, afterwards adding calcium stereate and dilauryl orthopropionate, mixing for 2 min, after 8 ... 10 min, the resulting mixture being discharged and passed into an extruder granulator, from the extruder there resulting cylindrical granules having a size of 2 ... 3 mm, which are processed by injection moulding with moulds having the shape recquired for utilization.
