Title: Method for the electrolysis of an aqueous solution of hydrogen chloride or chloralkali
Inventor: GESTERMANN FRITZ
IPC: C25B1/00
Filed: 2004-08-31
Abstract: The invention relates to a method for the electrolysis of an aqueous solution of hydrogen chloride or chloralkali in an electrolytic cell (1) consisting at least of the following elements: an anode half-cell and an anode, a cathode half-cell and a gas-diffusion electrode as the cathode and a cation-exchange membrane for separating the anode half-cell and the cathode half-cell. According to said method, a gas containing oxygen is fed to the cathode half-cell and excess gas containing oxygen is drawn off from the cathode half-cell. The method is characterised in that the excess gas containing oxygen that is drawn off from the cathode half-cell is subjected to a catalytic oxidation of hydrogen.

Title: Refrigerant composition
Inventor: BROWN WILLIAM
IPC: C10M145/36
Filed: 2004-10-20
Abstract: This invention describes a new refrigerant/lubricant combination for use in stationary and mobile refrigeration and air conditioning applications. In these applications, the refrigerant and lubricant must be soluble in each other (e.g., miscible) to ensure adequate lubricant circulation from the compressor, through the condenser, expansion device, and evaporator, and back to the compressor. Insufficient lubricant circulation will result in compressor failure. Low temperature solubility is particularly important to ensure lubricant flow through the cold evaporator. In addition, the lubricant and refrigerant combination should be stable in the presence of steel, and aluminum and copper containing metals. This invention describes the combination of refrigerant difluoroethane (R-152a) and polar, oxygenated lubricants, particular polyalkylene glycols (PAGs) and polyolesters (POEs) which may be used as a "drop-in" replacement for R-134a.

Abstract: A motor drive circuit which can be suitably made into a small IC, has a reduced number of outer components and a small size, and is capable of stably rotating a motor. When a rotor (101) is rotated by three-phase drive signals U, V, W generated according to a CLK signal from a VCO (7), the induced voltage in the three-phase coil (102) is monitored, and the phase shift from the electrical phase of the rotor phase is detected. A charge pump circuit (5) is driven with an up signal f_up which is active for the time corresponding the phase delay when the rotor phase is lagged behind the electrical phase or with a down signal f_down which is active for the time corresponding to the phase lead when the rotor phase is ahead of the electrical phase. This motor drive circuit (1) instantaneously, dynamically, and directly varies the voltage at the VCO control terminal (T_cp) according to the detected phase shift information without using a smoothing filter. ® KIPO & WIPO 2007

IPC: H04L29/10
Filed: 2007-01-04
Abstract: An apparatus and a method for network address allocation are provided to complete IP address allocation before finishing booting an OS by implementing a DHCP(Dynamic Host Configuration Protocol) client function within a device driver. A device driver checks up whether a modem is set to use the DHCP(510). If not, the modem performs a network accessing procedure(515) and then waits for an instruction of a subscriber or an OS(Operating System). Otherwise, the modem switches into a DHCP use mode by activating the DHCP mode(520). The device driver accesses an IEEE 802.16e network(525). The modem generates interrupt indicating network access of the device driver. The device driver receives the interrupt, and offers the interrupt to a DHCP pitcher. The DHCP pitcher performs an IP address allocation procedure by driving the DHCP client function(530), so as to receive an IP address(540), and then provides the IP address to the network interface(545).
