Title: Client server communication system and method
Inventor: KUSUDA RIKA
IPC: H04L29/06
Filed: 1999-11-09
Granted: 2003-07-02
Abstract: An information terminal 110, connected to one of a cluster 140 of collaboration servers 142-146 which are allocated by a dispatcher 120, is connected to another information terminal 170-174 via its allocated server. When a customer's web-browser 111 is connected to, say, server 142 by the dispatcher, a button for requesting connection to an agent is displayed. When the customer clicks this button, a customer ID and an IP address of the server 142 are stored in a table 155. After a Computer Telephony Integration server 163 allocates an agent, an agent proxy 173 obtains the stored IP address corresponding to the customer and accesses the server 142. If a customer's own telephone number is also stored, the customer can receive a call back from the agent. The customer can choose as communication means with the agent either a normal external telephone, an internet phone, or chat, (conversational hypertext) and receives a call back by the chosen communication means. The skill group of the agent can be also selected.

Title: Wet scrubbing gas from electrolytic aluminium prodn. ovens
Inventor: PACHLEITNER PETER H
IPC: B01D/
Filed: 1982-07-16
Granted: 1987-01-28
Abstract: Arrangement is intended for wet scrubbing the gas emerging from electrolytic aluminium prodn. ovens (3) using liq., partic. water, sprayed to form a mist. The gas is passed (horizontally) through a scrubbing chamber whilst water at a pH of around 8 is sprayed in a direction at right angles to the gas flow. At a point before the clean gas outlet the gas passes through a separator to remove suspended droplets. The gas flow rate through the chamber may be up to 3 m/s, and is pref. around 1 m/s, whilst its dwelling time in the chamber may be 20-60 secs., pref. around 40 secs. Upstream of the chamber, solids may be removed from the gas, e.g. by electrical pptn. Used for wet scrubbing gas from electrolytic Al prodn. ovens before discharge into atmos. The process effectively removes fluoride whilst at the same time removing 70-90% of SO2 which is not achievable with the conventional dry adsorption methods.

Title: Ice block making appts.
Inventor: SPINNEY PETER MICHAEL
IPC: F25C/
Filed: 1980-04-22
Granted: 1986-05-28
Abstract: The appts. comprises an ice block mould having a casing connected into a heat transfer fluid circuit having a heat exchanger for chilling the heat transfer fluid by means of a refrigeration circuit. The heat transfer circuit has a pump for pumping the fluid from the heat exchanger through the mould casing, a cold balance tank on the low pressure upstream side of the pump and a warm balance tank for heating cold heat transfer fluid. During operation of the pump a static head of heat transfer fluid is built up in the warm balance tank and when operation of the pump is discontinued warm heat transfer fluid passes from the warm balance tank into the mould casing to displace cold heat transfer fluid into the cold balance tank. This releases ice blocks formed in the mould by melting the surface of the block in contact with the mould. The appts. operates automatically without the need for valves, in the heat transfer circuit. The mould casing can be easily changed to provide different sized ice blocks.

Title: Friction pad guide for disc brake
Inventor: KAZUO SAITO
IPC: F16D/
Filed: 1980-09-08
Granted: 1986-06-04
Abstract: The liners (13,14) of the friction pads are bent perpendicularly at both side ends toward the back surface sides to form vertically bent portions (13a,13b,14a,14b) which are slidably engaged with inner vertical guide surfaces (9a,10a,11a,12a) extending above a torque retainer. The upper portions are bent perpendicularly toward the opposite side directions to form laterally bent portions which are slidably engaged with the inner lateral guide surfaces (9b,10b,11b,12b) of the torque retainer. This slidably suspends the friction pads from the torque retainers. The length (L) of the vertically bent portions is formed to be greater than the thickness (l) of the liners (13,14) so that damage to the guide is prevented by the increased sliding area. If the configuration is such that the guide portion ends at the disc portion, the liners are prevented from dropping from the guide when the friction pads are worn out. It becomes unnecessary to finish the side end surfaces of the disc in the guide after casting the torque retainer.
