Patent GB-2350077-B (GB)
Title: Wafer polishing apparatus
Inventor: NUMOTO MINORU
IPC: B24B37/013
Filed: 1999-11-09
Granted: 2002-05-01
Abstract: The present invention is a wafer polishing apparatus with a device that detects the polishing end according to a change in rotation resistance of a wafer during polishing. The wafer polishing apparatus comprises a head body and a carrier which are connected with each other by a connecting bar which is provided with a strain gage, and determines strain in a horizontal direction of the connecting bar by the strain gage so as to determine a rotation torque of the carrier, whereby accurately detects the polishing end. Since a retainer ring is mounted to the outer periphery of the carrier via an O ring, the impact at contacting of the wafer with the retainer ring can be absorbed by the O ring, thus the wafer is prevented from damage. Because the retainer ring is mounted to the carrier without a gap, the outer periphery of the wafer is enclosed by the retainer ring, and the wafer can be polished in a state where its center is held on the central axis of the carrier. Therefore, the polishing precision of the wafer can be improved.

Title: Method and apparatus for cleaning metal workpieces
Inventor: WITTE ALEXANDER
IPC: B08B3/10
Filed: 1992-11-20
Abstract: A method and an apparatus for treating workpieces with a fluid, in particular for cleaning metallic workpieces prior to a subsequent heat treatment are disclosed. The workpieces are positioned in an air-tight washing vessel. The vessel is filled with an immersion bath substantially covering the workpieces and having a temperature of between 50 DEG  C. and 90 DEG  C. After closing the washing vessel it is evacuated down to a vacuum having a pressure being below the saturation vapor pressure of the fluid at the prevailing temperature. Thus, the fluid starts to boil although its temperature is substantially below the boiling temperature of the fluid at atmospheric pressure. After a certain period of time of maintaining the vacuum and the boiling, the vacuum is relieved and the bath is discharged.

Title: Drying of propane for use in dewaxing
Inventor: BUSHNELL JAMER DYCKMAN
IPC: B01D/
Filed: 1988-02-15
Granted: 1990-02-22
Abstract: Prodn. of dry propane for use in low-temp. dewaxing operations is effected by fractionating wet propane from the deasphalted oil recovery unit of a propane deasphalter. The wet propane has a water content of up to 2000 ppm (molar), a pressure above that in the fractionator, and a temp. of 100-140 deg. The entire heat required to operate the fractionator is supplied by part of the hot wet propane from the deasphalter. The dry propane is recovered as a prodn. stream directly from the fractionator. More specifically, the wet propane may be in vapour or liquefied form. The fractionator is operated isothermally under conditions controlled by manipulating the overhead/feed, bottoms/feed or overhead/bottoms ratio.

Title: Automotive vehicle for public transport with a load bearing body, and oscillating fork suspension with torsion bars.
Inventor: ROMANO ARMANDO
IPC: F16F/
Filed: 1983-04-07
Granted: 1987-04-08
Abstract: This invention deals with an automotive vehicle for the public transport of persons, having a load bearing body made of modular elements, whose suspension is produced by means of oscillating forks hinged with the centre, at the anterior and posterior bridges, and to the load bearing body, along the relative lower nodes; said forks are elastically suspended through the use of torsion bars. The structure described, allows for the production of automotive vehicles with a loading plane at the most minimal level possible, thereby obtaining a centre of gravity of the loaded vehicle lower than in traditional vehicles and allowing for more rapid and easier passenger entrance and exit.
Patent IT-1201943-B (IT)
Title: Heat pump system for hot water production
Inventor: MORETTI FRANCO
IPC: F24H/
Filed: 1982-04-15
Granted: 1989-02-02
Abstract: The heat pump system includes a thermally insulated water container (1) which includes a thermostatically controlled electric water heating element. At times, when the water from the heat exchanger associated with the heat pump is insufficiently heated for domestic use and would tend to reduce the temp. of the electrically heated water to an undesirably low level, the heat pump heated water circulation is automatically restricted. The primary water circuit includes the heat pump (9) and the primary of the heat exchanger (7). The secondary water circuit (4) includes the heat exchanger secondary, a circulating pump (6) and the thermostatically controlled valve (14) with a controlled restriction by-pass (16). If the water temp. detected by the sensor (S) is below a preset level, then the valve (14) closes and the only flow in the circuit (4), i.e. through the water container (1) is the restricted amount flowing via the by-pass (16). This restricted flow is such that it cannot affect the temp. of the water in the container (1) and also the temp. in the circuit (4) will rise more rapidly to a useful level.

Buffer (II) is pref. an amino-acid, esp. glycine, or a formate or acetate, whereas complex (I) is pref. a sulphatothiocyanate or a chloro-thiocyanate. The aq. soln. is pref: 1) An 0.05 molar soln. of CrCl3, 6H2O satd. with 50 g/l H3BO3, then put in equilibrium at 80 degrees C for 1 hour with 0.075M NaSCN, with 0.16M glycine, 0.5 M KCl, and with 2 M KBr after cooling, the pH was adjusted to 3.0. The soln. provides bright Cr deposits without using the noxious Cr3O3. A wide range of current densities can be used to deposit up to 0.9 mu m/minute, and plating can be undertaken through photoresist masks.
