Title: Wall for the booth of a coating plant
Inventor: KIMMERLE WALTER
IPC: B05B16/40
Filed: 1998-07-20
Abstract: The present invention relates to a wall for the cabin of a varnishing line, wherein said wall comprises in a traditional way different wall members (1, 2). Each wall member (1, 2) comprises a support frame (3) formed by vertical stands (4, 5) and horizontal crossbars (6, 7, 8, 9) made from profiled members of sheet metal. The panels are attached using the stands (4, 5) and the crossbars (6, 7, 8, 9) and are covered with plates (10, 11, 12). The vertical stands (4, 5) at least include a profiled member having a rectangular basic geometrical shape. However, two of the legs (15, 16) of the profiled member, i.e. the external leg extending vertically relative to the associated plate (11) and the outer leg (16) which is parallel to said plate (11) respectively, do not extend on the entire length on the corresponding side of the rectangle.  The inside of the stands (4, 5) can thus be accessed and mounting members can then be placed thereon. At least one chamfered area (40) is formed on the shortened leg (16) which is parallel to the plate (11), wherein said area (40) also extends up to the corresponding plate (11). The chamfered area (40) provides mechanical rigidity to the corresponding stand (4, 5) and is also used for fixing a cap (18) which is inserted between the shortened legs (16), which are parallel to the plates (11), of adjacent stands (4, 5).The cap thus provide a flushing cover of the access opening leading into the inner spaces of the two adjacent stands (4, 5).

Title: Method and apparatus for providing a pulsed water massage
Inventor: MORELAND GERALD W
IPC: A61H23/00
Filed: 1998-03-12
Abstract: A pulsing valve (10) for routing water flow from an inlet line (12) to outlet lines (14) connected to water jets (24) arranged in an array (26) to massage an occupant of a whirlpool spa or bathtub (28) is provided.      The pulsing valve (10) includes a water turbine (38) driving a selector disk (62) through a reduction gear drive (50). The selector disk contains openings (64) which oppose individual water outlet lines (14) and direct water flow to them. Rotation of the selector disk (62) switches or cycles pressurized water flow (43) among the individual outlet water lines (14), causing the massaging water jet location to move, improving the quality of the resulting massage. The speed of the cycling of the water can be changed by changing the pressure of the water delivered to the water turbine (38). Additionally, the water turbine (38) can be powered by tap water (140) instead of pressurized water and the valve can be used to cycle tap water to the individual jets instead of cycling pressurized water (43).

Patent CA-2289357-A1 (CA)
Inventor: CRICK WILLIAM R
IPC: H03K19/003
Filed: 1999-11-10
Abstract: A signal transmitter for transmitting digital logic signals and a complementary receiver, are disclosed. The signal transmitter comprises a plurality of signal drivers and at least one reference driver. The signal drivers transmit digital signals, while the reference driver transmits a constant signal representative of a digital HI or LO. The signal and reference drivers are interconnected so that any noise due to package and power supply interconnection impedances is present in all transmitted signals including any reference signals. At a receiver, the reference signal including noise is used to establish threshold levels for digital HI and LO signals.      Because noise is common to all transmitted signals, the receiver is able to reduce the effects of the noise by comparing the plurality of received signals with the reference signal.

Title: A cooling air supply system for a rotor
Inventor: ICHIRYU TAKU
IPC: F01D5/08
Filed: 2000-08-22
Abstract: In a cooling air supply system for a rotor, cooling air is supplied from cooling air nozzles to an annular cooling air passage formed around the rotor shaft. The cooling air nozzles are formed as straight air passages having circular cross sections. The straight air passages disposed on a stationary annular nozzle member surrounding the rotor shaft. Since the nozzles are formed as straight air passages having circular cross sections, the nozzles can be manufactured accurately at low cost by machining the annular nozzle member.      Further, since the freedom for the arrangement of the nozzles increases by using the straight air passages, the nozzles can be arranged in such a manner that cooling air leaving the nozzle flows into the cooling air passage around the rotor shaft without changing its flow direction. Thus, the pressure drop in the cooling air caused by changing flow direction can be largely reduced.
