Title: Adjustable bar screen
Inventor: BIELAGUS JOSEPH B
IPC: B07B1/16
Filed: 1994-08-22
Granted: 1998-10-13
Abstract: The bars of one of two sets of interleaved screen bars is extended beyond the interleaved portion of the screen bed, thus forming a region of the screen bed which has screens particles of intermediate dimensions. A second improvement is a clamping member which holds the downwardly extending legs of individual bars of the screen. The clamping member is a steel channel which has a steeply peaked roof between legs which sheds particles. The bar legs fit into slots which penetrate the peaked roof transverse to the lengthwise direction of the channel . The legs are retained by transverse bolts which pass through the vertical sidewalls of the channel and the legs, retaining and clamping them. The third improvement mounts the clamping member to a flange which may be traversed by a screw and bolt arrangement such that the clamping member may be adjusted in its lateral position. A fourth improvement is a clamping member which extends longitudinally and which has a keyway formed therein. Bars with downwardly downwardly legs extend transversely to the direction of the clamping member. The legs have transverse keys which fit into the keyway formed in the clamping member.

Title: Combination inner plate and outer envelope electrodes
Inventor: TOMBA CHARLES P
IPC: C25B11/02
Filed: 1995-09-08
Granted: 2000-04-25
Abstract: Electrodes in plate form can be electrocatalytically coated and secured to a current distributor, such as by welding to a base plate, and may be serviceable, e.g., as anodes, in cells electrolyzing brine.  Recoating of plate electrodes can require removal from the cell, removal of old coating, application of fresh coating, then returning and securing the freshly coated electrodes to the cell. There are now provided envelopes for covering the original electrode plates.  The original plates thus do not need to be separated from a base member of the cell. The envelopes can have an electrocatalytic coating on their outer surfaces.  The resulting electrodes are thus a combination of an old inner plate and a new outer envelope, with an outer surface coating on the envelope. The envelopes can be secured to the inner plate and/or to a current distributor such as a base plate.

Title: Standby operation in a wireless communication device
Inventor: MOORE DOUGLAS CRAIG
IPC: H04M1/72448
Filed: 1995-11-15
Granted: 2002-01-01
Abstract: A wireless communication device (106, 108) incorporates a convenient method for storing/enabling preferred functions which are activated when the communication device is in a standby mode. Recent products and systems adapted to operate with cellular systems have enhanced the functionality of a wireless communication device when a user is not present. For example, the transmission of cellular digital messages, paging messages and facsimiles or computer files by way of cellular networks can be accomplished when a cellular telephone is unattended. The present invention eliminates the need for a user to enable a standby mode before a communication device (404) is left unattended. Further, the present invention provides preferred functions to be enabled (306) when the communication device in the standby mode. If the standby mode is selected (406), the communication device will automatically perform preferred standby functions (414) after the device is unattended.

The   phosphorescent   synthetic   resin   material   having  a phosphorescent  pigment,  SrAl2O4, uniformly  dispersed  in  the synthetic resin is obtained by mixing the synthetic resin with the phosphorescent pigment and an activator and kneading the resultant mixture at a temperature 10 to 20 °C  higher than the melting  point  of  the  synthetic  resin.     In  a  preferred embodiment, the resultant compound is extruded at a temperature to  20°C  higher  than  the melting point  of  the  synthetic resin under an extrusion pressure in the range of 50 to 130 kg/cm2  and  the  extruded  strands  are  chopped  to  produce pellets.    By  injection  molding  or  extrusion  molding  the produced pellets into a desired shape,  the formed article of synthetic   resin    possessing    outstanding    phosphorescent properties is obtained.

Title: Method for voc abatement and paint spray booth incorporating such method
Inventor: GRIME THOMAS E
IPC: B05B15/12
Filed: 1996-06-24
Granted: 2000-08-22
Abstract: A VOC (volatile organic compounds) adsorbent material such as an alumino-silicate gel desiccant is treated with a masking agent to reduce its affinity for VOC's to a level that the material can be regenerated at a predetermined low temperature which will not desorb the masking agent. The treated adsorbent material is used to adsorb VOC's and is periodically regenerated with heated air. The treated adsorbent material may be used to adsorb VOC's from recirculated spray booth air while spraying a coating on a workpiece. Subsequent to spraying, the spray booth air is heated to above the VOC regeneration temperature to regenerate the adsorbent material and optionally to cure the applied coating. As the heated spray booth air is circulated through the adsorbent material, the previously adsorbed VOC's are desorbed. The desorbed VOC's may be destroyed by oxidizing, for example, with a catalyst.

Title: Double walled insulated tubing and method of installing same
Inventor: SPRINGER JOHANN
IPC: E21B33/047
Filed: 1995-05-23
Granted: 2000-10-31
Abstract: A double walled insulated tubing string (46) adapted to be hung from a well head (58) has an inner tubing string (21) formed of plural inner tubes and a radially outer tubing string (22) formed of plural outer tubes, the strings being independent of one another apart from axially fixing the strings relative to one another at the top end of the tubing string, although axial fixation may also be provided at the lower end of the tubular strings if desired. An annular insulating gap (30) between the tubing strings (21, 22) is hermetically sealed at both opposing ends and may be evacuated. The inner and outer tubing strings may be run into a well using conventional oil well drilling technology and there is no mechanical connection between the inner and outer tubing strings (21, 22), especially at the connections of the respective inner and outer lengths of tube. To maintain the inside of the outer tubing string (22) free from formation liquids before the inner tubing string (21) is run into the well and sealed against the outer string at its lower end, a temporary plug (31) initially closes the lower end of the outer string and is de-activated before liquid can flow through the thermally insulated dual tubing string (46).
