Title: Foam dispensing system for a foamable liquid
Inventor: LUND MARK T
IPC: B05B11/00
Filed: 1994-11-14
Granted: 1999-12-28
Abstract: A foam dispensing system for a foamable liquid has a means for producing a spray of droplets in which the spray of droplets has key parameters of: the number averaged mean diameter and the mean axial droplet velocity.    The foam dispensing system also has a foaming nozzle connected to the means for producing a spray of droplets that is placed in fluid communication with the spray,of droplets. The foaming nozzle has a screen which has a plurality of screen openings having a U.S. Sieve Series mesh range from 30 to 60 mesh.   Key parameters of the screen are: the percent open area is from about 35% to 60%, and the screen openings are larger than the number average mean diameter of the spray of droplets. When the mean axial droplet velocity is at least 8 m/s, the spray of droplets is transformed into a foamed spray as the droplets pass through the plurality of screen openings.

Title: Unitary suspension clip for supporting partition panels
Inventor: AGAR ROBERT S
IPC: E04B2/74
Filed: 1994-12-07
Granted: 1998-08-11
Abstract: A unitary suspension clip for suspending gypsum board panels from the horizontal channel member of an erect support structure.   The plate portion of the clip has panel-piercing members projecting rearwardly to affix the plate to the panel.  A transverse line of weakness extends substantially across the width of the plate such that when the panel is suspended from the channel member, the load applied between the channel member and the plate causes the plate to bend therealong to prevent the pulling of the panel-piercing members out of the panel.  A wing is formed along the edge of the plate and extends outwardly therefrom with  a  second  line  of  weakness  running  in  the  same direction as the edge of the plate between the wing and the plate.  The wing is bent at the second line of weakness upwardly from the surface of the gypsum board panel and has an  angled  surface  formed  therein  which  rests  on  the horizontal channel member and causes the panel to be drawn into engagement with the erect support structure.

Granted: 1999-09-28
Abstract: A method and system for updating a replicated database  of  a  telecommunications  network  system  is disclosed.  The database in a network system improves cost, setup time and system availability.  A call transport system has switches for forwarding calls from a local telephone station through the call transport system to a destination. A signaling system is operatively connected to the call transport  system and includes a primary site databases within the signaling system containing customer records for call routing and other signaling functions and at least one secondary site database containing the customer records of the primary site database.  Both primary and secondary site database maintain multiple versions of the same customer record so that queries of a call can use a version number to access the corresponding version of the record in the same database  for  consistent  routing  and  other  signaling information. A customer record is updated in the primary site database and then information concerning the updated database record is transmitted through the signaling network to the secondary site database containing the replicated version of  the  record.   The  records  are  then updated according to the sequence of the version number.   The processing of all calls querying the previous version of the primary and secondary site database record are completed before  the previous version of  the database  record is deleted.

Abstract: A method and apparatuses for cleaning a cylinder surface. The method is particularly suitable for use on flexographic printing cylinders where the automated cleaning facilitates the cleaning of plate cylinders. However, the method may be applied to any type of cylinder. The advantage is that in many cases it will not be necessary to ha lt the printing process for cleaning the cylinder. The method comprises detachment of particles such as dust, fibers and other foreign objects deposited on the cylinder surface. After the particles have become detached by means of pressurized air, liquid, ultrasound or other suitable media, the cylinder surface is exposed to a vacuum whereby the detached particles and other material deriving from the cleaning medium are sucked off the surface.

The base station further comprises a high-frequency section that carries out radio communication with mobile stations, and a base station main control unit that collectively controls processing to be conducted in the base station, thereby collectively executing the processing involved in a radio communication with the mobile stations.          The base station controller on the other hand collectively performs line communication processing.  By distributing necessary functions in this manner, the number of times communication between the base station and the base station controller is carried out is minimized.  Thus, a base station system suitable for microcells is provided.

Title: Process for applying low-cement castable refractory material
Inventor: ALLISON ERIC L
IPC: B05D1/02
Filed: 1995-07-07
Granted: 2001-01-16
Abstract: A method for placing a thixotropic low-cement castable refractory material without the necessity for forms. A low-cement castable material is mixed with a measured amount of water, then is pumped hydraulically through a hose (13) to a nozzle assembly (14). Compressed air and a cement setting agent are added to the mixture at the nozzle (14). The addition of the setting agent at the nozzle (14) overcomes the thixotropic nature of the low-cement castable, so that it will immediately "set" in position when sprayed onto a surface, including vertical and overhead surfaces.
