Title: Script preprocessing system and method
Inventor: LYONS KENNETH BRENT
IPC: G06F17/30
Filed: 1995-10-19
Granted: 2000-05-16
Abstract: A preprocessing script-based data communications system and method that embeds information regarding the previous state of the system within script data. This effectively imposes a state memory upon what would otherwise be a stateless system. Typically, the scripts processed by this system are similar in structure and format to ordinary HTML scripts, with the addition of several commands that facilitate programming embedded state information. Within systems employing the invention a client is afforded the capability of having one script influence another by exploiting the preprocessor imposed state memory. In addition, the invention provides these advantages to a client without the need for storing state information on a data system server, thereby providing increased system security.

Abstract: A novel tie-back assembly is provided for erecting a retaining wall assembly having a plurality of face plates which  interlock  with  tie-backs.  The  tie-back  assembly includes a plurality of elongated metallic rods which are arranged in spaced, substantially-parallel fashion.   A key member is operatively securely associated with forward ends of the rods, e.g., by being a key block member which is formed of a suitable casting material, which is cast at one end of the rods and which encloses a portion of the forward ends of the rods.  At least one anchor member is arranged at a location which is spaced from the key member and which is operatively securely associated with each rod, e.g., by being an anchor block member which is formed of a suitable casting material, which is cast at a location which is spaced from the key block member and which encases a portion of each rod.  The anchor member, e.g., the anchor block member, has an elongated body extending transverse to the longitudinal axis of the rods and is of a length which is greater than the separation distance of the rods.  This structure stabilizes the tie-back assembly against twisting when arranged in a completed retainer wall assembly.

Title: Apparatus and method for focus control
Inventor: CESHKOVSKY LUDWIG
IPC: G11B7/125
Filed: 1996-12-05
Granted: 2002-02-12
Abstract: Control apparatus and method are disclosed for shifting focus on a multilayered optical medium using closed loop servo operation. The outputs of an astigmatic optical pickup are independently modified by a control sign al generator according to a predetermined time varying pattern to produce a deceptive error signal that changes the apparent focal offset seen by a serv o circuit. While in closed loop mode, the servo tracks the shifting apparent focal plane from a first information layer of the medium toward a second information layer. Thereafter the control signals are removed, and the servo locks focus on the second information region.

Patent CA-2196758-C (CA)
Inventor: MOESSNER RICHARD CROSBY
IPC: G05D23/19
Filed: 1995-07-21
Granted: 2006-02-28
Abstract: A preferred temperature control strategy was devised to remove heat from the analyzer and control the optical bench temperature continuously at aim. A foil-type RTD temperature detector is fastened to the optical bench to serve as a measurement input device for a PID control strategy, which is truly aim-seeking. The control strategy employs a heat pipe technology to remove heat from the analyzer enclosure. A heat pipe utilizes a fluid (such as an alcohol) to remove heat by evaporation of the fluid at an internal air circulation heat exchanger and then recondensing the fluid at an external air circulation heat exchanger. The PID temperature controller achieves the desired temperature setpoint by manipulation of heat exchanger fan speeds. The heat removal rate can be very precisely controlled. In practice, both heat exchanger fans could be controlled together, however, to achieve optimal internal temperature uniformity, the internal heat exchanger fan is maintained at full speed and just the external fan is controlled to adjust heat removal rate. Optical bench temperature control is maintained to plus or minus 0.1 degree C vs. a typical temperature control band of plus or minus 2 degrees C.

Abstract: This invention relates to an environmental coupling that reduces spillage to less than 1 ml. One ball valve (22') includes flat surfaces (102') on the ball and a retainer (104') with "flats" (106') that correspond  to the "flats" on the ball valve. This feature keeps the ball valve (22') on centerline and allows valve actuation without damage to either ball valve. The coupling also provides other numerous safeguards against spillage. For instance, the handle design prohibits wrong sequencing of opening and closing the ball valves.

Abstract: A fan end bracket for a motorized fan assembly has a plurality of curvilinear tapered air passages. Each air passage includes a flow port, such that air being moved by a rotating fan assembly is directed through the air passages and the flow ports. A skeletal motor assembly is affixed to one side of the end bracket such that the motor shaft is disposed through a shaft aperture in the end bracket. A rotating fan member is affixed to the motor shaft adjacent to the other side of the end bracket. A  shroud member is provided to shroud the rotating fan member so as to cause the flow of air to be directed through the air passages. A baffle plate is interposed between the rotating fan member and the end bracket. The baffle plate includes a plurality of curvilinear scallops which correspond to the air passages in the end bracket. An effective flow port is created between the scallops of the baffle plate and the tapered ramp surfaces of the end brackets so the size of the effective flow port may be adjusted by merely changing the baffle plate so as to optimize the flow and pressure parameters of the fan for a particular motor size.
