Title: Mold for forming precast concrete panels
Inventor: VAN DOREN DAVID A
IPC: B28B1/14
Filed: 1995-04-20
Abstract: A mold especially adapted for forming precast, waffle-shaped concrete panels employs a one-piece mold body of flexible plastic sheet material to which rigid side rails are secured by tongue and groove longitudinal joints.  The mold may be rapidly stripped and reset due to a hinge action provided by partial sides of the flexible body to which the rigid side rails are joined.  The side rails and other structural features provide a simple mold structure that may be readily and efficiently employed for on-site production of panels.  The configuration of the side rails and associated joints facilitates the replacement of a wornout mold body.

Title: Apparatus and method for monitoring endocardial signal during ablation
Inventor: NARDELLA PAUL C
IPC: A61B5/296
Filed: 1993-11-01
Abstract: An ablation catheter has an ablation electrode (12) at a distal end coupled to an ablation power source (18) through a low impedance coupling (16). The ablation electrode also functions as a sensing electrode, for monitoring the endocardial signal and preferably also tissue impedance during the ablation procedure, and is coupled to an electrode monitor through a high impedance coupling (24). A timing element (34) operates a plurality of switches (20, 26, 32) to selectively isolate, dampen, or interconnect various signal paths during plural repetitive non-overlapping ablation and quiescent intervals which alternate at a rate substantially above a Nyquist sampling rate. RF energy is delivered to the ablation site during the ablation intervals. The local endocardial signal is measured during the quiescent intervals.

Title: Building or blocking component
Inventor: POWELL JAMES ANTHONY
IPC: E02D17/20
Filed: 1993-11-19
Abstract: It will be appreciated that the components may take forms other than those specifically mentioned and that use may be made of any form of scrap tyre (4). The blocking process is very simple and the preferred method is the breaking down of a tyre (4) into three portions i.e. two side walls (6, 8), one tyre tread (10). By filling the void in a larger tyre (4) by utilising smaller tyres (16) you have in effect a solid component weighing in the region 125 kg. There must come a time when a scrap tyre will have a commercial use and therefore a value.

Title: HVAC Distribution System Identification
Inventor: AHMED OSMAN
IPC: F24F11/00
Filed: 1995-10-03
Abstract: A controller implemented in a heating, ventilation and air-conditioning (HVAC) distribution system provides improved control by implementing a general regression neural network to generate a control signal based on identified characteristics of components utilized within the HVAC system. The general regression neural network utilizes past characteristics and desired (calculated) characteristics to generate an output control signal. The general regression neural network is implemented in a feedforward process, which is combined with a feedback process to generate an improved control signal to control components within the HVAC distribution system. Implementation of the general regression neural network is simple and accurate, requires no input from an operator supervising the controller, and provides adaptive, real-time control of components within the HVAC distribution system.
