Title: Tooling method and apparatus for resin transfer molding
Inventor: LEONI PETER B
IPC: B29C45/14
Filed: 1991-10-23
Abstract: ABSTRACT OF THE DISCLOSURE                  Tooling Method and Apparatus for Resin Transfer Molding An apparatus and method for resin transfer molding composite articles of complex configuration that have high fiber-to-resin ratios.  The molding apparatus includes a compliant mold subassembly comprising one or more conformable cauls and a complementary, non-permeable membrane that function, in combination, as a semi-rigid molding tool.  The compliant mold subassembly is relatively insensitive to bulk variations of layed-up fiber reinforcement material, facilitating fiber reinforcement material lay up and closure of the molding apparatus.  The compliant  mold  subassembly  provides  uniform pressures during various molding stages, i.e., resin injection, expulsion of excess resin, curing, to enhance the homogeneity and dimensional stability of the finished composite article.   The semi-rigid aspect of the compliant mold subassembly facilitates demolding of the finished composite article.  The process utilizes staged pressurization transmitted through the compliant mold subassembly to enhance resin flow for complete, uniform saturation of fiber reinforcement layups and to expel excess resin prior to  curing  of  the  resin-impregnated  fiber reinforcement layups.

Title: Enhanced operation toilet
Inventor: HENNESSY ARNOLD
IPC: E03D5/00
Filed: 1992-06-29
Abstract: ENHANCED OPERATION TOILET               ABSTRACT OF THE DISCLOSURE         A water saver toilet is provided, of the type that applies  a  vacuum to the  toilet bowl  outlet  to  assist flushing, which effectively uses the vacuum and which can be of low height.  The toilet bowl outlet includes upper and lower trap devices (44, 50 in Fig. 2) connected by a trapway (46),   with  the  lower  trap  device  being   initially unobstructed.   At the beginning of flushing, the initial water flow causes obstruction of the lower trap device to air flow, and a vacuum is then applied to the trapway to pull out water and debris from the toilet bowl.  One vacuum source (Fig. 3) includes a diaphragm device (76) which separates a water chamber (82) from a vacuum chamber (80).  The water chamber is initially filled with water, which is rapidly emptied during flushing,  causing the diaphragm device to rapidly fall and produce a vacuum in the vacuum chamber that is connected to the trapway.  A biasing device (84) allows the  water  chamber  to  deliver  water  at  a  considerable pressure, regardless of the level of the water chamber with respect to the toilet bowl.  Another vacuum source (Fig. 7) includes a water powered actuator (158) that receives water from a pressured water pipe at the beginning of flushing, to rapidly raise a vacuum diaphragm (170) that produces a vacuum in a vacuum chamber (172) which is connected to the trapway.
