Title: Groundwater recovery system
Inventor: BLANCHARD CHARLES EASTMAN
IPC: F04F1/20
Filed: 1994-09-13
Abstract: The specification discloses a system for recovering groundwater from a subterranean aquifer (12) through an extraction well (20) having a perforated casing (28) extending down to the water table (14) and a drop-tube (24) within the casing (22) to define an annular area (23) between the casing (22) and the drop-tube (24).

Title: Manifold medication injection apparatus and method
Inventor: PAWELKA GERHARD E F
IPC: A61M5/24
Filed: 1994-04-01
Abstract: A hand-held dual liquid medication injector (100, 400) having dual, bi-directional dosage metering mechanisms (252, 253, 410) for permitting a variable dosage amount for each cartridge (104, 106) of liquid medication. The medications are mixed within a manifold (122) having a valved mixing chamber (14) and are injected via a single cannula (121). The mixing chamber is valved (136) such that backflow of mixed or unmixed medications into the cartridges is prevented.  An injection mechanism (116, 254, 412), independent of the metering mechanism, loads and injects the liquid medication. In one embodiment, transverse movement of the injection mechanism (116) during injection is translated into horizontal movement by the plunger mechanism.  In another embodiment, a power-assisted plunger mechanism (412) accomplishes injection.

Patent CA-2166891-A1 (CA)
Title: Method for making freeze dried drug dosage forms
Inventor: WONG SANG K
IPC: A61K9/20
Filed: 1994-07-08
Abstract: The present invention discloses an improved technique for preparing a rapidly dispersing pharmaceutical tablet of a granular therapeutic agent which has both relatively low solubility and relatively large particle size. Xanthan gum is added to a liquid admixture of solvent, carrier components, and the granular therapeutic agent. The xanthan gum not only facilitates suspension of the granular therapeutic agent in the liquid admixture, but, more surprisingly, does so without adversely affecting the dispersion qualities and texture of the tablet in the patient's mouth upon administration.

Title: Urethane-free, diphenylmethane diisocyanate prepolymers and process for their production and use
Inventor: SLACK WILLIAM E
IPC: C08G18/71
Filed: 1996-04-15
Abstract: Allophanate-modified MDI which is a storage stable liquid at 25°C is produced in two steps. First, a monoisocyanate is reacted with an organic material having about 1.8 or more hydroxyl groups and a molecular weight of from about 60 to about 6,000 to form the urethane. The urethane is then reacted with an isomeric mixture of MDI in an amount such that the resultant isocyanate will have an NCO content of from about 3 to about 28%. The isomeric mixture of diphenylmethane diisocyanate contains from about 0 to about 60% by weight 2,4'- diphenylmethane diisocyanate, less than 6% by weight 2,2'-MDI and the remainder 4,4'-MDI. The prepolymers of this invention are particularly useful in reaction injection molding processes because molded articles having improved flex modulus are obtained.
