Title: Method and dispenser for making dental products
Inventor: TATEOSIAN LOUIS H
IPC: A61K6/893
Filed: 1994-06-22
Abstract: A method of forming dental products, such as dentures, denture relines, dental crowns, dental bridges and dental restorative materials, temporary crown, temporary bridge, provisional crown or provisional bridge, from two polymerizable paste compositions each having a complimentary component of a free radical catalyst system and a polymerizable acrylic compound. One of these paste compositions includes an oxidizing agent and a stabilizer and the other includes a reducing agent as components of a redox catalyst system for free radical polymerization. These paste compositions are mixed in a static mixer to form a polymerizing paste composition, which is then shaped into a dental prosthesis. A handheld mixing dispenser useful in carrying out this method, includes a static mixing conduit, and two containers enclosing the polymerizable paste compositions. The static mixing conduit encloses a static mixing member. The containers are adapted to be connected in fluid flow communication with the static mixing conduit. In the paste composition which includes the reducing agent a photoinitiator may be preferably included. Each container is sufficiently oxygen permeable to maintain inhibition of polymerization of the polymerizable paste composition therein for at least 12 months at 23°C.

Title: Flow control means for filtering apparatus and the like
Inventor: KALMAN PETER G
IPC: B29C48/691
Filed: 1994-09-12
Abstract: ABSTRACT            Filtering apparatus includes two or more passages (2) acting in parallel, each having an extended filter (12) which passes through inlet and outlet ports (48, 49), flowable preferably sealed by solidified plugs of the flowable substance such as a polymer being filtered.  The flow of such substance to one passage can be terminated so as to permit filter advance under conditions of zero pressure drop, whilst flow through the other passage continues.  Filter advance can be assisted by extrusion of a sealing plug in the outlet port under the pressure of such substance from the other passage which is still filtering.  In additional or alternative mode, flow into a passage is terminated and a secondary outlet (20, 21) in that passage is opened.  This creates a counterflow under the pressure of substance from the other passage, which cleans the filter.  The secondary outlet can be sealed by a plug which is extruded during counterflow.  An alternative valve for the secondary outlet, which can also be used in a diverter valve for controlling the input of substance to the two passages, has a side passage (26) in which is formed a plug of solidified substance, and means (27) for pushing the plug into the flow substance.

Each panel has an upper stud and a lower stud joined by at least one vertical stud.  Only one vertical stud is used if the panel is to be joined, along the vertical edge that lacks a vertical stud, to another panel.  The vertical edge having a vertical stud may or may not be interconnected to another panel.  If the vertical stud is to be joined to the vertical stud of another panel, that stud must be designed for direct connection with that other panel.  One such vertical stud is "?" or "?"  shaped, carrying male connection elements for interconnection along the edge of a panel that does not have a vertical stud.  The connection elements may also be carried by the upper stud, the lower stud, or by both the upper and the lower stud.  Another such vertical stud is "?" or "?" shaped, and typically is used for perpendicular connection with a similarly shaped stud along the converging sides, i.e., the faces of the "V" portion.  The panels have empty space left between the studs to allow for later insertion of insulation material or other construction materials.
Patent CA-2138528-A1 (CA)
Title: Reusable Pharmaceutical Dispenser with Full Stroke Indicator
Inventor: HABER TERRY M
IPC: G01F11/02
Filed: 1993-06-10
Abstract: A pharmaceutical dispenser includes a housing (4), containing two pharmaceutical cartridges (32,34), slidably mounted to a sliding body (100). A replaceable needle manifold assembly (10) is mounted to the housing and fluidly couples the cartridges with a hypodermic needle at a common exit. The sliding body is part of a reciprocating drive assembly used to drive a pair of drive stems (88) against the pistons (96, 98) of the cartridges, thus forcing predetermined amounts of the pharmaceuticals out the needle. The movement of the sliding body between retracted and post-injection positions remains constant. However, the amounts and proportions of the pharmaceuticals injected during the delivery stroke is chosen by the user using stroke adjusters (182) carried by the sliding body. A bistable status flag (186) is mounted to the sliding body to indicate when the sliding body is in the post-injection and the retracted positions. The dosage adjustments are made when the sliding body is in the post-injection position. If a dose selected is more than is available, the sliding body is prevented from moving to the retracted position so that the status flag is not tripped.
