Abstract:
A spin coater that can be used to apply multiple coating compositions over an optical substrate, is described. The spin coater includes, a coater bowl configured to collect excess coating material expelled from an optical substrate being coated, a rotatable chuck configured to receive and rotate the optical substrate in the bowl during coating, a plurality of coating reservoirs, each containing a coating material, and an indexable coating reservoir platform containing the plurality of reservoirs and configured to index a selected reservoir into a dispensing position above the coater bowl. The spin coater can include or have associated therewith at least one curing station, in which each curing station is independently configured to cure at least partially at least one applied coating material. Each curing station can include at least one of, a thermal curing station, a UV curing station, and/or an IR curing station.

Abstract:
Apparatus (101) for producing material by a chemical reaction between a first chemical reagent and a second chemical reagent. The apparatus comprises a chemical mixing arrangement; a dispensing chamber (317); a dispensing piston (312) configured to dispense reacting mixture from said dispensing chamber; and a control means (501) for controlling the movement of said dispensing piston and for controlling operation of the chemical mixing arrangement. The chemical mixing arrangement has a mixing chamber (305) and injection means (306) configured to produce a jet of a first chemical reagent and a jet of a second chemical reagent such that said jets collide within said mixing chamber to produce reacting mixture. The dispensing chamber (317) has an inlet for receiving the reacting mixture from the mixing chamber and an outlet (319) for dispensing the reacting mixture. The control means (501) is arranged to co-ordinate movement of the dispensing piston with the operation of the chemical mixing arrangement such that the chemical mixing arrangement is caused to mix the chemical reagents while the dispensing piston is caused to move at a controlled rate.
Abstract:
A two-component resin or adhesive dispensing system (10) including an air drive motor (44) with adjustable settings which drives, by means of sprocket (54) and chain drive (62) systems, an activator metering pump (18) and an adhesive metering pump (20) as to provide a dispenser (12) with adjustable amounts of activator material and adhesive material. The metering pumps are mounted upon adjustably movable mounting brackets (46,48,50) such that their relative disposition may be readily altered so as to accommodate different sized sprocket members (54) which will then alter the drive output of the metering pumps in order to change the ratio of activator material dispensed with respect to the amount of resin or adhesive material dispensed.
Abstract:
The invention relates to a machine for filling the edge joints of insulating glass panes with a semiliquid to paste-like sealing compound. Said sealing compound consists of a main constituent and a secondary constituent which are different in chemical terms and in terms of their viscosity. According to the invention, the edge joints are filled with the sealing compound by means of two pumps (3, 6) which convey the two constituents from two reservoirs (1, 2) into separate intermediate storage parts (5, 8) and by means of separate, synchronously driven volumetric feed metering pumps (14, 19). Said metering pumps (14, 19) pump the constituents in a predetermined composition into a mixer (16) and then on to a nozzle (17). The nozzle (17) and the mixer (16) belong to one sub-assembly which is mounted as a whole on a frame of the machine in such a way that it can move. A gear pump (14) driven by a servomotor serves as a metering pump for the main constituent together with a piston pump (19) which serves as a metering pump for the secondary constituent. The piston (20) of said piston pump (19) is driven by a second servomotor (23) and the two metering pumps are preferably part of the mobile sub-assembly.
