1. A printhead and ink supply arrangement suitable for utilization in a print on demand camera system comprises
a housing;
a baffle unit encased in the housing and, together with the housing, defining a number of ink storage chambers, the baffle unit being configured to inhibit ink acceleration as a result of movement of the camera system;
an ink distribution manifold arranged on the baffle unit and defining a series of slots, the series being in fluid communication with respective storage chambers and ink outlets; and
a printhead arranged on the ink distribution manifold to receive ink via the ink outlets.
2. A printhead and ink supply arrangement as claimed in claim 1, in which the housing and the baffle unit define three ink storage chambers for inks of different colors.
3. A printhead and ink supply arrangement as claimed in claim 1, in which the printhead is in the form of a printhead integrated circuit.
4. A printhead and ink supply arrangement as claimed in claim 3, in which the manifold defines a printhead aperture, the printhead integrated circuit being secured in the aperture with a suitable adhesive.
5. A printhead and ink supply arrangement as claimed in claim 4, in which the printhead integrated circuit is of an elongate structure and is attached to the ink distribution manifold by means of silicone gel or a like resilient adhesive.
6. A printhead and ink supply arrangement as claimed in claim 5, in which the adhesive is applied only to interconnecting faces of the aperture and printhead integrated circuit so that a risk of blocking ink supply passages formed in the printhead integrated circuit is minimised.
7. A printhead and ink supply arrangement as claimed in claim 1, in which the baffle unit includes a number of spaced apart baffles formed to reduce acceleration of the ink in the storage chambers.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A waterproofing membrane composition which is strong, workable and easy to apply, flexible, passes ASTM D4068, and cures quickly allowing for flood testing after 24 hours at 70\xb0 F., comprising: a flexible epoxy resin; a flexible curing agent; an acrylate functional urethane resin epoxy flexibilizer; sand or other inert filler; and an effective amount of a poly(p-phenylene terephthalamide) polymer fiber andor poly(m-phenylene isophthalamide) polymer fiber.
2. The composition of claim 1 wherein the composition further contains an epoxy reactive diluent.
3. The composition of claim 2 wherein the polymer fiber is poly(p-phenylene terephthalamide).
4. The composition of claim 2 wherein the epoxy reactive diluent is an aliphatic glycidyl ether.
5. The composition of claim 1, wherein the polymer fiber is poly(p-phenylene terephthalamide).
6. The composition of claim 5 wherein the polymer fiber is fibrillated.
7. A method of applying a waterproofing composition to a substrate comprising: providing a substrate to be waterproofed; applying a waterproofing membrane composition to the substrate surface; and curing the composition; wherein the waterproofing membrane composition comprises: a flexible epoxy resin; a flexible curing agent; an acrylate functional urethane resin epoxy flexibilizer; sand or other inert filler; and an effective amount of a poly(p-phenylene terephthalamide) polymer fiber andor poly(m-phenylene isophthalamide) polymer fiber.
8. The method of claim 7 wherein the composition further contains an epoxy reactive diluent.
9. The method of claim 8 wherein the epoxy reactive diluent is an aliphatic glycidyl ether.
10. The method of claim 7, wherein the polymer fiber of the composition is poly(m-phenylene isophthalamide).
11. The method of claim 10 wherein the polymer fiber is fibrillated.
