 Readhering and removable adhesive - US Patent 4684685   (Site not responding. Last check: 2007-10-10)
The preferred formulation for the gelled adhesive of the present invention is composed of: (A) an elastomeric (rubber) component, (B) a friction reducing agent, (C) a tackifier, (D) an antioxidant and, (E) a gelling agent.
Applicant has determined that friction reducing agent is advisably included in the formulation, since the combination of natural rubber latex and tackifying agent by itself does not have quite the optimum degree of coatability that is required for consumer application of the gelled adhesive produce.
A preferred class of gelling agent for use in the context of the present formulation has been determined to be a salt of an aliphatic carboxylic acid wherein the cation consists of an alkali metal.

 Marmalade - Wikipedia, the free encyclopedia
Marmalade (Media:marmalade.ogg) is a sweet conserve made from fruit, sugar, and (usually) a gelling agent.
The extension of "marmalade" in the English language to refer to citrus fruits was made in the 17th century, when citrus first began to be plentiful enough in England for the usage to become common.
In some languages of continental Europe a word sharing a root with "marmalade" refers to all gelled fruit conserves, and those derived from citrus fruits merit no special word of their own.

 Pie mixes   (Site not responding. Last check: 2007-10-10)
Under normal commercial conditions it is not possible to give the filling a sufficiently long boil to sterilise the gelling agent and particularly the spices because there are usually problems with the mixture sticking to the kettle and also a large loss of aroma.
For this reason it is advisable to use a sterile gelling agent and also sterile spices either of the Oleo Resin, spread on salt kind (Saromex from Bush Boake Allen) or else natural spices sterilised with Ethyl Oxide.
The gelling agent should be sterile, should give an attractive sheen to the filling when cold and should have good freeze-thaw stability to prevent syneresis or break-down of the starch during cooling and distribution of the pie.

 Explosive composition with tellurite gelling agent - Patent Review 4032376
In accordance with the present invention this gelling is achieved by having a gelling agent which forms cross links and thus gels as the cross links form and an agent which promotes the formation of such cross links and the consequent gelling.
By controlling the ratio of the amounts of gelling agent and the promoter the rate of gellation can be controlled so that gellation can occur practically instantaneously or at a predetermined time during a period extending, if desired, to several days.
Tellurites have the property of promoting the rate of formation of cross links between the molecules of the gelling agent thus increasing the rate of gellation, and the rate of gellation can be increased or decreased by increasing or decreasing the ratio of the amount of the tellurite to the amount of gelling agent.

Water gelling agents viscosify fresh water and light salt brines enhancing the frac fluids proppant transport properties.
Selection of the proper gelling agent is dependent on downhole conditions and formation characteristics.
Metallic cross-linkers connect the polymer chains and greatly increase the apparent viscosity of a gelled fluid, which increases the proppant carrying efficiency, allowing for higher proppant concentrations to increase the fracture width.

Care must be taken to not retard the gel by pouring the Gelling Agent when there is still too much ammonia in the mix.
When it is eventually time to pour the Gelling Agent, the observant user can see that the Gelling Agent causes a lighter color in the foam.
We know this is not as effective as a color tracer in the Gelling Agent, but the conscientious user should be thorough with the gel mixing, irrespective of color.
