Abstract: A method of controlling crosslinking reaction rate in a water based polymer fracturing fluid that involves using a mixture of a crosslinker, in combination with a crosslinking rate accelerator or a crosslinking rate retarder at a ratio such that the crosslinking reaction rate is controlled. This decreases the shear effects upon the polymer fracturing fluid during pumping which affects downhole stability of the fluid and decreases pumping and frictional pressures. The ratio of rate accelerator or rate retarder to crosslinker for a desired crosslinking reaction time is dependent upon pH, surface temperature, polymer concentration, salt concentrations, fluid loss additives, surfactant types and concentrations, mutual solvents and alcohol. The preferred polymer fracturing fluid is a high pH aqueous salt solution including a hydroxypropyl guar polymer. The preferred crosslinkers are transition metal chelates. The preferred crosslinking rate accelerators are polyamines.

Abstract: An improved process for restoring the hydrophilic property of stained non-image areas in a lithographic printing plate is described, which comprises treating said lithographic printing plate with a plate cleaner, wherein the improvement comprises using a plate cleaner comprising an aqueous solution containing a silicate and at least one surface active agent selected from the group consisting of cationic surface active agents and amphoteric surface active agents.
Abstract: A particulate fabric softening detergent composition comprises certain proportions of synthetic organic detergent, builder salt, bentonite (preferably a swelling Wyoming bentonite) and water insoluble soap (preferably aluminum stearate). The detergent composition preferably comprises spray dried built detergent beads with which are blended agglomerated beads of the bentonite and water insoluble soap. The combination of water insoluble soap and bentonite greatly increases the softening action of the composition when it is employed for hand washing of laundry.

Abstract: An improved multiple flashlamp array is disclosed having a plurality of low voltage type lamps fired individually and in sequence by means of a plurality of static solid switching devices capable of reliable actuation by radiant energy generated during flashing of the lamps. Initially, these switching devices have a high electrical resistance ("off position") and after being actuated by the heat and light radiation, they undergo chemical conversion to an electrically conductive state ("on position"). The switch devices are prepared in a conventional manner from a particulate mixture of silver oxide with oxidized copper metal and which further contains a particular organic polymer binder mixture. The low voltage flashlamps being fired in this manner require that the converted switch devices exhibit an electrical resistance after conversion not to exceed about 0.3 ohms.
