Abstract: A crosslinker composition that can produce delayed crosslinking of an aqueous solution of a crosslinkable organic polymer. The composition comprises a metal compound, preferably an organic metal complex, and most preferably an organic zirconium complex. The composition further contains an organic hydroxycarboxylic acid, preferably hydroxyacetic acid. The pH of the composition is preferably no more than 4.8. The pH of the composition is further preferably such that when sufficient amount of composition is added to an aqueous polymer solution to result in delayed crosslinking of the polymer, the composition produces a pH in the resulting gel solution, preferably of between about 3 and about 4.5. Gel solutions produced using the composition are particularly useful in fracturing subterranean formations, and in particular in fracturing subterranean formations penetrated by an oil well in which fracturing process carbon dioxide and a proppant are added to the fracturing fluid. Aqueous organic polymer solutions which can be crosslinked by the composition, include guar, hydroxypropyl guar, carboxymethylhydroxypropyl guar, and carboxymethylhydroxyethyl cellulose.

Abstract: The heterogeneous catalyst system consists of a catalytically active component and a porous silica support material having a large surface area; the support material is highly pure silica produced from glass bodies of large surface area by leaching with a mineral acid. Silica-containing materials are converted with suitable additives into a homogeneous glass phase and the glass bodies having a large surface area are produced from the latter. After the leaching, highly pure silica of large surface area is obtained which, provided with a catalytically active component, gives a reactive, high temperature-resistant catalyst which can be universally used. <IMAGE>

For connecting the waste gas pipe (32) to a waste gas connection piece (16) on the water heater, a sleeve (36) is provided, which can be displaced downwards on the connection piece (16) so far that the connection elbow (30) can be pushed or pivoted over the waste gas connection piece (16) and the sleeve (36) from the front. A fresh air opening (22) of the fresh air chamber (20) is surrounded by a collar (24), the rear annular half (56) of which surrounds the fresh air pipe (34) and the front annular half (54) of which is axially so deeply recessed that it does not hinder the pushing or pivoting of the connection elbow (30) onto the connection piece (16). The fresh air pipe (34) is subsequently clamped tight on the collar (24) by means of a clamp (38). This results in simple assembly of the parts, in which only one sleeve (36) has to be displaced and one clamp (38) has to be applied. <IMAGE>

Abstract: A random-access memory has a plurality of memory cells (12ij). Each cell (12ij) includes a magnetic storage element (30). The magnetic storage element (30) includes a thin film of magnetic material (74) disposed on a semiconductor substrate (70) and having further disposed thereon transistors (22a,22b) connected in a flip-flop configuration. The thin magnetic film (74) has different remanent magnetization states used for information storage. A pair of strip conductors (78,79) used to provide connections (23) to the flip-flop configuration of the transistors (22a,22b) are magneticaly coupled to the remanent magnetization states. One of the currents (123a,123b) passed to the gates of the flip-flop transistors (22a,22b) is delayed by one of the remanent states relative to the other current so that the state of the flip-flop is determined by the state of the magnetic storage element (30). Preferably a pair of mutually orthogonal remanent states is used for information storage to give the storage cell a relatively high frequency response.

Abstract: A communication protocol is provided to enable one of a number of transmitters using a common transmission line to independently gain exclusive use of the line. Before transmitting data, a transmitter first monitors the line to establish that it is idle. If it is, the transmitter then asserts the line for an interval unique to that given device. Thereafter the transmitter monitors the device momentarily to determine that no other transmitter is asserting the line and, if so, the transmitter may then gain exclusive control of the line.
