Patent CA-2128298-C (CA)
Inventor: BURGE THEODOR A
IPC: C04B24/12
Filed: 1994-07-18
Granted: 2004-06-29
Abstract: Additives are disclosed which inhibit the corrosion of metals in construction materials which contain an inorganic binder. The inventive corrosion inhibitors contain a reaction product of amines and acids or they consist of such a reaction product. Said saltlike corrosion inhibitors upon use do not develop any undesired fragrance, and they furthermore do not bring along any health risks for the persons who are working with said substances. Through the adding of the inventive corrosion inhibitors, furthermore the properties of the construction material during its preparation and also during its use can be improved. In corresponding processes for inhibiting the corrosion of metals which are in contact with the construction materials, like e.g. metal armings, the corrosion inhibitors are usually added in an amount of 0.01% by weight to 10% by weight of said reaction product, referred to the inorganic binder which is contained in such material. Construction materials which contain the inventive corrosion inhibitors provide a corrosion inhibition of any metal parts embedded into said construction materials over decades of years.

Granted: 2001-03-13
Abstract: A jet for use in spas and hydrotherapeutic reservoirs having a first set of nozzles aligned in a plane at the water entrance side of the jet and a second set of nozzles aligned one-to-one with the first set of nozzles at the water exit side of the jet. A chamber separates the two sets of nozzles and includes a slot which is used tointroduce air into the fluid stream. The amount of air introduced into the chamber is controlled by the user by rotating the jet within its housing from a maximum air intake position to a "no-air" intake position, air being introduced through a slot surrounded by a rectangular seal structure. A housing is provided to mount the jet within the wall of a spa comprising a rear wall mounting, an end cap, and a front wall mounting.Water is introduced to the multiple jet structure via a single horizontal water inlet. The servicing of multiple jets by the single water inlet and air line improves plumbing reliability and further reduces labor by minimizing the number of plumbing joints.

IPC: A61N1/362
Filed: 1996-06-04
Granted: 2001-10-02
Abstract: A method and apparatus for variable rate cardiac stimulation is disclosed, wherein sudden drops in the rate of delivery of stimulation pulses are avoided by means of rate smoothing and peak rate support functions. In one embodiment, circuitry in a cardiac pulse generator detects atrial events and maintains an updated value of the A-A time intervals between certain atrial events.  If the preset ratio or total of these A-A intervals are found to have been shorter than the updated value by at least a predetermined amount of time, a rate smoothing function is activated wherein the rate of delivery of stimulating pulses is prevented from changing, from cycle to cycle, by more than a predetermined maximum amount.  A peak rate support function preferably employs the same updated value in the computation of "escape" intervals. Following the latest A-A interval, if that A-A interval is less than the updated value, then the updated value is used as the new escape interval.  If the latest A-A interval is greater than or equal to the updated value but less than the previous updated value, the current escape interval is used as the new escape interval. If the latest A-A interval is less than both the previous updated volume and the current updated value, the [current] value updated is used as the new escape interval, and the pulse generator enters a decay mode wherein the escape interval is gradually and incrementally lengthened to prevent sudden changes in the rate of delivery of stimulation pulses.
