Abstract: Systems and methods for controlling chlorinators for pools and spas are provided. A controller communicates with a processor positioned within a replaceable cell cartridge of a chlorinator, to allow for remote control and diagnosis of the chlorinator and/or cell cartridge. The cell cartridge stores, in non-volatile memory on board the cartridge, one or more parameters associated with the cartridge. The controller can obtain this information from the processor of the cell cartridge, and can use same to configure operation of the chlorinator. Information relating to remaining cell life can be updated by the controller and stored in the non-volatile memory of the cell cartridge. Electrical and software-based mechanisms are provided for ensuring operation of only compatible cell cartridges with the chlorinator. A system for remotely diagnosing errors associated with the chlorinator is also provided.

Abstract: A communication system comprises a signal generator, polarizer, signal combiner, transmitter, positioning device, and controller. The signal generator converts first and second received data streams into respective first and second orthogonal linearly polarized signals. The polarizer is at a first rotation angle and converts first and second orthogonal linearly polarized signals into, respectively, a first right-hand-circularly polarized (RHCP) signal and first left-hand circularly polarized (LHCP) signal, which are combined in signal combiner into a signal sent by transmitter to a receiver. The positioning device adjusts the first rotation angle to substantially increase isolation between third and fourth orthogonal linearly polarized signals at the receiver. The controller performs the real-time analysis of transmission loss and directs the positioning device to adjust the first rotation angle.

A first gas containing capsule is pierced by energy supplied either manually or by a compressed spring of the like and the gas from the pierced first capsule powers a second piercing pin which pierces a second gas containing capsule. This reduces the amount of externally applied energy which is necessary to operate the inflator while supplying the inflatable article with an amount of gas which is twice that contained in capsules which are normally used with inflators of the same general type.

Abstract: A method of and an apparatus for discharging containers of solubilized gas, e.g. acetylene, in which the gas is initially drawn as a preference stream from one container or group of containers (e.g. conventional acetylene bottles or tanks) and is fed to the consumer. When the pressure in the tank or tanks falls below a predetermined set point value, thereby indicating that the volume flow rate is less than the mean or average flow requirement, a second tank or group of tanks is connected to provide a complementary flow. The second tank or group of tanks supply the total requirement during replacement of the first tank or group and then forms the preference stream while the replacement tank or tanks of the first group provides the complementary stream.
