Title: Ammonium sulfate for neutralization of inhibitory effects
Inventor: OELMULLER UWE
IPC: C12Q1/68
Filed: 2002-01-25
Abstract: Ribonucleic acid (RNA) is a substance synthesized biologically and synthetically. RNA serves many functions as information molecules, reaction substrate, reaction catalyst, recognition element, structural element etc. For most analysis methods and functions concerning RNA itself or RNA as an analysis tool the purity of RNA is important. That means that e.g., other molecules which bind the RNA are able to inhibit the analysis/function of/using the RNA molecule or destroy the structure of the RNA molecule. For this reason it is important to eliminate the inhibitory or destroying function of molecules binding to the RNA. Moreover stable secondary structures of RNA  often results in reduced function and analysis quality. Secondary structure depends on the environment of the RNA molecule. The present invention features the addition of ammonium sulfate (NH4)2SO4 to RNA in solution to eliminate the inhibitory or destroying effect of molecules binding to the RNA to be taken as information molecule, reaction substrate, reaction catalyst, recognition element, structural element etc. Furthermore (NH4)2SO4 solves secondary structures of RNA to make RNA more accessible to reactions and analysis.

Patent CA-2442662-A1 (CA)
Title: Fire and explosion suppression
Inventor: GRIGG JULIAN
IPC: A62C2/00
Filed: 2002-03-28
Abstract: A fire or explosion suppression system comprises a source (30) of a liquid suppressant under pressure, and a source (32) of an inert gas under pressure.  The liquid suppressant is a chemical substance having a low environmental impact, with a short atmospheric lifetime of less than 30 days. The inert gas may be nitrogen, carbon dioxide, argon, neon or helium or mixtures of any two or more of them. The suppressant and the inert gas are fed under pressure to an output unit (34) comprising a mixing chamber in which the liquid and the gas impinge to produce a mist of the liquid suppressant of very small droplet size which is entrained in the pressurised gas together with vapour from the liquid, the so-entrained mist and vapour and the gas being discharged by a nozzle (44) into an area to be protected. The mist and vapour are therefore carried by the entraining and transporting high pressure gas into regions of the areas to be protected, enabling a total flooding capability. The inert gas also performs a fire or explosion suppressing capability.

IPC: G06Q10/02
Filed: 2003-09-30
Abstract: In a parking system having one or more payment terminals for receiving payment for parking spaces, an information processing centre for receiving transaction and alarm information from the payment terminals, one or more enforcement terminals and a two-way telecommunications network for transmitting information in real time between the information processing centre and the payment and the enforcement terminals, an enforcement system and a method where a minimal amount of data is sent to enforcement terminals while in use in the field. The enforcement terminals are preloaded with parking space graphic. Occupancy data, which includes only the data necessary to provide expiry information such as, for instance, a data bit for each space indicating if it is "paid" or if it is "expired", is transmitted in real time to the enforcement terminal. The occupancy data may be transmitted periodically or on demand by the enforcement terminal. In this approach, significant data packet network costs can be saved as the network costs are usually based on volume of data flow.
