Abstract:
A brake release for railroad cars allows all the brakes of a train to be released automatically instead of by the conventional, car by car method. The crewmember releasing the brakes does so by merely adjusting the air pressure in the train's air brake line to a predetermined level. The brake release system's valves open at this pressure allowing the system to be pressurized. This pressure provides the force needed to release the brakes when the pressure in the train's air brake line is released. The system then resets itself and is ready for its next use. This system can be installed on a rail car without interfering with the conventional method of releasing the brakes.

An inter-bank email and mobile invoicing network is disclosed. Embodiments disclosed herein include an inter-bank email and mobile invoicing network that enables customers of banks or independent portals to send invoices to an email address or mobile phone number. The invoice can be received by the recipient within their bank's online or mobile banking site, in the case of banks that belong to a network that is managed by the proprietors of a financial management system and payment hub as disclosed herein. These banks will be referred to as “network banks” herein. The inter-bank invoicing network also refers to a common provider or connected providers of an invoicing and payment service that is linked to banks and to independent service providers.
Abstract:
In a push-to-talk communication system, frames are sent by a talking device before confirmation that the device has the floor. These are flagged, sent for a limited duration and buffered in a listening device. Playback is triggered either by receipt of frames flagged as ‘confirmed’ or by receipt of the ‘receiving talk burst’ message from a server.
Abstract:
Clay-based compositions capable of absorbing contaminants from surfaces or objects having surface faces, may be applied to a surface and later removed, the removed clay-based compositions absorbing at least a portion of the contaminant from the surface or object to which it was applied.
Abstract:
The invention provides a method of handover from an active network to a selected one of a plurality of potential other networks. In addition to the overall solution, the solution proposed has several individual aspects. All subsidiary aspects are related to the common problem mentioned above and sharing the underlying common solution concept of implementing a system in which selective handover is possible and in which a list of available other networks provided by an active network can be handled and selection made by a terminal, so that neighbor cell information can be transmitted based on expressed terminal preferences.
Abstract:
Molecular sieves are prepared by forming a reaction mixture slurry, spray drying the reaction mixture slurry to form particles, and heating the spray dried reaction mixture at a temperature and pressure sufficient to cause crystallization of the molecular sieve. The reaction mixture contains an organic templating agent capable of forming the molecular sieve. The template may be added to the reaction mixture either by adding all of the template prior to spray drying, or by adding a portion of the template prior to spray drying with the remainder being added after spray drying.

Abstract:
The present invention relates to non-pathogenic strains of HIV-1 and to components, parts, fragments and derivatives thereof and to genetic sequences derived therefrom and their use in the development of diagnostic and therapeutic compositions for the treatment and prophylaxis of AIDS and AIDS-related disorders. The present invention also relates to a method for attenuating pathogenic strains of HIV-1 by mutagenizing particular regions of the HIV-1 genome.
Abstract:
A mechanical bladder pump is provided for collecting fluid samples from a well. The pump includes an outer tubular member having a longitudinal bore, and an inner tubular member arranged within the bore of the outer tubular member. The inner and outer tubular members are connected at their lower ends to a compressible bladder, and are arranged for oscillating movement relative to each other to expand and compress the bladder. The lower end of the bladder is open to an inlet passage, and the upper end of the bladder is open to an outlet passage. First and second check valves are provided to control the flow of fluid through the bladder during operation of the pump. A return spring is used to store energy during a tension stroke of the inner tubular member and to release energy during a compression stroke thereof. The pump provides highly representative samples of groundwater.
