Abstract: A method is described for removing water and other protic impurities from an organic liquid electrolyte, wherein the organic liquid electrolyte is brought into contact with one or more insoluble alkali metal hydride(s) and the insoluble reaction by-products formed thereby are separated off.

Abstract: Methods and systems by which a client application program running on a mobile communications device can determine the telephone number associated with the mobile device and communicate the telephone number to a remote computing entity in a secure and verifiable fashion are presented herein. In one embodiment, a client application program running on a mobile device sends an SMS message to a remote server, allowing the remote server to determine the telephone number associated with the mobile device and return the determined number to the client application program in a SMS response message. A client application program running on a mobile device may also prove to a remote computing entity that the program is running on the device. The client program and remote entity may exchange information in SMS messages, and the client program may transmit information obtained from the remote entity to the remote server via WAP-based communications.

Abstract: The process described herein provides a simple and cost effective method for making crack free, high density thin ceramic film. The steps involve depositing a layer of a ceramic material on a porous or dense substrate. The deposited layer is compacted and then the resultant laminate is sintered to achieve a higher density than would have been possible without the pre-firing compaction step.

Abstract: Towing apparatuses suited for use with, for example, three-point hitches or quick hitches. At least some of the present towing apparatuses include a male hitch member that is positioned such that a force acting through the male hitch member (such as a force transmitted to the male hitch member through the female hitch member of the structure being towed) does not cause the particular towing apparatus to rotate about an axis along which the towing apparatus is pivotally coupled to a towing vehicle (such as through a three-point hitch or a quick hitch).
