Abstract: The present invention relates to the use of aqueous compositions at ambient temperatures to clean, disinfect and preserve contact lenses. It has been a problem that when prior aqueous compositions contain anti-microbial constituents at active concentrations, these constituents tend to be absorbed or concentrated by the lens (particularly soft contact lenses), resulting in damage to the lens or harm to the eye of the user.The present invention provides a composition that is active against a wide variety of microorganisms yet is compatible with soft contact lenses as well as non-irritating and safe for contact with the human eye.The composition includes glyceryl monolaurate in combination with one or more other anti-microbial agents, and optionally an organic surfactant, for use in a solution for cleaning, disinfecting and preserving contact lenses.

Abstract: Clamping cylinder 22 slidably receives a clamping ram 26 whose front end is fixed on a movable board 20 of (e.g.) an injection molding machine (21,23-25) and which has a chamber opening in its rear face. The interior of the clamping cylinder 22 is divided into a rear chamber W and a front chamber X by the large-diameter piston section of the clamping ram 26. From the inner rear wall of the clamping cylinder 22 there projects, a mold opening piston having a front end which slidably fits in the chamber in the clamping ram 26. The opening piston has a large-diameter piston section which divides the chamber into a rear chamber Y and a front chamber Z which communicates with the atmosphere. A hydraulic controlling device 31-37 controls the connection of the chambers X,Y and Z to each other and to an oil pressure source 40. Thus it connects the chambers X and Y to the chamber W for high-speed mold closure. It connects the chamber W to the oil pressure source 40 and relieves the pressure in the chambers X and Y for tight clamping; and it connects the chamber Y to the oil pressure source and connects the chamber W to both the chamber X and the relief means 32 for opening the mold. Preferably, the effective pressure receiving area of the chamber Y is to be equal to the cross-sectional area of the chamber section of the clamping ram 26.

Abstract: A method for selecting amino acid residues is disclosed which upon replacement will give rise to an enzyme with an altered pH optimum. The method is specific for metalloenzymes which are inactivated at low pH due to the dissociation of the metal ions. The method is based on altering the pKa of the metal coordinating ligands or altering the Kass for the metal binding. New glucose isomerases with an altered pH optimum are provided according to this method. These altered properties enable starch degradation to be performed at lower pH values.

Abstract: A power control system for a cellular mobile telephone system in which system users communicate information signals between one another via at least one cell site using code division multiple access spread spectrum communication signals. The power control system controls transmission signal power for each cellular mobile telephone in the cellular mobile telephone system wherein each cellular mobile telephone has an antenna, transmitter and receiver and each cell-site also has an antenna, transmitter and receiver. Cell-site transmitted signal power is measured as received at the mobile unit. Transmitter power is adjusted at the mobile unit in an opposite manner with respect to increases and decreases in received signal power. A power control feedback scheme may also be utilized. At the cell-site communicating with the mobile unit, the mobile unit transmitted power is measured as received at the cell-site. A command signal is generated at the cell-site and transmitted to the mobile unit for further adjusting mobile unit transmitter power corresponding to deviations in the cell site received signal power. The feedback scheme is used to further adjust the mobile unit transmitter power so that mobile unit transmitted signals arrive at the cell-site at a desired power level.

Abstract: A mechanical anti-theft device of the type applied to the steering wheel of an automotive vehicle which automatically ratchets to it's applied position without necessity of key lock actuation is provided with several security enhancing features which cumulatively prevent or make the device exceedingly difficult to unlock using conventional burglary tools or lock picking techniques. The features include configuring the ratchet teeth of the telescoping rod member in a way which minimizes any attempt to deactivate the lock unless the key is used. In combination with the ratchet teeth configuration, the lock pawl mechanism is configured to include an arcuate, transversely extending apex edge line or surface which cooperates with or is sized to be coincident with the rod members circumference to prevent a wedge, shim or pick from being readily easily inserted between pawl and ratchet tooth to force a retraction of the pawl.
