Date Feb. 7, 1991.The electronics industry demands that hydrogen peroxide for use therein be purified to very low levels of impurities, currently at the level of a few ppb for some impurities, or even lower. However, existing methods are either inherently unsafe because they bring concentrated hydrogen peroxide into contact with a concentrate of transition metal decomposition agents for peroxide and a purification resin which acts as a source of carbon, or are unable to attain the desired impurity level. In the instant purification process, the hydrogen peroxide solution is passed through a membrane having a very small pore size which contains an ion exchange resin that is capable of removing alkali and alkaline earth metal ions from solution. The feed solution in characterized in that it contains no more than a small proportion by weight of transition metals that catalyse hydrogen peroxide decomposition compared with the total metals content. The feed solution in some embodiments results from a prior treatment of an iron or copper contaminated solution with a dispersion of stannic oxide.

Abstract: A laser sight for a firearm (10) having a recoil spring guide (15) mounts components on the spring guide so that a light beam (18) is directed along the axis of the spring guide. This automatically makes light beam (18) parallel with the barrel (11) of firearm (10). Several mounting alternatives are possible, including a collimating lens (21) arranged on the axis of the spring guide to receive light from a laser diode (20) that is either mounted on the spring guide with the collimating lens or mounted remotely and arranged for directing light to collimating lens (21) via a fiber optic cable (25). These arrangements can also conceal the laser light within the firearm, where it is well protected and not noticeable.

Abstract: An echogenic medical devices adapted to be inserted into a patient, comprises an elongated member (123, 901, 1003) including a material (127, 1002) having an acoustic impedance different from that of the surrounding medium. For enhancing an image produced in response to a sonic beam produced from imaging equipment, the medium includes biological tissue or fluids surrounding the member when inserted into a passageway of the patient. The elongated member (901) also provides an interface (903) including the outside surface of the member and a plurality of partially spherical indentations (905). Alternatively, generally spherical particles (1002) are attached to the surface of the member (1003) for producing the image in response to the sonic beam. Materials such as stainless steel, plastic, and glass are utilized in the manufacture of the medical device. The device may also include an echogenic body member including a composite material echogenically imageable in the patient. The composite material includes a matrix material with discrete sound reflective particles made from a material different from the matrix material and embedded therein. Several sound reflective particles are disclosed, one type of particle being a glass microsphere about 5 microns in diameter. The matrix material (125) may be a plastic, and may be formed or extruded into devices such as catheters or other medical devices. The composite material may include different quantities of sound reflective particles by percent volume. Furthermore, a radiopaque material may be included in the composite material so the medical device is both ultrasonically imageable and radiographically imageable.

Abstract: The invention relates to an arrangement in an elongated working platform (2) which at each end is carried by a mast via a drive support (8) movable along the mast. The drive support includes an electric motor unit by means of which the drive support is drivable along the mast, said drive support pivotally carrying the corresponding end of the platform. At each motor unit an operating means for manual release of a motor brake for lowering the platform in case of power failure, is connected to a levelling device (24-38). The levelling device is arranged to be triggered in order to prevent movement of a drive support resulting in deviation of the platform from a position essentially corresponding to the horizontal position, said transmission being arranged to return the operating means to a position activating the motor brake, if the manual release of the motor brake causes triggering of the levelling device.

Abstract: A method for merging first and second digital video signals generated by first and second video controllers, respectively, for merged transmission to a digital video decoder. The first video controller transmits the first digital video signal to the decoder while monitoring the signal to detect a luminance component which designates the boundary between a first image constructable from the first video signal and a second image constructable from the second video signal. When the luminance component is detected, a colorkey signal is generated by the first video controller and transmitted to the second video controller to initiate transmission of the second digital video signal to the decoder in place of the first digital video signal. The first video controller continues to monitor the first video signal until the absence of the luminance component is detected. The first video controller then transmits a second colorkey signal to the second video controller to terminate the second digital video signal and transmission of the first digital video signal to the decoder recommences.
