Title: Gas laser having thermally stable optical mount
IPC: H01S3/0971
Filed: 1986-01-22
Abstract: A laser of the flowing gas type employs an optical resonator having mirrors at each end of the lasing region which are supported, without a separate optical bench, by a hollow cylindrical gas-tight housing. Enclosed in the housing are a pump for circulating the gas, electrodes for causing lasing of the flowing gas, and heat exchangers for cooling the gas. Those enclosed structures are subject to thermal expansion and contraction and are hung between a pair of plates. One of those plates is affixed to one end of the housing while the other plate is free to move within the housing so that thermal expansion and contraction of the enclosed structures does not place an appreciable stress on the housing. A heat shield is disposed between the hung structures and the inside wall of the housing to provide a barrier to the transmission of heat to the housing and the housing is liquid cooled to stabilize its temperature. The mirrors of the optical resonator are mounted on rings attached to each end of the housing. Apertures are provided in the plates to provide windows for the passage of light reflected between the mirrors of the optical resonator. At least one of the mirrors is mounted so that its alignment can be adjusted without opening the gas tight housing.

Title: Valve cover for the cylinder head of an internal-combustion engine
IPC: F02B77/00
Filed: 1987-11-11
Abstract: A cylinder head cover wherein the pan-shaped metallic body has a marginal portion with a groove for a portion of a gasket which is formed on the marginal portion prior to attachment of the cover to the cylinder head of an internal combustion engine. The underside of the marginal portion is coated with one or more layers of a coupling agent and a mold is placed over the marginal portion to define therewith an endless cavity which receives a supply of plasticized silicon rubber at an elevated temperature. The injected material is then heated to vulcanization temperature and is thereupon allowed or caused to set by cooling so that it forms an elastic sealing ring which is bonded to the marginal portion of the cover by the coupling agent. The mold is then removed from the marginal portion and the cover is secured to the cylinder head by fasteners which extend through the bottom wall of the pan-shaped body and are surrounded by noise-damping elastic sealing rings.

dielectric is positioned between the electrodes, and the 
dielectric has a structure defining an ionically conductive 
surface. An apparatus for measuring the corrosion rates of

corrosion rates of metals in a corrosive liquid environment 
comprising attaching electrically the corrosion probe to a 
potentiostat. The corrosion probe is inserted into the corrosive 
liquid environment and either a predetermined known current is 
signaled to the potentiostat or a predetermined known difference 
in potential is signaled to the potentiostat. The potentiostat 
transmits the current, or applies the difference in potential, to 
the corrosion probe. An electromotive force between the first 
electrode and an area in the corrosive liquid environment in 
general microscopic proximity to the first electrode is 
determined. The corrosion current is computed from the determined 
electromotive force and the measured amperage. The probe may be 
utilized to detect electrochemically active components in a 
generally nonionic conductive fluid.
