Abstract: An apparatus and method for separating residual water from a solvent. The device comprises a reservoir containing a solution comprising solvent containing residual water, the reservoir having an opening to allow the solution to drain from the reservoir. A membrane layer is provided comprising a layer of fluropolymer material, said membrane material having a IPA Bubble Point of ≧25 psi. The membrane is positioned in series with the reservoir opening. Vacuum is generated on one side of the membrane layer wherein the solvent containing water passes through the membrane therein removing water from the solvent to provide a solvent with a water level of less than or equal to 1.0 ppm.

Abstract: An evaporator comprises a base with a vacuum connection. A tray is fixed to the base, and has seating positions in which to seat pans which hold sample liquid. A transparent cover is attached to the base with a hinge. The cover fits over the tray and when closed forms a tight fit with the base and is in close proximity to the pans. The cover has inlets angled down at about 37° to 42° over each pan seating position such that when a vacuum source is connected to the vacuum connection, air from outside the evaporator is drawn in through the inlets and aimed toward the sample liquid in each pan such that the solvent evaporates. Pans are preferably commercially available pans which are about 70 mm in diameter and about 16 mm in height, and tapered outwardly towards the top. Preferably, the cover has two inlets for each pan, aimed in opposite directions, and on opposite sides of each pan, such that when air strikes the sample liquid it induces a swirling motion.

Abstract: An improved automatic filtration and extraction device is disclosed which comprises a base defining at a top end a cavity area which tapers downwardly and inwardly from the top end to define a chamber for a portion and then defines a plurality of effluent outlets at the bottom end each extending from the chamber to an outer surface of the body. Seals are adapted to each of the effluent outlets and are moveable between a first closed position sealing the effluent outlet and a second open position to allow the passage of effluent through the effluent outlet. A filter is detachably and removably adapted over the cavity area. Various solvents are provided to the cavity area through a solvent provider. A circuit with programmable memory accesses and directs a sequence of events after an initial event. A vacuum connected to each of the effluent outlets each induces effluent flow through an effluent outlet while sealing all other outlets.

Abstract: An improved automatic filtration and extraction device is disclosed which comprises a base 17 defining at a top end a broadened cavity area which tapers downwardly and inwardly from the top end to define a chamber for a portion and then defines a plurality of effluent outlets at the bottom end each extending from the chamber to an outer surface of the body. Sealers 42 are adapted to each of the effluent outlets and are moveable between a first closed position sealing the effluent outlet and a second open position to allow the passage of effluent through the effluent outlet. A filter 110 is detachably and removeably adapted over the broadened cavity area. A solvent provider 90 is adapted to the base whereby various solvents are provided to the broadened cavity area. A circuit 200 is connected at one end to a power source, and the programmable memory to access and direct the sequence of events after an initial event. A programmable memory is provided for a sequence of events and is connected to the base.

Abstract: The cylinder head assembly includes a cast member, and a substantially planar member that is affixed to an upper end of the cast member. The substantially planar member includes apertures to anchor the intake and exhaust rocker studs, apertures that receive the intake and exhaust valve, and apertures that receive the push rod guides. The substantially planar member also has spring locators for the intake and exhaust valve return springs. The cast member is affixed to the engine cylinder, and includes cast intake and exhaust manifolds, bosses for receiving the intake and exhaust valves, a cast pocket for receiving the intake and exhaust push rods, and air cooling fins. A head cover is disposed on an opposite side of the planar member. The invention eliminates the need for two cast components.

Abstract: A cooling system for neck ring molds in a glass molding machine having retractable parison-forming molds engageable with the neck rings employs air jets directed at exposed portions of the neck ring molds. The neck ring molds are configured to extend out of the bottom of the main parison mold and to engage with neck ring hangers. The neck ring molds are configured sufficiently long that a space is created between the bottoms of the main parison molds and the hangers to permit direct access to portions of the neck ring mold. Air supplied in the form of air jets from a pair of cooling air plenums is directed at the exposed portions of the neck ring molds to provide cooling.

Abstract: Oleaginous compositions comprising a fuel oil or a lubricating oil, a friction modifying amount of a hydroxy ether amine compound such as that having the formula: ##STR1## where X is O or S, R.sub.3 is H, R.sub.1 is C.sub.18 alkylene, R.sub.2 is C.sub.3 alkylene, and R.sub.4 and R.sub.5 are C.sub.2 alkylene, and, optionally an amount effective to impart anti-wear properties to the composition of an organic phosphite ester, such as triphenyl phosphite, are disclosed.

Abstract: A roller mop having a wringer assembly connected to a handle and a cleaning element mounted in the wringer assembly for reciprocation through a pair of rollers in a direction that is transverse to the longitudinal axis of the handle. The cleaning element is reciprocated by a retraction rod that has upper and lower arms that are angled relative to one another. The lower arm is oriented to exert a pulling force upon the cleaning element that is directed at an angle relative to the axis of reciprocation. To counteract a nonproductive component of the exerted force that tends to bind the cleaning element, the lower arm is arranged to engage a bearing surface that in included on the wringer assembly.
