The instant invention pertains to a road vehicle's axial flow cooling fan which normally draws cooling air from in front of the vehicle and blows it into the engine bay. The instant invention includes a control circuit for the fan motor that provides variable speed and bi-directional, or reverse and normal, fan operation. Reverse fan operation blows air from the engine bay through the radiator and out the front of the vehicle, and normal fan operation blows into the engine bay. Two input sensors feed the control circuit, one for road speed of the vehicle and other for engine temperature. When the engine is below its operating temperature and the vehicle is moving, the fan is made to blows in reverse at a speed proportional to road speed so as to block cold ram air from entering and blasting onto a warming engine. This speeds engine warm-up to reduce emissions, improve fuel economy, and speed windshield defogging. The fan may also be made to blow in reverse when the engine is cold and the vehicle is stopped, in order that exhaust-heated air from the exhaust manifold behind the engine, may be drawn forward over the engine block to speed its warming. When the engine is above its operating temperature and the vehicle is idling or moving slowly, as in traffic, then the control circuit causes the fan to again blow in reverse cooling both the radiator and the engine bay components and preventing hot, noxious fumes from vehicles in front from being drawn into the vehicle. Blowing in reverse in traffic conditions also eliminates hot air looping back to the front of the car and drawn in through the radiator. As vehicle speed increases, the fan is made to revert to normal operation augmenting ram air flow through the radiator.

A premium ventilated toilet having an automated toilet ventilation system for removing noxious fumes from a bowl area of the toilet is disclosed. The ventilation system is mostly built-in to the toilet (e.g., ventilation ducts, and sensors) so that it is unobtrusive and attractive looking, however the active parts (e.g., a blower unit containing a blower impeller, a backflow shutoff valve, and electronic control circuitry) are contained in an simple housing that is unobtrusively and removably attached to the surface (preferably on the side) of the toilet base for simplified installation, maintenance, and replacement as needed. Automated operation is enabled by a non-contact occupancy (proximity) sensor and a flush sensor, both preferably built into a flush handle of the toilet. Detection of occupancy causes the ventilation system to operate and flushing turns it off.

The system embodying the invention is employed to cool the interior of a normally closed area such as a garage or storage area, and/or to remove any noxious fumes or undesirable odors from inside the garage by moving outside air into the garage and providing means for that inside air and the fumes or odors in it, if any, to be removed to the outside ambient atmosphere. The system includes one or more fans installed in the upper section of the garage door, and the garage door is opened or closed by moving it in any well-known manner either by rolling it's hinged panels upward to a horizontal position from its normally-closed vertical position, or, when it is a solid door, tilting the entire garage door so that it is substantially horizontal instead of vertical and is located above the garage floor a sufficient distance to drive vehicles that will fit into the garage though the door opening. Those fans have a power cord that extends from a power supply position generally near the garage door opener that is secured to the garage ceiling and powers the garage door from its closed position to its open position, and vice versa, and that power cord is also secured to the garage door in the vicinity of the fan or fans used to move air into and out of the garage when the garage door is closed. The power cord is spring-urged to minimize its relatively free section between the power source and the place where it is secured to the garage door in the vicinity of the fan or fans where it provides power to the fan motor or motors when desired and appropriate. In the preferred embodiment the power cord is wound on a reel that is spring loaded to urge the reel in the rotational direction to wind the part of the power cord that is between the reel and the fan motor or motors, keeping the relatively free section of the power cord in tension so that it does not form any dangerous hanging loops when the garage door is moving from its open position to its closed position. There are also lesser desirable alternatives to apply a spring-loading to the power cord to keep it sufficient tension that it does not form such loops when the garage door is being opened.

The device burns clean with a minimum of smoke and harmful or noxious fumes. Burning the device minimally creates air pollution. It burns completely with a minimum of ash residue.

The problem of noxious fume generation during chemical treatment of hair using a hair iron is solved by providing a fume intake on the hair iron near the point of fume generation, preferably near the iron's heating elements. The fume intake receives the fumes and delivers them to the fume removal passage under vacuum flow generated by a vacuum source, then transported to a filtration system or exhausted to the outside environment. Optionally, the fume intake may extend along the length of the heating element and may be directed downward, towards the hair. Optionally, the fume removal device may be attachable as a retrofit to a standard hair iron. The present invention advantageously prevents the spread of the noxious fumes to the rest of the salon and protects both the stylist and client from discomfort and irritation, thus permitting the more widespread use of these beneficial hair treatments.

An apparatus is provided which can easily, efficiently, reliably and thoroughly blend or mix hair colorant chemicals while minimizing stylist exposure to noxious fumes. The apparatus may include a mixing bowl molded from a polymeric material, an interlocking lid molded from the same or similar polymer, a specially designed top lid, a motorized handle, and a stiffing paddle or whisk having a rotatable shaft which passes through a sealing means removably affixed to the specially designed top lid and thence engaging a driving end of the motorized handle. The top lid incorporates interlocking means at its outer edge such that it can be easily twist-locked into intimate contact with the bowl which is provided with mating lock surfaces. When engaged, mating surfaces of the top lid and bowl form a seal which prevents or minimizes escape of mixture ingredients and odors from the enclosed volume defined by and between the lid and the bowl.

Disclosed is an area sensor for air quality in the cockpit, crew rest or other area of an aircraft. Noxious fumes, fuel vapors, carbon monoxide and other vapors can cause significant risks to the flight crew of an aircraft. Fumes may cause drowsiness, inattentiveness or confusion to the pilot of an aircraft placing all persons on board an aircraft in danger. There exists a need to monitor and warn the cabin crew of such an event so that measures can be taken, such as donning an oxygen mask, to mitigate the fumes. Many of the vapors encountered that can cause this issue are colorless and/or odorless and therefore not always detected by the flight crew especially if they are in sufficient quantities and exposure is long enough to compromise the pilots cognitive skills.

A method for preparing a catalyst precursor for an olefin polymerization catalyst involves the use of aqueous or alcoholic solutions of a chromium salt and of boric acid and aluminium carboxylate for deposition onto an inorganic support material, such as a silica xerogel. The chromium salt, aluminium carboxylate and boric acid are sufficiently soluble for deposition from a single solution to be effective. The catalyst precursor can be activated by calcination to form a catalyst for homo- or co-polymerisation of alpha-olefins which has productivity and melt flow index for the resulting polymeror copolymer which is comparable to results obtained with catalysts prepared by prior art organometallic routes. The activation of the catalyst precursor gives reduced levels of toxic or noxious fumes during activation compared to use of organometallic sources of chromium or aluminium.
