even keel almost directly over its anchor point at any altitude up to 2,000 feet.

The device comes packed in an advertising kit complete with everything needed for operation except a cylinder of helium, which should be obtainable inexpensively in any medium-sized town. The kit includes two white nylon panels on which advertising matter can be printed, and which attach to the sides of the balloon, plus an eight-foot hanging nylon banner, also designed to carry advertising. Decorative effect may be heightened by attaching a small string of pennants to the anchor line.

Flexible Sheef Mirrors

A new line of flexible sheet mirrors, said to be designed for decorative use on flat, convex, or concave surfaces, is manufactured by National Products, Inc. According to the manufacturer, 3 wide range of colors and patterns gives virtually unlimited scope in the creation of decorative effects heretofore considered almost impossible.

The mirrors are made of real glass and pure lead backing, and special treatment assures longest mirror brilliance. After cloth is applied to the. back of the uncut mirror, the desired square or rectangular tile shapes are cut, and the edges spin cially processed to give, added lustre. Top-quality waterproof adhesive enables the mirrors to be used even where atmospheric conditions are difficult.

Oufdoor Past and Wall Lighfs

A new line of outdoor fluorescent post and wall lights, said to provide considerably more light at greatly decreased cost, has recently been announced by Great Northern Manufacturing Corporation.

According to the manufacturer, the units are constructed for year-round, allweather operation and may be seen through fog or haze. Both types of fixtures are said to come ready for easy installation. Although they were first tested and won immediate success in illuminating gasoline service stations, it is reported that they have also been found invaluable in brightening frontal areas of roofed theatres and drive-ins as well as other types of businesses.


Incandescent Spailighf

A new incandescent spotlight, known as the Trouperette, has been developed by the Strong Electric Corporation for use in small theatres, night clubs, schools, television studios, industrial shows, conventions, etc., where physical dimensions and price are factors and

where the tremendous volume of light of an arc lamp is not necessary.

A highly efiicient optical system is said to enable the unit to project far more light than is possible with any conventional incandescent spotlight. This increased brilliancy is made possible by a variable focal length objective lens system, a 5%-inch silvered glass reflector, and Fresnel lens used with a standard 11l5-volt, 1,000-watt prefocused projection type bulb.

The variable focal length objective lens system affords the advantage of retaining the same sharply defined edge, of any size spot, from head to fIOOd, without refocusing.

The new spotlight projects a minimum spot diameter of 1/100 of the length of throw and a maximum spot diameter of 1/3 the length of throw. It is provided with horizontal masking control, which can be angled at 45 degrees in each direction, and a fast-operating color boomerang which accommodates six slides. Horizontal sweep of the spot is possible throughout 360 degrees, and all operations of the lamp are extremely simple, according to the manufacturer.


Continuous Carbon Burner

A new continuous carbon burner, developed by Hanover, Inc., is an automatic device designed to do more than just conserve carbon.

First of all, it is claimed to cut carbon costs in regular operation by approximately 25 per cent. Secondly, it enables the operator to burn any discarded carbon waste that may have accumulated. Thus, the burner promises to
