COMMENT: It's not so much the amount of the prize as tlie chance to test their skill that draws listeners to contests of lliis nature. A Ghost of an Idea may be the beginning of a successful sales campaign. In this issue there is a collection of tried and tested programs. One of them may be adaptable to YOUR business. A representative of your local station will be glad to help you work it out. Too, members of Radio Showmanship Magazine staff are always glad to give assistance to advertisers. SHOW-MANUFACTURE New products and equipment to raise the broadcast performance level. GONE WITH THE WIND To effectively eliminate thumping and monkey chatter in radio broadcasting, other fields of quality sound reproduction, the ALTEC LANSING CORPORATION, Hollywood, Cal., has produced an entirely new version of a 70DB gain, five watt limiting amplifier. In actual operation the new amplifier permits a total input attenuation of 30DB in IDB steps; provides ten to one compression beyond the limiting point; permits a five to six DB limiting action without being apparent to the ear; permits limiting of up to 15 or 20 DB without distortion; provides a valuable safety factor in high power radio and public address installations, and effectively reduces over modulation without distortion. Freqwency characteristic: plus or minus one DB over a range of from 20 to 20 thousand cycles. COLOR PICTURES Improved projection of color pictures and cooler working conditions for motion picture and television actors are made possible by a new heatabsorbing, color-transmitting glass produced by the AMERICAN OPTICAL CO., Southbridge, Mass. When used as a heat screen in a projector, the new glass permits the projection of motion and still pictures in their original colors, thus permitting pictures to be reproduced on a screen as they are taken. At the same time, the glass absorbs heat, so that films and slides are protected against damage. The glass can also be used in spotlights and floodlights as a heat screen, with the glass absorbing almost 90 per cent of the heat. SOUND PROOF To reduce the amount of sound passing in or out through the doorways between the jams and threshold or floor, the EVANSTON SOUND-PROOF DOOR AND STOPS is made up of two 5-ply wood veneered sections, with interior insulation sheets of differing material, differing weights and differing degrees of stiffness, differing rates of sound absorption and sound reflection. These crack up and dissipate sound waves. A single action of the lever handles hermetically seals all cracks around the door. Stops are felt-mounted, soundproof, adjustable to door surface. Door is available in standard, high duty and special types. SIGNAL GENERATOR A new wide range signal generator for AM and FM is the latest product to be marketed by the SIMPSON ELECTRIC CO., Chicago. Known as SIMPSON MODEL 415, new generator is designed to be practically independent of line voltage fluctuation, with calibration stable regardless of wide variations in line voltage. Control of RF output through its entire range eliminates the necessity of a separate connection for high output. Modulation from 0 to 100 per cent, using either the 400 cycle internal sine wave or an external source. High fidelity modulation up to 100 pcr | cent from below 60 cycles per second to over 10 kilocycles per second with no unwanted frequency modulation. 208 RADIO SHOWMANSHIP
