Lifts and Elevators for Orchestra, Organ and Stage With the advance in showmanship many new types of equipment have become factors in motion picture presentation and its supplementary entertainment. Not the least of these new factors are the lifts and elevators which play such an important part in the success of programs today. The modern theatre has this equipment.

Lighting Control Equipment The modern theatre, with a well balanced and effective lighting system, has made many demands on the manufacturers of lighting control equipment. Elaborate color effects must be possible and to change the lighting and gradually merge the light from one color to another without attracting the audience a very flexible control system is required. Even the small control systems permit the operator to produce hundreds of color shades. Generally each color group has its own master control which is crossinterlocked with the ground master wheel device. Efficient control systems are available for every size house, no matter how >mall or how large. FRANK ADAM ELECTRIC COMPANY, 3650 Windsor avenue, St. Louis, Mo.

It is significant, however, that a number of leading manufacturers have established special departments to give time and attention to the subject of theatre lighting and fixtures.

It is said that the financial loss suffered by admissions returned by a theatre through only one power failure a year would more than compensate for the cost of equipment of this type. In addition to financial loss, a power failure during a performance frequently results in loss of life and property through the resultant panic. Emergency lighting plants are made in several types such as the gasoline engine type and the battery charged type with motor generator. In the instance of the latter several sources of power are provided to meet every contingency, which, together, form an interlocking type of protection. The first source of power for the emergency lights of the theatre is the regular powei supply, either from central station lines or from private generating plant. In some states it is required that the emergency exit lights be upon a 32-volt circuit in which case the circuit is fed from the A. C. lines, through a small transformer which is a part of the system. The second source for the emergency exit lighting is the special heavy-duty glass jar storage battery of the system. Depending upon the individual requirements of the installation, this battery and the auxiliary apparatus is of sufficient capacity to carry the total necessary load for periods as long as 8 hours. The third source of supply for the emergency exit lights is the motor generator set itself. In case the A. C. transformer circuit, which normally feeds the 32-volt exit lights, should fail the motor generator set is operated from the main power supply line and connected to the emergency exit light circuits through the battery circuit. The battery will carry the exit lights only as long as necessary to start the motor generator set. After the motor generator is started the battery floats on the line. The heavy-duty storage battery is kept continuously charged by means of a motor generator set, which is operated from the regular power lines, on an individual circuit separate from the emergency exit light circuits.

Lights, Spot Are made in arc and incandescent types for use on stage — in the booth — in cove lighting, and for head spotting. Most spotlights on the market can be used for spot lighting and for full flood. The arc types are made in sizes of 35 ampere up to 150 ampere. They come complete with stand and attachment cord and connector. Within the last year, the high in
