Page 6 HEAT CORES HE majority of complete air conditioning systems now operating in theatres include heating and winter air conditioning. Thus, when the compressor and cooling sections have been shut-down, the heating coils and controls should be inspected before winter operation starts. A great deal of care for the heating coils is not required, so we will just mention the obvious points: 1. Brush off the surface of the coils once or twice during the Revivals In New York Algiers—1938 romantic drama; Boyer, Lamarr, Gurie. Bluebeard’s Eighth Wife—1938 comedy-romance; Colbert & G. Cooper. Dark Command—1940 romantic western melodrama; W. Pidgeon, C. Trevor. Divorce of Lady X—1938 technicolor comedy; L. Olivier, M. Oberon.

(LAST ARTICLE) How to Guard Against Trouble With the Ventilation System— Repairs Are A Problem Now season, or as necessary. 2. Check the stem traps to make sure that they are not stuck or otherwise not functioning. If there is a cold coil or if a section of the coil remains cold, have the plumber or steamfitter check the steam line and traps. FILTERS Te filters on any air conditioning job should have constant attention and be kept clean. A dirty filter will choke up the system and thus overload the motors. If your system is equipped with throw-away type filters, special attention should be given to this section. Filters of this type should not be used after they have become dirty. It is false economy to continue to use dirty filters. For economical and efficient operation the permanent type filter that can be washed with water will last indefinitely if given regular attention. The permanent filter is generally scientifically designed to have a much higher dust holding capacity and greater free air passage, thus eliminating the hazard of a clogged system and motor overload. GENERAL INFORMATION (Ce ean operation of the system will prolong its normal life. Don’t expect the ventilating, comfort cooling, or air conditioning system to dance a jig or do more than one has a right to expect from it. Just as one would not expect to run an automobile constantly at a 70 mile per hour speed, so one should exercise judgment in operation of his mechanical equipment. ue Ba % HE blower, the ticker or “heart” of the system from the standpoint of aid handling, was designed by its manufacturer to operate at a certain normal speed. Do not attempt to increase this speed beyond what is recommended by the blower manufacturer. Not only will that cause more wear on the blower shaft and bearings, but it may likely overload the motor. If there is reason to believe that the motor is not functioning properly or is becoming overheated, shut it off and call in an electrician. He can take an ammeter reading which will show exactly the wattage the motor is drawing. He can then compare that with the nameplate rating shown on the motor itself, to determine if it is overloaded. A change in the pulley ee nts ratio between the blower pulley and motor pulley can then be made so that the blower speed will not be such as to overload the motor or, if required, one may have to get a larger motor to replace the one in use. While this is done the electrician should make sure that the type of control now used has overload protection builtin or that the line has been correctly fused to guard against motor overload. Accidental means can occasionally cause the motor to overload, such as a sudden release of air resistance (static pressure) against which the blower and pulley sizes were selected. Sometimes just leaving an equipment room door wide open will cause this release of pressure and a subsequent motor burn-out. As this article is being written there are no Governmental restrictions on the purchase or sales of blower equipment other than what might be caused by shortage of materials, such as bearings and belts, which are difficult to procure. If the present blower equipment is in such condition that, perhaps because of long wsage there is a probability it may give out, it still can be replaced. However, there is no need to become unduly excited if the blower is of modern design, built and installed within the last 8 or 10 years, and apparently is in good operating condition. Whether air washer and dehumidifiers can be replaced is difficult to state at present. This will depend upon the availability of galvanized steel. While copper bearing steel cannot be used except on defense applications, the use of galvanized iron has not been prohibited. At present, air washers and dehumidifiers are being built, and they may be available for some time to come. However, it must also be kept in mind that motors, starters and pumps are required for a complete system, and these items are becoming needed ‘more and more in the national defense program. Evaporative coolers are in production at least by one of the large manufacturers at present, and can be purchased for immediate installation as this article is written. Manufacturers in the air conditioning industry are doing their utmost to cooperate with the leaders of our Government in making available for defense purposes 4s much of their production facilities and inventories as can he utilized June 10th, 1942 4 for the national good. However, exhibitors may be assured that these same manufacturers are fully cognizant of their responsibility to every customer who has purchased equipment of its manufacture, and the industry as a whole is desirous of continuing to serve its theatre customers in every way possible consistent with the restrictions and material requirements of the fighting forces. Coast Committee On Conservation The motion picture’s constant awareness of the need for conservation of material was given added impetus when the Motion Picture Conservation Committee announced an extensive program to save millions of feet of raw film during the current production year. Estimates varied as to the actual amount of film to be cut down, but a great reduction of the 135,000,000 feet used last year was promised. In accepting chairmanship of ‘committee, M. C. Levee of Artists Managers Guild said, “We must have immediate action, not conversation. This industry is on its honor. We have a responsibilty in economy in use of film, and we must shoulder it no matter whom it affects.” George Murphy of Screen Actors Guild suggested that savings could be effected if actors would learn their lines better, if directors would make fewer takes and if all others would co-operate. Frank Tuttle of Screen Directors Guild said ‘‘the directors accept a large part of responsibility for economies, we hzve written to every member asking for suggestions. We must have more careful planning, shooting and entire revision of our old points of view.” One point emphasized was that there would be no letdown in quality of pictures, and it was predicted that the effort to save film as a means of helping in the nation’s war effort probably would result in new practices throughout industry — with better pictures through better planning, directing and general co-operative work all down the line. Allan Ladd Again Alan Ladd, who made such a hit in “This Gun for Hire,’ has been cast for one of the star roles of the best-seller, “Storm,” by Paramount. Ladd’s next appearance before the public will be as a sinister character in Dashiell Hammett’s, ‘The Glass Key.” ’
