VENTILATION AND HEATING.— Apart, however, from the alteration
of the physical characteristics of a house, an important factor in any modernisation scheme is the installation of suitable ventilating equipment. Considerable attention is now being paid by local authorities to this matter, which is also a great factor in audience comfort. In the case of the kinema seating over 1,000 patrons, the provision of a Plenum system will solve both the problems of ventilation and heating. In the smaller hall, a convenient method is the employment of extractor and intake fans in conjunction with a low-pressure water installation for heating.
CHEMICAL AIR-CLEANING.— The possibilities of Aerokleen, anew ventilating method, will repay examination, particularly by the small exhibitorAerokleen plants are supplied in various models to deal with theatres of 500 seating capacity up to 4,500. The apparatus is suspended near the stage or screen, and by means of chemical action purifies bad air, eliminates smoke, and introduces in their place a fresh, clean and disinfected atmosphere. The plant may be switched on overnight or during a performance, for its operation is absolutely noiseless, and without any odour. Consumption costs are as low as 3d. for the single purification of a 500 seater. The efficiency of the plant is indicated by the fact that more than 350 units have been installed by the Chemical Air Cleaning Co. within a few months.
THE ORGAN IN SHOWMANSHIP.
Notwithstanding the lead given by the large circuits in instalhng organs and the obvious popularity of well-known organists, there arises from time to time controversy as to whether the organ is really an essential to the modern kinema equipment, and whether, as a box-office attraction, it does, indeed, justify its expense.
The result of the recent questionnaire concerning films and music issued by Sidney Bernstein, proves definitely that the public looks for organ music in the theatre. Not less than 84.6 per cent, voted in favour cf the organ. The experience of other exhibitors also emphasises its popularity of the organ.
Such facts indicate the potentialities of a kinema organ, but, at the same time, the success or otherwise of the instrument largely depends upon the employment of a fully qualified organist who is musician enough to do full justice to the fine instrument he controls. The employment of underpaid or inefficient players will be just as much a house-emptier as the reverse is an assured business getter.
Perhaps the best indication of the demand for the organ is contained in the announcement that during 1934 the John Compton Organ Company, Ltd., achieved the record distinction of installing organs at the rate of one a week.
The illuminated console which Compton's were the first to introduce has revolutionised the art of organ presentation nowadays. Practically every new instrument is equipped with this type of console and many older instruments are being adapted. The use of the illuminated console is an integral feature of many kinema programmes and has evolved a new conception of the employment of colour varying intensities to suit musical
