232 The Kinematograph Year Book. fluorescent screen forms the front face of it and is scanned from behind, just as in the ordinary domestic receiver, instead of being scanned on its front face, as in the Eaird tube. The E.M.I, tube contains some revolutionary features which permit of the use of high potentials of the order of 50 kv., without unduly wide separation of the electrodes. The lens and tube are mounted on a pivoted housing, which can be tilted to suit the rake to the screen, the rest of the projector remaining horizontal. The projector unit contains also the final stages of vision amplification and the time-base circuits. On the back of it are about a couple of dozen control knobs. The projector unit is completely duplicated, and the two units are fed from duplicated amplifier racks. The first of these racks receives the input R.F. signals which are separated into the picture and sound amplifiers in the second rack. The third rack contains a monitor screen and its amplifiers. The E.H.T. unit also embodies some novel ideas and includes the two diodes which rectifv the output of the oilimmersed transformer and which obviates the necessity of enclosing E.H.T. units in cubicles. BOX OFFICE EQUIPMENT. AT this period when A.R.P. authorities frown upon any unnecessary congregation of persons and when black-out regulations increase the work and add to the financial responsibilities of theatre cashiers, it is essential that exhibitors should give the very closest attention to the provision of his ticket-issuing equipment. It is only by the use of automatic issuing machines that an exhibitor can speed up the functioning of the box office and prevent the causes which led to congestion in the vestibule, which, while only effecting inconvenience and irritation in peace time, become a source of real danger under present war conditions. Under these circumstances it is no wonder that there are but A^ery few exhibitors who have the temerity to advance reasons of economy against the employment of up-to-date methods of ticket issuing. AutcmaiiCket, Ltd. — In the same manner in which Automaticket revolutionised the issue of tickets in the box office, now the latest addition to the range of their equipment will transform the theatre checking system. As a result of constant research and experiment they have now developed a complete and definite check on ticket collection, thus perfecting beyond all shadow of doubt the famous Automaticket system of ticket control. This latest product is marketed under the name — Automaticket Checker. The final check comprises : — 1. Mechanical cutting in half lengthways of the tickets in single or multiple strips instead of tearing across by the checker. 2. Automatic recording of each ticket cut. 3. Remote recording of each ticket cut, in any desired location. 4. Lamp indication of each ticket cut. 5. Immediate check between ticket issue and collection. It is claimed that the Automaticket Checker will trace error or wastage at once and safeguards kinema employees. It is instantaneous in action, for it is possible to read the result while patrons are still entering the theatre, and it is entirely fraud-proof. Automaticket have, of course, introduced many refinements into their existing equipment, which has resulted in increased facility of operation and further enhanced its appearance. The value of a properly constructed sales register is fully appreciated by the modern theatre manager, for it records separately the issue of the several prices or denominations of ticket besides giving the total, and so enables the statistics and audit departments to obtain their information at any moment. Among the comprehensive series of equipment there are models to suit every possible requirement, but one of the most popular is the electrically operated Model " K " machine, claimed to be the fastest in existence. It is available in six sizes to issue from one to six different denominations of tickets. Ail issues are doubly checked and the machine can be locked against
