206 The Kinematograph Year Book. Jack Roe (Cinema Supplies), Ltd. — This progressive firm, which successfully introduced the Century projectors to this country, has had this side of its activities considerably curtailed owing to the complete cessation of the import of complete projectors and arc lamps. Before the war they were able to offer Century projectors, together with Ashcroft arcs, a combination unsurpassed in its own field, and exhibitors who took advantage of tbe judgment of the late Jack Roe are now reaping the benefit by being possessed of a most dependable ana efficient projection combination. The post war situation as regards these specialities is still obscure, but, meanwhile, the firm is active in its effort to help exhibitors to obtain the best results from the equipment they have already installed. New means and methods to achieve this end are constantly being employed, and the Roe service has now been expanded to embrace the supply and servicing of every form of projection equipment. With rheir own controlled workshops the company is in an exceptional position for servicing. Pathe Equipment, Ltd. — Operating efficiency and low maintenance which are the attractive features of the famous Ross mechanism are likely to be improved upon in their new model projector which is promised directly peacetime production is resumed. Meanwhile, the current models are doing admirable service in commercial and service establishments. Although the supplies available to Pathe are naturally limited at this stage maintenance and general servicing have been carried out to the fullest possible extent. Features of the G.C. model are : the gearing is totally enclosed ; bearings are bushed with self-lubricating bronze-bushes ; racking embodies the rotating cross-box system and is effected from a conveniently placed knob underneath the lens mount, and permits latitude for a full-frame adjustment. Both Maltese cross and intermittent sprocket are hardened and ground, the latter by Ross's unique system. The cross is of the well-chosen intermediate size. The sprocket is reversible. A rear shutter is, of course, used. The gate is of the parallel sliding type, and is mounted so that misalignment through wear is exceedingly improbable. The spool-boxes are 18 in. in diameter, providing ample space for the fingers around a 15-in. spool. The upper arm is adjustable for angle, so that on a steep projection rake the box does not overhang and increase the effective length of the machine. Bottom arms incorporate silent chain-drive take-up with self-adjusting clutch movement. The type D lamp embraces the general characteristics of the popular type 4i C," but the use of the larger mirror brings its performance into line with other high-intensity lamps and permits the use of " Suprex " carbons ; their average load varies from 40 to 65 amps., which renders them suitable to all theatres of standard capacities, and, it is claimed, provides H.I. projection at L.I. cost. The many uses to which an effects machine may be put are embodied in the Ross " Sceneograph," an efficient equipment which consists of a double optical lantern, employing two Ross vertical arc lamps each with separate controls. It possesses many refinements directed towards a threefold purpose inside of a single function. It combines the work of spot and floodlighting with dynamic and combined colours, scenic effect projector and lantern slide projector. Walturdaw Cinema Supply Co., Ltd.— Places at exhibitors service an organisation as little disturbed by war time as it can possibly be. They have carried on the reputation for service possessed by this firm for upwards of half a century. This long experience has contributed to the building up of a war-time organisation, highly efficient not only in range but in quality as well. All inquiries affecting projection, screen illumination and general electrical problems are invited. Fortunately there is yet a good stock of spares available, so that they have carried on a large business in the provision of rebuilt and reconditioned mechanism. Although Walturdaws have been busy in the equipment of many official theatres, they are in a position to aid exhibitors in any of their problems involving stage lighting and equipment,
