Abstract: Substituted 1 - amino - ar - tetrahydro - 2 - naphthols of the formula <FORM:0647209/IV (b)/1> are prepared by hydrolysing the corresponding naphthoxazolones of the formula <FORM:0647209/IV (b)/2> where y represents a halogen, nitro, amino, hydroxy, cyano, thiocyano or sulphonic acid radical.  The halogen may be chlorine, bromine, fluorine or iodine.  The hydrolysis may be effected with a dilute aqueous alkali or mineral acid, preferably in an inert atmosphere such as nitrogen or carbon dioxide.  Suitable hydrolysing agents are alkali hydroxides and carbonates and alkaline earth hydroxides, particularly calcium hydroxide, also hydrochloric, sulphuric and phosphoric acids.  The solution is neutralized after hydrolysis, when the product is precipitated. If an alkaline earth compound has been used for the hydrolysis, this may be precipitated with alkali carbonate, the alkaline solution filtered off and neutralized with acid to precipitate the desired product.  Examples show the preparation of the 4-nitro- and 4-chloro-compounds.  The starting materials are prepared as described in Specification 647,210, except in the case of the fluoro and iodo compounds and the sulphonic acid, whose preparation is described in that Specification as open to inspection under Sect. 91.

[Class 98 (ii).] Composite kinematograph pictures are produced by transporting a kinematograph camera before a background scene with the camera directed obliquely to its path of travel, and then photographing the foreground component in combination with the photograph of the recorded background scene with a camera set to view the foreground component at the same angle to the apparent path of travel of the foreground component as the camera employed for the background scene bore to its path of travel. Thus a background scene, Fig. 1, is photographed by means of a camera 1 mounted on a car 2 and the inclination, height, tilt and speed of the camera 1 and the speed of the car 2 are noted. A positive print of the background scene is projected by a projector 10, Fig. 2, on to a translucent screen 11 in front of which is disposed a vehicle 12 arranged parallel to the apparent direction of the projected background scene, and the vehicle and projected background scene are photographed by a camera 13, driven synchronously with the projector 10, and arranged at the same height and tilt as the camera 1, Fig. 1. To simulate road conditions, the vehicle is jostled, e.g. by an assistant on the running board or by means of a lever ; alternatively, as shown in Fig. 5, the vehicle 16 is mounted upon a platform 17 supported upon a central spherical bearing 18 and upon corner springs 22, which platform is suitably rocked. Appropriate directions for manipulating the vehicle controls may be indicated to the actor driver by directing the car towards the projected scene, by means of a small duplicate projector and screen arranged within the vehicle, or by means of a cue sheet and signal lights on the dashboard ; alternatively, the action is photographed without recording the sound and the driver is cued by the director. Composite pictures may be produced in natural colours by using a suitable colour camera.

Title: Liquid droplet recording apparatus
IPC: B41J2/08
Filed: 1976-06-09
Abstract: In order to improve the aerodynamic conditions when printing with ink jet printers, protective droplets are inserted, according to a predetermined pattern, into the sequences of droplets intended for printing. In this process, the number of protective droplets to be inserted between every two printing droplets is dependent on the position of the droplets in the sequence. The ink jet printer has control circuits which comprise a shift register (83) whose memory locations contain in each case the character information assigned to the droplet positions of a coordinate of the character matrix, and circuits (100, 101, 106) for controlling the sequences of droplets for the white and black segments of the characters. The output of one of the control circuits (101) is connected to the shift input of the shift register (83) in order to interrupt the continuation of the same during the production of the protective droplets. <IMAGE>
