Patent GB-634854-A (GB)
Title: Improvements in and relating to kinematographic projection with continuously moving film
IPC: G03B41/08
Filed: 1947-05-06
Abstract: 634,854. Kinematograph apparatus. SCOPHONY, Ltd., ADAMS, A. E., and COOK, G. H. May 6, 1947, No. 12274. Addition to 589,971. [Class 97 (i)] A kinematograph projector as set forth in the parent Specification comprises, as compensating means for the continuous film movement, two reflecting surfaces which are relatively inclined to each other at an angle of 90 degrees and are moved so that the two mutually perpendicular planes containing the line of junction of the reflecting surfaces, one of which planes is parallel to the direction of the film movement, remain at substantially constant angles to the film plane. The speed of movement of the reflecting surfaces may be such that compensation for the film movement during a flash may be effected to a limited extent; such compensation thus allows the light flashes to be slightly longer than those of the parent Specification without impairing the definition of the projected picture. In the form shown in Fig. 2, the apparatus comprises a flashing light source 16 and condenser 17 for illuminating a film 13 as it passes across the projection gate 18, the film movement during successive flashes being compensated by several roof prisms 19 mounted on a rotary disc 21; the plane containing the line of junction 23 of the orthogonal reflecting surfaces of each prism and parallel to the direction of motion of the film, remains at an angle of 45 degrees to the film plane. After two reflections at the prism the light passes through the projection lens 15 on to a screen. The projection lens may be positioned between the film and the prism to form an image in the plane of a shutter on the other side of the prism; this image may be enlarged by another lens system. In each case, the tangential speed of the prisms is arranged to be half the film speed and each prism is arranged to be operative during the projection of one film picture; the orientation of the reflecting surfaces may be maintained constant as by the means described in the parent Specification. Instead of a disc, a rotary drum may be used and the prisms are arranged thereon so that the line of junction of each pair of reflecting surfaces is parallel to the drum axis. One roof prism may be used and is displaced in the direction of the film movement a distance equal to half the frame pitch. The motion of the prism may be simple harmonic or may be such that the prism moves in the same direction as the film at a uniform speed equal to half the film speed and such as to compensate for the film movement during a flash to a limited extent and then returns quickly in the time interval between the last flash of one frame and the first flash of the next frame at a speed which compensates for the film movement between these flashes. The roof prism or prisms may be replaced by two mirrors, relatively inclined at 90 degrees, or by several pairs of such mirrors. Specification 629,179 is referred to.

Title: Means for regulating or controlling the operation of gas washers or scrubbers
IPC: B01D47/00
Filed: 1948-05-07
Abstract: 641,707. Washing gas. BUTT, F. A. May 7, 1948. No. 12563. [Class 55(ii)]' In a gas washer for reducing the ammonia content of coal gas, the admission of fresh water to the washer is controlled automatically in accordance with the density and temperature of the gas liquor. As shown, water is supplied through a valve 41, and pipe 7 to a gas washer 3, a pump 4 forcing a predetermined quantity of liquor continuously into a chamber 1 from which it overflows into a gallery 5 connected by a pipe 6 to the pipe 7. The chamber 1 contains two small bore tubes 8, 9 with enlarged upper and lower ends, the upper ends being open to form float chambers 12, 13. The tubes 8, 9 contain oil and the former is open at 14 to the liquor so that the column of oil rises as the density of the liquor increases with an increase of its ammonia content. The tube 9 and its enlarged end 11 are entirely sealed from the liquor, so that the oil level in the chamber 13 is directly determined by the temperature of the liquor. The floats 15. 16 are connected through a linkage 20, 22, 29, 25, 23 with a micro-switch 19 which is thus actuated according to the compounded effects of the density-responsive tube 8 and the temperature-responsive tube 9. The switch has contacts 32, 33, one or the other of which is in circuit in the two "on" positions of the switch. The contacts are connected to separate segments 34, 35, in a motor circuit, which are wiped by a contact 39 on the output shaft 36 of a reduction gear driven by the said motor 37. If one contact, say 34. is energized, the motor rotates until,the wiping contact 39 engages the second segment 35 and thus breaks the circuit to bring the motor to rest. The motor will remain at rest until the switch 19 is operated to energize the segment 35, whereupon the motor will rotate until the wiper touches the segment 34. The two actuations of the motor produce one revolution of the shaft 36 which carries a cam 40 for operating the valve 41 through a pivoted follower 42. The relation between the ammonia-absorption capacity of the liquor and the temperature of the liquor follows a non-linear law, and to compensate for this a curved lining 17 is provided in the float chamber 13. The tube 9 and float chamber 13 may be replaced by a bellows, aneroid or like chamber, containing oil, having mechanical connecting means for operating the linkage similarly to the float 16. Water may be supplied in normal manner to the chamber 3 from a pipe 45.
