Title: Improvements in or relating to the removal of hydrocyanic acid from coal distillation gases
IPC: C10K1/00
Filed: 1953-08-06
Abstract: 744,333. Purifying coal gas. BERGWERKSVERBAND ZUR VERWERTUNG VON SCHUTZRECHTEN DER KOHLENTECHNIK GES. Aug. 6, 1953 [Aug. 8, 1952], No. 21775/53. Class 55 (2). Hydrocyanic acid and the last traces of tar are removed from coal gas after. it has been cooled and substantially freed from tar and before it is scrubbed for removal of H 2 S and NH 3 , by dry purification preferably using a sulphided mass containing iron, e.g. bog iron ore or the spent material which has been used for the removal of the last traces of H 2 S, without adding oxygen, or, preferably, hydrated iron oxide containing alkali. If trivalent Fe is present this must first be reduced and, together with bivalent Fe, sulphided before reaction with HCN and the NH 3  present to give (NH 4 ) 4  Fe(CN) 6 . The HCN also combines with S and NH 3  to give NH 4 CNS. After the removal of the HCN and last traces of tar in dry purifier 6, the desulphurization and removal of NH 3  may be carried out at an elevated pressure, after the gas has been cooled at 9, in scrubbers 10, 11 or a NH 3  remover may be interposed before a compressor 8 or, alternatively, the scrubbing may be carried out at atmospherical pressure. When purifier 6 has been recharged with unsulphided material its role is exchanged with that of purifier , 7 in which the sulphidation takes place, the sulphided material in purifier 7 being used for HCN removal at 6. Purifier 7 may be omitted if sulphided material from purifier 12 is used in 6 or if the incomplete removal of HCN during the first stages of the sulphidation which will then take place in purifier 6 can be permitted. The degree of enrichment of.the mass with HCN depends to a great extent on its state of division, its water content which should initially be about 40 per cent, and where the quantity of NH 3  is less than 1 gram per cubic metre irrigation of the mass with NH 3  water is advantageous. The removal of NH 3  in scrubber 11 may take place after the removal of the last traces of H 2 S in one or more purifiers 12. Saturators charged with dilute H 2 SO 4  may replace the NH 3  scrubbers.

Abstract: 654,199. Reflex photographic cameras. WORSSELL, St. J. M. Aug. 26, 1948, No. 22525. [Class 98 (i)] A reflex camera having a rotary disc provided with two diametrically opposite sectorial apertures arranged in front of the reflex, viewing mirror and the camera exposure aperture is provided with means for tensioning the shutter disc driving spring, the shutter being disposed so as to open the exposure aperture to the viewing mirror, and when the shutter release is operated the shutter disc is first rotated through 90 degrees to close the aperture, after which the viewing mirror is raised and the shutter disc then rotated in the same direction through a further 180 degrees to make an exposure. As shown, a shutter disc comprising sectors C<SP>1</SP>, C<SP>2</SP> is secured to a spindle D in front of the reflex viewing mirror B and exposure aperture A but behind the camera lens (not shown). The shutter is set by turning an external knob G<SP>5</SP> which through gearing G<SP>4</SP>... G<SP>1</SP> tensions a spring F which is connected between the spindle D and the gear G<SP>1</SP> freely mounted thereon. When the shutter is set the shutter disc opening C<SP>4</SP> is opposite the viewing mirror and a lug J<SP>1</SP> on the housing H for the spring F carried by the spindle D is engaged by an arm K secured to a shaft L and urged anticlockwise by a spring N. On initially depressing the manually-operable release trigger M, also carried by the shaft L, the arm K clears the lug J<SP>1</SP> and moves into the path of a second lug J<SP>2</SP> so that the spindle D and shutter disc rotate anticlockwise through 90 degrees as seen in Fig. 1, under the action of spring F to close the aperture A, while on further depression of the arm M the arm K rides along the face of the lug J<SP>2</SP> and simultaneously a third arm O on the shaft L engages a pin P on a link Q<SP>2</SP> supported on a pivoted arm Q3 and connected to an arm Q<SP>1</SP> fixed to the pivot S of the mirror B so as to raise the mirror against its spring T. Finally the arm K clears the lug J<SP>2</SP> and moves into the path of a lug J<SP>3</SP> thereby permitting the shutter disc to rotate anticlockwise through a further 180 degrees to make an exposure. Release of the trigger M allows the spring T to return the mirror B to the viewing position and moves the arm K out of the path of the lug J<SP>3</SP> and into the path of lug J<SP>1</SP> so that the shutter and spindle D rotate another 90 degrees to the initial position. A sector C<SP>5</SP>, coaxial with the shutter, is angularly adjustable to vary the size of the exposure-making sector gap C<SP>3</SP> of shutter disc, by being secured to a sleeve C<SP>6</SP> rotatable on the spindle D and controlled by the engagement in a slot C<SP>7</SP> therein of a pin C' on an axially movable member C<SP>9</SP> yoked to a manually-operable lever U.
