Abstract: 1487567 Lock GKN-STENMAN AB 12 Dec 1974 53867/74 Heading E2A A lock of the type requiring a complete revolution of an appropriate. key to bring the lock to a fully locked conditionhas a bolt 2, at least one lock cylinder, at least one operating means which is rotatable by said lock cylinder or cylinders and is arranged to displace an operating member 7 between two limit positions during at least part of. a  rotation of the operating means, the arrangement being such that the operating means can enter into or move out of engagement with the operating member 7 when said operating member is in either of the limit positions, a toothed rack 7a on the operating member 7, a pivotally mounted arm member 8 associated with the bolt 2, the arm member being pivotable at 9 to displace the bolt, via linkage, between a locking position and a release position, the arm member 8 having a toothed segment 8a engaging with the toothed rack 7a so that displacement of the operating member 7 causes pivoting of the arm member 8, a link 16, 17 co-operating with the arm member 8 and defining therewith a toggle linkage arranged to move overcentre during displacement of the bolt between the locking and release positions, and a spring arranged to bias said toggle linkage towards the mutually oppositely cranked conditions thereof on either side of the straight or centre condition.  In an embodiment lock cylinders 5, 5' are actuated by operating means comprising followers 6, 6' in bearings 4, 4' respectively. Projections 6a, 6'a of the followers 6, 6' can be received in a recess 7b in the operating member 7 when the latter is in either of its limit positions. Thus either lock cylinder 5 or 5' can displace the member 7 by a partrotation of a key (not shown) so as to move the bolt 2 to its locked position as shown in Fig. 1 or to its released position as shown in Fig. 3. The followers 6, 6' are each provided with a recess for engagement by a spring 20 which is supported at 21 and ensures that the followers are positioned so as to allow the insertion or removal of the key (not shown).

Abstract: 1,255,290. Cigarettes. BRITISH-AMERICAN TOBACCO CO. Ltd. 13 Nov., 1970 [19 Jan., 1970], No. 54147/70. Heading A2C. [Also in Division D2] A cigarette has a wrapper that has been modified by treatment with a burn accelerating agent in a preselected area, the amount of the agent being greater closest to the butt end and lesser nearer the tip end of the cigarette, so that the preselected area burns in advance of the advancing cigarette coal to allow air to enter during smoking in an amount that increases as the burning coal more closely approaches the butt end of the cigarette. The agent is preferably sodium chlorate, but other suitable materials are sodium bromate, potassium chlorate, alkali and alkaline earth metal perchlorates, sodium nitrite, potassium nitrite, ammonium perchlorate, and nitric acid. The agent may be applied to the wrapper in the form of parallel rectangular strips interrupted along their lengths in the axial direction of the cigarette, or in the forms of spaced circular or semi-circular rings, an interrupted helical band, printed letters, or a substantially checkerboard pattern. The treated areas either increase in area or number, are more closely spaced, or are more heavily treated, towards the butt end of the cigarette. The agent may be applied in aqueous solution to the wrapper either by means of a felt pad before or after wrapping the cigarette, or by gravure printing before wrapping. A dye may be included in the treatment solution to render the treated areas visible. The areas not treated with the accelerating agent may be treated with a burn retarding agent.

Abstract: 1,210,528. Recording apparatus. PERKIN-ELMER CORP. Nov. 29, 1967 [Dec. 5, 1966], No. 54333/67. Heading G1J. A chart recorder comprises a carriage 12 movable in a first direction, a recording member 26 carried by and movable in relation to the carriage in a second coplanar perpendicular direction and a cable 40 secured to both the carriage and the recording member. The cable, which is secured to the carriage by a screw 124 and to the recording member by a screw 126, is arranged so that the carriage drive 100 only imports movement to the carriage 12. The recording member is driven by a motor 80 on the shaft 64 of which is mounted a pair of cable reservoirs 60- 78 over which the cable is wound so that movement is imported to the part of the cable secured to the recording member but not to the part secured to the carriage. Each reservoir includes a pulley 76 or 78 freely rotatable about a shaft 72 or 74 respectively. The shafts are mounted on a pulley block 70 secured to the shaft 64 on which two large pulleys 60, 62 are freely mounted. Rotation of the shaft 64 and consequently of the block 70 causes rotation of the pulleys 76, 78 about their axes 72, 74 as well as about the shaft 64. Due to this rotation of the pulleys 76, 78, the cable, which is also wound over the pulleys 60, 62 and tensioned by a spring 125, moves the recording member 26 only. The recording member slides on parallel bars.22, 24 secured to blocks 14, 16 which ride on tracks 18, 20. As shown, the recorder is used with a stationary chart but a continuous strip chart may be moved under the recording member.

A solution or suspension of a polymer in an organic liquid is converted with a liquid immiscible therewith into an unstable coarse dispersion in which the immiscible liquid forms the continuous phase, and the resulting dispersion is introduced through a nozzle into the bottom of a vessel containing a liquid which is also immiscible with the polymer solution or dispersion and whose temperature is higher than that at which the organic solvent boils, the rate at which the dispersion flows from the nozzle into the immiscible liquid and the rate at which the organic solvent volatilizes being regulated by a steam jet guided annularly around the liquid stream issuing from the nozzle. The immiscible liquid is preferably water in each case. The invention is particularly applicable to separating a carbon tetrachloride solution of chlorinated rubber containing soda as acid acceptor, a toluene solution of polybutadiene and chlorinated polyethylene from carbon tetrachloride.
