June 26, 1933, Nos. 30462 /34 and 36073 /34. Convention dates, June 27, 1932 and Aug. 12, 1932. Divided out of 421,603. [Classes 39 (i) and 40 (iii)] Distortion due to current between a cathoderay and deflecting - plates is eliminated by energizing the deflecting-plates in opposite phase. Oscillations from a relaxation-oscillation generator of line-change frequency are applied to an amplifier 8, which supplies a deflecting-potential to a terminal 12 of one deflecting-plate. From an anode resistance 13 control potential is applied to a second amplifier 18, which supplies a deflecting- potential of equal frequency and amplitude, but reverse phase to a terminal 24 of the other deflecting-plate. The amplitude of the deflecting-potential is regulated by a potentiometer 7 in the input to the amplifier. The leads 10, 20 carrying the deflecting-potentials are bridged by a high-resistance potentiometer 28 with an earthed tapping 29, which is shifted to vary the relative bias of the deflecting-plates and hence the position of the image. A negative bias of at least 500 volts relative to the anode is applied to the deflecting plates through a terminal 27. The second pair of deflecting-plates have a section curved about the mean position of the ray, Fig. 7 (not shown).

Title: Improvements in processes of recovering sulphur dioxide from waste gases
IPC: C01B17/60
Filed: 1936-11-11
Abstract: In recovering sulphur dioxide from gases by cyclicly contacting the gases with a cold aqueous solution containing a sulphite and a bisulphite and thereafter heating the said solution, the heating is effected in the presence of a liquid organic acid which is only slightly soluble in the cold solution but whose solubility increases rapidly with increase in temperature, the liquid acid not being substantially present as a second liquid phase with the cold aqueous solution when it contacts with the gases.  Suitable acids are n-butyric, n-valeric or n-caproic acids, or their isomers, or mixtures thereof.  Waste gases containing sulphur dioxide are introduced into a scrubber 5 through a pipe 6, the sulphur dioxide being absorbed by a solution of ammonium sulphite and bisulphite introduced through a distributer 9.  The sulphur dioxide-free gas passes <PICT:0484714/III/1> through baffles 10 to an exit pipe 12. The scrubber is provided with a cooling coil 7.  The charged solution passes through a pipe 13, a heat exchanger 14 and a pre-heater 15 to a regenerator chamber 18, being mixed on its way with liquid organic acid supplied through a pipe 30 to the connection 32.  The regenerator is provided with a heater 20.  The regenerated solution passes through the heat-exchanger 14 and a cooler 24 to a trap 28. The liquid acid separates from the solution owing to cooling and is removed by means of the trap 28 for recirculation into the pipe 30 while the aqueous phase is returned through a pipe 29 to the scrubber 5.  The sulphur dioxide evolved in the regenerator 18 is washed free from ammonia in a scrubber 33, is cooled in a cooler 38 and is freed from condensed water in a separating chamber 36. The condensed water is returned by a pipe 19 in part to the bottom of the regenerator and in part to the scrubber 33.  The ammonia containing liquor from the scrubber passes through a pipe 40 to the bottom of the regenerator. U.S.A. Specification 1,908,731 and German Specification 553,910 are referred to.  The Specification as open to inspection under Sect. 91 comprises also the application of the process to the recovery of other acidic gases such as carbon dioxide and hydrogen sulphide. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,071,018. Packages. H. H. BLUMER. July 23, 1965 [July 31, 1964], No. 31411/65. Heading B8C. A package of a stack of flat articles comprises a non-adhesive tape 1 extending around three sides of the stack and a pressure sensitive adhesive tape 2 extending across the other side, the end portions (la), (2a) being joined together. The end portion (la) of non-adhesive paper or cellulose acetate tape, Fig. 1 (not shown), is turned back at (1b) and overlied by the end of the pressure sensitive adhesive tape (2a) which overlies the adjacent single layer of the non-adhesive tape. A like construction occurs at the bottom face of the package. A stack S of sheets &c. to be packaged, is placed on a ram 23 and against a guide 11, which is adjustable with respect to a fixed guide 8. The adhesive tape 2 is joined to the non-adhesive tape 1 initially manually and then by the previous packaging operation as later described. The ram 23 travels upwards over support rollers 22, bringing the stack S into contact with the tapes, until it abuts a stop 28. The halting of the ram 23 stops the unwinding of the tape 2, Fig. 5 (not shown). Just prior to the halting of the ram 23 a pin 26 engages a pawl 49 to release a second ram 33 which travels perpendicularly to the ram 23, by lifting a tooth 49a out of engagement with a tooth 50a on the second ram. A clamping face 40a on the ram 33 pinches the tape 1, which passes through slots 33, 35, 39 in the ram, against a member (51), Fig. 6 (not shown). When the second ram 33 advances further, a screw 70 on the machine frame trips a lever 44 on the ram and releases a knife which moves forward under spring bias along the second ram and severs the tape 1. The knife advances further and severs the tape 2 against a movable clamping block 52 the projecting portions of the ram pinching the tapes together at two positions on either side of the knife.

Catches 69a on leaf springs 69 on the ram 33 engage spring bars 53 on the movable block 52. The drive is then reversed and both rams begin to move back to their original position, the clamps 69a on the ram 33 pulling the clamping block 52 with the ram to fold the tape portions extending around the stack underneath the latter and forming an identical joint between the portions extending from the reels 7, 36, the adhesive tape adhering to the portion (1b) of the non-adhesive tape 1, Fig. 8 (not shown). Upon further backward movement of the ram 33, the block 52 is halted by the member 51 whereupon the clamps 69a are released, the spring bars 53 returning the block 52 to its original position. The taped stack S in the guides 8, 11 is ejected by the next stack passing through the machine and may fall into a shoot or on to a conveyer.
