Title: Improvements in wrapping machines
IPC: B65B11/42
Filed: 1929-08-08
Abstract: 341,411. Wrapping - machines. TRIGGS W. W., 57, Lincoln's Inn Fields, London.-(Package Machinery Co. ; 132, Birnie Avenue, Spring- field, Massachusetts, U.S.A.) Aug. 8, 1929, No. 24258. [Class 94 (i).] Relates. to wrapping- machines of the kind having a wrapping-wheel with oppositely disposed pockets and means whereby an article is ejected from one pocket simultaneously with the introduction of an article into the opposite pocket. According to the invention, the ejecting means is normally operated by the pressure of an article being introduced into the opposite pocket, and an associated mechanism, which is normally inoperative, becomes operative in the absence of an article in position to be fed, to operate means within the wheel to eject the previously fed article. The articles are fed on to a table 10, in front of a plunger 9 having a downwardly depending portion 25, by which they are pushed, together with a wrapper in a vertically reciprocable guide 42 into a pocket in a wrapping wheel 12. The pocket is formed by resilient plates 64, 66, Figs. 2 and 3a, and plates 70 in a movable bar 68 constituting the bottom. Normally, the movement of the bar 68 by the incoming article serves to eject the article in the opposite pocket. If, however, no article is present on the table 10, ejectors 39, Fig. 1, mounted on the plunger 9 engage rods 69 on extensions 68<1> of the bar 68 and move the latter to effect, an ejection. During the introduction of the article and wrapper, the bars 66 form a tuck b, Fig. 8, the part C being folded down by a wiper W during the subsequent intermittent rotation. During the further travel of the article, which is effected by a transporter 102, a tuck d, Fig. 9, is made by the end of a stationary folder 88, the flaps e, f are folded in by edges 90, 140, adhesive having been applied at position P<1> by mechanism 115. The transporter is caused to describe the path shown in Fig. 2b, so that the article engaging fingers 102 move forward in a horizontal path and return at a lower level.

Abstract: 773,939. Actuation switches. PAILLARD SOC. ANON. Aug. 25, 1955 [Sept. 24, 1954], No. 24461/55. Class 38(5) [Also in Group XVI] In a typewriter or like office machine, a switch mechanism coupled to the typewriter carriage, automatically cuts off supply to the typewriter driving motor at a certain time after the last carriage-return movement. The switch mechanism comprises a switch 5 moved into "on" position by a lug 12 on a control rod 8, and moved into "off" position by a lug 11 when the rod is moved rightwardly either by a knob 6 or by a lever 29 which moves slowly anti-clockwise to engage a lug 36 on the rod 8. The lever 29 is frictionally clamped on the end of a shaft 23 which carries an axially slidable sleeve 22 which has a toothed crown 26 for clutching to a similar member 27 driven through reduction gearing 28 from an electric motor 4. The sleeve 22 is pressed by a spring 24 to effect clutching between the toothed members 26, 27 and is moved against the spring by rods 39 and 20 operated from a carriage movement or a starting action respectively.  To start the machine the knob 6 is pushed to the left end of a slot 7; this operates the switch 5, and via lever mechanism 16-19 and rod 20, disconnects member 26 so that the lever 29 moves clockwise under force of a spring 33 until a finger 32 thereon is arrested by a bearing bracket 25. The knob 6 now returns to a position 14, leaves the switch 5 "on", but members 26, 27 engage to drive the lever 29 slowly anti-clockwise until it engages the lug 36 to effect a switching-off movement. At each, carriage return movement however, the rod 39 is operated by mechanism 37, 38, 40-42 to disengage the member 26. 27 so that the lever again flies back to the position shown by the force of the spring 33.

Title: Improvements in and relating to the separation of primary and tertiary nitrogen bases from mixtures thereof
Filed: 1945-09-21
Abstract: Aniline is recovered from mixtures containing it and tertiary cyclic nitrogen bases, e.g., pyridines, by distilling such mixtures, e.g., coal tar bases, in presence of a paraffin fraction so that the aniline is distilled off in the form of an aniline-paraffin azeotropic mixture while the tertiary bases are separated as a higher boiling fraction or residue.  The aniline is then separated from the paraffins (a) by fractional distillation in the presence of water (b) by distilling off the aniline-paraffin azeotropic mixture to leave residual aniline (c) by washing the mixture with acid and recovering the aniline as aniline salt.  75 gallons of coal tar bases distilling 5 per cent. at 184 DEG C. and 95 per cent. at 189 DEG C. and 25 gallons of a paraffin mixture distilling 5 per cent. at 181 DEG C. and 95 per cent. at 199 DEG C. were charged into a still with fractionating column, condenser and separator arranged to return the top layer separated to the still and take off the bottom layer.  The mixture was distilled with a column top temperature of from 165 to 172 DEG C. 40 gallons of product obtained showed a content of 7 per cent. paraffins which were removed as an azeotrope with aniline by further distillation to 184 DEG C. the receiver being then changed and the residual aniline collected.  The azeotrope condensate was utilised for treating a further batch.

Title: Process for the production of water or hydrogen having an increased deuterium content
IPC: B01D59/32
Filed: 1955-08-26
Abstract: <PICT:0803274/III/1> Water or hydrogen having an increased deuterium content is produced by passing liquid water successively through two columns maintained at different temperatures, while hydrogen is passed successively through the two columns in countercurrent to the water, in deuterium-exchanging relation therewith, in the presence of a catalyst under elevated pressure.  The catalyst may be fixed as packing, or coating thereon, as a net, or as a lining to the column, but is preferably circulated as a dispersion or colloidal sol in the liquid water, or as a precipitate on a suspended carrier, e.g. active carbon.  Suitable catalysts are platinum, palladium or nickel.  The catalyst dispersion, or sol, or liquid water may include wetting agents, or substances to regulate or reduce pH.  Hydrogen of normal deuterium content enters at 23 hot column 22, which is at above 150 DEG  C., preferably at 200 DEG  C., and passes, preferably via heat-exchanger 31, to cold column 21, which is at below 100 DEG  C., preferably at 20-50 DEG  C.  The catalyst sol is continuously circulated by pump 30 into column 21 at 27, through heat exchanger 32, column 22, and heat exchanger 32.  The columns may be packed, e.g. with glass coils, and the pressure is at least 10 atmos., preferably 100 atmos., H2 of increased D content, may be withdrawn at 24 or 25, or water of increased D content may be obtained by withdrawing catalyst sol at 28, and removing catalyst therefrom. Corresponding further quantities of catalyst sol may be added to replace that withdrawn, or a corresponding amount of liquid water may be condensed by cooling the gas from the top of column 22, and this water may be withdrawn at 24, or from heat exchanger 31.  The circulating catalyst may be regenerated by introducing into the circuit, e.g. at 77, cartridges containing ion exchangers, or other substances combining with poisons, the exhausted cartridges being extracted and replaced during operation.  The stability of the catalyst sol may be increased by ultrasonic treatment, e.g. at 77. Alternatively, a smll portion of catalyst suspension may be withdrawn and replaced as required.  In Fig. 2 (not shown), the H2 and catalyst sol are both circulated in closed cycle through the hot and cold columns, and an auxiliary column, filled with active packing, is included in the H2 circuit through which water of normal, or higher, D content is passed at 200 DEG  C. in closed, or open, circuit, counter-current to the H2, which is thus enriched with D.  In Fig. 3 (not shown) a number of series-connected stages each of a hot and cold column are provided coupled through the liquid or gas phase, or through water of condensation.
