Title: Improvements in or relating to the electrodialysis apparatus
IPC: B01D61/50
Filed: 1960-02-09
Abstract: A multi-compartment electrodialysis apparatus according to the parent Specification is modified in that not all the intermediate plates A, B, interrupt the continuity of the internal electrolyte conduits. Each internal conduit comprises a plurality of parallel conduits formed by cooperating holes 13-16 in adjacent membranes and intervening gaskets, the gaskets having suitably arranged slots leading from the holes to the compartments to ensure the required supply and removal of liquid to and from alternate compartments, Fig. 11 (not shown). A support, e.g. of perforated, corrugated, plastic material, is located in each compartment.  The holes 13-16 also occur in each plate A, B, and may be blind or through holes.  If blind, they are spaced along transverse conduits 131-161 in the plate, these conduits being open at one or both ends and connected to an external pipe 2131-2161.  If the holes 13-16 are through holes, at least one supply and withdrawal pipe 2131-2161 is provided at each pair of adjacent plates A. B.  The separate rinsing compartment in the plates A, B and the separate liquid connections 27, 271, 28, 281 thereto are retained, but are not shown in Fig. 1, and the rinsing compartments contain a grid, Fig. 5 (not shown).  The end electrodes, and intermediate electrodes if provided, are mounted in frames similar to the plates A, B, except that the holes corresponding to 13-16 are not connected to the internal electrolyte conduits, but communicate with <PICT:0948915/C3/1> <PICT:0948915/C3/2> transverse ducts in the frames for the supply and removal of rinsing liquid to and from each face of the electrodes.  The electrodes comprise a plurality of abutting graphite plates secured by graphite bosses to the sides of the electrode frames. End electrodes are separated from the rest of the apparatus by a plate A or B, and intermediate electrodes are sandwiched between plates A, B, membranes intervening.  The plates A, B and the electrode frames are of beech wood impregnated with phenolformaldehyde containing 50-68% solids.  The apparatus is suspended from hooks engaging holes 105 in the plates A, B which have rollers running on rails extending the length of the apparatus.ALSO:Insulating material for electrodialytic cells (see Division C7) is made by subjecting European or English beech to a vacuum of within 1 or 2 inches of mercury of absolute vacuum for 2 to 3 hours and then impregnating with an unpolymerized phenolformaldehyde resin solution containing 50% to 68% solids by weight at a pressure of 80 pounds per square inch gauge for 12 to 24 hours.  After drying, the wood is heat cured for four days at at least 200 DEG F.

Title: Improvements in darning mechanism
IPC: D04B17/00
Filed: 1931-02-16
Abstract: 370,571. Darning mechanism. GIBBES, A. E., Gowing's Buildings, Market Street, Sydney, Australia. Feb. 16, 1931, No. 4842. [Class 112.] An ordinary sewing machine is provided with a carriage having a step-by-step transversely reciprocated frame for carrying the material to be darned, and a spiral spring attachment 12 instead of the presser foot. The step-bystep motion of the carriage longitudinally of the machine is effected by a manually operated worm. The usual feed mechanism is also dispensed with. The carriage 16 is supported on a guide-plate 14 and guided by a rail 15. The carriage carries a shaft 17 sliding in brackets 18, 19. A rack bar 20 is also secured to the carriage and is engaged by a pinion 22. A worm pinion 23 is mounted on the same shaft as the pinion 22. Normally the pinion 23 is engaged by the worm 25 and is intermittently rotated by the lever 27 which is returned to normal position by the spring 30. A leafspring 31 engages a square 32 on the end of the shaft 26. To allow the carriage to be moved freely, the shaft 26 is lowered by moving the lever 33 thereby disengaging the worm 25 from the pinion 23. The carriage is then moved bv the crank handle 34. The work is placed in the usual darning frame which is held by the arms 36 of the holder 35 detachably secured to the carriage by the screw 39. This holder is carried on the rack bar 37, Fig. 4, arranged in the carriage 16. This bar is engaged by a pinion 40 capable of being raised in its bearings by a hand lever 41 and adapted to engage a worm 42 keyed to the shaft 38. When raised, the pinion 40 remains in engagement with the rack bar 37, but is disengaged from the driving worm 42. The shaft 38 is coupled to a flexible driving shaft 43 whose other end is coupled to a spindle 44, Fig. 2, to bring wheels 47, 48 alternatively into engagement with a driving pinion 49 driven by the electric motor 52 which drives the machine. Reciprocation of the spindle 44 is effected by a lever 55, which is oscillated by a cam by depression of the hand lever 27. To facilitate the repair of stockings with V-shaped heel parts, a triangular graph 59 is used with a pointer 60 attached to the holder 35.

Title: Improvements in apparatus for following up a target moving relatively to the spot at which the apparatus is mounted
IPC: F41G5/00
Filed: 1931-02-17
Abstract: 371,517. Sighting and following moving targets. NAAMLOOZE VENNOOTSCHAP NEDERLANDSCHE INSTRUMENTENCOMPAGNIE, 44, Javastraat, The Hague. Feb. 17, 1931, No. 4973. Convention date, Feb. 25, 1930. [Class 92 (ii).] Apparatus for sighting and automatically following a moving target, for the purpose of determining its linear or angular velocity and acceleration, comprises a hand-operated gear 7, Fig. 1, which controls the sighting telescope 28 through one side-wheel 14 of a differential gear 13, 14, 15 the other side-wheel 15 of which is driven by a constant-speed motor 2 through a variable-speed device 1, 3, the adjustable member 3 of which is connected with the hand-gear 7. In the form shown in Fig. 1, the pivoted sight-arm 29 is moved by a screw 25 rotated from the wheel 14 by the planetary member 18 of a second differential gear 17, 18, 20, the side-wheel 20 of which may be driven by a hand-gear 23 for initial adjustment of the sight on to the target. In following up a target moving with uniform velocity, the handgear 7 is operated, the member 3 being set by a screw 5 and the drive being taken over by the motor 2 when the operator ceases to turn the hand-gear 7. To obviate further adjustments to the hand-gear 7 if the target accelerates, a further variable-speed gear 48, 49, Fig. 2, driven by a motor 2 is added, the adjustable member 51 of which is set by a hand-wheel 53 so that the motor then conveys the additional movement to the hand-gear 7. Scales 34, 65 enable the velocity and acceleration of the target to be read off. In a modification, the motion of the hand-wheel 7 causes a mark on the screw 5 to move, and a similar mark on an adjacent screw is kept in register with the first mark by adjusting the variable-speed gear member 51. In a further modification, a ruler operated by the member 51 is kept tangential to a velocity curve plotted on a continuously rotating drum by a marker moving with the member 6. The gearing used to drive the telescope 28 may operate the valve of a hydraulic variable-speed device which itself drives the telescope.

Title: Process for isolating acetylene and carbon dioxide from cracked gases
IPC: C10K1/16
Filed: 1969-01-30
Abstract: 1,242,634. Separating carbon dioxide and acetylene from cracked gas. FARBWERKE HOECHST A.G. 30 Jan., 1969 [30 Jan., 1968], No. 5208/69. Heading B1L. Carbon dioxide and acetylene are separated from cracked gas streams which also contain other hydrocarbons, hydrogen, water and carbon monoxide by passing the stream by line 1 to acetone wash column 2 having a sump temperature of -10 to -50‹C. and a head temperature of -25 to -60‹C at 10-20 atmos. abs. Gaseous overhead leaves the process, while liquid sorbate passes by line 3 to fractional absorber-desorber 4 at 2-6 atmos. abs., the column having a sump temperature of -20 to 20‹C., and a fractionating column temperature of -20 to -60‹C, wherein the desorbed gases are washed with acetone supplied by line 5 until the desorbed gases contain 10-20 mol % CO 2  and the reabsorbed gases contain at most 0.2 mol % C 2 H 4 . The gaseous overhead from column 4 is returned to feed line 1, while the acetone solution bottoms are passed to desorber 6 and released to a pressure of 1-55 atmos, abs. and a temperature preferably of 105-115‹C. while at the same time being washed with anhydrous acetone which enters through line 17 and which removes water. Wet acetone bottoms containing hydrocarbons passes by line 15 for rectification in column 14. Gaseous overhead from desorber 6 passes by line 7 through drying towers 18 containing silica gel, activated carbon, or molecular sieves to wash column 8 where, at a pressure of 1.6-2 atmos. abs. and a head temperature of -15 to -25‹C. C 2 H 2  is absorbed in a wash stream of dimethyl formamide leaving an overhead of CO 2 . The sorbate passes by line 9 to column 10, where C 2 H 2  is stripped as the overhead, and the dimethyl formamide bottoms returned as wash liquid to column 8. In an alternative embodiment (see Fig. 2, not shown), the gaseous overhead from desorber 6 passes by line 7 to the base of dimethyl formamide absorber (11), bottoms therefrom passing to rectifying absorber (12), CO 2  being collected as the overheads from absorbers (11) and (12). Bottoms from absorber (12) pass to desorber (13) which releases an overhead of C 2 H 2  and a bottom product of dimethyl formamide which is returned to absorbers (11) and (12).

Title: A machine for pressing, smoothing or embossing leather
IPC: C14B1/00
Filed: 1957-02-18
Abstract: 809,179. Leather-rolling machines. MASCHINENFABRIK MOENUS A.G. Feb. 18, 1957 [Feb. 18, 1956; May 19, 1956 ; Dec. 20, 1956], No. 5428/57. Class 76. [Also in Groups XVI and XXXII] In a machine for smoothing leather, wherein a carriage bearing a revoluble and upwardlypressed pressure roller is moved to and fro on rails to press the leather against a pressure plate, the carriage is self-propelled by a power unit thereon driving its running wheels. Uprights 2, 3 of the machine frame carry two rails 4, 5 on each of which run two wheels 24 of the carriage 6. The wheels 24 are keyed to axles 7, 8 which are journalled in bearings in intermediate and end walls 17, 18 of the carriage. Also keyed to the axle 8 are pinions 27, Fig. 3, which engage racks 25 fitted to the rails 4, 5, and a worm wheel 13. A worm 14 engages the worm wheel 13 and is driven by an electric motor 9 mounted on the carriage, thus causing the axle 8, wheels 24 and pinions 27 to rotate and the carriage to move along the rails 4, 5. Abutments 10, 11 at each end of the rails operate reversing switches so that the carriage moves to and fro between them. The pressure roller 21 is spring mounted in the top of the carriage 6 and is driven, e.g. by a bevel gear arrangement 22, from the axle 7, in the opposite direction to the wheels 24. The leather is held against the underside of the pressure plate 19<SP>1</SP> of a heated pressure chest 19, which is covered by a sheet of felt or leather, by a table not shown in the drawing, and is embossed by the roller 21 which presses up against it. Ramps 30 are disposed at each end of the pressure chest 19 to avoid shock when the roller 21 runs on to the leather on the pressure plate 19<SP>1</SP>. Each ramp 30 has a shoe 34, Fig. 5, attached to two plates 33 which depend from the eccentric end portions 32 of a shaft 31 journalled in slots 30<SP>1</SP> in the ramp walls. The shaft 31 has a flat extension 35 at one end to which a handle 36 having a forked part 37 is pivoted by means of a pin 41 so that by swing- ing the handle on its pivot away from the machine the forked part 37 presses on the adjacent plate 33 and both plates are drawn toward each other and clamped against the walls of the ramp 30 when the handle 36 is at a right angle thereto. To accommodate varying thicknesses of pressure plate the shoe 34 is raised or lowered by the eccentrics 32 when the handle 36 is turned and a wedge is slidable laterally, by means of a screw 38, between the shoe and the body of the ramp so that no gap is left therebetween. The shoe 34 is also adjustable laterally by moving the shaft 31 along the slots 30<SP>1</SP>. Dished springs threaded on bolts may be used to support the roller 21 (see Group XXXII), the lower springs being thinner than the upper ones so that the first pressure is gentle and yielding.
