Abstract: 1,092,384. Machine tool details. VEEDER INDUSTRIES Inc. Feb. 8, 1965 [April 27, 1964], No. 5443/65. Headings B3B and B3T. A device for transferring elongated workpiece A from a chuck 2 to a chuck 4 in a lathe and then removing the workpiece from chuck 4, the workpiece being turned end for end before insertion in chuck 4, comprises an oscillating work transfer finger 20, and a work removing finger 56. Finger 20 has work gripping means 22, Fig. 7, and is axially movable within a tubular shaft 26, fixed to a horizontal shaft 32. A cam 34, Fig. 1B co-operates with a bell crank lever 36, which through a connecting rod 38 and lever 72, Fig. 6, oscillates shaft 32 so that means 22 moves in an arcuate path between the chucks. Shaft 26 carries a pinion 42 which co-operates with a gear segment 43, so that as the finger oscillates, it also rotates through 180 degrees, so that workpiece A is turned end for end. A pair of tappets 44, 46, Fig. 1B, are mounted on a shaft 48 which is oscillated by a cam 35 through a bell crank lever 50 and a connecting rod 52. The tappets engage the end 24 of finger 20 when it is adjacent a chuck, and moves it against a spring 28 into alignment with the chuck, whereupon the workpiece is moved out of chuck 2 into the finger, or out of the finger into chuck 4. Gripping means 22 comprises elements pivoted at 23, Fig. 7, end urged together to grip the work by a spring urged ball 27. Finger 56 is mounted with a pin-and-slot connection 58, 60, Fig. 1B, to a hollow shaft 62 which is connected to a shaft 64. At one end of finger 56 is a work discharge tube 66 having a slot 68 therein. Shaft 64 is connected to shaft 32 by a rod 70, Fig. 6, and finger 56 oscillates in tandem with finger 20. A tappet 76 carried by shaft 48 or connected to tappet 46 moves finger 56 towards chuck 4 at the required moment so that the work can be removed from the collet. In a modification, tube 66 is replaced by a pan 82, Fig. 8, carried by shaft 60 so that when the shaft is oscillated the pan tilts about a shaft 78 and discharges the work. In operation, workpieces A are fed along guide rails 10, Fig. 1A, are picked up by fingers 12, turned through approximately 90 degrees, and aligned with chuck 2. An operation is carried out by a tool 6, and the workpiece is ejected from collet 2 into finger 20 which is urged downwardly by tappet 46, Fig. 6. Spring 28 moves the work and finger upwardly, the work is then moved in an arcuate path and turned end for end, and tappet 44 moves it into alignment with chuck 4. A rod forces the workpieces into chuck 4, and a second operation is carried out by tool 8, Fig. 1A. Finger 20 is returned to the first collet, and the cycle is repeated with finger 56 removing the workpiece from chuck 4.

IPC: C10C1/04
Filed: 1953-02-27
Abstract: In a process for the recovery of pyridine from crude tars and oils containing pyridine bases by continuous distillation of the tar &c. and separation of the distillate into aqueous and non-aqueous portions, the latter is treated to remove its pyridine content and is then returned to the distillation as reflux, thus lowering the content of pyridine in the aqueous portion.  The pyridine is removed from the oily layer by washing with sulphuric acid.  Distillate from a plant (not shown) passes to an automatic separator A from which the top oily layer flows to a stripping column C packed with rings and filled with sulphuric acid.  The pyridine sulphate passes to a storage tank and the stripped oil to a settling tank D and control tank E and thence to reflux tank F from which it is returned to the distillation plant.ALSO:In a process for the recovery of pyridine from crude tars and oils containing pyridine bases by continuous distillation of the tar, &c., and separation of the distillate into aqueous and non-aqueous portions, the latter is treated to remove its pyridine content and is then returned to the distillation as reflux thus lowering the content of pyridine in the aqueous portion.

Title: Method and apparatus for developing electrostatic images with electroscopic powder
Inventor: WALKUP LEWIS EDMUND
IPC: G03G15/30
Filed: 1950-03-06
Abstract: 693,905. Producing photographs electrically. BATTELLE DEVELOPMENT CORPORATION. March 6, 1950, No. 5565/50. Class 98 (ii). [Also in Group XVI] An electrostatically charged image-wise insulating layer supported on a conductive plate is developed by applying an electrostaticallycharged powder to the layer and simultaneously inducing on the non-insulated area of the plate, by applying an electrostatic field across its thickness, a charge having a polarity opposite to that of the charge on the layer and the same as the charge on the developing powder to repel powder from the non-insulated areas. Preferably the powder is applied between the plate and an adjacent electrode between which the electrostatic field is produced, the potential applied to the electrode being of the same polarity as that of the charge on the layer. As shown, an image-wise insulating layer on a conducting plate 2 on a drum 1 is charged by means of discharge points 13 and, if desired, additional points 15,16, and electrostatic-image developing powder is poured from a store 3 on to the plate to the charged areas of which it adheres, the surplus falling into a receiver 5. Concentric with the drum over the powder-applying region is a part-cylindrical electrode 17 which is held at a potential of the same sign as the charge on the insulating layer on the plate 2, a charge of opposite sign being induced on the uncoated areas of the plate. When a developer powder, comprising an electroscopic powder and a granular carrier which generate opposite triboelectric charges on each other, is fed to the drum, the electroscopic powder having a charge opposite to that on the insulating layer, the uncoated parts of the plate repel the powder which is thus retained only imagewise. The powder image is then transferred to a paper strip 6 fed round the drum by means of a corona discharge from the point 13, whereafter the paper is peeled from the drum by fingers 8, and passed over heaters 12 which fuse the electroscopic powder to the paper, the record so produced being finally wound up at 11. Excess powder remaining on the plate after the transfer is removed by any suitable means 14. Specifications 658,699, 675,398 and 679,715 are referred to.
