Patent FI-20106079-A (FI)
Inventor: BERG CARL-GUSTAV
IPC: B01D47/06
Filed: 2010-10-18
Abstract: A method and assembly for separating contaminants from liquids, such as condensates, or vapors at an evaporation plant. The contaminants are separated from liquids by stripping when bringing a contaminant-enriched liquid into direct contact with a vapor by spraying or distributing the liquid into the vapor flowing in a vapor duct or onto wall surfaces in the vapor duct thus reducing the contaminant-content of the sprayed liquid and producing a cleaner liquid. The contaminants are enriched in the vapor. From vapors contaminants are separated by absorption when bringing a contaminant-enriched vapor into direct contact with a cleaner liquid by spraying or distributing the liquid into the vapor flowing in a vapor duct or onto wall surfaces in the vapor duct thus increasing the contaminant-content of the liquid, but producing a cleaned vapor.

Sheets of paper or cardboard which have been punched in a press 1, 2 are fed through the press and delivered therefrom by gripper bars 4 on endless chains 3 which are driven intermittently, and are further delivered to a waste ejecting or other means 8, 10 by a first and second rotary delivery means at a different horizontal level. The chains 3, which are arranged one at each side of the press 1, 2, are stationary in the punching position shown, and are then accelerated to deliver the sheet 5 at maximum speed to a first rotary means comprising discs 11, 12, the discs 11 being gapped at 13 to allow passage of the gripper bar 4. When the discs grip the sheet, they do so at the same peripheral speed as the sheet and bar 4, and at the same horizontal level; thereafter, the peripheral speed of the discs is decreased, and the arcs of the discs are lowered so that the sheet 5 is guided by a series of supports 14 towards a second rotary means comprising discs 15, 16 which rotate at a constant peripheral speed, the discs 16 being gapped at 17 to allow the bar 4 to pass. The sheet 5 is fed to rollers 6, 7, and by them to a waste ejecting means comprising drums 8, 10, the periphery of the drum 8 having needles &c. 9 for engaging with the sheet waste. The discs 11 perform at least two revolutions during the passage therethrough of two successive bars 4. In the constructional drawings, Figs. 7-14 (not shown), the discs 11, 12 are derated, respectively, 18, 19, and the discs 18 are carried in a pivoted frame 31 on which is pivoted a second frame 34 carrying the discs 19, whereby both sets of discs can first be lowered together, and subsequent lowering separates the frames 31, 34 and the discs. A satellite gearing couplings Figs. 7 and 8, including gears 58, 59 of different diameters, and cam-actuated means, causes acceleration and retardation of the discs 18, 19.

An easel for a photographic enlarger has a base with a first carriage displaceable in one direction thereon, and a second carriage displaceable in a transverse direction on said first carriage. In the form shown, the lower carriage 7 can move on the base plate 1 as guided by rollers 8 and 9 running on rails 5, 6. The top surface of carriage 7 has rails 12, 13 such that the upper carriage 18 is guided thereby for movement transverse to that of carriage 7. On the upper carriage is a support 19 for the photosensitive sheet, which can thus be displaced in all directions. Pivoted at 21, 22 to carriage 18 is a flat bridge 20 carrying a lever 23, and normally urged by a blade spring 25 into contact with a brake block 29. The brake block is carried by a braking claw 27 which is fixed to a blade spring 28 attached to the lower carriage 7, Fig. 8 (not shown). The lower part of claw 27 has two rubber lining pieces which bear against the inside of a U-shaped member 26 secured to the base plate 1. Thus normally the braking claw 27 exerts a braking action against both lower and upper carriages, holding them both in fixed position. Pressure on knob 24 releases both braking actions simultaneously, so that both carriages are then free to move.
