Method for assembling a modular support structure of an item-processing machine comprising hubs for bearing respective shafts of moving members, and a plurality of link elements fixable at hubs, the method including: a) providing a toleranced jig plate with means defining the definitive boss position of hubs, b) providing fixing portions integral with hubs or fixing portions integral with link elements, fixing portions defining a volume for receiving in loose engagement a respective fixing portion and fillable with a curable resin, c) arranging hubs at their defined boss positions, d) arranging link elements in loose engagement with hubs to form a temporary skeleton, and e) permanently fixing link elements to respective fixing portions of hubs via injection and hardening of a curable resin.
摘要:
The invention relates to a method for applying a label to an article travelling along an article path, said label being received on a movable surface at an input location to be retained against said surface whilst being glued and advanced to an output location, at which the label is transferred to the article; the article being rotated with a tangential speed about an axis whilst travelling at a speed along the path including providing at least three portions of surface with independent and controllable vacuum means for retaining the label, including curtailing the application of vacuum means at the first portion of the surface upon the first portion reaching the output location and interrupting the application of vacuum means at the third portion of the surface, with the trailing edge of the label being retained at the second portion of the surface.

There is disclosed a container processing machine comprising a material handling surface for handling a sheet-like material through suction and a vacuum source in fluid connection with said material handling surface, the machine including means for detecting and transmitting a value of pressure of the gas being suctioned; a controllably operable flow valve; a control unit operatively connected with said detection and transmission means and with said flow valve; said detection and transmission means and said flow valve being arranged between said vacuum source and said material handling surface; said control unit being programmed to adjust the degree of opening of said flow valve in response to a signal which is a function of at least said value of pressure.
摘要:
A process for treating effluents, such as precious metal tailings, having a pH of at least 9 and containing cyanide is described in which Caro's acid is added to the effluent having a pH of at least 9 and commencing the reaction of the cyanide with Caro's acid at 0.degree. C. to 80.degree. C. in the absence of an added alkali; adding sufficient Caro's acid within a mole ratio of Caro's acid to cyanide of 0.3/1 to 3/1 to reduce the pH of the effluent to below 9, continuing the reaction between Caro's acid and the cyanide to reduce the amount of cyanide remaining in the effluent and to recover an environmentally compatible effluent reduced in amounts of cyanide.

This invention relates to a process for producing Caro's acid by reaction of at least 85% by weight sulfuric acid and at least 50% by weight hydrogen peroxide wherein the sulfuric acid and hydrogen peroxide are fed through separate feed lines into a funneling zone open to the atmosphere, the feed lines having air gaps between their ends and the funneling zone; continuing to introduce the sulfuric acid and the hydrogen peroxide into the funneling zone to flow and mix within the funneling zone, passing the resulting mixture by gravity flow into one end of a reaction zone whose size permits a pressure drop which is at least 8 times the theoretical pressure drop for such reaction zone and removing a mixture containing Caro's acid from the exit end of the reaction zone.

An apparatus (1) for conveying containers (2) with non circular cross section, comprising at least two input conveyors, a re-uniting star-wheel (5), on which the two distinct conveyance flows are re-united, an auxiliary star-wheel (6) cooperating with said re-uniting star-wheel (5), first engaging means (50) mounted on the re-uniting star-wheel (5) and acting on containers housed in corresponding pits of the auxiliary star-wheel (6) to keep them correctly oriented into said pits before they are transferred on the reuniting star-wheel (5) and second engaging means (60) mounted on the auxiliary star-wheel (6) and acting on containers housed in corresponding pits of the reuniting star-wheel (5) to keep them correctly oriented into said pits during the rotation of the re-uniting star-wheel (5). Said first and second engaging means (50, 60) are active when the containers (2) reach said merging area.
