Title: Method and arrangmeent for agitating and controlling the temperature of baths, particularly melts for heat treating metallic articles
Inventor: BOECKENHOFF HERMANN-JOSEF
IPC: B01D5/00
Filed: 1975-07-17
Granted: 1978-10-17
Abstract: ABSTRACT OF THE DISCLOSURE         A fluid is admitted into a bath having a certain temper-ature.  The temperature of the fluid is different from that of the bath.  The fluid travels through the bath so that heat trans-fer occurs between the bath and the fluid while, at the same time, the bath is thus caused to be agitated.  The flow of the fluid into the bath is regulated in such a manner as to maintain the temperature of the bath within predetermined limits.  A preferred application resides in the cooling of a bath, particularly one which is used for the heat treatment of steel wire which has been hot rolled immediately prior to the introduction thereof into the bath.  Here, the fluid may be in the form of a gas upon being admitted into the bath.  Alternatively, the fluid may be in the form of a liquid which vaporizes at the temperature of the bath,  In this event, heat is removed from the bath partially in the form of the heat of vaporization of the liquid.  It is also possible to feed both a gas and a liquid into the bath.  In this manner, a cooling effect may be obtained which is less than that if only a vaporizable liquid were used without, however, incurring a loss in the degree of agitation of the bath.

Abstract: PROCESS FOR THE MANUFACTURE OF PRESSED PEAT SUBSTRATES        ABSTRACT OF THE DISCLOSURE    In order to produce pressed peat substrate, it is first necessary to obtain a peat substrate with a moisture content of 93 to 97 percent. To this end, the peaty mass is wetted with an aqueous solution of calcitic materials, inorganic fertilizers and trace elements. The resultant substrate is pressed and dried at a temperature in the range from 40 to 105°C. to an average moisture content through the bulk of the pressed peat substrate of at least 15 percent.      The proposed process produces pressed peat substrates which are sturdy enough to protect the root system of plants in the course of transportation and replanting, at the same presenting no soil pollution problem such as exists with prior art substrates which use synthetic materials to help main-tain a specified shape of the substrates. The pressed peat substrate manufactured in accordance with the proposed process may be produced as blocks of individual planting cells having a geometrically regular and stable shape, which makes the pro-cesses of utilization of the pressed blocks readily mechani-zable.

Abstract: ABSTRACT OF THE DISCLOSURE         An improvement is provided in a conventional electrolytic chromating procedure.  A steel sheet is first subjected to a cathodic electrolytic chromate treatment in an electrolytic chromating bath, at a relatively high speed of 400 to 1,000m per minute, to form substantially simultaneously, a lower layer of metallic chromium and an upper layer of hydrated chromium oxides on the surface of said steel sheet, in which the initial amount of the hydrated chromium oxide layer exceeds 0.4 mg/dm2  expressed as chromium, and the amount of the hydrated chromium oxide layer is then adjusted within a desired range.  The improvement comprises the steps of subjecting a steel sheet to a cathodic electrolytic chromate treatment at a relatively high speed of 400 to 1,000m per minute in a conventional electrolytic chromating bath, to form substantially simultaneously, a lower layer of metallic chromium and an upper layer of hydrated chromium oxides on the surface of said steel sheet; and then, subjecting said electrolytically chromated steel sheet to an anodic electrolytic treatment under the following conditions in said electrolytic chromating bath, to adjust the amount of said hydrated chromium oxide layer within the range from 0.1 to 0.3 mg/dm2, expressed as chromium:          Bath temperature   : room temp. - 70°C, Anodic current density   : 0.5 - 8A/dm2, Treating time            : 0.5 - 2 sec., Amount of electricity    : 1 - 8 Coulomb/dm2.          By this procedure, the thickness of the hydrated chromium oxide layer may be adjusted at will.
