Title: Hydrogen ion concentration adjustment
IPC: B01J19/00
Filed: 1950-02-09
Abstract: 692,568. Automatic control systems. ROBICHAUX, R. P. Feb. 9, 1950 [Feb. 10, 1949; Dec. 22, 1949], No. 3341/50. Class 38 (iv). [Also in Group I] In the adjustment of the hydrogen ion concentration of a flowable material, the material is caused to flow at a constant rate, and a pH- correction medium is automatically introduced, while the material is under vacuum, whenever the pH value deviates from an established magnitude. With the apparatus of Figs. 1 and 2, milk is pumped into a distributing head 7 in a vacuum chamber 5 and is there mixed with steam; from the chamber 5 the milk flows into a chamber 11 in which is a pressure lower than in the chamber 5, from the chamber 11 is introduced tangentially into a chamber 17, in which is a pressure lower than in the chamber 11, to swirl down over the inner wall of the chamber 17, and is pumped from the chamber 17 by way of a conduit 21 to a cooler 22. From the conduit 21 is a by-pass pipe 31 to which the flow of milk is regulated by a valve 32; milk flowing into the pipe 31 passes through a chamber 331 in which is an assembly of a measuring electrode, a reference electrode, and a temperature compensator; the assembly is connected to a potentiometer 34, the pH of the milk at the operating temperature being measured on the scale 34<SP>1</SP> of the potentiometer. Upon deviation of the pH from the control value, a controller 37, which is connected electrically to the potentiometer 34, causes operation of a motor 39 (Fig. 1) to open a valve 30 and allow pH-correction medium to pass from a vessel 27 thereof, along a pipe 29, into the chamber 17; alternatively (Fig. 2), deviation of pH from the control valve in one direction brings about delivery of an appropriate pH- correction medium from one of the vessels 27<SP>1</SP>, and deviation of pH in the other direction brings about delivery from the other of the vessels 27<SP>1</SP> of a different pH-correction medium. Specifications 413,460, 418,591 and 538,755, [all in Group VI], and U.S.A. Specification 2,378,425 are referred to.

Abstract: 371,495. Type-printing telegraphy. WESTOVER, G., ELLIOTT, R. C., and MONOTYPE CORPORATION, Ltd., 43, Fetter Lane, London. Feb. 3, 1931, No. 3406. [Class 40 (iii).] Machines, such as that described in Specification 17199/08, [Class 100, Printing, Letterpress &c.], for perforating record-strips for controlling type-casting machines are adapted for the telegraphic transmission of typographic matter by causing the punch-operating bars or the valve-controlling bars of the punchmotors to operate circuit-closers, which transmit different impulses to a receiving station, where one or more record-strips for controlling automatic type-casting machines are produced. The valve-controlling bars B<6>, Fig. 1, which are operated through permutation mechanism from key-levers B, act as stops to prevent the rotation of circuit-closers in the form of contact-making discs A, which are frictionally mounted on rotating shafts A<2>. Each disc has a stud A<6>, Fig. 3, which, in passing between one or more pairs of jaws A<5> as the disc rotates, completes successively the circuits of one or more solenoids D, Fig. 4. Contacts D<16> are thereby attracted, and close gaps in a main transmitting circuit, so that one or more impulses are sent through a single main transmitting cable D<36> to the distant station, or a separate cable may be used for each impulse. The discs A are arrested after one revolution. The discs are arranged on two series of sixteen, since each signal usually consists of two perforations, to effect movement of the die-case of the casting-machine in two directions at right-angles. The number of circuits and the width of the record-strip may be reduced by the use of a permutation system, in which each complete signal may comprise from one to four components from each of two series. Specifications 23297/09, 197,996, and 217,773, [all in Class 100 (iii), Type-making &c.], also are referred to.
