Title: Process for purifying beet sugar waste
IPC: C13B35/08
Filed: 1959-09-17
Abstract: 883,922. Purifying waste sugar solutions. AJINOMOTO CO. Inc. Sept. 17, 1959 [July 24, 1959], No. 31740/59. Class 127. [Also in Group XXXVI] In purifying beet sugar waste solutions, e.g. Steffen's waste, vinasse, to obtain a pure solution of pyroglutamic acid from which glutamic acid may be crystallized after hydrolysis, the waste solution is first concentrated to a pyroglutamic acid content exceeding 3%, by weight, and subjected to electrodialysis through an anion exchange membrane, impurities, e.g. other organic acids, inoragnic ions, passing through the membrane. The residual pyroglutamic acid solution is then diluted to a pyroglutamic acid content of less than 3%, by weight adjusted to a pH between 3 and 7, and again electrodialysed, the pyroglutamic acid being electrophorized through the membrane leaving behind amino acids and neutral substances If desired the second stage may be performed first In Fig. 1, the concentrated waste solution is introduced into compartments 2, 4 and electrolyte e.g. dilute aqueous sodium sulphate solution, into compartments 3, 5, and into the cathode and anode compartments 1 and n, respectively, at such a rate that extreme acid or alkaline conditions at the electrodes are avoided; anion and cation exchange membranes A and C respectively separate the compartments. In the second stage the partly purified pyroglutamic acid solution remaining in the compartments 2, 4 (Fig. 1) is diluted, adjusted in pH and introduced into compartments 2, 4 of the apparatus shown in Fig. 2, the other compartments 3, 5, 1 and n being filled with electrolyte as in the first stage. The pyroglutamic acid is then electrophorized into compartments 3, 5 and the purified solution removed therefrom, hydrolysed, and crystallized. In another embodiment both stages are effected in a single, slightly modified, apparatus.

Classes 40 (5) and 40 (7) An aerial system which is based on the introduction of magnetic discontinuity into the transmission medium comprises an extensive conducting surface having disposed therein or mounted closely adjacent thereto a magnetic antenna element formed of an elongated body of high frequency, high permeability material, such as a dust-iron or ferrite bar, which is associated with signal coupling means. The system is. of particular application to aircraft where, as shown in section in Fig. 3, the magnetic element 12 may be retained by low-loss plastic 13 in a depression in the air-foil 11. Fig. 2 illutrates an embodiment arranged for direction finding in which three such elements 12 are arranged in the surface 11 as shown and coupled to a disc 15 of similar magnetic material disposed in a circular opening 14. The disc is rotatable to establish the direction of arrival of radio waves and carries a coil 16 from which connections extend'via slip rings, Fig. 4 (not shown). The elements carry shaped pole pieces 20 which are adjustable to reduce sextantal error, and the angular position of the elements may also be adjusted to compensate for quadrantal error. Fig. 1 (not shown) illustrates an embodiment comprising a single magnetic element carrying a coil and located in a slot in a conductive sheet. Aerials according to the invention are suitable for operation at any frequency including low frequencies; the direction finder illustrated in Fig. 2, when constructed with elements 14 inches long, operates in the range 100- 1750 kc.

Abstract: 813,069. Bending glass sheets. LIBBEYOWENS-FORD GLASS CO. Oct. 22, 1956 [March 27, 1956], No. 32031/56. Class 56. In the bending of glass sheets to form curved windscreens having side wing portions and a top cap portion that merges into the vehicle roof, the sheet(s) 45 is/are initially supported above the three-part concave mould 24 with one longitudinal edge continuously supported by pads 48 and the other longitudinal edge supported by pads 53, Fig. 5, only near its ends. The supports of both sets of pads are mechanically linked to the wing portions 30 of the mould. As the mould traverses the bending lehr, different parts of the glass sheet(s) are subjected to different degrees of heating by differential heating of the lehr and by the position and shape of screens 55, 59. The softening of the glass and the closing action of the mould wings first cause the centre of the glass edge supported only at 53 to sag on to the middle of the mould edge 31 and then, as this glass edge progressively sinks to take the shape of edge 31, the pads 48 supporting the other edge of the glass are lowered so that this edge now contacts and takes the shape of the other mould edge member 32 and the cap line V, Fig. 15, is formed.

Apparatus for classifying an analogue input signal into one of a number of classes includes a comparator 26 which compares the analogue input signal with a comparison signal which is successively discretely increased or decreased until the signals are equal when one of a plurality of counter 60-65 is incremented. In the embodiment described the comparison signals are generated by a switch 30-35 being stepped by control logic 29 to successively switch in resistors 40-45 until the comparison signal is equal to an analogue current representing the input voltage V 1 . Switches 5O-55 controlling counter 60-65 respectively are enabled synchronously with switches 30-35 so that when the polarity of the signal from comparator 26 changes the control logic 29 applies a pulse on line 66 to all the counters, the counter enabled by the closed switch being incremented by one. The counts may be used for a histogram display such as that of Specification 1,166,387.
