Abstract: 486,832. Solidifying liquids by cooling. CES. FUR LINDE'S EISMASCHINEN AKT.- GES., and KRAUSE, G. A. Aug. 27, 1937, No. 23526. Convention date, Sept. 25, 1936. [Class 29] In a process for concentrating aqueous solutions, e.g. fruit juices, milk, and meat extracts, by freezing out a part of the water and subsequently separating the ice from the solution, the freezing is effected at progressively diminishing temperatures. The temperature may be reduced in steps or continuously. Thus, orange juice having a 45 per cent concentration of dry or solid substance may be converted into a solution having a concentration of 60 per cent by pouring the solution into an annular cell, as described in Specification 429,474, and immersing the cell first in a brine bath having a temperature of about - 14‹ C., then in a bath at a temperature of - 20‹ C. and finally in one at a temperature of - 26‹ C. The freezing temperature may be reduced at a rate proportional to the fall in the ice precipitation temperature due to increasing-concentration.

Abstract: 1,269,366. Casting machines. BUHLER A.G. GEB. 8 May, 1969 [9 May, 1968], No. 23595/69. Heading B3F. [Also in Division G3] In a moulding press a first mould part is moved towards a second mould part by a toggle mechanism acting between the first mould part and a datum member, the force applied to the toggle being compared with a desired force so that any difference automatically controls the position of the datum member to restore the desired force. As applied to a pressure casting machine, Fig. 2, one mould half 21 is fixed to a member 2 which is movable along rods 4 relative to the other half 11, by an hydraulic ram 32 operating through toggle mechanism 30 to move member 2 relative to a member 3. As the ram operates to close the mould, a cam 22 is moved until it is between switches 41, 43 where a comparison is made between the force applied to the ram, as detected by a fluid-pressure sensor 33 and a desired pressure. If the pressure is outside predetermined limits, the sense of the deviation is stored. Then, when the mould is released and cam 22 reaches a switch 40 at the point of separation, a motor 50 is operated automatically for a period which is either fixed in the one arrangement, or dependent on the magnitude of the deviation in the other, to adjust nuts 61 engaging screwed sections of rods 4 so that the position of member 3 is adjusted relative to the rods to restore the pressure to a tolerable value. Sprocket drives between motor 50 and nuts 61 may be conically clamped to the nuts to permit release and adjustment of the nuts relative to their drive with the aid of scales and pointers thereon. A counter may respond to the number of substantially successive pressure reducing corrections so that, if the number is excessive due to the effect of moulding flashes, an alarm is sounded and/or the press stopped. If the pressure is dangerously high or low an alarm is sounded. Provision is made for manual control of motor 50. Use of transistors and photoelectric, capacitive or inductive position detectors is referred to.
