Title: Improvements in and relating to processes for continuously crystallizing sugar solutions
IPC: C13B30/02
Filed: 1935-07-26
Abstract: <PICT:0444534/III/1> Sugar solutions are continuously crystallized either by preliminarily cooling them for the formation of core grain or by addition of core grains thereto, followed by a cooling operation whereby successive amounts of heat are withdrawn from the mass which stepwise increase towards the delivery of the crystallized product, a uniform oversaturation of the mother liquor being thereby maintained.  The sugar solution flows through preliminary receptacles a, b, before flowing through coolers c, d, e in countercurrent to a stream of cooling water admitted at 7 to hollow partitions 3 arranged therein, the number of cooling surfaces in each cooler increasing towards the last.  The receptacle a is separately cooled by water admitted to the partitions at 5, the formation of core grain in the solution being initiated herein.  The formation of core grain ceases in the intervening receptacle b, which is not cooled.  The removal of increasing quantities of heat from the coolers may also be effected by tapping-off parts of the cooling fluid at 9 and 10. In a modified apparatus, the receptacles a . . . e are arranged side by side in a single unit.  The latter is also provided with a shaft and scrapers for stirring the solution.  In lieu of adding core grain to the original solution part of the cooled mass may be returned to the preliminary cooler.

Title: Improvements in and relating to the manufacture of films
Inventor: BUTEUX RICHARD HAROLD BARCLAY
IPC: B29C55/28
Filed: 1953-07-31
Abstract: Tubular film of thermoplastic material is stretched laterally by passing it through two pairs of pinch rolls, between which it is inflated, and reducing the distance between the two pairs of rolls until the desired degree of lateral stretching is obtained. Longitudinal stretching may also be effected by rotating the second pair of rolls at a higher peripheral speed than the first pair.  The film, e.g. of polyethylene terephthalate, is preferably warmed to about <PICT:0741962/IV(a)/1> 80 DEG  C.  The stretching may be carried out continuously with production or as an after-treatment. As shown, tubular film is fed through pinch rolls 2 and guide plates 3 to the heater 4, which is cylindrical with a bell-shaped mouth and may be of polished or etched metal, or of metal coated with polytetrafluorethylene or other lubricant.  The film then passes through guide plates 5 and pinch rolls 6, the plates 5 and rolls 6 being longitudinally movable.  The plates 5 may be replaced by converging pairs of bars or rollers.  Instead of the cylindrical heater 4 in contact with the film, an annular radiant heating element spaced from the film may be used.

Title: Method of turning off the display in electrochromic display devices
IPC: G02F1/153
Filed: 1977-05-20
Abstract: The display in a diffusion type electrochromic display device is turned off with high response by applying an A.C. input voltage having a frequency of one to ten times as high as the cut-off frequency. The diffusion type electrochromic display device is an EC display device which uses an EC composition consisting of an EC compound coloring in a reduced state and a solvent in which the solubility of the compound to the solvent is 10-2 mol/(100 g solvent) or more in a reduced state and 10-1 mol/(100 g solvent) or more in an oxidized state. The cut-off frequency is a critical frequency at a freqency higher than which the oxidization or reduction of the EC compound cannot follow the change in the input voltage, which is normally 20 to 50 Hz.
