Abstract: 1409927 Concentrating #-1,3-glucan suspensions TAKEDA YAKUHIN KOGYO KK 16 Oct 1973 [16 Oct 1972 20 Nov 1972] 48125/73 Heading C3U A process for concentrating a suspension of a thermally gelable polysaccharide composed predominantly of #-1,3-glucan comprises dissolving a water-soluble salt of calcium, magnesium or zinc in an amount of 0.03 to 0.75 mol./1. in a suspension of the polysaccharide; making the suspension alkaline so as to dissolve the suspended polysaccharide; adding an acid to the resulting solution to precipitate the polysaccharide; and finally separating and recovering the polysaccharide. In a preliminary treatment the starting suspension may be purified prior to the above concentration by adjusting the pH of the suspension to above 12 to dissolve suspended polysaccharide; adding thereto 0.03 to 0.2 mole/litre relative to each 1% by weight/ volume of the polysaccharide present, of calcium chloride, or calcium hydroxide to lower the viscosity of the polysaccharide solution; removing the insoluble contaminants therefrom; and adding thereto an acid to regain a suspension of the polysaccharide.

Purified water is obtained from saline water by feeding the saline water into reservoir 34 which distributes it into channels 18 formed by vertical plates 16 closely aligned side by side, the upper ends of the plates forming orifices 19 below the water-level in the reservoir and the lower surfaces of the plates being tapered so as to provide outward flaring of the channels 18 in the downward direction whereby smooth flash vaporization takes place from the saline water which flows down the channels and forms liquid films of the lower surfaces of the plates 16; the steam which is evolved condenses on condenser 26, and the purified water is withdrawn through outlet 28. The plates 16 are preferably made of wood or other hygroscopic material. The saline water to be treated is heated to about 102F. and introduced through inlet 36 into deaeration chamber 32 which is maintained at a pressure of about 2 psia by pump 39. The degasified saline water flows from chamber 32 into the reservoir 34 whence the water passes through orifices 19 and flows down the widening channels between the plates. The unevaporated brine runs off the bottoms of the plates down fins 22 and collects in troughs 24, from which it is discharged. The outer surfaces of the troughs define diffusion cones 25 through which the steam evolved in channels 18 flows to the condenser chamber 20, where the pressure is about 0.8 psia. Residual air is withdrawn from the condenser chamber via vent 29.

It is further indicated that the auxiliary loop circuits or overflow links 64 (Fig. 2) of the system are only resorted to under blocking conditions for certain categories of calls, e.g. transfer calls and conference calls. All other features are generally as described in the main Specification. Line circuit: (Fig. 5).-A transformer 320 provides the coupling between the balanced speech line 301, 302 and the unbalanced wire 324 connected to the switching matrix, wires 305 and 306 being ringing and bias wires. In operation a loop detector 310 of the type disclosed in Specification 1,150,594 enables gate 314 which produces an output on wire 382 when the line circuit is next scanned to give an indication of the calling condition. A central processing unit causes the wire 324 to be marked via gate 354, bi-stable 352 and transistor 360 for path setting up purposes. The subscriber is rung by the enabling of gate 362 by the central processing unit to operate bi-stable 384 and relay 370, the contacts 372, 374 of which cause the application of ringing current to the subscriber station. Call transfer and conferences: (Fig. 2).-It is assumed that an internal subscriber at station 1 is connected to an external trunk via a path A. To effect a transfer to another internal subscriber, e.g. station 2, a hook switch signal is given at station 1 to cause the external trunk to be held and the path A to be dropped. The station 1 subscriber dials station 2 and paths C, D and E are established and station 2 is rung. Station 1 and station 2 are connected by paths C and D and the external trunk remains on hold. By means of a second hook switch signal at station 1 a connection is also established via path E to the external trunk and a three way conference takes place. To effect a call transfer station 1 hangs up. Paths C, D and E are dropped and the system attempts to set up a direct path F between station 2 and the external trunk. If all such paths are blocked a search is made for a free auxiliary loop circuit 64 and a path such as G, H is established.

Abstract: 1,098,339. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 23, 1966 [Dec. 4, 1965], No. 52425/66. Addition to 1,035,089. Heading H1K. The masking method of Specification 1,035,089 (in which narrow apertures are formed in a masking coating by cracks produced by differential thermal expansion) is applied to the manufacture of semi-conductor components in which impurity-doped regions are required to be separated by narrow undoped regions. Such components are manufactured by incorporating a suitable dopant in the coating and subsequently diffusing this dopant into the underlying semi-conductor. The undoped areas beneath the cracks in the coating may subsequently be doped by diffusion through the cracks, or have more semi-conductor material or an electrode material applied to them by deposition through the cracks. The drawings (not shown) depict the use of this technique to produce: a lateral transistor consisting of two side-by-side N-doped areas separated by a narrow gap in a P-type semiconductor body; an insulated gate field effect transistor; and a PN uni-junction transistor. The applicability of the invention to integrated circuits is also mentioned. The described embodiments are of gallium arsenide doped with zinc or tin by diffusion from a cracked masking coating of silicon dioxide. The coating is formed by thermal dissociation of specified organic compounds of silicon and the doping substance. The doped oxide is deposited from the vapour phase to a thickness of 5000 or more A and subsequently cracked by the technique described in the parent Specification, the coating being mechanically grooved at the sites where cracking is required before heating to produce the cracks.
