Title: Improvements relating to the Proving of Dough.
IPC: A21C13/02
Filed: 1917-01-10
Abstract: 110,996. Baker & Sons, J., Kirman, H., and Taroni, C. E. Jan. 10, 1917. Proving or raising appliances. - In order to vary the time of proving dough in the manufacture of bread, biscuits, &c., the dough portions are deposited at various places in the length of a horizontal or slightly inclined constant-speed conveyer in the proving-chamber. Fig. 1 shows diagrammatically a conveyer 7a in a proving-chamber 9. The dough portions are fed from a hopper 1 and a " hander-up " 2 to a shoot with branches 3, 4 and a valve which allows the dough to pass by the shoot 3 to the extreme end of the conveyer 7<a>, or by the shoot 4 to an extensible conveyer consisting of two telescoping sections 10, 11. A fast-running web 13 passes over end rollers 14, 15, intermediate rollers 16, 17 on the sections 11, 10 respectively, and a tensioning-roller 19. The conveyer is adjusted so that the inner end of the web deposits the dough through one of the shoots 24, 25 in the length of the conveyer 7a, and thus shortens as desired the time of proving. In modifications, the telescoping-section conveyer is replaced by a number of small endless-band conveyers in tandem, all of which, except the first, are arranged so that they may be lifted about their forward ends, and thus cause the dough to drop off the forward end of the last horizontal conveyer on to the prover conveyer 7a. The spaces between the ends of these small conveyers are filled by pairs of small rollers. A gear wheel on the spindle at the rear end of each small conveyer drives the next conveyer through an idle wheel.

Patent GB-909136-A (GB)
Title: A process for the manufacture of anhydrous hydrofluoric acid from its aqueous solutions
IPC: C01B7/19
Filed: 1959-01-06
Abstract: Anhydrous hydrofluoric acid is prepared from aqueous solutions thereof by a process comprising mixing concentrated sulphuric acid with the solution, heating the mixture to a temperature so that at least part of the HF distils off, contacting the resulting residue of dilute sulphuric acid containing HF with a current of gas chemically inert to HF whereupon the gas becomes charged with HF, and bringing the HF-charged gas into contact with the concentrated sulphuric acid before the latter is mixed with the aqueous solution.  Whereupon the HF passes completely into the p  concentrated sulphuric acid.  An aqueous solution of HF, and concentrated H2SO4, are containuously introduced into a vessel 3 provided with an agitator 7 and heating jacket 8, through pumps 1 and 4 from reservoirs 2 and 5 respectively, the concentrated H2SO4 also passing through a packed column 6 before entering vessel <PICT:0909136/III/1> 3. The mixture in vessel 3 is heated, preferably to about 120 DEG C. by heating fluid circulating in jacket 8 and anhydrous HF distils off and is collected in the upper part of rectifying column 9 from where it is subsequently passed to condenser 12 where it condenses in coils 13 and is finally collected in reservoir 14. The rates of feed of concentrated H2SO4 and aqueous solution to the vessel 3 are preferably regulated so that, taking into account the respective concentration of the H2SO4 and aqueous solution, the mixture collecting in vessel 3 after the anhydrous HF has been distilled off is about 75% by wt. H2SO4.  The dilute H2SO4/HF mixture remaining in vessel 3 flows under gravity down the overflow pipe 10 and down tower 11 packed with silica-free refractory packing, e.g. coke or graphite Raschig rings, in countercurrent to a rising stream of air introduced into the tower at 15, and which leaves at 16 charged with HF vapour, the residual diluted H2SO4 running from the bottom of the tower to be collected in reservoir 17.  The air charged with HF vapour passes from tower 11 to the foot of packed column 6 up which it passes in countercurrent to the descending stream of concentrated H2SO4 entering vessel 3.  Air entirely free from HF escapes through 18, whilst concentrated H2SO4 containing the entire HF introduced into the column by the air stream passes into vessel 3 to complete the cycle.

Title: Process for continuous freezing concentration of solutions
IPC: A23L2/12
Filed: 1973-01-04
Abstract: 1407305 Concentrating solutions KRAUSSMAFFEI AG 4 Jan 1973 [1 Feb 1972] 624/73 Heading B1G Solutions are freeze concentrated by subdividing the solution into two parts, cooling one part until it is solid and breaking down the solid to fine granules, cooling the second part to the freezing point of the solution or just a little above, mixing with agitation the two parts until the granules have dissolved, separating off e.g. by centrifuging, the solvent crystals formed and recovering the solution concentrated. If desired the solution to be concentrated may be cooled to the freezing point or just above before division. As shown in the flow diagram, in heat exchanger 1, the solution is cooled only to the temperature where non-crystallization of solvent occurs. Part of this solution is further cooled on a cooling roller 2 until it is solidified after which it is comminuted to fine granules. In mixing device 3, the granulated particles and precooled solution are mixed until the particles dissolve. During dissolution, crystals of pure solvent form and these are separated from the solution in centrifuge 4, and the concentrate removed via pipe 5. The solvent crystals are removed through pipe 6 and conveyed by pipe 8 to device 3 where they function as seed crystals. Alternatively the crystals may be conveyed via pipe 7 to the centrifuge 4, where in the melted state they are used as a wash liquid. In two other modifications not shown the above arrangement is in one case combined with a similar arrangement and in the other case with another type of scraping cooler crystallizer for further concentrating the solution. The specification also includes a flow diagram, which includes temperatures and concentrations, for concentrating citrus juice.
