Abstract: 545,767. Ammonium salts from flue gases, sulphurs. FRANCIS, W., SIMON - CARVES Ltd., and FULHAM, MAYOR, ALDERMEN AND COUNCILLORS OF THE METROPOLITAN BOROUGH OF. Dec. 6, 1940, No. 17385. [Classes 1 (ii) and 90] Flue gases are treated to remove sulphur compounds by a closed cycle method including introduction of ammoniacal scrubbing liquor into the hot gases, e.g. as a spray, before they enter the scrubber proper so as to concentrate the scrubbing liquor, a purge of the scrubbing liquor being taken from the closed cycle equivalent to the production of fixed ammonium salts, and means being provided for testing the exit gases from the scrubber by ascertaining the pH value of water through which the gases are bubbled whereby to determine the rate of addition of ammoniacal scrubbing liquor to maintain the said pH value at a desired level'. The ammoniacal scrubbing liquor may contain loosely combined ammonia as hydrate, carbonate and sulphide. Liquor in the scrubber proper is obtained from previous cycles and is substantially neutral. The products from the purge consist essentially of ammonium sulphate and sulphite ; the solution is passed to an autoclave and heated with sulphuric acid at about 12 atmospheres pressure, with addition of a relatively small proportion of sulphur to keep the reaction under control. Depending on the amount of sulphuric acid added, ammonium sulphide alone or ammonium sulphate and sulphur are obtained. Specification 360,574 is referred to.

Title: Improvements in the treatment of foodstuffs by cooking
IPC: A47J37/12
Filed: 1944-09-15
Abstract: 587,690. Cooking apparatus. SPOONER, W. W. Sept. 15, 1944, No. 17646. [Class 28 (i)] Foodstuffs such as sliced potatoes, doughnuts, or fish, are cooked on a reticular support or conveyer 26, immersed in cooking liquid 25, such as syrup, oil or molten fat, the cooking liquid being heated by streams of hot air or gases from nozzles 35 impinging on to the surface of the liquid. The heat applied to the liquid through which the foodstuff is passed continuously or intermittently is proportional to the heat taken up by the foodstuffs. In operation, the lid 18 of a closed cooking chamber 17 is hinged up and the food is placed on the higher first run 26 of the endless conveyer. A link 38 attached to the lid turns a ratchet wheel 41 counter-clockwise, so that a stop 42 allows a switch 31 to close the circuit to resistance heaters 44, and also starts up a fan 32 which pumps air through the heaters and the nozzles 35 on to the cooking liquid 25. When the liquid attains a sufficient temperature, a thermostatic switch 43 starts the electric motor 29 which starts moving the endlessconveyer 20-26. The motor 29 also turns slowly the friction disc 44, carrying the stop 42 counter-clockwise, so that when the food has travelled from '26 to the discharge chute 27, the stop 42 will break all circuits at the switch 31. If a further batch of food is placed on the higher run 26 of the conveyer, while a previous batch is still being cooked on the immersed run 26, the lifting of the lid 18 to insert the batch also turns the ratchet wheel so that the stop 42 is delayed in its action of opening the switch 31 to disconnect all the circuits. The machine therefore may operate continuously when food is being continuodsly placed on the higher run 26, or will only operate for such time as is necessary to cook an individual batch placed on the conveyer. The fan also withdraws the air in the chamber through an exhaust port 36. Cooked food arriving at the discharge chute 27 swings open the gravity closed door 28, to allow the food to proceed down the chute. The cooking liquid 25 may be additionally heated by steam coils or gas burners or by a further series of hot air nozzles under the liquid bath. Specification 587,691 is referred to.

Multiple bolt fastenings; sliding bolts; locks, squarekey.-A double-door fastening of the kind wherein a spindle actuates a pair of vertical bolts and a horizontal bolt, is constructed so that the initial rotation of the spindle operates the horizontal bolt and further rotation operates the vertical bolts so that one door can be opened while the other remains secured. The operating spindle 6 is turned by a square key and has three cranks 8 with two opposed studs 9 which work in slots 16 in the vertical bolts 13. A stud 25 works in a broad-arrow-shaped slot 22 in the horizontal bolt and also co-operates with holes 26, 27, 28 in the casing. Figs. 1 and 3 show the bolts shot. To withdraw them the spindle 6 is first pushed inwards against a blade spring 10 to free the stud 25 from the hole 28, and turned. The stud 25 engages the inclined side of the slot 24 in the bolt 19 and withdraws it. If the key is then removed, the spring 10 forces the stud 25 into the hole 27 of the casing so that the bolts are locked in the position in which the horizontal bolt is withdrawn, allowing one door to open and the vertical bolts are shot, securing the other door. Further turning of the spindle past this point causes the studs 9 to withdraw the bolts 13, the stud 25 entering the hole 26 to secure all the bolts in the withdrawn position. The bolt 19 has flanges 20 to limit its degree of protrusion.
