Title: Improvements in or relating to timber connectors
IPC: E04B1/49
Filed: 1944-07-07
Abstract: 575,499. Timber connectors. STEPHENSON, P. J., and WOOD & STEEL SPECIALITIES CO., Ltd. July 7, 1944, No. 13050. [Class 89 (ii)] Timber connectors of the type comprising a ring spiked on both sides and particularly those for uniting timber and concrete have the part of the ring to be imbedded in the concrete perforated to receive the ends of bent bars c that initially lie flush with the outer surface of the ring. After imbedding in the setting concrete the bars are straightened, causing the ends to project from the rings and provide a secure anchorage. The bars may be welded where they cross. Where a bolt is imbedded for further securing the timber the bars are arranged to provide a central space to permit passage of the bolt. In a modification the bars are pivotally connected to a central frame rotation of which causes the projection.

Patent GB-838715-A (GB)
Title: Improvements in or relating to the manufacture of chromic anhydride
IPC: C01G37/033
Filed: 1957-04-24
Abstract: A crude crystal mass of chromic anhydride precipitated from a saturated alkali metal dichromate solution with concentrated sulphuric acid is separated from the associated mother liquor and at least sufficient anhydrous alkali metal sulphate is added to react with the sulphuric acid remaining in said crystal mass to form bisulphate; the mixture is fused to form two layers and the lower chromic anhydride layer separated from the upper layer of dross.  The alkali metal sulphate is preferably used in excess of the requirement and sulphuric acid may be added to the molten dross to convert the excess sulphate to bisulphate.  The alkali metal sulphate may also contain a small quantity of the corresponding chromate or dichromate. The example relates to the use of sodium as the alkali metal and involves, in the initial formation of the crude crystal mass, recycling a portion of the reaction mixture and the use of 3.5 mols. of sulphuric acid per mol. of dichromate.  After separation, the crystal mass is mixed with sodium sulphate containing 1% of sodium dichromate and heated to 190-200 DEG  C. with gentle agitation; sulphuric acid is added to the dross as mentioned above.  The lower layer is transferred to a flaking drum.  The Specification refers to a process which involves dissolving the crude crystals to form a saturated solution, precipitating chromic anhydride therefrom with sulphuric acid, separating the crystals, washing with nitric acid and heating to expel residual nitric acid, before forming the melt.

[Class 122(v)] In a metallic packing sealing arrangement for a rotating shaft 11 or sleeve 13 of the type in which a rotatable packing ring 15 is disposed between a rotatable abutment ring 17 and a non-rotatable or fixed packing ring 18, driving means is provided betveen the abutment ring 17 and the rotatable packing ring 15 and the latter is formed in at least two parts to facilitate assembly on the shaft and has in its inner face facing the shaft an annular recess 15a for soft packing 16, which recess 15a is radially inwardly open and axially closed on each side. Both the abutment ring 17 and the rotatable packing ring 15 are in halves secured by screws and the latter ring is urged toward the fixed packing ring 18 by springs 23 in axial recesses 17b in the abutment ring. Driving plates, 21 secured by screws 22 in recesses in the periphery of the abutment ring engage corresponding recesses 15b in the rotatable packing ring and thereby prevent rotary but permit axial movement between the two rings. During assembly corresponding halves of the abutment and rotatable packing rings may be held together temporarily by set screws 24 passing through clearance holes in the locking plates 21 and engaging threaded holes 15c in the periphery of the rotatable packing ririg. The sleeve 13 may be omitted and the soft packing 16 arranged to bear directly on the shaft 11. In place of the driving plates 21 a ring may be provided with axially projecting fingers secured to the abutment ring or formed integral therewith. The sealirig contact faces of the rotatable and fixed packing rings 15, 18 may be recessed to reduce the area of contact and form an oil reservoir and the contact face of the fixed packing ring may be provided on a wearing plate detachably secured thereto. The face of the fixed packing ring 18 opposite to its sealing face may be spherically sealed and engage a corresponding surface in the housing 26.

Title: Method of operating a direct gas cooler
IPC: F28C3/06
Filed: 1956-05-01
Abstract: 812,706. Contacting gases with liquids. KOPPERS G.m.b.H., H. May 1, 1956 [May 2, 1955], No. 13398/56. Class 55 (2). [Also in Group XIII] In a direct gas cooler cooling liquid flows in counter-current to the gas, is distributed over the entire cross-section of the cooler by rotating distributers 7 and is supplied to the cooler by two completely separate systems one of which transfers liquid from the bottom of the cooler through an indirect heat exchanger 15 to the middle region of the cooler while the other transfers liquid from the middle region through an indirect heat exchanger 24 to the upper part of the cooler. Liquid reaching the bottom of the cooler flows through a pipe 10 into a container 11 from which it is returned to the cooler by a pump 14 and a pipe 16. Excess liquid, such as that formed by condensation, may be removed by a pipe 13 and sprinkled on the container 11. The distributers 7, which may be discs, are rotated by a motor 6 to fling the liquid into contact with the wall 1 of the cooler where it is collected in channels 8 and returned by pipes 9 to the distributers. Liquid reaching the middle region of the cooler is withdrawn by a pipe 18 and returned by a pump 23 and a pipe 17 to the top of the cooler. If a gas containing naphthalene is to be cooled, a solvent such as tar oil, which may be extracted from the cooling water in a tar separator 19, may be supplied through a pipe 20. A hydrocarbon oil may be used in both of the coolant circulation systems if, for example, benzene hydrocarbons are to be scrubbed from coal distillation gases. The temperature of the gas, which enters the cooler at 2 and leaves at 3, may fall from 80‹ to 22‹ C. while the cooling liquid temperatures in the pipes 10, 16, 18 and 17 are 65‹, 50‹, 45‹ and 20‹C respectively, with temperatures rises from 25‹ to 45‹C and from 15‹ to 30‹C in the exchangers 15 and 24.

Title: Improvements in extrusion machines
IPC: A21C11/16
Filed: 1940-08-26
Abstract: 543,372. Extrusion machines. LOWE CORPORATION, J. Aug. 26, 1940, No. 13462. Convention date, Sept. 2, 1939. [Class 87 (ii)] An extrusion machine, particularly for forming doughnuts or like edible products, comprises a chamber 2 to which the dough batter &c. is admitted, and from which it is expelled, by air suction and pressure. An automatically opened gate valve 4 is slid sideways to admit the dough from a hopper 3, and the gravity effect is assisted by the upper part 30 of the chamber 2 being connected by a valve 25 to the suction side of a fan 44. When sufficient dough has entered the chamber the valve 4 is shut off, and the valve 25 is automatically thrown over to connect the part 30 to the pressure side of the fan 44. This forces the dough through a die built up of a tube 16 surrounded by a sliding cutter sleeve 15 and having spaced away from its open end a fixed disc 14. When the dough is being admitted to the chamber 2 the cutter 15 reaches down to contact the rim of disc 14, but when extrusion is taking place the cutter has been withdrawn and the dough comes out as an annulus which is thereupon cut off by the cutter 15 again coming down to touch the ring 14. The valves 4 and 25 of the cutter 15 are operated by levers 18, 24 and 10 from cams 19, 21 and 7 on a power shaft 9. Any number of extrusion nozzles may be fitted to the chamber 2.
