Title: Improvements relating to the treatment of ferrous sulphate
Inventor: REEVE LEWIS
IPC: C01G49/06
Filed: 1960-08-08
Abstract: Ferrous sulphate in aqueous solution is treated with calcium chloride to form calcium sulphate and ferrous chloride, the resultant ferrous chloride is hydrolysed to iron oxide and the hydrogen chloride produced during the hydrolysis is caused to react with limestone or chalk to yield calcium chloride, and this chloride is used to treat further ferrous sulphate.  The calcium sulphite is separated from the ferrous chloride solution by filtration and the ferrous chloride is converted to solid form and hydrolysed by a mixture of steam and oxygen at a temperature of from 300-350 DEG  C.  The ferrous chloride may, however, be dried and hydrolysed in a single step by being sprayed into gases containing steam and oxygen at 300-350 DEG  C.

Title: Hold-down attachment for a skinning machine
IPC: A22C17/12
Filed: 1970-03-16
Abstract: 1,272,172. Skinning machines. TOWNSEND ENG. CO. 16 March, 1970 [18 Aug., 1969], No. 12590/70. Heading A2U. A piece of meat is skinned by being passed horizontally through a skinning machine whilst it is simultaneously subjected to compressive and lateral stretching forces to hold it in a flat condition. One embodiment of skinning machine comprises a feed table 18 on which a conveyor belt 20 advances a slab of meat 22 towards a roller 12 which feeds the meat past a blade 16 by which the skin 24 is separated from the meat. The compressive and lateral forces are applied to the slab by a holddown roller in the form of a plurality of roller elements 50 made of resilient material and rotatable by a shaft 44 which is carried by spring-loaded arms 38, 40. Each element 50 has a rim 64 of conical form with grooves 66 and a web of reduced thickness between the rim and boss, and the elements are arranged in two groups 52, 54 with their conical surfaces diverging in the direction away from the middle of the roller so that the compressive force with which the elements 50 engage the slab tends to cause their outward deflection with accompanying lateral stretching of the slab. The roller 12 has longitudinal serrations 34 and annular grooves 28 coacting with cleaning blades 30. In a modification, the roller elements 50 are replaced by groups of shoes 90, Fig. 11, each group comprising four shoes pivotally mounted on arms 102 and loaded by springs 110. Each arm 102 is pivotally mounted on a rotatable structure comprising four square rods 82, 86.

Patent GB-132676-A (GB)
IPC: B21J7/12
Abstract: 132,676. Lindberg, W. Nov. 27, 1918. Power hammers.-A spring hammer for forging metals is so constructed that the spring, which is adjustable, is automatically disconnected from the crank-actuated lever system before the blow is actually struck, thereby preventing damage to the spring. A hammer 3 is raised to mid-position from an anvil 2, and, from this position, it is raised bv a belt-driven crank 8 and a connecting-rod 7, which depresses the left end of a lever 5, thereby causing a spring 9 in a socket on the end 5<a> of the lever to raise the lever hammer 4, which is loosely mounted on the pivot 6 of the lever 5. The movement of the lever is transmitted to a lever 10 with a roller 12 which bears on lever 4, and a laminated spring 13 is compressed through a yoke 20 and bell-crank lever 19 which bears on the end of the spring. As the end of the lever 5 is raised by the connecting-rod 7 after it has passed through the dead-centre position, the lever 10 is caused to press on the lever 4, and, as the spring 13 can then expand and also act on the lever 10 to depress the lever 4, the blow of the hammer is effected under the double action. of crank 8 and spring 13. The lever 19 becomes detached from the spring 13 before the actual blow is struck. The spring 18 is carried by an arm 15 on a shaft 14 carried by an adjustable slide 21 which can be locked in the desired position, and the tension of the spring can be adjusted by an eccentric 17 and a hand-lever 16 which controls the position of the arm 15. In place of the laminated spring shown, other arrangements of laminated or spiral springs may be employed.
