Title: Resiliently deformable bone staple for osteosynthesis
Inventor: THOMAS GARETH
IPC: A61B17/064
Filed: 2009-06-18
Abstract: The present invention provides a staple for fusing bones. The staple 100 has three or more legs 102a, b, c, d which are linked by a flexible connector 108 in a ring. The staple 100 may be expanded by forcing the flexible connector 108 over a tapered expanding tool (500, fig 5), using a receiver tool (600, fig. 8), to reach an expanded state. The staple is then inserted into the bone pieces and allowed to contract towards its relaxed state, thus fusing the bones together. Each staple leg may have a spike 106 at the end and barbed teeth 104 to aid gripping the bone into which it is inserted. The bone may be pre-drilled to accept the staple spikes. The flexible connecting region may be made from a shape memory metal alloy, such as NiTi (Nitinol). Also claimed is a method of fusing bones using the staple 100, a method of expanding the staple 100 using the expander tool, a receiver and a punch (700, fig 7), and a staple assembly comprising the staple, an expander, a receiver and a punch.

Patent GB-879449-A (GB)
Title: Improvements in production of alumina
IPC: C01F7/08
Filed: 1958-03-31
Abstract: In the production of silica-free alumina from a raw material containing iron and only a very small amount of silica, relative to the alumina, by sintering with sodium carbonate to form sodium aluminate which is leached out from the insoluble ferric oxide and treated to precipitate alumina, the removal of silica is effected by including a large excess of lime in the sintering charge, which at temperatures above 1700 DEG F., reacts with all the silica, and the equivalent amount of the alumina, to form calcium aluminium silicate which is insoluble in the leach solution and remains with the ferric oxide residue when the aluminate leach liquor is removed.  In order to avoid premature deposition of aluminium hydroxide from the aluminate solution, a sodium hydroxide concentration may be provided in the leach liquor by adding excess sodium carbonate to the sinter charge, which, with the excess lime, forms the required sodium hydroxide on leaching.  The initial alumina source material may be the product of the first stage of the process of Specification 857,245, where clay is treated with dilute hydrochloric acid to form and separate aluminium and iron chlorides which are decomposed by heat to form a low silica iron-containing alumina.  The sodium carbonate component may be mixed with the alumina as a concentrated solution recovered from decomposition of the sodium aluminate with carbon dioxide.

Abstract: 715,541. Reciprocating motors. ELMEG ELEKTRO-MECHANIK, GES. April 28, 1952 [Oct. 29, 1951], No. 10684/52. Class 35 An electromagnetic hammering tool 19 is controlled by a main energizing relay 11 and an auxiliary relay 3 under the influence of a rotating timing device 7 controlling a change-over switch 8, 10. During the greater part of the time, the contact 8 energizing relay 3 is closed, but during a comparatively short period, when the cam 9 is in operation, this contact is interrupted and the contact 10 is closed. This energizes relay 11 which closes contacts 14, 15, 16 causing the actuating coil 17 of the electromagnet to be energized through rectifiers 18 from the main supply. Motion of the armature 19 causes the opening of a limit-switch 20 which de-energizes the auxiliary relay 3, and the extreme movement of the armature opens limit switch 23 thus de-energizing the main relay and so cutting off the supply to the coil 17, the armature being spring-returned.
