Patent GB-994077-A (GB)
Title: Apparatus and method for measuring oxygen tension in bone
IPC: A61B5/00
Filed: 1961-09-11
Abstract: An apparatus for determining whether a bone is alive or dead comprises an outer tubular electrode and a concentric inner electrode insulated from it.  These are preferably made of silver and platinum respectively.  This device is inserted in a hole in the bone so that oxygen containing blood, if present, comes into contact with the end of it.  The blood then either forms a conducting electrolyte between the electrodes or, in a modified construction, oxygen from the blood passes through a covering membrane into a pad secured at the end of the electrodes and soaked in saline solution.  In either case, the current flow for a given voltage applied across the electrodes is a direct indication of the proportion of oxygen in the bone and the absence of oxygen is a clear indication that the bone is dead.  The apparatus is particularly applicable to cases where the neck of the femur is broken and the head of the femur may be dead, since the electrode assembly may be inserted in the hole which is necessarily drilled in the femur before operation.

Filed: 1946-11-05
Abstract: 642,100. Lifting-dogs. SOMERS, Ltd., W., and SOMERS, F. J. Nov. 5, 1946, No. 32776. [Class 78 (iv)] In lifting-tongs of the kind comprising a pair of gripping arms 7, 7 pivotally connected to one another at 8 and connected at their outer ends to toggle links A which are pivotally mounted on a pin B carried by a hook on a lifting-chain, automatic means for locking the arms 7 in the open position and for releasing them from this locked position when a load is to be gripped comprises a rotatable T-headed pin 3, mounted for axial movement in a recessed bracket 1 supported by the pin B and one of the links A, and engaging in its locking position behind the shoulders of a recess 6a in a member 6 secured to one of the arms 7. When the tongs are lowered to engage a load, the pin 3 is pressed upwards whereby pins 2 extending into the recess 1a of the bracket 1 strike inclined faces 4a on the lower ring of two cam rings 4 on the pin so as to rotate the pin 3 through 45 degrees. If now the toggle links are opened by an upward lift of the lifting chain, the faces 4a of the upper cam ring 4 will strike the pins 2 and rotate the pin 3 through a further 45 degrees so that the head 5 lies in alignment with the slot 6b in the member 6 and is free to be lifted, thereby allowing the arms 7 to close on the load. When the load is to be released, the links A close down on the arms 7 and the head 5 passes through the slot 6b and strikes the bottom of the recess 6a. This causes the pin 3 to lift and the cam surfaces 4a of the lower ring 4 to strike against the pins 2 and so rotate the pin 3 through 45 degrees. When the toggle links are raised, the pins 2 will strike the cam faces 4a on the upper ring 4 and rotate the pin 3 through another 45 degrees, causing the head 5 to lie at right-angles to the slot 6b and engage the shoulders on the locking member 6.
