Title: Blood coagulation time measuring device
IPC: B01F13/08
Filed: 1978-02-22
Abstract: A blood coagulation time measuring device includes a stirrer drive arrangement for rotating a stirring rod placed inside the measuring vessel when the vessel is inserted in a measuring channel of the device. A light detector assembly within the device determines the degree of coagulation formation in the measuring vessel by transmitting a light beam from a light source through the measuring vessel and onto a photo-electric cell. Light balancing circuitry coupled to the light source and the photo-electric cell automatically adjusts the brightness of the light from the light source in correspondence with the turbidity of liquid in the measuring vessel. A control switch arrangement operates to turn the stirrer drive arrangement on or off in response to operation of the light balancing circuitry.

Title: Load-stabilizing prosthetic joint and connecting component thereof
IPC: A61F2/42
Filed: 1979-03-07
Abstract: A load-stabilizing prosthetic joint is comprised of three basic components. A first component is adapted to be associated with a first bone and has an arcuate bearing surface and a shank terminating in a headed member. A second component is adapted to be associated with a second bone adjacent the first bone and has a terminal portion with rigid walls defining an open ended socket. A third component, for connecting the first and second components, has an internal cavity and a passage communicating therewith. The third component is sufficiently flexible to permit the headed member to be passed through the pasage into the cavity to connect the first and third components. The rigid walls of the second component embrace the third component providing support therefor, and prevent the headed member from passing outwardly of the passage in use. Included on the third component is an arcuate bearing surface mating with the arcuate bearing surface of the first component, the bearing surfaces cooperating to carry the loading forces of and stabilize the joint in use. This joint includes cooperative locking means between the second and third components to prevent their separation under lateral displacement between the first and second components.

Title: X-ray apparatus for producing tomographic and other radiographic images.
IPC: A61B6/02
Filed: 1980-07-04
Abstract: An X-ray apparatus in which the X-ray source and the image recording device can be detachably interconnected by means of a coupling device.

Title: Method for curtailing phosphorous impurity in the production of AlF3.
IPC: C01B7/19
Filed: 1982-01-04
Abstract: In the production of hydrogen fluoride gas for the production of AlF3 by the reaction of fluorspar with concentrated sulphuric acid a small amount of aluminium sulphate is introduced into the reactive mix to assist in the retention of phosphorous compounds in the solid residues of the reaction and thus reduce the phosphorous content of the gaseous HF. Aluminium sulphate may be added as alum or may be generated in situ in the sulphuric acid by addition of an alumina hydrate, preferably before the acid is brought into contact with fluorspar. The addition of a small amount of calcium carbonate to the fluorspar also improves retention of phosphorous compounds in the solid residues in some instances.
