IPC: A61F2/30
Filed: 1980-06-12
Abstract: A prosthesis (10) for replacing a hinge type bone joint includes a first component (12) having a body portion defining a plurality of generally semi-circular distal bearing surfaces (46) extending therefrom and a proximally extending intramedullary canal stem. A second component (14) has a body portion defining a convex posterior surface, a plurality of semi-circular grooves configured to matingly receive the distal bearing surfaces of the first component (12), and a distally extending intramedullary canal stem (64). The second component (14) may further define a laterally positioned capitulum process having a distal surface (94) adapted to be abutted against by the head of a radius bone (89) upon implantation in cases where the prosthesis replaces an elbow joint. The first component (12) defines an aperture and the second component (14) includes a hook-like member adapted to detachably and hingingly interconnect the components in a slipfit fashion.

Abstract: A distance indicating system, particularly for a vehicle, includes a transmitter (8) to transmit a signal beam, and two receivers (10) and (12) one on either side of the transmitter (8) The transmitter and the receivers are mounted on the front of a vehicle, and if an object (24) is directly in front of the vehicle the transmitted signal beam will be reflected by the object (24) and received simultaneously by the receivers (10) and (12). A coincident gate (16) is actuated only in response to signals received simultaneously by the receivers (10) and (12), and the actuated gate (16) sends an output signal to an echo delay measuring circuit (18). This circuit (18) operates an audio tone generator (20) and an audio output indicator (22) thereby providing an aural warning for the vehicle driver of the presence of the object (24). A clock (14) switches the transmitter (8) and the receivers (10) and (12) on and off in a suitable sequence to prevent a transmitted signal being passed directly from the transmitter (8) to the receivers (10) and (12) and being passed to the coincident gate (16). The audio output (22) is not operated in response to signals reflected from objects to the left or right of the vehicle because the reflected signals do not arrive simultaneously at the receivers (10) and (12), and consequently the coincident gate (16) is not actuated.

Abstract: The specification discloses a method of stabilizing aqueous alkali metal aluminate solutions against precipitation of solids and/or the development of a cloudy appearance over a period of standing. The method comprises dissolving hydrated alumina and an alkali metal hydroxide in an aqueous medium in an amount sufficient to produce an aqueous solution containing at least 30% by weight of dissolved solids. The dissolved solids are then reacted in the presence of at least 0.02% by weight of an oligomeric or monomeric surfactant containing groups capable of bonding chemically to the aluminate thus produced. The resulting aluminate solution is found to be stable for a period of several months at least, and thus has a long shelf life making it attractive for use in a variety of industries.

Abstract: Le systeme d'avertissement utilise une isolation par relais (120) entre une boucle de commande contenant un commutateur (110) commande par le conducteur et une boucle d'actionnement (148) servant a mettre sous tension les feux de stop (114). Le relais contourne le commutateur (146) de la pedale de frein et est utilise pendant une recuperation d'energie ou un ralentissement en retrogradant les vitesses pour faire clignoter de maniere manuelle les feux de stop. Des signaux transitoires d'extinction a l'interieur de la boucle de commande, de la structure du relais, et de la boucle d'actionnement provoquent des retards electriques, mecaniques et thermiques qui prolongent la trainee du clignotement au-dela du relachement du commutateur manuel.
