Abstract: ABSTRACT OF THE DISCLOSURE:         A deadlock mechanism comprises a casing having a facing plate provided with a bolt aperture and a bolt movable through the aperture between an unlocking position and a locking position.  This bolt is connected to a reciprocable plunger, the bolt being made up of a pair of levers each having a locking ear at its forward end and a caming lug at its rearward end, the rearward ends of the levers being pivotally mounted at the end of the plunger so as to pivot in opposite directions when the bolt moves out of the casing into locking position.  Movement of the bolt and pivoting of the levers as they move in and out of the casing is obtained by the coaction of caming edges on the levers and cam followers within the casing.

Abstract: ABSTRACT     Problems of wear and bounce created by imperfections in the surface of a magnetic recording medium, such as a chromium dioxide-coated drum, are circumvented by a hydrodynamic magnetographic imaging technique that provides the intended effective intimate contact between the recording head and the magnetographic recording surface.  A liquid (e.g. water) is applied to the surface of the drum slightly upstream of the location of the recording head, so as to create a liquid bearing against which the recording head is urged, and thereby intimately magnetically coupled with the surface of the drum, except for an extremely thin liquid film between the head and drum surface.  As a result of this extremely thin liquid bearing, continuous pressure can be applied to the head to maintain the head in effective intimate contact with the surface of the recording medium without the fear of scratching the medium or causing wear on the head.

Abstract: FAULT-TOLERANT ATOMIC BROADCAST METHODS            Abstract of the Invention A method for reliably broadcasting information in a point-to-point network of processors in the presence of component faults provided that the network remains connnected using only an exchange of messages. The method possesses the properties (1) that every message broadcast by a fault-free processor is accepted exactly once by all fault-free processors within a bounded time,  (2) that every message broadcast is either accepted by all fault-free processors or none of them, and (3) that all messages accepted by fault-free processors are accepted in the same order by all those processors.     The method is based on a diffusion technique for broadcasting information and on special message validity tests for tolerating any number of component failures up to network partitioning or successful forgery.
