Abstract: A digital display arrangement is provided for balanced general timekeeping having centrally-positioned hour digits and two sets of smaller, equal-sized minute digits flanking the hour digits for trailing and leading readout, with hockey stick-shaped display elements positioned below the minute digits and oriented to give graphic symbols of minutes increasing past the present hour and minutes decreasing toward the next hour, respectively. Means are provided for blanking the hour digits and simultaneously energizing a chronograph time display which, because of resulting large spaces uniquely seen only between the chronograph digits, presents substantial visual contrast from, and minimum potential for ambiguity or confusion with, the general timekeeping mode.

This is suitably accomplished by a ramming device arranged at one end of the knife with the knife being pivotably supported by a frame on its opposite end.

Abstract: An ink jet nozzle head comprising a first nozzle head member having a surface on which hydrophilic sections of a predetermined width and hydrophobic sections of a predetermined width are formed alternately and in parallel with one another, and a second nozzle head member having a surface of the same configuration as the surface of the first nozzle head member, these members being opposed to each other to form a very small space therebetween, whereby a plurality of nozzles are formed along the hydrophilic sections. The hydrophilic sections of the second nozzle head member may be positioned just above those of the first member or offset therefrom. The nozzle openings formed between the two members are formed to have acute angle edges.

Abstract: A number of three-layer optical fibers each having a core a cladding and an overcoating layer of acid-soluble glass material are bonded together by means of an adhesive which can be removed by applying heat. The bonded optical fibers are heated and stretched to obtain a solid optical fiber bundle. The solid optical fiber bundle is brought into contact with an acid to elute (leach away) the overcoating layer of the acid-soluble glass material.

Abstract: The present invention relates to a lock system comprising a lock of the type where the combination of the lock is given by a more or less platelike code member which may be removed and substituted and where the lock is operated by means of a more or less platelike key member. The key member is equipped with a code adapted to the code of the code member. The lock comprises a housing and means intended to be activated by the code of the code member and/or the code of the key member, said means reading the codes. Parts of the code on the key member may be read mechanically, using blocking pins while parts of the code may be read optically and/or electronically by means of light diodes emitting infrared light.

Abstract: The invention relates to apparatus for machining circular saw blades and more particularly to the transport means for conveying workpieces to the machining stations of the apparatus. In accordance with the invention, the storage capability of the apparatus is accomplished by subdividing the conveying means into a work path leading through the machining stations; a return path leading through a feeding and discharging station; two branch paths wherein an endless conveyor is arranged only along the work path and associated with the branch paths there are shifting means capable of shifting a work piece carriage from the branch path to the return path; and that on the return path, work piece carriages are maintained at smaller distances than those of the endless conveyor whereby the storage capacity of the apparatus is increased. The apparatus is also adjustable to feed a plurality of different saw diameters for machining.

Abstract: The invention relates to an improved safety device for stopping cable payout in an overspeed condition, and particularly to a safety device for securing an object from falling because of failure of a hoisting device. According to the invention, an inertial actuated drum locking mechanism comprises an inertial member mounted on a cable rewind drum. The inertial member is pivotable so that when actuated by inertial force above a predetermined value due to overspeed rotation of the drum, the inertial member moves to engage a fixed member for arresting further motion of the drum. The inertial member is held in place until the outward force exceeds the predetermined value, at which point, the inertial member toggles outward to provide rapid and positive engagement of the locking mechanism.

Abstract: A cylinder lock assembly is provided with a cylindrical plug that may be interchanged and used in different exterior body members without changing the exterior body member of the assembly. This is of advantage to eliminate the need to stock a variety of expensive cylinder assemblies for plugs having different keyways or keys with different bitting locations. It is only necessary to maintain a supply of different plugs and keys. Commonality of parts for mortise and rim type locks also reduces inventory required in commercial and institutional establishments.The pin bores in the exterior members and the pin bores in the plugs are located a constant distance away from a selected reference point in the lock assembly and the exposed keyway face of the plugs. As a result, the pin bores in one or more plugs will align with the pin bores in one or more exterior body members so that the plugs may be used with different exterior body members.
