Abstract: In a book binding operation, opened covers are brought into alignment with moving book blocks by a feed system which applies a pneumatic hold-down force to the moving covers. This hold-down force provides for a braking effect which varies as a function of the characteristics of the cover, the braking effect minimizing the chances of overshoot. The hold-down force also provides a stiffening effect, in the direction of cover movement, which varies as a function of cover thickness and minimizes the possibility of crushing.

Abstract: Spine strip stock material, being withdrawn from a supply reel, is cut into pieces of the desired length and the pieces are subsequently fed into positionally accurate contact with cover boards which are moving on a conveying system. High cutting and feeding accuracy are achieved by a servomotor control system which, in response to sensing the motion of the cover boards, stops the infeed of the stock material, clamps and cuts the stationary stock material, feeds the cut spine strip pieces to a waiting position and then moves the pieces from the waiting position into contact with the cover boards.

Abstract: A book cover assembly apparatus includes a cover table and a transport arm. The transport arm has a vertically moveable suction head which carries cover boards to the cover table which is initially in an inclined acquiring position. The transport arm establishes an initial line of contact between an adhesively coated cover cloth disposed on the cover table and the cover boards. The cover table is pivoted to a horizontal position in synchronization with movement of the transport arm thereby progressively diminishing the angle included by the cover cloth and cover boards. Such combined movement causes the contact line to move across the cover cloth, rolling the cover cloth into contact with the cover boards.

Abstract: A level vial assembly for use in a carpenter's or mason's level. The assembly includes a vial mounting subassembly to be mounted in a level body, consisting of at least a vial holding plate and one or more vials which are mountable therein, and one, or preferably two, bezel-lens subassemblies for protecting the vial. The vial is positioned in the mounting plate between a pair of oppositely directed notches, and is held in position by a tab which extends outwardly from the side of the vial and bears against the holding plate. The tab limits lateral movement of the vial in one direction. The holding plate is mountable within an aperture in the level body. The bezel-lens subassemblies are mountable in the level body aperture on opposite sides of the vials. One of the bezel-lens subassemblies includes a vial support portion adapted to bear against the vial to prevent lateral movement in another lateral direction.

Abstract: A mobile paving machine which may, with minor modification, be employed either to distribute material along the path of movement of the machine or in a region which is laterally offset to one side of the motion path. In order to spread material in a laterally offset region, which may correspond to a break-down lane being formed along the side of a travel lane, a tiltable secondary skip is installed above the primary skip to which paving material is normally supplied. A scraper is mounted from an extension of the distribution beam of the machine to controllably disperse material discharged through an end of the secondary skip when the loaded secondary skip is angularly inclined to cause gravity induced flow of material into the lateral region.

Abstract: Intervertebral disc endoprosthesis with two prosthesis plates which are to be connected to the end plates of the relevant vertebrae, and with a prosthesis core which cooperates with at least one prosthesis plate via an articular surface permitting a rotational movement around the vertical axis, In order indeed to make possible a rotational movement around the vertical axis but to oppose this movement by a resistance, the articular surface forms curved arches of different average radius in the median section and in the frontal section. The radius of curvature in the sagittal section is expediently less than in the frontal section. To avoid excessive twisting it is possible to provide stops on the prosthesis plates and on the prosthesis core. These are designed, for example, as ribs and grooves which run in the median plane.
