IPC: B21D28/06
Filed: 1991-10-15
Abstract: Forming die assembly (18,20) for carrying out a U-ing operation on a flat blank (58a) has a forming tool (80) in one (18) of two ram assemblies (18,20) which cooperates with a second forming tool (94) to perform the U-ing operation. During movement of the ram assemblies (18,20) towards each other, the forming tool (80) is retracted and remains stationary during a final portion of the stroke of the ram assembly (18) in which it is carried. The forming tool (80) is maintained in an extended position by a toggle mechanism (108) during an initial portion of the stroke and the toggle is broken during a final portion of the stroke thereby to permit the forming tool (80) to retract relative to the assembly (18). On the return stroke, the forming tool (80) is restored or shifted to its extended position by a biasing spring (150).

Abstract: A parallel and pipelined computer processor having a plurality of arithmetic and logic units (ALUs) which process computer operations in parallel to speed up the operation of the computer. Operations issued during the branch delay period following conditional jump operations are conditioned on the outcomes of the condition evaluation of such conditional jump operations that have not yet gone through the instruction issue pipeline, by matching a field in the operation to path information generated by a branch control unit. Operations that succeed are allowed to proceed and the effects of unsuccessful operations are disabled. This allows look-ahead computation after a conditional branch which is particularly attractive for a VLIW processor having a large number of parallel functional units and allows useful work to be done in the branch delay periods. Optionally, only such operations that affect the programmer-visible state of the computer are so conditioned, e.g., store operations to memory, program flow control operations and operations that raise exception conditions. The matching algorithm can be implemented such that an operation is enabled on a single path or on an arbitrary set of paths.

Abstract: In response to user signals requesting motion of a displayed object, a system presents a sequence of images, each including an object perceptible as a moved continuation of the previously-displayed object. The user can independently request radial motion and lateral motion, and the system presents a sequence of images in which the object is displaced radially by the requested radial motion and laterally by the requested lateral motion. The user can request lateral motion by operating a mouse and can request radial motion by operating keys on a keyboard, with one key requesting motion toward a radial source and another key requesting motion away from the radial source. The radial source can be the viewpoint. The object's motion toward the viewpoint includes two phases. In the first phase, the object follows an acceleration path, enabling the user to control motion near its starting point and providing increasingly rapid motion; in the second phase, it follows an asymptotic path, enabling the user to control its motion as it approaches the viewpoint and preventing it from passing the viewpoint. The displacements between positions on the asymptotic path can follow a logarithmic function, with each displacement a proportion of the distance from the previous position to the viewpoint. The phases can be produced by using the logarithmic function to clip an acceleration function. The same rate of acceleration can be applied when the user requests motion away from the viewpoint. The processor can perform an animation loop, each step of which receives user signals and presents another image.

Abstract: A hydraulic lifting truck having a shear support comprising two forks and at the lower end of a shear (11) comprises a thrust pad (14) is made to give the user a forewarning of the risk of an imminent tilting as a result of a forward displacement of the centre of gravity on the forks. In a normal lifted and stable state the thrust pad (14) rests on the support (2) on a first supporting surface (20). If the centre of gravity is displaced forwards on the forks, the thrust pad (14) may tilt around a line (22) which separates the first supporting surface (20) from the second supporting surface (21) and the lifting truck then reaches a new stable but slightly tilted position at the second supporting surface (21) resting on the support (2). In this situation the user will usually displace the centre of gravity or lower the forks to re-establish the stable supporting situation, which is illustrated in Fig. 5. If, however, a further displacement of the centre of gravity occurs, a further tilting takes place thereby bringing a third supporting surface (25) on the thrust pad (14) into contact with the support (2). This situation will define an unstable state of equilibrium which gives the user a final indication before the lifting truck tilts forwards.
