Abstract: The present invention relates to a method for controlling the access, in a computer, of a memory having an erasure frequently limited by blocks. This memory contains utility memory blocks (NB0, NB1) which are available for a user's access by an address conversion occurring through a pointer panel (AZTO). An erasure utility category (LN0, LN1023) is maintained in the form of a table in association with each address pointer maintained in the form of a table in association with each address pointer (AP0 AP1023). This erasure utility category is increased every time a predetermined erasure-state criteria is reached. The other pointing positions of the erasure utility categories (LN0 LN1023) are further explored in the pointer panel (AZTO) until a lower erasure utility category is found. The corresponding address pointer (AP0 AP1023) is then permuted with the one located at the output with the one located at the output pointer position (AP1).

Abstract: In an attempt to form a compact arrangement of a control unit for a weaving machine, according to U.S. Pat. No. 3,759,298, undesired distortions result in the sequence of movement of the heddle frame due to the installation of a short connecting rod. To prevent this, the heddle frame actuating mechanism has one double arm lever pivotally supported on an arm of a further double arm lever, a connecting rod hingedly connected at its one end to a still further double arm lever. The arm of the further double arm lever and the arm of the one double arm lever are in alignment rectilinearly in the center-shed position and are together equal in length to the length of a first arm of the still further double arm lever, so that these two arms, the connecting rod and a connecting line extending between the fixedly arranged pivot axles for the further double arm lever and the still further double arm lever form a parallelogram.

Abstract: A draft sensing apparatus for an agricultural tractor or the like. The tractor is provided with a transversely extending bending shaft (18). The forward ends of a pair of lower draft links are secured to the outer ends of the shaft (18). The shaft (18) will bend in proportion to the draft in the links. The draft is sensed through a Hall effect device (52) carried by a yoke (54). The forward end of the yoke (54) is pivotally mounted on a fixed transversely extending shaft (48) and the rear portion of the yoke slideably receives the bending shaft (18). A link (60) pivoted to the yoke (54) has one end portion contacted by the shaft (18) and the other end is in contact with one end of a spring biased pin (70). The other end of the pin carries a permanent magnet (78) in axially alignment with the sensor (52). As the shaft deflects as the draft varies the magnet (78) will be shifted towards and away from the sensor (52) causing a voltage variation in line (98).

Abstract: A method and apparatus for connecting harness cords to the heddles which are eventually to be used in a weaving machine. A harness cord is threaded through an upper eyelet of the heddle and is turned back on itself with the connection being fixed by a shrink hose which is shrunk over the eyelet, thereby clamping the harness cord to the upper eyelet. An apparatus is movably mounted on an assembly frame between the various harness assemblages. At each location on the frame, the apparatus holds the free end of the harness cord after it has been threaded through the eyelet on the heddle. A friction brake is utilized to hold the free end of the harness cord while the apparatus effects a tightening of the harness cord and a drawing of the eyelet into the unshrunk shrink hose. A cutting mechanism is provided to sever the harness cord between the eyelet and the friction brake.

Abstract: A weaving machine comprising a dobby and a Jacquard machine as the control members, wherein the dobby is controlled from a single pattern card in the Jacquard machine. Harness cords connect the Jacquard hooks to the heddles and to a movably supported member in the dobby. The coordinated movements of the Jacquard hooks will effect a simultaneous movement of the movably supported member in the dobby so that operations of the Jacquard machine in response to the information on the pattern card will simultaneously effect an operation of the dobby.

Abstract: An improved pressure control valve which provides equal damping force in both directions of movement of the valve spool and which also provides negative feedback to partially negate fast transients leading to valve instability. The pressure control valve includes a valve body having an inlet chamber and an enlarged adjacent damping chamber. A valve spool is received within the chambers, the spool having a first portion and a second radially outwardly extending portion adjacent the first portion and disposed within the damping chamber. As the valve spool is shifted to an open position fluid will be expelled from the damping chamber through a first orifice, and as the valve spool returns towards its closed position fluid will be expelled through a second orifice, the orifices having cross-sectional areas proportionate to the volume of fluid being expelled so that equal damping will be obtained in either direction of movement of the valve spool.
