Abstract: A shape memory alloy (SMA) actuator predeformed in tension actuates a separation device mechanism. A segmented nut, which engages a threaded bolt to be held and released, is held together by a nut retainer that is movable with respect to the nut and is affixed to the SMA element. The SMA element is heated by an electrical resistance heater to cause it to return to its undeformed state, thereby moving the retainer relative to the nut segments. When the retainer disengages from the segments, the segments are free to move outwardly thereby releasing the bolt or other item. Ones of the shape memory alloy actuator have a plurality of parallelly arranged SMA elements, every other one of which is predeformed in compression and intermediate ones of which are predeformed in tension.

Abstract: A recline lift chair operates between an upright position and a reclined position under power such that the backrest moves away from an adjacent wall. The chair comprises a base to which is pivotally connected a lift mechanism. The lift mechanism is moved between an upright position and a lift position by a power actuator pivotally secured between the base and the lift mechanism. Pivotally supported on the lift mechanism is a recliner mechanism that includes a pair of four-bar linkages to which the seat and backrest are fastened. The power actuator acts through a control linkage of the recliner mechanism to move the four-bar linkages between an upright position and a reclined position. Movement of the four-bar linkages from the upright position to the reclined position locates the seat and backrest upwardly and forwardly relative to their respective locations when in the upright position to move the backrest away from the wall.

Abstract: A lift seat includes a seating surface, for example, a toilet seat, mounted on a supporting frame by a four-bar linkage. The four-bar linkage includes a lower link fixed to the frame and an upper link fixed to the seat. An armrest is attached to a front link of the four-bar linkage for pivoting therewith against the bias of the spring which loads the four-bar linkage as the seat is lowered from a raised position to a seating position. Energy stored in the spring is then available to lift the person from the seating position back to the raised position. A damper is connected to the four-bar linkage to prevent abrupt movement of the seat as the four-bar mechanism collapses and expands, while a gas spring is provided to initially resist movement of the four-bar linkage from either the expanded or the collapsed condition unless the armrest is initially rotated.

Abstract: A control device for a matrix printer in which the mechanical printing elements of the matrix printer are selectively triggered by the control device a certain time before they reach the desired printing spot on the information carrier in order to compensate for the fact that the printing head will move further over a certain distance between the triggering moment and the moment that the printing element actually hits the information carrier. This distance depends on the speed of the printing element. If the print signal, however, is always generated a constant distance before the printing element reaches the desired printing spot, this signal must be delayed as a function of the speed of the printing element if the printing head is to print accurately also during its run-up and slow-down. To this end, a delay device is provided which delays the print signal for the relevant printing element by a time interval which depends on the printing head speed.
