Title: Point-of-egress control device for safely securing emergency exit doors
Inventor: LOGAN EMANUEL L
IPC: E05B65/10
Filed: 1982-05-14
Granted: 1987-05-27
Abstract: Apparatus for securing an emergency exit door includes a bolt for engaging a keeper, a dogging mechanism for dogging the bolt and a fluid throttling device disposed between the bolt and dogging mechanism. An electrical timer is connected to the dogging mechanism by a solenoid and starts to count upon an attempt to open the door. After a predetermined time interval has run, the electrical timer releases the dogging mechanism and allows the door to dopen. If the electrical timer fails to release the dogging mechanism, the door will still open if pushed due to operation of the fluid throttling device, which slowly shortens under pressure, allowing the bolt to clear the keeper. In accordance with a preferred embodiment of the invention, the bolt is mounted on the door frame and the keeper on the door so that the door may be conveniently retrofitted with the invention. In order to readily align the keeper with the bolt, the keeper is loosely mounted and guided into alignment with the bolt by a bevelled guide. Upon being latched by the bolt, the keeper is held rigidly between the guide and the bolt. After the door has been opened, it cannot be resecured for a predetermined relock time interval. If the door is shut within this relock time interval, the relock time interval restarts, allowing the door to be reopened without a delay. Each time the door is shut after being opened, the relock time interval is restarted. In order to maximize reliability, Hall-Effect switches are utilized to monitor the position and movement of the bolt and the condition of the solenoid.
Patent DE-3362378-D1 (DE)
Title: Lift drive control
Inventor: KINDLER GERHARD
IPC: B66B1/28
Filed: 1983-04-06
Granted: 1986-04-10
Abstract: In this drive control the regulating circuits for the rotational speed of a drive motor and of an eddy current brake are matched in their static and in their dynamic behavior so that a common regulator may be used for both regulating circuits. The matching is achieved by interposing a current regulation circuit for regulating the excitation current of the eddy current brake to the rotational speed regulating circuit. The output of the common regulator is supplied via a linearization member as a reference value to a regulator in the current regulation circuit during the deceleration phase. During the acceleration phase the output of the common regulator is supplied to a matching element matching the variation of the torque to the variation of the torque during the deceleration phase with respect to time. The output of the matching element is connected to the control member of the drive motor via a linearization member. By means of the linearization members the characteristics of a d.c.-shunt motor are approximately achievable. A distance regulating circuit is superposed on the rotational speed regulating circuit. The distance reference value is derived from jerk and acceleration magnitudes during the acceleration phase as well as during the deceleration phase, so that an optimum travel curve is achievable.

Abstract: An X-ray lithographic system has a high repetition rate, high power pulse laser generator (12) producing an excitation beam (14) which is focussed upon a target strip (64). At the intersection of the beam and the strip X-ray emitting plasma is formed, the X-rays passing through a window (28) onto an X-ray resist coated semiconductor wafer (32) through a mask (30). A cavity is formed initially in the strip by a laser pulse whilst the X-rays are prevented from passing through the window (28) by a screen (72), after which further laser pulses cause plasma to be formed in the cavity which emits X-rays whose intensity is greater within a cone formed at an angle (42) of the path of the beam, than the intensity of the X-rays emitted if the beam intersects a non-cavity area of the target. The target strip is wound upon a supply reel (66) and led to a take-up reel (68), so that it can be moved by incremental amounts as it is used up.
