Title: Laser system with interchangeable plasma chambers
Inventor: JAVAN ALI
IPC: H01S3/05
Filed: 1983-02-18
Granted: 1986-07-24
Abstract: A gas laser is provided in which the plasma chamber (2) can be quickly and easily replaced by relatively unskilled personnel. This feature makes it possible to use sealed plasma chambers (2) in applications where lasers are operated only intermittently and sealed plasma chambers (2) have limited operating life. With the elimination of the gas handling system, it becomes posssible to manufacture compact, and in some important cases, portable and light weight lasers with replaceable plasma chambers (2). The invention is addressed to lasers operating at low to medium power output. To make chamber (2) replacement possible without need for elaborate optical realignment, one section of a mating mechanical coupler (76,78,82,84) is secured to the non-conductive envelope (4) of the demountable plasma chamber (2) and is positioned in a predetermined spatial and angular position with respect to the electrodes (12,14), optical windows (26,28) and the optical axis of the plasma chamber (2). The positioning of the mechanical coupler with respect to the electrodes (12,14), the windows (26,28) and the optical axis is identical for each of the interchangeable plasma chambers (2). A separate base (32) is provided with the other section of the demountable coupler fixed in a precise predetermined spatial and angular position with respect to a pair of mirrors (52,54) mounted on the base (32). The position of this section of the mechanical coupler (76,78,82,84) with respect to the mirrors (52,54) is identical for each of the interchangeable bases (32).

Inventor: PRUNBAUER KURT
IPC: E05B27/00
Filed: 1983-10-08
Granted: 1988-02-04
Abstract: Disclosed are cylinder lock arrangements which include a rotatable cylinder plug provided with recesses for guiding in axial direction blocking bars which cooperate with the cylinder housing to prevent in a blocking position thereof the rotation of the plug. The blocking bars are formed with blind bores which in a releasing axial position of the bars communicate with a key channel. The blind bores accommodate segmented pin tumblers which are controlled by control recesses on a lateral wall of a key so that upon the insertion of a correct key the separation planes of the segments of the pin tumblers coincide with the separation plane between the blocking bar and the clyinder plug. The key for the lock of this invention has a profile defined by alternating longitudinal ribs and longitudinal grooves whereby the crest regions of the ribs are formed with the control recesses arranged at different levels in accordance with the segments of the pin tumblers.

Granted: 1989-04-20
Abstract: Apparatus for recording and reproducing audio signals on flat rectangular recording media comprising a magnetic coating or the like on at least one side. A magnetic head on a swing arm moves across the magnetic media in mutually parallel lines guided by a heart-shaped cam, the recording medium being stationary during recording and reproducing so its visible surface can be examined without difficulty. The heart-shaped cam is of asymmetric configuration, and the magnetic head is pivotably mounted on one end of the swing arm which carries between its ends a cam follower peg which continually engages the heart-shaped cam while under spring loading. The other end of said swing arm is pivotably mounted on a sliding carriage plate which is moved stepwise perpendicularly to the chord of the curved path of movement of the magnetic head for each line. The stepwise perpendicular movement of the sliding carriage plate is produced by a mechanism which is controlled by the reversal of direction of the magnetic head.
