Filed: 1992-03-13
Abstract: A pneumatic control device has a control cylinder with dovetailed guiding means with a guiding rail and a guiding groove for holding and guiding housings of reed-contacts or the like. The cross-sectional area of the substantially trapezoidal guiding rail of the contact housing has not the same shape as the trapezoidal cross-sectional area of the corresponding guiding groove of the control cylinder.

The total width of the guiding rail is unilaterally shortened to a size determined by a circle drawn around an edge at the narrow side of the guiding rail having a radius (133) that is at the maximum equal to the gap width (12) of the guiding groove (12). The spacing (134) between the other edge of the narrow side of the guiding rail (132) and the diametrically opposed outer edge (135) of the guiding rail (132) exceeds the gap width (121) of the guiding groove (12).

Inventor: COULSON RICHARD L
IPC: G06F13/28
Filed: 1992-08-18
Abstract: An apparatus and a method facilitate the sharing of a SCSI address ID between a SCSI initiator and a target device. The SCSI standard does not prohibit ID sharing under certain operating conditions. The shared ID is preferably used by a monitor device 70 that controls the power of disk drives 30A, 30B, 30C on the SCSI bus, detects their status and configuration, and monitors environmental conditions within a mass storage system cabinet. Power to individual disk drives is switched under control of the computer operating system so that start-up surge current to the disk drives is limited. This allows defective drives to be powered down and replaced without powering down the remaining good drives. SCSI termination power distribution is improved so that connector reversals can be detected and resulting current surges limited. Termination power control and status is under program control, 28, 100. The reliability, utility, and cost-effectiveness of large SCSI bus-based mass storage systems is improved through the use of this invention. <IMAGE>

Inventor: EYRING GERD DR
IPC: G01B11/25
Filed: 1992-10-22
Abstract: Laser sources (1,7) produce beams (A,B) of coherent light of differing wavelength. Beams A and B are combined using half-silvered mirror (8) and mirrors (2,3,4,5) then focussed by lens (6) to illuminate the object (M) and a reference body (V) in field (S).
