    Abstract: PCT No. PCT/GB91/00699 Sec. 371 Date Feb. 12, 1993 Sec. 102(e) Date Feb. 12, 1993 PCT Filed Apr. 26, 1991 PCT Pub. No. WO92/20206 PCT Pub. Date Nov. 12, 1992.A removable electrical unit 20 is described which incorporates a soft stop and releasing mechanism which is employed to prevent removal of the unit from its housing in an unsafe manner. In operation, the unit is pulled from the housing by means of a front handle 22 on the unit and when the unit is partially removed from its housing a stop block 72 on the unit engages a stop spring 90 on the housing. A second handle 30 on the top of the unit becomes accessible and is actuated to disengage the stop block and stop spring. The unit may then be completely removed from the housing in a safe two handed manner.

    Abstract: Electrical devices are located within a cavity in a chassis. An electromagnetic seal (10) is fitted to prevent electromagnetic interference passing down the air gap between the device and the chassis. The seal comprises a helical coil spring which makes regular electrical contact from the device to the chassis. The coil is under lateral compression between the device and the chassis to enhance this electrical contact.

    Abstract: A modular housing for first (20) and second (30) groups of replaceable functional units e.g. disk files comprises a chassis for supporting the units within a first compartment (110) extending along the length of a chassis support structure (10) and removable via opposite openings in the chassis. Replaceable cooling and power supply assemblies (50) are located within a second compartment (108) of the drawer and can be removed from drawer via one of the openings without removing either of the groups of functional units. The fan (60) of a combined cooling and power supply unit is arranged centrally within the second compartment such that it draws cooling air past the first group of units and exhausts air towards the second group of units.

    Abstract: An adjustable support for a display monitor includes a turntable to allow swivelling and carrying a pair of support tubes on which is mounted a slidable support beam. A carrier having cylindrical bearing surfaces co-operates with skid-pads on the support beam. By sliding the carrier with respect to the support beam the angle of the carrier and hence the angle of the display screen can be varied. A non-magnetic gas strut located in one of the support tubes compensates for the weight of the monitor/carrier assembly. The force exerted by the gas strut is shared between the support tubes by means of a pair of coupled rack and pinions which also allow convenient height adjustment of the support beam, carrier and display monitor.
