Abstract: The arrangement comprises mounting supports for the spring slats, insertable in the longitudinal beams of the bedstead, with two upper spring-slats serving as a support for the mattress and undulating spring-slats situated below them. A tiltable holding part having four receptacles for the spring-slats is fitted on a plug of the mounting support. Below the plug there is a resilient bearing pad enabling the holding part to deflect vertically. The upper spring-slats are bent convexly upward and have a broadened cross-section in the middle. By means of the undulating lower spring-slats, a progressive spring action is achieved. There is no sagging of the mattress in the region of heavier parts of the body, optimum spring action being ensured nonetheless. It is possible to divide the bedstead into zones of differing degrees of firmness by selectively providing mounting supports with only upper spring-slats or with additional lower spring-slats.

Abstract: Folding tables on passenger seats are usually hinged to the underframe of the passenger seat with two lateral struts. As a result, when the table plate is folded down not only is the leg-room of the passengers restricted but also there is a very large risk of injury in the event of an accident. In order to remedy this, it is proposed to attach the table plate to the underframe of the passenger seat solely by means of a single central strut. <IMAGE>

Granted: 2001-06-12
Abstract: A regulator controls the DC current flowing through a load, where the current is initially supplied by an AC voltage source and thereafter rectified, the control being proportional to the load current. In one embodiment, the source-emitter potential of a transistor which functions as a control element is changed by means of a current source such that a current of predetermined strength flows through the control element transistor. The control current for the current source is derived from a current sensor in the load circuit. Additionally, a constant gate potential for the transistor control element is obtained through the current sensor. This circuit is preferably suitable for the regulation of the cathode current of travelling-wave tubes.
