Title: "Ready-made" suspended bed, with assisted fold-away action, designed to provide the comfort of a conventional bed in a minimum of space
IPC: A47C17/80
Filed: 1982-08-27
Abstract: The invention relates to sleeping arrangements for persons in a space regarded as too small for this use. Its criteria are maximum comfort for minimum bulk. Pivoting on its shafts 6 and 8 at the end of its extension pieces 7, the bed rises above the windscreen of the vehicle and, by means of its articulations 17 and 18, matches the shape of the rise of the roof, thus folding into a minimum of space. Detached from its supports 13, it opens at its articulation 17 and rocks via its shafts 6 and 8 on its extension pieces 7. The most advantageous application of the invention is its use in campers, caravans or other dwellings which may or may not be mobile.

Title: IC engine idling speed regulation controller
Inventor: KUTTNER THOMAS
IPC: F02D29/02
Filed: 1983-10-28
Abstract: The speed governing system is for an i/c engine involving a governor pref. with proportional integral differential characteristics, and with a theoretical value deduced from a specific actual speed level. The difference between speed theoretical and actual levels is dependent upon the speed itself, and can be mathmetically calculated from the speed actual value and three other speed levels. Also used in calculation of the difference are at least the load and/or temp. values. The theoretical speed value has an upper limit. When speed is dropping, governing only occurs when there is a lower difference between theoretical and actual speed values than the corresponding difference value under increasing speed conditions.
