Abstract: The invention relates to an arrangement for enabling the connection of a position sensing transducer to a machine such that the transducer is not subjected to high temperatures or dirt. In accordance with the invention the transducer is mounted on the outside of a housing in which there is mounted a rotatable means which extends outside the housing to operate a drive means for driving auxiliary equipment. The invention is distinguished in that the position sensing transducer includes a disc fixed to the drive means, said disc co-acting in non-contacting relationship with a transducer mounted on the outside of the housing for indicating the angular positions of the disc, and in that the drive means and housing include portions concentrically disposed to form a labyrinth seal to a space which accommodates the position sensing transducer.
Abstract: A device for measuring the oil level in an internal combustion engine, which enables an oil dipstick to remain in the oil filling opening to engines even during filling. At its upper end the dipstick is connected to a cap for the oil filling opening, and the dipstick is intended to be accommodated in a tube or a like device communicating with an oil container for the engine. The invention is substantially distinguished in that the dipstick is articulately connected to the cap and allows tilting of the dipstick relative the cap, enabling the cap to be hung on the upper edge of the tube during oil filling.
Abstract: Seat plate (10) for supporting the pelvis of a person sitting in a seat (2), e.g. a seat in a vehicle. Known seat implementations only give limited support in a horizontal direction. This causes a noticeable problem in vehicle seats, since a person sitting on one is subjected to accelerations and retardations in both longitudinal and transverse directions. The muscles which are activated in such cases become tired relatively quickly, often resulting in that an incorrect sitting attitude is assumed which can give rise to skew loads as well as accelerating and amplifying the sense of tiredness and soreness. The invention relates to a seat plate (10) for positioning the pelvis of a sitting person so that no notable muscular work is required for maintaiing a correct sitting attitude. The seat plate (10) is thus formed with two raised, scythe-like ridges (11) each including a forward transverse ridge portion (13) and a longitudinal ridge portion (14) extending backwords from the transverse portion (13).
Abstract: The invention relates to an ignition system for a multi-cylinder Otto-type four-stroke engine equipped with at least one spark plug per cylinder, the ignition system including for each spark plug an ignition device (61, 62) connectible to said spark plug in the engine substantially without cables, the ignition system also incorporating a control unit (8) sending signals in response to the engine operating conditions for triggering sparks at the spark plugs in a predetermined order. In order to ensure, in such ignition systems, transmission of maximum ignition voltage to the engine spark plugs and enable simple and safe handling of the ignition system during service and the like, the invention is mainly distinguished in that the ignition devices (61, 62) to at least two adjacent spark plugs are included in a common, handleable unit, a so-called ignition cassette (70).
Abstract: The invention relates to a roof rack section for attaching to a vehicle roof. Known such sections usually include a cross member having a foot attached to either end. Each such foot is provided with means for locking the section to the vehicle. Such known means often comprise screwed details which cause time-consuming and difficult fitting and removal of the roof rack sections. The present invention relates to a roof rack section including a crossbeam provided at either end with a foot which is formed with means for removably attaching the section to the body of a vehicle so that the section assumes a transverse extension above the vehicle roof.
Abstract: A connection device in an ignition system for transferring current to the spark plugs of an internal combustion engine includes a comparatively rigid outer sleeve intended to surround an upper portion of a spark plug, a contact for conductive communication with a central electrode of the spark plug, an elastic inner sleeve surrounded by the outer sleeve for tightly sealing against the upper portion of the spark plug when the connection device is fitted to the spark plug, a space being formed between the outer sleeve and the inner sleeve for allowing radial expansion of the inner sleeve, the outer sleeve and the inner sleeve having lower portions which include coacting portions for transferring force between the outer and inner sleeves, whereby for an upwardly directed force on the connection device fitted to the spark plug, force is transferred from the outer sleeve to the inner sleeve, and causes the inner sleeve to relinquish the spark plug.
