  • Patent number: 7845660
    Abstract: The invention relates to an anti-roll/pitch system for use in a vehicle, in which a first mass, for instance a cabin, is suspended to a second mass, for instance a chassis, by means of a bearing arm, which is pivotally connected to the second mass around a pivot axis, via spring means. The anti-roll/pitch system comprises means to adjust a point of application of a spring force acting on the bearing arm, so as to adjust a moment exerted by said spring force on said bearing arm to counteract a load exerted on the bearing arm by the first mass. The spring force is exerted on the bearing arm through a flexible, elongated member, such as a string or cable, which takes up little space when adjusting the point of application. The invention furthermore relates to a built-in unit and a vehicle, equipped with an anti-roll/pitch system according to the invention.

  • Patent number: 5725186
    Abstract: Adapter bracket mechanisms for securing various roll-up signs to a sign stand. The bracket mechanisms are positioned vertically upright from the base of a sign stand. The adapter bracket mechanisms hold the lower end of the vertical cross brace of the roll-up sign. The mechanisms include a U-shaped channel and either a slide bar or pivoting lever arm member for enclosing the cross brace within the channel. A threaded turn-lock member securely holds the sign in the adapter bracket mechanism. If desired, a protector member can be used to help hold the vertical cross brace in the bracket mechanism and protect the cross brace from possible damage. Another embodiment utilizes a threaded knob to wedge the vertical cross brace in the channel.

  • Patent number: 5386962
    Abstract: A mount for a compressor or the like which sits on a base includes a top surface which is securable to the base. The top surface defines a well having a floor. An opening is formed in the bottom of the floor and a shaft extends from beneath the well floor to above the upper surface. The shaft includes a lower flange positioned below the well floor and an upper flange positioned above the top surface. A spring is positioned between said well floor and the top flange to absorb vibrations and any resulting shock produced by the compressor. A pair of upwardly extending generally perpendicular walls are provided on the upper surface to prevent the spring from engaging the upper surface or deflecting excessively. The walls and the upper flange are sized such that when the shaft moves with respect to the well, the upper flange will contact the wall before the spring contacts the upper surface or deflects excessively.

  • Patent number: 5163445
    Abstract: System for measuring a characteristic of flow of liquid in a vessel of a patient comprising a transducer positioned in a vessel in a patient for supplying ultrasonic energy. The transducer produces a substantially uniform beam which encompasses the vessel. The transducer receives ultrasonic energy back scattered from the red blood cells and provides an electrical output signal. A first moment detector is provided which receives the electrical output from the transducer and provides a first moment signal. Normalization is provided to the output of the first moment detector to provide an electrical output representing a characteristic of the flow of the liquid in the vessel.

  • Patent number: 5067065
    Abstract: A shock absorbent bulbholder mounting assembly including a yoke support and a bulbholder interconnected by a pair of spring mounted subassemblies. Each of the subassemblies includes an elongated arm strap adjustably attached to rotate with respect to a respective arm section of the yoke support, and an elongated bulbholder strap attached to a respective side member extending from opposing sides of the bulbholder. The arm strap and the bulbholder strap are disposed in spaced parallel planes. The longitudinal axes of the straps are oriented at right angles to one another, and each end of each strap is connected by two springs to opposite ends of the other strap. Four springs thus span the gap between the straps and each spring is oriented at a 45.degree. angle with respect to the longitudinal axes of the straps.

  • Patent number: 5044587
    Abstract: The foot bearing the seat surface of a seat is divided at a distance of 20-30 cm from the seat surface. Between the mutually facing end faces of the two foot parts (5a,5b) a rubber cushion (9) is arranged, the circumferential area of which is widened to form a brake ring (11). The elastic restoring force, working counter to the inclination of the seat, of this cushion is reinforced by two further cushions (16,17) arranged within the foot parts (5a,5b). By means of the suitable arrangement of sliding elements with low friction (T1-T3), the mutual rotation between the two foot parts (5a,5b) is ensured.Thanks to this construction, the seat surface can be swiveled in a tumbling manner in such a way that every point of said seat surface moves on an imaginary spherical surface and thanks to the mentioned elastic restoring force, the seat part always returns automatically to its initial position.
