Title: Eliminating position errors in robotic wrists, e.g. for telerobotics applications, using inverse kinetics scheme based on robot motion limiter and tool centre point position compensator
Inventor: FRIDENFALK MIKAEL
IPC: B25J9/16
Filed: 2002-10-30
Abstract: Position errors near and on inner kinematics singularity points are eliminated using an inverse kinematics scheme based on AC, where A is an inverse kinematics calculator followed by a limiter that limits robot motion with respect to kinematics and dynamics constraints of the total robot system, including its surrounding environment and incorporating properties such as maximum joint, velocity, acceleration and torque limits. The limiter can decrease or equalize constraint values in the neighbourhood of singularities for enhanced control stability. C is a compensator which modifies the position of the tool centre point (TCP) for the robot on the basis of A, building a transformation matrix Pout by concatenation of the position part of Pin and the rotation part of Plim.

Abstract: The invention relates to a process for producing heat-generating counter-measures which are intended to be dispensed from sea-based, land-based or air based systems, with heat being generated when an iron compound reacts with oxygen thereby forming iron oxide. The invention also relates to a pack (1) containing heat-generating counter-measures (8) which pack comprises a container (2) and a lid (3), accommodates heat-generating counter-measures and is intended to be dispensed from sea-based, land-based or air-based systems, with heat being generated when the pack (1) is opened, during the dispensing, such that the content of the pack in the form of an iron compound makes contact, and is allowed to react, with oxygen thereby forming iron oxide and heat. According to the invention, the iron compound which is to react with oxygen consists of iron sulphide. The invention provides a less complicated process for producing heat-generating counter-measures, which process does not require the use of vacuum chambers or special spaces containing a protective atmosphere and which, at the same time, makes it possible to produce reliable packs which have an effective action.

Title: Brush for cleaning rainwater gutters along facades at foot of roofs
Inventor: BORG HAAKAN
IPC: E04D13/076
Filed: 1994-07-04
Abstract: The roof gutter cleaning brush has a head which is supported by a tubular frame, whose length is matched to the distance between the gutter and the ground level. From ground level, an operator can carry out cleaning work with a draw line coupled to the effective link system of the brush head. The draw line imparts a swinging movement to the brush head so that the head point follows the gutter bottom surface, thereby removing collected contaminants. When the operator has taken up the position for cleaning, the brush rests partly with its support arches against the outer edge of the gutter and partly with its frame in a body support against the middle of the operator.

IPC: F02M57/02
Filed: 1994-07-18
Abstract: The design and manufacture of past fuel injection systems required extensive modification of the cylinder head in order to provide and actuate hydraulically actuated fuel injectors. Additionally, methods to avoid the cylinder head modifications have presented reliability concerns. The present invention overcomes these problems by providing an adapter assembly releasably connected to the cylinder head. The adapter assembly includes an adapter which has an integrally formed actuating fluid manifold and an integrally formed fuel manifold. The present invention provides a means for communicating between the actuating fluid manifold and the actuating fluid inlet passage of a hydraulically actuated fuel injector and a means for communicating between the fuel manifold and the fuel inlet passage of the fuel injector. Actuating fluid is communicated through the actuating fluid manifold and into the actuating fluid inlet passage in order to actuate the fuel injector. This results in a more reliable system which eliminates costly modifications to the cylinder head.

Abstract: A bolt joint in an industrial robot for fixing a first body (1) to a second body (2). The joint allows a non-play transmission of a torsional force acting between the bodies. An expandable conical first sleeve (8) makes contact with a hole wall of a cylindrical hole (7) common to both bodies. The joint also comprises a conical second sleeve (9) which is adapted to penetrate into the first sleeve (8). A bolt (3) is arranged running coaxially through the sleeves. When the bolt is clamped, the second sleeve (9) penetrates, with force, into the first sleeve (8) and forces the first sleeve (8) to expand. The strong expansion results in the first sleeve (8) deforming deviations in the hole (7), such that it makes butt contact with the common hole wall.
