Abstract: A conveying apparatus with a first conveyor and a second conveyor is used a the welding apparatus and a welding method for container bodies and in particular can bodies between which conveyors the object to be welded is handed over. A control unit determines the take over position and/or the conveying travel of the second conveyor and controls the conveyors accordingly, so that the take over occurs at the determined position and/or with the determined conveying travel of the second conveyor. This allows an easy and swift changing of the welding apparatus to different sizes of the objects to be welded.

Abstract: The invention concerns a control device for at least one heating, air-conditioning, ventilation or refrigeration system with a memory for a temperature control program and a signal outlet. It is endeavoured to simplify the programming. For this purpose, the memory is arranged in an element (5), which comprises a communication interface (6) and which can be dismounted from the control device, the communication interface (6) being connectable to an external input device and the control device (1) comprising an electrical supply device (3) which can transmit electrical energy to the element (5).

Abstract: An apparatus for forming a duct includes a bending apparatus and a support apparatus. The bending apparatus includes a table, a cut off beam, and a leaf hinged to a forward edge of the table. The cut off beam is movable toward and away from the table to clamp or release a metal web being fed forward across the table and the leaf. The cut off beam repeatedly clamps the metal web to the table while the leaf pivots toward the cut off beam to form a duct section. The support apparatus includes a cross rod movable along pivoting support arms. As the metal web is bent to form the duct section, the support arms and the cross rod are moved to internally support the duct section.

Abstract: A hydraulic machine has a gear wheel (2) with outwardly extending teeth and a gear ring (4) with inwardly extending teeth formed by rollers each of which is supported in a pocket (8) in the gear ring, and pressurized spaces are formed between the gear wheel and the inwardly extending teeth. To keep the wear of the machine small, each pocket (8) has at least two different radii (R1, R2, Rn) whereby a radius (R2, Rn) at a smaller displacement from the edge (12) of the pocket is larger than a radius (R1) at a larger displacement from the same edge (12) of the pocket (8).

Abstract: A hairbrush 10 has rounded outer surfaces 23, 25 of hinged heads 22, 24 that, when the brush is closed, achieve a closed form that is generally round or spherical in cross-sectional shape. Another aspect of the present invention includes inner head surfaces 26, 28 that support bristles and that are complementarily shaped concave and convex, respectively, to hold a tuft of hair in a curved position as the tuft is pulled through the closed heads.

Abstract: A method, computer program product, and infusion pump assembly for determining a first rate-of-change force reading that corresponds to the delivery of a first dose of an infusible fluid via an infusion pump assembly. At least a second rate-of-change force reading is determined that corresponds to the delivery of at least a second dose of the infusible fluid via the infusion pump assembly. An average rate-of-change force reading is determined based, at least in part upon the first rate-of-change force reading and the at least a second rate-of-change force reading.

Abstract: This invention provides a blower design capable of high temperature operation due to use of a self-sustaining cooling scheme through a sealed motor housing in which a cooling circuit can be created, and the use of a thermal barrier across which a temperature gradient may be formed. The thermal barrier may be formed by a thermal choke plate assembly positioned between a hot side and a cold side of the blower to dissipate heat conducted from the hot side. Alternatively, the thermal barrier may be formed by an internal fan ring provided with the blower's rotating assembly to dissipate heat conducted from the blower's impeller. The thermal choke plate assembly and the fan ring may further be used in combination to block heat transfer by all modes between a hot side and a cold side of the blower.

Abstract: A clock comprising concentric rings of slots slits for indicating time by fully illuminating an appropriate one of the slots. Full illumination is propagated from one slot to an adjacent slot by causing all of the slots in a ring of slots to briefly light up sequentially, thus causing a flash of light to propagate around the ring of slots, thus more clearly showing passage of a second, a minute etc as the illumination was switched from the one slot to the adjacent slot.

Abstract: An apparatus for forming a hollow FRP article by internal pressure molding includes a vacuum chamber, a forming die positioned in the vacuum chamber, a vacuum-chamber opening/closing mechanism, a composite-body support device for supporting a composite body without making the composite body come into contact with the forming die in a state where the forming die is opened by the vacuum-chamber opening/closing mechanism, the composite body including an airtight internal-pressure holding tube and a prepreg fitted on said airtight internal-pressure holding tube, an evacuation system for evacuating the vacuum chamber, an internal-pressure supplying device for applying pressure to an inside of the internal-pressure holding tube, and a controller for actuating the vacuum-chamber opening/closing mechanism to clamp the forming die to thereby bring the forming die and the composite body into intimate contact with each other.

Abstract: A three-stroke internal combustion engine completes a complete combustion cycle of exhaust, intake, compression, ignition, and expansion within a single revolution of a crankshaft by a single stroke of a first piston and a single stroke of a second piston within a single cylinder.

Abstract: Device and method for positioning a precision part on a turntable (130). The device (100) comprises at least two distance sensors (121.1, 121.2, 121.3), which operate in a contactless manner and are situated in a previously known configuration to a rotational axis (A1) of the turntable (130). The measurement axes (124.1, 124.2, 124.3) of the distance sensors (121.1, 121.2, 121.3) are radially oriented in the direction of the rotational axis (A1) so that the measurement axes (124.1, 124.2, 124.3) of the distance sensors (121.1, 121.2, 121.3) meet in a virtual measuring point (MV). The distance sensors (121.1, 121.2, 121.3) are connected to analysis electronics (200). Output signals (a.1, a.2, a.3) of the distance sensors (121.1, 121.2, 121.3) may be processed on the basis of the analysis electronics (200), in order to allow coaxial centering of the precision part (11) in relation to the rotational axis (A1) upon placement of the precision part (11) on the turntable (130).

The timing of the actuation of said electrically actuated valves (8, 9) is varied depending on the fluid flow demand.

Abstract: An apparatus for controlling the temperature of a component, which is situated in use in a gas stream, provides a nozzle to create a jet of air at an angle to the gas stream, the jet being directed into the region of the stagnation point of the component so as to control the temperature of the component. The invention is particularly suited to preventing or reducing the formation of ice on vanes of gas turbine engines, but may also be applied to other components, and may equally be used in situations where a component is to be cooled rather than heated.

The signal variables (S2) are predetermined in such a way that the mechanical oscillations are audible and/or tangible.

Abstract: When the fluid flow output of a synthetically commutated hydraulic pump is adapted to a given fluid flow demand, pulsations in the fluid output flow of the synthetically commutated hydraulic pump can occur. To avoid such pressure pulsations, it is suggested, to use a set of pre-calculated actuation patterns for actuating the electrically commutated valves of the synthetically commutated hydraulic pump.

Abstract: To improve the fluid output flow characteristics (14) of a synthetically commutated hydraulic pump (1), it is suggested to use a plurality of different valve (10) actuation strategies. For every fluid flow demand region I to VI a certain actuation strategy is chosen.
