  • Patent number: 10639002
    Abstract: An embryo transfer catheter or other medical device has a shaft extruded with two layers. The outer layer is relatively thick and contains gas bubbles sufficient to increase the visibility of the catheter under ultrasound observation but with a density that allows material within the catheter to be viewed by the eye. The inner layer is relatively thin and is free of bubbles so that it provides a smooth bore to the catheter.

  • Publication number: 20140209572
    Abstract: There is provided a contact device (10) for application to an opposing surface (46;50) in use. The contact device comprises a support (12) and a plurality of contact members (14) aligned along the support. Each contact member has an end portion (15) spaced from the support and is independently resiliently mounted to the support such that the end portions (15) can conform to the opposing surface (46;50) in use and thereby provide a seal there-against. The contact members and/or support and may be planar in form and may be cut from a sheet metal material. The contact device may serve as a gas shield or a support jig or clamp device.

  • Patent number: 7886613
    Abstract: A method for detecting the strain applied to a transmission chain includes positioning a strain gauge on an inwardly-facing surface of a first of a pair of opposed outer link plates, spacing the inwardly-facing surface of the first outer link plate from an outwardly-facing surface of a first of a pair of opposed inner link plates facing the first outer link plate, connecting the strain gauge into a bridge network and an electric circuit, and using an output of the electric circuit to determine the strain applied to the chain.

  • Publication number: 20110028256
    Abstract: A chain such as a roller bush chain comprising a plurality of interconnected chain link members (2,3) is provided with a wiper element (9) that extends at the interface between overlapping portions of the link members. The wiper may be a formation defined on one of the link members or a bush (8) of the chain or may be a separate component between the link members. The wiper has a wiping edge that in use moves relative to a surface of at least one of the members and serves to wipe that surface clean of deposits or debris so as to allow lubricant to penetrate to the bearing between the pin and link members or bush and to reduce the risk of wear.

  • Patent number: 7634949
    Abstract: A transmission chain comprises has a data collection device mounted on at least one of the links. A strain gauge sensor is mounted on the inwardly facing surface of an outer link plate symmetrically about a centre link thereof and measures the strain on the link plate. The measurements are compared to a threshold and a visual indicator mounted on the chain is activated if the threshold is exceeded. The data collection device can be controlled by a first controller device that simply switches it between a quiescent state to an overload detecting state or a second controller type can be used for data-logging and analysis.

  • Publication number: 20070031604
    Abstract: A method of decorating an article, the method comprising mixing a thermochromic ink with a transparent lacquer, applying the mixture on to part or all of the surface of an article, once the mixture is set, applying a second layer of dishwasher proof transparent lacquer.

  • Publication number: 20050215373
    Abstract: A power transmission chain has a plurality of overlapping inner and outer link plates interconnected by transverse pins that pass through aligned apertures in the overlapping plates. The pins are square or rectangular in cross section and one of the planar surfaces on each pin is designed to bear against an arcuate bearing surface defining part of the aperture in the inner link plate. The outer link plate is has a square or rectangular aperture that is a friction fit with the pin. The arrangement provide an articulating joint in which there is rolling contact between the planar and arcuate bearing surfaces during articulation of the first link member on the pin and thus reduces noise and wear.

  • Patent number: 6851546
    Abstract: A method and apparatus for automatically monitoring the wear of a chain when in operation in a chain drive assembly. First and second markers are applied to the chain at a predetermined distance apart. A first sensor is disposed adjacent to the chain to coincide with the position of the first marker. A second sensor is disposed adjacent to the chain to coincide with the position of the second marker. The sensors generate signals in response to the detection of the markers. When the chain drive is operated the first and second sensors are initially triggered substantially simultaneously by said first and second markers respectively. After the chain extends through wear elongation is identified by detecting a time delay between the triggering of the first and second sensors by the respective markers. One of the sensors is then moved to a position where substantially simultaneous triggering of the sensors by the markers can be resumed.

  • Patent number: 4250761
    Abstract: In computerized tomographic apparatus having an intermittent rotational motion the scanning time can be reduced by increasing the rotation speed. However this can result in excessive forces being transmitted to the stationary mainframe of the equipment. The invention reduces that problem by balancing the forces of rotation at least in part by appropriately placed counter masses. In one embodiment the counter masses rotate and properly balance the forces. In another embodiment they move linearly and delay the application of the forces to the mainframe and transmit the delayed forces over a longer period.
