Abstract:
An adjustable support assembly for use in a chair has a mounting member 603, a support 605 for supporting part of the body of a chair occupant, and a carrier 611 slidably carrying the support 605. The support has a plurality of engagement features 621 and the carrier has an engagement member 615 that is selectively engageable with the engagement features to enable the support to be selectively positioned relative to the carrier at a plurality of positions. A biasing arrangement 607 operatively connects the carrier 611 to the mounting member 603 and forwardly biases the carrier 611 and support 605. The engagement between the engagement member 615 and an engaged engagement feature 621 increases upon application of rearward force to the support.
Abstract:
A system (100) for determining a property of an object (106) comprises an inducing arrangement (102), a detector (104) and a processor. The inducing arrangement (102) is configured to generate an impulse of fluid and for directing the impulse of fluid towards the object to induce a physical vibration of the object (106). The inducing arrangement (102) does not contact the object 106 when inducing the physical vibration of the object (106). The detector (104) is configured to detect the physical vibration of the object (106). The detector (104) does not contact the object 106 when detecting the physical vibration of the object (106). The processor is coupled to the detector (104) for determining the property of the object (106) based on at least the detected physical vibration.
Abstract:
A ratchet device 1 for a strap has a body 105 having a side member 109, and a spool 119 having a side 119a rotatably supported by the side member and a ratchet wheel 121 fixed thereto. The body has a member 161 moveable between an open position in which the other side 119b of the spool is exposed to enable a strap to be laterally loaded into the spool 119 from the exposed side of the spool and laterally unloaded from the spool, and a closed position in which said lateral loading and unloading are prevented.
Abstract:
A device (100) for forming products has a plurality of moulds (6) arranged generally in a row R- Each mould has a cavity for receiving a liquid mixture, the cavity being open at the bottom to allow the formed product to be removed from the cavity. A line (7) is operatively connected to the moulds, the line extending in a direction generally parallel to the row R of moulds. The moulds (6) and the line (7) are arranged such that as the line is lifted from one end, the moulds are Lifted successively along the row. The device may have a locating frame (20) having a plurality of rails (19,23) adapted to guide the location of the moulds (6).
Abstract:
A method and apparatus for detecting ultrasound vibrations of a subject (5) is disclosed. The method comprises passing a modulated beam (6) from a vibrating subject through a resonant medium (7). The beam (4) has a carrier frequency component and two major sideband frequency components. The resonant medium (7) imparts a phase shift on the carrier frequency component and passes the two major sideband frequency components to output an amplitude modulated signal. The ultrasound vibrations of the subject (5) can be detected from the amplitude modulated signal.
Abstract:
A method of, and apparatus for, profiling a tube to form at least one profiled product having a first open end and a second open end. The tube (30) is supported on a support (19) which supports the tube along at least a substantial part of the length of the tube corresponding to the product(s) to be formed. At least a portion of the tube is heated to form at least one heat-softened portion of the tube in the region(s) corresponding to the product(s) to be formed. A fluid pressure change (28) is applied to the region(s) of the tube corresponding to the product(s) to be formed to form at least one profiled product having a first open end, a second open end, and a predetermined shape with one or more three dimensional profile features.
Abstract:
A reaction vessel holder (120) receives a reaction vessel (110). The reaction vessel (110) has a portion that is substantially optically transparent to light of a first range of wavelengths. The reaction vessel holder (120) comprises a body having a high thermal conductivity that is thermally coupled to and supports the reaction vessel (120). The body is further thermally coupled to a thermal device (130) for heating or cooling the reaction vessel holder (120) and thereby the reaction vessel (110). The body comprises a transparent portion that is substantially optically transparent to the light of the first range of wavelengths. The optically transparent portion of the reaction vessel (110) faces the transparent portion of the body such that light of the first range of wavelengths to and/or from the sample in the reaction vessel (120) can pass through the transparent portion.
Abstract:
A LED array (1) has an assembly of LED packages (2). The LED packages (2) are mounted to a substructure having circuitry and a heat transfer plate (4). Each LED package 2 has electrical connection terminals (22) and a thermal connection pad (24), with the electrical terminals (22) electrically connected to respective circuit conductors of the circuitry and the thermal pads (24) connected to the heat transfer plate (4) by respective thermally conductive connections. At least one of the LED packages (2) is tilted at an angle relative to an adjacent portion of the substructure.
Abstract:
A device (100) for removal of marking(s) from a road surface, adapted for attachment to a road vehicle with a collection system. The device has a frame or housing (10), a riding member (11), and a mounting structure (110) for attachment of the device to the road vehicle. The mounting structure is adapted for selectively lifting and supporting the frame or housing at an elevated position clear of the road marking(s) and the road surface, or lowering the frame or housing to a deployed position in which the frame or housing is supported by the riding member which is then in contact with the road surface. A tool (30, 40) that presents an impact surface is driven by a prime mover to impact the impact surface against the marking(s) on the road surface when the frame or housing is in the deployed position and over the marking(s).
