Abstract: A bush assembly comprising a component having a bore, a bush fitted in the bore and having a flange that extends radially outwardly over a surface of the component surrounding the bore, and a seal assembly for sealing the interface between the flange and the surface of the component, wherein the seal assembly includes a seal member and a layer of sealant between the seal member and the interface between the flange and the surface of the component. Also a method for sealing a bush, a kit of parts for forming a bush assembly, and a clamping tool for forming a bush assembly.

Abstract: A glazing unit is provided in which a two part bush is provided such that relative movement between a fastener, a glazing component and a wing skin is permitted, thus avoiding stress concentrations and lowering risk of damage in use.

Abstract: A cross joint (10) is shown that has been formed from a single, flat folded and partially cut sheet. Base panels (12) to (26) are caused to lie horizontally at the base of the joint with the innermost portion of the panel (14) overlapping the innermost portion of the panel (26) and so on around the joint. Panels (34) to (48) extend vertically with panels that include a common fold lying alongside each other and in contact with each other. Panels (56) to (70) lie horizontally at the top with the panel (58) overlapping completely the panel (70) and so on around the structure.

Abstract: There is disclosed a portable printer and a method of selectively printing on any one of a plurality of label rolls housed in the printer, or on a wide roll housed in the printer.

Abstract: An ultrasonic sieving apparatus (10) is described which comprises a de-coupler (18) for enabling a combination of a transducer (T) and a first resonator (16) to be supported with respect to a sieve which includes a separation medium (14) provided in a frame (12) such that vibrations generated by the transducer (T) are transmitted to the separation medium (14) via the first resonator (16). The first resonator (16) is of substantially circular cross-section and has first dimensions. The ultrasonic de-coupler (18) which is also of generally circular cross-section and of second dimensions, is connected to and is concentric with the first resonator (16). In use the de-coupler (18) is attached to a bracket (20) adapted to mount the de-coupler (18) onto the frame (12).

Abstract: A stick-free blood collection system includes elongated inner and outer sheaths and a syringe, including a needle and blood collection tube, mounted with the inner sheath. The inner sheath--and hence the syringe--are axially moveable within the outer sheath. The outer sheath has a small aperture at the distal end thereof to permit passage of the needle through the outer sheath and into the patient. The outer sheath also includes an angled flat portion at the distal end to mount the outer sheath onto the patient in a practical fashion whereby the needle can be telescopically injected into the patient. During operation, the outer sheath is mounted at an angle relative to the surface of the patient, and the needle enters the surface at that angle to draw blood therein. The inner and outer sheaths have mating interconnections which engage when a user twists the inner sheath relative to the outer sheath, thereby preventing axial displacement of one sheath relative to the other sheath.

Abstract: Sieving apparatus has a piezoelectric transducer directly bonded to a grating (100), the transducer comprising a number of piezoelectric elements (1) sandwiched between first and second bodies (2,3 ). The first body (2) is in two parts (2A, 2B) which are releasably secured together (6, 7), one part (2B) being directly bonded (5) to the grating (100). The arrangement allows use of a transducer with different gratings with different parts (2B) of a first body (2) bonded thereto in order to achieve a required operational mode.

Abstract: Sieving apparatus has a piezo-electric transducer (1) directly bonded to a grating (100), the supply to the transducer (1) being controlled by sensing resonance of the grating (100) and any deviation therefrom and controlling the supply to maintain resonance.
