Abstract: Surface-moist bulk foods tend to stick and form lumps when frozen in belt-type freezers. This results in product damage. In order to prevent this, an immersion freezer (9) is disposed at the inlet aperture (8) of the belt-type freezer, in which the food is separated and incipiently frozen. The vaporised refrigerant is extracted in co-current through the outlet aperture (6) of the belt-type freezer. The belt-type freezer can be designed in the form of a longitudinal tunnel, helical belt tunnel or multi-level tunnel. <IMAGE>

Abstract: The device comprises a source (1) of electrically charged elementary particles, emitting a beam (2) of particles which is split into two partial beams (4, 5) sent onto different paths. A difference in velocity and hence in wavelength is generated between the two partial beams. The two partial beams are recombined into a single beam (14) and their beat is detected as an electrical signal. The velocity difference can be generated by a voltage generator (6b) or by the output voltage of an antenna.

Abstract: A microwave resonant cavity (10) for a spectroscopic light source includes a housing (12) having therein a chamber (26) formed by side walls (14, 16) and a cylindri­cal outer wall (18). The side walls have aligned openings (22, 24) therethrough which are on the longitudinal axis of the outer wall (18). A refractory tube (34) which is adapted to contain a gaseous plasma extends through the aligned openings (22, 24) and across the chamber (26) in the housing. A coupling loop is electrically coupled to a side wall (16) of the chamber (26) within a portion (32) of the chamber (26) and is connected to a coaxial connec­tor (67, 70) which extends through the outer wall (18) of the housing (12) to deliver microwave power to the chamber (26). One end of the refractory tube (34) extends into an exhaust chamber (48) mounted at one side wall (16) of the housing. The exhaust chamber (48) has an exhaust passage (52, 54) to permit exhausting of gas. Means (57 - 61) extend into the exhaust chamber (48) for extracting a portion of the gaseous plasma effluent from the end of the refractory tube (34) into a mass spectrometer.

Abstract: In a liquid handling station taking up and dispensing liquid through one or a plurality of pipettes each having a syringe and a respective nozzle, it is customary to fit the nozzle(s) with a disposable pipette tip(s) which is replaced between samples to avoid cross-contamination. There are difficulties in reliably fitting and sealing these pipette tips onto the nozzles. The present invention simplifies the fitting and sealing of pipette tips onto nozzles by forming each nozzle with an annular groove having a controllably variable axial width. An elastomeric O-ring seal is fitted in each annular groove. The nozzle and its fitted O-ring seal is inserted into a pipette tip, and then the axial width of the annular groove is controllably reduced to cause a circumferential expansion of the O-ring seal. The nozzle and the pipette tip become mechanically and sealingly attached without the pipette tip having to be force-fitted onto the nozzle as was previously necessary. The pipette tip is subsequently detached by controllably increasing the axial width of the annular groove to allow a circumferential contraction of the O-ring seal. Manufacturing tolerances in the pipette tips do not have an adverse effect on the resultant nozzle/tip seal.

Abstract: A sputtering apparatus for coating a substrate comprising a first electrode (14) for supporting a suitable target material and a second electrode (16′) for supporting a sub­strate, upon which a coating is deposited. A source (22) of RF power is connected to impose an RF voltage across the electrodes to produce a glow discharge in the space between the electrodes. A shield (20) is provided surrounding the peripheral edges and the back of the second electrode, and this shield is spaced a substantial distance from the back of the electrode. Electrical insulating material is placed in the space between the shield and the back of the second electrode with a small gap between the electrical insulating material and the shield. The configuration of the shield, the insulating material, and the second electrode eliminates spurious sputtering from the peripheral and back regions of the second electrode so that very high power levels can be achieved and sputtering can be done very efficiently at high sputtering rates.

Abstract: The method of generating an image of objects in a three dimensional space for display on a two dimensional pixel array averages N renditions of the image, with each rendition having a sub-pixel offset from the previous rendition, to produce an anti-alias filtering effect. The N sub-pixel offsets are arranged to produce a basic array which ensures N times oversampling of a selected class or classes of image feature. For example, to give good antialias filtering of edges closely aligned with the x-y axes of the pixel array, the offsets are chosen to ensure bisection of the pixel area (A) at N points in each of x and y.
