Title: Sterilising packaging material
Inventor: REITER MICHAEL
IPC: A61L2/06
Filed: 1986-11-13
Abstract: Packaging material is sterilised by atomizing hydrogen peroxide, mixing it with compressed air, vapourizing the mixture, setting it in turbulence and blowing it on to the surface of the material so that the vapour is condensed, the turbulence being produced by imparting a rotary movement to the mixture along a central axis and guiding a liquid boundary layer produced by the centrifugal action of the rotary flow at least partially in the opposite direction to the main flow, so that a very good vaporization capacity is achieved. The rotary flow movement may be imparted to the mixture by swirl bodies (19, 21) and coil spring inserts (22, 23) inserted alternately therewith inside a spray pipe (18) and the liquid which has not yet vaporized is given a flow direction in opposition to that of the main stream of the mixture and consequently a long residence time of the liquid on the pipe wall of the spray pipe (18) is achieved. …<IMAGE>…

Abstract: Apparatus for orienting spoons (8) having a flat handle (9) and a shorter bowl (11) inclined at an obtuse angle to the handle (9) comprises resilient surfaced feed rollers (14) to which spoons (8) are delivered in succession. Spoons leaving the rollers (14) handle first are rotated by deflection means (20) through 180 DEG  while spoons (8) with the bowl (11) leading do not engage the deflection means (20) and are thus undeflected. The spoons (8) therefore enter a guide channel (21, 22, 24) with bowls (11) leading and are delivered to a nip between resilient surfaced alignment rollers (26) which grip the spoons (8) and feed them downstream into the one of two outlets (30, 32) depending on which way the bowl (11) is facing. One of the outlets (32) rotates the spoons entering it through 180 DEG  so that spoons are delivered to a delivery zone in the same orientation irrespective of which outlet they pass through. <IMAGE>

Title: Laminate
Inventor: MOUNTAIN PAUL RONALD
IPC: B32B3/02
Filed: 1989-08-23
Abstract: A laminate has layers 2 of contrasting appearance and a finished face 4 oblique to the layers. The laminate is preferably of wood and its layers are of contrasting appearance. Contrasting appearance may be achieved by finishing steps which may include dyeing, staining, bleaching and sanding. The different layers present different aspects of grain on the finished face, and as a result the finishing steps may give rise to differential effects on the finishes face. The layers are jointed together by an adhesive which gives rise to a discrete line between the layers, as seen on the finished face. Composite articles are described in which a plurality of laminates are secured together to enclose a space. Methods for the manufacture of such laminates and composite articles are described. <IMAGE>
