Title: A device for the condensing of water vapour
IPC: B01D5/00
Filed: 1982-04-23
Abstract: A device for the condensing of water vapour comprises an open topped box (1) which is hermetically sealed by a cover (9). The box (1) is provided with a lateral inlet (2) for receiving air containing water vapour, and is provided with an air outlet at the opposite end of the box. The base wall of the box provides a plurality of upward projections (3) of narrow prismatic shape, whereas the top wall of the cover (9) has a plurality of corresponding downward projections (12), which extend between the upward projections (3) to define a labyrinth path for the air flow between the inlet (2) and the outlet from the box (1). Water vapour thus becomes condensed by contact with the projections (3 and 12) and collects in the base of the box (1). The base of the box is inclined at an angle (14) towards the inlet (2) and small drainage channels bypassing the projections (3) enable the condensed water to flow back and escape through the inlet (2). <IMAGE>

Title: Radio frequency heating apparatus
Inventor: GRAHAM JOHN FOSTER
IPC: D06B19/00
Filed: 1980-02-27
Abstract: In dyeing keratinous fibres, such as wool, by impregnating the fibres with aqueous compositions containing dyes, followed by storage in the moist condition, a higher level of fixation, enabling heavier shades to be obtained with cheaper dyes, can be achieved by raising the temperature of the stored fibres by means of radio frequency heating. The storage temperature is preferably between 40 DEG  and 80 DEG  C., which usually requires about 0.05 kw hour/kg fibres. Acid, milling, chrome and premetallized dyes can be used, as well as reactive dyes and substantive optical brighteners. The fibres are cuttled into an insulated plastics material cart located between a pair of electrodes in an r.f. chamber. One electrode is fixed and the other is adjustable so that the r.f. load acting on the fibres may be set at a desired value.

Title: Apparatus and method for aseptically filling flexible containers
Inventor: SCHOLLE WILLIAM R
IPC: B65B55/02
Filed: 1983-01-31
Abstract: An apparatus for aseptically filling premanufactured, presterilized, flexible containers, connected in a continuous web, includes an elongate chamber with an inlet 20 for receiving empty containers seriatim, and an outlet 21 for dispensing filled containers seriatim. The inlet and outlet have respective flexible seals 64; 66, 67 for sealing to the surface of the containers and chamber is segregated into an entry chamber 70 and a filling chamber 68, with a drying chamber 72 therebetween. The containers pass through a liquid lock 62 between the entry and drying chambers to coat the exterior of the containers with the sterilizing agent as they are serially advanced through the chambers. This liquid lock also provides an aseptic barrier between the inlet and the drying chamber. A source of sterile air is input to the filling chamber 68 to maintain a positive pressure therein, and thus, prevent entry of contaminants. This heated sterile air flows from the filling chamber 68 to the drying chamber 72 to dry the containers after they have been coated with the sterilizing agent. The length of time the empty containers are exposed to the atmosphere, and thus, the amount of contamination on the exterior of the containers is reduced by connecting the sealed overwrap bag 120, in which the containers are presterilized, to the inlet 20, thus forming a relatively sterile tunnel through which the containers are fed to the inlet. <IMAGE>
