Title: Improvements in or relating to the continuous treating of textile webs
Inventor: KUSTERS EDUARD
IPC: F26B13/00
Filed: 1967-11-21
Abstract: 1,200,117. Textile treating apparatus. E. KUSTERS. 21 Nov., 1967 [1 June, 1967], No. 52817/67. Heading D1L. A method for the continuous treatment of textile webs comprises continuously feeding the web into a treatment chamber onto a support surface having at least one full turn, maintaining the material inlet at a level different from the material outlet and continuously moving the material over the support surface in such a manner that the material takes a helical passage through the treatment chamber. The support surface may be a series of concentric rails 9, 10 one end of which is at a higher level than the other, alternate rails 9 or 10 being connected to means 13, 14 for forming a lifting mechanism. The web 15 is fed onto the support surface over a roll 17 and may be overlapped a predetermined number of times before being taken out of the chamber. If desired the rail support surface may be in the form of a helix within the treatment chamber and can be either rotated, oscillated or vibrated whilst the web is moved over the surface. Seals at the entry and exit of the chamber may be provided by the nip of a pair of rolls. Also if desired the web may be fed on to the support in folds. A plurality of webs may be simultaneously treated by providing several support surfaces one above the other in a treatment chamber.

The combination of a liquid fuel burner 3 having a spray nozzle 3a and a control system therefor includes a fuel pump 2 in a fuel line 12 leading to the burner 3, a burner valve 4 including a needle plunger 7 acting in co-operation with a seat 8 disposed in the burner 3, the plunger 7 being biased towards the seat 8 to prevent fuel under a predetermined minimum pressure flowing to the burner nozzle, 3a, a fuel by-pass line 13 for by-passing the burner valve 4 connected into the fuel line 12 between the pump 2 and the burner valve 4, and in the by-pass line 13, a by-pass valve 20 adapted to close and open upon respective energization and de-energization of the fuel pump 2 whereby upon the fuel pump 2 being de-energized, the pressure of fuel on the burner valve 4 is relieved through the by-pass valve 20. The fuel flows from the by-pass valve 20 through the by-pass line 13 back to a reservoir 1. The by-pass valve 20 includes a solenoid actuated needle plunger 21 co-operable with a seat 23 and the needle plunger 21 is movable to close the valve 20 upon energizaton of the fuel pump 2 which is driven by an electric motor 5 in the same electrical circuit as the solenoid winding 25: the needle plunger 21 is biased to close the valve 20 by a spring 21.

Abstract: 1333111 Recording images MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 2 Dec 1970 [2 Dec 1969 (2)] 57351/70 Heading H1K A latent record of an image is formed by applying an electric field in a pattern corresponding to the image to a body of material comprising insulating material including conductive particles dispersed therein whereby regions of the body subjected to the field are caused to change from a first high resistance state to a second low resistance state and to be retained in the second state after removal of the field thereby to provide the record. The body may comprise a dispersion of Ag, Fe, Cu, carbon black or graphite in chlorinated natural rubber, chlorinated polyethylene, a mixture of polystyrene and chlorinated paraffin, PVC, epoxy resin, polyamide, polyester or polyacetal. The material exhibits three resistivity states, Fig. 2, a high resistance state 18, low resistance state 20 and a memory state 23. The memory state 23 is retained after repeated cycles of increasing and decreasing voltage or the absence of an applied voltage. The material is restored to resistance state 18 by heating to above the glass transition temperature of the resin. In one embodiment (Fig. 1, not shown) a latent image comprising portions switched to the memory state, is traced out on the material (10) using a movable electrode pen (15). The material is subsequently charged electrostatically, the charge leaking away in an imagewise manner whilst the remaining charge is developed with electroscopic particles. In another embodiment (Fig. 3, not shown) the electrode used is in the form of a multiplicity of dot electrodes (25) each in series connection with a resistor (26) together with a common electrode (27) but insulated from one another by insulating material (28). The latent image is formed either by selecting appropriate dot electrodes or forming the electrode into the desired image. In an alternative embodiment (Figs. 4 and 5, not shown) a photoconductive layer (35), e.g. polyvinyl carbazole and a sensitizer is interposed between the electrode and the memory material. The electrode may be Nesa glass, or aluminium foil, graphite in phenolic resin or an aluminium grid vacuum deposited on Nesa glass.
