Title: Improvements relating to Microporous Flexible Sheet Materials.
Inventor: CUNNINGHAM VICTOR RALPH
IPC: C08J9/24
Filed: 1966-03-07
Abstract: 1,187,032. Coating. PORVAIR Ltd. 7 March, 1967 [7 March, 1966; 11 Jan., 1967], Nos. 10528/67 and 1610/67. Divided out of 1186342. Heading B2E. [Also in Division C3] Flexible sheet material comprises strength imparting microporous, elastomeric, polyurethane material free from preformed fibrous sheet material having at least one integral fibrous surface resembling a suede leather or the flesh surface of natural leather. The sheet material is made by forming a spreadable mixture comprising a solution of a film forming plastics material in a solvent, forming a continuous layer of the mixture on a temporary support formed of sintered particles treating the layer on the support with a coagulating liquid which is a non-solvent for the polymer but is at least partially miscible with the solvent, so as to coagulate the polymer into a sheet, and washing with fresh coagulating liquid or continuing the treatment until all the solvent has been removed, drying the resultant sheet material and stripping it from the temporary support. The support may be a sheet of sintered granulated plastics material such as high density polyethylene, or may be formed by a sintered layer of granules of polymeric plastics material on a smooth metal surface. The support may be first wetted with a solution of a substance which is soluble in the coagulating liquid e.g. an aqueous solution of sodium chloride so as to be left with a coating of the substance which subsequently dissolved by the coagulating liquid e.g. water thereby facilitating the stripping of the sheet material from the support. In example 1 a layer of a solution of a polyester-based polyurethane in N,N-dimethyl formamide is doctor knife coated onto a smooth surface of a sintered high density polyethylene layer on a metal surface, and the material immersed in and washed with water at 70‹ Centigrade, dried and the layer stripped from the temporary support. The material can be used as suede leather in clothing or as a shoe upper, glove and upholstery materials. In example 2 the product of example 1 is coated with a solution of a polyurethane in dimethylcyclohexanone containing sodium chloride as removable filler, and then with a surface coating of a solution of a polyurethane in dimethyl formamide also containing sodium chloride and a pigment. The composite sheet is immersed in water at 20‹C. and then washed in water at 80‹C. before drying at 100‹C. and stripping from the temporary support. In example 3 a removable filler e.g. sodium chloride is also included in the composition for making the vapour permeable sheet material.

Title: Improvements in or relating to electron discharge apparatus

IPC: H01J23/42
Filed: 1948-01-27
Abstract: 680,796. Travelling wave tubes. STANDARD TELEPHONES CABLES, Ltd. Jan. 21, 1949 [Jan. 27, 1948], No. 2436/48. Class 39(i) [Also in Group XL(b)] A travelling wave amplifier tube of the helix type is coupled to an input waveguide by a doorknob probe; the output coupling may be similar. In one form, Fig. 1, the input and preferably also the output ends of the helix 3 are coupled to a waveguide 6 or waveguides without distortion of the end turns of the helix 3 by means of a tubular probe 5 connected to the helix by a straight rod or wire 4 and co-operating with a tapered " doorknob probe 7 secured to a wall of the guide 6. Probe 7 and flange member 8, together with probe 5 forms a "quarter wave sleeve," i.e. of an odd number (including unity) of quarter wavelengths long at the mean frequency to be amplified. The input and output couplings may both be as shown; in some forms, the inner probe at the output end may be a solid block formed with a cup-shaped depression and serving as the final collector. The electron gun 10 is designed for magnetic focusing produced by a coil wound around glass bulb 2 and an auxiliary coil wound around brass cylinder 9. The helix 3 may be supported on internal projections of the glass envelope 1. In a modification, Figs. 2, 3 (not shown), a single probe member only is used instead of the two members 5, 7, and at the input end of the device is formed with feathered flanges for sealing to glass envelope portions on either side; at the output end it has only one feathered flange for sealing to a single glass envelope portion and has a cup-shaped depression and serves as the final collector. In a further modification using only a single probe member, Fig. 4, the probe 20 is of sheet metal and glass envelope portions 21, 22 are sealed thereto on either side. The electron gun is brought up inside probe 20 which may also form the final gun anode so that electrostatic focusing at the beam entry to the helix 3 may be had. In a further modification, Fig. 5, also using a single probe, the latter comprises a metal disc 23 and resilient tapered metal part 26 sprung over the disc. The disc 23 may serve as the final gun anode. In all forms the probe projects approximately halfway across the waveguide and the helix 3 projects slightly into the waveguide at the opposite wall thereof. The characteristic impedance of the probe is made to match the waveguide impedance as nearly as possible at the centre of the band to be amplified. A prior art travelling wave amplifier is referred to in which the end turns of the helix are opened out and connected to a straight conductor formed as a hollow stub which co-operates with a flange on the waveguide wall to form a quarter wave sleeve.
