Title: Modified polytetrafluoroethylene coated heat resistant fabric
IPC: D06M11/17
Filed: 1954-05-25
Abstract: An aqueous suspension comprising polytetrafluoroethylene and particulate sodium aluminium fluoride (cryolite), wherein the cryolite content is 5-40 per cent, preferably 10-20 per cent, of the combined weight of cryolite and polytetrafluoroethylene, is used to coat fabrics.  A dispersion of cryolite in water with a polyethylene glycol ether of an alkylated phenol as dispersing agent is mixed with a dispersion of polytetrafluoroethylene with the same dispersing agent, and two dip coatings of the mixture are applied to the fabric with heating to at least 621 DEG  F. to fuse the polytetrafluoroethylene.  Specification 631,504 is referred to.ALSO:Woven or non-woven fabric of glass, asbestos or heat-treated polyacrylonitrile fibres is impregnated with an aqueous suspension comprising polytetrafluoroethylene and particulate sodium aluminium fluoride (cryolite), wherein the cryolite content is 5-40 per cent, preferably 10-20 per cent, of the combined weight of cryolite and polytetrafluoroethylene, and the fabric is heated to at least 621 DEG F. to fuse the polytetrafluoroethylene.  The resistance of the fabric to tearing is thus improved.  A dispersion of cryolite in water with a polyethylene glycol ether of an alkylated phenol as dispersing agent may be mixed with a dispersion of polytetrafluoroethylene with the same dispersing agent, and two applications of the mixture made to the fabric with heating to at least 621 DEG F. between each application.  The applied material may be insufficient to fill all the interstices of the fabric.  Specification 631,504 [Group IV(a)] is referred to.

Patent GB-817306-A (GB)
Title: Improvements in or relating to slot radiators
IPC: H01Q21/00
Filed: 1957-05-21
Abstract: 817,306. Aerials. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. May 21, 1957 [May 26, 1956], No. 16084/57. Class 40 (7). The invention relates to aerials consisting of one or more shunt arranged slots in a rectangular waveguide. According to the invention a small diameter rod is introduced into the guide to act as an energy reflector to increase the amount of energy radiated by the slot. Where the slot, occurs in a symmetrical position at a T-junction, two rods are used. In a first embodiment shown in theoretical plan view in Fig. 3, and in broken away perspective in Fig. 4, the slot 31 is cut in the top broad face 32 of the waveguide 42 with its mid-line 36 a distance 35 from the centre line 33 of the guide face. If energy is to be supplied along the guide in the direction 37 a cylindrical metal rod 39 is placed beyond the slot a distance 38, on the same side of the centre line 33 as the slot, and a distance 40 therefrom. The length 34 of the slot may be about half of the free space wavelength and the distance 38 a quarter of the wavelength in the guide. The drawings include a graph relating the proportion of the energy radiated by the slot and the distance 40 and a further graph relating, the distances 40 and 35 for resonance in a particular example. Once such graphs have been determined experimentally for a given set of conditions the design of an array of shunt slots along the guide may be readily carried out. Such an array may comprise slots on both sides of the centre line 33, if desired. As the slot and rod introduce discontinuities into the guide it is desirable to introduce means such as the plate 41 to prevent an increase in the standing wave ratio. Where an array of slots in a guide 93-94 is fed with energy at an intermediate point as at a T- junction by guide 91 a slot 97 may be cut on the centre line of the broad face of the guide 93-94. This slot is also made symmetrical with respect to the centre line 99 of the guide 91. Two rods 101 and 102 are provided arranged one on each side of the line 99 to control the radiation from the slot. The exact positioning to obtain the required proportion of the energy radiated is determined by experiment. A wedge-shaped metal block 103 is used to correct for discontinuities caused by the slot and rods.
