Abstract: 1408556 Coated products DUNLOP HOLDINGS Ltd 11 Oct 1972 [12 Nov 1971] 52578/71 Addition to 1299725 Heading B2E A polyalkylene is bonded to an elastomer by applying to the surface of the polyalkylene an aqueous dispersion of an unmodified polyalkylene which is the same or different from the polyalkylene to which it has first been supplied and thereafter coating the surface with an elastomer. The term "unmodified polyalkylene" defines a polymer of a monoolefinic aliphatic hydrocarbon. The aqueous dispersion is preferably formed by emulsifying a solution of the polyalkylene. The polyalkylene may be a polypropylene or an ethylene/ propylene copolymer in which case it is preferable to use a hydrocarbon mixture to dissolve the polymer. Suitable solvents are listed. The dispersion preferably contains between 0.025 and 25% by weight of the polyalkylene and is preferably heated to a temperature below the melting point of the polyalkylene being treated. Suitable elastomers are natural rubbers and synthetic rubbers such as styrene/ butadiene rubbers, polychloroprene rubbers, polyisoprene rubbers and acrylonitrile rubbers. The elastomer may be vulcanisable or non- vulcanisaible. The base polyalkylene may be in the form of a woven or non-woven fabric, including "spun bonded" material. The polyalkylene may be applied as scrim in a tufted carpet, the elastomer being applied to form a backing.

As shown, Fig.2, the rotating disc has at each radius a different number of slots 3 so that each section of the radiation pattern is modulated at a different frequency. Unit 18 only detects signals at the correct frequency and phase transmitted through the annular bands of slots 3 in the disc 1. Unit 18 may comprise a phosphor screen, photographic film, photo-diode array or television camera tube. The encoding and de-coding disc 1 may be replaced by an apertured cylinder, segmented mirrors or an apertured vibrating plate. The system may be used for a two dimensional image by employing two rotating discs (or their equivalents) with different frequency characteristics moving across the image plane, a linear array of radiation detectors rather than a single detector 10 being used.

Title: Gas turbine engine
IPC: F02C7/05
Filed: 1972-11-15
Abstract: 1427339 Gas turbine engines; ducted fan engines ROLLS-ROYCE (1971) Ltd 14 Nov 1973 [15 Nov 1972] 52796/72 Headings F1G and F1J The invention relates to gas turbine engines and to means for reducing the effects of impact thereon by foreign bodies such as birds during aircraft flight, the invention being described with reference to a ducted fan engine. The fan duct wall shown in Fig. 2 comprises an outer skin 11, an inner skin 12 which comprises a series of rigid panels 17 of acoustic honeycomb structure, and a leading edge portion 6 which is connected to the outer skin 11 by means of an all-round access panel 15 formed of three arcuate portions and which is so formed that it will break upon impact. The outer and inner skins are connected by a series of diaphragms 13 in the form of annular plates. The inner wall comprises also a further panel 17a which is adapted to crush upon impact. An arrangement 19, 20 is provided to limit axial movement. In the event of impact upon the leading edge portion 6, the panel 15 gives and the portion 6 and the panels 17 move axially rearwardly so crushing the panel 17a and causing the diaphragms 13 to be deformed to frusto-conical form - thus the force of the impact is absorbed. The diaphragms 13 may be resiliently deformable such that they recover their initial shape after deflection. In Fig. 3 the ducted fan is driven by shaft 36 supported in a bearing 41, the fan having variable pitch blades movable by control mechanism 35 acting through a drive cone 43 supported in a bearing 42. The rotor fairing cone 30 is slidably supported on an inner cone 33, a resilient bellows member 32 being disposed therebetween. In the event of impact on the fairing cone, the cone moves rearwardly against the compression of the bellows. In Fig. 4, the fan rotor shaft is formed in two parts, the forward part 36a being axially slidable with respect to the rearward part. The forward part 36a is supported in a bearing 41 the outer race 62 of which is connected to a piston 66 slidable in a cylinder 67. The piston is normally located by means of a shear pin 68. The cylinder 67 is formed with a restricted orifice 69. In the event of impact on the rotor fairing cone, the shaft part 36a moves rearwardly breaking the shear pin 68, and compressing the air in the cylinder, the air leaking through the orifice 69. Thus the energy of the impact is absorbed. In a further embodiment, the outer race of the bearing bears against a leaf-spring which absorbs the energy upon axial movement of the shaft and bearing resulting from impact.

The compressed air is supplied via a muff 26, groove 27 and passages 28 to both chambers 18. The pistons 20 have vanes 21 at their adjacent ends. The device may have only one piston, and powder may be used in place of shot. The invention can also be applied to a fluid coupling using oil, and oil can be used instead of compressed air to move the pistons 20. The centrifugal force of the driving medium aids the movement of pistons by the springs 24.
