IPC: F02C7/06
Filed: 1976-12-17
Abstract: The invention relates to a gas turbine engine for propelling projectiles. The engine 10, whose shaft 23 carries a compressor 12 to 18 and a turbine 20-21 separated by a combustion chamber 19, is surrounded by a thin casing 29 mounted coaxially, and with spacing, in a stronger casing 30 forming the projectile outer casing. The two casings are connected upstream by three mounting bolts 31 and held spaced apart from one another by excess pressure of intermediate air, the irregularities in coaxiality arising during operation being damped by two series of dampers 32 and 33, arranged at the downstream part of the outer casing 30 and inner casing 29 respectively, coming into contact. The drive shaft 23 may further contain an inflammable load whose gaseous discharge actuates an auxiliary starting turbine. The device gives a significant weight saving and greater operational flexibility. <IMAGE>

A method of making footwear includes the steps of joining by adhesive or injection moulding a sole to an upper of rough, e.g. unfinished, material to which the sole can be directly joined without further processing, and applying to the part of the upper which is not covered by the sole in the finished article at least one covering layer which provides the finish to the upper material. The layer(s) may be applied to the lasted upper before or after the sole is joined to the upper. The upper may be (i) a conventionally lasted upper of unfinished, e.g. fallow, leather, (ii) a textile, e.g. a woven or knitted fabric which is applied in tubular form 2 (Fig. 1) over a last 1, the ends being closed by horizontal seams 5, 6 which are folded under in the direction of arrows 9, 10; alternatvely the end seams may be vertical and folded sideways (iii) a foil of shrinkable synthetic material which may be applied to the last in tubular form and caused to shrink to the shape of the last by the application of heat, or (iv) a polyurethane foam material. The finishing layer is preferably a coating or coatings of polyurethane. The coating may be applied to the lasted upper prior to soling by spraying using a template or mask to cover the area to which the sole is attached. Alternatively the coating may be applied to the upper by spraying after the sole has been moulded and while the sole is still in the mould. The coating may also be applied after the sole has been removed from the mould by (i) an electrostatic spray process (Fig. 5) which directs the spray 24 onto the upper only or (ii) by dipping the entire shoe into the coating material, the sole having been covered by a release agent so that the coating can easily be removed from the sole, e.g. by brushing.

Each disc filter 10 comprises segments 12 in communication with ducts 15 extending lengthwise of the rotary shaft 11. At one end of the shaft 11 is a stationary member 19 having ports 20, 22, 21, ports 20 and 21 being connected with vacuum means (not shown) and port 22 with compressed gas or pressurised water source (not shown). As the drum rotates the ducts coincide with ports 20, 22, 21. Chutes 18 positioned between discs 10 receive removed filter cake. Some of the chutes may be provided with pivotable flaps for deflecting removed filtered cake back in to bath 17. The removed filter cake may be discharged to a conveyor. A piston may be mounted in each sector, the piston being operated to apply pressure to remove the filter cakes from the sector. Water may be sprayed onto the outer surfaces of the discs to aid removal of the filter cake. In a rotary drum filter a chute receiving removed filter cake may be provided with gaps to return filter cake to the bath. The chute may be adjustable along the length of the bath.

Abstract: 1,199,589. Tubular heat exchangers. E. I. DU PONT DE NEMOURS & CO. 27 Nov., 1967 [30 Nov., 1966], No. 53947/67. Heading F4S. In a heat exchange process between two fluids, a first fluid flows through a bundle of elongated hollow flexible, thin-walled, small diameter tubes 11 formed of an inorganic polymeric material joined to a header wall (not shown) at each end of an elongated hollow casing 1 from a supply to an exhaust conduit 8, 9. The tubes are spaced from the interior wall of the casing to provide a first flow path for the second fluid from an inlet 4 between the casing and the tube bundle and a second flow path for the second fluid which passes through the space between the tubes within the bundle to an outlet 5. Presettable annular baffles 13 are spaced along the bundle in engagement with the interior of the casing and a foraminous sleeve 10 encasing the tube bundle at predetermined points to control, along the length of the bundle, the proportion of second fluid passing along the second flow path relative to that in the first path according to the total amount of second fluid handled per unit time and the desired total amount of heat transferred per unit time. The tubes are positioned relative to one another and restrained against the force of the inwardly and outwardly moving fluid by bonding the tubes to flexible, narrow strip or tape which is interleaved between the tubes in a predetermined pattern in a substantially transversely-extending section across the bundle.
Patent GB-540620-A (GB)
Abstract: 540,620. Bearings. ELLIOTT BROS. (LONDON), Ltd., and HARBEN, D. C. April 22, 1940, No. 7263. [Class 12 (i)] [Also in Groups XXXVI and XXXVII] In a measuring instrument or relay of the permanent magnet moving coil type having the magnet located wholly externally of the coil, the coil is mounted on pivots each comprising a blunt-nosed pin working in a metal cup, and the magnet is designed to produce a flux density in the gap of the order of 3,000 Gauss. This high flux density produces a torque sufficiently high to permit the use of bearings having a higher frictional torque than the normal jewelled type. The ammeter or voltmeter shown is intended for ships bulkhead mounting and is bolted to the bulkhead through flanges 1 on the front vertical wall 2 of the casing 3. The scale 5 is read through a window 4 of non-vitreous material such as a cellulose acetate material. The magnet assembly and moving parts are mounted on a base plate 6 which is supported on pillars 7 on the base of the casing. The permanent magent consists of a cast rectangular block 8 of aluminiumnickel or aluminium-nickel-cobalt steel and is clamped, by nuts 9 on a bolt 10 passing centrally through the block 8, between'the ends of a pair of parallel mild steel side plates 11 carrying pole pieces 12. The moving coil is wound on an aluminium former 27 to each end of which is secured an aluminium plate 26, Fig. 3 with a central boss 25 into which is screwed a blunt steel pivot pin 23. The upper and lower bearings are mounted in bridge pieces 17 supported through insulating washers on pillars screwed into the upper and lower surfaces of the pole pieces 12. Each bearing consists of a steel screw 18 threaded through a mounting bush 19 which is fitted into a central hole in the bridge piece. 'The inner end of this screw is formed with a deep conical recess 20 whose apex is rounded to form a spherical seating for the spherical ends of the pivot pin 23. The pivot pin 23 may be 1 mm. in diameter with a rounded point of minimum radius of 0.15 mm. the cone angle being 50 degrees. The steel cup has a minimum radius at the bottom of the cup of 0.5 mm. and a cone angle of 70 degrees. When employing magnet steel having a coercive force of 300 Oersteds and a remanence of 4,000 Gauss, a coil of 1.0 inch diameter and 1.39 inches long with a width of 0.3 inch and working in a gap of 0.07 inches length gives a torque such that the friction of the pivots is negligible, as also is the torque due to electrostatic attraction of the pointer if the non-vitreous window 4 is rubbed. Specification 480,726, [Group XXXVI], is referred to.
