Title: Improvements in parts for jet propulsion engines and their manufacture
IPC: F01D5/28
Filed: 1948-11-26
Abstract: A jet-propulsion engine part comprises a sintered ferrous body infiltrated with copper or copper alloy with a continuous coating of zinc, tin, zinc alloy or tin alloy.  In making a compressor blade, ferrous metal particles of 80 to 325 mesh are briquetted at 6-50 tons/sq. inch to form a blank with 10-30 per cent porosity by weight. The metal may be pure iron or contain up to 1 per cent carbon or a proportion of steel or alloy steel.  If the porosity exceeds 15 per cent it may be presintered, e.g. if iron at 900 DEG -1100 DEG C. for 30 minutes before compression to reduce the porosity.  The briquette is then impregnated with copper by heating it in contact with a weighed amount of copper in a clean dry protective atmosphere at 1125 DEG -1250 DEG C. for 10-15 minutes.  The copper is preferably alloyed with 5 per cent manganese and 1 per cent silicon or 2-8 per cent manganese and 1-2 per cent iron.  0.2 to 5 per nickel, titanium, phosphorus, chromium and/or sulphur may be added instead of, or in addition to, manganese, silicon and iron.  The impregnated blank may be heat-treated to alloy the metals superficially.  It is then dipped in a bath of tin or zinc at about 800 DEG C. causing the coating to alloy with the matrix metal to a depth of 0.003-0.004 inch.  To the zinc bath may be added from 1 to 30 per cent by weight of copper. Aluminium and/or tin may also be added in addition to, or instead of, the copper.  To the tin bath, up to 10 per cent copper may be added. The bath is covered with cryolite or alternatively protected by dry hydrogen or carbon dioxide, or a flux of zinc, potassium, or sodium chloride.  The coated blade then undergoes heat treatment at 350 DEG -380 DEG C. for a zinc coating or 200 DEG C. for a tin coating.  Heat treatment may be carried out in air to form a dense oxide cover on the coating.  Instead of dipping, the blade may be packed in powdered zinc or zinc alloy and heated for 3-4 hours at 350 DEG -485 DEG C. or in powdered tin or tin alloy at 200 DEG -280 DEG C.  A further diffusion treatment may follow.  Again, the coating may be applied by electroplating followed by diffusion treatment at 350 DEG -485 DEG C. for a zinc alloy coating.  Specification 644,907 is referred to.  The Specification as open to inspection under Sect. 91 states that aluminium may be added to the tin bath, and that the coating may be applied by anodizing.  This subject-matter does not appear in the Specification as accepted.

Filed: 1938-10-25
Abstract: 520,553. Milling-machines ; counterbalancing. PFAUTER, C. Oct. 25, 1938, No. 30860. Convention date, Oct. 28, 1937. [Class 83 (iii)] [Also in Group XXX] A gear-cutting or other milling-machine has the cutter 5 mounted in a vertical slide 6 which is wholly or partly counterbalanced by a weight 14'whose effect may be augmented by hydraulic pressure means. In bobbing a gear 4 the cutter 5 rotating in the direction of arrow a is fed in the direction b and tends to overrun the feed imparted by screw and nut mechanism 9 or by rack and pinion. In order to eliminate the effects of backlash in the feed gearing the counterweight 14 is hollow and moves over a fixed piston 15 and fluid supplied by a pump 17 passes beneath the piston to increase the effect of the weight and maintain the upper flanks of the nut thread constantly engaged with the lower flanks of the screw. During the feed, a slide 23 is maintained in the position shown by a solenoid 25 but for the quick return movement the solenoid circuit is broken and the slide 23 is moved so that the pump delivery can pass into the container 21. The hydraulic pressure is not used when the cutter moves in the opposite direction to the feed. The pump 17 may act as a lubrication pump for the machine.

Title: Improvements in or relating to cathode-ray tubes
IPC: H01J29/78
Filed: 1947-11-24
Abstract: 683,461. Automatic exchange systems. NAAMLOOZE VENNOOTSCHAP PHILIPS GLOEILAMPENFABRIEKEN. Nov. 24, 1947 [Nov. 27, 1946], No. 31048/47. Class 40 (iv). [Also in Group XL (a)] Cathode-ray tube apparatus for use in automatic telephony is of the kind in which an electron beam is moved continuously by deflecting means so that its point of impact on a target traces out a two-dimensional closed path and has the target formed as a collecting electrode which is continuous throughout the path or is divided into segments separatedby intervals which are narrower than the electron beam and coupled to the deflecting means through three or more avenues in such a way that when-the beam impinges on the collecting electrode the deflecting means are automatically caused to deflect the beam so that its point of impact on the collecting eleetrode moves continuously along the closed path. In the construction shown in Fig. 3 the collecting electrode is composed of separate segments 22 arranged in an annulus, the spacing between adjacent segments being narrower than the cathode-ray beam. Each segment 22 is connected to the junction point of two resistances 23, the resistances 23 being equal in number to the segments 22. and being connected in a ring, three or more points 26, 26a of which are connected to a source of positive potential through resistances 24 and to the deflecting plates 25, 25a, each deflecting plate being displaced more than 90 degrees from the corresponding point 26, 26a. The collecting electrode can be provided with further segments 29, 30 connected to the segment 22b and positioned partly behind the segments 22 and formed with recesses 29a at each interval between the segments 22 so that part of the beam can pass -through the gap between the segments. The segments 29, 30 tend to urge the beam inwardly and outwardly respectively. The segments 22 need not be spaced as shown but may be positioned one behind the other. The beam may follow any closed curved path. In the construction shown in Fig. 4 the beam is caused to follow one closed path 32, 33, 34, 35, &c. or another closed path 32, 33, 36, 37, &c. according to the strength of the beam current through the segment 33. Arrest of the beam can be effected in the arrangement shown in Fig. 3 by disconnecting a predetermined segment 22 from the ring of resistances 23 and connecting it to the diametrically opposite point in the ring. The direction of travel of the beam can be reversed if the segments of the collecting electrode have secondary emission properties and a grid carrying a suitable voltage for suppressing secondary emission is mounted in front of one' of them. Such an arrangement can be used in a a call.-finder for automatic telephone systems. In the construction shown in Fig. 7, the direction of travel of the beam is reversed at 46 with a suitable current strength and the beam comes to rest on the edges of the electrodes 50 and 46.

Abstract: 1389134 Nuclear reactor core supports CLARKE CHAPMAN Ltd 17 April 1973 [4 July 1972] 31151/72 Heading G6C A nuclear reactor core support comprises leaning post assemblies 22 (Fig. 2), and a grid assembly (for supporting nuclear fuel element assemblies), supported by the shell 10 of a diagrid vessel, passages being provided in the leaning post assemblies by which coolant (e.g. liquid sodium), above the vessel can act on the fuel element assemblies in a sense opposite to that of coolant supplied from a pump whereby faces due to hydraulic pressure the fuel assemblies are counterbalanced. The shell 10 contains radial ribs 16 and chordal ribs (18) (Fig. 1, not shown), and is closed by a top plate 20. Each leaning post assembly comprises an outer cylinder 24 extending between a rib and the top plate; the lower end of each cylinder supports radial arms 26 each carrying a fuel element support cup 28. In an embodiment of leaning post assembly 22 (Fig. 4), the arms 26 extend from a lower endpiece 30 of the outer cylinder 24 and the latter contains an inner cylinder 36 whose lower endpiece 38 is spaced from member 30. An upper end-piece 44 of the inner cylinder is integral with the upper section (not shown), of the leaning post assembly. In operation, coolant is pumped into the shell 10 via inlets 12 to fill the diagrid vessel up to the top plate 20. The high pressure coolant passes through lateral slots 60 in the lower section of the leaning post assembly and then through bores 56 to the upper section of the leaning post assembly. High pressure coolant also enters each fuel element via slots in the lower end of the support cup 28 and, after passage through the element, forms part of the body of low pressure coolant above the top plate 20. By way of bores 54 and clearances 52, 49, 50 in the leaning post assembly, the low pressure coolant reaches the space between the lower end-pieces 38, 30 and thence, via bores 59 and passages in the arms 26, passes to the interior of the fuel element support cup 28 and is applied to the fuel element supported therein in a manner to counteract the upwardly-acting force arising from the pressure drop as the high pressure coolant passes through the fuel element. In a modification of the leaning post assembly required when a downwardly-acting control rod is to enter the space within inner cylinder 36, longitudinal grooves are milled externally in the surface of the inner cylinder 36 to replace the clearances aforementioned, the inner shaft 46 is dispensed with and the inner cylinder secured in an alternative manner.
