An apparatus for slip lasting and subsequently releasing a shoe upper comprises a number of independently operable slip lasting and releasing devices arranged at the upper horizontal run of a conveyer, each device having a slide carriage 70 operated by a system of levers and a cam through a driving shaft 65 rotatable synchronously with the conveyer drive and the releasing device also possessing a mechanism for disengaging a locking pawl 48 of a shoe last 30 mounted on the conveyer. The slide carriage 70 comprises walls 5, 6, a lever 11, its movement being limited by a screw 15, carrying a pad 13 and a lower support 17 of adjustable position having an abutment face 18, members 11 and 17 being connected by a compression spring 14. Carriage 70 moves on ball bearings 9 in groove 72 of guide members 71. Support 17 is connected to one arm of a three-armed lever 28 through a pivoted link 25. Another arm 28<SP>1</SP> of lever 28 co-operates, under the action of a spring 33 secured to the third arm of lever 28, with a cam 29 (lasting carriage) 47 (releasing carriage). In the releasing device the carriage 70 also possesses a cam-operated lever 38 which actuates a spring-loaded button 46 to disengage the locking pawl 48. An upper sewn to an insole is placed on a last 30, the forepart of which is tilted upwardly with respect to the heel part. The last 30 passes to the slip lasting station where pad 13 and face 18 engage the upper, the forepart of the last being moved downwardly and the last is subsequently locked. At the releasing station the last is broken by the engagement of pad 13, face 18 and button 46 so that the shoe may be removed from the last.

Abstract: 1,188,015. Coated lamp bulbs. GENERAL ELECTRIC AND ENGLISH ELECTRIC COMPANIES, Ltd. 23 Sept., 1968 [12 Oct., 1967], No. 46590/67. Heading B2K. [Also in Division H1] An electric discharge lamp comprises a fused silica envelope having transparent protective coating on the envelope interior consisting of the dioxide of Ti, Zr or Hf-envelope. The coatings may be formed by heating the envelope to 1000 to 1250‹C while exposed to vapours of titanium, zirconium or hafnium esters of the lower aliphatic alcohols which latter are thermally decomposed. Prior to the introduction of the organic compound vapor, the tube may be evacuated, or filled with air or an inert gas. If the tube is not filled with air, subsequent heating of the coated surface to 800‹C in air is necessary to remove deposited carbon.

Abstract: 1397815 Telescopic loading tube; loading tankers COMPAGNIE GENERALE D'AUTOMATISME 11 Oct 1972 [11 Oct 1971] 46921/72 Headings B8T and B8E A telescopic loading tube for fluid or pulverulent materials is suspended from an overhead carriage 3 on a transverse arm 4 and frame 5 capable of moving parallel to the direction of movement of a tank to be filled or emptied. Support cables 13, suspended from pulleys 11 are attached to opposite sides of the external portion 14 of the loading tube; which has exit holes 15 at its lower end near end plate 16. The inner portion of the telescopic tube 17, joined at its upper end to inlet pipe 18, is rigidly attached to a collar 19, which is elastically linked by springs 20 to a disc cover 21. Watertight joints 26 connect inner tube 17 with outer tube 14. A closure sleeve 27 is attached to outer tube 14, and shoulder 28 bears on the periphery of a deflector 29 on end plate 16; and an exhaust pipe 32 is attached to sleeve 27. On lowering the pipe, sleeve 27 co-operates with tank neck 31 and allows cover 21 to descend to contact sleeve 27 and prevent collar 19 with the attached inner loading tube 17 from further downward movement, but does not prevent outer portion 14 from continuing to the bottom of the tank where it is stopped, since cables 13 are free to run in openings 33, 34 in collar 19 and cover 21. To ensure that tubes 14 and 17 are held together during the initial descent, a cam 36, arranged between the end of rod 37 of a jack 38 placed between collar 19 and cover 21, is pivoted about an axls 39 so that spiral spring 41 operates and engages edge 42 of cam 36 into notch 43 on tube 14. Automatic disengagement occurs when crown 30 of sleeve 27 engages on tank neck 31 causing collar 19 to approach cover 21 and thus engaging projection 44 on cam 36 against abutment 45 to disengage edge 42 from notch 43.

Apparatus for wet-treating fabrics comprises a cylindrical vat 2. having a horizontal axis and injection nozzles 25-32 fed by a pump recirculating the bath liquid through suction nozzles, e.g. perforated pipes 17, 18, disposed inside squirrel cage rotors 10, 12 which rotate at a speed substantially equal to that of the bath liquid, over which the fabric passes in non-slipping engagement and which cause spreading out and relatively rapid movement of one section of the fabric, while the remainder moves relatively slowly and is sinusoidally folded in a deposit zone at the bottom of the vat. Circulation of the fabric is effected by movement of the path, aided by the rotors. As shown, sinusoidal folding is effected by nozzles 30 and 32, the former of which operates only intermittently. A support 6 may be provided which separates the folded and unfolded zones of the material, channels its movement in the bath and prevents, by virtue of its inclined face, the rising of the folds to the surface. The vat may be divided into compartments (Fig. 2) for treating several lengths of material, and one end of the vat may be a removable cover, to which are attached all the internal parts 6-12, on a wheeled carriage.

[Also in Division G1] A device for dispensing paper from a roll of such material comprises a roller 1 mounted for rotation inside a loose roll of paper and for rotating the roll when it is tightened on to the roller as a result of a pull on the paper, the roller tending subsequently to loosen the tightened roll and collars 10 for applying a frictional drag to the inner end of the paper therby tending to retighten the roll on the roller as a result of the pull on the paper. Sleeves 4 having toothed flanges 5 are freely mounted on a shaft 2 to which the roller is fixed. The sleeves are coupled for rotation in unison by gear wheels 6. Initially a length of paper is loosely wound on the stationary roller 1 by inserting the leading edge of the paper under clips 9 and rotating the sleeves 4. A pin 8 is then inserted in aligned holes in a frame 3 and one of the flanges 5 to prevent rotation of the sleeves and the roller is rotated until its attains a speed approximately equal to the speed at which the paper is to be dispensed. The pull on the paper is then supplied by a pair of spring loaded pinch rollers (not shown), causing the paper to be tightened on the roller and the inner end of the paper to be withdrawn from the clips. The rotating roller, however, tends to loosen the roll of paper but the collars 10 which are made of polyurethane foam cause the roll to be retightened. The device enables the paper to be unrolled at a high speed.

Abstract: 1324380 Monitoring reactors SIEMENS AG 19 Oct 1970 [24 Oct 1969] 49607/70 Heading G6C A pressurized water reactor has a pressure vessel 11 provided with a removable cover 12 and containing a core comprising fuel elements 2 arranged as shown in Fig. 1. Certain of the fuel elements 2 contain control rods 3 which penetrate the cover 12 through sleeves 21. It is required to measure the neutron flux in numerous ones of the fuel elements 2 by means of guide tubes 6 inserted in those fuel elements. The tubes 6 serve for guiding measuring probes and are diagrammatically shown in Fig. 1 as triangles. As diagrammatically shown in Fig. 1 four tubes 6 are connected by a yoke 5 to a single instrumentation tube 4 penetrating the cover 12 above a peripheral portion of the core which does not contain control rods. Thus the number of cover penetrations for the instrumentation is reduced and these penetrations do not interfere with the control rods. As shown in Fig. 2 the yoke 5 extends radially from the tube 4 and supports a number of guide tubes 6 extending through certain of the fuel elements 2 in the core, the upper ends of the guide tubes terminating in the tube 4. The tube 4 is located by a sleeve 15 upstanding from the core grid 14 and penetrates the cover 12 through a sleeve 13 in which it is sealed by means described with reference to Figs. 7, 8 (not shown). To remove the instrumentation the sealing means is released and the cover 12 and sleeve 13 are removed whereupon the tube 4, yoke 5 and guide tubes 6 may be lifted from the core. To prevent damage to the long slender guide tubes 6 on their insertion in the core s supporting tool is used as described with reference to Figs. 9, 10 (not shown).
