Filed: 1963-08-30
Abstract: 988,840. Packaging-machines. FR. HESSER MASCHINENFABRIK-A.G. Aug. 30, 1963 [Oct. 23, 1962], No. 34346/63. Heading B8C. A machine for the vacuum or special atmospheric packaging of articles, in particular block-shaped foodstuffs, comprises, Figs. 1, 4, a pocketed and intermittently rotatable conveyer wheel 14, a folding tube 15, 16 with associated pusher 10, a wrapping-web feed device and evacuating chambers 71, 72 mounted on a rotatable drum 70. Articles are brought by a horizontal conveyer 1 to a transfer device 5, 6 which transfers them to the folding tube 15, 16, the associated pusher 10 inserts the articles together with a wrapper into the pockets 13 of the conveyer wheel 14, open-ended packages are formed by a folding and sealing device 35, 36, 45 and the packages are evacuated or filled with a protective gas and then sealed in the chambers 71, 72. The transfer device comprises a star wheel 5 and a movable frame 6, the star wheel picking up each article G to deliver it to the frame, during which motion the article is rotated 90 degrees about a horizontal axis, and the frame moving horizontally to bring each article in line with the pusher 10. The wrapping-web feed device comprises vertically reciprocable grippers 30, 31 (Fig. 3, not shown) which draw the web, preferably of heat sealable material, from a roll V and the web is cut by knives 11, 12. The folding and sealing device comprises heatsealing jars 35, 36 and a rod 45 having a crossstrip 37 attached thereto which moves with the pusher 10 when an article G is inserted into a pocket 13, but remains adjacent the article when the pusher is withdrawn (Fig. 5, not shown) so that positive folding of the wrapper is effected before sealing takes place. The seam so formed is folded flat by a fixed plate 50 when the conveyer wheel 14 is rotated and the partially-wrapped article is brought to an end folding and sealing device comprising folders 52, 53 and heat sealing jaws 56, Fig. 7. The folders 52, mounted on leaf springs 54, are inserted into the open ends of the wrapper and horizontal movement of the folders 53 towards one another causes folders 52 also to approach one another. End seams as shown in Fig. 9 are formed, sealed as at S by jaws 56 to leave a central evacuation passage. After further rotation of wheel 14 packages delivered therefrom are moved on to a lifting plate 61, Fig. 1, by a pusher 60 and from the plate are dispatched in pairs on to a holder 69 associated with each evacuating chamber 71, 72. During rotation of the drum 70 the chambers are sealed and evacuated and the packages are themselves sealed by high-frequency heat sealing jaws 81, 82 (Figs. 10, 11, not shown) when emptied of air or charged with a suitable protective gas.

Title: An explosive projectile including an electric firing device
IPC: F42C11/04
Filed: 1969-07-08
Abstract: 1,261,097. Explosive projectiles with electric fuzes. BREVETS ELECTRO-MECANIQUES S.A. 8 July, 1969 [25 July, 1968], No. 34358/69. Heading F3A. [Also in Division H2] An explosive projectile comprises an electric fuze 28 ignitable from a source of energy upon impact of the projectile, a support 2 for moving the fuze adjacent the explosive charge of the projectile, a conductive part 38 constituting a shunt of the current leads 27 and 33 of the fuze, and abutment means 34 for displacing the conductive part 38 against the action of a spring 39 so as to interrupt the effect of the shunt when the fuze is adjacent the explosive charge of the projectile. The energy source is constituted by a charged condenser 24 which is charged through a diode 23 by an electromagnetic generator. The generator comprises an armature 10, 11 with winding 12 and a core 14 constituted by a permanent magnet. A stud 19 short-circuits the condenser. Upon firing the projectile, the core 14 sets back, rupturing a disc 18 and withdrawing the stud 19, so that the condenser is charged by the generated current. The support 2 also sets back, rupturing a disc 3 and is subsequently moved forward by springs 8 and 9. Engagement of a stud 41 in a zig-zag groove 40 delays this movement. When the abutment means 34 first reaches an electrical contact 43, 44, inadvertent closure of the firing circuit prior to impact merely results in the harmless discharge of the condenser through the conductive part 38 and the abutment means. However, in normal circumstances, when the fuze reaches its final position, the abutment means 34 lifts the conductive part away from the current leads and thereby permits firing of the fuze upon impact.

Abstract: 1,115,115. Water heaters. G. BAUKNECHT ELEKTROTECHNISCHE FABRIKEN G.m.b.H. 1 Aug., 1966 [13 Aug., 1965], No. 34407/66. Heading F4A. An electrically heated tank 11 for producing boiling water, has a sleeve 6 supported in an oval aperture 5 in its top. The sleeve 6, which is formed with a flange 7 resting on the cover 12a of the casing 12 surrounding the tank, and which is secured to the cover of the tank by a soft sealing ring, is provided with a horizontal wall 4 defining a plurality of steam passages 2 to permit venting of the inside of the tank to the atmosphere. Screwed to but spaced from the wall 4 is a metal condensing cap 1 having an annular rim 9 which co-operates with a rim 10 of the wall 4 to define a narrow peripheral outlet, so that the majority of the steam produced condenses on the underside of the cap 1 and returns to the tank 11 rather than escaping to atmosphere. Communicating with the lower end of tank 11 through the front wall 11a and an angle connection 19 in which it is sealed by soft seal 20, is a water level indicator tube 14 containing a coloured ball 15. At its top end the tube 14 is closed by a plastics or rubber cap 17 which is attached to the tank 11 by clamp 18a, 18b and which has a central aperture 16 communicating with the atmosphere within casing 12. In the event of outlet pipe 25 becoming blocked, water is prevented from flowing out of tube 14 over the electrical switch-gear within casing 12 by the ball 15 which seats against the edges of aperture 16 so sealing off the tube 14.

Title: Colouring cellulosic textiles
Inventor: ALSBERG FREDERICK RICHARD
IPC: D06P/
Filed: 1954-11-29
Abstract: Cellulosic textile materials are coloured by impregnating them, locally or otherwise, with an aqueous medium containing an anthraquinonoid or other polynuclear quinone dyestuff having at least one ionogenic solubilizing group, such as a sulphonic acid or carboxylic acid group, and also at least one amino or substituted amino group carrying as N-substituent a 1:3:5-triazine radical containing at least one halogen atom attached to a carbon atom of the triazine ring, and then subjecting the materials to the action of an acid-binding agent in aqueous medium.  Alternatively, the textile may be treated, before, during or after the application of the dyestuff, with an aqueous solution of a substance which on heating or steaming liberates an acid-binding agent, in which case heating or steaming is finally applied.  As applied to printing, the acid-binding agent or a substance which, on heating or steaming, liberates an acid-binding agent, may be incorporated with the dyestuff in the printing paste, and the printed material may then be heated or steamed.  Suitable acid-binding agents are caustic soda, caustic potash, sodium carbonate or bicarbonate, trisodium phosphate and sodium metasilicate, suitable substances liberating the acid-binding agent on steaming being sodium bicarbonate and sodium trichloroacetate. Electrolytes, such as sodium sulphate or chloride, may be added to the aqueous solution of the acid-binding agent.  The dyebath or printing paste may contain the usual additives such as urea, sodium sulphate, sodium alginate, cellulose ethers, starch and locust bean gum.  The material may be padded with the dyestuff solution and dried prior to treatment with the acid-binding agent.  In continuous processes, e.g. employing the "molten metal" technique, the drying step may be effected at 70-170 DEG  C.  The dyed materials may finally be treated with aqueous acetic acid, rinsed, dried, soaped, rinsed and dried. Examples of dyeing and printing are given. Suitable dyestuffs are those prepared by adding an aqueous solution of disodium - 1 - amino - 4 - (41 - amino) - anilinoanthraquinone - 2:31 - disulphonate or trisodium - 1 - amino - 4 - (41 - amino - anilino)-anthraquinone - 2:31:5 - trisulphonate or trisodium - 1 - amino - 4 - [41 - (411 - amino)benzeneazo]anilino - anthraquinonetrisulphonate to a suspension of cyanuric chloride in cooled aqueous acetone, neutralizing with sodium carbonate and finally adding salt to separate the dyestuff.  Specifications 342,167, 363,897, [both in Group IV], 772,030 and 781,930 are referred to.
