Title: Improvements relating to the sterilization of parts of metal containers used in canning foodstuffs
Inventor: HAWLEY HENRY BERNARD
IPC: B65B55/06
Filed: 1951-01-18
Abstract: 700,188. Sterilizing. APLIN & BARRETT. Jan. 16, 1952 [Jan 18, 1951], No. 1415/51. Class 81(1) Caps for containers of foodstuffs and beverages are sterilized before their application to the containers by being passed close to a high frequency induction heating coil situated near the point at which the containers are capped. A capping machine of known type may be employed and preferably the parts of the machine adjacent the heating coil are made from, or are plated with, a metal of high heat conductivity or from a material which is a non-conductor of electricity. As shown in Fig. 2 the caps 8 are fed along a track 9 by a feeder blade (not shown) and are then carried round a curved part 10 of the track by a rotating arm (not shown) under an induction heating coil 11 and thence to a position 12 where they meet the containers 13, fed from a filling machine (not shown). After capping the containers and caps are secured together by seaming.

Title: Shield for a prestressed nuclear reactor pressure vessel
IPC: G21C13/093
Filed: 1974-01-11
Abstract: 1443302 Pressure vessel SIEMPELKAMP GIESSEREI KG 11 Jan 1974 [13 Feb 1973] 01532/73 Heading B1X [Also in Divisions F2 and G6] A shield for a pressure vessel, particularly suited for a nuclear reactor, includes a removable cover 3 secured to the body 2 by means of anchoring devices which anchor the ends of prestressing elements 8 such that the cover can be removed without releasing the tension exerted on the body. The body 2 is composed of cast-iron segments 5 clamped together by the elements 8 which pass through ducts 7. Each similar duct 7 in the cover 3 is lined with a sleeve 12, comprising two halves 12a, 12b, affording a collar 11 projecting above the upper surface of cover 3. Each bundle 9 of elements 8 is secured to an anchor plate 10A which is of smaller external diameter than the internal diameter of duct 7. Anchor plate 10A has an external screw thread 16 on to which is screwed a nut 14. A spacer 15 in the form of two part-annular segments 15a, 15b is positioned between the nut 14 and cover 3 whereby the tension in elements 8 is transferred as a clamping force to both cover 3 and the rim 6 of the body, on which the cover rests. The lower end of each sleeve 12 also rests on rim 6.  To remove cover 3, the anchor plate 10A and nut 14 are initially raised by an hydraulic press so as to release the spacer 15 the segments 15a, 156 of which are then removed laterally (Fig. 4, not shown). The plate 10A and nut 14 are then released and abut the end of collar 11 so transferring the tension of. elements 8 to the body 2 via sleeves 12 and rim 6 while leaving cover 3 free. Nut 14 is then unscrewed from plate 10A (Fig. 5, not shown) whereupon the cover 3 is removed vertically (Fig. 6, not shown). A similar securing arrangement can fasten the base 4 of the vessel.

Title: Process for the dehydrohalogenation of halohydrins
IPC: B01J41/04
Filed: 1958-01-17
Abstract: Chlorohydrins are dehydrochlorinated to give the corresponding epoxy compounds by contacting an aqueous solution of a chlorohydrin with a strongly basic anion-exchange resin, an aqueous solution of the dehydrochlorinated compound being obtained and the resin being regenerated by washing with an aqueous solution of an alkaline agent followed by rinsing with water.  The preferred anionexchange resins are polystyrene-based resins having active quaternary ammonium groups.  The regeneration is advantageously effected by the circulation of an aqueous solution of caustic soda in contact with the chlorinated resin.  Examples are given of the conversion of glycerol monochlorhydrin to glycidol, diglycerol chlorohydrins to the corresponding epoxy compounds and styrene chlorohydrin to 1,2-epoxy ethylbenzene. These products may be hydrated to give glycerol, diglycerin and phenylglycol respectively.

Title: Method of Forming a Moisture Impervious Panel
IPC: D21J1/08
Filed: 1967-01-12
Abstract: 1,181,711. Coated sheet material. AMERICAN COLLOID CO. 12 Jan., 1967 [1 Feb., 1966], No. 1801/67. Heading B2E. [Also in Division B5] A rigid, moisture impervious panel is produced by applying a layer of binder and granular bentonite in the unswollen state to at least one surface of a supporting sheet in proportions such that the bentonite forms the major proportion of the layer and curing the binder so as to form a coherent moisture impervious layer containing the bentonite. A mixture of bentonite and fluid organic binder which is meltable before curing may be applied to the corrugated side of a single-faced corrugated paper. A second layer of facing paper may be applied to the corrugated board. In Figure 1 a single-faced corrugated paper board 11 passes under a hopper 12 containing a mixture of bentonite and organic binder in fluid form. The paper board 11 includes a face sheet 11 carrying fluted or corrugated sheet 11b. A radiant heater 15 bonds the bentonite granules to the corrugated board. A second facing sheet 16 may be passed over the surface of the corrugated paper 11 to provide a double-faced corrugated sheet. A second radiant heater 18 completes curing of the bentonitic mixture. The board is then bassed between a pair of pressure rollers 19, 20 and then through a shear device 21. The support may be Kraft paper coated on both sides with glue, which is then passed through a fluidised bed of bentonite. In another embodiment coarsely crushed granular bentonite in suitable organic binder may be spread over the bottom surface of a paper container comprising a bottom surface and long side flaps. The side flaps are then folded inwardly (Fig. 7 not shown) and the assembly passed between a pair of pressure rollers.

Abstract: 782,015. Automatic tension control systems. BRITISH CELANESE, Ltd. Jan. 20, 1955 [Jan. 22, 1954], No. 1966/54. Class 38 (4). [Also in Group XXXVIII] A tensiometer for controlling tension in a running yarn comprises a member movable about a mean position and subjected to the tension, an electromagnet for opposing the action of the tension on the member and means for supplying energizing current to the electromagnet and for effecting a continual increase or decrease in said current so long as the member is on one side or other respectively of the mean position. Tension in a yarn 3 being stretched in a steam chamber by rollers 7, 4 running at different speeds acts through pulley 19 on the adjustably counterbalanced member 21 which bears armature 26 acted on by electromagnet 41, the current through which is controlled to keep the member substantially balanced. The balancing arrangement comprises a pair of contacts 29, 30 closed spaced on opposite sides of the member and connected to positive and negative potentials, whereby when the lower one is contacted capacitor 37 is charged, thereby raising the anode current of valve 39 which flows through the electromagnet winding until it lifts the member off the stop while if it touches the upper contact the reverse happens. Consequently, a current is maintained in the winding which maintains the member in a null position. In practice, even with a steady tension the member oscillates between the contacts, the current changing between narrow limits as it does so but the mean current is a measure of tension. The position of and distance between contacts 29, 30 can be adjusted. The voltage across winding 41 is compared with that across resistor 45 fed by valve 48 which has a bias which may be varied to determine the standard tension value. The resultant voltage is amplified at 53 and fed to windings 54, 55 of a split field motor which runs at a speed proportional to field current to alter the value of pressure which the automatic pneumatic controller 10 is set to maintain in the steam chamber, whereby to restore the tension to the standard values. Should the yarn break the member stays in contact with 29, thus cutting off the current to relay 61, thereby isolating the motor armature to stop further adjustment of steam pressure and light warning lamp 64. Specification 540,108, [Group IV], is referred to.
