Abstract: 1,212,877. Seaming non-metallic sheet material. CONTINENTAL CAN CO. Inc. 28 Dec., 1967 [28 Dec., 1966], No. 58777/67. Heading B5K. [Also in Divisions B8 and H5] One side of an electrically non-conducting material 14 is heat sealed to another surface by a heat sealable material by applying at least one resistive heating element 10 to the one side of the material 14 and applying a high frequency alternating voltage to the other side of the material 14 to produce a flow of alternating current in the element 10 by capacitive coupling to heat the one side by Joulean heating. As shown in Fig. 1, the element 10 is fixed to a substrate layer 12 secured to the non- conductive layer 14 and is heated by placing the layer 14 adjacent to electrodes 16, 18 positioned to apply the tangential portion of an electric field generated therebetween to the element 10. The method is applicable to sealing frozen food cartons which are imprinted, in the regions to be sealed, with heating elements comprising electro-conductive ink, the conductive material being carbon, aluminium, silver, platinum, gold, nickel, tin or copper. The heating elements are arranged in any of the patterns shown in Fig. 2 and are covered with polyethylene or a heat sealable wax, e.g. an ethylene vinyl acetateparaffin blend. A carton 34, Fig. 7, provided with conductive lines 10<SP>1</SP> is moved past a pair of etched comb-like electrodes 22<SP>1</SP>, 241 whose individual teeth are intermeshed and which are embedded in a polystyrene block 26 and coated with a polystyrene sheet 28. In Fig. 9, filled cartons 34 are fed by a conveyer 40 past electrode structures 36, 38..to seal the side flaps and then past chill rails 42, 44 to cool the seals. The front flap of the carton is sealed by subsequently moving it past a similar electrode structure and chill rail. The flaps of milk cartons (45), Fig. 10 (not shown) having conductive lines (46) thereon, are closed by cams 50, are sealed by passage between electrode structures (52), (54) and are cooled by chill rails (56), (58).

Title: Producing form parts by pressing
IPC: B27N5/02
Filed: 1968-07-30
Abstract: Hollow object is produced by pressing a mixture of organic fibrous materials not arising of their own accord and a binder hardened under the influence of heat. Surplus material occuring at the edges between two outer limiting surfaces of the hollow body upon its being filled with the mixutre is pressed to a bar-shaped object running along the edges. The bar-shaped object can be connected to the even-width edge of the hollow object by an extremely thin connecting piece to form a sort of comb running along this edge, the comb being of the same thickness as the hollow object formed, and after the latter has been removed from the form, the thin connecting piece can be broken open.

Title: Injection moulding machine core locking - device
IPC: B22D17/24
Filed: 1969-04-04
Abstract: Core operating mechanism for injection moulding machine with stationary plate and slide plate has a rigid frame, forming a seat. This is mounted on the slide plate between the stationary plate and the slide plate. A core bearing slide moves to and fro from the first position on the frame, in which position the cores mounted on the slide are withdrawn from the mould, and a second position in which the cores are slid into the corresponding mould cavity. Means are supported by the frame to move the slide between first and second position. Latching devices are positioned on the slide which have a latching arm that pivots on the slide and which has an outer end complementary to the frame accommodating seat. Means are provided to move the outer end of the latching arm in contact with this seat to latch the slide against movement in relation to the frame and the cores in relation to the mould cavity, independent of the force exerted for moving the slide to and fro. The latter can be operated to move the latching media from the engaged position, so as to allow for movement of the slide in relation to the frame and for withdrawing the slide in relation to the frame and the withdrawal of the cores from the mould cavity.

Patent NL-7806197-A (NL)
Title: Transfer of oil from offshore wells to coast - uses mooring riser with buffer vessel and shuttle tanker so that oil can flow continuously without transfer pipeline (NO-8.10.79)
IPC: B63B22/02
Filed: 1978-06-07
Abstract: Oil is transported is stages from an underwater offshore oil well to the coast. The oil is initially delivered to a floating buffer vessel from which it is transferred via a flexible pipeline to a tanker which travels to and from between the buffer vessel and the coast. The buffer vessel is pref. equipped with a fixed distribution head by means of which the oil collected in the vessel is discharged into the flexible hose. To enable the hose to be extended and retracted. It runs around a guide disc mounted on rails so that the movement of the disc along the axis of the ship enables the discharge end of the hose to be drawn out to the transport vessel. The buffer vessel is pref. moored to a column with its foot on the seabed, a swivelling fluid coupling on the surface and a distance buoy enable the vessel to be moored and connected to the fluid coupling via another flexible pipe. The arrangement is such that the buffer vessel is able to adopt the position which offers the least resistance to driving seas or sind and, if necessary, use may be made of dynamic positioning on the vessel itself to limit the force exerted on the mooring device. The collection and transfer system offers a cheaper alternative to the construction of an underwater pipeline.
