[Also in Division B8] Containers e.g. bottles, sachets which are at least partially filled are formed from thermoplastics by blow-moulding a plurality of openended containers joined end-to-end, filling the containers while still joined and then sealing them at their ends. As shown in Fig. 1, material is extruded from an extruder 1 through die head 2 and sizing die 3 in which is a mandrel 4 for supply of blowing fluid, the mandrel being bored to take a tube 5 for supply of filling medium. The extrudate is passed into moulds 7, the parts of which may be pivoted (Fig. 2, not shown) or linearly reciprocable (Fig. 7, not shown) for opening and closing. The blown articles are then sealed by sealing jaws 9 and may be separated simultaneously thereby or subsequently. The articles may be squeezed during sealing by fingers 20 so that the bottom seal will invert on release of pressure. The moulding material, blowing fluid and/or filling medium may all be sterile. The sealing jaws (Figs. 5, 8, not shown) each comprise two spacing portions (24) pivoted at (46), each carrying a cutting portion (23) having a heating element (45) at its end, and carried by a belt driven by mechanism (25-28) in synchronism with the belt carrying the moulds 7.

Abstract: 990,363. Coating apparatus. EASTMAN KODAK CO. Dec. 11, 1961 [Dec. 12, 1960], No. 44166/61. Heading D1L. [Also in Divisions B2 and B6] A process for hot melt coating comprises coating a hot melt coating on to a substrate to be coated, and contacting the coating against a chilled roll whose surface has been uniformly coated with steam sufficient to deposit a thin aqueous film thereon. As shown paper substrate passes round an idler roller 13 to coating roll 1 which applies hot melt coating 8. Roll 1 has a doctoring blade 11 and a rod 10 is provided to smooth the coating. The coated paper passes an idler roller 12 and around chilled roller 2 which has steam projected on to the surface thereof from a perforated steam pipe 6. In another embodiment sheets of paper are fed between a coating roll and an impression roll where the hot melt, applied by a heated spatula knife to the coating roll, is transferred to the paper. The coated paper then passes between the impressing roll and a refrigerated embossing roll to the surface of which steam is applied from a perforated pipe as in previous embodiment. The steam produces a thin water film on the chilled roller and thus prevents sticking of the coating to the roll. Specification 990,634 is referred to.

Abstract: 1353594 Feeding sheets J & P COATS Ltd 15 Sept 1971 [13 Nov 1970 22 April 1971] 45207/70 and 10772/71 Heading B8R Pieces of sheet material placed in turn on a table 40, Figs. 1 and 2, are fed by a plurality of spaced apart clamps 11 slidable along an endless guide bar 2 to the nip between a transfer belt 5 and a lower belt 6, Fig. 4, which carry them through a sewing-machine 4. The clamps release the sheets as they are engaged by the belts, and are then returned by a friction belt 12 along the return flight 2A of the bar 2. The belt 6 is formed of magnetically influenced material and passes beneath magnets 8 between the poles of which the belt 5 passes, so as to grip the sheets. The returning clamps pass round the bar on to the feed flight and are then stopped by a detent 22 so as to form a queue, Fig. 6. At this time, a bar 14, Figs. 1, 2, 5 and 6, carrying a plurality of slidable detent devices 15 is moved to the right by a thruster 13, the devices 15 being arrested by a stop 20 with each device 15 engaging a clamp in the queue. The bar 14 carries a series of stops 18 progressively increasing in size to the right, while the devices 15 each have a stop-receiving recess 19, the recesses being progressively wider to the right, so that each stop corresponds to and actuates one particular device 15. As the bar 14 moves to the left, the devices 15 and the clamps are thus advanced at spaced intervals to the loading position, pushing the previous series of loaded clamps towards the belt 5, with some buckling of the sheet, which is corrected by the action of a tensioning brush 15 or tensioning belt when the belts 15, 16 start pulling on the sheet. When a batch of clamps is to be advanced to the loading position, the detent 22 is released and a finger 23 engages the back of the batch. Each clamp comprises a plate 27, Figs. 7 and 9, and a slide 24 carrying a needle 25. When a pedal 38 is operated, the slides of the clamps at the loading position are raised by a bar 37 to cause the needles to penetrate the sheet, the slides being locked by pawls 30, which are released by an abutment 36 at the clamp-opening position. The pedal also operates the thruster. In order to feed successive sheets in adjoining relationship, the rear clamp of a batch is coupled to the front clamp of the following batch by means of a hook 32 on one clamp engaging a pin 34 on the other, the coupling being released by an abutment 35.

The punch 20 forms latch seats (34), (36) at either end of the recess, Fig. 4 (not shown), and the punch leading end 24 contours the bottom 38 of the recess. An alternative form of punch (42), Fig. 3a (not shown), is provided with a leading end portion (50) which pierces the bottom of the recess and enters a clearance (44) in a die (40), thereby punching a slot (52) in the needle. The slot may be punched in a separate operation after forming the recess. The latch members 54 are stamped from a strip 55 and may be formed with trunnions 62, 64 which are subsequently hardened. The latch is placed in the recess and walls 30, 32 of the recess are pressed against the trunnions, which form bearing seats for pivoting movement. Alternatively the latch may be secured by upsetting the recess wall into a hole in the latch or by a rivet.

The radiation from the source 16 is modulated by a tuning fork 20 driven by electronic circuitry and the detectors outputs are each fed to a separate identical processing channel comprising a preamplifier, narrow band pass filter, peak-to-peak detector and a log amplifier, Fig. 2 (not shown). Then the signals from the two channels are fed to a strip chart recorder and a difference amplifier which also feeds the strip chart recorder as well as a remote alarm circuit.
