Title: Improvements in or relating to the packaging of liquid or solid material, and the packaging of small objects or articles
IPC: B65B9/04
Filed: 1947-09-23
Abstract: 643,742. Packing. CASCELLOID, Ltd., SENIOR, H., and BROWN, J. S. Sept. 23, 1947, No. 25833. [Class 94(i)] A method of packaging liquid or solid material or small articles comprises producing a longitudinal series of compartments C, each open at one side at least, in a strip-like body formed from two opposed laminµ of a thermoplastic material by the formation of spaced heat-seal lines transverse to the length of, and uniting together, the two laminµ, introducing the material or articles into the compartments and then closing the compartments by heat sealed joints. In Fig. 2 the edges 2 of two separate strips 1 of material are united by a longitudinal heat sealed joint 3 and then the strips are provided with spaced transverse joints 4. The compartments C thus formed are then filled, and sealed by joints 5. Alternatively the transverse joints may be formed before the first longitudinal joint. Instead of using two separate strips, a long single strip folded midway between its ends may be used, the ends of the strip being connected by a sealing joint before or after forming intermediate transverse joints or/and the first longitudinal joint (Fig. 6, not shown). In Fig. 4 a length of tubular material 6 is flattened and united transversely at intervals by a series of spaced sealing joints 7 running from edge to edge of the flattened tube. The tube is slit longitudinally between adjacent joints 7 to form mouths such as 8 at the opposite ends of the compartments C. The mouths 8 are ultimately closed by heat-sealed joints 9. In a further example (Fig. 7, not shown) compartments are formed by joining two opposed strips of material by a continuous series of right-angled or L-form joints. each constituting a closed side and bottom edge of a container. In a still further example a double width of strip material is folded longitudinally along its centre line and provided with transverse joints as before. The strip material may be drawn from a roll and folded, the leading ends sealed together, the opposing laminµ progressively joined transversely, material fed into the compartments by a hopper or chute and the longitudinal meeting edges subsequently heat sealed. Suitable thermoplastic packaging materials are polymerized vinyl chloride, or a copolymer of vinyl, or polyethyene. The sealing joints may be formed electrically by high frequency or infra-red heating, or by jets of gas flame. The containers formed by any of the above methods may be separated from the strip by severing along the transverse seal lines unless the seal is not sufficiently wide, in which case double seal lines are made. Specification 533,657 is referred to.

Abstract: 425,094. Electric signalling systems. SANDISON, A. G. S., Kelda, Baltasound, Shetland. Sept. 17, 1934, No. 26627. [Class 40 (i)] In a system for indicating, recording, or integrating electrically the values of physical quantities, errors due to voltage variations of the supply are compensated by employing watt-meter type indicating &c. instruments, one circuit of which carries current which varies directly as the supply voltage and the other circuit carries current which is automatically regulated in the inverse proportion to the supply voltage. In one arrangement, one circuit is connected across the supply and includes an impedance which is variable by the physical quantity to be measured. The other circuit includes a solenoid which has a spring-controlled core adapted automatically to regulate the current inversely according to the variations of voltage. The movements of the core are also controlled by a fluid dash-pot. In the arrangement shown in the Figure, one circuit of the watt-meter type instruments 1, 2 is supplied from secondary windings 16, 17 associated with a primary winding 21 supplied from the mains 4 through a solenoid 5 which automatically regulates the current in its circuit in the inverse proportion to the variations of voltage. The solenoid 5 has a core 6 supported on a pivoted lever 7, 10 controlled by a spring 9. The arrangement is such that the core 6 takes up positions corresponding to different voltage values, the different positions effecting corresponding alterations of impedance and current. As the core 6 moves within the solenoid the magnetic pull exerted by the solenoid becomes less due to the decrease of current, and the counter-torque exerted by the spring 9 also is arranged to become less as the arm 10 moves upwardly by the provision of an acute angle between 8, 10 and 9. The coils 16, 17 are wound in opposition and a movable core 19 is operable by the physical quantity to be measured. A short-circuited ring 20 is provided to maintain the impedance of the coil 21 constant for all positions of the core 19.
