Abstract: 262,024. Huntley, B. L. Aug. 21, 1926. Filling tubes and like receptacles. - A device for use in filling an ice-cream carton A comprises a shell 5 with a co-operating cap 9. The cap 9 is provided with a handle 10 which is loosely embraced by a U-shaped lever 17 which is freely slidable thereon, and is pivoted at 18 to the shell 5. The extremities of the arms of the member 17 are shaped to co-operate with lugs 22 on the shell 5. Lugs 20 on either side of the cap engage in slots 19 in the member 17 to guide the cap. A spring-pressed latch lever 23 engages the member 17 to lock the cap in position on the shell. At the lower edge of the shell an annular cutting blade 6 is provided having an internal shoulder 7 which supports the carton A. The internal edge of the blade is cylindrical and the external edge bevelled. A cutting wire 8 extends diametrically across the shell so that when the container has been pressed into the ice-cream and filled, subsequent rotation cuts this cream from the body remaining in the can. The cap 9 is now released by pressing the lever 23 and turned to a position as shown in Fig. 3 so that the filled carton can be removed and replaced by an empty one. The cap 9 is provided with sight holes covered by a transparent plate, and with air escape passages 12. In order to prevent suction between the carton and the shell 5, longitudinal and circumferential air passages with spaced vent-ports are provided.

Apparatus for determining traffic congestion (or concentration), i.e. the number of vehicles in a unit length of road, comprises a detector 10 which closes a contact 12 each time it is depressed by passing vehicles to provide current pulses of duration dependent on the time of passage of the respective vehicles, the pulses being fed to a leaky integrator 14, the output of which is a measure of the rate of occurrence of the pulses multiplied by their respective durations and hence is a measure of the congestion which may be indicated at 16. The integrator consists of a high gain amplifier 30 with input resistor 32, feedback capacitor 31 and a high resistor 33 to effect the " leakage." The number of vehicles passing over the detector 10 is measured by a further leaky integrator 19 to which the pulse output from the detector 10 is fed via a normalizer 18 which converts the pulses into constant duration pulses. This count may be indicated at 20. The ratio of the output of the two integrators 14, 19, i.e. the vehicle speed, may be determined at 21 and indicated at 22. Specifications 1,004,413 and 1,004,415 are referred to. Reference has been directed by the Comptroller to Specification 958,793.

Title: Process and apparatus for Manufacturing Foamed Articles of Thermoplastic Materials
IPC: B29C48/515
Filed: 1968-05-03
Abstract: 1,152,306. Twin screw extruder for foamed thermoplastics. LAVORAZIONE MATERIE PLASTICHE L.M.P. S.p.A. 3 May, 1968 [10 May, 1967], No. 21131/68. Heading B5A. Foamed thermoplastics articles are made by a twin screw extruder in which the screws rotate in the same direction, and which comprises a heating and mixing portion which is also designed to produce two spaced sealing plugs of the thermoplastic material at its upstream end, a metered supply for a fluid blowing agent in an intermediate portion and a homogenizing and cooling portion between the intermediate portion of the extruder and the die. Granular thermoplastics material is fed into the upstream end of the apparatus, melted and mixed in the first section, mixed with the blowing agent, cooled in the homogenizing section and extruded through the die; escape of blowing agent being presented by the plugs of thermoplastic material and by the viscosity of the material and the close meshing of the extruder screws in the outlet section. As shown the extruder comprises a barrel 10, two intermeshing screws 11, 12, an inlet 14 for granular thermoplastic resin, an inlet 22 for a metered flow of fluid blowing agent and a die 18. Heating coils 30A, 30B, 30C, 30D and cooling chambers 32, 32<SP>1</SP>, 32<SP>11</SP> are arranged along the outside of the barrel and cooling fluid is fed through tube 41 to the end of the hollow extruder screws, returns through section F in the space between the screw 11, 12 and tube 41 and passes through the rest of the screw between tube 41 and a tube 43 thermally insulated from the screw. Precompression and heating of the granular thermoplastic material starts in section A comprising coarse pitch screws 11A, 12A and heater 30A. The pressure on the material builds up between sections A and B as the pitch of the screws 11B, 12B in section B have a smaller pitch than screws 11A, 12A and the material is further heated and passed into free room 35. The screws 11C, 12C of section C have a reverse pitch of absolute value about the same as that of section B and gaps 36 are formed in the screw threads in a stepped relationship defining a helical path through the screw. These reverse threads cause a plug of thermoplastic material to form in space 35 and a similar plug in space 38 between sections D and E which are similar to B and C. Section E is not heated or may be cooled to assist absorption of the blowing agent at 20. The meshing screws 11F, 12F in section F mix the softened polymer and blowing agent thoroughly and also cool the polymer so that its viscosity on emerging from the nozzle 18 is sufficient to prevent collapse of the cells formed by the expanded blowing agent. The process and apparatus can be used to manufacture plates, slabs, bars and tubes from foamed thermoplastic resins, e.g. polyvinylchloride, polyvinyl acetate, polystyrene, polyamides and polyethylene.
