Filed: 1968-09-12
Abstract: 1287404 Tubular films W & H M GOULD. ING Ltd 11 Sept 1969 [12 Sept 1968] 43324/68 Heading B5B Tubular film is made by extrusion of a melt through an annular orifice 3 defined by a mandrel 1 and a surrounding die 2, the mandrel being fitted with both cooling means 11 and heating means 9, the extruded tube being cooled by an external air blast from ring 10. The mandrel and die are first heated to the extrusion temperature, the mandrel by means of the induction heater 9 housed in a recess in the mandrel adjacent to the extrusion orifice; during extrusion the mandrel is cooled by circulation of fluid, preferably distilled water in stainless steel tubes housed in the cooling block 11, to a temperature in the neighbourhood of that of the die, but above the lower critical temperature of the plastics material at which a sharp increase in viscosity occurs. During extrusion air is blown through the axial duct 6 in the mandrel into the continuous extruded tube 7, and also from the teroidal ducts 10 on to the outside of the tube to cool it. The extruded tube is hauled from the extrusion orifice by a pair of nip rolls 5, which also collapse the tube as an air bubble is trapped between the nip rolls and the extrusion orifice. The apparatus is most suited to the manufacture of polythene films using a running temperature of 160 C. for the mandrel and 150 C. for the die.

Title: Synthesis of polymeric products
IPC: C08F6/02
Filed: 1964-10-26
Abstract: A process for the synthesis of polymeric products from ethylene, propylene or other alpha-olefins or mixtures thereof comprises polymerizing the alpha-olefin with a catalyst comprising titanium, zirconium, vanadium or aluminium or mixtures thereof in the presence of a diluent comprising propane, propylene or butane or a mixture thereof, removing said diluent from the resulting solid polymeric product, removing the catalyst residues from the solid product by de-ashing the product with a hydroxyl-containing reactant to react with and solubilize the residues in admixture with an aliphatic hydrocarbon having from 5 to 12 carbon atoms per molecule, and in the presence of an inorganic acid, the de-ashing being effected at temperatures within the range of from 190 to 250 DEG  F., and then separating the thus purified polymer product from the resultant reactant containing the solubilized residues. In the examples polyethylene and polypropylene, produced by polymerizing the monomers in butane using a titanium trichloride/aluminium triethyl catalyst, are de-ashed by treatment with an isopropanol/heptane/anhydrous hydrochloric acid mixture at various temperatures within the range specified above.  The de-ashed polymers may be for electrical insulators.  The atactic content of polypropylene is also reduced in the de-ashing process.

Abstract: 894,346. Transistor oscillator circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. MARCH 16, 1961 [Dec. 30, 1959], No. 44213/59. Class 40(6). An oscillator comprises an amplifier having shunt-fed negative feedback via a thermistor and positive feedback via a phase shifting circuit. Fig. 2 shows an oscillator comprising a pair of amplifiers each comprising transistors J3, J4 on the one hand and Jl, J2 on the other. Negative feedback is taken from the emitter follower J2 to the base of transistor J1. A positive feedback path is taken via C9, R6, R7 to the base of transistor J1. so that the system oscillates at a frequency dependent on the setting of the ganged switches S1, S2 and the ganged resistors R4, R7. The gain of the amplifier comprising transistors J3, J4 is automatically adjusted by the change in voltage across the thermistor 3 in the negative feedback path, so that the output is maintained constant over a frequency range from 20 c./s. to 200 kc./s. The thermistor 3 is operated at the peak of -its voltage / current characteristic. Distortion in transistor J1 is cancelled by that in J3. Series resistance/  capacitance stabilizing circuits may be connected across R1, R3.

Abstract: 949,119. Refrigerating. PETROCARBON DEVELOPMENTS Ltd. Dec. 19, 1962 [Dec. 21, 1961], No. 45892/61. Heading F4H. A refrigeration system comprises compressing helium in a two-stage reciprocating compressor 1, cooling the helium firstly in a water fed cooler 2, secondly by indirect heat exchange with returning helium in an exchanger 3 and thirdly by expansion in a radial inward flow turbine 4, then contacting the helium with an adsorbant 5, e.g. activated carbon, to remove nitrogen and oxygen, further cooling the helium firstly by indirect heat exchange with returning helium in a further exchanger 6 and secondly by expansion in a second radial inward flow turbine 7 to atmospheric pressure, using at least part of the helium to perform a refrigeration duty in a cold chamber 9 and returning the helium to the compressor 1 for recycling. Part of the helium by-passes the cold chamber 9 in a bypass line 10 containing a valve 11 controlled by a device 12 sensitive to the temperature at the inlet to the second turbine 7. A further bypass 18 around the second turbine 7 has a valve 19 controlled by a device 20 sensitive to the temperature of the cold chamber 9. In order to keep the downstream pressure of the first turbine 4 constant, a valve 21 is located upstream of the by-pass 18 and is controlled by a device 22 sensitive to the pressure at the discharge of the first turbine 4. A by-pass 23 to the compressor 1 is controlled by a valve 24 governed by a controller 25 sensitive to the inlet pressure of the compressor. A by-pass 26 to the first turbine 4 is controlled by a valve 27 governed by an element 28 sensitive to the temperature of the helium entering the adsorber 5. Part of the helium is withdrawn by a branch stream 14 before entering the second heat exchanger 6 and performs a cooling duty in a further cold chamber 16. The branch stream 14 is regulated by an expansion valve 15 controlled by a device 17 sensitive to the temperature of the helium leaving the further cold chamber 16. A manual valve 30 is provided to prevent the helium from passing through the second heat exchanger 6 and the second turbine 7 at starting until the adsorbant 5 is cooled to a temperature below 100‹ K. The turbines drive blowers 31, 32 which compress helium in a brake circuit and the compressed helium is fed to an external source 37 where the heat is removed. The helium is then returned to the blowers. A vent line 38 from the brake circuit includes a valve 39 controlled by a controller 40 to open when a desired adjustable pressure in the brake circuit is exceeded. Two separate brake circuits at different pressures may replace the single circuit shown. A small flow of helium flows from the turbine inlets to the bearings and then to the brake circuit. The Provisional Specification states that the helium compressed in the blowers is expanded through fixed orifices.
