Filed: 1972-03-30
Abstract: 1399654 Extrusion dies OMEGA PLASTICS Ltd 28 March 1973 [30 March 1972] 15143/72 Heading B5A An extrusion die which enables foamed polystyrene sheeting having a thickness of less than 0À010 inch and a weight of less than 30 grams per square metre to be formed, comprises a torpedo which is held to the die body by a perforated breaker plate 9 and which includes aligned bores 24, 25 that co-operate with a bore 26 in the outer ring of an air spacing ring 8 and with a bore 27 in a tube 28 to allow pressure air to pass through the die and inflate the extruded tube. The torpedo comprises a bullet-shaped upstream part 17 and a downstream part 18 which are screw-threaded together and to the breakerplate 9. The latter comprises two rings of perforations 30. Immediately downstream of the breaker-plate 9, the torpedo and die body 1 taper towards each other, i.e. 31, 32, to form a throat section 33. Further downstream the torpedo tapers more than the body to form a section 35 which increases in radial width in a downstream direction. Passage of molten polystyrene which includes a blowing agent, through the throat section 33 and section 35 gives rise to a turbulence which together with passage through the breaker-plate 9 destroys the rotational motion of the material due to the screw (40, Fig. 2). The torpedo includes an extension which carries an adjustable sleeve 19 which has a lip 20 which co-operates with a lip 14 of the die body to define an annular die outlet. The extruded tube is passed through a collapsing screen 48 of rollers, a set of draw-off rollers 49 which roll the tube flat and an edge slitter 50 to a wind-up station 51. The extrusion die is also provided with a wire screen filter pack 5 and is surrounded by a cooling water jacket to provide a die body temperature of 260- 280 F.

A slide rule for evaluating the heat transmission formula employed in calculations relating to lagged pipes, comprises separate groups of scales and slides for evaluating the two components of the denominator, and a third group of scales and slides for then evaluating the formula. The rule comprises seven slides working in four slots in a base, six of the slides being disposed in contiguous pairs. Scales for the factors of the above formula, and intermediate result factors X and Y representing the two components of the denominator, are marked on the slides and base as indicated at the right-hand side thereof. The three upper slides B, F and G are employed to evaluate X and the next two slides L and K to evaluate Y, result values being shown at the adjacent two centre scales H, M marked on the base. Using the sum of these values, heat loss per square foot q is -read on scale Q using slide O and scale N. Alternatively, heat loss per foot length of pipe can be ascertained by employing the d<SP>1</SP> scale of slide P in conjunction with slide O. A simpler formula for heat transmission through flat insulated surfaces can also be evaluated by the rule. All of the scales are logarithmic to the base 10 except for scale D, which is linear corresponding to the logarithmic C scale. Scale E is logarithmic, and of like units to scale C, but displaced from the result scale H by the Napierian constant 2.302.

Abstract: 776,281. Electric measuring systems. IMPERIAL CHEMICAL INDUSTRIES, Ltd. April 26, 1955 [May 26, 1954], No. 15565/54. Class 40 (1). [Also in Groups XXXV and XL (c)] A remote indication of the position of a lever 15 is obtained by coupling the lever 15 by a spring 14 to a lever 11 which differentially adjusts a pair of condensers C<SP>2</SP>A, C<SP>2</SP>B. The values of these condensers determine which one of two oscillators V<SP>1</SP>A, V<SP>1</SP>B is oscillating and which is not, so as to control (see Group XXXV) the current passed by either rectifier RECT (1) or RECT (2). This current is measured by a milli-ammeter 16 to provide the output indication. The output current is also passed through a coil 12 secured to the lever 11 so that in cooperation with a magnet 13 it tends to cancel the initial movement of the lever. The oscillator may be replaced by any one of those shown in Figs. 3 to 7 (not shown). In another embodiment, Fig. 9 (not shown), movement of the input lever adjusts the position of the core of a differential transformer thus varying the magnitude and phase-sense of the input signal to a phase-sensitive rectifier (see Group XXV) the output current of which is measured to give the required remote indication. The output current is fed back to a coil on the input lever as before.
