Title: Improvements in or relating to method and equipment for moulding articles from nylon
IPC: B29C45/03
Filed: 1951-07-11
Abstract: 705,607. Moulding polyamides. POLYMER CORPORATION. July 11, 1951 [July 27, 1950], No. 16418/51. Class 87 (2) Consists of improvements in the apparatus of Specifications 641,647 and 656,725 for moulding rods and slabs of nylon, according to which the nylon is melted before being charged into the cylinder 10 to which the mould is subsequently attached. The cylinder 10, Fig. 2, previously heated and swept out with an inert gas, is suspended by means of screws 27 in. a heated container 24 which may be raised or lowered by means of a jack 26. The cylinder is closed at the bottom and the top by discs 11, 12 made of metal having a higher coefficient of thermal expansion than the metal of the cylinder. The upper disc 12 has a central orifice which, during the charging, registers with one of a pair of nozzles 2 connected to a heated screw-extruder 16. Flow of molten nylon from the nozzles is controlled by valves 23. The nylon is at a temperature somewhat above its melting point. The charged cylinder 10 is associated in the manner shown in Fig. 1 with a pre-heated tubular mould 31 having a pressing plunger 32 and an internal sliding plug 35 which has a coefficient of thermal expansion higher than that of the mould tube. The assembly is positioned between the plunger 34 and the bed 33 of a hydraulic press and the disc 12 is driven downwards into the cylinder. The cylinder 10 contains an excess of material which is maintained in the molten condition by a heater 37 and serves to keep the material in the mould under pressure whilst it cools. The alternative form of moulding apparatus shown in Fig. 5 is similar to that of Specification 656,725, the main difference being that the cylinder is associated with a group e.g. three, of tubular moulds 42 which are screwed into a sliding plug 43. The assembly is supported on the bed 45 of a press by means of a sleeve 47 and the bed has an aperture 46 through which the mould tubes 42 may extend downwards. Pressure applied by the press plunger 48 serves to force the cylinder 10 downwards over the stationary plug 43. Slidable plugs 52 in the mould tubes have air-vents 53. Fig 9 shows another form of moulding apparatus in which the container 10 is closed at the bottom 6y a flanged disc 56. having a nozzle 57. and by a thin breakable diaphragm 58. During filling, the cylinder is closed at the top by a flanged and apertured disc similar to disc 56 which is replaced during the moulding step by a slidable plug 61. The mould, consisting of wedge-shaped halves 64 arranged in a heated mould block 67 is placed on the press bed 68 and pressure brought to bear on the plug 61 by means of plunger 62. In an alternative arrangement, Fig. 10, the cylinder 10 is closed during charging by apertured plug 70 held in position by screws 27. During moulding the screws are loosened and a plug 72 superimposed on the plug 70.

In a marker apparatus for agricultural machines two markers 38, 39 carrying ground engaging discs 41 are pivotably connected to the main frame 12 which may be towed by a tractor via bail 30. Normal to the forward marker arms 44, 46 are attached lever arms 52, 53 with crosspieces 52a, 53a. A castor wheel 28 on the implement is rigidly secured to a laterally swingable actuator arm 35 flexibly connected near its free end to the lever arms 52, 53, for example by cables or chains. As the implement is turned towards the ground-engaging marker 38 the castor wheel swivels causing the arm 35 to swing laterally, abut the cross-piece 53a and push the marker 39 into an operative, ground-engaging position. At the same time the arm lifts marker 38 into an inoperative position by pulling on chain 55. A marker may be provided at each end of a gang of laterally interconnected implements, both markers having an actuator arm and castor wheel. In a modification the two markers 38, 39 are interconnected by a flexible cable (60), Fig. 5 (not shown), which is connected to an adjustable actuator arm 35 so that as the arm moves laterally, the cable (60) is moved to lift one marker whilst allowing the other to drop to its operative position. This actuator arm may freely pivot in a vertical plane between stops (84), (86), Fig. 6 (not shown), so that the castor wheel can be turned through an angle greater than 90 degrees. Two castor wheels may be provided in this arrangement, with both actuator arms acting on cable 60.

Title: Improvements in or relating to cathode ray tubes
IPC: H01J29/46
Filed: 1952-07-02
Abstract: 721,566. Cathode-ray tubes. RAULAND CORPORATION. July 2, 1952 [July 3, 1951]. No. 16638/52. Class 39 (1). A cathode ray tube, preferably a picture reproducing tube, comprises cathode 13, control electrode 14, first and second accelerating electrodes 15, 16 and a " unipotential " electrostatic lens 17, 19, 20 as described in Specification 715,235, the outer lens electrodes 17, 20 are connected by way of a wall coating, and the connections 22, 23, preferably metal springs, are disposed outside the space bounded by planes perpendicular to the tube axis and containing the most proximate portions of electrodes 17, 20. This avoids the presence of a transverse field component due to slight asymmetries in the arrangement of the metal strips connecting the outer lens electrodes in Specification 715,235. The second anode 16 is offset from first anode 15 to provide in conjunction with permanent deflecting magnet 27 an ion trap. Magnet 27 is carried in spring clamp 28 and is axially and rotationally movable. A fluorescent coating 29 indicates correct setting of the ion trap. The gun electrodes are all tilted with respect to the tube axis by the same angle. Metal springs 22, 23 also serve as spacing and centering devices. Lead 24 to lens electrode 19 has glass beading to prevent sparking to 21 or 16. The electrodes are all carried by two glass pillars 26 (only one shown) and coating 21 has a contact button terminal (for a glass envelope) or a metal cone envelope portion may serve as a terminal. Getters 30 are supported from electrode 20. The voltage of electrode 19 may be adjusted for focussing or to compensate for slight misalignment of the electrodes and in general varies between cathode (earth) potential and the relatively low D.C. supply voltage. If the ion trap is not precisely adjusted astigmatism and/or coma results in the focussing, due to the beam approaching the focussing system at an angle to the axis or off centre. The fluorescent coating 29 may alternatively be on diaphragm 17 or 20 or on the tube wall near the gap between 15 and 16, and the glow therefrom is visible directly or by reflection through the neck 12. Electrodes 17, 20 have corona rings 31, 32 of stainless steel welded thereto, and electrode 19 is a metal cylinder 33 the ends of which are rolled over the edge of a metal disc 34; this construction also provides mechanical strengthening. Jigs are used to assemble the electrodes and other jigs orient the gun in the tube neck. The ion trap may alternatively employ co-axial electrodes with a slanted aperture between two of them, but this is not preferred since it introduces elliptical distortion in the focussing. Specifications 678,546, 679,348 and 685,821 are also referred to.
