Title: Grain drier
Inventor: BURGHARD STEPHEN FREDERIC
IPC: F26B17/12
Filed: 1966-07-05
Abstract: 1,200,731. Treating grain. JOHN WILDER Ltd. 5 Oct., 1967 [5 July, 1966], No. 30072/66. Heading A2Q. [Also in Division F4] A continuous grain dryer has means to control the flow of grain automatically to one of two rates of discharge or flow in response to the temperature of the dried grain or the temperature of the drying air as it leaves the dried grain, the two rates being a low mean rate (including zero) and a high rate. Thus the temperature-sensing device 15 permits the grain to flow freely so long as the emerging grain is dry, but stops or reduces the flow to a low rate if the emerging grain is still wet. Wet grain flows by gravity between the perforated walls 10, 11 through a drying zone 12 in which hot air passes through the grain and is extracted from the centre, then through a cooling zone 13 in which cold air passes through to the centre. Discharge is controlled by a mechanism 14 controlled by temperature sensitive device 15. Fig. 2 shows a suitable control circuit. The temperature sensitive device moves contact 17 to 18 when the grain is dry and to 19 when a lower temperature indicates that it is still wet. For dry grain and switch in position 18 current flows through coil 6 which opens discharge mechanism 14 to give a full rate of flow. With still wet grain and switch in position 19, timer motor 20 is energized, which closes contacts 21 for a pre-determined time in each cycle of the timing gear, e.g. for 2 minutes in every 5 minute cycle. When the contacts are so closed, coil 16 is energized to open discharge mechanism 14 for the predetermined proportion of each cycle, which continues until the slow moving grain is dry and the temperature rises sufficiently to operate switch 17 to reinstate full rate of discharge.

Abstract: 1,271,587. Valves. SINGER CO. 22 June, 1970, No. 30266/70. Addition to 1,142,678. Heading F2V. A pressure regulator comprises an inlet 1, an outlet 2, and a compound valve member 45 which is repensive to movements of a diaphragm 4 the underside of which is open to the outlet, the valve member being formed of two relatively movable parts, 41, 42 and 49, 46, 47. The first part 41, 42 is connected to the diaphragm and carries an annular sealing ring 43, whilst the second part 49, 46, 47 is slidably mounted on the first part, engages the sealing ring 43 and with the first part defines a chamber 51 which is in permanent communication with the inlet 1 via a passage 50. A wave spring 53 is interposed between the two parts and acts to urge the second part 49, 46, 47 away from the valve seat 26. In use, surges at the inlet tend to move the second part of the compound closure member towards the inlet by virtue of the pressure differential created across member 49 of the second part 49, 46, 47, whilst variations in force of the diaphragm and spring assembly 4, 5 due to changes in position after assembly are compensated for by the wave spring 53.

In a modification, a lamp having two annular anodes is eccentrically arranged in a Dewar flask-like vessel. In another modification, Fig. 5, two series connected lamps 12, 13, which may be combined to form a single U-shaped lamp and have a diameter of 25 mms., are spaced 2 mms. apart in an outer envelope 16.

Filed: 1961-08-24
Abstract: 969,038. Bobbins. EASTMAN KODAK CO. Aug. 24, 1961, No. 30506/61. Heading B8M. A spool-forming device comprises a flange-carrying hub 13 on which is positioned a resilient ring 15 which, upon axial insertion of the hub into one end of a core 11, rolls on the hub 13 to become compressed between the hub and the inner surface of the core 11 to retain the device in position. In the embodiment shown in Fig. 1, the hub 13 having a flange 14 is extended to form a shaft 12 on which a second hub 16 having a flange 17 is slidably and detachably mounted. Resilient rings 22, 23 are loosely accommodated in grooves 20, 21 respectively prior to insertion of the hubs 13, 16 into the core 11 and their external diameters are greater than the internal diameter of the core. The hub 13 is first inserted into the core 11 and then the hub 16 is positioned on and slid along the shaft 12 into the core. When the cross-section of either ring 22 or 23 has rolled through more than an odd number of half-rotations but less than the next larger even number of halfrotations, a force is exerted on the hub 13 or 16 tending to draw it further into the core. Collars 29, 30 prevent the removal of the rings. Apertures 26, 27 are provided to enable the spool to be mounted on a spindle. Alternatively, axial pins to engage trunnions may be provided. In a modification, Fig. 2, two identical spoolforming devices are provided, one at each end of the core. The devices may be used to form film spools in which the edge of the roll of film 10 may be flush with the core 11 or project therebeyond, Fig. 1, or the core 32 may project beyond the film, Fig. 2.

Title: Method and apparatus for arc welding
IPC: B23K9/127
Filed: 1976-07-22
Abstract: 1514407 Automatic control of welding P PUSCHNER 22 July 1976 [25 July 1975 20 Oct 1975] 30656/76 Heading G3R The position of a welding torch relative to a joint being formed between the edges of two workpieces is controlled in accordance with measurements of characteristic values of arcs struck between the torch and different zones of the workpieces. The measurements are combined and compared with a reference value to produce a signal which is used to adjust the torch position. As shown in Fig. 5, a consumable or non- consumable elctrode 11 passes through a welding torch 10 to form a seam weld between workpieces 14, 15. The torch is moved along the seam by a motor 16, and its position can be adjusted laterally and vertically by servomotors 12, 13 controlled by circuits 32, 33. Welding current is supplied from a source 26 powered by the mains 24. A transducer 31 senses the welding voltage and current passing through a shunt 28, and operates in a cyclic manner determined by a thyristor pulse generator 25 which also controls a circuit 23 supplying energizing current to windings 21 on a yoke 20. The windings 21 produce a magnetic field which deflects the welding arc on to each of the workpieces 14, 15 in turn for a fraction of each supply cycle determined by thyristor phase control. The transducer 31 is synchronized with the deflection of the arc so that it senses and stores signals corresponding to the difference between voltage and current signals when the arc is directed on to each workpiece respectively. After integration, the signals for the two workpieces are summed and differenced in circuits 33, 32 to form signals for controlling the vertical and lateral positioning of the torch 10. In another embodiment, Fig. 7 (not shown), two electrodes are used, producing arcs simultaneously at each workpiece, and the currents flowing in each electrode are compared to produce control signals. Instead of current and/or voltage, other arc characteristics may be monitored, such as radiation, colour temperature or noise.

[Also in Groups V and VIII] A radome is made of radiation transparent material reinforced by metal contained within the radome walls. In one embodiment a conical radome is made from two or more sheets of glass fibre material impregnated with a thermosetting resin. These are cut to sector shape and are assembled one on top of the other with steel reinforcing strips 11 between them. These strips, which are preferably of bowed cross-section to give additional strength, are arranged to lie radially with respect to the centre 13 of the sector. In order to provide a fairly even strip spacing only a limited number of strips 11 A approach the centre 13, at a point one-third of the way out further strips 11B are added mid-way between the strips 11 A, and two-thirds of the way out additional strips 11C are inserted between the strips 11A and 11B. The flat assembly of sheets with the reinforcement in it is then rolled into conical form and the moulding and curing of the resin completed. To further strengthen the radome so formed eight circumferential stiffeners 15 of graded sizes are secured at equal intervals along its inside surface. These are channel-sectioned rings of moulded fibre glass material having flanges 16 bonded to the wall of the radome by the curing of the resin. Instead of using a plurality of strips to reinforce the radome a thin steel plate having a large number of apertures of suitable shape and size may be employed.
