IPC: B29D30/06
Filed: 1960-09-20
Abstract: 988,081. Moulding tyres. DUNLOP RUBBER CO. Sept. 7, 1961 [Sept. 20, 1960], No. 32211/60. Heading B5A. In a rayon or nylon reinforced tyre, buckling caused by the heat-shrinkage of the nylon reinforcing material, is reduced by removing the tyre from the mould whilst the tread portion is still plastic, inflating it, and then compressing the side walls between press platens. The tyre is removed from the press, when the rubber has cooled. In the case of a nylon reinforced tyre the rubber must have cooled to a temperature below which no heat shrinkage can occur before it is removed from the press. In one modification the platens of the press and the outer walls of the rubber tyre afford an airtight seal and the tyre is inflated whilst it is held fast by the press. In a further modification the head of the tyre engages with a projection on the platen to form on airtight seal.

Title: Automatic steering gear for ships
IPC: G05D1/02
Filed: 1969-06-26
Abstract: 1279005 Automatic steering control LICENTIA PATENT-VERWALTUNGS-G m b H 26 June 1969 [26 June 1968] 32409/69 Heading G3R In an automatic steering system for ships having an integrating channel 11 in parallel with a proportional and differenting channel 13, 14, the course error signal ## is integrated continuously but the P.D. channel includes a device 15 which blocks this channel until the error exceeds a variable threshold, whereupon it remains open until the error drops below a smaller threshold value. The thresholds are adjusted according to the number of corrections that are made in a predetermined time, by an arrangement in which operations of a rudder adjusting trigger switch 19 are differentiated at 23, integrated at 24 and counted at 25, the count being compared with a predetermined number set at 26. The integrator 11 is followed by a limiter 12. The I. plus P.D. signal is amplified and filtered by an amplifier 16 whose gain is adjusted according to the response of the ship to rudder adjustments, made by devices 17, 18. As shown, the actual response of the ship, (represented by boxes 20, 21) in terms of angular velocity w ist (detected by a gyroscope) is compared with a corresponding angular velocity signal # soil produced by a "model" of the ship 27, 28; any difference ## varies the gain of 16. The actual ship's angular velocity is integrated at 22 to provide the actual course signal # ist which is compared with desired course # soll to produce the error signal ##. In an alternative embodiment, shown in broken lines and in Fig. 2 (not shown), the gain of 16 is adjusted in response to the difference between the actual value of the ship's angular velocity and the value this should have as determined by the setting of the rudder angle #ist. In this case the comparison is made when these values are steady and they are separated in time by an amount corresponding to the response time of the ship. A second threshold device may be inserted in this gain control channel. The gain may be adjusted by different amounts for port and starboard errors.

Title: Improvements in the conversion of copper-containing sulphide ores
IPC: C22B15/06
Filed: 1947-12-09
Abstract: 650,048. Extracting metals; treating ores. DUFFIELD, F. L. Dec. 9, 1947, No. 32494. [Class 82(i)] [Also in Group XII] Copper-containing sulphide ores are converted to blister copper by utilizing the heat of combustion of the sulphur and of the oxidation of any iron contained in the ore to convert the copper sulphides first to white metal and thence to blister copper, the action being carried out in a single horizontal cylindrical furnace, the sensible heat of the gases produced being applied to the ore charge prior to conversion. The ore, initially in a finely divided state may be agglomerated into lumps by the applied sensible heat and charged in its hot state to the converter. Ore mixed, where necessary, with fluxes such as silica is fed continuously to an agglomerating grate C, Figs. 1 and 2. The product from C is fed to a second moving grate E and from it directly to converted A over shoot E<SP>1</SP>. Feeding to the converter is interrupted only during pouring of slag from the converter and during the ultimate period of blowing the accumulated white metal to blister copper. During this latter period the movement of the grate E is reversed and preheated agglomerated ore is thus stored on grate E until such time as a fresh charge is required in the converter.
