Title: A method and an electro smelter for producing porcelain enamel
IPC: C03B5/027
Filed: 1952-03-28
Abstract: 714,292. Glass melting furnace. THORNTON, A. A. (Ferro Enamel Corporation). March 28, 1952, No. 8013/52. Class 51 (2). [Also in Group XI] Porcelain enamel frit is produced by feeding a dry mixture of raw materials continuously in a thin layer on to the outer end of a deep bath of the mixture in a melting chamber 1 where it is heated by current passing transversely therethrough between opposed deeply immersed electrodes so that convection flow takes place in the bath due to temperature differences in vertical parts thereof, skimming back at 6 the surface of the bath as it flows to a second bath 10 which is shallow and wherein smelting is completed by passing current between three vertical electrodes B, the smelted enamel passing through a submerged passage 24 to a firing chamber 18 in which current is passed transversely through the enamel between submerged electrodes C in opposed walls, the enamel being finally delivered at 27 under fritting conditions. The group of electrodes in each chamber is supplied 'rom a separate power source The smelting chamber 10 is at a higher temperature than the melting chamber 1. The three electrodes B in the smelting chamber are equi-distant from one another so that a hot spot is created in the enamel at the centre between the electrodes thereby causing a circulation of the enamel. The smelting chamber 10 has adjacent the firing chamber a chimney 15, which draws gases through a passage 25 from the firing zone and tends to draw hot gases from the me'ting and smelting zone in the direction of flow of the enamel. The skimmer 6 is water-cooled. The wall 17 of the melting chamber slopes up to the smelting chamber 10. The electrodes A, C are metal plates on opposed walls, through which water-cooled contact arms pass. The electrodes should be of material lower in the electromotive series than the metals the oxides of which are in the raw batch. Graphite electrodes may be used, and if the batch contains much zirconium, the electrodes may be of molybdenum. Specification 683,701, [Group XI], is referred to.

Title: Radar simulation apparatus
IPC: G09B9/54
Filed: 1971-03-31
Abstract: 1383325 Radar simulators; sawtooth wave generators; analogue gates REDIFON Ltd 2 March 1972 [31 March 1971] 8280/71 Headings H4D and H3T In radar simulation apparatus several display units, representing radar displays on independently moving vehicles, are time multiplexed to a single computer and target echo generator system. Data relating to vehicle movement is entered into computer 1 by keyboards 27.1 to 27.12, corresponding to displays 6.1 to 6.12, via interface 26. The computer converts vehicle control parameters, e.g. rudder angle, rate of climb, dive &c. into corresponding polar position co-ordinates and also generates the signals for simulated scanner rotation. The computer feeds a processing system 3 via interface 2, the interface containing separate registers for display address, display deflection, and target data code words. The processing system decodes the display address data and provides enabling pulses to multiplexer switches in unit 5, converts the display deflection code words to analogue voltages for the display sweep coils, and mixes the target data to provide a complex video waveform corresponding to several targets on the same bearing. The system described can simulate up to ten such targets. Unit 5 comprises analogue switches for sequentially feeding the display sweep coils and digital switches feeding the display bright up circuits to indicate targets. The display units have controls for selecting the scale or range of the display, this information being fed back to the computer over lines 24 so that the data may be appropriately modified. Sawtooth wave generators, Fig. 7.-The displays are P.P.I.s using resolved time bases fed by generators 43, 43<SP>1</SP> corresponding to North and East components. D.A.C.s 1, 2 give the analogue components of the scanner azimuth angle. The D.A.C.s are connected to Miller integrators 70, 71 which integrate the D.A.C. outputs to give signals of a polarity and final magnitude dependent on the D.A.C. outputs. Switches or analogue gates 74, 75 are switched on by timing pulses RMSTP+ to shunt the D.A.C.s and reset the integrators.  Analogue gates, Fig. 8.-Fig. 8 illustrates detailed circuitry of the analogue switches or gates. The gate control is applied at terminal 81. This controls the off or on state of a metaloxide silicon f.e.t. 80 via transistors 84, 85, 86.

Title: Bale tying mechanism
IPC: A01F15/14
Filed: 1976-03-02
Abstract: 1522071 Baling presses DEERE & CO 2 March 1976 [3 March 1975] 8341/76 Heading B5F In a bale wiring or twining mechanism bales of substantially constant pre-determined length are ensured by anti-bounce device associated with a stop for determining the lowest position to which a trip arm 40 associated with a metering wheel 50 drops to re-set the trip arm for the next bale. The mechanism is mounted on the bale case 10 with the star wheel 50 measuring the forming bale and raising the trip arm 40 about a pivot 42 by contact with a wheel 56 driven by the star wheel 50 and an arcuate track 46 carried by the trip arm. The pivot 42 is on a lever 3 fixed to a shaft 28 which is also fixed to two arms 26, 32 so that when a pocket 48 in the rising track 46 encounters the wheel 56 the shaft 28 is turned anti-clockwise by a spring 34 on the arm 26, thus releasing a pawl 24 to engage a one-revolution clutch 18. The driven member 22 of the clutch, through a crank arm 30, drives a lift link connected to a needle frame (not shown). A cam surface 33 on the driven member 22 engages the arm 32 turning it clockwise and displacing the track 46 to the right so that it drops until arrested by contact between an adjustable stop 20 on the track and discs 60, 62 on each side of the wheel 56. Bounce of the stop 20 is prevented as a tong 74 projecting from the stop is frictionally gripped between the disc 60 and spring-pressed disc 62. Continued rotation of the driven member 22 clear of the arm 32 allows a spring 34 to return the arm 26 into position for stopping member 22. The resulting rotation of shaft 28 pulls the wheel 56 against the track 46 for the next measuring stage.
