Title: Method of charging electrical furnaces
IPC: F27D3/18
Filed: 1928-05-14
Abstract: 317,416. Mond, A. L., (I. G. Farbenindustrie Akt.-Ges.). May 14, 1928. Electrode furnaces.- To avoid segregation, the charge is supplied in a continuous stream, without coming into contact with the furnace walls, over adjustable guide surfaces which are arranged above the melting or reaction zone, and sloping in a direction towards the electrodes. The. surfaces mav be of cooled or uncooled, sheet metal or refractory brick, and, when in contact with the feed pipe 2, may have a triangular form 4<a>, Fig. 2, or, when a free outlet is provided for the charge from the pipes 2, the guides may be rectangular as shown at 4b, Fig. 2. With one electrode, the surface may consist of a closed truncated cone. Three partly open truncated cones interconnected at their points of intersection may be triangularly disposed in relation to three electrodes. To prevent premature lateral overflow, the surfaces may be concave or provided with a rim. Fig. 3 shows a three phase alternating current furnace in which part of the charge may be supplied through a central pipe 5, the guide surfaces for this pipe being dispensed with.

Title: Conversion of synthetic drying oils to thermo-setting resins
IPC: C08K5/14
Filed: 1957-05-03
Abstract: An oily polymer or copolymer of 100-50 per cent by weight of butadiene-1,3 and 0-50 per cent by weight of styrene is heated at 100-175 DEG  C. in presence of 2-7 per cent by weight of dicumyl peroxide to produce a solid insoluble, infusible, hard resin.  The oily polymer or copolymer may be produced as described in Specification 677,774.  Typical syntheses are: (A) butadiene-1,3, mineral spirits, t-butyl hydroperoxide and diisopropyl xanthogen disulphide are heated in a closed reactor and the oily polymer is separated by fractionation from low molecular weight materials; (B) 80 parts of butadiene-1,3, 20 parts of styrene, mineral spirits, dioxane, isopropanol and dispersed sodium are heated in a closed reactor.  The product is purified and fractionally distilled.  The styrene may be added after polymerization of the butadiene has commenced.  Preferably the curing temperature is slowly raised over a range.  A suitable heating schedule is 8 hours at 100-110 DEG  C., 24 hours at 110-120 DEG  C., 24 hours at 120-130 DEG  C., and 36 hours at 130-150 DEG  C.  Fillers, e.g. mica, asbestos or silica may be incorporated with the oily product to be cured.  They improve strength and thermal conductivity and shorten the curing time.  In Example 1 an oily copolymer of 80 parts by weight butadiene and 20 parts by weight styrene was mixed with dicumyl peroxide, cast in a shallow pan and heat for 5 days on a rising temperature schedule to form a hard polymer.  In Example 2 comparison tests using other percompounds as catalysts were shown to give unsatisfactory results.

Title: Digital position control device for machine tools and similar equipments
IPC: G05B19/35
Filed: 1965-04-05
Abstract: 1,105,442. Programmed control of machine tools. ING. C. OLIVETTI & C. S. p. A. April 5, 1965 [April 7, 1964], No. 14441/65. Heading G3N. In a programmed control system for a machine tool an arrangement is provided whereby the digital position signals, prior to being fed to a servosystem, are summated with a correcting constant, representative of the difference between a reference point on a workpiece and an absolute point on a worktable, derived by manually controlling the positioning of the worktable to coincidence. The programme is provided on a punched tape which is read to provide a sequence of signals from a decoder representative of the address of the sequence, the sense and digital magnitude of the desired position, the presence of a sprocket hole and end of sequence. The magnitude signals are fed to an adder wherein they are summated with the correction signals and fed to a diode matrix memory circuit. The address signals through a logic network control the memory, the sequential read-out of the correction signal and the initiation of the positional error correction by the servosystem. The correction signal is set up on a plurality of manual decade switches, sequentially selected by a relay chain. Provision is made for manual positioning by a further plurality of decade switches. The summated position signals are fed from the memory through a digital to analogue converter to the movable winding of a transformer position sensing device, the error signal from which controls the servosystem.

Title: Improvements in or relating to apparatus for joining thermoplastic material
IPC: B29C65/00
Filed: 1946-05-14
Abstract: 635,549. Seaming non-metallic sheets. MILNE, J. T. G. May 14, 1946, No. 14490. [Class 42 (i)] [Also in Group XXXVIII] Apparatus for joining thermoplastic material by heating it with radio-frequency oscillations comprises means for advancing the material and means for automatically varying the power of the oscillations in dependence upon, and in the same sense as, variations in the volume of material to be heated in a predetermined interval of time ; the power may be varied according to the rate of travel of the material, or its thickness, or both. To vary the power of the oscillations in accordance with the speed of travel of the material, this is passed between electrodes 1 and 2, driven in opposite directions electrode 1 being connected to an oscillator 3, and electrode 2 earthed. Electrode 1 is mounted, through an insulator 34, on a shaft 9 which has pin-and-slot connection with a shaft 8 carrying a disc 7 frictionally driven by a disc 5, itself driven, if desired, through reduction gearing 6, from a constant-speed electric motor 4. The shaft 8 is mounted for axial movement, thus causing the radius at which the disc 7 contacts the disc 5 to vary, under the influence of a bar 15 to which it is connected by a thrust coupling 17. A pedal 13 operates through linkage 14 on the end of the bar 15, which carries a rack 18 engaging a pinion 19 operating an adjustable transformer 20 connected in the supply leads to the high-tension transformer of the oscillator 3. A cam mechanism may be inserted between the bar 15 and the adjustable transformer 20 to secure a non- linear relation between the speed of the rollers 1 and 2 and the heat developed. In place of the transformer, an adjustable condenser or inductance may be used for controlling the oscillator output. To vary the power output according to the thickness of the material, the roller 2 may be journalled on a spring-loaded bearing 23 which is connected to one end of a lever 25. The other end of lever 25 is situated between pairs of contacts 26, 27 mounted on a nut 28 running on a threaded spindle 29 geared to a split field motor 30 which is connected to the pairs of contacts 26, 27 in such manner that when either of these is closed,-the motor operates to move the nut 28 until the contacts open again. The motor 30 is also geared to an adjustable transformer 33 which controls the amplitude of the oscillations. Multiplying link mechanism may be used in place of the simple lever 25, and an adjustable condenser or inductance may be used for controlling the power of the oscillator in place of the variable transformer. The rollers 1, 2 may be replaced by a single roller and a stationary foot, or a pair of electrodes in the form of feet may be used which move towards each other, press and forward the material. Specification 599,894 is referred to.
