Title: Automatic machine tool
IPC: G05B19/18
Filed: 1963-02-15
Abstract: 968,168. Programmed control of machine tools. HUGHES AIRCRAFT CO. Feb. 15, 1963 [Feb. 28, 1962 (2)], No. 6238/63. Heading G3N. In a programmed control system for a tapping machine, signals from a programme unit 45 are fed to a digital to analogue converter 85, comprising a relay-switched attenuator, supplied from a constant voltage source 87. The output from the convector is fed to a controller 21 which, through gearing, rotates a tapping spindle 22. A tachogenerator T2 is mechanically coupled to the spindle and generates a voltage which is attenuated by a variable impedance network 28, comprising relays controlled by the programme unit 45 to derive an output signal representative of the programmed relationship between spindle rotational speed and spindle travel. The output signal from network 28 controls a lead-screw 30 through a control unit 88, hydraulic servo-valve 37 and hydraulic motor 32. Feedback is applied to the control unit 88 from a tachogenerator T38 driven by the spindle 30. A position transducer P40 senses increments of rotation of the lead-screw and counts-down a binary counter 91, preset by the programme unit, which at a minimum count actuates a switch (not shown) to reverse the signal to the controller 21 and change the direction of rotation of the spindle 30. The output of the tachogenerator T27 is according- ly reversed and consequently the direction of tool travel. In a modification, a voltage-trimming unit is actuated by a spring-positioned tap-holder, Fig. 6 not shown, to adjust for differences between the programmed relationship between rotational speed of the spindle and the rate of advance of the spindle and the tap-pitch.
Patent GB-717576-A (GB)
Title: A process for reducing powdery ores without a previous agglomeration
IPC: C21B15/00
Filed: 1951-03-15
Abstract: A process for reducing powdery ores without agglomeration is carried out in an open furnace by preparing in the furnace a layer of molten salt (or salts) or molten slag, which is maintained at a suitable temperature by means of an electric current following a substantially horizontal path through a slag resistance, pouring on to the molten bath a mixture of powdered ore and coal and slag forming or corrective substances to form a layer of as far as possible uniform thickness on the bath.  The mixture is dried by heat from the bath and the reduction is started and completed as the materials are brought to fusion and are absorbed in the bath in the form of droplets.  The gaseous products pass through the charge layer which they heat, and leave the furnace at a low temperature (e.g. 50-150 DEG C.).  The slag and molten metal formed settle and are withdrawn at intervals to maintain their thicknesses within desired limits.  In an example the charge comprises 65 per cent. of ore (iron oxide with an Fe2 O3 content of about 80 per cent.), 20 per cent. coal and 15 per cent. of limestone (with 96 per cent. CaO) together with a small amount of pyrolusite and forms a layer on the bath of about 30 cms. The bath temperature is kept at about 1500 DEG C.

Title: Improvements relating to the production of artificial threads and filaments by the viscose process
IPC: D01F2/06
Filed: 1959-02-24
Abstract: In the spinning of viscose, the thread is withdrawn from the coagulating bath by a lower draw-off roll from which, after passing upwardly through a short air gap (preferably of 3-15 cm.), the thread is drawn over a fixed thread guide, e.g. a non-rotating rod or pin, which is not submerged in a liquid, and is thereafter drawn under a second fixed thread guide, for example a non-rotating rod or pin, which is submerged in a hot dilute aqueous solution of sulphuric acid contained in a vessel to which hot water is continuously supplied. The thread is then withdrawn from the acid solution through a relatively long air gap by an upper draw-off roll, the peripheral speed of which is higher than that of the lower draw-off roll so that the thread is stretched during its passage through the hot acid solution, and the thread is finally taken to a centifugal spinning pot in which it is collected.  The non-rotating rods or pins may be of glass or ceramic material.  In the illustrated example, the first thread guide is rigidly fixed to one of the upper edges of the vessel containing dilute sulphuric acid at about 95 DEG C., and the submerged guide is fixed to the bottom of the vessel but is pivotally mounted to facilitate threading-up.  The vessel is provided with an overflow weir so that the level of liquid remains constant.  The rate of supply of hot water to the vessel is so adjusted as to maintain a constant concentration of acid, the more concentrated acid carried by the thread from the coagulating bath being diluted in the vessel by the hot water continuously supplied.  The thread may be stretched 80-140% preferably about 110% during its passage through the liquid in the vessel.
