Title: Improvements in and relating to extrusion machines
IPC: B29C48/06
Filed: 1955-08-31
Abstract: 810,287. Extrusion machines. CONTE. Aug. 31, 1955 [April 5, 1955], No. 21546/58. Divided out of 810,285. Class 87(2). A machine for the simultaneous extrusion of two materials, particularly for extruding pencil lead and a surrounding sheath in the manufacture of pencils, comprises two coaxial extrusion dies 28, 30 and two distinct oppositely threaded feed worms 24, 25 on the outer surface of a cylindrical body 23 rotatably mounted on a cylindrical core 22, the worm 24 being arranged to feed one material, e.g. a pencil sheath composition, to the die 30, and the worm 25 being arranged to feed the other material, e.g. a pencil lead composition, to the die 28 through an axial bore 21 in the core 22. The body 23 is rotated by means of a pinion, worm wheel, or pulley 33. The pencil lead and pencil sheath composition is fed from supply tubes 37, 38, respectively, containing feed worms 39, 40 or feed pistons. The worm 25 feeds the lead composition to the bore 21 through radial bores 271 in the core 22. Further radial bores 27 provide passages for the lead composition so that it may lubricate the inner surface of the body 23. The core 22 has threaded ends, one end receiving the die 28 and the other a plug 29, a pressure gauge or a feed hopper for prefabricated leads to be reinforced by the lead composition fed through the bores 271. The pencil sheath material extruded through the die 30 surrounds the lead extruded through the die 28, and the sheathed lead is extruded through nozzle 42 attached by a nut 41 to the die 30. The nozzles 28, 42 may thus be changed for others of different dimensions, and the body 23 and the core 22 can similarly be changed. In addition the body 23 may be made in two parts coupled together by dogs at approximately the central plane of the driving member 33.

Title: Improvements in or relating to the production of refined iron steels and alloy steels
IPC: C21C5/56
Filed: 1939-07-25
Abstract: 533,150. Iron and steel alloy steels. LOW MOOR ALLOY STEEL WORKS, Ltd., and NESFIELD, A. C. July 25, 1939, No. 21576. [Classes 72 and 82 (i)] In the production of refined iron which may be used for the manufacture of steel and alloy steels a pig iron is first melted in a furnace, preferably a reverberatory furnace, some of the impurities being removed by slag action, and then other impurities other than carbon, e.g. silicon and manganese, are removed by blowing a stream of oxidizing gas across the surface of the metal to remove the slag and oxidize the silicon and manganese, the blast being stopped prior to the removal of the carbon., A portion of the charge is then removed and transferred to a second furnace, preferably an open-hearth furnace, the carbon being removed from the charge maintained above its melting point by reaction with iron oxide, which may be incorporated in the housing, in a reducing atmosphere with the charge out of contact with the flame. The charge in this furnace may be puddled or stirred. :Before the transfer of this portion from the first furnace, a fresh charge of pig iron, to replace this portion, is preheated and then charged into that furnace after the removal of that portion. The refined iron may be converted into steel or alloy steel by the addition of carbon or alloying ingredients, such as chromium, nickel, molybdenum or tungsten.

Title: Digital plotter
IPC: G06K15/22
Filed: 1969-04-29
Abstract: 1,240,362. Graphical plotter. ELECTRONICS ASSOCIATES Inc. 29 April, 1969 [30 April, 1968; 3 Dec., 1968], No. 21733/69. Heading G4H. In graphical plotting apparatus, with coefficients x 0 , y 0 ; x 1 , y 1 ; x 2 , y 2 ... through which the pen is to pass an interpolation curve fitting technique is used, the path to be followed by the pen being defined by with the constants being found by applying a set of constraints on the characteristic of the curve. The optimum command velocity for any segment is found by determining the curvature of the end points of the segment, selecting the larger k max  and choosing a velocity to plot the calculated maximum curvature. The distance necessary to get from zero to maximum velocity and vice versa is obtained from the equation length v 0 = 0 and v = v max . A dummy data point is created such that the length of curve from the dummy position to the required stop position is equal to the stop length. A general purpose computer generates the values a x a y  . . . c y , z s , v c  and they are fed either directly or by way of a magnetic tape stage to the control system (Figs. 3, 4). In operation a binary coded representation of V c  is fed to a digital differential analyser 3 together with a signal representing the actual plotter speed v to feed a signal v - v c  to detector 19 from which an acceleration or deceleration signal is derived. A digital differential analyser 1 receives positive or negative clock pulses, in accordance with whether acceleration or deceleration is required, and the difference signal v - v c  to feed a signal dv to a digital differential analyser 2. This sums the increments dv to generate the actual velocity signal v for comparison with the command velocity and also generates a signal dz = #dvdt. This is fed to a first series of digital differential analysers 24, 25, 26 which also receive the constants a x , b x , c x  to generate a signal The incremental signals dx are summed in a store 31 and compared with the actual x position to control the motor 37 positioning the x plotter. Similar circuitry also controls the y plotter. A counter 17 is preset to the value of the curve length z x  and is decremented by the signal delta z.

Title: Code identification systems
IPC: H04L19/00
Filed: 1947-08-07
Abstract: 645,264. Electric selective signalling systems. BENDIX AVIATION CORPORATION. Aug. 7, 1947, No. 21747. Convention date, Aug. 14, 1946. [Class 40 (i)] A receiver comprises a number of elements, e.g. drop-indicators R33 ... R55, any one of which can be selected by the joint action of uniselectors I, II which respond-respectively to two trains of short impulses separated by a long impulse. As shown, impulse-relay 25 repeats all impulses to release-relay 40 which operates and to relay 33 which repeats them somewhat delayed to change-over relay 36. The impulses to 36 are terminated by the impulse-relay directly and so are of shorter duration than the original impulses and 36 makes no response to the first train which thus operates the reverse drive stepping magnet 52 of uniselector I. The prolonged intertrain impulse also energizes the stepping magnet 52 which is cut-off before the end of the impulse to allow the final step by the operation of change-over relay 36. Stepping magnet 63 of uniselector II thus responds to the second half of the prolonged impulse and then to the impulses of the second train, 36, once energized, being held by the shortened train impulses. In response to the final relapse of the impulse-relay, slow-to-operate relay 45 pulls up, making its contact 47 before breaking its contact 49 and so making a momentary circuit for the drop-indicator selected jointly by the uniselectors. Shortly afterwards, the relapse of release-relay 40 completes homing circuits for the selectors and the circuit is restored to normal.

Title: Improvements relating to the separation of phenols from aqueous mixtures
IPC: C07C37/72
Filed: 1961-06-16
Abstract: A process for the separation of phenols from aqueous mixtures containing them, e.g. aqueous crude carbolic acid, comprises extracting with a phenol-dissolving extraction solvent containing organic compounds having a benzoyl group, e.g. acetophenone, or a derivative thereof, benzophenone, benzaldehyde, the esters of benzoic acid and similar high-boiling compounds with a benzoyl group. Preferably the extraction solvent also contains another phenol-dissolving extraction solvent such as benzene, and isopropyl ether.  When the extraction solvent contains benzophenone the extraction is carried out at a temperature above about 48 DEG C. when the stable modification is used and above about 26 DEG C. when the meta stable modification is used.  The extracted phenols may be recovered by distillation of the extraction solvent preferably under reduced pressure or by treating with an alkaline liquid then separating the aqueous solution of phenolates and recovering the phenols from the latter in known manner.
