Title: Improvements in or relating to Deflection Systems for Corpuscular Beam Apparatus
IPC: H01J37/153
Filed: 1967-03-14
Abstract: 1,157,750. Corpuscular beam irradiation apparatus. SIEMENS A.G. 14 March, 1967 [15 March, 1966], No. 11854/67. Heading H1D. In corpuscular beam apparatus for irradiation of an object a corpuscular beam deflection system, employing either electric or magnetic fields to effect the deflection, includes a stigmator whose excitation is made dependent on the excitation of the deflecting system in order to correct for any deflection astigmatism, the magnitude and direction of which depends on the deflecting field, produced by the deflecting system, wherein the stigmator comprises one or more pairs of coils, connected to produce mutually opposing magnetic fields, and whose common axis is perpendicular to the beam direction, and the stigmator coils are provided as additional windings on an electromagnetic stigmator serving for correction of axial astigmatism. Two perpendicular pairs of deflecting coils are necessary if there are two perpendicular deflecting fields. The stigmator may be arranged before the deflecting system with each pair of coils perpendicular to the deflecting field. Although the astigmatism (A, Fig. 1), produced by the deflecting field is related in a roughly square law fashion (K1) to the deflecting system current (I) and a corresponding stigmator current relationship (K2) is ideal, the astigmatism may be reduced to an acceptable level (K4) if the stigmator excitation is directly proportional to that of the deflecting field (K3). Variable resistances in series with the stigmator coils may be used to permit matching of a stigmator to an associated deflecting system.

The work spindle 17 carrying a faceplate 34 on which a ring gauge 35 is mounted in bearings 20, 21. and is urged to the right in Fig. 2 by a spring 22 located between a washer 43 and a washer 41 engaging a sleeve 39 pinned to the spindle at 40. The spindle carries a cam 23 having a surface 24 generated by a radial line 24a which rotates round the spindle axis to position 24b while gradually increasing its inclination to a transverse plane. The cam is engaged by a roller 25 which is radially adjustable in a bracket 30 which may be graduated in pitch sizes or threads per inch. Thus as the spindle is rotated by a hand-wheel 18 the spindle is moved axially by an amount depending on the setting of the roller 25. The starting position is determined by the engagement of the pin 40 with a fixed projection 44 and the end of the operative movement by an adjustable member 45 on the hand wheel engaging projection 44. In a modification the surface of the cam member may be grooved, each groove corresponding to a definite pitch, or the cam may be formed with steps. Alternatively, the cam may be double-sided, opposite sides being used for threads of opposite hands or if the required rotation of the work spindle is less than 180 degrees the cam member may have two portions on the same face adapted for threads of opposite hand. The wheel engages the work as shown in Fig. 4. In some cases the spindle may be driven by power.

Title: A process of converting hydrocarbon materials containing distillable and non-distillable hydrocarbon constituents into distillate oils and coke
IPC: C10B55/10
Filed: 1952-05-13
Abstract: <PICT:0720612/III/1> Hydrocarbon materials containing distillable and non-distillable constituents are distilled to give distillate oils and non-distillable residue, the residue is thermally cracked in liquid phase in the presence of added subdivided solids to coke and distillable oils, the coke and cracked oil are separated and the oil returned to the distillation zone.  As described, crude oil mixed with cracked oil from line 3 is preheated at 5 and distilled in column 9.  Reduced crude bottoms are taken, preferably via heater 21, to vacuum flash tower 23, a gas oil being recovered overhead and a pitch boiling above 1100 DEG F. being taken via heater 37 to heat-soaker 41.  Fresh seed coke of particle size 5-250 microns may be added from lock-hopper 33 but is preferably added as a slurry from line 35.  The pitch is cracked at 780-820 DEG F. and about 2000 p.s.i. in coil 37 and soaker 41 where it is agitated by propeller 42. Total cracking time may be 1-3 hours.  From soaker 41 cracked products are taken, after releasing pressure, to flash drum 45 from which vapours are fed back to column 9 and a slurry of heavy oil and coke taken to a separator which may be a rotary filter 50.  The cracked products in line 48 may be further cooled to 200-450 DEG F. by cooled coke-free oil from line 51.  Liquid filtrate and vapours are passed from filter 50 by line 52 into tank 54 from which liquid is taken to column 9 by line 3 and vapours recovered by line 61 or passed to column 9 by line 63.  Wet coke from filter 50 is dried at 67, vapours passing to tank 54.  Dry coke is withdrawn at 71, part being taken to line 35 to be slurried with product-naphtha from line 13 and fed to the cracking stage.  Alternatively wet coke from filter 50 may be passed by line 77 to line 35.  The seed coke may be disintegrated at 79.  To start up the process other subdivided solids such as clay or ashes may be used.  In a modification the vacuum tower 23 is omitted and the atmospheric residuum in line 19 passed direct to line 31.  Products from tower 9 may be subjected to standard operations such as stabilization, absorption, alkylation, hydroforming, and catalytic cracking to obtain the required products. In an example a mixed crude is fractionated, the bottoms are blended with 14 per cent. heavy naphtha containing 53 pounds of 100-200 mesh coke per barrel, and heated to 800 DEG F. under a pressure of 2100 p.s.i. for 150 minutes. After filtering the coke product is heated to 1000 DEG F. in a retort, a yield of 31 pounds of coke per barrel of feed to the cracking stage being obtained.

Title: Automatic thickness regulation in rolling machines
IPC: B21B37/48
Filed: 1957-04-15
Abstract: 806,370. Rolling plastic materials. BRUCKER, H. April 15, 1957 [April 23, 1956], No. 12260/57. Class 87(2). [Also in Groups XXII and XXXV] In apparatus for regulating the thickness of rolled thermoplastic materials, &c. by automatically varying the tension before or after the roll gap according to measured thickness variations, the roll pass is also adjusted automatically when the tension varies outside preset limits. Strip 1, Fig. 1, supplied under tension from a reel 2 braked by a motor 4 is rolled between adjustable rolls 7, 8 and wound under tension onto a reel 12 driven by a motor 14. The strip passes over tension rollers 16, 17, 18 on each side of the roll pass, the control movable roller 18 being supported through a piston rod 19 by a spring 25 and a piston 20 in a cylinder 21 in which the pressure is set to give a predetermined tension of the strip. The tension is normally maintained constant by the engagement of a contact arm 22 on the piston rod 19 with contacts 23, 24 controlling the torque of the motors 4, 14 through servo-motor systems. A thickness measuring device 29 with sensing rollers 30, 31 is placed behind the rolls 7, 8 and varies the tension in the strip by opening inlet or outlet valves 26 or 27 which raise or lower the pressure in the cylinder 21 so that the roller 18 and piston 20 is moved causing the contacts 23 or 24 to be engaged with a resultant change in the torque of the motor 14 and strip tension. The pressure in the cylinder 21 is indicated by a monometer 32 having electrical contacts 33, 34 set at the limiting values of pressure as determined by the required limits of strip tension. As soon as these limits are exceeded the contacts cause the valves 26 or 27 to close preventing further changes in tension and operate a servo-motor which reduces or increases the roll pass by raising or lowering the roll 7.
