Title: Beam-backed cold rolling mills
IPC: B21B31/26
Filed: 1963-01-23
Abstract: 988,196. Rolling. T. SENDZIMIR. Jan. 23, 1963, No. 2828/63. Heading B3M. A sendzimir type mill has its housing formed in two halves which are hinged at one end, and urged together with a force which exceeds the rolling force tending to urge the halves apart. Each half houses a working roll supported by two series of backing rolls and a number of casters. An hydraulic cylinder 7 is attached to one half 2 and stresses tie rods 11 and 12 which are attached to the upper half 1 and to a platen 9. Adjustable ribbed blocks 4a and 4b are bolted on to correspondingly ribbed portions of the halves 1 and 2, and are recessed to house a hinge pin 4e. An hydraulic cylinder 42 moves a lever 40 to rotate eccentrics 38 and 39 and thus adjust the roll pass. The eccentrics may be geared together or actuated by separate cylinders. Fig. 5 shows how the working rolls 46 are supported by first backing rolls 47, intermediate backing rolls 48, and casters 49. The casters are spaced along shafts 50 by saddles 51 which bear against the mill housing halves. Saddles 53 across the width of the rolls are each adjustable by a bolt 52 so that the crown of the working rolls can be adjusted. The central intermediate backing roll is driven in each half of the mill. The work roll and first backing rolls of each half are movable axially in carriages 65, 67, or 66, 68, cross pieces 71, 69, and 72, 70, joining the ends of these carriages. Screws 75 and 76 are used for this axial adjustment. The carriages are provided with perforations for forming jets for a lubricant and coolant. Rolling materials of different widths is facilitated by providing the ends of the rolls of one or both of the intermediate series with slight taper reliefs, adjustment of the rolls being by relative longitudinal movement.

A radio direction-finding aerial comprises a bar 10 of magnetic material, associated pick-up and coupling coils, and a co-operating angularly graduated scale from which the bearing of a beacon can be read. The aerial is particularly intended for use on small boats and may be coupled to a normal communications receiver for direction-finding by the null method. It may be mounted on a compass bowl 33 as shown in Fig. 1, the scale then being the compass scale. The bar is preferably about 10 times as long as its diameter and is provided with a substantially central pick-up coil 11 tuned by a variable condenser 12 adjusted by knob 32. Condenser and coil are mounted inside a screening can 13 having a slot 16 to prevent the can forming a short circuited turn. A coupling coil 14 wound round the bar 10 outside the screen is critically coupled to coil 11 and connected to a coaxial feeder leading to the receiver. On the other side of the screen a further coil 17 is wound round the bar and may be coupled through a resistor to an open sense aerial. The other end of coil 17 is connected to brass ring 20 capacitively coupled to case 13 which is in turn capacitively coupled on its opposite side to brass ring 22 connected to the outer (earthy) side of the coaxial cable feeder. Each of the rings 20 and 22 is provided with a radial gap. The projecting ends of the bar 10 are encased in protective insulating tubes 25 screwed into insulating members 26 which contain the coils 14 and 17 respectively and are attached to central insulating member 27. Member 27 is mounted on verge ring 29 by legs 28 and the ring 29 may be provided with a recess engaging the sighting means of the compass so that radio bearings can be taken quickly and accurately. Where the aerial is not to be mounted on a compass but on a flat base for use on a chart table the aerial is fixed to a plate 36 rotatably mounted on the base and carrying a pointer. A co-operating scale 35 is made independently rotatable so that the ship's heading may be set in against index 39 and the base is attached to the table with the part 38 aft so that a direct reading of bearing can be obtained.

Title: Improved device for scribing ellipses
IPC: B43L11/04
Filed: 1946-02-06
Abstract: 608,944. Ellipsographs. ROBINS, T. H. Feb. 6, 1946, No. 3792/45. [Class 97 (iii)] In a device of the kind wherein two legs are guided along two lines at right angles and the ellipse is traced out by a marking leg in line with the others, one end leg is used for scribing, and one of the legs is so constructed or mounted that it can move axially in a direction to allow the scribing point to be brought into contact with the drawing surface. The guides are provided in or on the upper surface of a guideplate which can be pivoted on the drawing surface at or near the intersection of the guides. The instrument shown in Fig. 1 comprises a pair of compasses, one arm 15 of which is pivoted at 20 to a bracket 21 having a guiding leg X and an arm 23 sliding in a groove in the bracket, and adjustably fixed by the screw 24, and having a second guiding leg Y. The pencil Z is moved into contact with the paper by movement of the arm 15 about the pivot 20. Instruments are also described where the compass arms are adjusted by a threaded pin having threads of opposite hand, or where a pair of adjustable bows is pivoted to the arm 15 in place of the bracket 21. Alternatively, a beam compass is used having three legs, the position of at least two of which is adjustable along the beam, and the effectivelength of one of the legs is self-adjusting by a spring-loaded telescopic device to enable the scribing point to move into contact with the paper. The guide member of Fig. 5 has a pin 79 by which it may be pivoted to the drawing-sheet so that the ellipse may be completed at the ends by turning the guide member about the pin. The pointed ends 80, 82 are for location with the major and minor axes respectively. The guide member of Fig. 7 has a carriage 89 sliding in an undercut slot 90, the leg 7 being placed in the opening 88 in the carriage. The slot 87 for the leg X is continued beyond the slot 90 a distance equal to the amount by which the opening 88 is offset. By this means the scribing instrument can describe half the ellipse, the guide member being held fixed by the pin 86. For scribing the other half, the guide member is rotated through 180 degrees about a pin inserted through the hole 85. In all cases, one guide groove is appreciably wider than the other, and each has a cross-section semicircular at the bottom and widening towards the top. The legs differ in diameter so that they cannot be wrongly placed in the grooves.

Filed: 1966-01-27
Abstract: Cyclopolysiloxanes of the formula <FORM:1093872/C3/1> where R is a monovalent aryl radical and a is 1 or 2, may be obtained by reacting a 1,1-dichlorodibenzosilole with an organopolysiloxane diol of the formula <FORM:1093872/C3/2> in the presence of a solvent and an acid acceptor. Specified acid acceptors are tertiary amines, e.g. pyridine, picoline, 1,4-diazobicyclo (2,2,2) octane and dialkylanilines.  Specified aryl groups represented by R are phenyl, o-tolyl, m-tolyl, p-tolyl, o-trifluoromethylphenyl, m-trifluoromethyl phenyl, p-trifluoromethyl phenyl, cyanophenyl, benzoyl phenyl, p - phenoxyphenyl, xylyl, ethylphenyl, naphthyl and biphenylyl. Specified solvents are hydrocarbons and polar solvents such as ethers and fletones. The 1,1-dichloro benzosilole starting material is obtained by reacting 2,21-dibromodiphenyl with butyl lithium and reacting the 2,21-dilithiodiphenyl thus formed with silicon tetrachloride to form 1,1-dichlorobenzosilole and 5,5-spirobi (dibenzosilole) as a by-product.  The products may be blended, for example, with 0.1 to 10% by weight of a chlorophenyl methyl polysiloxane fluid to yield a high-temperature resistant grease formulation.

Title: Process controller
IPC: H03F99/00
Filed: 1965-01-28
Abstract: 1,045,051. Automatic control. GENERAL ELECTRIC CO. Jan. 28, 1965 [Feb. 24, 1964], No.3833/65. Heading G3R. [Also in Division G4] In a process control system, a current corresponding to error in the magnitude of a measured variable of the process is applied through a differentiator and an electrochemical integrator to maintain the variable at a desired value. Current from a transducer 11, dependent on the magnitude of a process variable, is compared with current, corresponding to a desired value of the variable set at a source 12, and any difference is differentiated by a circuit including a capacitor 25. With switches 30 in the upper position the output of the differentiator is applied between input and common electrodes 19, 16 of an integrating, electrochemical, cell 14 having iodine-iodiode electrolyte, an output electrode 17, and a guard electrode 18. The cell electrodes are of platinum. Zener diode limiters 23, 24, 39 and a resistor 31 are provided to prevent overloading of the cell. Output electrode 17 is biased with current to permit larger input currents to be used and this current is maintained despite temperature variations by a temperature variable resistor 33. The voltage bias of the output and guard electrodes are made equal to prevent gassing. The current from integrator output electrode 17 is amplified by transistors 40, 42, 49 to provide two output current supplies 43, 45 varying in opposite senses, the appropriate one of which is used to correct deviations of the variable automatically. The amplifier is provided with temperature compensating negative feedback through resistors 47, 48. With switches 30 in the central position, automatic control is disabled and manual control may be effected by operating a switch 50 in either direction from an off position to apply current in a corresponding sense through cell 14. Earthing by switch 30b ensures smooth reversion to automatic control. A circuit 60 including biased diodes is effective to maintain the output of amplifier 13 between limits by controlling the input to cell 14 if the limits are exceeded. By moving switches 30 to the lower position, manual control may be effected by varying the input to cell 14 by means of a potentiometer 80 in circuit 60, this arrangement having the advantage that, due to permanent feedback from potentiometer 80 to the cell, drift does not occur when manual control is used for long periods. Smooth changeover with this form of manual control is effected by first setting potentiometer 80 with the aid of a meter 81. Zener diodes 41, 66 provide stabilized voltages.
