Title: Improved method of making sulphur from sulphur dioxide
IPC: C01B17/04
Filed: 1920-06-03
Abstract: 144,306. American Smelting & Refining Co., (Assignee of Howard, G. C.). Sept. 9, 1918, [Convention date]. Sulphur.-In the process for the recovery of sulphur from sulphur dioxide by mixing with air and passing the mixture over incandescent coke, the reacting gases are dehydrated prior to mixing. The sulphurdioxide content of metallurgical gases is isolated therefrom, dehydrated, liquefied and stored in the tank A, whence it can be discharged through the expansion coils C into the main G, where it is mixed with dehydrated air forced in by the pump E. The ratio of sulphur dioxide to air is regulated by means of the valves B, D and F. The air may be dried either by scrubbing with concentrated sulphuric acid or by passage through one of the double pipes of the expansion coil. The dry gaseous mixture then passes through the pre-heating tubes H into the furnace K, where it comes into contact with coke maintained at incandescence by adjusting the amount of air in the mixture. The resulting gases containing sulphur escape through the flue M to the preheater N, and thence to the chamber O and filter Q, where the sulphur settles out, the remaining gases passing to atmosphere.

Abstract: 612,223. Suction cleaners. HOOVER, Ltd. May 20, 1946, Nos. 15190 and 15191. Convention dates, June 13, 1945, and June 23, 1945. [Classes 8 (i) and 8 (ii)] In a suction cleaner comprising a suction creating means, e.g. a fan 24, Fig. 1, at one end and a filter 41 at the other end bearing a removable cap 6, dust is removed from the filter 41 by removing the cap 6, mounting the cleaner with its open end engaging a supporting surface and shaking the filter by means including an operating member located outside the casing, e.g. a pedal 81 (not shown). The filter shaking mechanism comprises a spring-pressed parallel linkage 46, 47 normally holding the closed end of the filter bag taut by brackets 48. A tension rod 67 connected at one end to one of the links 47 and at its other end to a slide 64, Fig. 3, is mounted on a guideplate 61 formed on a plate 57 fixed to the casing interior. On pivotal movement by the pedal 81 of an operating lever 71 a spring-loaded pawl 76 mounted thereon firstly engages rollers 66 on the slide 64 to move it longitudinally and so move the links 46, 47 against a spring 56, and secondly moves out of engagement with the rollers 66 so that the slide 64, rod 67 and links 46, 47 are suddenly released to tauten the bag 41 with a snap-action. In a modification the upper ends of the link 46 are rigid with a spring-loaded shaft rocked so as to be released with a snap-action on the return of a spring- loaded square-sectionedsliding rod. This return is made after the disengagement of a spring-pressed pawl from a roller mounted on an arm rigid with the shaft. The cleaner also includes a secondary filter 37, and an air outlet 3 to which a pressure dusting tool may be connected.

Title: Digital accumulator and coder
IPC: H03M3/04
Filed: 1975-04-14
Abstract: 1494281 Delta modulation WESTERN ELECTRIC CO Inc 14 April 1975 [18 April 1974] 15320/75 Heading H3H [Also in Division G4] In a delta modulation encoder or decoder, the reconstructed analogue signal 28 or 31 is obtained from a ladder network 25 or 30 whose rung resistors are connected to parallel outputs of a reversible shift register 19 or 29, the contents of which are stepped one way or the other by each clock pulse 20 according as the delta bit stream 18 contains or does not contain a pulse at the time of the clock pulse, a binary one or zero being inserted into the vacated end stage of the register. Thus at any time the shift register contains a number of consecutive binary zeros at its most significant end and consecutive binary ones at its least significant end. In the ladder, resistors 27 are all equal to R, resistors 26 to 2R, providing logarithmic companding. In Fig. 2B, each rung resistor comprises two resistors 26<SP>1</SP>, 26<SP>11</SP> each equal to 4R. In the encoder of Figs. 2A, 2B, a balanced analogue input signal 50, 51 is linearly amplified and fed to a differential amplifier 11, also receiving the fed-back reconstructed analogue signal 28. The resulting difference signal is integrated at 12, diodes 93, 99 clipping excessive voltage. A threshold circuit 13 provides true and complement delta bit streams 21, the second flip-flop 107 eliminating any unwanted pulse-width modulation which can occur in the output of flip-flop 106 at low signal levels on line 103. The signals 21 control the direction of shifting in the register 19. For negative signals, a zero cross detector circuit 116 responsive to underflow in register 19 (when its least significant stage contains zero and the true output of flipflop 107 is one-i.e. the encoder output 18 is zero) selects the complement of the output of register 19, applies a pedestal voltage shift to the least significant end of the ladder, and reverses the polarity of the connection between flip-flops 106 and 107. Thus an error in the form of a spurious one or zero in the delta modulation bit stream is automatically "forgotten" when the reconstructed signal next crosses zero; theory given. The zero cross detector also applies feedback to the differential amplifier 11 via low pass filters 138, 140, 141 to force a change of sign in its output if the amplitude of the reconstructed signal remains below the least significant quantum step size for a given time. Overflow of register 19 is detected on line 132 and used to force a zero output, whereby a too high analogue input causes oscillation between the two highest states of the reconstructed signal. The encoder output may be taken from the parallel outputs of the shift register 19.

Title: Twin roll mounting for cross roll straightening machines
IPC: B21D3/04
Filed: 1959-05-06
Abstract: 868,878. Skew-rolling. SUTTON ENGINEERING CO. May 6, 1959 [May 27, 1958], No. 15507/59. Class 83 (4). A twin cross roll mounting, for use in a skew roll straightening machine for straightening lengths of round stock, comprises a cradle frame, two roll assemblies supported by the cradle frame, each roll assembly including a separate cross roll adapted to contact the stock being straightened, each roll assembly having a thrust axis passing through the centre of the roll and intersecting the longitudinal axis of the stock and the roll axis substantially at right angles and also having a thrust plane defined by its thrust axis and the longitudinal axis of the stock, the dihedral angle between the thrust planes being variable inversely to the outside diameter of the stock when straightening stock of different sizes. Two large lower skew rolls 80 are each opposed by a pair of upper skew rolls 18, and a centre pair of upper skew rolls 18 serve to deflect bar or tube stock passing through the machine. Each roll 18 of a pair is carried by a bracket 17 pivotally mounted on a bearing block 16 by a pin 23. The blocks 16, of a pair of rolls, bear on part cylindrical shoes 8, 9 secured to a common cradle 2, movably vertically by screw-down means 3. Arms 41 extending from the blocks 16 are pivotally secured to internally threaded blocks 45 on oppositely threaded portions 46a, 46b of a screw 46 turned by a hand wheel 49. To adjust the rolls 18 of a pair simultaneously about the axes of the bearing surfaces of the shoes 8, 9. The degree of skew of the rolls 18 is automatically adjusted, as the blocks 16 are adjusted on the shoes 8, 9 by the action of links 53, 54 pivoted to the brackets 17 and blocks 16, respectively, and to a link 51 pivoted to the cradle 2. In a modification, Fig. 10, the adjustments are effected by a screw 67, skewed in a horizontal plane, engaging threaded blocks 66 to which are pivoted U-shaped members 61 from each of which projects a pin 63 (Fig. 9, not shown) loose in a hole. in a socket member 62 secured to the bracket 17. The skewness of the screw 67 may be adjusted. The bearing surfaces of the blocks 16 and shoes 8, 9 can alternatively be spherical. Lower pairs of rolls may be mounted in the same manner as the rolls 18, but with the axes of the bearing surfaces of the shoes 8, 9 to one side of, instead of in the thrust planes of the rolls. The distance between the roll centres slightly increases and the angle between the lines through these centres and the longitudinal axis of the stock decreases as the rolls are adjusted to engage larger diameter stock. The pivot pins 23 may be eccentric to the centres of the rolls. The roll mountings may be at the sides of the stock instead of above and below.

Abstract: 938,651. Controlling aircraft. BENDIX CORPORATION. April 25, 1962 [May 3, 1961], No. 15672/62. Class 4. An arrangement for controlling an aircraft comprises a stick assembly having means rotatable about a first geometric axis for controlling the craft about a first control axis thereof (e.g. the roll axis) and having means rotatable about a second geometric axis generally normal to the first for controlling the craft about a second control axis thereof (e.g. the pitch axis), and a manual control member e.g. wheel, mounted on said assembly for limited rotational displacement with respect thereto about said first geometric axis and for limited axial displacement with respect thereto parallel to said first geometric axis, resilient means urging said manual control member towards a neutral position relatively to said stick assembly both in rotational and in axial displacements, and signal generator means actuated on displacement of said manual control member from its said neutral position to generate signals corresponding to the sense and amount of rotational and axial displacements of the control member from neutral with respect to said assembly. The apparatus forms part of a control system in aircraft such as is described and claimed in Specification 801,941 in which a control column 8 and wheel 7 are mounted respectively for fore-and-aft and rotational movement to provide control signals to operate directly or in association with an automatic pilot the elevators and ailerons. The wheel 7 is mounted on a shaft 31 carried by bearings 39A, 39B in column 8, the shaft being splined at 51 to carry the inner race 50 of a caged bearing 55, 52, which permits axial and rotational movement of the hub 20 of wheel 7. The hub is connected to shaft 31 by a diaphragm spring 30, as by screws 32 and lock nut 38 which holds the wheel in an undeflected position relative to the shaft. Pitch and roll sensors 18 and 19 are respectively secured to spokes 21 and 22 of the wheel and connected by linkages 75 and 93 to a flange plate 62 fast with the inner race 50. A stop bolt 110 screwed into hub 20 co-operates with a slot 111 in plate 62 to limit rotational movement of the wheel and the shank portion 114 is of such a length as to limit the axial displacement of the wheel. Within these limits signals generated at 18 and 19 operate the servo controls and beyond the limits, rocking of column 8 or rotation of wheel 7, through a chain drive 35, and linkages not shown, operate the servos directly.

Title: Improvements in Colour Television
Inventor: RAINGER PETER
IPC: H04N9/07
Filed: 1966-04-07
Abstract: 1,167,561. Colour television. BRITISH BROADCASTING CORP. 7 April, 1967 [7 April, 1966], No. 15689/66. Heading H4F. A plurality of colour separation images are formed side-by-side on the face of a single camera tube which is scanned in a manner such that each raster line traverses all the images in turn, the resulting signals being delayed relatively to one another in such manner that signals derived from the same region of different colour separation images occur simultaneously. The invention is described only as applied to apparatus using red, green and blue separation images, but reference is made to apparatus which uses a fourth, luminance, image. An anamorphotic optic system may be used so that the images are of different sizes with the object of achieving optimum signal-to-noise conditions and a wider bandwidth for a luminance signal where a fourth image is used. The signals provided directly from the camera are line sequential and are converted to simultaneous form. This may be done by signal repetition using delays of one line and two lines in each colour channel. The line rate of the camera raster is one-third that of the final simultaneous signals and may give inadequate vertical resolution. Sich a defect may be avoided by interpolation techniques (see Specification 1,025,512) or by increasing the camera scanning speed and using a line standards converter (see Specification 928,730). In another arrangement, Fig. 1, the camera is subjected to high-frequency spot wobble in a direction transverse the lines over a distance of two lines by deflection coil 20 and the signals corresponding to the two lines are directed into separate delay channels 12, 13 and 14, 15, 16 by synchronous switch 11. Each element in the delay channels produces a delay of one line, i.e. the time of scanning one colour separation image. Simultaneous signals are then formed by combining direct and delayed signals in an interpolation system 17 which may be similar to that shown in Fig. 8 of Specification 1,025,512. The interpolation procedure is explained with reference to Figs. 2-4 (not shown). The final simultaneous R, G and B signals are applied to a coder 18 to produce an output at 19, e.g. of N.T.S.C. form.
