Abstract: 997,420. Burning low grade fuel; hotwater boilers. Z. KOPPANY. Oct. 4, 1961, No. 35793/61. Headings F4A and F4B. Low grade fuel comprising a mixture of combustible and incombustible solid materials in which the major portion by weight is incombustible is burned in a frusto-conical combustion chamber 10 having an ignition space 20 separated from it by a fine mesh grid 21 extending diametrically across the chamber above a grate 22. Combustion air enters through access openings 20<SP>1</SP>, 23<SP>1</SP> and combustion products leave through a central perforated pipe 14 whose lower end 15 is closed and rests on rods 16. A water heating coil 17 is helically disposed about the outlet pipe 14. In a modification (not shown) the outlet pipe is replaced by a low pitch water heating coil, the gaps between the coils serving to replace the perforations in the pipe 14. The fuel may comprise coal slag of a granulation of 5 to 6 mm. to which heavy oil and sawdust may be added, or a mixture of high grade fuel with gravel. The fuel is moistened with water and charged into the combustion chamber through openings 13<SP>1</SP> and a wood fire is lit in the ignition space 20. This causes fuel lying immediately above the grid 21 to burn and water gas is formed, assisting in transferring combustion to the remainder of the combustion chamber. In due course the entire mass of fuel is in a state of flameless combustion. When the fuel is exhausted the combustion chamber is recharged and ignited as described above. Preferred dimensions are described.

Filed: 1957-11-18
Abstract: 826,319. Milling-machines. KEARNEY & TRECKER CORPORATION. Nov. 18, 1957 [Dec. 24, 1956]. No. 35802/57. Class 83 (3). A machine-tool comprises a control system for sequentially moving a cutter spindle quill 17 axially and clamping it in cutting position, the cutting position being adjustable. The work-table 14 of a milling- machine can be reciprocated at feed or rapid-traverse-rates beneath a cutter 18 on a spindle 15 mounted in the quill 17 movable axially on a vertically-adjustable head 13. An electric motor, through a variable-speed transmission, rotates a gear 33 which drives the spindle 15 through changegears 29. Rack-teeth 36 on the quill 17 are engaged by an adjusting-pinion 37 rotated by a worm-wheel 41 engaged by an axially-movable worm 42. The worm 42, Fig. 3, is mounted in a sleeve 43 having a cam-groove 53 engaged by a follower 54 so that when the sleeve 43 is rotated, by movement of a rack-plunger 69, it moves axially together with the worm 42. The worm 42 is rotated relatively to the sleeve 43, to thereby adjust the forward position of the cutter, by inserting a handcrank in a bore 65, the end of the crank serving to disengage a clutch 57. The quill 17 is clamped in its forward position by a split sleeve 75 contracted by a rod 80, Fig. 2, and nut 85, the degree of clamping being adjusted by a rotatable head 87. The nut 85 is rotated to clamp and unclamp the sleeve by a bell-crank 90 rocked by a fluid-pressure device 92, which is actuated when the plunger 69 is in its quill-forward position. A manually-operated valve is provided to permit the quill to be unclamped and adjusted while in its forward position; when, after adjustment, the quill is moved to its retracted position, the valve is automatically returned to its normal position. An electrical control system is provided to carry out a cycle of operations. Initially, the quill is clamped forwardly and table-traverse is commenced to effect a cut. At the end of the traverse, the table operates a switch 154 to unclamp and retract the quill. Movement of the plunger 69 actuates a switch 164 to return the table. At the end of the return-stroke, the table actuates a switch 155 to stop its movement, and to advance and clamp the quill. The plunger 69 then actuates a second switch 163 and the cycle is complete. In a modification, the retracted position of the quill is also adjustable.

Title: Fluorine and sulphur recovery from waste gases
Inventor: HINKLE JOHN HOMER
IPC: C01B7/19
Filed: 1962-09-21
Abstract: A process for recovering fluorine and sulphur values from waste gases obtained from the acidulation and/or calcination of phosphate minerals comprises scrubbing the gases with water to absorb fluorine and/or fluorine compounds, converting the absorbed fluorine compounds into a form which is insoluble in water, and flowing the scrubbed gases in a non-recirculated continuous stream through a unit which converts all sulphur compounds to sulphur trioxide and absorbing the sulphur trioxide in sulphuric acid to produce sulphuric acid. The preferred method of recovering fluorine values is to add silica to the water containing dissolved fluorine compounds in order to convert any HF to SiF4 and/or H2SiF6, and then add soda ash to precipitate Na2SiF6 which may be separated by filtration.  The scrubbing water may be recycled to scrub the waste gases and to produce a 6-20% F. concentration therein. The sulphur recovery portion of the plant is of the type conventionally used for manufacture of sulphuric acid from sulphur, using catalytic oxidation, the catalyst being, for example, finely divided platinum on an aluminum carrier.

The knife 4 is carried by pulleys 5 on a frame 6, the frame being movable vertically on a support 9. The support is mounted on a horizontally movable carriage 13. Extending from the frame 6 is an arm 6b carrying a photo-electric scanner head 29, the latter being mounted eccentrically on a shaft 30 of a stopping motor 31. The head 29 is moved in steps of the order of 200 per second anti-clockwise, as shown in Fig. 4, until the template outline is sensed. It then moves clockwise and so on following the shape. Motor movements are transmitted to the knife to twist it into parallelism with a tangent to the template surface at the point of scanning, Figs. 4, 6. This is achieved by passing the knife through slots in spaced discs 20, 21 which are rotated by a belt 32 transmitting motor rotation to a system of connected racks 33, 22, 23, 25. The discs are initially positioned to twist the knife 180 degrees out of the straight so that the full 360 degrees adjustment is obtained by 180 degrees rotation in either direction of the discs. The x, y movements of the knife are derived from the changing position of the tangent at the template, this being transmitted to potentiometers 39, 40 controlling the drive motors 11, 16 of the frame 6 and carriage 13 respectively. One or more templates 26 may be mounted on a panel 27 to cut vertically successive shapes from a block 3 held stationary on a table 2 or on an infeed conveyer (41), Fig. 3 (not shown). If only one template is used, the panel 27 may be arranged to move vertically to the desired positions. The knife may reciprocate instead of travelling continuously.

Title: Method and apparatus for controlling the sliver-thickness variation in a carding machine
IPC: D01G15/36
Filed: 1976-09-02
Abstract: 1505209 Controlling sliver thickness from a carding machine TOYODA JIDOSHOKKI SEISAKUSHO KK and TOYOTA CHUO KENKYUSHO KK 2 Sept 1976 [6 Sept 1975] 36316/76 Headings D1F and DIN [Also in Divisions F2 and G3] In a carding machine the sliver thickness variation is controlled by detecting the sliver thickness and representing it by an electric signal, this being compared with a constant signal to produce a difference signal, the latter being intermittently converted to a control signal by means of which the feed to the carding machine is intermittently adjusted to reduce the difference signal towards zero the intermittent time intervals each being shorter than the time of a long term variation of sliver thickness. High frequency variations are filtered out of the electric signal so that only long term variations are corrected. In a first embodiment of the invention a vibrating waveform such as a triangular, saw tooth or sine wave is added to the difference signal and where the resultant waveform goes beyond upper and lower limits a pulse is produced whose length is representative of the amount by which the limits are exceeded. The pulses which occur intermittently are used as the control signal. An alternative embodiment has a timing signal which initiates intermittently a time constant function which ceases when it attains the value of the difference signal. The time over which this occurs produces a pulse which again is used as the control signal. The third embodiment has a frequency generator operated by the difference signal, the generated frequency producing a pulse train which provides the control signal. The sliver thickness is sensed by the rollers 12a, 12b, Fig. 2, the signal being magnified by a lever train and applied to a potentiometer 19 which provides the electric signal. The lever 14 has a resilient part which together with a damper 20 eliminates the high frequency component of the signal. The control signal operates a control motor 22, Fig. 1, which alters a variable gear drive 23 with an input shaft 23a from the carding machine and an output shaft 23b to a feed roller 11. The variable speed drive, Fig. 5(a) is an epicyclic friction gear, the variation deriving from the position of an annulus 39 on conical planet wheels 37. The gears are maintained in friction engagement by a thrust cam 35 on the input side. The Specification refers to the use of measuring rollers cooperating with electrodes between which the electrostatic capacity is measured as an alternative to the levers and potentiometer. Other alternatives referred to are a variable speed drive motor for the feed roller or a variable dimension chute for feeding the carding machine.
