Title: Chlord control system for electronic organ
IPC: G10H1/38
Filed: 1974-05-03
Abstract: 1448159 Electrophonic musical instrument WARWICK ELECTRONICS Inc 3 May 1974 [4 May 1973] 19655/74 Heading G5J In an electronic organ, keys of one keyboard are arranged to produce either a single note or a chord and depression of a key on another keyboard alters the chord produced. As shown, when a key, C for example, on the lower manual is depressed it operates a single pole switch 25 and this connects the outputs of two octavely related tone generators 29, 30 to the output 24. Closure of switch 35 generates a major chord whose root is the key depressed. Ten volts from the Zener diode 56 is applied via line 40 to a diode 43 which conducts to pass the corresponding tone G to the output. Other diodes. are actuated 69 but their corresponding output switch, 27, grounds the resultant output. The same ten volts turns transistor 44 ON and thus gives a positive signal to diode 31 which passes the remaining note E of the major chord to the output 24. The chord modifier is turned on by closure of switch 36. The chord is modified to a minor chord when any natural pedal 37 is depressed, ten volts being passed to line 47 thus turning transistor 44 off and 48 ON and effectively grounding line 51 inhibiting E which no longer passes to the output. The same ten volts forward biases diode 59 and D sharp appears in the output. The major chord is modified to a seventh when any sharp pedal 38 is depressed, ten volts being passed to turn on diode 63 adding A sharp to the output. The transistor 44 remains ON and all the notes of the major chord continue to sound. The major chord is modified to a minor seventh when any natural and any sharp pedal are simultaneously depressed. Ten volts is passed so that A sharp continues to sound, but  transistor 44 is turned off eliminating E from the output while D sharp sounds as in the minor chord.

Pipes 5 terminating in suction nozzles which are held up to the bolls are connected to nipples 4 situated on; the top of a casing 3 mounted on the frame of a motor vehicle. The stream of air carrying the cotton is directed against an inclined baffle 6 arranged across the top of the casing and then passes between baffles 8, 9 to a grid 10, the position of which may be altered by adjusting lugs 10<b>. The cotton is caught by this grid and moves down it to a pick-up roller 12 which carries it past a baffle 18 to a rotating brush 16 that discharges it on to a second grid 17. The air passing through the grids 10, 17 carries with it pieces of leaves and other foreign matter which are directed by baffles 11, 13 into a well 14 whence they may be removed through a discharge opening 15, the air being drawn through a conduit 2 by a pump 1. The cotton is lifted by a second pick-up roller 19 from the grid 17 and carried round to a second discharging brush 21, the roller 19 fitting closely to the casing to prevent air being drawn backwards from the discharging chamber 20. The brush 21 throws the cotton into pockets in a rotary drum 23<a> that fits closely within curtain walls 24 and transfers the cotton into a chamber 25, whence it is carried through a discharge port by a current of air fed through a pipe 27. To permit the vehicle to be moved at a slow pace through the fields the pump, the pick-up rolls, and the brushes are arranged to be driven from the motor independently of the driving-wheels.

IPC: C10K1/10
Filed: 1949-08-04
Abstract: 694,773. Purifying coal gas. SIMON-CARVES, Ltd. (Otto & Co., Ges., C.). July 25, 1950 [Aug. 4, 1949], No. 20298/49. Class 55(ii) In a process for removing H 2 S and NH 3  from coal gas, the gas is first washed in the bottom section of a scrubber 4 with a mixture of liquor from the middle section of the scrubber. and a concentrated NH 3  solution practically free of CO 2  and H 2 S and then in the middle section of the scrubber with a liquor consisting of liquor from the bottom section of the scrubber which has been treated to remove H 2 S and CO 2  and liquor from a later washing step in which the bulk of the ammonia in the gas is removed. The gas is further washed in the top section of the scrubber 4 with cooled recycled liquor from the hydraulic main 2 and finally in a second scrubber 5 with a mixture of fresh water and cooled liquor from the hydraulic main 2, the resulting liquor from this washing being fed to the middle section of the scrubber 4 via the line 30. Liquor from the bottom section of the scrubber 4 passes, partly through a heat exchanger 31, to a vessel 36 in which it is treated with steam to remove H 2 S and CO 2 . A cooler 39 is arranged in the upper part of the vessel 36 and the gases leaving the vessel consisting mainly of CO 2  and H 2 S are scrubbed with water supplied by the pipe 38. The scrubbed gases pass by line 37 to an ammonia saturator 13 and then to a sulphur recovery plant 14 which recovers the sulphur as sulphuric acid. Some of the treated liquor from the vessel 36 is returned through heat exchanger 31, cooler 32 and line 33 to the scrubber 4, the remainder passing to a still 41. Steam is supplied to the still 41 in a quantity sufficient to strip about 85 per cent of the NH 3  in the liquor and the resulting vapours are partially condensed in a cooler 44 to obtain a concentrated NH, solution practically free of H 2 S and CO, which is fed back to the scrubber 4 by a line 34. The uncondensed vapours from the cooler 44 are treated in the saturator 13. Liquor from the still 41 flows to a second still 43 where it is treated with a further and larger quantity of steam to remove the remaining NH 3 , the NH 3  removed and excess steam passing to the vessel 36 through line 47 to supply the steam required to remove the H 2 S and CO 2  from the liquor from the scrubber 4.

Abstract: 1,271,687. Wagon tipplers. STKACHAN & HENSHAW Ltd. 21 July, 1970 [22 April, 1969], No.20487/69. Heading B8E. A tippler for rotating a rail wagon 19 whilst it remains coupled to adjacent wagons comprises a rotatable platform 14 to which the wagon is clamped, a mechanism 38 for actuating clamping means 30, 32 being located in a position fixed relative to the tippler supports tructure, and a holding means to lock the clamping means during rotation of the platform. The rotating parts of the tippler are mounted between end frames 4 supported on rollers 8, 10 and driven through a toothed rack 11 on the frames. The platform 14 having rails 18 is mounted on links 22 pivotally suspended from the frames 4 and biased by a stop 24 so that the wagon is spaced from a side stop 28 on the frames 4 until rotation starts. During rotation, the ends 30 of clamping levers 32 gravitate into engagement with the wagon as the levers 32 are permitted to pivot about their connection 34 to the frames 4, upon relative movement between the lever cam profile 36 and its engaging cam roller 38. The holding means comprises a piston 40 displaceable in a cylinder 42 by the pivoting movement of the lever 32 to transfer hydraulic fluid between opposite sides of the piston through a closed circuit including an accumulator 46 and a valve 48. The latter is actuated by a stop 52 as the apparatus rotates, and this blocks the circuit and locks the piston whereby the clamp 30 is held operative during the tippling operation. In further embodiments, Figs. 4, 5, 6, 7 (not shown), the clamping lever is moved into the operative position by an hydraulic pusher fixed relative to the tippler support structure and instead of the wagon swinging into contact with the side stop during rotation, the side stop is moved into contact with the wagon either by gravity when hydraulically released, or by an hydraulic pusher fixed relative to the tippler support structure, the stop being locked in its wagon engaging position by closed circuit hydraulic means as used on the holding means. In another embodiment (not shown) the holding means comprises either a screw or over centre toggle arrangement.

Title: Feeding device for use in the weighing of material such as solid fuel
Inventor: SMITH WALTER ARTHUR
IPC: G01G13/08
Filed: 1961-06-07
Abstract: 948,663. Automatic feed weighers. CHARROLD Ltd. June 6,1962 [ June 7,1961], No. 20504/61. Heading G1W. In an automatic feeding device, for use in the weighing of material such as solid fuel, material from a hopper 1 (Fig. 1) is fed on to a plate 8 and from thence it falls to a plate 4 to which the plate 8 is attached by brackets 7. The rear end of plate 4 is supported on rollers 5, while its front or discharge end is supported on links 6 and connected to a motor driven eccentric whereby the plate is given a reciprocating motion. The links 6 cause it also to rise and fall thus conveying material toward the discharge end and into a weigh container (not shown). The plate 8 reciprocates with plate 4 its free end being supported on rollers 9. When almost the desired weight of material is in the container the weighing scale (not shown) operates a switch to energize a solenoid 40 which releases a latch on a door 34 allowing it to fall until the brush 35 thereon engages the plate 4. Further discharge from plate 4 is thus prevented. The container may then be topped up manually, or automatically by means of a dribble feed trough 20 mounted to receive some of the material falling toward plate 4. The trough is fixed to the plate 4 and reciprocates therewith and the arrangement is such that when the door 34 falls on the plate 4 material can be discharged from the narrow end of the trough 20 to the weigh container. A second gate member 42 connected by links to the door 34 closes at the same time as door 34 and prevents further feed from the plate 8 to the plate 4. A trickle feed is possible, however, through a central adjustable aperture (Fig. 4, not shown) in the gate member 42, to the trough 20. When the correct weight is in the container a switch operated by the weigher stops the motor. Alternatively the dribble feed trough may be mounted below plate 4 (Fig. 6 not shown) in which case material falls through a slot or slots in plate 4 to the trough. Specification 948, 664 is referred to.
