Title: Direct-action compressor
IPC: F04B31/00
Filed: 1973-07-04
Abstract: 1440453 Compressors A MOIROUX and F BERNARD 4 July 1973 [6 July 1972] 33301/73 Heading F1N A compressor comprises a compression unit incorporating a piston 3 slidable in a cylinder 6, an I.C. engine unit incorporating a piston 2 slidable in a cylinder 5, and a unit in which air is compressed by the power stroke of the engine unit, the air thus compressed serving to force piston 2 back to effect its compression stroke, this last "bounce" unit comprising a piston 4 slidable in a cylinder 7, the pistons 2, 3, 4 all constituting part of a single integral member 1. Cooling vanes 13, 31 are provided around the combustion cylinder and a casing 25 which defines the bounce cylinder, a discharge chamber 32 and engine accessories including at least starting means 28. To start the compressor, compressed air in a chamber 29 is released via a valve into a starting chamber 27 to urge piston 4 to the left, valve 28 uncovering the end of cylinder 7. During movement of member 1 to the left, the chamber to the right of piston 3 draws in air through valves 22. The chamber to the left of piston 3 discharges air into an inlet reservoir 15 for the I.C. engine unit. Piston 2 performs its compression stroke, compressing air admitted from reservoir 15 into cylinder 5 via ports 12. When the compression stroke is completed, injector 9 feeds fuel to the space and combustion takes place, urging member 1 to the right. During this movement ports 34 in piston 2 co-operate with inlet and outlet ports 12, 11 to permit cooling and scavenging air to pass through piston 2 into the discharge channel 16 of the I.C. engine unit. The chamber to the left of piston 3 takes in air through valves 19, whilst the chamber to the right of piston 3 compresses the gas and discharges it into discharge chamber 32. Piston 4 compresses air in cylinder 7, the valve 28 closing the end of the cylinder. At the end of the power stroke, the air thus compressed in cylinder 7 returns the member 1 to the left and the cycle is repeated.

Abstract: 1485715 Odometers HONDA GIKEN KOGYO KK 11 Aug 1975 [15 Aug 1974(2) 33424/75 Heading G1K [Also in Division F2] A vehicle odometer has an auxiliary display to give continuous indication when one or more predetermined distances has or have been covered, to warn that a particular part or parts of the vehicle is or are due for servicing, inspection, or replacement. The odometer A has a set of digit wheels 10 rotatable to register the distance travelled by the vehicle. All the digit wheels except a selected one, e.g. the thousands order wheel, are freely rotatable on a shaft 30. The auxiliary display has at least one display wheel 40 including an inner part 41 and an outer part 42 normally connected together for rotation by a slip clutch 43, 44, the outer part 42 having a warning zone 45 on its periphery, and the inner part 41 being secured to a shaft 31. Gears 32, 34, 33 transmit the rotation of the selected one of the digit wheels 10 to the shaft 31. Gear teeth 46 on the outer part 42 of each display wheel 40 mesh with teeth 61 of a respective locking gear 60 freely rotatable on a shaft 35. A boss 63 of the locking gear carries a stop arm 64 which, when the warning zone 45 becomes positioned behind a  fisheye lens 52 in the vehicle dashboard 50, abuts a projection 71 on a push-rod 70 to lock the display wheel outer part 42 against further rotation. The slip clutch allows the inner part 41 of the display wheel to continue its rotation as it is driven by the odometer. To reset the display wheel, the push-rod 70 is moved to the left, Fig. 2, to move the projection 71 away from the arm 64 and to cause a trip 72 to rotate the arm 64, and hence the gear 60 and the display wheel outer part 42, to a predetermined starting position. The outer part 42 is then free to rotate with the inner part 41 for a fresh measuring cycle. The slip clutch may comprise springs 44 on the inner part 41 which resiliently engage in recesses 43 in the outer part 42, Fig. 2, or may have pawls 88, Fig. 8, spring urged radially outwardly of the inner part 41, or permanent magnets (47), Fig. 4 (not shown) of the outer part 42 co-operate with a set of soft iron pieces (48) evenly distributed round the inner part 41. Fig. 6 shows a modified locking and reset mechanism in which the stop arm 64 is offset laterally from the push-rod 70 and engages a flange 76 of the projection 71. The trip 72 has a cutout 77 which, for resetting, engages a cam 67 axially adjacent the stop arm 64 to precisely position the locking gear 60 in its starting position. In another modified mechanism, Fig. 8, the pushrod 80 engages a three-armed lever 82 having a stop arm 87 to engage a pin 68 on the locking gear 60, and a reset arm 85 to engage a reset cam 67 on the locking gear 60. With these two modified mechanisms, the display wheel outer member 42 can be accurately reset before the warning zone 45 reaches its display position.

Title: Process for the upgrading of rock phosphate
IPC: C05B11/02
Filed: 1960-10-03
Abstract: Upgrading of calcite-containing rock phosphate is effected by calcining the phosphate, wet-slaking the calcination product and bubbling a CO2-containing gas through the resulting aqueous dispersion at such a rate that the pH of the dispersion is maintained substantially at the magnitude it had prior to the introduction of the gas, until substantially all the Ca(OH)2 is converted into CaCO3. The calcite particles form a suspension which can be decanted from the phosphate which settles instantaneously.  Pure CO2, or any gas mixture containing at least 5% by volume CO2, may be used provided that the remaining constituents of the gas do not react with Ca(OH)2, CaCO3 or the phosphate.  Stack gas from the calcination kiln is preferably used and the carbonation usually takes from 2 to 3 hours. Four examples illustrating the invention show that the loss of P2O5 during enrichment ranges from 3,9 to 4,5% calculated on the initial amount.  Specification 731,999 is referred to.

Title: A Frequency Control Circuit
IPC: H03D13/00
Filed: 1966-08-01
Abstract: 1,159,603. Automatic frequency control systems; modulators. CIT-COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS. 1 Aug., 1966 [5 Aug., 1965], No. 34416/66. Headings H3A and H3R. In a system for locking a variable frequency oscillator O to a reference frequency oscillator R, the oscillator is swept over a wide frequency range by a sawtooth waveform applied to a varactor diode 2 until it falls within the locking range. A D.C. control signal is then derived from a phase comparator D and is applied to the diode 2 to hold the two oscillators in synchronism. When the frequency difference between the two oscillators is large, the output from the discriminator D has no D.C. component, and the amplifier Q 3  is biased to a saturated state. In this condition, a sawtooth generator comprising a multivibrator M, transistor Q 4 , and C.R. network 29, 30 applies a sweep voltage to the varactor diode 2. When the frequency of the oscillator O approached that of oscillator R, the output from the discriminator D includes a D.C. component which brings transistor Q 3  out of saturation. Q 3  now amplifies this D.C. signal, and provides a first output signal which is applied to a unit I to stop the sawtooth generator, and a second output signal which is fed via a time constant network 20, 21, 22 to the varactor diode, to lock the two frequencies. Any further deviations outside the locking range feeds a pulse via network 25, 26 to start a small amplitude frequency scan.
