Title: Crop treatment devices
IPC: F26B17/02
Filed: 1974-05-24
Abstract: 1430893 Drying C VAN DER LELY NV 24 May 1974 [28 May 1973] 23457/74 Heading F4G A crop treatment device comprises a chamber 1 and conveying mechanism for conveying crop through the chamber, the conveying mechanism comprising a wholly or partlybodily displaceable feeding assembly for supplying crop at one end of the chamber and uniformly over the width thereof. The bulk supply chamber 1 has an endless driven flow conveyer 14 extending the length of the chamber, an endless conveyer 25 with tines for lifting the crop fed to the rear end of the chamber by the conveyer 14 and for letting it fall on to an endless transverse belt 36 which feeds the crop to an external inclined endless belt conveyer 47 with transverse tines which deposit the crop on to an endless transverse conveyer 51 which bodily reciprocates out of and across the chamber floor and uniformly spreads the crop thereon. The conveyer 51 passes round end rollers 55 mounted in bearings on beams 60 one roller 55 being driven by a reversible motor 95 which also drives a sprocket 68 around which and sprocket 69 an endless chain 73 passes. The chain is connected to an arm 74 secured to a fixed channel guide 67 above the chamber 1 whereby the conveyer 51 is bodily reciprocated. The beams 60 have rollers 66 running along the guides 67. By turning a rod 87, which has an end bevel gear which engages a bevel gear on an end of a threaded rod on which a nut on one end of the arm 74 is displaceable, the amount of displacement may be varied. A control member 99 is connected to a clutch for the sprocket 68. Alternatively an endless driven conveyer 134 is stationary and a plate 135 beneath the conveyer is reciprocated beneath rollers 136 in the guides 67 by connecting it by a support 137 and pivoted arm 139 to an endless driven conveyer 140. If the conveyer 25 deposits excess crop, rods 111 pivot and actuate a switch to stop a motor 119 which stops the conveyers 25 and 26. Elevator 45 continues and clears the blockage then the drive to the conveyers recommences. The drive shaft 23 for the conveyer 25 has a clutch operated by a rod 121. The shaft 23 is driven by the electric motor 129 which also drives the conveyer 36 and an auger 128. Hot air is supplied by a heating system 132 and a blower 131 through a duct 130 to a chamber 129 the hot air passes between floor elements 7 and spaced beams 13 of the conveyer 14 then through the crop and escapes through a gauze 4. By tilting a flap the conveyer 51 discharges dried crop to the chamber 129 where a suction duct 144 withdraws the crop and feeds it to an external bin. The conveyer belt 39 may also discharge the crop.

Patent GB-861926-A (GB)
Title: Parallel adders for binary numbers
Inventor: STEAGALL WILLIAM FRANCIS
IPC: G06F7/38
Filed: 1957-07-25
Abstract: 861,926. Magnetic amplifiers. SPERRY RAND CORPORATION. July 25, 1957, No. 23562/57. Class 40 (9). [Also in Group XIX] A complementing magnetic amplifier which may be used in a parallel adder circuit (see Group XIX) comprises a core 20, Fig. 2, with a winding 21 to which power pulses A, Fig. 3, are supplied. Normally the core remains in one saturated state of magnetism and a substantial output pulse is developed across a load R L  in response to each A pulse. However, when an input pulse C, Fig. 3, is applied to a second winding 22 it reverses the state of the core and the next A pulse meets with high impedance in the winding 21 while returning the core to its initial state. In this case no effective output is available across R L . To suppress any vestige of a pulse in these circumstances a diode D5 and resistor R1 pass a permanent current greater than that of any sneak pulse, between earth and - V. A further diode D4 and resistor R2 suppress pulses induced in the winding 22 by A pulses in winding 21. A non-complementing amplifier which may also be used comprises a core 40, Fig. 4, with a winding 41 to which power pulses A, Fig. 3, are supplied via terminal 43. Normally these pulses change the state of the core (cf. above) and therefore no output pulse is developed across a load R L . The core is returned to its opposite state of magnetism by the effect of the negative half of the A pulse which causes a reverse current to flow in the winding 41. However, an input pulse C, when applied to a winding 42, cancels out the effect of the negative half of the A pulse, thus leaving the core unchanged, so that the next positive A pulse, meeting a low impedance in the winding 41, develops an output pulse across the load R L . Means for suppressing spurious pulses in this example include a diode D8 and connection of one end of the winding 42 to a positive source + E.

Title: Improvements in locating and locking means
IPC: B24B53/12
Filed: 1945-09-14
Abstract: 623,726. Hinges. KESTELL, T. A. Sept. 14, 1945, No. 23827. [Class 65 (ii)] [Also in Groups XXI and XXII] A tool-holder 4 (see Group XXII) hinges about a sleeve 6 surrounding a central pivot 7 on a base 29 and is adapted to be located and locked in a predetermined position. The sleeve 6 is slidably keyed to a collar 30 which carries a handle 5 and is adjustable in position by a nut 26 ; the threaded upper portion of the sleeve 6 engages a nut 20 on the holder 4 and it is formed at its base with a recess 9. The holder carries on its base a member 13 slotted to receive a pin 10. In operation, the holder is unlocked by turning the member 6 anti-clockwise, Fig: 2, so that the pin 10 engages the recess 9, and the holder is carried round by a pin 12 on the sleeve until a stop 14 is reached and the holder is held in position by a spring- plunger 15. To lock the holder, it is carried round by the pin 10 until the latter engages a recess 11 in the base, and the member 13 abuts a stop 19. Further rotation of the handle forces the pin into the recess 11 by means of an eccentric surface 8 on the sleeve, and the rotation of the sleeve 6 in the nut 20 clamps the holder down onto the base. The invention may also be applied to gun-breech mechanism, instruments and other obturating devices.

Title: Improvements relating to the manufacture of naphthalene
Inventor: VINCENT MAURICE WILLIAM
IPC: C07C7/14
Filed: 1956-08-02
Abstract: Crystallised naphthalene is purified by treating the cooled slurry from the crystallising stage in a first continuous or semi-continuous separator, forming a slurry of the crystals with water or an aqueous solution, adjusting the temperature of the slurry to a controlled temperature slightly below that of the grade of naphthalene required, and then treating in a second continuous or semicontinuous separator. The process may be repeated.  Liquid from the separators may be separated in liquid/liquid separators to obtain oil which is returned to the crystallisation and water or aqueous solution which is reused for washing.  The naphthalene may also be treated with sulphuric acid followed by caustic soda solution or water.  The naphthalene may be dried by melting and separating from water in a liquid/liquid separator.

Title: Improvements in and relating to modulated carrier-wave transmission systems
IPC: H03C1/04
Filed: 1939-08-21
Abstract: 532,204. Wireless transmitting systems. SANDEMAN, E. K. Aug. 21, 1939, No. 24082. [Class 40 (v)] Relates to modulated carrier wave systems in which different parts of the modulated wave are communicated to the load through different amplifying chains, and consists in reducing distortion in such systems due to differences in the envelope phase shift in the respective chains. The differences arise for the most part in the amplifiers following the modulating stage, and are due to the upper side frequencies being shifted in phase through a different angle from the corresponding lower side frequencies. The distortion is reduced by inserting a phase-shifting network in the high-frequency part of one or both of the amplifier chains. When each chain has its own modulation-frequency apparatus, suitable networks may be provided therein. Further distortion arising from the respective chains responding differently to different envelope frequencies may be avoided by arranging that the efficiency of each high-frequency channel is the same at all relevant side-band frequencies. Alternatively, correction may be effected in the low-frequency circuits or partly at high and partly at low frequencies. Negative feed-back may also be used.

Title: Improvements in and relating to on-load tap changing gear
Inventor: PEEL ROBERT FREDERICK CRESWELL
IPC: H01F27/40
Filed: 1962-06-22
Abstract: 982,262. Transformers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 31, 1963 [June 22, 1962], No. 24147/62. Heading H1T. A tap changer control arrangement includes a group of control contacts coupled to move with a group of movable contacts, connected in parallel, of a group of tap changers, which may operate on the windings of separate transformers, the control contacts completing the energizing circuit of a coil controlling the movement of a tap changer when two or more of the group of movable tap changer contacts get out of step by two or a multiple of two, steps. In one arrangement the movable selector contacts 7-10 (Fig. 1) on potentiometers 1-4 are coupled with the associated movable contacts of the tap changers so that the voltages in any position correspond to those provided by the tap changers. The movable contacts 19-22 of control switches COS1-COS4 are coupled to the various tapchangers, so that when the latter progress one step, the movable contacts change over, engaging linked fixed contacts E1-E4 at an even step, and O1-O4 at an odd, step. Only when one tap changer with its associated contact 7-10 is two steps out of line with the other tap changers, will a voltage difference be obtained to energize the appropriate coil 15- 18. The coils may form part of relays in the control circuit of electric motors driving the movable contacts. As the relays are energized, an on-load tap changer drive can be stopped to prevent damage by further on-load tapchanging. In another arrangement (Fig. 2, not shown), the potentiometers are dispensed with, additional change-over switches COS1a-COS4a, each having one contact connected to a supply, and which change over at each second tapping only, being connected between switches COS1- COS4 and the operating coils. Conductor G4 may provide simultaneous energization of all coils. The coils may operate one or more relays controlling the tap-changing tripping coils of circuit breakers and alarm and indication devices.
