Abstract: 1,194,036. Tunnel kilns. GIBBONS BROS. Ltd. 10 Sept., 1968 [22 Sept., 1967], No. 43154/67. Heading F4B. A tunnel kiln which comprises a central furnace chamber disposed between an elongated pre-heating inlet chamber (see Fig. 3) and an elongated cooling outlet chamber (see Fig. 5) with conveying means 10 extending through all of said chambers, is characterized by the provision of means for passing into said outlet chamber a quantity of cool gas to pass over the work therein so as to cool same and thereby become heated, means for selectively extracting said heated gas from one or more of a plurality of areas within said outlet chamber to control the temperature distribution therein, and means for selectively supplying at least part of said extracted heated gas to one or more of a plurality of areas within the inlet chamber so as to control the temperature distribution therein for preheating the work. As shown, in the cooling zone 19, cool air is fed through ducts 35 in roof sections 22a into cavities 38 extending  longitudinally on each side of the tunnel, the air in the cavities 38 being extracted through a plurality of ports 40 in communication with flues 41 in the base 20 of the kiln. The ports 40 are each controlled by an individual damper plate 46. The flues 41 lead to an extraction chamber from which air is extracted by a fan (not shown). The exit end of the outlet chamber through which the cooled ware leaves the kiln is open so that air can flow into the tunnel in counter flow to the ware. The air from the said extraction chamber is passed into flues 49 in the base 20 of the kiln which extend along the latter to a distribution compartment (50, Fig. 2b), four flues (51) extending from the said compartment under the main firing zone (16) to the pre-heating zone.

Title: Control mechanism for a fuel injection system
IPC: F02D1/00
Filed: 1961-12-05
Abstract: 999,786. Regulating I.C. engines. BORG-WARNER CORPORATION. Dec. 5, 1961 [Dec. 22, 1960], No. 43579/61. Heading F1B. In an idle control mechanism for an I.C. engine fuel injection system having an airintake manifold 39 and an air throttle valve 52, a manifold pressure responsive servomotor 13 moves a member 24, connected to control the output of a fuel metering device 11 and an idle enrichment servomotor 14 including a flexible diaphragm 42 responsive to a differential pressure determined by the air throttle valve position exerts a force tending to increase fuel delivery when the engine is running during closed throttle condition. Air-intake manifold pressure during normal running is transmitted through conduit 37 to cavity 31 and the differential pressure across diaphragm 32 tends to move shaft 24 and cam 20 to the left against the action of spring 34 to reduce the output of fuel injection pump 11. During idling with air-throttles 51, 52 closed, the pressure upstream of valve 52 is communicated via port 61, cavity 58 and conduit 49 to cavity 41 so that the differential pressure across diaphragm 42 tends to move plunger 43 to increase fuel output. When valve 52 is opened the pressures at ports 60, 61 are substantially the same as the air -intake manifold pressure so that the differential pressure across diaphragm 42 is removed and the idle enrichment servomotor becomes inoperative.

Title: Speed regulator for a gas turbine operated with fluid fuel
IPC: H02P23/16
Filed: 1962-11-21
Abstract: 955,457. Valves. ADOLPH SAURER Ltd. Nov. 21, 1962 [Jan. 29, 1962], No. 44007/62. Heading F2V. [Also in Division G3] The main shaft 2 of a gas turbine drives both a fuel pump and an electric generator, the generator being connected to an electromagnetic control valve 12 for the fuel supply to the combustion chamber. When the turbine is operated at a desired speed, the fuel, which enters the valve through duet 11, is adjusted to the correct rate of flow by piston 16 co-operating with surface 17. The fuel leaves the valve through duct 13 bored in the shaft 2. If the turbine speed now increases, the generator voltage rises and solenoid 15 moves armature 20 against the force of spring 21 to throttle the fuel supply. Similarly, if the speed is reduced, the piston 16 is moved to allow the passage of more fuel. If the solenoid circuit is broken, the spring 21 pushes armature 20 and piston 16 against surface 18 so that the fuel supply is interrupted. A damping member 30 is positioned between springs 21, 31. The generator forms, with the solenoid 15, a circuit including a variable resistor and a switch.

Title: Automatic thinning device for agricultural row crops
IPC: A01B41/04
Filed: 1972-09-22
Abstract: 1408915 Automatically thinning plants AGROSTROJ JICIN NARODNI PODNIK 22 Sept 1972 [23 Sept 1971] 44062/72 Heading A1B An automatic agricultural thinning machine for row crop, particularly sugar beet, comprises an electroconductive feeler 30 which completes a circuit each time it contacts a plant such that thinning blades 27 are caused to rotate through a fraction of a revolution whilst the feeler completes a full revolution. The blades and feeler are respectively rotated upon inner and outer driven shafts 26, 29 under the control of the impulses from the feeler. Each time the feeler contacts a plant the completed circuit causes electromagnet core 14 to depress a control lever 13 which then disengages from an abutment stop 12 fixed to a spring-loaded pawl 10. The pawl thereby pivots to engage claws 8 on the inner surface of a drive ring 7 which is constantly driven by shaft 6 from drive shaft 1. The consequential rotation of the pawl 10 with the ring 7 causes shaft 9 to rotate whereupon drive is transmitted to the thinning blades and feeler by respective pairs of intermeshing gears 23, 25 and 24, 28 and the shafts 26, 29. Rotation of the feeler breaks the electrical circuit since movable electrical contact 31 fixed on the shaft 29 no longer contacts fixed electrical contact 32. Rotation of the blades and feeler stop when an abutment cam 19 presses the control lever back by means of its engagement with a spring loaded abutment lever 16 which is pivoted to the control lever 13 and engageable with an adjustable stop 18. This disconnects the pawl and ring. Inadvertent backward movement of the driven shaft 9 and associated members is prevented by the engagement of a spring loaded stop pawl 21 and an abutment face 20 of the cam 19. A leaf detector 34 is provided. The three blades 27 shown each complete 1/3 revolution per feeler revolution.

Title: Method for the production of coffee aroma extracts
IPC: A23F5/48
Filed: 1963-11-13
Abstract: The process of the parent Specification is improved by introducing a fractionating column after the steam distillation of the roasted coffee.  The co-distilled volatile coffee constituents and volatile organic acids from the steam distillation process are passed through the fractionating column whereby they are further separated the volatile organic acids collecting in the bottom of the column and the volatile coffee constituents collecting in the top of the column from where they are removed and condensed at a temperature of 35-70 DEG F. and combined with the water soluble solids extracted from the roast coffee particles and freeze or spray dried to give a water soluble coffee product.  The steam distilled volatiles may be mixed with coffee oil prior to fractionation or prior to combining the condensed volatiles with the water soluble solids.  The fractionating column has a length 5 to 20 times its cross-sectional area and may be cooled (e.g. with water) prior to introduction of the volatiles.  The process may be made "continuous" by using a continuous reflux system induced by an external condenser.

Abstract: 1399705 Injection moulding machines SANDERS ASSOCIATES Inc 29 Sept 1972 [12 Oct 1971] 45186/72 Heading B5A [Also in Division G3] In a process of injection moulding, flow of the charge is controlled until all the cavities of the die are filled, after which pressure applied to the charge is controlled. The system comprises a flow rate signal generator 13, a pressure signal generator 14 both giving the required characteristics of the charging operation, and torque motors 17, 18 responsive to the signals to actuate flappers 57, 85, the fluid output signals from one of the flappers controlling the spool 31 of a main control valve 12 depending upon the position of a transfer valve 23, whereby the control valve controls the motor 11 used for the charging operation. Initially the valve 23 is to the left (as viewed in Fig. 2) to connect lines 58, 59 to the control chambers 44, 43 respectively of the spool 31. The lines 75, 76 measure the pressure drop across an orifice 47 connected to the load, and provide a feedback to the flapper 57. When a predetermined pressure is attained in the conduit 37, a rod 105 acting against a snap-action switch 108 moves to the left and carries with it the spool 95 of the valve 89. Consequently the valve spool 61 of valve 23 is shifted to the right so that the main spool 31 now moves in accordance with pressure signals from the second flapper 85. In addition the spool 95 coacts with the flapper so that feedback from the line 107 is operative. The switch 108 enables a single signal generator to be used (Fig. 4, not shown).
