Title: Improvements in cultivators and the like
IPC: A01B63/28
Filed: 1919-09-23
Abstract: 166,263. Saunderson, H. P. Sept. 23, 1919. Cultivators; motor implements; adjusting parts of implements.-Cultivators, scarifiers, grubbers, levellers, and other implements are provided with special means for raising the frame upon upright standards carrying the axle of the rear wheels. Fig. 2 shows a cultivator or grubber having a triangular frame supported on brackets f which are adapted to slide on upright standards q carrying the rear axle i. Fig. 5 shows the lifting mechanism with the frame in its highest position. The frame a is supported by lifting-chains o fastened to sprocket-wheels n on a shaft l mounted in the standards g. To raise the frame, the shaft l is clutched to a sprocket-wheel p, which is continuously driven from the wheels j by chain gearing q, r and a free-wheel clutch. The shaft l is disengaged from the sprocket-wheel when the frame has been raised by the engagement of the bracket f with a tail-piece u<5> on the cam-lever u<3> by which the clutch is actuated. This cam-lever u<3> is connected by a chain u<4> to a spring-controlled lever v pivoted on a pivoted latch w which engages a roller x on the sprocketwheel n to hold the frame in its raised position. The lever v is actuated from the tractor by pulling on a cord z. The first pull releases the latch wand allows the frame a to fall. A further pull moves the lever u<3> and thus throws the clutch into action to raise the frame. The cultivator may be converted into a grader or leveller by attaching a scoop to the rear tines d as shown in Fig. 7. The scoop e<1> is fastened between the shares e and the tines d.

Title: Portable measuring apparatus for determining the oxygen content of a gas
IPC: G01N27/74
Filed: 1967-05-22
Abstract: 1,130,416. Measuring oxygen content electrically. BERGWERKSVERBAND G, m b. H May 22, 1967 [June 15, 1966], No. 23647/67. Heading G1N. In the estimation of the oxygen content of a gas using the paramagnetic properties of oxygen, the gas is conveyed down a central passage 1, Fig. 1, between the poles 8, 9, Fig. 2, of a magnet producing a non-homogeneous field. Ducts 11,12,13 and 14 connect the passage 1, in the region of the magnetic field and above and below it, to E-shaped duct systems 6, 7 supplied via inlets 4, 5 with a reference gas of known oxygen content. Heated resistors 16, 17 each comprising two resistances a, b, connected in adjacent arms of a Wheatstone bridge, Fig.3 (not shown), are situated in the central duct of each system between inlets 4, 5 to detect flow of reference gas along the central ducts. Initially, with the oxygen contents of both gases equal, trimming valves 15 in the duct systems are adjusted until there is no flow of gas across the resistors. In operation, if for example the oxygen content of the reference gas is lower than that of the gas under investigation; gas will flow outwards along the central ducts resulting in a differential cooling of resistors b and the consequent unbalancing of the bridge by an amount indicative of the difference in oxygen contents. The parts a, b of the resistors 16,17 are so connected that transverse flow from one central duct to the other, due to rotation of the device or convection currents in the gases, resulting in the differential cooling of resistor a of one resistor and resistor b of the other, does not unbalance the bridge.

Title: Improvements in or relating to electrolytic cells
IPC: C25C7/00
Filed: 1963-06-13
Abstract: In a horizontal moving liquid metal cathode fused salt cell having an electrically conducting bottom and an electrically conducting cover supporting the anodes and inlets for the cathode metal and molten electrolyte and an outlet for the cathode metal, either or both of the anode and cathode connections are made by means of rigid conductors extending into molten metal in a container separate from the cell and having a relatively movable but fluid-tight cover, there being direct electrical contact between the molten metal and the cell cover or cell bottom. As shown, the cell cover 30 carrying the anodes 52 separated by an insulating gasket 61 from the cell 12 forms the bottom of a container 100 for molten sodium into which extend L-shaped copper strips forming the anode-connection conductor 140, a lid 115 with liquid lead seals 120 being held on the container to give a tight but sliding fit allowing movement due to thermal expansion.  The cathode-connection conductor 162 is similarly immersed in molten sodium in a container 150 into which passes an extension 170 of the cell bottom.  More than one conductor may be employed for both anode and cathode.  The liquid cathode metal, molten lead, is circulated through supply line 80 and is removed through a vertically adjustable perforated draw-off tube 94 as in Specification 1,007,778, molten electrolyte e.g. NaCl is supplied via conduit 82 and float valve 84, and a gas outlet 70 is provided in the cell cover.

Title: Improvements in combustion chambers for internal combustion turbines
IPC: F23R3/46
Filed: 1944-11-28
Abstract: 588,572. Generating combustion products under pressure. DARLINGTON, W. H., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Nov. 28, 1944, No. 23754. [Class 51 (i)] A combustion chamber, Figs. 1 and 2, for a gas turbine comprises a number of flame tubes 1, for the primary combustion of the fuel injected in the upstream direction, connected to a common annular portion 2, defining a zone for the secondary combustion of the combustion products from the flame tubes 1 with additional air, the flame tubes and annular portion being contained between inner and outer casings 45, and forming therewith passages for the air to the secondary combustion zone. The secondary air passes through the passages 12, 13 to ducts 14 leading to the secondary combustion zone. These ducts may be supplemented by one or more series of holes 14a to supply air along the length of a chamber. The flame tubes 1 may be provided with a closing plate 8 having an imperforate portion surrounded by circular rows of holes 8a for admission of primary air and are in open communication with the secondary combustion zone through holes in the spectacle plate 3 by means of which they are attached to the annular portion 2. Holes 15 in the spectacle plate may be provided for additional secondary air and may be arranged as shown or circularly disposed about the axis of the flame tube. The ends of the annular portion 2 may merge distinctly into the inlet annulus of the turbine 7 and the casing walls 4, 5 into the compressor 6 outlet annulus. In a modification, the spectacle plate 3 is connected to the inner and outer surfaces of the annular portion 2 by a conical member in which the chutes 14 are placed. In another modification, this conical member is provided with corrugations which lie between the flame tubes and gradually merge into the cylinder surface of the annular portion. The chutes 14 may be replaced by rows of holes circularly disposed about the axis of the annular portion. In still another modification, the spectacle plate is dispersed with and the flame tubes 1 are joined to a conical member which merges directly into the inner and outer surfaces of the annular portion. The flame tubes are separably and releasably attached to the annular portion so that they may be easily changed or made of a material having higher heat resisting qualities than that of the remaining parts of the combustion chamber. The outer conical surface of the flame tubes may also be perforated to provide additional primary air to the tube. Specification 587,083 is referred to.

Title: A Ciphering Machine.
Inventor: FLORIN BENGT
IPC: G09C1/08
Filed: 1966-05-27
Abstract: 1,152,707. Ciphering machines. TRANS. VERTEX A.B. 27 May, 1966, No. 23819/66. Heading G5X. A ciphering machine comprises a number of coding discs each positioned in response to the setting of individually set pin wheels; and a mechanical scanning device which simultaneously scans the coding discs and stops at a position dependent on the setting of every disc. As described, seven pin wheels 8 visible through a window 151 are initially set to a key position by means of setting wheels 31 which project through the casing. Each pin wheel has a different number of pin positions 15 and at each position a pin projects from one side or the other of the wheel. Levers 37 biased by springs 38 sense the presence or absence of pins on one side of each wheel and set a corresponding rotatably mounted pair of coding discs 42 to one out of two angular positions. At the beginning of each machine cycle, initiated by operation of one typewriter key the code wheels 8 are automatically rotated through one pin position so that a new set of pins is sensed and the code discs 42 are repositioned. The code discs are of annular form and carry coded recesses 70, the second disc of each pair being mounted for rotation with the first disc of that pair and carrying complemental recesses. During each machine cycle a shaft 56 is rotated in one direction or the other and spring-pressed scanning bails 60 to 67 each sense the apertures of one disc of each pair and enter an aligned set of recesses to stop shaft 56. Thus shaft 56 is rotated through an angle corresponding to the coded setting of the discs. A message to be ciphered or deciphered is typed on keys 113. A depressed key displaces a characteristic combination of five slide bars (105) (Fig. 4, not shown) which set corresponding members (98) which in turn determine the extent of rotation of a shaft (86) and thus the setting of a print wheel 88 to the corresponding character, in a manner similar to the setting of the shaft 56. After each character has been printed a clutch is engaged and the next rotation of shaft 56 is superimposed on the rotation of the shaft (86) thus adding or subtracting the rotation of the shaft depending on whether the machine is in the ciphering or deciphering mode. The resulting character is printed out by a typewheel 87.

Title: Improvements in servo-assisted control systems
IPC: F15B9/12
Filed: 1938-08-16
Abstract: 510,300. Fluid-pressure servomotor-control systems. SPLADIS SOC. POUR L'APPLICATION D'INVENTIONS SCIENTIFIQUES. Aug. 16, 1938, No. 24175. Convention. date, May 30. [Class 135] A servo-assisted control mechanism for controlling the steering or stabilisation of air, land, or water-craft comprises a valve device 13, Fig. 2, which is adapted to be actuated, to control the pressure of liquid supplied from pumps 24, 24<1> to the two sides of a power device 23, by, a control member such as the joystick 14 of an aircraft. The joystick is connected to one end of a floating lever 12, the other end of which is connected to both the power device and the operating rod 19 of the rudder. Intermediate its length the lever 12 is connected to one end of a lever 5 of the valve device 13, which is shown in detail in Fig. 3, which lever is pivoted at B<1> and its other end arranged between two valve members 3, 3<1>. These valves control the flows from branch conduits leading from the pump supplies to the two ends of the power device so as to vary the pressures on the two sides of the power piston 22. Manual effort applied to the joystick 14 reacts back upon the lever 5 to move one of the valves' 3, 3<1> in a closing direction against the pressure developed thereby and open the other a corresponding amount to bring the power device 23 into operation to assist in the actuation of the rudder. The pressure difference developed. in the power device is thus proportional, to the effort applied by the operator and the movement of the power device provides a " follow-up " to restore the valves 3, 3<1> to their neutral positions. In the event of failure of the liquid pressure supply the operator can assume complete manual control. Movement of the joystick 14 in a perpendicular direction operates in a similar manner through a servo-assisted mechanism to control the transverse equilibrium of the craft. In this case however, instead of the floating-lever system 12 for actuating the valves 3, 3' a differential gear train 37 is employed as shown in detail in Fig. 8 in connection with a vehicle steering gear. Manual rotation of the shaft 28 by the driver is transmitted to the steering worm wheel 33 through a pinion 27, planet pinions 29a, 29b in a casing 34, and a pinion 30 on a shaft 31. The manual effort reacts against the casing 34, a limited movement of which is adapted to actuate the lever 5 of a valve device 13, as previously described, to bring a power device into operation to drive the shaft 31 and wormwheel 33 to assist the manual effort and provide a "followup" by restoring the casing 34 to a neutral position.
