Filed: 1936-11-24
Abstract: 485,389. Actuation of switches. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 24, 1936, No. 32144. Convention date, Nov. 26, 1935. [Class 38 (v)] [Also in Group XXXVI] A differential fluid pressureactuated switch comprises bellows 16, 17, Fig. 1, connected to different sources of fluid pressure and joined by a rod 18 to which a lever 19 operating a mercury switch 29 is pivoted. The bellows 16 is of larger diameter than the bellows 17 so that when the pressures in the two bellows are equal the lever 19 maintains the switch in the position shown in full lines in Fig. 13. The switch remains in this position until the pressure in the bellows 16 falls, relatively to the pressure in the bellows 17, by an amount determined by the difference in cross-sectional area of the two bellows, when the rod 18 then moves to the right and trips the switch into the position shown in dotted lines. The lever 19 may be biassed by a spring 19a. In a modified construction the bellows are mounted side-by-side and action a lever adjustably pivoted between them, the lever operating the mercury switch. In another construction, Fig. 10, bellows 60, 61 carry racks 62, 65 operating on coaxial pinions 63, 65 carrying switch contacts 67, 68. A number of interconnected switches may be arranged in one casing, for example, as shown in Fig. 1.

Title: An improved device for metering a flow of liquid
IPC: G01F3/38
Filed: 1955-11-12
Abstract: 831,324. Fuel - consumption indicators. SHAW, J. C. Nov. 9, 1956 [Nov. 12, 1955; Nov. 30, 1955], Nos. 32413/55 and 34243/55. Class 106 (3). [Also in Group XXIX] A liquid fuel metering device for giving electric signals corresponding with the quantity of fuel which is consumed by an engine in a vehicle, is associated with means giving signals representing the distance travelled by the vehicle to give an indication of the rate of fuel consumption. According to the first Provisional Specification a ratchet-wheel, loosely mounted on a fixed spindle, is stepped round by one tooth for each distance signal received. A radial arm, termed a speed am, is pressed against the ratchetwheel to rotate therewith until a signal pulse is received from the liquid fuel metering device when the speed arm is disengaged from the ratchet-wheel and reset under the influence of a spring, i.e. the speed arm is displaced by an amount depending upon the relationship between the speed of the vehicle and the rate of fuel consumption. The apparatus includes a second pointer adapted to indicate the previous setting of each speed arm movement. According to the second Provisional Specification the ratchet-wheel referred to above is replaced by a wheel continuously driven through gearing from a mechanical connection to the engine. Fuel meter. This comprises upper and lower chambers A and B interconnected at their upper ends by a pipe 27. As liquid enters chamber A, through a pipe 11, it causes a float 15 to rise up a stem 14 until it compresses a spring 16 against a stop 17 secured to the stem 14 sufficiently to permit a permanent magnet 20 to attract a soft iron yoke 19 secured to the stem 14. The resulting upward movement of the stem 14 (a) closes a pair of contacts 25, 26, to cause an electric signal to be made, and (b) lifts the valve 13 from its seat 12a to permit the fuel in the chamber A to pass into the chamber B. The float 15 then descends with the liquid level until it rests on the valve 13 with a force sufficient to part the soft iron yoke 19 from the permanent magnet 20, thus closing the valve 13 and opening the contacts 25, 26. The cycle is then repeated.

Filed: 1970-07-06
Abstract: 1320014 Valves ROBERT BOSCH GmbH 6 July 1970 [5 July 1969] 32646/70 Heading F2V A pressure-balanced, double-seated electromagnetically controlled valve comprises a ball valve member 7 which is movable on to a first seat 5 by means of a spring-biased stem 8 and is movable on to a second seat by fluid pressure at the inlet passage 38. The inlet passage contains a filter 29 and the valve body has formed therein service and drain passages 27 and 28, respectively. A passage 30, 31, 32 and 15 leads from the inlet to the right-hand side, as seen in the drawing, of an armature 13 secured to the stem 8, with the area of the stem end 14 being equal to area of ball 7 upon which inlet pressure acts when the ball is engaged with seat 5. In the de-energized state of the electromagnetic coil and core 19, 16 the valve attains the state shown. Upon energizing the coil, armature 13 draws stem 8 in opposition to spring 9 so permitting ball 7 to engage seat 6. The stem end 14 projects slightly beyond the associated face of armature 13 to so prevent sticking of the stem to core 16. In a modification, (Fig. 2, not shown), the ball-actuating stem is made hollow and its righthand end is made to have an area greater than the area of ball 7 upon which the inlet pressure acts. Accordingly, the stem experiences a pressure differential which at all times acts in the direction to engage ball 7 against seat 5, the spring 9 being omitted in this embodiment.

Title: Improvements relating to the harvesting of potatoes
IPC: A01D33/08
Filed: 1946-11-04
Abstract: 618,223. Potato harvester. HALDANE, J. C. Nov. 4, 1946, No. 32717. [Class 6 (iii)] A potato harvester comprises a self-propelled frame, a digging mechanism thereon, and a screening mechanism characterised in that the screening mechanism delivers all the lifted material to a tank having a liquid which allows the potatoes to float while the stones &c. sink, the tank containing means for removing the stones &c. without substantial loss of liquid and a device for removing the floating potatoes. The floating potatoes are removed, in the construction shown, by a pivoted grid 21 actuated at spaced intervals by an interrupted gear driven lug 22. The stone remover comprises a separator-conveyer 33 driven from a grate-like elevator 13 which delivers the potatoes to the tank 1. The tank is pivotally supported at its top from a gimbal frame and locked in position by a slotted disc 10 and a ratchet quadrant 9, both of which are controlled by a lever 12, the disc 10 fixing the tank to the gimbal frame, and the device 9 fixing said frame to the tractor frame. In operation, the crops are conveyed upwardly by the elevator 13 to an inclined funnel 17, being guided thereto by a baffle plate 67, which discharges them into the tank. The floating potatoes are removed by the pivoted grid down an inclined shoot 24 to a sack. Specification 601,834 is referred to. The Provisional Specification describes a modification wherein the tank is divided into a number of compartments to diminish " slopping and has a plurality of hinged flaps to remove the floating potatoes, while a bucket conveyer removes the sludge. In a further modification, the tank comprises two compartments, one above the other, which can be closed by traps. Loss of solution may be diminished by passing the sludge between rollers over a sieve.
Patent GB-887904-A (GB)
Title: Method of obtaining signals representative of scanned data
IPC: G11C13/04
Filed: 1960-09-23
Abstract: 887,904. Automatic character reading. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 23, 1960 [Oct. 17, 1959], No. 32720/60. Class 106 (1). In a character-reading apparatus, compensation for variations of background reflectivity and of blackness of the character is made by a periodic blurring of the scanning beam to sense parts of the character and its background, a signal being derived thereby which is used to set a clipping level or an amplifier gain control for the signals derived from scanning the character with a focused beam. The scanning beam, which repeatedly traverses a vertical path, is produced by a cathode-ray tube 1, Fig. 1, light being projected by lens 2 on to the moving carrier 4. A photo-cell 3 receives the reflected light and produces video signals which are amplified at 21. A second photo-cell 5 serves to maintain the brightness of the light beam constant by means of a control circuit 6. A ring circuit 17 is driven by a pulse generator 16 and the outputs on terminals 172, 173, 174 control the cathode-ray tube through control circuits 7, 8 and 10 so that when a signal appears on terminals 172 and 174 the beam is blurred so as to make a light spot having about ten times the area of the focused spot. When the signal is on terminal 173 the spot is focused. The two blurred spots are positioned at points displaced one to each side of the focused spot and they are used to derive a clipping level with which the signals derived from the focused scanning are compared. The photo-cell 3 responds to the three types of scan in turn and the amplified output is applied to the circuits 18, 19 and 20 which are enabled in turn by the signals on terminals 172, 174 and 173. The circuits 18, 19 and 20 each consist of a differential amplifier and a diode clamping circuit. During the time the circuit is enabled by a signal on the corresponding terminal of ring circuit 17, the signal from amplifier 21 is amplified and applied to the output 183, 193 or 203. For the remaining time the signal is maintained by the diode clamp. The signals on terminals 183 and 193 relating to the blurred spots are combined by being averaged in resistors 22 and 23 and the resulting signal is used as the threshold level in a trigger circuit 24 which switches from one state to the other according as to whether this level is exceeded by the video signal derived from the focused scan, and delivers a two-state output at terminal 242. Instead of being averaged the blurred spot signals may be combined in other ways. The higher or the lower may be taken or the difference may be taken and multiplied by a constant. The cycle of blurred and focused scanning points is very fast compared with the raster of vertical scans.
