Abstract: 248,651. Fornaca, G. Sept. 10, 1925. Spray carburettors.-In carburettors adapted to be supplied with a light fuel at starting and a heavier fuel for normal running, the change over from one fuel to the other is effected from a distance by fluid.pressure-actuated means. The carburettor 1, Fig. 2, has chambers 7, 8 for light and heavy fuel respectively and conduits 2, 3 lead from these chambers to the casing 5 of a cock 6, Fig. 3, which communicates through a conduit 4 with the fuel nozzle. The cock has an arm 10 connected through a rod 11 to a piston 12 working in a cylinder 13. the piston being urged by a spring 15 towards that end of the cylinder to which is connected a fluid-pressure pipe 14 provided with a manually actuated valve. With no pressure fluid, the piston is moved to the right and the light fuel conduit 2 is in communication with the conduit 4. The device is particularly applicable to railroad cars where the driver may sometimes be at a considerable distance from the engine. In such application the pressure fluid may be derived from that actuating the brakes.

Title: Improvements in or relating to Rotary Meters for Measuring the Mass Flow of a Stream of Fluid
Inventor: MAURER ROBERT
IPC: G01F1/80
Filed: 1966-05-20
Abstract: 1,199,002. Rotary mass-flowmeters. R. MAURER (CONSULTANTS) Ltd. Aug. 21, 1967 [May 20, 1966], No.22703/66. Heading F1F. A rotary mass-flowmeter 210, Fig. 1, comprises a two-part cylindrical housing 211 having an enlarged diameter bore portion 212 and a fixed hollow concentric body 214 supported by axially directed inlet vanes 216 and outlet vanes 227. With the enlarged bore portion 212 is mounted a by-pass valve comprising a fixed inner sleeve 231 and an axially movable spring-loaded outer sleeve which according to the flow-rate through the meter divides the flow between an inner annular chamber 239 having fixed axial-flow vanes 232 and fixed inclined swirl producing guide vanes 217 and an outer annular by-pass chamber 241 having fixed flow straightener vanes 243. The two flows then combine in a mixing chamber 244 and pass through axially directed vanes 219 of a freely rotatable speed paddle having a pick-off 221 connected to a computer 245 to measure the swirl velocity of the fluid leaving the mixing chamber and axially directed vanes 223 of a torque paddle mounted on a shaft 224 which at its forward end carries a torque meter 229 having a power takeoff 230 connected to the computer 245 to feed into the computer the torsional reaction of the fluid leaving the mixing chamber. The quotient of the swirl velocity and the torsional reaction of the fluid gives the mass-flow through the meter. The by-pass valve which opens on increasing flow-rate to increase the flow through the by-pass reduces the torque range to acceptable limits for an extended flow range and maintains meter accuracy over a wider range of flow-rates. Trimmer vanes 246 are provided to compensate for any misalignment between the vanes of the two paddles and are set during calibration of the meter. The vanes of the two paddles need not be axially directed but must be of identical inclination. Modifications show and describe modified constructions of bypass valves. In one, the movable sleeve is controlled by the computer which through a motor and worm gearing moves the sleeve axially. In another, a coil spring when fully compressed seats on an abutment on the forward end of the enlarged bore portion 212. As flow increases the spring coils move apart to permit flow therethrough to the outer annular by-pass chamber.

Title: Device for emitting mechanical waves
IPC: G01V1/116
Filed: 1975-05-23
Abstract: 1504324 Seismic source SOC NATIONALE DES PETROLES D'AQUITAINE 23 May 1975 [31 May 1974] 22724/75 Heading G1G A seismic source of the type in which highpressure combustion products are released abruptly from a chamber into an external medium through a valve is characterized in that the movable member of the valve comprises a piston having two faces, one face forming a movable wall of the combustion chamber and the other face forming a movable wall of a chamber for high-pressure fluid to hold the valve member against a seat, the valve member and seat having frusto-conical surfaces which face each other. In the Fig.1 embodiment, piston 25 has a face 30 which can be brought against valve seat 11 to seal off combustion chamber 5 when high airpressure is applied via duct 12 to the top face of piston head 26. The same pressure forces up a second piston 32 to force fuel from cavity 17 into the combustion chamber via at least one injector 24. Air for the combustion is admitted through duct 6 and an igniter 9 is actuated. If the combustion pressure is sufficient to create an upward force on face 30 greater than the force acting downwards on piston head 26 the piston moves upwards to release gas automatically through the valve to generate an acoustic pulse; if not, then a further valve 15 is opened to vent air from the cavity 35 and so allow the piston 25 to move upwards to release the gas from chamber 5. Alternative combustion chamber and piston valve shapes and dispositions are used in further embodiments, Figs. 2 and 3 (not shown).

Title: Robot
IPC: B25J9/18
Filed: 1976-06-02
Abstract: 1511609 Robot arm AKERS MEK VERKSTEDAS 2 June 1976 [3 June 1975] 22777/76 Heading G3N [Also in Division B8] A robot arm, e.g. for a welding tool, has two or more mutually pivotable arm sections, the mutual pivotal movement between two neighbouring arms being performed electromechanically at the joint, e.g. using an electric motor. The arm has a mechanism 9 including a DC motor, with a tachometer, which causes central pivoting of the arm about the vertical axis Fig. 3, (not shown). The shoulder joint 28 has a horizontal pivoting axis Fig. 4, (not shown) and includes an electric motor for pivoting overarm 12, which comprises two parallel arms 12a, 12b. This connects to elbow joint 27, having the same construction as shoulder joint 28, and supporting arms 15a, 15b of underarm 15 (described in detail), Fig. 5, (not shown) which support wrist joints 19, 26 whose pivoting axes are parallel to the pivoting axis of elbow joint 27. The wrist joints also have electric motors, and tachometers and support arm 21 holding welding tool 22. In another embodiment Fig. 9, (not shown) an upper central joint 300 can be provided after wrist joint 19. An electrode reservoir 30 has a spindle with electrode wire thereon and an electrode feeding device 7 is provided on the other side. All joints have adjustable frictional couplings to protect the drives against overloading. Micro-switches can stop the motors in emergency conditions and the arm is made of aluminium to reduce the weight. All pivoting joints are arranged in position feedback servoloops (Fig. 7). The output from computer 100 passes via D/A converter 101 and amplifier 102 to amplifier 103, which also receives the output of tachometer 106, and whose output controls motor 105. Angle transducer 108 gives the angular turning of the joint relative to the preceding arm and this is converted to a digital signal in unit 109 and passed to the computer. Thus the arm is moved in a path controlled by the computer program. It can also be controlled from a manually operated panel. The arm can be fixed to walls, floors or ceilings and the stem 4 can have an electrically driven telescopically extendable unit controlled from the computer Fig. 8, (not shown). The welding head can perform pendulum motion e.g. under computer control. Automatic path corrections can be effected during welding by sensing deviation between programmed and actual welding paths, the computer providing the necessary corrections. The computer can control several robot arms and can be programmed by leading an arm through the desired path sequence, the joints having releasers which reduce frictional coupling thereat during teaching.

Title: Improvements relating to electrically-operated pumps
Inventor: MORRIS JOHN NEVILLE
IPC: F04B17/04
Filed: 1956-07-28
Abstract: 811,746. Diaphragm pumps. S. U. CARBURETTER CO. Ltd. July 15, 1957 [July 28, 1956], No. 23388/56. Class 102(1). [Also in Group XXXV] An electrically operated pump comprises a magnetisable plunger 1, reciprocated by the conjoint effect of a spring 19 and an intermittently energized solenoid 3, which transmits its movement through an intervening entrapped body of low viscosity liquid to a diaphragm 49 which pumps liquid from an inlet, through a filter 59 and inlet valve 57 to the outlet port valve 58. The plunger 1 reciprocates in a non-magnetic barrel 2 within a space hermetically sealed by the pump diaphragm 49 at one end and a diaphragm 13 at the other, the opposite side of diaphragm 13 being vented to the atmosphere. Spaced from the plunger by a non-magnetic spacer 25 is a permanent low magnetic 23 having pole-pieces 22 and 24. In operation the plunger 1 and magnet 23 moves downwards under the action of spring 19 to provide the discharge stroke and the pole-piece 24 attracts arm 43 of the switch mechanism (see Group XXXV) which causes the solenoid to be energised, this causes upward movement of the plunger until the pole-piece 22 attracts arm 47 of the armature thus breaking the supply to the solenoid. The plunger is prevented from contacting the diaphragm at all times by a perforated plate 50, the plunger does not normally touch this plate when operating but rests on it when the pump is not in use. When the pressure in the outlet pipe is sufficient to prevent a full stroke of the diaphragm 49, the pressure of the low viscosity liquid in lower zone 67 will rise with downward movement of the plunger 1 and some of this liquid will leak past the plunger to the upper zone 68. A non-return valve 69 is provided in the plunger 1 to allow low-viscosity liquid to pass from the upper zone 68 to the lower zone 67 on upward movement of the plunger at a predetermined pressure difference thus preventing hydraulic locks of the plunger. The diaphragm 49 is preferably made of nylon sheet or corrugated metal and both diaphragm 13 and 49 are preferably clamped at their outer ends by rings 14 and 51 respectively.
