Title: Improvements in or relating to gauges
IPC: G01B3/18
Filed: 1919-09-19
Abstract: 155,894. Smith, J. C. Sept. 19, 1919. Linear-dimension gauges of screw micrometer type, provided with a ratchet head which slips when a predetermined turning-effort is applied to the thimble, have the slip device formed of opposed ratchetwheels pressed together by a coiled spring placed between one of the ratchet-wheels, and an adjustable collar. The invention is described in connecton wth a gauge fitted with the indicating-gear described' in Specification 156,057, and with the adjustable gap devices. A spring 14 surrounds the anvil 9 and abuts at one end against an adjustable collar 14<a> and at the other end against a sliding toothed collar 1-5 which does not rotate relatively to the thimble, and which engages a similar toothed ring 21 fixed to the thimble 19. When the pressure of the spring is overcome, -the thimble rotates without affecfing the spindle. The spindle is surrounded by a sleeve 12 fitted with two keys, this sleeve being in turn surrounded by two short sleeves carrying the indicating-dises 'of lowest denomination and surrounded by extra tubes carrying the first toothed wheels of the indicator gear, angular adjustment thus being provided for. '.The spindles for the various indicating discs 33, 34 &c. and the short sleeves are mounted 'between the partitions 5 and the ends of a casing 2 and the train of indicating -gears embody -elliptical wheels so arranged that 'the higher wheel is always operated at the maximum speed of the driver so that a quick transfer is given and any back lash is taken up. 'Two sets of gears and indicating discs-are shown, one adapted for inches and one for metric units, the necessary slight difference due to both sets being actuated from the screw being compensated by one of the keys on the spindle 12 engaging a helical groove in one of the short sleeves. A clamping nut may be provided on a screwed and split boss on the casing to lock the instrument for repetition work. A glass cover is provided, suitably darkened, except at reading openings for the indicating discs, such cover being secured by screws and ,sealed against tampering. The casing 2 'has two lugs 3 to which interchangeable .shoes 4 are attached which together, with interchangeable fixed anvils 70, afford means of varying the gap of the gauge. In a modified form of friction head, a loose ratchet collar the faces of which have oppositely arranged ratchet teeth, one set of which are steeper than the other, is arranged between the collar 14a and the ratchet 21. Specification 6590/93 also is referred to.

Abstract: 759,583. Governor transmitting mechanism. ROLLS-ROYCE, Ltd. Oct. 8, 1952 [Oct. 8, 1951], No. 23425/51. Class 57 [Also in Groups XXIX and XXXV] The output torque of an eddy-current coupling (see Group XXXV), for use in governing the fuel supply and speed of a jet-engine, is dependent on the speed of the input member and also on its rate of change of speed for the purpose of reducing hunting of the governor. The fuel supply system for the engine comprises a pump impeller 16 driven from the engine shaft 10 and drawing fuel from a tank along a conduit 18 and delivering it along a conduit 19 past a throttle valve 20 to the engine combustion chamber. The valve 20 comprises a. plugged rotatable valve tube 21 having a series of inlet ports 23 whose area is not changed by rotation and a metering outlet port 24 whose area is controlled by rotation of the cylinder. A minimum flow orifice 23a is provided. The end of the valve tube carries a cylindrical head 25 having a radial nozzle 26 directed towards a receiving inlet 27 in a flange 29 of the valve tube, the fluid from the nozzle returning through ducts 41a, 41b to the duct 18. The pressure induced in inlet 27 acts on a Bourdon tube 30 connected between the flange and the casing to rotate the valve tube to control the aperture of outlet port 24. A steel cup 32 mounted on a spindle 34 has an aperture 33 in its edge through which the jet from the nozzle 26 passes. The spindle 34 which is resiliently restrained by springs 35, 36 carries the eddycurrent coupling member 37 the torque on which depends on the speed and acceleration of the driven member 39. This is achieved by fitting the permanently magnetized member 39 with a spring loaded pivotable shunt 42 whose position alters to vary the flux in accordance with the rate of change of speed of the member 39. In operation, if the engine speed becomes excessive, the increased torque on coupling member 37 turns the spindle 34 and cup 32 displacing slot 33 to reduce the pressuredue to the jet 26 on the Bourdon tube 30. Consequent rotation of the valve tube 20 closes port 24 and reduces the supply of fuel to the engine. Specification 716,255 is referred to.

Filed: 1936-08-27
Abstract: 481,103. Electric signalling systems. CHERRILL, J. Aug. 27, 1936, No. 23539. [Class 40 (i)] [Also in Group XXXVI] Means for indicating the volume of the contents of a tank comprise an oscillatory circuit including a condenser using said contents as a dielectric, the circuit being associated with a source of oscillating electrical energy, means being provided whereby the frequency of the circuit can be tuned from time to time to that of the source, the movement producing this tuning being used for indicating the volume. The condenser 11 is placed in the tank 10 and is connected in an oscillatory circuit containing a variable condenser 12 and an ammeter 13. The said circuit is connected to an oscillatory circuit 14 and the condenser 12 is periodically manually adjusted until the circuits are in resonance, the adjustment indicating the volume of the contents of the tank. The top and bottom plates of the tank may themselves be the condenser plates. In another arrangement, Fig. II, four condensers 21 are connected in parallel to compensate for surges or for tilting of the tank. In a further modification, Fig. III, the condenser plates 31, 32 are situated in a tube 34 within the tank. The liquid enters the tube through apertures 33, holes 38 in a plate 35, and a hole 39. A sudden surge lifts the plate 35 against a shelf 37 and so closes the holes 38. During a sudden fall of level, liquid can leave the tube 34 only slowly through the holes 38. In other modifications the condenser comprises a pair of plates arranged spirally or as concentric cylinders, or consists of parallel plates shaped to compensate for irregularities in the shape of the tank.

Title: Apparatus for turning up the axially outer ends of carcase plies on a tyre building drum
IPC: B29D30/18
Filed: 1964-06-08
Abstract: 1,067,641. Tyre building apparatus. CONTINENTAL GUMMI-WERKE A.G. June 8, 1964 [July 30, 1963], No. 23611/64. Heading B7C. Tyre building apparatus comprises a cylindrical drum 1 upon which carcass plies are located, and a coaxially disposed annular airbag secured at its edges and adapted to turn the axially outer ends of the plies around the tyre bead cores 21, at least one edge 7 of the air-bag being displaceably secured to a ring member 9 axially movable with respect to the tyre building drum. The edge 7 of the air-bag is housed within a radially extending slot 8 in the ring member 9, the second edge of the airbag being clamped to the radially outer periphery of an annular disc 4. The drum 1 and members 4, 9 are mounted on a tube 2 which also carries a bead core positioning device comprising two rings 12, 13 displaceable telescopically relative to each other. The ends of the carcass plies are pushed radially inwards around the drum shoulder by means of grippers 15, 16 which are interconnected by annular rubber bodies 18, 19, respectively. The bead core 21 is then advanced against the carcass plies by means of the rings 12, 13. Initial inflation of the annular chamber formed by the air-bag 5 and the members 4, 9 causes the edge 7 of the air-bag to move radially outwardly in the slot 8. Further inflation causes the member 9 to move away from the disc 4 against the action of a spring 11. The air-bag thus moves radially inwardly of the bead core 21, lifts the extreme end 20<SP>1</SP> of the carcass fabric and finally displaces the ring 13 against the action of a spring 14. The rings 12, 13 may then be completely withdrawn and the air-bag further inflated, the grippers 15, 16 being used as an abutment to force the air-bag and hence the end 20<SP>1</SP> of the carcass fabric against the drum 1.
