Title: Improvements in or relating to fluid pressure operated actuators
Inventor: MILLARD DENNIS JOHN
IPC: F15B15/26
Filed: 1962-01-19
Abstract: 922,808. Hydraulic apparatus. BOULTON PAUL AIRCRAFT Ltd. Jan. 19, 1962, No. 2094/62. Addition to 899,514. Class 69 (2). The actuator of the parent Specification which has a piston 1 and cylinder 20 provided with locking means consisting of an inner member 5 having projections 3 which are engageable with complementary recesses 2 in an outer member 23 when the inner member is moved against a bias upon reduction of fluid pressure in a chamber connected to an inlet 32, is modified by the provision of a chamber 24 adapted to be connected to a sump, and an intermediate chamber 26 communicating with the fluid pressure chamber through a passage 10 presenting a high impedance to fluid flow and with the sump chamber except when the actuator is in the unlocked condition. The inner member 5 is secured to a partition 15 which separates the sump chamber from the intermediate chamber and has bores receiving axially-slidable rods connected to a ring 27 which, when moved to the left by a spring 7 upon interruption of fluid pressure to the inlet 32, displaces a piston 11 connected by a rod 25 to a tapered plug 6 to the left to expand the inner member 5 so that the projections 3 engage the outer member. In operation, when fluid pressure is initially supplied to the inlet 32, the fluid pressure acts to move a piston 8 to the right which, in turn, moves the piston 11 into engagement with the partition 15 so that the plug 6 is extended from the inner member to permit the projections 3 to be withdrawn from the recesses in the outer member and the communication between the passages 13, 34 is closed to prevent flow of fluid between the intermediate and sump chambers 24, 26. The fluid passing through the high impedance passage 10 can thus build up the pressure in the intermediate chamber 26 and as the pressure equalizes across the passage, the piston 8 is returned to its left-hand position by a spring 12. If the supply of pressure fluid to the inlet 32 is interrupted, the fluid in chamber 26 flows through the passage 10 to the inlet 32 and the drop in pressure in chamber 26 permits the spring 7 to move piston 11 away from the partitions and establish communication between chamber 26 and the sump chamber 24 through passages 13, 34, whereby the consequent rapid drop in pressure in chamber 26 enables the spring 7 to rapidly move the piston 11 and plug 6 to the left, the movement of the plug expanding the inner member 5 to engage the projection 3 with the outer member 23 and the recesses 2 when coincident therewith to prevent movement between the piston 1 and cylinder 20.

Title: Control apparatus for an elevator car
IPC: B66B1/16
Filed: 1971-01-19
Abstract: 1315589 Automatic speed control HITACHI Ltd 19 Jan 1971 [21 Jan 1970 2 March 1970] 2650/71 Heading G3R [Also in Division H2] Control apparatus for a lift comprises high speed and low speed motor systems involving three phase motors HM and LM respectively. The high speed motor is used for accelerating the lift from rest up to a constant travel speed in three steps, each step comprising shorting out three of the resistors Rs using relay contacts. The low speed motor car be switched to either the three phase inputs U.V.W. for normal operation to a rectifier circuit VR which supplies a DC voltage for braking the motor so as to decelerate the lift, the magnitude of the braking current being controlled by the difference on speed between a speed pattern and the actual speed of the lift as determined by a tachogenerator TG. The speed pattern, Fig.3C, is produced by the superimposition of the output of a pattern generator PG, producing a smooth curve by integrating the pulses produced by a series of relays, one associated with each flow, which are deenergized as the lift passes, and the output of an auxiliary pattern generator which produces an impulse waveform. The braking system is inoperative until the lift passes a deceleration starting point at which time the high speed motor is cut off and the low speed motor connected to the rectifier circuit VR. The purpose of the impulse part of the speed pattern is to ensure that when the braking circuit is connected, the pattern speed exceeds the lift speed so that no sudden braking force is applied, the decay on the impulse causing a gradual drop of the pattern speed below the lift speed and hence a smooth onset of braking. When the lift has been slowed to a low speed an electromagentic brake MB is operated to bring the lift to a standstill. In a further embodiment the speed pattern may suddenly be reduced to zero at a time prior to the lift stopping so as to increase the braking during the very low speed period of operation of the motor. The two motors may be replaced by a single multiple motor connected so as to be operable with either 4 poles or 16 poles, to affect high speed and low speed operation respectively, the DC voltage being applied to the 16 pole arrangement to effect braking. Safety cut outs are provided to operate the electromagnetic brake should the lift approach the top or bottom of the duct. Also the high speed motor cuts out if the lift speed exceeds a predetermined limit.

Title: ?in supporting mechanism for automatic yarn winders
IPC: B65H67/02
Filed: 1951-02-02
Abstract: 684,812. Supply holders for yarn winding machines. FOSTER MACHINE CO. Feb. 2, 1951 [April 11, 1950]. No. 2706/51. Class 120 (ii). A winding machine bobbin support having a rotatable member arranged for intermittent rotation and provided with bobbin supporting pins pivotally mounted upon it has cam means co-operating with the bobbin supports in succession for pivotally moving a bobbin support and for positively moving a bobbin off its support. The invention is described as applied to the winding machine disclosed in Specification 598,596. The rotatable member 112 includes a disc 114 rigidly connected to a sprocket gear 210 through a sleeve 116 rotatable on a stationary shaft 74 fixed to the machine frame through a bracket 75. When a supply bobbin is exhausted, or the yarn has broken between the supply and take-up packages, a rack 203, (Fig. 3), on a tender that advances past the winding unit rotates the gear 210 and the disc 114, upon which bobbin supporting pins 79, mounted in brackets 118, are pivoted about pins 122. Each pin 122 has a coil spring 124 coiled around it with its ends bearing against the disc 114 and a bracket 118, so that pins 79 are normally held upright. Replenishment bobbins are guided on to the pin 79 in replenishment position by a chute 230 formed in two hinged parts arranged to open as the pin 79 is moved into the supply position. In the replenishment position the bobbin rests on a ledge 136, but as the pin 79 moves to supply position, the bobbin rides off the ledge 136 allowing the bobbin to drop on to and be securely engaged by the tapered upper end of the bracket 118. As the replenishment bobbin moves to supply position, the bracket 118 supporting the empty bobbin is moved into contact with a cam 140, which tilts it and, as the disc 114 continues to rotate, engages the bottom end of the bobbin core 70, so that it is pushed off its pin 79.

Abstract: 737,117. Sparking plugs. JET IGNITION CO., Inc. Jan. 30, 1953 [Jan. 31, 1952], No. 2709/53. Class 7(4). In a sparking plug comprising a body 11, Fig. 1, containing an ignition chamber 13 open at one end, a pair of electrodes 20, 15c having opposed convex faces axially arranged within the chamber to provide a spark gap, and an electrode head, comprising, for example, a disc 15a, a baffle plate 15b and the earth electrode 15c, closing the chamber 13 and providing one or more passages such as ports 17 in the disc 15a opening into helical channels between the helical baffles on the plate 15b, arranged to cause gas to swirl about the axis of the electrodes and to draw a spark laterally away from the axis, the portion of each channel opening into the chamber is arranged out of line with the associated port 17. Between the lower part of the insulator 10 and the adjacent portion of the body 11 is formed an annular clearance 12 which leads into the cylindrical chamber 13. The electrode 15c which differs in size from the centre electrode 20 is forced into the central opening of the disc 15a and so locates the baffle plate 15b over a stem 15d projecting from the disc 15a ; the latter is then forced into an enlarged bore 16 in the lower end of the body 11. The ports 17 are inclined and have a smaller cross-section than the helical channels. After assembly the disc 15a and plate 15b are copper brazed together. In a modification, the chamber 13, Fig. 4, communicates with the exterior by tangentially disposed bores 26 in the disc 25 which approximate to the turns of a helix each of which open into one of a number of inclined ports 27 of smaller cross-section than the bores 26 ; the ports 27 are extended to comprise pockets 28 which retard the entrance of burnt gases into the chamber 13. In a further modification, the earth electrode of Fig. 1 has a small bore connecting the ignition chamber directly with the engine cylinder. In a final modification, the earth electrode of Fig. 4 has an axial and a joining radial bore that connects the spark gap with the inner end of the ignition chamber.

Abstract: 839,062. Voltage measurement. COLLINS RADIO CO. Jan. 28, 1958 [April 8, 1957], No. 2854/58. Class 37. In an arrangement for analysing variations in the amplitude of a signal which may be the A.V.C. voltage of a radio receiver being used for a field strength survey, either an indication of the amplitude exceeded by the signal for a predetermined percentage of the time or the percentage of time that the signal exceeds a preselected amplitude, or both is continuously generated. The signal which is applied to a terminal 58, Fig. 2, of a chopper 11 vibrated at 400 cycles per sec. and a reference voltage applied at terminal 59 produce, when they differ, a square wave output which is amplified and applied over a transformer 33 to a comparator comprising valves 13a, 13b wherein the phase relative to a 400-cycle supply synchronous with that driving chopper 11 is detected to energize coil 35 or 36 of a relay 14 according to whether the input voltage is above or below the reference. Voltages applied to the contacts 37, 38 of the relay for pick-up by the tongue are preselected by potentiometer 15 and are of such a ratio to give a required charge/discharge ratio to condenser 42, Fig. 3, of the integrator circuit to which the relay output is applied, whereby a voltage sufficient to actuate relays 20, 21 in later stages, is developed only if the percentage of time which the signal exceeds the reference varies from the percentage set by the potentiometer 15, for which a graph is to be traced. The relays 20, 21 are actuated through a further chopper 17 and phase detector 19 energized from a 60-cycle supply, and drive a bi-directional slipping switch 22 in one direction or the other respectively, to change the reference voltage from a potentiometer 23 to a new value whereat the percentage of time it is exceeded corresponds to that required.
