Title: A governor valve assembly
IPC: F02D29/00
Filed: 1967-08-21
Abstract: 1,149,986. Change speed control; valves. FORD MOTOR CO. Ltd. 21 Aug., 1967 [12 Oct., 1966], No. 38425/67. Headings F2D and F2V. A governor for providing a fluid pressure signal responsive to the speed of rotation of a shaft 12 and suitable for controlling ratio establishing clutches and brakes in an automatically controlled motor vehicle change speed gear comprises a casing 96 fast with the shaft 12 and having diametrically opposed radial bores 104, 106 respectively containing a primary governor valve 102 and a secondary feedback valve 100. Pressure liquid is continuously fed from an engine driven pump through ducts 92, 120 to a chamber 116 of the governor valve 102. When the valve 102 is urged outwardly by centrifugal force pressure fluid flows from the chamber 116 to a chamber 118 where it acts on differential lands 110, 112 of the governor valve to balance centrifugal force. The governed pressure in the chamber 118 is supplied through ducts 126, 94 to the governed apparatus and to a chamber 144 of the secondary feedback valve 100. At low speeds a spring 132 holds the valve 100 radially inward to block communication between the chamber 144 and a feedback duct 136 which is vented at 142. When the speed of the shaft 12 exceeds a predetermined value the valve 100 moves outwardly under centrifugal force and the governed pressure is fed back from the chamber 144 through duct 136 to the end of the governor valve 102 which is thus additionally loaded to modify its regulating characteristic. An exhaust port 114 exhausts the chamber 118 when the valve 102 moves radially inward. Fig. 3 (not shown) is a graph of speed against governor pressure.

[Also in Division G6] Fuel elements 20 of a nuclear reactor core 17 within a pressure vessel 10 are transferred between the core and the vessel exterior by one or, as shown, two handling devices operable within cylinders 22 opening into the vessel and closed at their upper ends by removable plugs 27. Each handling device comprises a telescopic mast 26 rotatable and slidable within the cylinder 22 and secured at its lower end to a tubular housing 28. Two guide plates 41 are mounted in side-by-side spaced relationship in the housing 28 and each has two arcuate slots 42, 46 receiving pins 36, 46 on an arcuate arm 38 whereby the arm is guided in the space between the plates. The lower end of the arm 38 is pivotally connected at 49 to a grab 51 whilst the upper end is pivotally connected at the pin 36 to a screwed rod 31 co-operating with a nut 32 driven by a motor 33. The motor is pivotally connected by trunnions 34 to the mast 26 so that when the motor is operated the rod 31 may pivot within the mast as the pin 36 follows the slot 42. The shape of the slots 42, 46 is such that as the upper end of the arm 38 moves downwardly under the action of the rod 31 the lower end of the arm moves downwards only a small amount and most of its displacement is horizontal as shown, for the right-hand device of Fig. 1. To remove a fuel element 20 the entire handling device is lowered to a position a small distance above the core 17 and is rotated in the direction of the element so that the grab 51 can be aligned therewith by operating the motor 33. When this alignment has been achieved the mast 26 is further lowered so that the grab may engage the fuel element, the mast then being raised to remove the element from the core as shown in Fig. 1. The rod 31 is now raised by the motor 33 and the fuel element may be removed through the cylinder 22 after removing the plug 27.

Filed: 1972-08-23
Abstract: 1394886 Differential gear BORG-WARNER CORP 23 Aug 1972 [20 Sept 1971] 39291/72 Heading F2D In a differential suitable for a four-wheel drive vehicle and having an input shaft, two output shafts and a fluid operated friction clutch adapted to couple together two of the shafts, a control device responsive to the speed ratio between two of the shafts is adapted to supply fluid to the clutch to effect coupling when the speed ratio exceeds predetermined limits. As shown, the differential comprises a planet carrier 70, driven by an input shaft 30, a ring 68 secured to the output shaft 53, and a sun 66 on a sleeve shaft 52, which drives the output shaft 50 through gears 54, 56. An hydraulically operated friction clutch 58 acts between the sun 66 and ring 68 (i.e. between shafts 52, 53), and is connectible to a pressure fluid source through passages in the shafts 52, 30 and a normally-closed valve 64. The valve 64 comprises a valve member 116, rotatable on the input shaft 30 and formed with axial passages 118 adapted to connect radial passages 109, 110 in the shaft 30. An annular disc 120 is keyed to the shaft 30 and is formed with openings receiving springs which engage in pockets in the side of valve member 116 to normally position the valve member to disconnect the passages 118 from the passages 109, 110. The valve 64 is controlled by one-way clutches 60, 62 supported on the sleeve portion of a wheel 134 which is connected to the valve member 116 by a spring belt 136. Wheels 140, 142 of clutches 60, 62 are rotated by belts 148, 149 engaging stepped surfaces of the shaft 52, and are so related to the wheel 134 that the wheel 140 rotates 0À88 slower than, and the wheel 142 rotates 1.02 faster than, the wheel 134. In operation, in the case of front or rear wheel spin, one or other of the clutches 60, 62 will engage and, through the wheel 134, cause relative rotation of the valve member 116 and the shaft 30, thereby opening the valve 64 to cause actuation of the clutch 58. In a further embodiment, Fig. 8 (not shown), the valve arrangement 64 is replaced by a positive displacement bidirectional pump which is provided with inner and outer rotors, the inner rotor being keyed to the input shaft, and the pump housing rotating with the shaft 52, the arrangement being such that in the event of loss of traction of a front or rear wheel of the vehicle, relative rotation of the pump elements causes pressure fluid to engage the clutch 58 through a centrifugal control valve.

A worm feed mechanism in operative association with a conveyer 2 to feed upright articles 1 into a labelling or other machine (not shown), comprises a stop 11 to restrain entry of articles 1 on the conveyer to the worm 3 of the feed mechanism, detector means 8 located alongside the conveyer in advance of the stop 11 by a distance representing a predetermined number of articles 1, and retracting means 19 (Fig. 4) for the stop 11 under the control of the detector means 8. A second detector means 9 located in advance of the stop 11 by a distance representing a "buffer" number of articles, also controls the retracting means 19. The detector 9 overrides the detector 8 so long as more than the " buffer " number of articles are immediately in advance of the worm. In operation, under normal flow conditions (Fig. 1) the detector 9 is engaged by the flow of articles and maintains a switch 7 closed. The detector 8 is not engaged and an associated switch 6 is therefore open. When the supply ceases, the switch 7 opens when the last article has passed it. There are then three articles 1 forming the predetermined buffer, and these are held by the stop 11 which moves into position when the switch 7 opens to isolate a solenoid 18. (The conveyer is still running underneath the blocked articles). When the supply recommences, the articles have to back up to the detector 8 since both switches 6 and 7 must be closed before the solenoid 18 can be re-energized (circuit, Fig. 5, not shown). The detector 8 although not deflected under normal flow conditions, is deflected under back-up conditions due to bunching of the articles (Fig. 3, not shown). A manual switch (35) can be used to extend the stop 11 at any time.
