The conveyer 10 is controlled by an infrared beam sensor 14 which activates the conveyer 10 when a part 1 is absent from the delivery end of the conveyer track 12 and deactivates the conveyer 10 when a part 1 is present there as detected by interruption of beam 17. A supply feeder sensor 21 is positioned so that its beam 25 is angled across the receiving position of the conveyer 10 which acts as a master controlling the feeder 20 as a slave according to the following method. When absence of parts 1 is sensed by the supply sensor 21 the feeder 20 is activated. When a blockage is sensed by sensor 21 a time delay of one or two seconds is set off so that a few parts 1 may pass the beam 25 before the feeder 20 is deactivated. If parts 1 are absent then the feeder 20 is immediately reactivated while if parts 1 are present the feeder 20 remains inactive until the supply beam 25 is again unbroken.

Abstract: 1421783 Automatic ventilator H G EAST & CO Ltd 26 Oct 1973 [4 Nov 1972] 50916/72 Heading A5T An automatic ventilator includes a gas input line 10, at least one flexible expandable container 15 or 16 communicating with said input line, a constraint 17 limiting the expansion of said container, a gas output line 13 and a pressure responsive valve 12 interconnecting said lines and responsive to the gas pressures in the lines to open to pass gas to the output line 13 and to close to permit exhalation &c by a patient. A valve device 26 is provided in the output line 13 to pass gas to an inspiration port 27 and from an expiration port 28 to atmosphere and to avoid inspiratory and expiratory flow in a common line. The device also has a vent port 29 open to atmosphere. The gas input line 10 is connected to the output line 13 via the pressure responsive valve 12 and a filter 11. The pressure responsive valve 12 operates to remain closed while the line 13 vents to atmosphere until the pressure in the input line 10 reaches a specified value and remains open until the pressures in the input and output lines 10 and 13 are substantially equal. The specified pressure at which the valve opens is adjustable by means of collar 25. The inspiration port 27 is coupled to the output line 13 through a one way valve 30 which permits flow from 13 to 27. A diaphragm valve 31 uses the pressure in the output line 13 to control communication between the expiration port 28 and the vent port 29, closing across the expiration port when the pressure in the line 13 increases upon opening of the pressure responsive valve. The ventilator is both pressure and volume limited, the pressure limit being set by adjustment of the pressure responsive valve 12 and the volume limit being set by the volume of the bag 15, the minimum volume that the ventilator can deliver per cycle. In an alternative embodiment, two expansible containers are provided, the second also having a constraint 17 and communicating with the input line 10 through a flow control valve 20. In this case the volume of bag 16 at the moment of opening of valve 12 is included in the volume limit.

The baler has a frame unit 36 fixed at one side of the baler frame 16 and comprises a pair of parallel side channels 38, 40 extending forwardly at an angle to the frame 16 from a frame extension 18. The draft tongue 50 extends through a horizontal arcuate slot defined at the front of the frame unit 36 between arcuate crossmembers 42 and 44, and is pivotally connected at 52 to a cross-piece 54 of the frame unit. The draft angle between the tongue 50 and the frame unit 36 is controlled by a double acting hydraulic ram 58 connected between the frame unit at 62 and a pair of gusset plates 64 on the tongue 50. A removable stop 66 limits the lateral movement of the tongue and a pin 70 can be located in a hole in cross member 44 to fix the position of the tongue. Drive to the baler from the PTO @  of the tractor is via shafts 74, 76, universal joints 78, 80, 82, a slip clutch 84, gear box 86, chain and sprocket drive 90, and a power input shaft 92.

The armature of a linear induction motor is located between motor windings fixed relative to plates forming capacitors on either side of the armature to control the frequency of supply to the motor windings so that the gaps on either side of the armature are maintained substantially equal. As described, the coils of a linear induction motor are mounted on a railway carriage and arranged to be on each side of a fixed rail forming the armature. Plates mounted on the carriage on either side of the rail form capacities with the rail and variations respectively control the frequencies of the supplies to the coils so that they are maintained at substantially equal distances on either side of the armature during travel. Speed of travel is controlled by varying the magnitudes of the polyphase A.C. or pulsed voltages applied to the coils. The supply may be generated on the carriage or fed to it by rail or overhead cable. Application to arrangements in which the coils are stationary and the armature is the moving wire rope of a hoist or metal strip being treated is referred to.
