Abstract: 1,230,082. Fluid digital counters. INSTRUMENTS & MOVEMENTS Ltd. 18 March, 1968 [15 March, 1967], No. 12200/67. Heading G4P. A digital fluidic counter comprises a series of fluid pressure operated valves, each having an inlet port 36, first 38 and second 40 outlet ports, and first 46 and second 48 control ports, the valves being arranged in two chains 16, 18 receiving pulses alternately on respective lines 54, 56, and having output ports 1 . . . 6 indicating the state of the counter. As described, input pulses arrive as puffs of air 20 directed on to a vane 21, each puff displacing a biased detector valve 10 into a position in which pressure fluid from a source 26 is applied to line 50 (primary pulse), and when valve 10 is biased back to its initial position pressure is transferred (secondary pulse) to line 52. Valves 32 and 34 (described as a distributer), receiving primary and secondary pulses respectively, are cross-connected so that e.g. a pulse from outlet 38 of valve 32 not only supplies line 54 but, via control port 46, shifts valve 34 so that the next secondary pulse will move valve 32 to supply the next primary pulse to line 56. Operation. Assuming that the last output pulse appeared at port 6 after passing from line 56 via valve 62, then, at the same time, a pulse was transmitted to control port 48 of valve 58 to position the latter for directing the next pulse on line 54 via outlet 40 and 36, 40 of valve 60 to output port 1. Again, pressure at output port 1 is also transmitted to control port 48 of valve 62, setting the latter to direct the next pulse on line 56 via 36, 40 of valve 62 and 36, 40 of valve 64 to outlet port 2. This output pulse also prepares valve 60 for subsequent output at port 3, and so on. Resetting of the counter may be done manually, and other forms of valves giving equivalent results may be employed.

Abstract: 1,232,017. Packaging. J. HANDLEY. 25 Oct., 1968 [25 Aug., 1967], No. 39335/67. Heading B8C. An article packing machine automatically erects cardboard boxes from blanks, fills the boxes with layers of articles, and delivers the boxes, the blanks being held during folding and filling by suction. Biscuits are conveyed at 92 in two ranks to gates 93, 94. Suction cups 97, 98 and 136, 137 are carried by vertically moving suction tubes 99, 110 and 138, 139 and horizontally moving suction tubes 140, 141, 142, 143, the cups 136, 137 being interleaved with 97, 98 to hold the box alternatively. Cams 111, 112 lift the suction pads to engage the bottom blank in stack 95, 96, it is then drawn down through a folding die, not shown, then cams 122, 123 move vertical racks 124-127 and pinions 128- 131 which swing arms 132-135 to fold over side flaps into the box so that locking projections engage in slots in the box. The suction cups 97, 98 then drop the box on to cups 136, 137, the vacuum being switched from one set of cups to the other to effect transfer of the box. Frames 138, 139 are then moved horizontally by cams 144, 145 to the filling position, shown, under the gates 93, 94. A cam on the main shaft 113 now raises one of the gates and the front rank of biscuits is thrust into the box. Then the same thing happens to place the second rank of biscuits in the box. The gate closes, and the box is transferred back to conveyer 150 to delivery. Cups 136, 137 are then restored to their initial position. Micro-switches 160, 161 may be used to ensure that the biscuit ranks are full. (For Figure see next page.)

Abstract: 1,232,052. Electromagnetic clutches or electromagnetic disc brakes. STEARNS ELECTRIC CORP. 21 Aug., 1968 [12 Sept., 1967], No. 40048/68. Headings F2C and F2E. A self-adjusting clutch or brake includes means for limiting the range of movement of an armature 14, Fig. 1, mounted on a rotor 24, to or from an electromagnet 6 comprising locking plates 30 mounted on posts 28 projecting from the armature or rotor and spring means 34 acting on an end of the plate to releasably lock the plates to the posts and to urge the armature away from the electromagnet and stop means for limiting the movement of the other plate and when the range of armature movement becomes excessive thereby releasing the lock between the posts and the plates to permit movement of the plates on the posts to compensate for wear. The fixed electromagnet 8 is energized to attract the armature 14 which slides on splines 22. The annular spring 34 normally maintains plates 30 at an angle which locks them to posts 28 so that the spring biases the armature away from the magnets by acting on the end of the plates 30 at their outer ends, the reaction of the springs being absorbed by stops 42. When the movement is excessive the inner ends of the plates 30 engage the stops 42 through the spring 34 and the plates are thereby tilted into a plane normal to the posts 28 allowing the plates to move relative to the posts to take up a new datum position which maintains the desired gap between the friction surfaces. In a modification the annular spring is replaced by individual plate springs (340), Fig. 3 (not shown). In another embodiment a spring 342, Fig. 5, is arranged between an arm 60 secured to the armature and the plate 300. When the armature is retracted a stop finger 64 engages the plate end 380 to limit the movement. When the armature movement becomes excessive the elbow 60 engages the plate which is thereby unlocked and moved to a new datum position.

In a continuous film movement motion picture projector the output from a photo-electric frame position sensing arrangement is used, after comparison with a reference to operate a trigger circuit controlling the shutter. The position of a frame reference aperture 29, Fig. 1, in a film 23 is monitored by light from a source 11 falling on a photo-potentiometer 31, pivoted mirror 17 in the beam path being rotated by a servo galvanometer 37 to maintain the monitoring beam on the photopotentiometer and as a result keeping stationary the projected frame picture which is reflected by the same mirror. The cutting off of the beam when an aperture moves clear of a gate slot 25 produces a large signal from the comparator to operate solenoid 61 through the reset and timing circuits thus introducing after a predetermined time interval an additional intermediate shutter operation to reduce flicker.

Abstract: 1,264,827. Reciprocating pumps or motors. INTEGRAL Ltd. June 29, 1970 [June 30, 1969], No.32949/69. Heading F1A. In a swash-plate pump or motor, the radial components of the reaction forces produced by the pistons are reacted by a hydrostatic bearing within an extension 39 of the rotary cylinder block 14, the bearing being symmetrically disposed relative to the centre of convergence P of the radial components. The bearing is formed by a recess 40 between extension 39 and a stationary member 22, liquid under pressure from the high pressure side of the pump or motor being supplied to the recess 40 via filter 35, passage 21 and restriction 23. Liquid from recess 40 passes to casing outlet 13 via bearing 24 and passage 25. A vented sleeve is rotatably mounted on the cylinder block to reduce churning of the liquid in the casing. The swash-plate 19 is supported by part-circular, hydrostatically-balanced bearings 28 formed between the swash-plate and the casing 10 and supplied with liquid from passage 21 via passage 32. A servopiston 37 responsive to output pressure acts against spring 36 to control swash-plate 19. A nutating plate 17 is supported by a spherical surface on extension 39.
