Abstract: 1285194 Making carrier bags WINDMOLLER & HOLSCHER 2 Oct 1969 [28 Oct 1968] 48551/69 Heading A4G [Also in Division B8] Stacking apparatus for a bag-making machine comprises an intermittently operable stacking conveyer for receiving successively delivered bags, the conveyer being provided with a plurality of prongs which have a cross-section conforming to the shape of the handle-holes of the bag, and are disposed at constant spacing, and the conveyer is arranged so that, when stationary, one of the prongs is situated at the stacking station to engage successively delivered bags. The prong may be disposed below the plane of delivery of the bags, and the bags may be deflected so as to drop on to this prong by a vertical stop plate, which is preferably adjustable. As shown, bags are delivered in plane E, and fall on to prong 10. When a sufficient number (measured by time interval or photo-electric eye) have been delivered, the conveyer 1 moves downwards by interval t, bringing the next prong to the stacking station. Prongs 10 are formed as slotted sleeves, and pass over prong 23 on removal conveyer 2. The switch 26, activated by detent 260 stops conveyer 1, and starts conveyer 2. A similar arrangement stops conveyer 2 when the next prong 23 is in position. The stack of bags can then be removed manually from the first prong 23. Conveyer 1 must be of high acceleration, so that the prongs are substituted between delivery of successive bags. Conveyer 2 may be of slower speed, and preferably surrounds conveyer 1. This arrangement may be carried as a unit on wheels, to be attached at the end of a bag-making machine Fig.2a (not shown). The machine may make bags by heatsealing a folded plastics material sheet and attaching or punching handle holes. The bags are preferably given temporary corrugations in the direction of travel by means of a pair of meshing corrugated rollers at the delivery end of the machine to prevent folding.

Title: Control valve assembly
IPC: B60T8/46
Filed: 1972-11-01
Abstract: 1392539 Anti-lock braking systems; valves WAGNER ELECTRIC CORP 1 Nov 1972 [17 Jan 1972] 50372/72 Headings F2F and F2V An anti-lock braking system incorporates a control valve assembly 1 wherein a control fluid pressure applied via a control port 44 to a control chamber 35 acts on a relay piston 25 to operate a self-lapping valve assembly 12, 19, 29, to communicate an inlet port 14 connected to a fluid pressure source to an outlet port 15 connected to vehicle brakes, and wherein two solenoids 43, 43a are energizable to control the control fluid pressure to thereby relieve the braking pressure in the event of a wheel lock-up or vehicle skid condition, the solenoid 43 being energizable first and the second solenoid 43a being energized only if wheel lock up continues, to thereafter the more quickly release the control fluid pressure. As shown in Fig. 1, which illustrates the unactuated condition of the control valve assembly 1 the control port 44 is connected to control chamber 35 via a restricted flow passage B which comprises a passage 68 in a pole-piece 52, an open valve 66, 67, a bore 56 in a sleeve member 55, portions of solenoid chambers 37, 37a above coil retainers 59, 59a and a passage 69: the flow passage B may be restricted by permanent or adjustable flow throttling devices. Thus when a control pressure is applied to control port 44 by operation of an application or foot valve, the control pressure reaches chamber 35 via passage B where it acts to move piston 25 downwardly: this cuts off an outlet chamber 36 from an exhaust passage 22 and connects inlet port 14 to outlet port 15 via the outlet chamber 36 to operate the brakes and a reaction pressure established in chamber 36 will cause the selflapping valve to come to its lapped position. Should lock-up occur a coil 54 is first energized to move armature 61 downwardly against polepiece 52 to close valve 66, 67 to cut off control port 44 from control chamber 35, and simultaneously open an exhaust valve 62, 63 to connect chamber 35 to an exhaust passage 64, which may be restricted. Pressure in chamber 35 is thereby relieved and piston 25 will be moved upwardly to disconnect ports 14, 15 and to connect chamber 36 to exhaust to relieve the braking pressure. If wheel lock-up is not thereby relieved a coil 54a of solenoid 43a is subsequently energized to open a further exhaust valve 62a, 63a to the more quickly relieve pressure in control chamber 35. When the application valve is released pressure in chamber 35 is released via a uni-directional valve 50. In the embodiment of Fig. 2 (not shown) the exhaust passage 64 is omitted.

The lifting arms 5 are secured to a cross member 10 pivoted on a shaft 11 journalled in a fastening 12, and are swung about the shaft 11. The free ends 6 of the lifting arms 5 lie close to the extended centre line of the shaft 11 and have only an insignificant up and down movement, this movement being brought about by the arm 14 connected at one end to a lifting arm, and at the other to an eccentric 17 secured to a drive-shaft 18 of the gearbox 19. The tines 8 are connected to a drive-shaft 22 of the gearbox 19 and are pivotally connected to the fastening 12 by means of a link 23 connecting a mounting sleeve 25 with an arm 26. The fastening 12 is mounted for swinging and sliding movement on a journal 27 fixed relative to the harvester, and as a result the fastening 12 and the associated lifting apparatus can move laterally along the journal and can also swing clear of any solid object on the ground. The mounting sleeve 25 is connected to an eccentric 34 secured to the drive-shaft 22, and thus the tines move up and down together, thereby lifting the beet to the cleaning means 3. When the lifting arms 5 and tines 8 are forced out of position by a beet, arms 39 attached to the fastening 12 will swing in the corresponding direction, flexing a leaf spring 48. After the beet has been lifted the spring tends to urge the lifting arms and tines to their earlier position. Rotating discs 50 fitted with pins 52 aid the transfer of the beets to the cleaning and elevating means, which comprise a number of rotatable rolls 54 having rubber projections 55 fitted with annular beads 56.
