Title: Clutch for transferring the drive from the spinning sprinkler to the basket of a dishwasher
IPC: A47L15/23
Filed: 1969-09-08
Abstract: 1282119 Dishwasher INDUSTRIE A ZANUSSI S pA 8 Sept 1969 [27 Sept 1968] 44376/69 Heading A4F A dishwashing machine comprises a rotatable basket (13), Fig. 1 (not shown) for articles to be washed, a withdrawable frame for supporting the basket 21, 22, a rotatable driving sprinkler 25 for supplying liquid and a clutch mechanism for transferring drive from the sprinkler to the basket which comprises a rotatable intermediate member 17 an arm 20 which rotates with the intermediate member and a pin 24 mounted on the sprinkler to transfer drive to the arm and thence via the intermediate member to the basket, the pin being movable between a first position in which it is disengaged from the arm when the sprinkler is inoperative and a second position in which it engages the arm when the sprinkler is in use, the distance between the axis of rotation of the sprinkler and the pin being shorter than the length of the arm. Basket support 14, which rotates about axis 15, carries a toothed ring 16 in mesh with a gear-wheel 17 mounted on arm 18 biased against toothed ring 16 by spring 19. Spinning sprinkler 25 with nozzles 26 and pin 24 is mounted below the frame. In use, water from the nozzles rotates the sprinkler and extends pin 24 which engages arm 20 to rotate gear-wheel 17 and hence the basket. If the frame is inserted so that sprinkler and gear-wheel 17 are not concentric, pin 24 still engages arm 20 to rotate the gear-wheel. The pin is slidable in a bush 30 on the sprinkler, Fig. 4, so that when water under pressure is admitted to the sprinkler the pin extends to engage the arm. A plain roller or belt drive may replace the gear drive described.

Title: Hydraulic presses
IPC: B30B15/22
Filed: 1971-09-24
Abstract: 1415835 Hydraulic press MANNESMANN-MEER AG 25 Sept 1972 [24 Sept 1971] 44713/71 Heading B5F [Also in Division B3] In an hydraulic press having a row of ram and cylinder assemblies for applying pressure to an elongate workpiece, the pressure in one or more assemblies is controlled in dependence on the extent to which the workpiece extends into the zone over which the assembly(ies) exert force. The press may be constructed as in copending Application 40308/71, having five movable cylinders. To avoid excessive deformation in the case of a workpiece of less than maximum length, each workpiece is fed in the direction of arrow 27 until a sensor 23a detects its trailing edge. The feed is stopped, and the degree of penetration of the leading edge into zone E1 is detected by a sensor 24, which reduces the pressure in the end cylinder, as compared with that in the other cylinders, accordingly. In the case of still shorter workpieces, the trailing edge may be detected by sensors 23b, 23c, or 23d, the corresponding cylinders being off-loaded accordingly.

Title: Smoothing planar workpieces
IPC: B24B39/00
Filed: 1973-09-25
Abstract: 1417930 Rolling mills WILHELM HEGENSCHEIDT GmbH 25 Sept 1973 44820/73 Addition to 1167020 Heading B3M The opposed planar surfaces of a workpiece 3, Fig. 3, e.g. a brake disc, are smoothed by rollers 1 and 2 which are pivotally mounted so that their inclination relative to the surfaces can be adjusted in response to measured deviations of the surfaces from true. The rollers are pivotally mounted (together with backing rolls 4 and 5) about an axis normal to a plane through the roll axes and midway between the roll axes. If the disc surfaces are out of true, Fig. 5, the rollers 50, 51 are so pivoted that their inclinations relative to the surfaces differ, the different roll contact areas then tending to bring the surfaces back to true. The rolls are traversed radially of the surfaces during rolling. Deviations of the workpiece from true are measured by a pneumatic sensor 18 having measurement nozzle 19. An electrical comparison unit 42 then causes an hydraulic control member 20 to suitably supply fluid to one or other side of a piston 28. Movement of the piston from a central position shifts a ball socket 32 and causes a plate carrying the rolls to pivot about its axis in a sense to cause the rolls to correct the workpiece shape.

Abstract: 1485279 Wound drainage apparatus INTERNATIONAL PAPER CO 14 Nov 1974 [19 Nov 1973] 49299/74 Heading A5R [Also in Division F1] A device for the evacuation of fluids from the body comprises: a substantially rigid container 12; an inflatable bladder 40 housed in container 12; a rubber bulb 44 operable to inflate the bladder 40 via a flapper valve 56; a bleed vent 58 in the flapper valve 56 allowing slow deflation of the bladder 40; and an inlet port 26 connectable to a drainage tube. In use, the bladder 40 is first inflated to substantially fill the container 12; slow deflation of the bladder then generates a partial vacuum between the bladder and the interior surface of container 12 drawing fluid through an attached tube and port 26 into container 12. The container has a generally narrow profile, first and second side walls being substantially flat and spaced closer together than third and fourth side walls 20, 22, this arrangement ensuring a substantially constant maximum negative pressure being applicable to the body during deflation of the bladder 40. The bulb 44 is formed having an open neck 40 and an air inlet 46. The bladder 40 is attached to a plug 50 inserted in neck 40 of the bulb, said plug 50 having an air passageway 52 which communicates between the bulb 44 and bladder 40 via valve 56. During inflation of the bladder 40, air inlet 46 is covered by the operator. A second port 30 having a cap 32 is provided for emptying the container. A valve 80 may be provided to prevent backflow of liquid out of port 26. The port 30 may extend into container 12 as shown at 31 to limit the inflation of the bladder; port 26 may similarly be extended. The container may be emptied through port 30 either by pouring, or by evacuation, by connection of port 30 to a vacuum pump. To prevent blockage of fluid from the port during evacuation, a recess 63 in the walls may be provided, and the interior walls of the container 12 may be roughened or coated with silicone, and the outside of the bladder may be treated with chlorine. In a second embodiment, Fig. 8 (not shown), a bulb is provided with an air inlet having a flapper valve with a bleed vent, thus eliminating the requirement to cover the air inlet during inflation. In a further embodiment the bulb is supple and of a volume sufficient to fully inflate the bladder and has no air inlet thus forming a closed system, whereby a single compression of the bulb is required to inflate the bladder.
