Title: Improvements in or relating to a method of controlling and positively driving in either direction a flexible metal or like sheet, and a closing device obtained therefrom
IPC: E06B9/13
Filed: 1961-11-16
Abstract: 988,867. Door operating appliances; shutters. INTERNATIONAL MACGREGOR ORGANIZATION. Nov. 16, 1961 [Dec. 19, 1960; June 22, 1961], No. 41118/61. Headings E1J and E2M. [Also in Division B7] A sliding roof, curtain, door or cover for a building, ship's hold, waggon, truck, or trailer comprising a flexible sheet 1 made of metal or some other resiliently deformable material and adapted to be wound on to, or unwound from, a rotatable drum 2 is characterized in that the winding and unwinding operations are performed solely by means of the thrust exerted on the sheet by the rotation of the drum, this being made possible by employing a drum which is axially grooved or fluted or similarly contoured and by exerting a rolling pressure on the outer turn of the wound sheet in proximity to the generating line at which contact is established between the sheet and the drum, the rolling pressure being applied by one or more freely rotatable members 5 which are placed in pressure contact with the sheet to force the latter to penetrate the hollows on the surface of the drum or on the previous turn of the sheet wound thereon. Preferably the sheet is corrugated and the grooves on the drum match those on the sheet, the members 5 being correspondingly profiled rollers which exert sufficient pressure to produce a simultaneous tensile and flexural elastic deformation of the sheet whereby the angular pitch of the mating corrugations in successive turns of the sheet is maintained constant. Alternatively the members 5 may be circular rollers of elastic material adapted to undergo a temporary elastic deformation to accommodate the corrugations of the sheet. The members 5 are keyed to a shaft 6 freely rotatable in a pair of arms 8 pivotable about a fixed axis 7, and are urged towards the sheet 1 by springs 9 acting on the arms. Alternatively the members 5 may be mounted on pads of resilient material. Adjustable stops 10 limit the movement of the members away from the sheet. The contoured surface of the drum 2 may be formed by permanently securing the first turn of the corrugated sheet 1 to a smooth-surfaced drum, and the drum may be driven by any convenient means, for example a crank 13 and chain 14. Means may be provided to arrest rotation of the drum in the event of the sheet jamming, to prevent permanent damage to the sheet. Slideways 11 in the form of extruded sections 12 guide the sheet to prevent it from buckling, and the crank 13 may be retained in a position corresponding to the unwound state of the sheet by a spring-loaded hook 16. A lock may be provided at the free end of the sheet.

Abstract: 1,163,763. Push-button electric switches; indicators. MAXSON ELECTRONICS CORP. 19 Sept., 1966 [22 Sept., 1965], No. 41726/66. Heading H1N. A switch push-button 24, Fig. 2, which is readily removable from a switch housing 11 has longitudinal stepped slots 52 slidably guided on lugs 55 on the inner wall of the casing 11 the outward movement being normally limited by a step 62 on the groove but on insertion or removal of the push-button 24 it is moved and rotated to spring the grooves 52 apart to permit sloping steps 58 to ride over the lugs 55. An indicator lamp holder 17, 18, Fig. 1, is spring pressed into the centre cylindrical recess 56 of the push-button 24 when removed from the housing and is yieldingly retained by its flange 19 behind inner detents 54 on skirt end 45 of the push-button 24. On reinsertion of the push-button 24 into the housing the centre contact 20 of the lamp holder 18 engages a fixed spring contact 23b and the flange 19 is forced over a detents 43 of a side contact arm 23 so that the lamp holder 18 is locked against endwise movement relative to the housing 11 while permitting the push-button to continue its movement for operation of the switch. Lugs 44, Fig. 3, limit over-travel. The pushbutton 24 actuates a snap-action switch forming the subject of Specification 1,163,764 and comprises a push-bush device with a plunger pawl guide 38 carrying a pivoted pawl 40a which is yieldingly restrained to an axially central position by a coil spring 41 engaging a flat face 37 and which also thereby acts as a return spring for the push-button 24. The pawl 40a alternately engages opposite sides of a pivoted cam 34 mounted on trunnions 51 of a fixed terminal 29 also carrying a pivot pin 35 for one end of a snap-action tension spring 30. The other end of the spring 30 is connected to a movable contact 31, 33 pivoted to the terminal 29 and movable by the spring 30 between fixed contact terminals 28. In a modification the pivot points may be offset so that the assembly is retractive and the contacts are maintained closed only when the push-button is held depressed.

Abstract: 1357585 Toy gramophone YUGEN-KAISHA WATANABE KENKYUSHO 8 Sept 1971 41802/71 Heading G5R In a spring driven toy gramophone in which a stylus is spring urged into contact with the record groove, the stylus pressure is reduced as the stylus moves towards the record centre thereby assisting in maintaining the record speed constant as the spring motor runs down. Spring 34 is wound by a pull on cord 50 and when this is released the spring drives turntable 38 with record 42 via a one way spring clutch 44. Pick-up arm 58 carrying stylus 82 is formed with a pimple 96 which is engaged by an enlarged part 94 of a pressure lever 86 pivotally mounted at its ends 92 in bearing blocks 88. Adjustable blade spring 102 urges lever 86 towards the pick-up with a substantially constant moment and as the pimple moves over path 98 towards the record centre its distance to the pivot axis of the lever increases so that the pressure applied to the stylus decreases as it moves towards the record centre thereby decreasing the load on the spring motor as this runs down. The lever 86 is formed with a notch in a block 127 through which the winding card 50 extends so that as this is pulled the lever is lifted away from the pick-up arm which under the action of spring member 70 is returned to stop 78 with the stylus over the record start groove. Speaker cone 130 is mounted on the end of the pressure lever 86 and a governor is provided to further assist in maintaining the speed of the record constant.

Abstract: 1378228 Cinematography BOLEX INTERNATIONAL SA 12 Sept 1972 42348/72 Heading G2E A cine projector able to receive a stack of reel-to-reel film cassettes includes a film reel drive able to drive the take-up reel of a cassette in a film projecting position, a second film reel drive able to drive the feed reel of a film cassette in a film rewinding position, means for powering both drives simultaneously and a device for transferring cassettes into the projection position, from the projection position to the rewinding position and expelling cassettes from the rewinding position. To implement such a changeover of cassettes a drive shaft (27), Fig.7 (not shown) carries cams (19, 21, 22, 26) which respectively close a film channel after projection is complete, lift a plate carrying the cassettes to disengage the reel drive, move a plate to propel the cassette from the projection to rewinding position and expel the cassette from the rewinding position possibly to a cassette store and move tension rollers into the film paths of the films located in the projection and rewind positions. The changeover is initiated by one of the tension rollers in the projection position sensing increasing film tension when completion of projection is attained. This activates a clutch, Fig. 8 (not shown) which transmits power to the shaft (27). In one rotation of the shaft (27) the cam (26) first withdraws the rollers, the cams (19, 21, 22) changeover the cassettes and the cam (26) tensions the films now in the two positions. This tensioning thus moves the tension sensitive roller to its original position, from which it moved on sensing the increase in film tension just prior to changeover. Hence the tensioning of the rollers de-clutches the drive to the shaft (27) and the changeover is complete.

Abstract: 1326305 Centrifugal pumps N LAING 13 Sept 1971 [11 Sept 1970] 42592/71 Heading F1C [Also in Division H2] In a centrifugal pump comprising an impeller 4, Fig. 3, mounted for universal movement on a bearing 11 and driven by an induction motor comprising a spherical magnetic mass 15 closely surrounded by a thin non-magnetic wall 14, a seal 35 and at least one passage 16 cause an area of the impeller back plate substantially equal in area to that of the impeller eye, to be subjected to pump suction pressure. Thus a relatively high nett axial thrust due to pump pressure differentials across the impeller is prevented, thereby avoiding the tendency of the rotor assembly to lift off the bearing 11 against the action of magnetic axial forces exerted by the motor. The seal is biased against spherical surface of a lip 34 by a corrugated resilient washer 37. The bearing is carried by an extension 30. In an alternative embodiment, Fig. 4 (not shown), the seal is carried by the rotor assembly and bears against the wall 14. In another embodiment, Fig.2 (not shown), the seal is formed by an annular washer-like member (20) concentrically screwed to the top of extension 30 so as to project radially therefrom into closelyspaced relationship with internal surface of mass 15. Fig.1 (not shown), discloses a similar embodiment but the extension and washer-like member are integrally formed with the wall 14.
