Title: Continuous shelf-storage unit
IPC: B61J3/08
Filed: 1976-06-07
Abstract: 1520182 Warehouses WEELPAL AG 7 June 1976 [6 June 1975 26 Nov 1975] 23428/76 Heading B8W A shelf storage unit comprises longitudinal beams (5) to which rails (6), which are inclined in the longitudinal direction thereof, are attached, Fig. 1 (not shown), so that wheeled carriages 2 carrying goods 1 can roll along the rails due to momentum imparted thereto by a momentum imparting device located in the track defined by the rails (6). The acceleration of the carriages 2 resulting from the incline of the rails is less than deceleration caused by rolling friction between the carriages 2 and the rails (6). The momentum imparting device comprises a push rod 10 disposed between the rails (6), on which rod 10 are rotatably mounted pawls 24 which normally assume an inclined position shown, as shown in the right side of Fig. 5, in which the pawls 24 project above the top of the push rod 10. The latter is connected by an actuating rod 17 to a lever 20 which is rotatably mounted at 21 and which is connected by a further lever 22 to a tripping device 23. When a mobile conveyance (8) having an unloading device (9), Fig. I (not shown), is located at the unloading end of the shelf storage unit (at the right in Fig. 4) to remove the endmost carriage 2 the tapping device 23 is rotated anticlockwise by the mobile conveyance (8) thereby causing movement of the push rod 10 to the left in Fig. 4, against the action of a spring 16, the upwardly projecting pawls 24 being downwardly deflected by traverses 26 provided on the carriages 2 as they pass under the latter. As the conveyance (8), bearing the carriage 2 to be removed, moves away from the shelf unit the push rod 10 returns to its normal position (to the right in Fig. 4) due to the spring 16 and the upwardly projecting pawls, by engaging with the traverses 26, impact momentum to the carriages 2 thereby causing movement of the latter towards the unloading end of the shelf storage unit. In the embodiment described above the pawls 24 are caused to project upwardly by gravity, but in a further embodiment, Figs. 7- 11 (not shown), the push rod (10) is provided with single armed levers (42), each of which is rotatably mounted at (43) on the rod (10) and maintained in its upwardly projecting position by means of a hollow cylindrical body (47) which is deformable to permit downward rotation of the associated lever (42).

Abstract: 643,350. Cutting - machines. INTERNATIONAL CELLUCOTTON PRODUCTS CO. Aug. 27, 1947, No. 23756. Convention date, May 16, 1940. [Class 31 (i)] [Also in Group XV] In a roll of toilet or like paper having a series of transverse weakened lines formed by partially severing the paper, the weakened lines consist of alternate cuts and bonds and are made stronger adjacent the longitudinal centre line of the web than at the side edges thereof in order to facilitate severance of the sheets while enabling the web to be wound into a roll without undesired breakage. This may be effected either by making the bonds in each weakened line progressively narrower or the cuts progressively longer from the longitudinal centre line towards each edge of the web. Alternatively both the lengths of the cuts and the widths of the bonds may be varied. In the example the cuts are formed in a web 12 supplied from a parent roll several times wider than the standard size toilet roll, and the web is subsequently passed through rotary slitter knives 16, 17 to give webs of the required width. The means for forming the transverse cuts comprises an anvil roll 14 provided with channels 22 registering with perforating combs 30 carried by flanges 29 on the rims 28 of spiders or webs 27. 13 and 15 are presser or idler rolls.
