Title: Improvements in or relating to devices for arresting movement of castor wheels
IPC: B60B33/02
Filed: 1980-03-20
Abstract: A device for arresting movement of a castor wheel 5 comprises a locking lever 15 pivotable downwards in the direction indicated by arrow 26, whereby a cam surface 14 on the lever 15 is caused to bear against a reaction surface 24 of a stationary wall portion 8. Upon further downward movement of the locking lever 15, a slider 11 is displaced axially as indicated by arrow 25 whereby a wedge surface 18 on a solid member 20 increases the bias force of a leaf spring 17 until the spring is caused to press against the periphery of the wheel 5 to arrest rotation thereof, and until a disc 3 attached to a fork member 4, 4<1> locating the wheel 5 is arrested by projections 19 so as to prevent pivoting of the fork member. As shown, solid member 20 and projections 19 (on plate 22) are screwed to slider 11; alternatively surface 18 and projections 19 can be pivotally mounted to slider 11; alternatively projections 19 and slider 11 can form an integral unit. <IMAGE>

Title: Apparatus for replenishing the supplies of filter rod sections in the magazines of filter tipping machines
IPC: A24C5/47
Filed: 1981-02-02
Abstract: A combination of production lines for the manufacture of filter cigarettes wherein the filter tipping machines form several groups. The number of groups exceeds by one the number of filter tipping machines in a group. Each filter tipping machine receives filter rod sections from one of two different pneumatic senders by way of one of two discrete pneumatic conveyors. Each sender has a hopper for filter rod sections and several pneumatic propelling units which deliver filter rod sections from the respective hopper into the corresponding pneumatic conveyors. The possibility of feeding filter rod sections to each machine from either one of two discrete senders ensures that the machines need not be shut down in the event of malfunction of a given sender, of one of the two propelling units for a machine or of one of two pneumatic conveyors for a machine. Receiving units which are interposed between the discharge ends of the pneumatic conveyors and the magazines of the respective filter tipping machines convert files of filter rod sections which issue from the pneumatic conveyors into rows and effect forcible admission of filter rod sections into the magazines.

Title: Liquid-projecting monitor
IPC: A62C31/24
Filed: 1981-03-10
Abstract: A liquid-projecting monitor of the spherical head type has its head sealing against a housing which defines together with the head a chamber from which liquid is lead into a passage in the head and then to a nozzle coupled to the head. The head is borne by a horizontal axle for pivotal movement relative to the housing so as to adjust the angular elevation or depression of the nozzle. A center body extends transversely across the interior of the head to enclose the axle and is so shaped, together with the internal surface of the head, that the cross-sectional area of the passage within the head available for liquid flow is maintained at least approximately constant throughout its length, so as to minimize the pressure drop in the liquid flow which passes through the head.
