Title: Helicopter rotor blade connections
IPC: B64C27/48
Filed: 1969-01-27
Abstract: 1,220,045. Helicopter. UNITED AIRCRAFT CORP. 27 Jan., 1969 [19 March, 1968], No. 4380/69. Heading B7W. A helicopter has its rotor blades 20 mounted on sleeves 34, each of which is arranged about a pitch change axis 32 and carries disc members 82, 84, 86 which intermesh with disc members 110, 112, 114 carried by a spindle 30 to form a stack bearing 40 which is lubricated by a layer of solid plastics lubricant (heavily lined area, for example 152) positioned between the adjacent surfaces of the discs. The discs 82, 84, 86 and 110, 112, 114 on the sleeve and spindle respectively are separated by spacing rings 94, 96, 98 and 140, 142. The spindle and sleeve are spaced by an inboard retainer ring 52 comprising a support ring 54 and a spindle spacer 56 with a solid lubricant therebetween and by an outboard retainer ring 70 comprising concentric inner and outer spacer rings 72 and 74 similarly lubricated, the inboard and outboard retainer rings being of such dimensions that the disc spacing rings 94, 96, 98 and 140, 142 do not contact the opposite discs. The wiper seal 170 is bonded to spindle 30 and bears against sleeve 34 or support ring 52. The lubricant may be a sheet bonded to a disc surface, or a layer of powder.
Patent GB-689721-A (GB)
Title: Improvements in apparatus for transferring webs or fleeces from carding engines
IPC: D01G25/00
Filed: 1951-02-23
Abstract: 689,721. Preparing fibres for spinning. DUESBERG, H. Feb. 23, 1951 [Dec. 5. 1950], No. 4393/51. Classes 120(i), 120(ii) and 120 (iii) Apparatus for the delivery of a web or fleece from a carding engine on to an endless band comprises means by which the apparatus may be stopped, without stopping the carding engine, when a wad of determined length has been formed on the endless band and by which the fleece is prevented from continuing to deposit on the endless band during stoppage of the latter. As shown the fleece of wool or other fibres from the carding machine a passes between "Peralta" (Registered Trade Mark) type rollers c, d to an apron B which delivers it to an endless band A on which it is wound in superposed layers. When the desired length of fleece has been wound into a wad on band A as measured by a meter F an automatic stop motion operates to stop the band, after which the wad is removed by the operator. Shortly before stoppage of band A, meter F causes a warning bell to ring and starts up a fan 52. On stoppage of the band a valve D is operated to connect fan 52 to a funnel 50 whereby the fleece, which continues to be delivered by the carding machine, is sucked up and forced through a conduit 53 into the carding machine loader 54 or any other place. The meter F is driven by a chain 14 from the reversing mechanism H of the drive for band A and comprises a variable speed friction gear adjustable, by rotation of a graduated plate 18, according to the desired length of fleece to be wound on band A. After a disc 22, driven by worm gearing from the meter, has rotated for one revolution, a slide 24 on the end of a rod 25 enters a slot 23 in the disc and rod 25 falls by gravity to drop a pivoted lever 27 between a constantly oscillating lever 43 and a pivoted lever 29, thus causing lever 29 to move so as to disengage a friction clutch connecting a continuously rotary driving shaft 36 to the drive for the endless band A. Movement of lever 29 also acts, through mechanism 61, 65, 66, to operate valve D so that fan 52 is connected to funnel 50 and the fleece is drawn into the latter simultaneously with stoppage of band A. A cam is adjustably positioned on the shaft of disc 22 so as to engage and move a lever 20 a few moments before slide 24 enters slot 23. Movement of lever 20 closes a switch 2 which starts the motor of fan 52 and rings a bell S. To re-start the apparatus a hand lever 70 is pulled. This raises lever 27, permitting lever 29 to move back so that the clutch is re-engaged and valve D is closed again, and raises slide 24 out of slot 23. The apparatus can be stopped during operation by pushing lever 70, shoe 24 being carried yieldably on rod 25 so that the latter can be moved without slide 24 engaging slot 23.

Abstract: 233,656. Ketterer, E. May 9, 1924, [Convention date]. Closed solid-fuel stoves; boilers, arrangement of; grates.-In apparatus for heating hot-houses and hot-beds and supplying carbonic acid gas to plants means are provided for rendering part of the grate of a furnace inoperative so that the heating effect may be diminished as required in the day time without reducing the proportionate yield of carbonic acid. The furnace is arranged below a combustion chamber d extending into a water chamber a provided with a pipe b for the heated water flowing off and a pipe c for the cold water flowing in. The furnace consists of two compartments completely separated by a wall h extending to the filling shaft g. The compartments are provided with inclined grates i, k, firedoors l, m, and ash doors n, o. Beneath the upper part of each grate is a hinged flap s adapted to be turned up against the grate to cut off the air supply to the upper part. It is held in position by a weighted lever. The supply of air to either grate may be cut off by closing the ash door. The combustion gases pass through transverse ducts p into the chimney q and may be led off through a pipe r into a carbonate solution, which takes up the carbonic acid. The grate may be divided into three or more independent parts instead of two. Reference has been directed by the Comptroller to Specification 9154/90.
