Filed: 1976-04-20
Abstract: 1481946 Debranching apparatus DEERE & CO 20 April 1976 [21 April 1975] 15881/76 Heading B5L A tree harvesting machine comprises a mobile base carrying a delimber assembly 30, a feed unit 40 for pulling a tree through the delimber assembly and a boom assembly 46 for handling a tree and presenting it to the delimber assembly and feed unit, the delimber assembly having open and closed states controlled by a delimber actuator, for respectively receiving a tree and encircling the tree so as to effect delimbing thereof as it is pulled through the delimber assembly, the feed unit having open and closed states, controlled by a feed unit actuator, for respectively receiving a tree and engaging the tree for pulling it through the delimber assembly when drive is imparted to the feed unit, and a control system responsive to a start signal to provide a sequence of control signals with predetermined delays therebetween and to apply these signals to the said actuators and the feed unit to initiate the closed states of the delimber assembly and feed unit and drive of the feed unit, the control system being responsive to a reset signal to initiate the open states of the delimber assembly and feed unit and terminate the drive of the feed unit. The control system may be switched to manual control and in the automatic mode may be switched so that the feed rolls 42 close first i.e. before the jaws 34 of the delimber, or vice versa. The use of an automatic control system is stated to allow the felling of a further tree by means of the felling device 48 while the previously felled tree is in process of being debranched, thus improving the cost effectiveness of the machine.

Abstract: 1381657 Filters for pneumatic conveyors A ZIMMERMANN 6 April 1972 [24 April 1971 (2)] 15987/72 Heading BIT In an installation wherein particulate material is conveyed through pipeline 1 from bin 5 to filters 3 by a stream of air drawn in at position 7 by a blower 4, a hose switch 15 is provided so that at selected times, the hose section 22 (Fig. 2) is disconnected from the suction union 16 of the blower and is connected to the delivery union 17 by means of actuator 26 which displaces the flange 24 in rail 25. The material which accumulates on filters 3 falls into chamber 10 and is removed by bucket-wheel valve 11. In the operating position shown in Fig. 3, the blower 4 draws air from the environment in the direction of arrows 29 and forces the air into the conveyor creating therein a slight positive pressure which is sufficient to discharge particulate material from chamber 10. To clean the filters 13, a conduit 12 and magnetic valve are provided by means of which a counter pressure is applied against the filters from a pressurevessel 13.

Abstract: 497,067. Scraping retort &c. walls. PUENING, F. June 9, 1937, No. 16033. [Class 51 (ii)] [Also in Group XXVIII] A blade for scraping the metal wall of a coking- chamber is held in contact with the wall by magnetic attraction, the blade preferably forming the core of an electromagnet which may be automatically deenergized when the blade is lifted out of the coking chamber. In an apparatus for use with narrow vertical retorts 13, 14, Fig. 1, a row of ten scrapers, of which only one, 24, is shown, is carried by a vertically sliding beam 36 mounted on a motor-driven travelling framework 25, which also carries a coal hopper 30 and compacting screws as described in Specification 497,066. Each scraper is suspended from a pair of tubes 42 passing through guides in the beam 43, and can be turned through 180‹ to allow both sides of a retort to be scraped by gearing 50 actuated from a crank 44 through a bevel pinion 47 slidable on a squared shaft 46. The scrapers are guided into the retorts by inclined surfaces 18, and where the scrapers operate in grooves or flutings in the walls the magnetic part of the scraping-edge may be flanked by non-magnetic portions. Additional pressure of the scrapers on the walls may be obtained by bowing the scraper rods, or by screws 62, Fig. 6 acting on the upper ends 63 of scraper rods pivoted at 61. Auxiliary magnets may be provided between the scrapers and the pivot points. The arrangement shown, in Fig. 6 allows the two sides of a heating-wall to be scraped simultaneously.

Class 120(2) Thread winding mechanism comprises a driving drum 15, a swingable forked member 1 for applying a bobbin 13 to the drum 15 and maintaining tlhe bobbin 13 in contact with it along a generator, and an abutment 18 for limiting movement of the swingable forked member 1 in the downward direction, and two rotatable rollers 8 mounted on the inner side of each arm of the forked member to co-operate with the edges of the bobbin 13, the axes of rotation of the rollers 8 on each arm being situated at different distances from the axis 2 about which the forked member 1 swings, and the rollers 8 on one arm being axially aligned with the rollers on the other arm of the forked member 1. Springs 20 or counterweights act to maintain the unloaded member 1 away from the driving drum 15, but the weight of an empty bobbin 13 brings it into driving contact with the drum 15. When doffing a full bobbin 13, it can rest out of contact with the drum 15 on one pair of rollers 8 and a pair of resilient pins 14 in the arms of the member 1. Instead of the pins 14, spring-urged balls may be employed. In a second embodiment, the rollers 8 in the member 1 rest on top of the bobbin 13 and the springs 20 act to urge the bobbin against the drum 15. Resilient pins are provided on abutments at the end of the arms of the member 1, and a notch provided in one arm to assist in removing a completed bobbin 13 from driving contact with the drum 15 to rest on the pins.
