Abstract: 620,621. Drying peat. SOC. ANON. FORNI ED IMPIANTI INDUSTRIALI INGG. DE BARTOLOMEIS. Jan. 23, 1947, No. 2163. Convention date, Feb. 3, 1941. [Class 34(ii)] Material such as peat is dried in conduit 7 before entering a furnace 1 by hot gases from the furnace mixed with recirculated dryer gases and vapours in a mixing chamber 13. Combustion gases from the furnace 1 are circulated via a conduit 16 to the mixer 13 and are there mixed with gases and vapours from the dryer 3 which are circulated by a fan 12 between the mixing chamber and the dryer via conduits 11 and 14. A portion of the dryer gases are permitted to escape via outlet 18 controlled by a valve 19. In traversing the dryer 3 the mixture of furnace gases and returned dryer gases traverses the conduit 7 twice via louvred openings as indicated by the arrow in the figure. The material hopper 2 may be closed by a baffle 5 and the entry of the dried material into the furnace may be regulated by a valve 6. Valves 15, 17 and 19 may all be operated independently or automatically to maintain the desired temperature of drying gas circulating through the dryer 3. Headers 20, 21, 22 are provided for multiple operation of more than one furnace and dryer.

Filed: 1925-11-17
Abstract: 266,393. Dawson, Sir A. T., and Buckham, Sir G. T. Nov. 17, 1925. Endless - trackvehicles.-Relates to motor road vehicles of the kind having endless - tracks and wheels for alternative use, the endlesstracks being driven, when required, through clutches which are disconnected when the vehicle is in the wheeled condition, and comprises means for automatically applying brakes appertaining to the endless-tracks to prevent creeping of the tracks when they are not in use. In the construction shown, the track frames C<2> and the road wheels B are carried by arms E and springs Bx pivoted to the chassis A, so that by rocking the arms E the wheels are lowered to the ground and the tracks raised therefrom, and vice versa. When the vehicle is in the wheeled state. friction or epicyclic clutches, through which the tracks can be driven, are disconnected. Brakes F<7> are provided on the track driving-wheels C<1>, and can be applied simultaneously by means of a hand lever F<4>, a slotted rod f<4>, bell-crank levers F<5>, slotted links f<5>, and arms F<6> operating the brake cams f<7>. When the arms E are rotated to convert the vehicle from endless-track to the wheeled state the brake blocks F', cam f', and arms F<6> rotate with the arms E, and finally raise the links f<5> and rotate the bell-crank levers F<5>. Stops f‹ limit the movement of the bell-crank levers, and further movement of the arms E then causes the brake arms F‹ to turn on their pivots and apply the brakes lightly so as to prevent creeping of the tracks. Specifications 265,688 and 266,052 are referred to.

Abstract: 667,001. Chucks and sockets. ARNOLD, J. C. (Benjamin, M. L.). Jan. 30, 1950, No. 2400/50. Class 83 (iii). A tool or work-holder comprises a housing 1, at least three members 6, 10, 15 universally jointed to the housing and transversely movable relatively to each other, an elastic member 21 disposed adjacent the member 15, and a clamping nut 25 adjustable relatively to the housing for applying pressure to the member 21 so as to clamp the members 6, 10, 15 resiliently in adjusted angular and lateral position relatively to the housing. The housing 1 has an enlarged head 3 provided therein with a conical seating 4 and pegs 5 to engage diametrically-opposite recesses 9 and a spherical surface 7 respectively, formed in the seating member 6. The latter member is connected loosely by means of further slots 9 therein to the member 10 which is provided with thrust balls 11 and projections 14 adapted to loosely-engage slots 17 formed in a flange 16 on the member 15. A ring 20 is interposed between the flange 16 and the member 21 which is formed of rubber or the like so that, with the parts in adjusted position, the member 21 can be caused by the nut 25 to deform and transmit a substantially even pressure around the line of contact between the surface 7 and seating 4, the frictional resistance along the line of contact being sufficient to prevent the member 21 from regaining its original form and returning the tool R into parallel relationship with the housing 1. A collet 22 to grip the tool R is inserted in the member 15 and caused to operate by means of a nut 28, a ring 27 and inclined surfaces 18 and 19 formed in the bore of the member 15. Modifications of the invention comprise the provision on the housing 1 of a projecting part adapted to bear within a recess in the member 6, the direct bearing of the member 21 on the member 10, the provision of one or two rings 20 with or without annular flanges for engaging the bore of the member 21 and the replacement of the member 15 by a flanged sleeve adapted to grip the tool by means of screws or by a flanged sleeve formed with a morse-tapered bore to grip the tool. In the latter case, the sleeve extends into the bore of the housing 1 which is provided with a slot to receive the drift adapted to eject the tool from the tapered bore. Specification 583,959 is referred to.

In a rigid or resiliently flexible coupling or universal joint disposed between two at least approximately coaxial shaft ends 1, 2 and comprising bosses 4, 5 mounted on the shaft ends and connected together by power transmitting means, each of said bosses comprises two axially separated portions 6, 7 clamped together by bolts 12 and thereby connected to the corresponding shaft end, 1, by way of conical rings 15, 16, the boss portion 6 supporting said power transmitting means and the boss portion 7 providing an additional power transmission path between the shaft 1 and the boss portion 6. In the rigid coupling shown, the thickness of the boss portions 6, 7, 9, 10 is such that they can be individually inserted through the gap 3 between the shaft ends 1, 2 thereby eliminating the need for displacement of the shaft ends during coupling installation or removal. The conical rings 15, 16 preferably have at least one cut to assist fitting. The boss portions 6, 9 are spaced by a ring 21 and connected together by bolts 22. In Fig. 2 (not shown), the poss portions 6, 9 are connected by resilient rubber, or rubberclad steel, pins arranged radially outwardly of the boss portions 7, 10 to permit assembly without shaft displacement. In Fig. 3 (not shown), the boss portions 6, 9 are connected by a cross (33) to form a Hooke's joint. The boss portions 6, 9 have alternating axially extending claws embracing the arms of the cross via intermediate layers (34) comprising e.g., elastic material such as rubber and retained by closure members bolted to the cross arm ends. The layers (34) permit small radial shaft misalignment. In Figs. 6, 7 (not shown) the power transmitting means between the boss portions 6, 9 comprises an annular, parallelly or helically corrugated, flexible, single or multi-walled tube radially clamped either between the boss portions on each shaft end, the boss portion 6 being desirably radially cut into sections and retained together by a spring ring, or between the boss portion 6 and a conical ring further to and contacting the corresponding conical ring 15 and desirably radially cut into sections and retained together by a spring ring. This construction permits axial, radial and angular misalignment.

In a bay for rack-mounting communication equipment, connection between a mounted trough 15 of apparatus and the rack verticals 7 is made by U-links 14, which on the equipment side engage in sockets 16 in the end cans of each trough. Wiring from the socket to components in the end can is direct and wiring to other cans may be by cable form or in the case of adjacent cans by cross-strapping parallel tag strips. Troughs carrying various types of carrier current equipment are shown and to facilitate standardization variable components, e.g. channel filters 47, Fig. 14, are made to be plugged by a plug and socket arrangement 46-48 into a standard channel assembly can such as 34, Fig. 11. To facilitate access to relays for adjustment purposes a hole 38, Fig. 8, covered by a plate 39 is provided in the back of the trough and the relay mounting is made to swing out on a hinge or to slide out on rails. The cable form to the relays is pleated to allow for withdrawal. Lamps and other large items previously often mounted on the front of the equipment and in consequence necessitating deep dust covers are housed within the trough and a shallow dust cover the outside surface of which may only be flush with the U-links is provided.
