Abstract: 436,697. Endless - belt conveyers. NYBORG, T. G., and MINING ENGINEERING CO., Ltd., Meco Works, Worcester. Dec. 5, 1934, No. 34981. [Class 78 (i)] In an endless-belt conveyer wherein the upper run passes over guide rollers 10 and the lower run over guide rollers 27, side plates 2 are detachably connected to the frames of the rollers 10 and are so formed and positioned that their upper portions lie within the frames and adjacent the upper run of the conveyer whilst the lower portions lie outside the frames and well clear of the lower run. The roller frames comprise two U-shaped members 5 set face to face and riveted to a spacing plate 11 and at 6 to the angle irons 3 of the conveyer frame. The rollers are journalled in cut-out portions of the open topped boxes thus formed and pegs 18 secured to the plates 2 are passed into the tops of the boxes. Holes 20 are cut in the outer walls of each box member to prevent accumulation of dust or rubbish in the boxes. The plates are bent outwardly and downwardly at 14 and are cut away and sloped at 16, 17 to fit around the boxes. The lower edges of the plates are received between guides 22, 23 riveted to the angle irons 3 and between guides 24, 25 of which the guides 25 carry the rollers 27.

Abstract: 361,612. C e n t r i f u g a l spinning pots. SVATEK, E., 18, Kempelengasse, Bratislava, Czecho-Slovakia. Nov. 21, 1930, No. 35156. Con vention date, Nov. 21, 1929. [Class 23.] A spinning pot for artificial silk consists of a synthetic resin compound B, Fig. 1, provided with an admixture of loose fibrous material and reinforced with layers A of fibrous matter impregnated with synthetic resin. A rough pattern is made by wrapping a suitable former, as shown in Fig. 2, by winding different tapes simultaneously; the tapes are impregnated with synthetic resin before or after winding. The pattern is then placed in the pressure mould, the required quantity of composition is added, and the pot is completed under the influence of heat and pressure. When forming the pattern, the tapes may be run obliquely to the axis of the pot, and may form two patterns which are subsequently cut apart. In the modification illustrated in Fig. 4, the cylindrical portion of the pot is formed by wrapping with a strip of material ; the ends of the strip are cut to form the bottom and foot portions. The pattern shown in Fig. 4 can be divided to form two pots. In the further modification shown in Fig. 8, the pot is reinforced at heavily stressed parts by the insertion of the pieces A.

Abstract: 970,138. Measuring fluid flow. FERRANTI Ltd. Sept. 12, 1963 [Sept, 15, 1962], No. 35236/62. Heading G1R. In a liquid flow indicator including a first pivotally mounted vane 4 counter-weighted at 8 and second pivotally mounted vane 9 arranged downstream of the vane 4 and counter-weighted at 13, the liquid flow pivots the vane 4 until the flow rate reaches a certain value so as to pivot the vane 4 to such an extent that further increase in the flow rate pivots the vane 9. The flow rate is indicated by a pointer 22 actuated through a magnetic coupling 19, 20 rotated by the vane 4. At minimum flow rate, with the vane 9 in the position shown in Fig. 1, a cam 30, actuated through a magnetic coupling 27, 28, operates a micro-switch 32 in a circuit of an audible or visible alarm device. At maximum flow rate a cam 31 actuates a micro-switch 33 in a circuit to a further audible or visible alarm device.

Title: Improvements in or relating to the extraction of air from steam condensers by multiple stage ejectors having intermediate auxiliary condensers between the stages
IPC: F01B25/00
Filed: 1922-12-28
Abstract: 207,486. Soc. des Condenseurs Delas. Nov. 24, 1922, [Convention date]. Aspirating - apparatus, ejector.-Steamoperated multiple - stage air &c. ejectors, functioning as the air pumps of steam condensers and having auxiliary condensers intermediate between the stages, are provided with a liquid seal collecting chamber for the condensate in the auxiliary condensers, wherein air escapes from the condensate and the condensate can only be returned to the main condenser when a certain level in the auxiliary condenser is reached. The delivery from the preceding stages passes by the aperture B<1>, Fig. 1, into a rectangular box A, where the water collects in a space D until it overflows an edge F of a transverse partition D<1>. Thence the water flows down an inclined plane G in a chamber E<1> divided from a similar chamber E by a longitudinal partition M, and in so doing liberates engaged air that becomes free to rise to the suction passage B<2> of the following stage ejector. Subsequently the water passes through an aperture H in the mid-partition to the other chamber, in which there is a float I adapted, at a suitable height, to open a discharge valve J controlling the orifice K whereby return of condensate to the main condenser may take place. Arrows f show the direction of travel of the water.

A change-speed gear employs electrostatic brakes operable by the Johnsen-Rahbek effect. The degree of engagement of a brake may be varied to vary the speed, or a plurality of brakes may be selectively engaged to introduce various ratios. As shown in Fig. I a two-speed gear has an input sun gear 4 meshing planets 5 on an output carrier 7 which is fast with the ring gear 8 of a second train having a reaction sun 12 stationable by a brake 17 and a carrier 11 fast with the ring 15 of the first train and stationable by a brake 14. Both brakes have semi-conductive carbon layers 18 provided on the train members and in sliding contact with stainless steel brakebands 19. Alternatively the brakes may be of the disc type. Fig. 3 shows a reversing gear having a forward train with an input sun 4, an output carrier 7 and a reaction ring 22 engageable by an electrostatic brake 32 the degree of engagement of which can be varied to vary the slip. Ring 22 is fast with the sun 25 of a reverse train having an output carrier 37 and a reaction ring 28 engageable by an electrostatic brake 32. The voltage applied to either brake can be varied to vary the speed in both forward and reverse. When applied to a vehicle automatic transmission signals representative of engine speed and vehicle speed and a manually variable control signal dependent upon the required torque are fed to control means, and a resultant voltage applied to a brake to vary the ratio. Specification 889,351 is referred to.

Flexible shafts.-In driving gear for screw propellers the intermediate shaft is supported by at least one bearing which has means for damping displacement due to shaft oscillation. The shaft ing may be in sectional lengths with couplings allowing for change of alignment the coupling be ing mounted in the intermediate bearings, and the latter are mounted on longitudinal supports preferably of tubular form. In aeroplane layouts. the engine 1 drives the propeller 2, Fig. 1, through bevel gears and an intermediate shaft 4 which is supported at an intermediate position 10. In ship lay outs, the engine 21, Fig. 3, drives the propeller 22, through spur gears and an intermediate shaft 24 supported at intermediate bearings 30. The shaft is supported in a ball bearing 32, Figs. 6, 7, the outer race being held by a side disc 35 kept up by springs 36 and is also supported by leaf springs 37 in the bearing bracket 34. The latter may be stiffened by a tube 50 running parallel to the shafting, and both the tube and shaft may be enclosed in a stream-line casing 51 when exposed as on aeroplanes. When the shafting is in lengths 40, 40' they have plunger-pot end couplings 41, 41<1> engaging the sleeve portion 42 of the inner ball race. The lengths are stated to be so chosen that the critical speed of the first order is above the maximum working speeds.
