Title: Improvements in and relating to control mechanism for super-chargers
IPC: F02B37/22
Filed: 1928-01-31
Abstract: 284,609. British Thomson-Houston Co., Ltd., (Assignees of Moss, S. A.). Jan. 31, 1927, [Convention date]. Motor power plant.-Comprises means for controlling the exhaust turbine driving the supercharger of an internal-combustion engine, and relates particularly to aeroplane engines, the controlling devices then acting automatically in accordance with the altitude attained. The impeller 11 of the centrifugal compressor 10 which delivers air through a carburettor 6 to the intake manifold 3 of the internal-combustion engine 1 is driven by an exhaust turbine 13. The turbine nozzles are supplied by partitioned chambers 17, 18, 19 which are connected by ducts 20, 21, 22 with the exhaust manifold 4. The duct 20 has' a branch 23 opening to atmosphere and controlled by a valve 24, and the other ducts are controlled by valves 25, 26. The automatic control gear operates' by closing the valves 24, 25, 26 successively, thus increasing the back pressure in stages, and so increasing the effect of the turbine. On the valve stems are mounted notched discs 27, 28, 29 which are adapted to be engaged by projections 39 on a slide rod 38, and to be held in open or closed positions by springs. The rod 38 is actuated by a piston 40 of a servo-motor 41 having a pilot valve 42 controlling the supply of motive fluid by a pipe 43 connected to the exhaust pipe 4. The pilot valve is moved by a link 44 pivoted at one end to the rod 38 and at the other to a link 45 which is in turn pivoted to a rod 52. This rod is influenced by an adjustable spring 57 and is connected to a vacuum bellows 53 housed in a closed chamber 54 which is maintained at the pressure of the intake manifold 3 by a pipe connection 56. Variation of pressure in the intake due, for instance, to change of altitude, will result in a movement of the rod 52, and a consequent actuation of the valve-gear through the linkage and the servo-motor 41. The floating lever 45 may be adjusted by a hand lever 50.

Title: Extractor device for removing coarse grains from fluidized- bed granulators
IPC: B01J8/00
Filed: 1974-01-23
Abstract: 1455892 Fluidized bed granulator BASF AG 23 Jan 1974 [24 Jan 1973] 03088/74 Heading B5A Continuous removal of particles too large to be fluidized in a fluidized bed granulator 1 through an outlet 10 adjacent the gas distributing plate 2 is facilitated by positioning a deflector plate above the outlet to disrupt the air vortex which tends to form around the outlet and prevents the granules reaching it. A melt, solution or suspension is sprayed in by a nozzle 6 and the fluidizing air from inlet 3 cools the melt or evaporates the carrier liquid to produce granules which when they are large enough pass through the outlet 10 to a shaft 7 where they are removed by a feeder 8. The spent air passes through a dust filter 4 to an outlet 5. The fluidized bed may be circular (Fig. 2, not shown) with a central outlet shaft (12) and a slightly conical gas distributing floor (14). The deflector plate may be flat (17) with a further conical deflecting body attached above it, or may itself be conical with its apex either up or down.

Title: Automatic embroidering machine
IPC: D05C3/04
Filed: 1927-02-04
Abstract: 286,063. Gahlert, F. J., and Bretschneider, M. Feb. 4, 1927. Embroidery machines.-Movements of variable amplitude are imparted to the frame of an embroidery machine from invariable driving movements obtained by the action of a jacquard card 1 on a series of pairs of needle plates 2, 3 carrying jacquard needles 4, 5 by a corresponding series of half the number of levers each comprising a double lever 25, pivoted at 31 at a point dividing its length in the ratio 1 : 3 to a connecting rod 33, and links 17, 18 connecting the ends of the lever 25 to the ends of oppositely directed crank levers 12, 13 pivoted on a common shaft 16 and carrying at their outer ends pins 10, 11 which engage in oppositely inclined slots 6, 7 in the needle plates 2, 3. The four movements in arithmetical progression in either direction which may be communicated to each of the connecting- rods 33 is compounded in known manner and passed on to the embroidery frame by a differential gear having a transmission ratio of 1: 9. The system of levers is returned into the initial position after each stitch by a connecting rod 40 which disconnects and connects toothed slides 35 on the connecting rods 33 with gears 38 on the frame-operating shaft 37. Instead of employing differential gears for compounding the movements of the connecting rods 33, lever systems may be employed. Studs on the needle plates may be engaged by gripper means to relieve the jacquard cards of the pressure of the needle plates when the connecting rods are being moved. Wide loops are formed in the pattern card on either side of the portion which engages the needles on the needle plates, which portion is oscillated to actuate the needles in accordance with the pattern, the unwound portion of the pattern card being guided over the lower portion of a feed roll to a winding up roll by means of counter-pressure rolls.

Title: Improvements in Fuses for Shells or like Projectiles.
Inventor: HAILWOOD ERNEST ARTHUR
IPC: F42C15/24
Filed: 1916-03-08
Abstract: 124,526. Hailwood, E. A. March 8, 1916. Projectile fuses, percussion. Consists mainly in providing a graze pellet with a detent backed by a spring, the detent serving normally to hold in place a tubular distance-piece or stop which, until dislodged during flight, holds the pellet away from the firing-needle. In one construction, the pellet also carries a percussion cap and spring-pressed firing-needle. In the fuse shown in Fig. '1, the pellet G has a spring-pressed detent pin D which passes out into and normally locks a tubular stop C. When the detent recedes on discharge, the part C falls into a chamber B<1>, being moved from the obstructing position by centrifugal force, aided, it may be, by a spring or by contact with a pin N. The pellet may have a passage through it, and may contain a pellet of slow-burning composition to retard the flash produced on impact. In a modification, also having a detent pin and tubular stop similar to the parts D, C, Fig. 1, the .pin extends rearwardly through the pellet and through a transverse wall of the fuse-body, and has a flanged head which normally locks a U- shaped centrifugal stop between itself and the transverse wall. Fig. 2 shows another construction. in which the pellet G<3> contains a spring- actuated firing-pin M, normally restrained by spring-pressed bolts L<3>. On impact, the pellet moves forward to a position in which the bolts L<3> can spring outwardly, thereby releasing the firing-pin and allowing its spring F to thrust it against a percussion-cap D<3>. In the fuses described, the gaine, may be screwed directly on to the fuse-body or to the pellet. The Provisional Specification also describes a construction in which the distance-piece consists of a plate pivoted to the sides of the fuse or graze pellet.

Title: Improvements in variable speed gearing
IPC: F16H63/18
Filed: 1925-02-07
Abstract: 251,700. Munro, H. Feb. 7, 1925. Variable-speed gearing yielding four forward speeds compriess two pairs of meshing toothed gears 17, 18, 21, 22 at one end of the gear box, and two pairs 27, 28, 26, 24 at the other end, with sliding clutches 31, 38 arranged between them on the driving and lay shafts 11, 19 respectively. The lay shaft 19 is supported below the driving- shaft 11 in an unpierced casing 10 which is kept full of lubricating oil up to the bearings of the shaft 11. The shaft 11 is driven by a suitable clutch on a projecting end 13 being operated by a rod 12. The driven element is a sleeve 15 to which the gear 17 is secured and upon which the gear 21 turns loosely. The gears 26, 27 are secured to the shaft 11, and the gears 18, 22 to the shaft 19. The gear 24 is secured to a loose sleeve 25 and the gear 28 is loose on this sleeve. The clutch sleeves are splined on their shafts and each carries two claw clutch members. From the neutral configuration shown in Fig. 1, the lowest speed is effected by sliding the clutch sleeve 38 to the left to engage clutch members 42, 44. The drive passes through the train 11, 26, 24, 25, 38, 19, 18, 17. The next speed is obtained by moving the sleeve 38 to the right to engage clutch members 41, 43. The pair 27, 28 then replaces the pair 26. 24. The third speed is obtained by moving the clutch sleeve 31 to the left to engage clutch members 34, 36. The train 21, 22, 18, 17 then comes into play. The fourth speed is a 1 to 1 drive with the toothed gearing at rest obtained by moving the sleeve 31 to the right to engage clutch members 35, 37. To save space, the two clutch members on each clutch sleeve may be arranged in one plane as shown at 51, Fig. 6. On these two clutch members may be movable inde-. pendently. The sleeves 15, 25 are lubricated by means shown in Fig. 5. In each sleeve inclined apertures 49 are cut which scoop in surrounding oil and force it into a central recess 49'. Tapering these apertures forces the injection. The clutch sleeves 31, 38 are controlled by a sliding cam plate 52, Figs. 3 and 4. Striker forks 33, 40 are flattened when they bear against the vertical plate 52 and have pins 59<a>, 59<b> passing through the cam slots 60, 61. The plate 52 slides in guides 55 and is operated by a lever 64, gudgeon 65, and hand lever 45. Locking of the plate 52 in proper gear positions is effected by a pin 67 pressed by a plate spring 68 anchored at its ends 68<a>, 68<b>. A kick starter 46, 73. 74, Fig. 1, is supported outside the casing 10 without imparing the oil-tight character of the latter.
