Abstract: 893,034. Stapling fibres. GOODYEAR AIRCRAFT CORPORATION. June 27, 1960 [July 8, 1959], No. 22385/60. Class 120(3) Glass fibre and like continuous filaments are cut into short lengths by at least one blade carried by one roll of a pair of cutter rolls between which the filaments pass. Tubular suction means remove the cut fibres at a higher speed than that at which filaments are pulled through the rolls and also separate the fibres. In the apparatus shown, tows or bundles of filaments 10 from bobbins 11 are fed through guides 12 and 13 to the nip between adjustably mounted cutter rolls 2 and 3. Cut fibres 30 are sucked into a throat 14 in a head 15 connected by a flexible conduit 16 to a nozzle discharge head 17 of a spraying apparatus which includes air pressure conduits 18 controlled by valves 19 which create a vacuum in the throat 14. Rolls 2 and 3 are formed of rigid material covered with sleeves 21, 22, of reislient material. The sleeve 22 is tougher and stiffer than sleeve 21 and deforms it when pressed thereagainst so as to grip resiliently the filaments as they are severed by one of several radial blades 25 received in grooves 26 in roll 2 and rockably secured by flexible wires 27. The blades of circumferential rows on the roll 2 are staggered, Fig. 2 (not shown) so that cut fibres from each of parallel filaments are supplied alternately.

Title: Improvements in or relating to gas turbine engine fuel systems
Inventor: FLETCHER ARTHUR HOLMES
IPC: F02C7/22
Filed: 1949-01-14
Abstract: 662,862. Gas turbine plant. ROLLSROYCE, Ltd. March 7, 1950 [Jan. 14, 1949], No. 1154/49. Class 110(iii) [Also in Group XI] In a gas turbine fuel system having a main fuel delivery pipe connected to a pair of injectors through a pair of branch pipes, each branch pipe has a flow constrictor connected to pressure sensitive means so that the load on the latter is proportional to the fuel flow in the branch pipe and the pressure sensitive means is connected to a flow control valve means in one or both branch pipes so as to maintain the relationship between the respective fuel flows. In the arrangement shown fuel is supplied from a tank 17 by an engine driven pump 18 to two reheat burners 16 through a pipe 20 and two branch pipes 22. Each branch pipe contains a flow constrictor in the form of a venturi 23 and the pressures upstream and at the throats of the venturis are transmitted to the opposite sides of a flexible diaphragms 28 through pipes 29, 30. The two diaphragms 28 are connected together through a rod 31 which actuates two valves 24 so that an increase in flow in a branch pipe causes the valve 24 in that pipe to close and the valve in the other pipe to open. In a modification, the two diaphragms are replaced by a single diaphragm which is loaded on one side by the pressure at the throat of one venturi and on the other by the pressure at the throat of the other venturi. This diaphragm is used to control a single valve in one of the branch pipes. In the first arrangement described, the pressure may be taken downstream instead of upstream of the venturi. The diaphragms may be replaced by equivalent piston and cylinder or capsule devices. The arrangement may be extended to control the flow to more than two injectors by allocating one branch pipe as a master control pipe and providing a control means as described for each of the remaining branch pipes. In effect this arrangement comprises a number of pairs of branch pipes of which one pipe of each pair is the master control pipe. The apparatus may be used to control the fuel flows in a selected ratio to each other by selecting fuel flow restrictors having different characteristics in pipes of the same size, by altering the effective areas of the diaphragms or by connecting the diaphragms through a pivoted lever.

Abstract: 346,450. Centrifugal compressers. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London, and ASHLEY, F. W., 64, Eastlands Road, Rugby. Jan. 13, 1930, No. 1187. [Class 110 (i).] Controlling and regulating.-The cross sectional areas of the discharge passages of a centrifugal compresser are varied by means of pivoted diffuser vanes. A movable ring A made in sections is located in a recess between the diaphragm C and the side plate D of the guide vanes G. The ring carries pins B engaging a number of discs E, each of which contains an eccentrically mounted disc F with a slot in which a projection from a vane G is located. The inner ends of the vanes are secured to pivots H. Vanes which pass over the joint J between the ring sections are split and kept in position by blocks K. When the compresser is to run with discharge passages of diminished cross sectional area to prevent surging the blocks K are removed, and the sections of the ring A are moved round in the recess. This rotates the discs E and moves the discs F and the vanes G to a position such as that shown in dotted lines in Fig. 1. The blocks K are then replaced and held by a locking plate.

Abstract: 447,254. Percussive tools. MECOBRENNKRAFT - MASCHINEN GES., and EICHELGRUN, M., 58, Hohenzollernplatz, Frankfort-on-Main, Germany. Jan. 14, 1936, No. 1229. [Class 124] The piston 3 of an internal - combustion rammer is raised by spring supported handles 12, transferring a fuel charge from the space 4, through ports 13, 14 to the combustion chamber below the disc 1. The burnt gases from the previous explosion are drawn into the space 7. Since the diameter of the cylinder 4 is larger than the piston 16 the gases move upward through the gap 8 preventing mixing of the burnt and fresh charges and the charge in the combustion chamber is given an initial pressure. Finally studs 10 seat the valve 9, explosion occurs, raising the cylinder and as the piston 3 descends the gases in the space 7 are exhausted through the port 25. A fresh charge is drawn from the fuel chamber 20 to the space 4. In a modification, the disc 1 is omitted and a valve carried by the handmoved piston closes the port in the diaphragm connecting the combustion and changing cylinders. In this modification, the fresh fuel charge is admitted to the cylinder through a port in the cylinder walls directed in a tangential manner. The force of the blow is adjusted by varying the movement given to the handles 12.

Abstract: 1530391 Driving rollers H A McMASTER & N C NITSCHKE 15 Jan 1976 [19 Feb 1975] 1562/76 Heading B8A [Also in Divisions F4 and C1] The rollers 56, Fig. 4, of a furnace conveyer are located longitudinally by pillars 58 and driven by the lower run 52 of steel belts extending between driven sheaves 38 at the entry end of the furnace and idler sheaves at the exit end. An electric motor 64 drives a gear box 74 through a belt 70, the tension of belt 70 being adjustable by means of a turn buckle 100 which rocks the gear box about shaft 76 which carries sheaves for drive chains 80 engaging the driven sheaves 38 on either side of the roller drive belt 52. A load splitting device (Fig. 13) equalizes the load on the chains driving each sheave 38. The idler sheaves are mounted on uprights 46 pivoted about axis 234, Fig. 10, and moved by hydraulic rams (236, Fig. 1B). Glass sheets from the furnace are carried through a quench and cooling section by rollers 256 located by pillars 258 and driven by chains 250 lying inside the furnace drive belts and running on a support surface (266, Fig. 14). The drive chains 250 run S-fashion round sprockets 310 and 308, Fig. 10, the upper sprockets 308 being driven from a second electric motor in a similar fashion to the belt drive. Sprockets 308 are mounted on the pivoted uprights carrying the belt idler sheaves, and lower sprockets 310 are journalled in plates 298 rotatably mounted on the shafts of the upper sprockets. The idler belt sheaves are coupled to the upper sprockets 308 through a belt 332, so that the action of the electric motor driving the chain 250 moves the idler sheaves to tighten the upper slack run of the furnace drive belt and increase the drive from the driven sheaves. A ram 320 swings the plates 298 about the shafts of the upper sprockets 308 to tension the drive chain 250, without affecting the tension of drive chain 288. The individual rollers of the furnace conveyer are of fused silica, and the supporting surfaces over which their drive belts run are adjustable to ensure proper levelling, (Fig. 5) and the locating pillars which carry guide rollers are adjustable in gangs to ensure proper orientation of the conveyer rollers (Fig. 6). Guide rollers are provided at either end of the belt runs to ensure engagement with the sheaves, (Fig. 7).
