Title: Improvements in or relating to means for obtaining textile fibres from cane plants
IPC: D01B1/22
Filed: 1954-10-18
Abstract: 756,656. Decorticating-machines. HANS, R. J. (Florida Industrial Laboratory, Inc.). Oct. 18, 1954, No. 29920/54. Class 120 (1). In a decorticator for obtaining bast fibres from cane plants by means of at least two stroking rollers rotating in opposite directions and having intermeshing. fins, in combination with an arcuate backing plate surface concentric with the first of the rollers and closely spaced from the fins thereof, the fins of the first roller have sharp edges whereas those of the subsequent roller or rollers have dull or rounded edges. As shown, Fig. 1, stalks 15 are fed by feed rollers 11a, 11b, 11c, 11d over a deflecting plate 19 to a pair of stroking rollers 12a, 12b. Roller 11a is peripherally V-grooved while rollers 11b, 11c and 11d are soft-surfaced and comprise a hard core 16, a layer 17 of sponge rubber and a jacket 18 of abrasion-resistant rubber. Plate 19 has surfaces 19a, 19b and 19c, the latter being concentric with roller 12a; the tubular fibre layer is split and stripped from its woody core on changing direction at the junction between surfaces 19b and 19c. Roller 12a has sharp-edged fins 20a and roller 12b has rounded fins 20b. Fins 20a, 20b intersect to a depth substantially less than their height, which is not greater than their spacing around the rollers. The peripheral speed of rollers 12a, 12b is approximately three times the feeding speed of rollers 11a-11d, so as to exert traction on the fibres and remove adherent trash therefrom. A high-speed conveyer 23 ejects loose trash and hurls the trailing end of each fibre, as it leaves rollers 12a, 12b, over a collecting bar 24. The whole mechanism is mounted on wheels 45a, 45b so that it can be used in the field. An alternative stripping mechanism, using an inverted stripping plate 119 and three stroking rollers 112a, 112b and 112c, is shown in Fig. 5; roller 112a has sharp-edged fins while rollers 112b and 112c have rounded fins.

Filed: 1946-10-10
Abstract: 617,827. Hydro-mechanical variable-speed gearing. FORD MOTOR CO., Ltd. Oct. 10, 1946, No. 30250. Convention date, Nov. 3, 1945. [Class 80 (ii)] In a variable-speed gear of the kind in which the transition from first to second speed and from second to third speed takes place automatically by the operation of clutches actuated by fluid under pressure supplied by a pump, the pressure in the pump and therefore, the torque capacity of the clutches is controlled by a relief valve progressively operable at a lower or higher pump pressure as the transmission torque decreases or increases. As shown, applied to a motor vehicle hydromechanical variable-speed gear of the kind described in Specification 615,175, stepped planets 24 ... 26, Fig. 1, mesh respectively a sun 27 connected to a clutch carrier 19, a sun 28 on an intermediate shaft 13, and a driven sun 29. In first speed, the sun 28 is driven through a hydraulic coupling 16, 17 and a one-way clutch 18. In second speed, a hydraulically-operated clutch 21 is engaged to byepass the coupling and drive the sun 27, the clutch 18 overrunning. A one-way brake 32 prevents reverse rotation of the planet carrier 22 in both these speeds. For third speed, which is direct drive, a hydraulically-operated clutch 23 between the members 19, 22 is additionally engaged to lock up the gearing. Pressure fluid for the clutches 21, 23 is supplied by a pump 33 through conduits 37, 38 and is controlled by a valve 41 regulated by a centrifugal governor 42 on the member 19. A spring-loaded relief valve 46, Fig. 2, connects the pressure and intake chambers 36, 35 of the pump 33. Pressure fluid, via a bore 52, acts on the right-hand end of the valve member 46 to move it to the left and connect the chambers 36, 35 when a predetermined operative pressure is attained. To vary this operative pressure in accordance with the torque requirements of the clutches 21, 23 at any particular time, the left-hand end of the valve member 46 coacts with a bellows 65 to which engine inlet manifold suction is admitted via a pipe 73 so as to modify the action of the valve spring 62.

Title: Flexible corrugated tubes
IPC: F16L9/06
Filed: 1973-06-26
Abstract: 1431222 Making corrugated tubes E SIEGWART 26 June 1973 [17 July 1972] 30263/73 Headings B3A and B3E [Also in Division F2] A flexible corrugated tube is made by helically coiling a thin metal strip 1 formed with longitudinally extending corrugations, the corrugations having the shape shown in Fig. 2, the borders of successive convolutions overlapping one another with at least one corrugation in the overlapping border portion of a convolution fitting into a corrugation of the overlapped border portion of an adjoining convolution, the corrugations then being radially compressed so that they become interlocked and assume a dove-tailed shape as shown in Fig. 3. Preferably the convolutions are overlapped by half the width of the strip 1 as shown in Fig. 2. The tube is made by winding the corrugated strip 1 on to a rotatable mandrel 2 (Fig. 5) with the aid of pressure rollers 3, 4, 5 which are formed with grooves (not shown) for receiving the corrugations. The roller 3 is arranged so that one half of it engages the oncoming strip 1 whilst the other half engages a previously wound convolution. The grooves in the half of the roller 3 which engages the oncoming strip 1 have a depth which is at least as great as the unreduced height of the corrugations whereas the grooves in the other half of roller 3 are shallower than the corrugations so that the corrugations are compressed to the dove-tail shape shown in Fig. 3. These latter grooves are also wider than uncompressed corrugations (i.e. at least of a width b). The rollers 3, 4, 5 may be formed from an elastomeric material. In a modification (not shown) the rollers 3, 4, 5 have no grooves but are each provided with a radial step half way along its length so that one half allows free passage of the oncoming strip 1 whereas the other half compresses the corrugations on the previously wound convolution of the strip 1. The tube may also incorporate a sealing tape 7 which is bonded to the edges of the overlapped portions as shown in Fig. 3, or may incorporate a sealing strip (not shown) of plastics material or adhesive coated paper which is wound between the overlapping convolutions. The plastic sealing strip may be heated to fuse or bond it to the overlapping convolutions.

Torque-measuring apparatus for interposition between a rotatable spindle 2 and a machine extension member 1 providing a reaction torque, to balance that of the spindle comprises a sleeve 7 secured to the extension 1 and to a casing 11 housing a friction disc clutch for coupling the spindle 2 to a driving member 33 integral with a flexible strut 19 with one 17 held between two balls (20), (21), Fig. 2 (not shown) in the casing 11 and the other end 18 in contact with the feeler 29 of a comparator gauge (30). In use on a screwing machine whose spindle 2 is driven by a compressed air turbine, the sleeve 7 is secured to the extension 1 and an adaptor 5 in the screwing ferrule 4 couples the spindle 2 to a spindle 6 to which clutch discs 38 are splined. With the turbine in operation a button 59 is turned to rotate a screw 56 in the casing 11 and so push upwards a plunger 51 supporting a tail-shaft 47 integral with the strut 19 to compress friction discs 40 between discs 35 splined to the driving member 33 and the discs 38, thus coupling the spindle 6 to the bar 19. The torque load on the turbine is balanced by the reaction torque of the casing 11 measured by deforming the strut 19. The strut is precalibrated so that a measurement of the torque can be derived from the reading of the comparator and the turbine adjusted until a desired reading is obtained.
