Abstract: 1337289 Trimming moulded articles HOOVER BALL & BEARING CO 28 May 1971 [28 May 1970] 18129/71 Heading B5A [Also in Division B8] Blow moulded articles 14, Fig. 7, each having a head or neck from which a grooved flash portion 22, 24 extends are trimmed by severing the said extension by a knife 132 while the article is supported and rotated by groove engaging means 120, 122. As the split mould 12, Fig. 3, opens the moulded articles are directed via a two position guide into sleeve members 52 carried by chains the driven sprocket of which is driven by an hydraulic motor via a one-way clutch so that the sleeve members 52, Fig. 1 are moved between the loading station 42 and the discharge station 48, the articles moving along platforms 41, 144. The hydraulic circuit is such that the hydraulic motor decelerates at the end of its stroke. At the trimming station the groove 24 of each article is engaged by a rotary guide 120 and a stationary guide 122 and is raised from the platform 41 which is vertically adjustable. The drive of the rotary guide 120 is taken off the chain drive, the guide being knurled to effect rotation of the article against the knife 132. The trimmed articles come to rest on the platform 144 which is intermittently raised and lowered on guide rods by a rotary hydraulic actuator 148, Fig. 3. When the platform 144 is in its lower position a pusher 160, operated by a rotary hydraulic actuator 164, via a cam and cam follower mechanism, pushes the articles from the platform 144 on to the conveyer 162. The pusher 160 is given a smooth accelerating- decelerating movement so that the articles are moved smoothly on to the conveyer 162.

Abstract: 254,525. Wortley, R. S., and Sprague Meter Co., Ltd. July 20, 1925. Gas, supplying by meter; coin action, mechanical-connection and multiple-coin.-In order to adapt prepayment mechanism for gas meters for use with coins of different values, the crown or coin wheel is mado axially adjustable to accommodate coins of different diameters, and a pinion driven from the meter recording mechanism is made axially adjustable to effect the required alteration in gear ratio for coin value. The crown wheel a, Fig. 1, which is actuated by the coin is fixed on the end of a shaft b rotatable and slidable in a bearing c at one end and in a lug or lugs e at the other. The position of the shaft b, according to the diameter of the coin, is determined by a collar i secured to the shaft by a set screw j and located between the lugs e as shown or abutting against the front face of a single lug. By releasing the collar the position of the shaft can be adjusted. Adjustment for coin valve is effected by moving axially a pinion l secured by a set screw to a sleeve m free to rotate but not to slide on the shaft b. The sleeve m is threaded internally to engage a slidable but non-rotatable threaded valve-actuating sleeve n. When pennies, say, are used the pinion l is driven directly by a worm o fixed to the shaft r of the meter recording mechanism. When shillings are used the pinion l is moved axially to engage a worm p of reduction gearing, the pinion l now being driven by the worm o through a pinion t, skew pinions w, v and the worm p. The reduction gearing is mounted in a bracket u so as to be detachable as a unit. The pinion l may be moved out of gear with both worms o, p when it is desired to use the meter as an ordinary meter.

Title: Improvements in or relating to machine for finishing irregular shaped articles
IPC: B24B21/00
Filed: 1944-09-27
Abstract: 586,490. Grinding propeller blades. UNITED AIRCRAFT CORPORATION. Sept. 27, 1944, No. 18468. Convention date, Oct. 26, 1943. [Class 60] A machine for finishing irregular shaped articles, e.g. propeller blades, comprises a contact roll for applying a belt having an external abrasive surface to a piece of work on a work support, said roll having a peripheral depression therein constituting an impression of a surface of the finished work piece, means for effecting relative movement of said roll and said work piece longitudinally of the latter, and means for rotating said roll about its axis in timed relation with said longitudinal movement. The abrasive belt 42 runs over driven pulley 43 and idler 40, a pulley 52 being spring- pressed to take up slack. A contact roll 56 is mounted in a bracket 64 vertically adjustable, by worm wheel 88, on head bracket member 74 pivoted to the frame of the machine at 75 and having a stop to engage stop-member 84a on the frame ; arms 77 on head bracket 74 carry rollers 80. The propeller blade 108 is supported by members 104 on a cradle 98 which is mounted for rocking, about the longitudinal axis of the blade, on carriage 36 which is reciprocated by fluid pressure cylinder 37. Laterally extending arms 116 on the cradle carry rails 118 and 120 which engage the rollers 80 carried by head bracket member 74. The rails are so shaped having regard to the pitch of the blade that as the carriage reciprocates the rocking of the cradle maintains the surface of the blade which is being finished substantially horizontal. A portion of roll 56 has a peripheral groove 132 of constantly varying contour, corresponding to the variation in contour of the camber side of the blade along the length thereof, the remainder of the roll being plain. When treating the camber side the roll is given a peripheral speed equal to that of the carriage by means of a rack 140 on the carriage engaging a pinion coupled to the roll. For treating the reverse side of the blade the pinion is uncoupled from the roll, which thus rotates rapidly and acts as an ungrooved roll. A freely rotating rubber belt 158 supported on rollers' 159, 160, 161 and 162 is interposed between the roll and the abrasive belt.

Title: Improvements in means for controlling the speed of eddy current clutches
IPC: H02K49/04
Filed: 1942-12-30
Abstract: 562,509. Electro - magnetic clutches. HEENAN & FROUDE, Ltd., and WALKER, G. H. Dec. 30, 1942, No. 18479. [Class 35] To minimise changes in relative speed of shafts 2, 4 connected together by an eddy current clutch comprising a primary member 1 and a secondary member 3, the excitation of the field coil 5 is controlled in accordance with the slip between the two members in such a manner that when the secondary member is running at a speed lower than the primary member the excitation and torque of the clutch increases with a fall in speed of the secondary member, but when the secondary member runs at a speed higher than that of the primary member, the excitation and torque increase with a rise in secondary speed. As shown in Fig. 1, the field coil 5 is excited by a generator 15 driven through gearing 14 from the cage 12 of a differential gear, the sun-wheels 8, 9 of which are geared to the shafts 2, 4 respectively. A reversing gear 11 is interposed in the drive between the shaft 4 and the sun-wheel 9. The speed of the generator 15 is therefore proportional to the slip speed of the clutch. Slip rings 6 on the shaft 2 and connected with the coil 5 are supplied by the generator 15 through a rheostat or other regulator. In a modified arrangement particularly applicable to the combination of the driven shaft 4 with an alternator connected to a supply line and running at a substantially constant speed, the sun-wheel 8 is driven by a small synchronous motor instead of from the shaft 2. In another arrangement the exciting generator comprises two concentric elements, one of which is driven directly, or through gearing, at a speed proportional to that of the primary member, the other element being similarly driven at a speed proportional to that of the secondary member, so that the output of the machine is proportional to the slip between the two members. Fig. 2 shows such an arrangement wherein the generator is incorporated in the clutch, one element 17 of the generator being carried by the primary member and the other element 16 by the secondary member. Specifications 547,987 and 519,159, [both in Group XXXVII], and 576,620 are referred to.

Abstract: 762,902. Combustion apparatus. BABCOCK & WILCOX, Ltd. June 24, 1954 [June 26, 1953], No. 18522/54. Class 51 (1). [Also in Group XIII] A forced flow, once-through steam &c. boiler, especially for operation at super-critical pressures, comprises three independently operable cyclone furnaces 10, of the form described in Specification 552,747, arranged to discharge high temperature gases into a secondary furnace 11 whence the gases flow through a slag screen 12 into a vertical radiation and gasmixing chamber 13 and discharge therefrom through a lateral pass 14 in which is disposed a secondary superheater 16, the rear portion of pass 14 being divided into parallel passes 14a, 14b locating respectively a convection primary superheater 17 and high and low pressure reheaters 18, 19, the gas flow through each pass being controlled by dampers 130, 131. From passes 14a, 14b the gases flow into a common outlet duct 20 leading to an air heater 21 and an induced draft fan 22. Combustion air is supplied to the furnaces by a fan 24 which delivers the air through duct 25, the air heater and ducts 28. A regulated portion of the cooled flue gases is withdrawn from duct 20 through a conduit 29 leading to a fan 30 from which it passes through duct 31 and ports 122, 124 into chamber 13 at sufficient velocity to ensure intimate mixing with the fresh gas and in sufficient quantity to ensure that the temperature of the mixed gases at the entrance to pass 14 is such that entrained slag particles are in a solidified condition and that overheating of superheater 16 is avoided. Feed water at a pressure, for example, of 5500 pounds per sq. in., is supplied to the inlet header of the cooling tubes of one of the end cyclone furnaces and passes successively through these cooling tubes and those of the other two furnaces to an outlet header whence the heated water is conveyed to the inlet header 68 of the primary superheater 17, the furnace heating surfaces being so arranged that the transition zone occurs in this superheater. Steam from the superheater 17 passes via headers 69, 70 into a radiant superheater consisting of serially connected tube panels lining the walls of chamber 13, the final superheating of the steam being effected in the secondary superheater 16. The final steam temperature is controlled primarily by controlling the firing rate of the cyclone furnaces 10, further control suitable for operation at partial loads to raise the steam temperature being provided by varying the number of furnaces in use and by regulating the quantity of recirculated gas. Specifications 201,304, [Class 51 (i), 206,559, [Class 122 (iii)], 398,413, [Group XIII], and 762,940 also are referred to.
