Title: An improved method of regulating steam operated prime movers for driving wood grinding machines
IPC: G05D13/00
Filed: 1926-03-08
Abstract: 248,780. Akt.-Ges. Brown, Boveri, et Cie. March 9, 1925, [Convention date]. Rasping-apparatus. - In plant comprising a boiler steam-driven wood-grinding machine, and one. or more engines or turbines consuming a variable quantity of steam, a steady supply of steam from the boiler is maintained without blowing-off by varying the load on the wood-grinder to suit the available. quantity of steam. The prime mover driving the wood-grinder may be a turbine having variable 'amounts of steam tapped therefrom; or it may be fed from a boiler which supplies also a back-pressure or mixed-pressure turbine of varying steam consumption. In an electric generator installation a wood-grinder may be connected to the network to take up the available balance of power, with steady steam generation in the. boiler. Stoking is regulated according to the pressure indicated in the turbine or the wood-grinder, in order to limit the output of steam from the boiler. The load on the grinder f, Fig. 2, may be varied by pressure-applying means g subjected to oil pressure controlled by a regulator i on the diaphragm of which the boiler pressure acts through a pipe k. In a modification, Fig. 3, the regulator i controls the inlet valve m of the prime mover driving the grinder, a speed-regulator n reducing the effective oilpressure on the maximum permissible output being passed.

Title: Improvements relating to pipe lines for high pressure high temperature fluid
Inventor: BAILEY RICHARD WILLIAM
IPC: F16L13/02
Filed: 1951-03-19
Abstract: 734,341. Pipe joints. METROPOLITANVICKERS ELECTRICAL CO., Ltd. April 17, 1952 [March 19, 1951], No. 6536/51. Class 99 (1). [Also in Group XXII] In a pipe-line for conveying fluid at very high temperatures and pressures, comprising straight lengths of wrought metal piping joined by short bends or other junction pieces welded between the straight lengths by circumferential butt welds, the wall thickness of the straight lengths is determined in accordance with the temperature and pressure of the fluid to be piped without additions to allow for the reduced strength of the welds or for thinning by bending, while at least in the vicinity of each weld between a junction piece and a straight length the wall of the former is thicker than that of the latter so as to exert a supporting influence on the weld such that the circumferential stress therein is not greater than the product of the weld factor, i.e. the ratio of weld strength to pipe strength, and the general circumferential stress in the straight lengths. In Fig. 1, a cast bend 3 welded at 1a, 2a, to straight lengths 1, 2, has thickened wall portions 3a forming supports for the welds. In Fig. 1A (not shown) the weld conforms with a taper at the end of the bend. A backing ring 32, Fig. 6, may be used to register the pipes before welding and forms a base for the groove to receive the welding metal ; the backing ring may be flush with the inside of the pipe, or, instead of using a separate ring, an extension of one pipe may spigot into the other pipe. Where extra support is required to allow for inefficiency of welds made on site, increased wall thickness is provided on both sides of the weld which may then be of reduced thickness. As shown in Fig. 6, a collar 29 of greater thickness than that of the pipes is shop welded at 28 to a pipe 27, and is site welded at 31 to a second pipe 30. In Fig. 8 a collar 43 is shop welded to a pipe 41 and is site welded to a collar 42 shop welded to a pipe 40. The collars are held together, for site welding, by flange rings 45, 46 clamped against shoulders on the collars by bolts 47, 48. To facilitate removal, the rings are split diametrically and bolted together.

Title: Aircraft cabin pressure regulating means
IPC: B64D13/02
Filed: 1945-03-19
Abstract: 593,585. Fluid-pressure servomotorcontrol systems ; valves. BENDIX AVIATION CORPORATION. March 19, 1945, No. 6908. Convention date, Feb. 26, 1944. [Class 135] An aircraft cabin pressure control comprises valve means regulating the escape of air from the cabin and a cabin pressure-responsive device for operating the valve means, the latter including a valve seat and a hollow cylindrical obturating member open at opposite ends anl longitudinally movable to the closed position where one end of the cylinder engages the valve seat. In an embodiment, the valve consists of an axially movable cylinder 21 which is closed when its lower edge engages the valve seat 10. The valve slides on a fixed cylinder with a nozzle head 19, and it carries a piston 22 subject on its lower face to the pressure in the cabin and on its upper face to a loading spring 23 and the pressure in a chamber 27. Chamber 27 communicates with a chamber 29 through a bleed 44, the latter chamber being in communication with the outside atmosphere. Air under pressure is supplied to the cabin by a supercharger &c. and it can pass through a screen 34 into a chamber where it acts on a spring-loaded evacuated bellows 35. From sea level up to a first predetermined altitude, bellows 35 will not have expanded sufficiently to contact and open a spring-loaded valve 38 so that the pressure in chamber 27 will be just above that of the outside atmosphere and valve 21 will be maintained in a partially open position to give a slight differential of cabin pressure above that of the outside atmosphere. From the first up to the second predetermined altitude, the pressure acting on bellows 35 will allow the latter to expand and open valve 38 to increase the pressure in chamber 27 and valve 21 will tend to close to maintain the cabin pressure constant. When the second predetermined altitude is reached, valve 38 will be fully open and thereafter remains so, and a second spring-loaded bellows 46, of which the interior is subject to cabin pressure through a screen 48, will contact and start to open a valve 57 byepassing the bleed port 44. This will give a constant pressure differential control of valve 21. The datum values of the two controls are adjusted by altering the position of bellows 35 by rotating screw 37 and by varying the lost motion between the lower end of bellows 46 and the adjusting screw 55A of valve 57. In a modification giving a constant pressure ratio control above the second predetermined altitude, loading spring 53 is replaced by a further bellows surrounding bellows 46, the space between the two bellows being evacuated. A manual control of valve 21 is provided by longitudinally moving a shaft 64 which is first rotated so that spring fingers 68 thereon engage a flange 69 on the valve. The shaft is held in adjusted position by spring fingers forced on to the shaft by a nut 73. A set-screw engages a longitudinal groove 74 in the shaft or a horizontal groove in either of the extreme positions. Specification 521,623 is referred to.

Title: Improvements relating to braking mechanism of the internally expanding brake shoe type
IPC: F16D65/14
Filed: 1935-03-06
Abstract: 453,153. Internally-expanding brakes. KERSHAW, A. G., and WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., 82, York Road, King's Cross, London. March 6, 1935, No. 7040. [Class 103 (i)] Actuating mechanism for internally-expanding brakes comprises a substantially cylindrical member rotatable about its axis which is substantially tangential to the brake drum, balls or rollers being disposed in inclined recesses between the end faces of this member and those of thrust members which engage the ends of the shoes. Automatic slack adjusting means for the shoes may be provided within the drum. The outer ends of a pair of thrust members 10, Fig. 2, non-rotatably slidable in a casing 11 fixed within the brake drum, engage each a shoe end. An operating member 15 rotatable about the axis of the members 10 by means of pivots 16 extending into the members 10, has attached to it by a pin 19 a pair of discs 17 each formed with arcuate recesses 18 each of increasing depth from end to end. Balls 20 are disposed between these recesses and corresponding recesses in the members 10. The member 15 has an arm 21 to which is attached a link 24 by which the member can be turned, thus forcing the thrust members 10 apart by the cam action of the balls and recesses. To compensate for wear of the shoes, the effective length of the right-hand member 10 is automatically adjustable and for this purpose comprises an intermediate part 27 screwing into an end part 25 and having a ring of ratchet teeth 30 engaged by a locking ratchet ring 31 connected to the part 10 to prevent rotation. The teeth 30 are also engaged by teeth on an annular member 32 splined to the pivot 16 of the operating member 15. When rotation of the member 15 in applying the brake is excessive, the ratchet member 32 slips a tooth and during the release movement turns the member 27, thus extending the thrust member 10, 25 as a whole. The thrust members are urged towards each other by a spring 36 bearing on a plug 35 in the member 25 and on a rod secured to the left hand member 10. In a modification, Fig. 6, the rotatable operating member comprises two parts slidable in but non-rotatable with respect to the member 45 and connected by a screwed member 50 carrying a ratchet disc 51 engaged by a locking pawl mounted on the fixed casing 44 and a driving pawl carried by the arm 47 of the member 45 to which the operating link 46 is connected. Excessive rotational movement of the members 45, 48 in applying the brake causes the driving pawl to slip a ratchet tooth so that the member 50 is turned during releaso to extend the members 48. Indicators, applications of.-To indicate the amount of wear that has been taken up, a crank member 38, 40, Fig. 2, carrying a pointer 37 is mounted in the casing 11 and engages a slot in the thrust member 25.

Filed: 1934-03-06
Abstract: 431,009. Charging batteries. MORRISON & SONS, Ltd., A. E., MORRISON, A. E., and MORRISON, A. C., Gartree Street, Leicester. March 6, 1934, No. 7115. [Class 38 (iv)] In a system for charging two or more 'batteries in series from the mains, each battery when charged is automatically cut out and replaced by a resistance, the main supply switch being opened when all the batteries are charged. Fig. 2 shows three batteries 27, 28, 29 on charge from the mains 7, each battery being connected at a charging point 56, 57, 58 together with its associated meter 50, 51, 52 by which the charging current is switched off when the battery is fully charged. When any battery, for example battery 27, is plugged in and switch 8 is closed by hand, a circuit is completed which includes lead 14 and winding 4 by which switch 1 is operated. This closes a connection from the main to the + pole of the plug 56 through a regulating resistance 43, switch 1 and lead 34. The - pole of the plug is connected by lead 37 to the control group for the next battery 28. Switch 1 also closes contacts 17 by which winding 23<a> of the main supply switch 23b is energized. When the battery 27 is fully charged, the meter 50 closes switch 53 whereby current is supplied to coil 11 thus opening switch 8. This breaks the circuit through . coil 4 of switch 1 which breaks the connection between the main and the + pole of the battery and instead passes current through the resistance 24 to the remaining batteries on charge. The main switch 23b is energized by any one of the contacts 17, 18, 19 in the control groups, these contacts being in parallel circuits, so that the switch remains closed until the last contact is opened. The automatic cut-out switches 8, 9, 10 and the contact devices 53, 54, 55 may be replaced by meter switches which are closed except when the batteries are charged, the batteries in this case energizing closing coils of switches 1, 2, 3. When any battery is charged, its meter switch opens and releases the corresponding switch 1, 2 or 3 thus making connection with the appropriate byepass resistance 24, 25, 26.
