Abstract: 482,648. Fluid - - heater cleaners. BABCOCK & WILCOX, Ltd. June 30, 1936, No. 18149. Convention date, Dec. 3, 1935. [Class 99 (ii)] The tubes 22 of a fluid heater, Figs. 2 and 3, are cleaned by jets of cleaning fiuid discharged from two parallel blowing members 25, 26 and 27, 28 which are carried by a frame 29 slidably mounted on tracks 30 and are adapted to be traversed together below the tubes by a threaded shaft 60 which engages a valve casing 52, Fig. 7, on the frame through a nut 62 and a valve 57 reciprocable in said casing. The casing is located at the end of a pipe 50 also carried by the frame 29 and in communication with a tube 42 slidably mounted on the main cleaning-fluid supply pipe 40, and is provided with an inlet 53 from said pipe 50 and outlets 54, 55, the former being connected to the blower 27. 28 and the latter by a pipe 56 to the blower 25, 26. The arrangement is such that, with the frame 29 and valve 57 in the positions shown and upon rotation of the shaft 60 by a motor &c. 110, the nut 62 will travel along the shaft and a bracket 64 thereon and first effect movement of the valve 57 to the left, to connect the valve inlet 53 to the outlet 55 and permit cleaning fluid to be supplied to the blower 25, 26, and then abut against the casing 52 to cause the frame to move to the left; the left half of the tubes are thus cleaned. When the frame reaches the end of its stroke, the shaft 60 is reversed ; this effects reversal of both the valve 57 and the frame 29, so that cleaning fluid will be supplied to the blower 27, 28 to clean the right-hand tubes. As shown, the blower unit 25 is provided with a row of nozzles 35, spaced to correspond with the tubes of one row, and the blower unit 26 with nozzles 36, which are bent into alignment with the nozzles 35 and correspond to the tubes in the next row, and a transfer valve 75 is provided for directing the cleaning fluid from the pipe 56 to the two blower units alternately, the transfer valve being controlled by a pilot valve (not shown) which is actuated during movement of the frame 29 by its association with a cam rail located longitudinally below one of the tracks 30. Cleaning fluid is also supplied alternately to the units 27, 28 of the other blower in a similar manner. The supply of cleaning fluid is controlled by a valve 140 which may be actuated by a solenoid 141 located in the circuit of the motor 110, which includes a starting switch 120, in such a manner that the valve is always open during operation of the motor. The motor circuit mav also include two switches 121, 122 controlled by a member 124 associated with the shaft 60, the switch 121 effecting reversal of the motor when the blower frame reaches its extreme left-hand position and the switch 122 serving to stop the motor when the frame returns to its initial position. The valve 140 may, however, be hand-controlled and the motor circuit provided with a switch actuated by the pressure of the cleaning fluid.

Abstract: 1477316 Belt conveyer rollers BROCKWAY ENG CO Ltd 16 Oct 1974 [18 Oct 1973] 48563/73 Heading B8A [Also in Division F2] In an idler roller assembly for an endless belt conveyer, if relative rotation between a bearing element 218 and a roller spindle 200 takes place, engagement between the surface of a spindle portion 202 and the surface of a bore 26 in the element occurs and further relative rotation is prevented since the engagement becomes firm by jamming. This is the result of the surface bore 26 being eccentric with respect to a ball bearing whose inner race 241 is secured on the element 218, and of spindle portion 202 being eccentric to a portion 203 of the spindle 200. The manufacture of the element 218 and the preparation of the spindle portion 202 may be carried out by turning operation using an offset collet chuck. A bearing housing 211 has flats (212) (Figs. 1-3, not shown) for engaging jaws (221) of upstanding supports (22), the flats having abutments (213) which, in co-operation with the jaws (221), prevent longitudinal displacement of the roller. Specification 1,450,952 is referred to.

Fig. 5, is actuated by a player, the associated wheel 52 is forced down to engage the toy car more closely and increase the accelerating force. Each actuating mechanism consists of a bellows 78 which when squeezed causes a jet of air 80 to impinge on a flange 66 of a cam lever 68 accordingly turned about its pivot 66 so that a raised step cam surface 70 on each of two legs straddling the resilient spoked wheel 52 forces the shaft 54 and wheel downwards. As each car 16 leaves the accelerating device 20, it tilts an escapement lever 84, Figs. 3, 5 about its pivot 82 and steps round a lap counter 81.

Title: Preparation of nitrosyl sulphuric anhydride
IPC: C01B21/086
Filed: 1963-12-10
Abstract: Nitrosyl sulphuric anhydride (dinitrosyl pyrosulphate) is prepared by reacting sulphur trioxide and dinitrogen tetroxide in the vapour phase according to the equation N2O4 + 2SO3 --> N2O3.2SO3 + 1/2O2 at a reaction temperature preferably of from 200 DEG  to 550 DEG  C., and advantageously of from 350 DEG  to 450 DEG  C., the nitrosyl sulphuric anhydride being recovered from the resulting reaction mixture. Preferably, the process is continuous and uses a stoichiometric excess of dinitrogen tetroxide, the molar ratio of dinitrogen tetroxide to sulphur trioxide being preferably from 0.5 : 1 to 1 : 1, and advantageously from 0.6 : 1 to 0.75 : 1.  In a preferred embodiment of the process, the reaction takes place at a temperature of from 350 DEG  to 550 DEG  C. and the reaction mixture is cooled to a temperature of from 210 DEG  to 260 DEG  C. to separate a liquid fraction of nitrosyl sulphuric anhydride from a gaseous fraction of unreacted tetroxide, oxygen and residual anhydride, the gaseous fraction being then cooled to a temperature below 210 DEG  C. to solidify and hence remove the residual anhydride; the gaseous fraction may then be further cooled to liquefy the unreacted tetroxide which may be separated from the oxygen and recycled for the preparation of further anhydride.

Abstract: 1,084,527. Copying lathes. TRUE-TRACE CORPORATION. Dec. 15, 1964, No. 50956/64. Headings B3B and B3T. A copying device adapted to be mounted on the carriage of a machine tool such as a lathe comprises a base 19 with a slideway 20 which carries a first slide 21 actuated for longitudinal movement by a fluid motor 22. Slideways 25 on the slide 21 carry a transverse slide 26 which is actuated by a second fluid motor 28. The transverse slide carries a tool holder 54 and a copier valve 52 the stylus of which co-operates with a template 43 carried in an adjustable mounting assembly 35 attached to the base 19 by a bracket 36. The adjustment of the assembly 35 is by means of an adjustment slide 51 which permits the position of the copier valve and stylus to be pre-adjusted in relation to the template prior to the operation of the device. A control system effects the operation of the device in co-operation with the copier valve and includes a pair of positioning controls 61, 62 for manually controlling the longitudinal movement (along axis 17) and cross-traverse (along axis 27) respectively, a speed control 63 for the slide movements and a mode control 60 relating to whether facing or turning operations are being performed when the device is under tracer control. The copier valve 52 which has a gymbal type stylus mounting is of the multi-land piston type which is displaceable in response to the stylus movement from the template contour. The valve piston has three areas affecting operation, namely a safety cutoff portion, a contouring portion and a coordinator portion. The co-ordinator and contouring portions of the valve function in cooperation with each other to control the tool movements by so adjusting the speed of traverse to ensure precise following of the template by the stylus. The safety cut-off portion of the valve is operative when the stylus is overdeflected and in order to prevent the tracer valve being damaged. The speed control 63 adjusts the size of an orifice in an exhaust line from the valve which ultimately controls the rate of movement of the fluid motors. A diagrammatic circuit diagram, Fig. 3 (not shown), indicates the fluid operation of the device.
