A control system for moving the work-table of a machine in response to a pattern comprises a first motor C controlling the movement of the table in one direction and a second motor G controlling the movement of the table in another direction at right angles to the first direction. The motor C is controlled by leakage past a valve member 44 while the motor G is controlled by leakage past a valve 12. The valve member 44 co-operates with seats on the inner end of bushes 26, 28. The bushes have opposite screw threads 30, 32 and rods 38 extend between the bushes to prevent relative rotation. A knurled knob is connected to the bush 28 whereby rotation of the knob moves to the bushes towards or away from each other. The valve member 44 is carried by a rod 46 which is adjustably connected to a rod 62. The rod 62 carries a sleeve 68 which serves as an abutment for a member 72 connected to the valve 12. Tracing of the contour varies the bleed of the valves 12, 44 to control the speed of movement of the motors C, G.

Title: Improvements in or relating to hydraulically controlled distributor valves
IPC: F15B11/00
Filed: 1964-11-30
Abstract: 1,061,400. Hydraulic presses. ZAVODY V. I. LENINA PLZEN, NARODNI PODNIK. Nov. 30, 1964 [Dec. 3, 1963], No. 48531/64. Heading B5F. [Also in Division F1] An hydraulic system for controlling the movement of, e.g., a press plunger 1, comprises a filling valve 9 and distributing valves 4, 5, 6 operable in combination to stop, start, extend or return the plunger 1 by a piston 23a and the pistons 24, 25, 26 of servomotors 12, 13, 14, each movable by slide valves 15, 16, 17 arranged to coact with blocking slide valves 27, 28, 29 to ensure that the spaces 37, 38, 39 below the pistons 24, 25, 26 when unpressurized are always connected to the tank so that operation of the servomotors due to valve leakage &c. is precluded. As shown, the plunger 1 is stationary. To move the plunger 1 to the left the distributing valve 6 is opened to allow liquid in a line 18 connected to the return plungers 2 to pass to a tank 7, and low pressure liquid in a line 8 to pass to the plunger 1 through the filling valve 9 and a line 19. To continue movement at an increased rate the valve 4 is opened to direct highpressure liquid from a line 3 into a line 21 connected to the line 19. To return the plunger the distributing valves 4 and 6 are closed and the valve 5 is opened whereby high-pressure liquid in the line 3 passes to the line 18 and to a line 22 to upwardly move the piston 23a which opens the valve 9 to allow the plunger 1 to discharge liquid to the low-pressure line 8. The pistons 24, 25, 26 for opening the distributing valves 4, 5, 6 are each operated by moving the corresponding slide valve 15, 16, 17 into an upper position whereby control liquid pressure in a line 11 is directed to the respective spaces 37, 38, 39 below the pistons. In the position shown the spaces 37, 38, 39 are connected by the valves 15, 16, 17 to waste pipes 40, 41, 42. To operate the valve 6 the valve 17 is moved to connect lines 43, 44 whereby liquid from the line 11 flows to the space 39 through a path comprising a line 36, the blocking slide valve 28 and the lines 43, 44, 45. If for any reason the control slide valve 16 is changed, the space 39 is connected to the waste pipe 41 through the ducts 46, 44, 45 and the piston 26 returns to the position shown. Operation of the slide valve 15 in order to operate the distributing valve 4 interconnects ducts 49, 50. Hence pressure liquid flows from the line 11 through the ducts 36, 43, 44, 45, 49, 50 to the space 37 to lift the piston 24. Provided the valves 15, 17 are returned to their positions shown, the slide valve 16 can be lifted to operate the distributing valve 5. If either valve 15 or 17 is operated the space 38 is connected to the waste pipe 40 or 42 and cannot be operated.

In an arrangement for maintaining oscillations of a beater comb 1 in a textile machine, the comb 1 is formed integrally with a tubular shaft 2, one end of which is journalled in a bearing 3 whilst the other end is integral with a coupling 4 fixed on the shaft 5 of a single-phase or two-phase asynchronous electric motor 6 whose rotor is of squirrel cage form, and a torsion bar 8, coaxially mounted within the shaft 2, urges the shaft 2 and comb 1 resiliently into a median angular position. The torsion bar 8 has one end secured to the coupling 4 and the other end fixed to a plate 9 forming part of the bearing 3. On energization of the starter, the rotor is caused to vibrate, and its oscillations in opposite directions are resisted by the torsion bar 8. The frequency of oscillation is a function of the moment of inertia of the system and of the characteristics of the torsion bar. 1, 005, 154. Fire-proofing. AMERICAN CYAMID CO.

Title: Urea synthesis process
IPC: C07C273/04
Filed: 1963-12-12
Abstract: Urea is produced by reacting ammonia and carbon dioxide at an elevated pressure and recycling the unconverted reactants as an off-gas, said off-gas being formed at least in part by the decomposition of the ammonium carbamate in the aqueous urea product stream in a plurality of stages at successively lower pressure levels, the off-gas streams being recovered from each stage and substantially adiabatically compressed to the urea synthesis pressure by compressing each off-gas stream to the next higher pressure level and combining with the off-gas produced at that level, the final compressed off-gas stream being quenched by combination with the compressed input streams of ammonia and carbon dioxide and the combined input stream cooled by heat exchange. In a modified process, to remove inerts prior to ammonium carbamate decomposition, the product stream at the elevated urea synthesis pressure is passed to a vessel maintained at a pressure at least equal to the autogenous pressure whereby a mixed gaseous stream containing inerts, ammonia and carbon dioxide is generated from said process stream, said gaseous stream is cooled and refluxed and the inerts discharged substantially freed from ammonia and carbon dioxide, which reactants are recycled to the urea synthesis.  Substantially all of the exothermic heat of reaction of the urea synthesis, including the heat of ammonium carbamate condensation and the excess heat developed during off-gas compression, may be recovered as usable superheated process steam which is expanded through a power recovery turbine linked to the gas compressor or compressors so that a major portion of the power required for recycle gas compression is generated within the process of the invention.

Title: Hydraulic controls
IPC: E02F9/22
Filed: 1974-11-14
Abstract: 1466605 Fluid-pressure control circuits MASSEY-FERGUSON SERVICES NV 14 Nov 1974 [14 Nov 1973] 49261/74 Heading F1P [Also in Division E1] In a circuit, Fig. 3, in which an auxiliary pump P2 supplies fluid either to a line 3, fed by a main pump P 1 , or to a reservoir 19 under the control of a valve 14, which is changed over in response to a predetermined pressure level in an actuator 10, the circuit controlling changeover of the valve 14 includes a time delay device 13a. The latter prevents changeover occurring in response to transient pressure changes. As described, when the pressure in the actuator 10 reaches a predetermined level a switch 11 closes. The latter is in a circuit which includes the time delay device 13a. If the pressure level is maintained for the length of the delay period a switch 13d is opened by a solenoid 13c. This changes over the valve 16 to the position shown, in which the output of the pump P 2  is returned to the reservoir, from the alternative position in which the output is fed into the line 3. The latter position occurs on closing a switch 51 which is coupled to the engine driving the pumps. When the solenoid 16a is energized the pressure in line 3 is applied to the by-pass valve 14 to close it thereby diverting the output of pump P 2  from the reservoir to line 3. Fig. 4, (not shown), illustrates a circuit in which the solenoid 16a is energized only when one or other of control valves 4a, 4b is feeding  fluid to one of rams 9, 10, i.e. fluid from pump P 2  returns to reservoir unless one or other of rams 9, 10 is operating. In Fig. 5 an addition pump P3 supplies steering cylinders 42. A flow divider valve 22a is in the condition shown when the engine is running relatively slowly, the output of pump P3 is therefore low. The circuit is applied to a loader, Fig. 1, (not shown), which will be travelling relatively slowly and will therefore require a high steering rate. The flow from pump P 2  will be diverted to circuit 17b where it will contribute to this. If the engine is running at a high speed a lower actuator 22d will move valve 22a to its centre position and divert the P 2  output to either the steering circuit or to valve 14 whichever offers least resistance. If the engine is running at high speed and there is no steering demand the lower actuator 22d moves valve 22a into a third position in which all the flow from P 2  goes to valve 14.

Abstract: 1,195,018. Rotary fluid-flow meters. G.C. DAVIS. Nov. 1, 1967 [Nov. 4, 1966], No. 49472/66. Heading F1F. Apparatus for measuring mass rate of flow of a fluid includes a housing 1 containing resilientlycoupled coaxial tubular-rotors 8, 9 with blades 12, 13 internally thereof having different shapes and angles so that the rotors develop dissimilar torques. Resilient coupling of the rotors to each other is effected by magnets 16, 17 thereon, which extend into an annular groove 14 in the rotor 9 and tend to repel one another. Alternatively, the rotors are coupled to each other by a coiled spring (20), Fig. 3 (not shown). Further magnets 18 in the rotors facilitate detection by coils 19 of the angular velocity of the two rotors and the angular displacement of one rotor relative to the other, electric signals from said coils being used to determine the mass rate of flow, which is proportional to the ratio of said angular displacement to the velocity of fluid-flow. Fluid-filled gaps 24, 25 between the rotors and the housing and a similar gap 26 between the rotors constitute fluid bearings, fluid therefore being supplied through apertures 27.

Apparatus for moving a driven member 43, Fig. 2, by steps of a given amplitude comprises a peg 45 which is moved to connect member 43 with a stationary member 41 or with a driving member 42 when the driving member is stopped. The peg 45 is held in each position by spring pressed balls 70, 90 and is moved out of slot 421 when member 42 stops by a lever 81 which is rotated by a cam CO. The peg 45 is moved in the coupling direction by a lever 61 and electromagnet 63 controlled by a circuit 630 including cam-actuated switches C1-C3, relay 633 and switch 632, the cams being rotated in an order dependant on the intermittent rotation of member 42, Fig. 3 (not shown), to ensure that electromagnet 63 is energized at the correct instant during the period when member 42 is stationary. In Fig. 12, the driven member 43 can be rotated in steps of 180 degrees, the driving member 42 stopping after each 180 degrees; on release of a catch 65 by electromagnet 66 spring 64 rotates lever 61, provided cocking cam C31 is in the shown permission, to hold plug 45-1 in openings 431-1, 421-1 until rotation of member 42 carries the plug under surface 90; at 412 the spring 80-1 moves the plug out of opening 421-1 and a further plug 45-2 engages stop 411 and can be moved by lever 61 as desired. In Figs. 21, 22 (not shown) the plugs are moved out of engagement with the driven member by spring-pressed plugs in this member. The plugs may be moved parallel to the clutch axis; in Fig. 23 a lever 62, cocked by cams C31-2 on driven member 43, is released by mechanism 66 to press plug 45-1 to connect members 42, 43; a diametrically opposed plug 45-2 is moved out of opening 421-2 by spring 80-2 and engages in a semi-circular slot in stationary member 41.
