Patent GB-689350-A (GB)
Title: Improvements in or relating to control mechanism for prime movers
IPC: F02D1/00
Filed: 1951-02-19
Abstract: 689,350. Fluid-pressure servomotor-control systems. CUMMINS ENGINE CO., Inc. Feb. 19, 1951 [April 24, 1950], No. 3960/51. Class 135. A governing system for a prime mover comprises hydraulic governing means responsive to the speed of the prime mover and auxiliary control means responsive to an operating condition of mechanism driven by the prime mover for modifying the effect of the governing means. The invention is described as applied to a Diesel engine driving mechanism through a torque converter, and the auxiliary control means is responsive to the speed of the output shaft of the torque converter so that when this speed tends to become excessive as a result of a light load, the speed of the engine is reduced. Alternatively, the engine may drive an electric generator or a hydraulic pump, and the auxiliary control means be responsive to the power output of the generator or to the pressure of the pump. The control means may also be responsive to a temperature of the driven mechanism. As shown, a sleeve 33, Fig. 3, driven by the engine carries fly-weights 53 which actuate a valve 42 for controlling the admission of pressure liquid from an annular space 43 to a cylinder 50 containing a piston 51 which, through a lever 62 and a lever and link 64, 65, Fig. 4, loaded by a spring 66, controls the displacement of a fuel injection pump of the kind in which a single pump supplies all the cylinders of the engine through a rotary distributor. A port 95 opening into the cylinder 50 at a position such that it is opened by the piston only at higher engine speeds communicates with a pipe 94 connected to ports 97 of a governor valve 92 responsive to the speed of the output shaft of the torque converter. Excessive speed of that shaft causes the valve 92 to be raised to bleed off liquid from the cylinder 50 to reduce the speed of the engine. A lever 74 adjustably pivoted at 75 and having an adjustable pin and slot connection 73 with the lever 62 varies the loading of a speeder spring 57 in response to movement of the piston 51 to provide "speed droop". A similar arrangement is provided for the speeder spring 91 of the governor valve 92, a connection with the piston 51 being made through the lever 64 and a link 113 connected to a lever 110. A modified piston 51 is described having an axial bore extending from the lower end to an intermediate annular recess which coacts with the bleed port to provide a gradual opening.

Title: Improvements in the mounting of parts or components to be machined between centres
IPC: B23B23/00
Filed: 1943-03-15
Abstract: 556,355. Turning. BOOTH, M. B., and BOOTH, L. B. March 15, 1943, No. 4167. [Class 83 (iii)] Components that require to be machined between centres, particularly short parts such as the removable ends of plug gauges that require machining to a very high degree of accuracy and that may vary slightly in axial length from the normal, are set up in the lathe in a manner that reduces errors in parallelism or taper due to angular deviation of the tailstock spindle from the lathe axis. To this end the tailstock centre b is adjusted to be on the true axial centre line at a distance from the headstock centre a considerably in excess of the length of the component and this distance is made up by means of an arbor or carrier f that engages the headstock centre at one end and the component h at the other. The component may be a driving fit in the end of the arbor or conversely.

Patent GB-745122-A (GB)
Title: Improvements in and relating to tubular furnaces for heating, distilling or cracking processes
Inventor: ROWELL GEOFFREY MITFORD
IPC: C10G9/20
Filed: 1951-02-28
Abstract: <PICT:0745122/III/1> <PICT:0745122/III/2> <PICT:0745122/III/3> In tubular furnaces of the type used for cracking petroleum oils, the convection zone of the furnace is separated from the combustion zone by a partition, the tubes carrying the liquid - to - be - heated pass through the partition, and are surrounded where they pass through the parition by sleeves which are of short length relatively to the length of the tubes.  In the cylindrical furnace shown in Fig. 1, metal tubes 10 are mounted vertically adjacent the refractory inner wall 3.  These tubes extend upwardly from the bottom of the furnace and project through the conical partition 5.  Extending through the refractory material in the bottom of the furnace are burners (not shown) to which combustion gases are supplied.  The partition 5 divides the combustion zone 4 from the convection zone of the furnace above the partition.  Sleeves 11 of mild or alloy steel are provided around the tubes where they project through the partition.  The combustion gases are caused to flow through the annuli 13 between the tubes 10 and the sleeves 11 in order to gain an exit from the furnace through the main flue 8.  The parts of the sleeves below the partition 5 radiate heat to the tubes, but above the partition heat is transferred by convection only; and the outer surfaces of the upper part of the sleeves may, if desired, be insulated.  The sleeves may be provided with a radial series of vertical fins 17 (Fig. 5). The partition 5 merges into a cylindrical flue 6 under the control of valve 7; and flue 6 opens into the main flue 8. Valve 7 enables part of the flue gases to by-pass the convection zone of the furnace.  In a modification, the sleeves 11 are of variable diameter (e.g. tapering) along their lengths, and may be flared outwardly at each end.  Where the tubes 10 are mounted in closely spaced relationship, two or more tubes may be enclosed in a single sleeve.  In a further modification, the annuli 13 (Fig. 4) may be formed by fluting the refractory walls of the furnace to give vertical channels 15 and by completing the annuli with metal walls 16.  The flue gases may be admitted into the annuli in a direction to impinge on the back or side of each tube only, rather than all round the periphery.  The general layout of the furnace may be inverted, i.e. the furnace may be fired from the top and have a bottom exit for the gases, or the furnace may be horizontally disposed.  Specification 567,634 is referred to.

Title: Apparatus for automatically parting-off continuously moving strip material
IPC: B23D25/00
Filed: 1966-02-03
Abstract: 1,072,836. Metal sheet feeds. H. GEORG, [trading as HEINRICH GEORG MASCHINENFABRIK]. Feb. 3, 1966 [Feb. 5, 1965], No. 4837/66. Heading B3W. A shearing line for dividing continuously moving strip metal 5 comprises a feed unit 1 which draws the strip from a roll and forwards it at a speed V to a pair of loop-controlling rollers 6 of which the bottom roller is driven at a speed V/2, a pair of braking rollers 7 of which the bottom roller is driven through a free wheel at a speed of about 3 metres/minute, a pair of high speed feed rollers 10 which are driven at twice the speed of the feed unit 1, a shear 2 which swivels about an axis perpendicular to the plane of the strip in order to make angled cuts across the strip, a driven roller table 3 which runs at the same speed as the high speed feed rollers 10, a pilot contact 14 and a gauging stop 13 which, when it is contacted by the leading end of the strip, initiates the operation of the shear. Operation.-The strip 5 is pushed, by the feed unit 1 through the loop-controlling rollers 6, the braking rollers 7 and the high-speed rollers 10, the upper roller of each pair being at this time raised, by a double-acting hydraulic cylinder, so that the strip passes through freely. A guide 11 leads the strip to the shear 2 and on to the roller table 3. When the leading end of the strip engages the pilot contact 14 the upper, rollers of the pairs 6 and 7 descend and engage the strip, the speed of which is then limited by the braking rollers 7 to a speed of 3 metres/minute. A loop 5a of material forms in front of the roller pair 6 and a second loop 5b forms in front of the roller pair 7. Since the surplus material delivered by the unit 1 is divided between two loops the height of the loops is reduced and the tendency of the strip to tilt sideways is also reduced. When the slowlyadvancing end of the strip contacts the stop 3 the shear 2 operates and during this time the strip is able to be stationary due to the free wheel included in the drive to the braking rollers 7. After the shear has operated the stop 13 is raised clear of the strip, the upper rollers of the pairs 6 and 7 are raised and the upper roller of the pair 10 descends and engages the strip to feed the strip rapidly forward, thus drawing material from the loops 5a and 5b. A delay relay raises the upper roller of the pair 10 after a predetermined interval of time and the strip is then fed forward by the roller table 3 at the speed determined by the feed unit 1.

IPC: B43K5/04
Filed: 1954-02-18
Abstract: 782,098. Reservoir pens. MABIE, TODD &.CO., Ltd. May 18, 1955 [Feb. 18, 1954], No. 4850/54. Class 146(3) A reservoir pen of the kind wherein endwise pressure applied by actuating mech-, anism to a leaf spring is adapted to cause a pressure to deflate a resilient sac, is characterized by the provision of connecting means between the actuating mechanism and barrel, such that on turning the barrel end in one direction the closing movement of the presser bar reaches a predetermined limit and is maintained but not increased on continued turning of the barrel end in the same direction, the presser bar being released for return to the inoperative position by a turning movement of the barrel end in the reverse direction. A collapsible sac 4, Fig. 2, is de-' flated by a presser bar 2 secured to a spring 3 given an endwise movement by a plunger 10 having a non-circular part 9 engaging a correspondingly shaped part in the barrel 1. The plunger 10 is moved axially of the barrel 1 by rotation of a knob 5 carrying a screw-threaded rod 25. The rod 25 has a reduced part 27 which holds the plunger 10 depressed when sufficient movement has been imparted to the spring 3, but permits further rotation of the knob 5 without effecting further movement of the springs. Rotation of the knob 5 in the opposite direction moves the spring 3 in the opposite direction to permit inflation of the sac 4. The knob 5 is retained against axial movement by a locking nut 26, on the rod 25, engaging a shoulder 15 on the barrel 1. In a modification, described with reference to Fig. 1 of the Provisional Specification, a knob 5 is screwed to a bush 14 which receives a screwed plunger 10 prevented from rotating by a hexagonal or non-round part 9 engaging a correspondingly shaped part 7. The bush 14 is prevented from moving rearwardly by a shoulder 15. Rotation of the knob 5 in the appropriate direction moves the plunger 10 axially towards the nib end to flex a spring 3 attached to a presser bar 2 engaging a sac 4. When the sac 4 has been deflated by actuation of the knob, further rotation of the knob 5 is ineffective, since the plunger 10 has a non- threaded reduced end 13. A clicking sound, produced by rotation of the knob upon disengagement of the threads, indicates that the sac 4 is deflated. Specification 782,099 is referred to.
