Abstract: 212,130. Glover & Co., Ltd., T., and Glover, W. R. March 22, 1923. Gas, supplying by meter. - In prepayment gas meters means operable from outside the meter are provided for disconnecting the prepayment mechanism from the bellows or operative mechanism to allow the prepayment mechanism to be zeroized and the valve closed, and to reestablish connection between the prepayment and operative mechanisms. In the application to prepayment. mechanism of the kind described in Specification 22830/94 in which the valve is operated by a slide carried by a pinion working between two worms rotated by the coin and meter mechanism respectively, the worm F rotated by the meter has a wheel 1 gearing with a worm 2 on a shaft 3 at right angles to the worm. A wheel 4 on the shaft 3 meshes with a pinion 5 on a. parallel shaft 6 which has a wheel 7 meshing with a pinion 8 on a stub shaft mounted between brackets 9, 10. The stub shaft has a wheel 11 meshing with a worm 12 driven by the bellows or operative mechanism. One end of the shaft 3 has a loose bearing in the bracket 10 and the other end extends outside the meter casing where it is provided with a knob 15 and a ratchet 16 controlled bv a pawl 17 to allow rotation in one direction only. A catch piece 18 pivoted to the meter casing and controlled by a spring 22 has two recesses for holding the shaft 3 in placed position. To close the valve and zeroize the prepayment mechanism, the catch piece 18 is lifted and the shaft 3 is moved sideways to engage the second recess in the catch piece thereby disconnecting the wheel 4 from the pinion 5 and the meter operative mechanism. The shaft 3 is then rotated to actuate the worm F and close the valve. On moving the shaft 3 back to engagement with the first recess in the catch piece, the wheel 4 will again mesh with the pinion 5. The end of the shaft 3 is enclosed in a hinged casing 21 capable of being locked.

Title: Improvements in pressure treatment of coking coals
IPC: C10L9/06
Filed: 1941-07-03
Abstract: 547,376. Coking processes ; materials for making coke and other products. AMERICAN CYNAMID CO. July 3, 1941, No. 8428. Convention date, July 2, 1940. [Classes 55 (i) and 55 (ii)] The coking characteristics of swelling and caking coal are altered by pulverizing the coal and subjecting it to controlled oxidation in the presence of air or oxygen at high pressure, such as 45 to 150 lbs. per square inch, and at high temperatures, such as 115‹ to 200‹ C. The coal should be dried before the oxidation treatment. The coal is ground in a pulverizer 1 to pass a 20 mesh screen and the temperature is controlled by the admission of hot flue gases from a furnace 4. Air from a fan 3 carries the coal particles through a pipe 6 to a cyclone dust collector 7 where most of the coal is collected, the remainder returning with the air current to the fan 3 for recirculation. A smaller fan 8 removes air from the main current and blows it through a collector 9 from which the coal returns to the pulverizer. The hot dry coal is fed bv a pumo 10 through pipe 11 to pressure vessels 14 in which it is put under 50 lbs. per square inch pressure for 4 hours. Air under pressure is heated in a coil 13 and supplied to the coal passing along pipe 11, and to the pressure vessels. The resulting product is discharged into a bin 16. The oxidized coal, when mixed with a binder such as coal tar, or pitch, or sulphite liquor, or molasses, and formed into briquettes, may be carbonized to yield a briquette resistant to pressure, the load bearing strength of the briquette being in some cases improved by preheating in air to 200‹ to 240‹ C. prior to the carbonization.

Title: Body joint endoprostheses
IPC: A61F2/00
Filed: 1976-03-03
Abstract: The prosthetic articulation comprises a shaft (73) for anchoring in a first bone (30), a first articulation part (113) which is connected to the shaft and forms the articulation together with a second complementary articulation part on a second bone (48), and a support element (107) which is connected to the shaft and bears on a bearing surface of the first bone. In order to ensure that the force introduction into the first bone takes place in a physiologically analogous manner, so that the distribution of stress corresponds as closely as possible to the physiological distribution of stress, the first articulation part (113) and the support element (107) form a pivot part (109) which is connected to the shaft in an articulated or resilient manner. To insert and remove this prosthetic articulation, use is made of a rigid turning instrument which can be applied to coupling means (87) on the shaft of the prosthesis or can be coupled securely to these means. <IMAGE>

Title: Improvements in or relating to control valves for liquid pressure control systems
Inventor: SENIOR WILLIAM JAMES
IPC: F15B13/043
Filed: 1960-03-10
Abstract: 911,708. Fluid-pressure servomotor-control systems. AUTOMOTIVE PRODUCTS CO. Ltd. March 10, 1961 [March 10, 1960], No. 8527/60. Class 135. A valve controlling the supply and exhaust of fluid to and from a double-acting ram has a body 15, Fig. 2, with a bore 18 incorporating grooves 19-24 and housing a slidable valve spool 25 with grooves 26-29; groove 22 is always open to an inlet passage 30 connected to a pump, and grooves 20, 24 are open to a drain port 33, Fig. 4, which is separate from another drain port 32, Fig. 2, in communication with groove 19. Pressure chambers 36, 37 are formed one at each end of the bore 18. The inlet passage 30 is surrounded by a groove 38, Fig. 4, which is intersected by a duct 39 that opens into each of the chambers 36, 37 via a calibrated orifice; the end of passage 30 adjacent the groove 38 is closed by a screwed plug 42, a part of the threads of which are mutilated to provide for a restricted fluid flow into the groove 38. Chamber 37 is also connected by a passage 44, Fig. 2, with the drain port 32, the area of entry to the passage 44 being adjustable by a screw 45. the end of the spool 25 within the chamber 36 has an axial bore 47 connecting with groove 19, the outer end of the bore 47 co-operating with a needle 49 passing through a chamber 50 with its own drain port ; the needle 49 is actuated by a solenoid 53 having two oppositely-wound coils 54, 55. If the screw 45 restricts the fluid leaving chamber 37 more than the orifice in the duct 39 impedes the fluid supplied thereto then the spool 25 will tend to move leftwardly; if the needle 49 effects a greater restriction of flow through the bore 47 from chamber 36 than is offered by the other orifice in the duct 39 then the spool will tend to move rightwardly. The spool 25 is normally in the central position wherein it isolates both ends of the ram from the supply and drain. Any change in the relationship between the currents in the coils 54, 55 displaces the needle in one or other direction so altering the pressure in chamber 36 and causing movement of the spool to a position where it resumes its normal relationship to the needle 49 and the pressure in chamber 36 is again balanced by that in chamber 37. In a modification, the valve is arranged to control fluid to one side only of a ram piston.

Title: Gear change mechanism for motor vehicles
IPC: F16H63/04
Filed: 1929-03-16
Abstract: 325,146. Stanley, G. E. March 16, 1929. Variable-speed gearing.-To facilitate change of speed, a constantly meshed wheel 4 can be freed from a layshaft 5 by means of a positive dog clutch which is interconnected with either the main clutch or the changespeed mechanism so that during a change of speed the layshaft is relieved of the inertia of the main clutch &c. The positive clutch may comprise a sliding dog, or as in Fig. 1, the wheel itself may have two internal rows of dogs 6, 7 engaging dogs 8, 9 on the shaft, alternate end portions of the dogs on each row being cut away to facilitate engagement. The driving wheel 2 is wide to ensure mesh in all positions of the wheel 4. For operation from the main clutch, Fig. 2, the striking fork, slidable on a rod 15 is biased by a spring 16 and the fork is withdrawn by an extension 21 of the main clutch lever 22, which moves a bell crank lever 18 through a spring loaded plunger 19. The latter spring is substantially stiffer than the spring 16 so that depression of the clutch pedal always frees the main clutch even if the torque on the dogs is too great for them to disengage, the reduction of torque consequent upon declutching allowing the spring to affect disengagement. The main clutch can thereby also engage even if the dogs come opposite one another upon engagement. Alternatively, the plunger 19 may be adjustably fixed in the housing 20 and when the clutch pedal is fully raised there may be clearance between the plunger and the arm 18, and a further modification comprising lost-motion means at 22a allows adjustment of the main clutch member. In this case, the stiffer spring and the operating plunger may be carried in a recess in the boss of the fork. The fork may also be located resiliently between collars on the shaft. When the operating-means are interconnected with the change-speed lever, Fig. 4, the fork is moved by a pivoted lever 23, the upper end of which carries a lateral peg 25 engaging a V-shaped slot 26 in a member 27 moved by the change-speed lever 31. The slot is such that whichever way the lever is moved from the neutral position (Fig. 4) the wheel 4 is always reclutched. In a modification, the slot is replaced by a corresponding cam surface. In order to facilitate engagement of a sliding gear when the car is stationary, the wheel 4 may have a conical end surface which, when completely declutched, is pressed into engagement with a corresponding surface associated with the layshaft by means of a spring-loaded plunger 34 having limited axial movement.

Title: Improvements in magneto electric ignition machines
IPC: F02P1/00
Filed: 1924-04-07
Abstract: 213,930. Neighbour, A. G. L. April 6, 1923, [Convention date]. Magneto-electric machines.-In ignition magnetos the high-tension current is caused to traverse an air-gap in passing directly from the secondary winding of the armature to the rotor of the distributor or to a fixed collector, thus dispensing with brushes in connection with the armature, a safety spark-gap being formed between an earthed electrode and the electrodes connected to the armature winding. Fig. 4 shows diagrammatically a ring 14 provided with electrodes 13 connected to the secondary winding S and rotating with the armature, the current passing as sparks to electrodes 22 on a ring 23 built in the rotor of the distributor 24. The shafts of the armature and of the distributor may be parallel as shown in Fig. 4. or inclined to each other as shown in Fig. 3. In the construction shown in Fig. 3, the distributor has only a single electrode 22a to which the current passes from the armature electrodes 13. The rings 14, 23 are embedded in insulating-material from which the electrodes project radially, but where a large number of electrodes are necessary they may be replaced by a continuous ring. An electrode 38 fixed in the outer casing provides a safety spark-gap. In a machine not provided with a distributor a singles electrode 13, Fig. 7, is fixed on the end of the armature and coacts with fixed collector electrodes 22<b> and with a safety spark-gap electrode 38. In this machine, apertures in the end cover 31 permit the escape of products of ionization, and in the machines shown in Figs. 3 and 4 a fan 39 on the armature shaft draws air in from apertures 42 and expels it through apertures 36.
