Title: Improvements in or relating to cut-out devices for groups of pneumatically operated switches
IPC: B60L15/34
Filed: 1924-09-18
Abstract: 225,180. Meyfarth, G., and Soc. Anon. des Ateliers de Secheron. Nov. 22, 1923, [Convention date]. Controllers, actuating, interlocking.-The cutout lever 21, Fig. 1, of an electric vehicle is arranged to open the individual pneumatically operated contacts 16, irrespective of the position of the controlling hand-wheel 20, the action of which is thereupon suspended until it is brought to its zero position. The arrangement is shown as applied to a single phase supply, in which the contacts on one side are connected to a tapped transformer and on the other side to the motor. Rotation of the hand-wheel 20 causes a nut 7 to be traversed along a screw 6, a cam 8 on the nut 7 sequentially lifting valve rods 10, thereby causing the corresponding contacts to close. Locking-rods 19 on each switch co-operate with lugs 9 on the nut. Movement of the lever 21 causes arms 22, 23 to turn about their pivots and depress a connecting-rod 24, which pulls the cam 8 downwards against the action of springs 27 and allows the contacts to open. Reverse movement of the lever 21 does not raise the rod 24 owing to a pin and slot connection 22<3>, 28, the cam 8 is therefore not returned to its operative position until the nut 7 has been returned to its zero position where it engages an arm 22<2> and turns the arms 22, 23 to their initial position. In the arrangement shown in Fig. 3, slow backward rotation of the wheel 20 causes the switches to operate in the normal reverse order, whereas quick backward rotation opens all the switches suddenly. The quick movement of the nut 9 causes a releasing lever 22 pivoted thereon to contact with a, locking rod 19, as the corresponding switch has not had time to operate and lift the rod 9. The lever 29 therefore withdraws a pawl 30 from a lock 31 which is urged to the left by a spring 35, and which by reason of cams 32 thereon pulls the cam 8 downwards. Thereafter it is necessary to return the nut 7 to its zero position so that the lock 31 contacts with a fixed stop 34 and is returned to its normal position. In two other arrangements the screw 6 and nut 7 are replaced by a rotating cam-shaft, which is axially displaced for effecting the sudden opening of the switches, the axial movement being imparted either by the lever 21 or by quick backward rotation of the hand-wheel 20. In a further arrangement using a cam-shaft, initial movement of the lever 21 effects opening of the switches and also mechanically disconnects the hand-wheel 20 from the cam-shaft, further movement of the lever 21 returns the cam-shaft to its zero position.

Abstract: 949,235. Stretching rings. UNITED STATES STEEL CORPORATION. June 21, 1961 [June 21, 1960], No. 22462/61. Heading B3E. A method of expanding cylindrical rings includes the steps of placing the opposite open ends of an unexpanded ring B between an expanding mandrel 4 and a platen 2 and, by movement of said mandrel and platen toward each other to force said ring over said mandrel into a partially expanded state where the trailing end of said ring is over the mandrel, withdrawing said platen 2 relative to said mandrel and inserting a second ring to be expanded between said platen and the unexpanded end of said first ring, and moving again said platen and mandrel toward each other to force the trailing end of the first ring beyond said mandrel and expand the second ring into such partially expanded state. The first ring drops into the base 15 of a part 3 supporting the mandrel 4 and the ring is removed therefrom after removal of the mandrel 4 from the part 3. The mandrel surface is lubricated prior to the ring expansion. The mandrel 4 may be conical. The last ring B forced on the mandrel may be fully expanded by stripping the partially expanded ring from the mandrel reversing it, Fig. 10, and pushing it down on the mandrel to complete the expansion. It may then be pushed off the mandrel by a fully expanded ring pressed down by the platen 2.

Abstract: 433,344. Windscreen-cleaners. AC SPARK PLUG CO., Flint, Michigan, U.S.A. Aug. 2, 1934, No. 22534. Convention date, Aug. 4, 1933. [Class 138 (i)] [See also Group XXXI] Windscreen - cleaner mechanism comprises a power - transmitting shaft between the wiper and a power source, means being provided movable into engagement with the shaft to move it axially and effect its release from driving engagement with the power source, and movable out of engagement with the shaft when the latter moves into driving engagement. In the construction shown, the wiper blades are adapted to be operated from a part of the vehicle for example, shaft 33 of a generator 35. The shaft 33 has clutch elements 63 co-operating with clutch elements 61 on the head 59 of a shaft 57 forming an extension of a flexible cable 31. A spring 53 acts to effect the engagement of the clutch. The cable 31 at the other end enters a housing 27 and is provided with a sleeve 71 carrying a collar 73 and splined on a shaft 37. The collar is adapted to be engaged by the end 101 of a rack 95 which meshes with a pinion 93 mounted in the housing 27. The pinion shaft 81 carries a handle 83 by which the shaft may be turned to operate the rack, thereby to engage or release the clutch at the remote end of the cable. When the clutch is engaged the end 101 of the rack is withdrawn from contact with the collar 73, as shown in dotted lines in Fig. 5, the withdrawal being effected by the action of a torsion spring 105. To prevent undesired movement of the rack 95, the shaft 81 is provided with a pin 85 urged by a spring 89 into engagement with a notch 87 in a boss 148 formed in the cover of the housing 27. The boss has a ramp 149 adapted to assist the spring 89 in the completion of the movement of the handle 83 to engage or release the clutch. The shaft 37 drives through worm gearing 109, 111 a shaft 113 clutched to the worm wheel 111 by means including a pin on the shaft 113 urged to engagement with the wheel by a spring. The shaft 113 carries a crank 123 to which are connected links 129, 131, provided with pivoted segmental gears 135<1>, 135, respectively, each adapted through a pinion to cause the oscillation of a shaft carrying a wiper blade 147. To provide for the blades oscillating in opposite directions, the arm connecting gear 135<1> to the link 129 extends upwardly from the gear, and the corresponding arm associated with the link 131 extends downwardly.

Title: Improvements relating to steel shot
IPC: B24C11/00
Filed: 1961-06-22
Abstract: Abrasive steel shot pellets for shot blasting, containing less than 1.7% carbon wherein the carbon content increases towards the core, which is preferably hypereutectoid, are manufactured by heating iron pellets containing carbon to a temperature between 1650  DEG F. and their melting point to cause the carbon to migrate towards their surfaces, and passing a continuous flow of oxygen over the pellets to burn off the migrated carbon, prior to cooling. As shown in Fig. 1, graded iron pellets, such as prepared by quenching droplets of molten grey iron dispersed by blasting a stream of the molten metal poured from a cupola, are continuously passed from a bin 10 through a preliminary heating tube 15 in which they are heated to between 900 and 1200  DEG F., transferred via hood outlet 20 to a second tube 22 through which they are passed and heated to between 1650 and 2250 DEG F. whilst oxygen is passed over them, and finally cooled in a cooling tube 27, itself water cooled from a spray nozzle 28, or quenched in a bath. Heating and movement of the pellets is accomplished by burnt fuel gas flowing through the tubes 15, 22 from burner nozzles 17, 23, the latter also supplying the oxygen (see Division F4).  The pellets are tumbled by rotating the open-ended tubes 15, 22, 27 on wheels 33, 34, 35 respectively. The lining of the tube 22 may be initially of carbon steel which is then treated in the same way as the pellets before it is used for the process. <PICT:0951812/C3/1>
