Title: A Method of Refining Ferro-Chrome
Inventor: KHITRIK SPIRIDON IOSIPOVICH
IPC: C22C33/00
Filed: 1967-04-20
Abstract: 1,159,196. Refining ferro-chrome. DNEPROPETROVSKY ORDENA TRUDOVOGO KRASNOGO ZNAMENI METALLURGICHESKY INSTITUT. April 20, 1967, No. 18197/67. Heading C7D. Ferro-chrome ingots are refined by subjecting them to an isothermal treatment at 1250‹ -1500‹C. under a pressure less than 1mm Hg. The process reduces the contents of carbon, nitrogen, hydrogen, oxygen and non-metallic oxide inclusions in the material. If the carbon content of the ferro-chrome is initially greater than 0À15%, a gaseous oxidizer such as oxygen, CO 2 , air or water vapour should be introduced into the treating furnace; gaseous oxidizer may also be introduced if the carbon content is less than 0À15% in order to accelerate the refining operation.
Patent GB-435099-A (GB)
Title: Improvements in and relating to power transmission clutches
IPC: F16D41/08
Filed: 1935-04-16
Abstract: 435,099. Clutches. McKENZIE, S. B., 47, Grosvenor Street, Toronto, Canada. April 16, 1935, No. 18201. Divided out of 435,148. [Class 80 (ii)] In a bidirectional roller clutch provided with a member which can be moved at will so as to render the clutch unidirectional, a positive force is automatically transmitted from the powerdriven shaft to said member when the said shaft again overtakes the other shaft, so as to return the said member and restore bidirectional running. The clutch comprises oppositelyacting sets of caged rollers l, s, one set l being arranged between cam pockets on a boss c, which is carried on the driving shaft a by a quick-pitch thread i<1>, and the cylindrical inner surface of a flange e on the driven shaft f, and the other set s being arranged between the cylindrical inner surface of a flange d secured to the shaft a and cam pockets on the outer surface of the flange e. A disc w, which is slidable on the shaft f and is connected for rotation with the cage t of the outer set of rollers s by pins y, carries conical projections z adapted to co-operate with conical recesses a<1> in the flange e. With the disc w in the normal position shown in Fig. 1, in which it is held by spring-pressed ball detents g<1>, bidirectional drive is transmitted. If disc w is moved to the left, by a control lever d<1> through a collar c<1>, the projections z co-operate with the recesses a<1> to turn cage t so as to render the rollers s inoperative, and the shaft f can now overrun. During overrunning, boss c moves to the left due to the thread i<1>. Disc w is maintained in its lefthand position by a spring f<1> until shaft a again takes up the drive, whereupon the boss c screws back to its right-hand position and in so doing moves back the disc w, through pins l<1> slidable in the flange e, to its normal position, restoring bidirectional drive. In a modification, the cage t is adapted to be turned through the medium of bell-crank levers pivoted on the flange e and actuated by a conical-ended collar slidable on the shaft f.

In a steering and driving axle arrangement having a universal joint 51, 52 in a driving shaft 12, the wheel hub 21 being mounted by two bearings 15, 20 on a swivel axle 19 supported on an axle casing 16, and a hub reduction gear connecting the hub and the shaft 12, the hub reduction gear is disposed between the bearings 15, 20..A gear wheel 25 is formed on the end of the shaft 12, and meshes with three pinions 26 mounted in a carrier 27 keyed to the swivel axle 19. The shaft 12 is journalled in bearings 53 and 24 which prevent and permit respectively, axial movement of the shaft 12. The gear wheel 25 is wide enough to permit it to partake in axial movement relative to the pinions 26. The universal joint comprises a pair of Hooke's joints 51, 52.

Title: Universal grinding machine
IPC: F16C29/02
Filed: 1960-05-24
Abstract: 880,089. Hydraulic apparatus. HEALD MACHINE CO. May 24, 1960 [July 13, 1959], No. 18246/60. Class 69 (2). [Also in Group XXIII] The wheel head table of a grinding machine (Group XXIII) is mounted on the base for sliding movement longitudinally thereof, the movement being effected by a pair of singleacting hydraulic linear actuators connecting the wheel head table to the base, each actuator consisting of a tubular body having a bushing at one end and a headless rod extending through the bushing, a passage extending axially through the rod for supplying pressure fluid to the interior of the body, at least one of the actuators having a damper formed therein to resist relative movement of the rod and the body at the end of a stroke. Hydraulic pressure unit 28, Fig. 16, mounted at the rear of the base 11 comprises a sump 172 having mounted on its upper wall a motor 173 driving a rotary hydraulic pump 174 delivering through conduit 175 to a valve box 26, a return line 177 connecting the valve box 26 to the sump 172. The wheel head table 15, Fig. 6, is reciprocated by opposed single-acting hydraulic linear actuators 66, 98 connected to the valve box 26 by conduits 79, 176. The actuator 66, Fig. 5, comprises a piston rod 67 secured to the base 11 and a cylinder 68 fastened by a collar 69 to the underside of the table 15. One end of the cylinder is closed by a cap 71 welded thereto and having an opening with a plug 73. The other end of the cylinder has a bronze bushing 74 retained in a counterbore by a snap ring 75. The piston rod has a bore 77 connected to the conduit 79. A piston 81 has a portion 82 in the bore 77 and a portion 83 projecting from the bore towards the cap 71. A bore 85 in the piston portion 83 is closed by a plug 86 and contains a spring 87 pressing a ball 88 against a seat leading into a small passage 89 opening into a bore 91 in the piston portion 82. The bore 85 communicates through radial ports 94 with the cylinder. The piston 81 is urged to the left by a spring 92 and is prevented from leaving the piston rod by a snap ring 84. An annular groove 95 formed in the wall of the bore 77 adjacent the inner end of the piston 81 communicates through radial ports 96 with the cylinder. The piston portion 82 has a flat 97 adjacent the groove 95. During the operation stroke, oil supplied through conduit 79 flows through the bore 77, presses the ball 88 away from its seat and flows through passage 89, bore 85 and ports 94 into the cylinder. During the return stroke, oil passes from the cylinder through ports 96 and groove 95 to the bore 77 and thence to the conduit 79; towards the end of the stroke the cap 71 strikes the piston 81 and displaces it so as to cover the groove 95, oil then escaping only through the space afforded by the flat 97, thus damping the movement.

In one form, Figs. 1 and 2 (not shown), a front vertical engine is carried on transverse tubes secured to the side walls of a bonnet compartment, the wall areas around the tubes being strengthened. by radial surface struts. As shown in Fig. 3, a rear engine a is mounted on a transverse angle bar g and an axle tube h, both of which are connected at their ends to side frames of the body structure, such frames extending beyond the rear wall l of the passenger compartment and being spring supported on the road wheels, whilst the axle shafts m pass through the tube h. In Fig. 5, the engine block is carried by pairs of stay-rods n, o, p incorporating shock absorbers r; and hinged to comer pieces at the junction of the rear wall l with the side walls. In the mounting of the engine on a transverse beam t, Fig. 6, rubber &c. shock absorbers s, u, v may be provided, the shock absorbers u, between the beam t and the vertical wall w being disposed, adjustably or otherwise, at unequal distances from the axis x of the beam to regulate the damping effect.

[Class 39 (i).] In a cathode glow tube having cold electrodes and a gas or vapour filling, the starting voltage is lowered by interposition of a gridshaped electrode, connected to the anode, between the main electrodes. The nature and pressure of the filling, and the distance between the main electrodes are so chosen that, in the absence of an auxiliary electrode, the starting voltage would be a minimum. The active cathode surface consists of an alkali metal layer applied to an alkali oxide. As shown, the disc-shaped nickel anode 3 and the grid-shaped auxiliary electrode 5 are mounted on a pole wire 6, and the disc-shaped cathode 4 on a pole wire 7. Caesium is liberated from a capsule 8 and is oxidized on the cathode by admission of oxygen. Caesium from the capsule 9 then adheres to the cathode. For a filling of neon with ¢ per cent argon at a pressure of 6 mms. the distance between the main electrodes is 15 mms.
