Title: A process for the reduction of iron ore
Inventor: BRUNNER MIHALY
IPC: C21B13/00
Filed: 1967-11-10
Abstract: 1,211,025. Reducing iron ore. M. BRUNNER. Nov. 10, 1967 [Nov. 15, 1966], No.51238/67. Heading C7D. Iron ore e. g. magnetite is reduced by adding a gaseous, liquid or solid reducing agent, e.g. slack coal, coke breeze or oil, to a melt comprising 10-85% oxidic iron ore (Fe2O3) and 15-90% CaO in a furnace lined with a lime-containing refractory. The melt may be obtained by melting a finely divided mixture of iron ore and CaO or CaCO3. For continuous operation, ore is added at the same rate as iron is produced and CaO is added to bind the acid ingredients (SiO2 and P2 O5) in the ore to maintain an excess of oxygen ions in the melt. The process is preferably carried out in a rotary furnace, CO formed being burnt and the heat of combustion returned to the process.

Abstract: 1,115,459. Friction gearing. GENERALPRECISION SYSTEMS Inc. 6 Dec., 1965 [18 Dec., 1964], No. 51666/65. Heading F2Q. A toothless strain-wave type gear comprises an input shaft 18 frictionally driving freely mounted rigid planetary rollers 22a, 22b, 22c which roll around and distort a stationary resilient tube 14a into engagement with a larger diameter resilient output tube which is thereby outwardly distorted, the planetary rollers moving the tube distortions angularly for reduced rotation of the output tube 12a. In a modification, Fig. 3 (not shown), planetary spheres replace the rollers and are axially held by a groove on the input shaft. In Fig. 9 (not shown), the open end of the stationary flexible tube is closed for transmitting drive through a sealed wall. In Fig. 8 (not shown), the flexible tubes are conical and the transmission ratio is adjusted by axially adjusting the output tube (96) to vary the radial clearance between the undistorted tubes. Similarly, by making the tubes of different thermal expansion materials, the gear ratio varies with temperature. Fig. 5 (not shown) is a compound planetary train wherein the outer driven sleeve of a first train (e.g. 12, Fig. 1) is axially extended to form one input of a second similar train, having a second input formed by an extension of the first input shaft and driving additional planetary balls. An interposed sleeve corresponding to the stationary sleeve 14, Fig. 1, is the final output which may rotate forwards or backwards depending on the relation between the design sleeve clearances in the trains.

Filed: 1965-12-10
Abstract: 1,076,880. Couplings. AMP Inc. Dec. 10, 1965 [Dec. 29, 1964], No.52440/65. Heading H2E. A sleeve member 13 and a pin member 10, are used in a method of joining the ends of two coaxial cables, the resilient fingers at each end of the pin fitting in bores 7 in each of the inner conductor cores, while the sleeve member fits between the dielectric insulating material 6 of the cables and the outer conductors 5, each of the latter having a flared portion to accommodate the sleeve. Before assembly loading sleeves 8 are mounted on each cable, then the plug 10 is inserted in one of the bores 7 and the cables brought together to engage opposite ends of the sleeve 13. Further axial movement of the two cables towards one another locates the free end of the plug 10 within the remaining bore 7, and brings the cable ends together into abutting relationship. Finally the loading sleeves 8 are drawn over the flared portions of the cable ends, whereby pressure is exerted between the flared portions and the sleeve 13 thus providing good electrical contact. A rib 12 is provided in the plug 10 to ensure that equal lengths of the plug are located in each cable core, and a sealing ring 14 mounted on the sleeve 13 to provide a fluidtight seal. In a modification (Fig. 6A, not shown), the ends of the loading sleeves overlap while in a further modification (Fig. 8, not shown) for braided core conductors the plug 10 is replaced by a sleeve (10<SP>1</SP>) similar to 13, which fits between the core (4) and the insulation (6). In a still further modification (Fig. 9, not shown) for coaxial cables having an outer insulation, the cables are provided with clamping rings (20) with a rubber sealing ring 23 between them, the rings (20) being formed in one piece or of several arcuate parts.

A pneumatically operated vehicle gear change mechanism of the type disclosed in the parent Specification, includes a locking plunger 39 which is automatically pneumatically inwardly moved when top (i.e. 5th) gear is engaged to prevent movement of the gear shift lever 13, via an integral peg 54 on a selector plate 55, from the top (5th) gear to a gear lower than the next (i.e. 4th) gear until movement of the lever 13 into the 4th gear channel of the gate, or the door operating channel (D), outwardly releases the plunger to permit gear lever movement into the lower channels (3, 2 or 1) of the gate. Additional or alternative locking plungers may be provided for controlling movement of the shift lever between the other gear selecting positions in the gate as required. An additional channel (S) in the gate is the "start" position, movement of the lever 13 into which causes the gear selector plate 55 to close a micro-switch 67 connected across the starter motor for engine starting. The gear selector plate 55 is formed as a segment with a cam notched periphery engaged by a ball 52 spring and/or pneumatically loaded against the notched cam surface which is formed such that varying effort is required to move the shift lever 13 to various gear positions, the effort required depending on the position to be selected.

[Also in Divisions A4, B8 and F2] A mobile storage facility comprises three or more storage structures 23, 24, 25-29, Fig. 1, movable along a track 36, e.g. on rollers 38, Fig. 5, the end structures 23, 24 having oppositely moving drive means, e.g. the pneumatic cylinder PC1, Fig. 3, connected to the structure and its piston rod 52 connected to a fixed floor portion 56, whereby the structures may be moved together as in Fig. 1 or pulled apart to form an access aisle between a selected two structures determined by the selective uncoupling of coupling means 57-62 between the structures. The coupling means may be wholly manually operated or comprise a pneumatic cylinder e.g. LC1 on structure 23, Fig. 4, operating callipers 63 engaging a bolt 64 on structure 25, an emergency manual operating means being provided at 101, 94, 98, 102 and pull handle 103. A coupling actuator 93, 104, 106, 107 is carried by alternate structures connected by flexible hoses to a pneumatic circuit device 115 fixed in the floor and from which hoses lead to the drive means. To select an aisle e.g.. between 23 and 25, a button valve OB1, Fig. 4, is pressed to allow cylinder LC1 to open and uncouple callipers 63, the other couplings remaining connected, after which the circuit at 115 allows the drive means to be actuated to pull the two portions of structures apart to form the aisle. Should pneumatic tubes 108, Fig. 3, on the outer ends of the outer structure encounter an obstacle, a pneumatic signal sent to circuit 115 reverses the drive means and closes the structure. Similarly, if tubes 107 facing the aisle meet obstruction during closing, the drive means opens the structures. The aisle is closed by depressing valve buttom CB1 which closes callipers 63 which snap over bolt 61 due to return spring action of cylinder LC1 when the drive means push the structures together.
