Title: Production of hydrogen
IPC: C01B3/10
Filed: 1947-05-28
Abstract: <PICT:0628417/III/1> In a continuous process for producing hydrogen by reacting steam with a metalliferous reducing agent, e.g. iron, ferromanganese, ferrochrome, ferrous oxide, mixtures of copper oxides and iron, or manganese oxides, of the type in which the reducing agent is maintained as a dense fluidized bed in a reactor, while spent reducing agent is continuously withdrawn, passed to a regenerator wherein it is regenerated as a dense fluidized bed, and recycled to the reactor, the regenerator is at a higher level than the reactor, the reactor is at a higher pressure than the regenerator, and the regenerated reducing agent is recycled through a standpipe as a dense fluidized column whose fluistatic pressure is sufficient to compensate for the pressure differential between reactor and regenerator.  Preferably the regenerator is at a higher temperature than the reactor, and the heat for hydrogen generation is provided by sensible heat of the recycled reducing agent. Superheated steam with ferrous oxide from standpipe 40 pass through pipe 1 to dense bed of generator 10, at 800-1500 DEG  F. and up to 100 atmospheres or higher pressure, and hydrogen is withdrawn through separator 12, while spent ferrous oxide is returned through reverse standpipe 18 as a phase of progressively decreasing density to regenerator 30 at 800-1700 DEG  F., and atmospheric pressure either through aerated line 22 or branch 18a. A fuel and/or regenerating agent, e.g. methane, water gas, impure hydrogen, liquid hydrocarbons, or fluidized solid such as coal or coke with air or oxygen is supplied at 28 and regenerator 30 may have countercurrent flow by use of two or more superimposed dense beds 26, 26a with overflow 40a, while more fuel and/or regenerating agent may be supplied at 52. Regenerated reducing agent is returned to fluidized standpipe 40 which may be 50 to 200 feet high to give the necessary pressure difference between the generator and regenerator.  Specifications 578,323 and 586,914 are referred to.

Title: Method of and apparatus for hot-dip coating strands
Inventor: HARRIS ARCH WESLEY
IPC: C23C2/32
Filed: 1962-04-12
Abstract: 933,230. Coating by dipping. UNITED STATES STEEL CORPORATION. April 12, 1962, No. 14253/62. Addition to 891,295. Class 82. The apparatus and method of the parent Specification is modified so that on leaving sinker 26 there is provided a means for positively dampening the vibrations of the strand S e.g. of steel in a non-oxidizing atmosphere before the strand discharges into the air, by siting an enclosure 30 at and above the molten metal surface where the strand leaves the bath 20, e.g. of aluminium; said enclosure supporting therein a deflecting bar 28 in contact with, and determining the degrees of deflection of strand S. Combustible gas, e.g. natural gas, is admitted at 32 to maintain a non-oxidizing environment both where the strand leaves the melt and also around the zone where the strand contacts the deflector bar; this gas discharges around the strand where the strand leaves the enclosure at cut-away 31 (see Fig. 5 not shown) and burns on contact with theair, the burning gas promoting flow-back of excess coating metal. For effective dampening of the vibratory energy in the strand by bar 28 contact must be made within 1¢-3 ins. of the bath surface. To permit observation of the contact of strand S with bar 28 a sight tube 29 is provided. The degree of deflection is controlled by varying the position of enclosure 30 through the agency of movable support arm 30B.

Abstract: 925,387. Single leaf springs. ROCKWELL-STANDARD CORPORATION. April 20, 1961 [April 20, 1960], No. 14261/61. Class 108(3). A single leaf spring having tension and compression surfaces on opposite sides has one of the surfaces at least formed with a taper roll portion of approximately parabolic longitudinal contour of decreasing cross-sections from an intermediate attachment portion to an end portion, the attachment portion being thicker than the maximum thickness of at least one of said tapered portions and providing a surface having an abrupt discontinuity of the parabolic surface. As shown a leaf spring 10 for a vehicle, composed of front and rear tapered portions 24, 22 with substantially parabolic under surfaces 23, 21, is made of a single length of good quality steel and has an intermediate attachment area 30 of increased thickness in order to reduce the stress and the risk of failure e.g. due to fretting at this area. The latter is clamped by means of U- bolts 18 to a transverse axle housing 20 eyes 26, 28 at the forward and rearward ends of the spring being connected respectively to a bracket 14 on the frame member 16 and a shackle 12. The eyes 26, 28 are omitted when the ends of the spring merely bear on the frame or axle. The thickness of the attachment portion 30 can be up to 200% of the maximum thickness of the tapered portion. It may be necessary to provide a single leaf spring with a rate ratio between the front and rear halves of the spring in which case it would not be necessary to provide an increased cross-section at the attachment portion for either the front, or rear, half of the spring.

Title: Improvements in or relating to timing compensator
IPC: B24B47/06
Filed: 1958-05-06
Abstract: 857,104. Telemotors. THOMPSON, E. A. May 6, 1958 [May 6, 1957], No. 14502/58. Class 69 (2). A telemotor system comprises a cam-actuated transmitter 16a, a receiver 62 and a diverting element 40. The receiver and diverter are biased against the transmitter by accumulator pressure which effects the return stroke of the transmitter and maintains follower 14a always in contact with cam 12a. The piston 40 is differential and moves in a cartridge 32 which may be reversed in bore 30, so that the piston may present either of two faces to the accumulator pressure. Intermediate in area between the areas of these two faees is the piston face of piston 62 open to accumulator pressure. When pressure is applied by the transmitter in the arrangement shown in Fig. 5, diverter piston 40 moves first until it reaches adjustable stop 48, whereupon the receiver starts to move. On the return transmitter stroke, liquid is returned first by the receiver and then the diverter. With piston 40 in the reverse position, the order of actuation is reversed. Valve 55 is a combined relief and replenishing valve. Several such telemotor units may be combined to control the movements of a machine-tool.
