Title: Apparatus for driving an object along a path or orbit
Inventor: ROYLE JOSEPH KENNETH
IPC: G05D3/14
Filed: 1958-06-13
Abstract: 893,207. Automatic positional control systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 11, 1959 [June 13, 1958], No. 18924/58. Class 38 (4). [Also in Groups XXXVIII and XL (c)] In a remote positional control servo system, the object to be positioned (a radar scanner or machine tool element) is driven by the combined outputs of an hydraulic motor which is capable of a high initial acceleration but has a low maximum velocity, and an electric motor capable of a high velocity but providing poor acceleration. The motors are controlled by incremental pulses recorded on a magnetic tape. The shaft 10 carrying a radar aerial is driven by the hydraulic motor Q and, through a sun and planet-wheel system 1 by the electric motor M. Alternatively, Fig. 9 (not shown), the electric motor may have a " stator " driven by the hydraulic motor. The electrical control signal may be applied in parallel to both motors, or the hydraulic motor may close a centrifugal switch, Fig. 4 (not shown), to energize the electric motor only when the hydraulic motor has reached a given velocity, or the signal may be integrated as in Fig. 2, before being applied to the electric motor, or the signals for the two motors may be obtained from separate tracks of a magnetic programme tape, Fig. 8 (not shown). If the scanner is reversible, two centrifugal switches are controlled through oppositely arranged free-wheels so as to control reversing contacts, Fig. 5 (not shown), in the circuit of motor M, which is a 3-phase motor. If the motor M is controlled by integrating the signal to motor Q, the integrated signal may be compared, Fig. 6 (not shown), with the output of a tachometer generator and any unbalance used to control a pair of triodes, Fig. 7 (not shown), which energize forward and reverse relays to run the motor M in the required direction. The position of the shaft may be detected by a disc 12, Fig. 2, carrying a radial diffraction grating which forms moirÚ fringes with a fixed reference grating 16, the fringes being detected by a photo-cell 18. The number of pulses generated by the fringes is compared at 24 with the number of pulses representing increments of movement recorded on a magnetic tape 22 and any error used to energize the driving motors. If the radar scanner is ship-borne the reference grating 17, photo-cell 18, &c. Fig. 3, are mounted on a bracket 14 which can rotate about the shaft 10 and is positioned through a linkage 28, 29, 32 to a directional gyro 33 so that movements of the scanner are made relative to a fixed directional reference instead of having the yaw of the ship superimposed.

Title: Improvements in and relating to the production of ethylene
IPC: C07C11/04
Filed: 1951-08-15
Abstract: A continuous process for producing ethylene by pyrolysis of cracked gas obtained by fractionation of cracking products of liquid hydrocarbons comprises de-acidifying or removing H2S and CO2 from all or a major part of said gas, pyrolyzing an ethane and/or propane fraction recovered from said de-acidified gas, together with acidic gases recovered from the de-acidifying step or with the minor part of the initial gas which was not de-acidified, blending the pyrolysis product with the de-acidified gas, and fractionating the mixture to recover ethylene, and an ethane and/or propane which is sent to the pyrolysis step.  The amount of acidic gases or de-acidified initial gas in the p  pyrolysis feed is generally adjusted to give an acidic content of the feed of 0.01-0.3 per cent by volume when coking and corrosion are reduced.  Steam is preferably added to said feed in a proportion of about 6-20 per cent by weight.  The initial cracked gas preferably has a negligible content of C4 and above.  It may comprise thermal and/or catalytic cracking products. De-acidifying may be effected with aqueous diethanolamine, caustic soda or alkali phosphate, the feed gas then being mixed with pyrolysis gas, scrubbed to remove residual acids, cooled, and dried.  Low temperature fractionation may then be used to separate methane and fixed gases, ethane, ethylene, propane, and propylene.  Pyrolysis is effected in stainless steel tubes, generally at about 1425-1510 DEG  F., a feed inlet pressure of 90-95 p.s.i., and contact time of 0.7-1.3 sec.  The product is quenched, mixed with de-acidified feed gas, and separated into its components.  The effect of varying amounts of H2S on coking and corrosion in pyrolysis is illustrated.

Abstract: 496,766. Removing metal by oxidizing gas streams. LINDE AIR PRODUCTS CO. July 16, 1937, No. 19690. Convention date, July 16, 1936. [Class 83 (iv)] In apparatus for removing metal from the ' surface of a metal body such as a steel billet, one, or a number, of blowpipes for applying an oxidizing gas stream obliquely against said surface, are movable into or out of operative position relatively to a carrier which movement simultaneously controls in each blowpipe the gas supply thereto. The billet P, Fig. 1, is mounted on a table T which is moved along under the blowpipes N or the latter are moved over the surface of the work. A support K is arranged for vertical and lateral adjustment and carries, pivoted to it at 14, a clapper 15 the lower end of which abuts an adjustable stop 49. Pivoted to one of the vertical edges of the clapper is a U-shaped carrier 22, Fig. 2, which may be adjusted to set the blowpipes at an angle to the work-axis by a nut 46. Upper and lower parallel links 35, 36 respectively, Fig. 1, are pivoted within the carrier and support uprights 38 to which the blowpipe units 40 are fastened for a limited amount of horizontal rotation. Stops 86 on the upper links limit the downward movement of the blowpipes and compression springs 91 bearing against extensions of the upper links tend to maintain the blowpipes in their lowermost operative positions. Handles 51, 52, 53, Fig. 2, operating through wires, enable the blowpipe units to be raised out of their operative positions and held in a raised inoperative position. Three blowpipe units may be connected by a bar 64, Fig. 5, to be raised simultaneously by one handle while two further units 38 are individually operable by the other two handles. Links 84, Fig. 1, are connected to the uprights supporting the individual blowpipe units and when the latter are moved upwardly, either by striking an obstruction or by the handles, a cam-piece 83 fastened to the link 84 slides within a valve chest V supported by the carrier 22 and shuts off the supplies of desurfacing oxygen, acetylene, and combustion supporting oxygen to the raised blowpipe unit. The latter may be separately water-cooled by hose connections 75, 76.

Abstract: 602,869. Ink-ribbon mechanism. STANDARD TELEPHONES & CABLES, Ltd. (International Standard Electric Corporation). Oct. 13, 1944, No. 19789. [Class 100(iv)] [Also in Group XL(b)] In a printing telegraph receiver in which a printing 'tape and inking ribbon are associated with a type-wheel which can be rotated and moved axially to bring the selected character into the printing position (see Group XL(b)) the ribbon P90 is fed to and from rolls P192, P194 carried by ratchet wheels P191, P193, the winding' roll being driven from an arm P155 through a lever P158 carrying a doubleacting pawl member P190. When the ribbon is nearly unwound from one roll, for example, the roll 194, studs on the ribbon are arrested by pins P210, P211 on a member P204 having limited angular motion on a member P202 pivoted at P203. Further winding motion of the ratchet P191 rocks the member P202 clockwise and in this position a shoulder P225 on the double pawl P190 engages the projection P224 on the member P202 when the arm P158 is next operated so that the double pawl is rotated into engagement with the ratchet wheel P193, the operating tooth of the double pawl being shifted to engage with the teeth of the ratchet wheel by a toggle spring P195. A double-acting holding pawl P197 pivotally supported from a fixed plate P198 operates independently by the driving pawl P190 but is provided with a fork P201 which straddles the pin P196 of the pawl P190 so that it is moved with the latter to engage the appropriate ratchet wheel. In a modification, Figs. 7 to 11 (not shown), the printing tape is moved in a direction parallel to the axis of the type-wheel and at right angles to the direction of movement of the inking ribbon. The feed rollers for the inking ribbon are carried by a frame which is resiliently mounted on pivots.
