Title: Improvements in or relating to cleaning devices for yarn or the like
IPC: B65H63/06
Filed: 1926-12-21
Abstract: 272,437. Universal Winding Co., (Assignees of Beckman, G. S.). June 8, 1926, [Convention date]. Clearing-apparatus; thread-guides; tension-arrangements; stop-motions. - A device for clearyarns comprises a member 30, Figs. 1 and 3, having a clearing-aperture and mounted to be oscillated by the swaying movement of the yarn y as it is drawn through the device, the member being pivotally mounted about an axis substantially parallel to the path of the yarn. The clearer 30 comprises two members 40, 41, Figs. 5 and 6, the clearing slit being formed by the arms 48, 56, the members 40, 41 being relatively adjustable and secured together by the screw 59. The edges 48, 56 are notched at their lower ends to form an opening 61 for the escape of lint &c., while the device is mounted on a rod 31 and adapted to rock at right angles thereto, its motion being limited by stops 53. 55 contacting with the arm 35 of the rod 31. The yarn passes through a tension device 10 of the type described in Specification 204,777, having guide fingers 23, 24 and coacting discs 14, 15 weighted at 27, through the clearer 30, under the cross-rod 65 of a stop-motion drop-wire 62 and thence to the thread-guide 4. As the guide traverses to wind the yarn package, the clearer is rocked on its axis 31, the yarn thereby moving up-and-down the clearing-slit while the blows of the lugs 53, 55 on the stop 35 dislodge any dirt &c. removed. The wire 62 forms part of an ordinary stop-motion and drops when the yarn breaks or exhausts to stop the machine. The stop 36 prevents it being lifted by the yarn.
Patent GB-623214-A (GB)
Title: Remote control installation
IPC: H04Q9/04
Filed: 1946-10-31
Abstract: 623,214. Electric control systems. COMPAGNIE ELECTRO-MECANIQUE. Oct. 31, 1946, No. 32377. Convention date, Sept. 20, 1945. Addition to 620,710. [Class 40 (i)] The system of the parent Specification, in which synchronous distributers at the transmitter and receiver are released for rotation by a circuit including a synchronizing contact on each, is modified in that the order signal is only effective if a test circuit over a synchronism checking contact is satisfactory. In one embodiment, the transmitting distributer 3 and receiving distributer 20 have synchronizing contacts 5, 22 through which the distributers are released and synchronized as in the parent Specification. When the rotor arms reach the contacts 8, 29 appropriate to the controlling switch 10 and corresponding controlled circuitbreaker D respectively, a circuit is completed thereby through relay 9, switch 10, rectifier 11 or 12, battery 32 or 34 and relay 31 or 33. Switch 30 is connected mechanically to move with the circuit-breaker and, if its position does not correspond with the setting of switch 10, a current flows from either battery 32, 34 according to the connected rectifier 11, 12 and energizes relay 9, thereby causing lamp 15 to indicate the disagreement. Contact 14 is now closed by the operator to short-circuit relay 9 and pass sufficient current to operate the appropriate relay 31, 33 which locks over contact 36, 37. When the distributer arms reach the synchronism checking contacts 17, 26, current flows from battery 18, through these contacts, to relay 27, which completes a circuit from battery S through contacts 38 or 39 of the operated relay 31 or 33 and the appropriate winding 41 or 42 of the circuit-breaker D. The movement of the breaker changes switch 30 to its alternative position in which condition no current can flow through relay 9 as the connected rectifier 11, 12 is poled oppositely to the battery 32, 34 now in circuit. Thus, the actual change-over of the equipment is only effected if a circuit is completed over contacts 17, 26 to relay 27 and consequently cannot take place if synchronism is lost. In a modification of the foregoing, the battery 18 is replaced by a condenser charged by battery 16 through a relay operated over the distributer 3 and discharged through the synchronism checking contact 17 to give the checking signal. It is also possible to use only one relay 9 irrespective of the number of controlled devices bv the use of two additional distributer banks at the transmitter which connect the appropriate signal lamps and operating switches in turn to the relay (see Fig. 2 (not shown). It is also proposed to signal by alternating current using one frequency for synchronizing, another for synchronism checking and one each for the two conditions of the controlled equipment. In such an arrangement only one oscillation generator is used, its frequency being changed by switching in additional capacities by polarized non-linear resistance elements (see Fig. 4, not shown).

Title: High temperature coking of residua
IPC: C10G9/30
Filed: 1957-10-22
Abstract: Heavy oils are coked in a fluidized system by contacting the oils with fluidized particulate solids at above 1200 DEG  F. to produce a vaporous product and a carbonaceous residue which is deposited on the particulate solids, separating the solids from the vaporous product, separating the vaporous product after quenching to obtain at least a naphtha product, a light gas oil fraction boiling below 650 DEG  F., and a tar bottoms having an initial boiling point contiguous to the final boiling point of the light gas oil fraction, stripping from the tar bottoms an overhead fraction having a final boiling point below 800 DEG  F. and condensing and combining the overhead fraction with a portion of the light gas oil fraction to obtain the liquid quench medium. In a typical example a feed comprising an 1100 DEG  F. I.B.P. South Louisiana residuum is fed through a pipe into a transfer line zone, the temperature of which is 1400 DEG  F.  After approximately 0.75 sec. the reaction mixture is quenched by a liquid medium added through a line, the temperature after quench being 500 DEG  F. The quench vapours are separated to obtain 26.8 per cent by weight of naphtha boiling below 430 DEG  F., a gas oil fraction boiling from 430 DEG  F. to 650 DEG  F., and a heavy tar bottoms which is stripped with steam to remove a 650-700 DEG  F. fraction which is combined with a larger quantity of the light gas oil fraction which is recycled to the quench point at a temperature of 240 DEG  F. as a quench medium.  The remainder of the light gas oil fraction amounting to 7.6 per cent by weight on the fresh feed, and of the stripped tar bottoms amounting to 30 per cent by weight are withdrawn as products.
