Title: Improvements relating to control systems for controlled aerofoils of aircraft
IPC: B64C13/00
Filed: 1946-05-06
Abstract: 621,212. Aircraft control systems. PRICE, H. L., and SPERRY GYROSCOPE CO., Ltd. May 6, 1946, Nos. 13705 and 20639. [Class 4] [Also in Group XXXVIII] A strain gauge 58 is employed to measure the strain in the torsion bar spring 22 of an aircraft control system comprising a spring tab 36 and a main control surface 34, and the output from the strain gauge 58 controls a motor 26 to apply a force to the main control surface which is proportional to the strain in the torsion bar 22 and thus to reduce the effort required on the control stick 20. As shown, the motor 26 is also controlled by the output from a strain gauge 66 in the connection to the spring tab 36, and develops an output p 2 X+q 2 Y, where p 2  and q 2  are constants and X and Y are the forces exerted on the main part 34 of the control surface 8 on the spring tab 36 respectively. A further motor 54 operates on a screw connection in the rigid connection to the spring tab and is controlled by the strain gauges 58, 66 to give an output p 1 X+q 1 Y, where p 1  and q 1  are also constant. Preferably, p 1 q 2 =(1-p 2 )(1-q 1 ). A clutch 12 is automatically released to enable manual control if the power supply to the motors 26, 54 fail, and an irreversible connection 38 such as that described in Specification 565,920 may be included in the connection to the spring tab 36. In one form, corresponding to q 1 =1, the motor 54 is of the hydraulic positional follow-up type, and the motor 26 is of the type described in Specification 545,296. Provision is made so that the input to the motors may be provided by an automatic pilot. The motor 54 may have a long-time constant so that it operates mainly to trim the spring tab, and a manual trimming control may be connected to the motor 54 by a flexible shaft 56.

Title: An improved coherent combustible body and process for making same
IPC: C10L5/02
Filed: 1924-06-05
Abstract: 217,236. Frey, W. P. June 5, 1923, [Convention date]. Coking and carbonizing processes and apparatus.-Fuel briquettes are exposed to temperatures sufficiently high structurally to alter the bituminous material, the proportion of which is such as to yield a permanent binder for the mass when a temporary binder has been destroyed or expelled. The heating is effected in a retort in which the briquettes are tumbled and to which the admission of air is restricted, and the temperature is raised from about 1000‹ F. to 1800‹ F. to carbonize successively the binder and the bituminous material. Apparatus described for effecting the processes comprises an inclined rotary drum 2 communicating at its upper end, at which the briquettes are introduced from a shoot 12, with a water-sealed casing 9 and a pipe 10 leading to a suction device and a condenser for treatment and disposal of evolved gases. The lower end of the drum, into which projects a burner 13, enters a casing 14 having water or steam cooling nozzles 15 and a rotary discharge valve 17 which prevents ingress of air. The drum may be heated by solid, liquid or gaseous fuel, or electrically : in some cases gases being generated from the material may be utilized, air alone then being admitted through the burner 13. By the evolution of gases from the briquettes channels are formed therein which become coated with tarry or pitchy matter as the briquettes pass towards the hotter end of the drum.

Filed: 1926-06-03
Abstract: 275,755. Booth, T. H. June 3, 1926. Ironing seams; feeding and damping arrangements and work supports for ironing presses.- The garments are placed upon the horizontal portion 13<x> of the work support 13 and are fed to the iron 50 by a roller 16 in the frame 4 coacting with the surface having the larger radius of a cam 96 having two semicircular concentric surfaces. The cam-shaft 29 is journaled in a weighted lever frame 33 pivoted at 32 and normally is in gear with the drive shaft 24 but can be raised out of gear as shown to interrupt the feed, by operation of a pedal acting through a linkage 91, 35. The iron is carried by a counterweighted lever frame 42 pivoted at 32 and intermittently raised and lowered by a cam 77 coacting with a roller 76 which acts on a lever 61 engaging a stop 60 on a depending rod 59. The frame 71 carrying the roller 76 can be swung counterclockwise to move the roller out of the path of the cam, thereby permitting the counterweight 47 to maintain the iron out of contact with the work even when the drive shaft is rotating. The swinging of the frame 71 is effected by a second pedal and the frame is linked to the linkage 35 so that actuation of the second pedal simultaneously raises the feeding mechanism also. Means for steaming or damping the work before ironing may be provided.

Abstract: 584,950. Delivering thread. AMERICAN VISCOSE CORPORATION. July 24, 1944, No. 14081. Convention date, July 29, 1943, [Class 120 (ii)] Reel mechanism for the delivery and treatment of thread &c. comprises a set of spaced bars rotatably mounted as a unit, a second set of spaced bars alternating with those of the first set, supporting means for the second set rotatably mounted on an axis eccentric to the axis of the first set, the bars of the second set being axially slidable with respect to the supporting means therefor, means for imparting relative rotation between the bars and the eccentric axis, means for imparting axial motion to a part of the bars of the second set with respect to the first set at predetermined intervals in their relative rotation and resilient means for controlling said axial motion. The bars of the first set 2 are carried by members 4, 5 rotatable on bearings 8 on the shaft 7 which carries end caps 9 with non-circular ends engaging in hangers 10 so to prevent the shaft 7 from rotating. The members 4, 5 are rotated by gearing 33, 34. The bars of the second set 3 are formed in three groups and carried by spiders 19, 20 rotatable with a bushing 25 on an eccentric portion 30 of the shaft 7. The bars 3 of each group are also reciprocated longitudinally by a stationary cam 24, through a roller 22, being returned by a compression spring 21. Flexible sealing membranes 31, 32 may be fitted to prevent treating fluid from entering'the working parts. The cam 24 and eccentric portion 30 are so arranged that the bars 3 are projected beyond the bars 2 when the longitudinal reciprocation takes place. In the modification of Fig. 4, the shaft 45 is rotated by a gear 46 to rotate the bars 42. The intermediate bars 43 formed in segments 8 carried by a spider 53, rotate about an eccentric bushing 56 and are reciprocated longitudinally by a stationary cam 50, through a roller 65, being returned by a spring 63. In a further modification, each bar 30 and 43 may be separately mounted and provided with a cam follower. The arrangement of Fig. 1 may be further modified by driving the shaft 7 so that by differential rotation between the shaft 7 and the bars 2 the frequency of operation of the bars 3 may be varied.

Title: Improvements in or relating to method of and apparatus for transmitting longitudinal waves into an object
IPC: G01N29/28
Filed: 1949-05-26
Abstract: 666,521. Supersonic inspection apparatus. SPERRY PRODUCTS, Inc. May 26, 1949. [July 7, 1948] No. 14108/49. Class 118 (ii). In a supersonic-inspection device wherein longitudinal waves in the form of pulsed wavetrains are transmitted into a work-piece 10, and echoes from flaws such as D are displayed on a cathode-ray tube 20, a delay device 16 comprising a wedge of methyl methacrylate is interposed between the piezo-electric transducer 12, comprising a Y-cut quartz crystal producing shear waves, and the surface of the work-piece 10. The sloping surface of the wedge is cut at such an angle to the surface of the work-piece 10 that the shear waves incident thereon from the transducer 12 are reflected as longitudinal waves into the work-piece 10. The delay device is used to enable echoes of flaws close to the surface to be distinguished on the display from the response due to the transmitted pulse. By coupling the delay device to the work-piece through an oil film the reflection at the common surface is small compared with that obtained with metal delay members ; however, it is stated to be difficult to transmit longitudinal waves into the plastic material with adequate power so that it becomes necessary to employ shear waves as described.
