Title: Improvements in or relating to gyroscopic indicating or steering systems
IPC: G01C19/36
Filed: 1945-08-23
Abstract: 662,834. Electric indicating systems. BENDIX AVIATION CORPORATION. Aug. 23, 1945. [Sept. 21, 1944] No. 21624/45. Class 40 (i). [Also in Groups XX and XXXV] In a system for operating a heading indicator or course-controlling device by integrating the rate of turn of an aircraft, ship, &c. the precession torque of a gyro 10 with its spin axis horizontal and transverse to line of flight, etc. is opposed by the torque of an eddy current coupling device 33, 35 driven by an induction motor 28 which runs when precessional movement of the gyro moves the primary of a transformer 22 in relation to its secondary and so cause an output which is amplified and fed to winding 27 of the motor. The motor also drives a pointer 47 which thus registers the change of heading. During straight flight, the induction motor is controlled by the output signal of a selsyn device 50 responsive to an inductor compass of the static type. In the case of an aircraft, the springs 15, 16 permit the precession of the gyro and the pointer 41 indicates the rate of turn. Springs 15, 16 are omitted when the device is employed in a ship and the rate of turn indication is not given. The system is also described as applied to the control of a rudder, as for example, in the automatic steering system described in Specifications 537,514, [Group XXXV], 559,327 572,213, [Group XX], and 662,833, [Group XXXV], are referred to.

Title: Improvements in image recognition method and system
IPC: G06V10/46
Filed: 1961-06-15
Abstract: 929,381. Photo-electric image recognition systems. GENERAL ELECTRIC CO. June 15, 1961 [June 17, 1960], No. 21646/61. Addition to 858,002. Class 40 (3). [Also in Group XIX] In the image recognition system of the parent Specification in which a radiation spot traces the image and the directions of motion of the spot at points separated by a small interval are used to derive a signal characteristic of the image, the signal is made invariant with respect to magnification of the image by making the interval a predetermined fraction of the image perimeter length which is previously measured. When the radiation spot picks up the image a pulse t is derived from the second harmonic filter, Fig. 1 (not shown) which sets the pulse operated gates 112, 114, 106 to the positions shown in Fig. 2. An amplitude control 49 is thus connected to a fixed source of potential 125 and causes the radiation spot to trace out the image at a predetermined rate. An integrator 113 integrates the voltage from a source 121 to give an output which increases with time. Pulse t causes samplers 107, 109 to sample and store the spot co-ordinates at the beginning of the trace and these stored co-ordinates are continuously compared with the instantaneous coordinates of the spot so that when the spot returns to its starting position there is coincidence for both x and y co-ordinates and a coincidence circuit 111 emits a pulse t2 which changes over switches 112 and 106. The output of integrator 113 which is a function of the time taken to trace the image perimeter at the predetermined speed persists and is now connected to the amplitude control 49 so that during the image recognition process the speed of trace is proportional to the image perimeter length, and a fixed time delay corresponds to a predetermined fraction of the perimeter. When recognition has occurred a pulse t3 closes switch 114 to discharge the integrator and prepare the system for the next recognition. Specifications 837,341 and 873,156 also are referred to.

Title: Improvements in the manufacture of transparent sheets or coatings
IPC: C08L89/00
Filed: 1934-07-30
Abstract: Films are prepared by bringing casein into aqueous solution of such high concentration and viscosity that the mineral salts and other impurities become insoluble therein, filtering the solution, treating with a deficiency of a setting agent, coating a base with the solution, and drying the coating.  A suitable concentration for the solution is 15 per cent.  The viscosity of this solution may be made about the same as that of glycerine, e.g. by adding alkali until the pH value is about 7,2.  In order to prevent deterioration by fermentation, the temperature of the solution is preferably kept at about 71 DEG  C.  Plasticizers, such as glycerine and sulphonated castor oil may be added.  The setting agent, e.g. formaldehyde, hexamethylenetetramine, trioxymethylene, aldehydes, chromium salts, tannic acid, or acetone, may be added to the solution, or the formed layer of casein solution may be passed through a bath containing it. A suitable amount of formaldehyde (40 per cent solution), is 1 per cent of the amount of casein solution treated.  The film produced may be rendered moisture proof by coating with a cellulose lacquer.  The process may be applied to the coating of foils or sheets of other materials with casein.
