Title: Improvements relating to gelatine coating compositions and materials coated therewith
IPC: G03C1/76
Filed: 1941-07-29
Abstract: 552,290. Gelatine solutions. KODAK, Ltd. July 29, 1941, No. 9646. Convention date, Aug. 3, 1940. [Class 2 (ii)] [Also in Groups V, VIII and XX] A gelatine solution adapted to form coatings and films for photographic and other purposes with reduced setting time and absence of tendency to form air bubbles comprises a 3 to 10 per cent. aqueous gelatine solution containing a water-soluble methyl cellulose of methoxy content from 16 to 28 per cent. in a quantity from ¢ to 20 per cent. of the weight of the gelatine. In preferred proportions, the solution contains from 5 to 20 per cent. of methyl cellulose calculated on the weight of the gelatine, but if special clarity of coating is desired the quantity of methyl cellulose is preferably smaller, e.g. from 0.5 to 2 per cent. The composition is preferably made up at a raised temperature, e.g. 100-120‹F., and applied warm. The composition adheres well to cellulose ester photographic film, and is useful when a warm aqueous gelatine solution is to be applied as an overcoating to a wet, chilled photographic emulsion layer. The composition may be used as a photographic backing or overcoating composition, or for photographic emulsions.

Title: Improvements in or relating to means for controlling winding engines for mines
IPC: B66B5/02
Filed: 1922-04-04
Abstract: 178,115. Siemens - Schuckertwerke Ges. April 5, 1921, [Convention date]. Lift cages, operating.-Winding engines for mines are controlled by means which retard the speed of the descending cage automatically when it approaches keps or stops which are in the set or arresting position to stop the cage, such means being independent of the means for checking the speed and preventing overwinding of the ascending cage. Fig. 1 shows a mechanism in which three sets of keps or stops I, II, III are linked to a common rod so that a downward axial movement of the rod withdraws them from their acting positions in succession. The movement of the rod is performed by the movement of a hand-lever 6 which simultaneously moves a shaft axially to bring a crank 11 into register with one or other of three snail cams 1, 2, 3, one cam corresponding to each set of keps. The cam shaft is driven from the shaft carrying the depth indicator 14, and the cams are set to actuate the crank at various times and bring the main controlling-handle 5 back to neutral position. For example, if it is desired to stop the cage at level II, the keps rod is lowered sufficiently to withdraw the keps I only. This brings the crank II in register with cam 2, which is set to actuate the controlling handle at such a time that the cage will come to rest gently on the keps II. To prevent the keps being altered in position during the progress of the descending cage, the crank shaft may slide through a fixed guide which prevents axial movement of the shaft except when the handle 5 is in the neutral position. A slightly modified means for connecting the keps to the actuating rod is described. The Specification also describes electrical means for controlling the keps and a further arresting device dependent upon the level of the water in the sump at the bottom of the shaft so that the cage shall be arrested before reaching the water. In this construction an auxiliary motor operates a sliding bar moving over a series of bar contacts of a switch in electrical connection with the various arresting devices, and also operates a second sliding member which contacts with the depth indicator to actuate and centralize the main controller handle.

Title: Improvements relating to the reduction of primary spherical aberration in magnetic electron lenses
Inventor: LIEBMANN GERHARD
IPC: H01J37/145
Filed: 1947-04-12
Abstract: 665,094. Electron lenses. ASSOCIATED ELECTRICAL INDUSTRIES, Ltd. April 12, 1948 [April 12, 1947], No. 9775/47. Class 39 (i). The primary spherical aberration caused by a converging magnetic electron lens is compensated by combining therewith a diverging electrostatic. lens of which the marginal focal length is smaller than the paraxial focal length; the electrostatic lens is formed by a plane electron permeable metal film 6, Fig. 1. and a cylinder 4, the cylinder 4 forming one of the pole pieces of the magnetic lens, and the metal film 6 being mounted on the other pole-piece 3, as shown. 5 is a brass spacer and sleeve 8 insulates member 4 from shroud 2. Fluctuations in accelerating voltage can be made to appear also between electrodes 4, 6 and the resulting fluctuations in the focal length of the electrostatic lens can be made to compensate for the corresponding fluctuations in focal length of the magnetic lens. Alternatively, two electrostatic correcting lenses may be used. one correcting spherical aberration and the other correcting chromatic aberration due to voltage fluctuations. In a modified construction, Fig. 2 (not shown), the objective and projector lens of an electron microscope each comprise a combined magnetic and electrostatic lens. The metal films used may be of aluminium or beryllium evaporated on to a thin plastic film, or may be stretched tightly over a suitable frame. The invention is applicable to high voltage cathode-ray tubes, electron microscopes, and to fine focus X-ray tubes. The magnetic lens be operated as described in Specification 665,111. The Provisional Specification refers in addition to ion optical lens systems and states that the metal film may be curved.

Abstract: PURPOSE:To improve the recognizing accuracy and to deal with the attenuation and the disturbance of signals with a coordinate input device by detecting the vibration phase difference of a vibration sensor and the sine wave vibration of a vibration pen and recognizing the coordinates, with use of plural cycles of the sine wave vibrations. CONSTITUTION:The sine wave vibration of a certain fixed frequency is produced by a vibration pen 3 and sent to an arithmetic/control circuit 1 after the waveform phase is measured by a signal phase measuring circuit 9. The circuit 1 stores the frequency and the phase of the pen 3. The another frequency is produced and its phase is measured. These operations are repeated by several times for calculation of the distance set between the pen 3 and a vibration sensor 6. Meanwhile the circuit 9 amplifies the signal of a drive signal producing circuit 12 and the signal of the sensor 6 and then applies the filter processing and the A/D conversion to these signals. Then the circuit 9 detects the A/D conversion data or an ultrasonic signal of the sensor 6 and then samples and holds it for execution of the Fourier transformation. Thus the circuit 9 detects the phase difference between the sine wave vibration of the pen 3 and the vibration of the sensor 6.

Abstract: PURPOSE:To provide a method for calibrating the recognition optical system of a visual recognition device which can stably obtain a calibration value which is a conversion constant for converting the minimum resolution unit in the coordinate space within a vision controller such as an electronic parts packaging device to an actual distance. CONSTITUTION:A CCD camera 4 moves to above a recognition mark 2 provided on a substrate 1, the image of the recognition mark 2 is taken into a vision controller 5, and then the center of gravity of the recognition mark 2 is detected. After that, the CCD camera 4 is moved in Y direction by a certain distance using an X-Y robot 8 so that the recognition mark 2 does not deviate from the inside of the visual field of the CCD camera 4 and then the center of gravity of the recognition mark 2 is detected again. As a result, a calibration value is calculated from the distance in memory space of the vision controller 5 between the two obtained centers of gravity and the traveling distance of the actual X-Y robot 8.
