Title: Improvements in or relating to apparatus for reproducing or repeating the movement of a moving object
IPC: G09F9/00
Filed: 1936-06-29
Abstract: 457,601. Electric signalling systems. TOLNAI, G. K., 14, De Geersgatan, Stockholm. June 29, 1936, Nos. 18036 and 26289. Convention dates, June 29, 1935 and June 15, 1936. [Class 40 (i)] [See also Groups XIX and XX] In a system for optically reproducing sporting events such as races, pointing devices such as telescopes are made to follow the runners and they thus control marking members at a remote point to cause them to move over an indicating screen or a model track at corresponding speeds. Timing devices at the remote stations may be started with the runners and stopped as each runner passes the post. As described a number of telescopes 80, 81, 82, Fig. 5, are mounted at 14, Fig. 1, and are driven by motor 83 at a fundamental speed which would enable an observer to follow a runner running at a predetermined speed around the track 11. Operators, one for each telescope, keep the telescopes pointing at their individual runners by means of the handles 59, affecting the movement of the telescope through differential gear. The observer maintains his telescope so that his runner is on a cross line provided on the telescope eyepiece, the cross line being rotated automatically as the telescope is moved so that the line is always at right angles to the track. At the receiving station a model of the track may be provided as indicated in Fig. 4, and marking members 17, 18, 19 are moved around the track under control of the telescopes. Markers 21, 22 and 23, which move with markers 17, 18, 19 indicate the number of laps covered. The markers are normally driven at a rate corresponding to the basic movement of the telescopes and are moved on by impulses received from the transmitting station as the telescopes are speeded up by means of the handles 59. A stop clock 25 may be started as the runners start and be stopped when the first runner crosses the finishing line. Instead of moving markers along a track, the telescopes may control marking points projected on a screen. The film 113, Fig. 11, represents the track and is made to move from right to left on the screen at a speed corresponding to the fundamental speed of the telescopes. Metal strips 118 each having a single perforation are moved from left to right by the impulses generated by the handles 59. The effect given is of dots 124, Figs. 12 and 13, moving rapidly along a track, lines marking distances being shown on the screen to give the moving effect. Individual time films 122 show on the screen the time taken by the runners, the films being stopped as each runner passes the post. The impulses transmitted may be recorded so that a representation of the race may be reproduced at any time.

Abstract: 559,139. Making taps, drills, reamers &c. COVENTRY GAUGE & TOOL CO., Ltd., HARLEY, H. H., and WAINWRIGHT, J. E. Dec. 21, 1942, No. 18094. [Classes 83 (ii) and 83 (iii)] [Also in Group XXIII] In the manufacture of screwcutting taps and like tools such as drills and reamers, the screw-cutting and/or relieving operation is performed prior to the formation of the flutes or subsequently thereto, the cutter in the latter case being rotated in the reverse direction to that usually adopted so that cut!ing finishes at the cutting edge instead of starting there. The invention is particularly applicable to taps of “ in. diameter or less. The tap is cut or ground with alternate high portions b and low portions c by periodically varying the pressure between the work and cutter or wheel. The shank of the cutter is provided with a flat and the high spots are so correlated to this flat that when flutes f are cut using the same location, the cutting edges h are correctly located as shown.

Title: Improvements in and relating to television
IPC: H04N5/217
Filed: 1935-06-24
Abstract: 462,110. Television transmitters. WHITE, E. L. C. June 24, 1935, No. 18099. [Class 40 (iii)] The picture received from an " iconoscope " transmitter or a transmitter of the type disclosed in Specification 442,666 is found to possess an uneven shading due to the presence of spurious signals. This defect is overcome by mixing with the picture signals a correcting signal comprising integrations of the saw-tooth scanning oscillations. A simple integrating circuit comprises a resistance R, Fig. 1, and condenser C, the integrated signal being taken off from condenser C. The second integration may be added, being obtained by subjecting the first integration to a second circuit such as that of Fig. 1 and Fig. 2, (not shown). The correcting signal may also include a saw tooth scanning oscillation component, the input of Fig. 1 being fed from a potentiometer, Fig. 3 (not shown). In a more complex circuit, the saw-tooth oscillation is fed to the grid of valve 6, the condenser 12 and resistance 8 acting as an integrating circuit, and the integrated wave is amplified by valve 13. The valve 13 may be operated so that its cathode potential follows its grid potential by connecting a condenser between its cathode and the junction of resistance 8 and a second resistance in the anode circuit of valve 6, Fig. 5 (not shown). This arrangement enables a more accurate integration to be performed. Specification 463,967 is referred to.

Title: Improvements relating to self-priming centrifugal pumps
IPC: F04D9/02
Filed: 1932-06-28
Abstract: 386,232. Centrifugal pumps. SCHULE, H. F. W. and GREVE, K. H., (trading as SCHULE & CO., F. W.), 16, Spitalerstrasse, Hamburg, Germany. June 28, 1932, No. 18243. Convention date, Oct. 22, 1931. [Class 110 (i).] A self-priming cen. trifugal pump has an impeller 7 in a casing 1 with a suction branch extending from the impeller eye 15 upwards to the top level of the casing. The wall of the casing closely follows the impeller circumference between the points 3, 10 so that at least one impeller channel is overlapped. The impeller projects into the discharge space so that a line 14 extended from the inner wall 6 of the delivery branch intersects the impeller as a chord. The arrangement of the suction branch enables water to be retained in the pump when it stops working. On the pump restarting, the water is thrown into the extended delivery space 2, 13 thus sealing the pump against the back flow of atmospheric air. The air pressure in the pump and the suction branch is consequently diminished. As the impeller blades travel up to the point 3, they collect water form the discharge chamber which partly fills the channels 11, 12 under the casing wall between the points 3, 10. After the blades pass the point 10 the water is thrown outwards and air is drawn in from the suction opening to escape through the water column in the delivery space 2. This action is repeated until water is drawn into the suction opening.

Abstract: 1,183,281. Controlling steelmaking processes. CENTRE NATIONAL DE RECHERCHES METALLURGIQUES. April 18, 1968 [April 18, 19671, No. 18314/68. Heading C7D. In a converter steelmaking process the intensity of radiation from the flame is monitored and from that intensity there is calculated the instantaneous value of decarburization rate; the refining conditions are then modified so that the decarburization rate follows a predetermined curve. The process may be varied by integrating the instantaneous values of decarburizing rate against time, and plotting the resultant value of carbon eliminated, this curve being compared against a predetermined control curve and any deviation reduced by varying the refining conditions. Corrections may be applied to the measured value, or the parameters deduced therefrom, to compensate for the effect of lime additions or of foaming slag. In a preferred embodiment of the invention it is the luminous energy of the flame which is measured.
