Title: Improvements in and relating to time indicating devices and particularly motor driven clocks
IPC: G04B19/21
Filed: 1934-09-25
Abstract: 426,250. Clocks. GREENAWALT, F. A., 104, Pennfield Court, Pittsburg, U.S.A. Sept. 26, 1934, No. 27478. [Class 139] [See also Group XIX] In a clock, the time-indicating means consists of rotatable drums 45, 47, 49 each with a different number (ten, six, and twelve) of flat faces of equal peripheral length and having numerals thereon to represent the time, one face of one drum being co-planar with one face of each of the other drums, and interacting lugs 89, 91, (or 93, 95), on the inner surfaces of the drums whereby a drum (e.g. 47) is periodically (every ten minutes) advanced one step by the next lower drum (45). The interacting lugs (e.g. 89, 91) on any two coacting drums 45, 47 move through paths of different radii which substantially coincide only for a distance equal to the length of a numeral face. The synchronous electric motor 31 drives a disc 69 one revolution a minute and the single tooth 71 on this disc coacts with a ten-toothed wheel 73 rigid with the ten-faced minute drum 45 so as to rotate this drum one face each minute. The drums 45, 47, 49 are of different diameter and have their three aligned faces, which show at window 23, in one plane. Once during each revolution of the drum 45 a lug 89 on it, Figs. 3 and 9, meets one of six lugs 91 on the six-faced drum 47 which shows the tens of minutes and turns this drum one face. Similarly, once each rotation of drum 47, a lug 93 on it, Figs. 3 and 12, meets one of twelve lugs 95 on the hour drum 49 and turns this drum one face. The pivot shafts 57, 59, 61 upon which the hubs respectively 51, 54, 55 of the drums 45, 47, 49 rotate freely, are held in springy uprights 35, 37, 39, 41 of which 37 and 39 are bifurcations of a single member 43. These uprights are forced apart to insert the shafts which have reduced ends and are of such length that they are held against rotation by the axial pressure of the uprights. The hubs 51 &c. are slightly shorter axially than the unreduced parts of shafts 57 &c., to allow of free rotation. The hour and minute numerals are marked on metal strips which are detachably secured to the drums. Electric clocks.-A rotating knurled disc 107 in the train from motor 31 to disc 69 is visible in the front of the clock and indicates whether the motor is running. Also if the clock has stopped, the window panel may be removed by means of tab 121, Fig. 1, and a sharp rotation may be given by hand to the disc 107 to restart the motor. Time - setting.-The window panel may similarly be removed to allow the drums 45, 47, 49 to be manually and individually rotated until they show the correct time. Cases, clock.-The bezel 109 is a hollow frame and its holding screws 115 also hold in position a sheet 111 which has a sight opening 113 just large enough to expose the three aligned drum faces and which is curved at each side of this opening to define sharply the three exposed faces. A glass 117 and its holding frame 119 are removably held in the bezel 109 and may be readily taken out by means of tab 121.

Abstract: 350,350. Control of A.C. motors. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitõts Ges.; 2, Friedrich Karl-Ufer, Berlin.) Sept. 19, 1930, No. 28093. Convention date, Sept. 19, 1929. [Class 38 (iii).] Regenerative and non-regenerative braking.-Highspeed motors supplied through a frequency increaser, and used for example for driving a woodworking machine, are stopped by disconnecting them from the frequency increaser, and connecting them to a braking current source. As shown in the Figure, when a switch 5 is closed and the frequency increaser 3a is running, a coil 6a of a switch 6 is energized, and the switch is closed. By pressing one of each set of pushbuttons 14d, 15d, 16d in turn, switches 17, 18,19 are closed, and the motors 14, 15, 16 supplied from the frequency increaser. To stop the drive, one of a set of pushbuttons 11 is pressed, thus de-energizing and opening the switch 6, the normally closed contacts 6s of which complete a circuit for the coil 7a of a switch 7 which closes to connect the motors to the same supply as that from which the frequency increaser is supplied, the connections being such as to "plug" the motors. The switch 7 may act in two stages, first to connect the motors for the same direction of rotation, and then to make reverse connections. The current source to which the motors are connected may be of any frequency, and may be a separate source, either D.C. or A.C. A variable resistance 10 is connected between the motors and their brake current source.

Title: Improvements in wireless apparatus and process for determining the position of a moving object
IPC: G01S1/02
Filed: 1935-10-11
Abstract: 457,681. Electric signalling systems. MARIQUE, J., 36, Avenue Brunard, Uccle, and SOC. ANON. INTERNATIONALE DE TELEGRAPHIE SANS FIL., 13, Rue de BrÚderode, both in Brussels. Oct. 11, 1935, No. 28156. Convention date, Jan. 24. [Class 40 (i)] [See also Group XL] The course of a moving craft, such as a ship 26, Fig. 1, navigating the fairway 27 of a harbour, is continuously plotted on a chart by co-ordinating the bearings of two or more land beacons 24, 26 by means of direct reading radiogoniometers 45, 46 fitted with luminous rotating indicators operated at such speed as to give a persistent visual effect. Since the ordinary point of intersection 48 of the two readings would not " follow the path of the ship, it is necessary to apply a correcting angle # which is the difference between the constantly varying angle # made by the line joining the two radiogoniometers 45, 46 with geographical North 60 and an angle gamma representing the fixed inclination of the line joining the two land beacons 24, 25 to North. Fig. 2 shows one means for applying this correction. A frame aerial 2 is driven at a constant speed by a motor 14, which also drives the rotating parts 5, 5<1> of a luminous recording device of the kind described in Specifications 380,385 and 447,238, [both in Group XL]. These produce two bearing lines intersecting at a point. In order to make this point correspond with the point 48, Fig. 1, and so record the actual position of the ship on the chart 20 of the harbour entrance, the previouslymentioned corrective angle # is applied from the compass or gyrocompass 13 through a repeater 12 to a differential gear 9 inserted in the driving-shaft 62 of the frame aerial. The second correcting angle y, which is of course fixed for any given harbour, is applied by making an initial adjustment in a variable coupling 7, inserted in the same shaft. Bearings may be taken on three land beacons for difficult fairways. The land beacons may be energized for alternate periods of time on the same wave length, instead of being simultaneously energized. The variable correcting- angle # may be applied by rotating the stator of one of two synchronous driving-motors through gearing controlled by the ship's compass, to which a preliminary adjustment representing the " fixed " correcting-angle gamma is also applied. To facilitate observation by the navigating officer of the course of the vessel auxiliary indicators 50, Fig. 9, may be used in conjunction with the chart 20 so that the position of a mark 52 relative to the line 54, 53 shows the deviation of the vessel from its proper course. The Specification as open to inspection under Sect. 91 comprises also an arrangement in which the frame aerial 2 shown in Fig. 2, and the associated driving gear, is duplicated, and bearings are taken on two beacon stations transmitting on different wavelengths. This subject-matter does not appear in the Specification as accepted.

Filed: 1969-06-04
Abstract: 1278659 Colour projection: diffraction gratings AGFA-GEVAERT A G 4 June 1969 [4 June 1968] 28352/69 Heading G2J In the photographic recording of a colour image of an object on a black-and-white photo-sensitive layer, an image of the object is projected on to the layer by an objective and also images of colour selective filters 4b-4e located in the objective plane are projected as diffraction gratings, e.g. 5, 6, 7, on to the said layer by a lenticular screen 3, the filters 4b-4e being of different widths and/or relative angular positions and having different grid constants and/or azimuth angles for the different colours. As the grids are thus related to orders of diffraction reproduction of the coloured image from the black-and-white layer is achieved by illuminating the layer with reference to the desired orders of diffraction. The filter strips 4b-4e of desired widths to give a continuous series of bands are located between the two halves 1a; 1b of the objective. An area 4a on the optic axis corresponding to the zero diffraction order has no filter. Immediately adjacent this area are yellow filters 4b, and moving outwards from the centre on either side respectively red, blue and green filters 4c-4e. They are so arranged that no gaps appear between the areas covered by individual lenslets of lenticular screen 3. If desired the strips may be angled to one another, e.g. green 17, Fig.3, and blue 18 of same width but at right angles, and red 19 at 45‹ to these two but wider by a factor #2. The two outer strips 4e are each of such width that the image of one of them formed on the layer by one lens of the screen 3 coincides with the image of the other of the outer strips 4e. If the lenticular screen 3 is cylindrical the transmission factor of these strips 4e is half that of the other strips. Alternatively the images of strips 4e may abut. The screen may also comprise spherical lenses. The reproduction of coloured images is as described in Specification 1267861. In an alternative embodiment there is formed on the layer superimposed black-and-white images of a plurality of objects. In this embodiment the colour-selective filter is replaced by a slit the width and/or azimuthal angle of which is arranged to be adjusted between successive exposures, or is arranged to be replaced by another slit of different width and/or azimuthal angle between successive exposures.

Title: Improvements in and relating to processes for the separation of hydrocarbons
Inventor: PALMER KEITH WILLIAM
IPC: C07C7/152
Filed: 1961-08-04
Abstract: Styrene is separated from non-olefinic hydrocarbons, e.g. from the product of dehydrogenating ethylbenzene, by absorption in an aqueous solution of a heavy metal fluoborate or fluosilicate; silver is the preferred heavy metal.  In a preferred embodiment the liquid styrene-containing feed is contacted in one or more stages counter-currently with the absorption agent which is thereafter regenerated in two stages.  In the second regeneration stage steam or an immiscible organic solvent is passed counter-current to the solution to strip out styrene part of which is recovered and the other part of which is introduced into the first or purification stage together with steam or an immiscible organic solvent to remove any dissolved non-olefinic hydrocarbons, which are recycled to the absorption stage, by phase exchange.  If butane is used as an immiscible solvent it may be used as liquid in the last stage and a vapour in the purification stage.
