Title: Television apparatus suitable for video signal analysis
IPC: G09G1/00
Filed: 1975-03-27
Abstract: 1504809 Cathode-ray tube circuits; television PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 27 March 1975 [1 April 1974) 12919/75 Headings H4T and H4F In order to analyse the shape of an object O, Fig. 1, whose image size on a vidicon pick up target TP is smaller than the width of a scanned line 7, the entire raster is shifted by a fraction of that width, in the field scan direction, between each successive frame. The signal resulting from the selected scan line 5 in each successive frame is displayed on an oscilloscope having a long persistence screen. Successive displayed lines are displaced vertically and horizontally upon the oscilloscope screen to facilitate analysis Fig. 7. The shifting of the raster between frames is effected by superimposing a stepped signal upon the sawtooth waveform driving the field deflection circuit of the vidicons beam, each step lasting for one frame scan period equivalent to the two interlaced field scan periods. The device may be used for analysis of faults in an evenly illuminated target or for analysis of elements of a viewed scene. The scan line required for analysis is selected by an adjustable multivibrator circuit. Associated timing circuitry controls the sampling of the relevant video signal issuing from the pick up. Instead of being displayed on an oscilloscope the sampled video may be stored for subsequent output in printed form on a device incorporating a laser beam which burns away a metal foil surface. Alternatively digital processing of the sampled video may be performed.

Abstract: 140,652. Nielsen, H. J. May 22, 1919. Pendulum governors for marine engines. Fig. 3 shows a governor supported on a plate 3 running longitudinally of the vessel. The pendulum 4 swings on a pivot 6 in a guide 12 and is hinged at 8 so that, as the vessel rolls, the lower part can swing without straining the pivot. The weight is adjustable by means of a screw 10. As the vessel pitches and raises the propeller, the pendulum moves radially to the left, and the pawl 13, bearing against a part 17, swings the lever 18 and, by means of the toothed gear shown, rotates the spindle 35 and closes the throttle valve. As the vessel returns to a level keel, the piston 44, moving in a cylinder open at one end to the condenser and at the other to the atmosphere, returns the lever 18 and opens the valve. When the vessel has pitched to a predetermined angle the adjustable trip-piece 21 raises the pawl out of contact with the piece 17, allowing the piston to operate as described above and open the throttle valve, so that the engine is running at the normal speed when the vessel is again on a level keel.

Title: Improved egg product
IPC: A23L15/00
Filed: 1943-08-11
Abstract: Egg white is ripened in the presence of an acid-reacting phosphate or a dilute mineral acid until the pH is from 6.3-6.5 and then evaporated at a temperature just below the coagulating point of 130 DEG  F. to a syrupy consistency.  The phosphate or acid shortens the ripening process of fresh egg white to about four days so that the beating properties are improved prior to the development of unpleasant odours.  If the egg white is not fresh, the process may be further shortened.  A small proportion of an edible colloid or glycerine may be added prior to evaporation. The product, mixed if so desired with egg yolk, may be preserved by depressing its temperature to just above freezing point or by freezing it.  In an example, 100 parts by weight of egg white are ripened in the presence of 1 part of sodium acid pyrophosphate until the pH is 6.4, 4 parts of glycerine and, if desired, 1/2 -3 parts of carob gum or gum tragacanth, are added, and the mixture is evaporated until it is reduced to 25 parts. The Provisional Specification comprises also the addition of the phosphate or acid after the natural ripening of the egg white until the pH is from 6.2-6.6, particularly 6.4.  Glycerine may be added at the same time and colloid after evaporation. Specification 543,680 is referred to.

Abstract: 1360706 Glass fibre manufacture SAINTGOBAIN 20 March 1972 [7 April 1971] 13002/72 Heading C1M In the manufacture of glass fibres in which molten glass 10 is fed to a hollow centrifuge 1 having a vertical axis of rotation and which has a peripheral wall 3 with rows of fine apertures 4, the molten glass 10 is caused to flow within the centrifuge 1 in the form of an annular sheet on the surface of an annular member 5 which is disposed concentrically of the axis, is rigidly connected to or integral with the wall 3 at a level lower than the apertures 4 and is disposed in a plane substantially perpendicular to the axis so that, in use, the molten glass flows from the annular member 5 upwardly over the inner face of the peripheral wall 3. As shown in Fig. 1, the molten glass stream 10 passes centrally through the hollow shaft 2 on which the centrifuge 1 is mounted, and which is heated at 19, to a centrifugal distributer 8 with apertures 9 which projects the glass on to the member 5 from which it flows up wall 3 to be ejected as fine filaments from the apertures 4. The temperature of the member 5 may be maintained only by the molten glass 10 or an induction heater 18 may be provided, the temperature gradient in the radial direction being small. The filaments are then attenuated by a gas blast from a slot 11 from combustion chamber 12 and an annular jet of hot air or steam from a blower 14 may also be provided, together with a shield (17, Fig. 5) surrounding the centrifuge 1 at the level of the apertures 4. The size of the apertures 4 may decrease from the upper part of the wall 3 to the lower part to maintain the size of the filaments equal. This embodiment may also incorporate a reserve annular chamber 7 as in Fig. 4, behind wall 3 formed by an inner wall 6 enclosing a refractory material 13. As shown in Fig. 4, the molten glass stream 10 is offset from the axis of rotation of centrifuge 1 and falls on to an annular channel 15 which partly constitutes the member 5. This embodiment shows the reserve chamber 7, but this may be dispensed with. When separate, the member 5 is preferably of the same metal as the wall 3. Specifications 812,657; 833,157 and 997,307 are referred to.

Abstract: 1,255,192. Conveying shrimps. MACHINEFABRIEK B. & S. BEDRIJVEN V. D. WOERDT N.V. 12 March, 1969 [14 March, 1968], No. 13005/69. Heading A2U. [Also in Divisions B2 and B8] Apparatus for sorting shrimps on a conveyer belt 1 comprises a stop with converging walls (7), (8), Fig. 3 (not shown) one of which may be parallel to the direction of conveyance. The downstream end of the stop is open whereby pieces of shrimp and straight shrimps may pass directly through the stop whereas curved shrimp are held by the stop and are released in timed relation upon upward movement of the stop. A plate 11 positioned in the stop ensures that shrimps are released by the stop when it is raised. In a further embodiment, Fig. 4 (not shown) a gripper (20), (22) is positioned upstream of the stop and a rotary brush 27 with a peripheral recess 28 is located downstream of the stop. The recess 28 is synchronised with the gripper such that pieces of shrimp, straight shrimps and incorrectly orientated shrimps, i.e. shrimps travelling head first which advance into the stop beyond the reach of the gripper, are brushed from the conveyer whereas those shrimps which are correctly orientated, i.e. heads trailing, are received in the stop and then gripped by the gripper to be released when the stop is raised and in timed relation with the recess 28 to pass through said recess. In a further embodiment, Fig. 6 (not shown) two stops (44), (45) are mounted on a yoke (43) with their narrow ends adjacent each other and with a gripper (46) therebetween. The arrangement being such that pieces of shrimp and straight shrimps pass through the stops and are subsequently removed from the conveyer, whereas correctly orientated curved shrimps, i.e. head trailing, are stop by the stop 44 and then released as the stop is raised and incorrectly orientated shrimps, i.e. head leading, have their heads gripped by the gripper (46) whereupon the stops and the gripper are raised, turned through 180‹ and then lowered back to the conveyer to release the now correctly orientated shrimp.

Title: Burners for gaseous or liquid fuels
IPC: F23C99/00
Filed: 1961-04-11
Abstract: 972,302. Burners. A. WOBIG. April 11, 1961 [April 14, 1960], No. 13042/61. Headings F4F and F4T. A burner comprises a spray electrode connected to a high-voltage supply and having a point or sharp edge causing an " electric wind " which carries the air and/or the fuel into the burner. The burner also has an accelerator electrode between which and the spray electrode there is a potential difference of 10, or 40 kilovolt A.C. or D.C. and which accelerates the flow of the fuel or air into the burner. The burner shown comprises three spaced curved walls 3, 4, 5 of ceramic material forming two air passages 7, 8 leading to a tubular nozzle 2 adapted to be connected to the door of a kiln. Two ring-shaped spray electrodes 10, 11 of tungsten or rhenium foil are connected together by brackets 12 and are mounted outside the inlets of the air passages 7, 8 by ceramic spacers 13. Three accelerating electrodes 14, 15, 16 formed by wire rings are embedded in the marginal beads of the curved walls 3, 4, 5. One terminal of a high-tension transformer is connected to the spray electrodes 10, 11 and the other terminal is connected to the accelerating electrodes 14, 15, 16. A metal ring 20 is seated on or embedded in the annular bead of the curved wall 4 and is connected to the central earthed tapping of the high-tension transformer. A conical metallic member 23 having a bore 24 for supplying fuel from a pressurized reservoir 25 is seated on the curved wall 5 and collects an electric charge from the ionised gas molecules, and when the charging is sufficiently high sparking to the metallic ring 20 occurs. Thus the ring 20 and the member 23 serve as ignition electrodes and the metallic member 23 also serves as a spray electrode and the ring 20 as an accelerating electrode. Charging of the ignition electrode can be supported by further collecting electrodes on grids located upstream or downstream. A capacitor and rectifiers may may be included in the ignition circuit. The air stream draws the fuel out of the bore 24 and atomizes it. In a gas burner, Fig. 3 (not shown), gas and air are driven by spray and accelerating electrodes along two passages similar to the two air passages 7, 8 of Fig. 1 and a further accelerating stage is provided at the discharge end of the gas passage by an insulated electrode and a bare metallic ring between which a highvoltage exists. The metallic ring also serves as an ignition electrode which collects charge from the ionised gas. The other ignition electrode is formed by an earthed ring on the discharge end of the air passage. An electrode may be located to hold the root of the burner flame by virtue of its potential relatively to the ions of the flame.

April 29, 1930, No. 13230. [Class 20 (iv).] A coated material for application to surfaces such as floors, roofs, or walls comprises a sheet of fibrous material such as textile fabric or felt with a coating on one side thereof consisting of a substance capable of adhering to the surface to be coated when heated asphalt or like composition is applied to the uncoated side of the material. The fibrous material may be impregnated with a mixture of pitch and tar or similar composition, and the fibrous material may be stitched or have metal clasps or staples inserted therein, and a compound sheet may be used formed of superposed sheets having the joints displaced, with or without metal reinforcement. The adhesive material may be bitumen, latex, pitch, gums, resins, or other material. In an example, a felt composed of hair and jute impregnated with a mixture of pitch and tar, is coated with a bitumen having a specific gravity of about 1À0445, a melting point of about 135‹ F., and flash and fire points of about 555 and 650‹ F., respectively. The coating may be applied by spreading by means of a roller, heated or not. To prevent adhesion in transport, a powder such as french chalk may be used. In use, the material is secured, coated side downwards, on the surface to be covered, with a reinforcement of wire netting or expanded metal if desired, and hot asphalt or similar material is applied to the fibrous material. The heat of the asphalt &c. causes the bitumen coating to adhere to the surface to be covered. When compound sheets consisting of several layers of fibrous material are used, the bitumen-coated side of one layer is disposed in contact with the uncoated side of the adjacent layer.

Abstract: 197,196. Strohmenger, A. P. May 12, 1922. Uniting by fusion. - A welding-electrode particularly for use in the Quasi-Arc process, and which may be used for welding soft iron and steel, and cast iron, comprises a metal core covered with slag-forming material, the core or its covering containing vanadium and titanium in substantially equal proportions. The weld produced by such electrodes is said to be free from nitrogen lines. An iron or steel core is first passed through a bath containing finely powdered vanadium and titanium mixed with lime and made into a slime to which sodium silicate is added. The electrode is then wound with blue asbestos yarn after which it is passed through a bath of soda and lime. The amount of vanadium and titanium used is such that the weight of each present in the finished electrode is from 0.25 to 0.5 per cent of the weight of the core. Alternatively an iron core having the following percentages of other ingredients may be used, Carbon 0.10, Silican 0.02, Phosphorous 0.02, Sulphur 0.02, Manganese 0.75, Vanadium and Titanium each 0.25 to 0.50. Such a core is parsed in succession through a bath of sodium silicate and a bath of lime after which it is wound with blue asbestos, an aluminium wire being introduced if desired, as described in Specification 13538/14, and the electrode being passed finally through a third bath of soda and lime. Specifications 1274/12 and 11079/12 are also referred to.
