Abstract: 1,090,472. Spray-producers. SIGMA ELECTRONICS Ltd. Jan. 7, 1966 [Jan 19, 1965], No. 2260/65. Heading B2F. [Also in Division G1] Apparatus for analysing the spray of fuel oil &c. produced by a nozzle 7 comprises a rotatable shutter 10 provided with a cut-out portion 12 and mounted adjacent the nozzle outlet, a tower 8 into the open upper end of which the burst of spray particles passing through the portion 12 is directed, and a dish 18 connected to a balance 19 and located adjacent the lower end of the tower so as to catch all the spray particles. The particles reach their terminal velocity before they hit the dish and the cumulative weight of the particles falling on the dish is recorded on a paper 27 using an optical system 24-26. A shutter 31 produces standard time intervals on the recording and means 29, 30 are provided for viewing the paper. A flash lamp 33 is operated in synchronism with the arrival of the portion 12 opposite the nozzle outlet. The dish 18 is then replaced by a member having a narrow slit (37), Fig. 5 (not shown), arranged at the base of the tower above a plurality of plates (36) or an intermittently rotated disc (35), and the diameters of wax particles passing through the slit and solidifying on the plates are measured. The wax is chosen so as to have the same density, viscosity and surface tension as the liquid, e.g. oil, being analysed. The cumulative weight readings are then plotted against the diameter readings. Further readings may be obtained using other nozzles or other liquids.

Abstract: 180,296. British Thomson - Houston Co., Ltd., (Assignees of Hoxie, C. A.). May 20, 1921, [Convention date]. Vibration, indicating; photographic recorders. -Relates to apparatus for recording sound and like waves photographically. In the apparatus shown in Figs. 1 and 3, sound to be recorded affects a diaphragm 17 in a transmitter 10, which diaphragm is connected to a mirror 18 by which a beam of light is reflected from a source 11 through a slit 12 on to a photo-electric cell 14. The cell is connected in the grid circuit of a thermionic valve 15 through a resistance coupling, the plate circuit of the valve including an electromagnet 16 which operates a diaphragm 19. A mirror 20 secured to this diaphragm reflects a second beam of light through a slit 40 in a casing containing a moving photographic film 39, on which an amplified record of the vibrations of the first beam of light corresponding to the sound waves is thus produced. The slits 12, 40 partially intercept the respective beams of light. Each mirror is connected to its diaphragm by rods 25, 26, Fig. 3, and is mounted on a triangular shaft 27 held in jewel bearings by a permanent magnet. The apparatus may be used for amplifying the vibrations of an oscillograph, for which purpose the oscillograph mirror is substituted for the mirror 18, and the mirror 20 and its actuating means may be replaced by a second oscillograph. The photo electric-cell is preferably of the kind described in Specification 190,218 [Class (39 (i). Electric lamps, Arc, &c.]. Fig. 5 shows a film having thereon a single record produced as described, though several such records may be made on one film. A rotating photographic plate may be used instead of a film. Specification 130,762 also is referred to. According to the Specification as open to inspection under Sect. 91 (3) (a), the amplifying- device may be dispensed with altogether, and the vibrations of the beam from the mirror 18 recorded directly. This subject-matter does not appear in the Specification as accepted.

Filed: 1975-01-21
Abstract: 1498293 Doffing wound coils SKALTEK AB 21 Jan 1975 [25 Jan 1974] 2600/75 Heading D1J A device Fig. 2 for. use in an apparatus for coiling a cable comprises. a unit 5, 6, 7, 8. that is rectilinearly movable in a first position to cause a cable 2 to be helically laid on a rotary take-up device 3, the unit 5, 6, 7, 8 being movable to a second position in a plane that is perpendicular to the axis of the device 3; and a control unit 11; the arrangement being such that when the wound coil is to be doffed the control unit 11 swings the guide unit 5, 6, 7, 8 to the second position towards a knife 9, Fig. 3, so that the cable is cut by the knife. In the drawings the unit 5, 6, 7, 8 includes a tube 8 through which the cable 2 passes. The control unit 11 is a hydraulic cylinder. When the coil is fully wound the cylinder 11 causes a hammer 10 to strike the tube 8 and cause it to swing to the setting shown in Fig. 3 where the cable 2 is cut by the knife 9. At the moment of cutting, a drum on which the coil of cable has been wound is withdrawn axially from its end flanges to permit the wound coil to fall under gravity from between the end flanges. The wound coil may drop into a container as in Fig. 3. After the cable has been cut a cylinder 12 swings the unit 5, 6, 7, 8 back to the setting shown in Fig. 2 where the cable 2 is pressed against a drive roller 13 causing forward feed of the cable. The cable 2 is then fed down the inner face of an end flange as indicated by the arrow in Fig. 2 and the drum is moved axially back through the other end flange to abut against the rope 2 and clamp it against the end flange with which it is associated. A fresh winding operation is then commenced. In a modified embodiment there are two side-by-side and parallel take-up devices 3. When the unit 5, 6, 7, 8 swings towards the knife 9 and the cable 2 is cut the unit 5, 6, 7, 8 continues its swinging motion to a setting in which it delivers the cable 2 to the second take-up device 3. In such an embodiment there is a second knife 9 facing the second take-up device 3 so that when the second take-up device 3 is full and the unit 5, 6, 7, 8 swings away from it the second knife 9 will cut the cable 2, and so on.

Filed: 1922-01-31
Abstract: 191,297. Lorkin, W. L., Daglish, E. E., and Swift, H. B. Jan. 31, 1922. Heating by electricity. - An arc-welding generator A has an inductance F wound on a closed magnetic core G arranged as a shunt to a differential series field winding C. The ordinary field winding is supplied from an independent source. During normal working, the diverter F acts as an ohmic resistance in shunt with the series coil C and is so arranged that the normal voltage is produced. When the arc is struck at D, E, the momentary short-circuit causes a heavy current to circulate, but owing to the high inductance of the diverter a larger proportion of the current passes through the differential series coil, rapidly reduces the field and so cuts down the current. The operative amount of the winding F can be varied by means of a switch J.
