Abstract: 212,215. HugÚ, E. March 2, 1923, [Convention date]. Addition to 201,166. Spray burners.-In place of the ferrule used for producing the whirling spray described in the parent Specification, helical grooves, Fig. 2, may be cut in a flat head 5 bearing against the walls of the basin 3, the thickness of the head being just sufficient to assure the direction .of the fuel flowing through the grooves. In the form shown in Fig. 3, the basin is provided with a screwed extension 6 in which is screwed the head 7 provided with helical grooves. The supply of fuel is regulated by means of a disc 8 provided with annular bearing surfaces E, F by which the entrance to the grooves may be covered. In the form shown in Fig. 4 helical grooves H are cut in an extension of the basin and are formed with inclined bottoms R'. A conical head formed with helical grooves R is formed to screw into the grooves R<1> and thus to regulate the spray. The Specification as open to inspection under Sect. 91 (3) (a) describes also a modification of the apparatus described in the parent Specification in which the basin 3 is rotated to coact with a series of different sized outlets, the supply of fuel being regulated by means of a plunger 10, Fig. 5 (Cancelled), working in a cylinder in which the tangential opening 11 is formed. As the spindle 12 is rotated to bring the basin into coincidence with the openings a screw 14 forces the plunger down more or less to close the opening 11. In a further modification the height of the plunger and the position of the basin are separately controlled, the casing being rotated by a hollow-shaft and the height of the plunger controlled by a concentric valve shaft. Fig. 8 (Cancelled) shows a form in which control is obtained by withdrawing a suitable amount of the fuel through a valve controlled outlet connected to the basin 3' through a hollow stem. This subject-matter does not appear in the Specification as accepted.

Title: Means and Methods for Synchronizing Optical Effects of Cinematographs and Acoustical Effects of Phonographs and the like.
Inventor: HOPKINS EDWIN SYLVESTER
IPC: G03B31/00
Filed: 1918-11-12
Abstract: 134,357. Hopkins, E. S. Nov. 12, 1918. Combined working of phonographs with kinematographs; cylinder records. - Picture films and associated sound re. cords for simultaneous repro. duction are produced by taking the films and records from separate enactments of a scene (or by using non-synchronous machines for a single enactment), and subsequently inserting or omitting portions of the film and record so as to produce synchronism. Fig. 1 shows a portion of a film 1 - - 12 and the corresponding sound record 13, 14 of a beil 30 rung by a clapper 31. The Figure shows the sound-waves 15 in advance of the picture 5 in which the bell is struck, and this error is corrected by removing one of the preceding pictures, say 3, and inserting an extra picture or blank between 6 and 10, so that the picture showing the next ringing of the bell may not be displaced. Alternatively, the sound record may be redistributed to bring it into synchronism with the picture film, or both methods may be adopted. The omissions and insertions of the sound record are preferably made at soundless portions of the record, and, in the case of a tape record, a.e effected by cutting and splicing. When a cylindrical record is used, the record is built up of disks 81 - - 91, Fig. 10, each of which has a helical groove of one or more turns joining up with the grooves on the adjacent disks. Selected disks may be removed or inserted to synchronize the record with a picture film. The operation necessary for synchronizing are preferably effected on the " master " sound record, and on the negative picture film, before duplicating the records and printing the positive films. It is preferred to synchronize the record and film by removing sections from the film, and, with this object, the camera during exposure is run at an accelerated speed to provide a margin of spare pictures. The spare pictures may be omitted in the operation of printing the positive film from the negative, and, if necessary, some of the negative pictures may be printed more than once on the positive film. Films may be synchronized with mechanical musical records in the same way as with phonograph records.

Title: Improvements in scanning circuits for television receivers
IPC: H03K4/43
Filed: 1939-06-28
Abstract: 639,531. Sawtooth generating circuits. MURPHY RADIO, Ltd., and HAWKINS, G. F. June 28, 1939, No. 18834. [Class 40 (vi)] In an electro-magnetic scanning circuit the internal impedance of the output valve is caused to have such a value that it can be used to damp out the unwanted high-frequency oscillations which would otherwise occur during the fly-back period of the saw-tooth. The impedance of a high impedance output valve is reduced by injecting into the grid circuit a voltage proportional to and in phase with its anode voltage by means of a small condenser connected between anode and control-grid, or by injecting a voltage derived from an auxiliary winding on the output transformer or from a potentiometer in shunt with the coils. In Fig. 2 the added condenser 13 in series with the grid coupling condenser 8 and the condersers 18 and 16 in the sawtooth generating circuit, together with the decoupling condenser 5, form a capacitive potentiometer between the anode of the output valve and H.T. negative. The grid of the output valve is tapped on to this potentiometer and the values of the capacities are, chosen to give the correct amount of negative feedback so that the output valve has the necessary internal impedance for damping during the fly-back period. The internal anode-to-grid capacity of the output valve may be of such a value that the addition of condenser 13 is unnecessary and the gain of the output stage may be adjusted by varying resistor 14. Specification 511,600 is referred to.
