Title: Electronic frequency modulator
IPC: H03C3/10
Filed: 1948-10-15
Abstract: 667,065. Frequency modulation. STANDARD TELEPHONES & CABLES, Ltd. Oct. 15, 1948 [Dec. 3, 1947], No. 26832/48. Class 40 (v): A generator is modulated in average frequency by an auxiliary impedance intermittently made effective in the generator frequency determining circuit for a proportion of each cycle of the generated wave determined by the modulating voltage. In Fig. 1 a condenser 42 is made effective across the tuned circuit 40 of an oscillator for a variable proportion of the positive half cycles of the carrier oscillations at their peaks, when a diode 44 in series with the condenser 42 and a resistance 22 is rendered conducting, the proportion being determined by the amplitude of a D.C. modulating potential across the resistance 22. An oppositely poled diode 45 between the condenser 42 and earth recharges the condenser 42, as and if necessary, during negative half cycles, to the normal condition in the absence of diode 44 of applying a positive back potential, equal to the A.C. voltage peak of the oscillation, on the anode of diode 44 and cathode of diode 45. The voltage applied to the anode of diode 44 therefor varies between O and twice the peak voltage of the oscillation. The oscillator includes a limiter 34 the load resistance 49 of which coacts with the impedance of the tuned circuit to produce an oscillation of amplitude independent of valve characteristics. In Fig. 3 (not shown), the voltage across resistance 22 is constant and the modulation is applied to the load resistance 49 of the oscillator to vary the amplitude of the tuned circuit oscillations. In Fig. 4, using contact rectifiers in place of diodes, the modulation is added to a constant voltage across the resistance 22 and an amplitude limiting rectifier 52 is connected between the tuned circuit and resistance 22. The resistance 22 determines the mean frequency of the oscillations and any variation of it produces a corresponding variation of the amplitude of the tank oscillations, thereby counteracting change of mean frequency. In Fig. 6 (not shown), the modulation acts through diodes to vary the portions of oscillations during which resistances 62, 70 in the phase shift networks of a resistance-capacity oscillator are short circuited.

Title: Improvements in or relating to insecticidal sprays
IPC: A01N25/30
Filed: 1939-10-04
Abstract: 535,657. Insecticidal emulsions. ORELUP, J. W. Oct. 4, 1939, No. 27209. [Class 81 (i)] [Also in Group III] An emulsion for insecticidal sprays consists of mineral oil and water emulsified with a condensation product of coconut fatty acids and tri- or tetraethylene glycol. The emulsifying agent does not affect the vegetable oils and so prevents damage to plants on which the emulsion is sprayed. It is preferred to mix “ to 5 per cent of the condensation product in the oil and ¥ to 4 per cent of the mixture in water. The emulsifying agent may be prepared by condensing the fatty acids with the glycols in known manner or by-passing ethylene oxide into the fatty acid mixture to the required extent.

Abstract: 1307327 Endless-chain conveyers KORNYLAK CORP 19 April 1971 [24 April 1970 27318/71 Heading B8A  Load carrying platforms 16 carried by endless chains 12, 14, are normally maintained in a horizontal altitude but are tilted in one direction on one side of a transfer station and are then tilted in the other direction when they pass to the other side of the transfer station. Thus a load on a platform 16 passing downwardly through a transfer station A (Fig. 5) and initially horizontal at a position U, will slide off the platform on to a conveyer belt 64 when the platform reaches position P. It returns to the horizontal for loading at position H, and is tilted again at position L so as to enable the load to be moved into a stable position against stop members 21 of the platform. Control of the altitude of the platforms is realized by the action of three sets of trackways on each side of the conveyer. One set is defined by flanges 56, 56, (Fig. 2), which guide rollers 58 carried by the pivots on each side of the platform. The other two trackways 32 and 34 guide respective rollers 28, 30 at the ends of the two arms 24, 26 of a bellcrank rigid with each side of the platform 16. The platforms are tilted into a vertical position X (Fig. 2) on the return run of the conveyer.

Title: Improvements in or relating to burners for furnaces
IPC: F23D17/00
Filed: 1926-11-04
Abstract: 261,006. Hetsch, F. K. Nov. 4, 1925, [Convention date]. Spray, pulverulent fuel, and blowpipe burners.-The casing 1 of a burner is formed with an inlet 2 for air or steam, an inlet 3 for combustible gas or air charged with combustible material such as coal-dust or sawdust, and three inlets 5 for liquid fuel communicating with an annular supply groove 19 in a ring 4. The casing is open at both ends one end forming the discharge nozzle and the other being closed by a coverplate 6. The coverplate 6 is formed with a tubular extension 7 which communicates by an opening 44 with the gas inlet 3 and carries an extension member 8. A spindle 9 passing through the coverplate 6 carries the hub 14 of a piston valve slidable in the ring 4. The spindle 9 may be turned so as to move the piston valve axially by means of a hand-lever 11 having a projecting lug 12 which is maintained in engagement with a notched cam-shaped guide 18 on the cover 6 by the pressure of a spring 42 on the hub 14. The movement of the piston valve regulates (1) the air issuing into the burner nozzle between surfaces 15, 16 on the casing and valve, through a port 20 formed in the valve, and between surfaces 17, 18 on the valve and extension 8, (2) the gas entering the discharge nozzle between a surface 23 on the extension 8 and a surface 24 on the hub 14, (3) the number of radial oil holes 25 in the valve in communication with the annular groove 19. A rotary movement is imparted to the gas and air by helical ribs 21 connecting the piston valve to the hub 14 and by helical ribs 22 arranged in the air passage between the surfaces 17, 18. The ribs 22 may increase in thickness in the direction of flow. The guide 13 and surfaces 15, 18, 23 are so shaped as to permit a fine adjustment of the burner for light fuel consumptions and a coarser adjustment for heavy fuel consumptions. To prevent dribbling, the piston valve is formed with grooves 26 - - 29 communicating with the interior by radial holes 30. A chamber having a siphon tube overflow may be provided in the casing to lead off oil oozing past the valve. When a low grade gas is being burnt the air and gas inlets may be interchanged and when liquid fuel only is being used air may be admitted through the opening 44. The spindle of the piston valve may be hollow to-allow the introduction of a gas flame or electric igniter at starting and to form a sight hole. The surfaces 15, 16, 18, 23 are approximately cylindrical form and are carried by detachable parts so as to be interchangeable with others according to the different pressures &c. of gas 'and air employed. In a simpler construction of burner the middle air port is omitted.

Abstract: 205,337. Parker, Winder, & Achurch, Ltd., and Wood, J. A. Oct. 1.4, 1922. Double and multiple hinges for mounting or casement window so as to provide access to either side for cleaning purposes comprise a lug 13 on the plate 5 connecting the attachment flaps 1, 2 secured respectively to the frame and window, the lug member projecting into a recess 17 in the window and being engaged by a locking member projecting through the adjacent edge of the window. In Fig. 2, the locking member is a pin 21 on a plate 20 rotatable by a turn-button 19 mounted in a plate 18 closing the end of the slot 17. The plate 1 has a recess to accommodate the member 19 when the window is in the closed position. For cleaning the outer surface of the window, it is partly opened by movement about the hinge pin 6 and then the turnbutton is operated to free the lug 13 and allow the window to be opened about the hinge pin 7. The plate 2 is housed under an offset portion 8 of the plate 5 and the hinge pin 6 is spaced away from the corner of the window frame by cranking the member 5. In the arrangement shown in Fig. 5, the lug 13 is slotted for engagement with a key-like locking member 25 inserted through a slot 27 in the covering plate 18. In a further modification, the lug is engaged by a slidable locking member, which is movable up or down to free the window or lock it to the connecting plate.
