IPC: F23D11/10
Filed: 1928-05-21
Abstract: 315,056. Todd Oil Burners, Ltd., and Clark, E. May 21, 1928. Spray burners.-A liquid-fuel burner contains a whirl chamber into which the fuel may be introduced tangentially under high pressure or axially under low pressure for atomization by air or steam introduced tangentially, the depth of the whirl chamber, the apertures from the tangential passages into the whirl chamber and the aperture through which the spraying agent passes into the whirl chamber being simultaneously .adjustable. The burner shown comprises a body part a formed with two inlets c, c<1> and provided with an extension b to which an apertured cap l is secured by a nut m. A needle valve n is formed integrally with a spindle f which is threaded to engage a nut f<2> mounted adjustably on studs p projecting from the body a. The spindle f is formed with a projection n<1> engaging a slot in a nozzle k which screws in a plug h. The plug h screws in the extension b and is formed with flats h<2> .so as to form channels h<1> communicating with tangential channels on the end of the plug. The pitch of the thread on the spindle f may be double that on the nozzle k so that by turning the hand wheel z the depth of the whirl chamber formed between the nozzle k and the plate l, the discharge apertures from the channels j, and the position of the needle valve n relatively to its seating o in the nozzle k are simultaneously adjusted. In use, liquid fuel may be supplied at low pressure to the body part through the inlet c and pass through the aperture o into the whirl chamber for atomization by steam or air supplied through the inlet c<1> and entering the whirl chamber through the tangential channels j or, alternatively, liquid fuel may be supplied at high pressure through the inlet c<1> to pass into the whirl chamber through the, tangential channels j. When supplying the liquid fuel at high pressure the valve n may be moved to close the aperture o by adjusting the nut f<2> on the studs p. The burner may be mounted in a framework u secured to the galley stove, furnace, &c., by providing the inets c, c<1> with coned surfaces to engage the coned ends of extensions s, s<1> of the supply conduits, the extension s<1> being carried by an adjustable screwed sleeve t.

Title: Heart pacemakers
IPC: A61N1/368
Filed: 1970-03-26
Abstract: 1307912 Heart pacemakers AMERICAN OPTICAL CORP 26 March 1970 [26 March 1969] 14926/70 Heading A5R [Also in Division H3] A heart pacemaker comprises an electrode E3 for connection to a patient's heart for atrial stimulation, an electrode El for connection to the heart for ventricular stimulation, means for detecting the beating of the heart, means for generating an electrical stimulus on electrode E3 following a first predetermined time interval after the detection of the last beating of the heart, and means for generating an electrical stimulus on electrode El following a second predetermined time interval after the detection of the last beating of the heart. A capacitor 57, Fig. 1, charges via variable resistors 35 and 37 until, after the second time interval of about 800 m. sec., it reaches a voltage at which transistors T7 and T8 conduct, discharging capacitor 57 therethrough and causing a transistor T9 to conduct to produce a ventricular stimulating impulse between electrodes El and E2 due to discharge of a capacitor 65. Similarly, after the first time interval of about 600 m. sec., an atrial stimulating impulse is produced between electrodes E2 and E3 due to discharge of a capacitor 65', Fig. 3. A ventricular contraction produces a signal on electrode El, corresponding to the E.C.G. R wave, which is applied to transistor Tl which then causes transistors T6 and T6' to conduct to discharge capacitors 57 and 57' respectively, thus preventing application of pulses to electrodes El and E3 if the R wave occurs before the end of the first time interval, atrial stimulation occurring and ventricular stimulation being prevented if the R wave occurs after the end of the first time interval but before the end of the second time interval. The heartbeat detection circuit is prevented from operating during atrial stimulation by a normallyconducting FET transistor 92, since when an atrial stimulating pulse is applied to electrode E3 this pulse also charges a capacitor 93 via a diode 95 causing transistor 92 to turn-off for a period corresponding to the duration of the atrial pulse plus a short period dependent on the time-constant of the capacitor 93 and resistor 94 circuit. Part of the circuit comprising transistors T3, T4 and T5 prevents conduction of transistors T6 and T6' in the presence of noise signals in a manner disclosed in Specification 1266907.

Filed: 1972-03-30
Abstract: 1362904 Gas-blast circuit-breakers BBC BROWN BOVERI & CO Ltd 30 March 1972 [2 April 1971] 15037/72 Heading H1N A gas-blast circuit-breaker has a contact member 8 moved alternately in opposite directions for its opening and closing operations by a gas-operated drive 9 which prepares for the next operation during each successive operation, a blast valve 12 to supply gas under pressure to the contacts 7, 8 and the drive 9 when open, an insulating rod 17 which permits the blast valve to open under gas pressure when released by a releasing device 23 . . . 25, and a system of levers 13 . . . 16, 10, 19 interconnecting the valve 12, rod 17 and drive 9 so that during each operation the drive 9 recloses the valve 12 and resets the releasing device 23 . . . 25. In the arrangement shown, the energization of a winding 25 causes the weakening of the field of a permanent magnet 24 to release an armature 23. The rod 17 with a crosshead 16 attached to it can now move up, so that the gas pressure acting on the blast valve 12 can open the valve 12. The contact 8 is now opened by pressure gas acting on the drive 9 which incorporates a slide valve which is moved into a position such as to reverse the flow of gas to the drive member for a subsequent reclosing operation. The contact 8 through linkage 10 turns a hollow shaft 11, which through a crank and a link 19 moves the central pivot of a two. armed lever 14 to close the blast valve 12 and to move the cross-head 16 down so that the armature 23 is again held by the magnet 23. The shaft 11 is connected at its lower end by linkage 26 to a rod 27 for indication and signalling the switch position. Rotation of the shaft is prevented by a locking pin 21 which is released by the cross-head 16 when the rod 17 is released by the device 23 . . . 25.
