Abstract: 909,121. Controlling burners. SULZER FRERES S.A. Dec. 21, 1960 [Dec. 23, 1959], No. 43941/60. Addition to 883,251. Class 75 (1). [Also in Groups XII and XXXV] In a furnace having a burner for each of a number of different fuels at a number of combustion points the total output of the furnace being regulated by proportional adjustment of all the burners, according to the parent Specification [Group XII], the number of burners in use for a fuel which cannot be readily stored is automatically controlled to keep the amount of that fuel in the supply line between upper and lower limits. A comer fired furnace has four burner rows, each of four combustion points with heating capacities in the ratio 1:5:25:25. The burners of each row have a common air supply 5, end common oil and gas supply lines 6, 7. The gas jet 8 and oil jet 9 at each burner position are controlled by valves 10, 11 linked to a spring-loaded T-shaped lever 12 actuated to change over from oil to gas by a solenoid 15. An automatic control 50 for the total gas supplied to the burners is arranged downstream of a pressure switch 32 controlling a reversible motor driving a selector drum 20 in one direction if the pressure in the gas supply line 30 rises above an upper limit, and to reverse the drum if the gas pressure falls below its lower limit. The selector drum 20 is arranged to open the gas supply to the appropriate number of burners by energizing the solenoids 15, the gas valves of the other burners remaining closed. In a furnace burning pulverized coal, oil and a gas which cannot be readily stored, Fig. 3, not shown, the changeover arm at each burner position is connected to the gas valve and to a second T-shaped lever arm adapted to actuate the oil and pulverized coal valves so that both are closed if the gas valve is open, and if the gas valve is closed, a manually selected one of the oil and coal valves is open. When the coal valve is closed, the coal is returned to a cyclone, separated from its carrier air and stored.

Filed: 1959-12-28
Abstract: 939,957. Automatic control of telecameras. BODENSEEWERK PERKIN-ELMER & CO. G.m.b.H. Dec. 28, 1959 [March 19, 1959], No. 44033/59. Class 38 (4). In a system for automatically maintaining a telecamera trained on a target, the electron image of a converter tube moved in unison with the telecamera is scanned and signals thus produced, representing movement of the target from the centre of the field of view of the telecamera, are used to control servomotor means adjusting the telecamera in elevation and bearing to bring the target image back to the centre. In Fig. 1 a television camera 6 is attached to a camera theodolite 1 and electric signals derived from the television camera image and representing movements of a target, control servomotors, such as elevation servomotor 13, which maintain the television camera, and thus the theodolite camera, trained on the target automatically. Initial setting of the cameras is facilitated by a manual controller 5 which may be substituted for automatic control by operating a switch 11. The theodolite image and the television image reproduced on a screen 9 are superimposed for viewing through an eyepiece 10 for manual control purposes. To reduce cost, the two cameras may share a common optical system having a light ray dividing device. A control unit 3 synchronizes the theodolite camera shutter &c. with the shutters of other cameras (not shown) trained on the same target, and the spatial co-ordinates of the target may be computed from signals obtained from the several theodolite systems.

Abstract: 1,148,536. Lampholders. CARR FASTENER CO. Ltd. 4 Aug., 1967 [4 Oct., 1966], No. 44281/66. Heading H2E. A lampholder, for assembly in an apertured panel with electrical conductors on one surface thereof, comprises an insulating body 1 mounted in a sleeve 3 so that the body is capable of axial but not rotational movement with respect to the sleeve. The body 1 has a lamp-base receiving cavity 2 in which a pair of contacts is mounted, each contact comprising a relatively rigid arm 6 having a lateral extension 7 which engages a conductor on the apertured panel, a resilient arm 8, which engages a contact on the base of the lamp, and a tailpiece 9 having a resilient tongue 10 which engages a recess moulded in the body 1. A spring 13 encircles the body between the body and the sleeve, opposite ends of the spring abutting inwardly extending lugs 4 on the sleeve which engage in longitudinal grooves 5 on the outer peripheral surface of the body 1, and shoulders 12 on the body. The body is formed with a flexible skirt 14 extending axially outwards of the lamp base receiving end of the cavity. To mount the lampholder in an aperture, the body 1 is displaced axially relative to the sleeve 3 against spring 13 and is moved into the aperture until the contact extensions 7 have passed through notches adjacent to the edge of the aperture; the holder is then rotated until tabs (not shown) on the forward end of the sleeve register with complementary holes in the panel, after which the displacing force is removed so that the panel is gripped between extension 7 and sleeve 3.

Title: Production of electrical discharges in gaseous working media in cavities
IPC: H01S3/0971
Filed: 1970-09-16
Abstract: 1306746 Lasers AVCO CORP 16 Sept 1970 [19 Sept 1969 29 June 1970] 44331/70 Heading H1C A gas discharge is stabilized by flowing the gas at a rate which maintains the temperature of the gas below a level at which non-uniformities such as arcs occur. Fig. 1 shows the discharge tube of a gas laser having three sets of electrodes 21, 22, 23. Gas flows across these electrodes from inlet 11 to outlet 13, and a resonant cavity is defined by mirrors 28, 29. Two discharges are used, the first one being between electrodes 22 and 23 to create a spatially uniform distribution of electrons, while the second discharge between electrodes 21 and 23 accelerates the electrons but maintains the spatial uniformity. The first discharge occurs in response to short, high voltage pulses from supply 36-38, while the second, sustainer discharge is in response to longer pulses of lower voltage from supply 35, 36. The electrode ends are recessed to avoid arc formation, and the bodies of the electrodes may be shaped to aid the gas flow. The flow rate of the gas is balanced against the electrical input power to avoid undue heating, the outlet gas temperature being 600-700 K. for a CO 2  laser. The gas may be cooled prior to entering inlet 11. The sustainer electrodes are fed from individual capacitors by a thyratron control (not shown). Typical operating parameters are given in Table 1 (not shown). The laser action in Fig. 1 uses a region of gas between electrodes 21 and 23, but the region downstream of electrodes 23 may also be used. The laser may be used as an amplifier. Gases referred to are CO 2 , CO, N 2 , N 2 O, NO, NO 2 , HBr, HCl, HF, He, H 2 , Ar and SO 2 . The flow controlled double discharge may be used to stabilize gas discharge devices which cannot be stabilized by conventional diffusion of electron-ion pairs to the device walls. Thus the invention may be used with discharges of high pressure in large dimension devices, including MHD and chemical reaction devices.
