Title: Industrial oven or foundry ladle heating furnace - where sliding shutter prevents slag falling from inverted ladle into burner outlet hole
IPC: F27D99/00
Filed: 1977-03-19
Abstract: Sliding shutter used to cover the flame outlet hole of a burner, esp. a vertical hole above a burner used on a foundry ladle heater. The shutter travels horizontally over the top edge of the outler hole to open or close the hole. A wt. id pref. attached to one end of the shutter so the latter closes the burner outlet hole via gravity acting on the wt. whereas a hydraulic cylinder uses the fuel oil as an indirect means of exerting pressure to open the shutter; the overall result is that the shutter closes automatically due to the wt. when the fuel oil is switched off. Used for heating ladles prior to filling them with molten metal. System provides a simple, automatic method of keeping the burner outlet hole closed so that slag and dross cannot fall through the hole, e.g. when a ladle is placed upside down on a table above the burner.

Title: Hot dip zinc coating of steel strip - with prior removal of surface oxide by plasma burners producing redn. gas
Inventor: PAULUS PHILIPPE
IPC: C23C2/02
Filed: 1977-03-31
Abstract: Process for the continuous prodn. of galvanised steel sheet, where, after subjecting the steel to a suitable heat treatment, it is reheated up to its immersion temp. for the bath of zinc with the simultaneous redn. of the surface oxide on the sheet. The novelty is that the oxide is reduced by means of plasma burners producing a reducing gas. The steel sheet pref. travels through a chamber contg. plasma burners fed by gases such as CH4,NH3,H2 or, alternatively, by a mixt. of hydrocarbon gas (e.g. natural gas) and oxidising gas (e.g. O2), where partial combustion produces CO+H2. One surface of the sheet is pref. exposed to the plsma burners while the other side is cooled by a non-reducing gas or a cooled roll. Process provides a simple method of removing surface oxide so a good, adherent Zn coating is obtd.

Title: Light emitter with laser diode control - uses detector output signal and has circuit providing output and bias control signals for diode
Inventor: EPWORTH RICHARD EDWARD
IPC: H04B10/50
Filed: 1977-07-02
Abstract: From the output of a detector comprising a photodiode (1) and a wide-band amplifier (2) are derived a first signal (P1), corresponding to the level of maximum modulation, and a second signal (P0), corresponding to the minimum level of modulation. The second signal (P0) is subtracted from the first signal (P1) in a differential amplifier (9). The output (PM) represents the value of modulation. This output (PM) is fed to one input of a comparator (10), and a modulation reference signal (PMref) is fed to another input. The output of the comparator (10) is used to keep the laser to its predetermined output. The second signal (P0) is also compared in a second comparator (11), with a reference threshold value (P0 ref) representing the required emission threshold. The output of the second comparator (11) is a threshold error signal which is used to adjust the bias voltage of the laser diode.

Title: Telemetry system with parallel or serial operation - changes to serial mode on command for special reports
Inventor: GUZMAN-EDERY JORGE DIPL ING
IPC: H04Q9/00
Filed: 1979-03-22
Abstract: A number of outstations (US1 ....) send routine data simultaneously over their own individual channels to a recorder (E) in a central (1). There is also a single control channel from the central, connected to the outstations in series. Each outstation has a logic (L) controlled switch (K1 ....) which can disconnect the control channel from all later stations in the series. The central can interrupt the routine data transmission to call for spontaneous reports by sending an interrogation signal over the control channel. Any outstations with such data to report (US2, US4, Us5) respond by opening their switches (K2, K4, K5). The first (US2) then sends its data and afterwards closes its switch (K2). The next (US4) follows suit and so on. The central then removes the interrogation from the control channel and normal simultaneous transmission is resumed.
