Title: Automatic radiation pyrometer
IPC: G01J5/60
Filed: 1975-05-07
Abstract: 1507367 Radiation pyrometers SIEMENS AG 7 May 1975 [10 June 1974] 19234/75 Heading G1A A radiation pyrometer for measuring the temperature of a primary source measures the amount of radiation received from that source in each of two different wavelength ranges, and stores the ratio of these amounts; the pyrometer has a secondary source whose temperature is adjusted until the ratio of the amount of radiation it emits in the same two ranges equals the stored ratio, at which point the temperature of the secondary source, which then equals that of the primary source, is measured. In Fig. 1, the radiation from primary source 1 to be investigated is received by two photodetectors 3,3' responsive to differing parts of the spectrum, and the ratio of the detector signals is found at 4. With switch 5 as shown the ratio is fed to store 6, the stored value being supplied to a comparator 7. Once the ratio has been stored, control unit 10 activates a power supply 9 for the secondary source 8 and also changes over switch 5. Whe comparator 7 signals that the ratio equals the stored value, unit 10 triggers a measurement of the secondary source temperature, this being effected at 12 by measuring the heating current or the resistance. The temperature is read out on digital display 11. The secondary source 8 should be made of a material producing the same spectral radiation distribution as that of the primary source to be measured. The photo-detectors may be semiconductors, e.g. germanium.

Title: An improved process for the treatment of zinc oxide
IPC: C09C1/04
Filed: 1934-06-29
Abstract: <PICT:0425664/III/1> The flow of the oxide fumes leaving the combustion chambers of zinc oxide furnaces is retarded before they pass to the precipitating chambers, whereby the heat content of the fumes, whose cooling is thus retarded, effects a thermal treatment of the zinc oxide for improving its quality.  As shown in the Figure, zinc volatilized in retorts 1 and burnt in the chamber B together with gas introduced from pipes 2 and 4 by means of air supplied at 5 passes to a chamber C the outlet of which is throttled by damper 11 before being collected in the precipitating chambers D. The chamber C is wholly or partially heat-insulated to maintain the fumes at a temperature of 500--800 DEG  C.  In an example where the burning zinc vapour has a temperature of 1200 DEG  C., the temperature within the chamber C is kept at 700 DEG  C.

A machine for drawing rods or tubes includes a drawing carriage 5 which is moved by driven rollers 4a-(4h) guided on guide tracks 3, 3a. The rollers 4a-(4h) are pressed downwardly and upwardly against the guide tracks 3, 3a and are arranged in pairs in bridges 7-10, 7a-10a. Each pair of rollers is urged against the guide tracks 3, 3a by pistons (11) (Fig. 5, not shown) in cylinders 12 pressing against each bridge 7-10, 7a-10a. The pressing force of the rollers against the tracks 3, 3a may be increased by oil pressure behind the pistons (11) in the cylinders 12. A group of four rollers is driven by one of four oil motors 15-18 through geared connections between each motor and the shafts of the rollers. The oil is supplied to the motors through pipe lines (20) (Fig. 2, not shown) hinged to sliding members (21) movable along the guide track 3 and through a distributer 25. An hydraulic circuit is described for automatically first moving the carriage 5 slowly in the drawing direction after which it is moved at the desired drawing speed. After the carriage has been stopped by operation of valves interrupting the supply of oil to the motors 15-18, it is rapidly returned using the oil motor 15 only to drive four rollers only. The braking operation is initiated a short distance from the die support.

Title: Improvements in automatic guns of the gas tap type
IPC: F41A5/28
Filed: 1956-06-26
Abstract: 793.289. Automatic guns. BREVETS AERO-MECANIQUES SOC. ANON. June 26, 1956 [July 26, 1955], No. 19786/56. Class 92 In automatic guns of the kind in which the propellant gases operate a piston or the like the passage of the gases from the gun bore to the piston chamber is regulated by a heat sensitive device to prevent an undesirable speeding up of the rate of fire as the temperature of operation rises. As shown in Fig. 2, the bore of the gun communicates with a cylinder 3 and piston head 4 through a channel 7 in the metal chamber-block 9. A plug 8, screwed into the block 9, restricts the passage of the gases to an annular area 6 which decreases if the plug 8 expands relatively to the block 9 due to a rise in the temperature of operation of the gun. To correct a tendency to over-compensation one or more small channels 11 may be drilled in the head 5 through which a portion of the gases will flow directly from the conduit 7 into the cylinder 3. The plug 8 is drilled externally with a blind hole 10 which is open to the atmosphere and which assists in cooling: it. A further embodiment is shown in Fig. 3 in which the restricted area 18 is between conical surfaces and the compensating channels 19 are cut either in the plug 17 or on the conical face 13 of the block 9.
