Abstract: 661,007. Cement kilns. KING, F. Sept. 1, 1948, No. 23067/48. Class 51 (ii). A vertical furnace for burning cement &c. of the type having at its top a feed opening followed successively by preheater, sintering and cooling zones, is characterised by the fact that the sintering zone comprises a slit-shaped fire chamber, the width of which diminishes gradually as the chamber extends upward and having at its base a number of oppositely arranged gas nozzles discharging into said fire chamber. As shown, the furnace comprises a slit-shaped chamber 2 formed by walls 1 of insulating bricks divided into a preheating zone 3, sintering zone 4 and a cooling zone 5, the width of zones 4, 5 being greater than that of zone 3. Combustion air, travelling in counter-current to the downward movement of cement &c., is drawn through the discharge openings 15 at the bottom of the kiln by a suction fan 24 mounted on the furnace hood 23, combustion of gaseous fuel issuing from the burners 6 taking place in the zone 4. The hot combustion products in flowing towards the flue preheat the material to be burnt in the zone 3. Regulating flaps 25, mounted in the hood 23, control the draught produced by the fan 24. Cement &c. is fed into the chamber 2 from a rotatable drum 14 through a hopper 13 by a conveyer 11 rotating in a helically slit trough 10 and after passing down the furnace is discharged through the openings 15 controlled by the liftable gates 16. The burnt material is collected from the platforms 17 by stripping trucks 19 from whence it is dropped on to the conveyer bands 22. The length of the slitshaped chamber 2 is a multiple (over 2 times) of its width which is. preferably below 2000 mm. Instead of gaseous, liquid fuel may be used.

Title: Method of Magnetic Recording and Reproducing of High-Frequency Signals.
IPC: H04N5/92
Filed: 1968-05-15
Abstract: 1,191,593. Video recording. LOEWA OPTA G.m.b.H. 15 May, 1968 [20 May, 1967], No. 23091/68. Addition to 1,135,515. Heading G5R. In an arrangement for recording and reproducing colour television signals on or from a magnetic tape, the luminance signal frequency modulates a first carrier and the colour difference signals, alternately at line frequency, modulate a second carrier having a frequency such that the highest frequency in its modulated frequency band is below that of the lowest frequency in the modulated frequency band of the first carrier and the modulated signals are combined and applied to a single head recording oblique tracks on the tape. The Y (luminance) signal is applied at input 1 and frequency modulates a carrier F2 in modulator 2. The resultant signal is amplified 3 and applied to recording head 4. The R-Y and B-Y (difference) signals are applied via an electronic switch 9 operating at line frequency to frequency modulate a carrier F1 in modulator 11 and the resultant signal is amplified and also applied to the head 4. On play back the signal is reproduced in head 5, amplified 15 and separated by the HP and LP filters 16, 21. The signals are then demodulated 17, 22 amplified 18, 23 and the Y signal is applied directly to the output terminal 19. The output of the difference signal amplifier 13 is applied to a switch 28 operating at line frequency either directly via line 29 or via a delay element 24, introducing a delay equal to a line period, and an amplifier 25. The arrangement acts such that if e.g. terminal 34 receives the current B-Y signal, terminal 33 is energized by the R-Y signal of the previous line and vice versa.

Filed: 1925-09-24
Abstract: 262,879. Siemens - Schuckertwerke Ges., and Berthold, R. G. Sept. 24, 1925. Low - pressure metallic-vapour apparatus; vacuum tubes.- The supply of electrons forming the main discharge is provided by an auxiliary arc or glow discharge, which takes place within a jacket having openings leading to the control chamber, and a high vacuum is main. tained in the control chamber bv the suction action of the auxiliary discharge. As shown in Fig. 1, an auxiliary arc discharge between a mercurv cathode 3 and an anode 4 is confined by a perforated sheath 5, having bent-cut portions arranged so that gas is withdrawn from the space containing the anode 2 to which electrons pass from the arc discharge. The sheath may be used as a control electrode, or separate grids may be provided. The vessel enclosing the anode 4 is cooled externally, and gas may be evacuated from the anode space. As shown in Fig. 3, the auxiliary arc discharge between a mercury cathode 3 and a mercury anode 4 passes through one or more nozzles 6 so that gas is withdrawn from the space containing an anode 2 and a grid 13. The streaming speed of the gas in the arc should be equal to or higher than the molecular speed due to the temperature of the gas in the arc. As shown in Fig. 5, the auxiliary arc passes outside a hollow cylinder 60 and the condensed mercury overflows from the anode 4 to the cathode 3 through the inside of the cylinder, baffles 110 being provided to prevent the passage of the arc inside the cylinder. In the arrangement shown in Fig. 6 the sheath 5 is provided with one or more sets of sloping slots 7 formed by curved guides, and a magnetic field is produced by a winding 16. The sheath is of magnetic material coated with enamel, and the guides are of nonmagnetic material such as porcelain or steatite; or the sheath may consist of powdered iron mixed with glass or powdered quartz. The arrangement is such that electrons are deflected Ly the magnetic field and have a free path through the slots, and gaseous ions strike the guides and condensed mercury flows back to the inside of the sheath. The walls of the sheath may be made hollow for the passage of a cooling medium. A grid 20, consisting of strips mounted edgewise to the path of the electrons, shields electrons passing through the slots from the varying electrostatic fields of the central grid 19 and anode 2. For the same purpose the winding 16 may be energized from the anode 2 or grid 19. A magnetic yoke may be mounted close to the upper or lower end of the sheath or inside the sheath ; or the anode may form the yoke.
