Abstract: 465,085. Tunnel kilns. TECHNOTHERMIE Soc. A.R.L. June 29, 1936, No. 18006. Convention date, July 1, 1935. [Class 51 (ii)] In a muffle or electrically heated tunnel kiln, air, supplied by a fan 9 to a space 8 above the roof of the cooling zone C is led to a similar space 32 above the firing zone B and from thence passes downwardly through valve-controlled holes 33 in the roof into the interior of the firing zone to agitate the atmosphere therein and prevent overheating at the upper part. A quantity of air equivalent to that entering through holes 33 is taken off through apertures 35 at the lower part of the firing zone and, in the form shown in Figs. 1, 2, 4, supplied as secondary combustion air to conduits 36 arranged on each side of vertically directed. gas burners 10 of the kind described in Specification 449,116. Each combustion chamber has an apertured roof 17 through which the gases pass into a roof space 19 and thence down flues 16 alternating with the combustion chambers, the flues 16 communicating at their lower ends with a collecting flue 20 which has branches 22, 23 serving to deliver the gases to passages 24, 25 along the sides of the preheating zone A. The combustion chamber roofs 17 are constructed of hollow bricks 37 which are cooled by air supplied through ducts 40 from spaces 2, 3 disposed along the sides of the cooling zone and receiving air from the fan 9. The air escapes from the hollow bricks 37 through apertures 39 and passes into the roof space 19 to mix with the combustion gases therein. The greater part of the air heated in the spaces 2, 3 is led by downwardly tapering passages 4, 5 to underground flues 6, 7 which supply primary air to the burners 10 and deliver, at 28, 29, any excess air into the combustion gases entering the passages 24, 25 of the preheating zone. Fig. 9 shows a modification in which heavy oil burners 43 deliver horizontally into flared passages 44 at the lower ends of the combustion chambers, the primary air being supplied from the flues 6, 7 through ducts 11 each of which has two branches 11a, 11b serving adjacent burners.

Title: Improvements in or relating to lasers
IPC: H01S3/101
Filed: 1965-04-30
Abstract: 1,087,822. Lasers. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 30, 1965 [May 1, 1964], No. 18244/65. Heading H1C. [Also in Division G2] A laser emitting polarized light from an active medium 1, Fig. 1, has the stimulated emission restricted to a selected region of the active medium, the region of emission being determined by the potential applied to an electrooptic crystal 20 which operates in association with a Babinet compensator 8 in the laser optical cavity. The active medium may be either a gas the emitted light from which passes through windows 2 at the Brewster angle or a ruby. The optical cavity is defined by mirrors 4, 5 one of which passes an output beam 6. The electrooptic crystal 20 may be a potassium dihydrogen phosphate crystal having transparent electrodes 21 to which an adjustable and reversible control potential is applied from a source 24. In the absence of control potential the stimulated emission is restricted to a narrow region extending across the active medium and coplanar with its axis, the Babinet compensator causing circular or elliptical polarization of light emitted from all other regions. Only reflected plane polarized light is of sufficient intensity to effect lasing in the region where it passes through the active medium. The function of the electro-optic crystal is to effect a phase shift in the light passing through it which is opposite in effect to the phase shift produced at a corresponding point in the Babinet compensator, the amount of phase shift being determined by the magnitude and polarity of the control potential. When such a potential is applied, complete phase cancelling of the phase shift produced in light passing through the compensator is obtained in a planar region offset from the laser axis. By appropriate control the narrow lasing region in the active medium can thus be selected as required. In an alternative arrangement, Fig. 4 (not shown), and Fig. 6, a further Babinet compensator 31 and electrooptic crystal 32, together with a polarizer 30 are positioned in the optical cavity with a 90-degree optical relationship to the original components 8, 9. Consequently by suitable potential values from sources 24, 38, only a filament of the whole active medium 1 is able to lase. A modification, Fig. 6, uses a spherical mirror 40 in place of mirror 4, the mirror 40 and a lens 41 having a common focal point P within the active medium. Consequently the selected lasing region is in the form of a narrow double cone within the active medium. This arrangement includes a mask 44 with character-shaped portions through which the output beam may pass, the beam being then directed by a lens 45 on to the surface of a movable light-sensitive material 46. By suitably adjusting the potentials applied to the electro-optic crystals 9, 32, a selected cone-shaped portion of the active medium lases and a corresponding character in the mask is recorded on the film.
