Title: Regenerative heat exchangers
IPC: F28D17/04
Filed: 1960-09-02
Abstract: 923,627. Thermal regenerators. AIR PREHEATER CORPORATION. Sept. 2, 1960 [Sept. 8, 1959], No. 30312/60. Class 64 (1). In a thermal regenerator of the rotary duct, stationary matrix type, the rotary ducts 44A, 44B are rotated by a telescopically-adjustable shaft having tensioning means extending therethrough and adjustment means at opposite ends of the shaft to axially vary the clearance space between the ducts and the adjacent end faces of the matrix (not shown), contained in the annular chamber formed by concentric drum members 20, 22. In the form shown, the shaft is in three sections 50A, 50B and 50C, movable axially with respect to each other, the shaft sections 50A and 50B passing through supporting bearings 64 and the shaft section 50B being positively driven through a gear 68. Flexible tensioning members 74 extend through the shaft and are connected at one end to an end-plate 76 and at the other end to a plate 78 adjustable axially by means of a nut 88. In the operation of the regenerator the higher pressure fluid flows through the rotary duct members 44a, 44b and tends to force and maintain them apart hence providing the necessary clearance between these members and the matrix end faces. This clearance may be varied by adjustment of the tension in flexible members 74 through the nut 88.

Title: Improvements in colour television
IPC: H04N9/07
Filed: 1946-10-11
Abstract: 627,592. Television. COLUMBIA BROADCASTING SYSTEM, Inc. Oct. 11, 1946, No. 30448. Convention date, Dec. 13, 1940. [Class 40 (iii)] Colour television apparatus comprising an electronic scanning device by which an image area is scanned in a plurality of closely-adjacent parallel lines includes a rotatable colour filter element having a plurality of colour filter segments of different optical characteristics and positioned in the path of the image light to said image area so that the boundaries between the segments are substantially parallel optically to the parallel lines of the image area and said light passing through the segments during the rotation of the element undergoes a progressive change of colour at approximately the same speed as that of the movement of the scanned lines over said image area. In the arrangement shown in Fig. 1, the image of the object 10 is projected by a lens 11 on to a fixed mirror 14 inclined at an angle of 45 degrees to the axis of a drum carrying coloured filter segments 22 and rotated by a motor 25, the reflected image being focussed on to the transparent storage screen 15 of an orthicon tube having the normal deflecting coils 18, 19 and an axial field coil 21. The segments 22 are separated and supported by opaque strips 23 and the drum rotation is phased so that an opaque strip coincides with or includes the line being scanned and the exposure of the screen 15 to the subsequent colour image of the object follows up the scansion of the colour image stored on the screen. If the image is focussed approximately at the screen 15 of the orthicon, it will be out of focus at the drum periphery and the opaque strip 23 is made wide enough to prevent the simultaneous passage to the screen of image rays corresponding to the colours of two adjoining segments, as described in connection with Fig. 4 (not shown). In a modified arrangement, Fig. 5, using an iconoscope 39 at a relatively great distance from the drum 13 an intermediate image 35 is formed near the drum periphery and this image is focussed by a lens 36 on to the main screen 38. In the arrangement shown the axis of the drum is at right angles to the principal axis of the projecting lens 34, but the inclined mirror 14 is effective to deflect the image of the boundary between the colour segments to a direction parallel to the scanned lines on the screen 38. The mirror 14 may be inclined to the axis of the drum at an angle other than 45 degrees. The arrangement may be incorporated in an interlaced scanning system, a deflecting disc being used to shift the image for alternate scans or the scanning spot may be of dimensions such that in scanning one set of lines on the screen it also discharges the next adjacent or alternate lines so that these can be charged corresponding to the succeeding colour image and are subsequently scanned.

Filed: 1933-11-03
Abstract: 413,542. Separating leaves from bulk. THORNTON, A. A., 7, Essex Street, Strand, London.-(Gough Stemming Machine Corporation; 420, Lexington Avenue, New York, U.S.A.) Nov. 3, 1933, No. 30583. [Class 130.] A conveyer thrusts leaf masses on to a table, and a device having a finger or fingers is thrust into the leaf masses and then moved to carry such masses away from the table, the device being driven at such a speed that the finger or fingers act on each leaf mass several times to separate parts thereof from each other. An operator aligns a mass of tobacco leaves, or a bunch of leaves of a similar kind, against a plate 12 and places the stems on pins 3 carried by conveyer belts 1, 2 which are moved intermittently by a pawl 8 and ratchet 9, and the leaf blades are supported on belts 13, 14. Guide plates 48, 49 press the leaves on to the belts, 1, 2, and a rotating comb 44 straightens the stems before strippers 47 remove the blade material from the ends of the stems. The belts 1, 2 discharge the leaves on to an inclined portion 19 of a table 18, and subsequent masses thrust those previously delivered along a level portion 20 of the table, beneath a spring- pressed plate 21 which prevents the leaves from piling up. The blades of the leaves are discharged from the belts 13, 14 by a toothed wheel 23, and restrained from undue upward movement by a guide plate 24. Fingers 31, carried on belts 28, 29 which move more rapidly than the belts 1, 2, separate the stem ends of the leaves while the blades are carried by a belt 22, and the leaves are delivered to stripping-belts 36, 37, which are driven still faster, and are pressed together by a block 39, whilst belts 38 withdraw the stems from the leaves. In a modified construction, the stem ends of the leaves are separated by fingers mounted on a crossbar connected to a rocking lever, and are actuated so that they are thrust downwardly into the leaf mass, moved to pull a part of the mass from the remainder, and finally returned to their initial position, the cycle being repeated several times on each leaf mass.

Abstract: 454,816. Vibrating - apparatus for concrete and like surfaces. MOSER, F., 32, Dufourstrasse, Zollikon, near Z³rich, Switzerland. Nov. 5, 1935, No. 30619. Convention date, Nov. 5, 1934. [Class 107] Concrete and like materials are compacted by a continuously vibrating member 6 which is continuously moved over and parallel to the surface 3 to be obtained and which is so disposed that the line of action of the compacting force makes a constant angle of less than 90‹ with the surface. The member 6 may, as shown, be adjustably mounted upon a carriage 8 which moves along rails 9 disposed on either side of the surface 3. The member is pivoted at 10 to standards 11 and the free end is connected by a cable 12 to a winding drum 14. A number of holes are provided in the standards to provide for the adjustment of the pivotal end of the vibrating member, the inclination of which is varied by the cable 12. The inclination is preferably such that the upper end 5 of the member 6 extends to or above the upper surface of the material to be compacted; the vibrator is indicated at 7. The lower face of the member 6 may be plane, as shown, or it may have a number of faces of different inclination, or again, it may be curved. According to a further modification, the member 6 is V-shaped when viewed in plan. The Specification as open to inspection under Sect. 91 describes also a method of forming grooves in a concrete surface. Such grooves are formed by arranging beams or rods between the concrete surface and the vibrating member. The latter is set in a horizontal position and is moved along the beams or rods which are thus pressed into the surface. This subjectmatter does not appear in the Specification as accepted.
