Abstract: 1,000,416. Water - cooled slag scrapers. GEBR. BOHLER & CO. A.G. Nov. 14, 1961 [Nov. 19, 19 No. 40731/61. Heading F4B. A water-cooled slag scraper includes a hollow blade in which passages are formed, the passages being interconnected in series and all or substantially all the water used to cool the blade flowing through each passage. The scraper also includes a handle (not shown) and a hollow shaft. The shaft shown consists of two tubes 9, 10, the tube 10 being extended to form the scraper handle. In use, water enters the scraper blade by way of tube 9 and flows successively through passages defined by walls 4-7 to an outlet connected to the tube 10. The scraper shown is formed from plates or strips welded together. A further form of blade consists of square or round tubes welded together to provide passages connected similarly to those shown. The blade may alternatively comprise a tube coil, Fig. 5 (not shown), having the spaces between the tube portions filled in with welding material or with welded-in material.

Abstract: 993,382. Folding paper. EASTMAN KODAK CO. Oct. 16, 1963 [Oct. 22, 1962], No. 40780/63. Heading B6H. A zig-zag folded web F is passed through processing apparatus 13 and re-formed into a zig-zag folded pack by means of a receiver 51 of resilient flexible material which presents a concave surface for receiving the web and is sufficiently flexible so that as the weight of the web received on the concave surface increases the surface is progressively flattened. The receiver comprises a plurality of spaced strips 55 riveted to a base plate 53. The latter rests on a triangular support 59, attached at its three corners to screw rods 71. A motor M rotates the screws in unison whereby the receiver is progressively lowered to maintain the top of the pack a constant distant from delivery rollers 21, 23. Pivoted guides 29, 31, counterweighted at their upper ends, are initially positioned adjacent each other to form a throat directing the leading edge of the web towards a plate 41, Fig. 4 (not shown), when the first fold in the web occurs as shown in Fig. 1. As more of the web passes on to the guide 31, the latter pivots away from the plate 41 until its counterweight swings it into the inoperative position shown. Should the first fold in the web be in the reverse sense, then the guides are initially positioned to direct the leading edge of the web towards plate 43.

Title: Improvements in or relating to waveguides
Inventor: CHIRON BERNARD PIERRE
IPC: H01P1/397
Filed: 1959-12-08
Abstract: 880,372. Waveguide circulators. LIGNES TELEGRAPHIQUES & TELELEPHONIQUES. Dec. 8, 1959 [Jan. 19, 1959], No. 41701/59. Class 40(8). A four-port circulator comprises two parallel waveguides 1, 2 coupled by four identical directional couplers 7, 8, 9, 10 which are designed to cause complete transfer of energy from one waveguide port to another, the waveguides being loaded with a pair of non-reciprocal ferrite phase-shifters 12, 13 and a pair of dielectric member 11, 14. It can be shown that complete energy transfer is achieved if each of the couplers has a coupling factor equal to sin a where a=22¢ degrees. For propagation from left to right, the ferrite elements 12 and 13 are arranged to cause phase-shifts respectively equal to the phaseshifts caused by dielectric elements 11 and 14. Thus, input energy applied at the port 3 appears entirely at the port 6. For propagation in the opposite direction, the phaseshifts caused by the ferrite elements 12 and 13 are respectively 180 degrees greater and 180 degrees less than the phase-shifts of the corresponding dielectric elements 11 and 14. This results in a relative phase reversal of the waves combining at the couplers 9 and 7, and consequently in the total transfer of energy from port 6 to port 5. In the embodiment shown, the couplers are constituted by apertures in the common narrow wall of rectangular waveguides 1, 2. They are spaced apart by a distance greater than half a wavelength. The non-reciprocal phase-shifters 12, 13 comprise slabs of low-loss ferrite asymmetrically arranged parallel to the narrow walls of the waveguides and subject to transverse magnetic fields provided by permanent magnets 31, 32. The port 4 may be terminated by a matched resistance.

A screw impeller (not shown) disposed in a housing 1 feeds wet and pulpy material through members 2 and 3 past a displaceable shutter 4 so that it can be acted on by pressure air supplied through an annular nozzle 5 and thence to a pipe line 8. When the pressure in the vicinity of the nozzle 5 reaches a predetermined degree, a mechanism 17 actuates a switch 19 to energize a motor 12. This acts through a drive 10 to rotate the shutter 4 so as to prevent the feed of further material. When the pressure again subsides, the mechanism 17, 19 actuates the motor 12 so that it rotates in the reverse sense to move the shutter 4 into the open position. A pinion 11 on the motor shaft operates cam members 21a and 21b which co-operate with limit switches 23, 22, so as to de-energize the motor 12 at either extreme of its movement. If desired, the mechanism may be arranged to switch-off the motor driving the screw impeller when the shutter 4 is moved to its closed position.
