[Also in Group XXXV] A magnetic core for saturable inductors, magnetic amplifiers or like controllable devices has a portion which is of reduced cross-section compared with the remainder of the core. The core at this part may be of smaller dimensions or, if the core is laminated, the parts of some of the laminations may be omitted. In this latter case the core may be built up of two kinds of laminations each kind having different magnetic properties, one kind, having a rectangular hysteresis loop, forming the part having the reduced cross-section whilst both kinds form the remaining portions of the core. The other kind of lamination has a normal type of hysteresis loop. The core may also be constructed of magnetic ferrites in which case the part of the core with a reduced cross-section may be in the form of a tapered pin which is inserted after the coil windings have been assembled with the main part of the core. In another embodiment the magnetic properties of the core portion having the reduced cross-section may be further varied by mechanically applying pressure thereto, and further the laminations not forming the part having a reduced cross-section may be slotted in the flux direction.

Abstract: 822,322. Oil filters. COMPRESSOR & POWER ENGINEERS Ltd. Feb. 27, 1956 [Nov. 25, 1954], No. 34150/54. Class 46. [Also in Group XXVIIII In an oil filter, a cylindrical block 1 with recessed sides 27, 27a, houses a rotary plug cock 22 formed near its ends with oppositely directed L-shaped passages 36, 37 and at its middle with an annular groove 38. The passage 36 registers with either of opposed passages 34 in the block each leading into a space between a cup-shaped cover 14 and a filter sleeve 11. Similar passages 35 co-operate with the passage 37. Intermediate transfer passages 8 connect the annular groove 38 through spring pressed valves 18 with the interiors of perforated tubes 6 within the sleeves 11 but extending through end plates 12 thereon to receive screwed nuts 13, 15 by which the sleeves 11 and covers 14 are secured in place. End caps 16 on the tubes 6 engage the stems of the valves 18 to open them when the caps are screwed down. Removal of a cap permits the corresponding valve to close and stop the flow of liquid in the associated filter unit. In the recess 27a are mounted an inlet nipple 28 and a main discharge nipple 30 communicating respectively with the passage 36 and groove 38 ; the passage 37 communicates with an auxiliary discharge nipple 32. In operation, with the plug 22 set by its handle 25a as shown, liquid to be filtered entering at 28 flows through the passages 36, 34 into the filter 5 between the cover 14 and sleeve 11, through the sleeve into the tube 6 and thence past the valve 18 into the transfer groove 38 in the plug 22. Here it divides, most flowing back into the liquid circulation system but part passing through the other filter 4 in reverse flow under control of a restricted orifice in the auxiliary discharge nipple 32. On reversal of the handle 25a, the filter 4 functions normally and the filter 5 is cleansed. If the liquid from the cleansing operation is to run to waste, the plug 22 is shortened, the passage 37 omitted and discharge from the reverse flow effected through a drain plug. In both forms the passage 36 may be made T-shaped to permit both filters to act simultaneously or alternatively as desired.

Patent GB-342424-A (GB)
Abstract: 342,424. R÷ntgen-ray apparatus- NAAMLOOZE VENNTOOSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13A, Emmasingel, Eindhoven, Holland. Nov. 22, 1929, No. 35873. Convention date, Nov. 24, 1928. [Class 98 (i).] In an apparatus for taking stereoscopic X-ray photographs, a single ray-tube is mechanically connected to a holder for one or more photographic plates or films in such a way that a displacement of the holder through a distance equal at least to the length of the image to be taken is accompanied by the displacement of the ray-tube necessary for a stereoscopic photograph. The two displacements are preferably in the same direction. In one form, the ray-tube carrier and the film holder are connected by a cord or chain passing over pulleys. In another form, the ray-tube is mounted on arms 10, Fig. 3, on a carriage 8 running on rails 9, and the film holder 12 is mounted on rods 14 slidable in guides in a fixed casing 11 provided with an aluminium exposure window shown chain-dotted. Springs 15 on the rods 14 tend to urge the film holder in the direction of the arrow ; but in the position shown, for taking the first picture of the pair, the holder 12 is held against displacement by the engagement of a lug 17 thereon with a pawl 16 on the casing 11. To move the parts into position for taking the second picture, the carriage 8 is displaced in the direction of the arrow ; a cam 18 thereon trips the pawl 16 and frees the film holder, which is displaced by the springs 15 until a projection 22 engages a catch 23. Buffer springs 20 absorb the shock when the carriage 8 is arrested by the stops 25 striking the ends of the rods 14. Recesses may be provided in the rails 9 to ensure that the carriage 8 shall rest in the correct terminal positions. The parts are returned to the initial position by pulling a cord 24 attached to the film holder. In a further form, the ray-tube 30, Fig. 4, is carried by arms 32 on a framework 31 rotatable about a spindle 33 in the plane of the sensitive film holder 34. Simultaneous displacement of the film holder in the direction of the arrow, and rotation of the ray-tube carrier into the dotted position, for taking the second picture with the second film in the same position as the first, is produced as by mechanism similar to that shown in Fig. 3, or by means of a lever system.
