Title: Improvements in and relating to electro-magnetic devices for controlling alternating current dynamo electric machines
IPC: H01F27/245
Filed: 1920-01-03
Abstract: 162,731. British Thomson - -Houston Co., Ltd., and Taylor, H. W. Jan. 3, 1920. Alternating - current induction machines.- The cores of apparatus for controlling alternating-current circuits of variable frequency in dynamo - electric machines bv the action of eddy currents, such, for instance, as those used in the rotor circuits of induction motors for starting, are formed of a number of relatively thick magnetic rings or plates. The three-phase form shown in Fig. 1 has cores A formed of four plates interleaved with end members B each having three plates of greater width than the cores A so that the exposed area per unit length of magnetic path is the same in the members A, B. Insulation is placed between the overlapping iron parts. The plates A may be thinner than those of the end members so that at high frequencies they can easily carry the flux carried by the thick plates but at low frequencies when the flux tends to become greater and more evenly distributed over the section of the thick plates the thin plates become saturated and restrict the flux and eddy losses in the thick plates. The plates may be made of materials of different penneabilities or conductivities or of " hard " magnetic material so worked that at the minimum current value in the coil they are at their maximum permeability so that increased current gives them an increased equivalent resistance. The cores may project from the coils without the provision of a salient iron closed return path for the flux and may consist of round, square or hexagonal bars of relatively thick material insulated from one another, as in Fig. 3<a>, or separated by air spaces. Alternatively, they may consist of tubes, used singly or grouped concentrically or, as shown in Fig. 3<c>, the tubes may be split longitudinally. In another form they may be made of triangular or other sheets rolled into spirals. Some of the core elements may be removable or thev may be of different lengths so that by moving the coils on the core they may act on different quantities of magnetic material to give different equivalent resistances. Arrangements may also be made for using different numbers of the coil turns. Fig. 4 shows a form having cores M made of split gas barrel on which the coils N are directly wound, any desired number of such elements being assembled by connecting them to split barrel endmembers P by pipe clamps Q. According to the Provisional Specification, the cores may be made of closed tubes or spirals of perforated or expanded metals and mav be embedded at their ends in slabs of Portland cement having meshes of magnetic material embedded in them.

Title: Improvements in or relating to photographic exposure controlling means
Inventor: CLARK GEOFFREY
IPC: G03B7/00
Filed: 1955-01-05
Abstract: 775,704. Photographic cameras. KODAK, Ltd. Jan. 3, 1956 [Jan. 5, 1955], No. 314/55. Class 98(1) In a photographic camera, the exposure is controlled by manually operating the diaphragm aperture adjusting means, the shutter speed adjusting means being controlled thereby through a lost-motion connection so that when the opening in the diaphragm is increased beyond a predetermined size the speed of the shutter is decreased. In the form described, the predetermined aperture size corresponds to the maximum aperture of the lens and the further increase in size of the opening in the diaphragm does not change the aperture of the lens but merely increases the exposure by lengthening the exposure time. The diaphragm operating ring carries a light value scale so that the diaphragm aperture can be increased with decreasing light at the faster speed of a two-speed shutter and the final movement of the ring sets the slower speed of the shutter. When the diaphragm is returned from the position of maximum aperture, spring 40 turns an annular rotatable plate' 34, by means of a pin 41 thereon, so that cam surface 36, carried by the plate, is positioned beneath an extension 46 on a lever 19 (Figs. 4 and 8). The shutter is then arranged to give the shorter of its two exposure times. On turning lever 16 anticlockwise to release the shutter, the end 24 of lever 19 rides up the curved edge of lug 33 and falls down to engage the front of the lug. When lever 16 disengages from lever 19 (Fig. 4) spring 21 turns lever 19 anticlockwise about pivot 20 to open the shutter blades through engagement of pin 25 on the blade ring (not shown) with members 27 pivoted at 28. The disengagement of end 24 of lever 19 from lug 33 and the return of the blade ring under spring 29 to close the shutter is effected rapidly in Figs. 4 and 8 by extension 46 riding up cam surface 36 and lifting the end 24 clear of lug 33. The engagement is prolonged in Fig. 7 by the necessity of imparting motion to weighted member 31 through arm 38 before the tip of end 24 is clear of lug 33. Plate 34 is turned to the position shown in Fig. 7 by the lost-motion connection between lug 43 on the reverse side of the plate and a pin (not shown) on the diaphragm operating ring.

Abstract: 193,358. Dyhrberg, L. N. Aug. 18. 1921. Stream-cutting machines.-In a brick-making machine of the type ir. which the stream of clay from the pug mill is utilized to set in action the cutting-mechanism, the extruded clay bar is severed instantaneously by a cutter mounted at one end of the travelling cutting-table and operated by stored-up energy. The cutter comprises a frame 102 pivoted between the jaws of a forked bracket 104 attached to a frame 27 which supports the cutting-table 22, and a wire 103 mounted between upper and lower bars, the latter working in a guide 22b in the table 22. The cutter is operated by springs 109, 112, Fig. 4, joined by a lever 108, the spring 112 being attached to an adjustable hooked bolt 113 while the spring 109 passes over a pulley 111 and is attached to the frame 102. The cutter is maintained in its set poeition by a pivoted catch 114, Fig. 5, held normally in position by a spring 114<a>, and is released by the pull of a chain 117 displacing the catch from its locking position. The chain 117 is attached to the frame cf the cutting-table, and is tightened owing to the forward motion of the table, under the pressure of the clay bar. The cutter is reset by the plunger 29 which pushes the severed bar through the brick-cutting wires 28, engaging in its forward movement the frame 102 by means of a projection 29a. The severed bar is held in position and partially divided by knife blades 173 which correspond in number and position with the cutting-wires 28. The blades 173 are sus pended from a bar 174 pivoted in bracket 175 and are operated by a stud 178 on the frame 102 striking against the downward-turned arms of a fitting 177 mounted in the bar 174.
