Abstract: 196,315. Adair, J. Oct. 26, 1921. Lateral-splash guards.- A canvas splash-guard G, Figs. 1 and 2, riveted on arms or members 7, on coming in contact with the curb. pivots in seats 8 at the end of an arm C, and stretches a spring, indicated by dotted line S<2> ; this tension causes the arm C to pivot about a pin 12 mounted on the end of a spring-plate B fixed to an unsprung part of the vehicle, thus lifting the guard so as to ride on the top of the curb. A counterweight 4 and cords F prevent excessive movement of the guard. The plate B extends to the opposite side of the vehicle, and there supports a similar guard. The members 7 may be extended, as indicated by dotted lines 10, and curved inwards. The members 7 may be constructed of tubes, Fig. 9, with coil springs S projecting from them fitting in members riveted to a bar D which is riveted to the member C; these members 7 can be turned to offer different wearing faces to the curb. The members C, D may be constructed in one piece of aluminium &c. Fig. 9 also shows a modified form of attachment to the vehicle, allowing of vertical adjustment by placing packing-strips between the spring arms B and a bar B<2>. A tightening-bolt is provided at one end of the canvas splash guard. Strong springs are provided in the terminal arms 7, Fig. 9, to operate the lifting of the guard and weaker centre springs to prevent flapping. A further modification is shown in Fig. 14, in which a thin band x passes through a slot in the arm C, the movement of the arm C being limited by rubber stops 3 and a spring 21 and a tooth 22, Fig. 17, controlled by a spring indicated by a clotted line 29, this spring device being mounted in a casing y adjustable along the arm C.

Title: Device for the emission of coherent radiation
IPC: H01S3/213
Filed: 1971-04-19
Abstract: 1323621 Lasers WESTERN ELECTRIC CO Inc 19 April 1971 [26 Jan 1970 21 Dec 1970] 20155/71 Heading H1C [Also in Division C4] A stimulated emission device has a fluid active medium such as a dye or a Raman liquid, and is pumped by monochromatic light supplied by a filamentary dielectric member having a transverse dimension in the range 1-100 times the wavelength of the pumping light. This member may be a capillary tube containing the fluid or may be an optical fibre passing through the fluid. Fig. 1 shows a Raman fluid in a capillary tube pumped by an argon laser 13. A resonator is formed by reflectors 14 and 21 with lenses 15, 20. The reflector 14 passes the pumping light to lens 15 which focuses the light into the tube bore; both the pumping light and the stimulated Raman light are internally reflected along the tube. Because the fluid is damaged by pumping it is flowed through the tube, though the mass flow rate is small because the tube is narrow. Radiation may be directed into the tube, and out of it, by optical pins which fit into the tube ends; the resonator reflectors may be mounted on these pins, Fig. 2, and their inner ends may be shaped for mode selection. Fig. 2 also shows a dispersive prism and movable mirror 33, 34 which allow any one of the Raman shifted outputs to be selected. In Fig. 4 the tube is coiled, and the device is used to amplify a signal from source 48 of frequency equal to one of the Raman shifted outputs. If the beam splitter 47, source 48 and reflector 49 are omitted the device may act in a super-radiant manner, i.e. without a resonator. The multiple frequency outputs obtainable may be used in a frequency-multiplexed transmission system, and several tubes containing the same or differing fluids may be joined by shaped pins, Fig. 5 (not shown). An alternative construction is shown in Fig. 6, where the pumping light is fed into the fluid by a light fibre 63 whose refractive index is very slightly above that of the fluid. Some of the pumping light is scattered into the fluid, and similarly some of the Raman light enters the fibre and is guided along it. The fibre may be mounted under tension to keep it straight, or may be supported on a thin member of the same refractive index as the fluid, Fig. 8. For laser operation, Rhodamine 6G in air saturated ethanol is preferred; however even this bleaches rapidly and fluid flow is essential. The arrangement of Fig. 8 allows a minimum flow rate to be used, and a continuous laser output is possible. Raman media.-Suitable media, with their refractive indices n and with the shift they produce in incident light are:

Abstract: 869,469. Railway vehicle undercarriages. KRAUSS-MAFFEI A.G. June 27, 1957 [Nov. 27, 1956], No. 20307/57. Class 103(6). In a rail traction vehicle either of the bogie or rigid frame kind, e.g. locomotives, and in which two or more wheel sets are driven, resilient members which are operative in the longitudinal direction of the vehicle are interposed in the axle suspension of at least one of the driven wheel sets, the spring rate of the resilient members being such that at any driving power the quotient of the tractive force produced by each wheel set divided by the aggregate spring rate the axle suspension, is substantially equal for all wheel sets. As shown in the embodiment of Fig. 9, the end wheel sets 1, 3 of a rail vehicle bogie having driven wheel sets 1, 2, 3, are suspended by the bogie frame 7 by guide arms 18 connected to the frame through prestressed rubber bushes or sleeves 12 whilst the central wheel set 2 is mounted in the frame through the agency of conventional sliding guides, plate-like rubber and metal elements 11 being interposed between the axle boxes 19 and the vertical axle box guide surfaces. The bushes or sleeves 12 and the elements 11 each have the same spring rate longitudinally of the vehicle and since the wheel sets are driven from a single motor (not shown) the tractive force at each wheel set is equal and thus the quotients, tractive force divided by spring rate, for each wheel set, are equal. The members 11 each have a metal plate 20 abutting the axle guide surfaces and a metal plate 21 facing the axle box 19. In other embodiments different tractive forces are produced by the respective wheel sets and the aggregate spring rate of each of the axle suspensions of the wheel sets is proportional to the tractive force produced by the respective wheel set. The resilient members may be interposed in some instances between the wheel frame and a bogie pivot pin on at least one bogie. The spring rates of resilient members interposed in the axle suspension of a wheel set may differ for opposite directions of travel of the vehicle.

[Class 34(ii)] A tumbler-type clothes drier has a lint trap which comprises a screen intercepting the fan discharge air stream, the screen being inclined forward into the air stream, and a bye-pass passage over the forward part of the screen. As shown, the air intake of a fan 28 of a tumbler drier has an axially extending duct 21 which communicates through openings 23 in its side walls with the wrap around sheet which encloses the periphery of the tumbler drum and has openings 24, the front end of the duct having a clean out cover 25. The fan casing has a discharge nozzle 30 fitting into a lint trap 31, extending across the side walls of which are screens 32, 33, 34 which intercept the air stream. Each of the screens has a section 34a inclined forwardly into the air stream and between the forward edge of the screen and the adjacent walls of the line trap is a byepass passage 35 through which the air flows when the filter screen is clogged, the screens being staggered so that the air does not flow through the bye-pass until the screens are clogged. The top wall 36 of the lint trap is held in place by a spring 37 but may be opened to clean out the trap when the latter is removed. A thermostat bulb 42 projects through a wall 43 into the discharge nozzle 30 in the direction of the air flow, the velocity of the air being sufficient to prevent the adherence of lint to the bulb.
