Abstract: 485,877. Discharge lamps. SIEMENS ELECTRIC LAMPS & SUPPLIES, Ltd., and ALDINGTON, J. N. Dec. 8, 1936, No. 33675. [Class 39 (i)] The light from mercury or other metal vapour discharge lamps is modified by surrounding the arc, wholly or in part, by a sleeve of highly refractory material which becomes incandescent in use. Where the nature of the material does not provide sufficient translucency, the tube may be made in two parts each surrounding the arc near an electrode leaving the central part of the arc free, or it may be provided with a longitudinal slit or a number of slits in line for the unrestricted emission of light. The tube may be formed of magnesia, alumina, or rare earth oxides such as zirconia or yttria. Other materials providing selective radiation such as thoria with a small amount of ceria may be applied to the outside of the tube. As shown in the Figure, a lamp with a quartz envelope 1 and thermionic electrodes 2, is provided with a sleeve 4 enclosing the arc and sufficiently close thereto to become incandescent in operation.

Abstract: 618,723. Agricultural implements. POMIERANIEC, I., and TRANSPLANTERS (ROBOT). Ltd. Nov. 19, 1946, No. 34265. [Class 6 (i)] A wheel-operated toollifting device, provided on an agricultural implement, can be actuated by an operator so that the lifting mechanism can be driven in either direction, to raise or lower the tools, during the forward travel of the implement. In the form shown, a tool frame 4 carrying a plough 5 is pivoted about the axle of the land wheels 1 of a main frame 2 and is provided with a forwardly-extending lever 6 which is pivoted to the angle of a bell-crank lever 7a, 7c. One arm 7a of the bell-crank is pivoted to a link 8 attached to a rack element 9 which is pivoted at 12 to a crank 11. The rack element 9 is sector shaped and includes two sets of rack teeth, one set or the other being engageable with a pinion 13 driven by the land wheels. A third arm 7b, provided on the bellcrank, carries at its upper end a head slidable between springs 16, 17 on a rod 15 attached at one end to the crank. The crank 11 is also pivotally mounted and its upper end is held against a manually-operable latch 18. In Fig. 1 the tool is shown being raised by the interaction of the pinion 13 and the lower rack. As the pinion reaches the end of the rack the lever system 6, 7, passes through a dead-centre position and becomes locked in the angle of the lever 8 (Fig. 3). At the same time the head 14 slides along the rod 15 and compresses the spring 17. On releasing the latch 18, the rack element pivots under the action of the spring 17 and the pinion engages the upper rack. During lowering of the tool the head 14 compresses the other spring 16 so that the next release of the latch will result in engagement between the pinion and lower rack (Fig. 1). The device may be applied to all types of land-engaging implements (e.g. planting machines).

Abstract: 467,633. Valve gear. GENERAL MOTORS CORPORATION. Dec. 14, 1936, No. 34270. Convention date, Dec. 13, 1935. Addition to 464,612. [Class 7 (vi)] The hydraulic slackadjusting device comprised in the parent Specification is modified in that the valve device controlling the flow of fluid to and from the cylinder device is formed separately from, but abuts against, the thrust-transmitting member. The tappet comprises a hollow cylinder 30 in which operates a hollow piston 32, the space between them being filled with oil, which is replenished from passages 72, 70 leading to the space above the piston. When the tappet is resting on the inoperative portion of the cam as shown, the thrust-transmitting member 48 contacting with the stem 16 of the engine valve is raised from a central flange on the piston by a spring 46 acting through the valve device 40 having an extension 38 projecting through the piston flange. Oil then flows from above the piston through passages 44, 42 to replenish the space below the piston. When the cam is operative, the piston is forced thereby into contact with the valve disc 40, thereby shutting off the space beneath the piston. The oil above the piston is prevented from surging up the valve stem 16 by a flanged valve member 62 pressed upwards by a spring 66. In a modification, the supply ports 70, 72 for oil are omitted, and the oil draining through the valve member 62 is used for replenishing.
