Title: Improvements in or relating to vehicle direction indicators
IPC: B60Q1/36
Filed: 1947-07-10
Abstract: 650,727. Road-traffic signals on vehicles. O'SHEI, W. E. July 10, 1947, No. 18235. [Class 118 (ii)] A vehicle direction indicator of the semaphore arm type is provided with a mechanical latch for holding the indicator arm in its displayed position so that the holding current may be reduced or eliminated, the latch being alternately engaged and released by successive energizations of the operating means. In the preferred embodiment a rhomboid-shaped latch 15 is pivoted at 14 to the core 7 of a solenoidoperated indicator of the type described in Specification 635,067. In the position shown the latch 15 engages the step 16a of the stop 16, preventing the upward movement of the core 7 and hence holding the arm 4 displayed. On subsequent energization of the solenoid 6 the core 7 is drawn downwards and projection 19 turns the latch 15 so that on de-energization of the solenoid the core is free to rise fully and allow the arm 4 to fall to its unoperated position. On the next energization of the solenoid the lower tip of latch 15 rides down the ramp 18 till it meets the projection 19, thereby bringing the upper tip under the stop 16 such that on de-energization of the solenoid the latch is again engaged by 16, 16a and holds the mechanism in the position shown. Figs. 2 to 7 (not shown), indicate various stages in the functioning of the latch. The contacts 20, 21 constitute an automatic switch to operate the indicator after initiation by momentary contact at the manual switch 30: When the switch arm 34 is rotated to one side of its normal vertical position solenoid 6 is energized, the magnetic member 28 is drawn upwards and contacts 20 and 21 make to continue the energization of the solenoid after switch arm 34 has passed to its non-contacting position shown. At the bottom of its travel the core .7 pushes the member 28 so as to break contacts 20, 21, de-energize the solenoid and allow the latch to lock the indicator in its display position. A similar sequence occurs when the switch 34 is returned to the vertical but this time the latch is turned to allow the indicator to revert to its non-displayed position.

These seals extend radially to permit relative radial thermal expansion between the stator and rotor. The rotor blades are preferably hollow and have dovetail roots located by the rings 75, 76 in correspondingly-shaped transverse slots in the rotor disc rims. A tapered hole is provided in the rim between each pair of transverse slots for weight reduction. Cooling gas passes through holes 92, 23, 25 in a double-walled cylindrical or frusto-conical casing 6, thence through apertures 37 and the interiors of hollow sheet-metal stator vanes 35 into spaces between and adjacent the rotor discs, and finally discharges through holes 94, 95 in the hollow shaft and holes 96 in bearing support disc 32. The latter is bolted to a ring 31 connected to a diffuser wall 29 by tangential struts 30. The hollow shaft is formed by axial extensions of the rotor discs welded together at 55 or connected by splines. Each rotor disc comprises two parts welded together at 50, 51. An oil pump 15 delivers lubricating oil to engine bearings via hollow pump shaft 61 and hollow rod 62.

Filed: 1921-07-06
Abstract: 182,325. Hoffmann, A., and Kommandit-Ges. Hoffmann & Co. July 6, 1921. Cylinder machines; tripping-arrangements; bedreciprocating apparatus.-A machine for printing letters in imitation of typewriting comprises a reciprocating bed 5 provided with an ink ribbon 18 over its forme, the bed being reciprocated by a roller on an endless chain 6, and being formed with a projection 19 which actuates a wedge 3 so as to depress the bed out of action after an impression has been taken. The bed 5 is mounted on rollers 4 supported by the wedge 3, and in the position shown, the bed is nearing the end of its idle stroke to the left which is effected by a projection 10 on the chain 6 acting on a projection 11 of the bed. At the completion of this movement of the bed, the projection 19 acts on an arm 12 on the wedge 3 and raises the bed to printing position. A sheet is then fed from the table 14 to the bed, and as the bed is moved to the right by the action of the chain on a projection 13, printing occurs owing to the sheet being gripped between the impression cylinder 17 and the bed. At the end of this movement, the wedge 3 is moved to the right by the action of projection 19 on an arm 20 of the wedge, and the printed copy is detached. The actual printing pressure may be varied by adjusting the position of a lower wedge 2, on which the wedge 3 rests, by means of an arm 22 which is adjustable over a segment 25 and has a pin-and-slot connection with the wedge 3.

Abstract: 452,813. Fluid - blast switches. SIEMENS SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. June 26, 1935, No. 18321. Convention date, Aug. 31, 1934. [Class 38 (v)] An arc-extinguishing device consists of a double nozzle which directs a current of compressed gas delivered at a central position between the nozzle openings in two directions axially towards the ends of the electrodes between which the arc is drawn. The gas is conveyed between walls of insulating material in which the double nozzle is formed and the distance apart of the nozzle openings is restricted to an extent such that the zone of low gas velocity located centrally between the openings is restricted to a minimum. The contacts are withdrawn in opposite directions along the axis a-a from a pair of nozzle openings 3, 4, which are coaxial with a-a and formed in the insulating walls 1, 2 of a channel by which the fluid is delivered, from all sides. A pair of ring-shaped members 10, 11 are inserted in the channel to restrict its cross-section in the neighbourhood of the nozzles, the resulting flow-lines being, as shown at 12, caused to penetrate as far as possible towards the axis a-a before being deflected at right angles, so restricting the cross-section of the arc at that point. In Fig. 4, the walls 14, 15 of the channel 13 are conically restricted, and the nozzle openings 16, 17 may be flared as shown in dotted lines. A contact 19 takes the arc when 18 moves out of engagement with the contact 20. The cross-section of the channel 13 is made equal to, or smaller than, the combined cross-sections of the nozzle openings. Arc resistant material such as steatite, carbon, slate, or tungstencopper alloy is used around the nozzle orifices in the restricted portion.
