Title: Electrically controlled warning signal installations for railway crossings
IPC: B61L29/28
Filed: 1935-04-16
Abstract: 444,048. Level - crossing signals. DEUTSCHE WERKE KIEL AKT.-GES., 114, Werftstrasse, Kiel, Germany. April 16, 1935, No. 11789. Convention date, May 16, 1934. [Class 105] An approaching train switches in a flashing signal at a level-crossing which remains in operation till the train has passed the crossing but such signal is not operated by a receding train as the dropping of the short-section track relay E, which is influenced only by the axle shunt, is rendered ineffective by a relay S which is energized over the train axles while in such section, the circuit for the relay S having been prepared by a stick relay V which was picked up when the train energized a relay A at the crossing. A train approaching the crossing from the left-hand side on entering the short section G<1> de-energizes the relay E so that a back contact e thereof picks up over a back contact s<2> of the relay S a relay U which then sticks over its contact u<1>. The flashing red lamp Lr is thus energized over a front contact u2. When the train reaches the crossing section G<2> the relay A is energized over the train axles, so that a contact a<1> thereof breaks the stick circuit of the relay U but picks up the stick relay V ; the flashing red lamp Lr continues to be energized but now over a front contact a<2> until the train has left the crossing section G<2> whereupon the flashing white lamp Lw is energized over the back contacts a<2>, u<2>. The receding train on entering section G<3> de-energizes the relay E but the closing of the back contact e thereof is ineffective since the back contact s<2> is at the same time being opened by reason of the relay S being energized over the train axles in the section G<3> in series with a front contact v<2> of the stick relay V ; the opening of the back contact s<2> de-energizes the stick relay V but the relay S, having now closed its own stick contact s<1>, continues to be energized so long as there are train axles in the section G<3>. When the train has left the section G<3> the apparatus returns to the normal state. The flashing of the lamps is effected by contacts cw, cr of relays Cw, Cr energized in parallel with the lamps Lw, Lr. A modification in which casual bridging of the rails at the crossing is ineffective to operate the relay A has a front contact of the relay U provided in a pick-up circuit for the relay A.

Title: Improvements in or relating to apparatus for effecting the lighting and extinguishing of gas burners from a distance
IPC: F23Q21/00
Filed: 1923-05-02
Abstract: 197,931. Minaux, P. May 17, 1922, [Convention date]. Closure members; fluid - actuating mechanism; valves controlled from a distance.-In a device for lighting and extinguishing gas burners by variations in the supply pressure, shown in the closed position, an increase in pressure from the supply pipe 1 will raise the counter-balanced bell 5, the lower end of which dips in glycerine &c. 19 in the casing 2, and with the bell the tube 6 is raised so that its lower end is clear of mercury in the cap 7, permitting gas to pass by way of the tube 9, perforations 10, bell 5 and tube 6 to the burner 3, where it is ignited by a by-pass 17. The rise of the tube 6 and bell is limited by a collar 18. The counter balancing arrangements comprise a forked lever 11 pivoted at 12, of which one arm 15, carrying a fixed weight 16, is substantially vertical in the " shut " position while the other arm 13 with weight 14, adjustable by screwing, is substantially horizontal. In consequence of this arrangement, the weight 16 is more effective in the " open " position, and hence a reversal of the operations does not occur on a return to normal gas pressure, but only on a distinct lowering of pressure below normal. In the Specification as open to inspection under Sect. 91 (3) (a) it is stated that the counter weights may be suspended by chains &c. passing over pulleys and also that the operations may be inverted to secure the lighting of the burners on a reduction of pressure, for example by supplying the gas outside the bell. This subject-matter does not appear in the Specification as accepted.

In a change-speed gear for a motor vehicle wherein steps 72, 74, 76, 78 of countershaft gear clusters 64 respectively mesh input, intermediate, low and reverse gears 52, 80, 82, 84 which are selectively connected to an output shaft 30 by an axially movable sleeve 142 having external and internal splines 174, 172 engageable with internal splines in the gears 52, 80, 82, 84 and external splines 86, 88, 90, 92 on the shaft 30, synchronizing and balk means 32 prevent the splines 172 engaging the shaft splines 86, 88, 90, 92 until the speeds of the sleeve 142 and shaft 30 are synchronized. Conical friction synchronizing rings 136, 138 carried by a hub 100 which is splined on the output shaft 30 are urged by waved springs 156, 158 into light frictional engagement with a drum 140 fast with the sleeve 142. Interengaging cam teeth 128, 154; 130, 156 between the hub 100 and friction rings 136, 138 produce a torque responsive axial engaging force on the rings. Radial pins 124 carried by the hub 100 ride up cam surfaces 122 on the shaft 30 during axial movement of the hub and the outer conical ends of the pins axially separate the rings 136, 138 to disengage the synchronizing clutch during ratio shift. Balls 106 carried by the hub 100 engage between the splines 102 on the shaft 30 and during ratio shift the balls engage recesses 108, 110, 112 in the splines to prevent axial ratio establishing movement of the sleeve 142 until the speeds of the sleeve 142 and shaft 30 are synchronized. The splines 174 and internal splines on the gears are longer than the splines 172 and shaft splines 86, 88, 90, 92 to permit engagement between the gears 52, 80, 82, 84 and sleeve 142 prior to engagement between the sleeve 142 and shaft 30. The step 78 of the gear cluster meshes the gear 84 through a reversing idler 94. The gears have double helical teeth to avoid axial thrusts and three equally spaced gear clusters 64 support the gears 80, 82, 84 without bearings. The input shaft 10 is driven from a main clutch (not shown). Operation.-During ratio shift the hub 100 and sleeve 142 are moved axially by a shift rod 162. Initial axial movement of the hub 100 and sleeve 142 disengages the splines 172. 174 from the shaft 30 and gears 52, 80, 82, 84 whilst the pins 124 ride up the cams 122 to disengage the synchronizing clutch. Further axial movement to establish a new ratio initially engages the splines 174 with one of the gears 52, 80, 82 84 and the pins 124 move into the next recess 114 or 118 in the shaft 30 whereupon the synchronizing clutch is engaged and rotates the hub 100 relative to the shaft 30. Thereafter the balls 106 move into one of the recesses 108, 110, 112 to prevent further axial movement of the hub 100 and sleeve 142 until the speeds of the sleeve 142 and shaft 30 are synchronized. When synchronism occurs final movement of the sleeve 142 engages the splines 172 with one of the shaft splines 86, 88, 90, 92 to establish the new ratio.
