Title: Gas lighter
IPC: F23Q2/28
Filed: 1971-04-19
Abstract: 1278918 Gas lighter ZENZA BRONICA KOGYO KK 19 April 1971 [13 Feb 1970] 22269/71 Heading F4F [Also in Division H2] A gas lighter includes an operating device 1 for lighting which is pivotable about a vertical axis in a horizontal plane, assuming main body 7 of the lighter to be held vertical, and which on rotation about the pivot crosses the extended path of discharging gas from a nozzle 10. When the operating device 1, which also serves as a cover, is rotated by thumb pressure on a pressing portion 1<SP>11</SP> against the tension of spring 5, it actuates both the gas discharge and ignition systems. An inclined cam 13<SP>1</SP> of a sliding projection 13 formed on the underside of the device 1 depresses a projecting rod 12 connected to a lever 11 which acts to open a valve connected to the gas discharge nozzle 10. Simultaneously a cam 4 is rotated so as to lift and then release a hammer 6 which returns by tension of a spring 9 to strike a piezo-electric element 14, generating electricity which discharges between an electrode 15 and the nozzle 10, lighting the issuing gas. Projection 1r engages stopper 1s to control the maximum rotation of the device 1 and edge portion 7r of the pressing portion 1<SP>11</SP> engages stopper 7s to prevent the device from being actuated accidentally.

Title: Method of improving gas distribution in bubble-cap towers operating with fluidized solids
IPC: B01J8/30
Filed: 1951-09-28
Abstract: <PICT:0700039/III/1> In the countercurrent contacting of downflowing fluidized solids (e.g. catalyst) with upflowing gases in a series of superimposed zones, wherein the zones are separated by bubble cap trays supporting dense layers of fluidized solids, and the solids pass from one tray to a lower tray 20 by a downcomer 24, gases are passed into the dense layer on the lower tray at a plurality of spaced distances above the tray in the vicinity of the downcomer. The gases flow into series of tubes 27, 28, 29, and out through openings 30, 31, 32 which may decrease in size from the bottom to the top. The density of the solids near the downcomer is reduced, thereby minimizing the density gradient and gas sweepage across the tray and increasing the uniformity of contacting.  In addition the bubble cap passageways may be restricted at the centre of the tray and near the weir 25 so as to permit more gas to flow near the downcomer.

Patent GB-388025-A (GB)
Title: Improvements in or relating to starting gear for internal combustion engines
IPC: F02N5/04
Filed: 1931-08-14
Abstract: 388,025. Turning-gear. TROTMAN, E. W., Shipyard, Littlehampton. Aug. 14, 1931, No. 22974. [Class 7 (v).] An engine starter comprises coaxial wheels 11, 16 serving together as a flywheel, the wheel 11 being fast upon or geared to an engine shaft 12 and connected to the freely rotatable wheel 16 by a spiral spring 22. The spring is stressed to a predetermined extent upon the starting of the engine, and the wheels are locked to rotate as one, when the spring is fully wound or unwound, by automatic means which can be released at will to allow the spring to restart the engine. The wheel 16 has mounted thereon a heavy ring 20 and rotates upon a ball bearing 15, the wheel and the bearing being retained in position by a cap 17 secured to the bearing member 14 by a stud 18. A flanged member 19 mounted on the wheel 16 provides a channel around which a rope may be wound for effecting a first start by hand. The spring 22 is attached to the ring 20 of the wheel 16 by means of a double link 23 pivoted at 24 on the ring, and the inner end 25 of the spring is similarly attached by means of a double link 26 to the bearing member 14, a pin 27 extending through both side members of the link 26 and through a bore in the member 14 and being keyed or otherwise caused to move as one with the side members of the link. The wound and unwound positions of the spring and the links 23, 26 are shown in full lines and in broken lines respectively in Fig. 2. The outer end of the pivot pin 27 is formed with a transverse groove 30 for engagement with a tongue 33 on a plunger 31 slidable in a bore 32 in the bearing member 14 ; and mounted on a reduced portion 34 of the plunger 31 in a pawl 35, normally in engagement with a ratchet notch 40, Fig. 3, in a flange 41 integral with the wheel 16. To start the engine, the plunger 31 is retracted, against a compression spring 42, freeing its tongue 33 from the groove 30 of the pin 27, and is turned in an anticlockwise direction as seen in Fig. 3. The pawl 35 is thus moved axially out of the notch 40 and turned into the position shown in Fig. 4. The spring 22 sets the wheels 11, 16 in rotation, but the wheel 11 is soon arrested by engine compression ; the momentum imparted to the wheel 16 will continue the unwinding of the spring until the links 23, 26 are in the position shown in full lines in Fig. 2, when the momentum of thewheel 16 will be transmitted through the wheel 11 to the engine shaft 12. The arrival of the links in this position brings the groove 30 into register with the tongue 33 of the plunger 31, the re-engagement of which is effected by the spring 42. When the engine starts, the wheel 11 will wind up the spring, returning the link 26 and the pawl 40 to the angular position shown in Fig. 3, so that the pawl can return axially into engagement with the notch 40 and the parts are in position for a fresh starting operation.
