Abstract: 1,048,654. Cigarette-making machines. K. KÍRBER. Jan. 7, 1963 [Dec. 15, 1961], No. 44991/61. -Heading A2C. A method of checking for faulty wrappers of cigarettes comprises introducing compressed air into both ends of the cigarettes and measuring pressure in the cigarette, escape of air in the case of faulty cigarettes causing a drop in pressure sufficient to actuate mechanism for rejecting the cigarette. A drum 1 is provided with central grooves 2 and lateral clamp blocks 3 and 4 which are controlled to move backwards and forwards in an axial direction by rollers 5 and 6 which co-operate with came 48 and 49. The ends of the cigarette groups G are supported in sealing caps 7 and 8, having openings 11, fastened to the blocks 3 and 4. Compressed air is fed from a pipe 80 via a line 75 to lines 74 and 76. Lines 74 and 76 register with bores 30 and 26 in blocks 3 and 4 and the bores 30 and 26 communicate with bores 11 in the caps 7 and 8 and with bores 32 and 25 which lead through blocks 14 to a diaphragm 20. The diaphragm bears against a pivoted lever 36 which is urged against the diaphragm by a spring 46. The cams 48 and 49 cause the group G to be gripped by the caps 7 and 8 and compressed air is then fed to the ends of the group and to the diaphragm 20. If the group is properly wrapped the pressure in the diaphragm is sufficient to lift lever 36 against the action of spring 46 so that a latch 39 on the lever engages a projection 40 on the block 4 and the group is held on the drum 1 after the cam 49 falls away from roller 6 at the rejection station B. If the group is faulty the pressure in the diaphragm is insufficient to overcome the spring 46 and the block 4 is not latched. Block 4 then moves outwardly under the action of spring 18 when cam 49 falls away from roller 6 at the station B, thus releasing the faulty group.

Abstract: 1,110,159. Counting apparatus. VEEDER INDUSTRIES Inc. 11 Oct., 1966 [22 Oct., 1965], No. 45419/66. Heading G4D. In a liquid-fuel dispensing apparatus the volume and cost counters are maintained undisturbed after one dispensing operation until they are reset accurately immediately before the next dispensing operation begins. Before the nozzle can be taken from its holder coupling 38, control shaft 36, and control plate 40 must be turned counter-clockwise in Fig. 3, so turning reset drive plate 42 through 60 degrees to load spring 50 and engage drive pawl 46 with the next notch in disc 44. Rotation of control shaft 36, clockwise as seen in Fig. 1, also rotates cam 100, which initially holds slide 20 in right-most position so that the counter shafts 10-13 are maintained in normal operating positions. As the dispensing mechanism is still disabled the counters maintain their previous readings. Manual operation of shaft 79, clockwise in Fig. 3, and counterclockwise in Fig. 1, pivots trip pawl 80 to release reset drive plate 42 which returns under spring action. Simultaneously pin 116, Fig. 1, swings cam 102 clockwise and permits cam 100 to turn further clockwise, whereby slide 20 is driven to the left to displace the counter shafts 10-13 axially for resetting. Cam 102 is held by latch 121 until control plate 40 is turned in the opposite direction when cam 100 releases latch 121 and returns slide 20 to the right. The counters are again in operative position and the dispensing mechanism is enabled.

Abstract: 1441262 Regulating IC engine fuel injection CAV Ltd 24 Sept 1973 [4 Oct 1972] 45722/72 Heading F1B The timing of the fuel injection angle for an I.C. engine cylinder is controlled by the engine load, represented by the quantity of fuel supplied to the engine, and the engine speed in a retroactive servo loop. The load signal determined at 22 Fig. 2, limited to a maximum value at 33, is combined at 35 with the speed signal determined at 21, limited to a minimium value at 34. A top dead centre signal at 24 switches on a timer 36 which is switched off by an injection signal at 23, the clockpulse count from timer 36 being multiplied by the speed signal from 21 and converted to an analogue angle signal at 38. The difference between the signals at 35, 38, representing the timing error is determined at 39 and added algebraically at 42 to the main command signal at 35, the resultant control signal being fed to a torque motor 32 to adjust the injection timing. When the fuel supply is cut-off and no injection signal is obtained at 23, a unit 43 reduces the resultant control signal to zero. The fuel pump comprises a rotary member 10 Fig. 1 driven by the engine, with a transverse bore 11 containing opposite plungers 12 operated by lobes 15 on a cam ring 16. The angular positions of the lobes are adjusted by an hydraulic device 17 controlled by the torque motor 32 as above. The quantity of fuel supplied to the pumping chamber 11 is determined by means not described.
