Abstract: 1526168 Grouping cigarettes together on a conveyer IMASCO Ltd 10 June 1977 [26 Oct 1976] 24396/77 Heading B8A Cigarettes in a stream on a conveyer 2 are counted until a predetermined number have passed a separator plate 6. The latter then drops and halts the flow, whilst the counted cigarettes travel towards a downstream catcherplate 10. An upstream catcher plate 7 then drops and moves towards the plate 10, the counted cigarettes thus being gathered between the two catcher plates. Carriages 8 and 11 respectively carrying the catcher plates 7 and 10, then latch together and move downstream to a position above an elevator platform 15. This lifts a container which has been delivered by a conveyer 14. The catcher plates 7 and 10 then release the cigarettes which drop into the container. The filled container is removed laterally on a conveyer (20) (Fig. 1, not shown). The cigarettes are additionally retained between the catcher plates by the action of silk ribbons 21 and (24) loaded by a weight 23.

Patent GB-799286-A (GB)
Title: Improvements relating to the operation of gas turbine aircraft engines
IPC: F02C9/16
Filed: 1956-08-16
Abstract: 799,286. Gas turbine plant. GENERAL MOTORS CORPORATION. Aug. 16, 1956 [Aug. 16, 1955], No. 25040/56. Class 110 (3). The fuel supply to a turbopropeller aircraft engine is regulated by a fuel metering valve actuated by apparatus responsive to ambient conditions, engine rotational speed and throttle settings to maintain a turbine inlet temperature set at each throttle setting above a given setting higher than that required for an idling speed which is suitable for landing approaches and to maintain engine power output substantially constant at the idling speed setting. Fuel is supplied to the engine through a metering valve the pressure drop across which is maintained constant by a by-pass valve which returns excess fuel to the inlet of an enginedriven fuel pump. The metering valve comprises a sleeve 73 having a rectangular opening 72 which co-operates with a rectangular opening 71 in a valve member 70 mounted on a shaft 32. The area of the flow orifice may be varied by axial or rotary movement of the valve member 70. The rotary movement is controlled by a servomotor 78 responsive to the total pressure in the gas turbine compressor air intake through a rack and pinion. The axial movement is normally controlled by a cam 50 acting through a cam follower 61, a collar 62 splined to a sleeve 59, arms 58, 57, a sleeve 54 and an arm 66 which bears against a disc 67 on the shaft 32. The cam 50 moves the valve member against the action of a spring 33 the loading of which is determined by the setting of the throttle acting through a lever 34. A centrifugal speed governor acts on the plate 31. This speed governor acts as an emergency governor in the event of failure of the propeller governor and limits or controls engine shaft speed under taxying or fixed propeller pitch conditions. The cam 50 is mounted on a shaft 43 which is axially movable against the action of a spring 44 by bellows 42 connected through a capillary tube 41 to temperature sensitive means in the compressor air intake. The shaft 43 is rotated in accordance with engine speed by a servomotor 47 controlled by a shaft 36 forming part of a second centrifugal speed governor. The shaft 43 also carries an acceleration limit cam 52 which may override the cam 50 during transient conditions due to changes of throttle lever settings by separating the arms 57, 58. In normal flight, the follower 61 is at the lefthand end of the cam 50 and the combined effects of inlet pressure and temperature and engine speed acts to maintain the turbine inlet temperature set by the throttle. If the throttle is now moved back, the sleeve 62 is moved by the lever 30 towards the right and the cam 50 then calls for less fuel input. The cam 50 at this position is designed to maintain constant power instead of constant turbine inlet temperature with variations of compressor inlet temperature. At this position, the cam 50 is also contoured so that the fuel flow is increased with decreasing engine speed. The governor 35 therefore acts as an underspeed governor.
