[Also in Divisions G2-G3]  A film or tape feeding device for extracting the free end of a strip 104 coiled on a reel core 103, e.g. from its cartridge 101, comprises a belt-driven friction roller 109 mounted on a member 108 displaceable to press only the arcuate portion of the belt 115 backed by roller 109 against the outer convolution of the coil, the endless belt passing over second and third rollers 116, 136 such that the belt approaches the nip between roller 109 and the coil at an obtuse angle to free end of the strip. Member 108 carries motor 117 to drive roller 116 and is spring urged towards cartridge 101 to insert roller 109 in aperture 107 when the cartridge engages apparatus 125. A plate 120 on member 108 deflects spring 122 to form a guide directing the film end round the coil clockwise along cylindrical wall 110 to leave through aperture 106, via stripper 124 engaging the coil. Fast rewind is provided by belt 127 on roller 126 driven by a separate motor 128 independent of member 108. Roller 126 engages friction wheel 112 with a pin 113 on which reel 102 fits. In the embodiment of Fig. 4 (not shown), a separate motor 117 is not included, the belt passing over three shiftable idle rollers, including the friction driving roller (9), and a fixed driven roller (14). The free end of the strip is led through a constant width channel defined by the belt portion (13a) and the stripper (15), the stripper being guided by pins (24, 25) in cam slats (16, 17) as the spool diameter changes. Different sized spools can therefore be used.

The liquid may be milk, juice or other beverage, or liquid medicine. The term "liquid" also includes any non-gaseous material that will flow. The movement may be effected by rocking, rolling, rotating or shaking the vessel. Apparatus is described for effecting these. various movements. In Fig. 1, ampoules of liquid 13 are positioned in holder 12 in micro-wave oven 2. The holder 12 is mounted on movable support 7 which is subjected to a rocking motion by the motor driven cam 11 co-operating with drive rod 8. The ampoules may alternatively be subjected to a rolling motion in an apparatus of the type shown in Fig. 2A wherein ampoules 13 are carried through a micro-wave oven by belt conveyor 16. The ampoules are rotated whilst on the moving belt conveyor by contact with a keep plate 17. The belt conveyor has pawls 18 formed on its upper surface (Fig. 2B, not shown) which engage the ampoules to facilitate their rotation. A rolling movement may also be imparted to the ampoules by allowing ampoules to roll under gravity down inclined chutes which are positioned in a micro-wave oven (Fig. 3A, not shown).

Abstract: 1296065 Counters WESTINGHOUSE ELECTRIC CORP 19 Feb 1970 [19 Feb 1969] 8010/70 Heading G4A The output from a predetermined counter is dependent on occurrence of a signal resetting the counter. A binary counter 12 receives a train of 31 pulses A followed by a space A<SP>1</SP>. A reset pulse B is coincident with space A<SP>1</SP> and resets all stages FF1-FF5. The predetermined count is set up by connecting appropriate Q and Q terminals to corresponding condition sensing circuits 22a-22e. When the predetermined count is attained, a burst of high frequency pulses from a generator 36 passes through 22a- 22e and is applied to a gate 26s. The resetting pulse B is applied to a sensing circuit 22m and after the counter has reset the Q terminals of all stages enables circuits 22n-22r so that another burst of pulses from 36 passes through 22m-22r to a detector 44 and an R-C circuit 42 which stretches the reset pulse effectively to cover the whole of the subsequent counter cycle. This pulse opens gate 26s to the predetermined count signal to produce an output at 46. Failure at any point stops the output. The system is applicable to fail-safe systems such as railways and multiplexing systems where each receiver station is allotted a different time slot.

Thus the output of the differential amplifier 40 is a pulse lasting for the duration of an input pulse between half height levels, and this is used to gate clock pulses passing from an oscillator 44 to a counter 45.
