Title: Digital electronic watch
IPC: G04C3/10
Filed: 1974-10-29
Abstract: 1482176 Electronic watches HUGHES AIRCRAFT CO 29 Oct 1974 [29 Oct 1973] 46785/74 Heading G3T [Also in Division G5] An electronic digital watch, Fig. 1, is provided with a liquid crystal display 40 which continuously displays hours and minutes in normal operation of the watch and with an L.E.D. display 41 which will display only on demand the hours and minutes e.g. when ambient light conditions are unsuitable for viewing the liquid crystal display. With push-switches 50, 52, Figs. 1 and 2, not depressed, hours and minutes are continuously displayed by the liquid crystal display 40. When switch 50 only is depressed seconds and tens of seconds only are displayed on devices 26, 28. When switch 52 only is depressed the date only is displayed on devices 26, 28. When both switches 50, 52 are depressed the time in hours and minutes will be displayed by the LED display 41. Additional counters may be provided to permit display of the month.  In Fig. 2 a crystal controlled oscillator 60 followed by a CMOS frequency divider 62 produce timing pulses at 1Hz to drive CMOS counters 64, 66, 68, 70, 72, 74, 76, 78. The counters outputs are respectively coupled via transmission gates 92, 94, 96, 98, 100, 102, 104 to multi-plex inputs 84, 86, 88, 90 of a decoder 82. Each input, e.g. input 84, consists of four lines to carry BCD information from the counters when the respective transmission gates are opened by clock pulses from a multi-plex driver 106 via a line 105. The driver 106 also delivers digit select signals to a demulti-plexer unit 110 via a line 107. The decoder output is demultiplexed by the unit 110 which produces 7-segment outputs to each liquid crystal display device 24, 26, 28 via a respective memory driver 112, 114, 116 which continuously activate selected segments. Even when a gate blocks information from a counter, the memory driver will maintain displayed the previous information received thereby. An output 109 from multi-plex driver 106 determines which LED display device will receive information from decoder 82 when switches 50, 52 are both depressed. The watch may be arranged to display also the seconds and date on the LED display.

Abstract: 1438338 Rotary internal combustion engine L S SAUNDERS G P ZEPERNICK R H WATTS and M A ALBERT 8 Oct 1973 [11 Oct 1972] 46882/73 Heading F1F A two-stage rotary internal combustion engine comprises housing cavities 7, 8 with three-lobed rotors 1, 2 therein, the rotors being rigidly mounted on a common shaft 3 such that the trailing faces of the lobes 26 of rotor 1 and the leading faces of the lobes 27 the exhaust rotor 2 overlap, a gap being left between the other ends of the lobes, inlet ports 42 leading into the inlet chamber 7, outlet ports 45 leading from exhaust cavity 8, transfer ports 43 between the cavities 7, 8, and radially slidable vanes 28, 29 in the cavities 7, 8. Fuel/air mixture is inducted into the space between lobes 26 and 26' after the trailing face of lobe 26 has passed vane 28. When the trailing face of lobe 26 passes the next vane 28", then the mixture is compressed between the leading face of the next lobe 26' and vane 28". Just prior to the passing of the leading face of lobe 26 past vane 28", the gap between this face and the trailing face of lobe 27' of the other rotor coincides with transfer port 43" and ignition of the mixture by means 40 in the inlet cavity 7 causes the mixture to be thrust through port 43 and  expand in the space between lobes 27' and 27" to drive rotor 2, the gases being finally exhausted through port 45'. Clearly, all three inter-lobe spaces undergo three power strokes for each revolution of the rotor.

Abstract: 1,094,127. De-panning apparatus. S. E. MATTHEWS (J. B. Schmidt, A. S. Schmidt, Jun., H. A. Maurer, N. S. Murphy and B. S. Herrick [trading as ALTO CO.]). Nov. 23, 1964, No. 47549/64. Heading A2A. [Also in Division B8] Apparatus for de-panning and conveying baked products, such as loaves of bread, rolls or buns, comprises a travelling conveyer belt 15 having an upwardly inclined first flight 17, along which pans filled with baked products are conveyed, and a downwardly inclined second flight 18, along which empty pans are conveyed to a discharging conveyer 46. Magnetic devices 24 may be provided under the flights 17 and 18 to hold the pans thereon. Each of the flights 17 and 18 may be inclined at 12 degrees to the horizontal. The flights 17 and 18 meet to form an apex 22, where the filled pans are tilted below the suction flight 28 of an endless travelling belt 25 pierced by openings 26. The suction thus applied to the baked products removes them abruptly from the pans to the underside of the flight 28, where they are held by the suction and carried to a point where suction is not applied, and there deposited on to a discharging conveyer 43. Jets of compressed air issuing from nozzles 47 may be directed downwardly on to the baked products approaching the apex 22, so as to loosen the products from the pans and help the products to move towards the flight 28. In an alternative construction of the apparatus, Figs. 6 and 7 (not shown), the first and second flights are provided by two separate, pivotally mounted, endless conveyer belts, which can be adjusted on their mountings, as by jacks, to vary the inclinatoins of said flights, e.g. to bring them into horizontal alignment.

Each recess 5 is provided with a pair of dies 6, 7, which may be slid towards and away from each other by cam tracks 9, 10 respectively. The cam tracks 9 are arranged to act on the outer ends of the dies 6, 7 so that each lump'15 is first pushed by the associated die 7 into the guide 8 of the die 6 which is stationary and is then moulded by movement of the die 6 towards the die 7, the die 6 being temporarily partially retracted whilst a lollipop stick 19 is inserted into the lollipop. The sticks 19 are fed one at a time froma funnel 18 into radial channels 20 of a plate 21 attached to the drum 1. Each stick 19 is driven from its channel 20 through a passage 30 in the guide 8 of the die 6 into a lollipop by a finger 24 of a respective cam actuated, spring-loaded pin 25. A cover-plate 22 prevents loss of the sticks 19 from the channels 20. Wheels 11 are provided on the guides 8 to facilitate retraction thereof by the cams 10. The pressing faces of the dies 6, 7 may be concave or planar.
