Abstract: 1,266,803. Fuel injection systems. SOC. INDUSTRIELLE DE BREVETS ET D'ETUDES. Feb.6, 1970 [Feb. 14, 1969; April 28, 1969], No.5701/70. Heading G1N. [Also in Division F1] In an I.C. engine fuel injection control system, the quantity of fuel injected is determined by the position of an auxilliarly throttle member 8 positioned in the air intake manifold 1 upstream of the main throttle member 2. A rotary member 5, which may be driven at a constant speed or by the engine, provides a release signal, e.g. by a magnet 24 and sensor 23, for a predetermined constant fraction of rotation, this release signal then causing a generator 6 to provide a signal for energizing the electromagnet(s) 4 of the injection valve(s) 3. As shown, during the release signal a capacitor 19 is charged through a switch 21 by a battery 22, and at the end of the release signal the capacitor is discharged through a resistor varied by the auxilliarly throttle position and a threshold circuit 46 thus energizing the electromagnet 4 as long as the discharge current exceeds the threshold. In another embodiment, Figs. 3-5 (not shown), the release signal energizes a flip-flop (57) to provide an output signal whose duration is determined by comparing the signal on the wiper of a potentiometer positioned by the auxilliary throttle member with the feedback signal of a modulating member (50) actuated by the flip-flop (57). The output signal is then compared in an AND gate (65) with a signal whose duration is representative of that required to provide fuel during idling, thus providing a fuel inhibition facility. In a further embodiment, Figs. 6 and 7 (not shown), the release signal is applied to one input of a flip-flop (103) whose other input is connected to the output of a read-out device (91) and decoding member (93). The read-out device is supplied with the number of counts stored in a read-in device (90) during a previous release signal this number of counts being determined by the position of the auxilliary throttle. The number of counts in (91) is then reduced to zero at a constant frequency, an output signal being provided by the flip-flop 103 during this time. The output pulse may again be compared with the idling value pulse. The energizing pulse duration may be increased during starting and the fuel pressure may be adapted to the pressure between the two throttle members 2, 8 to adapt the fuel-flow to conditions of acceleration.

Abstract: 1297879 Semi-conductor image sensors NORTH AMERICAN PHILIPS CORP 2 July 1971 [6 July 1970] 31101/71 Heading HIK [Also in Division H4] The individual storage elements of light detector array (i.e. an image sensor) which are sampled by a cross-conductor addressing system, each comprise a phototransistor 10 with its emitter region 12 capacitively couple@ 20 and 18 to a row and to a column conductor, the collector region of all the phototransistors in the array being commoned and connected to an output circuit comprising a load resistor 26 and a voltage source 28, an output being derived therefrom via a capacitor 30. The base region of each transistor shields the collector region from the conductors of the addressing system, and is coupled to a source of reference potential, e.g. ground. The phototransistors are sampled - sequentially when pulses from row and column scanning pulse distributers 24 and 22 coincide for a particular phototransistor, the output signal being proportional to the amount of light incident on the phototransistor since it was last sampled, i.e. one frame period integration time. A description of the operation of each phototransistor is given with reference to Fig. 3 (not shown), it being stated that the electrostatic shielding provided by the ground base region between the addressing conductors and the output circuit lead reduces the effect upon the output signal due to capacitive couplings therebetween. One element of the array which is constructed in integrated form is shown in Fig. 4, the capacitors 16 and 20 being integrated along with the phototransistor. As shown, P-type emitter regions 64 are diffused into an N-type substrate 62 (which forms the transistors base region) through holes in a silicon dioxide insulating layer 66, and at the same time a common P-type collector region 68 is formed on the opposite side of the substrate. A thin silicon dioxide layer 69 is then provided over each of the P-type emitter regions 64, and electrodes 70 contacting this thin layer 69 are connected to the row and column conductors 72 and 74, i.e. layer 69 forms capacitors 18 and 20. Conductors 72 and 74 may be incorporated into the integrated circuit. Additional grounded points for base region 62 may be provided by etching through the surface oxide layer 66.

Locating means (16), (Figs. 1, 13, not shown), are provided for the dispensing units enabling them to be readily laterally repositioned to accommodate different article sizes. Coin-action.-Inserted coins are received in a pocket 58 in a coin-counting block (57) that is removably positioned in the element 66 (Figs. 8 to 10, not shown). A plate (59) may be inserted in the pocket to restrict the number of coins required. On initial rotation of the shaft 74 the coins act on dogs 61 to lift them above stops 64 and permit further rotation of the shaft. Dispensing mechanism.-In one embodiment each dispenser unit comprises an arm 76 loosely mounted on shaft 74 and operatively coupled thereto by means of pins 80 riding in cut-out segments in sleeves 78. Each arm carries a pull knob 41 and spindle 52, non- return pawl and ratchet means 82 and a counterweighted pivoted paddle 92. After insertion of the appropriate coinage the knob 41 is first pulled until the paddle 92 engages the front of a packet and then pushed to deliver the packet into a delivery shoot. In another embodiment (Figs. 14 to 16, not shown), the coin-receiving element (66a) is fixedly mounted on a square shaft. Preventing actuation of more than one dispensing unit.-In the first embodiment each arm 76 has a knife-edge 88 that on pulling of the delivery knob 41 enters between locking bars 90 moving them laterally and hence preventing actuation of other units. In the second embodiment knife-edges (88a) are arranged to enter the gap between locking blocks (112) slidably carried in a guide rail (114). Preventing actuation when machine empty.-A weight (44) rests on the top of each pile of articles and when sold out the weight depresses a lever (47) into engagement with a notch 50 in spindle 52 (Fig. 4, not shown) or alternatively (Fig. 13, not shown) presses the lower end (108) of a spring-loaded bar (102) into engagement with the notch 50. Coin-return.-A sliding block (69) attached to a spindle 68 is provided to return coins by pushing them out of the pocket 58 when the spindle 68 is pulled (Figs. 5 to 7, not shown). The block (69) and element (66) co-operate to prevent coin return if a dispenser unit is actuated.
