Title: Fuel injection apparatus
IPC: F02M41/12
Filed: 1972-11-24
Abstract: 1411624 Fuel injection pumps ROBERT BOSCH GmbH 24 Nov 1972 [26 Nov 1971] 54296/72 Heading F1A A fuel injection pump includes a centrifugal governor having a speed sensitive adjusting member 47 axially movable to control the movement of termination of injection and also the output pressure of a feed pump 24 controlling the timing of the commencement of injection. The pump is of the kind comprising a piston 8 reciprocable and rotatable in a cylinder 17 by a shaft 2 coupled to the piston, the latter having an end face cam 3 urged by spring 14 to co-operate with rollers (not shown) on a ring 6. A piston (67) loaded by a spring (70) and responsive, via a channel 69, to the feed pump pressure delivered to a chamber 26 causes rotation of the ring 6 and thus controls the commencement of injection. As the speed increases the pressure in the chamber 26 increases, but raising of the adjusting member 47 by the governor flyweights 52 provides a variable bleed off to the suction side 65 of the feed pump via passages 60-64. Raising of the member 47 occurs against the action of springs 54, 55 thereby to pivot a lever 42, 43 and move a sleeve valve 41 controlling a spill passage 38, 39 and thus the termination of delivery. The tension of the spring 57 is adjustable by displacement of an externally operated lever 58 thereby to determine the speed to be regulated. The lever 42, 43 is pivoted on a pin eccentrically mounted on an adjustable shaft 45. Fuel is admitted to the pumping chamber 30 through channels 27, 28 and whichever of piston grooves 29 is in alignment with the channel 28. Delivery from the pumping chamber passes through a delivery valve 21 and passages 31 to an annular groove 33 where it is distributed in turn to outlets 35, 36 by a groove 34.

Title: Electronic Time Base Generator
IPC: H03K5/14
Filed: 1967-12-07
Abstract: 1,156,590. Time base generator. INTERNATIONAL STANDARD ELECTRIC CORP. 7 Dec., 1967 [13 Dec., 1966], No. 55751/67. Heading G4A. An electrical time base generator comprises a delay line with a plurality of taps to which are connected threshold detectors for opening and closing gating means, one of which means is provided for each impulse to be generated. As shown (Fig. 1), a delay line LR comprising inductances sf and capacitors cd has a number of taps pr to which differential amplifiers AD may be selectively connected. Each differential amplifier is such as to conduct when its side input terminal is negative with respect to its other input terminal. Thus, when the leading edge of the pulse travelling down the line LR reaches the tap connected to AD3, AND-gate pt5 is opened to initiate the impulse td. The gate pt5 is closed to terminate the impulse td when the leading edge of the travelling pulse reaches the tap connected to AD4. The cycle of operations is started by a pulse sd applied to gate pt2. The first two differential amplifiers AD1 and AD2 and gates pt1 and pt2 are concerned with accurately timing the length of the travelling pulse and with providing impulses to and th for setting control bi-stable devices aa and ab respectively. A further AND-gate pt3 at the input to the delay line enables the travelling pulse to be regenerated for a second cycle to be performed. Impulses of relatively long duration may be produced by using impulses generated using the delay line to set and reset bi-stable devices such as tl1 and ti1. Impulses may be generated selectively in either the first cycle only, the second cycle only or both.

Title: Liquid fuel injection pumping apparatus
Inventor: KNIGHT BASIL EDWARD
IPC: F02M41/16
Filed: 1967-12-08
Abstract: 1,244,727. Fuel injection pumps. C.A.V. Ltd. Dec.2, 1968 [Dec.8, 1967], No.55857/67. Heading F1A. [Also in Division G3] A liquid fuel injection pumping apparatus comprises an injection pump 1 which is operated by a cam rotatable by a shaft 70 supplying fuel through an accumulator 3, a rotatable distributer member 44 which has a delivery passage 12 which registers in turn and as the distributer rotates with four outlet ports 14, and four feed passages 76 which register with a feed port 10. There are also provided four relief passages 13 registering in turn with a relief port 15. A predetermined quantity of fuel is delivered by the pump 1 to the accumulator 3 and the pressure causes the valve member 4 to be raised to establish communication between ports 5, 8 and fuel flows to an outlet port 14 via the delivery passage 12 and a feed passage 76. Injection of fuel continues until the pressure within the accumulator 3 has fallen and the valve member 4 lowers to close port 8 and place the outlet port 14 in communication with the constant pressure valve 17 via relief passages 13, port 15 and the groove formed between lauds D, E. The quantity of fuel delivered is hence dependant upon the effective stroke of the pump 1. The outer ends of the feed passages 76 are formed as helically disposed grooves 11 of varying depth as shown in Fig. 2 and which in conjunction with port 10 forms a variable orifice to apply a differential pressure to a pressure control valve 47 to control the initial rate of injection of fuel. Movement of the rack bar 19 effects angular adjustment of the plunger 1, and hence varies the quantity of fuel injected, and imparts axial movement to the shaft 25. Valve member 28 is slidable axially relative to the shaft 25 and is biased by a coil spring against the action of centrifugally operable weights 26. Liquid pressure supplied by a constant pressure source 35 is applied via pipe 45 to one end of the distributer member to alter its axial setting and hence the timing. This pressure is made speed dependant as a result of the action of the governor weights on the valve member 28. Pressure is also applied to the other end of the distributer which is load dependant. The pressure in the pipe 45 also controls a piston 21 which modifies the maximum delivery of fuel by the pump 1.

Abstract: 1,222,265. Cathode-ray tube displays. INTERNATIONAL STANDARD ELECTRIC CORP. 27 Nov., 1968 [6 Dec., 1967], No. 56286/68. Heading H4T. In an arrangement for displaying data received from a computer on one or more display devices (e.g. cathode-ray display tubes) the data is first stored in a buffer memory from which it is transferred to a further memory device(s) each associated with a respective display device, each of the further memory device(s) storing a complete row of data which may be recirculated therein via the buffer memory a plurality of times to enable a single row of data (e.g. symbols, characters &c.) to be reproduced on the display device(s) during a like plurality of line scans. Fig. 1 shows the general scheme in which the computer 1 is connected over a link 2 to an adapter 3 and thence to driving means 4 comprising a computer communication device 6 (enabling data produced by a keyboard 11 to be fed to the computer), an image memory 7, a symbol generator 8 and via a control unit 9 to one or more display cathode-ray tubes 5. Referring to Fig. 2, the image memory 7, comprising a magnetic-strictive delay line, is connected with a shift register 14 to form a recirculating delay line memory from which, under the control of clock pulses the data appertaining to a complete row of symbols, characters &c. is transferred to a row memory 15 in which it is recirculated the plurality of times which the line scanning of the display tube(s) requires for reproduction (in the form of bright-up points on a line raster). At each recirculation the data is transferred to a decoder 17 and thence to a diode matrix 18 which provides signals controlling the production of the actual signals required to produce the symbols &c. by brightness control of the beam of the display tube(s) in the form of a 5 x 7 dot matrix. Such signals may be utilized directly if a monitor type display tube unit is employed but if a conventional television receiver is employed the signals are first modulated at 20 on to a suitable carrier wave frequency. It is assumed that eight interlaced lines are necessary to reproduce one row of symbols &c. and the plurality of times that the data is recirculated in memory 15 is therefore eight. A further arrangement is described (Fig. 3, not shown) in which memory 15 comprises seven shift registers fed in parallel from shift register 14 and connected in sequence to the decoder each register being up-dated when its contents have been transferred so that data appertaining to eight rows is always in transit.
