Title: Fuel injection nozzles
IPC: F02M45/12
Filed: 1969-07-07
Abstract: 1314017 Fuel injectors CAV Ltd 26 June 1970 [7 July 1969] 34132/69 Heading F1B In a fuel injection nozzle of the kind in which fuel pressure unseats a valve member 15, Fig. 1, to commence fuel injection through an orifice 11 a mechanical connection between the valve member and resilient means 18 loading it is divided to define a variable volume chamber to which fuel is supplied from an inlet, the maximum volume of the chamber being limited and so arranged that fuel flowing though the inlet initially flows at a restricted rate to the orifice and when the chamber has attained its maximum volume the valve member is lifted to allow substantially unrestricted flow through the orifice. Fuel supplied from pump 8 to groove 25 passes via restrictor 24, passage 23 and grooves 22, 21 to the chamber between piston 16 and valve member 15 and also passes to gallery 13, to unseat valve member 15. Fuel continues to flow into the chamber moving piston 16 until groove 22 is closed to port 23 whereafter piston 16 and valve member 15 move together so that fuel can flow through orifices 11 at an unrestricted rate. When the fuel-flow ceases the fuel in the chamber escapes via grooves 21, 22, port 26 and non- return valve 27. The restriction imposed by restrictor 24 can be made variable in accordance with speed. In another embodiment fuel is supplied through a restrictor 24, Fig. 2 to a chamber between piston 16 and valve member 15 and supplied directly to gallery 13. Initially piston 16 rises and valve member 15 and distance member 28 then rise to allow a restricted fuel-flow. During lifting fuel flows into the chamber beneath distance member 28 and piston 16 eventually opens port 31 to allow fuel pressure to act on piston 33. The latter rises to cut off the incoming fuel-flow and thereafter the valve member 15 rises under the action of fuel pressure in gallery 13 to allow unrestricted fuel-flow through the orifices 11. Piston 33 has a restricted through opening to allow its return during non-injection periods. In another embodiment a valve member (50) Fig. 3 (not shown) is initially lifted to allow fuelflow at a restricted rate. Meanwhile fuel at a higher pressure lifts a piston (52) having a groove (55) which eventually registers with a bore to permit a full pressure flow to gallery (13) causing unseating of the valve member (50) and fuelflow at an unrestricted rate. The gallery (13) is fed through a restrictor 51. The restriction imposed can be modified to obtain different delivery curves.

Title: Apparatus for detecting faults in insulated electric conductors
IPC: G01R31/02
Filed: 1969-05-29
Abstract: 1317154 Testing cable insulation BRITISH INSULATED CALLENDER'S CABLES Ltd 29 May 1970 [29 May 1969] 27217/69 Heading G1U A cable 1, Fig. 2, whose insulation is to be tested is drawn through two h. v. electrodes 14, 14' so that as a void in the insulation passes the pair of electrodes two successive discharge signals are produced, and a circuit 28 is provided which distinguished genuine discharge signals from background interference by providing an output only when two successive signals are received which are spaced apart in time by an interval corresponding to the time taken for a portion of the cable to travel from one electrode to the next. The cable 1 is drawn through an insulating tube 11 which has earth electrodes 16 at each end and the two h.v. electrodes 14, 14' in the middle, and through which de-ionized water flows in the opposite direction to the cable movement. The two h.v. electrodes 14, 14' are connected to a high voltage source 25 and form parts of a bridge detecting circuit having an output transformer 24. A calibration signal source 37 is connected to one electrode. The signal from transformer 24 is passed via a detector 27 to the circuit, 28, shown in Fig. 3. Here discharge recognition unit 31 provides an output pulse when the signal received from detector 27 is above a minimum amplitude. Such pulses are passed directly to one input of an AND gate 40 and also via a channel 56-58 to a second input, this channel providing a transient pulse shortly after the onset of each pulse received from unit 31. Pulses from unit 31 also trigger bistables 43, 49 which supply signals to two further inputs of AND gate 40 and which together define an interval during which a further pulse must be received from unit 31 if the two pulses are to be recognized as genuine discharge signals. The duration of the pulses provided by bistables 43, 49 is controlled by counters 46, 53 which in turn are controlled by a clock pulse generator 33. The later is regulated by a measuring wheel 34, Fig. 2, driven by the cable 1 under test so that the clock pulse frequency is proportional to the cable speed. Thus when a pair of signals are received by unit 31 having the required minimum amplitude and the appropriate spacing, a pulse is produced at the output of gate 40. This pulse may, after a further delay controlled by counter 62, operate a paint spray 35 for marking the cable and recorder 36.
