Title: Signal-controlled system for ejecting liquid drops from a nozzle
IPC: H04N1/034
Filed: 1974-02-06
Abstract: 1448293 Ink jet production GOULD Inc 6 Feb 1974 [7 Feb 1973] 05439/74 Heading B6P Ink jet producing system comprises an electro-acoustic transducer 17 acting on conduit 5 to produce pressure waves in ink 2 which result in drops 13 being formed at nozzle 11. Pressure waves travelling back towards the reservoir 1 are absorbed by means such as a viscoelastic conduit 4 which ensures that no reflected waves pass back to the nozzle 11 and cause undesired drop formation. As shown the transducer 17 is cylindrical with a lead zirconate-lead titanate ceramic tube 20 having electrodes 22, 23 and is radially polarized. The dimensions of the conduit 4 may be determined experimentally by using a second similar but shorter transducer 32 which senses the pressure waves created by the transducer 17 over a range of frequencies applied to it. This produces a graph of the transducer's 32 output against frequency for different conduit constructions, the more even response being preferred.

Title: Unloading and flow dividing valve
IPC: B62D5/07
Filed: 1974-02-12
Abstract: 1403483 Power-steering mechanism AISIN SEIKI KK 12 Feb 1974 [13 Feb 1973] 6306/74 Heading B7H [Also in Division F2] In a flow-dividing valve for a vehicle steering and braking system when a pump P is operated a spool valve 13, having a restricted orifice 29 leading to an annular groove 30, moves to the right as a result of the pressure difference across the valve arising from the pressure drop through the orifice. This movement of the valve opens communication between the pump and an outlet leading to the power steering unit P/S. Flow through the orifice leads, via a transverse and an axial passage in a piston member 14, towards a spring loaded valve 19 which opens to admit fluid to an outlet leading to the braking system P/B and an accumulator ACC. When the accumulator is fully charged a spring loaded ball valve 21, which leads to a reservoir Re opens partially. The valve 19 then moves back on to its seat on the end of the piston 14 and the piston moves bodily to the right to open the valve 21 fully with a snap action. Fluid from the pump is now unloaded to reservoir, flowing via the orifice 29 into a chamber 31 divided into two subchambers 43, 44 by an annular member 42 held in place by a spring 34. The outlet from the sub-chamber 43 is via an annular groove 45 and an axial passage 46. However, the righthand end of the spool valve 13 will have moved to the right to restrict flow to the groove 45. This prevents the drop in pressure which occurs in the sub-chamber 44, on opening of the valve 21, from being transmitted to the sub-chamber 43 and thence to the steering circuit where it would otherwise be felt as a slight shock. In another embodiment, Fig. 1 (not shown), the annular member 42 is omitted and the axial passage in the piston is extended further to the right where an additional transverse passage (17) provides the flow path to the chamber 31, which, in the absence of the annular member 42 is in direct communication with the valve 21 and not via the orifice formed between the spool valve and the groove 45. Pressure drop when the valve 21 opens is thus transmitted into the steering circuit, producing a slight shock.
