Title: Improvements relating to liquid fuel injection systems for internal combustion engines
Inventor: NICOLLS WILFRID EDWARD WALTER
IPC: F02D1/00
Filed: 1948-08-28
Abstract: 643,246. Regulating. C.A.V., Ltd. Aug. 28, 1948. No. 22742. [Class 7(vi)] A temporary increase in the fuel supply on opening of a throttle valve t is effected by a diapragm d which temporarily closes a switch o, and thus energizes an electromagnet r which moves the control rod of a fuel injection pump q. The diaphragm d has a hole g closed by a lightly spring- loaded valve h which has a small orifice k. During normal running the pressures in the chambers b and e are equal and the switch o is open. On acceleration, the rise in pressure in the induction pipe f is transmitted to chamber b by a pipe e and the diaphragm d is raised to close the switch o. The pressures in chambers b, c, slowly equalize through the orifice k, which returns the diaphragm d to its equilibrium position and opens the switch o to allow the pump control rod to return to its normal running position. When the valve t is closed, the increased suction in the chamber b opens the valve h to equalize the pressures in the chambers b, c, immediately, leaving the diaphragm unaffected.

Filed: 1954-08-09
Abstract: 764,096. Protective arrangements. TELEFONAKTIEBOLAGET L. M. ERICSSON. Aug. 9, 1954 [Aug. 7, 1953], No. 23143/54. Class 38(5) In an arrangement for indicating abnormal operation of one or more devices within groups of supervised devices, each device is arranged to apply a D.C. biasing voltage U11...U14, U21...U24 to one side of an associated rectifier L11...L14, L21...L24, the other sides of the rectifiers associated with each group being connected through rectifiers L1, L3 respectively, in series with a source E2 providing a D.C. reference potential and a device responsive to changes in the A.C. impedance of the arrangement and forming part of an indicating means. In addition, the rectifiers associated with each group are connected through rectifiers L2, L4 in series with a further source E1 providing a D.C. reference potential, or with the source E2. In the arrangement shown, the indicating means includes a transformer having a winding c, d connected in series with the source E2 which provides a D.C. potential normally below the biasing potentials U11 &c. Thus under normal conditions the rectifiers L11 &c., associated with the supervised devices are blocked and a high impedance is presented to the winding' c. d and the indicating means is not operated. Should a supervised device become faulty so that one of the biasing voltages falls, e.g. U11, the associated rectifier L11 is unblocked so that direct current can flow from the source E2 and a low impedance is presented to the winding c, d. from which alternating current can flow resulting in the operation of the indicating means. The rectifiers L2, L4 and the source El provide circuits between points 1 and 2 and earth of low impedance to avoid "cross-talk" should the arrangement be used for supervising telephonic equipment and also to prevent incorrect operation of the indicating means due to reverse leakage currents through the rectifiers. Fig. 3 (not shown) illustrates the use of a thermistor to amplify the voltage derived from a supervised device before application to the associated rectifier. Specification 749,442 is referred to.

Abstract: 1,122,506. Dental handpieces. E. MAVERNA. 25 May, 1966 [5 June, 1965], No. 23399/66 Heading ASR. [Also in Divisions F1 and F2] In a pressure-fluid-driven rotary tool, which tool may for example form part of a dental handpiece which includes a drill adapted to be driven by an air turbine, comprising a casing, a shaft located within the casing and journalled in two spaced-apart ball bearings, and a vaned rotor adapted to be driven by pressure fluid and mounted on the shaft between the two bearings, the outer race of one bearing is rigidly secured to the casing while the outer, race of the other bearing is fixed to a member slidably mounted within the casing, the arrangement being such that, in operation, fluid pressure causes the member to move axially relative to the casing thereby to effect relative movement between the outer races of the bearings to eliminate axial and/or radial free play in the bearings As illustrated in Figure 1, turbine rotor 1 comprises a set of vanes 2 keyed to a rotatable shaft 3 which, is adapted to carry a drill 3'. The rotor, which is enclosed in cylindrical casing 5, is adapted to be rotated by compressed air supplied through duct 4 and exhausting through a second duct (not shown), the two ducts being enclosed by handle 7. The shaft is mounted on two ball bearings 8 and 9, the inner races 10 and 11, respectively, of which are fastened to the shaft. The outer race 12 of bearing 9 is fixed to the casing; the outer race 13 of bearing 8 is fixed to piston member 14 which is non- rotatably mounted as a close fit within the casing to be slidable in an axial direction. The shaft has enlarged portions 15 and 16 which are enclosed by a chamber 17 bounded in part by portion 18 of the casing and portion 19 of the piston member; the surface 14 of the piston member upon which the pressure fluid acts thus defines one wall of the space between the two bearings and is exposed to the same pressure as the rotor, the speed of rotation of the rotor and the relative movement between the outer races of the bearings being functionally related at all times. To allow axial movement between the inner race and outer race of each bearing, an annular groove preferably is provided adjacent at least one radial end surface of the inner race of each hearing; as illustrated, grooves a and b are formed in respective surfaces of the casing and of the slidable member which abut the inner races of the bearings. A further similar annular groove c may be provided in the surface of the slidable member.
