Abstract: 1449856 Regulating I C engine fuel injection ROBERT BOSCH GmbH 21 Sept 1973 [22 Sept 1972] 44408/73 Heading F1B [Also in Divisions G2-3] A metering valve 16 in a fuel injection system is operated by a control fluid against a restoring force and the pressure of the control fluid is regulated by a device 6 in accordance with the air-flow in an intake pipe 1 as measured by an element 7 in the pipe. The valve 16 controls ports 18 connected by passages 19 to chambers 13 on one side of a diaphragm 12 which is subject in chambers 14 to the pressure of fuel fed to the valve upstream of the ports. The diaphragm 12 controls outlet passages 31 leading to respective fuel injectors. A potentiometer 8 may be actuated by the element 7 and a potentiometer 5 by a lever 21 positioned by the valve 16, the resulting signals being compared in a unit 4, e.g. including a bridge circuit, to provide a control signal for the device 6. The air and fuel flow signals may be provided by hot wires (53 and 54), Fig. 2 (not shown), located in the pipe 1 and at least one of the fuel passages between the ports 18 and the chambers 13. The fuel flow may be measured by the difference in fuel flows to the groove 17 via passage 30 and from the groove via passage 33. The device 6 comprises a valve diaphragm 40 operated by an armature 44 with an energizing coil 45 within a magnet 46. The diaphragm 40 controls the flow of fuel through a passage 38 into the valve chamber 41 and the flow of fuel from the valve chamber to the fuel reservoir 25 through the passage 49 and thus the flow of fuel to or from the control chamber of the valve 16 through the line 51. The coil 45 may be energized intermittently or continuously. The operation of the device 6 may be additionally controlled in accordance with engine operating conditions e.g. load, temperature and exhaust gas composition.

In a disc brake having a body member 10 supporting a directly operated pad assembly 14, 23 and a yoke 12 slidably mounted in grooves 13 along opposite sides of the body member 10 and supporting an indirectly operated pad assembly 15, an actuator 16 is operative between the yoke and the directly operated pad assembly and the arrangement is such that one of the edges of the directly operated pad assembly 14, 23 can abut the corresponding one of inward side edges of the yoke 12 to transfer between the yoke and the directly operated pad assembly the drag force developed at one only of the pad assemblies. The directly operated pad 14 is mounted on backing plate 23 which has a heat barrier 22 and is slideably mounted in the body member 10 between lugs 27, 28 on the body member. As shown there is a clearance between the yoke 12 and the bottom of the grooves 13 such that the drag force produced by the pad 15 acts on the backing plate of the directly operated pad 14 at P which acts at Q on lugs 27, 28 as well as the drag force produced by the pad 14 which also acts at Q. By arranging that the clearance between the yoke 12 and the bottom of the grooves 13 is small and that there is a clearance between the backing plate 23 and the lugs 27, 28 the drag forces produced by the pads are transferred to the body member 10 by the yoke at the bottom of one of the grooves 13 (at S, Fig. 3, not shown). The drag force produced by the directly operated pad assembly 14, 23 in this arrangement is applied (at R) to an inner edge of the yoke 12. The hydraulic actuator 16 has two pistons 17, 18 which operate the pad 14 and the pad 15 via the yoke 12. The turning of the yoke 12 is limited by an insert member 30.

Abstract: 1,247,516. Selective printing. IRODAGEPIPARI ES FINOMMECHANIKAI VALLALAT. 23 Sept., 1968, No. 45188/68. Heading B6F. Variable escapement mechanisms.-A typewriter carriage rack 1 meshes with a pinion 2 fixed on the shaft of a gear-wheel 3. A rack 4 is fixed to a shaft 6 which is rotatably and slidably mounted in a frame 7. Variable letter spacing is governed by the longitudinal displacement of the rack 4 and shaft 6, the degree of displacement being governed by a blade type unit step limiter 8 similar to that of Specification 998,203. The frame 7 is pivotally mounted on journals 7a, 7b and carries a blade 9 (Figs. 2 and 3). During tabulation, a lever 10 pivots the rack 4 about the axis of the shaft 6 so that the gear-wheel 3 is free to rotate. For back spacing, the frame 7 is pivoted about journals 7a, 7b, so that the rack 4 is disengaged from the gearwheel 3 which is simultaneously engaged by the blade (9). This prevents the gear-wheel 3 rotating, but allows the rack 4 to move under the influence of spring 5. The blade limiter 8 willlimit this movement so that when the rack 4 is returned to its original position, the gearwheel 3 is driven for a back spacing movement of the type-carriage by an amount equal to that allotted to the previously typed character.

Abstract: 1280040 Electric couplings REYNOLDS METALS CO 19 Sept 1969 [19 Sept 1968] 46364/69 Heading H2E [Also in Division H1] Thermal expansion joints 30 for use in an electrical power transmission system (20, Fig. 1, not shown) having an outer conduit 21 are used to join rotatable conductors 26 to non- rotatable conductors 27 spaced alternately along the system. A joint 30 comprises two spaced support plates 70, one carrying a rod 60 with a male thread 61 and the other carrying a tube 62 with a nut 63 at its free end to engage the thread 61. The plates 70 are carried by frustoconical transition members 71 attached to conductors 26, 27. On expansion of the conductors 26, 27, each conductor 26 is rotated by engagement of the thread 61 with the nut 63, thus decreasing the helical pitch of leads 55 which are wound around the tube 62 and are welded to the plates 70 at 76. A corona shield 94 is fixed at one end to one plate 70 by screws 100 entering threaded holes 96 in the plate, and is free to slide over the other plate 70 which has a plastics ring 101 in a groove around its edge.  Torsional stresses in each rotatable conduct- or 26 are prevented by having the screw thread 61 and the leads 55 spiralled in opposite senses at the two ends of the conductor, so that the whole conductor 26 rotates in the same direction. The conductor 21 is made up of longitudinal metal sections 22 which are welded together but may alternatively be non-metallic. The conductors 26, 27 are supported therein by insulating spacers (31, Fig. 4, not shown) fixed to the conductors midway between joints 30 and by intermediate spacers 44, the spacers being perforated to allow an insulating and cooling fluid such as an inert gas to flow between the conduit 21 and the conductors or joints. To prevent the conductors 26, 27 from travelling axially along the conduit 21, the central spacers (31) of rotatable conductors 26 are loosely sandwiched between annular metal plates (35) fixed to the conduit 21. The central spacer (31) of each non-rotatable conductor 27 is bolted to a similar plate (41).
