Patent GB-1335733-A (GB)
IPC: F02D3/02
Filed: 1971-01-19
Abstract: 1335733 Spray carburetters ROBERT  BOSCH GmbH 19 Jan 1971 [21 Jan 1970] 2670/71 Heading F1B Fuel injection system, for mixture-compression spark-ignited I.C. engine having continuous injection into the manifold comprises a measuring element and a butterfly valve in series in the inlet manifold, the measuring element being movable in proportion to the air-flow through the manifold against a constant return force, by the pressure difference upstream and downstream of the element and actuating a fuel metering valve to apportion the fuel according to the air-flow, and having parts of the inlet manifold which are upstream and downstream of the measuring element connectible by a further valve which opens against a closing force as soon as the pressure differential exceeds the value required to move the measuring element. Combustion air is drawn through a filter 2 into an inlet manifold 3 which is joined by a flexible section 5 to a further rigid section 6 containing a throttle valve 7. At the mouth of the first section 3 is a measuring element 4, pivotally mounted on an arm 10, which is itself pivoted at 11. There is a lug 12 on the arm which actuates a fuel metering valve 14. The valve receives fuel from a pump 18 which draws from a tank 20. A relief valve 23 controls the pressure in the delivery line 21. Output lines 24 each lead to a separate injection nozzle. The air flowing into section 3 of the manifold moves the measuring element 4 and rotates the arm 10 against the resistance of a spring 15 which has a flat load/deflection characteristic. When the air-flow is such that the force it exerts on the measuring element is greater than the force required to overcome the spring 15, the element rotates about its pivot 9 against the force of a spring 8, allowing the free passage of air and preventing excessive enrichment of the fuel which would result in an increase in toxic compounds in the exhaust gases. In a first modification, the measuring element is fixed on the arm 10 and there is a by-pass passage around the divergent portion of the first section 3 of the inlet manifold. At the downstream end of the by-pass is a spring- loaded valve which opens to allow part of the airflow to by-pass the measuring element. The spring may be attached to a temperature-sensitive element to permit an enriched mixture during cold operation. In a second modification there is a port through the measuring element which is closed by a spring-loaded disc valve. In a third modification, Fig.4 (not shown) the measuring element is mounted to be slidable along the axis of section 3 of the inlet manifold, the axial movement of the element being transmitted by a thrust rod to the fuel metering valve. The element is mounted on the thrust rod and is itself slidable therealong against the pressure of a spring. When the air-flow exceeds a predetermined amount, the spring is deflected so that there is lost-motion between the element and the thrust rod.

Title: Improvements in or relating to electrical musical instruments
IPC: G10H5/02
Filed: 1945-02-07
Abstract: 623,725. Electrical musical instruments. COMPTON ORGAN CO., Ltd., J., and BOURN, L. E. A. Feb. 7, 1945, No. 3119. [Class 88 (ii)] An instrument having a plurality of tone generators which are made to speak selectively has potentiometers controlled by the keys connected across bus-bars whose potentials are controlled by stops, and tappings on the potentiometers control the speech of the generators. In the embodiment described, the tone generators 7, each supplying a note and its harmonics, may be controlled as described in Specification 613,414, and each frequency is fed over a lead 8 to the control grid of a valve 9. The grid potential is normally below cut-off, but when key contacts 1, 2 close on to bus-bars 3, 4, they connect a potentiometer 5 across them so that the tapping 6 raises the potential to render the valve conducting. The potentials of the bus-bars 3, 4 are determined by stops and consequently the grid potentials of the valves supplying the various harmonics, obtained from the potentiometer 5, are similarly determined and the harmonics may sound at any predetermined strength. If desired, the odd and even harmonics may be connected to two separate potentiometers connected across separate pairs of bus-bars and instead of having one potentiometer with several tappings, individual potentiometers may be used. Specifications 613,812 and 822,910 also are referred to.

Abstract: 1300375 Clamping workpieces VEREINIGTE FLUGTECHNISCHE WERKE - FOKKER GmbH 23 Jan 1970 [24 Jan 1969] 3480/70 Heading B3B A method of fixing workpieces to a mounting plate comprises providing fixing holes at regular co-ordinate intervals in the plate, securing jig units 5.0, 5.1, 5.2, &c to the plate, and using the jig units to secure a workpiece. The jig units 5 are positioned on the plate by using a representative plan 14 on which the hole pattern is shown and on which is marked representations of the jig units. A set of templates 7.0, 7.1, 7.3, &c. representing the various jig units are provided for use in marking the plan 14. The holes are represented on the plan 14 by circular quadrant and the templates include the position of the holes. Intermediate holes may be provided on the co-ordinate pattern of holes. The holes may be provided on a plate which is supported on a further plate which is then carried by a machine table. Alternatively the holes may be provided on the machine table. Various forms of jig units are described. Unit 5.0 (Figs. 18, 19, not shown) comprises a base plate in which is rotatably mounted a dowel through which passes a member 34 which has screw clamping means at its free end (Figs. 20, 21, not shown). Unit 5.1 (Figs. 14, 15, not shown) has a base to which is attached an exchangeable dowel. Clamping means on the dowel include a nut, a sleeve and a pair of washers. Unit 5.2 (Figs. 16, 17, not shown) includes a base-plate on which is laterally slidable a slide member which carries a dowel. The dowel is eccentrically arranged on the slide member so that re-orienting the unit doubles the adjustable range of the position of the dowel. Unit 5.3 (Figs. 22, 23, not shown) includes two superimposed laterally slidable members so that the dowel can be adjusted along two co-ordinates. In Figs. 24, 25 (not shown) a unit has a rotary dowel which is clamped in its required orientation and includes a swinging vacuum clamping plate (42) having a spherical seat.

Class 110(3) [Also in Group XII] A hot gas turbine power unit comprises a combustion chamber connected to an inlet nozzle scroll 30 for the turbine and to an air supply duct comprising an outer scroll 31 which encloses the nozzle scroll to define therewith a flow channel 32 at the periphery thereof, a flame tube 42, Fig. 9, positioned in the flow channel and connected at one end to said nozzle scroll, a fuel nozzle 41 operatively associated with the other end of the flame tube and and flow passages for feeding air from the flow channel to the interior of the flame tube. The unit comprises casings 10, 11, 12. Figs. 6 and 7, which are bolted together as shown and provided with a flange 89 for attachment to an electric generator, pump or fan. The turbine casing 10 comprises an end wall 17 removably secured to a ring 24 which includes a nozzle box 25. The turbine rotor 47 is bolted to a quill shaft 49 which is journaled in anti-friction bearings 52, 53 and is adapted to drive a reduction gear 95 through a torque shaft 108 and a pinion 104. The gear 95 has an auxiliary driving shaft 98 connected thereto, the speed of which is controlled by an overspeed switch of the mechanical inertia type. The shaft 98 is adapted to drive a gear type oil pump 124, an auxiliary fan 117, a power takeoff shaft 127 and a gear type fuel pump 125 having a filter and a relief valve assembly. The fan 117 may supply air for cooling, the unit or for use in a heat exchanger or an oil cooler 120. The speed of the turbine is controlled by an axially slidable nozzle ring 57 mounted on circumferentially spaced stems 59. The stems are moved against the action of springs 61, which normally maintain the nozzle ring 57 in the inoperative position, by rocker arms 66. The rocker arms are actuated by a rotatable sleeve 73 which surrounds the bearing support 23 and has cam flights 72 adapted to drive wheels 71 carried by the rocker arms. The sleeve 73 is controlled by a rod which is actuated against the action of an associated spring by a diaphragm connected to a source of fluid pressure. The oil pump supplies oil through passages 129, 13B and a nozzle 134 to the sleeve 73 which has openings communicating with the bearings 52, 53. A branch duct 135 conducts oil to bearings 105 and hence through a duct 136 to a bearing 106.
