Abstract: 1495351 Fuel injection systems WE SIEMENS 28 Jan 1975 [1 Feb 1974] 3677/75 Heading F1B A device for forming a fuel/air mixture, for an I.C. engine, comprises a chamber, a duct for supplying air under pressure to the chamber, a fuel reservoir for receiving fuel, valve means for releasing a predetermined quantity of fuel from said reservoir into said duct and means for driving a desired fraction of the air in the chamber through said duct to mix with the released fuel, wherein the fraction of air is dependent upon the quantity of fuel released from the reservoir. A differential  piston has a first part 5 which fits the bore of working cylinder 1, and a second part 7 which slides in bore 10 in cylinder head 9. Duct 18 leads to passages 19 and at T.D.C. working piston 2 drives substantially all the combustion air into chamber 11, which is annular since a member 12 is mounted coaxially on the end-face of part 7. Member 12 is also stepped and slides in a correspondingly stepped bore 15 in housing 16 which is screwed into the cylinder head. An orifice 24 in the lower end of member 12 is normally closed by a spring-biased valve 23. A fuel reservoir 17 is formed by the annular space between the shoulders on member 12 and bore 15 and this space is filled with fuel at a predetermined pressure via non-return valve 28 from supply pipe 26. At the end of the compression stroke of piston 2, the differential piston 5, 7 is held in an uppermost position, as seen in Fig. I, by air-pressure acting on surface 6. A rotary valve 33, controlled from a remote position by a device 35, is turned and allows fuel to pass from reservoir 17 to bores 31, 30 and 32 and to lift valve 23 against spring 25. Piston 5, 7 is then able to move upwardly and air is forced out of chamber 11 to mix with the fuel in duct 18. In a modification, Fig. 2 fuel reservoir 17 is a central bore in valve 23, the capacity of the reservoir being determined by an overflow passage 55 and a rod 48, fixed in the housing 16. An electrically operated igniter 21 is provided.

Title: Improvements in or relating to grinding machines for paper pulp
IPC: B02C7/08
Filed: 1934-02-06
Abstract: 423,898. Paper - pulp grinding - machines. LORD, F., 26, Astbury Street, and WILBY, A. C., 5, Johnson Street, both in Radcliffe, Lancashire. Feb. 6, 1934, No. 3823. [Class 96] In a grinding-machine for paper pulp of the kind comprising a plurality of rotary grinding discs mounted on a vertical shaft to act on the pulp in co-operation with stationary discs as the pulp passes successively between them, the inlet is arranged at the lower end of the machine and the pulp is forced upwardly and is ground between shear-edged grinding blades provided only on the undersides of the rotary discs and the upper sides of the stationary discs, the grinding only taking place while the pulp is flowing outwardly from the shaft. A frame 1 carries an electric motor 2 with a shaft 3 coupled at 4 to a vertical shaft 5 supported by a ball thrust bearing 7 linked to a lever 8 fulcrumed at 9 and linked to a screw 10 engaged by a nut-wheel 11 between lugs 12 to permit the shaft 5 to be raised or lowered at will. Three stationary dished conical discs 13 are arranged one above the other round the shaft 5, the lowermost of which has a radial flange 14 attached to an inlet chamber 15, while the upper ones have inverted dish-shaped flanges 16 which fit over a lower disc 13 to form a series of chambers 17, the top disc 13 having a cover 19 provided with an outlet 20. Each disc has a central aperture 18 connecting one chamber with the next. The shaft 5 runs through all the chambers 17, glands 21, 22 forming water-tight points of entry and exit. Water leaking from the apparatus is caught in a trap disc 23 with drip channel 24 and drain pipe 25. The upper sides of the discs 13 have removable shear-edge blades 26 which co-operate with shear-edged blades 28 on the under side of discs 27 contained in the chambers 17 and mounted on the shaft 5. The upper sides of the rotary discs 27 have curved upwardly projecting radial vanes 29 while the flanges 16 have on their under sides curved radial vanes 30. Inspection doors 31 may be provided on the members 16. The conicity of the discs 13, 27 is sufficient to have a self-centring effect for the discs 27 but is not sufficient to produce any seizing effect between the blades 26, 28. The pulp is fed in at the first central aperture 18, passes outwardly between the shearing edges of the blades 26, 28 of the lowermost set of discs 13, 27, and then upwardly over the periphery of the disc 27, the vanes 29 being acted upon by the pulp to assist the driving of the disc 27, and the vanes 30 guiding the pulp to the second central aperture 18 which leads into the second chamber. Finally the pulp issues forth by the pipe 20 leading from the upper chamber 19.

Title: Improvements in or relating to electrical oscillation generators
IPC: H03K12/00
Filed: 1941-03-21
Abstract: 582,752. Pulse generating circuits. STANDARD TELEPHONES & CABLES, Ltd., and LEVY, M. M. March 21, 1941, No. 3881. [Class 40 (v)] Pulses of very short duration of low power and voltage are converted to higher power by a multi-stage amplifier of which the first stage or stages amplify the voltage while the subsequent stages amplify the power but contribute substantially no voltage amplification. The Figure shows a pulse generator in which alternating current of pulse frequency is fed to the input transformer T. Pentodes P1, P2 are fed in phase opposition, a condenser C ensuring that the voltages are slightly displaced from exact opposition. High voltages are supplied through resistances R0 so that sudden saturation is produced, but the positive voltages are limited by the resistances R0 and the negative voltages by the diodes D. In this way short pulses are produced in the common anode resistance Rp and the power consumption in the valves between pulses is reduced by the use of an alternating supply in quadrature with the voltage applied to input transformer T which in addition renders the negative pulses ineffective. The amplifying valves V, V1, V2, are arranged as cathode followers and have an alternating supply to reduce power consumption. Since the operative periods of the valves is only a small fraction of the cycle, plate voltages considerably above those for normal operation may be used, in addition bias arrangements are such that the power dissipation in the periods between pulses is substantially reduced. In addition to the use of alternating current for the anode supply, it may also be used for the screen grids of the same order of magnitude as for normal operation. The valves used are preferably of a type having a high space charge or an emitting surface not exhibiting saturation.

Abstract: 539,241. Drive of calenders for paper. SINCLAIR, H. March 1, 1940, No. 3891. [Class 96] [Also in Groups XXIX, V and XXXIV] A power transmission mechanism, which is especially applicable for driving a calendering machine for paper, or rubber, at a creeping speed when feeding in the work and at a higher normal running speed, comprises a driving-motor 10, Fig. 3, and preferably between this and the driving-shaft 20 of the machine a hydraulic coupling 12 of the kinetic type is arranged, and according to the invention the shaft 20 is fitted with brake having a brake torque characteristic rising automatically with speed the brake being made operative while the machine is started and being inoperative during normal running. The coupling 12, Fig. 3, is of the Vulcan Sinclair traction type and the impeller 16 is fitted with a conical casing 24 journalled on the shaft 18 by deep-groove ball bearings 25 provided with a sealing diaphragm of the kind described in Specification 459,071, [Group XXXIV]. The shaft 18 is coupled to the shaft 20 to which is fixed a brake disc 33 fitted with spring-controlled pivoted shoes 34 which are moved outwards into contact with a drum 40 journalled on the shaft 20. The drum 40 can be free on the shaft during normal running of the machine, but for the initial creeping drive the drum is held fixed by outer pivoted shoes 42 on levers pivoted to the machine frame and controlled by a rod 46 operated by an electromagnetic solenoid to cause the shoes 42 to grip the drum 40 and so render the centrifugal brake operative. In a modification, Fig. 5, a hydraulic coupling 12A of the kind described in Specifications 493,703, [Group XXIX], is employed and the brake consists of a hydro-kinetic brake 32A and a controllable friction brake for restraining rotation of the braking element 63, 64 of the hydro-kinetic brake. The hydraulic coupling may be dispensed with, and a driving-motor employed having a suitable torque speed characteristic of drooping form capable of driving at a creeping speed, such as a squirrel cage motor of high torque type, which may be used for low powered drives where the creeping speed condition is of brief duration. Or a stepring motor with rotor control may be employed in conjunction with a suitably graded resistancecontroller. A brake as described in connection with Fig. 3, is used with such a motor.
