Dec. 18, 1933, Nos. 35511 and 35512. Convention dates, Dec. 17, 1932 and Dec. 6, 1933. [Class 39 (i)] Electrodes comprising or combined with one or more plates with guiding holes at a standard distance apart are formed into a single structural unit on a temporary rotatable support and this unit is removed from the support and mounted, together with other units or electrodes, on glass or other insulating rods 2, Fig. 1, which extend from the base 1 of the tube and engage the guiding holes to align the unit correctly. A Wehnelt cylinder 3 in a plate 3<1>, a first anode 4, an after-concentration cylinder 5 in a plate 5<1> and a main anode 6 are assembled on a temporary support 27, Fig. 14, with interposed distance pieces 31 and are clamped together. A central rod 33 with cylinders to engage the parts 3, 5 is used to indicate, by eccentric movement on rotation of the support 27, if the electrodes are not properly centred, The electrodes are then secured together whilst on the support 27 by means of insulating rods 36, Fig. 1, with metal clips 37 welded to the plates 3<1>, 4, 5<1>, 6. The unit so formed is removed for the support 27 by means of the piece 30 and is slid on to the rods 2 of the tube. The mounting of the cylinders 3, 5 in the plates 3<1>, 51 may also be carried out on the support 27, centring being tested by rotation. A second unit comprising sets 7, 8 of deflecting plates is also formed on the support 27 and then slid on to the rods 2. Each set 7, 8 comprises three plates as described in Specification 432,209 and the plates are combined by insulating rods 40 and clips 39 and are secured to plates 9 spaced by rods 36 and engaging the rods 2. The cathode 15, Fig. 12f, may be mounted when the rest of the system is assembled and is carried by a guide 17 sliding into the cylinder 3, connection members 23, 24 for the heater circuit being carried by an insulator 22 secured at 20, 21 to the cylinder 3. In a modification, Fig. 18, the Wehnelt cylinder 3 is carried by two plates 47, 48 and contains a cylinder 52 secured to the guide 17 for the cathode 15. The electrode structure is guided in the tube by rings, the ring 45, Fig. 1, serving also to interceptions. A mica heat-shielding ring 46 is provided at the lower end. All metal parts may be formed of non-magnetic material such as phosphorbronze and are freed from gas by heating in vacuo. The Specification as open to inspection under Sect. 91 comprises also a modified cathode structure similar to that shown in Fig. 12f but with the insulator 22 attached to the guide 17. This subject-matter does not appear in the Specification as accepted.

Title: An automatic device for regulating fuel injection in an internal combustion engine
IPC: F02D1/00
Filed: 1936-12-28
Abstract: 485,487. Fluid - pressure servomotor - control systems. MITSUBISHI JUKOGYO KABUSHIKI KAISHA. Dec. 28, 1936, No. 35525. Convention date, Jan. 23. [Class 135] In fluid-pressure servomotor apparatus for controlling the amount of fuel supplied to an internal-combustion engine 1 by a fuel-injection pump 27 in dependence on the pressure in the induction pipe 5, a joint 12 comprising two or more springs of different strength is located in the return connection between the servopiston 19 and the control valve 10 so that the fuel-air ratio is automatically increased, for instance for climbing and taking- off in the case of an aircraft engine, when the induction pipe pressure and hence the engine output reaches a predetermined value. The induction pipe 5 is connected by a pipe 6 to a chamber 7 contained in an aneroid bellows 8. The servopiston 19 is connected to a rod 28 regulating the fuel-injection pump 27 by a lever 24 having a pivot 25. The lever 24 is connected to the box or casing part of the joint 12 which contains two strong springs 14, 30 and two weak springs 13, 29 arranged centrally about a disc 11 connected to the control valve 10 which is engaged by the free end of the bellows 8. The weak springs are carried in supports 32, 33 engaging the strong springs. If the induction pipe pressure varies in either direction from that necessary to maintain the apparatus in the position shown the weak springs are first compressed and a relatively high increase or decrease in the rate of fuel supply occurs which is cut down when the departure of the induction pipe pressure changes sufficiently to compress either of the strong springs. Fig. 3 shows a modified form of joint with two springs 35, 36 of different strength on opposite sides of the disc 11 and a small interposed spring engaging a seat 34.

Abstract: 915,198. Pile drivers. DE LONG CORPORATION. Oct. 20, 1959 [Nov. 28, 1958], No. 35568/59. Class 68 (2). A marine pile-driving apparatus comprises a pontoon 10 with two lateral extensions 14 at one end and four legs 16, each of which can be driven by a mechanism 22 into the marine bottom 62. At one end of the pontoon is a slot 24, and mounted on each side of the slot is a cantilevered structure 30 which extends over the end of the pontoon. Mounted on the structures 30 are two columns 34, spanned by a bridge 36, which can be driven up and down the columns by a bridge-jacking mechanism 38, and positioned in the structures are fluid pressure operated units 60 which operate guide shoes 56. Depending centrally from the bridge is a pile driving head 40 which has a pileengaging collar 46, and a conical funnel 48. Projecting laterally from one side of the bridge 36 is a platform 50 which carries a swivelling crane 52, and suspended under the bridge are two cables 54 which have eyelets at their lower ends. In operation, the pontoon is towed into position, the legs 16 put down and a pile 64 floated into the slot 24. A collar 70 which has trunnions 72 is clamped around the pile and the bridge 36 is raised to lift the pile into a vertical position, just above the marine bottom as shown in Fig. 6. The guides 56 are moved into position and the pile lowered on to the bottom. The bridge 36 is then driven down the columns and forces the pile into the ground. The crane 52 is used to operate a grab, through the opening 48 to remove soil from inside the pile. The load on the pile can be increased by pumping water into tanks 32 in the structures 30.

Abstract: 1443931 Automatic positioning M KONDROLLOCHIS 2 Nov 1973 [3 Aug 1972]  36292/72 Heading G3N A main carriage 12 is movable in the X direction and supports one or more auxiliary carriages 18 which can traverse its length each having an arm 22 supporting a load [e.g. a tool]23 movable in the X direction relative to carriage 18. X and Y position control data causes carriage 18 to rapidly traverse the carriage 12 to a desired Y position, the X data determining the position of a light beam [or taut wire]L. As the light beam moves rapidly to its new position, photo-detector [or inductive detector] 36 mounted on support arm 22 controls motor 24 via a fast servosystem (not shown) to keep the light beam and detector 36 aligned ensuring that the arm follows the light beam, providing a rapid X co-ordinate of load motion in accordance with the light beam movement. Deviation of arm 22 from a pre-set position relative to carriage 12, detected by potentiometer 38 controls operation of a relatively slow servosystem driving the main carriage in the same direction as the light beam movement, thus following up the load X motion, until the pre-set position is again retained. The light beam is provided by a source 34 mounted on carrier 44 movable in the X direction relative to main carriage 12. A pick-up (P), Fig. 2 (not shown) detects movement of the main carriage 12 with respect to rails 14, such position signal, and the X data by means of a comparator and amplifier, controlling a servosystem for motor 32 positioning the carrier 44, which thus moves relatively to the rails 14 in accordance with the X input data, any motion of the table 12 being compensated by motion of carriage 44 relative to table 12 in accordance with the pick-up signals. A further light beam L 1 , by means of a photo-detector and prism arrangement (not shown) provides control of motor 42 rotating the beam L to keep it perpendicular to L 1 . Detector 36 may be a pair of photo-cells in a bridge arrangement. The system is applicable to positioning control in three dimensions. The load may be that of a gantry crane, or the machine may be a profiling or flame cutting machine. The control data is derived from a numerical controller, photoelectric line tracer, or a template follower. The light sources may be lasers.
