Title: Improvements in and relating to apparatus for separating charged particles of different mass-to-charge ratios
IPC: H01J49/38
Filed: 1951-11-30
Abstract: 698,850. Heavy-ion beam tubes. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 30, 1951 [Dec. 2, 1950], No. 28162/51. Class 39(i) A device for separating charged particles, i.e. ions, of different mass-to-charge ratio comprises a source of ions, an electrode for collecting such ions which have a predetermined ratio of mass-tocharge, means for producing an alternating electric field in the vicinity of the source of ions, and an electrostatic field in the path between the source of ions and the collecting electrode, there being also provided a means for grading the electrostatic field so that at any point of the path the increment of the field strength is substantially linearly related or the voltage is substantially parabolically related to the distance of that point from the source of ions, and a means for detecting or measuring the current caused by the ions impinging on the collector electrode. In the embodiment shown in Fig. 2 a thermionic filament 19 surrounded by a light-shield 24 projects electrons into an electron-trap electrode 27 and produces ions by collision. Grading electrodes are arranged on either side of the ion source and are connected together internally by resistances so that when a battery 61 is connected between the outermost grading electrode 43, 47 and the innermost electrodes 30, 31 a parabolic electrostatic field is-produced between the ion source and the collector electrodes 13, 14. A high frequency alternating potential is applied between electrodes 30, 31 from an oscillator 38 and it is explained in the Specification that, owing to the parabolic field, only ions of a particular charge to mass ratio can reach the collector electrodes, the particular charge to mass ratio depending on the frequency of the oscillator 38. Magnetic focusing coils 69, 70 may be provided. In a modification, Fig. 4 (not shown), the alternating potential is applied in series with the battery 61 between the inner and outer grading electrodes. In a further modification, Fig. 8 (not shown), the ion source is displaced to one side of the median plane of the device and the alternating potential is applied between two grading electrodes adjacent the median plane. In another embodiment, Fig. 3, the grading electrodes are omitted and the parabolic field is obtained by making the collecting electrodes 75, 76 in the form of hyperboloids of revolution; the alternating field may be applied between two electrodes 30, 31, or these may be omitted and the alternating potential is then applied to the collecting electrodes in series with the battery 61, Fig. 7 (not shown).

Title: Improvements in refuse collecting vehicles
IPC: B65F3/20
Filed: 1948-11-06
Abstract: 651,636. Loading refuse vehicles. EAGLE ENGINEERING CO., Ltd., MEATS, W. H., and McGETTIGAN, D. Nov. 6, 1948, No. 28887. [Class 78 (iv)] Refuse loaded into the body of a refuse vehicle is compressed by a plate 9 suspended from the rear end of a carriage 6 sliding by means of blocks 7 on guide rails in the upper portion of the body. The plate 9 is normally held in a substantially vertical position by a pair of links 10 pivoted at 11 to the carriage 6 and each carrying a pin 12 normally locked in the lower end of a slot 13 in a bracket 14 on the plate 9. Thus when the carriage 6 is traversed along its guides by a hydraulic ram 4 pivoted to a cross-member 3 of the body and at 5 to the carriage the plate 9 compresses refuse deposited in front of it. The pin 12 may be freed to slide in the slot 13 by turning a handle 15 which withdraws a bolt holding the pin 12 and also turns a shaft 19 at each side of the plate 9 so that plates 21 on the shaft are moved to a position in which they may engage acuate stops 22 on the body. If the ram 4 is now operated the movement of the carriage 6 causes the plates 21 to engage the stops 22 and turn the plate 9 about its pivot to the carriage to the position shown in dotted lines, the pin 12 riding up the slot 13. In this position the plate 9 leaves the rear of the vehicle clear so that the refuse may be unloaded by tipping the body. The means for locking the pin 12 at the bottom of the slot 13 comprises bolts 24 (Fig. 3), lying across the slot 13 but adapted to be withdrawn by arms 23 on a shaft 16 operated by the handle 15. The shaft 19 carries a pin 18 with a ball head which engages between the prongs of a bifurcated arm 17 on the shaft 16.

Title: An angular accelerometer
IPC: G01P15/11
Filed: 1959-08-26
Abstract: 900,551. Accelerometers. SIEMENS - SCHUCKERTWERKE A.G. Aug. 26, 1959 [Aug. 27, 1958], No. 29253/59. Class 40 (1). An angular accelerometer comprises a highlyrestrained oscillatable mass system mounted non-frictionally at its centre of gravity and associated at each end with a non-frictional electrical pick-up to measure its deflections. Preferably the mass system is symmetrical to avoid temperature drift of the centre of gravity, and the oscillatable system is so restrained that it has a high natural frequency compared with the accelerations to be measured. In the simplest form (Fig. 3, not shown) the system comprises a beam supported at its centre by knife edges and carrying at each end an I-shaped member restrained on each side by a spring. Displacements of the members are sensed by E-type transformers which give no output when the beam is at rest but give series-aiding outputs when the beam is deflected by angular acceleration of its support. In an improved version (Fig. 4) the beam 5 carries two light armatures 8, 9 and is mechanically coupled at 10 to a further beam carrying the masses 12, 13 and restraining means 14. A deflection-amplifying mechanical linkage can be used to connect the two beams (Fig. 5, not shown). Reduction in the total mass of the instrument (important in aircraft) can be achieved by the arrangement of Fig. 6. Here the cores of the E-type transformers form the masses, being rigidly connected at top and bottom by connecting-pieces 27, pivoted at 26 and restrained at 14. The mechanical coupling 22, 24, 23 ensures that the cores and armatures move in opposite directions. If J 1  and J 2  are the respective moments of inertia of the two oscillatable systems the sensitivity will be a maximum if the mechanical transmission ratio is ¢#J 1 /J 2 . The restraining means for the system may be formed by crossed leaf-springs used as the supports for the beams. Alternatively there may be used damping coils fed with D.C. obtained from the pick-up via an amplifier. Overall damping can be produced by immersing the device in a liquid.
