Title: Improvements in or relating to the separation or separate detection of charged particles having different specific charges
IPC: H01J49/42
Filed: 1958-12-23
Abstract: 904,033. Mass spectrometers. SIEMENSSCHUCKERTWERKE A.G., and PAUL, W. Dec. 23, 1958 [Dec. 27, 1957], No. 41540/58. Drawings to Specification. Class 39 (1). In a high-frequency mass spectrometer such as described in Specification 773,689, ions of different specific charges are brought into a periodic electric field the potential # of which has the general form: #=f(t).(αx<SP>2</SP>+ #y<SP>2</SP>- γz<SP>2</SP>) and an additional alternating resonance field whose frequency is approximately a fundamental or harmonic frequency of the natural oscillation of the ions of a given specific charge is superimposed on the original field and forces the given ions on to unstable paths so as to be separated out. A frequency corresponding to half the frequency of the main field is excluded. A plurality of additional fields of different frequencies may be superimposed simultaneously. Also by varying the frequency and amplitude of the superimposed fields the beat amplitude of ions of a given specific charge may be determined. The fundamental oscillation frequency of the ions is a function of its specific charge, the magnitude of the unidirectional field, the amplitude of the first applied alternating field, the magnitude of the frequency of that field and it also depends upon the electrode spacing. Since the magnitude of the alternating field, preferably of high frequency, is the only variable a proportionality constant K exists. Exact tuning is not required since in the case of small frequency differences, the ions may be made to execute beats, the amplitude of which may become so large that separation occurs. This method is particularly suitable for rapid variation of the composition of isotope mixtures. The range of separation of the superimposed field varies with the amplitude of that field.

Abstract: 1,128,711. Stacking apparatus; endless conveyers. BUTTERLEY CO. Ltd. 11 Jan., 1966 [14 Oct., 1964], No. 41865/64. Headings B8A and B8C. Blocks of concrete, &c., to be stacked are transferred from a driven endless conveyer 15 on to a free-wheeling conveyer 21 having control means such as an adjustable friction disc 22 to limit the extent of free-running thereof, on which conveyer they move closer together. The leading block on the conveyer 21 operates a switch 24 which stops the drive of conveyer 15 and permits the assembled blocks to be lifted by a gripper 27 and carried to the stacking station, which may be on a further conveyer. In the embodiment there is a pair of parallel conveyers 21 and side members 23 alongside the conveyers 21 raise the blocks from the surface of the conveyers 21 prior to lifting by the gripper 27. A switch 21A operates an interlock which prevents the conveyer 15 from moving while the members 23 are elevated. The gripper 27, which may be rotatable through 90 degrees so that alternate layers of the stack may be of different orientation, runs on a gantry 26 either parallel to or perpendicular to the direction of the conveyers 15, 21. The blocks are delivered initially to the conveyer 15 by a gripper 12 running on a gantry 11, a switch 15A being provided to ensure that the gripper 12 does not lower blocks on to the conveyer 15 while other blocks are still stationary on it. Both grippers 27, 15 may be controlled either manually or by a system of switches. Delivery of blocks to the stacking apparatus may be made by a pallet conveyer 14.

Title: Bale-forming machine and process
IPC: B29C48/94
Filed: 1964-10-19
Abstract: 1,058,058. Baling rubber by extrusion. POLYMER CORPORATION Ltd. Oct. 19, 1964 [Oct. 23, 1963], No. 42569/64. Heading B5A. An extrusion and cutting apparatus for producing blocks of deformable material, in particular blocks of synthetic rubber such as butyl rubber, comprises a continuously operating feed screw 11, a compression chamber 17 which terminates in a die 20, an expansion chamber 21 having a rapidly diverging portion 22 and a relatively slowly diverging portion 23, a horizontally reciprocable confining chamber 24 and a vertically reciprocable knife 25. The nitial cross-sectional shape of the block is determined by die (20), see Fig. 3 (not reproduced), the final cross-section being square, attained by expansion of the material within chamber 21. The block may also have a circular cross-section or be polygonal, each side of the polygon at die 20 being bowed inwardly. In operation the material passes from breaker plate 15 through chambers 17, 21 and 24, and with the parts as shown, exerts pressure on knife 25 whose supporting frame is connected to chamber 24. This pressure causes a movement of chamber 24 in a downstream direction until a contact 39 thereon operates a switch 42 to cause freeing of an hydraulic line B associated with a cylinder 13. The chamber 24, being connected by means of a link 31 and rod 30 to a piston 18 within cylinder 13, now moves relatively quickly in the downstream direction until contact 39 operates switch 43 which causes raising of knife 25 by the introduction of fluid to cylinder 27 via a line D. The knife movement operates switch 44 to cause filling of cylinder 13 via line B, and chamber 24 moves in an upstream direction until stopped by contact 39 operating switch 41. The material continues to issue from chamber 24 after retraction of blade 25 until a beam of light to a photocell 46 is interrupted, whereupon the material is cut by blade 25 consequent upon filling of cylinder 27 via line C. In the lowermost position of the blade, a switch 45 is operated to build up a predetermined pressure within cylinder 13 via line B causing movement of chamber 24 upstream until the pressure is balanced by that of the material on blade 25. The abovementioned cycle of operations is then repeated. Within the expansion chamber 21 the material is lubricated, e.g. by means of silicone emulsions or detergent solutions, introduced through conduits 32 to an annular channel 33 within die 20. If water remains on the blocks after production they are then dried, although drying may take place by direct evaporation, e.g. by using a solution of detergent in methanol. Alternatively to the above-mentioned lubricants, the walls of chamber 21 may be lined with a low friction material, e.g. P.T.F.E. Chamber 24 may be closed by a member other than blade 25.

Abstract: 1,025,674. Emission microscopes. TRUB TAUBER & CO. A.G. Nov. 13, 1962 [Nov. 22, 1961], No. 42812/62. Heading H1D. An electrostatic immersion objective for an emission microscope comprises an emitter electrode K, an intermediate electrode Z, a control electrode S and an accelerating electrode A, the bore in the intermediate electrode Z having a diameter D z  and an axial length z, each of which is at most one fifth of the distance a between emitter K and electrode Z. In a preferred arrangement, a is 3 mm., z is 0À25 mm. and D z  is 0À3 mm., so that the field between cathode K and electrode Z stays homogeneous until near the bore, and the beam almost immediately afterwards enters the field of the Einzel lens Z-S-A, electrode Z being at the same potential as anode A, and the control electrode potential being variable and less than a tenth of the anode potential relative to the cathode. The bore in electrode Z is chosen to restrict the image at the smallest magnification used, and may be funnel-shaped with its narrow part adjacent the cathode and may have rounded edges. One or more of the electrodes may be adjustably mounted for transverse displacement or relative inclination to compensate astigmatism due to lack of rotational symmetry in the bore of electrode z. An apertured screen B may be provided beyond anode A. After passing the objective, beam electrons may be deflected by a magnetic field so that negative ions alone are used for image formation. Also the polarity of the electrode potentials may be reversed for image formation with positive ions.
