Title: Improvements in or relating to electron microscopes
IPC: H01J37/141
Filed: 1952-06-12
Abstract: 711,672. Electron microscopes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 12, 1952 [June 15, 1951], No. 14840/52. Drawings to Specification. Class 39(1) An electron microscope embodies a lens wherein the magnetomotive force is such that the lower limit of magnetic saturation is reached in the polepieces, the diameter of the bores in the pole-pieces being not more than one-third of the distance between the pole-faces, and the space between the pole-faces being long enough for a focus to be located therein but as short as is compatible with the insertion of an object between the focus and that pole-face which is first traversed by the electrons. It is explained in the Specification that with this spacing, the use of a narrow bore in the pole shoes results in a more powerful lens for a given number of ampere turns but does not increase the astigmatism; the power supplies require less stringent stabilization, and for a resolving power of 60.U. the operating voltage may vary by ¢ to 1 per cent and the energizing current by -¢ per cent. In a microscope operating at 80 Kv the spacing between the pole shoes may be 1.4 mm. and the bore 0.3 mm.; this gives a focal length of 0.7 mm. and a magnification of 140; the lens requires about 3000 ampere turns and the first focus is 0.3 mm. from the pole-face.

Filed: 1974-12-03
Abstract: 1467335 Control of printers CASIO COMPUTER CO Ltd 3 April 1974 [9 April 1973] 14845/74 Heading G4H A printer incorporates means for printing special marks adjacent characters (e.g. underlining) without backspacing. Data to be printed is fed from a device 12 (e.g. a keyboard or tape reader) to a decoder 15 which produces control signals L1 &c. for printer 16, which signals operate a print head shifting device 24 after a delay 18. Characters to be underlined are preceded and followed by an underline (start/stop) code generated by a key 13: this code operates a counter 21 (or a flip-flop) whose output changes to enable a gate 19 and block a gate 20. Since gate 20 is blocked, the printhead is not stepped after a character to be underlined; instead, gate 19 and gates 25, 26 effectively apply an "underline" code 01000001 to the decoder, which outputs an underline command L n  to printer 16. Signal L n , however, operates device 24 after a delay 27 so that the next character can be printed. This procedure is repeated until the underline stop code from key 13 changes the output of counter 21 to block and unblock gates 19, 20.

Patent GB-703019-A (GB)
Title: A process for the manufacture of lactams
Filed: 1951-06-25
Abstract: Pure lactams are obtained from aqueous solutions of crude lactams saturated with a neutral salt (i.e. containing the maximum amount of salt which can be used without causing the lactam to separate, the term neutral salt meaning a salt neutral to litmus) by extraction with organic solvents or azeotropic solvent mixtures which dissolve less than 0.1 per cent. water and up to 30 per cent. lactam, in more than one stage and on the counterflow principle followed by extraction of the lactam solution obtained in one or more stages with an oxidizing or reducing solution, or a base or acid binding solution, or by adsorption by solid substances having the properties of said solutions, after which the solvent is removed.  Preferably the nature and amount of solvent is such that the lactam concentration therein does not exceed 15 per cent.  As the concentration of lactam in the aqueous phase diminishes as extraction progresses it is necessary to add neutral salt solution to maintain saturation as defined above and thus ensure that the lactam does not remain in the aqueous phase but passes into the solvent.  Impurities separate in flake form from the aqueous phase as it emerges from the preliminary extraction.  The solvent containing lactam from the preliminary extraction may then be treated with a weak aqueous solution of, e.g. potassium permanganate, hydrogen peroxide, sodium hydrosulphite, sodium sulphite, sulphuric acid, phosphoric acid, caustic soda, or lime, or adsorbed on, e.g. barium peroxide, sodium hydrosulphite, sodium bisulphate, quicklime, or ion exchangers.  In examples, detailed below, the aqueous crude lactam solution is introduced in the lower part of the lowest of three towers staggered as to height so that the solvent which enters in the lower part of the uppermost tower can flow downwards by gravity.  The aqueous solution flows from the bottom of one tower to the lower part of the next higher tower and the solvent enriched with lactam flows from the top of one tower to the lower part of the next lower tower on the usual counterflow principle. Neutral salt solution is introduced into the upper part of each tower, more salt being required in the higher tower where the amount of lactam is less.  In examples, (1) crude e -caprolactam is preliminarily extracted with a solvent mixture of 55 per cent. benzene and 45 per cent. cyclohexane, using 40 per cent. ammonium sulphate solution as the neutral salt, and the lactam solution subsequently extracted with certain of the solutions listed above or with calcium sulphite or subjected to adsorption with quicklime or with artificial resin anion and cation exchangers.  Also in examples, crude zeta-oenanthole lactam oil is extracted with the same solvent mixture using 30 per cent. sodium sulphate solution, followed by treatment with caustic soda and sodium hydrosulphite solution.

Title: Improvements in and relating to pump installations
Inventor: SHOOSMITH GUY TAITE
IPC: F04C14/06
Filed: 1960-04-29
Abstract: 985,548. Rotary pump installations. PLENTY & SON Ltd. May 1, 1961 [April 29, 1960], No. 15147/60. Addition to 810,099. Heading F1F. In a pump installation as described in the parent Specification, one of the pumps is brought into and out of operation solely under manual control. The motor (not shown) driving the first pump 10 is started by a manual control 62. On this pump reaching 90% capacity a rod 42 connected to a pressure-responsive piston in a housing 24 closes a limit switch 46 to operate through a relay 54 a starter unit 58 to start the motor driving the second pump 12. As the load further increases and the capacity of the pump 12 reaches 90%, the pump 14 is similarly brought into operation. Separate pressure accumulators 36, 38, 40 for each pump apply pressure e.g., 155, 150, 145 p.s.i. respectively, to the upper sides of the pressure-responsive pistons, so as the load falls the flow capacity of the pump 14 drops first, followed by the pump 12 which on falling to 80% capacity operates a limit switch 52 to stop the motor driving the pump 14. Similarly, on further falling off of load and the capacity of the pump 10 falling to 80% the motor driving the pump 12 is automatically stopped by the operation of a switch 42 on the pump 10. The pump 10 will however continue until stopped manually, limit stops arranged to limit the movement of the adjustable cage of the pump 10 ensures that the capacity of that pump does not fall below 3%. An adjustable bleed valve 66 in a line 64 connecting the common delivery duct 16 back to the supply source ensures a continuous flow of liquid through the pump 10. A selector switch 70 may be fitted to change the sequence in which the pumps 12 and 14 operate. Also, the pump 14 may be fitted with limit switches to allow the pumps to be changed round within the installation. The starters 58, 60 are also capable of manual operation so that each pump may be brought under manual control.

Abstract: 737,715. Heavy-ion-beam tubes. BENDIX AVIATION CORPORATION. June 1, 1953 [June 4, 1952], No. 15236/53. Class 39 (1). [Also in Group XL (c)] In a mass spectrometer of the type in which ions of different masses are separated into groups by first storing them and then withdrawing them as a bunch from an ion source 22 with velocities dependent on their masses, the masses being determined by measuring the times of flight of the different groups to a collector 24, the lengths of the groups are modified so as to be inversely proportional to the masses of the constituent ions. The time required to collect a group of ions is then independent of the mass of the ions in the group. In the ion source 22 an electron beam generated by the filament 26 ionizes gaseous molecules introduced into the space between electrodes 38 and 40. The ions stored in the space between electrodes 38 and 40 are extracted after the electron beam is cut off through the electrodes 40 and 42 by applying an accelerating field between the electrodes 38 and 40. As the ions formed into groups according to their mass pass through the electrode 40 a reverse accelerating field is applied between the electrodes 38 and 40, and ions are retracted from the groups according to the lengths of the groups remaining between electrodes 38 and 40. At the same time the field between electrodes 40 and 42 is reduced or suppressed. The ion collector 24 comprises a receptacle 56 positioned within a grounded shield 58. A screen extends across the open side of the shield. The receptacle is connected to an oscilloscope for indicating the relative times-of-flight of the various ions. Specification 713,993 is referred to.
