Title: Method of obtaining high mass resolution with ICR measuring cells
Inventor: JERTZ ROLAND
IPC: H01J49/00
Filed: 2009-11-30
Abstract: The invention relates to methods for the acquisition of mass spectra with maximum mass resolution in ion cyclotron resonance measuring cells. The compensation potentials of an ICR measuring cell with compensation electrodes are adjusted so that they are optimal for acquiring mass spectra with maximum mass resolution. The DC potentials at the compensation electrodes are optimized in such a way that the longest possible usable image current transient is created. The clouds of ions circulating round their cyclotron track are held together over a long period by the resulting potential distribution. Depending on what kind of ion mixture is involved, transients from 10 to more than 20 seconds long are created, from which mass spectra with a maximum mass resolving power without peak coalescence can be obtained.

Title: Solid delay line and method
IPC: H04L12/54
Filed: 1964-03-10
Abstract: 1,038,651. Electro-mechanical delay lines. CORNING GLASS WORKS. March 10, 1964 [March 18, 1963], No. 10084/64. Heading H3U. In an ultrasonic electro-mechanical delay line of the kind comprising a flat plate of polygonal outline, and in which two of the facets on the periphery of the plate serve as input and output facets supporting respectively input and output transducers adapted to launch and receive transverse mechanical waves vibrating parallel to the major surfaces of the plate, the plate is so shaped that waves launched from the input transducer are reflected from one or more reflection facets before being received at the output transducer and the angle of incidence of the waves on the reflection facets are in all instances greater than the critical angle for the medium and in at least one of the reflections greater by less than two degrees, and acoustic absorbing material is attached to the reflection facets between the points at which desired reflections occur. Fig. 1 illustrates a solid delay line comprising input and output facets supporting respectively input and output transducers 24, 26 constituted by piezo-electric material such as quartz, barium titanate, a lead-zirconate lead-titanate mixture or potassium sodium niobate, oscillating in the thickness shear mode. The delay medium may be fused silica or an alkali-lead-silicate glass, as described in Specification 990,265. The ray paths in the medium are illustrated in Fig. 2 and in between the points of reflection at the periphery of the medium there are arranged acoustic-absorbing elements 28 composed of suitable material such as lead, tin or an indium-tin alloy comprising 60% indium and 40% tin. In a particular example, the critical angle for the medium was 39 degrees. The angle incidence for the first reflection was consequently chosen to be 39 degrees 30 minutes so that substantially all spurious signals to one side of the main beam impinged on the first reflecting surface at an angle less than the critical angle and were consequently dissipated. The situation of the sound absorbers was such as to limit the signals to the main beam only. By this means considerable improvement of signal-to-noise ratio was achieved. In the arrangement illustrated in Fig. 5 the outline of the plate is so chosen that successive reflections take place at an angle of incidence close to the critical angle whereby spurious signals to both sides of the main beam are dissipated.

The Li content of the surface zone is proportionally less than in the glass base, and the concentration of the alkali metal (a) is greater in the surface zone than in the interior of the glass.  The base glass may have as percentage composition by weight, Li2O, 2-10; Na2O, 2-15, the total Li2O + Na2O preferably being at least 5%; ZnO, 2-15; Al2O3, 10-30; SiO2, 45-75, and may also contain 0-1% of Sb2O3, As2O3, Na2SO4 NaCl and NaF 0.1-1% K2O, and up to 2% of any of CaO, BaO, B2O3, SrO, PbO and TiO2, not more than 10% in total of non-essential oxides being present.  The surface of the base glass is contacted with a salt of an alkali metal (a) having atomic diameter greater than Li, whereupon this metal (a) is exchanged for Li and any other alkali metals of smaller diameter than (a) at temperatures below the glass strain point, i.e. usually below 1100 DEG  F.  The metal (a) penetrates to a depth of 30-400 m or more, (a) may be e.g. Na, K, Rb or Cs, present as sulphates, nitrates, chlorides, fluorides or phosphates. The base glass article, preferably preheated, may be immersed into a bath of molten salt of (a) or may be coated with the salt and then heated to melt the salt, or the salt may be supplied mixed with a diluent in the form of a paste.  The treated article is then cooled and may be rinsed.  A series of treatments may be given, e.g. first with an Na salt, then with a K salt, and then, possibly, with Rb and Cs salts. Between successive treatments the glass may be cleansed with or without prior cooling, e.g. by use of aqueous rinsing, preheated gas, or absorbing clay or silica powder.  The article may be a plate or sheet; a sheet 0.090 inches thick may be bent around a circle of 30-inch radius. Reference has been directed by the Comptroller to Specifications 966,731 and 966,733.

Title: Improvements in compensating mechanism for vehicle brakes
IPC: B60T11/06
Filed: 1923-04-14
Abstract: 215,178. Bentley Motors, Ltd., and Burgess, F. T. April 14, 1923. Force - transmitting mechanism.- The primary and secondary members of brake-equalising mechanism are frictionally connected together so that relative movement between them will only occur when a high resistance is afforded' to the movement of one of the secondary members. Disadvantages arising from unequal resistances in the individual brake mechanisms are thus obviated. The invention is shown applied to a system for applying the four brakes of a vehicle from a lever B through a central balancing beam C, arms F, G on sleeves D, E, further arms B<3>, B<4> carried by the sleeves, right and left beams C and connections H, J, P, R leading to the brakes. All the secondary members F, G, H, J, P and Rare clutched to their respective primary members B, B<3> or B<4> by means of bolts K passing throughcurved slots Z in the secondary members, pressure between the surfaces being exerted by springs L and nuts. When the lever B is actuated to apply the brakes, the members F. G move with it until one brake is applied, relative movement between the parts then resulting in the usual way, this being permitted by the slots 'Z. With this construction the brakes also release equally. According to the Provisional Specification, the invention may also be applied to bevel or spur balancing-gear or to pulley-andcable equalising-mechanism. In the former case, the driving and driven members would be frictionally clutched together, and in the latter, the pulley would be provided with flanges pressed together by springs to grip the cable to create the necessary friction.
