Patent FI-974307-A (FI)
Inventor: RAESAENEN JUHA
IPC: H04W92/02
Filed: 1997-11-24
Abstract: The invention relates to a method for setting up a data link, wherein an end-to-end link comprises at least two separate legs (402, 403) with error correction protocols. The legs may have different physical layer connections or their error correction protocols (V. 120, RLP) may be different. An interworking function IWF according to the invention that is located between these legs (402, 403) is integrated such that the legs can communicate with each other during set-up of traffic channel in order to exchange data compression parameters. The IWF intervenes in an end-to-end data compression negotiation, performs protocol conversions on messages transmitted from one leg to another, synchronizes the legs, if required, by delaying the set-up of the faster leg and the compression negotiation, modifies the compression parameters provided by the legs, if required, and if the end-to-end data compression negotiation fails, it may set up data compression on only one leg.

Title: A thermionic valve for use with a circuit for amplifying rectifying or generating electric wave oscillations
IPC: H01J21/14
Filed: 1944-01-20
Abstract: 571,678. Thermionic valves and circuits therefor. CLEVELAND, G. R. E. Jan.. 20, 1944, No. 1091. [Classes 39 (i) and 40 (v)] A beam - plate tetrode has an anode a, Fig. 5A, formed with a tongue t projecting between the beam plates b toward the cathode c. The tongue improves the focusing and deflecting action of the field between the anode and beam/plates; this action may also be assisted by 'strips w, y welded to the control grid g and screen grid s respectively, in line with the tongue t. Screens p<1>, p<2>, p3 confine the electron beam to the active parts of the electrodes. The valve is employed in a rectifying circuit with series anode and beam plate impedances Ra, Rb, Fig. 1, the anode impedance Ra being byepassed by condenser C1. In operation, the beam plates are initially more positive than the anode, and this voltage difference controls the sharing of current between these electrodes. A received signal will not affect the anode voltage, owing to condenser C1 but will affect the beam plate voltage, and as a result the dynamic characteristic of the anode current is much steeper than the static characteristic and goes down to a sharp cut-off point corresponding to complete deflection of the split beam away from the anode. To prevent distortion due to movement of the characteristics at the rectified frequency, portions of the rectified output may be fed back to the beam plates and to the grid ; distortion may also be reduced by continuing the beam plates right behind the cathode, as shown in dotted lines in Fig. 5A. Circuits for amplification and oscillation are also described.

Abstract: 536,117. Raising &c. liquids &c. HIGHFIELD, J. S. Jan, 18, 1940, No. 1115. [Class 102(ii)] In apparatus for pumping corrosive or other liquids, liquids containing solids in suspension, or solid material capable of flowing, comprising a closed vessel 1 supported from a balance beam 11 so counterweighted, as at 16, that the vessel rises when empty, a non-return inlet valve 2 which allows the vessel to fill when in the raised position, and a balanced position or other valve 20 actuated by the rising and falling of the vessel to control the discharge of the material from the vessel when the latter descends, an arm 17, weighted as at 19, is arranged at such an angle to the beam 11 that it comes into action to assist the upward movement of the vessel after that upward movement has commenced under the action of the counterweighted balance beam. The closed vessel may be spherical or cylindrical, and it may be immersed in the material to be pumped, or the material may flow into it by gravity or be forced or drawn into it. The vessel may be discharged by gravity or by means of compressed air or other gaseous fluid admitted by the valve 20. In the form shown in Fig. 6, in which suction is applied to the closed vessel, a heavy float 34 rests on a support 34a fixed to the pipe 33 and holds the vessel 1 in a lowered position when the liquid level falls below a pre-determined limit, thereby serving as a safety device. In a further modification, the balance beam carries two closed vessels, each serving as a balance weight (16) for the other, the balance weight 19 being retained.

The paint is applied preferably while the filament is warm. The coated filament is mounted in a bulb which is then exhausted, and the filament flashed by applying a voltage slightly higher than that required in normal use so as to produce a smooth coating of thorium. Carbon dioxide and other gas may be cleaned up by magnesium. According to the Provisional Specification, the binding agent may consist of gum or a solution of camphor in alcohol.

Abstract: 1,254,010. Organotin mercapto carboxylic acid ester halides. ARGUS CHEMICAL CORP. 10 Dec., 1968 [19 Dec., 1967 (2)], No. 1652/71. Divided out of 1,254,009. Heading C2J. [Also in Division C3] The invention comprises organotin mercapto carboxylic acid ester halides of the general formula wherein n is 1 or 2; x is 0 or 1; m is 1-4; R is a hydrocarbon radical having 1-18 carbon atoms; R 1  is an organic group derived from a monohydric or polyhydric alcohol having 1-4 hydroxyl groups and 1-18 carbon atoms; R 2  is R or S-Z-(COOR 1 ) m ; X is halogen; Z is an alkylene radical carrying the S group α or # to a COOR 1  group, having 1-5 carbon atoms and optionally containing additional groups which may be carboxylic acid and ester groups, carboxylic acid salt groups and mercapto groups. The compounds are prepared by reacting an organotin halide in the presence of sufficient water or solvent to form a suspension or solution with a less than stoichiometric amount of a mercapto acid ester and an alkali or alkaline earth metal base in an amount stoichiometrically equivalent to the mercapto ester at a pH less than 10 and separating the organotin halide from the aqueous portion. The compounds are used as stabilizers for polyvinyl chloride resins, including any polymer formed at least in part of the group wherein X is H or Cl and having a chlorine content in excess of 40%. Suitable polymers are P.V.C. homopolymers, after-chlorinated polyvinyl chlorides, copolymers of vinyl chloride with other monomers, or mixtures of polyvinyl chloride with other synthetic resins. The stabilizers are incorporated in amounts from 0À5- 10% by weight and additional supplementary stabilizers, e.g. polyvalent metal salts, epoxy compounds and phenolic antioxidants may also be incorporated in the resins. Impact modifiers and plasticizers may also be added to the resin compositions. The compounds improve the resistance of polyvinyl chloride resins to deterioration when heated at 350-375‹ F. Mixtures of diorganotin and mono-organotin halides are particularly preferred.

Abstract: 858,349. Parametrically-excited resonators. NIPPON TELEGRAPH & TELEPHONE PUBLIC CORPORATION. Jan. 16, 1957 [Jan. 16, 1956], No. 1716/57. Class 40 (9). [Also in Group XXXVI] A parametrically-excited resonator comprises non- linear capacitive elements which are constituted by semi - conductor rectifiers utilizing germanium, silicon, selenium or copper oxide. The basic circuit is shown in Fig. 5 in which a resonant circuit comprises a centretapped linear inductor L and two semi-conductor rectifying elements D1, D2, the semiconductor elements being negatively biased over a resistor R by a D.C. potential E0 at an operating point such that a large capacity variation is obtained when the resonator is parametrically excited by a fundamental alternating potential applied to terminals T1. The subharmonic oscillation from the resonator, which is intended for use as a logical element in a computer or as a frequency divider, is obtained at terminals T0 from a secondary winding L0 on the inductor. Several resonators may have their semi-conductor elements constituted by distinct regions of a common flat body, Figs. 7a and 7b, which comprises semiconductor zones 1, 2 of opposite conductivity type, the separate elements being defined by intersecting grooves 3 of greater depth than the PN junction. The resonator may alternatively use a bridge arrangement of semi-conductor elements D1-D4, Fig. 9, which are connected to the fundamental alternating potential e and to the inductor L as shown. In this arrangement the separate semi-conductor elements are again constituted by discrete regions of a common semi-conductor body, Fig. 10, and are formed by mutually perpendicular grooves 3, 4 on opposite body surfaces which pass through the junction between the different conductivity zones 1 and 2.
