Patent EE-200100101-A (EE)
Inventor: MATTISSON SVEN ERIK
IPC: H04L7/04
Filed: 1999-08-17
Abstract: Methods and apparatus for performing synchronization and DC-offset compensation in FM transmission systems significantly reduce the overhead associated with transmitting a conventional digital preamble at the start of each of a succession of transmitted digital data packets. According to exemplary embodiments, a multi-part digital preamble includes a short, substantially DC-free leading part followed by a code-protected synchronization part which is not necessarily substantially DC-free. The leading part provides for coarse DC offset estimation and synchronization, while the coded synchronization part carries timing and/or other useful information which can be unique for each packet. One or more substantially DC-free trailing parts follow the synchronization part, or are included in the synchronization part itself, and provide for fine tuning of the DC-offset estimate. Since the substantially DC-free leading and trailing parts are extremely short, and since the synchronization part carries useful information, the overhead associated with a preamble according to the invention is significantly reduced as compared to a conventional, entirely DC-free, preamble.

Abstract: 3447. Haddan, R., [Allison, J. W.]. Feb. 9. Incandescent vapour lamps. - Figs. 2 and 3 show a lamp with one burner, but, preferably, two or more are supplied from one vaporizer and mixing-chamber. The vaporizer consists of a tube G, Fig. 5, to which the oil is supplied by a pipe controlled by a cock. The escape of vapour is regulated by a needle-valve b which passes through a protecting-tube z and is operated by a sleeve G<2> in which is cut a helical groove engaging a pin c projecting from the block G<1>. By rotating this sleeve by means of an arm C<2>, the needle b is adjusted. The upper end of the vaporizer is situated in an air-supply pipe F and the vapour in passing through the vertical pipe into the mixing-chamber D draws in air through the pipe F, The pipes F and F<1> support a hood E which directs the heated products on to the chamber D. The latter is supported on pipes C, C through which the mixed vapour and air reach the burner or burners. The vaporizer is easily removed for cleaning, being supported by a pin d in a slot in a sleeve depending from the burner chamber. I is a cup to hold alcohol or the like which is burnt to heat the vaporizer before lighting the lamp.

Abstract: 4388. Courtier, J. March 1. Lamps, actinic.-Relates to a method of producing flash lights for ordinary photography, or a succession of flash lights for kinematographic p h o t o - graphy, by volatilizing metal wires by the electric current. A number of different arrangements are described. In one arrangement. Fig. 2, the wire a is fed forward by two rollers f till it comes in contact with two plates b, c forming the terminals of an electric circuit. At the instant of double contact the Wire is volatilized, and gives the flashlight. In other arrangements, the contact-terminals of thee]ectric circuit are tW'orollers,or two insulated flanges of a single roller. In the later case, short lengths of wire are woven in asbestos cloth, which is fed by rollers so as to bring the ends of each wire in succession in contact with the terminals, thus giving a regular series of flashes. The lengths of wire may be fixed radially on a rotating cylinder and make contact with a fixed plate, or they may be stretched across a dropping frame like the rungs of a ladder. For powerful lights, several wires are volatilized simultaneously.
