Title: Curable casting compositions
Inventor: MAIER UWE
IPC: C08K3/013
Filed: 1994-01-05
Abstract: A curable casting composition for producing plastic molded articles comprising a liquid, monomeric acrylate component is proposed, and also a process for producing it, wherein the time-consuming step of producing the sirup can be dispensed with, while, on the other hand, too rapid settling and sedimentation of inorganic particles can be reliably prevented.  To this end, it is proposed that the casting composition comprise in addition to a liquid, monomeric acrylate component, a proportion of a particulate plastic material, a proportion of a particulate inorganic material and, if necessary, a crosslinker.    The total content of particulate plastic material and particulate inorganic material should be approximately 45 to 85 % by weight, preferably 60 to 70 % by weight of the casting composition, with a minimum content of 8 % by weight of particulate plastic material.

Title: Apparatus and method for cryptographic system users to obtain a jointly determined, secret, shared and unique bit string
Inventor: MOREAU THIERRY
IPC: H04L9/00
Filed: 1995-08-23
Abstract: Two users of a cryptographic system use the present invention when their respective processors need to get a jointly determined, secret, shared, and unique bit string. The present invention is effective and most useful when used over an insecure means of data transmission. After completion of the secret key exchange according to the present invention, the users proceed with further cryptographic exchanges which may use the jointly determined, secret, shared, and unique bit string produced by the present invention. The shared bit string produced by the present invention is a simple transformation of a sequence x0, x1, x2, ..., xt-1 produced by the "x2 mod N" pseudo-random number generator. Secrecy is achieved by disclosing selected information about this sequence, in such a way that the sequence can be computed by both participants in the secret key exchange but by no one else. It is a distinctive characteristic of the present invention to provide a means of cryptographic authentication of user A to the benefit of user B with no more processing and little more precautions than what is required for the secret key exchange only.

Title: Laser-welding techniques using pre-heated tool and enlarged beam
Inventor: KINSMAN KENNETH GRANT
IPC: B23K26/06
Filed: 1995-02-02
Abstract: A laser processing method establishes initial coupling between the laser beam and workpiece by irridiating an intermediate tool positioned adjacent the workpiece. The tool is more absorptive at the laser wavelength than the workpiece so that the efficiency of energy transfer is increased. Subsequent processing is performed by relative movement between the workpiece and beam, either independently of the tool or in conjunction with the tool. During furtheur processing, the beam diameter is increased to be greater than the thickness of the workpiece to enhance the further processing.
Patent CA-2182935-A1 (CA)
Inventor: MIZUNO KIYOSHI
IPC: H04L12/46
Filed: 1996-08-08
Abstract: A source position detecting method and a communications system, communications equipment and relay suitable for implementing this method. When relaying a coded data signal from one individual network to another individual network, a first relay, for instance, increases the length of preambles by 1 and when relaying to the next individual network, a second relay, for instance, decreases the length of preambles by 2.      Increment/decrement processing of the length of preambles can be carried out without decoding the main body of the coded data signal. Alternatively, preamble duration shortening accompanying the relay can be utilized and signal distortions accompanying signal transmission such as group delay and signal strength attenuation can also be utilized. Without processing the data at the relay, the destination equipment can obtain data concerning the position of the source equipment which transmitted the data signal, such as data concerning the transmission route of the data signal.

Title: Conversion of waste heat to power
Inventor: HOOPER FRANK C
IPC: F01K23/04
Filed: 1996-11-19
Abstract: Conversion of heat from high-temperature off-gases into useful work is accomplished with a process having first and second stages.      The first stage comprises i) passing feed water through a counterflow feed water preheater which is heated by off-gas, to form preheated feed water; ii) converting the preheated feed water into steam in a steam boiler which is heated by off-gas; iii) superheating the steam in a steam superheater which is heated by off-gas; iv) passing the superheated steam into a steam expander which allows expansion of the superheated steam, thus producing shaft work to operate a first machine, and exhausting low pressure steam; v) feeding the low pressure steam through a steam condenser to form condensed feed water; and vi) pumping the feed water through a counterflow fluorocarbon working fluid preheater before passing the feed water through the first stage again starting at step.        The second stage comprises a) passing liquid fluorocarbon working fluid, e.g. HCFC, through the fluorocarbon working fluid preheater to preheat the liquid fluorocarbon working fluid; b) passing the preheated liquid fluorocarbon working fluid into a separator, from where liquid fluorocarbon working fluid passes through a heat exchanger in the steam condenser thus converting some of the liquid fluorocarbon into gaseous fluorocarbon, whence the mixed liquid and gas is returned to the separator in which the gas is separated from the liquid fluorocarbon;     c) superheating the gaseous fluorocarbon working fluid in a gaseous fluorocarbon superheater which is heated by off-gas; d) passing the superheated gaseous fluorocarbon working fluid through a fluorocarbon expander which allows expansion of the superheated gaseous fluorocarbon working fluid, thus producing low pressure gaseous fluorocarbon working fluid and producing shaft work to drive a second machine; e) feeding the low pressure gaseous fluorocarbon working fluid through a fluorocarbon condenser to give up its latent heat and form liquid fluorocarbon working fluid; and f) pumping the liquid fluorocarbon working fluid through the second stage again, starting at step a).      Heat is provided to the process by passing high temperature off-gas, e.g. 350 to 1100°C off-gas, in sequence through the steam superheater, the water boiler, the fluorocarbon superheater and the feed water heater.
