Title: Magnetic device for converting reciprocating into rotating motion
Inventor: RIGAZZI PIER ANDREA
IPC: F02B3/06
Filed: 1992-06-29
Abstract: The method allows to move, for exam-ple with a rotative motion, a member or a group of members by moving another member or group of members with a reciprocating rec-tilineal motion by means of the interaction be-tween magnets (1, 2) or groups of magnets (1i, 2i) fixed to the said members or group, of members. If the reciprocating rectilineal mo-tion is obtained by connecting one of the two groups of magnets to the pistons of a re-versed-star two stroke engine and to a me-chanical energy restituting system (8), a high-efficiency propulsing means is realized, which is suitable for engine-traction, which does not need a crank-shaft, a lubricating system; water cooling system; alternator or torque converter; and is automatically switched off when the vehicle is not in mo-tion. Its work-torque can be varied by vary-ing the distance between said restituting sys-tem (8) and members (14) named cursors, connected to pistons (5). Easy and cheap to make, it causes little-pollution and is suit-able even for using hydrogen as fuel. In which case, its pollution products are insign-ificant or equal to zero.

Patent CA-2118780-A1 (CA)
Inventor: HARWOOD JON W
IPC: F01N1/02
Filed: 1994-03-10
Abstract: A muffler and a method of manufacturing a muffler are provided. The muffler includes a pair of stamp formed laminated external shells, each of which includes inner and outer layers.          The inner and outer layers are stamped simultaneously to nest with one another.   However, the respective layers of each laminated shell will spring back slightly differently from one another in view of different metallurgical characteristics inherent in each sheet.   The laminated external shells are then disposed around internal components of the muffler, and peripheral regions are securely  clamped  together.    This  clamping,  in  view  of  the differential spring-back creates a narrow air chamber between the layers of each laminated external shell.  Peripheral regions are then laser welded together to hermetically seal the narrow air chamber  between  the  layers  of  each  external  shell.    The hermetically sealed air chamber effectively dampens vibrations of the  external  shells  and  contributes  to  both  heat  and  noise insulation from interior regions of the muffler.

Title: Optical bus transmission method and transmitting-side encoder and receiving-side decoder therefor
Inventor: KAHARU TAKEO
IPC: H04L29/10
Filed: 1991-06-19
Abstract: The present invention relates to an optical bus transmission method wherein each terminal connected to an optical bus produces a narrow pulse synchronized with the rise of a leading pulse of a second one of first and second Manchester-biphase digital electric signals, a narrow pulse synchronized with the rise of each pulse of the first digital electric signal and a narrow pulse occurring every fixed period of time during the duration of each pulse.  The method is comprised of a step wherein the narrow pulses are converted into optical signals and transmitted as an optical pulse train to the optical bus, and a step wherein each terminal converts an optical pulse received from the optical bus into an electric pulse signal.  The method further includes a step wherein the electric signal is separated into its leading pulse and subsequent pulses. Each of the subsequent pulses is converted into a pulse of a pulse width equal to the fixed period of time to regenerate the first digital electric signal and the second digital electric signal is regenerated from a polarity-inverted version of the regenerated first digital electric signal and the leading pulse.

Inventor: MENASHE JULIAN
IPC: G06F19/00
Filed: 1994-05-18
Abstract: The gaming system includes a host computer, a plurality of general purpose terminal computers forming player stations remote from the host, means for providing communication between each of the terminals and the host. Each terminal has a program for generating screen graphics and sound locally in response to control data packets generated by and received from the host. The host generates random numbers for a game being played on a connected terminal within preset criteria for that game in response to data packets received from the terminal. The data packets are of variable length between 1 and 80 bytes. The host sequentially stores the minimum significant information for replaying a game, auditing and security, such as accounting data of each player at the start of each game, random numbers generated by the host, responses received from a player, and whether a game was completed. Play is substantially real-time, because only minimal data is transmitted with functions requiring large amounts of data, such as screen graphics being generated locally. The statuses of host and terminal are restored automatically on re-establishing communication following an interruption to ensure fairness to players and prevent them defeating the outcome of a game.
