Title: Intelligent transient eliminator for an ignition system
Inventor: LAZAR MARK M
IPC: F23N5/24
Filed: 1994-03-24
Abstract: Abstract The present invention relates to an intelligent transient eliminator (12) which allows a gas ignition system to prevent gas valves (22) from being turned off by a pressure switch (18) in response to a transient pressure wave.  The transient eliminator (12) is preferably provided in a HVAC unit or furnace (10) which burns a fuel such as natural gas. An ignition control system employing an intelligent transient eliminator (12) provides a secondary relay (44) across the pressure switch (18).  The secondary relay (44) is controlled by a signal to an ignitor (24) in the furnace (10).  The secondary switch (44) is tested before energizing the inducer/blower (14) in the system.

Patent CA-2151475-A1 (CA)
Inventor: OLSON KEITH E
IPC: C11D3/395
Filed: 1994-01-06
Abstract: Aqueous bleach solutions can be made by directing a spray of water onto a bulk or shaped solid (brick, tablet, block, etc.) comprising a continuous solid phase of an encapsulated source of an active halogen bleach or a solid comprising a source of an oxidizing active halogen bleach, and an encapsulated oxidizing halogen bleach source. Such shaped solids can be used to dispense uniform quantities of an aqueous bleach concentrate to bleaching locus such as a washing machine. The tablets can be made from the encapsulated bleach or from a powder mixture of a particulate, granulated or powdered unencapsulated source of active oxidizing bleach and an encapsulated source of active oxidizing bleach by forming the powder mixture into a desired shape. Such a shaped solid bleach can be packaged in a container and can then be contacted with an aqueous spray in a dispenser to create a solution of active bleach for cleaning bleaching processes. The presence of the encapsulate in the solid with the powder reduces the tendency of the solid to absorb water which can be wicked through the solid to pass water through the solid into adjacent solids.  Substantial proportions of absorbed water can cause the tablets to crack, crumble and to periodically dispense uneven, substantially large and undesirable concentrations of active bleach into a wash or bleach cycle. Such large amounts of halogen can cause corrosion of metal machine or dispenser parts, clothing damage, can cause pinholing or other fabric damage, can result in color loss or change, or can result in other undesirable effects in either the dispenser, washing machine or the cleaned item.

Inventor: VLOCK ALEXANDER
IPC: B60W10/18
Filed: 1995-11-17
Abstract: A vehicle transmission system is described which employs a split power path design to achieve continuously variable speed ratios. A motor-generator unit is provided for converting a fraction of the input power into electrical power, and a second motor-generator and differential gear mechanism are employed to re-combine the two power components before transmitting the mechanical power through a gearbox. Electrical power dissipation means allows the transmission system to provide slippage when accelerating a load from rest, and it also assists in shifting and in braking. An electronic motor controller coordinates feedback signals from various sensors and controls the dynamic performance of the entire system. The motor-generators are integrated with the housing of the transmission and have water jackets to assist in heat dissipation. The motor-generator pair and the power dissipation elements are all cooled by a circulating fluid which transfers heat from these components to an external heat exchanger.

Abstract: A symmetric procedure avoids the problems with prior art systems using modifiers with master keys and generates a secure session key from a secret master key and an additional pair of randomly selected signals. The secret master key is known to both parties: one at station A and one at station B. One randomly selected signal of the pair is generated by the party at station A while the other signal in the pair is generated by the party at station B. In one embodiment, a random number signal sent by each one of the parties to the other is encrypted before transmission and decrypted upon reception. Both encryption (at one station) and decryption (at the other station) employ symmetric key cryptographic systems which use the secret master key. The session key is then formed by a commutative combination of both random number signals.

Title: Process for the manufacture of condoms
Inventor: KOPELOWICZ ALBERTO
IPC: B29C67/00
Filed: 1996-02-22
Abstract: A procedure for the manufacturing of an improved condom, featuring the making of a concentric mesh of filaments that bond into a knot at a central point, said knot coinciding with the apex or tip of the condom's matrix and the orderly stretching (combing) of said filaments in an aligned way onto the walls of said matrix through the action of one or more elastomeric "o" rings that move from the matrix's apex, where the knot gathering the filaments lies, aligning and comb-ing them until they reach the appropriate extension on the matrix. At that point, the "o" rings will come to a halt and the filaments will continue and gather together in a knot, surpassing the end of the matrix, which lies at the opposite angle of the matrix's apex.- Once this spindlelike yarn of filaments is obtained, the next step is the making of both an upper latex cap and a latex perimetrical band. The former, by briefly dipping it into latex, will be adjacent to the apex of the (condom's) matrix; the latter, i.e. the latex perimetrical band, is placed where the finishing cut for the condom's base is desired, thus the filaments are fastened at those points.-Once these coatings for fastening the filaments are finished, the next step is to di-vide and remove the angle and the knot used initially to gather the filaments - 14 -together, as well as to cut and remove the left over portion surpassing the perime-trical band, thus there's a definite removal of both the initial knot as well as the left over portion that surpassed the base perimetrical band. As a result, the remaining portion thus obtained, is ready for a final latex dip and the subsequent rolling and getting ready for packaging.-
