Abstract: ABSTRACT      A low-energy blasting initiation system, method and surface connection is disclosed for low-noise, time controlled transmission of an initiation signal from a signal initiation source to a plurality of remote blasting elements.  A connector block of the system comprises a housing having a channel formed therein for receiving a low energy detonator.  A tube engaging member is formed on an end of the housing for holding transmission tubes adjacent an end of the channel.  Tabs are formed in the channel for snap-fit retention of the detonator, and positioning cleats are formed in the channel for positioning of the detonator with an explosive end of the detonator in juxtaposed energy communicating relationship with a side of the transmission tubes.  Non-directional signal transmission is initiated in the transmission tubes in response to activation of the detonator for time-controlled transmission of the initiation signal to the remote blasting system elements.

Patent CA-2054181-A1 (CA)
Inventor: HANDA PAWAN K
IPC: B29C48/92
Filed: 1991-10-24
Abstract: A method of making an elastomer masterbatch or a compounded productive elastomer stock is provided. A twin screw extruder is used to mix elastomer components in multiple mixing zones at controlled temperatures.      Elastomer and other ingredients are fed into the twin screw extruder continuously through precise loss-in-weight or volumetric feeders. The degradation temperature and/or cross linking temperature of the elastomer determines the rate at which the elastomer can be processed, since friction created during mixing heats the elastomer. Accordingly, the maximum rate of compounding is a function of the torque limit, cooling efficiency, and conveying capacity of the extruder.      The conveying capacity and torque limit are also a function of the size of the extruder. The viscosity of the elastomer compound in the extruder, as measured by a Mooney viscosimeter (ASTM D1646), is typically in the range of about 20 to 250 units (ML(1+4)100C).

Title: Enivro-seal
Inventor: KIRBY WILLIAM
IPC: B65D88/34
Filed: 1992-03-26
Abstract: ABSTRACT A thin plate of a flexible material is to cover any liquid that may harden when exposed to the atmosphere. When the vessel is opened, and only part of the liquid is used and the vessel is resealed aqain, the atmosphere which is trapped within the closed vessel containinq the liquid will cause the liguid to harden. The thin flexible plate is lowered onto the liquid, before the vessel is resealed, thereby, cutting off any of the atmosphere remaining in the resealed vessel from the liquid. When the liguid is needed again, the thin flexible plate is removed from the top of the liquid, thereby the liguid would be free of any hardened surface. The plate can be cleaned and reused.

Filed: 1992-07-08
Abstract: In order to reduce volume and weight of a power supply of a compact portable telephone set and thus reduce the volume and weight of the compact portable telephone set itself, a P-channel power MOSFET is used as a power switching element, and a negative voltage, for example -11 volts, is applied across a source and a gate from a DC/DC converter to turn on the P-channel power MOSFET so that power is supplied from a battery which serves as one power supply.  When the gate and the source of the power MOSFET are maintained at the same potential, the power MOSFET is turned off and power is supplied from another power supply.

Patent CA-2082233-A1 (CA)
Inventor: PORTAS FRANCESCO
IPC: H02G1/14
Filed: 1992-11-05
Abstract: The enclosure  assembly, being particularly but not exclusively conceived for use over electric cable splices, comprises a sleeve of an elastomer material,  a support whereover the sleeve is  fitted in a condition of elastic expansion, said sleeve being adapted to shrink around the elongate cylindrical objects upon removal of the support. The support comprises two substantially cylindrical, tubular bodies having ends  abutted  coaxially  with  each  other  in  mutual  continuation relationship;  the abutted ends  are disposed at substantially inward locations  of  the  sleeve  longitudinal extension. Thus, the  support removal can begin from a predetermined internal region of the sleeve; the sleeve starts shrinking over the splice within said internal region, and  any  axial deformations  in  the  sleeve  would  leave  the  sleeve positioning relatively to said predetermined internal region unaffected.

Title: "sequence-specific non-photoactivated crosslinking agents which bind to the major groove of duplex dna
Inventor: MATTEUCCI MARK D
IPC: C12Q1/70
Filed: 1991-05-24
Abstract: Agents which bind to the major groove of nucleic acid duplexes in a sequence-specific manner and are capable of forming covalent bonds with one or both strands of the duplex in the absence of light are useful therapeutic agents in the treatment of conditions mediated by duplex DNA. These agents are designed so that the reactivity of the crosslinking agent does not interfere with the sequence specificity of the agent which binds to the major groove.  Thus, specific desired DNA duplexes can be targeted and their activity diminished or enhanced.

Title: Systems and methods for operating data card terminals for transaction chargeback protection
Inventor: NOBLETT PAUL W JR
IPC: G06Q20/00
Filed: 1992-12-31
Abstract: "SYSTEMS AND METHODS FOR OPERATING DATA     CARD TERMINALS FOR TRANSACTION     CHARGEBACK PROTECTION"            Abstract of the Disclosure Systems and methods for operating a data card terminal, such as a credit card transaction terminal, for providing chargeback protection services for the benefit of merchants are disclosed. The terminal includes a transaction terminal comprising an embossed character reader and magnetic stripe reader, with a separate signature capture printer. The transaction terminal is operative for detecting the physical presence of a data card during a card transaction. The embossed character reader employs a tactile imager and pattern recognition for detecting the embossed characters on the data card. A signature capturing printer prints a paper receipt, which is signed by a cardholder at a signature capturing window on the printer. A signature capturing system digitizes and compresses signals corresponding to the signature of the card holder. Transaction data including compressed signature signals and signals indicative of the presence of the card are transmitted to the host computer system of a transaction processor, who guarantees the transaction as chargeback-protected under certain circumstances. Also disclosed are methods for providing electronic and off-line transaction authorizations.

Patent CA-2088660-A1 (CA)
Title: Heat processing of a product
Inventor: OVADIA DAVID
IPC: A23L3/01
Filed: 1991-08-01
Abstract: A method and apparatus are provided for the rapid heat treatment of products, and especially gas-permeable, water-containing products such as bread dough. Baking of dough involves placing the dough within an enclosed oven or zone (1) and subjecting the dough to dielectric (e.g. radio-frequency or microwave) heating using appropriate generators (6, 7, 7a, 8a). Radiant heat from an appropriate source (9) and hot oven gases are simultaneously applied for crust formation. During at least a portion of the baking cycle, the gas pressure within the zone (1) is selectively elevated by steam addition (10) in response to the rise in gas pressure within the dough resulting from vaporization of water therein. In this way, the pressure differential between the dough interior and the ambient environment is minimized, and the dough may be rapidly baked without fear of significant dough disruption. Cooling is effected by gradually reducing the zone pressure, through use of a vacuum pump (12). If desired, vacuum cooling can occur simultaneously with continued radiant heating crust formation. The process of the invention gives completely baked and cooled bread in a matter of minutes.
