Patent CA-2254303-A1 (CA)
Inventor: RHAD EDWARD
IPC: A61B10/02
Filed: 1998-11-23
Abstract: A surgical instrument for excising a targeted tissue mass to be biopsied from adjacent bodily tissue of a surgical patient is disclosed.  The instrument has an elongated tube, a penetrating member with first and second tissue stops affixed to the distal end of the elongated tube, and a tissue cutter mounted concentrically relative to the elongated tube for movement from first to second positions for cutting captured tissue received within a tissue receiving chamber. The first and second tissue stops define the tissue receiving chamber continuously about a 360° arc at the distal end of the elongated tube for receiving the targeted tissue mass therein. Unlike conventional biopsy instruments where tissue is received within a confined lateral receiving port, a significantly larger sample size can be taken within the tissue receiving chamber. The instrument is adapted for taking sufficiently sized samples to be biopsied in a minimally invasive manner, minimizing or avoiding trauma adjacent the biopsy site.

Title: Awning extension and retraction mechanism
Inventor: FREY SYDNEY W JR
IPC: B60P3/345
Filed: 1999-03-19
Abstract: An awning includes a roller assembly having a torsion spring, a canopy connected between a wall the roller assembly, and a pair of "four-bar" arm assemblies supporting opposite ends of the roller assembly. The arm assemblies move the roller assembly between a retracted position and an extended position, where the torsion spring biases the roller assembly toward the retracted position. Each arm assembly includes a vertically extending base arm secured to the wall, a bottom arm having a first end pivotally connected to the base arm, an extended arm having a first end pivotally connected to the bottom arm and a second end supporting the roller assembly, and a top arm having a first end pivotally connected to the base arm and a second end pivotally connected to the extended arm. The base arm has a telescoping extension so that the effective length of the base arm is variable. Each arm assembly also includes a force producing member extending between the base arm and the bottom or top arm to move the arm assembly toward the extended position. In a preferred powered automatic awning, the force producing member is an electric linear actuator extending between the base arm and the bottom arm. A counter-balance spring biases the arm assembly toward the extended position to counter-balance the torsion spring. In a preferred spring-assisted manual awning, a tension coil spring extends between the base arm and the bottom arm to counter-balance the torsion spring, or a compression spring suitably mounted to create tension between the base arm and the bottom arm. In another preferred spring-assisted manual awning, a compression gas spring extends between the base arm and the top arm to counter-balance the torsion spring.

Patent CA-2277887-A1 (CA)
Inventor: LEE RALPH D
IPC: A23G1/48
Filed: 1998-01-09
Abstract: Improved methods of making chocolates utilizing fast and aggressive cooling to form a set chocolate, chocolate products produced using same and cooling systems and apparatuses for performing same. The resultant rapidly cooled chocolate has many improved properties including enhanced gloss, improved bloom resistance and hardness. Moreover, the rapid cooling allows for the improved retention of fine detail and/or decoration of the chocolate product. The rapid cooling can be achieved without the use of chilled plungers or cold molds, but instead utilizes increased convective heat transfer coefficients and/or lower operating temperatures. The melted chocolate composition set by the rapid cooling can be of conventional temper, low temper or ultra-low temper chocolate and still result in a stable finished chocolate product allowing for the use of lower fat content formulations. Another aspect of the invention relates to a method of using a controlled humidity environment in a rewarm zone after the cooling zone to form a thermally robust chocolate product having enhanced resistance to heat abuse, yet which still has good gloss.

Title: Serial data- and control-bus with distribution voltage
Inventor: MELCHER DOMENIC
IPC: G06F13/38
Filed: 1998-10-09
Abstract: The invention relates to a bus system for the serial transmission of digital data with a multiplicity of individual addressable bus transceivers (BT), which are connected by an only two-wire common bus, via which both synchronizing signals and also digital data and energy are exchanged between the BTs. As the value of a bit, the result of an elementary logical operation (AND or OR) on the values of all simultaneously transmitting BTs with the same address is transmitted to all the receiving BTs with the same address simultaneously. Each BT includes its own time control and synchronizing circuit with a time base, a bit counter, a byte counter and a comparator with an identity between the imprinted address and that appearing on the bus a byte of digital data is transmitted serially via an I/O  port. The bus system can be put into operation and operated without the use of software, whereby polarization errors in installation are excluded.
